Shaftless sealing door locking device

Abstract

The invention discloses a shaftless sealing door locking device which comprises a drive wheel, a tightening wheel, a transmission shaft, a tightening handle, a machine claw, a non-return spring sheet, a tightening rack, an upper enclosure and a lower enclosure, wherein the transmission shaft is arranged in an enclosure formed by the upper enclosure and the lower enclosure; the drive wheel and the tightening wheel are arranged on the transmission shaft; the tightening handle is arranged on a fixed base through a shaft, the upper end of the tightening handle is connected with the machine claw, and the machine claw is engaged with the drive wheel; the fixed base is fixed on a door; one end of the tightening rack is engaged with the tightening wheel, and the other end of the tightening rack is fixedly connected with the door; one end of the non-return spring sheet is fixed on the enclosure, the other end of the non-return spring sheet can be inserted into the drive wheel when the drive wheel reversely rotates to prevent the drive wheel from reversely rotating. The shaftless sealing door locking device disclosed by the invention has the benefits of compact structure, easiness in operation, reliability in locking, and no maintenance after repeated use; the sealing effect of the door is improved while the great convenience is brought to the repair and the maintenance of a harmful gas absorbing device.

Description

technical field [0001] The invention relates to a design technology of a locking device, in particular to the technical field of locking of a shaftless sealed door. Background technique [0002] With the rapid development of the organic synthesis industry and the petrochemical industry, more and more organic compounds enter the atmosphere. These substances often have a foul smell, which not only stimulates the senses, but also has a certain toxicity. The stench of pollution pollutes urban residents, making people feel unhappy, nausea, headache and loss of appetite, and it is easy to induce many diseases, which seriously affects the normal work and life of nearby residents. The masses are increasingly reacting to this. Therefore, the comprehensive prevention and control of air pollutants has become an urgent problem to be solved. [0003] With the control of air pollution, various treatment methods are adopted, such as catalytic oxidation method, activated carbon adsorption ...

AI Technical Summary

Problems solved by technology

These forms have some shortcomings. For example, the door buckle type is easy to release with the vibration of the equipment, the bolt type is easy to slip and buckle, and the number of bolts is large, the seal deformation is uneven, and the air leakage is large. Although the plug type is reliable, the sealing effect is poor
