Abstract
The utility model discloses an anti -loose bolt, it includes: the shank of bolt, the bolt head is settled in the end of shank of bolt, wherein, the shank of bolt has spline segment and screw thread section. Wherein, the spline period number of shank of bolt in the bolt head with between the screw thread section. The utility model discloses an anti -loose bolt, simple structure, processing, simple to operate, the fastening of the vehicle chassis part after having strengthened connecting is stable, has promoted the security performance of whole car.
Description
Technical field
The utility model relates to auto parts machinery technical field, relates in particular to a kind of for preventing vapourThe check bolt of chassis superstructure loosening.
Background technology
Bolt is a kind of conventional securing member, often adopts bolt pair in existing auto parts machineryThe assembly of automobile is fixed installation, still, along with the vibration of travelling of car load, makes usingBolt in journey easily occurs loosening, thereby the operational failure of bringing is brought loss to user,And then affect the driving safety of car load, there is potential safety hazard.
In view of current situation, for the designer of automotive field, need to develop differenceStructure and multi-form bolt, required to meet on different application field and different installation siteThe anti-loosening property of wanting, avoids occurring loosening problem after construction bolt, to meet the safety of automobileRequirement.
Summary of the invention
The purpose of this utility model is exactly to achieve these goals, and a kind of check bolt is provided,It is simple in structure, and the fastening of the automobile chassis parts after connection strengthened in processing, easy for installationStability, has promoted the security performance of car load.
For realizing above-mentioned purpose of the present utility model, the utility model provides a kind of check bolt,It comprises: shank of bolt; Bolt head, is placed in the end of shank of bolt; Wherein, described shank of boltThere is spline segment and thread segment.
Wherein, the spline segment of described shank of bolt is between described bolt head and described thread segment.
Wherein, the external diameter of described spline segment is greater than the external diameter of described thread segment.
Wherein, described bolt head has flange.
Compared with prior art, check bolt tool of the present utility model has the following advantages:
1, check bolt of the present utility model is by shank of bolt top, spline segment being set, therebyStrengthen the fastening stability of the automobile chassis parts of its connection, the security that has improved automobile.
2, check bolt of the present utility model is simple in structure, and spline is easy to process, easy for installation,Low cost of manufacture.
Below in conjunction with accompanying drawing, the utility model is elaborated.
Brief description of the drawings
Fig. 1 is the front view of check bolt of the present utility model;
Fig. 2 is that the A-A of check bolt shown in Fig. 1 is to view;
Fig. 3 is that check bolt of the present utility model is installed on the knot on vehicle shock absorber and knuckleStructure schematic diagram.
Detailed description of the invention
As shown in Figure 1 and Figure 2, for the utility model provide for connecting automobile chassis topThe structural representation of the check bolt of part. As seen from the figure, check bolt of the present utility model comprises:Shank of bolt 1; Bolt head 2, is placed in the end of shank of bolt 1; Wherein, shank of bolt 1 hasSpline segment 5 and thread segment 4.
Concrete, as shown in Figure 1 and Figure 2, check bolt of the present utility model comprises shank of bolt1 and bolt head 2, bolt head 2 is installed on the end of shank of bolt 1, and shank of bolt 1 has splineSection 5 and thread segment 4, spline segment 5 between bolt head 2 and thread segment 4, in addition, spiral shellTightening latch 1 front end also has polished rod section 3.
By spline segment 5 is set on shank of bolt 1, make to adopt locking spiral shell of the present utility modelWhile tying the automobile chassis parts that connect, the fastening stability between bolt and vehicle chassis component strengthens,While having solved available technology adopting without the bolt connecting base plate parts of spline segment, bolt is easily looseningProblem, thereby improved the security performance of automobile.
Wherein, the external diameter of the spline segment 5 of shank of bolt 1 is greater than the external diameter of its thread segment 4, is convenient toCheck bolt of the present utility model is processed, be also convenient to adopt it to connect the each end on automobileDisk component.
And as shown in Figure 1 and Figure 2, bolt head 2 has flange 6, flange 6 is arranged on closeSpline segment 5 places of shank of bolt 1, this flange 6 is disc, it can be fixing with shank of bolt 1Connect.
Larger when adopting check bolt of the present utility model to connect on automobile chassis Oscillation AmplitudeWhen associated components, such as when connecting shock absorber 7 as shown in Figure 3 and knuckle 8, spiral shellPolished rod section 3 and the part thread segment 4 of tightening latch 1 front end stretch out in outside knuckle 8, pass through nut9 be spun on mode on thread segment 4, by bolt, shock absorber 7 and knuckle 8 be connected to oneRise. Shock absorber 7 and knuckle 8 have for through the through hole of shank of bolt 1, the cutting of this through holeThe cross section (as shown in Figure 2) of face shape and splined end 5 adapts, and makes when shank of bolt 1When spline segment 5 passes the through hole of shock absorber 7 and knuckle 8, turn to shock absorber 7, partJoint 8 connects respectively, and shank of bolt 1 can not rotate with respect to shock absorber 7, part knuckle 8,Check bolt is difficult for loosening, thus make by the shock absorber 7 of its connection and knuckle 8 itBetween fastening stable, strengthened the fastening stability that automobile connects, and then promoted the safety of car loadProperty.
In addition, check bolt of the present utility model only processes spline segment, structure letter on screw rodSingle, be easy to processing, it is also convenient to install, and manufacturing cost is also very low.
Although above the utility model is explained in detail, the utility model is not limited to this,Those skilled in the art can modify according to principle of the present utility model, therefore,All various amendments of carrying out according to principle of the present utility model all should be understood to fall into this practicalityNovel protection domain.
