SUMMARY

[0003] The utility model discloses to the deficiency in the above background technology, provide an improved anti-loose nut that improves the stability of nut connection and guarantees the anti-loose performance of nut.

[0004] In order to realize the above-mentioned purpose, the utility model discloses an improved anti-loose nut adopts the following technical scheme:

[0005] An improved anti-loose nut, including main nut and vice nut, the upper and lower end faces of main nut are provided with recess respectively downwards and upwards, and the recesses are communicated between the middle parts, and the communication place is provided with a threaded hole formed by a thread, the side wall of threaded hole is provided with the first fixed slot of vertical arrangement, the edge of recess is provided with the second fixed slot to another recess direction, the first fixed slot is provided with the limit plate, the one end surface of vice nut is provided with the adjusting plate for limiting limit plate, the adjusting plate is clamped into the second fixed slot, and the limit plate is resisted.

[0006] The further improvement of the utility model discloses an improved anti-loose nut lies in that the first fixed slot is provided with four groups, and is evenly distributed.

[0007] The further improvement of the utility model discloses an improved anti-loose nut lies in that the adjusting plate is cylindrical plate.

[0008] The further improvement of the utility model discloses an improved anti-loose nut lies in that the side face of limit plate away from adjusting plate is provided with reverse thread.

[0009] Compared with the prior art, the utility model has the advantages of:

[0010] The utility model realizes the further limiting of bolt connection through two groups of nuts and limit plates, prevents the loose and loose phenomenon, improves the connection stability performance, on the other hand, the relative stable connection of two groups of nuts is realized by the clamping of adjusting plate and limit plate, and the fastening performance of bolt connection is also improved by the use of two groups of nuts. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1The utility model discloses a structure schematic drawing of the utility model;

[0012] Figure 2 The utility model discloses a top structure schematic drawing of the utility model main nut;

[0013] In the drawing: 1 main nut, 2 auxiliary nut, 3 recess, 4 threaded hole, 5 first fixed groove, 6 second fixed groove, 7 limiting plate, 8 adjusting plate. DETAILED DESCRIPTION

[0014] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work fall within the protection scope of the utility model.

[0015] As Figure 1 And Figure 2 As shown in the figure, an improved anti-loose nut, comprising main nut 1 and auxiliary nut 2, the upper and lower end faces of the main nut are respectively provided with recesses 3 downward and upward, the two recesses are communicated between the middle parts, the communication part is provided with a threaded hole 4 formed by a thread, the side wall of the threaded hole is provided with a first fixed groove 5 arranged vertically, the edge of the recess is provided with a second fixed groove 6 in the direction of the other recess, the first fixed groove is provided with a limiting plate 7, the end face of the auxiliary nut is provided with an adjusting plate 8 for limiting the limiting plate, the adjusting plate is clamped into the second fixed groove 6 and abuts against the limiting plate 7, and the limiting plate is used for abutting against the bolt. The side face of the limiting plate away from the adjusting plate is provided with a reverse thread. The reverse thread abuts against the bolt to realize anti-loose. Preferably, the first fixed groove is provided with four groups and is uniformly distributed. Furthermore, the limiting plate is also provided with four groups. Specifically, the adjusting plate is a cylindrical plate.

[0016] The working principle of the utility model is as follows: after connecting the main nut with the bolt, the limiting part is arranged, then the auxiliary nut is connected, the adjusting plate on the auxiliary nut is inserted into the second fixed groove, at this time, the inner plate of the adjusting plate abuts against the limiting plate, and the reverse thread on the other side face of the limiting plate abuts against the bolt to realize stable limiting. Overall, the two groups of nuts cooperate with the adjusting plate and the limiting plate to realize stable limiting connection of the nut and the bolt.

[0017] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
