a fast door

Abstract

The present invention relates to the technical field of doors, in particular to a fast door, comprising a rollable door curtain, the upper end of the door curtain is fixed on a roller, the left and right sides of the door curtain are provided with tracks extending vertically up and down, and the track includes a The fixed connection plate for the fixed connection of the building body and the front track outer plate and the rear track outer plate which are respectively fixedly connected with the front and rear ends of the fixed connection plate and extend vertically towards the curtain side, the front track outer plate and the rear track outer plate respectively have The front arc-shaped arched buffer portion arched forward and the rear arc-shaped arched buffer portion arched backward, the front and rear intervals between the front track outer plate and the rear track outer plate form a guide section for guiding the door curtain, and the door curtain It is a flexible material door curtain, and the door curtain is provided with reinforced protective strips extending along the left and right directions, and the ends of the left and right ends of the reinforced protective strips are provided with guiding devices that can act on the guiding section. The structure is firm and stable, not easy to damage, good pressure resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of doors, in particular to a fast door. Background technique [0002] Existing high-speed doors are often used frequently as access channels for industrial production, and the incidence rate of sudden impact by vehicles and heavy objects is relatively high, which will cause the door curtain to collide with the door curtain track under the action of the momentum and damage it. The door curtain tends to detach from the track and apply force to the track, thereby causing damage to the track, high maintenance costs, short service life, and weak pressure resistance such as wind pressure. Contents of the invention [0003] An object of the present invention is to provide a fast door with firm and stable structure, not easy to be damaged, good pressure resistance and long service life. [0004] The above-mentioned technical purpose of the present invention is achieved by the following technical solutions: a high...
