Detailed Description

To facilitate an understanding of the invention, the invention is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete. It should be noted that the terms "first" and "second" in the present invention do not denote any particular quantity or order, but rather are used for distinguishing names.

Referring to fig. 1 to 4, in the present embodiment, a self-closing buffer for a slide rail is fixedly mounted on a movable slide rail or a fixed slide rail, and is used for fixedly arranging a fixed collision block (not shown) on the fixed slide rail or the movable slide rail to match with the fixed collision block (not shown), specifically, the self-closing buffer comprises a self-closing box 1, a damper 5 and a self-closing tension spring 6 which are fixedly arranged on the self-closing box 1, a damping connection block 2, a tension spring connection block 3 and a self-closing collision piece 4 which are slidably connected to the self-closing box 1, wherein the self-closing collision piece 4, the tension spring connection block 3 and the damping connection block 2 of the present embodiment are sequentially arranged along a front end to a tail end direction of the self-closing box 1, that is, guide portions which are pre-formed on the damping connection block 2, the tension spring connection block 3 and the self-closing collision piece 4 and are in sliding fit with guide grooves which are pre-formed on the self-closing box, The tension spring connecting block 3 and the damping connecting block 2 can move along the direction of the self-closing box 1.

In this embodiment, the avoiding slot 11 for the self-closing touch piece 4 to rotate and avoid is formed at the front end of the self-closing box 1, that is, the tail end of the self-closing touch piece 4 is hinged to the front end of the tension spring connecting block 3, wherein the other end of the tension spring connecting block 3 is provided with a sleeve box position and the self-closing touch piece 4 is provided with a circular connecting position, and the circular connecting position is sleeved on the sleeving position, so that the self-closing touch piece 4 and the tension spring connecting block 3 can synchronously move and the self-closing touch piece 4 can swing around the sleeving position.

In this embodiment, two ends of the self-closing tension spring 6 are respectively connected with the self-closing box 1 and the tension spring connecting block 3, so that when the elastic force of the self-closing tension spring 6 is used for rebounding, the tension spring connecting block 3 and the self-closing touch piece 4 rebound and move towards the tail end direction of the self-closing box 1 under the condition of no obstruction; on the contrary, when the tension spring connecting block 3 and the self-closing touch piece 4 move towards the front end direction of the self-closing box 1, the elastic force action of the self-closing tension spring 6 needs to be overcome.

In this embodiment, the damper 5 is fixedly installed in a fixing groove preset at a rear end position of the self-closing box 1, the piston rod 51 of the damper 5 can automatically and elastically extend out (i.e. the piston rod 51 can automatically and elastically extend out towards a front end direction of the self-closing box 1), and a rod end of the piston rod 51 of the damper 5 is connected with the damping connection block 2 so that the damping connection block 2 and the piston rod 51 move synchronously. In addition, the front end of the damping connecting block 2 can be abutted and collided with the tail end of the tension spring connecting block 3.

When the self-closing touch piece 4 and the tension spring connecting block 3 synchronously move to the front end position of the self-closing box 1, the self-closing touch piece 4 can rotate to enter the avoiding groove position 11. In addition, the self-closing latch 4 of the present embodiment is formed with an arc-shaped shift 41 which is in contact engagement with the fixed latch. For ease of understanding, the self-closing bumper described above is explained below with reference to specific methods of use: when the movable slide rail and the fixed slide rail relatively slide and open, the fixed collision block moves along with the movable slide rail or the fixed slide rail, and the fixed collision block is embedded into the arc-shaped gear 41 to synchronously drive the self-closing collision piece 4 to move towards the front end direction of the self-closing box 1 (the self-closing collision piece 4 and the tension spring connecting block 3 synchronously move at the moment) until the self-closing collision piece 4 moves to the avoiding groove position 11 and rotates to enter the avoiding groove position 11, the self-closing collision piece 4 avoids the fixed collision block, and the self-closing collision piece 4 and the tension spring connecting block 3 are limited to stop moving. And need overcome the elastic action of self-closing extension spring 6 at the in-process of self-closing touch 4 and extension spring connecting block 3 synchronous motion, simultaneously, because extension spring connecting block 3 can keep away from damping connecting block 2 gradually, make damping connecting block 2 no longer receive the conflict restriction of damping connecting block 2 in order to make piston rod 51 independently elasticity stretch out and synchronous damping connecting block 2 move towards self-closing box 1 front end direction, finally damping connecting block 2 can collide with limited extension spring connecting block 3 conflict.

On the contrary, when the movable slide rail and the fixed slide rail are closed in a relative sliding way, the fixed collision block and the fixed collision block move along with the movable slide rail or the fixed slide rail, so that the fixed collision block is contacted and collided with the self-closing collision piece 4 positioned in the avoiding slot position 11, so that the self-closing touch piece 4 rotates to exit the avoidance slot position 11 and the fixed touch block is embedded into the arc-shaped gear 41 to move synchronously with the self-closing touch piece 4, the self-closing touch block and the tension spring connecting block 3 are driven to synchronously move towards the tail end direction of the self-closing box 1 under the action of the elastic contraction potential energy of the self-closing tension spring 6, and in the moving process, the tension spring connecting block 3 is in contact collision with the damping connecting block 2, thereby gradually squeezing the piston rod 51 to contract so that the tension spring connecting block 3 and the damping connecting block 2 need to overcome the damping action of the damper 5 to move towards the tail end of the self-closing box 1, in this way, the damping connecting block 2 and the tension spring connecting block 3 play a damping and buffering effect.

Referring to fig. 4, specifically, the damper 5 for autonomous elastic extension of the present embodiment may refer to the damper 5 for furniture disclosed in chinese patent CN2005201203264, that is, the damper 5 includes a cylinder and a piston rod 51, and a piston 52 and a compression spring 53 are disposed at one end of the piston rod 51, wherein the elastic potential energy of the compression spring 53 is utilized to drive the piston 52 and the piston rod 51 to synchronously and elastically extend outwards.

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention. Therefore, the content of the technical scheme of the utility model, according to the equivalent change made by the idea of the utility model, should be covered in the protection scope of the utility model.
