A sliding cylinder 13 is symmetrically installed on the inner side of the middle part of the sleeve body 4, and a telescopic rod 14 is connected to the inside of the sliding cylinder 13, and a rotating part 16 is connected between adjacent telescopic rods 14.

[0035] The slide rod 10 is fixedly connected to the sleeve housing 4 on the other side, the limit block 11 is located on the inner side of the step groove 9, the limit block 11 is slidably connected to the step groove 9, the end of the spring 12 away from the limit block 11 is fixedly connected to the side wall of the step groove 9, the spacer areas 7 are not less than two, the step groove 9 is circumferentially arranged, the step grooves 9 are not less than four, and the number of the slide rods 10 matches the step grooves 9.

[0036] Through the cooperation of the rubber sleeve layer 2, the spacer area 7 and the stretching cloth layer 8, when the cable body 1 is stretched, the spacing of the spacer area 7 facilitates the stretching movement between the sleeve body 4. The movement of one side of the sleeve body 4 will pull the sliding rod 10, and the sliding rod 10 drives the limit block 11 to move. The limit block 11 slides inside the step groove 9. The limit block 11 compresses or stretches the spring 12, and the spring 12 reacts to the limit block 11, thereby reducing the stretching movement of the sleeve body 4.

When bending, the bending of the cable body 1 will drive the sleeve shell 4 to bend, and the sleeve shell 4 drives the spring 2 15 and the telescopic rod 14 on one side to rotate. The two adjacent telescopic rods 14 rotate through the rotating member 16, and the telescopic rod 14 can be telescoped and slid inside the spring 2 15, so as to adapt to the contraction of the inner side and the stretching of the outer side of the bending part of the cable body 1, thereby improving the bending use of the wear-resistant layer 3 at the corner, reducing the damage of the cable body 1, and extending the service life of the cable body 1.

[0041] Working principle:

[0042] Before using this kind of wire and cable with anti-stretching structure, it is necessary to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6 As shown, when the cable body 1 is stretched, the spacing of the spacing area 7 facilitates the stretching movement between the sleeve shells 4. The movement of one side of the sleeve shell 4 will pull the sliding rod 10, and the sliding rod 10 drives the limit block 11 to move. The limit block 11 slides inside the step groove 9. The limit block 11 compresses or stretches the spring 12, and the spring 12 reacts to the limit block 11, thereby reducing the stretching movement of the sleeve shell 4. The stretching cloth layer 8 is used to limit the sleeve shell 4 to prevent the sleeve shell 4 from shaking back and forth left and right, thereby improving the tensile resistance of the cable body 1.

[0043] When used at a corner and the cable body 1 needs to be bent at an angle, the sleeve body 4 is sleeved on the outside of the wear-resistant layer 3, so that the installation sleeve 5 fits the wear-resistant layer 3, and the installation sleeve 5 is fixed by the fixing bolts 6, so that the sleeve body 4 can easily sleeve and fix the wear-resistant layer 3. When bending, the bending of the cable body 1 will drive the sleeve body 4 to bend, and the sleeve body 4 drives the spring 2 15 and the telescopic rod 14 on one side to rotate.

[0044] The two adjacent telescopic rods 14 rotate through the rotating member 16, and the telescopic rod 14 can be telescoped and slid inside the spring 2 15, so as to adapt to the inner contraction and outer stretching of the bending part of the cable body 1, improve the bending use of the corner of the wear-resistant layer 3, reduce the damage of the cable body 1, and extend the service life of the cable body 1.
