A kind of dibit infant seat for automobiles vehicle frame
Technical field
The present invention relates to a kind of dibit infant seat for automobiles vehicle frame.
Background technology
Infant seat for automobiles takes advantage of an automobile to bring safety to the baby, and some regional traffic law is regulation specially also, and the baby/child of given age must use infant seat for automobiles when taking advantage of automobile.
In order not wake the baby in sleeping soundly up, also for ease, when getting off, people get used to the baby is shifted together with infant seat for automobiles in the lump.But infant seat for automobiles is generally relatively heavier, carries for a long time or shoulders even if the male sex is grown up, and is all tired unavoidably.If twins are two babies, lift two vapour chairs more is not a nothing the matter.
The someone had invented the double-seat baby-car vehicle frame afterwards, can be placed in the trunk of automobile, was used for loading infant seat for automobiles specially.Like Chinese patent document CN201095380Y in the disclosed stroller that is used to install infant car seat on August 6th, 2008; Comprise collection agency; Also comprise two cover infant car seat erecting devices, two cover infant car seat erecting devices one in front and one in back vertically are provided with.Vehicle frame comprises two parallel back timbers of establishing, and back timber is two horizontally disposed pipe fittings, lay respectively at vehicle frame about two sides, described two cover infant car seat erecting devices are arranged on two back timbers; Described two back timbers are the compound type pipe fitting, and every back timber is detachably combined through Connection Block by two pipe fittings; The last period of back timber, removable pipe fitting was the back timber leading portion, and back one section of back timber is the back timber back segment; The first cover infant car seat erecting device is arranged at the back timber leading portion, and second section safety chair seats of car is arranged at the back timber back segment; Every cover infant car seat comprises a clamp, cross bar and a pair of safety strap that can snapping; Clamp is preceding, and safety strap is arranged between clamp and the cross bar; The clamp of the first cover infant car seat erecting device is arranged on the back timber leading portion foremost; Two ends are sheathed on two back timbers about said clamp, and through the fastener locking; Said cross bar is vertical with back timber to be provided with, and sealed through fastener and back timber; Said back timber is to connect through spiral nail with being connected of cross bar, and the back timber leading portion is tightened up a screw the nail hole more than a pair of, staggers before and after each spiral nail hole also more than a pair of in the spiral nail hole of back timber back segment; Said baby's vehicle frame also comprises " U " type handrail of being inverted, two sides sheathed two blocks respectively about the handrail lower end; The vertical setting of said clamp, the clamp top has fillet, so that infant car seat snaps in; Clamp has the sealed button bit of the infant car seat button hook of confession, and said button bit has one at least, is arranged on the middle part of clamp left and right directions at least.
Though stroller of the prior art can be installed two infant car seats simultaneously, it is bulky, and especially the vehicle frame longitudinal separation is longer, and inconvenience is carried.And because longitudinal separation is longer, the front and back hack lever is prone to produce distortion, and service life is short.
Summary of the invention
The objective of the invention is to overcome the weak point of above-mentioned prior art and provide a kind of volume little dibit infant seat for automobiles vehicle frame.
