Description
Technical field
The present invention relates to a kind of bolt, more particularly to a kind of expansion bolt.
Background technology
Expansion bolt includes swell fixture and the nut and expansion sleeve that match therewith, wherein swell fixture bolt end
For round platform nail-head or circular platform type nut is set to, in use, swell fixture or nut are tightened, round platform nail-head or circular platform type
Nut enters in expansion sleeve from small end to big side pressure, forces expansion sleeve dilatancy, and expand in mounting hole.
And existing expansion sleeve only has single sleeve pipe, its dilatancy is small, causes connecing for expansion sleeve and inflation port
Contacting surface product is small, and whole expansion bolt is very easy to come off out of inflation port.
The content of the invention
For above-mentioned produced problem, the invention provides a kind of structure effectively, expansion effect is good, bonding strength after expansion
Height, the good expansion bolt of supporting effect.
Expansion bolt, including tightening latch, bolt set and nut；The tightening latch top is taper head, and tightening latch body of rod lower end is set
There is screw thread；The bolt set includes the first bolt set, the second bolt set and the 3rd bolt set, and the first bolt set is set close to taper head, and second
Bolt is covered and the 3rd bolt set is sequentially sleeved on tightening latch；First bolt set symmetrically arranged is opened close to tapered rod rostral provided with multiple
Set at mouth groove, opening channel opening for arc, cell body covers spiral setting along the first bolt；The nut is set in after the 3rd bolt set
Side.
The enhancing muscle consistent with opening channel opening lines is provided with the first bolt set side wall.
The second bolt set is plastics bolt set.
The second bolt set upper semisection is designed as outer male structure；Bottom is provided with one layer of thickening extrusion ring.
The 3rd bolt set is to be provided with enhancing lines on metal bolt set, bolt set side wall.
The enhancing muscle length that first bolt is put is more than opening slot length.
Second bolt be enclosed on the first bolt set with the 3rd bolt set crimp obtain end-state when, the second bolt set evagination
Width is more than 3/2 width of taper head.
Elastomeric pad and pad are provided between the nut and the 3rd bolt set.
Compared with prior art, have the advantage that for：The bolt gone out in taper head covers its open slot and set for arc,
After bolt set is squeezed due to lines is squeezed when strength it is inconsistent, irregular deformation, the tilting end shape of bolt set occur for bolt set
The radian of curl, helical form radian adhesive force degree in wall has the power more strengthened relative to conventional deformation radian
Degree, the deformation of plastics bolt set can form second embolism structure, strengthen the reliability of bolt.
Brief description of the drawings
Fig. 1 is the structural representation of expansion bolt of the present invention.
Fig. 2 is the sectional view that the second bolt of the invention covers.
Embodiment
It is illustrated as a kind of embodiment of expansion bolt of the present invention, including tightening latch 1, bolt set and nut；The tightening latch top is
Taper head, tightening latch body of rod lower end is provided with screw thread；The bolt set includes the first bolt and covers the 2, second bolt set 3 and the 3rd bolt set 4, the
One bolt set is set close to taper head, and the second bolt set and the 3rd bolt set are sequentially sleeved on tightening latch；The first bolt set is close to cone
Shape head side is provided with multiple symmetrically arranged open slots 5, and opening channel opening 6 is set for arc, and cell body covers spiral along the first bolt
Set；The nut 7 is set in the 3rd bolt set rear side.
Further, it is provided with the enhancing muscle 8 consistent with opening channel opening lines on the first bolt set side wall.
Further, the second bolt set is plastics bolt set.
Further, the second bolt set upper semisection is designed as outer male structure 9；Bottom is provided with one layer of thickening extrusion ring
10。
Further, the 3rd bolt set is to be provided with enhancing lines 11 on metal bolt set, bolt set side wall.
Further, the enhancing muscle length that first bolt is put is more than opening slot length.
Further, second bolt be enclosed on the first bolt set with the 3rd bolt set overstock deformation obtain end-state when, second
The evagination width of bolt set is more than 3/2 width of taper head.
Further, elastomeric pad and pad are provided between the nut and the 3rd bolt set.
The first bolt set arc opening groove of the present invention is set, in the extruding of taper head, the jacket wall covered due to bolt by
When power is conducted, lateral external force is formed, causes bolt set to tilt when end is deformed upon and also produces lateral turnover, causes to dig part and exists
Hook arrangement is formed in wall, has stronger firmness relative to conventional conventional expanded structure, the first bolt covers adding for side wall
Strengthening tendons prevents from digging end because deformation is acutely broken at upset structure；Second plastics bolt set compressional deformation is formed in passage
Embolism structure, strengthens the bonding strength of bolt, while plastics bolt set is small for the destruction in passage, reduction digs portion due to multiple
Destruction of the part to passage inner wall so that whole passage expands damage area so that passage is sent to area expansion, reduces bolt
It is firm.
