[0028] Embodiment:

[0029] Such as Figures 1-6As shown in the figure, an embodiment of the present invention provides a wire threading device for building electrical construction, which includes a wire threading disc 1. A rotating sleeve 101 is rotatably connected to the lower inner wall of the wire threading disc 1. A fixed column 105 is fixedly connected to the middle of the lower inner wall of the wire threading disc 1. A wire threading rope 102 is installed on the outer side wall of the rotating sleeve 101. A grip 4 is fixedly connected to the upper side wall of the wire threading disc 1. A wire threading groove 405 is arranged inside the grip 4. A plurality of driven wheels 402 are rotatably connected inside the wire threading groove 405. A transmission belt 403 is connected to the outer side wall of the driven wheel 402. The transmission belt 403 is matched with a transmission roller 303. The transmission motor 301 can drive a plurality of transmission rollers 303 to rotate through a transmission box 302. The cooperation between the transmission rod 303 and the transmission belt 403 can pull out or pull in the wire threading rope.

[0030] A transmission box 3 is fixedly connected to the lower side wall of the grip 4. A transmission motor 301 and a transmission box 302 are installed inside the transmission box 3. A plurality of transmission rollers 303 are fixedly connected to the output end of the transmission box 302. A power storage box 2 is installed on the left side wall of the wire threading disc 1. A power storage component and a control main board are arranged inside the power storage box 2. A cooperation trigger 404 is installed on the inner side wall of the grip 4. Both the cooperation trigger 404 and the transmission motor 301 are electrically connected to the control main board. The cooperation trigger 404 can control the switch and rotation direction of the transmission motor 301 through the control main board.

[0031] A cooperation ratchet 106 is fixedly connected to the upper side wall of the rotating sleeve 101. A rotating rod 602 is rotatably connected inside the front side wall of the wire threading disc 1. A limiting frame 6 is fixedly connected to the front end of the rotating rod 602. The head of the limiting frame 6 is made of stainless steel material. An adsorption frame 5 is fixedly connected to the front side wall of the wire threading disc 1. An electromagnet block is arranged inside the adsorption frame 5. The electromagnet block is matched with the head of the limiting frame 6. After the electromagnet block is powered on, it can fix the head of the limiting frame 6, so that the rotating rod rotates. A limiting piece 601 is fixedly connected to the bottom of the limiting frame 6. The limiting piece 601 is matched with the cooperation ratchet 106. The limiting piece 601 can limit the counterclockwise rotation of the cooperation ratchet 106. When the rotating rod 602 rotates, it can drive the limiting piece 601 to rotate, so that the limiting piece 601 no longer restricts the rotation of the cooperation ratchet 106. A coil spring 104 is fixedly connected between the rotating sleeve 101 and the fixed column 105, which is convenient for the rotating sleeve 101 to rotate back. A torsion spring is arranged between the rotating rod 602 and the wire threading disc 1, which is convenient for the rotating rod to reset.

[0032] The upper side wall of the threading disk 1 is provided with a rope outlet hole 103, and the right side wall of the handle 4 is fixedly connected with a rope outlet block 401. The threading rope 102 passes through the rope outlet hole 103, the rope threading groove 405 and the rope outlet block 401 in sequence. The threading rope 102 is woven from two steel cables, so that the threading rope 102 can be bent and will not be folded back. The outer side wall of the threading rope 102 is fixedly connected with a nylon sleeve to protect the steel cable. The outer end of the threading rope 102 is fixedly connected with a fixed head 1021 A connecting ring 1022 is fixedly connected to the inside of the fixed head 1021, and a connecting rope 1024 is fixedly connected to the end of the connecting ring 1022 away from the fixed head 1021. A connecting sleeve 1025 is fixed to the outer end of the connecting rope 1024, and a conical sleeve 1023 is fixedly connected to the outer wall of the connecting rope 1024. The conical sleeve 1023 is made of silicone material. The threading rope 102 can fix the wires and the threading rope 102 through the connecting sleeve 1025 and the conical sleeve 1023.

[0033] Working principle: First, the wire and the threading rope 102 are fixed through the connecting wire sleeve 1025 and the conical sleeve 1023. The conical sleeve 1023 is made of silicone material, which can ensure the stable connection between the wire and the threading rope. The operator controls the switch and direction of the transmission motor 301 through the matching trigger 404 on the grip 4. The matching trigger 404 and the transmission motor 301 are both electrically connected to the control main board. After receiving the signal of the matching trigger, the control main board controls the start and direction of the transmission motor; the transmission motor 301 drives a plurality of transmission rollers 303 to rotate through the transmission box 302, and the transmission rollers 303 cooperate with the transmission belt 403 to drive the threading rope 102 to move in the threading groove 405. The threading rope 102 passes through the rope outlet hole 103, the rope threading groove 405 and the rope outlet block 401 in sequence, thereby realizing the pulling of the wire; the pulling of the threading rope 102 causes the rotating sleeve 101 to rotate around the fixed column 105, and a coil spring 104 is fixedly connected between the rotating sleeve 101 and the fixed column 105. When the threading rope is pulled, the coil spring 104 is stretched to provide elastic force for the rotation of the rotating sleeve; in the threading process, the head of the limit frame 6 is made of stainless steel material and cooperates with the electromagnet block inside the adsorption frame 5. After the electromagnet block is energized, it can fix the head of the limit frame 6, thereby causing the rotating rod 602 to rotate. When the limit frame needs to be released, the electromagnet block is powered off. The head of the limit frame 6 is no longer fixed, and the rotating rod 602 is reset by the action of the torsion spring; the bottom of the limit frame 6 is fixedly connected with the limit plate 601, and the limit plate 601 cooperates with the matching ratchet 106. The limit plate 601 can limit the matching ratchet 106 to rotate counterclockwise. When the rotating rod 602 rotates, it drives the limit plate 601 to rotate, so that the limit plate no longer restricts the matching ratchet 106, allowing the matching ratchet to rotate clockwise to realize the rotation of the threading rope. When the threading rope 102 needs to be rotated, the driving roller 303 is rotated in the opposite direction by controlling the steering direction of the transmission motor 301, thereby driving the threading rope to move in the opposite direction in the threading groove 405. At this time, the rotating sleeve 101 rotates under the elastic force of the coil spring 104 to realize the rotation of the threading rope, which is convenient for pulling the wire back or adjusting the position. Through the above steps, the wire threader for building electrical construction can realize the stable pulling and flexible adjustment of the wire, and improve the threading efficiency and construction quality.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
