[0001] The utility model relates to the technical field of bolts, in particular to a waterproof and antioxidant bolt. Background Art
[0002] Currently, in order to improve the waterproof and antioxidant properties of bolts, their surfaces are usually specially treated. For example, methods such as galvanizing, painting, nickel plating, etc. can effectively isolate the direct contact between air and moisture and the bolt substrate, thereby slowing down the rate of oxidation reaction.
[0003] In addition, waterproof bolts are usually equipped with sealing rings made of rubber or plastic. When the bolt and the nut or other connectors are rotated and tightly connected, the sealing ring is compressed to form a tight seal, effectively preventing the intrusion of external factors such as moisture, dust, and air.
[0004] Among them, large bolts, as important fasteners, are widely used in many fields such as bridges, buildings, mechanical equipment, transportation, etc. However, during the operation of the equipment, the wear or aging of the sealing ring is a common problem and needs to be replaced regularly to ensure the sealing performance of the equipment. At this time, it is necessary to disconnect the connection between the bolt and the nut or other connectors, which is time-consuming and laborious, and multiple disconnections are likely to cause damage to the threads of the bolt.

Specific implementation manner
[0026] By providing a waterproof and antioxidant bolt in the embodiments of the present application, the technical problem that replacing the sealing ring requires disconnecting the connection between the bolt and the nut or other connectors, which is time-consuming and laborious and prone to thread damage of the bolt due to multiple disconnections, is effectively solved.
[0027] Embodiment
[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 And Figure 8 , the technical solutions in the embodiments of the present application effectively solve the technical problem that replacing the sealing ring requires disconnecting the connection between the bolt and the nut or other connectors, which is time-consuming and laborious and prone to thread damage of the bolt due to multiple disconnections. The general idea is as follows:
[0029] In view of the problems existing in the prior art, the utility model provides a waterproof and antioxidant bolt. The waterproof and antioxidant bolt includes a bolt head 1, and a threaded column 2 is arranged outside the bolt head 1. The bolt is divided into two parts, namely the bolt head 1 and the threaded column 2. And a structure for connecting between the bolt head 1 and the threaded column 2 is arranged outside the threaded column 2. The structure itself does not directly affect the compressive performance of the bolt. The compressive performance of the bolt mainly depends on factors such as the material of the bolt, heat treatment, diameter, length, and the stress level it bears. At the same time, the added structures are all outside the threaded column 2 and do not contact the connecting piece with the bolt head 1. Therefore, it does not affect the connection of the threaded column 2. A waterproof ring 3 is movably connected outside the threaded column 2. The waterproof ring 3 is composed of a cylinder and a frustum. A connecting mechanism is arranged outside the bolt head 1. The connecting mechanism includes a clamping groove 4, a limiting groove 5, a clamping column 6, a groove 7, a screw rod 8, and a limiting block 9. The clamping groove 4 is opened outside the bolt head 1. There are two limiting grooves 5, and both of the two limiting grooves 5 are opened inside the clamping groove 4. The clamping column 6 is clamped inside the clamping groove 4. The groove 7 is opened outside the clamping column 6. The groove 7 is located at the end of the clamping column 6 away from the threaded column 2. The screw rod 8 is rotatably connected inside the groove 7. The screw rod 8 is composed of two threaded rods with opposite threads. There are two limiting blocks 9, and both of the two limiting blocks 9 are threadedly connected outside the screw rod 8. The limiting block 9 is slidably connected inside the limiting groove 5. The clamping column 6 is fixedly installed outside the threaded column 2. By setting the waterproof ring 3 and cooperating with the clamping column 6, when the waterproof ring 3 needs to be replaced, rotate the screw rod 8 to release the connection between the limiting block 9 and the limiting groove 5. At this time, the connection between the clamping groove 4 and the clamping column 6 is released. At this time, the waterproof ring 3 can be pulled to release the connection between the waterproof ring 3 and the threaded column 2. At this time, the waterproof ring 3 is disassembled. At this time, a new waterproof ring 3 is slidably connected outside the threaded column 2. At this time, the bolt head 1 is clamped outside the clamping column 6 through the clamping groove 4. Then rotate the screw rod 8 in the reverse direction to make the limiting block 9 enter the limiting groove 5 to fix the clamping column 6 inside the clamping groove 4. At this time, the installation of the waterproof ring 3 is completed. Without releasing the connection between the bolt and the connecting piece, the waterproof ring 3 can be replaced, thereby extending the service life of the bolt.
[0030] Through holes 10 are opened at both ends of the clamping column 6. The through holes 10 communicate with the inside of the groove 7. An installation groove 11 is opened on the surface of the bolt head 1 close to the threaded column 2. The limiting block 9 is slidably connected inside the limiting groove 5 through the through hole 10. One end of the waterproof ring 3 is clamped inside the installation groove 11. The waterproof ring 3 is made of silica gel material to reduce the probability of the waterproof ring 3 falling off.
[0031] Two support frames 12 are fixedly installed inside the groove 7. The support frame 12 is composed of a cuboid plate and a circular ring. The screw rod 8 is rotatably connected to the inner sides of the two support frames 12, which is a structure for the screw rod 8 to rotate inside the groove 7. An internal groove 13 is formed on the inner side of each support frame 12. Two internal plates 14 are fixedly installed on the outer part of the screw rod 8. The two internal plates 14 are located between the two limit blocks 9. The screw rod 8 is rotatably connected to the inside of the internal groove 13 through the internal plates 14, preventing the screw rod 8 from moving on the support frame 12.
[0032] A rotating disk 16 is fixedly installed on the outer part of the screw rod 8. The rotating disk 16 facilitates the operator to rotate the screw rod 8. The rotating disk 16 is composed of a cylinder and several cuboids. The rotating disk 16 is located between the two limit blocks 9. A protective plate 15 is arranged on the outer part of the rotating disk 16. A magnetic block 17 is fixedly installed on the outer part of the clamping post 6. Since the protective plate 15 is made of iron, when it contacts or approaches the magnetic block 17, it will be strongly attracted by the magnetic field of the magnetic block 17. This magnetic force can ensure that the protective plate 15 is firmly attached to the magnetic block 17 and is not easy to fall off or shift. Openings 18 are formed at both ends of the magnetic block 17. Support plates 19 are slidably connected to the inside of the two openings 18. The support plates 19 are T-shaped. The support plates 19 prevent the protective plate 15 from falling when it separates from the magnetic block 17. The two support plates 19 are respectively fixedly installed at both ends of the protective plate 15. By setting the protective plate 15 and cooperating with the rotating disk 16, when the rotating disk 16 is operated, the protective plate 15 is pushed to release the connection between the protective plate 15 and the magnetic block 17. At this time, the support plates 19 move inside the openings 18. At this time, the rotating disk 16 can be operated. After the operation is completed, the protective plate 15 is pushed to cover the rotating disk 16, preventing the rotating disk 16 from being accidentally touched and rotated, and ensuring the stability of the connection between the limit block 9 and the limit groove 5.
[0033] Working principle:
[0034] First step, at this time, the waterproof ring 3 is slidably connected to the outer part of the threaded column 2. At this time, the bolt head 1 is clamped to the outer part of the clamping post 6 through the card slot 4. At this time, one end of the waterproof ring 3 is clamped inside the installation groove 11. At this time, the rotating disk 16 is rotated to drive the screw rod 8 to rotate. The screw rod 8 is composed of two threaded rods with opposite threads. At this time, the two limit blocks 9 move in opposite directions as the screw rod 8 rotates. At this time, the limit blocks 9 enter the limit groove 5 to fix the clamping post 6 inside the card slot 4. At this time, the installation of the waterproof ring 3 is completed;
[0035] Second step, push the protective plate 15 to cover the rotating disk 16 with the protective plate 15. At this time, the protective plate 15 is in contact with the magnetic block 17. Since the material of the protective plate 15 is iron, when it comes into contact with or approaches the magnetic block 17, it will be strongly attracted by the magnetic field of the magnetic block 17. This magnetic force can ensure that the protective plate 15 is firmly attached to the magnetic block 17 and is not easily detached or displaced. At the same time, the protective plate 15 prevents the rotating disk 16 from being accidentally touched and rotated, ensuring the stability of the connection between the limiting block 9 and the limiting groove 5.
[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
