[0030] The fixing mechanism comprises a first clamping block 10, a second clamping block 11 and a cable body 12, the first clamping block 10 is fixedly arranged at the lower end of the connecting rod 5 on the surface of the shell 1, the second clamping block 11 is arranged on one side of the surface of the first clamping block 10, the cable body 12 is arranged between the first clamping block 10 and the second clamping block 11, the upper end of the cable body 12 is sleeved in the hook 7, the cable body 12 to be tested can be conveniently fixed by the fixing mechanism; and since the cable body 12 is sleeved in the hook 7, the cable body 12 can be driven to rotate together when the hook 7 rotates; thus the parts of the cable body 12 on the upper end of the first clamping block 10 can be wound together, and the cable bending and twisting fatigue strength can be detected at one time.

[0031] A locking screw 13 is arranged between the first clamping block 10 and the second clamping block 11; the first clamping block 10 and the second clamping block 11 can be conveniently fixed by the locking screw 13 to clamp the cable body 12.

[0032] The outer surface of the hook 7 is movably provided with a limiting rod 14 through a rotating shaft, and the limiting rod 14 can prevent the cable body 12 from falling off from the hook 7;

[0033] The outer surface of the movable rod 4 is movably provided with a limiting ring 15, and the outer surface of the movable rod 4 is sleeved with a reset spring 16 between the limiting ring 15 and the fixed block 3, and the reset spring 16 can conveniently push the movable rod 4, the connecting rod 5 and the hook 7 upward to reset, so as to drive the cable body 12 to rotate reversely to restore the mutually entangled cables; and the stroke of the upward reset of the movable rod 4 under the action of the spring should be greater than the length of the cable body 12 reserved on the upper end of the first clamping block 10, that is, after the cable body 12 is pulled tight, the spring still has the elasticity to push the movable rod 4 to continue to move upward, and at this time, since the lower end of the cable body 12 is clamped by the first clamping block 10 and the second clamping block 11, the function of pulling the cable body 12 is achieved, so that the pulling strength of the cable body 12 can be detected;

[0034] The upper end of the movable rod 4 is movably provided with a roller 17 through a rotating shaft, and the outer surface of the roller 17 is in close contact with the outer surface of the cam 2, so that the unnecessary friction loss can be avoided by replacing the contact between the movable rod 4 and the cam 2 with the roller 17;

[0035] The inside of the shell 1 is fixedly provided with a mounting seat 18, the inside of the mounting seat 18 is fixedly provided with a motor 19, and the output shaft end of the motor 19 is in transmission connection between the rotating shaft where the cam 2 is located through a shaft coupling; the motor 19 can drive the cam 2 to continuously rotate, so that the device can detect the mechanical strength of the cable, and the motor 19 only needs to continuously rotate in one direction during the entire detection process, without the need for stoppage and reverse rotation and other operation requirements, so that the detection speed and efficiency of the device can be greatly improved;

[0036] The lower end of the shell 1 is fixedly provided with a mounting plate 20, and the mounting plate 20 can conveniently fix and install the device as a whole at a target position.

[0037] Working principle: before using the device, the cable body 12 to be detected is clamped and fixed by the first clamping block 10 and the second clamping block 11, so that a loop appears on the upper end of the cable body 12, and the loop is sleeved inside the hook 7, so that Figure 1 The state shown in the figure can be finally formed;

[0038] Then the mechanical strength detection of the cable body 12 can be carried out, and during the detection, the motor 19 is turned on to drive the cam 2 to continuously rotate, as shown in Figure 1 At this time, the cam 2 presses Figure 1The shown perspective angle rotates clockwise; at this time, the cam 2 can be used to extrude and force the movable rod 4, the connecting rod 5, and the hook 7 to move downward; when the connecting rod 5 moves downward, the limiting ball block 9 is clamped in the spiral sliding groove 6 of the connecting rod 5, so that the connecting rod 5 that moves downward is forced to rotate under the action of the limiting ball block 9 and the spiral line of the spiral sliding groove 6 itself; thus, the hook 7 can be driven to rotate; in this way, the hook 7 can push the cable body 12 downward while winding the cable itself; then, with the rotation of the cam 2, the cam 2 no longer extrudes the movable rod 4; at this time, the movable rod 4, the connecting rod 5, and the hook 7 can move upward under the action of the spring and reset; at this time, the connecting rod 5 rotates in the opposite direction under the action of the limiting ball block 9, so that the originally wound cable can be released; thus, through the continuous rotation of the cam 2, the bending and torsional fatigue strength of the cable body 12 can be detected.

[0039] When the movable rod 4 moves upward and resets, the upward reset stroke of the movable rod 4 under the action of the spring should be greater than the length of the cable body 12 reserved at the upper end of the first clamping block 10; that is, after the cable body 12 is pulled tight, the spring still has the force to push the movable rod 4 to continue to move upward; at this time, since the lower end of the cable body 12 is clamped by the first clamping block 10 and the second clamping block 11, the cable body 12 can be pulled, so that the pulling strength of the cable body 12 can be detected.

[0040] When the device is used, the motor 19 can drive the cam 2 to rotate continuously, so that a series of detection operations can be completed, so that the cable is wound and then unwound and reset, and the cable also receives a pull during the reset; thus, the device can detect the mechanical strength of the cable, and the motor 19 only needs to continuously rotate in one direction during the entire detection process, without the need for stopping and reversing, so that the detection speed and efficiency of the device can be greatly improved.

[0041] Thus, the device has good detection effect on the cable and can be suitable for high-standard cable quality inspection requirements in the field of aviation.
