In the embodiment of the invention, the height of the supporting frame 21 is adjusted by controlling the lifting of the lifting assembly, and the lifting auxiliary slideway can effectively increase the smoothness of the lifting assembly during lifting, thereby being beneficial to prolonging the service life of the height adjusting device of the embodiment of the invention.
In some embodiments, referring to fig. 2 and 3, one end of the lifting auxiliary slideway 41 is connected with the base frame 11, and the other end of the lifting auxiliary slideway 41 is connected with the supporting frame 21; the lifting auxiliary slideway 41 comprises a plurality of connecting rods which are movably connected in sequence, and the plurality of connecting rods are in a folded line shape.
Specifically, along the direction from high to low, the upper end of the first connecting rod is hinged with the support frame 21, and the lower end is connected with the second connecting rod. That is, the first connecting rod can rotate relative to the supporting frame 21. The seat frame further comprises a cross rod 414, the cross rod 414 is fixedly connected with the base frame 11, and one end of the last connecting rod of the lifting auxiliary slideway 41 is hinged with one end of the cross rod 414. That is, the last connecting rod can rotate relative to the cross bar 414. The number of the connecting rods can be set according to the needs, specifically, three connecting rods are respectively a first connecting rod 411, a second connecting rod 412 and a third connecting rod 413.
Wherein, the connecting rods of the lifting auxiliary slide way 41 are provided with movable grooves 410 extending along the length direction of the connecting rods, the lifting auxiliary slide way 41 further comprises a first connecting piece 43, and the first connecting piece 43 is arranged in the movable grooves 410 of two adjacent connecting rods in a penetrating way, so that the two connecting rods are connected. The first connecting piece 43 can move in the movable groove 410, and two adjacent connecting rods are movably connected through the first connecting piece 43.
