Description

本発明は弁体構造に関し、特に、被作用物の通孔を正確に隙間無く密封することができるとともに、被作用物の通孔の密封を開放して被作用物内の対象物をスムーズに排出することができ、しかも、取り外ししやすく、安全性・安定性も兼ね備えた牽引式弁体構造に関する。 The present invention relates to a valve body structure, and in particular, can accurately seal a through hole of an actuated object without gaps, and smoothly opens an object in the actuated object by opening the seal of the through hole of the actuated object. The present invention relates to a traction valve body structure that can be discharged, is easy to remove, and has both safety and stability.

弁体は、その作用により通孔を自由に密封したり解放したりすることができる。そのため、頻繁に各種製品に応用されており、収納空間内における流体や固体等の対象物の出入りを制御するのに便利である。 The valve body can freely seal and release the through hole by its action. Therefore, it is frequently applied to various products, and is convenient for controlling the entry and exit of objects such as fluids and solids in the storage space.

既存の弁体構造は、例えば、通孔の部分に金属体を設け、該金属体を弁棒で押し、金属体で通孔を密封したり開放したりすることにより流体や固体が該通孔から出入りするのを制御し、弁体の作用を達成する。しかしながら、金属体、弁棒によって構成するこの種の弁体構造は、少なくとも下記のような欠点がある。 In the existing valve body structure, for example, a metal body is provided in the through hole portion, the metal body is pushed with a valve rod, and the through hole is sealed or opened with the metal body so that fluid or solid is passed through the through hole. Controls the entry and exit of the valve and achieves the action of the valve body. However, this type of valve body structure composed of a metal body and a valve stem has at least the following drawbacks.

１、金属体と弁棒は連結されておらず、しかも他の位置決め構造によって位置決めされているわけでもないため、該金属体は安定せずランダムに動いてしまい、素早く正確に通孔を塞ぐことが難しく、該通孔部分から対象物が漏洩してしまう可能性がある。 1. Since the metal body and the valve stem are not connected and are not positioned by another positioning structure, the metal body moves randomly without being stable, and closes the through hole quickly and accurately. Is difficult, and there is a possibility that the object leaks from the through-hole portion.

２、金属体は自身の重さのみで通孔を密封し、金属体の下方には何の牽引力も働かないため、金属体の重量が充分でないと、通孔部分から対象物が漏洩してしまう。 2. The metal body seals the through hole only with its own weight, and no traction force acts below the metal body, so if the weight of the metal body is not enough, the object will leak from the through hole part. End up.

３、通孔を開放させるため弁棒で金属体を押す時、金属体と弁棒は連結されていないため、金属体をうまく動かすことができずに金属体がずれて通孔の一部分を塞いでしまい、対象物が通孔からスムーズに流出できなくなる可能性がある。 3. When pushing the metal body with the valve stem to open the through hole, the metal body and the valve stem are not connected, so the metal body cannot move well and the metal body is displaced and blocks a part of the through hole Therefore, there is a possibility that the object cannot smoothly flow out of the through hole.

４、弁棒は一般的に外径が大きい物体上に設けられるが、該物体は何かの装置で被覆されるわけでも隔離されるわけでもないため、使用者が不注意により物体に触れてしまい、それにより弁棒で金属体が押され、金属体がずれて通孔を密封できずに対象物が漏洩してしまう現象が頻繁に生じる。 4. The valve stem is generally provided on an object with a large outer diameter. However, since the object is not covered or isolated by any device, the user may inadvertently touch the object. As a result, the metal body is pushed by the valve rod, and the metal body is displaced, and the phenomenon that the object leaks without being able to seal the through hole frequently occurs.

弁体構造においては、通孔を正確に隙間無く密封することができるとともに、通孔を簡単に開放することができ、しかも、取り外しがしやすく、安定性・安全性を兼ね備えた構造を設計することが重要である。 In the valve body structure, the through-hole can be accurately sealed without gaps, and the through-hole can be easily opened, and it is easy to remove, and a structure with stability and safety is designed. This is very important.

本発明の目的は、被作用物の通孔を正確に隙間無く密封することができるとともに、被作用物の通孔の密封を開放して被作用物内の対象物をスムーズに排出することができ、しかも、取り外ししやすく、安全性・安定性も兼ね備えた牽引式弁体構造を提供することにある。 An object of the present invention is to accurately seal the through-hole of the workpiece without gaps, and to smoothly discharge the object in the workpiece by opening the seal of the through-hole of the workpiece. Another object of the present invention is to provide a traction valve body structure that can be easily removed and has both safety and stability.

そこで、この本発明による牽引式弁体構造は、収納空間を具え、底部には通孔が穿設される被作用物と、収納空間に設けられる作用体と、被作用物の下方に上下移動自在に設けられ、少なくとも一つの透孔を有する牽引体と、によって構成され、作用体には連結部を設けるとともに、牽引体には被連結部を設けて該連結部と該被連結部を連結し、牽引体は、重力の作用により自身の重さで下に向かって移動すると同時に作用体を牽引して下に移動させ通孔を隙間無く密封し、また、牽引体は、押し上げる力を受けた時は作用体を牽引して上に移動させ通孔を開放し、被作用物下方の周縁は延伸して直径が牽引体より大きい突縁部を形成するように構成する。 Therefore, the towed valve body structure according to the present invention has a storage space, an actuated body having a through hole in the bottom, an actuating body provided in the stowage space, and a vertical movement below the actuated object. The traction body is provided freely and has at least one through hole. The working body is provided with a connecting portion, and the traction body is provided with a connected portion to connect the connecting portion and the connected portion. The traction body moves downward under its own weight by the action of gravity, and at the same time pulls the action body and moves it down to seal the through hole without any gaps. In this case, the working body is pulled and moved upward to open the through hole, and the peripheral edge below the work piece is stretched to form a protruding edge portion having a diameter larger than that of the pulling body.

この本発明による牽引式弁体構造は、被作用物の通孔を正確に隙間無く密封することができるとともに、被作用物の通孔の密封を開放して被作用物内の対象物をスムーズに排出することができるため、各種製品に広く応用することができ、利便性が得られる。 The towed valve body structure according to the present invention can accurately seal the through-hole of the workpiece without gaps, and can smoothly seal the target in the workpiece by opening the seal of the through-hole of the workpiece. Therefore, it can be widely applied to various products, and convenience is obtained.

さらに、この本発明による牽引式弁体構造は、設置した時に傾かないため安定性が高く、外部の接触から保護されるため安全性も高く、しかも取り外しがしやすいという利点を有する。 Furthermore, this towed valve body structure according to the present invention has the advantages of high stability because it does not tilt when installed, high safety because it is protected from external contact, and easy removal.

図１から図４に示すように、本発明は、被作用物１０、被作用物１０内に設けられた作用体２０、及び被作用物１０下方に設けられた牽引体３０によって構成する。 As shown in FIGS. 1 to 4, the present invention is configured by an object 10, an action body 20 provided in the action object 10, and a traction body 30 provided below the action object 10.

被作用物１０には収納空間１１を設け、流体、固体、又は粉末体等の対象物を装入することができる。被作用物１０内側の底部には通孔１２を穿設し、該通孔１２周縁には環状の突部１２１を設ける。被作用物１０内側の底部は所定の斜度を有し対象物を効果的に通孔１２へと誘導する。通孔１２には、弾性をもつ材料によってなり且つ穿孔１３１が穿設されたブッシング１３を設ける。穿孔１３１上方の周縁には、密着壁１３２と、密着壁１３２と隣接する溝部１３３を設ける。密着壁１３２は弾性変形力をもち、作用体２０と密着する。ブッシング１３の所定の箇所に係合溝１３４、係合リング１３５を設け、係合溝１３４、係合リング１３５と突部１２１を係合することによってブッシング１３は通孔１２に緊合される。被作用物１０下方の周縁は、延伸して直径が牽引体３０より大きい突縁部１４を形成し、突縁部１４は牽引体３０を被覆するため、牽引体３０は外部の接触から保護され安全性が向上する。突縁部１４には複数の支持体１４１を設けることで、被作用物１０は平面に設置された時に傾かなくなり安定性が向上する。被作用物１０下方には支持部１５を設け、支持部１５には複数のスライド溝１５１を設ける。 The object 10 is provided with a storage space 11 and can be filled with an object such as a fluid, a solid, or a powder. A through hole 12 is formed in the bottom of the inside of the workpiece 10, and an annular protrusion 121 is provided on the periphery of the through hole 12. The bottom of the inner side of the workpiece 10 has a predetermined inclination and effectively guides the object to the through hole 12. The through hole 12 is provided with a bushing 13 made of an elastic material and having a perforation 131 formed therein. A close-contact wall 132 and a groove 133 adjacent to the close-contact wall 132 are provided on the peripheral edge above the perforation 131. The contact wall 132 has an elastic deformation force and is in close contact with the action body 20. An engagement groove 134 and an engagement ring 135 are provided at predetermined locations of the bushing 13, and the bushing 13 is fastened to the through hole 12 by engaging the engagement groove 134, the engagement ring 135 and the protrusion 121. The peripheral edge below the workpiece 10 extends to form a protruding edge 14 having a diameter larger than that of the pulling body 30, and the protruding edge 14 covers the pulling body 30, so that the pulling body 30 is protected from external contact. Safety is improved. By providing a plurality of supports 141 on the projecting edge 14, the workpiece 10 does not tilt when installed on a flat surface, and stability is improved. A support portion 15 is provided below the workpiece 10, and a plurality of slide grooves 151 are provided in the support portion 15.

作用体２０はゴムなどの弾性を具える材料によってなり、作用体２０には連結部２１（本実施例においては孔状である）を設けることで、ブッシング１３の穿孔１３１を密封することができ、それにより、被作用物１０の通孔１２も密封され対象物が漏洩しなくなる。当然、本発明は、ブッシング１３を設置しなくてもよく、作用体２０で通孔１２を直接密封することもできる。 The action body 20 is made of a material having elasticity such as rubber, and the action body 20 is provided with a connecting portion 21 (in this embodiment, a hole shape), so that the perforations 131 of the bushing 13 can be sealed. Thereby, the through-hole 12 of the workpiece 10 is also sealed, and the object does not leak. Naturally, in the present invention, the bushing 13 may not be installed, and the through hole 12 may be directly sealed by the action body 20.

牽引体３０には、複数のリブ体３２、複数の透孔３３、被連結部３４を有する台座体３１と、台座体３１下方に位置する延長部３５を設ける。該台座体３１周縁には、スライド溝１５１に対応する複数の係合柱３６を設ける。係合柱３６は、スライド溝１５１に係入させることでスライド溝１５１から外れなくなるとともにスライド溝１５１内を上下に移動させることができ、それに連動して、牽引体３０も被作用物１０下方で上下に移動する。透孔３３は、対象物を下に通過させる。被連結部３４は柱状であり、穿孔１３１に嵌入された作用体２０の連結部２１と連結する。この被連結部３４、連結部２１の連結構造によって、牽引体３０、作用体２０は取り外しがしやすくなる。また、その連結箇所に粘性をもつ物質を塗布することで連結力を向上させることができる。被連結部３４には係止部３４０を設け、嵌入された作用体２０は係止部３４０で係止する。リブ体３２の中央の交差箇所の底部には錐状部３２１を設ける。牽引体３０が上に移動する時、作用体２０も連動して上に移動し穿孔１３１の位置から分離し、穿孔１３１の密封状態が解除される。 The traction body 30 is provided with a pedestal body 31 having a plurality of rib bodies 32, a plurality of through holes 33, and a connected portion 34, and an extension portion 35 positioned below the pedestal body 31. A plurality of engaging columns 36 corresponding to the slide grooves 151 are provided on the periphery of the base body 31. The engaging column 36 is engaged with the slide groove 151 so that it cannot be detached from the slide groove 151 and can be moved up and down in the slide groove 151. Move up and down. The through-hole 33 allows the object to pass down. The connected portion 34 has a columnar shape and is connected to the connecting portion 21 of the acting body 20 fitted in the perforation 131. Due to the coupling structure of the coupled portion 34 and the coupling portion 21, the traction body 30 and the action body 20 can be easily removed. Moreover, a connection force can be improved by apply | coating the viscous substance to the connection location. The connected portion 34 is provided with a locking portion 340, and the inserted action body 20 is locked by the locking portion 340. A conical portion 321 is provided at the bottom of the central intersection of the rib bodies 32. When the towing body 30 moves up, the action body 20 also moves up in conjunction with it and separates from the position of the perforation 131, and the sealed state of the perforation 131 is released.

図４に示すように、被作用体１０は平面に置いて使用することができる。この時、重力の作用により牽引体３０は自身の重さによって下に移動し、作用体２０は牽引体３０に牽引されて下方に移動し穿孔１３１を隙間無く密封するため、被作用物１０内の対象物が漏洩することがなくなる。 As shown in FIG. 4, the object 10 can be used by being placed on a flat surface. At this time, the pulling body 30 is moved downward by its own weight due to the action of gravity, and the action body 20 is pulled by the pulling body 30 and moves downward to seal the perforation 131 without any gap. The target object will not leak.

また、ブッシング１３の密着壁１３２は、作用体２０が自身の重力により下方に移動しようとすることで生じる外力を受けた時、その外力に抵抗し内側へ縮もうとする応力が生じ、それにより作用体２０の表面と密着して漏洩防止効果が更に強化される。 Further, when the acting body 20 receives an external force generated by the action body 20 trying to move downward due to its own gravity, the close contact wall 132 of the bushing 13 generates a stress that resists the external force and tends to shrink inward. Adhering to the surface of the action body 20 further enhances the leakage prevention effect.

図５に示すように、牽引体３０が下方から上に向かって押し上げる力を受ける時（例えば、手で牽引体３０を引き上げた時）、牽引体３０と被連結部３４は同時に上に向かって移動するとともに、作用体２０もそれに連動して上に向かって移動して穿孔１３１から分離し、それにより穿孔１３１が開放され、被作用物１０内の対象物は穿孔１３１、透孔３３を通って排出される。また、開放された穿孔１３１は作用体２０と全く接触していないため、穿孔１３１は完全な開放状態になり、対象物をスムーズに排出させることができる。 As shown in FIG. 5, when the pulling body 30 receives a force that pushes it upward from below (for example, when the pulling body 30 is pulled up by hand), the pulling body 30 and the connected portion 34 simultaneously move upward. At the same time, the action body 20 also moves upward in conjunction with it and separates from the perforation 131, thereby opening the perforation 131, and the object in the object 10 passes through the perforation 131 and the through-hole 33. Discharged. Further, since the opened perforations 131 are not in contact with the action body 20 at all, the perforations 131 are completely opened, and the object can be discharged smoothly.

又、錐状部３２１は、対象物を効果的に中央に誘導して排出させることができ、対象物が牽引体３０に残留しなくなる。 Further, the conical portion 321 can effectively guide and discharge the object to the center, and the object does not remain on the pulling body 30.

図６に示すように、被作用物１０内には網状の阻止部材４０を設け、対象物の内、大きめの物体や不必要な物が穿孔１３１に入り込むのを阻止し、穿孔１３１が詰まるのを防ぐことができる。 As shown in FIG. 6, a net-like blocking member 40 is provided in the object 10 to prevent large objects or unnecessary objects from entering the perforations 131, and the perforations 131 are clogged. Can be prevented.
