Fig. 3 shows the front view of the jacket assembly 300 for wheel fastener according to an embodiment of the present invention,
Fig. 4 is the top view according to the jacket assembly 300 for wheel fastener of an embodiment of the present invention.Referring now to Fig. 3
It is illustrated with jacket assembly 300 for wheel fastener of the Fig. 4 to the present embodiment.
As shown in figure 3, jacket assembly 300 includes threaded connector 301, locking piece 302, removable pin 303, oversheath 304
With locating part 305.
Threaded connector 301 is connected to wheel fastener, for installation or removing vehicle tyres fastener.Threaded connector
301 can be attachment screw.Threaded connector 301 includes top and main part.It is heavy that the top of threaded connector 301 is provided with
Hole, the depth of counterbore are less than the thickness at top.The shape of counterbore can be rule, be also possible to irregular.Preferably, it is
Convenient for manufacture, the shape of counterbore is regular.The shape of rule can be quadrangle, hexagon etc..Counterbore can be step
Shape counterbore, the step of step-like counterbore can be two layers of step, be also possible to more layers step.By taking two layers of step as an example,
Including bottom surface, First terrace and second step face.Bottom surface can be adapted to removable pin 303, and First terrace can be with locking
Part 302 is adapted to, and second step face can be adapted to oversheath.Stepped can be set in top, matches convenient for subsequent with oversheath
It closes and uses, the step at top can be corresponding with the step of counterbore.The main part of threaded connector 301 is provided with screw thread, the spiral shell
Line is adapted with the screw thread of wheel fastener, and torque is passed to wheel fastener by screw thread, to realize that wheel fastens
The installation and removal of part.
Locking member 302 is arranged in the counterbore at the top of threaded connector 301.The exterior contour of locking member 302 can be with
The shape of counterbore is adapted.For example, as shown in Figure 4 and Figure 5, the exterior contour 3021 of locking member 302 and the shape of counterbore are all
Hexagon.The counterbore of locking member 302 and threaded connector 301 can be matched using interference fit, such as press-fitting or contracting.Locking member
302 can also be fixed together with the counterbore of threaded connector 301 by other structures, such as by keyway arrangements by locking member
302 are fixed together with the counterbore of threaded connector 301.
The centre of locking member 302 is additionally provided with through-hole.The edge of through-hole has irregular tooth form.For example, such as Fig. 5 institute
Show, the edge 3022 of through-hole may include the groove of multiple non-uniform spacing settings.In Fig. 5, the edge 3022 of through-hole includes 4
The groove of non-uniform spacing setting, wherein 3 grooves are more concentrated, the groove that another groove is concentrated far from this 3.It can manage
Solution, the edge of through-hole may include the groove of more, such as 5,6 etc..Multiple grooves at through-hole edge can be other
The non-uniform spacing of form, such as the multiple grooves of setting are distributed using random number.The shape of groove is also not necessarily limited to shown in fig. 5
Smooth groove is also possible to coarse groove.The shape of unlock piece 400 must be adapted with the shape at through-hole edge, ability
Locking piece is delivered torque to, locking piece is opened.
Removable pin 303 passes through the through-hole of locking member 302, and at least part of size that removable pin 303 passes through through-hole is greater than
The size of through-hole.Removable pin 303 has different radial dimensions, for example including first size d1 and the second size d2, the first ruler
Very little d1 is less than the size of 302 through-hole of locking piece, and removable pin 303 is enabled to pass through the through-hole of locking piece 302, and the second size d2 is big
In the size of 302 through-hole of locking piece, removable pin is axially fixed in counterbore.Wherein, the first size d1 of removable pin
Not significantly less than the size of through-hole, so that the gap very little between removable pin and through-hole.The size in gap can be 1cm or so.
The cross section of removable pin be it is circular, can be rotated in counterbore.
Oversheath 304 is equipped in the outside of threaded connector 301.As shown in figure 3, oversheath 304 be threadedly coupled
The head of part 301 is adapted.Oversheath 304 is made of high strength alloy steel, makes the intensity with higher of oversheath 301.Outside
Sheath 304 can be electroplated using high anticorrosion, and wheel hub fastener is made to adapt to various severe environments.The head of oversheath 304
Portion is smooth spherical surface, so that external force tool can not destroy oversheath 304 because of skidding.Oversheath 304 and threaded connector 301
It is clearance fit, threaded connector 301 is rotated in oversheath 304.The size of oversheath 304 can be according to mesh
The size of mark wheel fastener is adjusted.It further include locating part 305 between oversheath 304 and threaded connector 301, for limiting
Axial movement of the threaded connector 301 processed in oversheath 304.Locating part 305 can be circlip, and circlip can be in various ways
It is connected on the side wall of oversheath 304.
Schematic diagram has been used to be used to illustrate structure according to an embodiment of the present application herein.It should be understood that not institute
Component be all necessary.On the contrary, it is convenient to omit fall certain structures.For example, for purposes of this application, locating part 350 not must
Must, thus can be omitted, or replace with other structures.
The jacket assembly 300 of the embodiment of the application can achieve following technical effect:
(1) has good applicability.By changing the size of 304 outer diameter of oversheath, various sizes of vehicle can be adapted to
Take turns fastener.It is compared with the wheel fastener of market routine, jacket assembly 300 is only used as exterior trim pendant, and more wheel change is not present
Fastener bring strength problem.
(2) anti-theft performance is improved.Oversheath 304 is made of high-strength alloy, and the head of oversheath 304 is smooth
Spherical surface, external force tool is not available because of skidding, can resist illegal external force and destroy；The through-hole edge of locking piece 302 has
There is irregular tooth form, a variety of different shapes can be developed, the unlock piece 400 being only adapted to through-hole edge shape could be beaten
Open jacket assembly；The first size d1 of removable pin 303 is not significantly less than the size of through-hole, so that between removable pin 303 and through-hole
Gap very little, further reduced the space of illegal tool activity；Removable pin 303 can be rotated around axis, external tool
Removable pin can not be acted on to unscrew threaded connector.
(3) duplicate protection is realized.Package assembly 304 uses high strength alloy steel and high anticorrosion is electroplated, and actually makes
In, the anti-theft performance of wheel fastener is not only increased, wheel fastener can also be made to hold and be influenced by the adverse circumstances, is improved
The service life of wheel fastener.
Although the utility model is described with reference to current specific embodiment, ordinary skill in the art
Personnel it should be appreciated that more than embodiment be intended merely to illustrate the utility model, be detached from the spirit of the present invention no
In the case of can also make various equivalent change or replacement, therefore, as long as to upper in the spirit of the utility model
State the variation of embodiment, modification will all be fallen in the range of following claims.
