Workshop door bottom sealing device

Abstract

The invention discloses a workshop door bottom sealing device and relates to the field of dust-proof sealing. The workshop door bottom sealing device comprises a fixing assembly, a speed reducer assembly, a rotating assembly and a rubber sealing assembly, wherein the fixing assembly is fixed to a sealed element, the speed reducer assembly comprises a worm and gear speed reducer, the worm and gear speed reducer is fixed to the sealed element through the fixing assembly, and a driving device is further arranged on the worm and gear speed reducer. The rotating assembly comprises a drive shaft and at least one rotating arm, wherein the rotating arms are fixed to the drive shaft, the drive shaft is connected with the worm and gear speed reducer, and the worm and gear speed reducer drives the drive shaft to rotate. One end of the rubber sealing assembly is fixed to the lower end of the sealed element, the other end of the rubber sealing assembly is fixed to the rotating arms, and the rotating arms drive the rubber sealing assembly to move. The workshop door bottom sealing device can achieve self locking, can be easily operated by a single person and is simple in structure and reliable in sealing.

Description

Technical field [0001] The invention relates to the field of dustproof sealing, in particular to a sealing device for the bottom of a workshop door. Background technique [0002] With the development of my country’s industry, the requirements for dust-proof sealing in heavy equipment assembly workshops are getting higher and higher, and the number of opening and closing of the movable doors in the workshop is increasing. In order to play a role of dust-proof sealing, sealing equipment is usually installed on the movable doors. The bottom of the door, in order to achieve the role of sealing the gap between the movable door and the ground. [0003] In order to solve the above problems, Chinese utility model CN2625544Y discloses a built-in lifting type automatic door bottom sealing strip, including a shell, upper sliding block, lower guide block, curved spring, front top block, rear top block, sealing pressure plate, and flexible sealing strip , Drive components. The flexible sealing...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned built-in lift-type door bottom automatic sealing strip can realize the function of dust-proof sealing to a certain extent, its structure is very complicated and the operation is inconvenient.

[0005] In addition, because the sealing equipment in the heavy equipment assembly workshop is generally very heavy, when switching from the closed state to the open state, using a motor to drive will increase the cost of the equipment, and driving it manually will face the problem of too much work intensity

At the same time, due to the self-weight of the sealing device, after the drive is stopped, the sealing device will automatically press down and re-seal under the action of gravity, which increases the workload when opening. In order to solve this problem, an additional locking mechanism is usually set up, which further increases equipment cost
