[0001] The invention relates to the technical field of switches for power distribution cabinet transformers, and in particular to a moisture-proof switch for outdoor environmentally friendly power distribution cabinet transformers. Background Art

[0002] In the patent application with application publication number CN101807474B, it includes a cover, a shell, and a rotor sandwiched between the cover and the shell. The rotor extends from the top of the transformer switch to the inner surface of the cover in the shell channel, and the cover includes a base member and a wall member extending from the base member. The wall member defines the internal space of the cover. For example, the wall member can extend substantially vertically from the base member. The advantage is that each movable contact is configured to be selectively electrically connected to at least one fixed contact. In some typical embodiments, each fixed contact-moving contact pair corresponds to a different electrical structure of the transformer winding, thereby generating different transformer voltages.

[0003] In the prior art including the above-mentioned patents and the use of distribution cabinet transformer switches in actual use, outdoor distribution cabinet transformer switches are exposed to the outside for a long time. When encountering rainy, snowy and humid weather, the plastic button of the switch and the inner wall of the press and slide will rust, and the dust and rainwater will mix and solidify. If not handled for a long time, the switch button will be stuck and affect normal pressing and use. In an emergency, the button cannot be pressed, which will affect the operating efficiency. Summary of the invention

[0004] The problem to be solved by the present invention is that when a transformer switch of a power distribution cabinet is used in an outdoor environment, it is easy for the pressing part to rust due to humidity, thereby affecting the use.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a moisture-proof switch for an outdoor environmentally friendly distribution cabinet transformer, comprising a cabinet plate, a switch terminal is penetrated on one side of the cabinet plate, a button is provided on one side of the switch terminal, a rotating shaft is provided on one side of the top of the cabinet plate, a shell is rotatably provided on one side of the rotating shaft, a threaded groove is provided on one side of the inner wall of the shell, and a moisture-proof structure is provided inside the shell;

[0006] The moisture-proof structure comprises a rubber sheet, a connecting sheet is provided on one side of the rubber sheet, a fixing ring is provided inside the shell, a plurality of protrusions are provided on the inner wall of the fixing ring in a circumferential array, a threaded tooth is provided on the outside of the fixing ring, the threaded tooth is matched with the threaded groove, and the fixing ring can fix the connecting sheet by threaded engagement, a pressing block is provided on one side of the rubber sheet, a connecting block is provided on the other side of the rubber sheet, and the rubber sheet can be deformed after being subjected to force, a placement box is provided on the rear side of the inner wall of the shell, a moisture-absorbing desiccant is provided inside the placement box, a plurality of adsorption holes are opened on the inner wall of the placement box, a plurality of heat-conducting rods are penetrated through one side of the placement box in a circumferential array, and the heat-conducting rods are provided on the inner wall of the placement box. A heat conducting plate is provided on one side of the heat rod, and the other side of the heat conducting plate is in contact with the surface of the cabinet panel. A plurality of guide grooves are provided on the top of the shell, a guide column is fixedly provided on one side of the bottom of the shell, a sealing ring is fixedly provided on one side of the shell, an insertion block is provided at the bottom of the cabinet panel, a storage groove is provided on one side of the bottom of the insertion block, a telescopic block is provided at the bottom of the storage groove, a return spring is provided inside the telescopic block, a shell is provided at the bottom of the shell, a slot is provided on one side of the shell, the slot is matched with the insertion block, a reset spring is fixedly provided on the top of one side of the inner wall of the shell, a spring block is fixedly provided on one side of the reset spring, and one side of the spring block passes through the shell and extends to the outside of the shell.

[0007] Preferably, a limit spring is fixedly provided on one side of the bottom of the shell, and an extrusion block is fixedly provided on the bottom of the limit spring.

[0008] Preferably, the top of the extrusion block passes through the shell and extends to the inside of the shell, and the extrusion block is used in conjunction with the telescopic block.

[0009] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0010] (1) The inside of the shell is provided with a moisture-proof structure. The shell itself is a kind of protective equipment. When used together with the switch, it can play the role of the outermost layer of protection. The rubber sheet on the moisture-proof structure can be used with the shell to control the button by pressing without opening the shell, so as to avoid the shell being opened and closed many times and affecting the dry environment inside. The rubber sheet is also set to be replaceable. When it is used for a long time in the outdoor environment and its elasticity becomes weak and it is inconvenient to press, the rubber sheet can be quickly removed by rotating and loosening the fixing ring. The moisture-proof structure is also provided with a placement box. The inside of the placement box is provided with a desiccant that absorbs moisture. When the power distribution cabinet and the transformer are started, heat will be generated. The heat of the cabinet will be transferred to the heat conducting rod by the heat conducting sheet. The desiccant can be dried by utilizing the residual heat so that it can be used repeatedly, so that the switch is always in a dry environment even outdoors to avoid rusting;

[0011] (2) A guide groove is provided on the top of the shell. When it rains, the guide groove can allow rainwater to flow down quickly from the top of the shell to avoid staying for a long time and affecting the sealing of the shell. A guide column is provided at the bottom of the shell to allow rainwater on its surface to fall quickly along the guide column. A sealing ring is provided at the closing point between the shell and the cabinet panel. The sealing ring can further keep the switch in a dry environment and will not be affected by the external environment. When the button needs to be maintained and the shell needs to be opened, the shell can be opened and closed by pressing the squeezing block. After the squeezing block is subjected to force, it will drive the shell to pop up through the spring block, allowing the user to quickly open the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The moisture-proof structure 6 includes a rubber sheet 601, a connecting sheet 608 is provided on one side of the rubber sheet 601, a fixing ring 605 is provided inside the housing 5, and a plurality of protrusions 607 are provided on the inner wall of the fixing ring 605 in a circular array, and a threaded tooth is provided on the outside of the fixing ring 605, and the threaded tooth is adapted to the threaded groove, and the fixing ring 605 can fix the connecting sheet 608 by threaded engagement, a pressing block 602 is provided on one side of the rubber sheet 601, and a connecting block 606 is provided on the other side of the rubber sheet 601, and the rubber sheet 601 can be deformed after being subjected to force, and a placement box 604 is provided on the rear side of the inner wall of the housing 5, and a moisture-absorbing desiccant is provided inside the placement box 604, and a plurality of adsorption holes are opened on the inner wall of the placement box 604, and a plurality of protrusions 607 are provided on one side of the placement box 604 in a circular array. A heat conducting rod 609 is provided on one side of the heat conducting rod 609, and a heat conducting sheet 603 is provided on the other side of the heat conducting sheet 603, and the surface of the cabinet panel 3 is fitted together. A plurality of guide grooves 4 are provided on the top of the shell 5, and a guide column 7 is fixedly provided on one side of the bottom of the shell 5, and a sealing ring is fixedly provided on one side of the shell 5. An insert block 10 is provided on the bottom of the cabinet panel 3, and a storage groove is provided on one side of the bottom of the insert block 10, and a telescopic block 12 is provided on the bottom of the storage groove, and a return spring is provided inside the telescopic block 12. A shell 8 is provided on the bottom of the shell 5, and a slot is provided on one side of the shell 8, and the slot is adapted to the insert block 10. A reset spring 11 is fixedly provided on the top of one side of the inner wall of the shell 8, and a spring block 14 is fixedly provided on one side of the reset spring 11, and one side of the spring block 14 passes through the shell 8 and extends to the outside of the shell 8.

[0029] A limit spring 15 is fixedly provided on one side of the bottom of the housing 8 , and an extrusion block 13 is fixedly provided on the bottom of the limit spring 15 .

[0030] The top of the extrusion block 13 passes through the housing 8 and extends to the inside of the housing 8 . The extrusion block 13 is used in conjunction with the telescopic block 12 .

[0031] The working principle and use process of the present invention are as follows: when the user needs to press the button 9, he can directly use his finger to align the pressing block 602 and press hard. After the pressing block 602 is subjected to force, the rubber sheet 601 will be deformed and the connecting block 606 will be driven to move backward through its own elastic force. After the connecting block 606 moves, it will contact the button 9 and move it to complete the pressing operation. When the shell 5 is closed, the button 9 can be kept in a sealed and dry state through the sealing ring. When the air is relatively humid and has a certain impact on the inside of the shell 5, the placement box 604 in the shell 5 will absorb the moisture through the internal desiccant to ensure the dryness of the inside of the shell 5. While absorbing moisture, the transformer of the distribution cabinet will generate heat inside because it is always in use. The heat will be absorbed by the heat conductive sheet 603 and conducted to the heat conductive rod 609. The heat conductive rod 609 can heat and dry the desiccant inside the placement box 604 so that it can be recycled and reused. When the elasticity of the rubber sheet 601 is affected after long-term use and needs to be replaced, the shell 5 can be opened. When opening the shell 5, the extrusion block 13 is pressed. The extrusion block 13 moves upward to compress the limit spring 15 while squeezing the telescopic block 12 into the storage groove. After the telescopic block 12 on the plug block 10 shrinks back, it will become a straight plate shape and lose the clamping connection with the shell 8. At this time, the elastic block 14 will drive the shell 5 to bounce outward through the resilience of the reset spring 11, and the user can then rotate the shell 5 with the rotation connection with the rotating shaft 1 as the center to open it. After opening, the fixing ring 605 can be rotated and removed by cooperating with the fingers and the protrusion 607. After removal, the rubber sheet 601 can be removed from the shell 5 and then replaced with a new rubber sheet 601, and then the fixing ring 605 can be rotated again to fix the connecting piece 608 through the meshing of the thread groove and the thread teeth. Close the shell 5 and directly press it down to allow the plug block 10 to fix the shell 8 again.
