Description

Technical Field

[0001] The utility model relates to the field of tooling, in particular to a pipe orifice threading tool. Background Art

[0002] To isolate the wires from the outside, they are usually covered with pipe fittings for protection. Pipe fittings are divided into open pipes and closed pipes (enclosed tube bodies). Open pipes have gaps in the pipe wall, so although threading is easy, in order to achieve waterproof and dustproof effects, the wires passing through the pipe need to be fully wrapped with tape. If you only want to use the tape wrapping method to save costs, you need to choose closed pipes, but closed pipes will encounter some difficulties when threading the wires.

[0003] Because the wall of the closed-end tube is a fully enclosed structure, it is impossible to thread the wires in the conventional way. When the wires are long, a longer tube body is required, and the wires are difficult to directly pass through the tube body, especially for softer low-voltage wires. When using closed-end tubes, workers can only thread the wires manually. This primitive method is time-consuming and labor-intensive, which will have a great impact on production operations and greatly reduce efficiency. Utility Model Content

[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0024] Please refer to Figures 1 to 3 A pipe threading tool is used to thread a wire harness 4 into a closed pipe body 3, including a magnetic guide component 1 and a pipe threading component 2, wherein the pipe threading component 2 includes a ferromagnetic part 21 and a fixed part 22, wherein the fixed part 22 is used to fix the wire harness 4, the ferromagnetic part 21 and the fixed part 22 are connected, and at least part of the surface of the ferromagnetic part 21 is a smooth surface; the magnetic guide component 1 uses magnetic force to drive the ferromagnetic part 21 to move.

[0025] From the above description, it can be seen that the beneficial effect of the utility model is that: a pipe threading tool is provided, the pipe threading component 2 connecting the wire harness 4 is placed into the wire inlet of the closed pipe body 3, and the magnetic guide component 1 is used outside the pipe body 3 to guide the ferromagnetic part 21 of the pipe threading component 2, so that the magnetic guide component 1 is moved outside the pipe to move the pipe threading component 2 inside the pipe body 3, and then the wire harness 4 is passed through the pipe body 3, without manual threading, thereby improving the threading efficiency of the closed pipe body 3.

[0026] In some embodiments, the magnetic guide assembly 1 includes a first magnet 11, a second magnet 12, and a connecting frame 13. The end surfaces of the first magnet 11 and the second magnet 12 with different magnetic poles are arranged opposite each other, and the connecting frame 13 connects the first magnet 11 and the second magnet 12. The two magnets are arranged at both ends of the tube 3 to respectively generate magnetic fields, so that the ferromagnetic portion 21 located inside the tube 3 is more stably guided by the magnetic force, thereby improving the threading speed.

[0027] Specifically, the connecting frame 13 includes a telescopic portion 131 and two connecting rods 132. The two connecting rods 132 are provided at opposite ends of the telescopic portion 131 and are respectively connected to the first magnet 11 and the second magnet 12. The telescopic portion 131 is used to control the distance between the first magnet 11 and the second magnet 12. To accommodate pipes 3 of different diameters, the telescopic portion 131 is provided on the connecting frame 13 to control the distance between the magnetic poles of the first magnet 11 and the second magnet 12. The spacing between the first magnet and the second magnet is controlled according to the actual diameter of the pipe to be penetrated.

[0028] Preferably, the telescopic portion 131 includes a first sleeve 1311 and a second sleeve 1312. The outer diameter of the first sleeve 1311 is smaller than the inner diameter of the second sleeve 1312. The first sleeve 1311 is sleeved onto the second sleeve 1312. The first sleeve 1311 and the second sleeve 1312 are respectively connected to the connecting rod 132. Providing two sleeves nested with each other as the telescopic portion 131 has a simple structure, is easy to produce, and facilitates immediate adjustment by the operator.

[0029] In some embodiments, the telescopic portion 131 further includes a latch 1313, and the first sleeve 1311 and the second sleeve 1312 are each provided with at least two limiting holes that match the cross-sectional shape of the latch 1313. The latch 1313 is used to limit the degree of nesting between the first sleeve 1311 and the second sleeve 1312, thereby ensuring that the distance between the first magnet 11 and the second magnet 12 remains stable during the pipe threading process, avoiding sudden changes in the distance that affect the process. At the same time, at least two limiting holes are provided on the first sleeve 1311 and the second sleeve 1312, respectively, to control the distance between the first magnet 11 and the second magnet 12 and make level restrictions, so that the staff can conveniently select the appropriate hole position to limit the distance between the two magnets according to the actual working standards.

[0030] In some embodiments, the telescopic portion 131 further includes a latch 1313. The first sleeve 1311 has a stopper hole that matches the cross-sectional shape of the latch 1313, and the second sleeve 1312 has at least two stopper holes that match the cross-sectional shape of the latch 1313. Providing a stopper hole on the first sleeve 1311 allows the first sleeve 1311 to serve as a reference element and the second sleeve 1312 to serve as a variable element when changing the distance between the two magnets, making it easier to control the distance between the two magnets.

[0031] In some embodiments, the connecting rod 132 includes a bent section, and the two bent sections of the connecting rod 132 are respectively connected to the first magnet 11 and the second magnet 12. The bent section is provided on the connecting rod 132 to connect the two magnets, thereby freeing up space between the opposing poles of the two magnets to facilitate the placement of the tube 3. Specifically, the bent section can be angled or curved.

[0032] In some embodiments, the ferromagnetic portion 21 includes a threading end and a connecting end provided on different end surfaces, wherein at least a portion of the threading end is an arcuate surface, and the connecting end is connected to the fixing portion 22. Because the interior of some tube bodies 3 is rough or has wrinkles, such as corrugated tubes, a ferromagnetic portion 21 with an arcuate surface is provided to improve the smoothness of the tube threading process, thereby preventing the tube from getting stuck during the threading process.

[0033] In some embodiments, the fixing portion 22 is a fixing hoop or a soft rope. The wiring harness 4 is fixed by the expansion and contraction of the fixing hoop or the wiring harness 4 is tightened by the soft rope, which simplifies the connection between the fixing portion 22 and the wiring harness 4 and improves the convenience of operation.

[0034] Please refer to Figure 4 In some embodiments, the magnetic guide assembly 1 is an annular magnet. When threading a pipe with a fixed diameter, the annular magnet is used as a magnetic guide, and the pipe 3 is passed through the hollow portion of the annular magnet. This eliminates the need to control the distance between the magnets and improves operational fluidity. Preferably, the difference between the inner diameter of the annular magnet and the outer diameter of the pipe 3 is controlled between 10 and 20 cm.

The magnetic guide assembly 1 uses magnetic force to move the ferromagnetic portion 21. The pipe threading assembly 2 connected to the wire harness 4 is placed into the wire inlet of the closed pipe body 3. The magnetic guide assembly 1 is used to guide the ferromagnetic portion 21 of the pipe threading assembly 2 from the outside of the pipe body 3. By moving the magnetic guide assembly 1 outside the pipe, the pipe threading assembly 2 moves inside the pipe body 3, thereby threading the wire harness 4 into the pipe body 3.

The telescopic portion 131 includes a first sleeve 1311 and a second sleeve 1312. The first sleeve 1311 has a smaller diameter than the second sleeve 1312 and is sleeved onto the second sleeve 1312. The first sleeve 1311 and the second sleeve 1312 are each connected to the connecting rod 132. The arrangement of two nested sleeves as the telescopic portion 131 simplifies the structure, is easy to manufacture, and facilitates immediate adjustment by the operator.

[0040] The connecting rod 132 includes a bent section, and the bent sections of the two connecting rods 132 are respectively connected to the first magnet 11 and the second magnet 12. The bent section is provided on the connecting rod 132 to connect the two magnets, thereby freeing up space between the opposing poles of the two magnets to facilitate the placement of the tube 3.

[0044] Based on the first embodiment, the ferromagnetic portion 21 includes a threading end and a connecting end located on different end surfaces. The threading end is at least partially curved, and the connecting end is connected to the fixing portion 22.
