Roller shutter door capable of being quickly retracted and released

Abstract

The invention discloses a roller shutter door capable of being quickly retracted and released, and belongs to the technical field of roller shutter doors. The roller shutter door comprises door posts,a roller shutter door body, cross beams and smoke sensors; the cross beams are fixed at the tops of the two door posts correspondingly, storage grooves are formed in the upper parts of the interiorsof the door posts, guide holes penetrate through one sides of the storage grooves, material suction plates are mounted below the interiors of the storage grooves, and a conduction strip is fixed to one side of each material suction plate. The roller shutter door is provided with the guide holes, the storage grooves, the material suction plates and the conduction strips, in the using process of theroller shutter door, a user can inject lubricating oil into the guide holes regularly, the lubricating oil can be stored in the storage grooves, the material suction plates made of sponge can adsorbthe lubricating oil, so that the lubricating oil loss speed is decreased; and the multiple conduction strips fixed to the material suction plates can conduct the lubricating oil, so that the lubricating oil enters sliding rails by partition plates through the conduction strips, in the retracting and releasing process of the roller shutter door, the two sides of the roller shutter door can be fullylubricated in the process sliding in the sliding rails, and thus the two sides of the roller shutter door are not prone to abrasion.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a fast retractable rolling door. Background technique [0002] The rolling shutter door is a multi-joint movable door piece connected in series through the shaft. In a fixed slideway, the upper and lower doors are rotated around the reel above the door. It is suitable for public places such as commercial facades, garages, shopping malls, hospitals, factories and mines. Or residential, divided into ordinary rolling doors, windproof rolling doors and fireproof rolling doors from the use. [0003] According to the Chinese patent with the publication number CN210483489U, a fast opening and closing dust-proof rolling door is disclosed, including a motor, a control box for outputting to the motor to control the forward and reverse rotation of the output shaft of the motor, a rolling door body, and a door body. The opening height detection device, the optical fiber sensor used to...
