Description
Technical field
The present invention relates to perambulator technical field more particularly to a kind of infant car seat pockets.
Background technique
Have currently on the market most of perambulator of detachable independent seat pocket it is equivalent after bulky dimensions, be unfavorable for storage and
It carries, traces it to its cause in the assembly chassis assembly for the present pocket two sides of disassembly mechanism design for being primarily due to a pocket, because mechanism is set
The assembling assembly that meter and handgrip position need space to lead to two sides is oversized, on the one hand influences the compactedness of appearance, another party
Face keeps backrest equivalent without normal direction seat board direction, even if can convert into completely, but seat pocket disassembly mechanism can accomplish the lower section of seat board, make
User is not easily found a pocket disassembly mechanism, and assembling stand pocket is when on vehicle frame, because the both hands of operation are apart from assembling assembly position
It is too far, and be not easy to make the assembly box of assembling assembly alignment vehicle frame, while operation dismounting mechanism, need to mention a pocket, because
Operating position deviates seat pocket center of gravity and causes operating difficulties.Seat pocket disassembly mechanism is not accomplished backrest two by babychair pocket at present
Side because backrest usually require to adjust angle and also to realize it is equivalent with seat board, between relative displacement it is very big, it is difficult to
Realize that seat pocket disassembly mechanism is arranged in backrest two sides.
Summary of the invention
The technical problem to be solved in the present invention is that in view of the deficiencies of the prior art, providing a kind of infant car seat pocket.
In order to solve the above technical problems, the present invention adopts the following technical scheme that.
