[0021] In order to make the technical content, structural features, achieved purposes and effects of the present application clear, the following will be described in detail in combination with the embodiments and the accompanying drawings.

[0022] The present embodiment discloses a movable and positionable threading device for fixing a cable, for example, for fixing a cable in an oil well pipe. Since the oil well pipe moves up and down in the oil well, the cable in the pipe also moves. When the pipe stops, the cable also needs to be fixed at the position to avoid falling under the action of gravity without operation. Therefore, the threading device needs to have a self-fixing function.

[0023] To this end, as Figures 1 to 4 the threading device in the present embodiment includes a wire tube 1 for the cable to pass through, a support member 2 and a driving structure.

[0024] ​​The two ends of the wire tube 1 are respectively provided with a first joint 40 and a second joint 41 in a tubular structure, and the first joint 40 of one wire threading device is detachably connected with the second joint 41 of another wire threading device, so that several wire threading devices can be connected together in a head-to-tail manner.

[0025] The support 2 comprises a first end 20 and a second end 21. The first end 20 is pivotally connected with the first joint 40 through a pivot structure 8, so that the second end 21 has an open state (as shown in Figure 3 ) away from the wire tube 1 and a closed state (as shown in Figure 1 ) close to the wire tube 1. In the closed state, the support 2 is attached to the wire tube 1, and the support 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 2 extends to the outside of the wire tube 1 and abuts against a support surface (such as the inner wall of a pipeline) outside the wire tube 1, thereby limiting the movement of the wire tube 1.

[0026] If the pivot structure 8 always provides a rotation driving force for the support 2 to move the second end 21 away from the wire tube 1, then when the second end 21 is not limited, the support 2 automatically enters the open state.

[0027] An active sleeve 5 is sleeved on the outer peripheral wall of the second joint 41, and the active sleeve 5 is provided with a connecting piece 60. The second end 21 of the support 2 is provided with a connecting matching piece 61. The connecting piece 60 and the connecting matching piece 61 are locked and connected.

[0028] The active sleeve 5 can move along the axial direction of the second joint 41, so that the connecting matching piece 61 and the connecting piece 60 are in a locked or released state. When the connecting matching piece 61 and the connecting piece 60 are in the locked state, the second end 21 is locked and cannot enter the open state. When the connecting matching piece 61 and the connecting piece 60 are in the released state, the second end 21 automatically extends.

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

[0030] For the wire threading device in the embodiment, when in use, the cable is threaded into the wire tube 1 to fix the cable. In addition, the support 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, and when the cable needs to be fixed at the current position after moving to the position, the support 2 is automatically actuated by the driving structure to enter the open state, so that the second end 21 of the support 2 extends to the outside of the wire tube 1 and abuts against a support surface (such as the inner wall of a petroleum well pipeline), thereby fixing the wire tube 1 at the position. It can be seen that the above-mentioned wire threading device not only provides the basic cable fixing function, but also provides the function of automatically fixing the wire threading device at a certain position, which is convenient to use and saves labor.

[0031] On the other hand, the wire tube 1 is a ferrous member, i.e. a member that can be attracted by a magnet or that can generate a magnetic field under the action of an electronic coil.

[0032] The driving structure comprises the magnetic member 30 embedded in the movable sleeve 5 and a coil (not shown in the figure) wound on the outer peripheral wall of the wire tube 1, and a blocking portion 10 is further 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 mating member 61 are in the locked state and the coil is not energized, one end of the movable sleeve 5 abuts against the blocking portion 10, and there is a magnetic attraction force between the magnetic member 30 and the blocking portion 10, under the action of which the movable sleeve 5 is kept in the position, so that the connecting member 60 and the connecting mating member 61 are kept in the 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 that of the magnetic member 30, so that there is a magnetic repulsion force between the magnetic member 30 and the blocking portion 10, under the action of which the movable sleeve 5 moves away from the blocking portion 10, so that the connecting member 60 and the connecting mating member 61 are in the unlocked state, thereby automatically opening the support member 2.

[0035] Specifically, as shown in the figure, Figure 5 The movable sleeve 5 comprises an annular sleeve body 50, an axial hole 51 for connecting with the second connector 41 is provided in the sleeve body 50, and a first accommodating groove 52 is provided outside the axial hole 51, 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 portion 10 becomes farther, the magnetic repulsion force between the magnetic member 30 and the blocking portion 10 becomes smaller, so that, in order to ensure the separation of the connecting member 60 and the connecting mating member 61, a second accommodating groove 53 is further provided outside the first accommodating groove 52 in the sleeve body 50, and an elastic member 9 is provided in the second accommodating groove 53, which is used to provide the movable sleeve 5 with an elastic driving force in the same direction as the magnetic repulsion force.

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

[0038] On the other hand, a yoke sleeve 7 is sleeved on the outer peripheral wall of the wire tube 1, and there is an accommodating space K 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 accommodating space K. Through the yoke sleeve 7, the magnetic lines generated by the electronic coil are enclosed in the accommodating space K, avoiding the leakage of the magnetic lines, thereby ensuring the strength of the magnetic repulsion force.

[0039] On the other hand, the connecting member 60 is a hook, and the connecting mating member 61 is a lock hole. When the movable sleeve 5 moves towards the blocking part 10, the hook automatically enters the lock hole, and the support member 2 is locked with the movable sleeve 5. On the contrary, when the movable sleeve 5 moves away from the blocking part 10, the hook exits from the lock hole, and the support member 2 is unlocked. It is necessary to manually push the movable sleeve 5 towards the blocking part 10 to lock the support member 2 with the movable sleeve 5.

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

[0041] As Figure 4 A plurality of independent wire holes 11 are arranged in the second joint 41 to avoid the entanglement of each wire cable in the wire harness.

[0042] On the other hand, the first joint 40 of one wire penetrating device is screwed with the second joint 41 of another wire penetrating device, so as to facilitate the connection and disassembly between the wire penetrating devices.

[0043] Furthermore, the first joint 40 and the second joint 41 are respectively screwed with the two ends of the wire tube 1, so as to facilitate the assembly of the wire penetrating device.

[0044] The above only discloses the preferred embodiments of the present application, and of course cannot limit the scope of the present application. Any equivalent changes made within the scope of the patent application of the present application are still within the scope of the present application.
