At present, the prior art provides a variety of cable fixings, which can not only ensure the stable laying of cables, but also lock them to the inner wall of the pipeline through a fixed structure to provide stability requirements when the cables stop moving.

[0003] However, these conventional fixing devices generally have the problems of complicated structure and high manufacturing cost. In addition, their fixing structures mostly rely on manual operation to open, which is time-consuming and labor-intensive, and reduces the overall work efficiency. Summary of the invention

[0006] Preferably, the wire tube is a ferrous part, and the driving structure includes a magnetic part embedded in the movable sleeve and a coil wound on the outer peripheral wall of the wire tube. A blocking part is also provided on the outer peripheral wall of the wire tube. When the connecting part and the connecting fitting are in a locked state and the coil is not energized, one end of the movable sleeve abuts against the blocking part, and there is a magnetic attraction force between the magnetic part and the blocking part; when the coil is energized, there is a magnetic repulsion force between the magnetic part and the blocking part, so that the movable sleeve moves away from the blocking part and the connecting part and the connecting fitting are in a released state.

[0007] Preferably, the movable sleeve comprises an annular sleeve body, the sleeve body is provided with an axial hole for connecting with the second joint and a first accommodating groove surrounding the outer side of the axial hole, and the magnetic member is embedded in the first accommodating groove.

[0021] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0022] This embodiment discloses a movably positioned threading device for fixing cables, for example, for fixing cables in oil well pipelines. Since the oil well pipeline moves up and down in the oil well, the cables therein also move. When the pipeline stops, the cables also need to be fixed in the position to prevent the cables from falling under the action of gravity when there is no operation. Therefore, the threading device needs to have a self-fixing function.

[0023] In this regard, Figures 1 to 4 The threading device in this embodiment includes a wire tube 1 for allowing the cable to pass through, a support member 2 and a driving structure.

[0024] A first joint 40 and a second joint 41 of a tubular structure are respectively provided at both ends of the wire tube 1, wherein the first joint 40 of one threading device is detachably connected to the second joint 41 of another threading device, so that several threading devices can be connected together end to end.

[0025] The support member 2 includes a first end 20 and a second end 21. The first end 20 is pivotally connected to the first joint 40 via the pivot structure 8, so that the second end 21 has an open state away from the wire tube 1 (such as Figure 3 ) and the closed state near the wire tube 1 (such as Figure 1 ). In the closed state, the support member 2 is attached to the wire tube 1, and the support member 2 is parallel to the axis of the wire tube 1, so that the wire tube 1 can move freely. In the open state, the second end 21 of the support member 2 extends to the outside of the wire tube 1 and abuts against the supporting surface outside the wire tube 1 (such as the inner wall of the pipe), thereby limiting the movement of the wire tube 1.

[0026] Furthermore, the pivot structure 8 constantly provides the support member 2 with a rotational driving force to move the second end 21 away from the wire tube 1 , so when the second end 21 is not restricted, the support member 2 automatically enters the open state.

[0027] A movable sleeve 5 is sleeved on the outer peripheral wall of the second joint 41, and a connecting piece 60 is arranged on the movable sleeve 5. A connecting fitting 61 is arranged on the second end 21 of the support member 2. The connecting piece 60 is locked and connected with the connecting fitting 61.

[0028] The movable sleeve 5 can move along the axial direction of the second joint 41 to make the connection fitting 61 and the connection member 60 in a locked or unlocked state. When the connection fitting 61 and the connection member 60 are in the locked state, the second end 21 is locked and cannot enter the open state. When the connection fitting 61 and the connection member 60 are in the unlocked state, the second end 21 automatically extends.

[0029] The driving structure is used to drive the movable sleeve 5 to move along the second joint 41 .

[0030] For the threading device in this embodiment, when in use, the cable is threaded into the wire tube 1 to fix the cable. In addition, the support member 2 has an open state and a closed state. When in the closed state, the wire tube 1 can move freely according to the cable. When the cable is moved into place and needs to be fixed in the current position, the support member 2 is automatically driven by the driving structure to enter the open state, so that the second end 21 of the support member 2 extends out of the wire tube 1 and abuts against the supporting surface (such as the inner wall of the oil well pipeline), thereby fixing the wire tube 1 in this position. It can be seen that the above-mentioned threading device not only provides the basic cable fixing function, but also provides the function of automatically fixing the threading device in a certain position, which is easy to use and saves labor.

[0031] On the other hand, the wire tube 1 is a ferrous part, that is, the ferrous part is a device that can be adsorbed by a magnet or generate magnetism under the action of an electronic coil.

[0032] The driving structure includes a magnetic member 30 embedded in the movable sleeve 5 and a coil (not shown) wound on the outer peripheral wall of the wire tube 1. A blocking portion 10 is also provided on the outer peripheral wall of the wire tube 1. Specifically, the blocking portion 10 is a skirt extending outward from the outer peripheral wall of the wire tube 1.

[0033] When the connecting member 60 and the connecting fitting 61 are in a locked state and the coil is not energized, one end of the movable sleeve 5 abuts against the blocking part 10, and there is a magnetic attraction force between the magnetic member 30 and the blocking part 10. Under the action of the magnetic attraction force, the movable sleeve 5 remains in this position, so that the connecting member 60 and the connecting fitting 61 remain in a locked state.

[0034] When the coil is energized, the wire tube 1 generates a magnetic field, the direction of the magnetic force of which is opposite to the direction of the magnetic force of the magnetic part 30. Therefore, there is a magnetic repulsion between the magnetic part 30 and the blocking part 10. Under the action of the magnetic repulsion, the movable sleeve 5 moves away from the blocking part 10, so that the connecting part 60 and the connecting mating part 61 are in a released state, thereby automatically opening the support part 2.

[0035] Specifically, Figure 5 The movable sleeve 5 includes an annular sleeve body 50 , in which an axial hole 51 for connecting with the second joint 41 and a first accommodating groove 52 surrounding the outer side of the axial hole 51 are arranged, and the magnetic member 30 is embedded in the first accommodating groove 52 .

[0036] In addition, as the distance between the movable sleeve 5 and the blocking part 10 becomes farther, the magnetic repulsion between the magnetic part 30 and the blocking part 10 becomes smaller. Therefore, in order to ensure that the connecting part 60 is separated from the connecting fitting 61, a second accommodating groove 53 surrounding the outside of the first accommodating groove 52 is also provided in the sleeve body 50, and an elastic part 9 is provided in the second accommodating groove 53. The elastic part 9 is used to provide the movable sleeve 5 with an elastic driving force in the same direction as the magnetic repulsion.

[0037] In this embodiment, as the magnetic attraction between the magnetic part 30 and the blocking part 10 disappears and turns into a magnetic repulsion in the opposite direction, the movable sleeve 5 moves away from the blocking part 10 under the combined action of the magnetic repulsion and the elastic restoring force to ensure that the movable sleeve 5 moves to the position where the connecting part 60 is separated from the connecting mating part 61.

[0038] On the other hand, a yoke sleeve 7 is sleeved on the outer peripheral wall of the wire tube 1, and a containing space K is defined between the inner wall of the yoke sleeve 7 and the outer wall of the wire tube 1, and the coil is located in the containing space K. The magnetic lines of force generated by the electronic coil are enclosed in the containing space K by the yoke sleeve 7 to prevent the magnetic lines of force from leaking out, thereby ensuring the strength of the magnetic repulsion force.

[0039] On the other hand, the connecting member 60 is a locking hook, and the connecting fitting 61 is a locking hole. When the movable sleeve 5 moves toward the blocking portion 10, the locking hook automatically enters the locking hole to lock the support member 2 and the movable sleeve 5 together. On the contrary, when the movable sleeve 5 moves away from the blocking portion 10, the locking hook withdraws from the locking hole, thereby unlocking the support member 2. It should also be noted that manual operation is required to push the movable sleeve 5 toward the blocking portion 10 to lock the support member 2 and the movable sleeve 5.

[0040] On the other hand, the pivot structure 8 includes a pivot shaft and a torsion spring disposed on the pivot shaft, and the torsion spring provides a driving force for the support member 2 to expand laterally outward.

[0041] like Figure 4 A plurality of independent wire holes 11 are arranged in the second connector 41 at intervals to prevent the cables in the wiring harness from being entangled with each other.

[0042] On the other hand, the first connector 40 of one threading device is threadedly connected to the second connector 41 of another threading device, thereby facilitating the connection and disassembly between the multiple threading devices.

[0043] Furthermore, the first connector 40 and the second connector 41 are respectively threadedly connected to two ends of the wire tube 1 to facilitate the assembly of the wire threading device.

[0044] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
