[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a novel corrosion-resistant nut, comprising: a nut body 1, a fixed gasket 2 is fixedly connected to the bottom of the nut body 1, a fixed sleeve 3 is fixedly connected to the top of the fixed gasket 2, and an anti-slip pattern 5 is provided on the outer surface of the nut body 1; an anti-corrosion component 6, the anti-corrosion component 6 is located at the outer side of the nut body 1, the anti-corrosion component 6 comprises a collar 601, a plurality of through holes 604 are uniformly provided on the inner surface of the collar 601, a plurality of fixing plates 605 are uniformly fixedly connected to the inner surface of the collar 601, an insert block 611 is fixedly connected to the bottom of the collar 601, a plurality of second springs 613 are uniformly fixedly connected to the bottom of the insert block 611, a filling pipe 602 is fixedly connected to the bottom of the collar 601, a sealing cover 603 is threadedly connected to the outer surface of the filling pipe 602, the filling pipe 602 is connected to the collar 601 in communication, a threaded sleeve 614 is threadedly connected to the outer surface of the collar 601, an anti-slip sleeve 615 is adhered to the outer surface of the threaded sleeve 614, and an insert block 611 is fixedly connected to the bottom of the collar 601. The block 611 is located at the inner side of the fixed sleeve 3, the outer surface of the plug block 611 is plugged and connected with the inner surface of the fixed sleeve 3, the multiple second springs 613 are all located at the inner side of the fixed sleeve 3, the lower end surfaces of the multiple second springs 613 are all fixedly connected with the inner bottom of the fixed sleeve 3, the inner surface of the fixed sleeve 3 is evenly fixedly connected with multiple blocks 4, the outer surface of the plug block 611 is evenly provided with multiple slots 612, the inner surface of the slots 612 is plugged and connected with the outer surface of the block 4, the inner surface of the collar 601 is in contact with the outer surface of the nut body 1, the number of the fixing plates 605 and the through holes 604 are equal, the outer surface of the fixing plate 605 close to the nut body 1 is fixedly connected with the first spring 606, the end surface of the first spring 606 is fixedly connected with the support ring 607, the first ball 608 is arranged between the outer surface of the support ring 607 and the inner surface of the collar 601, the first ball 608 is located at the inner side of the through hole 604, and the outer surface of the first ball 608 is in contact with the outer surface of the nut body 1.

[0026] The effect achieved by the entire embodiment 1 is that when the nut is in use, the threaded sleeve 614 is screwed and sleeved on the outer side of the collar 601, so that there is a storage space inside the collar 601, and the corrosion-resistant coating can be injected into the collar 601 through the filling pipe 602. When the nut body 1 is in a stationary state, the rebound force of the first spring 606 is utilized to make the support ring 607 press the first ball 608 on the position of the through hole 604, so that the position of the through hole 604 is blocked by the first ball 608, and the nut body 1 can be screwed with a wrench to complete the tightening. When the wrench is screwed on the outer side of the nut body 1, the wrench moves down from the top, so that the nut body 1 is inserted into the inner side of the wrench. At this time, the collar 601 will contact the wrench, so that the collar 601 is pressed down, and the second spring 613 contracts at the same time. At this time, the collar 601 moves down, and the outer side of the nut body 1 is exposed and completely engaged with the wrench. The nut body 1 can be driven to rotate and tightened by screwing the wrench. During the downward movement of the collar 601, the matching arrangement of the block 4 and the slot 612 can prevent the collar 601 from rotating, thereby avoiding the application of a rotational force to the second spring 613 to cause damage thereto. When the collar 601 moves, the first ball 608 will contact and roll with the outer wall of the nut body 1. The corrosion-resistant coating stored in the collar 601 can be brought out and smeared on the surface of the nut body 1 through the rolling of the first ball 608. By providing the anti-slip groove 5 on the surface of the nut body 1, the contact surface of the nut body 1 is made rougher, thereby being able to absorb more corrosion-resistant coating. Each time the nut body 1 is tightened with a wrench, the collar 601 is pressed downward to drive the first ball 608 to roll and smear the corrosion-resistant coating on the surface of the nut body 1, so that a layer of corrosion-resistant coating is always attached to the surface of the nut body 1 during use, thereby avoiding the problem of the corrosion-resistant coating falling off due to tightening the nut, thereby improving the service life of the nut.

[0027] Embodiment 2, as Figure 1-Figure 4 As shown, a backing plate 609 is fixedly connected to the top of the collar 601 , and a plurality of circular grooves are evenly formed on the top of the backing plate 609 , and second balls 610 are disposed inside the plurality of circular grooves.

[0028] The effect achieved by the entire embodiment 2 is that when the wrench is pressed on the upper side of the ring 601 to screw the nut body 1, the wrench will contact the second ball 610, and the rolling of the second ball 610 can reduce the friction, thereby reducing the wear of the ring 601.

[0029] Working principle: When the nut is in use, the threaded sleeve 614 is screwed onto the outer side of the collar 601, so that a storage space exists inside the collar 601. The corrosion-resistant coating can be injected into the collar 601 through the filling pipe 602. When the nut body 1 is in a stationary state, the rebound force of the first spring 606 is utilized to make the support ring 607 press the first ball 608 onto the position of the through hole 604, so that the position of the through hole 604 is blocked by the first ball 608. The nut body 1 can be tightened by screwing it with a wrench. When the spanner cover is screwed on the outside of the nut body 1, the spanner moves down from the top, so that the nut body 1 is inserted into the inside of the spanner. At this time, the collar 601 will contact the spanner, so that the collar 601 is pressed down, and the second spring 613 contracts. At this time, the collar 601 moves down, and the outside of the nut body 1 is exposed and completely engaged with the spanner. The nut body 1 can be rotated and tightened by twisting the spanner. In the process of the collar 601 moving down, the collar 601 can be prevented from rotating by the matching arrangement of the clamping block 4 and the clamping groove 612. Thereby, it is possible to avoid applying a rotational force to the second spring 613 to cause damage thereto. When the collar 601 moves, the first ball 608 will contact and roll with the outer wall of the nut body 1. The corrosion-resistant coating stored in the collar 601 can be brought out and smeared on the surface of the nut body 1 by the rolling of the first ball 608. By providing the anti-slip groove 5 on the surface of the nut body 1, the contact surface of the nut body 1 is made rougher, so that more corrosion-resistant coating can be absorbed. Every time the nut body 1 is tightened with a wrench, the collar 601 is pressed down to drive the first ball 608 to roll and smear the corrosion-resistant coating on the surface of the nut body 1, so that a layer of corrosion-resistant coating is always attached to the surface of the nut body 1 during use, avoiding the problem that the corrosion-resistant coating will fall off when the nut is tightened, thereby improving the service life of the nut. When the wrench is pressed on the upper side of the collar 601 to tighten the nut body 1, the wrench will contact the second ball 610. The rolling of the second ball 610 can reduce friction, thereby reducing the wear of the collar 601.
