Description
Technical field
Anti-loose anti-theft nut field is the utility model is related to, specifically a kind of nut side is anti-with wedged block external member
Loose anti-theft 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 nut for having locking functions and anti-theft feature concurrently,
The external member with wedged block is opened up in the side of nut, the purpose for reaching locking by increasing locking frictional force, by increasing wedge
Block reaches antitheft purpose.
To achieve the above object, a kind of anti-loose anti-theft nut of nut side with contract type block external member, including nut, spiral shell are designed
Bolt, it is characterized in that：The bolt coat is provided with nut, and the side of the nut offers groove, and the left and right ends of the groove are run through
The side of nut, wedged block is embedded with groove.
The inner side of the wedge abuts the external screw thread of bolt.
The internal thread of the nut uses 30 ° of wedge 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 wedge inclined-plane.
The utility model is compared with the existing technology, simple in construction, easy to use；It is anti-using 30 ° of wedge checknuts, increase
Loose frictional force, reach locking purpose；In groove using wedged block inserted num, the top of wedged block is held out against to bolt, is played
Antitheft purpose.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1, wherein, 1 is nut, and 2 be contract block, and 3 be groove, and 4 be bolt.
Embodiment
The utility model is described further below according to accompanying drawing.
As shown in figure 1, being arranged with nut 1 outside the bolt 4, the side of the nut 1 offers groove 3, a left side for the groove 3
The side of nut 1 is run through at right both ends, and wedged block 2 is embedded with groove 3.
The inner side of the wedged block 2 abuts the external screw thread of bolt 4.
The internal thread of the nut 1 uses 30 ° of wedge 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 wedge inclined-plane to have one.
The utility model is in use, the internal thread of nut 1 employs 30 ° of wedge checknuts, including threaded body and 30 °
Wedge inclined-plane, by increasing locking frictional force so as to having the function that locking thread；The groove at side surface 3 of nut 1, it is supporting corresponding
Wedged block 2, nut knock in wedged block 2 after tightening, and the inside bolt is held out against by wedged block 2, plays locking effect.Separately
It is outer dismounting nut when need take specific purpose tool by wedged block 2 knock out can loose nut 1, so as to play antitheft effect.
