Abstract
Stop nut field is the utility model is related to, specifically a kind of angle of articulation is more than the stop nut of the flange surface toothed of lead angle.Including nut, bolt, it is characterized in that：Bolt is embedded with the inside of the nut, a circle tooth form is offered on the flange face of nut, the tooth form angle in the nut flange face is more than the angle of the externally threaded lead angle of bolt.The utility model is compared with the existing technology, simple in construction, easy to use；When nut and working face are engaged, toothed surface is more than corresponding externally threaded lead angle with the angle of articulation of working face equal to tooth form angle, in external force vibration because both angle decentractions, so as to effectively prevent the trend of thread looseness, so as to reach the purpose for improving nut anti-looseness effect.
Description
Technical field
Stop nut field is the utility model is related to, specifically a kind of angle of articulation is more than the flange face of lead angle
Toothed stop nut.
Background technology
With expanding economy, stop nut can not meet actual need using 30 ° of wedge checknuts come locking
Will.
The content of the invention
The utility model is overcome the deficiencies in the prior art, designs a kind of stop nut of the nut flange face with tooth form, and
The angle of articulation of nut flange face tooth form is more than lead angle, reaches the purpose for improving nut anti-looseness performance.
To achieve the above object, a kind of stop nut of angle of articulation more than the flange surface toothed of lead angle, bag are designed
Include nut, bolt, it is characterized in that：Bolt is embedded with the inside of the nut, a circle tooth form, institute are offered on the flange face of nut
The tooth form angle for stating nut flange face is more than the angle of the externally threaded lead angle of bolt.
The internal thread of the nut uses 30 ° of wedge-shaped checknuts, and the internal thread tooth form structure of nut has for Bottom of Thread
One with the axis of thread is in 30 ° of tapered ramp.
The utility model is compared with the existing technology, simple in construction, easy to use；When nut and working face are engaged, tooth form
Face is more than corresponding externally threaded lead angle with the angle of articulation of working face equal to tooth form angle, in external force vibration because of both
Angle decentraction, so as to effectively prevent the trend of thread looseness, so as to reach the purpose for improving nut anti-looseness effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation in nut flange face in the utility model.
Referring to Fig. 1~Fig. 2, wherein, 1 is nut, and 2 be bolt, and 3 be tooth form.
Embodiment
The utility model is described further below according to accompanying drawing.
As shown in Fig. 1~Fig. 2, the inner side of the nut 1 is embedded with bolt 2, and a circle tooth is offered on the flange face of nut 1
Shape 3, the angle of tooth form 3 of the flange face of nut 1 are more than the angle of 2 externally threaded lead angle of bolt.
The internal thread of the nut 1 uses 30 ° of wedge-shaped checknuts, and the internal thread tooth form structure of nut 1 is Bottom of Thread
It with the axis of thread is in 30 ° of tapered ramp to have one.
The utility model in use, the internal thread tooth bottom of nut 1 is provided with a tapered ramp, described tapered ramp with
Angle between described internal thread lower plane reverse extending line is 30 °.After bolt 2 and nut 1 are mutually tightened, bolt 2
Cusp is just withstood on 30 ° of lozenges of nut 1.Due to the change of tooth form angle, make caused by the contact that is applied between screw thread
Into 30 degree of 60 degree angles rather than regular screw threads, caused locking frictional force increases so as to reach anti-for normal force and bolt axis
Loose effect.When nut 1 and working face are engaged simultaneously, the face of tooth form 3 and the angle of articulation of working face are equal to tooth form angle and are more than pair
Externally threaded lead angle is answered, in external force vibration because both angle decentractions, so as to effectively prevent thread looseness
Trend, so as to reach the purpose for improving nut anti-looseness effect.
Claims (2)
1. a kind of angle of articulation is more than the stop nut of the flange surface toothed of lead angle, including nut, bolt, it is characterized in that：
The nut（1）Inner side be embedded with bolt（2）, nut（1）Flange face on offer a circle tooth form（3）, the nut（1）
The tooth form of flange face（3）Angle is more than bolt（2）The angle of externally threaded lead angle.
2. a kind of angle of articulation as claimed in claim 1 is more than the stop nut of the flange surface toothed of lead angle, its feature
It is：The nut（1）Internal thread use 30 ° of wedge-shaped checknuts, nut（1）Internal thread tooth form structure have for Bottom of Thread
One with the axis of thread is in 30 ° of tapered ramp.
