[0030] Corresponding grooves 511 are set at the bottom of the upper mold 6 and the top of the lower mold 5. The upper and lower grooves 511 are both semicircular in shape, and become a full circle after being compressed and combined. The diameters of the multiple grooves 511 are not equal, which can be suitable for repairing cable cores of different sizes. When repairing, cable cores of different thicknesses can be placed in grooves 511 of different sizes.

[0031] The lower die 5 is fixed with two guide rods 7 , and the upper die 6 passes through the guide rods 7 and slides up and down along the guide rods 7 under the action of the cylinder 8 .

[0032] The guide rod 7 plays a role of limiting and guiding, ensuring that the upper mold 6 can accurately align with the lower mold 5 when moving up and down, and can align the upper and lower grooves 511 to form a complete circle, thereby achieving the best heat patching effect.

[0039] A roller 3 for movement is provided at the bottom of the base 2 .

[0040] The roller 3 facilitates movement, so that when the cable is not easy to drag, the repair device can be pushed to a designated location to repair the cable core.

[0041] Example 2

[0042] The difference between this embodiment and embodiment 1 is that: Figure 3-5 As shown:

[0043] The workbench 4 is provided with two slide grooves 41 , which are symmetrically arranged on both sides of the lower mold 5 , and the slide grooves 41 are slidably connected with a clamping device 9 for clamping the cable core.

[0044] The clamping device 9 is used to clamp the two ends of the damaged cable to ensure that the damaged part does not shake during the repair process, thereby improving the repair effect.

[0045] The clamping device 9 includes a telescopic rod 91 , a clamp 92 and a slide block 93 . The top of the telescopic rod 91 is fixed to the clamp 92 , the bottom of the telescopic rod 91 is fixed to the slide block 93 , and the slide block 93 is slidably connected to the slide groove 41 .

[0046] The telescopic rod 91 has damping performance, that is, it can maintain the state after adjusting the telescopic degree. Under the action of the telescopic rod 91 and the slider 93, the clamp 92 can move up and down and also move along the slide groove 41, thereby realizing the clamping function of the cable.

[0047] The clamp 92 includes a stopper 921, a spring 922, a clamp plate 923 and a clamp base 924. The stopper 921, the spring 922 and the clamp plate 923 are arranged in two groups. The two groups of stoppers 921, the spring 922 and the clamp plate 923 are correspondingly arranged at both ends of the clamp base 924. The bottom of the stopper 921 is fixed to the clamp base 924, and the two ends of the spring 922 are fixed to the stopper 921 and the clamp plate 923 respectively.

[0048] The two clamping plates 923 are pressed together by the spring 922 . After the cable is placed in the clamping plate 923 , the cable can be clamped. Furthermore, cables of different sizes can be clamped to cooperate with the groove 511 to repair cables of different sizes.

[0049] One end of the clamping plate 923 away from the spring 922 is provided with a stripe 9231 for increasing friction.

[0050] The stripes 9231 improve the clamping effect and prevent the cable from slipping after being clamped.

[0051] Working principle of this device:

[0052] First, slide the clamping device 9 to the bottom of the slide groove 41, that is, the position close to the door panel 21, and then place the two ends of the damaged cable between the two clamping plates 923 respectively. Under the action of the spring 922, the clamping plate 923 clamps the cable, and wraps a layer of cable sheath at the damaged position of the cable, that is, the area where the wire core is exposed. Then, the two clamping devices 9 are pushed synchronously, and under the action of the slider 93, they move along the slide groove 41 and stop at the groove 511 suitable for the cable. The telescopic rod 91 is retracted to put the cable into the groove 511, and the control box 1 is started. The control system of the control box 1 controls the cylinder 8 to work, and controls the upper mold 6 and the lower mold 5 to work, and starts heating. Then the cylinder 8 drives the upper mold 6 to move downward until it is pressed against the lower mold 5, and then the timer 16 starts counting. After the set time, the second indicator light 17 lights up, indicating that the hot repair is completed, and then the cylinder 8 automatically drives the upper mold 6 to reset, and the cable is manually taken out to complete the repair of the wire core.

[0053] Example 3

[0054] The difference between this embodiment and the first embodiment is that the base 2 is changed from a box structure to a frame structure, and the storage area is no longer provided, but is replaced by a hollow structure.

[0055] The weight of the base 2 is reduced, making it easier to move the repair device.

[0056] Example 4

[0057] The difference between this embodiment and embodiment 1 is that a tape holder for assisting in repairing the cable core is fixed to one end of the side of the base close to the door panel.

[0058] Before repairing the cable core, after wrapping it with the cable sheath, take two pieces of the transparent tape placed on the tape holder, and then stick them symmetrically on both sides along the cable, and then place it between the upper mold 6 and the lower mold 5 for hot patching. After the hot patching is completed, tear off the transparent tapes on both sides to remove the excess cable sheath after the cable core is repaired.

[0059] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
