TECHNICAL FIELD
[0001] The utility model relates to slide rail device technical field especially relates to a slide rail with press rebound and buffer self -locking device. BACKGROUND
[0002] At present, the drawer of various office desks is all installed with the drawer guide rail that can slide freely. In order to make the drawer close to the office desk after closing, it looks neat and beautiful. The method of the prior art is to use the self-closing angle type guide rail that is internationally used, a section of downward slightly inclined guide rail is arranged at the rear end of the fixed rail, the front roller of the sliding rail installed on the drawer is made to slide downward automatically under the action of gravity when walking to the inclined section, so that the drawer is completely closed. However, this self-closing angle type guide rail has the following disadvantages: 1. When the roller of the sliding rail is pushed to the lower sliding end, only the weight of the drawer makes the roller slide downward at an angle of 2.5 to 3 degrees, the downward sliding closing is not obvious, and the use effect is very unsatisfactory; 2. Because the bending angle is small and cannot be self-locked, when the drawer is slightly inclined outward, it may slide out and fall to the ground; 3. Due to the structure, it is not possible to connect smoothly at the bending point when the fixed sliding rail is bent, so when the drawer is pushed and pulled, there is always a feeling of uphill and downhill, which is difficult to meet the requirements of users; 4. Because the drawer does not have a self-locking function, when the table is moved, the drawer is easy to slide out under the action of gravity, causing inconvenience in moving and even damaging the furniture, so it is necessary to make further improvement.
[0003] The existing three-section slide rail does not have a rebound device, and a handle needs to be arranged on the outside of the drawer when installed on furniture, so that the drawer can be pulled, resulting in increased cost, and the handle on the outside of the drawer affects the appearance of the drawer. The resistance when the drawer is opened or closed is large, not smooth, and a lot of effort is needed to pull out the slide rail when opening, which is very inconvenient to use, and the parts may be deformed and damaged after long use.
[0004] The patent with publication number CN112617482A discloses a kind of buffer rebound locking device, including fixed block and movable block, movable block and fixed block sliding connection, fixed block is equipped with frame body, still including buffer sliding block, rebound sliding block, hanging pin, hanging nail, first elastic piece, second elastic piece, frame body is equipped with first sliding groove and second sliding groove, hanging pin is equipped with first shaft body and second shaft body, hanging nail is equipped with third shaft body and fourth shaft body, the end of second sliding groove is equipped with locking position and first avoiding position, the beginning of second sliding groove is equipped with second avoiding position, movable block is equipped with push block and buffer hook.
