Abstract
The utility model discloses a kind of safe self-locking bolt assembly, including bolt, nut, adjusting gasket and limited block；Limited block is placed in the placing groove of bolt circumferential surface upper edge its axis direction setting bar shaped, placing groove；The deep equality of limited block top width and placing groove, limited block bottom width are more than the depth of placing groove；Three faces that limited block is in contact with placing groove are plane, and curved surface is set as to outside；On bolt, adjusting gasket is located above nut for nut, adjusting gasket cooperation；Under self-locking state, nut bottom compresses the curved surface of limited block, to form self-locking mechanism in nut and limited block；In the utility model, limited block is put into placing groove by nut after adjusting to suitable position, then nut is circled round downwards half-turn, nut compresses curved surface, and nut and limited block form self-locking mechanism, and nut circles round downwards half-turn, it avoids workpiece stress excessive and deforms upon, it is safe to use.
Description
Technical field
The utility model is related to bolt field more particularly to a kind of safe self-locking bolt assemblies.
Background technology
Bolt is a kind of machine components, and bolt is by nut and screw rod fastener dimerous, bolts and nuts cooperation
It uses, is used to be fastenedly connected two or more parts (workpiece) with through-hole, is the most frequently used also most important in production industry
Union piece.
Common bolts and nuts easily loosen in long-time use so that seam is generated between the workpiece being fastenedly connected
Gap can be separated from each other workpiece when serious, cause serious production accident occurs；
In order to solve posed problems above, one bolt for being capable of self-locking of design is very necessary.
Utility model content
To solve technical problem present in background technology, the utility model proposes a kind of safe self-locking bolt assembly,
During use can self-locking, ensure that use is safer.
The utility model proposes a kind of safe self-locking bolt assembly, including bolt, nut, adjusting gasket and limited block；
Limited block is placed in the placing groove of the circumferential surface upper edge of bolt lower part its axis direction setting bar shaped, placing groove；
The deep equality of limited block top width and placing groove, limited block bottom width are more than the depth of placing groove；Limiting
Three faces that block is in contact with placing groove are plane, and curved surface is set as to outside；
On bolt, adjusting gasket is located above nut for nut, adjusting gasket cooperation；Under self-locking state, nut bottom pressure
The curved surface of tight limited block, to form self-locking mechanism in nut and limited block.
Preferably, the screw thread that setting matches with bolt, nut on the curved surface of limited block.
Preferably, the cross-sectional area of adjusting gasket is more than the cross-sectional area of nut.
In the utility model, limited block is put into placing groove by nut after adjusting to suitable position, then by nut to next time
Revolve half-turn, nut compresses curved surface, and nut and limited block form self-locking mechanism, and the nut half-turn that circles round downwards avoids workpiece stress excessive
And deform upon, it is safe to use.
Description of the drawings
Fig. 1 be the utility model proposes safe self-locking bolt assembly structure diagram.
Fig. 2 be the utility model proposes safe self-locking bolt assembly in limited block structure diagram.
Fig. 3 be the utility model proposes safe self-locking bolt assembly in structure diagram under self-locking state.
Specific embodiment
As shown in Figs. 1-3, Fig. 1 be the utility model proposes a kind of safe self-locking bolt assembly structure diagram, Fig. 2
For the utility model proposes safe self-locking bolt assembly in limited block structure diagram, Fig. 3 be the utility model proposes
Structure diagram in safe self-locking bolt assembly under self-locking state.
With reference to Fig. 1-3, the utility model proposes a kind of safe self-locking bolt assembly, including bolt 1, nut 2, spacer
Piece 5 and limited block 4；Limit is placed in the placing groove 3 of the circumferential surface upper edge of 1 lower part of bolt its axis direction setting bar shaped, placing groove 3
Position block 4；
4 top width of limited block and the deep equality of placing groove 3,4 bottom width of limited block are more than the depth of placing groove 3；
Three faces that limited block 4 is in contact with placing groove 3 are plane, and curved surface 41 is set as to outside；
Nut 2, adjusting gasket 5 coordinate on bolt 1, and adjusting gasket 5 is located at 2 top of nut；Under self-locking state, nut 2
Bottom compresses the curved surface 41 of limited block 4, to form self-locking mechanism in nut 2 and limited block 4.
In the specific work process of the safe self-locking bolt assembly of the present embodiment, by adjusting gasket 5 by nut 2 adjust to
Suitable position, after limited block 4 is put into placing groove 3, then convolution half-turn, nut 2 compress the song of limited block 4 downwards by nut 2
Face 41, nut 2 and limited block 4 form self-locking mechanism, ensure that use is safer, nut 2 downwards convolution half-turn avoid workpiece by
Power is excessive and deforms upon.
In a specific embodiment, the screw thread that setting matches with bolt 1, nut 2 on the curved surface 41 of limited block 4, nut 2
It is threadedly coupled with the curved surface 41 of limited block 4, is further ensured that the stabilization of self-locking；
Further, the cross-sectional area of adjusting gasket 5 be more than nut 2 cross-sectional area, adjusting gasket 5 can increase with
The contact area of workpiece reduces the stress of workpiece unit area, prevents workpiece from locally deforming upon.
The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
