Description

Technical Field

[0001] The utility model belongs to the technical field of nuts and relates to a combined nut assembly. Background Art

[0002] A nut is a nut that is screwed together with a bolt or a screw to fasten. It is a component that all manufacturing machinery must use. According to the different materials, it is divided into several types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper). Existing nuts are divided into round nuts and polygonal nuts, so their disassembly is generally carried out with a wrench. The wrench is more convenient for the disassembly of polygonal nuts, but for the disassembly of round nuts, the round nuts need to be clamped, which will damage the wall of the round nuts, and in serious cases, may cause damage to the nuts. Summary of the invention

[0003] The purpose of the utility model is to provide a nut assembly that is easy to disassemble in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a combined nut assembly, including a nut body, characterized in that a disassembly unit connected to the nut body and convenient for disassembly is sleeved on the nut body, and a convex ring portion protruding radially outward and used to limit the position of the disassembly unit is provided on the outer peripheral wall of the nut body at one end.

[0005] In the above-mentioned combined nut assembly, the disassembly unit is composed of an outer ring, an inner ring and a plurality of rolling bodies. The inner ring is sleeved on the nut body and connected thereto. One end face of the inner ring is provided with a plurality of assembly holes arranged along its circumferential direction and for corresponding rolling bodies to be inserted and installed. The other end face of the inner ring is provided with an annular notch groove for exposing the rolling body to the outside. The height of the annular notch groove is smaller than the height of the inner ring. An open groove is provided on one end face of the inner ring located at the assembly hole for the rolling body to fit with the nut body. The outer ring is sleeved on the inner ring and fixedly connected thereto. The inner wall of the outer ring is in conflict with the rolling body.

[0006] In the above-mentioned combined nut assembly, a handle portion connected to the outer ring and facilitating the rotation of the outer ring is provided on the outer wall of the outer ring, and a limit cover connected to the outer ring and wrapping the rolling body therein is provided on one end face of the outer ring to limit the rolling body.

[0007] Compared with the prior art, the combined nut assembly has the following advantages:

[0008] 1. A disassembly unit connected to the nut body is sleeved on the nut body for facilitating its disassembly. A convex ring portion protruding radially outward and used to limit the position of the disassembly unit is provided on the outer peripheral wall of the nut body at one end. The above structure is arranged to facilitate its disassembly and reduce damage to the nut. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the combined nut assembly includes a nut body 1, which is a circular nut. A disassembly unit connected to the nut body 1 and convenient for disassembly is sleeved on the nut body 1. A convex ring portion 2 is provided on the outer peripheral wall of the nut body 1 at one end, which protrudes radially outward and is used to limit the position of the disassembly unit. The disassembly unit consists of an outer ring 3, an inner ring 4 and a plurality of rolling bodies 5. The inner ring 4 is sleeved on the nut body 1 and connected to the nut body 1. A plurality of assembly holes 6 are provided on one end face of the inner ring 4 along its circumferential direction and for corresponding rolling bodies 5 to extend into and install. The height of the assembly hole 6 is less than the height of the inner ring 4. A ring portion 2 is provided on the other end face of the inner ring 4 to partially expose the rolling body 5 to the outside. shaped notch groove, the height of the annular notch groove is smaller than the height of the inner ring 4, and an open groove is provided on one end face of the inner ring 4 located at the assembly hole 6 to make the rolling element 5 fit with the nut body 1, and the inner wall of the assembly hole 6 is made into a U-shaped structure with an arc shape through the open groove, and a plurality of interference parts that can interfere with the nut body 1 are formed through the open groove, and a gap is left between the inner ring 4 and the nut through the rolling element 5. When the inner ring 4 rotates, the interference part of the inner ring 4 will fit and interfere with the nut body 1, thereby realizing the disassembly of the nut body 1, and the outer ring 3 is sleeved on the inner ring 4 and fixedly connected thereto, and the inner wall of the outer ring 3 interferes with the rolling element 5, and the outer ring 3 is arranged at the annular notch groove.

[0014] To elaborate further, in order to facilitate its disassembly, a handle portion 7 connected to the outer ring 3 and facilitating the rotation of the outer ring 3 is provided on the outer wall of the outer ring 3. The handle portion 7 can be integrally provided with the outer ring 3 or separately provided. A limit cover 8 connected to the outer ring 3 and wrapping the rolling body 5 therein is provided on one end face of the outer ring 3, which limits the rolling body 5. The limit cover 8 can also be connected to the handle portion 7 in the outer ring 3, and the limit cover 8 and the outer ring 3 can be connected by threads.

[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0016] Although this article uses more terms such as 1. nut body; 2. convex ring; 3. outer ring; 4. inner ring; 5. rolling element; 6. assembly hole; 7. handle; 8. limit cover, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
