Summary of the invention

Technical problem to be solved by this invention provides a kind of seat with height adjusting structure, have highly easy to adjust, simple in structure, good stability, advantage such as it is attractive in appearance to have a fashion style.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of seat with height adjusting structure comprises chair pin and seat with two support portions.The support portion is shaped on two at least and is the fixing hole of arranging up and down, is fitted with DOCK LEVELER between seat and the support portion.Be shaped on adjusting portion and connecting portion on the DOCK LEVELER respectively, adjusting portion is shaped at least two and is the adjustment hole of arranging up and down, and the adjustment hole on the adjusting portion cooperates with the seat respective face with the corresponding installation of support portion fixing hole, the end face of connecting portion.

The technical measures of being taked also comprise:

Above-mentioned connecting portion is shaped on connecting hole, and the corresponding position of seat and connecting hole is shaped on installing hole; Bottom surface at connecting portion is fitted with seat back rest frame, and the corresponding position of seat back rest frame and connecting hole is shaped on pilot hole.The pilot hole of installing hole, connecting hole and seat back rest frame is stacked successively to be matchedly connected.

Above-mentioned seat back rest frame has a upwardly extending open end, also is being fitted with backrest near the open end place.

The edge of above-mentioned backrest is shaped on the convex body of rectangle or wedge shape, and described convex body extends along the periphery of whole backrest, and convex body is packaged by the injection molded edge sealing of pressing mold of plastic monoblock.

The edge of above-mentioned seat is shaped on the convex body of rectangle or wedge shape, and described convex body extends along the periphery of whole seat, and convex body is packaged by the injection molded edge sealing of pressing mold of plastic monoblock.Seat, backrest adopt injection edge sealing technology, not only good looking appearance but also waterproof durable.

Above-mentioned DOCK LEVELER is a swallow-tail form wide at the top and narrow at the bottom, makes seat look novelty more attractive in appearance.

Above-mentioned chair pin adopts sheet metal to be processed into oval hollow pipe and makes, and seat back rest frame adopts steel pipe to make, and the weight that the intensity that promptly can strengthen seat alleviates seat can increase aesthetic feeling again

The end of above-mentioned chair pin adds Protective foot muff, and Protective foot muff can play the wearing and tearing that reduce the chair pin and reduce the noise that moves with the ground generation with thin-skinned contact the in ground.

The open end end of above-mentioned seat back rest frame is set with head protector, installs head protector additional and can make outside the open end end can not be exposed to, and has effectively protected port and has avoided the user by the unexpected risk that scratches of port.。

Compared with prior art, the present invention increases height-adjustable DOCK LEVELER, make adjusting more convenient, and reduced the stability problem of body because of boring a hole and too much bringing, seat and backrest adopt plastic injection-moulded edge sealing process, make seat overall structure exquisiteness, novel and beautiful and waterproof durable are specially adapted to places such as teaching, office, amusement and use.
