Description
Technical field
The utility model belongs to a kind of device of the fastening car plate on vehicle, particularly a kind of car plate tamper fastening
Device.
Background technology
Although car plate on existing vehicle, its fixing device also allows for Anti-dismantling problem, but it is that normal screws are twisted
Fixed inner screw nut is tightened, it is impossible to fundamentally solve the problems, such as that car plate can be disassembled.Existing car plate holds in use
It is easy to fall off, such as：Car plate loosens by concussion nature for a long time, easily causes car plate loss；Vehicle is in the impulse force that makes because of water of paddling
Car plate can be caused to lose, etc..Especially for board personnel or lawless person violating the regulations is related to, with simplest portable dam at any time
Car plate can be dismantled, vehicle illegal and many social concerns using car plate crime be caused, to traffic safety, the people
The life security and property safety of the masses cause great hidden danger.Therefore, to be fastened on how car plate non-dismountable on vehicle
It is a big problem for being related to people's safety, can not be ignored.
The content of the invention
In view of the consideration to problem above, the purpose of this utility model is that a kind of car plate fastening for making vehicle of invention is non-disconnectable
The device for unloading.
The utility model is to reach its purpose using following technical proposals：
A kind of car plate Anti-dismantling fastener, including upper protective cover, one-way bolt, hexagonal locknut and interior hexagonal retaining
Screw；On the bolt head of one-way bolt, the shank of bolt of one-way bolt is from the top of hexagonal locknut for described protective cover spiral-lock
End is screwed into hexagonal locknut, and the bottom of one-way bolt is in inside hexagonal locknut；Add in the bottom of one-way bolt
Work has a taper angle；Described interior hexagonal stopping screw is also screwed into hexagonal locknut from the bottom of hexagonal locknut
Portion, the head of interior hexagonal stopping screw is taper, is held out against in the taper angle of one-way bolt bottom；The cone of one-way bolt bottom
Corresponding groove is equipped with shape angle and on the conical nose of interior hexagonal stopping screw, collar is provided with groove, make list
It is connected together to bolt and interior hexagonal stopping screw.
There is the horizontal groove of a circle in the bolt head outer surface of one-way bolt, also have a circle therewith in upper protection interior surface
Relative horizontal groove, places an earless back-up ring in two described grooves.
A pad is placed in the bolt head bottom of one-way bolt, one is carried towards the top of protective cover in hexagonal locknut
The outer flange relative with pad.
The beneficial effects of the utility model are：
Overall structure is simple, easy for installation, can anti-dropout, Anti-dismantling, it is anti-twist off, pick-proof.The utility model is fundamentally
Protection safety and antitheft effect are served, is a kind of product with extensive social effect.
Brief description of the drawings
Fig. 1 is the utility model car plate tamper fastener overall structure diagram,
Fig. 2 is the A portions enlarged diagram in Fig. 1.
Marked in figure：1. go up protective cover, 2. one-way bolt, 3. hexagonal locknut, 4. in hexagonal stopping screw, 5. earless
Back-up ring, 6. pad, 7. collar.
Specific embodiment
Referring to Fig. 1-Fig. 2, the utility model stops including upper protective cover 1, one-way bolt 2, hexagonal locknut 3 and interior hexagonal
Move back screw 4.On the bolt head of one-way bolt 2, the shank of bolt of one-way bolt 2 is from locking hexagonal spiral shell for the described spiral-lock of protective cover 1
Female 3 top is screwed into hexagonal locknut 3, and the bottom of one-way bolt 2 is in inside hexagonal locknut 3.In unidirectional spiral shell
The bottom of bolt 2 is machined with a taper angle.Described interior hexagonal stopping screw 4 is also screwed into from the bottom of hexagonal locknut 3
Inside hexagonal locknut 3, the head of interior hexagonal stopping screw 4 is taper, holds out against the taper angle in the bottom of one-way bolt 2
In.The groove for matching is equipped with the taper angle of the bottom of one-way bolt 2 and on the conical nose of interior hexagonal stopping screw 4,
Collar 7 is provided with groove, one-way bolt 2 and interior hexagonal stopping screw 4 is connected together.In the bolt head of one-way bolt 2
A pad 6 is placed in bottom, and an evagination relative with described pad 6 is carried towards the top of protective cover 1 in hexagonal locknut 3
Side.There is the horizontal groove of a circle in the bolt head outer surface of one-way bolt 2, also have circle phase therewith in the inner surface of upper protective cover 1
To horizontal groove, an earless back-up ring 5 is placed in described two grooves, play the clip of upper protective cover 1 mounted in unidirectional
Effect on the bolt head of bolt 2.Described collar 7 and earless back-up ring 5 are metallic article (generally steel product).
During assembling, stop nut 3 is first fixed on the inside of vehicle installation position, one-way bolt 2 is penetrated into from outside
Tightened in hexagonal locknut 3.Pad 6 plays a part of sealing, fastening and protection and does not injure vehicle installation place.At this moment again with peace
The interior hexagonal stopping screw 4 for loading onto collar 7 is screwed into the bottom of stop nut 3, until being screwed to collar 7 while being stuck in the He of stop nut 3
In the groove of one-way bolt 2.Finally upper protective cover 1 is pressed, the bolt head of one-way bolt 2 is engaged by back-up ring 5, assembled
Finish.
Anti-dismantling effect of the present utility model is that the double insurance played by two structures is realized：
1st, the structural relation between collar and one-way bolt, interior hexagonal stopping screw and hexagonal locknut, makes unidirectional spiral shell
It is movable connection between bolt and the interior hexagonal stopping screw of bottom, when head protector is destroyed, from hexagonal locknut outwards
When turning one-way bolt, collar plays a part of interior hexagonal stopping screw can not be rotated with one-way bolt, block one-way bolt
Back-out.Serve the effect of Anti-dismantling.
2nd, further, the structural relation between earless back-up ring and head protector and one-way bolt, makes head protector be difficult from unidirectional
Pulled down on bolt；Also, earless back-up ring can only make head protector form the form of any rotation in left and right, and one-way bolt can not be driven to turn
It is dynamic, serve the effect protected in advance.
