Problems solved by technology

The disadvantages of this sealing structure are: 1. The width of the door sealing flange is wider, which not only increases the cost, but also makes the line of the blowing hole longer, which increases the difficulty of punching—it is easy to miss when punching; 2. Since the door sealing flange is welded on the end face of the cylinder, the welding is difficult, and the deformation is large, which affects the flatness of the sealing surface

Abstract

The invention discloses a sealing structure of a vertical lift quick opening door, which can reduce the cost, the welding difficulty and the punching difficulty and improve the planeness of a sealingsurface. The sealing structure comprises a door baffle, a cylinder body as well as a door sealing flange and a reinforcing groove strip which are fixed on the outer surface of the cylinder body; wherein a loop-locked sealing groove is arranged at the side where the front of the door sealing flange faces to the door; a sealing strip is embedded inside the sealing groove; the door baffle is fixed onthe reinforcing groove strip by a fixing bolt; the wall thickness of the door sealing flange is less than or equal to 30mm, and the width thereof is less than or equal to 33mm; and the door sealing flange is also internally provided with a vent pipe communicated with the sealing groove. The sealing structure can be widely applied to medium-small sterilization equipment.

Description

technical field [0001] The invention relates to a vertical lifting quick opening door, in particular to a sealing structure of a vertical lifting quick opening door. Background technique [0002] At present, domestic medical sterilization equipment manufacturers usually use cog-type motorized doors for the transmission mechanism of the lift-type quick-opening doors. Such as figure 1 As shown, the sealing structure of the cog-type motorized door includes: the door sealing flange 2 welded on the end surface of the cylinder body 1 and the reinforcing groove bar 4 welded on the outer surface of the cylinder body, in order to increase the rigidity of the door sealing flange 2 and strength, the wall thickness of the door sealing flange 2 is usually between 25 and 30 mm, and the width of the door sealing flange 2 is relatively wide—its outer surface exceeds the reinforcement groove 4 a lot, and the front of the door sealing flange 2 is opposite to A closed-loop sealing groove is ...
