Description

Technical Field

[0001] This utility model relates to the field of gaskets, and in particular to a gasket and a bracket using the gasket. Background Technology

[0002] As we all know, with the continuous development of society, people are using stands more and more in their daily lives. For example, people use stands to support mobile phones or monitors. In order to facilitate the transportation and storage of the above-mentioned stands, some stands adopt a rotatable folding structure. Specifically, these stands include a support leg assembly, an intermediate connector, and a support assembly. The support leg assembly includes a first support leg, a second support leg, and a first rotating connecting shaft. The first rotating connecting shaft passes through the first support leg and the second support leg and is connected to the lower end of the intermediate connector. The support assembly is rotatably mounted on the upper end of the intermediate connector. The support assembly is used to support the workpiece. The first support leg and the second support leg can rotate relative to each other around the first rotating connecting shaft to open or close and overlap. The intermediate connector can drive the support assembly to swing upward or downward relative to the second support leg around the first rotating connecting shaft, thereby adjusting the position of the stand supporting the workpiece.

[0003] To better adjust the position of the intermediate connector as it swings upwards or downwards relative to the second support leg around the first rotating connecting shaft, existing brackets use a shim between the second support leg and the intermediate connector. The first rotating connecting shaft rotatably connects the second support leg and the intermediate connector, causing them to clamp the shim together. This increases the frictional damping between the second support leg and the intermediate connector, allowing the intermediate connector to maintain its position when it swings the support assembly around the first rotating connecting shaft relative to the second support leg. However, existing shims are generally sheet-like, resulting in low frictional damping between the shim and the second support leg, and also low frictional damping between the shim and the intermediate connector itself. When the support assembly supports a workpiece for an extended period, gravity causes the workpiece to press against the support assembly, causing the intermediate connector to rotate downwards relative to the shim, or vice versa. This prevents the bracket from providing sustained workpiece support and does not meet user requirements. Utility Model Content

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, a first aspect of this invention provides a gasket that can effectively increase the frictional damping between the gasket and the contacting component; a second aspect of this invention also provides a bracket using the aforementioned gasket, making it difficult for the two rotating parts of the bracket used to clamp the gasket to rotate relative to each other.

[0005] A gasket according to an embodiment of the present utility model includes a gasket body, a first protrusion is provided at one end of the gasket body, a first abutment surface is provided at the end of the first protrusion away from the gasket body, a second abutment surface is provided on the outer periphery of the first protrusion, and an installation hole is provided in the middle of the gasket body, the installation hole penetrating the gasket body and the first protrusion.

[0006] A gasket according to an embodiment of the present utility model has at least the following beneficial effects:

[0007] In this embodiment, the gasket has a first protrusion at one end of the gasket body, a first abutment surface at the end of the first protrusion away from the gasket body, and a second abutment surface on the outer periphery of the first protrusion. Therefore, when the gasket of this embodiment is applied between two rotating parts, one end of the gasket body abuts against one of the rotating parts, while the gasket body is pressed tightly against the other rotating part through the first abutment surface and the second abutment surface of the first protrusion at the other end. This greatly increases the contact area between the gasket body and the other rotating part, and greatly increases the frictional damping between the gasket body and the other rotating part. As a result, when the two rotating parts cooperate to clamp the gasket of this embodiment, it is not easy for the two rotating parts to rotate relative to each other.

[0008] In some embodiments of this utility model, a third abutting surface is provided at one end of the gasket body near the first boss, and the second abutting surface is located between the first abutting surface and the third abutting surface.

[0009] In some embodiments of this utility model, the first contact surface and the third contact surface are mutually parallel planes.

[0010] In some embodiments of this utility model, the second abutting surface is an inclined surface that is inclined to the first abutting surface.

[0011] In some embodiments of this utility model, the gasket body is a cylinder, and the first boss is a frustum disposed at one end of the gasket body, and the first boss is coaxially arranged with the gasket body.

[0012] In some embodiments of this utility model, a first snap-fit ​​structure is provided at the end of the gasket body away from the first boss.

[0013] In some embodiments of this utility model, the first snap-fit ​​structure includes one or more snap-fit ​​blocks, the snap-fit ​​blocks are disposed at the end of the gasket body away from the first boss, and the snap-fit ​​blocks are located on one side of the mounting hole.

[0014] In some embodiments of this utility model, the number of the card blocks is two, the two card blocks are arranged in a row, and the mounting hole is located between the two card blocks.

[0015] In some embodiments of this utility model, a second boss is provided at the end of the gasket body away from the first boss, a fourth abutment surface is provided at the end of the second boss away from the first boss, and a fifth abutment surface is provided on the outer periphery of the second boss.

[0016] A bracket according to an embodiment of the present invention includes a bracket body and the aforementioned gasket. The bracket body has a first rotating member, a second rotating member, and a rotating shaft. The first rotating member and the second rotating member are rotatably connected together by the rotating shaft. The gasket body is located between the first rotating member and the second rotating member, and the rotating shaft passes through the mounting hole of the gasket body. The end of the gasket body away from the first boss abuts against the first rotating member. The end face of the second rotating member facing the gasket body has an insert groove. The first boss is inserted into the insert groove. The first abutting surface abuts against the bottom wall of the insert groove, and the second abutting surface abuts against the inner side wall of the insert groove.

[0017] A support according to an embodiment of the present utility model has at least the following beneficial effects:

[0018] In this embodiment, a bracket has a gasket provided between a first rotating member and a second rotating member. The second rotating member has an insert groove on its end face facing the gasket body. When the first and second rotating members clamp the gasket body, the end of the gasket body away from the first boss abuts against the first rotating member. The first boss at the other end of the gasket body is inserted into the insert groove of the second rotating member. The first abutment abuts against the bottom wall of the insert groove, and the second abutment abuts against the inner side wall of the insert groove. This greatly increases the contact area between the gasket body and the second rotating member. Therefore, when the gasket body rotates relative to the second rotating member, the frictional damping between the gasket and the second rotating member is greatly increased. This allows the first and second rotating members of the bracket in this embodiment to remain unchanged when they rotate relative to each other to a certain position, and it is not easy for them to rotate relative to each other, thus better meeting the user's needs for adjusting the bracket.

[0019] In some embodiments of this utility model, a third abutment surface is provided at one end of the gasket body near the first boss. When the first boss is fitted into the fitting groove, the first abutment surface abuts against the bottom wall of the fitting groove, the second abutment surface abuts against the inner side wall of the fitting groove, and the third abutment surface abuts against the end face of the second rotating member facing the gasket body.

[0035] Reference Figures 1 to 9 and mainly refer to Figure 1 , Figure 2 , Figure 3 According to certain embodiments of the present invention, a gasket is sometimes simply referred to as a "gasket". A gasket includes a gasket body 100, one end of which is provided with a first protrusion 110. The first protrusion 110 extends along a direction away from the other end of the gasket body 100. A first abutment surface 111 is provided at the end of the first protrusion 110 away from the gasket body 100. A second abutment surface 112 is provided on the outer periphery of the first protrusion 110. A mounting hole 120 is provided in the middle of the gasket body 100, penetrating the gasket body 100 and the first protrusion 110.

[0036] In this embodiment, the gasket has a first protrusion 110 at one end of the gasket body 100, a first abutment surface 111 at the end of the first protrusion 110 away from the gasket body 100, and a second abutment surface 112 on the outer periphery of the first protrusion 110. Therefore, when the gasket of this embodiment is applied between two rotating parts, one end of the gasket body 100 abuts against one of the rotating parts, while the gasket body 100 is pressed tightly against the other rotating part through the first abutment surface 111 and the second abutment surface 112 of the first protrusion 110 at the other end. This greatly increases the contact area between the gasket body 100 and the other rotating part, thereby effectively increasing the frictional damping between the gasket body 100 and the other rotating part. As a result, when the two rotating parts cooperate to clamp the gasket of this embodiment, it is not easy for relative rotation to occur between the two rotating parts.

[0037] Reference Figures 1 to 3 In order to further increase the contact area between the end of the gasket body 100 with the first protrusion 110 and the abutting member, in some embodiments of the present invention, a third abutting surface 130 is provided at the end of the gasket body 100 near the first protrusion 110, and a second abutting surface 112 is located between the first abutting surface 111 and the third abutting surface 130. By adopting the above structure, when the end of the gasket body 100 with the first protrusion 110 abuts against the abutting member, the gasket body 100 can abut against the abutting member through the first abutting surface 111, the second abutting surface 112, and the third abutting surface 130, thereby further increasing the contact area between the end of the gasket body 100 with the first protrusion 110 and the abutting member.

[0038] In some embodiments of this utility model, the first abutting surface 111 and the third abutting surface 130 are mutually parallel planes, such as... Figure 1 As shown, the first boss 110 is located in the middle of the gasket body 100, and the third abutment surface 130 is arranged around the outer periphery of the first boss 110. By adopting the above structure, the production and processing of the gasket in this embodiment is facilitated, which helps to reduce production costs.

[0039] In some embodiments of this utility model, the second abutting surface 112 is an inclined surface that is inclined to the first abutting surface 111. One end of the second abutting surface 112 is connected to the first abutting surface 111, and the other end of the second abutting surface 112 is connected to the third abutting surface 130. By adopting the above structure, the surface area of ​​the second abutting surface 112 can be further increased.

[0040] In some embodiments of this utility model, the gasket body 100 is a cylinder, and the first boss 110 is a frustum disposed at one end of the gasket body 100, and the first boss 110 is coaxially arranged with the gasket body 100. By adopting the above structure, the structure of the gasket in this embodiment can be made more compact, easier to manufacture and process, and have lower production costs.

[0041] Reference Figures 1 to 9 In some embodiments of this utility model, a first snap-fit ​​structure is provided at the end of the gasket body 100 away from the first protrusion 110. In this embodiment, the gasket has a first snap-fit ​​structure and a first protrusion 110 correspondingly provided at both ends of the gasket body 100. Therefore, when the gasket of this embodiment is applied between two rotating parts, the gasket body 100 snaps into one of the rotating parts through the first snap-fit ​​structure at one end, so that the rotating part and the gasket body 100 are connected to form a whole without relative rotation. At the same time, the gasket body 100 is pressed tightly against the other rotating part through the first abutment surface 111 and the second abutment surface 112 of the protrusion 110 at the other end, greatly increasing the contact area between the gasket body 100 and the other rotating part. This effectively increases the frictional damping between the gasket body 100 and the other rotating part, making it less likely for relative rotation to occur between the two rotating parts when they cooperate to clamp the gasket of this embodiment.

[0042] In some embodiments of this utility model, the first snap-fit ​​structure includes one or more snap-fit ​​blocks 140. The snap-fit ​​blocks 140 are disposed at the end of the gasket body 100 away from the first boss 110, and are located on one side of the mounting hole 120. By adopting the above structure, when the gasket of this embodiment is connected to other parts, the gasket body 100 is snapped and fixed to other parts by the snap-fit ​​blocks 140 at the end, making installation simpler and faster.

[0043] In some embodiments of this utility model, there are two locking blocks 140, arranged in a row, with the mounting hole 120 located between the two locking blocks 140. By adopting the above structure, the structure layout of the gasket can be made more reasonable and compact, and the gasket body 100 can be connected to other parts by the two locking blocks 140, making the connection between the gasket and other components more secure.

[0044] In some embodiments of this invention, there are multiple locking blocks 140, all of which are evenly arranged circumferentially around the mounting hole 120. By adopting the above structure, the gasket body 100 can be connected to other parts by multiple locking blocks 140, further enhancing the connection performance between the gasket and other components.

[0045] In some embodiments of this utility model, the gasket body 100, the first snap-fit ​​structure, and the first boss 110 are integral structures. Specifically, the gasket body 100, the first snap-fit ​​structure, and the first boss 110 are integrally injection molded from nylon or plastic, thereby making the gasket of this embodiment have lower production costs and more convenient production.

[0046] Reference Figures 1 to 9 In some embodiments of this utility model, a second boss is provided at the end of the gasket body 100 away from the first boss 110, a fourth abutment surface is provided at the end of the second boss away from the first boss 110, and a fifth abutment surface is provided on the outer periphery of the second boss. Because the gasket of this embodiment has a first boss 110 and a second boss correspondingly provided at both ends of the gasket body 100, when the gasket of this embodiment is applied between two rotating parts, the first boss 110 at one end of the gasket body 100 is pressed tightly against one of the rotating parts through the first abutment surface 111 and the second abutment surface 112, and the second boss at the other end of the gasket body 100 is pressed tightly against the other rotating part through the fourth and fifth abutment surfaces. This greatly increases the contact area between the gasket body 100 and the two rotating parts, effectively increasing the frictional damping between the gasket body 100 and the two rotating parts. Consequently, when the two rotating parts cooperate to clamp the gasket of this embodiment, relative rotation between the two rotating parts is less likely to occur.

[0047] Reference Figures 1 to 9A bracket according to certain embodiments of the present invention includes a bracket body 200 and the aforementioned gasket. The bracket body 200 has a first rotating member 210, a second rotating member 220, and a rotating shaft 230. The first rotating member 210 and the second rotating member 220 are rotatably connected together by the rotating shaft 230. The gasket body 100 is located between the first rotating member 210 and the second rotating member 220, and the rotating shaft 230 passes through the mounting hole 120 of the gasket body 100. The first rotating member 210 has a second snap-fit ​​structure 211 on its end face facing the gasket body 100. In this embodiment, one end of the gasket body 100 is provided with the first snap-fit ​​structure, and the other end of the gasket body 100 is provided with a first boss 110. The first snap-fit ​​structure at the end of the gasket body 100 engages with the second snap-fit ​​structure 211. In this embodiment, the second snap-fit ​​structure 211 is a snap-fit ​​groove formed on the end face of the first rotating member 210 facing the gasket body 100. During installation, the first snap-fit ​​structure at the end of the gasket body 100 can be inserted into the snap-fit ​​groove on the end face of the first rotating member 210. Through the engagement of the first snap-fit ​​structure and the snap-fit ​​groove, the connection between the gasket body 100 and the first rotating member 210 is achieved. The end face of the second rotating member 220 facing the gasket body 100 has an insert groove 221. The first boss 110 is embedded in the insert groove 221. The first abutment surface 111 abuts against the bottom wall of the insert groove 221, and the second abutment surface 112 abuts against the inner side wall of the insert groove 221.

[0048] In this embodiment, a bracket has a gasket provided between a first rotating member 210 and a second rotating member 220. The first rotating member 210 has a second snap-fit ​​structure 211 on its end face facing the gasket body 100, and the second rotating member 220 has an insert groove 221 on its end face facing the gasket body 100. The first snap-fit ​​structure at one end of the gasket body 100 engages with the second snap-fit ​​structure 211, thus fixing the gasket body 100 to the first rotating member 210. When the first rotating member 210 and the second rotating member 220 clamp the gasket body 100, the first protrusion 110 at the other end of the gasket body 100 is embedded... The first abutting surface 111 abuts against the bottom wall of the mounting groove 221, and the second abutting surface 112 abuts against the inner side wall of the mounting groove 221, thereby greatly increasing the contact area between the gasket body 100 and the second rotating member 220. Therefore, when the gasket body 100 rotates relative to the second rotating member 220, the frictional damping between the gasket and the second rotating member 220 is greatly increased. This allows the first rotating member 210 and the second rotating member 220 of the bracket in this embodiment to remain unchanged when they rotate relative to each other to a certain position, and it is not easy for them to rotate relative to each other, thus better meeting the user's needs for adjusting the bracket.

[0049] In some embodiments of this utility model, a third abutment surface 130 is provided at one end of the gasket body 100 near the first protrusion 110. When the first protrusion 110 is fitted into the fitting groove 221, the first abutment surface 111 abuts against the bottom wall of the fitting groove 221, the second abutment surface 112 abuts against the inner side wall of the fitting groove 221, and the third abutment surface 130 abuts against the end face of the second rotating member 220 facing the gasket body 100. By adopting the above structure, the gasket body 100 can abut against the second rotating member 220 through the first abutment surface 111, the second abutment surface 112, and the third abutment surface 130, thereby further increasing the contact area between the gasket body 100 and the second rotating member 220. Therefore, the frictional damping between the gasket and the second rotating member 220 can be further increased, making it less likely for the first rotating member 210 and the second rotating member 220 of the bracket in this embodiment to rotate relative to each other to a certain position, thus better meeting the user's need to keep the bracket fixed.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
