The utility model relates to the technical field of baby products, in particular to a folding and locking device of a baby carriage. The folding and locking device comprises two frame rods, two upper links, a middle link, two lower links, two connecting links, a lock column, a double lock seat and a folding pedal column, wherein the folding pedal column is arranged at a hinge joint of the lower links and the middle link; the lock column is arranged at the hinge joint of the upper links and the middle link; the double lock seat is connected to the middle link in a sliding way; the double lock seat is provided with a lock hole; the lock column is clamped in the lock hole; under the condition that the baby carriage is stretched, the lock column on the upper links and the middle link is clamped by the lock hole of the double lock seat when a first lock fails, and the link mechanism cannot be folded upwards so as not to continuously fold the baby carriage to achieve an effect of double lock; and when the baby carriage is required to be folded, the folding pedal of the first lock is pressed upwards, then the top of the double lock seat is trampled outwards, and the lock column falls off the lock hole of the double lock seat, so that the baby carriage can be folded. And the folding and locking device has the advantages that the safety coefficient is high, the structure is simple and the use is convenient.
Description
Technical field:
The utility model relates to the articles for babies technical field, relates in particular to a kind of perambulator and folds Locking Device.
Background technology:
Perambulator can be placed seat, hand basket or automobile seat on skeleton, be mainly used in to supply the child to take or place article.Existing stroller includes front vehicle frame, back vehicle frame and handle, and the front vehicle frame bottom is equipped with preceding wheels, and back bottom of frame is equipped with the back wheels, and front vehicle frame and handle are hinged with the back vehicle frame respectively, form accordion structure.The vehicle frame of some perambulator also is a folding structure now, and vehicle frame is generally fixed through Locking Device after launching, but this Locking Device has only lock one, and vehicle frame just can arbitrarily fold when this one lock loses efficacy, and caused the injured accident of baby easily, and safety is low.
The utility model content:
The purpose of the utility model is exactly to provide a kind of safe perambulator to fold Locking Device to the deficiency of prior art existence.
To achieve these goals, the technical scheme of the utility model employing is:
Perambulator folds Locking Device; Include two vehicle frame bars, two boxed rods, intermediate connecting rod, two lower links, two connect connecting rod, lock, two road locks, fold the pedal post; First end of two boxed rods is all hinged with the upper end of intermediate connecting rod, and second end of two boxed rods is hinged on respectively on two vehicle frame bars, and first end of two lower links is all hinged with the lower end of intermediate connecting rod; Second end of two lower links is hinged on respectively on two vehicle frame bars; Two upper ends that connect connecting rod are hinged on respectively on the two road locks, and two lower ends that connect connecting rod are hinged with second end of two lower links respectively, fold the hinged place that the pedal post is arranged on lower link and intermediate connecting rod; Lock is arranged on the hinged place of boxed rod and intermediate connecting rod; Two road locks are slidingly connected on the intermediate connecting rod, offer lockhole on the two road locks, and lock is fastened in the lockhole.
The top of said two road locks outwards is bent to form lug.
The material of said two road locks is a plastic cement.
Said boxed rod and lower link laterally arrange.
The utility model beneficial effect is: the utility model include two vehicle frame bars, two boxed rods, intermediate connecting rod, two lower links, two connect connecting rod, lock, two road locks, fold the pedal post; Fold the pedal post and be arranged on the hinged place of lower link and intermediate connecting rod; Lock is arranged on the hinged place of boxed rod and intermediate connecting rod, and two road locks are slidingly connected on the intermediate connecting rod, offers lockhole on the two road locks; Lock is fastened in the lockhole; Under perambulator expansion situation, when first road lock lost efficacy, the lock on boxed rod and the intermediate connecting rod was blocked by the lockhole of two road locks; Thereby connecting rod mechanism can not up fold and can not continue to return the vehicle to the garage and knock off, and plays the effect of two roads lock; In the time of need returning the vehicle to the garage and knock off, the pedal post that folds with first road lock up pushes up earlier, steps on lock top, two roads more outward, and lock just comes off out from the lockhole of two road locks, and just can return the vehicle to the garage and knock off this moment, and safety factor is high, and is simple in structure, easy to use.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the decomposing schematic representation of the utility model.
Fig. 3 is the structural representation that the utility model is opened first road lock.
Fig. 4 is the structural representation that the utility model is opened second road lock.
