Abstract

The invention discloses a chair with an injection edge sealing structure, comprising a seat. The edges of the seat are manufactured into rectangular or wedge-shaped convex bodies. The convex bodies extend along the periphery of the whole seat and are packaged by the sealed edges formed by one-time whole die injection by a plastic injection process. Height adjusting plates are connected at the two sides of the seat, which can properly adjust the height of the chair. The seat and the back utilize the injection edge sealing process. The chair is novel in structure, beautiful in appearance, waterproof and durable. The chair is especially suitable for the places for teaching, working and entertainment.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.

Fig. 1 is to Figure 2 shows that structural representation of the present invention.

Reference numeral wherein is: chair pin 1, fixing hole 1a, connecting rod 12, Protective foot muff 11, seat 2, installing hole 2b, DOCK LEVELER 3, adjusting portion 31, adjustment hole 31a, connecting portion 32, connecting hole 32b, seat back rest frame 4, pilot hole 4b, head protector 41, backrest 5, convex body 6, edge sealing 7.

Shown in Fig. 1 to Fig. 4 b, a kind of chair of the present invention with injection edge sealing structure, the periphery of seat 2 is shaped on the convex body 6 that geometry is rectangle or wedge shape, the edge sealing 7 of seat periphery is plastics, it is that at first seat 2 is put into the plastics that will be heated to molten condition behind the specific mould to import pressing mold of mould injection molded, and convex body 6 is packaged by plastics edge sealing 7.By the seat 2 of injection edge sealing, not only specious novelty but also sturdy and durable, waterproof, protection against the tide.The convex body 6 of present embodiment is rectangular.

Shown in Fig. 5 to Fig. 8 b, the lower surface left and right sides of seat 2 is symmetrically arranged with DOCK LEVELER 3, and DOCK LEVELER 3 is a swallow-tail form wide at the top and narrow at the bottom, can certainly be designed to other shape as required, and DOCK LEVELER 3 is shaped on adjusting portion 31 and connecting portion 32.Connecting portion 32 is shaped on connecting hole 32b, and the bottom surface of connecting portion 32 is equipped with seat back rest frame 4, and seat back rest frame 4 is the U-shaped steel pipe, and itself and connecting hole 32b corresponding section are shaped on pilot hole 4b, and seat 2 is shaped on installing hole 2b with connecting hole 32b corresponding section.Installing hole 2b, connecting hole 32b fix with securing member in order with pilot hole 4b is corresponding during installation.
