Description

Technical Field

[0001] This utility model relates to the field of power transformers, and in particular to a power transformer that is free from external damage. Background Technology

[0002] A power transformer is a static electrical device used to convert an alternating voltage (current) of a certain value into one or more different voltages (currents) at the same frequency. It is a static device with two or more windings that, in order to transmit electrical energy, converts the alternating voltage and current of one system into the voltage and current of another system through electromagnetic induction at the same frequency. Usually, the values ​​of these currents and voltages are different.

[0003] Currently used power transformers are typically installed using screws and tools. While this method can install power transformers, it requires the assistance of tools for both installation and disassembly, reducing the inconvenience and efficiency of power transformer installation. Therefore, we propose a power transformer that is free from external damage to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a power transformer that is free from external damage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An externally-protected power transformer includes a base, a protective component on the upper surface of the base, a support component inside the protective component, a limiting component on the bottom surface of the base, and a power transformer body inside the protective component.

[0007] In a further embodiment, the upper surface of the base has two sliding grooves and four holes.

[0008] In a further embodiment, the protective component includes a housing, the front of which is hinged to a protective door, a slot is provided inside the housing, and the bottom surface of the housing is connected to the upper surface of the base.

[0009] In a further embodiment, the support includes a support plate, a locking block connected to the back of the support plate, two sliders connected to the bottom surface of the support plate, four limiting holes opened on the outer surface of the support plate, the outer surface of each slider being slidably connected to the inner wall of the groove, the outer surface of the locking block being adapted to the inside of the groove, and the bottom surface of the power transformer body being connected to the upper surface of the support plate.

[0010] In a further embodiment, the limiting member includes two U-shaped shells, each U-shaped shell having two fixing holes on its outer surface, each fixing hole having a limiting rod slidably connected inside, the outer surfaces of the two limiting rods being connected to a limiting plate, each limiting rod having a spring sleeved on its outer surface, the end of each spring near the limiting plate being connected to the upper surface of the limiting plate, and the end of each spring away from the limiting plate being connected to the bottom surface of the base.

[0011] In a further embodiment, the top of the limiting rod passes through the perforation and the limiting hole in sequence and extends to the top of the support plate. The upper surface of each U-shaped shell is connected to the bottom surface of the base, and the bottom ends of the two limiting rods are connected to a handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, by pulling the handle, moves the limiting rod and limiting plate downwards. Simultaneously, the limiting plate stretches the spring, allowing the limiting rod to quickly disengage from the hole. Through the cooperation of the locking block and the locking slot, the limiting hole in the support plate can quickly align with the hole and the limiting hole. By releasing the handle, the spring is no longer under pressure, and its own elasticity drives the limiting rod and the limiting plate to move, allowing the limiting rod to pass through the hole and the limiting hole in sequence. This ensures the stability of the support plate during installation and the convenience of installing the power transformer body. Attached Figure Description

[0021] The upper surface of the base 1 has two sliding grooves 101 and four holes 102. The protective component 2 includes a housing 201. The front of the housing 201 is hinged with a protective door 202. The inside of the housing 201 has a slot 203. The bottom of the housing 201 is connected to the upper surface of the base 1. Through the cooperation of the housing 201 and the protective door 202, the power transformer body 5 can be prevented from being damaged by external forces, and the power transformer body 5 can be effectively protected. At the same time, the outer surface of the housing 201 has ventilation grooves and the back has pre-set holes, which can respectively allow airflow inside the housing 201 and connect the power cord to the power transformer body 5.

[0022] Support member 3 includes a support plate 301. A locking block 302 is connected to the back of the support plate 301. Two sliders 303 are connected to the bottom surface of the support plate 301. Four limiting holes 304 are formed on the outer surface of the support plate 301. The outer surface of each slider 303 is slidably connected to the inner wall of the groove 101. The outer surface of the locking block 302 is adapted to the interior of the groove 203. The bottom surface of the power transformer body 5 is connected to the upper surface of the support plate 301. Limiting member 4 includes two U-shaped shells 401. Two fixing holes 402 are formed on the outer surface of each U-shaped shell 401. A limiting rod 403 is slidably connected inside each fixing hole 402. The outer surfaces of the two limiting rods 403 are connected to a limiting plate 404. A spring 405 is sleeved on the outer surface of each limiting rod 403. One end of each spring 405 near the limiting plate 404 is connected to the upper surface of the limiting plate 404. The ends of the 405s away from the limiting plate 404 are connected to the bottom surface of the base 1. The top of the limiting rod 403 passes through the hole 102 and the limiting hole 304 in sequence and extends to the top of the support plate 301. The upper surface of each U-shaped shell 401 is connected to the bottom surface of the base 1. The bottom ends of the two limiting rods 403 are connected to the handle 406. Through the spring 405, based on the extensibility and elasticity of the spring 405, it can be extended with the limiting plate 404 under force, and can also quickly reset the limiting plate 404 and the limiting rod 403 without force. Through the setting of the locking block 302 and the locking groove 203, when the locking block 302 is locked into the locking groove 203, the limiting hole 304 will be aligned with the hole 102 and the fixing hole 402 without calibration, improving the convenience when installing the power transformer body 5. Through the setting of the handle 406, it is convenient for the staff to quickly pull the limiting rod 403 to move.

[0023] The working principle of this utility model is as follows:

[0024] During installation, first open the protective door 202 and pull down the handle 406. The handle 406 will cause the limiting rod 403 to slide inside the hole 102 and the fixing hole 402. The limiting rod 403 will then move the limiting plate 404 and stretch the spring 405. Next, lift the support plate 301 so that the slider 303 slides into the groove 101. The support plate 301 will slide with the slider 303 and move the power transformer body 5. After the support plate 301 slides into the outer casing 201, the locking block 302 will engage with the outer casing 201. The slot 203 engages, and then the limiting hole 304 will automatically align with the cut hole 102 and the fixing hole 402. Then, release the handle 406, and the spring 405 will pull the limiting plate 404 and the limiting rod 403 back to their original positions according to its elasticity. The limiting rod 403 will slide inside the fixing hole 402 and pass through the cut hole 102 and the limiting hole 304 in sequence. Finally, the protective door 202 will close, limiting the support plate 301. This increases the efficiency of the power transformer body 5 during installation. When disassembling, the above steps can be followed for quick disassembly.
