Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a wire dispersion and guiding device includes a base plate 1. A clamp 2 is fixedly installed above the center of the base plate 1, through which the wire passes. Each of the four corners of the base plate 1 is a quarter circle. Telescopic arms 3 are rotatably mounted at the four corners of the base plate 1 via pivot pins. Sub-arms 4 are slidably mounted inside the telescopic arms 3, through which the wire passes. A positioning support block 5 is fixedly installed at the bottom of the telescopic arms 3. Positioning support grooves 6 are formed at each of the four corners of the base plate 1, and the positioning support blocks 5 are located inside the positioning support grooves 6. A mounting frame 7 is arranged in a circular array around the central axis of the base plate 1 on the upper surface of the base plate 1. A first positioning guide wheel 8 is rotatably mounted on the top of the mounting frame 7 via pivot pins. One end of the sub-arm 4... The telescopic arm 3 is equipped with a second positioning guide wheel 9. Four steel wire ropes pass through the clamp 2 and then pass through the first positioning guide wheel 8 and the second positioning guide wheel 9 in sequence before passing through the sub-arm 4. The first positioning guide wheel 8 positions and guides the steel wire ropes passing through the dispersion hole 10, preventing excessive compression of the steel wire ropes into the dispersion hole 10. The second positioning guide wheel 9 positions and guides the steel wire ropes passing through the first positioning guide wheel 8 and controls the guide steel wire ropes to pass through the steel wire hole 11, preventing excessive compression of the steel wire ropes into the steel wire hole 11 and improving safety during use. By setting the positioning support blocks 5 on the telescopic arm 3 inside the positioning support grooves 6 at the four corners of the base plate 1, the position of the telescopic arm 3 can be supported, preventing damage to the shaft pin position installed on the telescopic arm 3 under external force during use, thus improving safety during use.

[0022] like Figures 1 to 4 As shown, the middle part of the clamp 2 is provided with a ring array of dispersing holes 10 with the central axis of the clamp 2 as the axis, and one end of the sub-arm 4 is provided with a wire hole 11, and the wire passes through the dispersing holes 10 and the wire hole 11.

[0023] By passing four steel wire ropes through the dispersion holes 10 of the clamp 2 and through the steel wire holes 11 on the sub-arm 4, the four steel wire ropes can be dispersed and guided.

[0024] like Figures 1 to 4 As shown, the outer middle section of the first positioning guide wheel 8 is located in the middle vertical section of the dispersion hole 10, and the outer middle section of the second positioning guide wheel 9 is located in the middle vertical section of the wire hole 11. The height difference between the bottom section of the first positioning guide wheel 8 and the top section of the second positioning guide wheel 9 is the diameter of the wire.

[0025] The steel wire rope can be controlled to pass vertically through the dispersion hole 10 and the steel wire hole 11.

[0026] like Figures 1 to 4 As shown, the bottom end of the mounting bracket 7 is rotatably mounted on the surface of the substrate 1 via a pivot pin.

[0027] When adjusting the rotation angle of the telescopic arm 3, the adjustable mounting bracket 7 rotates on the base plate 1 to adjust the direction of the wire rope passing through the first positioning guide wheel 8.

[0028] like Figures 1 to 4 As shown, a sliding hole 12 is provided at one end of the sub-arm 4, and a positioning rod 13 is slidably installed inside the sliding hole 12. A spring 14 is sleeved on the outer side of the top end of the positioning rod 13. One end of the spring 14 is fixedly connected to the top end of the positioning rod 13, and the other end of the spring 14 is fixedly connected to the upper surface of the sub-arm 4. A connecting hole 15 is provided at equal intervals at the bottom end of the telescopic arm 3. The positioning rod 13 is slidably connected to the connecting hole 15. The four corners of the base plate 1 are provided with positioning holes 16 arranged in a ring array with the center circle of the rounded corner of the base plate 1 as the axis and at equal intervals. The positioning holes 16 are slidably inserted into the positioning rod 13.

[0029] By pulling the positioning rod 13 upwards, the bottom end of the positioning rod 13 slides out of the connecting hole 15. At this time, the spring 14 is in a stretched state, controlling the sliding of the sub-arm 4 inside the telescopic arm 3 and controlling the rotation of the telescopic arm 3. Then, the positioning rod 13 is inserted into the other connecting hole 15 and positioning hole 16 to fix the size of the four steel wire ropes, which can be used for different situations.

[0030] like Figures 1 to 4 As shown, the top of the substrate 1 is fixedly mounted with connecting rods 17 in a ring array around the central axis of the substrate 1. The tops of the four connecting rods 17 are fixedly connected to the outer side of the clamp 2, and the connecting rods 17 are inclined.

[0031] The clamp 2 is connected by four connecting rods 17.

[0032] This utility model provides a wire dispersion and guiding device, the specific working principle of which is as follows:

[0033] In use, four steel wire ropes are passed through the dispersion holes 10 of the clamp 2, and then sequentially through the first positioning guide wheel 8 and the second positioning guide wheel 9 before passing through the wire hole 11 on the sub-arm 4. The position of the wire hole 11 is determined by the mating dimensions of the telescopic arm 3 and the sub-arm 4, and also by the angle of the telescopic arm 3 on the base plate 1, thereby adjusting the size and shape of the four steel wire ropes. The first positioning guide wheel 8 positions and guides the steel wire ropes passing through the dispersion holes 10, preventing excessive compression of the steel wire ropes into the dispersion holes 10. The second positioning guide wheel 9 positions and guides the steel wire ropes passing through the first positioning guide wheel 8, and controls the guide steel wire ropes as they pass through the wire hole 11, preventing excessive compression of the steel wire ropes into the wire hole 11 and improving safety during use. Meanwhile, during use, by setting the positioning support block 5 on the telescopic arm 3 inside the positioning support groove 6 at the four corners of the base plate 1, the position of the telescopic arm 3 can be supported, preventing the shaft pin position installed on the telescopic arm 3 from being damaged under external force during use, thus improving the safety of use. When adjusting the relative position between the telescopic arm 3 and the sub-arm 4, by pulling the positioning rod 13 upward, the bottom end of the positioning rod 13 slides out of the connecting hole 15. At this time, the spring 14 is in a stretched state, controlling the sub-arm 4 to slide inside the telescopic arm 3, and controlling the rotation of the telescopic arm 3. Then, the positioning rod 13 is inserted into the other connecting hole 15 and positioning hole 16 to fix the size of the four steel wire ropes, which can be used to adapt to different situations.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
