[0025] Example
[0026] like Figure 1-2As shown, the utility model proposes an easily fixed PVC threading tube, comprising a right-angled PVC threading tube 1, a wiring assembly for driving the wire to pass through the right-angled inner wall is installed at a right-angle position in the right-angled PVC threading tube 1, the wiring assembly comprises a rotating shaft 2 rotatably installed at a right-angle position of the right-angled PVC threading tube 1, a disk 3 is fixedly sleeved on the rotating shaft 2, an arc strip 4 is hinged on the curved surface of the disk 3, a spring 5 is fixed between the arc strip 4 and the curved surface of the disk 3, one end of the rotating shaft 2 extends to the right-angled PVC threading tube 1, and the rotating shaft 2 is fixedly sleeved with a disk 3, and the curved surface of the disk 3 is hinged with a disk 3. A spring 5 is fixed between the curved surface of the disk 3 and the curved surface of the disk 3. A rotating wheel 6 is fixed to the outside of the C threading tube 1. The rotating wheel 6 is manually rotated to rotate the rotating shaft. The manual rotation of the rotating wheel 6 drives the rotating shaft 2 to rotate, so that the side of the arc-shaped bar 4 away from the disc 3 contacts and squeezes the spring 5. The anti-skid pattern on the arc-shaped bar 4 makes the arc-shaped bar 4 rub against the surface of the wire. As the arc-shaped bar 4 rotates with the disc 3, the friction force provides a thrust to one end of the wire, prompting the wire to pass through the right-angle position of the right-angle PVC threading tube 1, and assisting the wire to pass through the right-angle PVC threading tube more smoothly.
[0027] Among them, the distance between the curved strip 4 and the curved surface of the disk 3 increases along its arc direction, and the distance between the curved strip 4 and the inner wall of the right-angled PVC threading tube 1 decreases along the arc direction. In the process of the curved strip 4 rotating relative to the disk 3, the resistance in the process of contacting with the wire will become greater and greater, and the deformation of the spring 5 will also be greater, so that the friction between the curved strip 4 and the wire will also increase, providing greater thrust, having a compressible space, and being able to better adapt to the friction generated by wires of different thicknesses.
[0028] In addition, the arc strip 4 is a rubber strip, and one side of the arc strip 4 is provided with anti-skid patterns, and the surface roughness of the arc strip 4 is increased by the anti-skid patterns.
[0029] Further, the rotating wheel 6 is provided with a marking pointer 7, which is located directly above the arc strip 4. By the position of the marking pointer 7 corresponding to the arc strip 4, the position of the arc strip 4 in the right-angled PVC threading tube 1 can be known externally, which is convenient for operation.
[0030] like Figure 2-3 As shown, a positioning mechanism for fixing the position of the right-angled PVC threading tube 1 is provided on both sides of the right-angled PVC threading tube 1. The positioning mechanism includes a storage groove 8 fixed on both sides of the right-angled PVC threading tube 1, a track rod 9 is hinged in one end of the storage groove 8, a slide groove is provided on the track rod 9, and a positioning pin 10 is slidably installed in the slide groove. When not in use, the positioning pin 10 is stored in the slide groove, and the track rod 9 is stored in the storage groove 8, which is convenient for carrying and transportation, and avoids the positioning pin 10 being exposed to the outside world and causing accidental injury during use.
[0031] It is worth noting that a limit block 12 is fixed in the slide groove on the track rod 9, and a sliding hole is provided on the limit block 12. One end of the positioning pin 10 slides through the sliding hole, and the sliding hole provides a movement guide for the positioning pin 10. A protrusion 11 is fixed at one end of the positioning pin 10, and the protrusion 11 is manually pushed to drive the positioning pin to move. The other end of the positioning pin 10 is set in a conical structure, and one end of the conical structure is used to insert into the soil, thereby fixing the position of the right-angle PVC threading tube, facilitating the threading work, and the right-angle PVC threading tube will not move at will during the threading process.
[0032] Working principle: After the right-angle PVC wire threading tube is placed in the embedded groove in the soil, manually pull the track rod 9 out of the storage groove 8, and push the protrusion by hand to drive the positioning nail 10 to slide in the slide groove so that one end of the positioning nail 10 is inserted into the side wall of the embedded groove, thereby fixing the position of the right-angle PVC wire threading tube 1, facilitating the threading work, and the right-angle PVC wire threading tube 1 will not move at will during the threading process.
[0033] The wire itself has a certain hardness. The wire is fed into the right-angle PVC threading tube. When resistance is encountered when continuing to feed the wire, it means that the end of the wire has reached the right-angle position of the right-angle PVC threading tube. Then the wheel 6 is manually turned to drive the rotating shaft 2 to rotate, so that the side of the arc strip 4 away from the disc 3 contacts and squeezes the spring 5, and the anti-slip grooves on the arc strip 4 make the arc strip 4 rub against the surface of the wire. As the arc strip 4 rotates with the disc 3, the friction force provides a thrust to one end of the wire, prompting the wire to pass through the right-angle position of the right-angle PVC threading tube 1, helping the wire to pass through the right-angle PVC threading tube more smoothly, thereby improving functionality.
[0034] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
