Workshop sealing door

Abstract

The invention relates to a workshop sealing door which comprises a door body. The door body is arranged outside a door frame arranged on an entrance of a workshop. Guide wheel devices used for the door body to linearly move are arranged on the upper portion and the lower portion of the door frame. Door frame sealing rubber strips are arranged on the periphery of the outer side of the door frame, door body sealing rubber strips corresponding to the door frame sealing rubber strips are arranged on the periphery of the inner side of the door body, the door frame sealing rubber strips are installed in grooves in the door frame, an air bag is arranged in the groove and located behind the door frame sealing rubber strips, and the air bag is fixed to the door frame sealing rubber strips by means of a rigid connection flat plate. One side of the door frame is provided with a photoelectric detection switch used for detecting whether the door body is in a preset closing position, the photoelectric detection switch is connected with a controller, and the controller is connected with and controls an inflation valve used for inflating the air bag. According to the door, the door body sealing rubber strips and the door frame sealing rubber strips cannot rub one another in a sliding mode, the service life of the rubber strips is prolonged, and the peripheral sealing effect is good.

Description

technical field [0001] The invention belongs to the technical field of workshop doors, and in particular relates to a workshop airtight door. Background technique [0002] The workshop door is designed to meet the needs of industries such as food, pharmaceuticals, electronics, printing, textiles, cigarettes, etc. to keep the workshops and packaging workshops clean, prevent the loss of cold air, and isolate areas from other industrial workshops. Especially for factories with high requirements for heat preservation and cleanliness, the industrial automatic door used must be a fast, safe and reliable door, and the performance of the door plays a very key role in it. An airtight door is disclosed in the prior art. The door body covers the door frame at the door of a controlled-atmosphere warehouse. Between the door body and the first plane door frame, between the door body and the second plane door frame on the ground, inflatable airbags and sealing strips are arranged in seque...

AI Technical Summary

Problems solved by technology

Although this kind of airtight door can realize the contact between the door body and the first and second plane door frames of the door frame of the controlled atmosphere warehouse, and achieve sealing through the inflated air bag and the sealing strip, this sealing structure will cause damage to the rubber strip during long-term use. Easy, especially the rubber strip that is in contact with the door frame of the second plane on the ground, friction with the door frame for a long time, is more likely to be damaged, and affects the sealing effect
