[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-5 As shown, a tensioning device for laying wires and cables includes a base plate 1, a protective frame 4 fixedly installed at the upper edge of the base plate 1, a tensioning structure 2 movably connected to the upper middle part of the base plate 1, and an anti-detachment structure 3 movably connected to the rear part of the tensioning structure 2.

[0028] The tensioning structure 2 includes a reverse double threaded rod 21. A mounting groove 22 is provided through the middle of the upper end of the base plate 1. The front end of the reverse double threaded rod 21 is rotatably connected to the front of the inner wall of the mounting groove 22. A through hole is provided through the middle of the rear part of the inner wall of the mounting groove 22. A connecting post 23 is rotatably connected to the inner wall of the through hole. The rear end of the connecting post 23 is fixedly connected to the rear end of the reverse double threaded rod 21. A drive plate 24 is threadedly connected to the front and rear parts of the outer wall of the reverse double threaded rod 21. A rotating shaft 25 is rotatably connected to the upper end of each of the two drive plates 24. The two rotating shafts 25 are staggered. A tensioning wheel 26 is fixedly sleeved on the top of the outer wall of each of the two rotating shafts 25.

[0029] The anti-detachment structure 3 includes a sliding plate 31, a movable groove 32 is provided in the middle of the rear side of the connecting column 23, the outer wall of the sliding plate 31 is movably connected to the inner wall of the movable groove 32, a fixed column 33 is rotatably connected in the middle of the inner wall of the sliding plate 31, an adsorption block 34 is fixedly installed in the front of the inner wall of the movable groove 32, and an adsorption groove 35 matching the adsorption block 34 is provided in the middle of the front side of the fixed column 33.

[0030] The tensioning structure 2 expands the tensioning range of the cable by utilizing two tensioning rollers 26 with the same stroke but opposite directions. Two guide rollers 29 and two auxiliary rollers 211 allow the wires and cables to be laid in a straight or curved path during installation, ensuring stability and accuracy and preventing cable tangling and crossing. Furthermore, the two guide rollers 29 separate the cable tensioning position (the part of the tensioning roller 26 contacting the cable) from the cable passage position (the part of the auxiliary roller 211 contacting the cable), sharing the cable guiding work and preventing external influences on the left and right sides of the cable from directly affecting the cable tensioning part, making it highly practical. The anti-detachment structure 3 allows the rotation of the reverse double threaded rod 21 to be designed as a press-type rotation drive, making the reverse double threaded rod 21 less susceptible to external influences (such as accidental contact). In use, first press the fixing post 33 forward, causing it to move the slide plate 31 close to the adsorption block 34. The adsorption block 34 will be magnetically attracted into the adsorption groove 35, thus fixing the position of the slide plate 31. Then, rotating the fixed column 33 will cause the connecting column 23 and the reverse double threaded rod 21 to rotate, so that the adjustment of the reverse double threaded rod 21 requires two actions: pressing and rotating, which improves the stability of the device tensioning.

[0031] like Figure 4 As shown, the inner wall of the mounting groove 22 is provided with sliding grooves 27 on both the left and right sides, and the left and right sides of the two drive plates 24 are slidably connected to the inner walls of the two sliding grooves 27.

[0032] The slide 27 guides the movement of the drive plate 24.

[0033] like Figure 3 As shown, the upper left and right sides of the base plate 1 are rotatably connected to the two rotating shafts 28. The two rotating shafts 28 are located on the upper diagonal of the base plate 1, and the top of the outer wall of the two rotating shafts 28 are fixedly sleeved with guide wheels 29.

[0034] Two guide wheels 29 separate the cable tensioning position (the part of tension wheel 26 that contacts the cable) and the cable passage position (the part of auxiliary wheel 211 that contacts the cable). They can share the cable guiding work and prevent the cable tensioning part from being directly affected when the left and right sides of the cable are affected by external factors.

[0035] like Figure 3 As shown, the upper left and right sides of the base plate 1 are rotatably connected to the middle of the two shafts 210, and the top of the outer wall of the two shafts 210 are fixedly sleeved with auxiliary wheels 211.

[0036] The auxiliary wheel 211 can roll and support the weight of the wires and cables, while guiding the wires and cables to be laid along a predetermined path, ensuring that the wires and cables remain straight or bend according to a specific curvature, thereby avoiding tangling and crossing of the wires and cables.

[0037] likeFigure 3 As shown, the two auxiliary wheels 211 are located on the outside of the two guide wheels 29 respectively. The outer wall of the cable extends into the front of the outer surface of the left auxiliary wheel 211 and extends out from the rear of the outer surface of the right auxiliary wheel 211.

[0038] like Figure 5 As shown, both the adsorption block 34 and the adsorption tank 35 are magnetic, and the magnetic poles of the adsorption block 34 and the adsorption tank 35 are opposite.

[0039] When the fixing post 33 approaches the adsorption block 34, the adsorption block 34 and the adsorption groove 35 will be attracted together by magnetism, thereby fixing the fixing post 33 and the slide plate 31 in this position.

[0040] like Figure 5 As shown, a reset spring 36 is fixedly installed at the front edge of the slide plate 31. The front end of the reset spring 36 is fixedly connected to the front part of the inner wall of the moving groove 32. The reset spring 36 is arranged around the fixed post 33 and the adsorption block 34.

[0041] When it is necessary to enter the anti-detachment state, the operator can move the slide plate 31 by external force. At this time, the return spring 36 will be stretched. When the force is large enough, the elastic force of the return spring 36 will support the slide plate 31 and the fixed column 33 in a position away from the adsorption block 34.

[0042] The working principle of this utility model is as follows: In use, the cable is fitted onto the surfaces of the two guide wheels 29, the two auxiliary wheels 211, and the two tensioning wheels 26 (e.g., Figure 1 and Figure 4 The cable extends from the front of the left auxiliary wheel 211, and its outer wall extends from the rear of the right auxiliary wheel 211. Pressing the fixing post 33 forward causes the sliding plate 31 to approach the adsorption block 34. The adsorption block 34 is magnetically attracted into the adsorption groove 35, thus fixing the position of the sliding plate 31. Rotating the fixing post 33 causes the connecting post 23 and the reverse double-threaded rod 21 to rotate. The two drive plates 24, threadedly connected to the reverse double-threaded rod 21, move away from each other in the two grooves 27, thereby tightening the cable with the two tensioning wheels 26. The two guide wheels 29 and the two auxiliary wheels 211 allow the wires and cables to be laid in a straight or curved path during installation, ensuring stability and accuracy. Then, pull the fixed column 33 backward, causing it to move the slide plate 31 away from the adsorption block 34. When the force is large enough, the elastic force of the return spring 36 will support the slide plate 31 and the fixed column 33 in a position away from the adsorption block 34 when the adsorption block 34 and the adsorption groove 35 are in place. This makes the adjustment of the reverse double threaded rod 21 require two actions: pressing and rotating, which improves the stability of the device tensioning.

[0043] 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 claims.
