Description
Technical field
Bolt is the utility model is related to, especially a kind of fastener of high reliability interface arrangment.
Background technology
At present, existing bonnet covers typically is respectively arranged in bonnet lower end, the grab in vehicle frame using two
Mutual clamping realizes that bonnet closes, and the grab lower end in vehicle frame is provided with torsion spring structure, when under bonnet lid
Afterwards, the grab on bonnet utilizes lower pressure, drives torsion spring to realize that grab rotates to side so that the grab on bonnet is broken away from
The obstruction of grab in vehicle frame, at the same the grab on bonnet in the obstruction for breaking away from the grab in vehicle frame in a flash, car
Grab in support body is not just pind down by lower pressure, and torsion spring rotates backward immediately so that and the grab moment in vehicle frame returns to original position,
And realize and be engaged by clamping with the grab on bonnet.It is real by torsion spring but this kind of fit system has certain use hidden danger
The grab now rotated easily occur unexpectedly it is stuck, loosen the problem of, thus may result in automobile engine cover cover it is not compact,
Have loosening, when there is stuck situation, control device, which can not be realized, opens bonnet, it is necessary to manually pierce underbody, using manually or
Person realizes that bonnet is opened by instrument；Loosening problem is due to that vehicle is caused vehicle to be shaken by extraneous factor in the process of moving
Influence, at the same in general driver be will not this technical ability, and Some vehicles are in the process of moving due to the shake of bonnet
Sound is small, and driver is typically not easy to discover, but bonnet covers and can tightly not cause vehicle potential safety hazard to be present, it is impossible to
Ensure the safety problem of driver.
Utility model content
The utility model will solve the shortcomings that above-mentioned prior art, there is provided a kind of rational in infrastructure, easy to use is highly reliable

Toughness, especially buckle, conventional external force can not cause buckle to produce bending, can only be realized by artificial external force, effectively anti-
The situation that only bonnet is shaken or automatically opened up occurs, and guarantee covers close, the also safe driving of guarantee driver.Maintenance workers
In work, interpolating unit is changed.
Further perfect, the outer contour shape of force section is prismatic.So, prismatic structure is easy to force section and rotation
Clamping tool coordinates, and passes through instrument screwing bolts body.
Further perfect, the outer contour shape of interpolating unit is spherical.So, the wide spy in narrow centre above and below spherical structure is utilized
Point so that interpolating unit carries interpolating unit, and without adding add-on parts, and snap effect is good.
Further perfect, interpolating unit upper and lower ends have the incoordinate section of cross-sectional area.So, the setting in section is first
It was connected before this for the ease of interpolating unit with connecting portion, next to that for the ease of realizing that bonnet steadily covers, compactness is good, stability
It is good, in the absence of shake hidden danger.
Further perfect, the outer contour shape of connecting portion is cone.So, conical structure setting causes connecting portion
In up-small and down-big shape, while being easy to be connected with force section, interpolating unit, also allow for head and can be completely disposed to be used cooperatively with it
Counterpart in, ensure to be fitted close, and counterpart can be reduced affected by jitter with concora crush in vehicle frame.
Further perfect, force section, connecting portion are to be integrally formed part using phase same material.So, it is integrally formed to set
The processing technology for simplifying bolt body is put, reduces cost of manufacture.
It is further perfect, the rib of lopping is provided around between force section and connecting portion.So, so it is provided for
Strengthen interpolating unit so that interpolating unit is overall fuller, and the cooperation with counterpart is also even closer.
Further perfect, force section bottom surface is fixed with banking pin of the ring around distribution.So, banking pin is embedded in and applied
In the part of power portion bottom surface contact, effectively prevent screw rod from producing reversion abjection.
The utility model has the advantages that：The utility model is rational in infrastructure, and using effect is good, passes through the three of bolt head
Individual part, it can realize outside the basic function that bolt body can be tightened in vehicle frame, can also be by the use of being used as interpolating unit
Interpolating unit realizes the cooperation that covers between bonnet and vehicle frame, and interpolating unit spherical form designs and to cover tight ness rating height, does not deposit
In fit clearance, while formed and be engaged by clamping using neck and buckle between interpolating unit and connecting rod, can ensure that vehicle is run over
In journey under the influence of by continuous disturbances, interpolating unit is nonreversible, coordinates stabilization, ensures the safe driving of driver.
