Self-locking drawer slide track

Abstract

The invention relates to a self-locking drawer slide track, which is a three-level telescopic slide track device capable of extending in a three-level manner. The three-level telescopic slide track has a function of preventing a drawer from opening due to shaking. The technical scheme includes that the self-locking drawer slide track comprises outer tracks, middle tracks and inner tracks which are mutually nested in an overlying manner, slide strips with roll balls are respectively mounted between each outer track and the corresponding middle track and between each middle track and the corresponding inner track, limiting structures are respectively arranged on the outer tracks, the middle tracks and the inner tracks and prevent the outer tracks, the middle tracks and the inner tracks from being separated from each other, a lock catch is fixed at the front end of each outer track, and fastener teeth are arranged at the front end of each inner track; and the inner tracks are fixed on a furniture body, the outer tracks are fixed on two outer side walls of the drawer, when the drawer is closed, the fastener teeth and the lock catches are mutually fastened, and accordingly the problem that the drawer opens automatically due to shaking is avoided. When needing to be opened manually, the drawer is pressed to the direction of the furniture body by a small distance, and can be freely opened in the small distance.

Description

technical field [0001] The invention relates to hardware fittings for furniture, in particular to a drawer slide rail that can be locked automatically to prevent drawers from being automatically opened. Background technique [0002] Generally, in existing furniture, relatively sliding slide rails need to be installed between the drawer and the main body of the furniture, so as to increase the drawability of the drawer. However, it is precisely because of the setting of the slide rail that the activity between the drawer and the main body of the furniture increases, and it also prevents the furniture from being unstable or during the relocation process, the drawer will automatically open due to the effect of gravity, which not only causes trouble for the relocation work A lot of trouble, and it is easy to lose the items contained therein. At present, some drawer slides are equipped with a closed clamping structure to prevent the movable parts of the furniture from being open...

Problems solved by technology

However, it is precisely because of the setting of the slide rail that the activity between the drawer and the main body of the furniture increases, and it also prevents the furniture from being unstable or during the relocation process, the drawer will automatically open due to the effect of gravity, which not only causes trouble for the relocation work A lot of trouble, and it is easy to lose the items contained in it

At present, some drawer slides are equipped with a closed clamping structure to prevent the movable parts of the furniture from being opened at will, but because the clamping structure of these slides is generally relatively simple, it is usually a protruding point or a welding point. When these sliding parts shake and vibrate, the existing slide rails will still open by themselves, and the effect of preventing automatic opening is not very satisfactory
