[0001] The utility model relates to the technical field of nuts, in particular to a hexagonal nut with heat corrosion resistance. Background Art

[0002] Nuts are nuts that are screwed together with bolts or screws to tighten. They are a must-have component for all manufacturing machinery. They are divided into several types according to the material, such as carbon steel, non-ferrous metals (such as copper), etc. When the existing nuts are used, bolts are inserted inside. When the bolts are inserted into the nuts, some corrosive liquids are easily brought into the nuts. The corrosive liquids cause serious damage to the nuts, affecting the use of the nuts.

[0003] The publication number is CN216009186U, which describes a nut structure with anti-rust and corrosion resistance, including a nut body, a protective mechanism disposed on the top of the nut body, and a contraction mechanism disposed on the inner wall of the nut body. The protective mechanism includes a protective ring, a cover ring, a first slide bar, and a wiping assembly. By extending one end of the bolt through the cover ring into the interior of the protective ring, the outer surface of the bolt will contact the wiping pad, and the wiping pad will push the special-shaped clamp block to slide on the two first slide bars and press the two first springs at the same time. The two first springs contract to generate elastic force, which is applied to the wiping pad through the special-shaped clamp block, and the wiping pad will press on the outer surface of the bolt.

[0004] Based on the above technical features, the problem that arises is that in the prior art, the wiping pad can only wipe the outer surface of the bolt. The reality is that there are a lot of oil stains and other corrosive substances hidden on the outer surface of the bolt and in the thread groove of the bolt. Therefore, the cleanliness of the oil stain cleaning structure is low and the cleaning effect is not good.

[0005] Therefore, it is necessary to solve the above problems by a hexagonal nut with heat corrosion resistance. Utility Model Content

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Embodiment 1

[0021] The utility model provides a hexagonal nut with heat and corrosion resistance, comprising a nut body 1. Figure 1 As shown, a collar 2 is coaxially fixedly connected to the nut body 1 , and an end of the collar 2 away from the nut body 1 is coaxially fixedly connected to a circular annular fixing ring 4 .

[0022] like Figure 2 As shown, a wiping pad 3 in the shape of a circular ring is coaxially fixed in the collar 2, and the wiping pad 3 is in sliding contact with the outer surface of the bolt to wipe the outer surface of the bolt. A plurality of cleaning blocks 5 are welded on the inner curved surface of the fixing ring 4, and each cleaning block 5 matches the thread groove of the bolt thread part. The fixing ring 4 cooperates with the bolt thread through the plurality of cleaning blocks 5, and each cleaning block 5 slides along the thread groove to clean out the stains in the thread groove.

[0023] like Figure 2 Two mounting grooves are cut out inside the nut body 1, and the two mounting grooves are symmetrical about the central axis of the nut body 1. A screw-assisting mechanism is installed in each mounting groove, which facilitates the constructor to screw the nut body 1. Each screw-assisting mechanism includes a hand-held block 8 and a pop-up assembly. The hand-held block 8 matches the mounting groove and is limitedly slidably matched with the mounting groove. The hand-held block 8 slides radially along the threaded hole of the nut body 1. The pop-up assembly is connected to the hand-held block 8 in a transmission manner, and is used to push the hand-held block 8 out of the mounting groove.

[0024] The pop-up assembly includes a telescopic rod 6 and a spring 7. The telescopic rod 6 is fixedly connected to the nut body 1 and arranged along the radial direction of the threaded hole of the nut body 1. The output end of the telescopic rod 6 is fixedly connected to the hand-held block 8 to ensure the stable sliding of the hand-held block 8. The spring 7 is sleeved on the telescopic rod 6, one end of the spring 7 is fixedly connected to the nut body 1, and the other end is fixedly connected to the hand-held block 8, which is used to pop the hand-held block 8 out of the installation slot and ensure that the hand-held block 8 does not completely slide out of the installation slot.

[0025] Working principle of embodiment 1:

[0026] When in use, the fixing ring 4 is placed directly against the bolt, and then a torsional force is applied to the two hand-held blocks 8. The two hand-held blocks 8 drive the nut body 1 to rotate, the nut body 1 drives the collar 2 to rotate, and the collar 2 drives the fixing ring 4 to rotate. Since the fixing ring 4 is threadedly connected to the bolt through a plurality of cleaning blocks 5, each cleaning block 5 slides into the thread groove of the bolt thread portion and slides in the thread groove, and the fixing ring 4 moves along the axial direction of the bolt. When the cleaning block 5 slides in the thread groove, the corrosive stains in the thread groove are pushed out.

[0027] During the axial movement of the fixing ring 4 along the bolt, the fixing ring 4 drives the sleeve ring 2 to move along the bolt, and the sleeve ring 2 drives the internal wiping pad 3 to move along the bolt, and the wiping pad 3 wipes the outer surface of the bolt and wipes the stains toward the nut.

[0028] As the twisting continues, the nut body 1 is threadedly connected with the threaded portion of the cleaned and wiped bolt, ensuring that the corrosive stains are in contact with the nut body 1, thereby improving the cleanliness, enhancing the cleaning effect, and increasing the life of the nut. Embodiment 2

[0029] like Figure 3-Figure 4 A hexagonal nut with heat corrosion resistance is shown. The difference between this embodiment and the first embodiment is that the ejection assembly includes a first magnet 9, a baffle 10 and a second magnet 11. The first magnet 9 is fixedly connected to the nut body 1, and the second magnet 11 is fixedly connected to the hand-held block 8. The first magnet 9 and the second magnet 11 are magnetically matched, and the end of the second magnet 11 close to the first magnet 9 is cut with an inclined surface. The baffle 10 is slidably inserted into the mounting groove of the nut body 1 and is located between the first magnet 9 and the second magnet 11. The baffle 10 is both in sliding contact with the first magnet 9 and in transmission cooperation with the second magnet 11. The end of the baffle 10 inserted into the mounting groove is a wedge-shaped end, which matches the inclined surface of the second magnet 11 and is in contact and sliding contact, and is used to push the second magnet 11 away from the first magnet 9. The baffle 10 is made of magnetic conductive material, and the first magnet 9 and the second magnet 11 are both squeezed and matched with the baffle 10 to ensure that the hand-held block 8 will not completely slide out of the mounting groove.

[0030] Working principle of the second embodiment:

[0031] The difference between this working principle and the working principle of the first embodiment is that the working principle of the pop-up component is different. Now only the working principle of the pop-up component is described in detail, and the other processes are the same as those of the first embodiment.

[0032] When the nut body 1 is turned, first insert the baffle 10 into the corresponding mounting groove along the axial direction of the nut body 1. In this process, the wedge-shaped end of the baffle 10 is inserted from between the first magnet 9 and the second magnet 11 and is in sliding contact with both the first magnet 9 and the inclined surface on the second magnet 11. As the baffle 10 continues to be inserted, the first magnet 9 and the second magnet 11 are released from attraction, and the baffle 10 pushes the second magnet 11 to slide away from the first magnet 9 and gradually slide out of the mounting groove. When the baffle 10 abuts against the nut body 1, the insertion stops. At this time, since the baffle 10 is made of magnetic conductive material, the first magnet 9 and the second magnet 11 are squeezed and matched with the baffle 10 due to magnetic attraction, and the second magnet 11 does not completely push the hand-held block 8 out of the mounting groove due to magnetic attraction.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
