Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of connection devices, specifically, it relates to a connection device between a charging pile and a transformer. Background Technology
[0002] The connection between the transformer and the charging pile typically uses high-voltage cables or a shared busbar for power transmission. For example, in a high-voltage power distribution system, the three-phase four-wire power output from the transformer (yellow, green, red, and blue wires) is connected to the charging pile distribution box via cables, and then the distribution box distributes power to each charging pile. Appropriate cable specifications must be selected based on the charging pile power, line distance, and voltage level. For example, 3×50mm² copper core cables are commonly used for the low-voltage incoming line of high-power charging piles. When connecting cables between the charging pile and the transformer, cable management is difficult to control, easily leading to tangled and messy cables. Cables are often buried in the ground, making line maintenance inconvenient and hindering temporary charging pile connections.
[0003] In view of this, this utility model is proposed. Utility Model Content

The support guide rod 12 has a hollow structure, and a telescopic guide rod 13 is slidably connected inside the hollow structure of the support guide rod 12. A mounting frame 14 is provided at the other end of the telescopic guide rod 13. 4. A guide wheel 15 is installed in the inner rotating connection. The telescopic guide rod 13 is provided with a limit fitting end 25 at one end located in the hollow of the support guide rod 12. A telescopic spring 24 is provided between the limit fitting end 25 and the end of the hollow structure. Two sets of guide wheels 15 and their matching components are symmetrically arranged. A lower mounting seat 7 is installed at the bottom of the frame body 1. The lower mounting seat 7 is connected to the support leg 8. A wheel mounting seat 9 is installed at the lower end of the support leg 8. A movable wheel 10 is installed on the wheel mounting seat 9. The movable wheel 10 is rotatably connected to the wheel mounting seat 9.
[0020] The support leg 8 has an arc-shaped structure at one end connected to the lower mounting base 7. The support leg 8 and the lower mounting base 7 are rotatably connected by a rotating shaft. Four support and storage mating holes 23 are evenly distributed on the support leg 8 along the circumferential direction on the outer side of the rotating shaft. The support and storage mating holes 23 are used to lock the support leg 8 in its support or storage state.
[0021] The lower mounting base 7 has two locking holes along the vertical direction. The position and specifications of the locking holes are compatible with the support and storage holes 23. The support and storage holes 23 are equipped with locking screws. The moving wheel 10 and its supporting components are provided with four sets.
[0022] The upper end of the support base 2 is provided with a top cover 4, which is connected to the support base 2 by screws. Both ends of the storage box 5 are provided with a box door 6 with a two-end opening structure, which facilitates the retrieval and placement of tools and accessories.
[0023] The storage box 5 is provided with a handrail mounting base 16 on the outside. The upper part of the handrail mounting base 16 is an arc-shaped structure. The handrail mounting base 16 is provided with multiple angle adjustment holes 21. An angle locking screw 22 is provided in the angle adjustment hole 21. The handrail support rod 17 is installed in the handrail mounting base 16 to lock the relative position of the handrail support rod 17.
[0024] A handrail 18 is slidably connected to the upper end of the handrail support rod 17. A lifting adjustment hole 19 is provided on the outer side of the handrail 18.

When laying cables, an auxiliary cable protection seat is provided. The cables are placed in the cable groove 28. The bottom of the cable protection seat 26 is equipped with a base plate 27, which is fixedly connected to the cable protection seat 26 with screws to facilitate cable laying. The inner wall of the cable groove 28 is provided with an inner support rib 29, which can effectively improve the structural strength of the cable protection seat 26 and effectively protect the cables in the cable groove 28. The cable protection seat 26 has corresponding fixing holes on both sides. The fixing holes are countersunk holes to facilitate the fixed installation of the cable protection seat 26. The cable laying device and the cable protection seat 26 can effectively improve the convenience and stability of the connection between the charging pile and the transformer. The support base 2 of this utility model is provided with a limiting snap-fit assembly on its side, including a support frame 11, a support guide rod 12, a telescopic guide rod 13, a mounting frame 14, and guide wheels 15. The two guide wheels 15 effectively clamp and limit the cable, avoiding the problem of the cable not being effectively limited and the cable becoming messy and tangled. The support legs 8 and handrails of the frame body 1 are all designed to be retractable, which can effectively save transportation and storage space. When laying connecting cables, a cable laying protection seat 26 is provided. The cable laying protection seat 26 is provided with a cable passage groove 28. The base plate 27 is a detachable structure, which facilitates the laying of cables and the maintenance and repair of cables. The two sides are sloped transition structures to facilitate passage.
