Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a built-in heat dissipation fin strip of a distribution box. Background Art

[0002] The distribution box is divided into power distribution box, lighting distribution box and metering box. It is the final equipment of the distribution system. The distribution box is a general term for the motor control center. The distribution box is used in occasions where the load is relatively dispersed and there are fewer circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The distribution box has a reasonable distribution of power, convenient opening and closing of the circuit, a high level of safety protection, and can intuitively display the conduction status of the circuit.

[0003] During the use of the existing distribution box with built-in cooling fins, the cooling fin plates are manually installed by bolts or welding, which will cause troubles in maintenance, replacement and disassembly. At the same time, it is relatively cumbersome to replace a single fin, which is not conducive to maintenance operations of staff. Utility Model Content

[0008] Preferably, the fixing block is provided with a second slot at a position close to the pressing block, the second slot cooperates with the pressing block, and the fixing block cooperates with the rectangular slot.

[0009] Through the above technical solution, the second card slot is opened at the upper end of the fixed block, and the second card slot is close to the position of the pressing block. At the same time, the second card slot and the card block cooperate with each other, and the fixed block and the rectangular groove cooperate with each other. The heat dissipating fin plate can be fixed by embedding the fixed block on the back of the heat dissipating fin plate into the inside of the rectangular groove.

[0010] Preferably, one end of the spring is connected to the inner wall of the spring groove, and the other end of the spring is fixedly connected to the pressing block.

Due to the action of the spring, the pressure block can be pushed to embed into the second slot, thereby fixing the fixed block.

[0012] Preferably, the card block is snap-fitted with the first card slot.

[0014] Preferably, the heat dissipation fins are plugged into slots.

[0015] Through the above technical solution, slots are equidistantly arranged on the inner wall of the card board, and heat sink fins are inserted into the slots. Thus, the heat sink fins can be pulled out, thereby facilitating replacement and avoiding overall dismantling.

[0016] Preferably, a screw thread is provided at the lower end of the positioning rod, and the lower end of the positioning rod is threadedly connected to the bottom of the positioning hole through the screw thread.

[0017] Through the above technical solution, the positioning hole passes through the slot, and a screw thread is arranged inside the bottom positioning hole, that is, when the positioning rod is rotated, the lower end of the positioning rod is disengaged from the threaded connection with the lower end of the positioning hole, and then the positioning rod is pulled out, and the heat sink fin is pulled out from the slot, so that the heat sink fin can be replaced. After the replacement, the positioning rod is inserted into the positioning hole again, and the positioning rod is rotated to fix the positioning rod to the lower end. In this way, a single heat sink fin can be replaced by simply rotating the positioning rod, which facilitates the replacement operation of the staff.

[0018] Compared with the prior art, the utility model provides a built-in heat dissipation fin of a distribution box, which has the following beneficial effects:

At the same time, the lower end of the fixed block drives the card block, so that the card block is separated from the card connection relationship with the first card slot, that is, by obliquely pulling out the heat dissipation fin plate, the heat dissipation fin plate drives the fixed block to escape from the inside of the rectangular slot, thereby facilitating the disassembly of the entire heat dissipation fin plate.

[0020] 2. The utility model provides components such as a clamping plate and a positioning rod. When the positioning rod is rotated, the lower end of the positioning rod is disengaged from the threaded connection with the lower end of the positioning hole. Then, the positioning rod is pulled out and the heat sink fin is pulled out from the slot. The heat sink fin can be replaced. After the replacement, the positioning rod is inserted into the positioning hole again and the positioning rod is rotated to fix the positioning rod to the lower end. In this way, a single heat sink fin can be replaced by simply rotating the positioning rod, which is convenient for the staff to replace the fin. BRIEF DESCRIPTION OF THE DRAWINGS
