A plurality of clamping blocks 113 are fixedly arranged on the inner wall of the weak current box body 16. A limiting groove 114 is provided in the top of the weak current box body 16. A double-threaded rod 115 is rotatably arranged in the limiting groove 114. A pair of sliders 116 are slidably arranged in the limiting groove 114. The sliders 116 are threadedly connected with the double-threaded rod 115. A connecting rod 117 is hingedly arranged on the sliders 116. A square limiting block 118 is slidably arranged in the limiting groove 114. The other end of the connecting rod 117 is hingedly arranged with the bottom of the square limiting block 118. A worm gear 119 is fixedly arranged on the double-threaded rod 115. A worm 120 is rotatably arranged in the limiting groove 114. A knob 121 is fixedly arranged at the bottom of the worm 120.

[0026] The expansion bolts 12 all penetrate the embedded frame 11, and multiple wire threading tubes 13 are distributed in a linear row. Multiple wire grooves 15 are located above the multiple wire threading tubes 13 and correspond to the number of their positions. Multiple wire threading holes 112 are located directly above the multiple wire grooves 15 and correspond to the number of their positions. Multiple wire clamping blocks 113 are respectively located directly above the wire threading holes 112. A square limit block 118 penetrates the limit groove 114, and a worm 120 penetrates the limit groove 114. The worm wheel 119 is located at the center of the double-headed threaded rod 115.

[0030] In the specific implementation process, Figure 1 and Figure 2As shown, when heat is generated in the weak current box body 16, the cooling fan 22 generates wind to cool the interior, and discharges the internal heat through the heat dissipation slot 2, forming a circulating air duct to continuously circulate and cool the interior. The dustproof net 21 can prevent a large amount of dust from entering the interior, thereby affecting the use. Through the coordinated use of the heat dissipation slot 2, the dustproof net 21 and the cooling fan 22, the heat generated inside the box can be discharged through heat dissipation, reducing the overall safety hazard.

[0031] Specifically, the working principle and operation method of the utility model are as follows:

The knob 121 is turned, and the knob 121 drives the worm 120 to rotate. The worm 120 drives the double-headed threaded rod 115 to rotate through the worm gear 119. The double-headed threaded rod 115 drives the slider 116 to move to the middle, and the slider 116 is connected to the connecting rod 11. 7 Push the square limit block 118 upward to insert the square limit block 118 into the square hole 14, and limit the weak current box body 16 through the square limit block 118 and the square hole 14, squeeze the weak wires in the box through the groove on the clamping block 113 into the clamping block 113, align the weak wires to prevent them from being entangled, close the protective door 19 and lock the door lock 111, and complete the installation of the weak current box body 16. When disassembling, replacing or repairing, turn the knob 121 to align the disassembly, replacement or repair;

[0033] Step 2: When heat is generated in the weak current box body 16, the cooling fan 22 is started. The cooling fan 22 generates wind to cool the inside, and discharges the internal heat through the heat dissipation slot 2, forming a circulating air duct to continuously circulate and cool the inside. The dustproof net 21 can prevent a large amount of dust from entering the inside, thereby affecting the use;
