Description
Technical field
The invention belongs to fastener areas, and in particular to a kind of five jiaos of nylon anti-loose anti-theft nuts.
Background technology
As climate warming, carbon emission issues associated are of increasing concern, and expanding economy, a kind of new shared warp
Ji --- shared bicycle comes into being.A large amount of with shared bicycle launch, and bring certain difficulty to its management, frequently result in
Chain transmission system is stolen the generation of phenomenon.Existing shared bicycle is using the hexagonal locking nut after 4~5mm to chain both sides
Pedal crank carries out locking installation, it is only necessary to can be dismantled using existing extracting tool, it is extremely easily stolen.It is existing at the same time
The locking effect of some hexagonal locking nuts is undesirable, and its easily loosens during the motion, and then causes whole group
The loosening of part, retard motion and stuck and so on, may further cause casualties and the heavy losses of property.
Therefore, in order to solve problem above develop one kind can either Anti-dismantling, improve anti-theft effect, while can ensure
The nut of sports safety is those skilled in the art institute urgent need to solve the problem.
The content of the invention
To solve the above problems, the invention discloses a kind of five jiaos of nylon anti-loose anti-theft nuts.
In order to achieve the above object, the present invention provides following technical solution：
A kind of five jiaos of nylon anti-loose anti-theft nuts, including pentagon nut body and nylon washer, pentagon nut body include
Cap in nut lower body and nut；Nut lower body is provided with threaded circular post holes, and the outer contour of nut lower body vertically
For pentagon；Cap is ring-type on nut, is shaped in the top of nut lower body, and cap and nut lower body on nut
Inner side junction is provided inwardly with annular groove；The axial cross section of annular groove has the opening towards annular groove center；Nylon washer is matched somebody with somebody
Closing and be arranged in annular groove, the internal diameter of nylon washer is less than the diameter of threaded circular post holes, and more than the internal diameter of cap on nut.
The present invention provides a kind of five jiaos of nylon anti-loose anti-theft nuts, it is made of pentagon nut body and nylon washer.
Wherein pentagon nut body is made of one piece by cap on nut lower body and nut, and nut lower body is provided with screw thread along axis
Cylindrical hole, it is spacing for tightening, and the outer contour of nut lower body is designed as pentagon, and which uses and existing hexagonal spiral shell
Female entirely different outer contour, effectively avoids directly dismantling the present invention using instruments such as existing spanners, effectively lifting
Anti-theft effect.Nut upper mold is designed as ring-type in the present invention, and the inner side junction of itself and nut lower body is provided inwardly with annular groove,
The axial cross section of annular groove has the opening towards annular groove center, and nylon washer, the internal diameter of nylon washer are installed for coordinating
It is designed as being less than thread cylinder bore dia, and more than the internal diameter of cap on nut, ensures that nylon washer can be stablized and be arranged at annular
In groove, the anti-loosening locking function of nylon washer is further ensured.
Preferably, threaded circular post holes is set for the eccentric with nut lower body.
The selection of threaded circular post holes and nut lower body in the present invention are in eccentric setting, which causes the present invention not lead to
Cross and dismantled using the existing instrument comprising interior five jiaos, substantially increase the anti-theft feature of the present invention, at the same also without prejudice to
Carry out tightening installation using specific instrument.
Preferably, the thickness of pentagon nut body is not less than 9mm.
The thickness selected as of pentagon nut body is not less than 9mm in the present invention, which ensures the present invention when mounted
Coordinate contact surfac is longer, and installation effect is more excellent.
Preferably, the thickness of nylon washer is 2~3 times of pitch in threaded circular post holes.
The thickness of nylon washer is designed as 2~3 times of pitch in threaded circular post holes in the present invention, which both can guarantee that Buddhist nun
The locking effect of imperial packing ring, while can also prevent from causing nut lower body not lock since nylon washer is blocked up, or locking
It is difficult.
Preferably, cap has the smooth top surface of arcuation on nut.
Cap is also designed with the smooth top surface of arcuation on nut in the present invention, can be prevented using cap on nut to the present invention
Dismantled.
Preferably, nut lower body and the surface of cap on nut are respectively provided with zinc coat.
Nut lower body and the surface of cap on nut are equipped with zinc coat in the present invention, entirety of the invention are played good
Protection and decorative effect.
Compared with prior art, the present invention using pentagonal outer contour so that need special instrument to be dismantled, have
Effect improves anti-theft feature；Using the width design more than 9mm, to be carried out to the thickness of nylon washer and threaded circular post holes
Adjust so that locking effect is more outstanding, avoids the accident such as generating assembly loosening, retard motion, stuck during the motion
Caused casualties and property loss.
