[0025] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a device for improving the low temperature resistance of a charging pile cable of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1-4 As shown, a charging pile cable low temperature resistance improvement device of the utility model comprises a box body 1, a protective layer 2 is installed inside the box body 1, a mounting plate 8 is fixedly connected to the bottom of the protective layer 2, a hydraulic rod 9 is fixedly connected to the bottom of the protective layer 2, and the hydraulic rod 9 is located on the right side of the mounting plate 8, a support plate 6 is fixedly connected to the top of the hydraulic rod 9, and a clamping mechanism is provided on the left side of the mounting plate 8;

[0027] By adjusting the hydraulic rod 9 to drive the support plate 6 to move, the cable can be clamped and fixed in cooperation with the clamping mechanism, and the cable can be stored with energy and heat-insulated in cooperation with the protective layer 2;

[0028] The clamping mechanism includes a T-shaped column 11 rotatably connected to the left side wall of the mounting plate 8, and the rear end of the T-shaped column 11 passes through the right side wall of the mounting plate 8, and a limiting groove 7 is provided on the left side wall of the support plate 6. One end of the T-shaped column 11 passes through the mounting plate 8 and is fixedly connected to the limiting column 10, and the limiting column 10 is slidably connected to the limiting groove 7. The left end of the T-shaped column 11 is rotatably connected to an upper clamping rod 12, and the upper end of the right side wall of the upper clamping rod 12 is rotatably connected to a No. 1 support column 14, and the other end of the No. 1 support column 14 is fixedly connected to the left side wall of the mounting plate 8, the front end of the T-shaped column 11 is rotatably connected to the right side wall, and the upper end of the rear side wall of the lower clamping rod 13 is rotatably connected to a No. 2 support column 15, and the other end of the No. 2 support column 15 is fixedly connected to the left side wall of the mounting plate 8;

[0029] The support plate 6 is driven to move by adjusting the hydraulic rod 9, thereby driving the limit column 10 to slide in the limit groove 7, thereby driving the T-shaped column 11 to rotate. The rotation of the T-shaped column 11 drives the upper clamping rod 12 and the lower clamping rod 13 to move, and then the cable is placed between the upper clamping rod 12 and the lower clamping rod 13, so that the upper clamping rod 12 and the lower clamping rod 13 clamp and fix the cable.

[0030] like Figure 1-4As shown, the top and bottom of the protective layer 2 are fixedly connected with a fixing plate 3, a supporting column 4 is fixedly connected between the two fixing plates 3, a sliding block 5 is slidably connected to the outer surface of the supporting column 4, and the left end of the sliding block 5 is fixedly connected to the right side wall of the supporting plate 6;

[0031] The movement of the support plate 6 can drive the slider 5 to slide on the support column 4. The slider 5 can provide support for the support plate 6, making its movement more stable.

[0032] like Figure 2 as well as Figure 4 As shown, there are two groups of clamping mechanisms, which are symmetrically arranged relative to the center of the hydraulic rod 9 and are respectively located at the front and rear ends of the left side wall of the mounting plate 8;

[0037] When the support plate 6 moves, the two sliders 5 are driven to slide on the two support pillars 4 respectively, so that the movement of the support plate 6 is more stable.

[0038] like Figure 2 as well as Figure 4 As shown, the clamping ends of the upper clamping rod 12 and the lower clamping rod 13 are both installed with insulating pads 17, and the insulating pads 17 are made of rubber. Rubber has excellent low-temperature performance, which can effectively prevent the cable from cracking and extend the service life of the wires.

[0039] like Figure 1-3 As shown, the protective layer 2 is made of perfluororubber, which has good low temperature resistance.

[0040] The working principle of the device for improving the low-temperature resistance of the charging pile cable is as follows: when in use, the support plate 6 is driven to move by adjusting the hydraulic rod 9, so that the support plate 6 drives the slider 5 to slide on the support column 4, and drives the limit column 10 to slide in the limit groove 7, thereby driving the T-shaped column 11 to rotate, and the rotation of the T-shaped column 11 drives the upper clamping rod 12 and the lower clamping rod 13 to move, and then the cable is placed between the upper clamping rod 12 and the lower clamping rod 13, so that the upper clamping rod 12 and the lower clamping rod 13 clamp and fix the cable, and cooperate with the heater 16 and the protective layer 2 in the box body 1, so as to effectively improve the low-temperature protection effect of the box body 1 on the cable, and extend the service life of the cable.
