Description

Technical Field

[0001] The utility model relates to the technical field of building electrical construction, and particularly relates to a wire threading device for building electrical construction. Background Technique

[0002] Building engineering refers to the planning, surveying, design, construction, completion and other technical works for the new construction, renovation or expansion of buildings and ancillary structures, as well as the completed engineering entities and the installation works of their supporting lines, pipelines and equipment. In modern building engineering construction, electrical pipelines are generally embedded in walls and floors in a concealed manner. After the main structure construction is completed, wire threading operations for electrical pipelines begin. Since wires and cables are relatively soft and it is difficult to pass through the pipelines, a wire threading device is needed to assist in wire threading.

[0003] Currently, most of the existing wire threading devices are composed of a steel rope, a spring and a connector. The spring connects the steel rope and the connector, and a connecting ring for facilitating the passage of the line is installed on the connector. When in use, first pass the wire threading device through the pipeline, then pass the line through the connecting ring and connect it to the connecting ring. After that, wind the tape around the connection to fix the line and the connecting ring to ensure the fixation of the line on the connecting ring. Finally, pull the steel rope to drive the line to pass through the pipeline. After passing through the pipeline, in order to facilitate the removal of the line, the line is generally cut short directly, but there is still tape wound around the connector. When using it next time, the tape needs to be torn off to connect the line again, and the operation is relatively cumbersome. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wire threading device for building electrical construction to solve the problems raised in the above background technique.

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The present invention provides a wire threading device for building electrical construction as shown in Figures 1 to 5 and includes:

[0031] A storage box 1, the storage box 1 is disc-shaped, a reel 2 is rotatably installed inside the storage box 1, a rotary handle 3 is rotatably arranged on the front side of the storage box 1, and the inner end of the rotary handle 3 is fixedly connected to the middle part of the front side of the reel 2;

[0032] A pulling wire 4, one end of the pulling wire 4 is connected to the reel 2, the other end of the pulling wire 4 is rotatably connected to a first tightening assembly 5, one end of the spring wire 6 is connected to the first tightening assembly 5 away from the pulling wire 4, and one end of the spring wire 6 away from the first tightening assembly 5 is connected to a second tightening assembly 7.

[0034] After the wire end is inserted into the first tightening frame 9, then rotate the installation frame 8, the rotation of the installation frame 8 drives the first screw 11 to rotate, thereby pushing the first extrusion block 12 to move inside the first tightening frame 9, so that the first extrusion block 12 squeezes the wire end to fix the wire end by extrusion.

[0035] The second tightening assembly 7 includes a second tightening frame 13 and a U-shaped member 14. The second tightening frame 13 is connected to the spring wire 6. A second pulley 15 is rotatably installed inside the U-shaped member 14. A second screw 16 is fixed to the left side of the U-shaped member 14. The second screw 16 threadedly penetrates through the right side wall of the second tightening frame 13 and extends into the second tightening frame 13. A second extrusion head 17 is fixed to the rod head of the second screw 16 inside the second tightening frame 13.

[0036] The wire end passes through the second tightening frame 13 on the second tightening assembly 7, and then the U-shaped member 14 is rotated. The rotation of the U-shaped member 14 drives the second screw 16 to rotate. The rotation of the second screw 16 pushes the second extrusion head 17 to move inside the second tightening frame 13, so that the second extrusion head 17 squeezes the wire inside the second tightening frame 13 to squeeze and fix the wire inside the second tightening frame 13.

[0037] The mounting frame 8, the first tightening frame 9, the first pulley 10, and the first screw 11 are all made of alloy steel by machining, with high structural strength and not easily damaged.

[0039] Both the first extrusion block 12 and the second extrusion head 17 are made of rubber material by machining.

[0040] The pulling wire 4 is made by twisting three strands of plastic steel, with high tensile strength, not easily broken, durable and anti-aging, and strong resilience.

[0041] Support bases 18 are fixed to both the front and rear sides of the storage box 1, and a handle 19 is fixed to the top of the storage box 1.

[0042] A guiding box 20 is provided on the right side of the storage box 1. Inside the guiding box 20, there are a first guiding wheel 21, a second guiding wheel 22, a third guiding wheel 23, and a fourth guiding wheel 24. The first guiding wheel 21 and the second guiding wheel 22 are arranged horizontally in parallel. The third guiding wheel 23 and the fourth guiding wheel 24 are arranged horizontally in parallel. The third guiding wheel 23 is located directly below the first guiding wheel 21, and the fourth guiding wheel 24 is located directly below the second guiding wheel 22. The pulling wire 4 passes through the guiding box 20.

[0043] In the present utility model, during use, the second tightening assembly 7 and the first tightening assembly 5 are sequentially inserted into the wire tube. Then, the pulling wire 4 in the storage box 1 is pulled, and the pulling wire 4 is pushed into the wire tube, so that the pulling wire 4 penetrates through the wire tube. The second tightening assembly 7 and the first tightening assembly 5 extend out from the other end of the wire tube. Then, the wire end is passed through the second tightening frame 13 on the second tightening assembly 7, and then penetrates through the first tightening frame 9 on the first tightening assembly 5. Then, the mounting frame 8 and the U-shaped member 14 are respectively rotated. The rotation of the mounting frame 8 drives the rotation of the first screw 11, thereby pushing the first pressing block 12 to move within the first tightening frame 9, so that the first pressing block 12 presses the wire end to squeeze and fix the wire end. The rotation of the U-shaped member 14 drives the rotation of the second screw 16, and the rotation of the second screw 16 pushes the second pressing head 17 to move within the second tightening frame 13, so that the second pressing head 17 presses the wire within the second tightening frame 13 to squeeze and fix the wire within the second tightening frame 13. Thus, the first tightening assembly 5 and the second tightening assembly 7 are firmly connected to the wire, which is quick and convenient, and the connection and fixation are firm, and the detachment of the wire during the traction threading process can be avoided;

[0044] Then, the handle 19 is rotated. The rotation of the handle 19 drives the rotation of the winding and unwinding wheel 2. The rotation of the winding and unwinding wheel 2 winds the pulling wire 4, which is convenient for the storage of the pulling wire 4. At the same time, the winding of the pulling wire 4 drives the wire to pass through the wire tube. After the threading is completed, only by rotating the mounting frame 8 and the U-shaped member 14 in the reverse direction, the extrusion fixation of the wire is released, and then the wire can be easily removed, which is quick, convenient, time-saving and labor-saving, and greatly improves the work efficiency.
