[0025] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] The object of the present invention is to provide a waterproof boat-shaped switch, which is used to prevent a short circuit from occurring inside a housing due to water flowing into the housing.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1 This embodiment provides a waterproof boat-shaped switch, including a housing 1, a button 2, a pin, a swing metal block 6, an elastic component and an insulating sealing layer 11.

[0029] The top of the housing 1 has an opening for placing the button 2, and the button 2 is rotatably connected to the side wall of the housing 1. The pin passes through the bottom of the housing 1 and is fixedly connected to the housing 1. The pins include a first pin 3, a second pin 4, and a third pin 5, which are distributed from left to right. The swing metal block 6 is located in the housing 1 and is rotatably connected to the side wall of the housing 1. When the left end of the swing metal block 6 is pressed down, it contacts the first pin 3 and the second pin 4 at the same time, and the first pin 3 is connected to the second pin 4. When the right end of the swing metal block 6 is pressed down, it contacts the second pin 4 and the third pin 5 at the same time, and the second pin 4 is connected to the third pin 5. The elastic component includes a fixed seat 7, a spring 8, a movable seat 9, and a roller 10. The fixed seat 7 is fixed to the bottom of the button 2, the first end of the spring 8 is fixedly connected to the fixed seat 7, and the second end of the spring 8 is fixedly connected to the movable seat 9. The roller 10 is rotatably mounted on the movable seat 9. The insulating sealing layer 11 is bonded inside the housing 1 and is located between the elastic component and the swinging metal block 6, so as to divide the internal space of the housing 1 into a top cavity and a bottom cavity which are not connected to each other. The roller 10 is in rolling contact with the top surface of the insulating sealing layer 11 and can deform the insulating sealing layer 11, so as to drive the left or right end of the swinging metal block 6 to press down when the button 2 drives the elastic component to swing.

[0030] The working principle of the waterproof boat switch is as follows: the button 2 has two working positions, namely, the left end is pressed and the right end is pressed. When the button 2 is in the left end pressed state, the roller 10 is located above the right end of the swing metal block 6, and the roller 10 indirectly presses down the right end of the swing metal block 6 through the insulating sealing layer 11, so that the second pin 4 is connected to the third pin 5. When the user presses down the right end of the button 2, the roller 10 rolls to the left on the insulating sealing layer 11 to the upper left end of the swing metal block 6, and indirectly presses down the left end of the swing metal block 6 through the insulating sealing layer 11, so that the first pin 3 is connected to the second pin 4. During the whole process, the spring 8 is in a compressed state to apply thrust to the roller 10. Since the insulating sealing layer 11 divides the internal space of the housing 1 into a top cavity and a bottom cavity that are not connected to each other, when water enters the housing 1 through the gap between the button 2 and the housing 1, it is blocked in the top cavity by the insulating sealing layer 11 and will not enter the bottom cavity, thereby avoiding a short circuit in the bottom cavity. Compared with the sliding contact mode, the roller 10 and the insulating sealing layer 11 are in rolling contact, which can prevent the insulating sealing layer 11 from being worn out and prevent the insulating sealing layer 11 from falling off the housing 1 due to excessive friction.

[0031] The material of the insulating sealing layer 11 can be of various types, and those skilled in the art can select according to actual needs. In this embodiment, the material of the insulating sealing layer 11 is rubber, and those skilled in the art can also select other materials such as nylon.

[0032] As a possible example, the elastic component further includes a guide pin 12. The spring 8 is sleeved on the outside of the guide pin 12, one end of the guide pin 12 is fixedly connected to the movable seat 9, and the other end of the guide pin 12 is in sliding contact with the corresponding guide hole on the fixed seat 7. Through the cooperation between the guide pin 12 and the guide hole, the direction of the spring 8 can be ensured to prevent the spring 8 from bending.

[0033] As a possible example, the waterproof boat switch further includes a water absorbing block 13, which is located between the button 2 and the insulating sealing layer 11 to absorb water drops above the insulating sealing layer 11. By absorbing moisture through the water absorbing block 13, the water retained on the insulating sealing layer 11 can be reduced.

[0034] There are many types of water absorbing blocks 13, and those skilled in the art can select according to actual needs. In this embodiment, the water absorbing block 13 is a water absorbing sponge, and those skilled in the art can also select other materials with good water absorption such as cotton.

[0035] As a possible example, the button 2 is rotatably connected to the side wall of the housing 1 through a bolt 14 and a nut. The bolt 14 passes through the button 2 and the side wall of the housing 1, and the nut is threadedly connected to the bolt 14. After the button 2 is removed from the housing 1, the water absorbing block 13 inside the housing 1 can be taken out and the water can be squeezed out, or the water absorbing block 13 can be replaced.

[0036] As a possible example, the front and rear sides of the swing metal block 6 are provided with a pin shaft, and the front inner wall and the rear inner wall of the housing 1 are provided with a groove 15 with an opening facing upward, and the pin shaft is located at the bottom of the groove 15 and is rotatably connected to the groove 15. When installing the swing metal block 6, the pin shaft is slid downward along the groove 15 to the bottom of the groove 15. Similarly, when disassembling the swing metal block 6, the pin shaft is slid upward out of the groove 15. The above structure makes it more convenient to install and disassemble the swing metal block 6.

[0037] As a possible example, the pins and the swing metal block 6 are both made of copper and are silver-plated.

[0038] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
