[0002] A redundant power supply is a system designed to provide a continuous and stable power supply, ensuring continued power to equipment or systems even in unforeseen circumstances. A redundant power supply system typically consists of two or more power sources that work together to provide backup power. Redundant power supplies are commonly used in systems requiring long-term uninterrupted operation and high reliability, such as base station communication equipment, monitoring equipment, and servers. These systems often demand highly reliable power supplies, and redundant power supplies play a crucial role in this process. In particular, the design of redundant power supplies ensures uninterrupted operation of switches, improving network availability.

[0003] Existing redundant industrial power supplies typically involve first installing appropriately sized sliding rails inside the power supply box, and then fixing the power supply to the rails using metal hooks. However, this method requires external hooks for installation, resulting in poor support and increased operating costs. Furthermore, to save space, existing industrial power supplies are often installed close together, which not only affects heat dissipation but also makes disassembly and installation inconvenient, thus limiting their practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a redundant industrial power supply, including a power supply body 1, an outer shell 2 covering the power supply body 1, and heat dissipation components 3 on both sides of the outer shell 2. The heat dissipation components 3 are composed of a support plate 31 and heat sinks 32, wherein the support plate 31 and the heat sinks 32 are both metal sheets made of thermally conductive material. A plurality of second heat dissipation holes 22 are evenly opened on one side of the heat dissipation components 3, which can not only increase the heat dissipation effect of the power supply body 1, but also maintain a certain aesthetic appearance.

[0024] Meanwhile, the support plate 31 is set as a T-shaped structure, and the bottom is fixedly connected to the outer wall of the outer shell 2. Two heat sinks 32 are fixedly connected to both sides of the support plate 31. A gap is set between the two heat sinks 32 to form a flow guide groove. In this way, when multiple power supply bodies 1 are installed, the distance between the power supply bodies 1 can be maintained, so as not to affect the normal heat dissipation requirements. At the same time, the flow guide groove and heat sink 32 are set to facilitate better heat dissipation effect.

[0025] The upper and lower surfaces of the outer casing 2 are provided with several first heat dissipation holes 21. The rear end of the outer casing 2 is provided with a mounting groove 4. The bottom of the mounting groove 4 is provided with a movable groove 41. The mounting groove 4 is a U-shaped groove structure. An inclined slot 44 is provided at the top of the mounting groove 4 and inside the outer casing 2 to facilitate hanging the power supply body 1 on the metal plate slide. At the same time, a retaining plate 43 is movably connected in the movable groove 41 by a pin 42. The center of the retaining plate 43 is fitted onto the pin 42 and movably connected. The top of the retaining plate 43 is a sloping structure and extends into the mounting groove 4. The other end of the retaining plate 43 is provided with two elongated push-pull grooves 403, and the two push-pull grooves 403 are correspondingly set so that the retaining plate 43 can be used to further limit and fix the position of the power supply body 1 to prevent displacement.

[0026] A push-pull mechanism 5 is connected to the card plate 43. The push-pull mechanism 5 consists of a push rod 51, an adjusting nut 52, a spring 53, a positioning ring 54, and a support ring 55. The push rod 51 is a Y-shaped metal rod. The outer wall of the other end of the push rod 51 is provided with an external thread and is screwed to the adjusting nut 52, so that the position of the adjusting nut 52 on the push rod 51 can be further adjusted. At the same time, the U-shaped end of the push rod 51 is embedded in the push-pull groove 403 and slidably connected. The push rod 51 is placed in the positioning ring 54 and the support ring 55 and slidably connected. The diameter of the positioning ring 54 and the support ring 55 is larger than the diameter of the push rod 51. Thus, the movement of the push rod 51 can further drive the rotation of the card plate 43.

[0027] Meanwhile, the positioning ring 54 is fixedly installed at the bottom of the outer shell 2, and the support ring 55 is fixedly installed at the bottom of the outer shell 2 located at the front end of the power supply body 1. The spring 53 is sleeved on the push rod 51, and the two ends of the spring 53 are respectively attached to the inner wall between the positioning ring 54 and the clamping plate 43. In this way, the clamping plate 43 can be fixed to the installation position of the power supply body 1 by the elasticity of the spring 53 itself, and the clamping plate 43 can be loosened by the movement of the push rod 51.

[0028] Working principle: When using this utility model, the push rod 51 is first placed inside the positioning ring 54 and the support ring 55. The U-shaped end of the push rod 51 is embedded in the push-pull groove 403 at the bottom of the card plate 43. At the same time, a spring 53 is sleeved on the other end of the push rod 51 and an adjusting nut 52 is screwed on. When the power supply body 1 is installed, it can be hung on the metal plate slide through the card slot 44 and pressed and fixed by the card plate 43 at the bottom. At the same time, support plates 31 are fixedly installed on both sides of the outer shell 2, and heat sinks 32 are fixedly installed on both sides of the support plates 31. This not only maintains the spacing between several power supply bodies 1, but also maintains better air circulation, thereby maintaining a good heat dissipation effect. When disassembly is required, the push rod 51 can be pulled to further rotate the card plate 43, thereby loosening the fixation of the slide. This makes it easier to disassemble and use the power supply body 1, making it more practical.
