Therefore, this utility model provides an electrical wire puller for building electrical construction. Utility Model Content

[0012] Beneficial effects
[0013] This utility model provides an electrical wiring harness for building electrical construction. Compared with the prior art, it has the following advantages:
[0014] 1. This electrical wiring device for building electrical construction works by inserting the cable through the coil and then operating the knob to drive the worm gear to rotate, which in turn drives the worm wheel, rotating shaft and threaded rod to rotate, causing the connecting plate to slide along the guide rod, which drives the conical ring to push the elastic clamp plate, so that the elastic clamp plate clamps the cable more tightly and prevents the cable from falling off during the wiring process.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides two technical solutions:
[0025] Figures 1-6The first embodiment is shown: an electrical wiring device for building electrical construction, including a wire harness 1, a guide component 2 at one end of the wire harness 1, and a plug-in component 3 at the other end of the wire harness 1; the plug-in component 3 includes a cylindrical housing 31 fixedly connected to the end of the wire harness 1, a plurality of coils 32 at one end of the cylindrical housing 31, the coils 32 extending into the interior of the cylindrical housing 31, a plurality of elastic clamps 321 fixedly connected to the coils 32 and placed inside the cylindrical housing 31, the plurality of elastic clamps 321 forming a conical structure, and a channel for cable insertion is formed between the coils 32 and the elastic clamps 321, and a conical ring 33 is sleeved on the outer side of the elastic clamps 321. A groove 311 is provided on the outer side of the cylindrical housing 31, and a fixing frame 34 is installed on the inner wall of the cylindrical housing 31 away from the elastic clamps 321, and a plurality of guide rods 35 are fixedly connected between the fixing frame 34 and the inner end of the cylindrical housing 31. A connecting plate 331 is fixedly connected between multiple conical rings 33, and the connecting plate 331 is slidably connected to the guide rod 35. Two shaft brackets 38 are fixedly connected to the side surface of the fixed frame 34 facing away from the elastic clamping plate 321. A worm gear 37 is rotatably provided between the two shaft brackets 38. A connecting shaft 371 is installed at one end of the worm gear 37. One end of the connecting shaft 371 passes through the inner wall of the cylindrical housing 31 and extends outward. A knob 372 is installed at the end of the connecting shaft 371 and is located in the groove 311. A worm wheel 362 is meshed on the worm gear 37. A rotating shaft 36 is installed at one end of the worm wheel 362. The rotating shaft 36 passes through the outer surface of the fixed frame 34 and extends to the other side. A threaded rod 361 is installed at one end of the rotating shaft 36. The threaded rod 361 is threaded through the connecting plate 331 and extends to the other side. One end of the threaded rod 361 is rotatably set on the inner end of the steel wire harness 1.
[0026] Specifically, by operating the knob 372, the worm 37 is driven to rotate. Since the worm 37 is meshed with the worm wheel 362, the rotation of the worm 37 will drive the worm wheel 362 to rotate, which in turn causes the rotating shaft 36 and the threaded rod 361 to rotate. The rotation of the threaded rod 361 will cause the connecting plate 331 to slide along the guide rod 35, which will drive the conical ring sleeve 33 to move. Since the conical ring sleeve 33 is fitted on the outside of the elastic clamping plate 321, it will push the conical ring sleeve 33 to move on the elastic clamping plate 321, further squeezing the elastic clamping plate 321, so that the elastic clamping plate 321 clamps the cable more tightly, ensuring that the cable is firmly connected to the plug assembly 3, preventing the cable from falling off during the threading process. Moreover, this operation does not require bending the cable, solving the problems of increased cable head size and cumbersome operation in existing threaders.
[0027] Furthermore, the groove 311 facilitates the accommodation of the knob 372, ensuring that the knob 372 does not protrude from the cylindrical housing 31, thus preventing interference between the knob 372 and the pipe during the threading process.
[0028] Figures 1-6The second embodiment is shown, and the main difference from the first embodiment is that the guide assembly 2 includes a guide head 21 fixedly connected to the other end of the wire harness 1, and a guide wheel 22 is rotatably provided on the guide head 21.
[0029] Specifically, during the threading process, the guide wheel 22 can reduce the resistance during threading, making it easier for the entire threader to move along channels such as pipes or wire troughs, thereby improving threading efficiency.
[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0031] Working principle: First, when using the cable to be threaded, connect it to the plug-in component 3. Insert the cable from the coil 32 until the cable passes through the elastic clamp 321. The elastic clamp 321 can initially fix and guide the cable.
[0032] Then, by operating the knob 372, the worm 37 is driven to rotate. Since the worm 37 is meshed with the worm wheel 362, the rotation of the worm 37 will drive the worm wheel 362 to rotate, which in turn causes the rotating shaft 36 and the threaded rod 361 to rotate. The rotation of the threaded rod 361 will cause the connecting plate 331 to slide along the guide rod 35, which will drive the conical ring sleeve 33 to move. Since the conical ring sleeve 33 is fitted on the outside of the elastic clamping plate 321, it will push the conical ring sleeve 33 to move on the elastic clamping plate 321, further squeezing the elastic clamping plate 321, so that the elastic clamping plate 321 clamps the cable more tightly, ensuring that the cable is firmly connected to the plug-in assembly 3. This allows the electrical cable puller to complete the cable pulling task more conveniently and efficiently, avoiding the cable from falling off during the cable pulling process. Moreover, this operation does not require bending the cable, solving the problems of increased cable head volume and cumbersome operation of existing cable pullers.
