Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, in particular to a box-type distribution cabinet that is convenient for assembly and disassembly. Background Art

[0002] A distribution cabinet is a structured device used for power distribution and control of electrical equipment. It usually consists of multiple components, including circuit breakers, contactors, relays, transformers, etc. They are widely used in industrial and civil building fields and are key devices to ensure electrical safety and reliable power supply in buildings. At present, there are various types of distribution cabinets on the market, but there are still some problems. For example, traditional distribution cabinets have problems such as difficult maintenance, large floor area, and difficulty in transportation and installation. Therefore, people have been looking for better solutions to improve the design of distribution cabinets.

[0003] After retrieval, the Chinese utility model patent with the authorization announcement number of CN 221408175 U discloses a box-type distribution cabinet that is convenient for assembly and disassembly, including columns. There is a telescopic component directly arranged between two groups of columns. Three groups of box plates are inserted into the inner cavities of four groups of columns respectively. Four groups of partitions are inserted into the inner cavities of the four groups of columns at the ends far away from the box plates. A limiting component is arranged on the tops of the four groups of partitions. A water-blocking component is inserted into the inner cavities of the four groups of columns; the water-blocking component includes multiple groups of flap plates. The axles of the multiple groups of flap plates are fixedly connected with rotating shafts respectively. The ends of the rotating shafts far away from the flap plates are fixedly connected with gears. The telescopic component includes a first fixing block. One end of the first fixing block is slidably clamped at one end of a group of columns; by setting the box plates, since the box-type distribution cabinet is assembled by sliding and inserting the box plates into the columns, when a group of box plates is damaged, it can be replaced separately, thereby improving the practicability of the device and avoiding waste caused by the other parts of the distribution box being intact.

[0004] The above device has at least the following technical defects:

[0005] 1. The device sets a limiting component on the partition for fixing wires. The partition makes it difficult for the heat generated by the operation of electrical components inside the distribution cabinet to be discharged, thus affecting the service life of electrical components. In a more serious case, safety accidents may even occur.

[0006] 2. The device does not preset an installation rack for electrical components, which results in that electrical components can only be installed on box plates or partitions. The longitudinal dense arrangement of partitions will cause great trouble for workers to install electrical components. Therefore, the device has the problem of inconvenient installation.

[0007] 3. The device seals the power distribution cabinet by setting a waterproof component. The waterproof component adjusts the baffle through a motor, which not only increases the manufacturing cost of the device but also further increases the potential safety hazards of the device. When installing the power distribution cabinet, the staff generally reserve heat dissipation holes to discharge the heat inside the cabinet. Once the motor of the above device is damaged and the baffle cannot be opened, the heat inside the cabinet will accumulate, leading to safety accidents. Therefore, the safety factor of the above device is not high.

[0008] In summary, there are still various technical defects in the existing box-type power distribution cabinet that is convenient for assembly and disassembly, so it needs to be improved. Utility Model Content
