[0002] During the operation of charging piles, surge protectors must be installed to prevent damage to internal circuits and equipment caused by sudden surges such as lightning strikes and grid voltage fluctuations.

[0003] Chinese Patent Publication No. CN220358817U discloses a surge protector that is easy to disassemble and maintain, including a guide rail and a surge protector body. The guide rail has several limiting grooves, and the top and bottom of the guide rail are respectively provided with limiting strip one and limiting strip two. The back of the surge protector body has a slot, and the back of the surge protector also has a device slot. The device slot is provided with a snap-fit ​​component for snapping the surge protector body onto the guide rail.

[0004] However, in the aforementioned patent, the snap-fit ​​component needs to cooperate with a specific limiting groove or structure on the guide rail to complete the fixation. Once installed, if the spacing of the surge protector body needs to be adjusted according to the layout changes of other components inside the charging pile, the snap-fit ​​component must be completely disassembled, removed from the guide rail, and then a suitable limiting groove must be found for reinstallation. The whole process requires repeated disassembly and reassembly, making it impossible to achieve direct sliding adjustment along the guide rail. The operation is cumbersome and time-consuming, and it is difficult to adapt to the dynamically changing internal layout requirements of charging piles of different specifications. Based on this, this utility model designs a guide rail type surge protector for charging piles to solve the above problems. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-5A rail-mounted surge protector for charging piles includes a rail 1 and a surge protector body 14. A limit groove 12 is formed on the upper surface of the rail 1, and a slot 10 is formed on the lower surface of the rail 1. A sliding rod 15 is slidably connected to the upper part of the surge protector body 14. A first spring 18 is sleeved on the outer wall of the sliding rod 15, located inside the surge protector body 14. One end of the sliding rod 15 located outside the surge protector body 14 is fixedly connected to a limit groove 12. The limiting block 16 has a chamfer on one side and is engaged inside the limiting groove 12. The limiting block 16 and the limiting groove 12 are slidably connected. A handle 17 is fixedly connected to one end of the sliding rod 15 located outside the surge protector body 14. A locking block 140 is fixedly connected to the lower part of the surge protector body 14. Both the locking groove 10 and the locking block 140 are arc-shaped. The locking block 140 is engaged inside the locking groove 10 and is slidably connected inside the locking groove 10.

[0030] In this embodiment, the locking block 140 below the surge protector body 14 and the locking groove 10 on the lower surface of the guide rail 1 adopt an arc-shaped matching design, which allows for easy insertion without alignment during installation. Combined with the chamfered structure on one side of the limiting block 16, it guides the limiting block 16 to slide into the limiting groove 12 on the upper surface of the guide rail 1, eliminating the need for repeated position adjustments. Compared to the traditional bolt fixing method, this improves installation efficiency.

[0031] A handle 17 is fixedly connected to one end of the sliding rod 15 located outside the surge protector body 14. For disassembly, simply pull the handle 17 to compress the first spring 18, causing the limiting block 16 to disengage from the limiting groove 12. Then, slide it along the slot 10 to remove the surge protector body 14. No screwdrivers, wrenches, or other professional tools are required throughout the process, allowing even non-professionals to perform the operation. This adapts to the on-site maintenance needs of charging piles. The surge protector body 14 achieves dual positioning through the upper limiting block 16 and the limiting groove 12, and the lower slot 140 and the slot 10. Under the restoring force of the first spring 18, the limiting block 16 remains in contact with the inner wall of the limiting groove 12, while the slot 140 perfectly matches the arc-shaped slot 10, limiting the vertical displacement of the surge protector body 14.

[0032] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-5A rail-mounted surge protector for charging piles includes a rail 1 with multiple equidistant positioning holes 13 in the middle. A mounting plate 19 is fixedly connected to one side of the surge protector body 14. A fixing block 2 is fixedly connected to one side of the mounting plate 19. A positioning rod 21 is slidably connected inside the fixing block 2. One end of the positioning rod 21 is engaged inside the positioning hole 13. A second spring 22 is sleeved on the outer wall of the positioning rod 21, located inside the fixing block 2. A pull ring 23 is fixedly connected to the end of the positioning rod 21 outside the fixing block 2. A handle 24 is fixedly connected to one side of the mounting plate 19. Mounting screws 11 are installed at each of the four corners of the rail 1.

[0033] In this embodiment, when adjusting the position of the surge protector body 14, the operator can use a one-handed grip, holding the handle 24 on one side of the mounting plate 19 with the right hand. At this time, the hand naturally fits against the device, and the index finger can easily extend to the pull ring 23 at the end of the positioning rod 21. Pulling the pull ring 23 outward will cause the positioning rod 21 to slide inside the fixing block 2, compressing the second spring 22 and disengaging it from the positioning hole 13 of the guide rail 1. The entire unlocking process does not require the cooperation of both hands or the use of tools. A single hand can complete the continuous action of holding the device stably and pulling to unlock it, greatly reducing the difficulty of operation. It is especially suitable for operation scenarios in the narrow space inside the charging pile.

[0034] Smooth force transmission and effortless sliding adjustment: When the right hand holds the handle 24, a stable gripping force can be applied to the surge protector body 14, preventing the device from shaking during adjustment. Simultaneously, the force of pulling the pull ring 23 outward with the index finger directly acts on the positioning rod 21, unlocking without additional force. After unlocking, simply push or pull the surge protector body 14 gently with the handle 24 to smoothly slide the lower locking block 140 along the locking groove 10 of the guide rail 1 and the upper limiting block 16 along the limiting groove 12 of the guide rail 1. The entire process features a clear force transmission path, requiring minimal effort to operate, and is unlikely to cause hand fatigue even with prolonged repetitive adjustments.

[0035] Working principle: The guide rail 1 serves as the mounting base for the surge protector body 14. It is fixedly connected to the internal mounting surface of the charging pile through the mounting screws 11 at the four corners. During installation, after the guide rail 1 is placed against the mounting surface, the four mounting screws 11 are tightened to ensure that the guide rail 1 is evenly stressed and firmly locked, preventing tilting or loosening during subsequent use and providing a stable reference for the sliding and positioning of the surge protector body 14.

[0036] Below: The locking block 140 at the bottom of the surge protector body 14 is adapted to the locking groove 10 on the lower surface of the guide rail 1. The locking block 140 is inserted into the locking groove 10, and the two form a sliding fit to prevent the surge protector body 14 from falling off the guide rail 1.

[0037] Above: The outer wall of the sliding rod 15 inside the surge protector body 14 is fitted with a first spring 18. Under the natural extension force of the first spring 18, the sliding rod 15 extends outward, causing the end limit block 16 to engage in the limit groove 12 on the upper surface of the guide rail 1. Because the limit block 16 has a chamfer on one side, during installation, the surge protector body 14 can be slightly pushed to make the limit block 16 slide into the limit groove 12 along the chamfer. Finally, the limit block 16 and the limit groove 12 form a sliding fit, preventing the surge protector body 14 from detaching from the guide rail 1 upward.

[0038] With the upper and lower double sliding limiters, the surge protector body 14 can be initially mounted on the guide rail 1 and can slide along the length of the guide rail 1.

[0039] When it is necessary to adjust the position of the surge protector body 14 on the guide rail 1, the operator holds the handle 24 on one side of the mounting plate 19 with his right hand to stabilize the equipment, and at the same time hooks the pull ring 23 at the end of the positioning rod 21 with his index finger and pulls it outward. The pulling force causes the positioning rod 21 to slide inside the fixing block 2, compressing the second spring 22 located inside the fixing block 2, until the end of the positioning rod 21 near the guide rail 1 is completely disengaged from the positioning hole 13 in the middle of the guide rail 1. At this time, the surge protector body 14 is released from position locking and enters the adjustable state.

[0040] Keep the pull ring 23 pulled, push or pull the surge protector body 14 with the handle 24, so that the lower locking block 140 slides along the locking groove 10 of the guide rail 1 and the upper limiting block 16 slides along the limiting groove 12 of the guide rail 1 until the surge protector body 14 moves to the target installation position.

[0041] After reaching the target position, the pull ring 23 is released, and the compressed second spring 22 is reset and extended inside the fixed block 2, generating a thrust in the direction of the guide rail 1, pushing the positioning rod 21 to slide towards the guide rail 1 until the end of the positioning rod 21 close to the guide rail 1 is re-engaged into the corresponding positioning hole 13, completing the position locking of the surge protector body 14. At this time, the equipment enters a stable working state.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
