Detailed Implementation

[0019] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0020] Example:

[0021] like Figure 1 , 2 As shown, a cable bending test device includes a rocker arm 8 and a base 9. The rocker arm 8 is rotatably connected to a rotating seat 4. The rotating seat 4 is connected to the base 9 through a support tube 7. A screw 11 is provided on the rocker arm 8. The rocker arm 8 is connected to a first clamp 12 through the screw 11. The bottom of the first clamp 12 is connected to a second clamp 13.

[0022] A first screw 14 is provided on the first chuck 12. The other end of the first screw 14 passes through the mounting holes on the first chuck 12 and the second chuck 13 and is threadedly connected to the first nut 15, so that the first chuck 12 and the second chuck 13 are connected and fastened.

[0023] The first clamp 12 and the second clamp 13 are respectively provided with placement grooves. The placement grooves are arc-shaped and can be used to fix the cable. After the cable passes through the through hole formed by the two placement grooves, the cable can be fixed with an annular fastener with a diameter larger than the through hole to prevent the cable from coming out of the through hole. The annular fastener can be connected and fastened to the first clamp 12 and the second clamp 13 by screws. The first clamp 12 and the second clamp 13 form a clamp.

[0024] The rocker arm 8 is provided with a sliding groove 81. The upper part of the screw 11 passes through the sliding groove 81 and is threadedly connected to the second nut 10, so that the screw 11 is connected and fastened to the rocker arm 8. The screw 11 can be set at different positions along the length of the sliding groove 81 to adjust the position of the clamp and adapt to different test requirements.

[0025] The top of the rotating seat 4 is provided with a connecting rod 20. The upper part of the connecting rod 20 is threaded and the upper part of the connecting rod 20 is threadedly connected to the third nut 3. The connecting rod 20 passes through the rocker arm 8. The section of the connecting rod 20 connected to the rocker arm 8 is unthreaded, so that the rocker arm 8 can rotate around the connecting rod 20.

[0026] The bottom of the rotating seat 4 is provided with a limiting plate 6, which is connected to the support tube 7. A first bolt 5 is provided on the limiting plate 6. The first bolt 5 passes through the support tube 7 and is threaded to the base 9. The limiting plate 6 extends horizontally and can be used to restrict the upward movement of the cable. The support tube 7 can be a plastic tube with a smooth surface to avoid scratching the cable.

[0027] A handle 1 is provided on the rocker arm 8. The bottom rod 101 of the handle 1 passes through the rocker arm 8 and is threadedly connected to the fourth nut 2, so that the handle 1 is securely connected to the rocker arm 8. This arrangement facilitates the disassembly and assembly of the handle 1.

[0028] A connector 18 is provided on the base 9. The connector 18 is connected and fastened to the base 9 by a third screw 19. The connector 18 can be connected to a rope to fix the cable.

[0029] The base 9 is provided with second screws 16 at its four corners, which can be used to fix the test device on the workbench.

[0030] The second nut 10, screw 11, first chuck 12, second chuck 13, first screw 14, and first nut 15 together form a torque.

[0031] Working principle:

[0032] In use, one end of the cable to be tested is fixed to the clamp of the rocker arm 8 using a fastener, and the other end of the cable is fixed to the base 9 using a rope connected by the connector 18. By gripping the handle 1, the rocker arm 8 is rotated, causing the cable to bend repeatedly at the support tube 7. The rocker arm 8 can be rotated in conjunction with a torque adjustment device to test the bending performance of the cable under different conditions. When the torque position needs to be adjusted, the second nut 10 is removed, and the torque is adjusted by sliding the screw 11. After adjustment, the second nut 10 is tightened again, and the bending test is carried out again. After the test is completed, the bending resistance of the cable is evaluated by observing or measuring the deformation, damage, or changes in conductivity.
