Description

Technical Field

[0001] This utility model relates to the field of isolation transformer installation technology, and in particular to a low-noise isolation transformer that is easy to install. Background Technology

[0002] In power systems, industrial production, and civil construction, transformers, as core equipment for power conversion and transmission, directly impact the overall quality of power supply through their operational stability, safety, and environmental friendliness. With the continuous growth of societal demand for electricity and the increasing requirements for equipment operating noise and installation efficiency, isolation transformers, due to their advantages such as electrical isolation and interference suppression, are widely used in scenarios with high requirements for power supply reliability and safety, such as medical equipment, precision instruments, and data centers.

[0003] Existing isolation transformers are typically equipped with isolation boxes to achieve protection and noise isolation functions, but there are still obvious shortcomings in practical applications. In terms of installation, the installation and assembly of traditional isolation boxes often rely on complex connector combinations. The sealing and fixing of the top plate and the isolation box requires multiple adjustments of the bolt positions, and the docking and positioning of the isolation box and the base lacks convenient guiding and locking structures, resulting in a long installation process that requires the cooperation of multiple operators, which greatly reduces assembly efficiency. In order to address this technical problem, this application proposes a low-noise isolation transformer that is easy to install. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-noise isolation transformer that is easy to install. The isolation box can be easily hoisted onto the base using a hook, allowing the fixed mounting legs to be quickly inserted into the mounting slots for initial positioning. By rotating the rotating rods at both ends of the isolation box, the protrusions and movable mounting legs can be moved and the second spring can be compressed. After the movable mounting leg is placed into the corresponding mounting slot, the restoring force of the second spring can firmly insert it into the slot, achieving a stable connection between the isolation box and the base. This eliminates the need for complex operations and improves overall assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-noise isolation transformer that is easy to install, comprising an isolation box, wherein multiple fixing rods are fixedly connected to the outer periphery of the top of the isolation box, a limiting block is fixedly connected to the outer wall of the fixing rods, a top plate is sleeved on the outer wall of the fixing rods and the top plate is located above the limiting block, multiple fixing rods are fixedly connected to the outer periphery of the bottom of the top plate, a sealing plate is slidably connected to the bottom of the fixing rods, a fan is installed in the middle of the sealing plate, a base is provided at the bottom of the isolation box, two mounting slots are opened at the bottom of the base, a movable mounting leg is provided in the right mounting slot, the front and rear ends of the movable mounting leg are connected to the isolation box through limiting components, and a fixed mounting leg is fixedly connected to the left side of the bottom of the isolation box.

[0006] Furthermore, the limiting component includes protrusions fixedly connected to both ends of the movable mounting leg, and multiple limiting rods are slidably connected to the top of the movable mounting leg. The limiting rods are fixedly connected to the isolation box, and a second spring is sleeved on the left side of the limiting rod. One end of the second spring is connected to the movable mounting leg, and the other end of the second spring is connected to the isolation box.

[0007] Furthermore, a rotating rod is rotatably connected to the bottom end of the isolation box, and a baffle is provided on the left side of the rotating rod, which is fixedly connected to the isolation box.

[0008] Furthermore, two slide rails are fixedly connected to the inner walls of both the left and right ends of the isolation box, and filter plates are slidably connected to the adjacent sides of the two slide rails. Multiple through grooves are opened on the outer walls of both the left and right ends of the isolation box.

[0009] Furthermore, a spring is sleeved on the outer wall of the fixing rod, one end of the spring is connected to the bottom side of the top plate, and the other end of the spring is connected to the top side of the sealing plate.

[0010] Furthermore, hooks are installed around the top of the isolation box, and the hooks penetrate the top plate.

[0011] Furthermore, the transformer body is bolted to the bottom inner wall of the isolation box.

[0012] Furthermore, a rotating door is rotatably connected to the front side of the isolation box.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the isolation box can be easily hoisted to the top of the base by means of a hook, so that the fixed mounting legs can be quickly inserted into the mounting slots to complete the initial positioning. By rotating the rotating rods at both ends of the isolation box, the protrusion and the movable mounting legs can be moved and the second spring can be compressed. After the movable mounting legs are put into the corresponding mounting slots, the restoring force of the second spring can firmly insert them into the slots, realizing a stable connection between the isolation box and the base. No complicated operation is required, which improves the overall assembly efficiency.

[0014] 2. In this utility model, when installing the top plate, the process of screwing the bolt into the fixing rod two drives the top plate to move down. This not only allows the top plate to make precise contact with the limiting block to achieve positioning, but also compresses the spring one at the same time. The continuous elastic force generated by the spring one can make the sealing plate fit tightly with the top of the isolation box, effectively reducing the possibility of external dust, water vapor and other impurities entering the isolation box, avoiding the transformer body from malfunctioning due to external environmental interference, and providing good sealing protection conditions for the long-term stable operation of the transformer.

Detailed Implementation

[0017] 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.

[0018] Reference Figure 1-3This utility model provides an embodiment of a low-noise isolation transformer that is easy to install. It includes an isolation box 1. Multiple fixing rods 11 are fixedly connected to the outer periphery of the top of the isolation box 1. The fixing rods 11 can cooperate with bolts to install a top plate 3 onto the fixing rods 11. Limiting blocks 21 are fixedly connected to the outer walls of the fixing rods 11. The limiting blocks 21 limit the movement of the top plate 3. The top plate 3 is fitted onto the outer walls of the fixing rods 11 and is located above the limiting blocks 21. The area of ​​the top plate 3 is larger than the top of the isolation box 1. The top plate 3 has multiple fixing rods 9 fixedly connected to its bottom outer perimeter. A sealing plate 7 is slidably connected to the bottom end of each fixing rod 9. During installation, the sealing plate 7 seals the top of the isolation box 1. When the sealing plate 7 contacts the isolation box 1, it compresses a spring 10, improving the tightness of the contact between the sealing plate 7 and the isolation box 1. A fan 8 is installed in the middle of the sealing plate 7. When the fan 8 operates, it draws away heat from the isolation box 1, thereby reducing the heat inside the isolation box 1. The heat insulation box 1 has a base 5 at its bottom. Two mounting slots 15 are formed at the bottom of the base 5. The width of the mounting slots 15 is greater than the width of the fixed mounting leg 14 and the movable mounting leg 16, while the height of the mounting slots 15 is less than the height of the fixed mounting leg 14 and the movable mounting leg 16. A movable mounting leg 16 is installed in the right mounting slot 15. Both ends of the movable mounting leg 16 are fixedly connected to protrusions 18. Moving the protrusions 18 moves the movable mounting leg 16. The top of the movable mounting leg 16 slides. Multiple limiting rods 17 are connected to limit the movement of the movable mounting leg 16. The limiting rods 17 are fixedly connected to the isolation box 1. A second spring 20 is sleeved on the left side of the limiting rod 17. One end of the second spring 20 is connected to the movable mounting leg 16. After the movable mounting leg 16 is placed into the mounting groove 15, the second spring 20 can make the movable mounting leg 16 automatically insert into the mounting groove 15. The other end of the second spring 20 is connected to the isolation box 1. A fixed mounting leg 14 is fixedly connected to the bottom left side of the isolation box 1.

[0019] Reference Figure 3-4The isolation box 1 has a rotating rod 6 rotatably connected to its bottom end. A baffle 19 is provided on the left side of the rotating rod 6 and is fixedly connected to the isolation box 1. Rotating the rotating rod 6 allows its bottom end to contact the protrusion 18, pushing the protrusion 18 and thus moving the movable mounting leg 16. Two slide rails are fixedly connected to the inner walls of both ends of the isolation box 1. Filter plates 13 are slidably connected to the adjacent side of the two slide rails. The filter plates 13 can filter the air entering the isolation box 1 from the through groove. Multiple through grooves are provided on the outer walls of both ends of the isolation box 1. A spring 10 is sleeved on the outer wall of the fixing rod 9. One end of the spring 10 is connected to the bottom side of the top plate 3, and the other end of the spring 10 is connected to the top side of the sealing plate 7. The spring 10 can improve the tightness of the contact between the sealing plate 7 and the isolation box 1. Hooks 4 are installed around the top of the isolation box 1 and penetrate the top plate 3. The hooks 4 can be used to lift the entire device. The transformer body 12 is bolted to the inner wall of the bottom of the isolation box 1. The transformer body 12 is a common low-noise transformer on the market. A rotating door 2 is rotatably connected to the front of the isolation box 1.

[0020] Working principle: First, the transformer body 12 is placed into the isolation box 1 from the top and fixed inside the isolation box 1 with bolts. Then, the top plate 3 is placed on the top of the isolation box 1, so that the sealing plate 7 contacts the top of the isolation box 1. Then, the bolts are tightened to the outer wall of the fixing rod 11. During the tightening process, the top plate 3 will move downwards until it contacts the limit block 21. During this process, the top plate 3 will compress the spring 10, so that the sealing plate 7 can fit more tightly against the top side of the isolation box 1. Then, multiple hooks 4 are passed through the top plate 3 and screwed to the top side of the isolation box 1. The isolation box 1 can be lifted by the multiple hooks 4 and hoisted to the top. Above the base 5, the fixed mounting leg 14 is inserted into the mounting slot 15. Then, the rotating rods 6 at both ends of the isolation box 1 are rotated. When the rotation reaches a certain position, the bottom end of the rotating rod 6 can contact the protrusion 18, thereby pushing the protrusion 18 to the left, and thus moving the movable mounting leg 16 to the left. The movable mounting leg 16 can compress the second spring 20. Then, the movable mounting leg 16 is placed into another mounting slot 15. The rotating rod 6 is released, and the second spring 20 can push the movable mounting leg 16 to the right, thereby inserting the movable mounting leg 16 into the mounting slot 15, thus completing the installation of the isolation box 1 onto the base 5.
