Abstract

The invention discloses a non-shaking adjusting joint for a baby carriage and relates to a joint structure which is used for adjusting or locking the baby carriage. The non-shaking adjusting joint for the baby carriage mainly comprises an inner joint, an outer joint, a gear, a bushing, an elastic element, a key and the like, wherein a gear ring which is matched with the gear is arranged on the outer joint. The non-shaking adjusting joint for the baby carriage is technically characterized in that the gear teeth of the gear are designed into the shape of conical blocks with larger inner ends and smaller outer ends, the gear-ring slot of the gear ring is designed into the shape of a conical slot with a larger inner end and a smaller outer end, and therefore the non-clearance fit between the gear teeth and the ear-ring slot in a locking state is realized through the axial movable assembly between the gear and the gear ring. The characteristic of the non-clearance fit between the conical blocks and the conical slot is mainly utilized by the improved adjusting joint, so that no radial shaking of the adjusting joint can be generated in the locking state, and therefore the stability and the reliability in use are always guaranteed.

Description

Perambulator is without rocking adjusting joint
Technical field
The present invention relates to a kind of bent adjusting joint for perambulator, specifically refer to that perambulator is without rocking adjusting joint.
Background technology
As everyone knows, on perambulator, conventionally need to possess a lot of articulation structures, conventional as on handle joint, the folding/unfolding joint of ride and the joints such as adjustment of child pedal position and handrail for children of design in car push handle, can be respectively used to regulate the upper and lower use height of handle, the opening and fold, foot-operated height and the angular adjustment of handrail etc. of ride.At present, most adjusting joint all can be applied to shift structure to realize the rotation of all angles and regulate or sealed, this shift structure is mainly to be realized by the axial active mounting between gear and gear ring, " bracket column head structure " that the structure adopting and disclosed China Patent No. are 201020258026.3 is similar, with time cooperation by button and elastic element realize moving axially of gear, and by moving axially of gear, be equipped with gear ring or depart from, thereby realized the adjusting in joint or sealed.In above-mentioned adjustment structure, gear and gear ring to move axially equipped be mainly to realize by the gear ring groove on the gear teeth on top circle side face and gear ring inner peripheral surface, the gear teeth are pushed in gear ring groove, joint regulates by sealed, the gear teeth are pushed in separating tooth ring recess, adjusting can be rotated in joint, the gear teeth in this fit structure and gear ring groove have adopted the structure of straight-tooth and straight trough mostly, although the abarticular operation of this equipped structure or sealed, but in actual use, owing to needing axial activity between gear and gear ring, institute is so that certainly exist gap between the gear teeth and gear ring groove, otherwise gear cannot be pushed open by user and gear and teeth groove be departed from, elastic element also cannot make reset gear and make the gear teeth and gear ring groove sealed, its consequence of bringing is exactly that more radially rocking appears in adjusting joint in use, the steadiness and the reliability that use have been affected.
Summary of the invention
Technical matters to be solved by this invention is to overcome the defect of prior art and provides a kind of locked state can not produce to rock, and uses firm, failure-free perambulator without rocking adjusting joint.
Technical matters of the present invention is achieved through the following technical solutions:
