Description

Technical Field

[0001] This utility model relates to the field of button sealing ring technology, specifically a button sealing ring. Background Technology

[0002] Button seals are sealing elements widely used in machinery, electronics, automotive, home appliances, aerospace, and other fields. Their core function is to form a reliable sealing interface between the button operating mechanism and the mounting base, effectively preventing impurities such as liquids, gases, and dust from entering the equipment, while also preventing leakage of internal media such as lubricating oil and coolant, ensuring the flexibility of button operation and the stability of equipment operation. In scenarios such as automotive central control buttons, industrial equipment control panels, home appliance control buttons, and aerospace cockpit control buttons, the sealing performance of button seals directly affects the service life and operational safety of the equipment.

[0003] Existing button seals have a relatively simple structural design, making it difficult for them to adapt to the deformation requirements during button pressing, and sealing gaps are likely to appear after long-term use. Summary of the Invention

[0004] The purpose of this invention is to provide a button sealing ring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a button sealing ring, including a main sealing part, a connecting hole at the bottom of the main sealing part, a plurality of annular grooves evenly formed in the connecting hole, the plurality of annular grooves being arranged longitudinally, an elastic support ring embedded in the annular grooves, a positioning guide part fixedly connected to the upper end face of the main sealing part, and a plurality of anti-rotation limiting parts fixedly connected to the lower end of the outer wall of the main sealing part, the plurality of anti-rotation limiting parts being arranged annularly along the outer wall of the main sealing part.

[0006] Preferably, the top surface of the positioning guide is fixedly connected with multiple anti-slip ridges.

[0007] Preferably, the main sealing part, positioning guide part, anti-rotation limiting part and anti-slip rib are integrally molded fluororubber structures.

[0008] Beneficial effects

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model embeds elastic support rings in multiple annular grooves in the main sealing part. The elastic support rings can provide continuous elastic force, effectively adapt to the deformation during the button pressing process, avoid the formation of sealing gaps after long-term use, reliably block the intrusion of impurities such as liquids, gases, and dust, and prevent leakage of internal media, thus significantly improving sealing reliability and service life.

[0011] 2. Meanwhile, the positioning guide on the upper surface of the main sealing part can play a precise guiding role during installation, helping to quickly position the sealing ring to the correct installation position and improve assembly efficiency; the multiple anti-slip ridges on the top of the positioning guide can increase the friction during installation, prevent slippage during assembly, and further improve the ease of installation.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Example 1

[0020] like Figure 1-2 This is a schematic diagram of the structure of a button sealing ring according to a preferred embodiment of the present invention. In this embodiment, a button sealing ring includes a main sealing part 1, a positioning guide part 3, an anti-rotation limiting part 4, and an anti-slip ridge 5, which are integrally formed from fluororubber material through a mold.

[0021] The main sealing part 1 is frustum-shaped, with a connecting hole 11 at the center of its bottom for accommodating the button lever. Multiple parallel annular grooves 12 are uniformly machined along the axial direction on the inner wall of the connecting hole 11. There are two annular grooves 12. An annular elastic support ring 2 is nested within each annular groove 12. This elastic support ring 2 is made of silicone material with elasticity superior to that of the fluororubber body, and is partially embedded in the groove while partially protruding outwards to contact the button lever.

[0022] The positioning guide 3 is integrally connected to the upper end face of the main sealing part 1. The positioning guide 3 is an annular flange with an outer diameter slightly smaller than the outer diameter of the upper end of the main sealing part 1, allowing it to be more easily inserted into the mounting hole during installation, thus providing initial positioning and guidance. Several radially distributed anti-slip ridges 5 are also integrally formed on the top plane of the positioning guide 3. These anti-slip ridges 5 are fine raised stripes that increase the friction between the installation tool or finger and the top of the sealing ring, preventing slippage during pressing and installation.

[0023] In this embodiment, a plurality of anti-rotation limiting parts 4 are integrally connected to the lower end of the outer wall of the main sealing part 1. There are six anti-rotation limiting parts 4, arranged uniformly in a circular pattern along the circumference. Each anti-rotation limiting part 4 is a convex wedge-shaped block structure. When the sealing ring is pressed into the mounting hole of the device, these anti-rotation limiting parts 4 undergo elastic deformation to pass through the opening, and then return to their original shape, locking into the bottom of the mounting hole or a groove of a specific structure. This prevents the sealing ring from rotating circumferentially due to repeated button rotation during use, and also provides axial limiting, preventing it from coming out of the mounting hole.

[0024] The sealing ring is fitted onto the button's stem through a connecting hole 11 at its bottom. When the button is pressed, the button stem compresses multiple elastic support rings 2 on the inner wall of the connecting hole 11. These support rings 2 provide uniform and sufficient elastic deformation and restoring force, ensuring that the sealing ring always fits tightly against the button stem, adapting to deformation during the pressing stroke, maintaining a dynamic sealing effect, and effectively preventing media leakage and contaminant intrusion. The anti-rotation limiting part 4 ensures the stability of the sealing ring body, while the positioning guide part 3 and the anti-slip ridge 5 make the installation process faster and more accurate.

[0025] Example 2

[0026] This embodiment has the same basic structure as Embodiment 1, the main difference being the choice of material for the elastic support ring 2. In this embodiment, the elastic support ring 2 is made of polyurethane (PU). Polyurethane has excellent wear resistance, high elasticity, and mechanical strength, providing stronger support and a longer service life, making it particularly suitable for button applications requiring frequent operation or higher wear resistance of the seals.

[0027] Example 3

[0028] This embodiment has the same basic structure as Embodiment 1, the main difference being the number of annular grooves 12 and elastic support rings 2. In this embodiment, based on the button's travel length and the required sealing force, five annular grooves 12 are formed in the connecting hole 11, and five elastic support rings 2 are correspondingly embedded therein. A greater number of elastic support rings 2 can provide more linear elasticity and more stable multi-layer sealing contact, making it suitable for applications with extremely stringent sealing performance requirements.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
