Abstract
The utility model relates to a novel structure of the sand bowls and the shaft sleeves of bicycles. The original sand bowls and shaft sleeves are all round, the sand bowls and the shaft sleeves adopt tight fit to be fixedly connected together, bringing inconvenience to maintenance and disassembly. Now the outer margin of the sand bowl (1) and the inner edge of the shaft sleeve (2) are changed into a non-circular shape, adopting key-type connection or ellipse-type connection, and the assembly relation is movable fit, thus the sand bowl (1) and the shaft sleeve (2) are fixed together and are also convenient to be disassembled.
Description
The utility model relates to a kind of bicycle accessories, promptly a kind of quick detachable bicycle antero posterior axis bearing carrier ring.
Bearing carrier ring on the bicycle antero posterior axis is made up of sand bowl and axle sleeve, wherein, the sand bowl is by with the close fit of axle sleeve or the assembly relation of interference fit is fixed together, bearing contacts with the sand bowl and can be by adjusting the gap of axle bumper and bearing, and the flexible slip of realization bearing and sand bowl, but sand bowl and axle sleeve then are buckled together tightly, and can not slide relative.Sand bowl and this of axle sleeve are connected, though have many good qualities, dismantle very difficultly, that is to say, the sand bowl is difficult to take off from axle sleeve.Because often friction between sand bowl and bearing, wearing and tearing easily need in time to change.Therefore, dismounting difficulty has just become a big shortcoming of existing connecting mode.
The purpose of this utility model provides a kind of bicycle antero posterior axis axle sleeve and sand bowl of convenient disassembly.
Technical scheme: this bearing carrier ring is made up of sand bowl and axle sleeve, and wherein, sand bowl inner edge still is original circle, and outer rim then is non-circular, and the inner edge of axle sleeve also adopts the running-fit assembly relation with the outer rim of sand bowl.
Said non-circle or not exclusively circular can adopt sand bowl outer rim to be provided with boss, and circle is provided with the concave station that matches in the axle sleeve, and promptly the two adopts the key ways of connecting.
Above-mentioned key ways of connecting, also extending to sand bowl outer rim and axle sleeve inner edge is oval-shaped connecting mode.
Introduce two kinds of embodiment below in conjunction with accompanying drawing:
Fig. 1 is the front view of first kind of embodiment, and Fig. 2 is its left view.
Fig. 3 is second kind of embodiment front view.
As shown in Figure 1 and Figure 2, on sand bowl (1) outer rim, be provided with two keypads (3), be provided with the keyway (4) that matches on the inner edge of axle sleeve (2), the two adopts the running-fit tolerance, and installing/dismounting is all very convenient.
Sand bowl (1) outer rim as shown in Figure 3 and axle sleeve (2) inner edge all adopt ellipse, and are running-fit, easy installation and removal, and also intensity is higher.
Adopt the axle sleeve sand bowl of such scheme, overcome the shortcoming of prior art, and can serve the same role.
Claims (3)
1, a kind of quick detachable bicycle antero posterior axis bearing carrier ring is made up of sand bowl (1) and axle sleeve (2), it is characterized in that: the inner edge of the outer rim of sand bowl (1) and axle sleeve (2) is non-circular, adopts the running-fit assembly relation between the two.
2, quick detachable bicycle antero posterior axis bearing carrier ring according to claim 1 is characterized in that: the inner edge of the outer rim of said sand bowl (1) and axle sleeve (2) can adopt key to be connected.
3, quick detachable bicycle antero posterior axis bearing carrier ring according to claim 1, it is characterized in that: the inner edge of the outer rim of said sand bowl (1) and axle sleeve (2) can be made into ellipse.
