[0068] Working process and technical principle of the present invention:

[0069] 1. Preparation

[0070] like Figure 2 As shown, first place the spherical probe (700) into the threading area. The shape of the threading area is not particularly limited, for example, it can be a tubular area, a box-shaped area, etc. At the same time, place the wires (wires to be threaded) in the protective tube (600).

[0071] 2. Threading

[0072] The driving motor (410) of the friction wheel (400) is started to drive the friction wheel (400) to start rotating. The relative distance between the friction wheel (400) and the threaded tube (500) is adjusted by using the adjustment rod (300). When the friction wheel (400) contacts the threaded tube (500), due to the friction force between the two, the rotating friction wheel (400) drives the threaded tube (500) to rotate. Since the threaded tube (500) is threadedly connected to the fixed nut (210) at a fixed position, the threaded tube (500) moves when rotating, so that the threaded tube (500) rotates while continuously moving forward to enter and pass through the threading area (for example, it rotates forward in the forward direction to enter the threading area, and then rotates backward in the reverse direction to exit the threading area), and then carries the protective tube (600) and the wire (the wire to be threaded) through the threading area. Then, the spherical probe (700) and the protective tube (600) are disassembled to remove the wire (the wire to be threaded), and finally the threading work is completed.

[0073] In actual operation, the operator can select the best operation method according to the actual work requirements, such as using the continuously variable transmission (420) to select the best rotation speed of the driving motor (410), using the adjustment rod (300) to select the best relative distance between the friction wheel (400) and the threaded tube (500), using the multi-section threaded tube to assemble the best length of the threaded tube (500), using the sliding slot and the positioning bolt (310) to select the best position of the driving motor (410), using the lifting support column (110) to select the best height of the lifting platform (100), etc., so as to complete the threading work faster and better;

[0074] Of course, the present invention can make use of all available existing technologies, for example, selecting more suitable preparation materials for the threaded tube (500) and the protective tube (600), adding a wire pay-off reel, setting a camera on the spherical probe (700), etc. These changes all fall within the protection scope of the present invention.

[0075] Beneficial technical effects and analysis of the present invention:

[0076] According to an embodiment of the present invention, Figure 1 As shown, the automatic inner wire threader for power distribution of the present invention has several unique designs as described below, thereby achieving its corresponding unique technical effects:

[0077] 1. Since the rotating friction wheel (400) drives the threaded tube (500) to rotate through friction, and since the threaded tube (500) is threadedly connected to the fixed nut (210) at a fixed position, the threaded tube (500) rotates while continuously moving forward to enter and pass through the threading area, and then carries the protective tube (600) and the wire (wire to be threaded) through the threading area, and finally completes the threading work.

[0078] 2. The relative distance between the friction wheel (400) and the threaded tube (500) can be adjusted by using the adjustment rod (300), so the friction between the two can be adjusted, so that the rotation speed of the threaded tube (500) can be effectively controlled and adjusted, and the speed of the threaded tube (500) passing through the threading area can be changed, and the threading speed can be accurately controlled. Therefore, it can meet the needs of various operation scenes.

[0079] 3. Place the wires (wires to be threaded) in the protective tube (600). The protective tube (600) can effectively protect the wires (wires to be threaded) and prevent the wires (wires to be threaded) from being worn or damaged.

[0080] 4. The spherical surface of the spherical probe (700) can increase the smoothness, making the operation of passing through the threading area smoother and smoother.

[0081] The diameter of the spherical probe (700) is larger than the diameter of the threaded tube (500), which can prevent the threaded tube (500) from rubbing against the threading area (such as the tube wall) when rotating, thereby effectively preventing both the threaded tube (500) and the threading area from being damaged.

[0082] 5. The spherical probe (700) is detachably connected to the end of the threaded tube (500). There are multiple spherical probes (700) with different diameters. This design has two advantages:

[0083] Firstly, the disassembly of the spherical probe (700) becomes very convenient and quick;

[0084] Secondly, since the diameters of the spherical probe (700) are different, the most suitable spherical probe (700) can be selected according to different conditions of the threading area. For example, according to the specific size of the threading area (the diameter of the pipe), the spherical probe (700) of the most suitable size can be selected, thereby achieving the best threading effect, saving time and effort.

[0085] This is very important because: the inventors found in their research that: for pipes with large diameters, if a spherical probe (700) of too small size is selected, the threading speed will be slow, and for pipes with small diameters, if a spherical probe (700) of too large size is selected, the threading speed will also be slow. Only when the difference between the size of the spherical probe (700) and the size of the threaded pipe (500) is within a certain range, the threading speed can be maintained at the fastest.

[0086] 6. The lifting support column (110) can be used to select the most suitable height of the lifting platform (100), so as to complete the threading work faster and better.

[0087] 7. According to the different span requirements of the threading area, the threaded pipe (500) of corresponding length can be assembled by using multiple sections of threaded pipes, which has wide adaptability.

[0088] 8. Two friction wheels (400) are symmetrically distributed on both sides of the threaded tube (500), which can not only more efficiently drive the threaded tube (500) to rotate by squeezing from both sides at the same time, but also effectively prevent the threaded tube (500) from deviating during rotation.

[0089] 9. Furthermore, the best position of the drive motor (410) can be selected by using the sliding slot and the positioning bolt (310), the best speed of the drive motor (410) can be selected by using the continuously variable transmission (420), and the edge of the friction wheel (400) is provided with a rubber sleeve to reduce friction loss, thereby achieving good comprehensive benefits, and the product can meet various needs.

[0090] 10. The present invention has a simple structure and low cost, and can also realize fully automatic threading operation, saving a lot of manpower and material resources, so that the distribution inner line fully automatic threader of the present invention has a wider range of applications and greater market promotion value.

[0091] It should be noted that the technical features and beneficial technical effects that are easy to understand for those skilled in the art, are in the prior art or have been explained will not be elaborated here.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention may be modified and varied in various ways. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
