Technical Field

[0002] Cable is a general term for optical cables, electrical cables and other items. Cables have many uses, mainly used for control installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. After the production of cables, their tensile strength needs to be tested to ensure the normal use of the cables. In industry, it is often necessary to test the bearing capacity of cables to avoid failure or accidents caused by insufficient bearing capacity of cables. The existing manual detection of the tensile strength of the cable surface has the disadvantages of low detection accuracy and poor detection effect. However, through artificial force, the force applied to the cable each time is not easy, which will affect the measurement results to a certain extent.

[0003] There are many cable detection devices in the prior art, such as a special cable tensile detection device with publication number CN220188200U, which includes a detection operation table, a tensile detection device and a cable bracket, the cable bracket includes a symmetrically arranged left fixed bracket and a right adjustable bracket, the tensile detection device is located at the center of the left fixed bracket and the right adjustable bracket, the left fixed bracket and the right adjustable bracket are both provided with a clamping assembly, the right adjustable bracket is provided with a wire entry hole at one end close to the clamping assembly, the wire entry hole is connected to the clamping assembly of the right adjustable bracket, the detection operation table is provided with a guide groove, and the right adjustable bracket is fixedly connected to the guide groove by a fixing screw. Its advantages are that the detection level is relatively accurate and the equipment cost is low, but its disadvantages are that it cannot detect whether there are cracks on the surface of the cable after curling, and the detection quality of the cable cannot be guaranteed.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0011] According to a low-temperature cable detection device of the utility model, a ratchet is provided at one end of the reciprocating screw rod close to the driving member, and a ratchet is also provided at one end of each reciprocating rod close to the driving member.

[0012] The purpose of the utility model is to provide a low-temperature cable detection device. When detecting the low-temperature cable, one end of the low-temperature cable is fixedly connected to the rotating shaft, and the other end of the low-temperature cable is fixedly connected to the clamp on the telescopic sleeve. When detecting whether the low-temperature cable is curled for cracks, the driving member rotates forward, and the output shaft of the driving member is connected to the reciprocating rod through a belt.

The reciprocating screw rotates one circle, and the auxiliary groove reciprocates once, which is convenient for stretching and retracting the cryogenic cable, and also convenient for detecting the toughness of the cryogenic cable.
