Description

Technical Field

[0001] The present invention relates to the technical field of cable trays, and particularly relates to an adjustable cable tray for a charging station. Background Art

[0002] Cable trays are divided into structures such as trough type, tray type, ladder type, grid type, etc., and are composed of brackets, cantilever arms and installation accessories. The cable trays in buildings can be erected independently or laid on various building (structure) buildings and pipe gallery brackets. They have the characteristics of simple structure, flexible configuration and convenient maintenance. All parts need to be galvanized and then installed on the outdoor cable trays of buildings. Now, with the increasing number of new energy electric vehicles, charging stations are in urgent need of construction. When building a charging station, electric vehicles of various models can be charged according to different voltage levels. The cables inside the existing cable trays are directly placed in the cable trays, and the cables are arranged in a mess, lacking cable layout and fixing structures. During maintenance, it is necessary to rummage through the messy cables to find the corresponding cables, which is not convenient for maintenance.

[0003] For example, in the patent with the authorization announcement number CN212366687U, the authorization announcement date is January 15, 2021, and the name is "Cable Tray and Charging Pile". The patent includes a cable tray assembly. The cable tray assembly includes a cable bottom shell, a cover plate and cable layout parts. The cover plate is fixedly connected to the upper side of the cable bottom shell, and the cable layout parts are arranged in several rows, with several in each row. Insert the cable into the U-shaped clamping plate, rotate the screw member, and through the principle of screw drive, both ends of the screw member drive two connecting plates to approach each other respectively. The connecting plates drive the two sides of the U-shaped clamping plate to approach each other, and the two sides of the U-shaped clamping plate clamp the cable tightly to achieve the purpose of fixing and installing the cable. Each row of U-shaped clamping plates can fix multiple cables, and several rows of U-shaped clamping plates can arrange multiple groups of cables, thereby effectively improving the problem that the existing cable trays lack cable layout and fixing structures, making the cable layout neat and orderly, and facilitating the maintenance personnel to rummage through the corresponding cables.

[0004] Although there is a structure in the existing cable trays that clamps and fixes the cables through the cable layout parts, after the cable layout parts in the existing technology close and clamp the cables, the clamping force on the cables in the middle is small, so that the cables in the middle are prone to displacement during use; in addition, it is difficult for the cable layout parts in the existing technology to lock and fix cables with different diameters at the same time, unless the cables are arranged strictly according to the diameter size, which will undoubtedly greatly prolong the construction time.

[0039] As Figures 1-10 shown, a cable bridge for a charging station that is convenient for adjustment provided by an embodiment of the present invention includes a bridge assembly 1, and the bridge assembly 1 includes:

[0040] Placement bin 2, the placement bin 2 includes a bottom shell 20, an upper shell 21 is provided at the upper end of the bottom shell 20 in a snap - fit manner, the upper shell 21 and the bottom shell 20 are connected by a locking bolt 22, the upper shell 21 can seal the upper end of the bottom shell 20, a cover plate 23 is provided at the upper end of the upper shell 21 in a snap - fit manner, the cover plate 23 is used to seal the upper end of the upper shell 21, and accommodating spaces are provided inside both the bottom shell 20 and the upper shell 21 for placing cables;

[0041] Arrangement component 3, the arrangement component 3 is arranged in the accommodating space of the bottom shell 20, the arrangement component 3 includes a plurality of clamping plates 30, and the plurality of clamping plates 30 are evenly arranged along the length direction of the bottom shell 20. At least one pressing rod 31 is arranged directly above each clamping plate 30, and the pressing rod 31 and the clamping plate 30 are used to press and limit the cables;

[0042] Limiting component 4, the limiting component 4 includes a limiting mechanism 40 and a separating mechanism 41. The limiting mechanism 40 is arranged in the accommodating space of the upper shell 21, and the limiting mechanism 40 is arranged at one end of the upper shell 21. The limiting mechanism 40 is used to guide and limit the cables. A plurality of T - shaped chutes 42 are evenly arranged along the length direction in the accommodating space of the upper shell 21, and a plurality of separating mechanisms 41 are arranged along the length direction in the T - shaped chutes 42. The separating mechanism 41 is used to separate the cables.

[0043] In another embodiment provided by the present invention, a plurality of limiting columns 200 are symmetrically arranged on both sides of the upper end of the bottom shell 20, and a same number of limiting holes are correspondingly arranged at the lower end of the upper shell 21. The limiting columns 200 can be slidably arranged in the limiting holes;

[0044] The specific implementation method is as follows: When the upper shell 21 is placed on the upper end of the bottom shell 20, the limiting columns 200 are snap - fitted in the limiting holes, so that the limiting columns 200 and the limiting holes can limit the positions between the bottom shell 20 and the upper shell 21, facilitating the limiting installation between the bottom shell 20 and the upper shell 21 and avoiding the situation that the bottom shell 20 and the upper shell 21 shift during the use of the cable tray.

[0045] In another embodiment provided by the present invention, a plurality of arc - shaped grooves 300 are evenly arranged along the length direction at the upper end of the clamping plate 30. The arc - shaped grooves 300 are used to accommodate the cables, and a soft rubber layer is arranged in the arc - shaped grooves 300;

[0046] The specific implementation method is as follows: The arc - shaped grooves 300 facilitate the placement of the cables, avoiding the situation that the cables shift during the use of the cable tray because they are difficult to be fully fixed. And the soft rubber layer arranged in the arc - shaped grooves 300 can effectively reduce or even avoid the damage to the clamped and fixed cables caused by the clamping plates 30 and the pressing rods 31.

[0047] In another embodiment provided by the present invention, the abutting rod 31 includes a pressing rod 310. At both ends of the pressing rod 310, a threaded rod 311 is provided in a threaded fit manner. At one end of the threaded rod 311 away from the pressing rod 310, an abutting block 312 is provided in a rotatable manner. At one end of the abutting block 312 away from the threaded rod 311, a rubber sheet is provided. And along the length direction of the pressing rod 310, grooves 3100 are uniformly arranged on the outer side of the pressing rod 310;

[0048] The specific implementation method is as follows: The groove 3100 on the lower side of the pressing rod 310 close to the clamping plate 30 can cooperate with the arc groove 300 on the clamping plate 30 to clamp and fix the outer side of the cable, avoiding the situation that the cable is displaced when the clamping plate 30 and the pressing rod 310 clamp and fix the cable. When the abutting rod 31 presses and fixes the cable, first place the pressing rod 310 on the upper end of the cable and make the pressing rod 310 directly above the clamping plate 30, and then rotate the threaded rod 311 so that the threaded rod 311 moves along the length direction of the pressing rod 310, so that the abutting block 312 fits on the side wall of the bottom shell 20. At this time, continue to rotate the threaded rod 311 so that the threaded rod 311 locks and fixes the pressing rod 310 inside the bottom shell 20. In this way, the total length between the pressing rod 310 and the two threaded rods 311 is adjusted through the two threaded rods 311, so that the pressing rod 310 and the two threaded rods 311 are arranged in the bottom shell 20 in a supporting and fixing manner, so that the pressing rod 310 and the clamping plate 30 separate and clamp the cable between the two; In addition, place the cable above the pressing rod 310 close to the clamping plate 30, and support and fix it in the same way by another abutting rod 31 directly above the already installed and fixed abutting rod 31, so that the two pressing rods 310 press and limit the cable between the two; By analogy, multiple cables arranged in the bottom shell 20 are separated and fixed by multiple abutting rods 31, avoiding the situation that the cables inside the cable bridge are displaced during use.

[0049] In another embodiment provided by the present invention, the limiting mechanism 40 includes a vertical rod 400. Along one side of the vertical rod 400, a plurality of limiting rods 401 are uniformly arranged along the length direction. At both ends of the limiting rod 401, limiting blocks 402 are symmetrically arranged. At both ends of the limiting rod 401, they are respectively arranged in a sliding manner in the side walls of the vertical rod 400 and the upper shell 21 through the limiting blocks 402. At one end of the limiting rod 401 close to the vertical plate, an adjusting bolt 403 is provided in a threaded fit manner. The adjusting bolt 403 is used to adjust the position of the limiting rod 401 on the vertical rod 400. Along the length direction of the vertical rod 400, a plurality of spacer rods 404 are uniformly arranged. The lower ends of the spacer rods 404 are connected by a connecting plate 405. The connecting plate 405 is arranged at the bottom of the upper shell 21. The limiting rod 401 and the spacer rod 404 form a plurality of limiting spaces 406. The limiting spaces 406 are used to limit the cables;

[0050] The specific implementation manner is as follows: The cable that needs to be stably fixed passes through the limiting space 406, that is, the cable that needs to be stably fixed passes through between the limiting rod 401 and the spacer rod 404. After the cable is placed, by rotating the adjusting bolt 403, the locking and fixing of the limiting rod 401 by the adjusting bolt 403 is released, so as to adjust the movement of the limiting rod 401 on the vertical rod 400, so that the adjusting rod drives to move and approach the cable, thereby enabling the limiting rod 401 to press and fix the cable in the limiting space 406. After the position adjustment of the limiting rod 401 is completed, the adjusting screw is rotated in the reverse direction, so that the adjusting screw locks and fixes the position of the limiting rod 401 on the vertical rod 400; and when the limiting rod 401 moves along the vertical rod 400, the limiting blocks 402 at both ends of the limiting rod 401 respectively limit and guide the sliding of the limiting rod 401 in the vertical rod 400 and the upper shell 21, avoiding the situation of deviation when the limiting rod 401 moves, and the spacer plate plays a role in guiding and limiting the limiting rod 401.

[0051] In another embodiment provided by the present invention, two arc-shaped plates 407 are arranged in the limiting space 406. The arc-shaped plates 407 are arranged on the limiting rod 401. The outer sides of the arc-shaped plates 407 are connected to the limiting rod 401 through two compression springs 408, and the arc-shaped plate 407 close to the bottom of the upper shell 21 and the compression spring 408 are arranged on the connecting plate 405;

[0052] The specific implementation method is as follows: When adjusting the position of the limit rod 401 on the vertical rod 400 by the adjusting bolt 403, first pass the cable to be fixed through the limit space 406 formed by the limit rod 401 and the spacer rod 404. Then, drive the arc-shaped plates 407 to approach each other through the limit rod 401, so that the two arc-shaped plates 407 in the limit space 406 are driven by the limit rod 401 to approach each other and clamp and fix the cable therein. When the cable to be fixed is clamped and fixed by the arc-shaped plates 407, due to different usage conditions of the cable, such as fast charging and slow charging of charging piles, the diameters of the cables used are also different. At this time, first arrange the cables with the same diameter in the limit spaces 406 at the same horizontal position, so that when adjusting the position of the limit rod 401, the arc-shaped plates 407 can clamp and fix the cables with the same or similar diameters. In addition, there will be cases where cables with different diameters are placed in the limit spaces 406 at the same horizontal position. At this time, to ensure that the cable with the smallest diameter can be clamped and fixed by the arc-shaped plates 407, when adjusting the distance between the limit rods 401 to ensure that the arc-shaped plates 407 clamp the outer side of the cable, the arc-shaped plates 407 can deform themselves, and the outer side of the arc-shaped plates 407 is pressed by the compression spring 408, so that the side of the arc-shaped plate 407 can fit more closely to the outer side of the cable. In this way, when it is ensured that the limit rod 401 drives the arc-shaped plates 407 to clamp and fix the cable with a large diameter and ensure that it does not deform, the compression spring 408 presses the arc-shaped plates 407 so that the side plates of the arc-shaped plates 407 wrap and clamp the cable with a diameter smaller than that of other cables, so that the limit rod 401 can clamp and fix the cables with different diameters in the limit spaces 406 at the same horizontal position, improving the applicability of the device.

[0053] In another embodiment provided by the present invention, the limit mechanism 40 further includes a hole plate 409. The two ends of the hole plate 409 are respectively arranged on the other side of the vertical rod 400 and one side of the inner wall of the upper shell 21 in a sliding manner. A plurality of through holes 4090 are uniformly arranged on the hole plate 409;

[0054] The specific implementation method is as follows: A soft rubber layer is arranged inside the through hole 4090. The cable passes through the through hole 4090, so that the through hole 4090 separates and limits the outer side of the cable passing through it. The soft rubber layer inside the through hole 4090 can effectively prevent the edge of the through hole 4090 from scratching the outer side of the cable when the cable passes through the through hole 4090.

[0055] In another embodiment provided by the present invention, the separating mechanism 41 includes a mounting block 410. A first convex block 411 is provided at the upper end of the mounting block 410. Two locking blocks 412 are symmetrically arranged inside the mounting block 410 in a sliding manner. Two connecting springs 413 are provided at the ends of the two locking blocks 412 close to each other. The ends of the two locking blocks 412 close to each other are provided with inclined surfaces. A round rod 414 is arranged in the mounting block 410 in a sliding manner. An extrusion block 415 is arranged at the lower end of the round rod 414 in a rotating manner. Two inclined surfaces are provided on the side of the extrusion block 415. The extrusion block 415 is respectively in contact with the inclined surfaces on the two locking blocks 412 through the two inclined surfaces. A rotating block 416 is arranged at the upper end of the round rod 414 in a rotating manner. A second convex block 417 that cooperates with the first convex block 411 is provided at the lower end of the rotating block 416. The first convex block 411 and the second convex block 417 are in concave-convex cooperation. A return spring 418 is sleeved on the outer side of the round rod 414. The connecting spring 413 is arranged inside the mounting block 410;

[0056] The specific implementation method is as follows: When the cable in the limiting upper shell 21 is separated by the separating mechanism 41, first, the cables are respectively guided and limited through the limiting space 406 or the hole plate 409 of the limiting mechanism 40. After the cables pass through the limiting mechanism 40, they are inside the upper shell 21. At this time, the cables to be separated inside the upper shell 21 are stacked in the vertical direction. Then, the mounting block 410 is inserted into the T-shaped chute 42 and the mounting block 410 is made as close as possible to the stacked cables. After the mounting block 410 is inserted into the T-shaped chute 42, by rotating the rotating block 416, the second convex block 417 at the lower end of the rotating block 416 slides on the surface of the first convex block 411 on the mounting block 410. In this way, when the rotating block 416 rotates, the rotating block 416 gradually moves upward along the surface of the first convex block 411, and when the rotating block 416 moves upward, it can pull the round rod 414, so that the round rod 414 drives the extrusion block 415 to move upward along the mounting block 410. When the extrusion block 415 moves upward along the mounting block 410, the extrusion block 415 squeezes the inclined surfaces of the two locking blocks 412 that are in contact with it through the two provided inclined surfaces, so that the two locking blocks 412 squeezed by the extrusion block 415 pull the two connecting springs 413 arranged between the two locking blocks 412 to move outward of the mounting block 410. And when the lower end of the second convex block 417 at the lower end of the rotating block 416 is opposite to the upper end of the first convex block 411 at the upper end of the mounting block 410, the two locking blocks 412 can lock and fix the mounting block 410 in the T-shaped chute 42. After the mounting block 410 is locked and fixed in the T-shaped chute 42, it can separate and limit the stacked cables inside the upper shell 21; and when the rotating block 416 drives the extrusion block 415 to move upward to squeeze the extrusion block 415, the extrusion block 415 can drive the return spring 418 to compress. At this time, the return spring 418 is used to pull the rotating block 416 to ensure that the second convex block 417 at the lower end of the rotating block 416 always fits on the surface of the first convex block 411 at the lower end of the mounting block 410; in addition, when repairing the cables inside the upper shell 21, rotate the rotating block 416 again so that the lower end of the second convex block 417 at the lower end of the rotating block 416 is separated from the upper end of the first convex block 411 on the mounting block 410. At this time, the return spring 418 squeezes the extrusion block 415, so that the return spring 418 drives the extrusion block 415 to move downward along the mounting block 410 to reset. At the same time, the connecting spring 413 can pull the two locking blocks 412 to move inward of the mounting block 410, so that the locking blocks 412 release the locking and fixing of the mounting block 410, so as to remove the mounting block 410 from the T-shaped chute 42 of the upper shell 21, which is convenient for overhauling the stacked cables.

[0057] In another embodiment provided by the present invention, clamping rods 4110 are symmetrically arranged at the upper end of the first bump 411 in a sliding manner. A clamping spring 4111 is arranged between the clamping rods 4110 and the first bump 411. A clamping hole is arranged at the lower end of the second bump 417. The upper end of the clamping rod 4110 is spherical, and the upper end of the clamping rod 4110 can be arranged in the clamping hole in a sliding manner;

[0058] The specific implementation method is as follows: Rotate the rotating block 416, so that the second bump 417 at the lower end of the rotating block 416 rotates along the first bump 411 on the mounting block 410, so that the rotating block 416 drives the extrusion block 415 to extrude the connecting spring 413 to move upward along the mounting block 410 under the action of the first bump 411 and the second bump 417, so that the rotating block 416 locks and fixes the mounting block 410 in the T-shaped chute 42 through the locking block 412. When the mounting block 410 is installed and fixed, that is, when the second bump 417 moves along the first bump 411, the clamping spring 4111 can squeeze the clamping rod 4110, so that the clamping rod 4110 has a tendency to move towards the second bump 417. When the upper end of the first bump 411 faces the lower end of the second bump 417, the clamping hole provided at the lower end of the second bump 417 moves to the upper end of the clamping rod 4110. At this time, the clamping spring 4111 squeezes the clamping rod 4110, so that the upper end of the clamping rod 4110 is clamped into the clamping hole, so that the clamping rod 4110 locks and fixes the rotating block 416 and the mounting block 410 in the T-shaped chute 42 through the first bump 411 and the second bump 417. The cooperation between the clamping rod 4110 and the clamping hole reduces or even avoids the relative movement between the rotating block 416 and the mounting block 410, ensures that the mounting block 410 is firmly fixed, and is convenient for the separating mechanism 41 to separate and limit the cables in the upper shell 21.

[0059] In another embodiment provided by the present invention, a mounting hole is arranged at the upper end of the rotating block 416, and a separating rod 4160 is arranged in the mounting hole;

[0060] The specific implementation method is as follows: The separating rod 4160 is arranged in the mounting hole of the rotating block 416. In this way, the separating rod 4160 can move in the T-shaped chute 42 along with the mounting block 410, so that the separating rod 4160 can adjust the interval between it and the side wall of the upper shell 21 and between the separating rods 4160, so that the separating plate can separate and limit the cables placed in the accommodating space of the upper shell 21, ensuring the safety of each cable.

[0061] Working principle: After the bottom case 20 is installed, when placing the cable in the bottom case 20, place the cable in the arc-shaped groove 300 of the clamping plate 30. The arc-shaped groove 300 facilitates the placement of the cable, avoiding the situation where the cable shifts during the use of the cable tray due to difficulty in being fully fixed. Moreover, the soft rubber layer provided in the arc-shaped groove 300 can effectively reduce or even avoid the damage to the clamped and fixed cable caused by the clamping plate 30 and the pressing rod 31. And the lower groove 3100 of the pressing rod 310 near the clamping plate 30 can cooperate with the arc-shaped groove 300 on the clamping plate 30 to clamp and fix the outer side of the cable, avoiding the situation where the cable shifts when the clamping plate 30 and the pressing rod 310 clamp and fix the cable. When the pressing rod 31 presses and fixes the cable, first place the pressing rod 310 on the upper end of the cable and make the pressing rod 310 directly above the clamping plate 30, and then rotate the threaded rod 311 so that the threaded rod 311 moves along the length direction of the pressing rod 310, so that the abutting block 312 fits against the side wall of the bottom case 20. At this time, continue to rotate the threaded rod 311 so that the threaded rod 311 locks and fixes the pressing rod 310 inside the bottom case 20. In this way, the total length between the pressing rod 310 and the two threaded rods 311 is adjusted through the two threaded rods 311, so that the pressing rod 310 and the two threaded rods 311 are arranged in the bottom case 20 in a supporting and fixing manner, so that the pressing rod 310 and the clamping plate 30 separate and clamp the cable between them. In addition, place the cable above the pressing rod 310 near the clamping plate 30, and support and fix it directly above the already installed and fixed pressing rod 31 in the same way, so that the two pressing rods 310 press and limit the cable between them. And so on, multiple pressing rods 31 are used to separate and fix multiple cables arranged in the bottom case 20, avoiding the situation where the cables in the cable tray shift during use;

[0062] After the cables inside the bottom shell 20 are placed, the upper shell 21 is snap-fitted onto the upper end of the bottom shell 20, and the two are connected and fixed by a locking bolt 22. When the upper shell 21 is placed on the upper end of the bottom shell 20, it is snap-fitted into the limit hole through the limit post 200, so that the limit post 200 and the limit hole limit the positions between the bottom shell 20 and the upper shell 21, facilitating the limit installation between the bottom shell 20 and the upper shell 21 and avoiding the situation of displacement between the bottom shell 20 and the upper shell 21 during the use of the cable tray; after the bottom shell 20 is installed, cables are placed inside the bottom shell 20. The cables that need to be stably fixed pass through the limit space 406, that is, the cables that need to be stably fixed pass through between the limit rod 401 and the spacer rod 404. After the cables are placed, by rotating the adjusting bolt 403, the locking and fixing of the limit rod 401 by the adjusting bolt 403 is released, so as to adjust the movement of the limit rod 401 on the vertical rod 400, making the adjusting rod drive to move and approach the cable, so that the limit rod 401 presses and fixes the cable inside the limit space 406. After the position adjustment of the limit rod 401 is completed, the adjusting screw is rotated in the reverse direction, so that the adjusting screw locks and fixes the position of the limit rod 401 on the vertical rod 400; when the limit rod 401 moves along the vertical rod 400, the limit blocks 402 at both ends of the limit rod 401 respectively limit and guide the sliding of the limit rod 401 in the vertical rod 400 and the upper shell 21, avoiding the situation of deviation when the limit rod 401 moves, and the spacer plate plays a role of guiding and limiting the limit rod 401; when the adjusting bolt 403 adjusts the position of the limit rod 401 on the vertical rod 400, first pass the cable to be fixed through the limit space 406 surrounded by the limit rod 401 and the spacer rod 404, and then drive the arc plates 407 to approach each other through the limit rod 401, so that the two arc plates 407 inside the limit space 406 driven by the limit rod 401 approach each other and clamp and fix the cable inside. When the cable to be fixed is clamped and fixed by the arc plates 407, due to different usage situations of the cables, such as fast charging and slow charging of charging piles, the diameters of the used cables are also different. At this time, first arrange the cables with the same diameter in the limit space 406 at the same horizontal position, so that when adjusting the position of the limit rod 401, the arc plates 407 can clamp and fix the cables with the same or similar diameters;In addition, cables with different diameters may be placed in the limiting space 406 at the same horizontal position. At this time, to ensure that the cable with the smallest diameter can be clamped and fixed by the arc-shaped plate 407, when adjusting the distance between the limiting rods 401 to ensure that the arc-shaped plate 407 clamps and fixes the outer side of the cable, the arc-shaped plate 407 itself can deform, and the outer side of the arc-shaped plate 407 is squeezed by the compression spring 408, so that the side of the arc-shaped plate 407 can better fit the outer side of the cable. In this way, when it is ensured that the limiting rod 401 drives the arc-shaped plate 407 to clamp and fix the cable with a large diameter and ensure that it does not deform, the compression spring 408 squeezes the arc-shaped plate 407 so that the side plate of the arc-shaped plate 407 wraps and clamps the cable with a diameter smaller than that of other cables, so that the limiting rod 401 can clamp and fix the cables with different diameters in the limiting space 406 at the same horizontal position, improving the applicability of the equipment; a soft rubber layer is provided inside the through hole 4090. The cable passes through the through hole 4090, so that the through hole 4090 separates and limits the outer side of the cable passing through it. The soft rubber layer inside the through hole 4090 can effectively prevent the edge of the through hole 4090 from scratching the outer side of the cable when the cable passes through the through hole 4090;

[0063] When the separating mechanism 41 separates the cables in the limiting upper shell 21, first, the cables are respectively guided and limited through the limiting space 406 or the hole position plate 409 of the limiting mechanism 40. After the cables pass through the limiting mechanism 40, they are inside the upper shell 21. At this time, the cables to be separated inside the upper shell 21 are stacked in the vertical direction. Then, the mounting block 410 is inserted into the T-shaped chute 42 and the mounting block 410 is made as close as possible to the stacked cables. After the mounting block 410 is inserted into the T-shaped chute 42, by rotating the rotating block 416, the second convex block 417 at the lower end of the rotating block 416 slides on the surface of the first convex block 411 on the mounting block 410. Thus, when the rotating block 416 rotates, the rotating block 416 gradually moves upward along the surface of the first convex block 411, and when the rotating block 416 moves upward, it can pull the round rod 414, so that the round rod 414 drives the extrusion block 415 to move upward along the mounting block 410. When the extrusion block 415 moves upward along the mounting block 410, the extrusion block 415 squeezes the inclined surfaces of the two locking blocks 412 that are in contact with it through the two provided inclined surfaces, so that the two locking blocks 412 squeezed by the extrusion block 415 pull the two connecting springs 413 arranged between the two locking blocks 412 to move outward of the mounting block 410. And when the lower end of the second convex block 417 at the lower end of the rotating block 416 is opposite to the upper end of the first convex block 411 at the upper end of the mounting block 410, the two locking blocks 412 can lock and fix the mounting block 410 in the T-shaped chute 42. After the mounting block 410 is locked and fixed in the T-shaped chute 42, it can separate and limit the stacked cables in the upper shell 21; and when the rotating block 416 drives the extrusion block 415 to move upward to squeeze the extrusion block 415, the extrusion block 415 can drive the return spring 418 to compress. At this time, the return spring 418 is used to pull the rotating block 416 to ensure that the second convex block 417 at the lower end of the rotating block 416 always fits on the surface of the first convex block 411 at the lower end of the mounting block 410; in addition, when repairing the cables in the upper shell 21, rotate the rotating block 416 again, so that the lower end of the second convex block 417 at the lower end of the rotating block 416 is separated from the upper end of the first convex block 411 on the mounting block 410. At this time, the return spring 418 squeezes the extrusion block 415, so that the return spring 418 drives the extrusion block 415 to move downward along the mounting block 410 to reset. At the same time, the connecting spring 413 can pull the two locking blocks 412 to move inward of the mounting block 410, so that the locking blocks 412 release the locking and fixing of the mounting block 410, so as to remove the mounting block 410 from the T-shaped chute 42 of the upper shell 21, which is convenient for overhauling the stacked cables;

[0064] Rotate the rotating block 416 so that the second convex block 417 at the lower end of the rotating block 416 rotates along the first convex block 411 on the mounting block 410, so that the rotating block 416 pulls the extrusion block 415 under the action of the first convex block 411 and the second convex block 417 to extrude the connecting spring 413 to move upward along the mounting block 410, so that the rotating block 416 locks and fixes the mounting block 410 in the T-shaped chute 42 through the locking block 412. When the mounting block 410 is installed and fixed, that is, when the second convex block 417 moves along the first convex block 411, the clamping spring 4111 can squeeze the clamping rod 4110, so that the clamping rod 4110 has a tendency to move towards the second convex block 417. When the upper end of the first convex block 411 faces the lower end of the second convex block 417, the clamping hole provided at the lower end of the second convex block 417 moves to the upper end of the clamping rod 4110. At this time, the clamping spring 4111 squeezes the clamping rod 4110, so that the upper end of the clamping rod 4110 is clamped into the clamping hole, so that the clamping rod 4110 locks and fixes the rotating block 416 and the mounting block 410 in the T-shaped chute 42 through the first convex block 411 and the second convex block 417. The cooperation between the clamping rod 4110 and the clamping hole reduces or even avoids the relative movement between the rotating block 416 and the mounting block 410, ensuring that the mounting block 410 is firmly fixed, which is convenient for the separating mechanism 41 to separate and limit the cables in the upper shell 21; the separating rod 4160 is arranged in the mounting hole of the rotating block 416, so that the separating rod 4160 can move in the T-shaped chute 42 along with the mounting block 410, so that the separating rod 4160 can adjust the interval between it and the side wall of the upper shell 21 and between the separating rods 4160, so that the separating plate can separate and limit the cables placed in the accommodating space of the upper shell 21, ensuring the safety of each cable;

[0065] After the cables in the upper shell 21 are placed, snap the cover plate 23 onto the upper end of the upper shell 21 so that the cover plate 23 seals the upper end of the upper shell 21. After all the cables are placed, connect the charging pile and the reserved cable separately.

[0066] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
