Description
Technical field
Stop nut field is the utility model is related to, specifically a kind of stop nut with Anti-rotary block external member.
Background technology
With expanding economy, its screw thread can not meet to be actually needed using 30 ° of wedge-shaped checknuts come locking.
The content of the invention
The utility model is overcome the deficiencies in the prior art, designs a kind of stop nut with Anti-rotary block external member, passes through
The fixation of Anti-rotary block external member, improve the anti-loosening property of nut.
To achieve the above object, a kind of stop nut with Anti-rotary block external member, including bolt, nut, Anti-rotary block are designed
External member, it is characterized in that：The bolt coat is provided with nut, and the outside of nut is provided with Anti-rotary block external member, the Anti-rotary block external member half
Nut is surrounded, the groove of an arc is offered in Anti-rotary block external member, screw is embedded with groove.
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；The supporting Anti-rotary block of nut, Anti-rotary block 90
The catch with oval mounting hole is spent, Anti-rotary block ledge simultaneously contacts with any of the angle equal edge of nut 6, and nut tightens rear anti-rotation
Block position is fixed, and screw is used by arbitrarily preengaging the M4 screwed holes processed in the range of 90 degree on oval mounting hole and working face
It is fixed, play the locking effect of anti-rotation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1, wherein, 1 is bolt, and 2 be nut, and 3 be groove, and 4 be Anti-rotary block external member, and 5 be screw.
Embodiment
The utility model is described further below according to accompanying drawing.
As shown in figure 1, being arranged with nut 2 outside the bolt 1, the outside of nut 2 is provided with Anti-rotary block external member 4, the anti-rotation
The semi-surrounding nut 2 of block external member 4, the groove 3 of an arc is offered in Anti-rotary block external member 4, screw 5 is embedded with groove 3
The internal thread of the nut 2 uses 30 ° of wedge-shaped checknuts, and the internal thread tooth form structure of nut 2 is Bottom of Thread
It with the axis of thread is in 30 ° of tapered ramp to have one.
The utility model in use, nut 2 employs 30 ° of wedge-shaped checknuts, including threaded body and 30 ° of wedge shapes it is oblique
Face, by increasing locking frictional force so as to having the function that locking thread.Also, increased using Anti-rotary block external member 4 extra anti-
Loose performance, Anti-rotary block external member 4 are 90 degree of catch with oval mounting hole, and Anti-rotary block ledge is any one with nut angle equal edge's
Face contacts, and nut 1 is tightened rear Anti-rotary block position and fixed, and is added by any reservation in the range of 90 degree on oval mounting hole and working face
The good M4 screwed holes of work, which are adopted, to be screwed, and plays the locking effect of anti-rotation.
