Abstract
The utility model relates to a mechanism capable of realizing dual-braking on rear wheels through one tread for an umbrella-shaped baby carrier. The mechanism comprises two groups of rear wheels and two rear wheel seats; the mechanism is characterized in that gear grooves are formed in wheel axles of the left driving rear wheel and the right driving rear wheel of the umbrella-shaped baby carrier, a braking nail is arranged beside each of the left gear groove and the right gear groove, a braking steel wire rope is connected between the two braking nails, return springs are connected between the left and right rear wheel braking nails and the braking steel wire, and a braking rod is connected to the right braking nail; when the braking rod is trod, the left and right braking nails connected together with the braking rod are moved together through the driving of the braking rod, and then clamped in the gear grooves of the left and right rear driving wheels, so that the braking of the left and right rear wheel sets of the whole baby carrier can be realized; when the braking rod is hooked by an instep, under the effects of the return springs and the braking steel wire rope, the left and right braking nails are promptly slide out of the clamped gear grooves, so that the unlocking of the rear wheel sets can be realized. According to the mechanism provided by the utility model, the braking rod is only arranged on the rear wheel on one side, all that is needed is to tread or hook the braking rod, the functions of braking and the unlocking of the rear wheel sets can be realized, and the convenience is increased and the safety of the baby carrier is improved during moving.
Description
Technical field
The utility model relates to a kind of brake structure of perambulator, is that a kind of rear foot one for umbellate form perambulator is stepped on double brake mechanism specifically.
Background technology
As everyone knows, perambulator needs well steadily and safety in traveling process, and therefore whether the braking mechanism of perambulator is convenient, sensitive and be reliably the leading indicator of perambulator quality.The braking mechanism of perambulator is generally to adopt left and right trailing wheel to separate the mode of braking and release at present, braking and release need operate respectively the right and left trailing wheel could realize a function of stepping on dual brake, and this structure makes to kill car troublesome poeration, blunt, not too reliable, person even falls car accident.Vast Parents urgently wishes a kind of convenient, sensitive, and the reliable and good perambulator of safety appears on the market, and in order to eliminate user's trouble and worry, guarantees children's health and safety.
Summary of the invention
For overcoming the above-mentioned defect of existing perambulator brake structure, the purpose of this utility model is to provide a kind of rear foot one for umbellate form perambulator and steps on double brake mechanism, in order to strengthen sensitieness and the reliability of brake mechanism of baby carriage, improves the convenient sense and the degree of safety that use perambulator.
For solving its technical matters, the technical solution adopted in the utility model is: the rear foot one for umbellate form perambulator of designing is stepped on double brake mechanism, comprise two groups of trailing wheels and two rear wheel seats, its feature is: on the wheel shaft of two the active trailing wheels in the left and right of this umbellate form perambulator, be equipped with gear grooved, in left and right, two gear grooved sides are respectively provided with a brake nail, between two brake nails, be connected with brake steel wire, between left and right rear wheel brake nail and brake steel wire, be connected with retracing spring, nail on and be connected with brake lever in right brake, this brake lever is the driving link of braking and the release of braking mechanism, stepping on brake lever will drive the right brake nail connecting together with it to move together, make right brake nail inlay card in the gear grooved of right back driving wheel, block this and take turns rotation, simultaneously, the left brake nail that the other end of brake steel wire is connected also can snap in the gear grooved of left rear wheel, blocking left active trailing wheel rotates, realize the braking of the rear wheels in car load left and right, when release, trigger brake lever with instep, under the effect of retracing spring and brake steel wire rope, left and right brake nail skids off the gear grooved engaging at once, the release of wheels after realizing.
Compared with prior art, the utility model has following features and progress: because this perambulator is provided with two trailing wheels in left and right, each trailing wheel is provided with again a driving wheel and an auxiliary wheel, be fixed on two rear wheel seats in left and right by an axle, on inner side wheel shaft due to each driving wheel, be equipped with gear grooved, on the rear wheel seat on two gear grooveds sides, be respectively equipped with a left side, right brake nail, one end of two brake nails is facilitated with the two ends of steel rope and is connected by retracing spring, the lower end of right brake nail is connected to an one end that adopts the brake lever of lever construction, the fulcrum of its lever is arranged on adjacent rear wheel seat, the other end of lever is force side, the touch on the brake force side of bar of pin can make brake nail up-and-down movement.In the time tramping with one's feet this brake lever, two brake nail inlay cards initiatively in the gear grooved of trailing wheels, are realized brake function at two, and in the time lifting out brake lever with pin, two brake nails are under the effect of retracing spring, and the gear grooved that speeds away, realizes the object of release.Therefore this perambulator need only be stepped on monolateral braking and the unlocking function that just can realize both sides wheels, convenient sense and degree of safety while being conducive to improve perambulator walking.
