[specific embodiment]

A kind of brake structure of perambulator comprises a set of wheels 2, a slide group 4 and a driven unit 5.

Set of wheels 2 is made of axis 21, wheel seat 22 and wheel 23, and this axis 21 is fixedly connected to pin pipe 20 lower ends, be provided with in the bottom of this axis 21 can with wheel seat 22 clips and clip groove 211 circlewise.

Wheel seat 22 and axis 21 sockets, on this wheel seat 22, be provided with a clip shell fragment 221, this clip shell fragment 221 is cooperated with clip groove 211 on the axis 21, and make this wheel seat 22 be subjected to the restriction of clip groove 211 and be unlikely disengaging, can also rotate this structure such as the U.S. the 5th for center shaft according to this axis 21,276, No. 941 patent cases, this wheel seat 22 can have antivibration spring 3 by device, is positioned at the amount of movement that wheel shaft 24 that this antivibration spring 3 downsides articulate wheel 23 is transmitted with absorption.

Wheel 23 utilizes wheel shaft 24 to be articulated in the both sides of wheel seat 22 in the middle of present embodiment, and wheel 23 is provided with blocking part 231.Blocking part 231 can be the brake fluted disc of ring-type, also can be the groove (do not draw among the figure, decide on the actuator shape that is mated) of ring-type.

Slide group 4 comprises packing cover 41, sliding sleeve permanent seat 42, brake shoe 43 and a returning spring 44.Wherein this sliding sleeve permanent seat 42 is fixed on the pin pipe 20, can overlap 41 sockets for packing slides, in addition brake shoe 43 is to be positioned at this packing to overlap 41 lower edges and slidably be socketed on the pin pipe 20, this brake shoe 43 is to be pressed and it is moved down by packing cover 41, and by the elastic recovery original position of returning spring 44, this brake shoe 43 comprises build-in protuberance 431, this build-in protuberance 431 and engage with the blocking part 231 of wheel 23 and to form brake.

Driven unit 5 is to be articulated on the pin pipe 20, has a brake position and a releasing position, and this driven unit 5 comprises a motion arm 51, and this motion arm 51 is fixing towards without hindrance locus, the perambulator outside, so that the user to be provided handled easily.Again with reference to figure 3, Fig. 4, driven unit 5 is located at the top position of slide group 4, when the user presses down the motion arm 51 of driven unit 5, this driven unit 5 will be suppressed sliding sleeve group 4, the brake shoe 43 of sliding sleeve group 4 is moved down via packing cover 41, and, form a brake state by the blocking part 231 of the build-in protuberance 431 clip wheels 23 of brake shoe 43.Simultaneously, by the compacting of this driven unit 5, make it remain in brake state (as shown in Figure 4); And when driven unit 5 moved to the releasing position, Slide Group 4 is returned back to by the elasticity of returning spring 44 kept in touch with driven unit 5 or driven unit 5 gets position contacting when mobile.

Because the driven unit 5 of this creation is to be articulated on the pin pipe 20, so, rotate and keep on same direction and the position, and make the comfort feature that provides the user can operate brake structure on single position is provided with set of wheels 2, must be with set of wheels 2 rotations.Device locating slide sleeve 45 on the utility model slide group 4 is controlled set of wheels 2 rotatable states or is become directed state by this locating slide sleeve 45 in addition.
