Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a withdrawable low-voltage switch cabinet. Background Art

[0002] In factories and manufacturing industries, withdrawable low-voltage switchgear is used to control and distribute electricity. It can be used for the power supply of various equipment and machinery, such as motors, conveyor belts, lighting, etc. In commercial buildings, withdrawable low-voltage switchgear is used in the main power distribution system of the building, including large commercial centers, office buildings, shopping centers, etc., to ensure the stability and safety of power supply.

[0003] After searching: Chinese patent announcement number: CN220652777U, it relates to the technical field of switch cabinets, and discloses a withdrawable low-voltage switch cabinet, which relates to the technical field of switch cabinets. The switch cabinet includes a cabinet body, and a fixing component for fixing the cabinet body is arranged at the bottom end of the cabinet body. A drawer is slidably connected to the cabinet body through a sliding component. The drawer is equipped with a positioning component in conjunction with the cabinet body, and a dustproof and heat dissipation component is arranged on the top of the cabinet body. In the utility model, through the mutual cooperation between the mounting groove, the positioning plate, the positioning block, the spring, the rotating shaft and the positioning hole, when the positioning block passes through the positioning hole during the process of pulling out the drawer, the spring pushes the positioning plate to rotate so that the positioning block is stuck in the positioning hole, thereby avoiding too much drawer being pulled out at one time. At the same time, the positioning plate extends to the outside of the mounting groove, which is convenient for operation when releasing the positioning.

[0004] The above patent embodiment records that "in the process of pulling out the drawer, when the positioning block passes through the positioning hole, the spring pushes the positioning plate to rotate so that the positioning block is engaged with the positioning hole, thereby preventing the drawer from being pulled out too much at one time. At the same time, the positioning plate extends to the outside of the mounting groove, which is convenient for operation when releasing the positioning." The above embodiment records that by pulling out the drawer, the positioning block passes through the positioning hole, and then the spring will push the positioning plate to rotate so that the positioning block is engaged with the positioning hole, thereby preventing the drawer from being pulled out too much at one time. However, the problem of weak heat dissipation function inside the device is not taken into account, which will lead to excessive stability inside the device, and then cause the electronic components stored in the device to be damaged due to excessive temperature. Therefore, in response to the above-mentioned deficiencies, a new type of pull-out low-voltage switch cabinet is proposed. Utility Model Content
