Electric lock

Abstract

The invention relates to an electric lock comprising an electric pull rod (1), a driving 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 panel (9), wherein the upper driven connecting rod (3) and the upper bolt (5) are fixedly connected; the lower driven connecting rod (4) and the lower bolt (6) are fixedly connected; a fixed pivot is arranged on the door panel (9); one end of the electric pull rod (1) is connected with the fixed pivot, and the other end of the electric pull rod (1) is movably connected with the driving connecting rod (2); a shaft (7) is fixedly arranged on the door panel (9); the middle part of the driving connecting rod (2) is movably connected with the shaft (7); both ends of the driving connecting rod (2) are respectively and movably connected with the upper driven connecting rod (3) and the lower driven connecting rod (4); and the driving connecting rod (2) drives the upper driven connecting rod (3) and the lower driven connecting rod (4) to move under the action of the electric pull rod (1). The invention has the advantages of simple structure and good 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 electric 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 electric 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 easy to be damaged by thieves. In addition, the size of the deadbolt and the connecting rod is not fixed. , It is more complicated to install. Contents of the invention The object of t...

[0002] The environment of the oil tank truck is harsh during transportation, in a highly dangerous explosive gas environment, and the explosion-proof requirements are high. The friction of the general mechanical lock metal is prone to static electricity, which is easy to cause accidents and cannot meet the needs of safe transportation.

Traditional electric 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 easy to be damaged by thieves. In addition, the size of the deadbolt and the connecting rod is not fixed. , it is more cumbersome to install
