[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 A power line fastening adjustment mechanism includes a concave support plate 1, which is fixed to an external mechanism. A rectangular plate 2 is fixedly connected to the bottom of the concave support plate 1. Two symmetrically arranged fixed wheels 3 are fixedly connected to one side of the rectangular plate 2. Two movable wheels 4 that can move towards each other are provided on the concave support plate 1. The movable wheels 4 and the fixed wheels 3 are located on the same plane, so that the power line passing through the movable wheels 4 and the fixed wheels 3 will not be spatially misaligned. The two movable wheels 4 are used to spread the power line and achieve fastening of the power line.

[0025] The two ends of the power line are fixed to external equipment, and the loose parts on it can be pulled upwards and passed between the two fixed wheels 3.

[0026] like Figure 1 and Figure 2 The bottom of each of the two fixed wheels 3 is provided with a first positioning shaft 5 that can move up and down. The first positioning shaft 5 is used to prevent the power line from detaching from the fixed wheel 3. The two movable wheels 4 are each provided with a second positioning shaft 6 that can move horizontally on the side that is far away from each other. The second positioning shaft 6 is used to prevent the power line from detaching from the movable wheel 4.

[0027] The surfaces of the first positioning shaft 5, the second positioning shaft 6, the fixed wheel 3, and the movable wheel 4 are all curved, so they will not damage the power lines when they come into contact with them.

[0028] like Figure 1 and Figure 3One end of the concave support plate 1 is rotatably connected to a forward screw 7, and one end of the forward screw 7 is fixedly connected to a reverse screw 8. The connection point of the forward screw 7 and the reverse screw 8 is located at the center of one side of the concave support plate 1. One end of the reverse screw 8 passes through the concave support plate 1 and is fixedly connected to a control handle 9. The surface of the control handle 9 has anti-slip texture, which makes it convenient to manually rotate the control handle 9 to drive the forward screw 7 and the reverse screw 8 to rotate.

[0029] like Figure 1 and Figure 3 Both the forward screw 7 and the reverse screw 8 are threaded with movable blocks 10. The threads of the forward screw 7 and the reverse screw 8 are in opposite directions, so that when the forward screw 7 and the reverse screw 8 rotate, they can drive the two movable blocks 10 to move closer or further apart. A connecting rod 11 is fixedly connected to one side of the movable block 10. One end of the connecting rod 11 is fixedly connected to the movable wheel 4, which is used to drive the movable wheel 4 to move together.

[0030] like Figure 1 and Figure 3 A limiting groove 101 is provided on the concave support plate 1. A limiting block 12 is fixedly connected to one side of the movable block 10. The limiting block 12 and the limiting groove 101 are slidably connected, which can ensure that the limiting block 12 and the movable block 10 fixed to the limiting block 12 can only move in the horizontal direction.

[0031] like Figure 3 and Figure 4 A T-shaped plate 13 is fixedly connected to one side of the connecting rod 11. A connecting block 14 is slidably connected to the T-shaped plate 13. One side of the connecting block 14 is fixedly connected to the second positioning shaft 6, so that when the movable wheel 4 moves, the connecting rod 11 can drive the connecting block 14 and the second positioning shaft 6 to move together. A tension spring 20 is fixedly connected between one end of the T-shaped plate 13 and the connecting rod 11. The tension spring 20 has a pushing force on the connecting block 14 in the direction of the connecting rod 11, so that the second positioning shaft 6 can be tightly attached to the surface of the movable wheel 4.

[0032] like Figure 3 and Figure 4 A groove is provided at the bottom of the rectangular plate 2, and a tension spring 15 is fixedly connected in the groove. A drive block 16 is fixedly connected to the bottom of the tension spring 15. The tension spring 15 exerts an upward pulling force on the drive block 16. A three-end connecting shaft 17 is fixedly connected to one side of the drive block 16. Two ends of the three-end connecting shaft 17 are respectively fixedly connected to two first positioning shafts 5, so that the tension spring 15 can pull the drive block 16 and the three-end connecting shaft 17 upward, so that the first positioning shaft 5 can abut against the top of the fixed wheel 3.

[0033] The working principle of the power line tightness adjustment mechanism provided by this utility model is as follows:

[0034] When tightening the power line, pull down the three-end connecting shaft 17 to move the first positioning shaft 5 downward and separate it from the fixed wheel 3. Pass the loose part of the line between the two fixed wheels 3, and then pull it to both sides to move the loose line to both sides. Then pull the second positioning shaft 6 away from the movable wheel 4 to put the power line onto the two movable wheels 4 (e.g., Figure 1 Then release the first positioning shaft 5 and the second positioning shaft 6;

[0035] At this time, the control handle 9 can be rotated clockwise to drive the forward screw 7 and the reverse screw 8 to rotate clockwise, so that the two movable blocks 10 drive the two movable wheels 4 to move in a direction away from each other, thus tightening the power line. The tightness of the power line can be adjusted by moving the two movable wheels 4 to different distances.

[0036] Conversely, turning the control handle 9 counterclockwise causes the forward screw 7 and the reverse screw 8 to rotate counterclockwise, which in turn causes the two movable blocks 10 to move the two movable wheels 4 toward each other, thus releasing the power line.

[0037] Compared with related technologies, the power line tightness adjustment mechanism provided by this utility model has the following beneficial effects:

[0038] This invention adjusts the tightness of power lines by moving two movable wheels 4. The simultaneous movement of the two movable wheels 4 can tighten longer, loose power lines. At the same time, the movement direction of the two movable wheels 4 is consistent with the laying direction of the power lines, so it is not necessary to move the wheel set perpendicular to the laying direction of the power lines to tighten the power lines. This makes it convenient to adjust the tightness of power lines in confined spaces such as underground pipe networks.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
