Problems solved by technology

An obvious shortcoming of the lock is that the cylinder can be decompressed after the air circuit is cut off, the safety performance is low, and it is not suitable for application in the field of storage and transportation equipment. Pneumatic locks with high and low temperature and high stability have very important production and commercial value

Embodiment 1

[0032] Such as Figure 1-2 shown.

[0033] A semi-automatic pneumatic lock, comprising a lock case and a lock case cover; a lock pin 8 is arranged through the lock case; a cylinder 4 is arranged inside the lock case; a spring 14 is arranged at the top of the piston rod 5 of the cylinder 4 ; The piston rod 5 is fixedly connected with the lock pin 8 . The pneumatic lock of the present invention arranges the spring 14 on the top of the piston, and the inflated state is the unlocked state, even if the air circuit is cut off, it is still in the locked state, which has higher safety.

Embodiment 2

[0035] The semi-automatic pneumatic lock as described in Embodiment 1, the difference is that the semi-automatic pneumatic lock also includes a solenoid valve 12 and an air pressure sensor 1; the cylinder is provided with an air inlet 2 and an air outlet 3; The hole 2 communicates; the air pressure sensor 1 communicates with the air outlet 3 . The solenoid valve 12 inflates the cylinder through the air inlet 2, and the piston rod 5 retracts; after the gas is cut off, the gas is discharged from the cylinder through the solenoid valve 12; the spring 14 automatically ejects the piston rod 5 and the lock pin 8. The air pressure sensor 1 communicates with the cylinder through the air outlet 3 to realize real-time monitoring of the air pressure in the cylinder 4, and the remote control server adjusts the control command according to the air pressure state in the cylinder 4, which improves the accuracy and flexibility of the control.

Embodiment 3

[0037] The difference of the semi-automatic pneumatic lock as described in Embodiment 1 is that the cylinder 4 is a one-way cylinder. The one-way cylinder has simple structure and higher stability.

Abstract

The invention relates to a semiautomatic pneumatic lock and a working method thereof. The semiautomatic pneumatic lock comprises a lock shell and a lock shell cover. A lock pin penetrates the lock shell. An air cylinder is arranged in the lock shell. A spring is arranged at the top end of a piston rod of the air cylinder. The piston rod is fixedly connected with the lock pin. According to the semiautomatic pneumatic lock, the spring is arranged at the top of a piston, the air inflation state is the unlocking state, and the locked state is maintained even if the air way is cut off, so that safety is higher. The semiautomatic pneumatic lock is simple in structure, high in stability and high in safety; the semiautomatic pneumatic lock still can work normally under the serve conditions such as the extreme temperature and strong vibration.

Description

technical field [0001] The invention relates to a semi-automatic pneumatic lock and its working method, belonging to the technical field of automatic locks. Background technique [0002] At present, in the field of storage and transportation equipment, whether it is the door of vans, container doors, or valves for oil transportation tank trucks, electronic locks or electronic locks are mostly used in the process of authorization control and monitoring management (remote control server) of storage and transportation equipment. seal up. The electronic seal process is cumbersome and costly, and electronic locks are widely used; however, the service life of electronic locks is shortened due to harsh transportation conditions, such as bumpy cars and extreme temperatures on the road (-40°C to 80°C). , The failure rate of electronic locks is much higher than the normal use environment, which not only brings hidden dangers to the authorization control and monitoring remote control ...
