Description

nut

technical field

The utility model relates to the technical field of auto parts, more specifically, it relates to a nut.

Background technique

A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. However, when in use, the nut is directly stuck on the fixed part, but it is easy to loosen or fall off, and it is easy to loosen or fall off when it is fixed. At this time, the object is likely to collide with the bolt end and loosen easily.

Contents of the invention

In view of the deficiencies in the prior art, the purpose of the utility model is to provide a nut with high fixing and stable strength and not easy to loosen.

In order to achieve the above purpose, the utility model provides the following technical solutions: a nut, including a nut body, the nut body is in the shape of a hexagonal column, and a limit block is provided at one end of the nut body, and the limit block includes a first installation block and the second mounting block, the first mounting block and the second mounting block are in the shape of a circular platform, the largest diameter end face of the first mounting block is integrally connected with the largest diameter end face of the second mounting block, and the largest diameter of the first mounting block is The diameter end surface is the same size as the maximum diameter end surface of the second mounting block, a bulge is formed at the connecting end of the first mounting block and the second mounting block, and a threaded hole is provided on the nut body, and the threaded holes pass through the nut body in turn and the first mounting block into the second mounting block, the other end face of the connecting end face of the nut body and the limiting block is provided with a first notch, and the connecting end face of the nut body and the limiting block is respectively provided with the first gap. The second notch opposite the notch.

By adopting the above technical scheme, the nut body is in the shape of a hexagonal column, so that it is the same as the traditional nut, and one end of the nut body is provided with a limit block, and the limit block includes a first mounting block and a second mounting block, and the first mounting block Both the second mounting block and the second mounting block are in the shape of a circular platform, and the largest diameter end face of the first mounting block is integrally connected with the largest diameter end face of the second mounting block. The largest diameter end face of the first mounting block and the largest diameter end face of the second mounting block are the same in size. A bulge is formed at the connecting end of the first mounting block and the second mounting block, which facilitates insertion into the workpiece through the small end face, and connects the large-area end of the first mounting block with the large-area end of the second mounting block to form a joint. The bulge can play a good limit effect, making it more stable when fixed, and it is not easy to fall off and loosen, and the nut body is provided with a threaded hole, and the threaded hole runs through the nut body and the first mounting block to the second mounting block in turn. In the second installation block, when the bolt is tightened, it can be directly inserted into the limit block to protect the screw. When moving, the nut body and the bolt can move together, and there will be no single movement, so it is very good. The stability of use is ensured, and it is not easy to loosen. The other end face of the nut body and the limit block is provided with a first gap, and the nut body and the limit block are respectively provided with a first notch on the end face of the connection end. The second notch opposite to the notch, through the design of the first notch and the second notch on the top and bottom of the nut body, can make the first notch and the second notch weaken the force generated by the screw when the force is applied. As a result, the transmitted force can be weakened to a certain extent, so as to improve the overall bearing capacity.

detailed description

The embodiment of the utility model will be further described with reference to Fig. 1 to Fig. 2 .

A nut, comprising a nut body 101, the nut body 101 is in the shape of a hexagonal column, and one end of the nut body 101 is provided with a limiting block, and the limiting block includes a first mounting block 301 and a second mounting block 401, the Both the first mounting block 301 and the second mounting block 401 are in the shape of a circular frustum, and the largest diameter end face of the first mounting block 301 is integrally connected with the largest diameter end face of the second mounting block 401, and the largest diameter end face of the first mounting block 301 is connected to the second mounting block 401. The maximum diameter end faces of the two mounting blocks 401 have the same size, a bulge 501 is formed at the connecting end of the first mounting block 301 and the second mounting block 401, and a threaded hole 201 is provided on the nut body 101, and the threaded holes 201 are in turn Through the nut body 101 and the first mounting block 301 to the second mounting block 401, a first notch 102 is provided on the other end face of the connecting end face of the nut body 101 and the limiting block, and the nut body 101 and the limiting block Second notches 103 opposite to the first notches 102 are provided on the connecting end surface.

By adopting the above-mentioned technical scheme, the nut body 101 is in the shape of a hexagonal column, so that it is the same as a traditional nut, and one end of the nut body 101 is provided with a limit block, and the limit block includes a first mounting block 301 and a second mounting block 401, the The first mounting block 301 and the second mounting block 401 are all in the shape of a circular frustum, and the largest diameter end face of the first mounting block 301 is integrally connected with the largest diameter end face of the second mounting block 401, and the largest diameter end face of the first mounting block 301 is connected to the second mounting block.
