Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and particularly to a detachable and combinable distribution cabinet. Background Art

[0002] Distribution cabinets play a crucial role in the power system. Its main function is to connect electric energy from the incoming line, and then distribute the electric energy to each electrical equipment through internal circuit branches, electrical component switches and other devices, ensuring that the electric energy can be safely and stably delivered to each equipment that needs electricity. By controlling switches, circuit breakers and other devices, operations such as turning on, turning off and adjusting electrical equipment can be realized, so as to meet different electricity consumption needs; a variety of electrical components for protection are arranged inside the distribution cabinet, which can protect the internal and transmitted circuits, electrical equipment, etc. When a circuit fault occurs, further damage to equipment and circuits can be avoided.

[0003] The guide rails for installing electrical components inside the distribution cabinet are usually locked to the side walls of the distribution cabinet with screws after distance measurement. During the installation process, if it is found that the guide rails are installed offset or not straight, since the guide rails are fixed by screws, it is very difficult to adjust the guide rails, and the installation process is very complicated. It is necessary to drill holes and tap threads in the distribution cabinet before screwing, and its flexibility and convenience are often very poor, which is very inconvenient for later maintenance and replacement; moreover, the tightness of the screws may also affect the stability of the guide rails, causing poor contact of the electrical components on the guide rails, overheating of the contact points, and in severe cases, short circuits or electrical fires, affecting personal and property safety. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background art, and provide a detachable and combinable distribution cabinet. The lifting guide rails arranged inside the distribution cabinet can be disassembled and assembled more conveniently, and at the same time, welding or thread connection drilling can be reduced, and better fastening force can be provided, so that the distribution cabinet has better use reliability while being convenient for disassembly and assembly.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A detachable and combinable distribution cabinet, including a cabinet body, an inner door bracket and a plurality of lifting guide rails.
