Embodiment 1

[0083] As shown in Fig. 1-Fig. 5 (D), a kind of public seat for stadiums includes a seat base 1, a seat support 2, a chair back 3, a chair back support 4, a connecting shaft 5 and a bracket 6; the seat base 1 Including seat surface 11, seat support connecting portion 12, chair back 3 includes seat back 31, seat back supporting connecting portion 32; Connection, the seat support connecting portion 12 and the seat support 2 are fixedly connected, the seat support 2 and the connecting shaft 5 are movably connected, and the seat 1 can be turned up. The seat 1 also includes seat hollow reinforcing ribs 13 , and the seat back also includes seat back hollow reinforcing ribs 33 .

[0084] The seat hollow reinforcing rib 13 is in the shape of an elbow, at the front edge of the seat surface 11 and the front part of both sides of the seat surface 11, the edge of the seat surface 11 is aligned with the outer side of the seat hollow reinforcing rib 13, and the seat hollow reinforcing rib 1...

Embodiment 2

[0087] Such as Figure 6 , Figure 7 As shown, the seat air injection hole 133 is at the end of the seat hollow reinforcing rib 13 on the right side of the seat 1; the seat overflow port 134 is at the end of the seat hollow reinforcing rib 13 on the left side of the seat surface 11 . The chair back air injection hole 333 is at the end of the chair back hollow reinforcing rib 33 on the right side of the chair back 31 ; the chair back overflow opening 334 is at the end of the chair back hollow reinforcing rib 33 on the left side of the chair back 31 . Others are the same as embodiment 1.

Embodiment 3

[0089] Such as Figure 8 As shown, the rib 13 is on the inner side of the edge in the seat, and the others are the same as in Embodiment 1.

Abstract

The invention relates to the plastic chairs and the fabrication field thereof, providing a gymnasium chair seat and back and a fabrication technology thereof. The invention breaks through the choke point of the prior art in the gymnasium chair fabrication, namely, the problems that the product has bad strength, the connection structure can not meet requirements, the material consumption is large, the cost is high, the material is easy to become old and split, the product is shrunk much and the molding size is hard to control; thereby, the invention provides a gymnasium chair seat and back and a fabrication technology thereof. The front half part of the chair back is a hollow reinforcing rib structure and two sides of the back half part are seat-back support structures; the edges of the chair seat and the chair back are provided with air injection holes and flash ports. The fabrication technology includes fabrication of material granules and gas-assist injection molding. The chair seat and the chair back of the product in the invention has the advantages of high strength, simple and compact structure, low cost, artistic appearance, comfort and environmental protection.

Description

technical field [0001] The invention relates to the field of plastic seats and its manufacture, and relates to a seat, a back of a stadium chair and a manufacturing process thereof. Background technique [0002] In recent years, with the rapid development of industry, especially the rapid development of polymer materials and mold technology, plastic seats are widely used in light industrial products because of their beautiful appearance, simple process and easy mass production. closely related. [0003] The seat and back of plastic public seats are mostly injection molding and blow molding, but each has its own advantages and disadvantages. Injection-molded seats can be made into complex structural parts but have edges in appearance. Blow-molded seats have a smooth appearance without edges and corners, but the product structure is a simple double-sided structure, and the molding is difficult to control. [0004] Public seats, especially stadium chairs, must meet the requir...
