Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a small transformer with good waterproof performance. Background Art

[0002] Modern transformers need to be used in various devices to change and control the voltage through the transformer itself. Traditional transformers are mostly directly installed on the inside of the main power connection device to achieve the effect of fixing the transformer. However, transformers often need to adapt to different environments. Traditional transformers have deficiencies in this aspect that need to be improved.

[0003] In the prior art, for example, announcement number CN217214348U proposes a waterproof small transformer. The present technical solution discloses a waterproof small transformer, including a waterproof shell and a chimeric frame, wherein the waterproof shell is equipped with a chimeric frame; a sealing cover is installed on the right side of the waterproof shell; a chimeric disk is installed on the right side of the waterproof shell, and the chimeric disk is located on the inner side of the sealing cover. The present utility model is equipped with a waterproof shell, and the sealing rubber ring on the right side of the waterproof shell is embedded in the combination groove of the sealing cover, which can greatly increase the sealing effect of the device and prevent external water from entering the interior of the device. The sealing cover is then installed in the threaded groove on the right side of the sealing rubber ring by using a fixing knob, thereby achieving the effect of sealing and assembling the device. The good sealing performance of the disassembly port connection can effectively waterproof the device, so that the device can adapt to more environments and prevent short circuits.

[0004] However, the small transformer of the prior art solution improves the waterproofness of the small transformer by arranging a waterproof shell on the outer wall, but there is no buffer component inside the waterproof shell, so that the small transformer cannot play a buffering and protective role when it is hit during operation, which can easily cause damage to the transformer, thereby affecting the normal use of the transformer;

[0005] In order to solve the above problems, the present application proposes a small transformer with good waterproof performance. Utility Model Content

[0006] The utility model aims to provide a small transformer with good waterproof performance, which is mainly used to solve the problem that the existing small transformer cannot play a buffering and protective role when it is hit, which easily causes damage to the transformer, thereby affecting the normal use of the transformer.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A small transformer with good waterproof performance comprises a shell and a transformer body installed inside the shell, a sealing cover is connected to the opening of the shell, limit assemblies are arranged on both sides of the sealing cover, a buffer assembly is slidably connected inside the sealing cover, a first damping rod is fixedly connected to the side of the inner wall of the shell away from the sealing cover, the other end of the first damping rod is fixedly connected to the first buffer plate, the first buffer plate is slidably connected to the inner wall of the shell, a first spring is sleeved on the outer wall of the first damping rod, one end of the first spring is fixedly connected to the first buffer plate, and the other end is fixedly connected to the inner wall of the shell.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the small transformer is in use, install the transformer body into the shell, and then install the sealing cover to one side of the shell. At the same time, pass the line on the transformer body through the hose on the sealing cover. After the sealing cover is installed on the shell, it can be fixed by the limit assembly. Then the small transformer can be used normally.

[0011] 2. Beneficial effect: After the sealing cover is installed on the shell, it can be fixed by the limit assembly, which not only makes the sealing of the shell better, but also makes the disassembly and assembly of the sealing cover more convenient. During the operation of the transformer body inside the shell, the first damping rod, the first spring, the first buffer plate and the buffer assembly inside the sealing cover cooperate to provide better buffer protection for the transformer body, thereby effectively extending the service life of the small transformer.

[0012] Preferably, the limiting assembly includes symmetrical sliding cavities on both sides of the sealing cover, the interior of the sliding cavities is slidably connected to wedge blocks, the sealing cover is extended from one side of the wedge block, and the other end is fixedly connected to a second spring, the other end of the second spring is fixedly connected to the inner wall of the sliding cavity, a limiting groove matching the wedge block is provided on the shell, a pressing block is slidably connected to the interior of the limiting groove, one side of the pressing block extends out of the shell, and the other side is fixedly connected to a symmetrical pushing block, the side of the pushing block away from the pressing block is arranged to abut against the wedge block, and when the sealing cover is inserted into the shell, the wedge block is squeezed to move toward the inside of the sliding cavity, and at the same time squeezes the second spring to put it in a compressed state. When the sealing cover is fully inserted into the shell, the sealing cover will be tightly pressed against the sealing strip at the shell opening, and the wedge block will pop out under the action of the second spring and engage with the limit groove, so as to better fix the sealing cover. At this time, the small transformer can be used normally. When the sealing cover needs to be removed, the pressing blocks on both sides of the sealing cover can be pressed at the same time to push the wedge block to move into the sliding cavity through the pushing block. When the wedge block completely enters the sliding cavity, the sealing cover can be removed from the shell. This not only makes the sealing of the shell better, but also makes the disassembly and assembly of the sealing cover more convenient, thereby making it convenient for people to inspect the transformer body inside the shell.

[0013] Preferably, the buffer assembly includes a second buffer plate slidably connected to the inside of the sealing cover, one side of the second buffer plate extends out of the sealing cover and is arranged against the transformer body, and the other side is fixedly connected with a second damping rod, the other end of the second damping rod is fixedly connected to the inner wall of the sealing cover, and the outer wall of the second damping rod is sleeved with a third spring, one end of the third spring is fixedly connected to the second buffer plate, and the other end is fixedly connected to the inner wall of the sealing cover. When the transformer body inside the shell generates certain vibrations or is hit during operation, the second buffer plate, the second damping rod and the third spring arranged inside the sealing cover can provide better buffering protection for the transformer body.

[0014] Preferably, a slider is fixedly connected to one side of the push block, and a slide groove matching the slider is provided on the inner wall of the limit groove. When the pressing block and the push block slide in the limit groove, the slider arranged on one side of the push block and the slide groove provided in the limit groove can play a better limiting and guiding role for the pressing block and the push block. This not only makes the pressing block and the push block more stable when sliding in the limit groove, but also effectively prevents the pressing block and the push block from detaching from the limit groove, thereby effectively ensuring the normal use of the device.

[0015] Preferably, the number of the first damping rod and the number of the second damping rod are both four. By setting the number of the first damping rod and the number of the second damping rod to four, the transformer body inside the shell can have a better buffering effect when the transformer body is in operation.

[0016] Preferably, the first buffer plate and the second buffer plate are fixedly connected to a rubber pad on one side close to the transformer body. Since the rubber material is relatively soft, the rubber pads arranged on the first buffer plate and the second buffer plate on the side close to the transformer body can avoid hard contact between the transformer body and the first buffer plate and the second buffer plate, thereby providing better buffering protection for the transformer body and further extending the service life of the transformer body.

[0017] Preferably, the corners of the pressing block extending out of one side of the shell are all rounded. By setting the corners of the pressing block extending out of one side of the shell to be rounded, not only can people's hands be more comfortable when pressing the pressing block, but the corners of the pressing block can also be effectively prevented from scratching people's hand skin.
