Description

Technical Field

[0001] The utility model relates to the technical field of cover opening slide rails, and more specifically, to a draw-out cover opening slide rail for a material storage box. Background Art

[0002] The main use of the slide rail for the pull-out cover of the storage box is its convenience. The slide rail design makes the opening and closing of the pull-out cover smoother and easier. Users can easily open or close the storage box without any effort. Secondly, the high-quality slide rail can ensure that the pull-out cover remains stable when opening or closing, avoiding shaking or sudden closing, thereby protecting the items in the storage box from damage. In the existing public literature, the patent with patent publication number CN220141164U discloses a slide rail assembly, which can relatively fix the outer slide rail and the inner slide rail by a linkage mechanism when the positioning end is in the second position. The inner and outer slide rails can be directly and effectively relatively fixed in both the retracted state and the extended state, thereby effectively avoiding the problem of the inner and outer slide rails moving on their own in unexpected situations, and then effectively ensuring that the state between the inner and outer slide rails can be maintained continuously and stably; however, the component has the following defects;

[0003] Although the slide rail can play a guiding role in the process of pulling out the storage box, it is difficult to open or close the cover of the storage box during the movement on the rail. This results in the cover needing to be manually opened or closed after the storage box is pulled out. It is difficult to automatically open the cover when pulling the storage box or automatically close the cover when pushing the storage box. The storage box is inconvenient to use, so a slide rail is needed to pull out and open the cover of the storage box. Utility Model Content
