Abstract
The utility model relates to a baby carriage, in particular to a folded joint connecting mechanism of the baby carriage. The folded joint connecting mechanism comprises a first connecting rod, a second connecting rod, a joint sleeve and a joint seat, wherein the upper end of the first connecting rod is fixedly connected with the joint sleeve; the lower end of the second connecting rod is fixedly connected with the joint seat; the joint sleeve is rotationally connected with the joint seat through a pivot hole; and the first and the second arc surfaces for the joint sleeve in a joint sleeve groove as well as the first and the second arc surfaces of the joint seat are all rotationally connected in the form of concentric arcs by taking the pivot hole as a rotary central shaft. A gap in the process of folding the baby carriage is eliminated so as to prevent hands from being clipped in operation, so that the folded joint connecting mechanism is higher in safety, simple in structure and lower in cost.
Description
Technical field
The utility model relates to doll carriage, is specifically related to a kind of folding joint bindiny mechanism of doll carriage.
Background technology
The baby stroller in existing market adopts folding structure mostly, so that carry aspect in trip process by bus, and do not take too many space.Existing baby stroller is generally head rod and is connected with second by a joint sleeve connection, connect front wheels under the head rod, joint handgrip group on the second pipe link, the pivot hole in the joint sleeve is as pivot point, the second pipe link rotates round head rod, thereby plays the effect that folds.Because it is can shape at a certain angle that the joint set in existing market greatly mainly with the open type joint set, wherein folds in the process joint sleeve and the second pipe link, in the process of launching fully, crush easily child's hand.
For this problem, the folding joint of doll carriage adopts two to connect the pivot point joint more at present, and two circular joints of adopting a pivot point are also arranged, and it is closely connected and can avoids clipping to finger.Yet the external force that folding joint is subject in the situation of carrying out is very large, in the little situation of area of contact easily so that folding joint outwards cast aside and cause damage, area increased or the inside to strengthen too cost of idleness with iron plate, and complex structure.
The utility model content
Technical problem to be solved in the utility model provide a kind of low cost and launch with the process that folds in can not cause the unstable of vehicle frame, and can guarantee the folding joint bindiny mechanism of doll carriage of user and child's safety.
The utility model solves the problems of the technologies described above as follows: the folding joint bindiny mechanism of a kind of doll carriage described in the utility model comprises head rod, the second pipe link, joint sleeve and socket joint; Captive joint with joint sleeve in the head rod upper end, the lower end is connected with the baby-carrier fore wheel group; Captive joint with socket joint in the second pipe link lower end, the upper end connects handrail; Joint sleeve and socket joint are rotationally connected by the pivot hole of off-centre, and take the pivot hole as rotary middle spindle, socket joint is connected in the groove of joint sleeve; Joint sleeve is provided with indent slot type joint sleeve the first cambered surface and joint sleeve the second cambered surface; Socket joint is provided with socket joint the first cambered surface and socket joint second cambered surface of evagination; Joint sleeve the first cambered surface and joint sleeve the second cambered surface and socket joint the first cambered surface and socket joint the second cambered surface are all the concentric cambered surface centered by the pivot hole; Arc drop face by socket joint between socket joint the first cambered surface and socket joint the second cambered surface connects; Arc drop face by joint sleeve between joint sleeve the first cambered surface and joint sleeve the second cambered surface connects.
Head rod and second connecting rod rely on joint sleeve to be connected the connection of " one " font straight line with socket joint and launch, and the arc drop face clamping of the arc drop face of socket joint and joint sleeve is so that joint sleeve and socket joint are got spacing effect in the process of mutually rotating; The combination of joint sleeve and socket joint is long semiellipse state, so that the longitudinally strength of joint sleeve and socket joint is greater than horizontal direction strength, its structure can so that vehicle frame is outwards cast aside, not guarantee beautifying of outward appearance simultaneously.
Good effect of the present utility model: the folding joint bindiny mechanism of a kind of doll carriage described in the utility model low-cost and launch with the process that folds in can not cause the unstable of vehicle frame, in the hand barrow folding process, eliminated gap wherein, when avoiding operating by hand folding, guarantee user and child's safety, this folding joint bindiny mechanism installs, convenient disassembly, simple to operate, also have simple for structure, the characteristics such as fashion is attractive in appearance.

The specific embodiment
As shown in Figures 1 to 4, the folding joint bindiny mechanism of a kind of doll carriage described in the utility model comprises head rod (4), the second pipe link (1), joint sleeve (3) and socket joint (2); Captive joint with joint sleeve (3) in head rod (4) upper end, the lower end is connected with the baby-carrier fore wheel group; Captive joint with socket joint (2) in the second pipe link (1) lower end, the upper end connects handrail; Joint sleeve (3) is rotationally connected by eccentric pivot hole (5) with socket joint (2), and take pivot hole (5) as rotary middle spindle, socket joint (2) is connected in the groove of joint sleeve (3); Joint sleeve (3) is provided with indent slot type joint sleeve the first cambered surface (3-1) and joint sleeve the second cambered surface (3-2); Socket joint (2) is provided with socket joint the first cambered surface (2-1) and socket joint second cambered surface (2-2) of evagination; Joint sleeve the first cambered surface (3-1) and joint sleeve the second cambered surface (3-2) and socket joint the first cambered surface (2-1) and socket joint the second cambered surface (2-2) are all the concentric cambered surface centered by pivot hole (5); Arc drop face (2-3) by socket joint between socket joint the first cambered surface (2-1) and socket joint the second cambered surface (2-2) connects; Arc drop face (3-3) by joint sleeve between joint sleeve the first cambered surface (3-1) and joint sleeve the second cambered surface (3-2) connects.
In the process of returning the vehicle to the garage and knock off, the second pipe link (1) socket joint (2) rotatablely moves around pivot hole (5), so that the arc drop face (3-3) of joint sleeve separates with the arc drop face (2-3) of socket joint; Socket joint the first cambered surface (2-1) enters joint sleeve the second cambered surface (3-2) in the process of launching, socket joint the second cambered surface (2-2) enters joint sleeve the first cambered surface (3-1), cooperate the gap of having eliminated tong between cambered surface and cambered surface, when the arc drop face (2-3) of the arc drop face (3-3) of joint sleeve and socket joint when being close together, socket joint (2) can not continue to rotatablely move with joint sleeve (3), head rod (4) and second connecting rod (1) rely on joint sleeve (3) to be connected 2 with socket joint) be " one " font straight line connection expansion, this moment, vehicle frame was in the state that launches fully.
