Single hand brake device of stroller

Abstract

A single hand brake device of a stroller includes a brake arranged between back wheels at two sides, and a hand controller fixed on a pushing handle tube, wherein the brake and the hand controller areconnected through a metallic pulling rope; when a single hand rotates a wrench, the pulling rope retracts upward, an outer end of a metallic rod of the brake is inserted into an inner hole of the corresponding back wheel to achieve braking; when a finger presses a button of the hand controller, the pulling rope is loosed, the outer end of the metallic rod evacuates from the inner hole of the backwheel, and the braking state is unlocked; and for a stroller having a forward foldable pushing handle tube, quick braking and instant unlocking can be achieved whether a pushing person is in the backor the front of the stroller. The brake device can fully meet the linkage braking demand, and can satisfy the compulsive demand of a brake safety relevant standard of the baby stroller.

Description

technical field [0001] The invention relates to a vehicle for infants, in particular to a one-hand braking device for a stroller. Background technique [0002] In baby strollers, the brakes are generally braked through the pedal linkage of the rear wheels on both sides, which is simple, safe and reliable to use. One of the more excellent brake structures is: build a connecting piece (injection molded part), and at the same time realize the fixed connection with the rear wheel of the car on this side, the lower end of the rear leg tube and one end of the main pipe of the brake between the rear wheels on both sides, The whole brake is left-right symmetrical. The inside of the rear wheel is provided with dense holes surrounding the wheel shaft. The brake pedal limited by the left and right sleeves is centered and can rotate around the main pipe. The left and right brake levers are always limited to be parallel to the main pipe (that is, always parallel to the wheel axis ), the...

Problems solved by technology

People take infants and young children out with the help of strollers, or take a walk for leisure, or go shopping, or travel, and the infants and young children in the stroller are either lying down, half lying, or sitting and standing; the pusher (guardian) is generally located in the The back of the baby, but the handlebar of the stroller can be folded forward to continue pushing the cart, that is, the pusher may also be located in front of the baby, and communicate with the baby while the stroller is moving. It is impossible to step on the brakes directly with your feet. When emergency braking is particularly needed, there is a certain degree of safety risk, although this may be a small probability event
