Problems solved by technology

[0002] At present, the seat surface and backrest of many chairs on the market are made of wood or wooden plywood, without edge sealing treatment, after a period of use, due to the influence of external temperature and humidity Expansion openings or cracks appear, and some edge bandings are mostly stitched along the periphery with iron sheets, plastics, wooden strips, etc. The manufacturing process is rough, and the joints often scratch the clothes, and the edge banding is easy to fall off, which affects the use and safety of the chair. beautiful
It needs multiple repairs to restore the original state, so it brings a lot of trouble to the user

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.

Description

technical field [0001] The invention relates to a chair, in particular to a chair with an injection molding edge sealing structure. Background technique [0002] At present, the seat surface and backrest of many chairs on the market are made of wood or wooden plywood, without edge sealing treatment, after a period of use, due to the influence of external temperature and humidity Expansion openings or cracks appear, and some edge bandings are mostly stitched along the periphery with iron sheets, plastics, wooden strips, etc. The manufacturing process is rough, and the joints often scratch the clothes, and the edge banding is easy to fall off, which affects the use and safety of the chair. beautiful. Need repeatedly maintenance just can restore original state, therefore, has brought very big trouble to the user. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a chair with an injection-molded edge-sealing structur...
