Benefits of technology
[0008]An objective of the present invention is to provide a slide rail buffering structure that provides excellent buffering effect to a slide rail in the returning course of the slide rail so as to extend the service life of the slide rail.
[0009]Another objective of the present invention is to provide a slide rail structure, which improves the coupling strength between a positioning bar and a slide block to prevent damage to the structure caused by undesired separation of parts and thus protect the safety of users.
[0010]To achieve the above objectives, the present invention provides a slide rail buffering structure, comprising: a connection board, which is mounted to a rail base plate, the connection board forming therein an accommodation channel, the connection board having a bottom having opposite sides defining fixing slots, the connection board having an end that extends to form a track portion, the track portion defining a slide channel, the slide channel having a distal end that is bent to define a holding receptacle, the track portion having a distal end forming a support; a slidable board, which is set on the track portion of the connection board, the slidable board having a bottom having opposite sides defining fixing slots and a top defining a through hole, the slidable board also forming a receiving opening in the bottom thereof, a damper, which is received in the accommodation channel of the connection board, the damper comprising a connection rod, the connection rod having an end coupled to the receiving opening of the slidable board to allow the slidable board to be movable along the track portion of the connection board; a pull-resistant assembly, which has an end engaging and fixed to the fixing slots defined in the bottom of the connection board and an opposite end engaging and fixed to the fixing slots defined in the slidable board; and a positioning bar, which is movably received in the slide channel of the track portion, the positioning bar having a top end extending through the through hole of the slidable board to guide sliding path of the slidable board, whereby when the positioning bar is caught and driven by a guide section of a rail plate, the positioning bar is guided to move out of the holding receptacle of the slide channel, and the slidable board is acted upon by a pulling force of the pull-resistant assembly to move backward for effecting a returning movement. The slidable board uses the buffering effect induced by the damper to alleviate the pulling / pushing forces that drive the rail plate to return to a given position.
Problems solved by technology
The known drawer is certainly not a perfect device and thus further improvement is needed.
Although the smoothness of operation is improved, a drawback accompanies the improvement in that when the slide rail is acted upon by an external force to return to a given position, due to the inertial force and reaction force, it is often subjected to undesired sliding motion, which leads to poor engagement between the drawer and the drawer cavity of the cabinet.
(1) To realize fast positioning for tightly stowing the slide rail, the conventional slide rail makes use of the pulling force provided by a spring to drive backward the slide rail that is closed to a track end and to ensure that he slide rail, after long-term repeated use, may still be capable of realizing automatic returning, the pulling force of the spring is often increased, so that the impact and wearing between the slide and the rail is increased, leading to shortening of the lifespan of the slide rail.
(2) Due to the repeated impact occurring in the returning operation of the conventional slide rail, separation may easily occur due to improper assembling or incorrect application force by a user, leading to hurt of the user, such as jamming.
Apparently, the known techniques are still of insufficiency and drawbacks and further improvement is needed.

A slide rail buffering structure includes a connection board, a slidable board, a damper, a pull-resistant assembly, and a positioning bar. The positioning bar is received in a slide channel of the connection board. The slidable board is fit over the positioning bar and is set on the track portion of the connection board. The damper is received in an end of the connection board and the damper is coupled to the slidable board. The pull-resistant assembly is connected between the slidable board and the connection board and is set at an end of a rail base plate. The structure of the present invention allows the positioning bar to be caught and driven by a guide section of a rail plate to alleviate and buffer the pulling force of the connection board that is moved backward for returning so as to prevent damage caused by excessive pulling force.
Description
TECHNICAL FIELD OF THE INVENTION [0001]The present invention generally relates to buffering technique applicable to an object having a slide rail structure, such as a drawer or a cabinet, and more particularly to a slide rail buffering structure that comprises a damper connected to a slidable board to alleviate and buffer pulling / pushing forces acting upon the slidable board.DESCRIPTION OF THE PRIOR ART [0002]Among devices for storing and organizing objects, a drawer is a long-developed and widely used device and finds its application everywhere. The drawer has a very simple function so that even though it has been developed for quite a long time, there is much improvement can be made of the drawer and no elaborate improvement has ever done on the drawer. The known drawer is certainly not a perfect device and thus further improvement is needed.[0003]A conventional drawer, which is movably received in a drawer cavity defined in a cabinet, is often provided with rail-and-slide pair be...
