Description

Inner slide rail removal mechanism for drawer slide rails

technical field

The utility model relates to the field of drawer slide rails, in particular to an inner slide rail removal mechanism of the drawer slide rails.

Background technique

As shown in Figures 1-3, a common drawer slide rail 7 includes an inner slide rail 71, a middle slide rail 72, an outer slide rail 73 and other components, and the dismantling structure of the inner slide rail 71 is mainly composed of The stop block 721 fixed on the front side of the middle slide rail 72 snaps the catch plate 80 of the dismantling rod 8 provided by the inner slide rail 71 to prevent the inner slide rail 71 from breaking away, and if the inner slide rail 71 and the inner slide rail 71 are to be separated. For the drawer (not shown) connected to the inner slide rail 71, the rod body 81 of the dismantling rod 8 fixed by the inner slide rail 71 must be pulled up or down with fingers so as to pass the aforementioned stop block 721 smoothly. , but it has the following defects:

As shown in Figure 2 and Figure 3, the two sides of the drawer are respectively locked and connected with the inner slide rails 71, and when the two inner slide rails 71 are to be disassembled, the user's hands should be extended from the horizontal direction to both sides of the drawer and then respectively Use your fingers to press up and compress the torsion spring 82 or pull down the rod body 81 of the release lever 8 and compress the torsion spring 82, so it is relatively difficult to apply force with your fingers, which is laborious and uncomfortable;

When the drawer is to be detached, the rod body 81 of the dismantling rod 8 set on the inner slide rails 71 connected to both sides of the drawer must be pulled up by the fingers of one hand of the user and pressed down by the fingers of the other hand. The inner slide rail 71 can be pulled out together with the drawer, and the user must know the direction of the left and right sides, that is, which side of the release lever 8 should be pulled up, and which side of the release lever 8 should be pressed down, thus causing the user to trouble and inconvenience, and the user may not know or forget the direction, or pull away the release lever 8 when the direction is uncertain, resulting in the inability to detach the drawer or due to hard pulling or excessive force. Damage to drawer slides.

As shown in Figure 4 and Figure 5, another common drawer slide rail includes an inner slide rail 92, a middle slide rail 91 and an outer slide rail 93 and other components, wherein the inner slide rail removal structure includes a The block 911 disposed on the middle slide rail 91 and the first positioning group 921 , the second positioning group 922 , the elastic element 923 , the release rod 925 and the connecting rod 926 and other components are disposed on the inner slide rail 92 .

When the above-mentioned structure is used in operation, the first positioning group 921 and the second positioning group 922 can be linked by the dismantling rod 925 or the connecting rod 926 to achieve the purpose of detaching from the stopper 911 of the middle slide rail 91, and the finger does not apply force. Left and right directions must be considered, but due to the complex structure of the components and the relatively high cost of individual processing troubles, it has disadvantages such as troublesome overall assembly operations and waste of manpower and working hours.

Contents of the invention
