Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to an anti-rust bolt. Background Art

[0002] Bolt: A mechanical part, a cylindrical threaded fastener equipped with a nut. It is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut and is used to fasten two parts with through holes. This type of connection is called a bolt connection. When the bolt is in use, it is necessary to prevent rust on the bolt.

[0003] After searching, the Chinese patent with the publication number of "CN219911440U discloses a rust-proof bolt, including a bolt body, the interior of the bolt body is provided with an anti-rust structure, the anti-rust structure includes a rotating block, a pressing block, a hollow column and a sponge strip, and the exterior of the rotating block is processed with an external thread. The pressing block is driven down by the rotating block in the anti-rust structure, and the pressing block squeezes the sponge strip, and the lubricating oil in the sponge strip is poured into the hollow column. The lubricating oil in the hollow column enters the interior of the bolt body through the oil outlet groove and the oil outlet hole, and then flows to the exterior of the bolt body through the through hole. A periodic de-compression of the lubricating oil in the sponge strip is arranged to form a protective film on the surface of the bolt body, the bolt body will not react with moisture and oxygen in the air, and will not rust, and it becomes convenient to rotate the bolt body." However, the prior art has the following shortcomings when used:

[0004] The rotating block is threadedly connected to the bolt body. The pressing block is driven down by rotating the rotating block, and the pressing block squeezes the sponge strip to squeeze out the lubricating oil in the sponge strip. This method is more troublesome in actual operation, and it is necessary to rotate the rotating block for a long time to make the pressing block slowly move down to squeeze the sponge strip, which is time-consuming and labor-intensive and has low practicality.

[0005] Therefore, a kind of rust-proof bolt is needed to solve the above problems. Utility Model Content

[0030] Example:

[0031] like Figure 1-5 As shown, an anti-rust bolt proposed in this embodiment includes a bolt body 1, which includes a hexagonal bolt head 2 and a bolt rod 3. The hexagonal bolt head 2 is provided with a mounting through hole 4, in which a connecting block 5 is provided. The connecting block 5 is pressed, and a pressing block 6 is fixedly connected to the bottom of the connecting block 5. The hexagonal bolt head 2 is provided with symmetrically distributed sliding grooves 7, in which a spring 8 is provided. The spring 8 is compressed and deformed when subjected to force. A slider 9 is fixedly connected to the top of the spring 8. The connecting block 5 is fixedly connected to the slider 9, so that the connecting block 5 and the pressing block 6 move downward with the slider 9. The bolt rod 3 is provided with a placement groove 10, in which a sponge block 11 soaked in lubricating oil is provided. The sponge block 11 is squeezed by the downwardly moving pressing block 6 to squeeze out the lubricating oil in the sponge block 11.

[0032] like Figure 1 and Figure 5 As shown, the bolt rod 3 is provided with a plurality of evenly arranged oil outlet holes 12, which are connected to the placement groove 10. The lubricating oil flows to the outside of the bolt rod 3 through the plurality of oil outlet holes 12, forming a protective film on the surface of the bolt rod 3 to prevent the surface of the bolt rod 3 from rusting.

[0033] like Figure 1 As shown, a gasket 13 sleeved on the outside of the bolt rod 3 is fixedly connected to the bottom of the hexagonal bolt head 2. The gasket 13 can further prevent the bolt rod 3 from reacting with moisture and oxygen in the air when the hexagonal bolt head 2 is tightened.

[0034] like Figure 2 and Figure 4 As shown, one end of the spring 8 away from the slider 9 is fixedly connected to the inner bottom wall of the slide groove 7, the slide groove 7 is connected to the mounting through hole 4, and the slider 9 is driven to move by the spring 8.

[0035] like Figure 2 and Figure 5 As shown, the placement groove 10 is adapted to the size of the sponge block 11 .

[0036] Specifically, when the present rust-proof bolt is in use: by pressing the connecting block 5, the spring 8 is subjected to force to produce compression deformation, so that the connecting block 5 and the pressing block 6 move downward with the slider 9, and the sponge block 11 is squeezed by the downwardly moving pressing block 6 to squeeze the lubricating oil in the sponge block 11, and the lubricating oil flows to the outside of the bolt rod 3 through multiple oil outlet holes 12, forming a protective film on the surface of the bolt rod 3 to prevent the surface of the bolt rod 3 from rusting. The operation is simple, time-saving and labor-saving. When the connecting block 5 is not pressed, the elastic force of the spring 8 causes the connecting block 5 and the pressing block 6 to move upward with the slider 9.

[0037] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
