Description

Technical Field

[0001] This invention relates to the field of hardware technology, and more particularly to a hinge and door mounting structure. Background Technology

[0002] For doors that open and close by turning, they are typically connected to the door frame or wall via hinges. Some hinges provide damping for the door's rotation, cushioning the opening and closing process. This prevents the door from turning too quickly due to inertia, thus improving the user experience. However, the cushioning effect provided by hinges is often monotonous during the door's rotation, with poor cushioning at the end of the rotation. This can result in the door still moving relatively fast, increasing the risk of the door colliding with the door frame. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a hinge with multiple different cushioning effects, and the cushioning effect is higher at the end of the hinge's rotation process.

[0004] The present invention also proposes a door mounting structure including the above-mentioned hinge.

[0005] According to a first aspect of the present invention, a hinge includes: a main shaft; a first body; a first connecting rod connected to the first body; a second body; a second connecting rod connected to the second body, the first connecting rod and the second connecting rod being rotatably connected via the main shaft; a second abutting shaft parallel to the main shaft and connected to the second connecting rod; a second abutting block movably mounted on the second body, the second abutting block being movable relative to the second body along the axial direction of the second abutting shaft, the second abutting block being provided with a second inclined surface and a third inclined surface, the included angle between the second inclined surface and the second abutting shaft being a first included angle, the included angle between the third inclined surface and the second abutting shaft being a second included angle, the first included angle being greater than the second included angle, and both the first included angle and the second included angle being acute angles; an elastic member mounted on the second body, the two ends of the elastic member being connected to the second body and the second abutting block respectively; when the second body is rotatable relative to the first body and the second abutting shaft contacts the second inclined surface and the third inclined surface in sequence, the second abutting shaft moves laterally to drive the second abutting block to move, thereby causing the elastic member to contract.

[0006] According to the first aspect of the present invention, the hinge has at least the following beneficial effects: when the second abutting shaft abuts against the second or third inclined surface and moves laterally, it can push the second abutting block, thereby pushing the elastic element, which is compressed to provide cushioning. Compared to when the second abutting shaft abuts against the second inclined surface, when the second abutting shaft abuts against the third inclined surface and moves laterally, the lateral movement resistance of the second abutting shaft is greater, and the resistance when the second body rotates relative to the first body is greater. Thus, at the end of the process of the hinge rotating and being cushioned by the elastic element, the hinge's cushioning effect on the door is stronger, preventing the door from rotating too fast and colliding violently with the door frame.

[0007] According to some embodiments of the present invention, the hinge further includes: a first abutting shaft, parallel to the main shaft, and connected to the first connecting rod; a first abutting block, movably mounted on the first body, the first abutting block being movable relative to the first body along the axial direction of the first abutting shaft, the first abutting block being provided with a first inclined surface, the angle between the first inclined surface and the first abutting shaft being an acute angle; a damper, mounted on the first body, the damper being connected to the first abutting block; a second body being rotatable relative to the first body in a first direction or a second direction, the first direction and the second direction being opposite, when the second body rotates in the second direction, the elastic element contracts; when the second body rotates in the first direction, the first abutting shaft abutting against the first inclined surface moves laterally to drive the first abutting block to move, thereby causing the damper to contract, the damper providing damping for the movement of the first abutting block during the contraction process.

[0008] According to some embodiments of the present invention, the first abutting block is further provided with a first plane, the first plane being connected to one end of the first inclined surface, the first plane being perpendicular to the first abutting axis, wherein the second body is capable of rotating relative to the first body in a first direction to cause the damper to contract, and when the second body rotates in the first direction, the first abutting axis abuts against the first inclined surface and the first plane in sequence.

[0009] According to some embodiments of the present invention, the second abutment block further includes a fourth inclined surface, and the third inclined surface and the fourth inclined surface are respectively connected to the two ends of the second inclined surface. When the second body rotates relative to the first body and compresses the elastic element, the second abutment shaft contacts the fourth inclined surface, the second inclined surface and the third inclined surface in sequence. The included angle between the second inclined surface and the second abutment shaft is a first included angle, and the included angle between the fourth inclined surface and the second abutment shaft is a third included angle. The third included angle is an acute angle and is smaller than the first included angle.

[0010] According to some embodiments of the present invention, the second abutment block further includes a second plane, the second plane being connected to the end of the third inclined surface away from the second inclined surface, and the second plane being perpendicular to the second abutment axis.

[0012] According to some embodiments of the present invention, the first body is provided with a first limiting groove, a portion of the first abutting shaft is slidably disposed in the first limiting groove, the second body is provided with a second limiting groove, and a portion of the second abutting shaft is slidably disposed in the second limiting groove.

[0013] According to a second aspect embodiment of the present invention, a door mounting structure includes: a hinge as described in the first aspect embodiment; a support member, wherein the first main body is fixed to the support member; and a door body, wherein the second main body is fixed to the door body.

[0014] According to the second aspect of the present invention, the door mounting structure has at least the following advantages: the opening or closing process of the door has a buffering effect, and the hinges used to provide the buffering effect are less likely to generate noise and wear.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0023] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0024] Figures 1 to 4 A hinge 100 according to an embodiment of the present invention is shown. The hinge 100 includes a main shaft 105, a first body 101, a second body 102, a first connecting rod 103, a second connecting rod 104, a first abutting shaft 205, a first abutting block 201, and a damper 204. The first body 101 and the second body 102 can be connected to two objects that require a rotatable connection, for example, the first body 101 is connected to a door frame, and the second body 102 is connected to a door.

[0025] The first main body 101 and the second main body 102 are rotatably connected. (Refer to...) Figure 1 The first connecting rod 103 is connected to the first main body 101, and the second connecting rod 104 is rotatably connected to the second main body 102. The main shaft 105 passes through the first connecting rod 103 and the second connecting rod 104, and the first connecting rod 103 and the second connecting rod 104 are rotatably connected through the main shaft 105, thereby realizing the rotatable connection between the first main body 101 and the second main body 102. The specific connection method between the main shaft 105, the connecting rod, and the hinge 100 main body will be described in detail later.

[0026] The first abutment shaft 205, the first abutment block 201, and the damper 204 cooperate with each other, so that the damper 204 can provide damping for the rotation of the hinge 100, thereby buffering the hinge 100 itself or the object connected to the hinge 100. In this application, "rotation of the hinge 100" refers to the relative rotation between the first body 101 and the second body 102.

[0027] Reference Figure 4 The first abutment shaft 205 is parallel to the main shaft 105 and is connected to the first connecting rod 103. (Comparison) Figure 1 and Figure 4 When the second body 102 rotates relative to the first body 101, the second body 102 will drive the first abutment shaft 205 to move laterally via the second connecting rod 104. The "lateral movement" of the first abutment shaft 205 specifically refers to the movement of the first abutment shaft 205 relative to the first body 101, and "lateral" means that the direction of movement of the first abutment shaft 205 is perpendicular to the axis of the first abutment shaft 205. "Lateral" is not necessarily the same as the horizontal direction. When the first abutment shaft 205 is set vertically, the lateral direction is the horizontal direction, but when the first abutment shaft 205 is set in other directions, the lateral direction can be any direction other than the horizontal direction.

[0028] The first abutment block 201 is movably mounted on the first body 101, and the first abutment block 201 is capable of moving axially relative to the first body 101 along the first abutment shaft 205. (Refer to...) Figure 5 The first abutment block 201 is provided with a first inclined surface 401, and the included angle between the first inclined surface 401 and the first abutment shaft 205 is an acute angle. The first abutment block 201 abuts against the end of the first abutment shaft 205, and during the rotation of the hinge 100, the first abutment shaft 205 can abut against the first inclined surface 401. More specifically, Figure 4 In the first body 101, there is a first mounting cavity 301 inside, and a first abutting block 201 is slidably disposed in the first mounting cavity 301. The end of the first abutting shaft 205 passes through the first mounting cavity 301 and abuts against the first abutting block 201. Figure 4In the middle, the first abutting shaft 205 is arranged in the vertical direction, and correspondingly, the first abutting block 201 can move in the vertical direction.

[0029] The damper 204 is mounted on the first main body 101 and is connected to the first abutment block 201. The damper 204 can specifically be a hydraulic damper, a spring damper, etc. (Refer to...) Figure 2 The damper 204 includes a housing 203 and a rod 202. A portion of the rod 202 is disposed inside the housing 203, and a portion of the rod 202 protrudes outside the housing 203. The rod 202 is slidable relative to the housing 203. The installation method of the damper 204 can be referred to... Figure 4 The damper 204 is also disposed in the first mounting cavity 301. The first abutment block 201 is hollow inside, and a part of the damper 204 is housed inside the first abutment block 201. The housing 203 abuts against the wall of the first mounting cavity 301, and the exposed end of the rod 202 abuts against the first abutment block 201. The specific principle and internal structure of the damper 204 are well known in the art and will not be described in detail in this application.

[0030] The second body 102 is rotatable relative to the first body 101, causing the first abutment shaft 205, which abuts against the first inclined surface 401, to move laterally and drive the first abutment block 201 to move. This causes the damper 204 to contract, providing damping to the movement of the first abutment block 201 during the contraction process. The damping provided by the damper 204 to the first abutment block 201 is the damping provided by the damper 204 to the rotation of the hinge 100 or the rotation of the door. "Damper 204 contraction" means that the length of the portion of the damper 204's rod 202 protruding outside the housing 203 decreases.

[0031] by Figure 5 Taking the upper set of dampers 204 and the first abutment block 201 as an example, the left end of the first inclined surface 401 is lower than its right end. When the hinge 100 moves from... Figure 1 The status shown has switched to Figure 4 During the process shown, the top end of the first abutment shaft 205 gradually moves to the left relative to the first inclined surface 401 while maintaining contact with it. Combined with... Figure 4 and Figure 5 The force applied by the first abutment shaft 205 to the first inclined surface 401 has an upward component, which drives the first abutment block 201 to move upward, thereby causing the damper 204 to contract.

[0032] It should be noted that the second body 102 can rotate relative to the first body 101 in either a first direction or a second direction (the first direction is opposite to the second direction). If the second body 102 rotates in the first direction, thereby compressing the damper 204, then rotating the second body 102 in the second direction will not compress the damper 204. During the rotation of the second body 102 in the second direction, the damper 204 will return to its uncompressed state. The first direction is... Figure 1 The middle corresponds to the clockwise direction (from a top-down view), and the second direction is... Figure 1 The direction corresponds to counterclockwise (viewed from above). If the rotation of the second body 102 along the first direction corresponds to the opening process of the door, then the damper 204 provides a buffer for the opening process; if the rotation of the second body 102 along the first direction corresponds to the closing process of the door, then the damper 204 provides a buffer for the closing process.

[0033] The damper 204 provides damping and cushioning for the rotation of the second body 102 in one direction; if damping and cushioning for the rotation of the second body 102 in the opposite direction is required, the hinge 100 may further include a second abutment block 207, a second abutment shaft 209, and an elastic element 208. The cooperation relationship between the second abutment block 207, the second abutment shaft 209, and the elastic element 208 is similar to the cooperation relationship between the first abutment block 201, the first abutment shaft 205, and the damper 204.

[0034] Combination Figure 4 and Figure 5 The second abutment shaft 209 is parallel to the main shaft 105 and is connected to the first connecting rod 103. When the second body 102 rotates relative to the first body 101, the second abutment shaft 209 will move laterally relative to the second body 102. This "lateral" movement of the second abutment shaft 209 means that the direction of movement of the second connecting shaft 210 is perpendicular to the axial direction of the second abutment shaft 209. The second abutment block 207 is movably mounted on the second body 102 and can move axially relative to the second body 102 along the second abutment shaft 209. The second abutment block 207 includes a second inclined surface 404, and the angle between the second inclined surface 404 and the second abutment shaft 209 is an acute angle. The two ends of the elastic member 208 are respectively connected to the second body 102 and the second abutment block 207.

[0035] More specifically, refer to Figure 4 The second main body 102 has a second mounting cavity 302 inside, and the second abutting block 207 and the elastic member 208 are both accommodated in the second mounting cavity 302. The end of the second abutting shaft 209 is inserted into the second mounting cavity 302 and abuts against the second abutting block 207. Figure 4 and Figure 5In this configuration, the elastic element 208 is configured as a spring, and is located on the side of the second abutment block 207 opposite to the second abutment shaft 209. Figure 4 and Figure 7 The second abutment block 207 includes a connecting portion 502 and a contact portion 501 connected to each other. The connecting portion 502 is cylindrical, and an elastic member 208 is sleeved on the outside of the connecting portion 502. One end of the elastic member 208 abuts against the contact portion 501, and the other end abuts against the wall of the second mounting cavity 302. The second inclined surface 404 is provided on the side of the contact portion 501 opposite to the connecting portion 502.

[0036] Figure 5 From Figure 5 The state shown on the left switches to the state shown on the right, corresponding to the second main body 102 rotating relative to the first main body 101 along the first direction; from Figure 5 The state shown on the right switches to the state shown on the left, corresponding to the second body 102 rotating relative to the first body 101 in a second direction. During the rotation of the second body 102 relative to the first body 101 in a first direction, the damper 204 contracts, and the elastic element 208, during the rotation of the second body 102 relative to the first body 101 in the second direction, causes the second abutment shaft 209 to move laterally and push the second inclined surface 404, thereby causing the second abutment block 207 to move and compress the elastic element 208. More specifically, in one embodiment, the door frame and the door are connected by a hinge 100. During the opening process, the damper 204 buffers the rotation of the door, and during the closing process, the elastic element 208 buffers the rotation of the door. Moreover, during the opening process, the elastic force provided by the elastic element 208 can also serve as part of the power to drive the door open.

[0037] Reference Figure 7 In one embodiment, the second abutment block 207 further includes a third inclined surface 405. The angle between the second inclined surface 404 and the second abutment shaft 209 is a first angle, and the angle between the third inclined surface 405 and the second abutment shaft 209 is a second angle. The second angle is an acute angle and is smaller than the first angle. When the second abutment shaft 209 abuts against the third inclined surface 405 and moves laterally, it can also push the second abutment block 207 to move, thereby compressing the elastic element 208. Compared to when the second abutment shaft 209 abuts against the second inclined surface 404, when the second abutment shaft 209 abuts against the third inclined surface 405 and moves laterally, the lateral movement resistance of the second abutment shaft 209 is greater, and the resistance when the second body 102 rotates relative to the first body 101 is greater. Thus, at the end of the process of the hinge 100 rotating and being buffered by the elastic element 208, the buffering effect of the hinge 100 on the door will be stronger, so as to prevent the door from rotating too fast and colliding violently with the door frame.

[0038] In some embodiments, the surface of the abutment block that abuts against the abutment shaft may also include a plane; when the abutment shaft abuts against a plane, the hinge 100 or the door is more likely to maintain an angle or positional stability than when the abutment shaft abuts against a ramp.

[0039] For example, refer to Figure 5 In one embodiment, the first abutment block 201 is further provided with a first plane 402, which is connected to the first inclined plane 401 and is perpendicular to the first abutment shaft 205. The relative position between the first plane 402 and the first inclined plane 401 also satisfies the following: the second body 102 can rotate relative to the first body 101 in a first direction, thereby causing the damper 204 to contract. During the movement of the second body 102 in the first direction, the first abutment shaft 205 abuts against the first inclined plane 401 and the first plane 402 in sequence. If the process of the second body 102 rotating relative to the first body 101 in the first direction corresponds to the closing process of the door, then when the door is just closed, the first abutment shaft 205 abuts against the first plane 402, and the door can be in a relatively stable closed state.

[0040] Similarly, in one embodiment, the second abutment block 207 is further provided with a second plane 403, such as... Figure 5 As shown, the second plane 403 is connected to the end of the third inclined plane 405 away from the second inclined plane 404, and the second plane 403 is perpendicular to the second abutment shaft 209. If the process of the second body 102 rotating relative to the first body 101 in the second direction corresponds to the opening process of the door, then when the door is opened to the maximum angle, the second abutment shaft 209 abuts against the second plane 403, and the door can be relatively stably positioned at that angle.

[0041] It should be noted that, Figure 5 In the state shown on the left, the second abutment block 207 is at the frontal viewing angle. This is only to show the change in contact position between the abutment block and the abutment shaft. In fact, when the hinge 100 rotates to the point where the second abutment shaft 209 abuts against the second plane 403, the first abutment block 201 and the second abutment block 207 will not be at the frontal viewing angle at the same time.

[0042] Reference Figure 7 In one embodiment, the second abutment block 207 further includes a fourth inclined surface 406. The fourth inclined surface 406 and the third inclined surface 405 are respectively connected to the two ends of the second inclined surface 404. The included angle between the fourth inclined surface 406 and the second abutment shaft 209 is a third included angle, which is an acute angle and smaller than the first included angle. The advantage of providing the fourth inclined surface 406 is that it can enhance the resistance of the initial stage of the door opening or closing process, thereby further improving the stability of the door when it is closed or at its maximum opening angle.

[0043] The following is based on Figure 5The movement processes of the first abutment block 201, the second abutment block 207, the first abutment shaft 205, and the second abutment shaft 209 are summarized below. In one embodiment, when the door is closed, the first abutment shaft 205 abuts against the end of the first inclined surface 401 away from the first plane 402, and the second abutment shaft 209 abuts against the second plane 403. When the door is opened to its maximum angle, the first abutment shaft 205 abuts against the first plane 402, and the second abutment shaft 209 abuts against the fourth inclined surface 406. During the opening process, the first abutment shaft 205 gradually moves along the first inclined surface 401 to the first plane 402, and the second abutment shaft 209 sequentially passes through the second plane 403, the third inclined surface 405, the second inclined surface 404, and the fourth inclined surface 406. During the closing process, the first abutment shaft 205 moves from the first plane 402 to the end of the first inclined plane 401 that is away from the first plane 402, and the second abutment shaft 209 passes through the fourth inclined plane 406, the second inclined plane 404, the third inclined plane 405 and the second plane 403 in sequence.

[0044] The following example illustrates the connection method between the main shaft 105, the connecting rod, and the hinge 100 body. For example... Figure 6 As shown, in one embodiment, a first connecting rod 103 passes through a second connecting rod 104, and the first connecting rod 103 and the second connecting rod 104 are interlocked. A main shaft 105 passes through the first connecting rod 103 and the second connecting rod 104 and is located at the intersection of the first connecting rod 103 and the second connecting rod 104. The two ends of the first connecting rod 103 are located on both sides of the main shaft 105, and the two ends of the second connecting rod 104 are also located on both sides of the main shaft 105. One end of the first connecting rod 103 is connected to the first body 101 via a second abutment shaft 209, and the other end of the first connecting rod 103 is connected to the second body 102. One end of the second connecting rod 104 is connected to the first body 101 via a first abutment shaft 205, and the other end of the second connecting rod 104 is connected to the second body 102.

[0045] The hinge 100 further includes a first connecting shaft 206 and a second connecting shaft 210. The first connecting shaft 206 passes through a first connecting rod 103 and a second main body 102, and the first connecting rod 103 and the second main body 102 are rotatably connected via the first connecting shaft 206. The hinge 100 also includes a second connecting shaft 210, which passes through a second connecting rod 104 and a first main body 101, and the second connecting rod 104 and the first main body 101 are rotatably connected via the second connecting shaft 210. (Refer to...) Figure 2 The first body 101 has a first insertion hole 211, the second body 102 has a second insertion hole 212, the first connecting shaft 206 is inserted into the first insertion hole 211, and the second connecting shaft 209 is inserted into the second insertion hole 212.

[0046] The advantage of this embodiment is that the first link 103 and the second link 104 are in a cross-shaped structure, the hinge 100 has a high structural compactness, and each hinge 100 body is connected to the first link 103 and the second link 104. There are many constraints between the first body 101 and the second body 102, and the connection stability between the two and the stability during rotation are high.

[0047] like Figure 1 As shown, in one embodiment, the first body 101 is provided with a first limiting groove 106, and a portion of the first abutting shaft 205 is slidably disposed in the first limiting groove 106. The second body 102 is provided with a second limiting groove 107, and a portion of the second abutting shaft 209 is slidably disposed in the second limiting groove 107. When the second body 102 rotates relative to the first body 101, the first abutting shaft 205 slides along the first limiting groove 106, and the second abutting shaft 209 slides along the second limiting groove 107. The wall surface of the limiting groove can abut against the side surface of the abutting shaft, thereby limiting the movement of the abutting shaft, and thus limiting the rotation angle of the hinge 100. It should be noted that, referring to... Figure 4 The first limiting groove 106 is connected to the first mounting cavity 301, and the first abutting shaft 205 can pass through the first limiting groove 106 into the first mounting cavity 301, thereby abutting against the first abutting block 201; the second limiting groove 107 is connected to the second mounting cavity 302, and the second abutting shaft 209 can pass through the second limiting groove 107 into the second mounting cavity 302, thereby abutting against the second abutting block 207.

[0048] As described above, the hinge 100 of the present invention can be used to achieve a rotational connection between two objects. In some embodiments, the hinge 100 can be applied to the installation of doors. Figure 9 As shown, one embodiment of the present invention also provides a door mounting structure, which includes a door body 602, a support member 604, and a hinge 100 as described in any of the above embodiments. A first main body 101 is fixed to the support member 604, and a second main body 102 is fixed to the door body 602. The support member 604 can be a door frame, a wall, or a partition such as a glass plate 603 or a wooden board erected on the ground. Based on the technical effect of the hinge 100, the door body 602 can be buffered during the opening or closing process, resulting in a better feel when opening or closing the door and improving the user experience.

[0049] like Figure 8 As shown, in one embodiment, the door mounting structure can be part of the shower enclosure. Figure 8In this shower room, there are a wall 601 erected on the ground and two glass panels 603, one of which serves as a support 604. The door 602 can be a glass door. The wall 601, glass panels 603 and door 602 together enclose a space for the user to shower.

[0050] Reference Figure 9 In one embodiment, the door mounting structure further includes a first profile 605 and a second profile 606. The first body 101 is connected to the first profile 605 (e.g., by screws), see reference. Figure 11 The first profile 605 is provided with a first mounting groove 701, and one side edge of the support member 604 is accommodated in the first mounting groove 701. The support member 604 is bonded to the groove wall of the first mounting groove 701. Similarly, refer to... Figure 11 The second body 102 is connected to the second profile 606 (for example, by screws). The second profile 606 is provided with a second mounting groove 702. One side edge of the door body 602 is accommodated in the second mounting groove 702, and the door body 602 is bonded to the groove wall of the second mounting groove 702.

[0051] The support member 604 can be bonded to the wall of the first mounting groove 701 via an adhesive layer (not shown), which is sandwiched between the wall of the first mounting groove 701 and the support member 604. For the already fixed support member 604 and the first profile 605, the adhesive layer can specifically be cured glue. Similarly, the door body 602 can also be bonded to the second mounting groove 702 via an adhesive layer.

[0052] The advantage of using adhesive bonding is that it reduces the number of holes that need to be drilled in the support member 604 and the door body 602, thus reducing the drilling steps in the assembly process of the door mounting structure and improving the ease of assembly. Furthermore, when both the support member 604 and the door body 602 are made of glass, reducing the number of holes also helps to reduce the risk of damage to both the support member 604 and the door body 602.

[0053] Combination Figures 10 to 12 In one embodiment, the first profile 605 is further provided with a third mounting groove 703, in which at least a portion of the first main body 101 is accommodated. The second profile 606 is further provided with a fourth mounting groove 704, in which at least a portion of the second main body 102 is accommodated. The advantage of this arrangement is that it reduces the volume of the portion of the hinge 100 body exposed outside the profile, thereby improving the structural compactness and aesthetics of the door mounting structure.

[0054] Furthermore, as described above, the first body 101 may be provided with a first mounting cavity 301 for mounting the first abutment block 201 and the damper 204. If the first body 101 is connected to the first profile 605, the first profile 605 can cover and close the opening of the first mounting cavity 301 to prevent the damper 204 and the first abutment block 201 from coming out. Moreover, the first profile 605 can constrain the lateral movement of the first abutment block 201, ensuring that the first abutment block 201 moves axially along the first abutment shaft 205. Similarly, if the second body 102 is connected to the second profile 606, the second profile 606 can cover and close the opening of the second mounting cavity 302 to prevent the second abutment block 207 and the damper 204 from coming out. Moreover, the second profile 606 can ensure that the second abutment block 207 moves axially along the second abutment shaft 209.

[0055] 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.
