Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a wire threading device for construction lines. Background Technology

[0002] In the process of building electrical construction, in order to reduce the probability of short circuits caused by accidents such as moisture and overheating, the wires need to be run through pre-embedded pipes during the wiring process. During the wire running process, the wire pulling device can assist in the running of the wires and improve the efficiency of building electrical construction.

[0003] In the existing technology, when wires are threaded through a wire threading device, it is usually necessary to thread the lead wire first and then thread the wire through it. This makes the wire threading device more complex in structure and more cumbersome to operate. It is time-consuming and laborious when threading long lines, and it is not convenient to use.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a wire threading device for construction lines to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A cable threading device for a construction line includes a cable threading conduit, a cable fixing mechanism, and a traction mechanism. The cable fixing mechanism is disposed inside the cable threading conduit and includes a magnetic ball, a connecting frame, a positioning frame, a positioning screw, and a guide wheel. The traction mechanism is disposed above the cable threading conduit and includes a sliding frame, a pulley, a push rod, a support plate, a threaded rod, a lifting frame, a buffer assembly, and a magnetic block. One end of the connecting frame is connected to the magnetic ball, and the other end of the connecting frame is connected to the positioning frame. The positioning screws are symmetrically arranged on the left and right sides of the positioning frame, and the guide wheels are symmetrically arranged on the upper and lower sides of the positioning frame. The pulley is installed at the bottom of the sliding frame, the push rod is fixedly connected to one side of the top of the sliding frame, the support plate is fixed to the sliding frame, the threaded rod is threadedly connected to the support plate, one end of the threaded rod is connected to the lifting frame through a movable locking block, and the magnetic block is connected to the lifting frame through a buffer assembly.

[0008] Preferably, the positioning frame is provided with a wire hole, and one end of the positioning screw is disposed in the wire hole.

[0009] Preferably, the guide wheel is rotatably connected to the positioning frame, and one end of the guide wheel is slidably connected to the inner wall of the conduit.

[0010] Preferably, the lifting frame is fixedly connected to sliders at both ends, and the inner side of the sliding frame is provided with corresponding sliding grooves, and the lifting frame is slidably connected to the sliding grooves through the sliders.

[0011] Preferably, the buffer assembly includes a buffer rod, a return spring, and a limiting block. One end of the buffer rod is connected to a magnetic block, and the other end of the buffer rod passes through a support plate and is connected to the limiting block. The return spring is sleeved on the outside of the buffer rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] By providing a cable fixing mechanism, the cable is fixed to the cable fixing mechanism during the threading process. By sliding the sliding frame, the magnetic block pulls the magnetic ball, causing the magnetic ball to roll inside the threading tube, which in turn moves the cable from inside the threading tube, making the threading operation easier.

[0014] By incorporating a threaded rod and a lifting frame, the threaded rod drives the lifting frame to move, adjusting the height of the magnetic block so that it can fit against the outside of the threading tube, allowing the magnetic block and magnetic ball to attract each other and improving threading efficiency.
