The general employing of existing utilization vehicular sideview suspender arranges fixed base, and suspender cantilever and fixed base are with bolts, and bolt connects the advantages such as to have cost low, and operation is simple, and maintainability is strong of comparing other Placements.
Ensure that suspender does not come off, bolted undoubtedly reliability is most important, present stage bolt connection is general adopts friction locking, mechanical locking and forever locking, rub locking, machinery locking be called detachably locking, permanent locking be called non-dismountable locking, non-dismountable locking meeting causes while changing bolt and needs professional tool, and maintenance cost is increased, and therefore general employing of present stage is detachable locking.Detachable locking under the impact of shock loads or alternate load etc., use for a long time, frequently can there is the phenomenon of locking inefficacy, if do not found in time, be very easy to cause suspender to come off, bring potential safety hazard, affect traffic safety.
Summary of the invention
The purpose of this utility model is: a kind of fixed structure of vehicular sideview suspender is provided, does not change under bolted early stage, increase extremely low cost, the problem that comes off of suspender while solving bolt Joint failure.
Technical solution of the present utility model is:
A kind of fixed structure of vehicular sideview suspender, comprise fixed base, bolt and nut, described fixed base is fixed on mounting plane, suspender cantilever is fastened on the top of fixed base by bolt and nut, its special way is: described fixed structure also comprises the block that is positioned at suspender cantilever top, described block is fixed on mounting plane, on described block, be provided with bolt hole, the size of described bolt hole can make bolt head pass through, the screw rod of bolt passes through block from top to bottom successively, suspender cantilever and fixed base, nut coordinates with bolt fastening to suspender cantilever and fixed base.
A kind of fixed structure of vehicular sideview suspender, comprise fixed base, bolt and nut, described fixed base is fixed on mounting plane, suspender cantilever is fastened on the below of fixed base by bolt and nut, its special way is: described fixed structure also comprises the block that is positioned at suspender cantilever below, described block is fixed on mounting plane, on described block, be provided with bolt hole, the size of described bolt hole can make nut pass through, the screw rod of bolt passes through fixed base from top to bottom successively, suspender cantilever and block, nut coordinates with bolt fastening to suspender cantilever and fixed base.
Gap between above-mentioned fixed base and block equals the thickness of suspender cantilever or is greater than the thickness 0.1mm-3mm of suspender cantilever.
The fixed structure of above-mentioned vehicular sideview suspender comprises a set of screw bolt and nut or two cover screw bolt and nut; A set of screw bolt and nut comprises the bolt and the nut that match each other, the conventional means pad of also arranging in pairs or groups, and common combination is used.
When the perforate size of above-mentioned block upper bolt hole should be able to ensure to use torque spanner, spanner nut sleeve passes through smoothly.
Above-mentioned fixed base be shaped as U-shaped.
Above-mentioned block be shaped as U-shaped.
The utility model has the advantages that:
1, the utility model only needs to increase block and can effectively prevent that suspender from coming off, and prevents bolt falling, reduces driving risk, increases travel safety.
2, the utility model is simple in structure, and realizability is higher, can realize without increasing other tooling devices.

Fig. 1 is the utility model embodiment one plan view;
Fig. 2 is the utility model embodiment one sectional view;
Fig. 3 is the utility model embodiment two plan view;
Fig. 4 is the utility model embodiment two sectional view.
Wherein: 1-suspender cantilever; 2-fixed base; 3-bolt; 4-block; 5-nut; 6-pad.
Embodiment
Embodiment one, as depicted in figs. 1 and 2, a kind of fixed structure of vehicular sideview suspender, comprise fixed base, bolt, nut and block, suspender cantilever is fastened on the top of fixed base by screw bolt and nut, fixed structure also comprises the block that is positioned at suspender cantilever top, fixed base and block are welded on mounting plane, on block, be provided with bolt hole, the size of bolt hole can make bolt head pass through, preferably, when bolt hole perforate size in block place should be able to ensure to use torque spanner, spanner nut sleeve passes through smoothly.The screw rod of bolt is from top to bottom successively by block, suspender cantilever and fixed base, nut coordinates with bolt fastening to suspender cantilever and fixed base, the lower surface of bolt head is against the upper surface of suspender cantilever, between the upper surface of nut and the lower surface of fixed base, is also provided with pad.
Gap between fixed base and block determined by the size of suspender cantilever, and the gap between general fixed base and block equals the thickness of suspender cantilever or than the large 0.1mm-3mm of the thickness of suspender cantilever.The shape of fixed base and block adopts U-shaped, also can adjust according to the shape of suspender cantilever.
Embodiment two, as Fig. 3 and 4, a kind of fixed structure of vehicular sideview suspender, fixed base is fixed on mounting plane, suspender cantilever is fastened on the below of fixed base by bolt and nut, fixed structure also comprises the block that is positioned at suspender cantilever below, block is fixed on mounting plane, on block, offer bolt hole by standard, the size of bolt hole can make the head of bolt pass through, the screw rod of bolt is from top to bottom successively by block, suspender cantilever and fixed base, and nut coordinates with bolt fastening to suspender cantilever and fixed base.
In above-described embodiment, bolt and nut can adopt multiple parallel connections, the bolt and nut and the pad that adopt many covers to work in coordination simultaneously, and when bolt and nut quantity is more, if nut comes off, multiple bolts also can bear more radial shear power.
The utility model utilizes original fixed base, bolt and nut, by increasing block, form a bolt, fixed base, the Trinitarian effect of contraction of block, after bolt and nut is loosening, suspender cantilever can be subjected to displacement under the impact of shock loads and alternate load, makes suspender cantilever to radial shear power of bolt; Now bolt does not bear longitudinal loading, longitudinal loading changes radial shear power into, also can retrain bolt by overhang to the shearing force of bolt does not upwards beat and drops, keep the original position of suspender substantially constant, the utility model constrains in suspender cantilever on the vehicle of operation by block, bolt (without nut), fixed base within the regular hour, prevent that suspender from coming off, be resumed until bolt connects.
