[0003] Due to the different environments in which bolts are installed and used, they are often placed in external environments. After the bolts are installed, the heads of the bolts are exposed to the outside and are easily exposed to wind and rain, which makes the bolts susceptible to corrosion and rust. During disassembly, the bolts are prone to thread slippage, which reduces their service life and makes them inconvenient to use. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide an oxidation-resistant and corrosion-resistant bolt, which can solve the problem that after the bolt is installed, the head of the bolt is exposed to the outside and is easily exposed to wind and rain, causing the bolt to be easily corroded and rusted, and prone to thread slippage during disassembly, thereby reducing the service life and causing inconvenience in use.

[0005] To achieve the above object, the utility model provides the following technical solution: an oxidation-resistant and corrosion-resistant bolt, comprising a bolt, wherein the outer wall of the bolt is fixedly sleeved with a support sleeve, the upper surface of the support sleeve is provided with an arc-shaped groove, and the inner wall of the arc-shaped groove is movably clamped with a protective cover;

[0006] The top of the protective cover is fixedly connected to two springs, the lower surfaces of the two springs are fixedly connected to connecting plates, and the opposite surfaces of the two connecting plates are fixedly connected to connecting rods;

[0007] The upper end of the connecting rod slides through the upper surface of the protective cover, and the upper end of the connecting rod is provided with a first cross slot.

[0026] See also Figure 1-4 The utility model provides a technical solution: an oxidation-resistant and corrosion-resistant bolt, comprising a bolt 1, a support sleeve 2 fixedly sleeved on the outer wall of the bolt 1, an arc-shaped groove 11 formed on the upper surface of the support sleeve 2, and a protective cover 3 movably clamped on the inner wall of the arc-shaped groove 11;

[0027] Among them, the top of the protective cover 3 is fixedly connected to two springs 6, the lower surfaces of the two springs 6 are fixedly connected to a connecting plate 7, and the opposite surfaces of the two connecting plates 7 are fixedly connected to a connecting rod 4;

[0028] The upper end of the connecting rod 4 slides through the upper surface of the protective cover 3 , and a first cross slot 5 is formed at the upper end of the connecting rod 4 .

[0029] Furthermore, a cross clamping plate 10 is fixedly connected to the lower surface of the connecting rod 4 , and a second cross clamping groove 12 adapted to the cross clamping plate 10 is formed on the upper surface of the bolt 1 .

[0030] Furthermore, two mounting holes 13 are defined on the lower surface of the protective cover 3 .

[0031] Furthermore, three arc-shaped slots 14 are formed on the inner walls of the two mounting holes 13 .

[0032] Furthermore, two mounting rods 9 adapted to the mounting holes 13 are fixedly connected to the inner wall of the arc-shaped groove 11 .

[0033] Furthermore, three arc-shaped rubber sleeves 8 are fixedly sleeved on the outer walls of the two mounting rods 9 .

[0034] Furthermore, when installing the bolt 1 and the protective cover 3, first insert the two mounting rods 9 into the inner walls of the two mounting holes 13. When the arc-shaped rubber sleeve 8 contacts the inner wall of the mounting hole 13, it will be squeezed and deformed to squeeze into the interior of the mounting hole 13. When the arc-shaped rubber sleeve 8 then reaches the interior of the arc-shaped slot 14, it will recover and be snapped into the interior of the arc-shaped slot 14.

By opening the first cross slot 5 on the connecting rod 4 and the second cross slot 12 on the bolt 1, the two springs 6, the two connecting plates 7 and the cross clamping plate 10 can be used to complete the installation and disassembly of the bolt 1 without removing the protective cover 3, thereby improving the practicality of the anti-oxidation and corrosion-resistant bolts.

[0036] Furthermore, by setting the first cross slot 5, the second cross slot 12 and the hexagonal shape of the bolt head 1, when any one of the first cross slot 5, the second cross slot 12 and the hexagonal shape of the bolt head 1 is deformed and cannot be removed normally, the other two methods can be used to remove the bolt 1, further improving the practicality of the anti-oxidation and corrosion-resistant bolts.

[0037] Working principle: When using anti-oxidation and corrosion-resistant bolts, the user can first use a cross screwdriver or a flat-blade screwdriver to engage with the inside of the first cross slot 5, and press downward to move the connecting rod 4 downward, and make the cross clamping plate 10 engage with the inside of the second cross slot 12. After that, the user can twist the bolt 1 to fix it. By setting the protective cover 3, the exposed part of the bolt 1 after the fixation is completed is protected, and the influence of the external environment on the exposed part after the fixation of the bolt 1 is reduced. By opening the first cross slot 5 on the connecting rod 4 and the second cross slot 12 on the bolt 1, the two springs 6, the two connecting plates 7 and the cross clamping plate 10 can be used to complete the installation and removal of the bolt 1 without removing the protective cover 3.

[0038] Furthermore, by setting the first cross slot 5, the second cross slot 12 and the hexagonal shape of the bolt 1 head, when any one of the first cross slot 5, the second cross slot 12 and the hexagonal shape of the bolt 1 head is deformed and cannot be removed normally, the other two methods can be used to remove the bolt 1.
