Description
Technical field
The utility model relates to a kind of fasteners, more specifically, it relates to a kind of high reliability anti-theft bolt.
Background technique
Many products for outdoor, it is many insufficient due to having in management, and just greatly reduced using anti-theft bolt
Unnecessary loss.
In the prior art, the opening on nut is usually arranged to different shape by many producers, so that ordinary person is not
Bolt is turned with by general tool, so that bolt be made to have anti-theft effect.
But it is usually to produce in batches, and then be easy to cause ordinary person also and can have and obtain phase that producer, which produces these parts,
The ability for the tool matched, it is undesirable so as to cause the anti-theft effect of bolt, have much room for improvement.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of high reliability anti-theft bolt,
It can be tightened, but bolt can not unscrewed using general tool.
To achieve the above object, the utility model provides following technical solution:
A kind of anti-theft bolt of high reliability, including screw rod and nut, are arranged with gasket on the screw rod, the nut and
Locking assembly is provided between gasket, the gasket is provided with several self threading pins, the locking assembly energy away from one end of nut
Enough relative rotations limited after tightening bolt between nut and gasket.
By using above-mentioned technical proposal, bolt during tightening, can relatively rotate, and then right with gasket
Self threading pin is squeezed and gasket is fixed, and after further tightening bolt, locking assembly can limit nut and pad
Relative rotation between piece, so that nut is relatively fixed with gasket and realizes anti-theft effect, this bolt is only needed using general
Logical tool can be operated, but general tool but it can not be dismantled, have excellent anti-theft effect, have highly reliable
Property.
The utility model is further arranged to: the locking assembly include be set to nut towards screw rod side it is several on
Helical teeth, several upper helical teeth are evenly distributed along the circumferencial direction of nut, and each adjacent upper helical teeth mutually abuts, the pad
The side of piece towards fixed ring is provided with several helical teeth under cooperating with upper helical teeth, bolt several upper helical teeth after tightening
It is mutually twisted with lower helical teeth.
By using above-mentioned technical proposal, by the mutual cooperation of several upper helical teeth and lower helical teeth, in the mistake of tightening nuts
Cheng Zhong, upper helical teeth and lower helical teeth have the function of mutually being oriented to, and after being screwed to a certain degree, guiding role is not enough to overcome crowded
When pressure, then represents and tighten anti-theft bolt, and anti-rotation bolt at this time, several upper helical teeth and lower helical teeth are in be mutually twisted shape
State.
The utility model is further arranged to: the end face of the nut towards screw rod is provided with fixed ring, it is several it is described on
Helical teeth is set to the side that fixed ring deviates from nut.
The quantity of helical teeth is capable of increasing and along fixation by the setting of fixed ring by using above-mentioned technical proposal
The length of ring radial direction, so that upper helical teeth and lower helical teeth have preferably occlusion effect.
The utility model is further arranged to: rubber pad, the upper rubber are provided between the fixed ring and nut
The two opposite sides of pad are mutually fixed with fixed ring and nut respectively.
By using above-mentioned technical proposal, due to having the function of mutually being oriented between upper helical teeth and lower helical teeth, Jin Er
During tightening bolt, nut can generate certain shift reciprocately, and it is effective that upper rubber pad then passes through its elastically-deformable ability
Avoid the problem.Meanwhile the deformation of upper rubber pad ensure that and can closely be engaged between helical teeth and lower helical teeth.
The utility model is further arranged to: lower rubber pad is arranged away from the side of nut in the gasket, it is several it is described from
Nail is attacked through lower rubber pad.
By using above-mentioned technical proposal, the buffering to gasket and fixed ring is further improved by lower rubber pad, together
When further ensure and can be closely engaged between helical teeth and lower helical teeth.Rubber has bigger friction compared with alloy
Power can be improved stability of gasket during turning, and avoid causing self threading pin to bend during rotating bolt.
The utility model is further arranged to: the lower rubber pad when being not affected by extruding the end of several self threading pins under
The end face flush of rubber pad.
By using above-mentioned technical proposal, while can be avoided staff and accidentally injured by self threading pin, gasket is easily facilitated
Positioning in bolt rundown process.
The utility model is further arranged to: the lower rubber pad is provided with several anti-skidding convex away from the side of fixed ring
It rises.
The antiskid effect of lower rubber pad is improved by the setting of several anti-skid bulges by using above-mentioned technical proposal,
Further improve the stability of gasket.
The utility model is further arranged to: the quantity of the self threading pin is set as three, and three self threading pins are along pad
The circumferencial direction of piece is evenly distributed.
By using above-mentioned technical proposal, while three self threading pins can make gasket obtain good stability, can drop
Low difficulty of processing.
In conclusion the utility model has the following beneficial effects:
It 1. bolt is during tightening, can relatively rotate with gasket, and then self threading pin is squeezed and is made
Gasket is obtained to be fixed, after further tightening bolt, locking assembly can limit the relative rotation between nut and gasket, into
And make nut relatively fixed with gasket and realize anti-theft effect, this bolt only needs to can be operated using general tool, but general
Lead to tool but it can not be dismantled, there is excellent anti-theft effect；
2. by the mutual cooperation of several upper helical teeth and lower helical teeth, during tightening nuts, upper helical teeth and lower helical teeth
Have the function of mutually being oriented to, after being screwed to a certain degree, when guiding role is not enough to overcome extruding force, then represents and incited somebody to action
Anti-theft bolt is tightened, and anti-rotation bolt at this time, several upper helical teeth and lower helical teeth are in be mutually twisted state；
3. acting on by upper rubber pad and lower rubber pad the elastic buffer of fixed ring and gasket, it ensure that helical teeth under
Helical teeth is mutually twisted effect.
