Description

Technical Field

[0001] This utility model relates to the field of cap technology, specifically a cap that prevents it from falling off. Background Art

[0002] Screws are tools that use the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually fasten objects and machine parts. They are a general term for fasteners and are indispensable industrial necessities in daily life, widely used in various fields. Currently, in order to prevent dust, moisture, and other impurities from entering the screw during use and to prevent the nut from rusting, screw caps are usually used to protect the screw.

[0003] During use, caps on the market are prone to loosening due to long-term vibration in the environment, causing them to fall off. To address this, we propose a cap design that prevents them from falling off. Utility Model Content

[0004] The purpose of this invention is to provide a cap that prevents it from falling off, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cap that prevents detachment, comprising a cap body and a reinforcing component. The cap body is a hemispherical structure with an internal groove. The reinforcing component is disposed on the surface of the cap body and includes a reinforcing ring, a connecting rod, an internally threaded fastener, a pressing auxiliary component, a hemispherical fixing groove, and a hemispherical fixing component. The reinforcing ring is disposed on the lower surface of the cap body, and the connecting rod is slidably connected to the inner surface of the reinforcing ring. An internally threaded fastener is installed at the inner end of the connecting rod, and a pressing auxiliary component is disposed at the end of the connecting rod away from the internally threaded fastener. A hemispherical fixing groove is formed on the outer surface of the reinforcing ring, and a hemispherical fixing component is engaged with the inner side of the hemispherical fixing groove. The hemispherical fixing component is connected to the inner side of the pressing auxiliary component.

[0006] Furthermore, the internal threaded fasteners are provided in four sets, and the internal threaded fasteners are arranged circumferentially and equidistantly on the inner surface of the reinforcing ring.

[0007] Furthermore, both the pressing auxiliary component and the internal thread fastener are rigid structures, and two sets of the pressing auxiliary component and the internal thread fastener are symmetrically arranged.

[0008] Furthermore, the outer surface of the cover is provided with an epoxy resin coating, and the inner surface of the cover is provided with protective components to improve strength.

[0009] Furthermore, the protective component includes a waterproof membrane, a stainless steel woven mesh layer, and a rigid metal protective layer. The waterproof membrane is disposed on the inner surface of the cover body, the inner surface of the waterproof membrane is connected to the stainless steel woven mesh layer, and the inner surface of the stainless steel woven mesh layer is fitted with the rigid metal protective layer.

[0010] Furthermore, the protective component also includes a sealing layer and a polyurea waterproof coating, and the inner surface of the rigid metal protective layer is provided with a sealing layer, and the inner surface of the sealing layer is provided with a polyurea waterproof coating.

[0011] Furthermore, the upper surface of the cover is threaded with a threaded reinforcing rod, and an internal reinforcing component is installed at the bottom of the threaded reinforcing rod.

[0013] This utility model provides a cap that prevents it from falling off, which has the following beneficial effects:

[0014] 1. This utility model incorporates a reinforcing component, which includes a reinforcing ring, a connecting rod, an internally threaded fastener, a pressing auxiliary component, a hemispherical fixing groove, and a hemispherical fixing component. In use, after the device is connected to the screw via a nut, the pressing auxiliary component is pressed inwards. This causes the pressing auxiliary component to move the connecting rod inwards along the inner side of the reinforcing ring. The connecting rod then moves the internally threaded fastener inwards until the hemispherical fixing component on the surface of the pressing auxiliary component engages with the hemispherical fixing groove on the surface of the reinforcing ring. This allows the inner surface of the internally threaded fastener to embed and connect with the inner end surface of the screw, further securing the cap and screw and preventing loosening due to continuous vibration during use.

[0015] 2. This utility model incorporates a protective component, which includes a waterproof membrane, a stainless steel woven mesh layer, and a hard metal protective layer. The component also includes a sealing layer and a polyurea waterproof coating. During use, the epoxy resin coating improves the wear resistance of the outer surface of the cover, the waterproof membrane effectively enhances the waterproofing of the cover, the stainless steel woven mesh layer increases the hardness of the cover, and the hard metal protective layer strengthens the compressive strength of the cover, thus effectively increasing its overall strength. The sealing layer enhances the internal sealing, and the polyurea waterproof coating further improves the waterproofing performance and prevents internal rusting. This enhances the overall strength of the device, thereby increasing its protective properties and extending its service life. Attached Figure Description

Then, the connecting rod 202 drives the internal thread fastener 203 to move inward until the hemispherical fixing part 206 on the surface of the pressing auxiliary part 204 engages with the hemispherical fixing groove 205 on the surface of the reinforcing ring 201, so that the inner surface of the internal thread fastener 203 can be embedded and connected with the inner end surface of the screw.

[0023] Please refer to Figures 1 to 2Four sets of internal threaded fasteners 203 are provided, and the internal threaded fasteners 203 are arranged in a ring at equal intervals on the inner surface of the reinforcing ring 201. The pressing auxiliary component 204 and the internal threaded fasteners 203 are both rigid structures, and two sets of pressing auxiliary component 204 and internal threaded fasteners 203 are symmetrically arranged. The upper surface of the cover 1 is threadedly connected to a threaded reinforcing rod 5, and an internal reinforcing component 6 is installed at the bottom of the threaded reinforcing rod 5. A nut 7 is provided at the bottom of the reinforcing ring 201, and an elastic sealing gasket 8 is connected to the lower surface of the nut 7.

[0024] The specific operation is as follows: When in use, connect the device to the outer end of the screw by threading the nut 7.

[0027] In summary, as Figures 1 to 3As shown, when using this anti-slip cap, firstly, the device is threaded onto the outer end of the screw using the nut 7. The elastic sealing gasket 8 can improve the tightness of the connection. Rotate the threaded reinforcing rod 5 to move it inward until the internal reinforcing part 6 abuts against the inner side of the screw, thereby further reinforcing the installation of the device. Then, press the pressing auxiliary part 204 inward, causing the pressing auxiliary part 204 to move the connecting rod 202 inward along the inner side of the reinforcing ring 201. In turn, the connecting rod 202 drives the internal threaded fastener 203 to move inward until the hemispherical fixing part 206 on the surface of the pressing auxiliary part 204 and the screw are aligned. The hemispherical fixing groove 205 on the surface of the reinforcing ring 201 engages and connects, so that the inner surface of the internal thread fastener 203 can be embedded and connected with the inner end surface of the screw. During the use of this device, the epoxy resin coating 3 can improve the wear resistance of the outer surface of the cover 1, the waterproof membrane 401 can effectively improve the waterproof function of the cover 1, the stainless steel woven mesh layer 402 can improve the hardness of the cover 1, the hard metal protective layer 403 can enhance the compressive strength of the cover 1, thereby effectively improving the strength of the cover 1, the sealing layer 404 can strengthen the internal sealing, and the polyurea waterproof coating 405 can further improve the waterproof performance and prevent internal rusting.
