Technical Field

The invention relates to a protection structure for a circuit breaker and a using method thereof.

Background

The circuit breaker is a switching device capable of closing, bearing and breaking a current under a normal circuit condition and closing, bearing and breaking a current under an abnormal circuit condition, protects a power line and electrical equipment, and automatically breaks a circuit when serious overload or short circuit, undervoltage and other faults occur, and the circuit breaker has a function equivalent to a combination of a fuse type switch, an over-and-under-heat relay and the like. Domestic miniature circuit breaker need manual switching-on operation after automatic power failure, but present domestic circuit breaker generally does not take the protection casing, causes the mistake to electrocute when carrying out switching-on operation easily, has the potential safety hazard, and domestic miniature circuit breaker is direct placing mostly in the block terminal, does not set up the protective structure to the circuit breaker, if have more dust when wafting to the inside of circuit breaker, can make the life of circuit breaker reduce.

Disclosure of Invention

the invention improves the problems, namely the invention aims to provide a protection structure for a circuit breaker and a protection method thereof, and the protection structure is simple and safe.

The specific embodiment of the invention is as follows: the utility model provides a protective structure for circuit breaker, is including the handle cover that is used for entangling circuit breaker side middle part handle, handle cover top is equipped with the last cover shell that is used for shielding circuit breaker upper portion, handle cover below is equipped with the lower cover shell that is used for shielding circuit breaker lower part, it is equipped with first sliding tray to go up the cover shell below, the cover shell top is equipped with the second sliding tray down, handle cover top fixedly connected with extend to in the first sliding tray and with first sliding tray sliding fit's first sliding plate, handle cover below be equipped with extend to in the second sliding tray and with second sliding tray sliding fit's second sliding plate, it makes by insulating rubber materials to go up cover shell, lower cover shell, handle cover, first sliding plate and second sliding plate.

Furthermore, two sides of the top of the first sliding plate are fixedly connected with first limiting sliding blocks, the inner side wall of the first sliding groove is provided with a first limiting sliding groove matched with the first limiting sliding blocks, two sides of the lower part of the second sliding plate are fixedly connected with second limiting sliding blocks, and the inner side wall of the second sliding groove is provided with a second limiting sliding groove matched with the second limiting sliding blocks.

Furthermore, the outer surface of the handle sleeve is provided with a wavy anti-slip groove.
