After the excavation is completed, the steel pipe is placed in the laying trench, and then the PVC pipe is put into the steel pipe. Then, it is necessary to thread the cable into the PVC pipe and then conduct an inspection.
[0003] When threading the cable into the PVC pipe, a pipe threading device is required. In the prior art, a relatively smooth material is usually selected to make the pipe threading device. Sometimes, two or three strands of materials are wound together as the wire body of the pipe threading device. However, due to the gravitational force, the wire body in the PVC pipe has a downward acting force, and any pipe threading device made of any material may still be blocked when threading into the PVC pipe. Content of the Utility Model

A feeding groove that is communicated with the connecting section and has an inner diameter value equal to the inner diameter value of the through cavity is opened in the docking section.
[0007] A bundling ring with different feeding diameters is detachably installed in the body. The bundling ring is connected to the through cavity and the docking section.
[0008] In one implementation manner, the connecting section wraps its structure around the body through the inner groove. The docking section is connected to the body and the feeding groove is docked with the through cavity.

A clamping groove with a width less than half of the width of the bundling ring is opened in the through cavity. A clamping groove with a width less than half of the width of the bundling ring is also opened on the feeding groove. And a limiting groove is opened on the side wall of the through cavity. The opening depth of the limiting groove on the through cavity and the width of the clamping groove add up to half of the width of the bundling ring.
[0010] In one embodiment, a connecting sleeve is installed at the end of the pipe-passing traction wire extending towards the cable. The connecting sleeve is made of rubber and has a connecting groove formed inside it. The cable is connected to the pipe-passing traction wire by being placed in the connecting groove.
[0011] In one embodiment, a limiting groove is also formed on the side wall of the material-passing groove. The width of the limiting groove formed on the material-passing groove is smaller than the thickness of the beam material ring.

Specific implementation manners
[0024] The following will detail the implementation manners of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.
[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0026] Figures 1 - 5 This is an embodiment of the present utility model. The specific problem targeted by this specific embodiment is that when threading a cable 3 into a PVC pipe, a pipe threading device is required. In the prior art, materials that are relatively smooth are usually selected to make the pipe threading device. Sometimes, two or three strands of materials are wound together as the wire body of the pipe threading device. However, due to the gravitational force, the wire body in the PVC pipe will have a downward acting force. Any pipe threading device made of any material may still be blocked when threading into the PVC pipe. Based on the problem of the cable 3 not passing smoothly through the PVC pipe, this solution proposes a pipe threading device for urban lighting projects. First, the pipe threading traction line 1 is first connected to the cable 3, and the cable is driven to move followingly by the winding of an external winding device connected by the pipe threading traction line 1, and then passes through the PVC pipe to achieve the pipe threading effect. Moreover, when the pipe threading traction line 1 passes through the PVC pipe, the PVC pipe can be independent outside the pipe threading auxiliary device 2. Furthermore, it can be passed through from an angle that is easy to pass through, for example, directly passing through vertically using gravity. Then, after the pipe threading traction line 1 is inserted, the PVC pipe can be pushed into the pipe threading auxiliary device 2 to perform the subsequent steps of threading the cable 3.
[0027] This solution is specifically a pipe threading device for urban lighting projects. It is provided with a pipe threading traction line 1. A connecting sleeve 4 is installed at the end of the pipe threading traction line 1 extending towards the cable 3. The connecting sleeve 4 is made of rubber and has a connecting groove 5 opened inside it. The cable 3 is connected to the pipe threading traction line 1 by being placed in the connecting groove 5. One end of the pipe threading traction line 1 is connected to a winding device arranged outside. A pipe threading auxiliary device 2 is arranged on the extending trajectory of the pipe threading traction line 1. The pipe threading traction line 1 passes through the pipe threading auxiliary device 2 and is connected to the cable 3 to be threaded. The pipe body that the cable 3 needs to be sleeved outside is arranged in the pipe threading auxiliary device 2, and the pipe threading auxiliary device 2 assists in fixing the pipe body, reducing the force generated on it when the cable 3 passes through and causing it to move synchronously, resulting in a reduction in the pipe threading efficiency, and enhancing the smoothness and pipe threading efficiency of the cable 3 during the pipe threading process.
[0028] The pipe threading auxiliary device 2 includes a main body 21 and sleeves 22 installed at both ends of the main body 21. A through cavity 23 is opened inside the main body 21. The sleeve 22 is composed of a connecting section 221 and a docking section 222. An inner groove 223 for sleeving with the main body 21 is opened inside the connecting section 221. A material passing groove 224 that is communicated with the connecting section 221 and has an inner diameter value equal to the inner diameter value of the through cavity 23 is opened inside the docking section 222. The connecting section 221 wraps its structure around the main body 21 through the inner groove 223. The docking section 222 is connected to the main body 21 and the material passing groove 224 is docked with the through cavity 23. Thread grooves are opened on the outer wall of the main body 21, and threads are protruded on the groove wall of the inner groove 223 to be connected with the main body 21.
[0029] A material-passing ring 24 with different diameters is detachably installed inside the main body 21. The material-passing ring 24 is connected to the through cavity 23 and the butt joint section 222. A limiting groove 26 is also provided on the side wall of the material-passing groove 224. The opening width of the limiting groove 26 on the material-passing groove 224 is smaller than the thickness of the material-passing ring 24. Thus, an annular groove is provided on the side wall of the material-passing ring 24 and is clamped on the groove wall of the limiting groove 26. The outer diameter of the material-passing ring 24 is larger than the inner diameter of the through cavity 23. A clamping groove 25 with a width less than half of the width of the material-passing ring 24 is provided in the through cavity 23. A clamping groove 25 with a width less than half of the width of the material-passing ring 24 is also provided on the material-passing groove 224. A limiting groove 26 is provided on the side wall of the through cavity 23. The sum of the opening depth of the limiting groove 26 on the through cavity 23 and the width of the clamping groove 25 is equal to half of the width of the material-passing ring 24. The material-passing rings 24 provided at the left and right ends are both circular rings. A number of equidistant rubber rings 6 are provided on the inner wall of the material-passing ring 24. However, at the end where the traction force of the pipe-passing traction wire 1 is applied, a blocking ring 7 is installed circumferentially on the inner wall of the material-passing to prevent the problem that the PVC pipe falls off the through-assist device due to the friction force between the PVC pipe and the material-passing ring 24 being less than the friction force between the cable 3 and the PVC pipe, resulting in the failure of pipe passing. A detachable and replaceable material-passing ring is provided inside the main body 21 to limit the pipe body. On the one hand, the diameter of the material-passing ring can be replaced according to the diameter of the sleeve 22. On the other hand, when the main body 21 is connected to the butt joint section 222, it can limit the placed material-passing ring, and further limit the pipe body to be passed through placed in the material-passing ring synchronously, enhancing the pipe-passing efficiency.
