[0001] The utility model relates to the technical field of bolts, in particular to a waterproof bolt. Background Art
[0002] A bolt is a cylindrical threaded fastener used with a nut. It is a type of fastener composed of two parts: a bolt head and a screw rod (a cylinder with external threads). It needs to be used in conjunction with a nut to firmly connect two parts with through holes, and is usually made of materials such as carbon steel, alloy steel, and stainless steel.
[0003] The above-mentioned and existing technologies have the following defects: During the use of bolts, the bolt heads are usually exposed. Therefore, the bolt heads are easily eroded by rainwater, which easily shortens the service life at the bolt head, reducing the strength and service effect of the bolts.
[0004] Therefore, a waterproof bolt is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to solve the defect that the bolt heads are usually exposed, so the bolt heads are easily eroded by rainwater, which easily shortens the service life at the bolt head, and a waterproof bolt is proposed.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A waterproof bolt includes a screw rod. One end of the screw rod is fixedly connected with a bolt head. The arc surface of the screw rod is threadedly connected with a nut. Sliding grooves are opened on the surfaces of the bolt head and the screw rod. A sliding rod is slidably connected to the inner wall of the sliding groove. One end of the sliding rod is fixedly connected with a waterproof cover. The lower end of the waterproof cover is fixedly connected with a sealing ring.
[0007] The effects achieved by the above components are as follows: By setting the waterproof cover and the sealing ring, when the waterproof cover moves, the sealing ring will be pressed against the surface of the fastener to be fastened. After being squeezed, the sealing ring will deform to improve the sealing performance between the waterproof cover and the fastener to be fastened. The waterproof cover and the sealing ring cooperate to prevent rainwater from eroding the bolt head when the bolt head is in an exposed environment, thereby prolonging the service life of the bolt head and improving the service effect of the bolt.
[0008] Preferably, an elastic buckle is fixedly connected to the inner wall of the waterproof cover. A clamping groove is opened on the side wall of the bolt head. The size of the clamping groove is adapted to the size of the elastic buckle.
[0009] The effects achieved by the above components are as follows: After the lower end of the elastic buckle is aligned with the clamping groove, the elastic buckle will return to its original state by its own elastic force and engage with the clamping groove. The clamping groove serves to limit the position of the elastic buckle, thereby restricting the position of the waterproof cover.
[0010] Preferably, the sliding rod has a regular hexagonal prism structure.
[0011] The effects achieved by the above components are as follows: The slide bar in the shape of a regular hexagonal prism restricts the movement path of the waterproof cover, ensuring that the elastic buckle can be aligned with the card slot.
[0012] Preferably, a guiding block is fixedly connected to the lower end of the slide bar.
[0013] The effects achieved by the above components are as follows: The guiding block can guide the slide bar, facilitating the insertion of the slide bar into the inner wall of the sliding groove.
[0014] Preferably, a protective ring is slidably connected to the arc surface of the protective cover. An annular groove is formed in the arc surface of the protective cover. A circular ring is slidably connected to the inner wall of the annular groove, and the circular ring is fixedly connected to the protective ring.
[0015] The effects achieved by the above components are as follows: The sliding of the circular ring drives the sliding of the protective ring. The protective ring shields the outer periphery of the sealing ring, protecting the sealing ring, thereby extending the service life of the sealing ring. The cooperation between the annular groove and the circular ring can limit the position of the protective ring.
[0016] Preferably, a spring is fixedly connected to the surface of the circular ring, and one end of the spring is fixedly connected to the inner wall of the annular groove.
[0017] The effects achieved by the above components are as follows: During the movement of the waterproof cover, the spring makes the circular ring slide along the inner wall of the annular groove by virtue of its own elastic force.
[0018] Compared with the prior art, the advantages and positive effects of the present utility model are as follows
[0019] In the present utility model, by providing a waterproof cover and a sealing ring, the movement of the waterproof cover causes the sealing ring to abut against the surface of the component to be fastened. After being squeezed, the sealing ring deforms to improve the sealing performance between the waterproof cover and the component to be fastened. The cooperation between the waterproof cover and the sealing ring can prevent rainwater from eroding the screw head when the screw head is in an exposed environment, thereby extending the service life of the screw head and improving the use effect of the bolt.

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0026] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.
[0027] As Figures 1 - 4 shown, the present invention provides a waterproof bolt, which includes a screw rod 1. One end of the screw rod 1 is fixedly connected with a screw head 2. The arc surface of the screw rod 1 is threadedly connected with a nut 3. Slide grooves 4 are formed on the surfaces of the screw head 2 and the screw rod 1. A slide bar 5 is slidably connected to the inner wall of the slide groove 4. One end of the slide bar 5 is fixedly connected with a waterproof cover 6. A sealing ring 7 is fixedly connected to the lower end of the waterproof cover 6. By providing the waterproof cover 6 and the sealing ring 7, when the waterproof cover 6 moves, the sealing ring 7 will abut against the surface of the fastener to be fastened. After being squeezed, the sealing ring 7 will deform to improve the sealing performance between the waterproof cover 6 and the fastener to be fastened. The cooperation of the waterproof cover 6 and the sealing ring 7 can prevent rainwater from eroding the screw head 2 when the screw head 2 is in an exposed environment, thereby extending the service life of the screw head 2 and improving the use effect of the bolt. An elastic buckle 9 is fixedly connected to the inner wall of the waterproof cover 6. A card slot 8 is formed on the side wall of the screw head 2. The size of the card slot 8 is adapted to the size of the elastic buckle 9. After the lower end of the elastic buckle 9 is aligned with the card slot 8, the elastic buckle 9 will restore its original shape by virtue of its own elasticity and engage with the card slot 8. The card slot 8 serves to limit the position of the elastic buckle 9, thereby limiting the position of the waterproof cover 6. The slide bar 5 has a regular hexagonal prism structure. The slide bar 5 with a regular hexagonal prism structure will limit the movement path of the waterproof cover 6 to ensure that the elastic buckle 9 can be aligned with the card slot 8.
[0028] As Figures 2 - 4As shown in the figure, a guide block 10 is fixedly connected to the lower end of the sliding rod 5. The guide block 10 can guide the sliding rod 5, facilitating the insertion of the sliding rod 5 into the inner wall of the chute 4. A protective ring 11 is slidably connected to the arc surface of the protective cover. An annular groove 12 is formed in the arc surface of the protective cover. A ring 13 is slidably connected to the inner wall of the annular groove 12. The ring 13 is fixedly connected to the protective ring 11. The sliding of the ring 13 will drive the sliding of the protective ring 11. The protective ring 11 will block the outer periphery of the sealing ring 7 to protect the sealing ring 7, thereby extending the service life of the sealing ring 7. The cooperation between the annular groove 12 and the ring 13 can limit the position of the protective ring 11. A spring 14 is fixedly connected to the surface of the ring 13. One end of the spring 14 is fixedly connected to the inner wall of the annular groove 12. During the movement of the waterproof cover 6, the spring 14 will cause the ring 13 to slide along the inner wall of the annular groove 12 by virtue of its own elastic force.
[0029] The overall working principle is as follows: When a bolt is needed, the screw rod 1 is passed through the fastener to be fastened, and then the nut 3 is tightened for fastening. Then, the waterproof cover 6 is moved. The movement of the waterproof cover 6 will drive the movement of the sliding rod 5, and the movement of the sliding rod 5 will drive the movement of the guide block 10. The guide block 10 can guide the sliding rod 5, facilitating the insertion of the sliding rod 5 into the inner wall of the chute 4. Then, the sliding rod 5 with a regular hexagonal prism structure will limit the movement path of the waterproof cover 6. The waterproof cover 6 will make the elastic buckle 9 contact the screw head 2. The screw head 2 will squeeze the elastic buckle 9 to make the elastic buckle 9 bend. When the waterproof cover 6 abuts against the surface of the screw head 2, the lower end of the elastic buckle 9 will be aligned with the card slot 8. At this time, the elastic buckle 9 will restore its original shape by virtue of its own elastic force and engage with the card slot 8. The card slot 8 can limit the position of the elastic buckle 9, thereby restricting the position of the waterproof cover 6. The movement of the waterproof cover 6 will make the sealing ring 7 abut against the surface of the fastener to be fastened. After being squeezed, the sealing ring 7 will deform to improve the sealing performance between the waterproof cover 6 and the fastener to be fastened. The cooperation between the waterproof cover 6 and the sealing ring 7 can prevent rainwater from eroding the screw head 2 when the screw head 2 is in an exposed environment, thereby extending the service life of the screw head 2. During the movement of the waterproof cover 6, the spring 14 will cause the ring 13 to slide along the inner wall of the annular groove 12 by virtue of its own elastic force. The sliding of the ring 13 will drive the sliding of the protective ring 11. The protective ring 11 will block the outer periphery of the sealing ring 7 to protect the sealing ring 7, thereby extending the service life of the sealing ring 7. The cooperation between the annular groove 12 and the ring 13 can limit the position of the protective ring 11.
[0030] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
