[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0022] Embodiment 1:

[0023] Referring to Figures 1-4 , the two-section hidden slide rail self-locking device comprises a fixed rail 1 and a movable rail 2, the movable rail 2 is slidably connected to the fixed rail 1, and further comprises:

[0024] A self-locking device main body 4 is fixedly connected to the fixed rail 1.

[0025] A yoke 201 is fixedly connected to the movable rail 2.

[0026] The movable rail 2 drives the yoke 201 to move, the yoke 201 slides into the self-locking device main body 4, and is clamped with the self-locking device main body 4.

[0027] A limiting groove 2011 is formed in the yoke 201, a limiting convex 401 is fixedly connected to the self-locking device main body 4, and the limiting groove 2011 is matched with the limiting convex 401.

[0028] Referring to Figures 3-4 When the drawer is closed, the drawer will drive the movable rail 2 to move, and the movable rail 2 will synchronously drive the pawl 201 fixedly connected thereto to move inward. After the pawl 201 moves a certain distance, the pawl 201 will move into the self-locking body 4, and the pawl 201 entering the self-locking body 4 will be clamped with the limiting convex 401. At this time, the limiting convex 401 buckles and locks the pawl 201;

[0029] Referring to Figures 3-4 When the drawer is opened, the drawer is pulled outward, and the drawer will drive the movable rail 2 to move. The pawl 201 on the movable rail 2 will synchronously move outward. At this time, the pawl 201 will extrude the limiting convex 401. After the limiting convex 401 is extruded, it will slide out of the limiting groove 2011 of the pawl 201. At this time, the pawl 201 is released from the limiting position, and the drawer can be pulled out.

[0030] Through the cooperation of the pawl 201 and the limiting convex 401 in the device, when the drawer is closed, the movable rail 2 will not automatically slide out, preventing the slide rail from being vibrated and not being installed standardly and the drawer from sliding out due to the inclination of installation, thereby improving the stability and safety of the drawer slide rail during use.

[0031] The self-locking body 4 is provided with a positioning groove 402.

[0032] Referring to Figure 4 Through the positioning groove 402 provided on the self-locking body 4, when the pawl 201 slides synchronously with the movable rail 2, the pawl 201 can stably slide into the positioning groove 402, thereby enabling the pawl 201 to stably clamp with the limiting convex 401.

[0033] It should be noted that the limiting convex 401 is a triangular-shaped elastic convex. When the pawl 201 slides into the positioning groove 402 and contacts the limiting convex 401, the limiting convex 401 can be reset and pop up after being extruded and deformed, so as to ensure that the limiting convex 401 can be stably clamped into the limiting groove 2011.

[0034] The positioning groove 402 is a beveled groove.

[0035] Referring to Figure 4 By setting the front section of the positioning groove 402 as a beveled groove, the pawl 201 can be conveniently slid into the positioning groove 402.

[0036] The fixed rail 1 is slidably connected with a retainer 3 with a steel ball 301, and the retainer 3 is slidably connected with the movable rail 2.

[0037] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and inventive concept of the present application, can make equivalent substitutions or changes within the technical range disclosed by the present application, which should be encompassed in the protection scope of the present application.
