Bidirectional anti-explosion folding pneumatic retractable door

Abstract

The invention relates to a retractable door, in particular to a bidirectional anti-explosion folding pneumatic retractable door. The bidirectional anti-explosion folding pneumatic retractable door comprises two groups of retractable door structures; each group of retractable door structures comprises a door box and a plurality of doorframes; each retractable door structure also comprises a rubber airbag and an electric air pump; an air port of each rubber airbag is communicated with an air port of the corresponding electric air pump; the rubber airbag is of a wave shape in the length direction of the rubber airbag; a soft steel wire which is distributed in a ring shape along the bag wall and extends along the length direction of the rubber airbag is embedded into the bag wall of each rubber airbag; the plurality of doorframes are fixed on the corresponding rubber airbags and are arranged at intervals in the length direction of the rubber airbags; each doorframe comprises a first doorframe and a second doorframe which are symmetrically arranged and are respectively fixed at both sides of the rubber airbag; a strip roller is arranged between the bottom end of each first doorframe and the bottom end of the corresponding second doorframe.

Description

technical field [0001] The invention relates to a retractable door, in particular to a two-way explosion-proof folding pneumatic retractable door. Background technique [0002] At present, most enterprises and institutions and public places (including a small number of personal villas) have portal devices, and many portal devices use retractable doors. [0003] The telescopic door mainly comprises a door box and a door frame. The telescopic doors of the prior art all drive the rollers arranged at the bottom of the door box through a motor to open and close the entire telescopic door. But the retractable door of this structure has the following disadvantages: [0004] 1. The structure of the retractable door with this structure is relatively complex, with more consumables and higher maintenance costs; [0005] 2. It is not suitable for frequent full-load actions and has a short service life; [0006] 3. The speed of electric components is generally fixed, and it is not eas...
