[0021] This utility model relates to a cable laying guide device, such as... Figure 1-4As shown, the system includes a first base 1 and a second base 2. A first mounting rod 3 and a second mounting rod 4 are respectively provided at the same end of the first base 1 and the second base 2. The first mounting rod 3 and the second mounting rod 4 are rotatably connected close to each other, and the first base 1 and the second base 2 rotate around the point where the first mounting rod 3 and the second mounting rod 4 are rotatably connected. An arc-shaped plate 5 is provided on the side of the first base 1 near the second base 2. The inner radius of the arc-shaped plate 5 is equal to its rotation radius around the point where the first mounting rod 3 and the second mounting rod 4 are rotatably connected. Multiple fixing holes 6 are evenly spaced along the circumference of the arc-shaped plate 5. A connecting rod 7 is slidably disposed inside the second mounting rod 4. The connecting rod 7 is inserted into different fixing holes 6 to adjust the first base 1 and the second base 2. The angle between adjacent sides of the two bases 2, the bottom of the plug rod 7 extends below the fixing hole 6, and is threaded with a fixing nut 8 for fixing the first mounting rod 3 and the second mounting rod 4. Two guide rollers 9 for cable laying are rotatably installed inside the first base 1 and the second base 2 respectively. Side rollers 10 for cable laying are rotatably installed at the four bottom corners of the upper end of the first base 1 and the second base 2 respectively. The first base 1 and the second base 2 serve as the bottom support structure for both ends of the cable to ensure the stability of the cable during corner pulling. Either the first base 1 or the second base 2 can be used as the starting end. The first mounting rod 3 and the second mounting rod 4 are rotatably connected by their ends approaching each other. By rotating the first base 1 and the second base 2, the included angle between them is changed. Guide rollers 9 and side rollers 10 are installed, and the cable is pulled at the upper end of the guide rollers 9, causing them to rotate. The side rollers 10 rotate at the four bottom corners of the upper ends of the first base 1 and the second base 2, reducing the frictional resistance on the sides of the cable and thus reducing the resistance when the cable passes through the first base 1 and the second base 2. By installing an arc-shaped plate 5, a fixing hole 6, a plug-in rod 7, and a fixing nut 8, when the first base 1 is rotated, the arc-shaped plate 5 rotates. After the fixing hole 6 is inserted into the plug-in rod 7, the plug-in rod 7 is limited in the rotation direction of the arc-shaped plate 5, thus ensuring a proper distance between the first base 1 and the second base 2. The included angle is fixed by having multiple fixing holes 6 evenly spaced on the circumference of the arc plate 5, allowing different fixing holes 6 to be inserted and matched with the plug rod 7, adjusting the included angle between the first base 1 and the second base 2, thereby conveniently and accurately controlling the included angle size, and thus accurately adjusting the turning radius of the cable. The plug rod 7 is fixed in the vertical position by the threaded connection of the fixing nut 8 to the bottom of the plug rod 7, and the stability of the arc plate 5 and the second mounting rod 4 is improved. When laying the cable, the cable is inserted from one end of the first base 1 or the second base 2 away from the other base, and then out from the other end, then into the adjacent end of the other base, into the base, and then out from the other end, thus solving the problem to be solved by this utility model.

[0022] In this embodiment of the utility model, one end of the arc-shaped plate 5 is disposed on the upper end of the first mounting rod 3, and two L-shaped limiting blocks 11 are disposed at the bottom of the second mounting rod 4. The middle part of the arc-shaped plate 5 is slidably connected to the inner side of the adjacent side of the two limiting blocks 11. By setting the limiting blocks 11, the middle part of the arc-shaped plate 5 is slidably connected to the inner side of the adjacent side of the two limiting blocks 11, so as to ensure that the arc-shaped plate 5 and the second mounting rod 4 are parallel to each other, and improve the stability of the arc-shaped plate 5 when rotating.

[0023] In this embodiment of the invention, the number of fixing holes 6 is eleven, and the included angle between two adjacent fixing holes 6 is fifteen degrees. By setting eleven fixing holes 6, the included angle between the first base 1 and the second base 2 can be selected as follows: 180 degrees, 165 degrees, 150 degrees, 135 degrees, 120 degrees, 105 degrees, 90 degrees, 75 degrees, 60 degrees, 45 degrees, and 30 degrees, thereby improving the accuracy of the included angle between the first base 1 and the second base 2, and thus facilitating the accurate turning of the cable at the above-mentioned angles.

[0024] In this embodiment of the utility model, a top cover 12 is respectively provided on the upper end of the first base 1 and the second base 2. The top of the spindle of the four side rollers 10 is rotatably connected to the bottom of the top cover 12. The four bottom corners of the upper end of the first base 1 and the second base 2 are respectively rotatably connected to the bottom of the spindle of the four side rollers 10. Limiting plates 13 are respectively provided on both sides of the cable laying direction between the upper end of the first base 1 and the second base 2 and the lower end of the top cover 12. By providing the top cover 12, the spindle of the four side rollers 10 provides vertical support, thereby improving the stability of the top cover 12 and limiting the upward movement of the cable. By providing the limiting plates 13, the side of the cable is limited, ensuring that the cable is inside the first base 1 and the second base 2 and preventing the cable from shifting.

[0025] In this embodiment of the invention, the first mounting rod 3 and the second mounting rod 4 are respectively provided with mounting holes 14 at their respective ends close to each other. The two mounting holes 14 are vertically connected, and a locking screw 15 is inserted into the two mounting holes 14 vertically. The top of the locking screw 15 extends to the upper end of the upper mounting hole 14 and is threadedly connected to a locking nut 16. The outer bottom of the locking screw 15 contacts the outer bottom of the lower mounting hole 14. By providing mounting holes 14, locking screws 15, and locking nuts 16, the locking screw 15 passes through the corresponding mounting holes 14 of the first mounting rod 3 and the second mounting rod 4, and the upper end of the locking screw 15 is threadedly connected to the locking nut 16, so that the adjacent sides of the first mounting rod 3 and the second mounting rod 4 are in contact, thereby improving the structural strength.

[0026] In this embodiment of the present invention, the bottom of the first mounting rod 3, located outside the mounting hole 14, is provided with multiple slots 17 in the circumferential direction. The top of the second mounting rod 4, located outside the mounting hole 14, is provided with multiple protrusions 18 in the circumferential direction. The slots 17 and protrusions 18 correspond one-to-one, and the protrusions 18 are inserted into the slots 17. By providing the slots 17 and protrusions 18, the first mounting rod 3 and the second mounting rod 4 are in contact on adjacent sides, so that the protrusions 18 are inserted into the slots 17 one-to-one, thereby improving the circumferential stability of the first mounting rod 3 and the second mounting rod 4 at the rotational connection.

[0027] In an embodiment of this utility model, a circular groove 19 is provided on the outer side of the adjacent end of the mounting hole 14 corresponding to the first mounting rod 3 and the second mounting rod 4 in the circumferential direction. One end of four compression springs 20 is provided equidistantly in the circumferential direction inside one of the grooves 19. The other end of the four compression springs 20 is slidably connected to the inside of the other groove 19 in its circumferential direction. By setting the grooves 19 and the compression springs 20, the elastic force of the four compression springs 20 acts between the first mounting rod 3 and the second mounting rod 4, ensuring that the elastic force in the circumferential direction of the mounting hole 14 is uniform. When the locking nut 16 is not tightened on the upper end of the locking screw 15, the inside of the slot 17 and the protrusion 18 are separated from each other by the elastic force. When the locking nut 16 is tightened on the upper end of the locking screw 15, the compression spring 20 is compressed, and the inside of the slot 17 and the protrusion 18 are inserted one-to-one, thereby facilitating the high-frequency adjustment of the included angle between the first base 1 and the second base 2.

[0028] In this embodiment of the invention, the middle part of the top cover 12 corresponding to the first base 1 and the second base 2 is respectively threaded with a transmission rod 21 in the vertical direction. The bottom of the transmission rod 21 extends to the lower end of the top cover 12 and is rotatably connected to the middle part of the spindle of the two pressing wheels 22. The spindle of the two pressing wheels 22 is integral and set in the horizontal direction. The two ends of the two pressing wheels 22 that are far apart from each other are close to the limiting plate 13 on the corresponding side. By setting the transmission rod 21 and the pressing wheel 22, the transmission rod 21 rotates in the middle part of the top cover 12, driving the pressing wheel 22 to move in the vertical direction, moving downward from the upper end of the cable, pressing the cable on the guide roller 9, limiting the upper end and both sides of the cable, and improving the stability of the cable during traction.

[0029] In this embodiment of the invention, the guide roller 9 is a concave roller with a concave structure in the middle. By setting the guide roller 9 to be a concave roller with a concave structure in the middle, the guide roller 9 limits the two sides of the cable and guides the cable to be pulled in the middle of the guide roller 9, preventing the cable from shifting to the two sides of the guide roller 9.

[0030] In an embodiment of this utility model, support frames 23 are respectively provided on both sides of the bottom of the first base 1 and the second base 2 in the cable laying direction. By providing support frames 23, the stability of the bottom of the first base 1 and the second base 2 on the ground is improved when the cable is pulled inside the first base 1 and the second base 2.

[0031] In use, firstly, adjust the angle between the first base 1 and the second base 2, rotate the first base 1, and drive the arc plate 5 to rotate. After the fixing hole 6 is inserted into the plug rod 7, the plug rod 7 is limited in the rotation direction of the arc plate 5, so that the angle between the first base 1 and the second base 2 is fixed. By allowing different fixing holes 6 to be inserted into the plug rod 7, the angle between the first base 1 and the second base 2 can be adjusted. Then, the cable is inserted from one end of the first base 1 or the second base 2 away from the other base, and then out from the other end. After that, it enters the adjacent end of the other base, enters the base, and then out from the other end. The transmission rod 21 rotates in the middle of the top cover 12, driving the pressure wheel 22 to move vertically and move downward from the top end of the cable, pressing the cable onto the guide roller 9. The upper end and both sides of the cable are limited. At this time, the cable is laid according to the angle between the first base 1 and the second base 2.
