Description

Technical Field

[0002] Threading devices used in building electrical construction are tools and equipment used to thread cables or wires through walls, floors, or other structures. Threading involves guiding a cable or wire through a steel wire, typically by tying one end of the wire to one end and then pulling the wire from the other end to pull it into the conduit. Using a threading device can improve threading efficiency by preventing cables or wires from being too rigid or too flexible to fit through curved pre-buried circuit conduits.

[0003] However, most of the wire threading devices used in building electrical construction now have the following problems:

[0004] For example, a wire threading device for building electrical construction with publication number CN217823977U, although the dust and impurities on the steel wire can be cleaned by rotating the cleaning brush, the cleaned dust easily sticks to the cleaning brush, and the steel wire has a certain length. The dust sticking to the cleaning brush easily affects the cleaning effect of the steel wire, and it is inconvenient to conveniently collect and process the cleaned dust; at the same time, for example, a wire threading device for building electrical construction with publication number CN220283150U, although the rotating winding of the winding roller can wind the steel wire, the winding roller is rotatably fixed to the equipment, and the length of the steel wire wound by winding rollers of different sizes is limited. In different construction scenarios, different lengths of steel wire are required, and it is inconvenient to disassemble and replace the winding roller on the equipment.

[0005] Therefore, we have made improvements to this and proposed a wire threading device for building electrical construction. Utility Model Content

[0034] Example 2:

[0035] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0036] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the cross-section of the slider 2 and the pull rod 5 is "T"-shaped, the side end face of the limit plate 4 fits with the inner side face of the slider 2, and the pull rod 5 is fixedly connected to the center part of one side of the limit plate 4. The length of the pull rod 5 is greater than the length of the block 7, which can ensure that when the pull rod 5 is pulled, the pull rod 5 can smoothly drive the block 7 to detach from the protective shell 1 and the slider 2, thereby improving the disassembly effect.

[0037] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the blocks 7 are symmetrically distributed on the left and right sides of the pull rod 5, the length of the connecting frame 8 is greater than the length of the winding roller 10, and the output shaft of the first servo motor 9 is fixedly connected to the center of one end of the winding roller 10, which can ensure that the first servo motor 9 can drive the winding roller 10 to rotate smoothly, and rotating the winding roller 10 can reel in the wound steel wire.

[0038] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the second springs 12 are symmetrically distributed on the upper and lower sides of the mounting frame 11, the second springs 12 correspond to the guide wheels 13 one by one, and the output shaft of the second servo motor 14 is fixedly connected to the center of the gear 15, which can ensure that when the second springs 12 on both sides push the guide wheels 13, the guide wheels 13 can clamp and guide the passing steel wire.

The fan 21 can absorb and collect the cleaned dust through the multiple suction pipes 22 on the air box 18. While collecting dust, under the isolation of the isolation net 20, dust impurities are prevented from damaging the fan 21, thereby improving the dust cleaning effect on the surface of the steel wire.
