Publication number is that the Chinese patent literature of CN201347112 discloses a kind of foldable baby carriage vehicle frame, and seatpost that head rod that push rod that the after-poppet being rotationally connected with fore-stock including fore-stock is slidably connected with fore-stock, both ends are rotationally connected with fore-stock and push rod respectively, one end are rotationally connected with push rod, one end are rotationally connected with push rod and the other end is at least one folding latch hook of hook solid, the lock pin coordinated with folding latch hook that is arranged on fore-stock。After folding knob unlocks and fold latch hook unblock, promoting push rod to glide, by, under connecting rod effect, there is planar movement in its front end, by seatpost, pull after-poppet push rod forward close, complete folding process, when needs support perambulator, reverse operating above procedure, can complete。
Technique scheme achieves the folding of perambulator, but folding process is relatively cumbersome, and child is easily damaged by the articulation mechanism of multiple exposures simultaneously。
Publication number is that the Chinese patent literature of CN201257998 discloses a kind of folding joint for storing foldable baby carriage and relates to foldable stroller, including front-wheel support, driver's support, function pull handle and function latch, front-wheel support end is fixing connects lower seat, driver's support front end is fixing connects the seat of honour, connect lower seat and be connected the seat of honour and be rotationally connected, it is installed with bracing wire in driver's support, there is in front-wheel support and the connection seat of honour accommodating hole of accommodating function latch, function pull handle is connected with function latch by bracing wire, function latch is provided with spring, function latch is at function pull handle, the accommodating hole of front-wheel support can be partially under spring and bracing wire effect, part coordinates with the accommodating hole being connected the seat of honour, or depart from the accommodating hole of front-wheel support, all coordinate with the accommodating hole being connected the seat of honour。This technical scheme optimizes the position of the switch by bracing wire, improves safety, but folding process is still relatively cumbersome。
Utility model content
For the deficiency that prior art exists, this utility model provides a kind of folding convenient, the baby carriage that the linkage of simple in construction folds。
The technical solution of the utility model is:
A kind of folding baby carriage that links, including front foot lever, rear foot lever and pushing hands bar, the top of described front foot lever and rear foot lever is swung by linkage and connects, it is connected to front support rod and back support rod between described front foot lever and pushing hands bar and constitutes folding first quadric chain, by being connected with first connecting rod and second connecting rod in turn and constituting the second quadric chain between described front foot lever and rear foot lever, fixing connection between described front support rod and first connecting rod；First quadric chain of folded state and rear foot lever are stacked in the upper and lower both sides of front foot lever respectively。
In order to reach the effect of linkage, baby carriage is by driving foot lever after the second quadric chain folding by fixing connection between front support rod and first connecting rod while the first double leval jib machine folding, as long as thus reaching an action and just can link the purpose of the whole baby carriage of folding。Meanwhile, when car load all folds and puts in place, the folding respectively of the first quadric chain and rear foot lever is in front foot lever both sides。
As preferably, described linkage includes the first pivot and the second pivot that are arranged in parallel, the middle part of described pushing hands bar is hinged on this first pivot by back support rod, it is provided with the 3rd pivot in the middle part of described front foot lever, the bottom of described pushing hands bar is hinged on the 3rd pivot by front support rod, and the top of described rear foot lever is hinged on the second pivot。
In order to optimize folding action, linkage is arranged side by side the first pivot and the second pivot, and the middle part of pushing hands bar is hinged on the top of back support rod, and the bottom-hinged of back support rod is on the first pivot；The bottom-hinged of pushing hands bar is at the top of front support rod, and the bottom-hinged of front support rod is on the 3rd pivot；The getting well of the program be in decrease interfere while optimize the arm of force of quadric chain, it is possible to linkage folding baby carriage more easily。
As preferably, described first connecting rod is hinged by described 3rd pivot and front foot lever。
In order to promote quadric chain to work more smoothly, first connecting rod is hinged by described 3rd pivot and front foot lever。Now, the middle part of first connecting rod, front support rod and front foot lever is coaxial。
As preferably, the middle part of described rear foot lever is provided with the 4th pivot, and described second connecting rod is hinged by the 4th pivot and rear foot lever。
In order to optimize the action of foot lever after folding in linkage process, second connecting rod is hinged on the middle part of rear foot lever by the 4th pivot and rear foot lever, it is possible to after guarantee, foot lever folding allows folding action more natural while putting in place。
As preferably, described front support rod and first connecting rod are the integrative-structure of L-shaped, its corner and described 3rd pivot knuckles。
For the effect of strengthening linkage, front support rod and first connecting rod are the integrative-structure of L-shaped。Integrative-structure can save the fixture between front support rod and first connecting rod, thus optimizing structure, reduces cost and weight, and overall structure is also more durable。
As preferably, described linkage also includes the vertical supporting rod being fixed on forward foot in a step masthead portion, and this vertical supporting rod constitutes T-shaped structure with front foot lever, and described first pivot and the second pivot lay respectively at the two ends of vertical supporting rod。
For better layout the first pivot and the second pivot, in forward foot in a step masthead portion, vertical supporting rod is set, first pivot and the second pivot lay respectively at the two ends of vertical supporting rod, just can adjust the distance between the first pivot and the second pivot thus adjusting quadric chain by adjusting vertical supporting rod。
This utility model has the advantage that
(1) design that double-four link mechanism links mutually, folding convenient；
(2) integrated design is integrated, simple in construction, improve the stability of product while reducing parts and cost；
(3) design of vertical supporting rod, regulates quadric chain more convenient。
