Anti-falling air circuit-breaker installation box

Abstract

The invention discloses an anti-shedding air circuit-breaker installation box. The anti-shedding air circuit-breaker installation box comprises a casing, one side of the inner wall of the casing is fixedly connected with a rectangular pipe, the bottom of the rectangular pipe is provided with a first through groove, the rectangular pipe is internally slidably connected with a toothed bar, and one end of the toothed bar passes through the rectangular pipe and is fixedly connected with one side of a first clamping plate. According to the invention, an air circuit-breaker is installed through arrangement of the casing, through cooperation among the rectangular pipe, the first through groove, the toothed bar, a latch, a rotating rod and a gear, a rotation knob is rotated to drive the first clamping plate to perform left-to-right movement, the air circuit-breaker is clamped by moving the first clamping plate to the left and to the right for cooperation with the fixation plate, through cooperation among a threaded rod, a nut, a second through groove and a connecting rod, a handle is rotated to drive a second clamping plate to move up and down, the air circuit-breaker is clamped and does not shake by moving the second clamping plate up and down for cooperation with a fixation block, and thus the effects of conveniently installing and clamping the air circuit-breaker are realized.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an anti-dropping air circuit breaker installation box. Background technique [0002] The air circuit breaker is a kind of circuit breaker installed in the circuit to protect the circuit. It is often used in household electricity. When the current in the circuit exceeds the rated current or the circuit is short-circuited, the air switch will automatically break. Open to prevent damage to the circuit caused by excessive current, or fire caused by excessive temperature caused by short circuit. The air circuit breakers on the market are generally installed in the installation box to protect it and prevent children from touching the air. The wires on the circuit breaker cause electric shock, but the mounting box on the market currently has poor fixtures, and it often happens that the air circuit breaker falls off and the air circuit breaker is disconnected from the househ...

When the current in the circuit exceeds the rated current, or when the circuit is short-circuited, the air switch will automatically break. Open, to prevent damage to the circuit caused by excessive current, or fire caused by excessive temperature caused by short circuit. The air circuit breakers on the market are generally installed in the installation box to protect it and prevent children from touching the air. The wires on the circuit breaker cause an electric shock, but the fixing device of the installation box on the market is poor, and it often happens that the air circuit breaker falls off, causing the air circuit breaker to be separated from the household circuit, resulting in a power outage
