The inner protruding portion is located at the inner wall and protrudes toward the inserted space. The outer depressed portion is located at the outer wall and provides a space for the inner protruding portion to be deformed radially and outwardly. Therefore, with the space that the outer depressed portion provides, the inner protruding portion can deform after being pushed by the rotary shaft, which can provide contacting force between the O-shaped elastic ring and the rotary shaft and decrease the rubbing attrition. Therefore, the using life time can be increased.

Description

O型彈性環及盒體結構O-shaped elastic ring and box structure

本發明是有關一種彈性環及盒體結構，且特別是用於一種掀蓋式盒體的O型彈性環及盒體結構。The present invention relates to an elastic ring and a box structure, and in particular to an O-shaped elastic ring and a box structure for a flip-top box.

掀蓋式盒體具有底座及上蓋，透過實心銷與彈性環可將底座與上蓋連接，而實心銷是穿設於彈性環內。當上蓋打開時，彈性環受實心銷摩擦擠壓，而能提供阻力讓上蓋停於任何角度。然而，彈性環容易因摩擦而磨耗，故隨著開關的次數增加，上蓋的止停效果會慢慢減弱。The flip-top box has a base and an upper cover. The base and the upper cover can be connected through a solid pin and an elastic ring, and the solid pin is inserted into the elastic ring. When the upper cover is opened, the elastic ring is frictionally squeezed by the solid pin and provides resistance to allow the upper cover to stop at any angle. However, the elastic ring is easily worn due to friction, so as the number of switches increases, the stopping effect of the upper cover will gradually weaken.

有鑑於此，如何改善上述問題以增加彈性環及掀蓋式盒體的使用壽命，遂成相關業者極欲解決的問題。In view of this, how to improve the above problems to increase the service life of the elastic ring and the flip-top box has become a problem that relevant industry players are eager to solve.

請參閱第1圖、第2圖及第3圖，其中第1圖繪示依照本發明第1實施例之一種O型彈性環100的立體示意圖，第2圖繪示第1圖第1實施例之O型彈性環100容設於一孔洞H1的側視剖面示意圖，第3圖繪示第1圖第1實施例之O型彈性環100容設於孔洞H1內且供一轉軸P1插設的側視剖面示意圖。O型彈性環100用以設置於孔洞H1內並配合轉軸P1，O型彈性環100包含一內壁110、一外壁120、至少一內凸部130以及至少一外凹部140。內壁110界定出一穿設空間S1供轉軸P1穿設，外壁120相反於內壁110。內凸部130位於內壁110且朝穿設空間S1凸出，外凹部140位於外壁120且提供內凸部130徑向朝外變形的空間。Please refer to Figures 1, 2 and 3. Figure 1 shows a schematic three-dimensional view of an O-shaped elastic ring 100 according to the first embodiment of the present invention. Figure 2 shows the first embodiment of Figure 1. A schematic side cross-sectional view of the O-shaped elastic ring 100 accommodated in a hole H1. Figure 3 shows the O-shaped elastic ring 100 accommodated in the hole H1 of the first embodiment in Figure 1 and for a rotating shaft P1 to be inserted. Schematic side view of section. The O-shaped elastic ring 100 is used to be disposed in the hole H1 and cooperate with the rotating shaft P1. The O-shaped elastic ring 100 includes an inner wall 110, an outer wall 120, at least one inner convex part 130 and at least one outer concave part 140. The inner wall 110 defines a penetration space S1 for the rotation shaft P1 to pass through, and the outer wall 120 is opposite to the inner wall 110 . The inner protruding portion 130 is located on the inner wall 110 and protrudes toward the penetration space S1. The outer concave portion 140 is located on the outer wall 120 and provides a space for the inner protruding portion 130 to deform radially outward.

藉此，透過外凹部140提供變形的空間，內凸部130受轉軸P1推擠後具有足夠空間變形，並可在提供轉軸P1接觸力時降低摩擦損耗，而能增加使用壽命。後面將更詳細地說明O型彈性環100的細節。Thereby, the outer concave portion 140 provides a space for deformation, and the inner convex portion 130 has enough space to deform after being pushed by the rotating shaft P1, and can reduce friction loss when providing the contact force of the rotating shaft P1, thereby increasing the service life. The details of the O-ring 100 will be described in more detail later.

O型彈性環100是由彈性材質製成之一件式結構，故O型彈性環100受壓後可變形。如第1圖所示，內凸部130的數量可為複數，且內凸部130可間隔設置於內壁110。外凹部140的數量亦為複數，外凹部140間隔設置於外壁120，且各內凸部130至少部分對應各外凹部140。The O-shaped elastic ring 100 is a one-piece structure made of elastic material, so the O-shaped elastic ring 100 can be deformed under pressure. As shown in FIG. 1 , the number of the inner protrusions 130 may be plural, and the inner protrusions 130 may be spaced apart from the inner wall 110 . The number of the outer concave portions 140 is also plural. The outer concave portions 140 are arranged at intervals on the outer wall 120 , and each inner convex portion 130 at least partially corresponds to each outer concave portion 140 .

具體地，如第1圖及第2圖所示，內凸部130及外凹部140的數量可相同，內凸部130及外凹部140的數量均為五個，且內凸部130及外凹部140均呈弧狀。在O型彈性環100成形時，可透過內徑的變化及外徑的變化，一體形成五個內凸部130及五個外凹部140，內凸部130頂點所圍成之虛擬圓的直徑小於內壁110的直徑，外凹部140凹點所圍成之虛擬圓的直徑亦小於外壁120的直徑，且讓各內凸部130的中心線I1與各外凹部140的中心線I2共線，並通過O型彈性環100的圓心O1，而讓各內凸部130及各外凹部140完全對應。在其他實施例中，各內凸部的中心線與各外凹部的中心線可不共線，而較佳地彼此仍有部分區域對應，而能提供內凸部較佳之朝外變形空間。Specifically, as shown in Figures 1 and 2, the number of the inner convex portions 130 and the outer concave portions 140 can be the same, the number of the inner convex portions 130 and the outer concave portions 140 is five, and the inner convex portions 130 and the outer concave portions are 140 are all curved. When the O-shaped elastic ring 100 is formed, five inner convex portions 130 and five outer concave portions 140 can be integrally formed through changes in the inner diameter and outer diameter. The diameter of the virtual circle enclosed by the vertices of the inner convex portions 130 is less than The diameter of the inner wall 110 and the diameter of the virtual circle enclosed by the concave points of the outer concave portion 140 are also smaller than the diameter of the outer wall 120, and the center line I1 of each inner convex portion 130 and the center line I2 of each outer concave portion 140 are collinear, and Through the center O1 of the O-shaped elastic ring 100, each inner convex part 130 and each outer concave part 140 are completely corresponding. In other embodiments, the center line of each inner convex portion and the center line of each outer concave portion may not be collinear, but preferably still have partial regions corresponding to each other, thereby providing a better outward deformation space for the inner convex portions.

如第3圖所示，當O型彈性環100設置於孔洞H1內時，外壁120可抵頂於孔洞H1的孔壁，而轉軸P1***穿設空間S1時，會直接與內凸部130接觸，並擠壓內凸部130，內凸部130於徑向上產生變形。由於內凸部130的外側對應外凹部140，外凹部140與孔壁之間具有間隙，而能讓內凸部130有空間可以變形。As shown in Figure 3, when the O-shaped elastic ring 100 is disposed in the hole H1, the outer wall 120 can resist the hole wall of the hole H1, and when the rotating shaft P1 is inserted into the penetration space S1, it will directly contact the inner protrusion 130. , and squeezes the inner protruding portion 130, causing the inner protruding portion 130 to deform in the radial direction. Since the outer side of the inner convex part 130 corresponds to the outer concave part 140, there is a gap between the outer concave part 140 and the hole wall, which allows the inner convex part 130 to have space to deform.

請參閱第4圖及第5圖，其中第4圖繪示依照本發明第2實施例之一種盒體結構200的立體示意圖，第5圖繪示第4圖第2實施例之盒體結構200的***示意圖。盒體結構200包含一底座210、一上蓋220、至少一轉軸240以及至少一O型彈性環230。底座210包含至少一第一插接孔211，上蓋220蓋設於底座210且包含至少一第二插接孔221，第二插接孔221對應第一插接孔211。轉軸240插設於第一插接孔211及第二插接孔221，以連接底座210與上蓋220。Please refer to Figures 4 and 5. Figure 4 shows a schematic three-dimensional view of a box structure 200 according to the second embodiment of the present invention. Figure 5 shows the box structure 200 of the second embodiment of Figure 4. Explosion diagram. The box structure 200 includes a base 210, an upper cover 220, at least one rotating shaft 240 and at least one O-shaped elastic ring 230.

The inner wall defines a penetration space S1 for the rotating shaft 240 to penetrate, and the outer wall is opposite to the inner wall. The inner convex portion 231 is located on the inner wall and protrudes toward the penetration space S1. The outer concave portion 232 is located on the outer wall and corresponds to the inner convex portion 231. The outer concave portion 232 provides a space for the inner convex portion 231 to deform radially outward.

具體地，底座210可包含一容置空間供放置物件，上蓋220可相對底座210蓋上以封閉容置空間，或掀起以供拿取物件。第一插接孔211的數量、第二插接孔221的數量、轉軸240的數量及O型彈性環230的數量均為二，各O型彈性環230容設於各第二插接孔221。二第一插接孔211是間隔設置於底座210的上緣，且底座210更包含二凹槽212，各凹槽212與各第一插接孔211連通，上蓋220更包含二凸塊222，二凸塊222間隔設置於上蓋220的內緣，各凸塊222對應容設於各凹槽212，且各第二插接孔221貫穿各凸塊222。因此，在各轉軸240***各O型彈性環230及各第一插接孔211後，上蓋220即可連接底座210。Specifically, the base 210 may include an accommodating space for placing objects, and the upper cover 220 may be closed relative to the base 210 to close the accommodating space, or be lifted up for taking objects. The number of first insertion holes 211 , the number of second insertion holes 221 , the number of rotating shafts 240 and the number of O-shaped elastic rings 230 are all two, and each O-type elastic ring 230 is accommodated in each second insertion hole 221 . The two first plug holes 211 are spaced apart on the upper edge of the base 210, and the base 210 further includes two grooves 212. Each groove 212 is connected with each first plug hole 211. The upper cover 220 further includes two bumps 222. Two protrusions 222 are spaced apart from the inner edge of the upper cover 220 . Each protrusion 222 is correspondingly accommodated in each groove 212 , and each second insertion hole 221 penetrates each protrusion 222 . Therefore, after each rotating shaft 240 is inserted into each O-shaped elastic ring 230 and each first insertion hole 211, the upper cover 220 can be connected to the base 210.

O型彈性環230的結構和第1實施例之O型彈性環100相同，細節不再贅述。轉軸240可包含一頭部241、一環齒部242以及一平滑軸部243，頭部241外露於第一插接孔211，環齒部242連接頭部241且位於第一插接孔211內。平滑軸部243連接於環齒部242，且用以插設於O型彈性環230的穿設空間S1，並推擠O型彈性環230的各內凸部231，如此，可增加連接的穩定度。The structure of the O-shaped elastic ring 230 is the same as the O-shaped elastic ring 100 in the first embodiment, and the details will not be described again. The rotating shaft 240 may include a head portion 241 , a ring tooth portion 242 and a smooth shaft portion 243 . The head portion 241 is exposed in the first insertion hole 211 . The ring tooth portion 242 is connected to the head portion 241 and is located in the first insertion hole 211 . The smooth shaft portion 243 is connected to the ring tooth portion 242 and is used to be inserted into the insertion space S1 of the O-shaped elastic ring 230 and push each inner protrusion 231 of the O-shaped elastic ring 230, thus increasing the stability of the connection.

請參閱第6圖及第7圖，其中第6圖繪示第4圖第2實施例之盒體結構200的一側視剖面示意圖，第7圖繪示第4圖第2實施例之盒體結構200的另一側視剖面示意圖。透過O型彈性環230的結構，可提供轉軸240一定的接觸力，以形成阻力，藉以在上蓋220未受外力作用的情況下，維持其與底座210之間的位置關係。因此，上蓋220開啟或關閉的過程中，可相對底座210停止在任意旋轉角度的位置，例如第6圖的位置或第7圖的位置，且O型彈性環230在提供接觸力的同時仍有空間做相對變形，可大幅減低摩擦損耗並增長使用壽命，同時提供穩定的接觸力。Please refer to Figures 6 and 7. Figure 6 shows a schematic side cross-sectional view of the box structure 200 of the second embodiment of Figure 4, and Figure 7 shows the box of the second embodiment of Figure 4. Another schematic side cross-sectional view of structure 200 . Through the structure of the O-shaped elastic ring 230, a certain contact force can be provided to the rotating shaft 240 to form resistance, thereby maintaining the positional relationship between the upper cover 220 and the base 210 when no external force is applied. Therefore, during the opening or closing process, the upper cover 220 can be stopped at any rotation angle position relative to the base 210, such as the position in Figure 6 or the position in Figure 7, and the O-shaped elastic ring 230 still provides contact force while still maintaining the position. Relative deformation of space can significantly reduce friction loss and increase service life, while providing stable contact force.
