Description

Technical Field

[0001] This utility model relates to the field of auxiliary tool technology, and in particular to a wire-leading tool and wire-leading system. Background Technology

[0002] Electrical modules are common in automobiles, resulting in various wiring requirements. However, the compact structure of a car means that wires and conduits often need to pass through narrow spaces.

[0003] For example, some large trucks often have tire pressure monitoring and inflation devices installed on their wheels to monitor tire pressure and inflate the tires when the pressure is too low or deflate them when the pressure is too high. The wiring for these devices needs to be run from the wheel, through the axle, and connected to the power source. Because the axle opening is narrow, long, and the internal passages are not visible, running the wiring through the axle is not difficult. Similar wiring needs in narrow spaces on trucks are frequently encountered, sometimes requiring the wiring to make 90-degree turns, making wiring inconvenient and inefficient. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a wire-leading tool and wire-leading system that facilitates wiring in narrow spaces.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a wire-leading tool, comprising:

[0006] A guide head, one end of which is provided with a cone and a traction hole, and the other end of which is provided as a connecting end;

[0007] A connector, one end of which is connected to the connecting end of the guide head, and the connector is rotatable 360 ​​degrees relative to the connecting end of the guide head; the other end of the connector is provided with a connecting screw, the outer circumference of which has a first external thread, the first external thread being configured for connecting a wire to be guided.

[0008] Furthermore, a connecting rod is provided at the end of the guide head away from the cone head, and the connecting rod is configured as the connecting end, and the connecting head can rotate 360 ​​degrees relative to the axis of the connecting rod;

[0009] The connector has a mounting hole at one end near the guide head, and the connecting rod passes through the mounting hole and is clearance-fitted with the mounting hole.

[0010] Furthermore, the connecting rod includes a smooth rod section and a threaded section connected together, and the outer periphery of the threaded section has a second external thread, the direction of the second external thread being opposite to the direction of the first external thread;

[0011] The mounting hole includes a connected threaded hole section and a smooth hole section, wherein the threaded hole section is adapted to the second external thread;

[0012] The threaded section passes through the threaded hole section and then enters the smooth hole section, and the threaded section disengages from the threaded hole section, while the smooth rod section is located in the threaded hole section.

[0013] Furthermore, the outer diameter of the threaded section is larger than the diameter of the smooth rod section, and the inner diameter of the smooth hole section is larger than the inner diameter of the threaded hole section;

[0014] The depth of the aperture section is greater than the length of the threaded section, and the length of the smooth rod section is greater than the depth of the threaded hole section.

[0015] Furthermore, the end of the connecting rod away from the cone head is provided with an opening groove, and the mounting hole is provided with an expansion member;

[0016] After the connecting rod passes through the mounting hole, it presses against the expanding member through the opening groove, causing the end of the connecting rod to expand circumferentially to prevent the connecting rod from detaching from the mounting hole.

[0017] Furthermore, the wall of the opening groove is provided with multiple through grooves, which are arranged along the circumference of the connecting rod and penetrate the wall of the opening groove.

[0018] Furthermore, the expanding component is configured as a steel ball.

[0019] Furthermore, the mounting hole includes a small hole segment and a large hole segment that are connected, and the bulging component is located in the large hole segment;

[0020] After passing through the small hole section, the connecting rod extends into the large hole section.

[0021] Furthermore, the guide head has a first column section, the connector head has a second column section, and the second column section and the first column section are coaxially arranged and have the same diameter.

[0022] This utility model also proposes a lead wire system, including:

[0023] The aforementioned lead wire tools;

[0024] A guide rod or guide line is connected to the traction hole.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] In this invention, when it is necessary to thread wires or conduits through a narrow space, the wire guide tool can be used to connect the wire or conduit to the connecting screw of the connector head, and then connect it to the traction hole through a slender guide rod or guide line. By pulling the wire guide tool, the wire or conduit can be threaded through the narrow space (such as a vehicle axle). The connector head can rotate 360 ​​degrees relative to the connecting end of the guide head, which is convenient for passing through small holes and for connecting the wire or conduit to the connecting screw head. During the connection process, the guide head does not need to rotate, only the connector head needs to rotate.

[0027] In this invention, the connecting rod of the guide head and the mounting hole of the connector head are fitted with a clearance, allowing the connector head and the guide head to rotate relative to each other.

[0028] In this invention, one method involves providing a smooth rod section and a threaded section on the connecting rod of the guide head, and a threaded hole section and a smooth hole section in the mounting hole. The threaded section and threaded hole section have reverse threads. When the threaded section screws through the threaded hole section and passes into the smooth hole section, disengaging from the threaded hole, this ensures both the guide head and connector can rotate 360 ​​degrees relative to each other and prevents the connecting rod from detaching from the mounting hole, resulting in a simple overall structure. Another method involves providing an open slot at the end of the connecting rod furthest from the cone, and an expanding member in the mounting hole. After the connecting rod enters the mounting hole, the open slot presses against the expanding member, causing the expanding member to open the open slot, thus preventing the end of the connecting rod from detaching from the mounting hole. This effectively restricts the connecting rod from detaching from the mounting hole, ensuring both the guide head and connector can rotate 360 ​​degrees relative to each other and preventing the connecting rod from detaching from the mounting hole. In other words, the guide head and connector will not detach, resulting in good structural stability. Attached Figure Description

[0044] Example 1:

[0045] like Figures 1-3 As shown, a wire guide tool in this embodiment mainly includes:

[0046] The guide head 1 has a cone 10 at one end, the cross-sectional area of ​​which gradually increases from one end to the other. The cone 10 facilitates the guide head 1 passing through a small hole. The cone 10 also has a traction hole 100 for connecting a traction line or a slender traction rod, so as to facilitate pulling the traction head through the traction line or the slender traction rod. The other end of the guide head 1 (i.e. the end away from the cone 10) is set as a connecting end for connecting to the connecting head 2.

[0047] Connector 2, one end of connector 2 is connected to the connecting end of guide head 1, and connector 2 can rotate 360 ​​degrees relative to the connecting end of guide head 1; the other end of connector 2 is provided with connecting screw 20, the outer periphery of connecting screw 20 has a first external thread 200, the first external thread 200 is configured for connecting the wire to be guided.

[0048] In practical use, when it is necessary to thread wires or conduits in a narrow space, the wire guide tool of this embodiment can be used to first connect the wire or conduit to be threaded to the connecting screw 20 of the connector 2 (generally, the wire or conduit to be threaded needs to have a threaded hole that matches the connecting screw 20 to facilitate detachable fixed connection with the connecting screw 20), and then connect it to the traction hole 100 through a slender guide rod or guide line. Pulling the wire guide tool will cause the wire or conduit to be threaded to pass through the narrow space. The wire guide tool of this embodiment can pass the wire or conduit through a narrow space (such as a vehicle axle). The connector 2 can rotate 360 ​​degrees relative to the connecting end of the guide head 1, which is convenient for passing through small holes and for connecting the wire or conduit to the connecting screw 20. During the connection process, the guide head 1 does not need to rotate, only the connector 2 needs to rotate.

[0049] Specifically, in this embodiment, the end of the guide head 1 away from the cone head 10 is provided with a connecting rod 11, which is configured as a connecting end. The connecting head 2 can rotate 360 ​​degrees relative to the axis of the connecting rod 11. The end of the connecting head 2 near the guide head 1 is provided with a mounting hole 21, through which the connecting rod 11 passes and is clearance-fitted with the mounting hole 21, ensuring a movable connection between the connecting head 2 and the guide head 1, that is, ensuring that the relative 360-degree rotation between the connecting head 2 and the guide head 1 can be realized. Of course, in this embodiment, the positions of the connecting rod 11 and the mounting hole 21 can also be interchanged, that is, the connecting rod 11 is set on the connecting head 2, and the mounting hole 21 is opened on the guide head 1. Since this is only an interchange of the assembly structure of the two, it will not be described in detail here. This embodiment only describes in detail the case where the connecting rod 11 is set on the guide head 1 and the mounting hole 21 is set on the connecting head 2.

[0050] More specifically, in this embodiment, the connecting rod 11 includes a smooth rod section 110 and a threaded section 111 connected together. The outer periphery of the threaded section 111 has a second external thread 111A. The direction of rotation of the second external thread 111A is opposite to that of the first external thread 200. It should be explained that the first external thread 200 is a forward thread, and the second external thread 111A is a reverse thread. The main purpose of this arrangement is to prevent the second external thread 111A from engaging with the threaded hole section 211 of the mounting hole 21 when the wire or conduit to be threaded is screwed onto the first external thread 200 of the connecting screw 20, thus preventing the connecting rod 11 from disengaging from the mounting hole 21. The mounting hole 21 includes a threaded hole section 211 and a smooth hole section 210 connected together. The threaded hole section 211 is adapted to the second external thread 111A, meaning that the internal thread of the threaded hole section 211 is also a reverse thread.

[0051] During assembly, after the threaded section 111 of the connecting rod 11 passes through the threaded hole section 211 and enters the smooth hole section 210, the threaded section 111 disengages from the threaded hole section 211, and the smooth rod section 110 is positioned within the threaded hole section 211. To explain, first, the threaded section 111 of the connecting rod 11 is threaded into the threaded section 111 of the mounting hole 21, and the connecting rod 11 is inserted. After being screwed in to a certain length, the threaded section 111 of the connecting rod 11 disengages from the threaded section 111 of the mounting hole 21 and enters the smooth hole section 210 of the mounting hole 21. At this point, the guide head 1 and the connector head 2 are assembled, effectively ensuring that the guide head 1 and the connector head 2 can rotate 360 ​​degrees relative to each other while preventing them from disengaging.

[0052] In this design, the outer diameter of the threaded section 111 is larger than the diameter of the smooth section 110 because the smooth section 110 needs to have a clearance fit with the mounting hole 21, while the threaded section 111 plays a role in preventing disengagement. The inner diameter of the smooth hole section 210 is larger than the inner diameter of the threaded hole section 211 because the smooth hole section 210 needs to accommodate the threaded section 111, and the threaded hole section 211 corresponds to the smooth section 110. The depth of the smooth hole section 210 is greater than the length of the threaded section 111, and the length of the smooth section 110 is greater than the depth of the threaded hole section 211, ensuring that the connector 2 can rotate freely 360 degrees relative to the connecting rod 113 of the guide head 1, facilitating its passage through the small hole.

[0053] Preferably, the guide head 1 has a first column section 12 and the connector head 2 has a second column section 22. The second column section 22 and the first column section 12 are coaxially arranged and have the same diameter. That is, after the guide head 1 and the connector head 2 are assembled, the first column section 12 and the second column section 22 have the same diameter, ensuring that there is no gap between them and no step is formed. This ensures that the wire guide tool can pass through a narrow space easily and avoids wire interference.

[0054] In this embodiment, by setting a smooth rod section 110 and a threaded section 111 on the connecting rod 11 of the guide head 1, and setting a threaded hole section 211 and a smooth hole section 210 on the mounting hole 21, the threaded section 111 and the threaded hole section 211 are reverse threads. When the threaded section 111 screws through the threaded hole section 211 and passes through the smooth hole section 210, and disengages from the threaded hole, it ensures that the guide head 1 and the connecting head 2 can rotate 360 ​​degrees relative to each other, and also ensures that the connecting rod 11 will not disengage from the mounting hole 21, and the overall structure is simple.

[0055] Example 2:

[0056] like Figures 4-6 As shown, a wire guide tool in this embodiment mainly includes:

[0057] The guide head 1 has a cone 10 at one end, the cross-sectional area of ​​which gradually increases from one end to the other. The cone 10 facilitates the guide head 1 passing through a small hole. The cone 10 also has a traction hole 100 for connecting a traction line or a slender traction rod, so as to facilitate pulling the traction head through the traction line or the slender traction rod. The other end of the guide head 1 (i.e. the end away from the cone 10) is set as a connecting end for connecting to the connecting head 2.

[0058] Connector 2, one end of connector 2 is connected to the connecting end of guide head 1, and connector 2 can rotate 360 ​​degrees relative to the connecting end of guide head 1; the other end of connector 2 is provided with connecting screw 20, the outer periphery of connecting screw 20 has a first external thread 200, the first external thread 200 is configured for connecting the wire to be guided.

[0059] It should be explained that the main difference between this embodiment and Embodiment 1 lies in the connection method between the guide head 1 and the connector head 2. However, in this embodiment, the connector head 2 can still rotate 360 ​​degrees relative to the connecting end of the guide head 1, and the connection between the guide head 1 and the connector head 2 can be prevented from becoming loose. That is, in this embodiment, the structure of the connecting rod 11 of the guide head 1 and the structure of the mounting hole 21 of the connector head 2 are different from those in Embodiment 1, while other structures are basically the same.

[0060] Specifically, in this embodiment, the end of the connecting rod 11 away from the cone head 10 is provided with an opening groove 112. This opening groove 112 can be processed by drilling. An expansion member 3 is provided in the mounting hole 21. The function of the expansion member 3 is to expand the opening groove 112, thereby causing the end of the connecting rod 11 away from the cone head 10 to expand outward. In this way, this end of the connecting rod 11 can effectively play a role in preventing loosening. In the actual assembly process, after the connecting rod 11 of the guide head 1 passes through the mounting hole 21, it presses against the expansion member 3 through its opening groove 112. The expansion member 3 causes the end of the connecting rod 11 to expand outward in its own circumference. The maximum external dimension of the end of the connecting rod 11 is already larger than the diameter of the opening (small hole segment 213) of the mounting hole 21, so as to restrict the connecting rod 11 from detaching from the mounting hole 21.

[0061] The opening groove 112 has multiple through grooves 113 on its wall. For example, in this embodiment, four through grooves 113 can be evenly distributed around the circumference of the opening groove 112. The multiple through grooves 113 are arranged around the circumference of the connecting rod 11 and penetrate the wall of the opening groove 112. The opening groove 112 facilitates the expansion member 3 to expand the end of the connecting rod 11. In this embodiment, the expansion member 3 is a steel ball, which has a simple structure and is easy to use. Of course, the expansion member 3 can also be a conical member. The opening groove 112 presses against the conical surface of the conical member, and the conical surface expands the end of the connecting rod 11 outward. However, considering cost factors, using a steel ball as the expansion member 3 is the preferred solution.

[0062] Furthermore, in this embodiment, the mounting hole 21 includes a small hole section 213 and a large hole section 212 that are connected, and the expansion member 3 is located in the large hole section 212; after the connecting rod 11 passes through the small hole section 213, it extends into the large hole section 212 and presses against the expansion member 3.

[0063] In this embodiment, an opening groove 112 is provided at the end of the connecting rod 11 away from the cone head 10, and an expansion member 3 is provided in the mounting hole 21. After the connecting rod 11 passes through the mounting hole 21, it presses against the expansion member 3 through the opening groove 112. The expansion member 3 opens the opening groove 112, so that the end of the connecting rod 11 opens circumferentially. This can effectively restrict the connecting rod 11 from detaching from the mounting hole 21. This ensures that the guide head 1 and the connecting head 2 can rotate 360 ​​degrees relative to each other, and also ensures that the connecting rod 11 will not detach from the mounting hole 21. That is, the guide head 1 and the connecting head 2 will not detach, resulting in good structural stability.

[0064] When the lead-in tool from Embodiment 1 or Embodiment 2 is applied to the lead-in system, the lead-in system includes: the lead-in tool from Embodiment 1 or Embodiment 2, and a guide rod or guide wire connected in the traction hole 100. In actual use, it can also be used in conjunction with a magnet to facilitate the guide rod or guide wire passing through the target position.

[0065] In this solution, the wire guide tool facilitates wiring in narrow spaces, ensuring convenient and efficient wiring with a simple overall structure.
