Description

High-stability bolt and nut assembly

Technical Field

The utility model belongs to the technical field of the bolt and nut subassembly, concretely relates to bolt and nut subassembly of high stability.

Background

The bolt is a mechanical part, a cylindrical threaded fastener matched with a nut, a fastener composed of a head part and a screw rod needs to be matched with the nut and is used for fastening and connecting two parts with through holes, the connection form is called bolt connection, if the nut is screwed off from the bolt, the two parts can be separated, and therefore the bolt connection belongs to detachable connection; the nut is a nut and is screwed together with a bolt or a screw rod to play a role in fastening, and an element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel, nonferrous metal and other types according to different materials;

the bolt and nut assembly is matched for use, when the two parts are fastened, the fastening stability is not good enough, and the fastened parts cannot be well limited, positioned and fixed.

Therefore, we propose a bolt-nut assembly which can stably fasten and fix two parts and has high stability and good fastening effect on the parts to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bolt and nut subassembly of high stability to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high stable bolt-nut subassembly, includes that bolt body and spiro union are fixed at the first nut and the second nut at bolt body front and back both ends, bolt body includes the dead lever, fixed first spacing ring of locating dead lever front end lateral surface, fixed second spacing ring of locating dead lever rear end lateral surface, fixed first spacing post of locating the dead lever front side and being located first spacing ring leading flank, fixed second spacing post of locating the dead lever rear side and being located second spacing ring trailing flank, fixed first external screw rod of locating first spacing post leading flank and fixed with first nut spiro union and fixed second external screw rod of locating second spacing post trailing flank and fixed with the second nut spiro union.

Preferably, the fixing rod, the first limiting column and the second limiting column are smooth round rods.

Preferably, a circular positioning block is arranged on the rear side face of the second outer threaded rod.

Preferably, the first nut is a hexagon nut with a sealed semicircular fixing cap fixedly arranged on the front side surface.

Preferably, the second nut is a right hexagonal nut.

The utility model discloses a technological effect and advantage: this high stable bolt-nut subassembly, cup joint the lateral surface at first spacing post and the spacing post of second respectively with two parts of area fastening, and the medial extremity of two parts carries on spacingly through first spacing ring and second spacing ring respectively, the outer end of two parts carries on spacingly through the first nut with first external screw thread pole spiro union and with the second nut of second external screw thread pole spiro union respectively, first nut is rotatory to the semi-circular fixed cap of canned type and supports the top with first external screw thread pole outer end, the second nut is rotatory to with the outer looks parallel and level of circular locating piece, can be stable fasten fixedly two parts, it is fixed just spacing effectual to the part fastening.
