Definitions
- the present invention can be used irrespective of the degree of flatness or shape of the surface to be adsorbed, or the temperature change of the season, and also provides a strong vacuum adsorption force by reliably inducing air discharge in the space between the surface to be adsorbed during the adsorption process. It relates to a vacuum suction port.
- the vacuum suction port uses a vacuum suction force of the sucker to suck various objects by vacuum suction even on a smooth wall surface, glass or flat tile, and a suction surface having a slight uneven surface such as a dashboard of a vehicle. It is used for fixed support, and is widely used for various purposes in various fields such as home or office. Since the vacuum suction port adopts a structure in which the suction surface is vacuum-adsorbed to the suction surface, anyone can easily attach or detach the suction surface to the suction surface without using any tools. Its use is gradually increasing due to its advantages and ease of use. In addition, due to the advantages and convenience of the above-mentioned vacuum adsorption chamber, vacuum adsorption spheres having various shapes and structures are also being developed and presented.
- vacuum suction holes that have been proposed in the past may be significantly limited in use depending on the flatness of the suction surface due to the material of the suction plate or the limitation of the absorption structure.
- the adsorption efficiency is significantly reduced, the situation is required to be improved.
- vacuum adsorption ports have been proposed that can be used regardless of the flatness of the surface to be adsorbed. It is true.
- the vacuum adsorption ports proposed in recent years also have various vacuum adsorption ports, but have not been satisfactory. That is, the structure of the vacuum suction port mainly consists of a plurality of suction plates to increase the vacuum suction force on the sucker, or the sucker is sucked on the suction surface by elastically pressurizing the sucker in a one-touch manner with a screw type or a spring-loaded push cap. As the structural improvement is being made, the effect of increasing the vacuum adsorption force is increased to a certain extent, but the formation and maintenance of stable vacuum adsorption force on the adsorption surface having high unevenness due to the material limitation of the sucker body is expected. It is difficult.
- the material of the sucker is mainly composed of a medium polyvinyl chloride (PVC) or a silicon material
- the material to be adsorbed has a smooth glass surface or a wall surface.
- PVC medium polyvinyl chloride
- the adsorption surface formed of fine wrinkles, irregularities, and rough shape has high hardness due to the material's characteristics, so vacuum adsorption is not possible because the adsorption is not completely filled in the gap between each irregularities during vacuum adsorption. The retention of is bound to fall.
- the adhesion force is greatly reduced due to the temperature change due to the characteristics of the material. Due to various structural problems such as difficulty in maintenance or loss, it is difficult to avoid problems in which the use thereof is limited or the use efficiency is greatly reduced.
- a sucker has been proposed in which a soft rubber or a soft synthetic resin soft material is polymerized on the inner circumferential surface of the sucker body made of a hard material made of hard rubber or a soft synthetic resin material so that the adsorption force on the suction surface is somewhat improved (Japanese Utility Model Publication). So 59-166015).
- a sucker in which the sucker is adsorbed to the adsorbate is separately introduced between the sucker and the adsorbate by separating the adsorption auxiliary plate for the sucker of the elastomer (Korean Patent Publication No. 10-2008-0103891).
- the adsorption plate of the sucker and the elastomer has a separate structure, which raises the question of generation of vacuum adsorption force between the sucker and the adsorption plate in the structural state of the sucker. It is difficult to avoid the problems caused by discomfort.
- a one-touch vacuum suction port made of a polypropylene (PP: polypropylene) material, and the entire outer circumferential surface thereof is covered with only polyvinyl chloride (PVC) (Korean Patent Publication No. 10-2010).
- PP polypropylene
- PVC polyvinyl chloride
- the sucker has a problem in that the injection moldability is remarkably inferior because the physical properties of the sucker body and the coating material are different, and the coating materials for the sucker body are separated from each other.
- Shoha's hardness is 45 ⁇ 55, it provides a relatively hard adsorption surface, so that the vacuum adsorption force on the adsorption surface is inevitably deteriorated.
- the hardness of the adsorption surface is high, so it is difficult to penetrate into the uneven surface, so it is difficult to maintain a solid adsorption force, and thus there is a limit that can be used only on the smooth surface.
- polyvinyl chloride (PVC) which is a coating material, is sensitive to seasonal temperature changes, so there is a limit that it is impossible to continuously use it when the temperature change is severe.
- the pressure of the press plate is simply discharged to the air between the adsorption surface through the degree of pressurization, so that the air is not discharged reliably, thereby providing a strong vacuum adsorption force on the adsorption surface. Difficult to avoid.
- the various types of vacuum adsorption or suckers proposed in the related art have a single or various materials and shapes, but the adsorption force considering the flatness of the surface to be adsorbed is only slightly improved, and according to the seasonal temperature change. It is difficult to avoid many complex problems, such as the ability to cope with air and the ability to evacuate the air significantly, to provide a strong and lasting adsorption force, and to make installation on the adsorption surface somewhat uncomfortable. It is true.
- the present invention has been invented to solve various problems posed by the conventional vacuum adsorption holes, and an object of the present invention is not only to make the adsorption layer of the sucker adsorbed on the surface to be adsorbed low hardness, good adhesion and soft, It is formed of an elastomer that is hardly affected by temperature changes, and thus it can be used without any problems in the degree of flatness of the adsorption surface or seasonal temperature change. It is to provide a vacuum suction port that can be surely made to enable the formation and maintenance of a strong vacuum suction force.
- the pressing cap when the vacuum adsorption to the surface to be adsorbed, the pressing cap is lowered and rotated to provide some time for the air present in the space between the surface to be adsorbed to be discharged to the outside, and then the press cap is returned to its original state.
- adsorption it is not only possible to provide a strong vacuum adsorption force on the surface to be adsorbed, but also the adsorption layer of the sucker adsorbed on the surface to be adsorbed is formed of an elastomer having low hardness, good adhesion and softness, and being hardly affected by temperature changes. By doing so, it is possible to maintain and maintain firm adhesion and adsorption at all times without any problem even with the degree of flatness of the surface to be absorbed or the temperature change of the season.

It is manufactured by the second injection molding step (S300) of the adsorption layer 26 to a predetermined thickness by using an elastomer having a low hardness.
- the coating layer 24 and the adsorption layer which are injection-molded with an elastomer having different adsorption and adsorption operation plates 22 and Showa hardness (shore A) which are injection molded from a polypropylene material, respectively Since the 26 have the same physical properties, the coating layer 24 and the adsorption layer 26, which are integrally injection-molded on the upper and lower sides of the adsorption operation plate, can be integrally injection-fused without being separated from each other.

- the adsorption layer 26 is most preferably manufactured to be integrally fused within the range of 1.5-2 mm thickness t, as shown in FIG. 3. Because, as a result of the adsorption test, when the thickness becomes thinner than the above-mentioned thickness, the adhesion to the adsorption surface W, which is roughly uneven, that is, the degree of digging into the uneven surface W2 is weak, which makes it impossible to provide a firm adhesion force. There is.
- the fusion is thicker than the above-mentioned thickness is not particularly limited, but because the elastomer material is expensive, it may cause problems such as the increase in manufacturing cost and the problem that the overall load or volume of the sucker becomes larger than necessary, it is recommended. It's not worth it.

Description
본 발명은 피 흡착면의 평탄 정도나 형태, 계절의 온도 변화에 관계없이 사용 가능할 뿐 아니라 흡착 과정에서 피 흡착면과의 사이의 공간에 존재하는 공기 배출을 확실하게 유도하여 강한 진공 흡착력을 제공하도록 한 진공 흡착구에 관한 것이다.The present invention can be used irrespective of the degree of flatness or shape of the surface to be adsorbed, or the temperature change of the season, and also provides a strong vacuum adsorption force by reliably inducing air discharge in the space between the surface to be adsorbed during the adsorption process. It relates to a vacuum suction port.
일반적으로 진공 흡착구는 흡반의 진공 흡착력을 이용하여 매끄러운 벽면이나, 유리, 또는 평면 타일을 비롯하여 차량의 데시보드 등 약간의 요철면이 형성되어 있는 피 흡착면이라 하더라도 이에 진공 흡착시켜 각종 물건을 걸거나 고정 지지하는 용도로 사용되는 것으로서, 가정이나 사무실 등 각종 분야에서 다양한 용도로 널리 이용되고 있는 실정이다. 이러한 진공 흡착구는 흡반을 통해 피 흡착면에 진공 흡착되는 구조를 채용하고 있기 때문에 별도의 공구를 이용하지 않으면서도 누구나가 간편하게 피 흡착면에 대해 탈부착시킬 수 있고, 또 피 흡착면의 손상을 최대한으로 피할 수 있다는 장점과 사용 편리성에 의해 그 이용이 점차적으로 증가하고 있는 추세에 있다. 그리고, 상기한 진공 흡착구의 장점과 편리성에 의해 다양한 형태와 구조를 갖는 진공 흡착구가 개발 제시되고 있는 실정이기도 하다.In general, the vacuum suction port uses a vacuum suction force of the sucker to suck various objects by vacuum suction even on a smooth wall surface, glass or flat tile, and a suction surface having a slight uneven surface such as a dashboard of a vehicle. It is used for fixed support, and is widely used for various purposes in various fields such as home or office. Since the vacuum suction port adopts a structure in which the suction surface is vacuum-adsorbed to the suction surface, anyone can easily attach or detach the suction surface to the suction surface without using any tools. Its use is gradually increasing due to its advantages and ease of use. In addition, due to the advantages and convenience of the above-mentioned vacuum adsorption chamber, vacuum adsorption spheres having various shapes and structures are also being developed and presented.
하지만, 종래 제시되고 있는 일부 진공 흡착구는 흡반의 재질이나 흡착 구조의 한계로 인해 피 흡착면의 평탄 정도에 따라 그 사용이 현저하게 제한되는 경우도 있고, 특히 피 흡착면이 요철 형태를 이루고 있는 경우에는 그 흡착 효율이 현저하게 저하되는 문제로 인해 이에 대한 개선이 요구되고 있는 실정이라 하겠으며, 이러한 점을 감안하여 근자에는 피 흡착면의 평탄 정도에 관계없이 사용 가능하도록 한 진공 흡착구들이 제시되고 있는 실정이다.However, some of the vacuum suction holes that have been proposed in the past may be significantly limited in use depending on the flatness of the suction surface due to the material of the suction plate or the limitation of the absorption structure. In this regard, due to the problem that the adsorption efficiency is significantly reduced, the situation is required to be improved. In view of this, in recent years, vacuum adsorption ports have been proposed that can be used regardless of the flatness of the surface to be adsorbed. It is true.
그러나, 근자에 제시되고 있는 진공 흡착구들 역시, 다양한 진공 흡착구가 제시되고는 있지만, 만족할 만한 효과는 거두지 못하고 있다. 즉, 진공 흡착구의 구조가 주로 흡반에 대한 진공 흡착력을 높이기 위해 흡착판을 복수 개로 구성하거나, 또는 흡반을 나사 방식 또는 스프링이 개재된 누름 캡을 원터치 방식으로 탄성 가압하여 흡반이 피 흡착면에 대해 흡착되도록 하는 정도로의 구조 개선이 이루어지고 있는 것이어서, 진공 흡착력이 어느 정도 상승되는 정도의 효과는 거두고 있지만 흡반 본체의 재질 한계로 인해 요철이 심한 피 흡착면에 대한 안정된 진공 흡착력의 형성 및 유지는 기대하기 어려운 실정이다. 그리고, 종래 제시되고 있는 진공 흡착구의 경우 흡반의 소재가 중경질의 폴리염화비닐(PVC:polyvinyl chloride) 또는 실리콘재질로 이루어진 것이 주로 사용되고 있기 때문에 소재의 특성상 피 흡착면이 매끄러운 유리면이나 벽면인 경우에는 어느 정도 양호한 흡착력이 발휘되지만, 잔주름 형태이거나 요철 형태, 까칠 까칠한 형태로 이루어진 피 흡착면의 경우에는 소재 특성상 경도가 높아 진공 흡착시 각 요철 사이의 틈새를 완전히 메꾸는 상태로 흡착되지 못하기 때문에 진공 흡착력의 유지가 저하될 수밖에 없다. 특히 상기한 폴리염화비닐(PVC) 또는 실리콘(silicon)재질로 이루어진 진공 흡착구의 경우에는 소재 특성상 온도 변화에 따른 밀착력이 크게 저하되기 때문에 온도가 낮아지는 경우에는 딱딱하게 굳는 정도가 더욱 심하여 견고한 흡착력의 유지가 곤란하거나 상실하게 되는 등의 여러 가지 구조적인 문제로 인해 그 사용이 제한적이거나 또는 이용 효율이 크게 저하되는 문제를 피하기 어려웠던 것이다.However, the vacuum adsorption ports proposed in recent years also have various vacuum adsorption ports, but have not been satisfactory. That is, the structure of the vacuum suction port mainly consists of a plurality of suction plates to increase the vacuum suction force on the sucker, or the sucker is sucked on the suction surface by elastically pressurizing the sucker in a one-touch manner with a screw type or a spring-loaded push cap. As the structural improvement is being made, the effect of increasing the vacuum adsorption force is increased to a certain extent, but the formation and maintenance of stable vacuum adsorption force on the adsorption surface having high unevenness due to the material limitation of the sucker body is expected. It is difficult. In the case of the vacuum adsorption port proposed in the related art, since the material of the sucker is mainly composed of a medium polyvinyl chloride (PVC) or a silicon material, the material to be adsorbed has a smooth glass surface or a wall surface. Although good adsorption power is exhibited, the adsorption surface formed of fine wrinkles, irregularities, and rough shape has high hardness due to the material's characteristics, so vacuum adsorption is not possible because the adsorption is not completely filled in the gap between each irregularities during vacuum adsorption. The retention of is bound to fall. In particular, in the case of the vacuum suction port made of the polyvinyl chloride (PVC) or silicon (silicon) material, the adhesion force is greatly reduced due to the temperature change due to the characteristics of the material. Due to various structural problems such as difficulty in maintenance or loss, it is difficult to avoid problems in which the use thereof is limited or the use efficiency is greatly reduced.
그외에도 경질 고무 혹은 연질합성수지재의 경질소재로 이루어지는 흡반 본체의 내주면에 연질고무 또는 연질합성수지의 연질재료를 중합 배치하여 피 흡착면에 대한 흡착력이 다소 개선되도록 한 흡반이 제시된바 있다(일본 실용신안공개 소59-166015호 공보).In addition, a sucker has been proposed in which a soft rubber or a soft synthetic resin soft material is polymerized on the inner circumferential surface of the sucker body made of a hard material made of hard rubber or a soft synthetic resin material so that the adsorption force on the suction surface is somewhat improved (Japanese Utility Model Publication). So 59-166015).
또한, 흡반과 피 흡착물과의 사이에 엘라스토머(elastomer)의 흡반용 흡착 보조판을 별도로 분리 개재하여 흡반이 피 흡착물에 흡착되도록 한 흡반이 소개되고는 있으나(한국 특허공개 제10-2008-0103891호 공보), 이는 흡반과 엘라스토머의 흡착 보조판이 별도로 분리된 구조를 이루고 있어 흡반의 구조상 분리 상태에 있는 흡반과 흡착 보조판과의 사이의 진공 흡착력 발생에 의문이 드는 것을 비롯하여 제품의 취급 및 설치에 따른 불편함이 초래되는 문제를 피하기 어렵다는 것이다.In addition, a sucker in which the sucker is adsorbed to the adsorbate is separately introduced between the sucker and the adsorbate by separating the adsorption auxiliary plate for the sucker of the elastomer (Korean Patent Publication No. 10-2008-0103891). This is because the adsorption plate of the sucker and the elastomer has a separate structure, which raises the question of generation of vacuum adsorption force between the sucker and the adsorption plate in the structural state of the sucker. It is difficult to avoid the problems caused by discomfort.
또한, 흡반 본체를 폴리프로필렌(PP:polypropylene)소재로 제작하고, 그 외주면 전체를 폴리염화비닐(PVC)로만 감싸지도록 피복한 원터치 방식의 진공 흡착구가 제시되고 있으나(한국 특허공개 제10-2010-0108176호 공보), 상기한 흡반은 흡반 본체와 피복소재의 물성이 서로 달라 사출 성형성이 현저하게 떨어지고, 흡반 본체에 대한 피복 물질이 서로 분리되는 상태로 사출되는 문제가 있을 뿐 아니라 피복 소재의 쇼하 경도가 45~55 정도이어서 비교적 딱딱한 흡착면을 제공하게 됨에 따라 피 흡착면에 대한 진공 흡착력이 현저하게 떨어질 수밖에 없다. 또한 요철이 심한 피 흡착면의 경우에는 흡착면의 경도가 높아 요철면에 파고들어가지 못하기 때문에 견고한 흡착력의 유지가 곤란하게 되어 매끈한 면에만 제한적으로 사용될 수밖에 없는 한계가 있다. 또한 피복소재인 폴리염화비닐(PVC)은 계절의 온도 변화에 민감하게 반응하기 때문에 온도 변화가 심한 경우에는 지속적으로 사용하는 것이 불가능하다는 한계가 있다. 그리고, 누름판을 단순히 원터치 방식으로 가압하는 정도를 통해 피 흡착면과의 사이 공간의 공기를 배출시키는 것이어서, 공기의 배출이 확실하게 이루어지지 못하기 때문에 피 흡착면에 대한 강력한 진공 흡착력을 제공하는데 구조적인 한계를 피하기 어렵다.In addition, there has been proposed a one-touch vacuum suction port made of a polypropylene (PP: polypropylene) material, and the entire outer circumferential surface thereof is covered with only polyvinyl chloride (PVC) (Korean Patent Publication No. 10-2010). -0108176), the sucker has a problem in that the injection moldability is remarkably inferior because the physical properties of the sucker body and the coating material are different, and the coating materials for the sucker body are separated from each other. As Shoha's hardness is 45 ~ 55, it provides a relatively hard adsorption surface, so that the vacuum adsorption force on the adsorption surface is inevitably deteriorated. In addition, in the case of the adsorption surface with high unevenness, the hardness of the adsorption surface is high, so it is difficult to penetrate into the uneven surface, so it is difficult to maintain a solid adsorption force, and thus there is a limit that can be used only on the smooth surface. In addition, polyvinyl chloride (PVC), which is a coating material, is sensitive to seasonal temperature changes, so there is a limit that it is impossible to continuously use it when the temperature change is severe. In addition, the pressure of the press plate is simply discharged to the air between the adsorption surface through the degree of pressurization, so that the air is not discharged reliably, thereby providing a strong vacuum adsorption force on the adsorption surface. Difficult to avoid.
따라서, 종래 제시되고 있는 각종 형태의 진공 흡착구나 흡반은 단일 또는 다양한 소재와 형태를 갖추고는 있으나, 피 흡착면에 대한 평탄 정도를 고려한 흡착력이 다소 개선되는 정도에 불과하고, 계절의 온도 변화에 따른 대응 능력 및 진공을 위한 공기 배출 능력이 현저하게 떨어져 여전히 강력하고도 지속적인 흡착력을 제공하는 데는 한계가 있고, 또 피 흡착면에 대한 설치가 다소 불편하게 되는 등의 여러 가지 복합적인 문제를 피하기 어려운 것이 사실이다.Therefore, the various types of vacuum adsorption or suckers proposed in the related art have a single or various materials and shapes, but the adsorption force considering the flatness of the surface to be adsorbed is only slightly improved, and according to the seasonal temperature change. It is difficult to avoid many complex problems, such as the ability to cope with air and the ability to evacuate the air significantly, to provide a strong and lasting adsorption force, and to make installation on the adsorption surface somewhat uncomfortable. It is true.
본 발명은 상기 종래의 진공 흡착구들에서 제기되고 있는 제반 문제점들을 해결하기 위하여 발명한 것으로서, 본 발명의 목적은 피 흡착면에 흡착되는 흡반의 흡착층을 경도가 낮고, 점착성이 양호하고 부드러울 뿐 아니라 온도 변화에 거의 영향을 받지 않는 엘라스토머로 형성하여 피 흡착면의 평탄 정도나 계절의 온도 변화에도 전혀 문제없이 사용 가능하고, 또 흡착층과 피 흡착면과의 사이 공간에 존재하는 공기의 배출이 보다 확실하게 이루어지도록 하여 강력한 진공 흡착력의 형성 및 유지가 가능하도록 한 진공 흡착구를 제공함에 있다.The present invention has been invented to solve various problems posed by the conventional vacuum adsorption holes, and an object of the present invention is not only to make the adsorption layer of the sucker adsorbed on the surface to be adsorbed low hardness, good adhesion and soft, It is formed of an elastomer that is hardly affected by temperature changes, and thus it can be used without any problems in the degree of flatness of the adsorption surface or seasonal temperature change. It is to provide a vacuum suction port that can be surely made to enable the formation and maintenance of a strong vacuum suction force.
본 발명에 따르면, 피 흡착면에 대한 진공 흡착시 누름 캡을 하강 및 회전 작동시켜 피 흡착면과의 사이 공간에 존재하는 공기가 외부로 배출되는 시간을 어느 정도 제공한 다음 누름 캡을 원상 복귀시켜 흡착함으로써 피 흡착면에 대한 강력한 진공 흡착력을 제공하는 것이 가능할 뿐 아니라 피 흡착면에 흡착되는 흡반의 흡착층이 경도가 낮고, 점착성이 양호하며 부드러울 뿐 아니라 온도 변화에 거의 영향을 받지 않는 엘라스토머로 형성하여 줌으로써 피 흡착면의 평탄 정도나 계절의 온도 변화에도 전혀 문제없이 항상 견고한 밀착 및 흡착성을 제공 유지하는 것이 가능하게 된다.According to the present invention, when the vacuum adsorption to the surface to be adsorbed, the pressing cap is lowered and rotated to provide some time for the air present in the space between the surface to be adsorbed to be discharged to the outside, and then the press cap is returned to its original state. By adsorption, it is not only possible to provide a strong vacuum adsorption force on the surface to be adsorbed, but also the adsorption layer of the sucker adsorbed on the surface to be adsorbed is formed of an elastomer having low hardness, good adhesion and softness, and being hardly affected by temperature changes. By doing so, it is possible to maintain and maintain firm adhesion and adsorption at all times without any problem even with the degree of flatness of the surface to be absorbed or the temperature change of the season.

도 7 내지 도 9를 참조하면, 본 발명에 따른 흡반(20)은, 흡반 본체에 대하여 경도가 다른 엘라스토머를 순차적으로 사출 성형하여 피 흡착면(W)에 대한 평탄 정도나 계절의 변화에 따른 온도에 전혀 영향을 받지 않고 항상 안정된 진공 흡착 및 밀착력을 제공하도록 제조됨에 그 특징이 있는 것이다.Referring to FIGS. 7 to 9, the sucker 20 according to the present invention is sequentially molded by molding elastomers having different hardness with respect to the sucker main body, and the temperature according to the change in the degree of flatness or the season with respect to the suction surface W. FIG. It is characterized by being manufactured to provide stable vacuum adsorption and adhesion without any influence at all.
본 발명에 따른 흡반(20)은, 피 흡착면(W)에 대한 진공 흡착시 탄성 변형이 가능하도록 원반(disk) 형상으로 이루어지고, 중앙 상면으로 돌출봉(21)이 일체로 입설되도록 폴리프로필렌(PP) 소재를 이용하여 흡착 조작용 판재(22)를 압출 성형하는 단계(S100)와,The sucker 20 according to the present invention has a disk shape to enable elastic deformation during vacuum suction on the suction surface W, and a polypropylene to integrally protrude the protruding rod 21 into the central upper surface. (PP) extrusion molding the plate material 22 for the adsorption operation using the material (S100),
상기 폴리프로필렌(PP) 소재로 사출 성형되는 흡착 조작용 판재(22)의 돌출봉(21) 상단이 외부로 노출되도록 상면(22a)을 포함하여 가장자리 둘레 측면(22b)을 경도가 높은 엘라스토머를 이용하여 소정의 형상 및 두께로 피복하는 피복층(24)을 1차로 사출 성형하는 단계(S200), 및 An elastomer having a high hardness on the circumferential side surface 22b, including an upper surface 22a, to expose the upper end of the protruding rod 21 of the adsorption manipulation plate 22 that is injection-molded with the polypropylene (PP) material to the outside. By injection molding the coating layer 24 covering the predetermined shape and thickness in a first step (S200), and
상기 피복층(24)이 형성된 흡착 조작용 판재(22)의 하면(22c) 전체를 포함하여 피복층의 가장자리 둘레 측면과 일부가 중첩되도록 하여 피 흡착면(W)의 평탄 정도에 관계없이 안정된 밀착성을 제공하도록 경도가 낮은 엘라스토머를 이용하여 흡착층(26)을 소정 두께로 2차 사출 성형하는 단계(S300)를 포함하여 제조된다.Including the entire lower surface 22c of the adsorption manipulation plate 22 on which the coating layer 24 is formed, a portion overlaps with the edge circumferential side of the coating layer to provide stable adhesion regardless of the degree of flatness of the surface to be adsorbed. It is manufactured by the second injection molding step (S300) of the adsorption layer 26 to a predetermined thickness by using an elastomer having a low hardness.
본 발명에 따른 흡반(20)의 제조에서, 폴리프로필렌소재로 사출 성형되는 흡흡착 조작용 판재(22)와 쇼와경도(shore A)가 상이한 엘라스토머로 각각 사출 성형되는 피복층(24) 및 흡착층(26)은 서로 동일한 물리적 성질을 가지고 있기 때문에 상기 흡착 조작용 판재를 중심으로 이들의 상 하부에 일체로 사출 성형되는 피복층(24) 및 흡착층(26)은 서로 분리됨 없이 일체로 사출 융착되어 질 수 있는 것이며, 특히 흡착층(26)의 하면은 상기 흡착 조작용 판재(22)의 하면과 동일한 원반 형상이 유지되어지는 것이다.In the manufacture of the sucker 20 according to the present invention, the coating layer 24 and the adsorption layer which are injection-molded with an elastomer having different adsorption and adsorption operation plates 22 and Showa hardness (shore A) which are injection molded from a polypropylene material, respectively Since the 26 have the same physical properties, the coating layer 24 and the adsorption layer 26, which are integrally injection-molded on the upper and lower sides of the adsorption operation plate, can be integrally injection-fused without being separated from each other. In particular, the lower surface of the adsorption layer 26 is the same disk shape as that of the lower surface of the adsorption operation plate 22.
따라서, 피 흡착면(W)에 대한 흡반(20)의 진공 흡착시 상기한 흡착층(26)은 원반 형상을 갖는 흡착 조작용 판재(22)의 탄성 작용을 통해 원활한 진공 흡착 작용이 이루어지게 된다. 즉, 흡착 조작용 판재(22)가 도면상 중앙을 중심으로 오목하게 형성되어 있기 때문에 중심부를 강제로 부르는 경우 항상 원상으로 복귀하려는 힘이 작용하고 있기 때문이다.Therefore, when the vacuum adsorption of the sucker 20 on the suction surface W is performed, the suction layer 26 has a smooth vacuum suction action through the elastic action of the suction plate 22 having a disk shape. . That is, since the adsorption | suction operation board | plate material 22 is formed in concave centering on the drawing center, when a center part is forcibly called, the force which tries to return to a circular shape always acts.
한편, 본 발명에 따르면 흡반(20)을 구성하는 흡착 조작용 판재(22)로는 피복층(24) 및 흡착층(24)의 형성시 엘라스토머의 사출 성형성을 높이기 위한 작은 구멍(23a)이나 미세한 돌기들(23b)이 형성되어 질 수도 있다.On the other hand, according to the present invention, the plate 22 for adsorption operation constituting the sucker 20 is a small hole 23a or minute projections for enhancing the injection moldability of the elastomer during formation of the coating layer 24 and the adsorption layer 24. The fields 23b may be formed.
그리고, 흡착 조작용 판재(22)는 폴리프로필렌(PP) 소재로 압출 성형되는 것이 가장 바람직하나, 이와 동일한 물성을 가지면서도 열에 강한 성질을 갖는 복합폴리프로필렌의 대체 사용도 무방하다.In addition, the adsorption operation plate 22 is most preferably extruded from a polypropylene (PP) material, but may be replaced by a composite polypropylene having the same physical properties and heat-resistant properties.
또한, 본 발명에 따르면, 흡착 조작용 판재(22)의 상 하면으로 경도를 달리하여 일체로 융착 형성되는 엘라스토머의 피복층(24)은 쇼와경도가 60~70(shore A)이고, 흡착층(26)은 쇼와경도가 10~15(shore A) 가 되도록 구성됨이 바람직하다.In addition, according to the present invention, the coating layer 24 of the elastomer which is integrally fused and formed by varying the hardness on the upper and lower surfaces of the plate 22 for adsorption operation has a Showa hardness of 60 to 70 (shore A), and the adsorption layer ( 26) is preferably configured so that the Showa hardness is 10 ~ 15 (shore A).
상기한 피복층(24) 및 흡착층(26)의 경도를 각각 달리하여 제조하는 이유는, 피복층의 경도가 상기한 수치 이하로 낮아지게 되는 경우에는 흡착 조작용 판재(22)에 대한 일정한 텐션력의 제공 및 유지가 곤란하게 된다는 문제가 있고, 또 흡착층(26)의 경도가 상기한 범위 이상으로 높아지게 되는 경우에는 피 흡착면(W)에 대한 양호한 밀착성을 제공하는데 한계가 있기 때문에 흡반(10)의 흡착 테스트 결과 피복층(24) 및 흡착층(26)의 경도는 상기한 범위를 유지하는 것이 가장 바람직한 것으로 나타났다.The reason for manufacturing the coating layer 24 and the adsorption layer 26 by varying the hardness of each is that, when the hardness of the coating layer is lowered below the above-mentioned value, a constant tension force on the plate 22 for adsorption operation When the hardness of the adsorption layer 26 becomes higher than the above-mentioned range, when providing and maintaining becomes difficult, since there exists a limit in providing favorable adhesiveness to the to-be-adsorbed surface W, the sucker 10 The adsorption test of showed that the hardness of the coating layer 24 and the adsorption layer 26 maintained the said range most preferable.
이를 좀더 상술하면, 상기 흡착층(26)의 쇼와경도가 10~15 보다 높아지는 경우에는 피 흡착면(W)에 대한 점착성이 떨어져, 예컨대 흡착층이 딱딱한 성질을 가지게 되어 부드럽고 소프트한 밀착성을 제공하는 것이 곤란하고, 이와는 반대로 쇼와 경도가 10~15 보다 낮아지는 경우에는 부드럽고 소프트한 정도는 강화되지만 오히려 점성이 너무 낮아져 피 흡착면(W)에 대한 흡반(10)의 진공 흡착시 유동성이 심화되어 흡반(20)의 흡착 위치가 미세하게 가변되는 문제를 야기하게 되어 안정된 흡착력을 제공하는 데는 한계가 있을 수밖에 없다는 것이다.In more detail, when the Showa hardness of the adsorption layer 26 is higher than 10 to 15, the adhesion to the surface to be adsorbed is lowered, for example, the adsorption layer has a hard property to provide soft and soft adhesion. In contrast, when the Showa hardness is lower than 10 to 15, on the contrary, the softness and softness are strengthened, but the viscosity is too low, so that the fluidity during vacuum adsorption of the sucker 10 against the suction surface W is increased. This causes a problem that the adsorption position of the sucker 20 is minutely changed, so that there is no limit to providing a stable adsorption force.
한편, 본 발명에 따르면, 상기 흡착층(26)은 도 3에 표시한 바와 같이 1.5~2㎜ 두께(t) 범위 내에서 일체로 융착되도록 제조됨이 가장 바람직하다. 왜냐하면, 흡착 테스트 결과, 상기한 두께 보다 얇아지는 경우에는 요철이 심한 피 흡착면(W)에 대한 밀착성, 즉, 요철면(W2)에 파고 들어가는 정도가 약하기 때문에 견고한 밀착력의 제공이 불가능하게 되는 문제가 있다. 물론 상기한 두께보다 두껍게 융착되는 경우에는 특별히 제한될 필요는 없으나 엘라스토머 소재가 고가이어서 제조 단가의 상승 문제를 비롯하여 필요 이상으로 흡반의 전체 하중이나 부피가 커지게 되는 문제를 야기할 수 있기 때문에 권장할 만한 것은 아니다.Meanwhile, according to the present invention, the adsorption layer 26 is most preferably manufactured to be integrally fused within the range of 1.5-2 mm thickness t, as shown in FIG. 3. Because, as a result of the adsorption test, when the thickness becomes thinner than the above-mentioned thickness, the adhesion to the adsorption surface W, which is roughly uneven, that is, the degree of digging into the uneven surface W2 is weak, which makes it impossible to provide a firm adhesion force. There is. Of course, if the fusion is thicker than the above-mentioned thickness is not particularly limited, but because the elastomer material is expensive, it may cause problems such as the increase in manufacturing cost and the problem that the overall load or volume of the sucker becomes larger than necessary, it is recommended. It's not worth it.
그리고, 본 발명에 따르면, 흡착 조작용 판재(22)에 대하여 1,2차 사출 성형되는 조건은 작업 환경에 따라 달리할 수 있으나, 본 발명의 경우 피복층(24) 및 흡착층(26)의 사출 압력은 50~60㎏/㎠로 하고, 사출 시간은 30~40초, 사출 온도는 190~200℃ 정도의 조건에서 진행함이 가장 바람직하다.In addition, according to the present invention, the conditions for injection molding the first and second injection molding plates 22 may vary depending on the working environment. However, in the present invention, the injection of the coating layer 24 and the adsorption layer 26 is performed. The pressure is 50 to 60 kg / cm 2, the injection time is 30 to 40 seconds, the injection temperature is most preferably proceeded under the conditions of about 190 ~ 200 ℃.
본 발명에 따르면, 진공 흡착구(1)의 흡착층(26)으로는 동일한 소재의 분리편(26a)이 일체로 를 사출 성형되어 짐이 바람직하다. 이는 피 흡착면으로 부터 진공 흡착구(1)의 분리를 보다 간편 용이하게 위한 것이다.According to the present invention, as the adsorption layer 26 of the vacuum adsorption port 1, it is preferable that the separate pieces 26a of the same material are injection molded integrally. This is for easier and easier separation of the vacuum suction port 1 from the suction surface.
도 10 내지 도 12를 이용하여 본 발명에 따른 진공 흡착구를 이용하여 피 흡착면에 대한 흡착시 누름 캡의 가압 및 회전 조작에 따른 작동 상태를 살펴보기로 한다. Using the vacuum suction port according to the present invention with reference to Figure 10 to 12 will be described the operating state according to the pressure and rotation operation of the pressing cap when the suction on the suction surface.

먼저, 도 10 및 도 11을 참조하면, 진공 흡착구(1)의 흡반(20)을 피 흡착면(W)에 흡착시키고자 하는 경우, 코일 스프링(50)의 탄력 설치된 누름 캡(40)을 가압하여준다, 그러면, 누름 캡은 그 하단으로 연장 형성된 연결 지지관(42)이 흡반(20)의 돌출봉(21) 하면, 예컨대 흡착 조작용 판재(22)의 상면을 누르게 되고, 동시에 상기 연결 지지관(42)에 형성된 가이드 돌기(44)는 지지 캡(10)의 관통공(12) 외주면으로 대응 형성된 가이드 홈(14)을 따라 수직 하강하게 되며, 상기 연결 지지관(42)에 형성된 가이드 돌기(44)가 가이드 홈(14)을 완전히 벗어날 때까지 누름 캡(40)을 눌러 준다.First, referring to FIGS. 10 and 11, when the suction plate 20 of the vacuum suction port 1 is to be adsorbed on the suction surface W, the push cap 40 that is elastically installed in the coil spring 50 is removed. Pressurized, then, the pressing cap is pressed to the upper surface of the plate 22 for adsorption operation, for example, when the connecting support tube 42 extending to the lower end of the protrusion rod 21 of the sucker 20, for example, Guide protrusions 44 formed on the support tube 42 are vertically lowered along the guide grooves 14 corresponding to the outer circumferential surface of the through hole 12 of the support cap 10, and the guides formed on the connection support tube 42. Press the press cap 40 until the projection 44 completely exits the guide groove 14.
상기한 상태에서 누름 캡(40)을 도 12 및 도 13과 같이 일방 향으로 회전 조작하여 주면, 상기 누름 캡(40)의 가이드 돌기(44)는 지지 캡의 관통공 외주연으로 형성된 가이드 홈(14)을 벗어나 그 외 부분에 상호 걸림 조작되고, 상기한 누름 캡(40)의 하강 및 회전 동작을 통해 상기 흡반(20)의 흡착 조작용 판재(22)는 원반 상태, 도면상 중앙부가 오목한 상태에서 그 중앙면이 피 흡착면(W)에 수평 상태로 접하도록 눌려져 피 흡착면과의 사이 공간에 존재하는 공기를 외부로 강제 배출시키도록 한다. 그리고, 상기한 공기의 배출은 일시적으로 이루어지는 것이 아니라 누름 캡(40)의 하강 회전을 인위적으로 복귀시키지 않는 이상 지속적으로 이루어지게 되어 결국 피 흡착면과의 사이 공간의 공기는 거의 전부가 배출되어 지도록 흡반(20)의 흡착 조작용 판재(22)의 하면으로 일체 융착된 경도가 낮은 엘라스토머의 흡착층(26)이 피 흡착면에 밀착되어 지고, 상기한 상태에서 누름 캡(40)을 원상 복귀시켜 주면, 상기 코일 스프링(50)의 반력과 흡착 조작용 판재(22)의 탄성 복귀력에 의해 피 흡착면(W)으로 부터 멀어지는 방향으로 살짝 들려지게 되면서 진공 흡착되어 진다.12 and 13, the guide protrusion 44 of the press cap 40 is formed by the outer periphery of the through hole of the support cap. 14 and the other side is engaged with each other, the lowering and rotating operation of the pressing cap 40, the adsorption manipulation plate 22 of the sucker 20 is in a disc state, the center portion in the drawing concave state The center surface is pressed in contact with the surface to be adsorbed in a horizontal state to force the air existing in the space between the surfaces to be adsorbed to the outside. In addition, the air is not discharged temporarily, but is continuously made unless the lowering rotation of the pressing cap 40 is artificially performed, so that almost all air in the space between the suction surface is discharged. The adsorption layer 26 of the low hardness elastomer which is integrally fused to the lower surface of the adsorption operation plate 22 of the sucker 20 is brought into close contact with the adsorption surface, and the press cap 40 is returned to its original state in the above state. The main surface is vacuum-adsorbed while being slightly lifted away from the surface to be adsorbed by the reaction force of the coil spring 50 and the elastic return force of the plate 22 for adsorption operation.
따라서, 본 발명의 진공 흡착구(1)를 이용하여 피 흡착면(W)에 대한 진공 흡착시 누름 캡(40)의 하강 및 회전 동작을 통해 흡반의 흡착층(26)이 피 흡착면(W)에 대해 수평적으로 눌려지면서 피 흡착면(W)사이 공간에 존재하는 공기가 외부로 전량 배출된 상태에서 상기 누름 캡(40)의 복귀 동작을 통해 상기 흡반(20)의 흡착층(26)이 피 흡착면에 대해 밀착되면서 강한 진공 흡착이 이루어지기 때문에 피 흡착면의 평탄 정도에 관계없이 항상 강한 진공 흡착 및 유지가 가능하게 된다.Therefore, by using the vacuum suction port 1 of the present invention, the suction layer 26 of the sucker is absorbed by the suction surface W through the lowering and rotating operation of the pressing cap 40 during the vacuum suction of the suction surface W. ), The adsorption layer 26 of the sucker 20 through the return operation of the pressing cap 40 in a state in which the air present in the space between the suction surfaces W is entirely discharged to the outside. Since strong vacuum adsorption is performed while being in close contact with the surface to be adsorbed, strong vacuum adsorption and maintenance is possible at all times regardless of the degree of flatness of the surface to be adsorbed.

도 14a 및 도 14b는 본 발명에 따른 진공 흡착구(1)가 매끄러운 면(W1)을 갖는 피 흡착면(W)에 가압되기 전 후의 상태를 보인 측 단면도이고, 도 15a 및 도 15b는 본 발명에 따른 진공 흡착구(1)가 요철면(W2)을 갖는 피 흡착면(W)에 각각 부착되기 전 후의 상태를 보인 측 단면도이다.14A and 14B are side cross-sectional views showing a state before and after the vacuum suction port 1 according to the present invention is pressed to the suction surface W having a smooth surface W1, and FIGS. 15A and 15B show the present invention. Is a side sectional view showing a state before and after the vacuum suction port 1 according to the present invention is attached to the suction surface W having the uneven surface W2, respectively.
이를 상술하면, 도 14a 및 도 14b와 같이 누름 캡(40)을 가압 및 해제하는 것에 의해 진공 흡착구(1)의 흡착층(26)은 유리면과 같은 매끈한 면(W1)을 갖는 피 흡착면(W)에 대한 진공 흡착이 가능할 뿐 아니라 특히, 도 15a 및 도 15b와 같이 요철 면(W2) 형태의 피 흡착면(W)이라 하더라도 강한 진공 흡착력을 제공하는 것이 가능하게 되는 것으로서, 진공 흡착구(1)의 흡반(20)이 폴리프로필렌이나 복합 폴리프로필렌으로 사출 제작되는 흡착 조작용 판재(22)의 상 하면으로 경도가 다른 엘라스트머를 이용하여 피복층(24) 및 흡착층(26)이 순차적으로 사출 융착되어져 있고, 흡착층(26)의 쇼와경도가 10~15 정도인 엘라스토머를 이용하여 1.5~2㎜ 두께로 성형됨에 따라 피 흡착면(W)의 평탄 정도, 예컨대 매끄러운 면(W1)을 갖는 벽이나, 유리 또는 타일 등을 비롯하여 차량의 데시보드 등 요철면(W2)으로 이루어진 피 흡착면(W)의 평탄 정도에 관계없이 포괄적으로 사용하는 것이 가능할 뿐 아니라 특히 요철면(W2)에 대한 진공 흡착시 흡착층(26)의 엘라스토머가 피 흡착면의 요철에 깊이 파고 들어가는 상태로 진공 흡착이 이루어지기 때문에 항상 견고한 밀착성을 제공하게 되어 장시간 사용하더라도 떨어지는 문제를 전혀 야기하지 않게 된다. 그리고, 흡반을 구성하는 흡착 조작용 판재(22)나 피복층(24) 및 흡착층(26)이 동일한 물성을 갖는 소재를 이용하여 사출 성형됨에 따라 이들 부재간의 층 분리 현상이 발생되지 않고, 또 진공 흡착구(1)의 사용 도중 흡착층(26)에 구멍 등이 형성되더라도 공기의 유입에 따른 진공 흡착력이 저하되는 등의 문제가 전혀 발생되지 않게 되는 것이다.Specifically, by pressing and releasing the press cap 40 as shown in FIGS. 14A and 14B, the adsorption layer 26 of the vacuum adsorption port 1 has an adsorption surface having a smooth surface W1 such as a glass surface ( In addition to being capable of vacuum adsorption to W), in particular, even in the case of the suction surface W in the form of the uneven surface W2 as shown in FIGS. 15A and 15B, it is possible to provide a strong vacuum suction force. The coating layer 24 and the adsorption layer 26 are sequentially formed by using an elastomer of different hardness to the upper and lower surfaces of the suction plate 20 for adsorption operation plate 22 produced by injection into polypropylene or composite polypropylene. And the flatness of the surface to be adsorbed (W1), for example, is smoothed by injection-fusion welding and is molded to 1.5 to 2 mm thickness using an elastomer having a Showa hardness of about 10 to 15 of the adsorption layer 26. Of vehicles, including walls, glass or tiles It can be used comprehensively regardless of the degree of flatness of the surface to be adsorbed (W) made of the uneven surface (W2) such as a board, and in particular, the elastomer of the adsorption layer 26 during the vacuum adsorption to the uneven surface (W2) is adsorbed. Since vacuum adsorption is carried out deeply into the unevenness of the cotton, it always provides a firm adhesiveness and does not cause any problem of dropping even when used for a long time. Then, as the plate material 22, the coating layer 24, and the adsorption layer 26 constituting the sucker are injection-molded using a material having the same physical properties, layer separation between these members does not occur and vacuum is generated. Even if holes or the like are formed in the adsorption layer 26 during the use of the adsorption port 1, problems such as deterioration of vacuum adsorption force due to the inflow of air are not generated at all.
실험 결과, 본 발명에 따른 흡반(20)이 채용된 진공 흡착구(1)를 이용하여 피 흡착면의 평탄 정도에 따라 흡착 유지기간을 측정한 결과, 피 흡착면(W)이 유리면과 같이 매끄러운 면(W1)인 경우에는 최소 120일 이상 견고하게 유지되었고, 또 요철면(W2) 상태의 피 흡착면인 경우에도 최소 90일 이상 견고하게 유지되는 것으로 나타났다.As a result of the experiment, the adsorption holding period was measured according to the degree of flatness of the surface to be sucked using the vacuum suction port 1 employing the sucker 20 according to the present invention. In the case of the surface (W1), it was firmly maintained for at least 120 days, and also in the case of the suction surface of the uneven surface (W2), it was firmly maintained for at least 90 days.
반대로, 종래 폴리염화비닐(PVC)이나 실리콘 소재 등으로 이루어진 흡반의 경우에는 본 발명에 따른 흡반과 동일한 조건하에서 실험한 결과 매끄러운 면의 경우 최대 60일을 넘지 못하였고, 요철면의 경우에는 최대 30일을 넘기지 못하고 떨어지는 것으로 나타났다. 더욱이 종래 흡반의 경우 온도 변화에 민감한 점을 감안하면, 아마도 상기한 측정일 보다 현저하게 낮은 유지 기간이 나올 수밖에 없음은 분명하다 할 것이다.On the contrary, in the case of a sucker made of conventional polyvinyl chloride (PVC) or a silicone material, the test was conducted under the same conditions as the sucker according to the present invention. It seemed to fall over and over. Furthermore, in view of the sensitivity to temperature changes in the case of conventional suckers, it will be clear that a remarkably lower holding period than the above-mentioned measurement day is inevitable.
따라서, 본 발명에 따른 흡반(20)을 이용한 진공 흡착구(1)는 종래 제시되고 있는 흡반의 경우와 비교하면 흡착층(26)을 경도가 낮은 엘라스토머를 이용하여 사출성형함에 따른 흡착성 및 밀착성의 향상이 현저하게 상승 됨을 쉽게 알 수 있다고 하겠다.Therefore, the vacuum adsorption port 1 using the sucker 20 according to the present invention has the adsorption and adhesion properties of the adsorption layer 26 by injection molding using the elastomer having a low hardness as compared with the case of the sucker. It is easy to see that the improvement is significantly increased.
그리고, 본 발명의 경우, 흡착 조작용 판재(22)를 제외한 피복층(24) 및 흡착층(26)이 적어도 90℃~―40℃ 범위 내에서는 온도 변화에 영향을 받지 않는 엘라스토머로 사출 성형되었기 때문에 계절에 따른 온도 변화에도 전혀 지장을 받지 않으면 범용적으로 사용할 수 있다는 장점이 있다. 특히 이 부분은 종래 피복소재가 경도가 높고 온도에 민감한 폴리염화비닐(PVC) 소재로 피복된 흡반과 비교할 때 피 흡착면의 평탄 정도 및 온도 변화에 따라 사용이 제한되는 것과 현저하게 비교된다고 할 것이다.In addition, in the case of the present invention, since the coating layer 24 and the adsorption layer 26 except the adsorption operation plate 22 are injection molded from an elastomer that is not affected by temperature change within at least 90 ° C to -40 ° C, There is an advantage that it can be used universally if it does not interfere with the temperature change according to the season. In particular, this part will be remarkably compared to the conventional coating material is limited in use due to the degree of flatness and temperature change of the surface to be adsorbed, compared with the sucker coated with a high hardness and temperature sensitive polyvinyl chloride (PVC) material. .
한편, 본 발명에 따르면, 흡착층(26)으로는 피 흡착면(W)에 대한 흡반(20)의 분리시에는 이에 형성된 분리편(26a)을 잡고 상측으로 들어 올려주는 것에 의해 흡착층(26)과 피 흡착면(W) 사이로 공기가 유입됨에 따라 상기한 흡착층과 피 흡착면은 진공이 해제되고 동시에 흡착층은 진공 흡착력을 상실하게 된다. 그러므로 흡반의 제거나 이동 흡착이 간편 용이하게 이루어진다.On the other hand, according to the present invention, the adsorption layer (26) by holding the separation piece (26a) formed thereon at the time of separation of the sucker 20 to the adsorption surface (W) to the adsorption layer (26). As the air flows between the) and the adsorption surface (W), the vacuum is released between the adsorption layer and the adsorption surface, and at the same time, the adsorption layer loses the vacuum adsorption force. Therefore, the removal and removal of the sucker is made easy.
이상과 같이 본 발명의 진공 흡착구(1)에 따르면, 피 흡착면(W)에 설치된 진공 흡착구는 엘라스토머로 구성된 흡반(20)의 흡착층(26)에 의해 더욱 견고한 밀착성의 유지가 가능하게 되고, 또 피 흡착면의 편탄 정도나 온도 변화 등에 따른 영향을 전혀 받지 않고 반 영구적으로 사용 가능하게 된다.As described above, according to the vacuum suction port 1 of the present invention, the vacuum suction port provided on the suction surface W can be maintained more firmly by the adsorption layer 26 of the sucker 20 formed of an elastomer. In addition, it can be used semi-permanently without being influenced by the degree of kneading of the adsorption surface or temperature change.
본 발명에 따른 진공 흡착구(1)은 경도가 낮은 엘라스토머를 이용한 흡착층(26)이 일체로 구비되어 있기 때문에 가정이나, 사무실, 학교, 산업현장 등 어디서나 누구나가 쉽게 사용할 수 있고, 또 피 흡착면(W)의 평탄 정도나 계절의 온도 변화에 전혀 관계없이 범용적으로 사용할 수 있는 것이다.Since the vacuum suction port 1 according to the present invention is integrally provided with an adsorption layer 26 using an elastomer having low hardness, anyone can easily use it anywhere at home, office, school, industrial site, etc. Regardless of the degree of flatness of the surface (W) or seasonal temperature changes, it can be used universally.
