Abstract
It the utility model is related to machanical fastener manufacturing technology field, concretely it is a kind of stop nut of side with continuous triangle shape groove, including nut body and vee gutter, change pitch thread tooth bottom inside nut body is equipped with tapered ramp, nut body three offers vee gutter on adjacent continuous side, 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, when nut bolt is tightened at the same time, influenced by screw thread pulling force, the part deformation that left one side of something holds continuous triangle shape groove can produce an out of plumb bolt axis direction pressure to the axis direction of bolt, so as to which that improves nut loosens performance.
Description
Technical field
Machanical fastener manufacturing technology field is the utility model is related to, is concretely a kind of side band continuous triangle
The stop nut of shape groove.
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,
Therefore just need to design the stop nut that a kind of fastening ability is high and production cost is low.
The content of the invention
The problem that the utility model breaches the prior art devises that a kind of fastening ability is high and that production cost is low is locking
Nut.
In order to achieve the above object, the utility model devises a kind of stop nut of side with continuous triangle shape groove, bag
Include nut body and vee gutter, it is characterised in that：Change pitch thread tooth bottom inside nut body is equipped with tapered ramp, nut
Body three offers vee gutter on adjacent continuous side.
The angle become between pitch thread lower plane reverse extending line inside the tapered ramp and nut body is 30 °.
The quantity of the vee gutter is 3.
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, while when nut bolt is tightened, are influenced by screw thread pulling force, left one side of something
An out of plumb bolt axis direction pressure can be produced to the axis direction of bolt by holding the part deformation of continuous triangle shape groove, from
And that improves nut loosens performance.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is to become pitch thread structure and force diagram schematic diagram in the utility model.
Referring to Fig. 1, Fig. 2,1 is nut body, and 2 be vee gutter, and 3 be tapered ramp.
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 stop nut of side with continuous triangle shape groove, including nut
Body and vee gutter, the change pitch thread tooth bottom inside nut body 1 be equipped with tapered ramp 3, and nut body 1 three is adjacent
Vee gutter 2 is offered on continuous side.
Becoming between pitch thread lower plane reverse extending line inside tapered ramp 3 and nut body 1 in the utility model
Angle is 30 °.
The quantity of the utility model intermediate cam shape groove 2 is 3.
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, while when nut bolt is tightened, are influenced by screw thread pulling force, left one side of something opens continuous triangle shape
The part deformation of groove can produce an out of plumb bolt axis direction pressure to the axis direction of bolt, so as to improve nut
Loosen performance, and the utility model can freely coordinate with the external screw thread of standard, and the externally threaded tolerance coordinated is in 6g
More than.
Claims (3)
