Description

Anti-disassembly nut assembly

Technical Field

The utility model relates to the technical field of nuts, in particular to an anti-disassembly nut assembly.

Background

The nut is a part screwed with a bolt or a screw rod to play a fastening role, and the nut is a part for tightly connecting mechanical equipment and locks the bolt through an inner thread. The nut is a standard component in common use, however, in order to prevent the nut from being disassembled at will, the nut is improved in the prior art, so that the risk of being disassembled at will is reduced. For example, CN109026972a discloses a tamper-proof nut, in which an elastic member is provided in the groove to push the column. Because the nut size itself is less, the degree of difficulty of installation elastic component and cylinder is great, and processing cost is higher. In addition, the complex structure of the nut can lead to reduced processing efficiency, which is unfavorable for mass production.

Detailed Description

The essential features and advantages of the utility model will be further elucidated with reference to the examples, without however being limited to the embodiments listed.

As shown in fig. 1 to 4, the anti-disassembly nut assembly of the embodiment comprises a main body 1, wherein the main body 1 is cylindrical, a threaded hole 2 is formed in the middle of the main body 1, a first end face 11 and a second end face 12 are respectively formed in two sides of the main body 1, the threaded hole 2 penetrates through the first end face 11 and the second end face 12, and therefore a bolt 10 can be connected with the main body 1 through the threaded hole 2 in a threaded mode. The first end face 11 is provided with positioning holes 13, and a plurality of positioning holes 13 are arranged at intervals. The main part 1 top is equipped with apron 3, and apron 3 is circular, and apron 3 has first plane 31 and the second plane 32 of relative setting, second plane 32 is equipped with reference column 33, and reference column 33 one end is connected with second plane 32, and the other end is the free end, and reference column 33 corresponds setting with locating hole 13. In the above technical solution, when the bolt 10 needs to be locked, the main body 1 is placed into the mounting hole 201 of the workpiece 20 and is screwed with the bolt 10, and when the main body 1 is locked, the main body 1 is driven to rotate by inserting the specially-made external workpiece into the positioning hole 13 and then rotating. By the cover plate 3, the mounting hole 201 can be closed so that the upper end of the work piece 20 can be kept flush. When the cover plate 3 is mounted, the positioning posts 33 are inserted into the positioning holes 13 to support, so that the cover plate 3 is prevented from being pressed into the mounting holes 201. According to the technical scheme, the main body is difficult to detach by the existing tools such as a spanner and the like by changing the structure of the main body, so that the risk of detaching the main body can be reduced; meanwhile, the mounting holes can be sealed, and the service life of the main body is prolonged.

In this embodiment, the first end face 11 is a conical surface, and the second end face 12 is a flat surface, so that the main body is more difficult to be disassembled by a non-matching tool. Between the first end face 11 and the second end face 12 is a side face 14, and the side face 14 is a smooth plane, so that the main body 1 can be conveniently rotated into the mounting hole. The side edge of the cover plate 3 is provided with extending parts 34, a plurality of extending parts 34 are arranged at intervals, the extending parts 34 extend downwards from the second plane 32 of the cover plate, the extending parts 34 have elastic deformation capability, and the extending parts 34 can be clamped into the mounting holes 201, so that the cover plate 3 is mounted more firmly. The extending portion 34 is semicircular, and two positioning posts and two extending portions are respectively arranged in the embodiment. The first plane 31 is provided with an indication part 4, and the position of the indication part corresponds to the positioning column 33, so that the direction of the positioning column can be rapidly judged. The indication part 4 is a triangular groove, so that the cover plate can be taken out by inserting a customizing tool into the triangular groove, and the cover plate can be taken out conveniently by arranging magnetic materials in the triangular groove. The length of the positioning post 33 is longer than the length of the extension 34, so that the extension 34 is prevented from interfering with the main body 1 when the mounting hole 201 is fitted.

The anti-disassembly nut component is difficult to disassemble by the existing tools such as a spanner, so that the risk of disassembling the main body can be reduced; meanwhile, the mounting holes can be sealed, and the service life of the main body is prolonged.

It should be noted that the foregoing description of the preferred embodiments is merely illustrative of the technical concept and features of the present utility model, and is not intended to limit the scope of the utility model, as long as the scope of the utility model is defined by the claims and their equivalents. All equivalent changes or modifications made in accordance with the spirit of the present utility model should be construed to be included in the scope of the present utility model.
