[0020] The following are specific embodiments of the present invention in combination with the drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0021] Such as Figure 1 、 Figure 2As shown in the figure, the seat adjuster of the present invention includes an adjustment disc 1, a connecting member 2, and an adjustment handle 3. The connecting member 2 and the adjustment handle 3 are movably connected inside the adjustment disc 1. A gear disc 4 for facilitating rotational adjustment is provided inside the adjustment disc 1. An auxiliary mechanism for locking and unlocking the gear disc 4 is also provided inside the adjustment disc 1. The auxiliary mechanism includes a clamping member 5 for clamping and limiting the gear disc 4, a torsion spring 6 for elastically resetting the clamping member 5, and a movable block 7 for facilitating the unlocking and adjustment of the gear disc 4. The movable block 7 is movably connected to the end of the adjustment handle 3 through a pin shaft 8 and is located inside the adjustment disc 1. A disc spring 9 for elastic resetting is provided on the connecting member 2. The gear disc 4, the connecting member 2, and the disc spring 9 are stacked and installed inside the adjustment disc 1 in sequence from bottom to top and are movably connected to the adjustment disc 1 through a connecting shaft. The connecting member 2 has a connecting column 10 for connecting the corresponding end of the disc spring 9. Both ends of the disc spring 9 are connected to the connecting shaft and the connecting column 10 respectively. The movable block 7 can push open the clamping member 5 through the rotation of the adjustment handle 3 and separate from the gear disc 4.
[0022] The above structural design is reasonable. By controlling the displacement of the movable block 7 through the adjustment handle 3, the two clamping members 5 are pushed open and separated from the gear disc 4, realizing unlocking and rotational adjustment. The structure is more stable. Compared with traditional ones, there are fewer parts used in the adjuster, which is convenient for installation and has a low manufacturing cost, and is more flexible.
[0023] Preferably, in order to facilitate the locking of the gear disc 4 and quick unlocking, the number of clamping members 5 is 2. The two clamping members 5 are arranged in a "V" - shaped structure and cooperate with the gear disc 4. The corresponding ends of the two clamping members 5 are movably connected to the inside of the adjustment disc 1 through a rotating shaft.
[0024] Preferably, a limiting frame 11 for limiting the movement of the end of the adjustment handle 3 is further provided inside the adjustment disc 1. An adjustment hole 12 for facilitating the penetration of the pin shaft 8 and for movement limiting is provided on the limiting frame 11. The limiting frame 11 and the adjustment disc 1 are integrally formed.
