Description
Technical field
The utility model relates to a kind of attached operating mechanisms of delivery vehicle, more specifically, it relates to which a kind of single wheel drags
Chinese herbaceous peony pitches bulb bindiny mechanism.
Background technique
With the development of economy and social progress, bicycle is changed by the past simple vehicles more to be undertaken
Body-building, Leisure Function multi-purpose tool, various regions have a large amount of cycling fans individually or form a team to carry out it is different away from
From travelling, such as spring and autumn just have many people like cycle outing.Since distance of riding is longer, bicyclist, which is often stopped, to stop
Breath or even camp out, therefore more luggage would generally be carried when trip.If luggage is too many, can not be carried on bicycle,
People will use trailer to carry, and trailer is moved ahead after hanging over bicycle by bicycle traction, and when stopping rest, trailer can also be used
Make the platform of placement beverage, food and other items.Existing trailer is usually single-wheel on the market, and trailer wheel is by front fork and voluntarily
The rear-wheel central spindle of vehicle connects.Since bicycle rear central spindle inconvenience is dismantled, the connection between existing trailer front fork and rear-wheel central spindle
Structure is typically all to be constituted and installing fixing piece additional at rear-wheel central spindle both ends, such as common are nut fixed structure, bulb
Connection structure etc., but require respectively to dismount the fixing piece at rear-wheel central spindle both ends when the dismounting of these structures, it could be final
The separation or connection of trailer and bicycle are completed, operating process is more troublesome, and the disassembly efficiency between front fork and rear-wheel central spindle is lower.
Therefore, existing one-wheel trailer need to improve, and to be more convenient, quickly dismounting between front fork and rear-wheel central spindle be completed, into one
Step simplifies operation, improves separation or the joint efficiency of trailer and bicycle.
Utility model content
Connection structure between existing trailer front fork and rear-wheel central spindle is typically all solid by installing additional at rear-wheel central spindle both ends
Determine part and constitute, the disassembling operations trouble between front fork and rear-wheel central spindle, efficiency is lower, and to overcome this defect, this is practical new
Type provides a kind of simplified operation, is more convenient, quickly completes dismounting between front fork and rear-wheel central spindle, improve trailer with voluntarily
