The interior of the housing 1 is coaxially provided with a first annular groove 8 and a second annular groove 9. The push rod 2 is arranged in the first annular groove 8 and one end can extend out of the housing 1. The sealing gasket 4 is arranged in the first annular groove 8. The other end of the push rod 2 is provided with a connecting portion 19, which extends out of the sealing gasket 4. A pressure block 7 is arranged in the second annular groove 9. The pressure block 7 is connected to the connecting portion 19 through the connecting member 5. One end of the pressure block 7 abuts against the sealing gasket 4. The other end of the pressure block 7 is provided with a button sheet 6. The spring 3 is arranged on the periphery of the sealing gasket 4, and one end of the spring 3 abuts against the sealing gasket 4, and the other end of the spring 3 contacts the pressure block 7. See Figure 2 As shown, the first annular groove 8 is close to one end of the shell 1, the second annular groove 9 is close to the other end of the shell 1, and the first annular groove 8 and the second annular groove 9 are coaxially arranged and connected to each other. A circular hole connected to the first annular groove 8 is provided at one end of the shell 1, so that one end of the push rod 2 can pass through the circular hole and extend out of the shell 1. One end of the push rod 2 is used to contact the switch or button of the electrical control box to control the opening and closing of the corresponding switch or button.

[0024] The spring 3 is used to push the pressure block 7 and the push rod 2 to reset, and one end of the spring 3 can squeeze the sealing gasket 4 to facilitate the seal between the sealing gasket 4 and the inner wall of the housing 1. After the pressure block 7 is connected to the push rod 2 through the connecting member 5 (bolt), one end of the pressure block 7 can squeeze the sealing gasket 4 to achieve a seal between the sealing gasket 4 and the push rod 2, preventing water droplets from entering the push rod 2. The longitudinal section of the sealing gasket 4 is generally arched.

[0025] Furthermore, as a preferred embodiment, the outer edge of one end of the sealing gasket 4 is bent outward to form a bent portion 10, and a through hole is opened in the middle of the other end of the sealing gasket 4, and the connecting portion 19 passes through the through hole. Figure 2 As shown, the connecting portion 19 is block-shaped and is sealed with the through hole. The bent portion 10 of the sealing gasket 4 is integrally formed with the sealing gasket 4.

[0026] Furthermore, as a preferred embodiment, a sealing pressure ring 11 is further included. The upper surface of the bent portion 10 is provided with the sealing pressure ring 11, and one end of the spring 3 is abutted against the bent portion 10 through the sealing pressure ring 11. The sealing pressure ring 11 can play a sealing role, and cooperates with the arrangement of the spring 3 so that the sealing pressure ring 11 can press the bent portion 10 of the sealing gasket 4. At this time, the sealing pressure ring 11 and the bent portion are deformed, which can improve the sealing effect.

[0027] Furthermore, as a preferred embodiment, a first mounting groove 12 is provided at one end of the pressing block 7, a second mounting groove 13 is provided at the other end of the pressing block 7, the connecting portion 19 extends into the first mounting groove 12, and the button piece 6 is provided in the second mounting groove 13. Figure 2 As shown, the first mounting groove 12 and the second mounting groove 13 are connected to each other, and a threaded hole is opened at the other end of the push rod 2 for threaded cooperation with the connecting member 5, and the threaded hole passes through the connecting plate and extends to the inside of the push rod 2.

[0028] Furthermore, as a preferred embodiment, a first sealing ring 14 is further included, and a first sealing ring 14 is provided between one end of the pressing block 7 and the sealing gasket 4. The provision of the first sealing ring 14 facilitates improving the sealing between the pressing block 7 and the sealing gasket 4.

[0029] Furthermore, as a preferred embodiment, a second sealing ring 16 is further included. A limiting portion 15 is provided on the outer edge of the housing 1, and a second sealing ring 16 is provided on the limiting portion 15. Figure 2 As shown, the second sealing ring 16 is used to press against the external electrical control box to facilitate sealing between the housing and the external electrical control box.

[0030] Furthermore, as a preferred embodiment, a clamping portion 17 is further included. Two clamping portions 17 are provided on both sides of one end of the housing 1, and each clamping portion 17 is provided with a clamping block 18. A notch is provided on the outer wall of the clamping portion 17, and the clamping block 18 is disposed in the notch to cooperate with the clamping slot in the electrical control box, thereby facilitating the installation of the button on the electrical control box.

[0031] When in use, by pressing the button piece 6, the button piece 6 pushes the pressure block 7. At this time, the pressure block 7 pushes the push rod 2 to move, and at the same time compresses the spring 3. The movement of the push rod 2 will press the corresponding switch or button in the electrical control box to achieve opening or closing. Then, after releasing the button piece 6, under the action of the spring 3, the pressure block 7 drives the button piece 6 and the push rod 2 to automatically reset.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
