If there are foreign objects in the pipe, it is very difficult for the wire threading device to break through the foreign objects and continue to work, which not only increases the construction time, but also may cause wire entanglement or jamming due to improper operation, further affecting the project progress. Therefore, it needs to be improved and optimized. Content of the Utility Model

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. When the present utility model pulls the lead wire forward, when there is a foreign object blocking the advancement of the lead wire head in the pipeline, the relative force between the blocking object and the lead wire causes the clamping block to push the moving block to slide inside the guiding groove. Due to the shape of the moving block, when it moves to the lowest end of the guiding tube, it slides into the fixing groove and is clamped with it. And the moving block and the compression block compress the compression spring relatively. Through continuous relative force, the lead wire squeezes the push block again, the push block pushes the clamping block to squeeze the moving block again. Under the action of the squeezing force of the clamping block and the elastic force of the spring, the moving block slides from the chute to the inside of the guiding groove due to the shape guidance, enabling the rotating column to rotate while sliding inside the lead wire head. This design makes it possible that when the lead wire head encounters a blocking object during advancement, under the combined action of the rotation and forward and backward movement of the rotating column, a drilling force is formed, causing the blocking object to be broken through. Compared with traditional devices, when encountering a foreign object blockage, it not only realizes the physical extrusion of the blocking object, but also through the rotational movement of the rotating column, it is transformed into a combined drilling force. This drilling force effectively combines the axial thrust and the rotational cutting force, and can penetrate or break the blocking object more efficiently, significantly reducing the operation interruption and delay caused by obstacles, as well as the energy storage and release of the compression spring, realizing the accumulation and redistribution of force, thereby intelligently adjusting the advancement strategy to ensure that the lead wire head can continuously and stably advance forward.
[0013] 2. When the present utility model rotates the knob, the knob drives the transmission column to rotate, the transmission column drives the threaded rod to rotate, causing the slider to slide on the outer surface of the threaded rod. Through the connection of the connecting rod and the connecting block, the four sliders move up and down synchronously, and the slider drives the universal wheel to move up and down. This design not only ensures the stability of the device during movement, but also enables the device to be evenly stressed when fixed, enhancing the overall stability, thereby realizing the movement and fixation of the device, greatly improving the flexibility of the device. Compared with traditional devices, this mechanical transmission method ensures the stability and accuracy of the device during movement or fixation, avoiding shaking or deviation caused by improper control during working hours.

Specific implementation manner
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0021] As Figures 1 to 5 shown, the present invention provides a wire threading device for building electrical construction, including a lead wire 7 and a lead wire head 9. The left end of the lead wire 7 is fixedly installed with a pushing block 14, and a clamping block 15 is fixedly installed on the outer surface of the pushing block 14. A moving block 12 is slidably installed inside the pushing block 14 and the moving block 12 is clamped with the pushing block 14. The lead wire head 9 is slidably installed outside the lead wire 7. A guiding tube 11 is fixedly installed inside the lead wire head 9, and a guiding groove 13 is opened on the outer surface of the guiding tube 11. The clamping block 15 is slidably installed inside the guiding groove 13.
[0022] The staff puts the lead wire head 9 into the pipeline, pulls the lead wire 7 to the left. The lead wire 7 drives the large fixing ring 6 and the small fixing ring 5 to rotate. The lead wire head 9 drives the lead wire 7 and the rotating column 28 to advance inside the pipeline. When encountering an obstacle during the advancement, the obstacle squeezes the rotating column 28, and there is relative extrusion between the obstacle and the lead wire 7. The relative force squeezes the pushing block 14. The pushing block 14 drives the clamping block 15 to squeeze the moving block 12. The clamping block 15 and the moving block 12 run inside the guiding groove 13, and the moving block 12 is squeezed into the fixing groove 16 according to the guiding shape of the moving block 12 to complete the rotation of the moving block 12. The moving block 12 drives the rotating column 28 to rotate inside the lead wire head 9. The moving block 12 and the compression block 19 relatively squeeze the spring 20. Due to the continuous application of thrust by the lead wire 7, there is always a relative force between the lead wire 7 and the obstacle. The clamping block 15 squeezes the moving block 12 again. Under the elastic force of the spring, the moving block 12 and the sliding groove 17 slide into the guiding groove 13 again according to the guiding action of the shape, completing the second sliding and rotation, so as to break through the obstacle.
[0023] By pulling the lead wire 7 forward, when there is a foreign object blocking the advancement of the lead head 9 inside the pipeline, the relative force between the blocking object and the lead wire 7 causes the clamping block 15 to push the moving block 12 to slide inside the guiding groove 13. Due to the shape of the moving block 12, when it moves to the lowest end of the guiding tube 11, it slides into the fixing groove 16 and is clamped with it. And the moving block 12 and the compression block 19 compress the spring 20 relatively. Through continuous relative force, the lead wire 7 squeezes the push block 14 again. The push block 14 pushes the clamping block 15 to squeeze the moving block 12 again. Under the action of the squeezing force of the clamping block 15 and the elastic force of the spring, the moving block 12 slides from the chute 17 into the guiding groove 13 due to shape guidance, causing the rotating column 28 to rotate while sliding inside the lead head 9. This design enables, when the lead head 9 encounters a blocking object during advancement, under the combined action of the rotation and forward and backward movement of the rotating column 28, a drilling force is formed, causing the blocking object to be broken through. Compared with traditional devices, when encountering a foreign object blockage, not only is physical extrusion of the blocking object achieved, but also through the rotational movement of the rotating column 28, it is transformed into a combined drilling force. This drilling force effectively combines axial thrust and rotary cutting force, can penetrate or break the blocking object more efficiently, significantly reduces operation interruptions and delays caused by obstacles, and through the energy storage and release of the compression spring 20, realizes the accumulation and redistribution of force, thereby intelligently adjusting the advancement strategy to ensure that the lead head 9 can continuously and stably advance forward.
[0024] Among them, a large fixing ring 6 is fixedly installed on the outside of the lead wire 7, a small fixing ring 5 is fixedly installed inside the lead wire 7, a rotating block 4 is fixedly installed inside the small fixing ring 5, a fixing shaft 3 is rotatably installed inside the rotating block 4, a frame 1 is fixedly installed on the outside of the fixing shaft 3, a threaded rod 22 is rotatably installed inside the bottom of the frame 1, three sliding columns 21 are fixedly installed inside the bottom of the frame 1, a slider 23 is threadedly sleeved on the outer surface of the threaded rod 22, and the slider 23 is slidably installed on the outer surface of the sliding column 21. Connecting rods 25 are fixedly installed between the left and right opposite surfaces of the two sliders 23, and connecting blocks 26 are fixedly installed between the front and back opposite surfaces of the two sliders 23.
[0025] The staff rotates the knob 29, the knob 29 drives the transmission column 30 to rotate, the transmission column 30 drives the threaded rod 22 to rotate. The rotation of the threaded rod 22 causes the slider 23 to slide on the outer surface of the threaded rod 22. The two sliders 23 are connected by the connecting rod 25, causing the left and right two sliders 23 to move up and down. The front and back two sliders 23 are connected by the connecting block 26, causing the four sliders 23 to move up and down synchronously. The slider 23 drives the universal wheel 24 to move up and down.
[0026] By rotating the knob 29, the knob 29 drives the transmission column 30 to rotate. The transmission column 30 drives the threaded rod 22 to rotate, causing the slider 23 to slide on the outer surface of the threaded rod 22. Through the connection of the connecting rod 25 and the connecting block 26, the four sliders 23 move up and down synchronously. The slider 23 drives the universal wheel 24 to move up and down. This design not only ensures the stability of the device during movement but also enables the device to be evenly stressed when fixed, enhancing the overall stability, thereby realizing the movement and fixation of the device, greatly improving the flexibility of the device. Compared with traditional devices, this mechanical transmission method ensures the stability and accuracy of the device during movement or fixation, avoiding shaking or deviation caused by improper control during work.

A rotating column 28 is fixedly installed at the bottom of the moving block 12. The rotating column 28 is fixedly installed inside the spring 20. A compression block 19 is fixedly installed at the left end of the spring 20. The compression block 19 is fixedly installed inside the lead head 9.

[0028] By opening the compression groove 27, the spring 20 can be compressed inside the compression groove 27 under the mutual action of the moving block 12 and the compression block 19. By providing the rotating column 28, the rotating column 28, driven by the moving block 12, completes rotation and sliding, causing the left end of the rotating column 28 to form a drilling force on the obstacle. The design of the compression groove 27 allows the spring 20 to effectively store and release energy when subjected to the mutual action of the moving block 12 and the compression block 19. The accumulation and release of this energy, combined with the rotation and sliding of the rotating column 28, enable the left end of the rotating column 28 to exert a more powerful and concentrated drilling force when encountering an obstacle. This drilling force not only enhances the penetration ability but also improves the penetration efficiency, enabling the lead head 9 to advance stably inside the pipeline and greatly improving the work efficiency.

The guiding action of the sliding groove 17 provides precise path control for the movement of the moving block 12. By carefully designing the shape and position of the sliding groove, it can be ensured that the moving block 12 can smoothly disengage from the fixing groove 16 when needed and slide along the predetermined path into the guiding groove 13, making the movement of the rotating column 28 smoother.
[0031] Among them, a transmission column 30 is fixedly installed at the top of the threaded rod 22. The transmission column 30 penetrates upward through the machine frame 1, and a knob 29 is fixedly installed at the top of the transmission column 30.
[0032] By providing the transmission column 30, when the knob 29 is rotated, the knob 29 drives the spring 20 to rotate, and the transmission column 30 drives the threaded rod 22 to rotate, so that the slider 23 slides up and down on the surface of the threaded rod 22, thereby enabling the universal wheel 24 to complete lifting. When it is necessary to move, the knob 29 is rotated to make the universal wheel 24 move on the ground. When the device is working, the knob 29 is rotated to make the universal wheel 24 not contact the bottom surface, so that the device is stably fixed on the ground and operates stably, greatly improving the flexibility of the device.

[0035] Among them, coil fixing strips 8 are fixedly installed on the front and back surfaces of the large fixing ring 6 and the small fixing ring 5. The two ends of the coil fixing strip 8 are respectively fixedly connected to the large fixing ring 6 and the small fixing ring 5. A guide coil 10 is fixedly sleeved on the outer surface of the fixing shaft 3.
[0036] By providing the coil fixing strip 8, the lead wire 7 will not fall off when it is wound between the large fixing ring 6 and the small fixing ring 5. By providing the guide coil 10, the lead wire head 9 drives the lead wire 7 to pass through the guide coil 10 to start operating. The guide coil 10 enables the lead wire 7 to have a fixed direction during operation, avoiding the winding and knotting of the lead wire 7, and making the device work more efficiently.
