Problems solved by technology

[0002] The environment of the oil tanker is harsh during transportation, and it is in a highly dangerous explosive gas environment. The explosion-proof requirements are high. The friction of the metal of the general mechanical lock is prone to static electricity, which is easy to cause accidents and cannot meet the needs of safe transportation.
Traditional door locks use micro motors to drive gears, chains and other intermediate components to drive the switch of the deadbolt. The structure is complex. The previous mechanical structure is fixed by means of exposed equipment, which is easily damaged by thieves. In addition, because the size of the deadbolt and the connecting rod is not fixed, Complicated installation

Abstract

The invention discloses a pneumatic lock. The pneumatic lock comprises a cylinder (1), a drive connecting rod (2), an upper driven connecting rod (3), a lower driven connecting rod (4), an upper bolt (5), a lower bolt (6) and a door plate (9), and is characterized in that: the upper driven connecting rod (3) is fixedly connected with the upper bolt (5); the lower driven connecting rod (4) is fixedly connected with the lower bolt (6); the door plate (9) is provided with a fixed pivot; one end of the cylinder (1) is connected with the fixed pivot while the other end of the cylinder (1) is movably connected with the drive connecting rod (2); a shaft (7) is fixedly arranged on the door plate (9); the middle part of the drive connecting rod (2) is connected with the shaft (7) moveably; the two ends of the drive connecting rod (2) are respectively connected with the upper driven connecting rod (3) and the lower driven connecting rod (4) moveably; and the drive connecting rod (2) drives the upper driven connecting rod (3) and the lower driven connecting rod (4) to move under the action of the cylinder (1). The pneumatic lock has a simple structure and high safety.

Description

technical field [0001] The invention relates to a special lock used in the anti-theft field, in particular to a special anti-theft pneumatic lock for the fuel tank door of an oil tanker. Background technique [0002] The environment of tank trucks is harsh during transportation, in a highly dangerous explosive gas environment, and the explosion-proof requirements are high. The friction of the metal of the general mechanical lock is prone to static electricity, which is easy to cause accidents and cannot meet the needs of safe transportation. Traditional door locks use micro motors to drive gears, chains and other intermediate components to drive the switch of the deadbolt. The structure is complex. The previous mechanical structure is fixed by means of exposed equipment, which is easily damaged by thieves. In addition, because the size of the deadbolt and the connecting rod is not fixed, It is more cumbersome to install. Contents of the invention [0003] The object of th...
