Description

A fast door structure

technical field

The invention relates to the technical field of doors, in particular to a fast door structure.

Background technique

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

An object of the present invention is to provide a fast door structure with firm and stable structure, not easily damaged, good pressure resistance and long service life.

The technical purpose of the present invention is achieved through the following technical solutions: a fast door structure, including a rollable door curtain, the upper end of the door curtain is fixed on the roller set near the top of the door, the left and right sides of the door curtain The side is provided with a track extending vertically up and down, and the track includes a fixed connection plate that is fixedly connected with the building body and a fixed connection plate that is fixedly connected with the front and rear ends of the fixed connection plate and extends vertically toward the side of the door curtain. The front track outer panel and the rear track outer panel respectively have a front arc-shaped arched buffer portion arched forward and a 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 guiding section for guiding the door curtain, the door curtain is a flexible material door curtain, and the door curtain is provided with a set extending along the left and right direction The reinforced protective strip, the ends of the left and right ends of the reinforced protective strip are provided with guiding devices that can act on the guide section, and the guiding device includes an annular jacket installed on the end of the reinforced protective strip, located in the annular The annular inner sleeve in the outer sleeve, the buffering direction change spring connected between the annular outer sleeve and the annular inner sleeve, the connecting rod installed in the annular inner sleeve, and the connecting rod is fixed at one end of the guide section There are spherical protrusions acting on the guide section.

In the above technical solution, the entire structure has good integrity, high structural strength and stable operation, is not easy to be damaged, has good pressure resistance and long service life. Good guidance is stretching between the upper and lower sides, and when the door curtain is impacted, in the case of deformation of the door curtain, by strengthening the role of the protective strip and the guiding device, and arching the buffer part in the front arc and arching in the rear arc With the function of the buffer part, the door curtain can form a temporary buffer and shrink upward. Using this guide section can not only reduce the buffer force, but also reduce the damage rate of the door curtain and the damage rate of the track.

As a preference for the present invention, the front track outer plate has a plurality of front arc-shaped arched buffers arranged at intervals up and down, and the rear track outer plate has a plurality of rear arc-shaped arched buffers arranged at intervals up and down. The number of buffering parts and the rear arc arched buffering parts are equal and correspond to each other in the horizontal left and right directions. It is not only beneficial to the smooth use of the fast door, but also can effectively protect the door curtain and track, reduce the damage rate and improve the pressure resistance.

As a preference for the present invention, there are a plurality of reinforcing protective strips arranged at intervals up and down. Improving the ductility and strength of the door curtain is not only conducive to the smooth use of the high-speed door, but also can effectively protect the door curtain and track, reduce the damage rate, and improve the pressure resistance.

As a preference for the present invention, the spacing distance between two adjacent reinforcing protection strips is greater than the spacing distance between two adjacent front arc-shaped arch buffers or greater than the interval between adjacent two rear arc-shaped arch buffers distance between sections. It is not only beneficial to the smooth use of the fast door, but also can effectively protect the door curtain and track, reduce the damage rate and improve the pressure resistance.

As a preference for the present invention, the number of reinforcing protection strips is smaller than the number of front arc-shaped arched buffers on the same track or the number of rear arc-shaped arched buffers on the same track. The force distribution is better, which is not only conducive to the smooth use of the fast door, but also can effectively protect the door curtain and track, reduce the damage rate, and improve the pressure resistance.

As a preference for the present invention, the position where the front track outer plate is located between two adjacent front arc-shaped arched buffers and the position where the rear track outer plate is located between two adjacent rear arc-shaped arched buffers is upright department. The force distribution is better, which is not only conducive to the smooth use of the fast door, but also can effectively protect the door curtain and track, reduce the damage rate, and improve the pressure resistance.

As a preference for the present invention, the upright portion is provided with a guiding arc-shaped projection facing the guiding section for anti-collision deceleration buffering. It can effectively protect the door curtain and track, reduce the damage rate and improve the pressure resistance.

As a preference for the present invention, the fixed connecting plate, the front track outer plate and the rear track outer plate are all hard material plates, and a flexible buffer protection film is provided on the side plate near the guide section. It can effectively protect the door curtain and track, reduce the damage rate and improve the pressure resistance.

As a preference of the present invention, the anti-collision deceleration buffer guiding arc-shaped protrusion is a rubber body. It can effectively protect the door curtain and track, reduce the damage rate and improve the pressure resistance.

As a preference for the present invention, three buffering direction-changing springs are arranged between the annular outer sleeve and the annular inner sleeve and are distributed in the shape of a regular triangle. It can effectively protect the door curtain and track, reduce the damage rate and improve the pressure resistance.

The beneficial effect of the invention is that the whole structure has good integrity, excellent force distribution, high structural strength and stable operation, is not easy to be damaged, has good pressure resistance and long service life.
