DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 6The utility model provides a technical solution: a large current waterproof rocker switch, including a rocker switch housing 1, a pin 4 installed at the bottom of the rocker switch housing 1, a convex edge 17 set at the top edge of the rocker switch housing 1, a button 2 installed in the middle of the top of the rocker switch housing 1, the size of the button 2 is larger than the size of the groove 11, so that the button 2 can play a certain role in blocking water in the groove 11, and a sealing member 5 installed on the outside of the button 2 and the convex edge 17. The structure inside the rocker switch housing 1 is the existing technology, so it will not be described in detail. The pin 4 is The thickened design can withstand a larger current. The seal 5 includes a fixed portion 51 and a corrugated portion 52. The fixed portion 51 is sleeved on the outer side of the convex edge 17 to fix the seal 5 on the rocker switch housing 1. The corrugated portion 52 can deform with the action of the button 2, so that when the button 2 is in action, there is no gap between the button 2 and the fixed portion 51 to ensure a reliable seal. The fixed portion 51 and the corrugated portion 52 are an integrally formed structure. The top of the fixed portion 51 is provided with a first opening 12. The first opening 12 is thickened to prevent deformation. The first opening 12 facilitates the fixation of the button 2 and the fixing portion 51. A first positioning frame 7 that matches the first opening 12 is provided on one side of the button 2. A plurality of buckles 9 are provided on the bottom of the first positioning frame 7. The buckles 9 are used to engage with the corrugated portion 52 to achieve the connection and fixation between the button 2 and the fixing portion 51. A sealing ring 10 is installed on the outside of the first positioning frame 7. A second positioning frame 8 is provided on one side of the button 2. The second positioning frame 8 fits with the groove 11 to play a first sealing role. The first positioning frame 7 fits with the first opening 12 to play a second sealing role. The sealing ring 10 fits together with the recessed portion 13 and the limiting groove 16 to play a third sealing role, thereby greatly improving the sealing between the button 2 and the fixed portion 51. Even if impacted by a large amount of water, there will be no water leakage. The top of the fixed portion 51 is provided with a groove 11 that cooperates with the second positioning frame 8. The inner wall of the groove 11 is penetrated by a plurality of downward-inclined drainage holes 6. The drainage holes 6 are used to drain water in the groove 11 to avoid water accumulation in the groove 11. The downward-inclined drainage holes 6 make it easier to drain water. The drainage holes 6 are connected to the groove 11.

[0020] Among them, a second opening 14 is opened at the bottom of the fixing part 51, and the second opening 14 facilitates the installation of the fixing part 51 to the outside of the flange 17. A sealing groove 15 is provided inside the fixing part 51 to match the flange 17. When the seal 5 is installed, the flange 17 fits with the sealing groove 15, thereby playing a sealing role.

[0021] Among them, a limiting groove 16 is provided on the outer side of the first positioning frame 7, and the limiting groove 16 is used to limit the sealing ring 10 to prevent the sealing ring 10 from moving outside the first positioning frame 7. The sealing ring 10 is installed at the limiting groove 16, and the inner side wall of the first opening 12 is provided with a recessed portion 13, and the recessed portion 13 makes the fixing portion 51 fit the sealing ring 10 more closely.

[0022] The sealing member 5 and the sealing ring 10 are both made of rubber. Rubber has excellent elasticity and can provide a good sealing effect. Rubber is also corrosion-resistant, which makes it have a long service life.

[0023] A serrated elastic member 3 is provided on the outer side of the rocker switch housing 1 , and the serrated elastic member 3 facilitates installation and fixation of the rocker switch housing 1 .

[0024] Specifically, when impacted by water flow, the button 2 will block part of the water, and part of the water will enter the groove 11 through the gap between the second positioning frame 8 and the fixed part 51 and the drainage hole 6. The water in the groove 11 will be blocked by the second positioning frame 8, and the water will be discharged out of the groove 11 along the drainage hole 6. Even if part of the water passes through the second positioning frame 8, it will be blocked by the first positioning frame 7 and the limiting groove 16 and cannot enter the interior of the corrugated part 52.
