Have inside flange inside the outer end of described sleeve pipe, described push rod has flange portion, and described spring is located between described flange and flange portion, and the two ends of described spring are connected with described flange and flange portion respectively.
The advantage that the present invention has and good effect are: flower-drum assembly of the present invention is integrated with for the structure by wheel lock, this structural allocation is hidden, is not easily destroyed, and safety performance is good, and can not impact the profile of bicycle, make the profile of bicycle more brief generous.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, axle; 1-1, centre hole; 1-2, radial direction through hole; 2, bearing; 3, flower-drum; 3-1, circumferential teeth groove; 4, lock body; 5, retractable lock rod; 6, wedge; 7, sleeve pipe; 8, push rod; 9, spring.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of wheel hub assembly with wheel lock function, comprises axle 1, bearing 2 and flower-drum 3.Described flower-drum 3 is fitted in described axle 1 by bearing 2.Flower-drum 2 and axle 1 concentric, axle 1 is pitched with the car of bicycle and is connected, and flower-drum 3 is for connecting spoke.
In described axle 1, there is axial centre hole 1-1.In the present embodiment, there is in axle 1 centre hole at through axle 1 two ends.The inner side, aperture (aperture, one end) of described centre hole 1-1 is provided with lock body 4.The front end of described lock body 4, the outside being positioned at described centre hole 1-1 have lockhole.The rear end of described lock body 4 is connected on the retractable lock rod 5 inside described centre hole 1-1.The connection structure of above-mentioned lock body 4, lockhole and retractable lock rod 5 principle of work is can learn in lock on the market, belongs to prior art, retractable lock rod 5 can be made to carry out expanding-contracting action by the key inserting lockhole.
Described retractable lock rod 5 connects wedge 6.In described axle 1, the position corresponding with described wedge 6 be provided with radial direction through hole 1-2, i.e. the interior outside of the through axle of radial direction through hole 1-2 1.Be provided with sleeve pipe 7 in described radial direction through hole 1-2, in the present embodiment, sleeve pipe 7 is fitted in the radial direction through hole 1-2 of axle 1 by screw thread.Be fitted with push rod 8 in described sleeve pipe 7, between described sleeve pipe 7 and described push rod 8, be provided with the spring 9 making described push rod 8 hold out against wedge 6.The medial surface of described flower-drum 3, the position of corresponding described push rod 8 are provided with circumferential teeth groove 3-1.
In the present embodiment, the inner side of described radial direction through hole 1-2 has negative thread, has outside thread outside described sleeve pipe 7.Have inside flange inside the outer end of described sleeve pipe 7, described push rod 8 has flange portion, and described spring 9 is located between described flange and flange portion, and the two ends of described spring 9 are connected with described flange and flange portion respectively.
Method of work
Under bicycle mode of operation, push rod 8 is in the state of retraction inside axle 1, and the top of push rod 8 does not contact with the circumferential teeth groove 3-1 inside flower-drum 3, and flower-drum 3 can rotate by phase center roller 1, the wheel normal operation of bicycle.When needing to carry out locked to wheel, utilize the key inserting lockhole to make retractable lock rod 5 control wedge 6 to move axially, push rod 8 radially ejects by the wedge 6 moved axially, finally make the circumferential teeth groove 3-1 clamping inside the top of push rod 8 and flower-drum 3, axle 1 is relative with flower-drum 3 locked, to realize the locking of wheel.
