Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in figures 1, 4 and 5, the invention comprises a slide core 11 and a slide shell 14, wherein the slide core 11 is in a C shape, and the slide shell 14 is approximately in a C shape. The sliding shell 14 is provided with a bulge 17, the bulge 17 is semicircular, and the bulge 17 is in line contact with the sliding core 11. The two bulges 17 form a group, the bottom of the sliding shell 14 is provided with two groups of bulges 17, and the side surface of the sliding shell 14 is provided with a bulge 17. The sliding core 11 and the sliding shell 14 are in line contact and slide smoothly, the structure is compact, and the occupied space is small. The slide core 11 is snapped together with the slide case 14 and the slide core 11 slides on the slide case 14. As shown in fig. 1 and 2, an unlocking lever stopper 5 is provided at the top of the front end of the slide core 11. An unlocking rod 6 is arranged between the unlocking rod limiting blocks 5. The lock release lever stopper 5 has a function of limiting the lock release lever 6. The top of the rear end of the slide core 11 is provided with an unlocking rod limiting hole 15. One end of the unlocking rod 6 is C-shaped. One end of the unlocking rod 6 is clamped on the sliding core 11 through an unlocking rod limiting hole 15. The other end of the unlocking rod 6 is provided with a handle 1. The unlocking rod 6 between the unlocking rod limiting block 5 and the unlocking rod limiting hole 15 is provided with a locking claw 8. A limiting upright post 7 is arranged between the locking claw 8 and the sliding core 11, a reset spring 9 is sleeved on the limiting upright post 7, and a locking block 10 is arranged at the bottom of the locking claw 8. As shown in fig. 1 and 3, the bottom of the slide core 11 and the slide shell 14 are provided with locking holes 16, and the locking holes 16 are equally spaced and uniformly distributed. In this embodiment, there are 3 locking blocks 10 and they are matched with the locking holes 16. One end of the sliding shell 14 is provided with a first positioning hole 2, the end of the sliding core 11 opposite to the sliding shell 14 is provided with a second positioning hole 13, and a sliding core power-assisted spring 3 is arranged between the first positioning hole 2 and the second positioning hole 13. As shown in fig. 5, a first stopper 4 is disposed at the front end of the sliding shell 14, and a second stopper 12 is disposed at the rear end of the sliding shell 14. The first stopper 4 and the second stopper 12 have a function of limiting the forward and backward sliding distance of the locking claw 8, and prevent the slide core 11 from being separated from the slide case 14. The sliding core power-assisted spring 3 provides auxiliary stretching force when the automobile seat is adjusted forwards, and the force is saved when the automobile seat is adjusted.
