BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 It is the structural schematic diagram of the utility model.

[0010] In the figure, 1, nut main body; 2, nut body one; 3, nut body two; 4, sliding ring; 5, reset spring; 6, rolling ball; 7, rolling groove; 8, clamping groove one; 9, clamping groove two. Specific embodiments

[0011] The following is the specific embodiment of the utility model and further describes the technical scheme of the utility model in conjunction with the drawings, but the utility model is not limited to these embodiments.

[0012] As Figure 1 Indicated, the self-adapting regulation nut assembly, including nut main body 1, the nut main body 1 by nut body one 2 and nut body two 3 are composed, the nut body two 3 is provided with the thread that is in accord with bolt, the upper and lower ends of the nut body one 2 are all set up with the slot, the nut body one 2 and be located at the slot are all provided with sliding ring 4, and the sliding ring 4 can be on the nut body one 2 and slide up and down, the slot is provided with reset spring 5 for the sliding ring 4 and slides up and down, the nut body one 2 and be located at the position of sliding ring 4 are provided with rolling ball 6, and the nut body one 2 is set up with the rolling groove 7 for the rolling ball 6 and rolls, the inner wall of the sliding ring 4 is set up with the clamping groove one 8 that is matched with the rolling ball 6, the outer wall of the nut body two 3 is set up with the clamping groove two 9 that is matched with the rolling ball 6.

[0013] Further, when installing the nut body two 3, by depressing the sliding ring 4, make it move down, one end of the rolling ball 6 can extend into the clamping groove one 8 on the sliding ring 4, the reset spring 5 is in compression, that is, the nut body two 3 can be installed on the nut body one 2, then the reset spring 5 rebounds, the sliding ring 4 moves up, one end of the rolling ball 6 abuts against the inner wall of the sliding ring 4, and the other end of the rolling ball 6 extends into the clamping groove two 9 of the nut body two 3, so as to fix the nut body two 3 on the nut body one 2.

[0014] Further, since the nut body two 3 and the nut body one 2 are of split structure, the nut body two 3 of different sizes can be applied to bolts of different sizes.

[0015] Further, one end of the reset spring 5 is connected to the sliding ring 4, and the other end of the reset spring 5 is connected to the bottom wall of the slot.

[0016] Further, the sliding ring 4 is two, and is arranged on the upper and lower ends of the nut body 2. The ball 6 arranged on the upper and lower ends is clamped in the clamping groove 9 of the nut body 3 through the sliding ring 4, thereby enhancing the stability of the nut body 3 fixed on the nut body 2.

[0017] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0018] Although the terms such as nut body 1, nut body 2, nut body 3, sliding ring 4, return spring 5, ball 6, rolling groove 7, clamping groove 1 8, clamping groove 9 are used more in the text, but the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the present application; any additional limitation is contrary to the spirit of the present application.
