Description

Automatic braking device of baby stroller Technical Field The utility model relates to an automatic braking device of a baby stroller, and belongs to the field of baby stroller tools. Background The baby stroller is a favorite walking vehicle for babies, is a necessary product for the babies to shop on the street, can liberate the hands of the babies, and reduces the labor intensity of the parents carrying the children when going out. Along with the development of science and technology, the functions of the baby stroller are originally stronger and safer, the baby stroller mainly comprises a vehicle body, rollers, a hand push rod, a seat cushion, a awning and the like, in order to ensure safety, a plurality of baby strollers are also provided with braking devices, the braking modes of the baby strollers are pedal type arranged on wheels, the wheels are locked by stepping on the pedals, the braking needs to be locked at any time when the baby stroller is parked, the situation that the baby stroller is forgotten to be locked when the baby stroller is parked often occurs, and accidents are caused by the baby stroller in news. Some high-grade infants push the automatic brake device, but the wheels are provided with brake discs, and the normal lock mechanism is matched with the brake discs to realize the purpose of automatic braking, but the existing automatic brake device is complex in mechanism and high in cost, so that common people house with common income cannot purchase the automatic brake device. Therefore, there is a need for an automatic brake device for a stroller with low cost and simple structure, which can automatically brake when the stroller is out of hand, thereby improving the safety of the stroller. Disclosure of Invention Therefore, the utility model aims to provide an automatic braking device of a baby stroller, which can automatically brake when a user takes off hands, so that the safety is improved; can overcome the defects of the prior art. The utility model aims at realizing the following technical scheme: the utility model discloses an automatic braking device of a baby stroller, which comprises a stroller body, wherein a roller with spokes and a hand-pushing holding rod are arranged on the stroller body, a brake handle is arranged on the hand-pushing holding rod, a brake pull rope is connected to the brake handle, the other end of the brake pull rope is connected with the roller braking device, the roller braking device prevents the roller from rolling through a moving rod inserted between the spokes of the roller, and the moving rod of the roller braking device is always positioned between the spokes of the roller when the brake pull rope is not pulled by the brake handle. The automatic braking device of the baby stroller is characterized in that the roller braking device further comprises a sleeve arranged on the stroller body, annular limiting rings are arranged at two ends of the sleeve, the movable rod is inserted into the sleeve, one end of the movable rod is connected with the braking pull rope, the other end of the movable rod penetrates through the annular limiting rings and then is inserted between spokes of the roller, and an elastic device which enables the movable rod to extend out and be inserted into the spokes of the roller is arranged in the sleeve. The elastic device comprises a limit ring arranged on the movable rod, the limit ring is positioned in the sleeve, and a pressure spring is arranged between the limit ring and the sleeve at the traction end.
