Description

Technical Field

[0001] This utility model relates to the field of power supply moisture protection technology, and more specifically, it relates to a moisture-proof switching power supply. Background Technology

[0002] In existing technology, power supplies are usually installed in dedicated power supply boxes to ensure safe storage and normal operation. In order to connect with external devices, the power supply box needs to transmit power or signals through external cables. These cables are generally connected to the outside world through openings or interfaces in the power supply box. Although this method can realize the transmission of power between the power supply and the outside world, it often leaves gaps or voids. These gaps are not only physical channels between the power supply box and the outside world, but also allow humid air to easily enter the power supply box. Especially in humid or high-humidity environments, moisture is more likely to enter the box through these gaps.

[0003] Because the connection interface between the power supply box and the outside world is usually not completely sealed, moisture can easily seep into the power supply box, causing the power components to be corroded or affected by moisture. This situation can adversely affect the normal operation of the power supply, and may even lead to short circuits, performance degradation, or corrosion and damage. This phenomenon will be further aggravated in the long-term humid environment, seriously affecting the performance and lifespan of the power supply. Therefore, how to effectively prevent moisture from entering the power supply box and ensure the stability and safety of the power supply has become a major challenge in current power supply design. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a moisture-proof switching power supply to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A moisture-proof switching power supply includes a power supply box and a moisture-proof mechanism. The moisture-proof mechanism is provided in multiple sets, including a fixed cylinder. The fixed cylinder is fixedly connected to the upper end face of the power supply box. A hexagonal ring is sleeved on the outer wall of the fixed cylinder. A circular ring is also sleeved on the outer side of the fixed cylinder. The circular ring is connected to the lower end face of the hexagonal ring. Multiple sets of limiting grooves are opened at the bottom of the inner side wall of the fixed cylinder. A threaded sleeve is threadedly connected to the outer side wall of the fixed cylinder.

[0006] Preferably, the outer wall of the threaded sleeve is connected to a hexagonal cylinder, and the outer wall of the hexagonal cylinder is fitted with a hexagonal sleeve. The hexagonal sleeve is adapted to a hexagonal ring and abuts against the ring. This design, through the cooperation of the hexagonal sleeve and the hexagonal ring, ensures the stability of the external fixing structure and improves the sealing and durability of the moisture-proof switching power supply.

[0007] Preferably, the upper end face of the hexagonal cylinder is connected to multiple sets of connecting rods, and the other end of the connecting rods is connected to a fixing ring. This design strengthens the connection between the hexagonal cylinder and other components, ensures tightness during use, and thus improves the robustness and reliability of the entire moisture-proof structure.

[0008] Preferably, the inner wall of the hexagonal cylinder is connected to multiple sets of elastic plates, and a locking rod is provided in the middle of the elastic plates. The design of the elastic plates and the locking rod achieves the purpose of preventing overload.

[0009] Preferably, a rotating cylinder is rotatably connected to the inner wall of the fixed cylinder, and a retaining ring is connected to the upper end face of the rotating cylinder. Multiple sets of retaining grooves are formed on the outer wall of the retaining ring. The retaining grooves are adapted to the retaining rod. The fixed ring and the retaining ring rotate and abut against each other. Through the rotational abutment between the rotating cylinder and the retaining ring, an efficient connection and locking mechanism is formed.

[0010] Preferably, the lower end face of the rotating cylinder is connected to multiple sets of rubber strips, and the other end is connected to a connecting ring. The upper and lower ends of the rubber strips are provided with inclined grooves. The design of the rubber strips enhances the sealing performance through the inclined grooves, ensuring the isolation of the power supply from the external environment and effectively preventing water vapor penetration.

[0011] Preferably, the lower end face of the connecting ring is connected to multiple sets of limiting rods, the other end of the limiting rod is connected to a limiting ring, the limiting rod is embedded in the limiting groove, and the limiting ring abuts against the lower end face of the fixed cylinder. The design of the limiting rod and the limiting ring restricts the movement of the connecting ring, so that the rubber strip can achieve the purpose of tightening and loosening.

[0012] (III) Beneficial Effects Compared with existing technologies, this utility model provides a moisture-proof switching power supply with the following advantages: Through the moisture-proof mechanism design, the external cable enters the power box through a rotating cylinder. After connecting to the power supply, the connection between the inside of the power box and the outside is sealed. During the sealing process, the tight wrapping of the rubber strip effectively fixes the cable and achieves a comprehensive seal, preventing moisture from seeping into the power box through the interface. The rubber strip fits tightly with the inclined grooves on the upper and lower sides, providing stronger compression force during tightening, further ensuring that there are no gaps or leaks between the cable and the power box, thus effectively blocking the intrusion of humid air. This design makes the installation and removal of the cable easier. Workers can achieve the purpose of tightly fixing the cable and sealing by rotating the hexagonal cylinder. During installation, rotating the hexagonal cylinder drives the threaded sleeve to move down, further driving the rubber strip to rotate and tighten until a complete seal is achieved. When disassembling, simply rotate the hexagonal cylinder in the opposite direction to loosen the rubber strip, making it easy for workers to quickly remove the cable. This process is simple to operate, reduces the complexity of manual operation, and improves the convenience and efficiency of use.

[0013] The design incorporates overload protection. Once rotated to the correct position, the hexagonal cylinder's rotation compresses the elastic plate. Under pressure, the elastic plate's displacement via the locking lever provides overload protection. If the rotation exceeds the predetermined position, the locking lever slides out of its current slot and into another slot, preventing damage to the moisture-proof system from over-tightening or other improper operation. This protection mechanism not only ensures the stability of the moisture-proof function but also effectively avoids malfunctions or damage caused by excessive operation. In summary, the moisture-proof switching power supply design features moisture resistance, convenient installation and disassembly, and an overload protection mechanism, effectively improving power supply reliability, extending service life, and ensuring stable operation under various environmental conditions.

[0019] Please see Figures 1-5 A moisture-proof switching power supply includes a power supply box 11 and a moisture-proof mechanism. The moisture-proof mechanism comprises multiple sets, including a fixed cylinder 21, which is fixedly connected to the upper surface of the power supply box 11. A hexagonal ring 22 is fitted onto the outer wall of the fixed cylinder 21, and a circular ring 23 is also fitted onto the outer side of the fixed cylinder 21, with the circular ring 23 connected to the lower surface of the hexagonal ring 22. Multiple sets of limiting grooves 24 are formed at the bottom of the inner wall of the fixed cylinder 21. A threaded sleeve 25 is threadedly connected to the outer wall of the fixed cylinder 21, and a hexagonal cylinder 26 is connected to the outer wall of the threaded sleeve 25. A hexagonal sleeve 27 is fitted onto the outer wall of the hexagonal cylinder 26, which is adapted to the hexagonal ring 22 and abuts against the circular ring 23. Multiple sets of connecting rods 28 are connected to the upper surface of the hexagonal cylinder 26, and the other end of each connecting rod 28 is connected to a fixed ring 29. The inner surface of the hexagonal cylinder 26... Multiple sets of elastic plates 210 are connected to the side wall. A locking rod 211 is provided in the middle of the elastic plate 210. A rotating cylinder 212 is rotatably connected to the inner side wall of the fixed cylinder 21. A retaining ring 213 is connected to the upper end face of the rotating cylinder 212. Multiple sets of retaining grooves 214 are opened on the outer side wall of the retaining ring 213. The retaining grooves 214 are adapted to the locking rod 211. The fixed ring 29 rotates and abuts against the retaining ring 213. Multiple sets of rubber strips 215 are connected to the lower end face of the rotating cylinder 212. A connecting ring 216 is connected to the other end. The rubber strips 215 have inclined grooves 217 at both the upper and lower ends. Multiple sets of limiting rods 218 are connected to the lower end face of the connecting ring 216. A limiting ring 219 is connected to the other end of the limiting rod 218. The limiting rod 218 is embedded in the limiting groove 24. The limiting ring 219 abuts against the lower end face of the fixed cylinder 21.

[0020] In this utility model, a power supply box 11 houses a power source, which is connected to an external cable via a moisture-proof mechanism to achieve effective moisture protection. Specifically, when connecting an external cable to the power source, the cable is passed through the rotating cylinder 212 located above the power supply box 11 before being connected to the power source. After the cable is passed through the rotating cylinder 212, the operator needs to manually slide the hexagonal sleeve 27 upwards to release it from the hexagonal ring 22. Then, the operator can manually rotate the hexagonal cylinder 26, which drives the threaded sleeve 25 connected to its inner side to rotate, causing the threaded sleeve 25 to rotate and move downwards along the fixed cylinder 21. The fixed cylinder 21 is fixedly connected to the power supply box 11 because of its inner limiting groove 21. 4. An inner retaining rod 218 is engaged. The retaining rod 218 connects to the connecting rings 216 and 219 on its upper and lower sides, which do not rotate. During the downward rotation of the threaded sleeve 25, the hexagonal cylinder 26 will also move downward. Because the retaining rod 211 in the middle of the multiple sets of elastic plates 210 on the inner side of the hexagonal cylinder 26 is engaged in the retaining groove 214, the rotation of the hexagonal cylinder 26 will drive the retaining ring 213 to rotate. The retaining ring 213 will drive the rotating cylinder 212 to rotate synchronously. In turn, the rotating cylinder 212 can drive the multiple sets of rubber strips 215 connected below to rotate and tighten. Because one end of the rubber strip 215 can rotate and the other end is fixed, the rubber strip 215 will tighten more and more. The inner cable is wrapped and secured. Since each rubber strip 215 has beveled grooves 217 on both the top and bottom, during tightening, the upper beveled groove 217 of the rubber strip 215 will tightly fit with the lower beveled groove 217 of the upper rubber strip 215, and vice versa. This achieves a seal while the rubber strip 215 wraps and secures the cable. The operator rotates the hexagonal cylinder 26 until the rubber strip 215 is fully tightened and cannot be rotated further. Continuing to rotate the hexagonal cylinder 26 at this point will damage the cable. The elastic sheet 210 is compressed, and the pressure on the elastic sheet 210 causes the locking rod 211 to slide into the locking groove 214, so that the locking rod 211 slides into the locking groove 214 on the other side, achieving the purpose of preventing overload. After rotating into place, the operator slides the hexagonal sleeve 27 down to fit it onto the hexagonal cylinder 26 and the hexagonal ring 22 and abuts against the ring 23. At this time, the hexagonal cylinder 26 and the hexagonal ring 22 are fixed, thereby achieving the sealed installation of the cable. When it is necessary to disassemble the cable, the operator only needs to slide the hexagonal sleeve 27 up again, and then rotate the hexagonal cylinder 26 in the opposite direction. The locking rod 211 drives the rotating cylinder 212 to rotate, so that the multiple sets of rubber strips 215 are gradually released from the tightened state.
