AI Technical Summary
In the self-locking mechanism of a refrigerator drawer, the locking pin is prone to coming off, causing the self-locking mechanism to fail and preventing the drawer from closing properly.
A downward-extending lower slot is provided at the front end of the slide. When the inner rail is pulled out, the locking post moves into the lower slot for positioning and is stabilized by gravity. When the inner rail retracts, the guide part lifts the locking post out of the lower slot, and the locking post is locked back into the upper slot. Combined with the limiting slot and speed reduction component, smooth sliding is ensured.
It effectively prevents the drawer from coming off the hook, ensuring that the drawer can stably and self-lock back into place, thus improving the self-locking performance of the slide rails.

Abstract
Claims
1. A self-locking refrigerator slide rail, characterized by: It includes slide rails installed on both sides of the refrigerator. The slide rails include an outer rail (1) for fixing to the refrigerator, an inner rail (2) for sliding relative to the outer rail (1), and a self-locking device (3) provided on the outer rail (1). The self-locking device (3) includes a fixing member (31) detachably connected to the outer rail (1), a sliding member (32) sliding relative to the fixing member (31), a locking pin (33) sliding relative to the sliding member (32), and a self-locking spring (34) disposed between the fixing member (31) and the sliding member (32). The fastener (31) is provided with a sliding groove (311), and the front end of the sliding groove (311) is provided with a downwardly extending lower slot (312); When the inner rail (2) is pulled out, it drives the locking pin (33) to move to the front end of the slide groove (311) and then falls into the lower locking groove (312).
2. The self-locking refrigerator slide rail according to claim 1, characterized in that: The inner rail (2) is provided with a groove (21) for engaging with the locking post (33). The groove (21) is provided with an upwardly extending first groove (22) and a second groove (23), as well as a guide part (24) connecting the second groove (23). When the inner rail (2) retracts, the guide part (24) lifts the locking post (33) so that the locking post (33) disengages from the lower locking groove (312).
3. The self-locking refrigerator slide rail according to claim 2, characterized in that: The rear end of the slide (311) is provided with an upwardly extending upper slot (313). When the inner rail (2) retracts, the second groove (23) and the upper slot (313) overlap, and the locking post (33) rises along the guide (24) to simultaneously engage with the second groove (23) and the upper slot (313).
4. The self-locking refrigerator slide rail according to claim 2, characterized in that: A limiting groove (314) is formed between the fixing member (31) and the outer rail (1) for the sliding member (32) to slide. The bottom surface of the sliding member (32) is provided with a protrusion (321) or a protrusion (322).
5. The self-locking refrigerator slide rail according to claim 2, characterized in that: The sliding member (32) is provided with a vertical groove (323) for the locking post (33) to move up and down. The back of the fixing member (31) is provided with a limiting cavity (315). The locking post (33) includes a column portion (331) protruding from the sliding groove (311), a limiting portion (332) located on the limiting cavity (315), and a shaft portion (333) located in the vertical groove (323).
6. A self-locking refrigerator slide rail according to claim 5, characterized in that: The diameter of the limiting part (332) is greater than the width of the groove (311).
7. The self-locking refrigerator slide rail according to claim 1, characterized in that: An intermediate rail (4) is provided between the outer rail (1) and the inner rail (2), and a speed-reducing component (5) is provided on the self-locking device (3) for reducing the speed of the intermediate rail (4).
8. A self-locking refrigerator slide rail according to claim 7, characterized in that: The front end of the fixing member (31) is provided with a T-shaped groove (316) that communicates with the bottom surface. The deceleration member (5) is I-shaped. The T-shaped groove (316) allows the deceleration member (5) to be inserted into the bottom surface of the self-locking device (3).
9. The self-locking refrigerator slide rail according to claim 7, characterized in that: The speed reduction component (5) has a raised rib (51) on its side.
10. The self-locking refrigerator slide rail according to claim 1, characterized in that: The fixing part (31) comprises a main body part (317) and cavities (318) arranged on the upper and lower sides of the main body part (317), the sliding part (32) comprises a main plate part (324) and buckle parts (325) arranged on the upper and lower sides of the main plate part (324), the buckle parts (325) are buckled with the main body part (317) so that the sliding part (32) slides relative to the fixing part (31).
