Abstract
The utility model relates to a dodecagonal flange face bolt. The dodecagonal flange face bolt comprises a bolt head, a flange plate and a screw rod. The bolt head, the flange plate and the screw rod are sequentially connected, the bolt head is a dodecagonal bolt head, and glue is arranged in the middle of the screw rod. According to the dodecagonal flange face bolt, a torsion contact surface can be dispersed, local stress can be reduced, service life of the whole dodecagonal flange face bolt can be prolonged, the phenomenon of falling off caused by loosening can not occur in the process of use, and therefore use is convenient and safe.
Description
Technical field
The utility model relates to the fastening piece that a kind of automobile is used, particularly a kind of bihexagonal head screw of motor car engine locking usefulness.
Background technique
Along with the development of science and technology, the progress of technology, automobile product makes rapid progress, and for people's everyday life must almost become indispensable articles for use, automobile each component part when design all is pre-set according to designing requirement, with link and fastening piece assembling.These component parts, link and fastening piece are used for guaranteeing Security and the travelling comfort of Vehicle Driving Cycle jointly.But because Vehicle Driving Cycle is after a period of time, these parts of reason, link and the fastening pieces such as, tire wear impaired owing to severe jolt, chassis part that parts depreciation, road uneven cause produce mass change.In case producing mass change just may produce such as safety problems such as abnormal tyre wearing and tearing, parts depreciation quickening, in the process of moving unstable, oil consumption of vehicle increase.In maintenance during dismounting, need to fastening piece for example bolt pull down, being dismounted for multiple times can cause for example thread failure of bolt of fastening piece, easily causes resonance and fatigue ruption, affects the working life of product.Along with the expansion of domestic automobile consumption market and the people day by day diversification with the car theory, must there be renewal, Fastener products more fully in the market that tackle better continuous variation, for the Consumer creates finer, vehicle safety more easily.For the large sized bolt of engine interior connected fastening piece, hexagonal flange can not bear the moment that screws installation, and the failure mode such as can cause that the diagonal angle skids in advance assembles required moment higher, and the stability of assembling and moment of torsion conformity can't guarantee.
The model utility content
The purpose of this utility model provides a kind of bihexagonal head screw, and is a kind of simple in structure, easy to use safer, to solve the problem of prior art.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of bihexagonal head screw comprises a bolt head, a flange plate and a screw rod, and described bolt head, flange plate are connected with screw rod and are connected, and described bolt head is 12 corner bolt heads.
According to the described bihexagonal head screw of the utility model preferred embodiment, the centre of described screw rod arranges gluing.
Since adopted above technological scheme, so that the utlity model has following advantageous effect:
The first, the utility model adopts the bihexagonal design, can disperse the moment of torsion surface of contact, reduces localized stress, prolongs the working life of whole part;
The second, the utility model adopts the form of gluing to carry out locking processing, and the phenomenon that comes off because becoming flexible, the Security that has improved whole assembly in use can not appear in product like this.
Description of drawings
Fig. 1 is the structural representation of model utility;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model;
Please refer to Fig. 1 and Fig. 2, a kind of bihexagonal head screw, comprise a bolt head 10, a flange plate 20 and a screw rod 30, described bolt head 10, flange plate 20 are connected with screw rod sequentially and are connected, and described bolt head 10 is 12 corner bolt heads, and head type adopts the bihexagonal form, in assembly process, can disperse the moment of torsion surface of contact, reduce localized stress, moment is higher, guarantees stability and the moment of torsion conformity of assembling; The form that in addition gluing 40 is set in the centre of described screw rod 30 is carried out locking processing, and the phenomenon that comes off because of loosening in use can not appear in product like this.
Since adopted above technological scheme, so that the utlity model has following advantageous effect:
The first, the utility model adopts the bihexagonal design, can disperse the moment of torsion surface of contact, reduces localized stress, prolongs the working life of whole part;
The second, the utility model adopts the form of gluing to carry out locking processing, and the phenomenon that comes off because becoming flexible, the Security that has improved whole assembly in use can not appear in product like this.
Above disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should drop in the protection domain of the present utility model.
