BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is a structural schematic view of the utility model;

[0012] In the drawing: 1 nut body, 2 recess, 3 fixed slot, 4 through slot, 5 containing groove, 6 backing plate, 7 containing part, 8 spring. DETAILED DESCRIPTION

[0013] The technical scheme in the embodiments of the utility model will be clearly and completely described 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, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0014] As Figure 1 shown, a locking check nut, including nut body 1, the upper and lower end surface center of nut body is equipped with recess 2 downward, upward respectively, the fixed slot 3 of being equipped with through between the middle part of two recesses, the groove wall of fixed slot is equipped with thread, the vertical groove wall of recess is equipped with through slot 4 to the outside of nut body, the upper and lower end surface of nut body is also equipped with annular containing groove 5, the through slot passes through containing groove, one containing groove is inserted and is equipped with backing plate structure, the backing plate structure includes backing plate 6 and containing part 7, containing part inserts containing groove, spring 8 and limit plate (not shown in the drawing) are equipped in through slot, spring is against containing part, limit plate is against spring, the other end of limit plate is equipped with anti-skid line and protrudes in containing groove for being against external bolt piece.

[0015] Preferably, the through slot 4 is provided with at least four groups, which are uniformly distributed.

[0016] Further, the containing part 7 is also provided with a threaded hole, and a connecting piece is screwed in the threaded hole and abuts against the limit plate through the spring. Specifically, the connecting piece is a threaded rod, and a cross groove is formed in the outer side end surface of the threaded rod.

[0017] The working principle of the utility model is as follows: the backing plate is inserted into the containing groove, the spring and the limit plate are arranged, then the nut is connected to the external connecting piece, which can be a bolt, and after the nut is connected in place, the limit plate also abuts against the bolt, thereby increasing the connection stability; then, in order to further strengthen the connection stability, the threaded hole of the containing part is connected by the connecting piece, so that the connecting piece abuts against the limit plate, thereby ensuring the double-limiting stability of the limit plate under the cooperation of the spring, so as to ensure the stability of the nut connection.

[0018] 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.
