A tamper-proof lock for electric meter box

Abstract

The invention discloses an electric meter box burglary resistant lock. The electric meter box burglary resistant lock comprises a lock hole and a locking plate which is rotationally arranged on the inner side of a box door of an electric meter box, wherein the lock hole is fixedly formed in the outer side of the box door of the electric meter box, and the lock hole and the locking plate are located on two corresponding sides of the box door and the electric meter box. The electric meter box burglary resistant lock further comprises a rotary shaft, a lock catch and a spring bolt, wherein the rotary shaft can rotate around the axial direction of the rotary shaft itself, the lock catch is fixedly arranged on the rotary shaft, the spring bolt is fixedly arranged in the electric meter box and can be buckled by the lock catch in a matched mode, the rotary shaft penetrates through a shaft sleeve which is fixedly connected to the inner side of the box door of the electric meter box, the rotary shaft is fixedly provided with a connection part, the connection part can be driven by the locking plate and drive the rotary shaft to axially rotate around the connection part, an elastic part and a limiting part are arranged between the rotary shaft and the box door of the electric meter box, the elastic part is used for returning the rotary shaft, and the limiting part is used for limiting rotation of the rotary shaft. When the box door of the electric meter box is in an opened or locked state, the included angle between the lock catch and the box door of the electric meter box and the included angle between the connection part and the box door of the electric meter box respectively range from 0 degree to 90 degrees. The electric meter box burglary resistant lock is simple in structure, good in safety and not prone to burglary.

Description

technical field [0001] The invention relates to a tamper-resistant lock for an electric meter box. Background technique [0002] The existing electric meter box door lock, the lock cylinder and the lock tongue are crude, the fit is not tight enough, and it is easy to fall off and loosen.
