All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses a waterproof device for a transformer switch, comprising a connecting cylinder 1, a groove 2 on the outer side of the connecting cylinder 1, a rubber ring 3 inside the groove 2, a mounting ring 4 outside the rubber ring 3, a mounting cylinder 5 outside the mounting ring 4, a sealing cover 6 on one side of the mounting cylinder 5, a fin 7 on the outer side of the sealing cover 6, a retaining plate 8 inside the connecting cylinder 1, a mounting bracket 9 on one side of the retaining plate 8, a guide rod 10 inside the mounting bracket 9, a support spring 11 and a guide block 12 on the outer side of the guide rod 10, a support rod 13 on the outer side of the guide block 12, and a mounting post 14 on the inner side of the sealing cover 6. In this embodiment, the connecting cylinder 1 serves to protect the switch, the groove 2 serves to limit movement, and the rubber ring 3 serves to seal.
[0029] Reference Figure 1 The rubber ring 3 is adapted to the groove 2, and the rubber ring 3 is snapped into the inside of the mounting ring 4. The mounting ring 4 is fixedly connected to the inside of the mounting cylinder 5. In this embodiment, the mounting ring 4 plays a limiting role, and the mounting cylinder 5 plays a transmission role.
[0030] Reference Figure 1 The mounting ring 4 is slidably connected to the outside of the connecting cylinder 1, the sealing cover 6 is fixedly connected to the mounting cylinder 5, and the fin 7 is fixedly connected to the outside of the sealing cover 6. In this embodiment, the sealing cover 6 serves to seal the mounting cylinder 5, and the fin 7 serves to facilitate the flow of rainwater.
[0031] Reference Figure 2 and Figure 3 The mounting column 14 is provided with a mounting bracket 9 inside. The guide rod 10 is fixedly connected to the inside of the mounting bracket 9. The guide block 12 is slidably connected to the outside of the guide rod 10. In this embodiment, the mounting column 14 plays a limiting role, the mounting bracket 9 plays a role in fixing the guide rod 10, and the guide rod 10 plays a role in restricting the movement path of the guide block 12.
[0032] Reference Figure 1 and Figure 3 The support spring 11 is movably connected to the outside of the guide rod 10, and the two ends of the support rod 13 are rotatably connected to the outside of the guide block 12. The clamping plate 8 is clamped inside the connecting cylinder 1. The support rods 13 are cross-connected to each other. In this embodiment, the guide block 12 plays a transmission role, and the clamping plate 8 plays a role in fixing the mounting cylinder 5.
[0033] The implementation principle of this embodiment is as follows:
[0034] First, install the connecting cylinder 1 on the outside of the transformer switch and ensure that the connection is completely sealed. Then, push the mounting cylinder 5 to slide on the outside of the connecting cylinder 1. During the movement of the mounting cylinder 5, it will push the mounting ring 4 to move. The mounting ring 4 will push the rubber ring 3 on the outside of the connecting cylinder 1. Since the minimum inner diameter of the rubber ring 3 is smaller than the outer diameter of the connecting cylinder 1, the rubber ring 3 will be squeezed and deformed during the movement of the rubber ring 3 on the outside of the connecting cylinder 1 until the rubber ring 3 moves to the groove 2. At this time, the rubber ring 3 will return to its phase change and completely fill the inside of the groove 2, which will play a sealing role and effectively prevent rainwater from entering.
[0035] When the mounting cylinder 5 slides outside the connecting cylinder 1, one side of the clamping plate 8 is set as an inclined surface, which facilitates the clamping plate 8 to be clamped into the interior of the connecting cylinder 1. When the position of the clamping plate 8 changes, the guide block 12 will slide outside the guide rod 10, and both ends of the support rod 13 will rotate outside the guide block 12, so that the support rod 13 can change its angle. After the clamping plate 8 is completely inserted into the interior of the connecting cylinder 1, under the action of the support rod 13, the guide block 12 will pull the support spring 11 to deform. The pull generated by the deformation of the support spring 11, combined with the support rod 13, can provide sufficient thrust for the clamping plate 8. Even if pulled manually, a large force is required, which can prevent the mounting cylinder 5 from loosening during the sealing process, thereby ensuring complete isolation from rainwater.
[0036] Compared with the prior art, the present invention has the following advantages:
[0037] The connection tube 1 and the mounting tube 5 work together to protect the switch. The groove 2, rubber ring 3 and mounting ring 4 work together to provide waterproofing. The sealing cover 6 and fin 7 work together to facilitate rainwater flow. By using the above structure, the sealing performance of the switch is improved, which can effectively prevent rainwater from contacting the switch and thus eliminate the safety hazards caused by rainwater conduction. The support rod 13, mounting bracket 9 and guide block 12 work together to push the card plate 8 to fit against the connection tube 1. The guide block 12 and guide rod 10 work together to provide a limiting function. The addition of the mounting bracket 9 fixes the guide rod 10. By using the above structure, the mounting tube 5 and the connection tube 1 can be installed more firmly.
[0038] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
