Abstract
Description
Technical Field
[0001] This utility model relates to the field of slide rail technology, and in particular to a slide rail buffer device and a slide rail. Background Technology
[0002] Current three-section buffer slides consist of an outer rail, a middle rail, and an inner rail. To enhance their cushioning performance, a buffer is typically installed. The buffer connects to the outer rail of the slide in various ways, such as using the elastic deformation of a clip to achieve a detachable connection. However, current clips are prone to breakage due to excessive travel when subjected to external pressure. Utility Model Content
[0003] To solve the above problems, this technical solution provides a slide rail buffer device.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A slide rail buffer device, comprising
[0006] The fastener includes a fastening body and a fastening buckle disposed on the fastening body, the fastening buckle being used to fasten to the outer rail;
[0007] A sliding element that slides in conjunction with the fixed element;
[0008] The fixing buckle includes a limiting part and a step part for connecting with the limiting part. The step part is used to press against the outer rail when the limiting part is embedded in the fixing hole on the outer rail to limit the fixing buckle from continuing to move in the direction of embedding in the fixing hole.
[0009] In the slide rail buffer device described above, the limiting part and the step part are integrally connected.
[0010] As described above, in a slide rail buffer device, the fixing body includes a first abutting surface that abuts against the end face of the outer rail, and the limiting part includes a second abutting surface that abuts against the side wall of the fixing hole. The first abutting surface and the second abutting surface together clamp the outer rail to restrict the movement of the fixing member relative to the outer rail.
[0011] In the slide rail buffer device described above, the distance 'a' between the first contact surface and the second contact surface is 6.2 ± 0.5 mm.
[0012] As described above, in a slide rail buffer device, the fixed body has a limiting groove at its end for a limiting protrusion on the outer rail to be inserted into. The limiting groove includes a guide portion and a limiting portion recessed from the end face of the fixed body. The guide portion gradually narrows along the direction from the end face of the fixed body to the limiting portion.
[0013] The slide rail buffer device described above also includes
[0014] A spring, the two ends of which are respectively connected to the fixed member and the sliding member;
[0015] A damper is disposed on the sliding member, and its output end is connected to the fixed member;
[0016] The spring causes the fixed member and the sliding member to tend to move closer to each other, and the damper is used to provide resistance when the fixed member and the sliding member move closer to each other.
[0017] As described above, in a slide rail buffer device, the fixed body is provided with first fixing parts on both sides for fixing the ends of the springs, and the sliding member is provided with second fixing parts on both sides for fixing the other ends of the springs. The two springs respectively cooperate with the two first fixing parts and the two second fixing parts.
[0018] The slide rail includes a slide rail buffer device as described above, an outer rail, and an inner rail that slides in cooperation with the outer rail. The fixing member is fixed on the outer rail, and the sliding member is connected to the inner rail.
[0019] As described above, the outer rail has fixing holes.
[0020] As described above, the outer rail has an L-shaped limiting protrusion stamped out.
[0021] The beneficial effects of this application are:
[0022] This utility model provides a slide rail buffer device. When the fixing member is installed on the outer rail, the fixing buckle is embedded in the fixing hole of the outer rail. When the fixing buckle is pressed by an external force, the stepped part will press against the outer rail and use the outer rail to support it, so as to prevent the limiting part from continuing to move in the direction of embedding in the fixing hole. This can prevent the fixing buckle from breaking due to excessive deformation caused by excessive bending stroke. Attached Figure Description

[0028] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] A slide rail buffer device, comprising
[0030] The fastener 1 includes a fastening body 11 and a fastening buckle 12 disposed on the fastening body 11, the fastening buckle 12 being used to fasten to the outer rail;
[0031] Sliding member 2, which slides in conjunction with the fixing member 1;
[0032] The fixing buckle 12 includes a limiting part 121 and a step part 122 for connecting with the limiting part 121. The step part 122 is used to press against the outer rail when the limiting part 121 is embedded in the fixing hole on the outer rail to limit the fixing buckle 12 from continuing to move in the direction of embedding in the fixing hole.
[0033] This utility model provides a slide rail buffer device. When the fixing member is installed on the outer rail, the fixing buckle is embedded in the fixing hole of the outer rail. When the fixing buckle is pressed by an external force, the stepped part will press against the outer rail and use the outer rail to support it, so as to prevent the limiting part from continuing to move in the direction of embedding in the fixing hole. This can prevent the fixing buckle from breaking due to excessive deformation caused by excessive bending stroke.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting part 121 and the step part 122 are integrally connected, thereby increasing structural strength.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the fixing body 11 includes a first abutting surface 111 that abuts against the end face of the outer rail, and the limiting part 121 includes a second abutting surface 123 that abuts against the side wall of the fixing hole. The first abutting surface 111 and the second abutting surface 123 together clamp the outer rail to restrict the movement of the fixing member 1 relative to the outer rail. After the limiting part is inserted into the fixing hole, the movement of the fixing member relative to the outer rail is restricted.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the distance 'a' between the first abutment surface 111 and the second abutment surface 123 is 6.2 ± 0.5 mm. Existing fixing holes on the outer rail are prone to breakage due to the punching process being too close to the edge of the outer rail. For example... Figure 4 As shown, when the outer rail mates with the fastener, the increased size of 'a' prevents breakage at that point.
[0037] Furthermore, as a preferred embodiment and not a limitation of this solution, the end of the fixing body 11 is provided with a limiting groove 13 for the insertion of a limiting protrusion on the outer rail. The limiting groove 13 includes a guide portion 131 and a limiting portion 132 recessed from the end face of the fixing body 11. The guide portion 131 gradually narrows along the direction from the end face of the fixing body 11 to the limiting portion 132, thus preventing the fixing component from shaking.
[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes...
[0039] Spring 3, with its two ends connected to the fixing member 1 and the sliding member 2 respectively;
[0040] The damper 4 is disposed on the sliding member 2, and its output end is connected to the fixed member 1;
[0041] The spring 3 causes the fixed member 1 and the sliding member 2 to tend to move closer to each other, and the damper 4 provides resistance when the fixed member 1 and the sliding member 2 move closer to each other.
[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the fixed body 11 is provided with first fixing parts 14 on both sides for fixing the ends of the springs 3, and the sliding member 2 is provided with second fixing parts 15 on both sides for fixing the other ends of the springs 3, and the two springs 3 are respectively connected to the two first fixing parts 14 and the two second fixing parts 15.
[0043] The slide rail includes a slide rail buffer device as described above, an outer rail 5, and an inner rail that slides in cooperation with the outer rail 5. The fixing member 1 is fixed on the outer rail 5, and the sliding member 2 cooperates with the inner rail.
[0044] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the outer rail 5 is provided with fixing holes 51.
[0045] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, an L-shaped limiting protrusion 52 is stamped on the outer rail 5.
[0046] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
