Description

Technical Field

[0001] This utility model relates to a flat button, and more particularly to a flat button that is easy to install and disassemble. Background Technology

[0002] A flat button is a common control switch in the field of electrical control. It usually includes a base, a pressing element, and a return spring. The pressing element is slidably mounted on the base, and the return spring is compressed between the base and the pressing element. This allows the pressing element to slide by pressing. The pressing element and the external linkage structure are linked to generate the electrical signal required by the flat button for the control circuit. However, the existing pressing element and base are inconvenient to install and disassemble, and the structural design is unreasonable. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flat button that is easy to install and disassemble, and has a simple and reasonable structural design.

[0004] The technical solution adopted by this utility model to solve its technical problem is a flat button that is easy to install and disassemble, including a base, a pressing member, an elastic member, and a rubber cover. The base is provided with a first cavity and a second cavity. The first cavity is located at the top, and the second cavity is located below the first cavity and the two are connected. The first cavity is used to cooperate with the upper end of the pressing member, and the second cavity is used to cooperate with the middle end of the pressing member. A first protruding ring is provided on the outer peripheral wall of the middle end of the pressing member. The first protruding ring and the second cavity are in clearance fit. A second protruding ring is provided at the bottom of the inner wall of the second cavity. The elastic member is connected between the first protruding ring and the second protruding ring. The lower end of the pressing member is provided with circumferentially spaced elastic hooks. The hook part of the elastic hook is located below the second protruding ring. A locking and fixing structure is provided between the rubber cover and the upper end of the pressing member.

[0005] The advantages of the above technical solution are as follows: The design of the first and second cavities enables the base to protect the pressing component, improving the protective and safety performance of the device. The first convex ring prevents the pressing component from shaking significantly when sliding up and down, resulting in better device performance. It also limits the position of the top of the elastic component. The second convex ring limits the position of the bottom of the elastic component. The reasonable placement of the first and second convex rings facilitates the installation of the elastic component. The elastic hook secures the pressing component to the base. The elastic hook allows for easy deformation, facilitating installation and disassembly. The rubber cover protects the upper end of the pressing component, further enhancing the protective and safety performance of the device. The rubber cover is installed on the upper end of the pressing component through a snap-fit ​​structure, which, compared to threaded or pressure-covered fixing methods, provides a more secure connection and reduces the number of components. Therefore, this device features convenient installation and disassembly, a simple and reasonable structural design, and excellent protective and safety performance.

[0006] Furthermore, the flat button also includes a first sealing element and a second sealing element, the first sealing element being installed on the outer peripheral wall surface of the first convex ring, and the second sealing element being installed on the outer peripheral wall surface of the base.

[0007] The advantages of adopting the above technical solution are as follows: by setting the first sealing element, dust and moisture can be prevented from entering the switch from the second cavity of the base, and by setting the second sealing element, dust and moisture can be prevented from entering the switch from the outer peripheral wall of the base, thus achieving the purpose of dust and water resistance and making it safer to use.

[0008] Furthermore, a sealing ring groove is provided on the outer peripheral wall surface of the first convex ring, and the first sealing element is fitted into the sealing ring groove.

[0009] The advantages of adopting the above technical solution are: by setting the sealing ring groove, the installation position of the first sealing element is well defined, resulting in a better performance of the first sealing element.

[0010] Furthermore, the first sealing element includes a sealing ring and an elastic sealing skirt, the sealing skirt being disposed on the outer peripheral wall surface of the sealing ring and facing the rubber cover.

[0011] The advantages of adopting the above technical solution are as follows: The first sealing element adopts the structure of a sealing ring and a sealing skirt. The sealing ring achieves a tight connection with the sealing ring groove, and the sealing skirt achieves an elastic tight connection with the second cavity. Therefore, the first sealing element will have a better performance and a better sealing effect.

[0012] Furthermore, adjacent elastic hooks are spaced to form a limiting groove, and a corresponding limiting block is provided on the lower wall surface of the second convex ring. The limiting block cooperates with the limiting groove to restrict the pressing member to move only along the axial direction.

[0013] The advantages of adopting the above technical solution are: by cooperating with the limiting groove and the limiting block, the pressing part can only move axially and will not rotate circumferentially, making the action more reliable. In addition, the forming method of the limiting groove is also reasonable and effectively utilizes the elastic hook.

[0014] Furthermore, a third protruding ring is provided at the bottom of the first cavity, and the third protruding ring is positioned directly below the upper end of the pressing member.

[0015] The advantages of adopting the above technical solution are as follows: The setting of the third convex ring can, on the one hand, limit the upper bottom of the pressing part, thereby effectively preventing excessive pressing of the pressing part; on the other hand, it can protect the top opening of the second cavity, thereby preventing the intrusion of dust and moisture, resulting in better protection and safer use.

[0016] Furthermore, the upper peripheral wall of the pressing member is provided with a first protrusion and a fourth protruding ring, the fourth protruding ring being disposed below the first protrusion. The inner peripheral wall of the rubber cover is provided with a second protrusion and a fifth protruding ring, the second protrusion being disposed corresponding to the first protrusion, the second protrusion being provided with a slot, the corresponding first protrusion engaging with the slot, the fifth protruding ring being disposed below the second protrusion, the fifth protruding ring engaging with the fourth protruding ring.

[0017] The advantages of the above technical solution are: through the snap-fit ​​engagement of the first protrusion and the second protrusion, and the snap-fit ​​engagement of the fourth protrusion and the fifth protrusion, the double snap-fit ​​fixation of the pressing part and the rubber cover is achieved, making the connection between the pressing part and the rubber cover more stable and the performance better.

[0018] Furthermore, the pressing part of the rubber cover has a concave arc-shaped structure, and a pressing cavity is provided on the upper end face of the pressing member, which is positioned directly below the pressing part.

[0019] The advantages of adopting the above technical solution are: the combination of the arc-shaped pressing part and the pressing cavity makes the force more concentrated on the pressing part, resulting in better performance. Attached Figure Description
