Running vehicle is not only done by bike, the important utensil of amusement and recreation and motion especially, wherein the trailers of trailer after bicycle in countries such as America and Europes, all the fashion especially in recent years.Trailers can be used for manned or pet.But existing trailers is when trailer brakes, brake part is more, complex structure, brake is loaded down with trivial details, in brake process, be easy to occur singly to stop wherein phenomenon on one side, trailers can be caused to topple over, meanwhile, when trailers is in stop action, easily to slide, be easy to the children in trailers or pet are caused danger.
Utility model content
For solving the problems of the technologies described above, the utility model provides to stop and stops trailers convenient to both.
The utility model solves the technical scheme that its technical matters adopts: stop and stop trailers convenient to both, it comprises unitized frame; On described unitized frame, two ends are provided with two wheels, and the rear side of the bottom of described unitized frame is connected with foot piece by foot-operated extension spring, and described foot piece is connected with traction link, and the end of described traction link is connected with brake iron and props up; Described wheel is provided with brake disc; Hub between two described wheels is welded with brake iron plate respectively near the position of two ends brake disc; Described brake iron props up and is hinged on brake iron plate by attaching parts; Described brake iron props up and brakes between iron plate and is also provided with brake extension spring, for towing brake iron Zhi Kawei; Also strut bar is provided with near the front side pillar of described vehicle frame; The pillar left and right sides, front side of described vehicle frame is welded with connection iron plate respectively; The two ends of described strut bar are hinged on by attaching parts and connect on iron plate; Described strut bar is also provided with near the position connecting iron plate and supports extension spring and be connected on the pillar of front side by supporting extension spring.
The position that the two ends of described strut bar are hinged with being connected iron plate is provided with arc pad.
Principle of work: during brake, when foot piece is trampled by foot, pulls traction link, causes brake iron and props up under the effect of attaching parts with brake extension spring, rotate, stick in two brake discs in semi arch, two wheel simultaneous brakes are moved; During un-brake, foot piece, under the effect of foot-operated extension spring, is returned to initial position, and the iron that brakes props up also under the effect of brake extension spring, also returns to initial position; During stop, hand is exerted oneself to strut bar, strut bar by be connected the hinged of iron plate and rotate to lower limit site around front side pillar, support is carried out to trailers and fixes; During traveling, strut bar is firmly folded back bottom of frame by hand, by support extension spring, strut bar is fixed on the position in upper limit site; Spacing to strut bar is realized by arc pad.
The beneficial effects of the utility model: of the present utility model stopping stops trailers convenient to both, its brake structure is very simple, decreases the loaded down with trivial details action of trailers when braking; Because brake acts on rear wheel simultaneously, for two ends interlock is braked simultaneously, the problem that overcoming singly stops topples over; , by the folding realization of strut bar, trailers is fixed meanwhile, but also does not affect the normal traveling of bicycle, make bicycle when stopping, the dangerous situation slided can not occur; Make trailers more convenient to use and comfortable, safety have also been obtained great guarantee.
