Description

A multi-degree-of-freedom student seat

technical field

The utility model relates to the technical field of seats, in particular to a multi-degree-of-freedom student seat.

Background technique

In general, the seats used by students in schools are relatively simple seats with a single function. Some schools are also equipped with adjustable seats. The existing adjustable height student seats are generally installed on the upper and lower brackets of the seat. The screw bolt accessories are used to adjust the height of the seat, turn the screw bolt, select the appropriate adjustment hole on the bracket, and then tighten the screw bolt to adjust the height of the seat, and the adjusted height has a step difference due to the interval of the adjustment hole , the height cannot be adjusted to a suitable height, the height of the seat cannot be adjusted arbitrarily within a certain range, and the seat cannot be rotated at multiple angles, which is time-consuming and laborious. Therefore, we propose a multi-degree-of-freedom student seat.

Utility model content

The purpose of this utility model is to provide a multi-degree-of-freedom student seat to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions: a multi-degree-of-freedom student seat, including a seat, the bottom of the seat is fixed with a fixed plate, and one side of the fixed plate is welded with a V-shaped elastic bracket , the other end of the V-shaped elastic bracket is fixed with a chair back, the bottom of the fixed plate is welded with a support rod, the support rod is inserted into the inner cavity of the adjustment rod, and the outer wall of the adjustment rod is inserted with a rotating shaft, One end of the rotating shaft is provided with an adjusting knob, the bottom of the adjusting rod is plugged into the inner cavity of the rotating shaft sleeve, an opening and closing button is inserted into the rotating shaft sleeve, and the outer wall of the rotating shaft sleeve is fixed with feet. The bottom of the leg is provided with a rubber pad, the outer wall of the support rod is provided with a threaded track, and the inner cavity of the adjustment rod is provided with a spiral steel bar matching the threaded track, and the spiral steel bar is welded on the top of the rotating platform , the bottom of the rotating platform is fixed with a driven gear, and the other end of the rotating shaft is welded with a driving gear that matches the driven gear, and the inner cavity of the rotating shaft sleeve is provided with a tangential limiting block, and the tangential limiting The bottom of the block is fixed with a bearing, and the other end of the opening and closing button is fixed with a limit stop by a pole.

Preferably, the section of the tangential stopper corresponds to the outer wall of the stopper.

Preferably, both the driven gear and the driving gear are bevel gears, and the conical surface of the driven gear is attached to the conical surface of the driving gear.

Preferably, there are three identical groups of legs, and each group of legs is arranged in a circular arrangement on the outer wall of the shaft sleeve.

Compared with the prior art, the beneficial effect of the utility model is that the multi-degree-of-freedom student seat can be adjusted at any height within a certain range, so that students can adjust to the seat they want when they are in class or after class Height, and can rotate 360 degrees arbitrarily, by turning the adjustment knob to drive the rotation of the rotating shaft, thereby driving the rotation of the driving gear, the driven gear that matches the driving gear rotates accordingly, and the spiral steel bar welded on the rotating platform rotates, When the spiral steel bar rotates in the threaded track, the support rod moves up and down accordingly to realize the height adjustment of the seat, and the tangent limit block in the shaft sleeve rotates with the rotation of the bearing to realize the rotation of the seat , to facilitate the communication between the students and the left and right students. When the seat needs to be kept from rotating, the opening and closing button is activated, and the limit stopper fits with the cut surface of the cut surface limit block. At this time, the rotation of the cut surface limit block is restricted. The rotation of the seat is prevented, the structure is simple, and the operation is convenient.
