Description

A kind of bicycle quick-detaching

Technical field:

The utility model relates to a kind of bicycle assembly, refers to especially a kind of in order to the quick detach with bicycle drive shaft and crotch assembling.

Background technology:

As shown in Figure 1, 2, 3, the described bicycle quick-detaching 10 of No. 5622412 Patent Case of the U.S., have an axostylus axostyle 40; One is sleeved on the outer housing 12 of a contiguous block 43 of this axostylus axostyle 40; One vertical direction along this axostylus axostyle 40 is located in the rotating cam 13 between housing 12 and contiguous block 43; One is set in this rotating cam 13 and is positioned at the outer control lever 60 of this housing 12; And the nut 100 be threaded with a thread segment 42 of axostylus axostyle 40.The rotating cam of telling 13 has large-diameter portion 131; From large-diameter portion 131 along one extend axially and with the cam 132 of described large-diameter portion 131 bias; From cam 132, along this, extend axially and the minor diameter part 133 concentric with large-diameter portion 131; Reach from minor diameter part 133 along this axially extended tooth-strip part 134.Described control lever 60 has and the intermeshing scallop 141 of described tooth-strip part 134.When rotating cam 13 being arranged in to housing 12 with contiguous block 43, described cam 132 is positioned at the perforation 112 of contiguous block 43, and described tooth-strip part 134 protrudes a side of housing 12, intermeshing in order to the scallop 141 with control lever 60.

During use, described bicycle quick-detaching 10 is installed between flower-drum 30 and two crotch (31,32), when pulling control lever 60, just can allow cam 132 drive described axostylus axostyle 40 linear displacements, and then reach the application target that makes described two crotch (31,32) and flower-drum 30 complete packing or unclamp, yet, although this quick detach 10 has above-mentioned use function, in fact still there is lower column defects:

One, because control lever 60 is that monolateral driving rotating cam 13 rotates, because driving force concentrates on tooth-strip part 134, therefore make rotating cam 13 unbalance stress, cause easily producing and rocking in rotation process, there are operation steadiness, the not good defect of smoothness.

Two,, as described in first, because rotating cam 13 easily produces and rocks in rotation process, the mobile accuracy of corresponding described axostylus axostyle 40 is just low.

The utility model content:

The purpose of this utility model provides a kind of with regard to being the weak point existed for prior art can improve operation steadiness, smoothness, and can improve the quick detach that axostylus axostyle moves accuracy.

For achieving the above object, the technical solution adopted in the utility model is:
