Abstract
The utility model relates to a bicycle trailer convenient for folding and unfolding. The bicycle trailer comprises an integral frame, wherein a supporting shaft is arranged below the integral frame; two wheels are respectively arranged on the two ends of the supporting shaft; an arc-shaped handle is rotatably connected on the front end of the integral frame; the two sides of the arc-shaped handle are respectively connected with an upper supporting travelling piece by a connecting piece and a connecting shaft; the upper supporting travelling piece and a lower supporting travelling piece are connected by the connecting piece and the connecting shaft; the lower supporting travelling piece and the rear end of the integral frame are connected by the connecting piece and the connecting shaft which are welded on the integral frame; a pneumatic spring is arranged between the upper supporting travelling piece and the integral frame; and the two ends of the pneumatic spring are respectively connected with the upper supporting travelling piece and the integral frame by the connecting shaft. The bicycle trailer convenient for folding and unfolding has a simple structure, and can obviously increase the fussy actions when the bicycle trailer unfolds the frame; among the fussy unfolding actions, the insertion and fixation for a locking device is often forgotten, so a damping system is increased for avoiding the discomfort, which is caused by the vibration in the travelling process of the bicycle trailer, to the human body.
Description
Technical field
The utility model relates to a kind of trailers technology, especially relates to a kind of trailers that can launch and have shock-absorbing function automatically.
Background technology
Not only doing running vehicle by bike in countries such as America and Europes, the important utensil of amusement and recreation and motion especially, wherein the trailers of trailer behind bicycle was all the fashion especially in recent years.Trailers can be used for manned or pet.When the trailers that will fold is opened, waste time and energy, because the process of opening is more loaded down with trivial details, tend to forget the plug-in mounting safety lock sometimes, the phenomenon that folds automatically appears when causing using; Trailers is because of the vibrations of going, the shortcoming of the human discomfort that can bring to human body, and when the bicycle sharply turning, possibly cause the trailers that is connected the bicycle back rollover to occur.
Summary of the invention
The utility model technical matters to be solved provides a kind of trailers that has pneumatics, and it has overcome more loaded down with trivial details action of opening and folding and appearance uncomfortable and phenomenons such as can turning on one's side.
The utility model solves the technical scheme that its technical matters adopted: a kind of trailers that conveniently folds and open; Comprise unitized frame; The below of unitized frame is provided with pivot shaft; The two ends of pivot shaft are separately installed with two wheels, and at the front end of the unitized frame bowhandle that is rotationally connected, the bowhandle both sides are connected through second attaching parts and the 5th adapter shaft and the last support part of walking respectively; Last support walking part is connected with the 3rd adapter shaft through first attaching parts with the following walking part that supports; Following support walking part is connected with the 4th adapter shaft through the 3rd attaching parts that is welded in unitized frame with the rear end of unitized frame, and described going up between support walking part and the unitized frame is provided with pneumatic spring, and the two ends of pneumatic spring are connected with unitized frame with last support walking part with second adapter shaft through first adapter shaft respectively.
Lock vehicle frame for ease, described going up supported the walking part and is provided with the fixing and locking device between support walking part down.
In order to make comfortable when in use and the phenomenon of can not turning on one's side, described pivot shaft top is provided with shock absorption device; Further: described shock absorption device comprises the bumper that is connected between pivot shaft and the unitized frame, and an end is fixedly connected on pivot shaft one end through the 6th adapter shaft and the 4th attaching parts bonded assembly pipe link that is fixedly connected on unitized frame.
The beneficial effect of the utility model is: simple in structure, can obviously increase trailers loaded down with trivial details action when vehicle frame launches, and safer more relieved when child seats, because in loaded down with trivial details expansion action, tend to forget plug-in mounting fixing and locking device.In use avoiding folding automatically causes children injured; With can obviously increase trailers damping effect in the process of moving; Driving stability safety; When having avoided human discomfort that trailers brings to human body because of the vibrations of going and bicycle sharply turning, avoid being connected the trailers rollover danger of bicycle back.

The specific embodiment
A kind of trailers that conveniently folds and open shown in Fig. 1-4; Comprise unitized frame 20; The below of unitized frame 20 is provided with pivot shaft 17; The two ends of pivot shaft 17 are separately installed with two wheels 16, and at the front end of unitized frame 20 bowhandle 15 that is rotationally connected, bowhandle 15 both sides are connected through second attaching parts 10 and the 5th adapter shaft 9 and the last support part 8 of walking respectively; Last support walking part 8 is connected with the 3rd adapter shaft 5 through first attaching parts 4 with the following walking part 6 that supports; Following support walking part 6 is connected with the 4th adapter shaft 7 through the 3rd attaching parts 12 that is welded in unitized frame 20 with the rear end of unitized frame 20, and described going up between support walking part 8 and the unitized frame 20 is provided with pneumatic spring 1, and the two ends of pneumatic spring 1 are connected with unitized frame 20 with last support walking part 8 with second adapter shaft 3 through first adapter shaft 2 respectively; Described upward support walking part 8 and following 6 of the parts of walking that support are provided with fixing and locking device 11; Described pivot shaft 17 tops are provided with shock absorption device; Described shock absorption device comprises the bumper 13 that is connected between pivot shaft 17 and the unitized frame 20, and an end is fixedly connected on pivot shaft 17 1 ends through the 6th adapter shaft 18 and the 4th attaching parts 19 bonded assembly pipe links 14 that are fixedly connected on unitized frame 20.
This routine course of action is; When trailers normally uses; Open trailer to open mode (as shown in Figure 2) by collapse state (as shown in Figure 3) through bowhandle 15, when bowhandle 15 opened to 45 °, pneumatic spring 1 can stretch out automatically to be held last support walking part 8 in 20 minutes until opening the shape body with unitized frame; Plug fixing and locking device 11 this moment, guarantee that trailers is in open mode all the time; The pivot shaft 17 that connects wheel is stressed, through bumper 13 and the rotation of the 6th adapter shaft 18 with the 4th attaching parts 19 of fixing and unitized frame 20 rear ends, thereby has reached trailers damping effect and safety in the process of moving.
