Fireproof roller shutter door with high safety

Abstract

The invention discloses a fireproof roller shutter door with high safety. The roller shutter door comprises a wall body, a shell, a rotating shaft, spring shells, volute spiral springs, a door plate,slide blocks, a protection strip, a U-shaped plate, a clamping plate, a threaded rod, a rotary knob and a T-shaped block. One side of the wall body is fixed with the shell. The bottom of the shell isopened. The rotating shaft is fixed in the shell. The two ends of the rotating shaft are symmetrically and rotatably connected to the spring shells through bearings. The volute spiral springs are arranged on the inner walls of the spring shells. One end of each volute spiral spring is fixedly connected to the rotating shaft and the other end of each volute spiral spring is fixedly connected to each spring shell. The outer sides of the two spring shells on the rotating shaft are fixed with the door plate. The two sides of the door plate are equidistantly fixed with the slide blocks. The two adjacent slide blocks on the door plate are rotatably connected through a hinge. One end of the door plate, which is far away from the spring shells, is fixed with the protection strip. By using the fireproof roller shutter door with high safety, the probability of the door plate which is being damaged by high winds can be reduced, the safety is increased, construction is simple, cost is low and people can conveniently use the fireproof roller shutter door.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a fireproof rolling door with high safety. Background technique [0002] The rolling shutter door is made of multi-joint movable door pieces connected in series. In the fixed slideway, the upper and lower doors are rotated around the reel above the door. Rolling shutter doors are usually widely used in shops, but the door panels of the existing rolling doors are relatively soft. In the case of strong winds, the door panels are easy to bend, thereby detaching from the track, and the door panels are damaged. The safety is low, and the existing The structure of the rolling shutter door is complex and the cost is relatively high. For this reason, we propose a fireproof rolling shutter door with high safety. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a fireproof rolling door with simple...
