Notice No. CN 206621054U's a student uses stool, the effort has been made to this, make the effect that the second gear drove the rotation of first column spinner through first gear, it is rotatory that rethread first column spinner drives first screw rod and second screw rod, first screw rod is rotatory to make first sliding block drive first connecting rod erect, the second screw rod is rotatory to make the second sliding block drive the effect that the second connecting rod erects, finally through first connecting rod, the second connecting rod, the cooperation of lifter plate and connecting rod, it sticks up the effect that makes the lifter plate move the connecting rod to rise to have reached first connecting rod and second connecting rod, and easy operation, the student can adjust the height of stool according to the height, the learning efficiency when having improved the student and having gone up class. However, the device controller is located at the lower end of the device, needs to bend down when adjusting the height each time, and is high in cost and single in function due to the adoption of an electric mode, so that improvement is needed.

Disclosure of Invention

The utility model aims at overcoming above-mentioned technical shortcoming and providing a height-adjustable's student's seat, the utility model has the advantages of reasonable design, through the cooperation of elevating gear, first base and second base box structure, both realized the device's lift and enlarged the storage space again.

The utility model provides a technical scheme that technical problem adopted does: a height-adjustable student chair comprises a first base, supporting legs, a second base and a lifting device, wherein the first base and the second base are of a hollow box body structure with an opening at the front end and are convenient to store, a first open slot is formed in the upper end face of the first base, the second base is clamped in the first open slot, a first groove is formed in the middle of the left end and the right end of the second base, a rack is fixedly connected in the first groove, the lifting device comprises two rotating shafts, gears, first through holes, movable blocks, springs, hanging ropes and fixed rods, the rotating shafts are inserted in the second open slots at the left end and the right end of the first base, the gears are fixedly connected in the middle of the rotating shafts, the gears are meshed with the racks, a second groove is formed in the middle of the lower end of the second open slot, the movable blocks are clamped in the second groove, the lower end of each movable block is fixedly connected with the bottom of the second groove through the springs, and the first through holes are, both ends are equipped with the second through-hole that suits and first base lower extreme rigid coupling has a string rope about first base in first through-hole corresponding position, the other end rigid coupling of hanging the rope has dead lever and dead lever to pass the second through-hole and peg graft in first through-hole, and the fixed after the altitude mixture control of being convenient for, four edges and corners of terminal surface rigid coupling have 4 supporting legs under the first base.

Further, rack right-hand member and second base right-hand member face parallel and level realize the regulation of the device height with the gear looks meshing on the one hand, and on the other hand avoids producing the motion with first base and interferes.

The utility model discloses the beneficial effect who has is: the utility model has the advantages of reasonable design, through the cooperation of elevating gear, first base and second base box structure, both realized the device's lift and enlarged the storage space, had good development prospect.
