Detailed Description
The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments. The following embodiments do not limit the invention to which the claims refer. Moreover, all combinations of features described in the embodiments are not necessarily essential to the solution of the invention.
Example one
As shown in fig. 1, 2, 3, 4, and 5, an example of a lifting adjusting device disposed on a seat base 7 and a backrest 8 includes a positioning portion and a lifting adjusting portion moving relative to the positioning portion, the positioning portion is a seat post 1, the lifting adjusting portion is a sleeve 2 sleeved on the seat post, the seat post is provided with positioning holes 101 arranged up and down, the sleeve is provided with a positioning switch capable of being locked on the positioning holes, the positioning switch includes a stop pin 3, one end of the stop pin is provided with a positioning hook 301 facing the positioning hole, the other end of the stop pin is a pressing end 302, and a pin body of the stop pin between the pressing end and the positioning hook is rotatably connected with the lifting adjusting portion through a shaft 4.
And a return spring 5 is arranged between the pressing end and the lifting adjusting part, so that the positioning hook is inserted into the positioning hole in a normal state. The stop pin is sleeved with a key sleeve 6, namely a plastic part sleeved on the stop pin, so that the finger can press the stop pin conveniently.
The key sleeve is provided with a reset spring positioning cavity relative to the lifting adjusting part, and the reset spring positioning cavity is positioned on the pressing end side of the stop pin. The key sleeve part at the position of the reset spring positioning cavity is pressed by fingers, so that the positioning hook is separated from the positioning hole, the sleeve can freely slide up and down on the seat pillar and move to a required height position, the pressing position is loosened, and the positioning hook is inserted into the positioning hole under the action of the reset spring, so that the sleeve is fixed relative to the seat pillar.
