Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped nuts, in particular to a rust-proof special-shaped nut. Background Art

[0002] Special shaped nuts are specially designed nuts, which are different in shape and structure from ordinary nuts and are usually used in special applications or when specific functions are required.

[0003] Publication No. CN216306445U discloses a special-shaped nut, which relates to the field of mechanical technology. It includes a hexagonal prism and an auxiliary component arranged on the outside of the hexagonal prism, a through hole is opened in the middle part of the hexagonal prism, and the auxiliary component includes an outer frame, which is a hollow design and is arranged on the outside of the hexagonal prism. The top of the hexagonal prism is penetrated by a plug rod, and a cylinder is arranged at the position of the middle through hole of the hexagonal prism. A thrust component is arranged on the inner side of the outer frame, and the thrust component includes a fixing plate. Through the provided plug rod and thrust component, after the special-shaped nut is used for a long time, although the plug rod will inevitably wear out, under the action of the thrust component, a downward thrust can be applied to the plug rod, so that the plug rod can always remain connected to the bolt, thereby avoiding the problem that the thread of the conventional nut is worn after long-term use, resulting in the fixed object no longer being tightened. Although this type of special-shaped nut can prevent the loosening of fixed objects due to thread wear, it is lacking in anti-corrosion. Since this type of special-shaped nut does not have an anti-corrosion structure, the nut and the bolt will rust when they are exposed to the air for a long time, making it difficult to disassemble the nut. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a rust-proof special-shaped nut, comprising a nut body, a column fixedly installed on the surface of the nut body, a cover plate provided on the top surface of the column, a sleeve fixedly installed on the surface of the cover plate, a sliding groove provided on the surface of the column, a sliding rod slidably connected inside the nut body, a spring sleeved on the surface of the sliding rod, an inner slide fixedly installed on the surface of the slide rod, and an outer slide fixedly installed on the surface of the inner slide.

[0006] Preferably, a limiting groove is provided on the surface of the nut body, a limiting rod is slidably connected inside the limiting groove, a fixing plate is fixedly mounted on the surface of the limiting rod, and a soft pad A and a soft pad B are fixedly mounted on the surface of the fixing plate. Here, the design of the limiting groove and the limiting rod has the effect of limiting the fixing plate.

[0007] Preferably, one end of the spring is connected to the surface of the inner slide plate, and the other end is connected to the inner surface of the nut body. Here, the design of the spring plays an effect of driving the inner slide plate to slide in the slide groove.

[0008] Preferably, the inner slide plate is slidably connected to the slide groove, and the outer slide plate is slidably connected to the column. Here, the sliding design of the inner slide plate and the outer slide plate enables the cover plate and the sleeve to be adapted to bolts of different lengths.

[0009] Preferably, the sleeve is slidably connected to the outer slide plate. Here, the sliding design of the sleeve and the outer slide plate facilitates the sealing of the nut body, thereby avoiding the situation where the nut body is exposed and corroded.

[0010] Preferably, the soft pad A and the soft pad B are made of natural rubber. Here, the natural rubber material design of the soft pad A and the soft pad B serves to increase the sealing effect of the connection between the nut body and the installation object when the nut body is installed.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, the cover plate, sleeve, slide bar, spring, inner slide plate and outer slide plate are provided to facilitate sealing of the nut body and the bolt, and also facilitate installation of bolts of different lengths, thereby preventing the nut body and the bolt from being corroded and difficult to disassemble, and the structure is simple and practical.

[0026] Embodiment 2

[0027] See also Figure 1-6 A limiting groove 10 is provided on the surface of the nut body 1, and a limiting rod 11 is slidably connected inside the limiting groove 10. The design of the limiting groove 10 and the limiting rod 11 has the effect of limiting the fixing plate 12. The fixing plate 12 is fixedly installed on the surface of the limiting rod 11, and the surface of the fixing plate 12 has soft pads A13 and soft pads B14 fixedly installed. The material of the soft pads A13 and soft pads B14 are both natural rubber. The design of the natural rubber material of the soft pads A13 and soft pads B14 increases the sealing effect of the connection between the nut body 1 and the installation object when the nut body 1 is installed.

[0028] Working principle: when the nut body 1 needs to be installed, it is only necessary to connect the bolt and the nut body 1 through threads. After the nut body 1 is connected, the cover plate 2 is connected to the bolt through threads. At this time, the cover plate 2 will drive the sleeve 3 to slide on the surface of the outer slide plate 7, thereby driving the outer slide plate 7 to slide on the surface of the column 4, and at the same time, it will also drive the inner slide plate 6 to slide inside the slide groove 5. At this time, the inner slide plate 6 will also drive the slide rod 8 to slide inside the nut body 1, and the inner slide plate 6 will also be pushed upward by the elastic force of the spring 9. After the cover plate 2 is connected, the sealing of the nut body 1 can be completed. The cover plate 2, sleeve 3, slide rod 8, spring 9, inner slide plate 6 and outer slide plate 7 facilitate the sealing of the nut body 1 and the bolt. The invention also makes it easy to install bolts of different lengths, thereby preventing the nut body 1 and the bolt from being corroded and difficult to disassemble. When installing the nut body 1, the nut body 1 and the installation object will squeeze the fixing plate 12. When being squeezed, the fixing plate 12 will drive the limiting rod 11 to slide into the limiting groove 10 until the soft pad A13 and the soft pad B14 are tightly attached to the surfaces of the installation object and the nut body 1. The limiting rod 11, the fixing plate 12, the soft pad A13 and the soft pad B14 increase the sealing effect of the connection between the nut body 1 and the installation object when the nut body 1 is installed, thereby preventing moisture in the air from entering the interior of the nut body 1 and causing the nut body 1 to be corroded.
