Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1, an embodiment provided by the present utility model: A transformer with a good sealing structure, including a transformer main body 1, the lower surface of the transformer main body 1 is fixedly connected with a transformer base 4, and the transformer base 4 can provide support for the overall device and facilitate the fixation of the device. The upper surface of the transformer main body 1 is provided with a transformer top plate 2, the upper surface of the transformer top plate 2 is provided with a winding 5, and the upper surface of the transformer top plate 2 is provided with a terminal 6. The transformer main body 1, the transformer top plate 2, the transformer base 4, the winding 5 and the terminal 6 together form a transformer. The transformer is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. The front surface of the terminal 6 is provided with a sealing component, which can maintain the seal and prevent rainwater from seeping in, and can keep the terminal 6 and the winding 5 in a dry state to ensure their normal operation. The upper surface of the transformer top plate 2 is provided with a protection component, which can protect the terminal 6 and the winding 5 and also maintain the sealed state of the terminal 6 and the winding 5.
[0032] Referring to Figures 2 - 3 , the protection component includes a protection cover 35, the outer wall of the protection cover 35 is fixedly connected with a sealing gasket 36. The sealing gasket 36 is a plate with a relatively hard material as a whole, but the bottom surface is made of rubber material. When the protection cover 35 is installed on the transformer top plate 2, the sealing gasket 36 will closely fit with the transformer top plate 2 to form a seal. A slot 302 is opened on the front surface of the protection cover 35. The protection component further includes a clamping block 33, the slot 302 and the clamping block 33 are fitted, the right surface of the clamping block 33 is fixedly connected with a sliding block 34, and the clamping block 33 and the sliding block 34 will move synchronously. A plurality of groups of clamping blocks 33 are provided and are symmetrically distributed before and after with the center line of the transformer top plate 2 as the axis. A sliding slot 301 is opened on the inner wall of the right side of the transformer top plate 2, and the sliding slot 301 and the sliding block 34 are fitted. The upper surface of the transformer top plate 2 is elastically connected with a positioning ring 31 through a compression spring 32.
[0033] Referring to Figure 1 , Figure 4 , the sealing component includes a connecting wire 71, the front surface of the protection cover 35 is penetrated and fixedly connected with a fixing ring 72, the inner wall of the fixing ring 72 is rotatably connected with a gasket 73, and the inner wall of the gasket 73 is fixedly connected with a rubber gasket 74. A plurality of groups of fixing rings 72 are provided and are evenly distributed horizontally on the front surface of the protection cover 35.
[0034] Referring to Figures 2 - 3, the protective cover 35 is inserted into the upper surface of the transformer top plate 2. The gasket 36 is located above the card slot 302. The card slot 302 is formed in an arc shape. The card block 33 penetrates and is slidably connected to the front surface of the transformer top plate 2. The slider 34 is slidably connected to the inner wall of the chute 301. The card block 33 and the slider 34 slide in the front-back direction. There are multiple groups of chutes 301, and there are multiple groups of sliders 34. The multiple groups of chutes 301 and sliders 34 are symmetrically distributed about the center line of the card block 33. The front surface of the card block 33 is formed in an arc shape, and the rear surface of the card block 33 is formed in an arc shape. Squeezing the arc surface of the front surface of the card block 33, the card block 33 will move backward. Squeezing the arc surface of the rear surface of the card block 33, the card block 33 will move forward. The card block 33 is inserted into the inner wall of the card slot 302, which can limit the position of the protective cover 35. One end of the compression spring 32 is fixedly connected to the lower surface of the positioning ring 31, and the other end of the compression spring 32 is fixedly connected to the upper surface of the transformer top plate 2. When the positioning ring 31 moves downward, it will squeeze the compression spring 32 to generate a reaction force. The positioning ring 31 is slidably connected to the outer wall of the transformer top plate 2.
[0035] Refer to Figure 1 , Figure 4 , the connecting wire 71 is arranged on the front surface of the terminal block 6. The connecting wire 71 is connected to an external component. The connecting wire 71 penetrates the front surface of the gasket 73. The rubber pad 74 is in contact with the outer wall of the connecting wire 71. The rubber pad 74 is in close contact with the outer wall of the connecting wire 71, which can maintain the seal and prevent rainwater from seeping in.
[0036] Working principle: When the device is in use, first move the protective cover 35 above the transformer top plate 2, and then pass the connecting wire 71 through the gasket 73. At this time, the rubber pad 74 will be in contact with the connecting wire 71, which can prevent rainwater from seeping in from the gasket 73.
[0037] Then move the positioning ring 31 downward. The downward moving positioning ring 31 will release the blockage of the card block 33 and will squeeze the compression spring 32 to generate a reaction force. Then insert the protective cover 35 into the upper surface of the transformer top plate 2. When inserting, the protective cover 35 will squeeze the arc surface of the card block 33, causing the card block 33 to open in the front-back direction of the transformer top plate 2. When the protective cover 35 and the transformer top plate 2 are inserted completely, the gasket 36 will be in contact with the upper surface of the transformer top plate 2 to maintain the seal. At this time, release the positioning ring 31, and the reaction force of the card block 33 will push the positioning ring 31 upward. The upward moving positioning ring 31 will squeeze the arc surface on the other side of the card block 33, causing the card block 33 to move toward the middle of the transformer top plate 2. The card block 33 will be inserted into the card slot 302 to limit the position of the protective cover 35 to ensure the stability of the device. When it is necessary to disassemble the protective cover 35, move the positioning ring 31 downward to release the blockage of the card block 33, and then pull the protective cover 35 upward. The upward moving protective cover 35 will squeeze the arc surface of the card block 33 to disengage the card block 33 from the card slot 302 to release the limit.
[0038] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
