Abstract
Component of machine manufacturing technology field is the utility model is related to, is concretely a kind of anti-loose anti-theft nut with crushing block external member, including：Nut body, crushing block external member, the inner ring of nut body offers a square groove, square groove is furnished with crushing block external member, the nut body internal thread tooth bottom is equipped with tapered ramp, angle between tapered ramp and internal thread lower plane reverse extending line is 30 °, after bolt and the utility model are mutually tightened, the cusp of bolt is just withstood on 30 ° of tapered ramps of the utility model, make normal force caused by the contact that is applied between screw thread and bolt axis into 30 ° of 60 ° of angles rather than regular screw threads, increase locking frictional force so as to reach anti-loosing effect, crushing block external member is knocked in using specific purpose tool after nut is tightened, play antitheft locking effect.
Description
Technical field
Component of machine manufacturing technology field is the utility model is related to, is concretely a kind of with crushing block external member
Anti-loose anti-theft nut.
Background technology
With expanding economy, screw thread cannot meet to be actually needed using 30 ° of wedge-shaped checknuts come locking, especially
It is that common existing checknut can not meet customer requirement in some parts assemblings high for fastening requirements,
As soon as and the loss of nut is also a problem in mechanical equipment running, therefore needs to design a kind of fastening ability height, be not easy
Lose and the low stop nut of production cost.
The content of the invention
The utility model breaches the problem of the prior art, and it is high, not easy to lose and be produced into devise a kind of fastening ability
This low stop nut.
In order to achieve the above object, the utility model devises a kind of anti-loose anti-theft nut with crushing block external member, including：
Nut body, crushing block external member, it is characterised in that：The inner ring of nut body offers a square groove, and square groove is equipped with extruding
Block external member, the nut body internal thread tooth bottom are equipped with tapered ramp, tapered ramp and internal thread lower plane reverse extending line
Between angle be 30 °.
The crushing block external member is " L " type.
Compared with prior art, after bolt and the utility model are mutually tightened, the cusp of bolt just pushes up the utility model
On 30 ° of tapered ramps of the utility model, normal force caused by the contact that makes to be applied between screw thread is with bolt axis into 60 °
Angle rather than 30 ° of regular screw threads, increase locking frictional force so as to reach anti-loosing effect, by crushing block external member after nut is tightened
Knocked in using specific purpose tool, play antitheft locking effect.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is nut body internal thread structure and force diagram schematic diagram in the utility model.
Fig. 1 ~ Fig. 2,1 is nut body, and 2 be square groove, and 3 be tapered ramp, and 4 be crushing block external member.
Embodiment
The utility model is described further with reference to attached drawing.
Referring to Fig. 1 ~ Fig. 2, the utility model devises a kind of anti-loose anti-theft nut with crushing block external member, including：Nut
Body, crushing block external member, it is characterised in that：The inner ring of nut body 1 offers a square groove 2, and square groove 2 is furnished with crushing block
External member 4, the 1 internal thread tooth bottom of nut body are equipped with tapered ramp 3, tapered ramp 3 and internal thread lower plane reverse extending
Angle between line is 30 °.
Crushing block external member 4 is " L " type in the utility model.
In specific implementation, after bolt and the utility model are mutually tightened, the cusp of bolt just withstands on the utility model
30 ° of tapered ramps on, make normal force caused by the contact that is applied between screw thread and bolt axis into 60 ° of angles rather than common
30 ° of screw thread, increase locking frictional force so as to reach anti-loosing effect, strike extruding external member using specific purpose tool after nut is tightened
Enter, play antitheft locking effect, when nut to be dismantled if need to knock out crushing block external member by specific purpose tool, just can pine
Dynamic nut.
