Description

Rings formula locking spiro union component

Technical Field

The utility model relates to a locking spiro union component of rings formula.

Background

The nut is a nut, and is a part which is screwed together with a bolt or a bolt to play a role in fastening, and one element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and the like according to different materials.

In order to facilitate the disassembly of the threaded connection, the bolt and the nut need to have a tolerance of a movement range during design and manufacture so as to ensure that a gap exists between the nut and the bolt. Because the locking of screw thread is formed by the frictional force between the bolt tooth and the nut tooth, under the condition of light load and slight vibration, the relative movement between the nut and the bolt can not be generated, the frictional force between the bolt and the nut can be maintained, the bolt and the nut can not be loosened, however, under the condition of heavy load and serious vibration, particularly under the condition of alternating load and transverse vibration, the transverse movement between the bolt and the nut can be generated, so that the frictional force disappears, and the threaded connection is loosened.

In order to avoid loosening of the threaded connection and maintain the stability of the connection, people use various methods for fixing, most commonly, a gasket is used for locking a nut, or a double nut is used for generating a tightening torque between the two nuts to lock the threaded connection, and the two methods are simple and easy to implement, low in cost and poor in reliability. Therefore, how to realize the stability and reliability of the threaded connection structure and reduce the difficulty and cost of processing and manufacturing are technical problems to be solved urgently in the industry.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned technical problem that prior art exists, the utility model aims at providing a locking spiro union component of rings formula.

The hanging ring type anti-loosening threaded component comprises a nut body and a bolt in threaded fit with the nut body, and is characterized by further comprising two lifting lugs and two hanging rings, wherein the two lifting lugs and the two hanging rings are symmetrically and fixedly arranged on two sides of the nut body; when the two lifting rings are mutually inclined and are arranged in a crossed mode, the ring holes of the two lifting rings and the threaded hole in the center of the nut body can be overlapped in the vertical direction, and the bolt screwed on the nut body can be screwed to penetrate through the ring holes of the two lifting rings arranged in a crossed mode.

The hoisting ring type anti-loosening bolt connection component is characterized in that the nut body is a hexagon nut, threaded holes are formed in two opposite side faces of the nut body respectively, matched threaded holes are formed in the upper end of the lifting lug, and the lifting lug is fixed to the side face, provided with the threaded holes, of the nut body through the matched screws.

The hoisting ring type anti-loosening bolt connection component is characterized in that hoisting ring trepanning holes are formed in the positions, lower ends of the hoisting rings, of the lower surfaces of the nut bodies, and the hoisting rings are arranged in the hoisting ring trepanning holes of the hoisting rings in a matched mode.

The hoisting ring type anti-loosening bolt connecting component is characterized in that the thickness of the hoisting ring is smaller than the thread clearance of the bolt, so that the hoisting ring can be embedded into the thread clearance of the bolt.

Compared with the prior art, the beneficial effect that this application was got is:

the anti-loosening bolt joint component with the lifting ring is simple in structure and easy to process. When the bolt is fixedly connected with the nut body in a threaded manner, the bolt is firstly screwed with the nut body, then the bolt penetrates through the two hanging rings which are inclined in opposite directions and are arranged in a crossed manner, the two hanging rings are embedded into a thread tooth gap of the bolt, and the bolt has two tightening forces in opposite directions; the nut body is fastened with the bolt through the hanging ring and the lifting lug to form a whole, so that bolt loosening force generated during heavy load and severe vibration can be effectively offset.

Detailed Description

The present invention is further illustrated by the following examples, which should not be construed as limiting the scope of the invention.

Example (b): compare FIGS. 1-3

The utility model provides a locking spiro union component of rings formula, includes nut body 1 and with 1 screw-thread fit's of nut bolt, can see that nut body 1 has adopted ordinary hexagon nut, and the relative both sides face of hexagon nut is equipped with the screw hole respectively.

Two lugs 2 are fixedly arranged on two opposite sides of the nut body 1, and the lugs 2 are fixedly arranged on the side of the nut body 1: the upper end of the lifting lug 2 is also provided with a threaded hole, and the lifting lug 2 is fixed on the side surface of the nut body 1 provided with the threaded hole through a matched screw.

It can be seen that the lower ends of the lifting lugs 2 are all lower than the lower surface of the nut body 1, and the lifting rings 3 are installed at the positions of the lower ends of the lifting lugs 2 lower than the lower surface of the nut body 1. The mode that rings 3 are installed on lug 2 does: the lower end of the lifting lug 2 is lower than the lower surface of the nut body 1, a lifting ring sleeve hole is formed in the position, lower than the lower surface of the nut body 1, of the lifting lug 2, the lifting ring 3 is arranged in the lifting ring sleeve hole in a matched mode, and therefore the lifting ring 3 can rotate up and down on the lifting lug 2.

In this application, the thickness of rings 3 is less than the thread tooth clearance of bolt, because rings 3 thickness direction's cross-sectional area is little, can imbed among the thread tooth clearance of bolt, has played fixed locking effect.

In order to facilitate the two hanging rings 3 to be inserted into the thread tooth clearance of the bolt in a crossed manner, the lowest ends of the two hanging rings 3 are arranged in a mutually staggered manner in the height direction. For example, the lowermost end of one of the links 3 is 0.5-3cm lower than the lowermost end of the other link 3.

When the locking spiro union component of rings formula of this application was used, with two rings 3 slope and cross the placing in opposite directions, the annular ring of two rings 3 and the screw hole at nut body 1 center can overlap in vertical direction, and the bolt of spiro union on nut body 1 can be screwed and pass the annular ring of two rings 3 of cross the placing, and rings 3 can imbed among the thread tooth clearance of bolt. From this, lug 2 and rings 3 through the adaptation are passed through to nut body 1 both sides, have the tension of two opposite directions to the bolt, and the connection between bolt and the nut body 1 is comparatively firm.

The statements in this specification merely set forth a list of implementations of the inventive concept and the scope of the present invention should not be construed as limited to the particular forms set forth in the examples.
