Description

Technical Field

[0001] This utility model relates to a valve plate, and more particularly to a valve plate for improving the anti-loosening performance of nuts. Background Technology

[0002] Currently, the washers or valve plates used for nuts are all straight plates. Due to the limitations of their shape, these straight plates cannot generate elasticity during use. As a result, the spring plate can only act as a baffle and cannot affect the anti-loosening performance of the nut during use. Therefore, its function is relatively simple. Utility Model Content

[0003] This invention provides a valve plate for improving the anti-loosening performance of nuts, which can effectively improve the anti-loosening performance of nuts during use.

[0004] The present invention adopts the following technical solution: a valve plate for improving the anti-loosening performance of nuts, comprising a valve plate body, the valve plate body being an annular elastic plate, the annular elastic plate being recessed inward and inclined, the inclination angle of the annular elastic plate being opposite to the inclination angle of the protruding inclined portion of the nut end face.

[0005] Furthermore, the annular elastic sheet of this utility model is a 201 stainless steel sheet or a 301 stainless steel sheet.

[0006] Furthermore, the inward inclination angle of the annular elastic sheet body of this utility model is 10°, and the inclination angle of the protruding inclined portion is 10°.

[0007] Furthermore, the upper and lower parts of the inner ring of the annular elastic sheet of this utility model are respectively provided with an upper fan-shaped annular baffle and a lower fan-shaped annular baffle, which together form a bolt insertion hole.

[0008] Furthermore, the bottom surface of the upper annular baffle and the top surface of the lower annular baffle of the bolt insertion hole of this utility model are both provided with threads, and the thread shape of the threads corresponds to the thread shape of the bolt.

[0009] This utility model has the following beneficial effects: After adopting the above technical solution, the main body of the valve plate of this utility model is an annular elastic plate. The annular elastic plate is concave inward and inclined. Since the annular elastic plate is inclined and has good elasticity, after being squeezed between the nut and the connecting workpiece, the length of the annular elastic plate is stretched and unfolded, so that the annular elastic plate can cover the protruding part of the end face of the nut and can also tightly lock the annular elastic plate in the gap between the nut and the connecting workpiece, so that there is no space for loosening between the nut and the connecting workpiece, effectively preventing the nut from loosening and improving the anti-loosening performance of the nut during use. At the same time, the bolt and the thread in the bolt insertion hole cooperate to further prevent the bolt and nut from loosening. Attached Figure Description

[0014] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0015] exist Figure 1 , Figure 2 and Figure 3This utility model provides a valve plate for improving the anti-loosening performance of nuts. It includes a valve plate body, which is an annular elastic plate 1. The annular elastic plate 1 is concave and inclined, with the inclination angle of the concave portion opposite to the inclination angle of the protruding inclined portion 8 on the end face of the nut 6. In this embodiment, the annular elastic plate 1 is made of 201 stainless steel or 301 stainless steel, with 301 stainless steel being preferred. The inclination angle of the concave portion of the annular elastic plate 1 in this embodiment is 10°, and the inclination angle of the protruding inclined portion 8 is also 10°. The annular elastic plate 1 has an upper fan-shaped annular baffle 2 and a lower fan-shaped annular baffle 3 on its upper and lower inner rings, respectively.

[0016] The upper annular baffle 2 and the lower annular baffle 3 are combined to form a bolt insertion hole 4. In this embodiment, the bottom surface of the upper annular baffle 2 and the top surface of the lower annular baffle 3 of the bolt insertion hole 4 are both provided with threads 5, and the thread shape of the threads 5 is opposite to the thread shape of the bolt.

[0017] The method of using this utility model is as follows: The bolt is inserted into the nut 6 to connect with the connecting workpiece 7. The annular elastic plate 1 is placed between the nut 6 and the connecting workpiece 7. When the bolt is tightened, the nut 6 squeezes the annular elastic plate 1. Since the annular elastic plate 1 is concave and inclined, and since the annular elastic plate 1 is inclined and has good elasticity, after being squeezed between the nut 6 and the connecting workpiece 7, the length of the annular elastic plate 1 is stretched and unfolded. The concave annular elastic plate 1 covers the protruding inclined part 8 of the end face of the nut 6, thus tightly locking the annular elastic plate 1 in the gap between the nut 6 and the connecting workpiece 7, so that there is no space for loosening between the nut 6 and the connecting workpiece 7, effectively preventing the nut 6 from loosening. When the bolt is turned, the bolt is also inserted into the bolt insertion hole 4. After the bolt thread matches the thread of the bolt insertion hole 4, the bolt is also locked in the bolt insertion hole 4, so that the bolt will not loosen in the nut 6.

[0018] However, this is not the only possibility. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
