[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Please refer to Figures 1 to 5 , which is a highly sealed waterproof washer as the best embodiment of the present utility model, and is used for the sealing and waterproofing of toggle switches or push-button switches; it includes an annular sealing part 10 arranged on the outside, a movable part 20 located inside the annular sealing part 10 and capable of opening and closing following the toggle switch / push-button switch, and an annular connecting part 30 is arranged between the movable part 20 and the annular sealing part 10 to enable the movable part 20 to move inside the annular sealing part 10; the waterproof washer of the present utility model will cover the toggle switch / push-button switch and move following the toggle switch / push-button switch through the arranged movable part 20, and at the same time use the annular sealing part 10 to achieve a sealing effect. Therefore, by using the movable part 20 in cooperation with the annular sealing part 10, a waterproof washer with high reliability, high sealing performance and high waterproof level can be achieved. Moreover, the waterproof washer of the present utility model has low cost and is easy to manufacture.

[0030] The movable part 20 moves horizontally following the opening and closing of the toggle switch, or moves vertically following the opening and closing of the push switch. Specifically, outside the waterproof gasket of the present utility model, a key is further provided for driving the toggle arm to move or the button unit to move. The movable part 20 is arranged below the key. When the key drives the toggle arm or the button unit, the movable part 20 moves accordingly, and during the movement, it completely covers the toggle switch / push switch. At the same time, during the movement, the annular sealing part 10 does not move, so as to ensure the waterproof effect of the waterproof gasket.

[0031] The waterproof gasket is a rubber part; the annular sealing part 10, the annular connecting part 30 and the movable part 20 are of an integral structure and are integrally formed by a rubber mold.

[0032] For details, please refer to Figure 4 , an annular groove 11 is arranged at the bottom of the annular sealing part 10. By arranging the annular groove 11, the annular sealing part 10 can have a certain compression amount when being extruded, increasing the fitting area at the bottom of the annular sealing part 10 and achieving a good sealing and waterproof effect. At the same time, an annular step 12 is arranged at the top of the annular sealing part 10. When being extruded, the annular step 12 cooperates with the annular groove 11 to make the sealing effect of the upper and lower end faces of the annular sealing part 10 better.

[0033] For details, please refer to Figure 3 , the movable part 20 includes a covering part 21 for covering the main body part (the part excluding the toggle arm) below the toggle switch and a driven part 22 arranged above the covering part 21. The driven part 22 covers the toggle arm of the toggle switch; the inner side wall of the driven part 22 is as close as possible to the outer side wall of the toggle arm so that the key can drive the toggle arm better; for details, please refer to Figure 5 , when a push switch is adopted, the movable part 20 includes a covering part 21 for covering the push switch, and there is no need to set the driven part 22. Of course, this structure is also applicable to a touch switch that does not require a large stroke. Therefore, when there is a driven part 22, it is more suitable for a switch with a raised part above, such as a toggle switch. When there is no driven part 22, it is more suitable for a switch with a more square overall shape, such as a touch or push switch, etc.

[0034] A limiting step 40 for preventing its movement is arranged on the annular sealing part 10; the limiting step 40 is arranged as required. For example, it can be arranged on the outer side wall of the annular sealing part 10, and the annular sealing part 10, the annular connecting part 30, the movable part 20 and the limiting step 40 are of an integral structure.

[0035] For details, please refer to Figure 3The annular connecting portion 30 includes an annular horizontal portion 31 and an annular elastic portion 32 which is arranged on the inner side of the annular horizontal portion 31 and is in a U-shape. Specifically, the outer wall of the annular horizontal portion 31 is located on the inner wall of the annular sealing portion 10. One side of the annular elastic portion 32 is connected to the annular horizontal portion 31, and the other side is connected to the movable portion 20. The annular horizontal portion 31 is matched with the annular elastic portion 32 to provide the required moving stroke of the movable portion 20. In particular, when the waterproof gasket is matched with a toggle switch, a limiting step 40 is required to be provided to prevent the displacement of the annular sealing portion 10 and reduce the waterproof effect.

[0036] To summarize, the waterproof gasket of the utility model can cover the toggle switch / push switch and move with the toggle switch / push switch through the movable part, and at the same time, the annular sealing part is used to achieve a sealing effect. Therefore, the movable part is used in conjunction with the annular sealing part to achieve a waterproof gasket with high reliability, high sealing and high waterproof level. Furthermore, the waterproof gasket of the utility model is low-cost and easy to manufacture.

[0037] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
