Abstract
The utility model relates to the technical field of baby carriages, in particular to a rear wheel brake structure of a baby carriage. The rear wheel brake structure comprises rear wheels, a rear wheel connecting rod and carriage frames. A pedal plate is connected to the middle of the rear wheel connecting rod in a sleeved mode, a locating ring is arranged in the right side of the pedal plate in a sleeved mode, a brake disk is connected to the inner side of the corresponding rear wheel on the right portion in a screwed mode, brake holes are formed in the inner side of the brake disk, the right portion of the rear wheel connecting rod is provided with a locating boss, guide sliding holes are formed in the bottom of the locating boss and the bottom of the locating ring, a brake bar is arranged in the corresponding guide sliding hole, a spring clamping table is arranged on the brake bar, a reset spring is connected to the brake bar between the spring clamping table and the locating boss in a sleeved mode, and braking grooves are formed in the two sides of the pedal plate. The brake bar is made to move towards the two sides by stepping the pedal plate downwards, so that the brake bar is inserted into the corresponding brake hole, therefore, braking of the baby carriage is quickly and effectively achieved, safety is improved and use is convenient.
Description
Technical field
The utility model relates to perambulator technical field, relates in particular to a kind of rear wheel brake structure of perambulator.
Background technology
Perambulator is to have baby's family's outgoing to bring great convenience, also bring a lot of benefits in daily life, according to people's different demand, perambulator is in the market of a great variety, but structure is mostly basic identical, in order better to make perambulator have more in use safety, there is on the market part perambulator with brake gear, can use cumbersome, need staff or pin can not leave the brake gear of perambulator, braking effect, along with period of service increases, also can weaken gradually, can cause potential danger.
Utility model content
The purpose of this utility model is to provide a kind of rear wheel brake structure of perambulator, and its tool is easy to use, simple to operate, the feature of Quick brake.
For achieving the above object, the utility model adopts following technical proposals:
A kind of rear wheel brake structure of perambulator, comprise trailing wheel, trailing wheel connecting rod, vehicle frame, the two ends of described trailing wheel connecting rod are bolted with trailing wheel, the left and right sides of described trailing wheel connecting rod is all bolted with vehicle frame, described trailing wheel connecting rod middle part is socketed with stretcher, described stretcher right side inner sleeve has steady ring, the trailing wheel inner side of described trailing wheel connecting rod right part is bolted with coaxial brake disc, described brake disc inner side offers some spoke holes that circularize, described trailing wheel connecting rod right part is provided with positioning boss, described positioning boss and steady ring bottom all offer slide guide hole, in described slide guide hole, be provided with drag bar, described drag bar is provided with Spring Card platform, on drag bar between described Spring Card platform and positioning boss, be socketed with retracing spring, described stretcher both sides offer breaker slot, described breaker slot is from lower toward becoming circular arc degree to tilt.
Wherein, described stretcher left side is provided with the brake structure symmetrical with stretcher right side.
Wherein, the angle of inclination of described breaker slot is 15～30 °
The utility model beneficial effect: the utility model comprises trailing wheel, trailing wheel connecting rod, vehicle frame, the two ends of described trailing wheel connecting rod are bolted with trailing wheel, the left and right sides of described trailing wheel connecting rod is all bolted with vehicle frame, described trailing wheel connecting rod middle part is socketed with stretcher, described stretcher right side inner sleeve has steady ring, the trailing wheel inner side of described trailing wheel connecting rod right part is bolted with coaxial brake disc, described brake disc inner side offers some spoke holes that circularize, described trailing wheel connecting rod right part is provided with positioning boss, described positioning boss and steady ring bottom all offer slide guide hole, in described slide guide hole, be provided with drag bar, described drag bar is provided with Spring Card platform, on drag bar between described Spring Card platform and positioning boss, be socketed with retracing spring, described stretcher both sides offer breaker slot, described breaker slot is from lower toward becoming circular arc degree to tilt, the utility model is rational in infrastructure, by stretcher is stepped on downwards, make drag bar to two side shiftings, drag bar is inserted in spoke hole, again by stretcher is upwards stepped on, retracing spring forces drag bar to intermediary movements, exit spoke hole, thereby reach fast and effectively the brake to perambulator or remove brake, improve safety, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of trailing wheel 2 brake structures of perambulator, comprise trailing wheel 2, trailing wheel connecting rod 3, vehicle frame 1, the two ends of described trailing wheel connecting rod 3 are bolted with trailing wheel 2, the left and right sides of described trailing wheel connecting rod 3 is all bolted with vehicle frame 1, described trailing wheel connecting rod 3 middle parts are socketed with stretcher 4, described stretcher 4 right side inner sleeves have steady ring 10, trailing wheel 2 inner sides of described trailing wheel connecting rod 3 right parts are bolted with coaxial brake disc 6, described brake disc 6 inner sides offer some spoke holes that circularize 7, described trailing wheel connecting rod 3 right parts are provided with positioning boss 8, described positioning boss 8 all offers slide guide hole 11 with steady ring 10 bottoms, in described slide guide hole 11, be provided with drag bar 9, described drag bar 9 is provided with Spring Card platform 12, on drag bar 9 between described Spring Card platform 12 and positioning boss 8, be socketed with retracing spring, described stretcher 4 both sides offer breaker slot 5, described breaker slot 5 is from lower toward becoming circular arc degree to tilt, by stretcher 4 is stepped on downwards, make drag bar 9 to two side shiftings, drag bar 9 is inserted in spoke hole 7, reach braking effect, again by stretcher 4 is upwards stepped on, retracing spring forces drag bar 9 to intermediary movements, exit spoke hole 7, reach releasing braking effect, described drag bar 9 need be selected the steel that hardness is higher, the materials such as aluminium, in case stressed time distortion.
In the present embodiment, described stretcher 4 left sides are provided with the brake structure symmetrical with stretcher 4 right sides, and in use, the trailing wheel 2 of the left and right sides to perambulator is braked simultaneously, has better braking effect, also can reduce braking force.
In the present embodiment, the angle of inclination of described breaker slot 5 is that the angle of inclination of 15～30 ° of described breaker slots 5 is unsuitable excessive, and required like this braking force can increase, and friction force also can increase, thereby can reduce the lost of life of brake gear, concrete angle is selected according to actual conditions.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
