Description

Locking cut-in bolt structure that moves

Technical Field

The utility model relates to a bolt structure especially relates to an anti-loosening cut-in bolt structure.

Background

As is known, a bolt is a mechanical part, which is a cylindrical threaded fastener used for matching a nut, and the fastener is composed of a head and a screw (a cylinder with external threads), and needs to be matched with the nut for fastening and connecting two parts with through holes; the application range of the bolt is wide, and the bolt is unnecessary or unnecessary in daily life and industrial production and manufacturing. Along with the development of society, the application range of the anti-loosening bolt is wider and wider, the anti-loosening bolt is used in places where high-speed rails, ships, engines and the like cause vibration, and the anti-loosening bolt used at present is complex in manufacturing process and high in price and cannot be popularized in a large range.

Disclosure of Invention

In order to overcome the not enough in the background art, the utility model discloses a locking cut-in bolt structure that moves.

In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides an anti-loosening cut-in bolt structure, includes lock nut, by fastener and bolt body, the one end of bolt body is worn to establish in the screw hole by the fastener, through lock nut fastening, installs the gasket on lock nut and by the bolt body between the fastener, is provided with at least one and gasket vertically along the gasket inner ring surface and cuts in the piece, it sets up as an organic whole with the gasket to cut in the piece.

The anti-loosening cut-in type bolt structure is characterized in that the upper end part of the cut-in piece is in a sharp-horn shape.

The anti-loosening cut-in type bolt structure is characterized in that the thickness of the cut-in sheet is suitable for being cut into the space between the bolt body and the locking nut.

The anti-loosening cut-in type bolt structure is characterized in that the cut-in sheet is made of high-carbon steel or stainless steel, and the hardness of the cut-in sheet is not less than that of the bolt body and the locking nut.

Since the technical scheme is used, the utility model discloses following beneficial effect has:

the anti-loosening cut-in bolt structure of the utility model has the advantages that the cut-in pieces are arranged on the gasket, along with the continuous screwing of the locking nut, the internal thread circle of the locking nut is pressed on the cut-in pieces, so that the cut-in pieces slowly cut into the space between the locking nut and the bolt body, and the cut-in pieces destroy part of the internal thread of the locking nut and the external thread of the bolt body in the cut-in process; the utility model discloses simple structure, convenient to use have effectively prevented not hard up of lock nut and bolt body, and simple manufacture is fit for promoting on a large scale.

in the figure: 1. locking the nut; 2. a gasket; 3. a fastened piece; 4. a bolt body; 5. cutting into the sheet.

Detailed Description

The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.

With reference to fig. 1-2, the anti-loosening cut-in bolt structure comprises a locking nut 1, a fastened piece 3 and a bolt body 4, wherein one end of the bolt body 4 is arranged in a threaded hole of the fastened piece 3 in a penetrating manner, the bolt body 4 is fastened through the locking nut 1, a gasket 2 is arranged on the bolt body 4 between the locking nut 1 and the fastened piece 3, at least one cut-in piece 5 perpendicular to the gasket 2 is arranged on the inner annular surface of the gasket 2, and the cut-in piece 5 and the gasket 2 are arranged integrally.

In the anti-loosening cut-in type bolt structure, the upper end part of the cut-in piece 5 is in a sharp-horn shape.

In the anti-loosening cut-in type bolt structure, the thickness of the cut-in piece 5 is preferably enough to cut in between the bolt body 4 and the lock nut 1.

In the anti-loosening cut-in type bolt structure, the cut-in sheet 5 is preferably made of high-carbon steel or stainless steel, and the hardness of the cut-in sheet is not less than that of the bolt body 4 and the lock nut 1.

In the anti-loosening cut-in type bolt structure, when the locking nut 1 rotates along the bolt body 4 to fasten parts, the locking nut 1 firstly moves towards the gasket 2, in the moving process, the locking nut 1 firstly contacts with the sharp corner at the upper end part of the cut-in piece 5 of the gasket 2, the cut-in piece 5 is clamped between the locking nut 1 and the bolt body 4 by screwing the locking nut 1, along with the continuous screwing of the locking nut 1, the pressure of the locking nut 1 on the cut-in piece 5 is continuously increased, the cut-in piece 5 is pressed by one circle of internal thread of the locking nut 1, in the pressing-in process, the cut-in piece 5 enables one part of the internal thread of the locking nut 1 and the external thread of the bolt body 4 to be damaged, the cut-in piece 5 is firmly embedded between the locking nut 1 and the bolt body 4 under the pressure of the locking nut 1, so that the locking nut 1, the bolt body 4 and the cut-in, effectively preventing the locknut 1 and the bolt body 4 from loosening.

The part of the utility model not detailed is prior art.

The embodiments selected for the purpose of disclosing the invention, are presently considered to be suitable, it being understood, however, that the invention is intended to cover all variations and modifications of the embodiments, which fall within the scope of the concept and the utility model.
