Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a waterproof switch. Background Technology

[0002] A switch is a device used to control the on / off state of a circuit, widely used in various electrical equipment and systems. The main function of a switch is to control the flow of current, thereby controlling the start and stop of equipment. In some cases, switches can also be used to protect circuits and equipment from overload or short circuits. Types of switches include: mechanical switches: which control the flow of current through physical contact, such as push-button switches, toggle switches, and rotary switches; electronic switches: which use semiconductor devices to control current, such as relays and solid-state relays; and smart switches: which combine electronic and communication technologies and can be remotely controlled wirelessly or via wired connections, such as smart switches in smart homes.

[0003] Most existing switches have a button plate and cover plate directly mounted on the switch component body. However, gaps exist between the button plate and cover plate. In environments with frequent water and steam, or when hands are wet and the switch is in contact with water, moisture can easily enter the cover plate through these gaps, causing short circuits or damage to the internal components of the switch. Therefore, those skilled in the art have provided a waterproof switch to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof switch. This switch achieves a sealing and barrier function by setting a waterproof shell between the switch button body and the keypad, and the internal sponge ring absorbs water, preventing water from entering the switch through the gap between the keypad and the cover plate and damaging the internal components.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A waterproof switch includes a switch element body, a mounting bracket, and a cover plate. A switch button body is disposed at the middle of the front side of the switch element body. A waterproof shell is fixedly disposed inside the front side of the mounting bracket. Two through holes are opened at the middle of the front end of the waterproof shell. Telescopic sleeves are fixedly disposed at the two through holes on the inner wall of the rear side of the waterproof shell. A sponge ring is movably sleeved around the waterproof shell. A first through groove is opened at the middle of the front end of the cover plate. A button plate is rotatably disposed inside the first through groove. Connecting posts are hinged to the upper and lower sides of the rear end of the button plate.

[0007] Furthermore, the mounting bracket has slots at both ends near the sides, and the cover plate has blocks fixedly installed on both sides of its inner walls.

[0008] Furthermore, the two connecting posts extend into the interior of the two telescopic sleeves respectively, and the rear ends of the two connecting posts are fixedly connected to the inner front walls of the two telescopic sleeves respectively.

[0009] Furthermore, a second through groove is provided in the middle of the inner wall of the rear side of the mounting bracket, and the second through groove and the switch element body are fixedly sleeved together.

[0010] Furthermore, the waterproof shell is made of plastic, and both of the telescopic sleeves are made of silicone.

[0011] Furthermore, the two telescopic sleeves are respectively aligned with the upper and lower sides of the switch button body.

[0012] This utility model has the following beneficial effects:

[0013] This utility model proposes a waterproof switch. The switch features a waterproof shell on the front of the switch button body, sealing both the switch element body and the switch button body. When the switch is activated, the button plate on the cover is pressed. Two connecting posts are hinged to the rear of the button plate, penetrating into the telescopic sleeve and fixedly connected to its rear inner wall. Pressing the button plate lowers the upper or lower side, causing the connecting posts on the upper or lower side to push the telescopic sleeve backward, thus pushing the upper or lower side of the switch button body. This achieves switch control. Simultaneously, the waterproof shell between the button plate and the switch button body provides a sealing barrier. Furthermore, an internal sponge ring absorbs water, preventing water from entering the switch through the gap between the button plate and the cover plate and damaging the internal components. Therefore, this switch exhibits excellent waterproof performance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-6 One embodiment provided by this utility model:

[0024] A waterproof switch includes a switch element body 1, a mounting bracket 3, and a cover plate 4. A switch button body 2 is provided at the middle of the front side of the switch element body 1. A waterproof shell 6 is fixedly provided inside the front side of the mounting bracket 3. Two through holes 14 are opened at the middle of the front end of the waterproof shell 6. A telescopic sleeve 8 is fixedly provided at the two through holes 14 on the inner wall of the rear side of the waterproof shell 6. A sponge ring 7 is movably fitted around the waterproof shell 6. A first through groove 12 is opened at the middle of the front end of the cover plate 4. A button plate 5 is rotatably provided inside the first through groove 12. Connecting posts 9 are hinged at the upper and lower sides of the rear end of the button plate 5.

[0025] The mounting bracket 3 has slots 10 at both ends near the sides. The cover plate 4 has blocks 11 fixedly installed on the inner walls near the sides. The two connecting posts 9 pass through the two telescopic sleeves 8 respectively. The rear ends of the two connecting posts 9 are fixedly connected to the inner walls of the front sides of the two telescopic sleeves 8 respectively. The mounting bracket 3 has a second through groove 13 in the middle of the inner wall of the rear side. The second through groove 13 is fixedly fitted with the switch element body 1. The waterproof shell 6 is made of plastic. The two telescopic sleeves 8 are made of silicone. The two telescopic sleeves 8 are aligned with the upper and lower sides of the switch button body 2 respectively.

[0026] Specifically, a waterproof shell 6 is installed between the switch button body 2 and the button plate 5 to prevent water from entering the interior through the gap between the button plate 5 and the cover plate 4 and damaging the internal components of the switch. Two through holes 14 are opened and a telescopic sleeve 8 is installed. The connecting post 9 passes through the telescopic sleeve 8, which allows the operation of the button plate 5 to be transmitted to the switch button body 2. The mounting bracket 3 has slots 10 on the upper and lower sides, and the cover plate 4 has blocks 11 fixed on the upper and lower sides. The cover plate 4 and the mounting bracket 3 are locked together by the blocks 11 and the slots 10, and the cover plate 4 can be removed from the mounting bracket 3. A sponge ring 7 is installed between the mounting bracket 3 and the cover plate 4 to absorb water and prevent water from accumulating inside. The cover plate 4 can be removed from the mounting bracket 3 and the sponge ring 7 can be replaced. The connecting post 9 is hinged to the rear side of the button plate 5. When the button plate 5 is pressed, the connecting post 9 and the button plate 5 can be adjusted at a certain angle so that the connecting post 9 can be kept inside the telescopic sleeve 8.

[0027] The switch element body 1 and the switch button body 2 operate on the same principle as existing switches. The basic function of a switch is to control the opening and closing of a circuit, that is, to allow current to pass through in the closed state and to block current from passing through in the open state. The switch controls the opening or closing of the device by changing the opening and closing state of the circuit. The switch element body 1 has contacts, usually composed of two or more metal contact points. In the closed state, the contacts are in contact to form a conductive path. In the open state, the contacts are separated to cut off the current. By tossing the switch button body 2, the contacts are moved from one position to another, thereby changing the opening and closing state of the circuit.

[0028] Working principle: When using this switch, after installation, pressing the switch button 5 causes the upper side of the button 5 to be pushed up, and the upper connecting post 9 to be pushed backward. At the same time as the connecting post 9 is pushed backward, the telescopic sleeve 8 is extended, which pushes the upper side of the switch button body 2 to control the switch. When pressing the lower side of the button 5, the upper side of the button 5 is pushed up, and the lower side is pushed, which pushes the lower connecting post 9. At the same time as the upper side of the button 5 is pushed up, the upper connecting post 9 moves forward, which shortens the telescopic sleeve 8, and the lower connecting post 9 pushes the lower side of the switch button body 2. The movement of the switch button body 2 causes the contacts inside the switch element body 1 to make or separate, so that the internal circuit is connected or disconnected, thereby realizing the control of the switch.

[0029] Secondly, a waterproof shell 6 is provided between the switch button body 2 and the button plate 5. The waterproof shell 6 and the two telescopic sleeves 8 can play a sealing role to prevent water from entering the switch element body 1 and damaging the internal components. In addition, a sponge ring 7 is provided between the waterproof shell 6 and the cover plate 4 to absorb water.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
