[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The winch button of the embodiment of the present invention comprises a button body 1, a dust cover 2, a mounting box 3 and a first sealing ring 4. The mounting box 3 has a mounting cavity 33, and the mounting cavity 33 has an opening upward.

[0031] The dust cover 2 is detachably connected to the mounting box 3 to seal the opening. A mounting hole 23 is provided on the dust cover 2. The button body 1 cooperates with the mounting hole 23 to be installed on the dust cover 2, and one end of the button body 1 extends into the mounting cavity 33. The mounting box 3 is provided with a first groove 22 to install a first sealing ring 4, and the sealing ring is arranged between the dust cover 2 and the mounting box 3.

[0032] Specifically, if Figure 1 to Figure 2 As shown, the mounting box 3 extends in the front-to-back direction, and the height direction of the mounting box 3 is the up-and-down direction. A dust cover 2 is provided above the mounting box 3, and the bottom of the dust cover 2 contacts the mounting box 3 to seal the opening of the mounting cavity 33. For example, the dust cover 2 is snap-fitted to the mounting box 3 to seal the opening of the mounting box 3, and a mounting hole 23 is also provided on the dust cover 2 to facilitate the installation of the button body 1.

[0033] The first sealing ring 4 is arranged on the first groove 22 on the installation box 3, and the first sealing ring 4 is at least partially located outside the first groove 22. Furthermore, a second groove 32 corresponding to the first sealing ring 4 is provided on the protective cover, and the first sealing ring 4 is located in the first groove 22 and the second groove 32 to seal the gap between the protective cover and the installation box 3.

[0034] The first sealing ring 4 is arranged between the dust cover 2 and the mounting box 3, and is used to enhance the sealing effect and prevent the external environment from corroding the internal structure. The dust cover 2 is detachably connected to the mounting box 3, and is used to seal the opening of the mounting cavity 33 to prevent dust and moisture from entering. The dust cover 2 is provided with a mounting hole 23, and the button body 1 is installed on the dust cover 2 through the mounting hole 23, and partially extends into the mounting cavity 33. The connection between the dust cover 2 and the mounting box 3 can be a snap-on connection, which is convenient for disassembly and maintenance. The first sealing ring 4 is at least partially located outside the first groove 22 to better contact with the dust cover 2 and form a seal. The dust cover 2 is provided with a second groove 32 corresponding to the first sealing ring 4, and the first sealing ring 4 is located in the first groove 22 and the second groove 32, which further improves the sealing performance.

[0035] The winch button of the embodiment of the present invention effectively prevents the corrosion of the internal structure of the button by external environmental factors such as dust and moisture through the combination of the first sealing ring 4 and the dust cover 2, thereby improving the reliability and service life of the winch button. The detachable connection design of the dust cover 2 and the installation box 3 facilitates the user to maintain and replace the dust cover 2 or the sealing ring, thereby reducing the maintenance cost. The dust cover 2 is provided with a mounting hole 23, which makes the installation of the button body 1 more convenient and improves the installation efficiency.

[0036] In some embodiments, the sealing box has a bending surface 31 matched with the dust cover 2 , the dust cover 2 has a limiting portion 21 matched with the bending surface 31 , and a portion of the bending surface 31 is in contact with the limiting portion 21 .

[0037] Specifically, Figure 1 to Figure 2 As shown, the bending surface 31 is partially in contact with the lower end of the limiting portion 21, and the bending surface 31 is in a "Z" shape. The limiting portion 21 is in contact with the bottom and the side surface and the bending surface 31 to form an L-shaped sealing structure, thereby preventing the entry of water vapor and dust, and improving the dustproof and moisture-proof properties of the device.

[0038] In some embodiments, the bending surface 31 includes a first section 311, a second section 312 and a third section 313 which are connected in sequence and gradually approach the opening, the first section 311 contacts the bottom of the limiting portion 21, the second section 312 contacts the side of the limiting portion 21, and the third section 313 has a preset distance from the dust cover 2 in the up and down directions.

[0039] Specifically, Figure 1 to Figure 2 As shown, the first section 311 and the third section 313 are arranged in parallel with each other, the first section 311 is arranged orthogonally to the second section 312, the plane where the first section 311 is located is orthogonal to the plane where the second section 312 is located, the second section 312 is in contact with the side of the limiting portion 21, thereby forming an L-shaped sealing structure, and the third section 313 and the part of the dust cover 2 not in the limiting portion 21 have a preset spacing, so as to facilitate the installation of holes on the dust cover 2 and the installation box 3 for installing bolts. At the same time, it is also convenient to install a sponge between the dust cover 2 and the installation box 3 to prevent the entry of water and dust.

[0040] Furthermore, the height of the first section 311 in the vertical direction gradually decreases in the direction away from the mounting box 3 to prevent water from entering between the first section 311 and the limiting portion 21. At the same time, the inclined arrangement also facilitates the discharge of dust and water. The gradual height design forms a wedge-shaped gap to produce a self-cleaning effect using fluid dynamic pressure. When the device vibrates or tilts, the structure can produce a pumping effect to accelerate the discharge of foreign matter.

[0041] In some embodiments, the first groove 22 is disposed at a portion where the mounting box 3 contacts the limiting portion 21 .

[0042] Specifically, Figure 1 to Figure 2 As shown, the first groove 22 is arranged between the dust cover 2 and the installation box 3, and is arranged at the part where the installation box 3 contacts the limiting portion 21, that is, the first section 311 or the second section 312, and cooperates with the L-shaped sealing structure of the first section 311 and the second section 312 to enhance the stability of the protective cover being clamped on the installation box 3 and improve the overall sealing.

[0043] In some embodiments, a first curved surface is disposed at one end of the dust cover 2 facing away from the installation box 3 , and the height of the first curved surface in the up-down direction gradually decreases in a direction away from the installation hole 23 .

[0044] Specifically, Figure 1 to Figure 2As shown, a first curved surface is provided at the upper end of the dust cover 2, and the first curved surface gradually lowers in the up and down direction away from the mounting hole 23, so that when water or dust vibrates in the device, the first curved surface gradually lowers in the direction away from the mounting hole 23. When water or dust tries to enter the device through the dust cover 2, they will be guided by the curved surface and flow to a lower position. Under the action of vibration, the water or dust is thrown away from the dust cover 2 to avoid being sucked into the device. Furthermore, there are multiple mounting holes 23, and the multiple mounting holes 23 are arranged at intervals on the dust cover 2 along the extension direction of the mounting box 3 to facilitate the installation of multiple button bodies 1.

[0045] In some embodiments, the dust cover 2 is made of any one of polytetrafluoroethylene, polyperfluoroethylene propylene or ethylene-tetrafluoroethylene copolymer, and thus has certain hydrophobicity and oleophobicity.

[0046] Polytetrafluoroethylene is formed by the polymerization of tetrafluoroethylene chains. The fluorine atoms in its molecular structure have extremely strong electronegativity and can form stable fluorine-carbon bonds, thus giving the material excellent chemical stability and hydrophobicity.

[0047] PTFE has a low surface energy, which makes it difficult for water and other liquids to wet and spread on its surface, so it exhibits excellent hydrophobicity. At the same time, due to the weak interaction between its molecules, it also has a certain degree of oleophobicity.

[0048] FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The surface of FEP also exhibits low surface energy characteristics, making it difficult for water and oil to adhere to its surface.

[0049] Ethylene-tetrafluoroethylene copolymer is a copolymer of ethylene and tetrafluoroethylene, which combines the flexibility of ethylene and the hydrophobicity of tetrafluoroethylene, making ethylene-tetrafluoroethylene copolymer have good flexibility and processing performance while maintaining hydrophobicity. The surface of ethylene-tetrafluoroethylene copolymer also has low surface energy characteristics, which can effectively prevent the adhesion of water and oil.

[0050] Polytetrafluoroethylene, polyperfluoroethylene propylene and ethylene-tetrafluoroethylene copolymer, due to their unique chemical structure and surface characteristics, all show certain hydrophobicity and oleophobicity. In actual work, the most suitable material of the dust cover 2 can be selected according to the specific needs of the dust cover 2 and the working environment. Waterproof glue is applied between the dust cover 2 and the installation box 3. The staff can improve the waterproof performance and adaptability of the dust cover 2 by selecting silicone sealant, polyurethane sealant, acrylic sealant or butyl rubber sealant.

[0051] In some embodiments, waterproof glue is coated between the dust cover 2 and the installation box 3. The waterproof glue is any one of silicone sealant, polyurethane sealant, acrylic sealant, and butyl rubber sealant. Different types of waterproof glue can be used according to the actual use environment.

[0052] The winch of the embodiment of the present invention includes any winch button. The above is a detailed introduction to one provided by the present invention.
