Abstract
The utility model relates to a push-drag dolly with a rotatable front wheel and shockproof rear wheels. The push-drag dolly comprises a rack, a handle pushing tube, a front collision-avoiding protection tube and a rear collision-avoiding protection tube, wherein fixing pieces and damping connection pieces are arranged on the rack. The push-drag dolly further comprises a front wheel rotating device and a rear wheel damping device, wherein the front wheel rotating device comprises a rotary front wheel set which is arranged on the front wheel and located on the rack through a knot. The rear wheel damping device comprises a support running tube, and rear wheels are arranged on two ends of the support running tube, and dampers are arranged on the support running tube. The push-drag dolly is simple in structure, and the front wheel is increased in rotation, and 360-degree rotation of the front wheel can be achieved. In the push process, the driving direction can be arbitrarily controlled. Due to addition of the rear wheel dampers, driving is stable and safe, discomfort on human body due to shocks of the bicycle drag dolly in driving can be avoided, and the bicycle drag dolly connected on the rear of a bicycle can be prevented from rolling over on one side at a sharp turn of the bicycle.
Description
Technical field
The utility model relates to the trailers field, and the bicycle that especially relates to a kind of front-wheel rotation rear wheel vibration damping is evaded car.
Background technology
In western countries such as America and Europes, bicycle is not only being done running vehicle, also is the important utensil of amusement and recreation and motion, and wherein trailers is all the fashion especially in recent years.Trailers can be used for hauling children, also can be used as children trolley uses, but trailers direction when using the go-cart function is difficult to control system at present, the human discomfort that brings to human body because of the vibrations in the driving process of trailers and when the bicycle sharply turning simultaneously, the potential safety hazard when causing the back trailers rollover that is connected to bicycle etc. to cause child seats.
Summary of the invention
In order to overcome defects, the utility model provides a kind of front-wheel rotation rear wheel vibration damping to evade car, solve present trailers direction when using the go-cart function and be difficult to control problem processed, overcome simultaneously trailers because of the vibrations of travelling, when the shortcoming of the human discomfort that brings to human body and bicycle sharply turning, cause the back trailers rollover that is connected to bicycle.Increase trailers damping effect in the process of moving, driving stability safety is safer more relieved when child seats.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of front-wheel rotation rear wheel vibration damping is evaded car, comprise vehicle frame, push away the handle pipe, front Anti-bumping protection pipe and rear anti-crash protective tube, vehicle frame is provided with connecting element one and shock-damping connector, also comprise fore wheel rotating device and rear wheel damping device, fore wheel rotating device comprises the front wheels of rotation, wheels are installed on the front-wheel before the rotation, wheels are installed on the vehicle frame by knob before the rotation, rear wheel damping device comprises that supporting walking manages, and supports walking pipe two ends and is provided with trailing wheel, supports the pipe of walking and is provided with bumper; Bumper is vertically mounted on and supports on the walking pipe, and bumper has 2; Front-wheel connects the front wheels of rotation by Quick-dismantle component; Vehicle frame upper end is provided with a day fluffy pipe, is connected by rear supporting tube between described day fluffy pipe and vehicle frame; Pushing away the handle pipe is fixed on the rear supporting tube by knob; Front Anti-bumping protection pipe is provided with the connecting element two that is complementary with connecting element one.
The beneficial effects of the utility model are: simple in structure, the single car of evading of front-wheel rotation rear wheel vibration damping has increased the front-wheel rotation, can realize front-wheel 360 degree rotations, can arbitrarily control travel direction in the implementation process; Increased the rear wheel vibration damping device, driving stability safety when having avoided human discomfort that trailers brings to human body because of the vibrations of travelling and bicycle sharply turning, avoids being connected to the trailers rollover of bicycle back.
