The left side and the right side of the frame body are respectively connected with one iron sheet of the brake in a welded mode, the two ends of the iron support of the brake are locked to the iron sheets of the brake through L-shaped connecting pieces respectively, a brake disk is installed on the outer side of each iron sheet of the brake, a screw is connected between each iron sheet of the brake and the frame body, and a second tension spring is arranged between each screw and the corresponding L-shaped connecting piece. Through the mode, the tedious structure for braking of the bicycle trailer can be simplified, cost is reduced, an ideal braking effect can be achieved conveniently in the braking action, braking instability caused by tedious action in the braking operation and a complex structure is avoided.
Description
Technical field
The utility model relates to trailers technical field, particularly relates to a kind of trailers simple type brake.
Background technology
In countries such as America and Europes, not only doing by bike running vehicle, the important utensil of amusement and recreation and motion especially, wherein the trailers of trailer after bicycle, all the fashion especially in recent years.Trailers can be used for manned cargo-carrying or carries pet, and the brake gear of existing trailers is more loaded down with trivial details, complex structure, and cost of manufacture is high.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of trailers simple type brake, can be in the action of brake, can reach very easily desirable braking effect, avoid loaded down with trivial details action and complicated structure in brake operation to bring brake fugitiveness.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of trailers simple type brake is provided, comprise: vehicle frame body, foot piece and traction link, the upper end of described foot piece is arranged on the front end middle and lower part of vehicle frame body, one end of described traction link connects the lower end of foot piece, the other end of described traction link connects brake iron and props up, and is also provided with the first extension spring between vehicle frame body and foot piece; Described vehicle frame body each side welds a brake iron plate, the two ends that brake iron props up are locked at respectively on brake iron plate by L-type attaching parts, the outside of described brake iron plate is provided with brake disc, between described brake iron plate and vehicle frame body, be connected a screw, between described screw and L-type attaching parts, be provided with the second extension spring.
In preferred embodiment of the utility model, one end clasp joint of described extension spring is in the front end middle and upper part of vehicle frame body, and the other end clasp joint of described extension spring is in the lower end of foot piece, guarantees foot piece un-brake and the lock stability between stopping.
In preferred embodiment of the utility model, for the iron Zhi Shunli that makes to brake slips into brake disc, two ends and L-type attaching parts that described brake iron props up are welded as a whole.
In preferred embodiment of the utility model, one end clasp joint of described the second extension spring is at the polished rod position of screw, and the other end clasp joint of described the second extension spring is in the circular hole of L-type attaching parts, and the second extension spring is caught on brake iron and propped up, and plays the effect of traction.
The beneficial effects of the utility model are: the utility model is simple in structure, can obviously reduce trailers loaded down with trivial details action when trailer brakes, safer more relieved when child seats, because, while there is singly to stop wherein phenomenon on one side, can topple in brake process at part trailer, in use avoiding toppling over causes children injured, by the effect of a pin dual brake, make left and right wheels stop motion simultaneously, embody more easily traveling comfort and the stability of use.
