A door lock locking device with improved structure

Abstract

The invention provides a sterilizer door lock locking device with an improved structure, belonging to the technical field of disinfection equipment. It solves the problem of poor security of existing sterilizer door locks. The sterilizer door lock locking device of the improved structure includes a box door and a positioning seat installed on the box body. A door sliding rod capable of axial movement is pierced in the box door, and a perforation is opened on the positioning seat, and the door sliding rod can move. Axial movement to the perforation of the positioning seat, a locking rod that can limit the axial movement of the door sliding rod is pierced in the positioning seat, a Hall sensor is installed on the outer wall of the positioning seat, and a motor and an electrical connection with the motor are installed in the box. The travel switch connected and in the normally closed state, the motor shaft is connected with the locking lever, and a pneumatic lock connected to the pressure vessel in the box is installed on the side of the travel switch, and the pneumatic lock can be activated when the pot is in a state of high pressure Travel switch and make the travel switch in normally open state. The invention has the advantages of high safety and good locking effect.

Description

technical field [0001] The invention belongs to the technical field of disinfection equipment, and in particular relates to a sterilizer door lock locking device with an improved structure. Background technique [0002] The sterilizer is designed by taking advantage of the fact that bacteria cannot survive under high temperature and high pressure, and is used to kill bacteria in items. The sterilizer is an ideal disinfection equipment. It is suitable for medical and health undertakings, scientific research undertakings, agriculture and other units. It can sterilize and sterilize medical equipment, glassware, solution culture medium and other items. necessary testing equipment. [0003] The sterilizers in the existing market generally adopt the moist heat sterilization method. Compared with other sterilization methods, the moist heat sterilization method has the advantages of easier protein denaturation, strong penetrating power, and enhanced heat energy release when steam t...

Problems solved by technology

However, the pressure inside the pressure vessel of this method is relatively high, so the requirements for the sealing performance of the sterilizer door lock are very high. If the sealing performance is not good, the sterilization effect may not be obvious, and bacteria will remain, which will endanger human health.

[0004] Most of the existing door locks use rotary door locks. Although this kind of door locks are simple to operate and beautiful in appearance, these door locks do not use self-locking devices. If the pressure is too high, operator errors or mechanical failures will cause pressure. The door of the container is accidentally opened, causing the contents of the pressure container to rush out, which will cause loss of personnel and property, and most door lock devices are driven by air pressure. The air pressure system needs regular maintenance and cleaning to ensure the normal operation of the air pressure system. Complex structure, cumbersome maintenance
