As can be seen from fig. 1, the frame of the stroller of the present utility model has a plurality of similarly configured fixed joints disposed at the corners of the seat fabric of each stroller, respectively. As described above, the linking device 3 can be sleeved on the fixed joint. Thus, a plurality of linking means 3 may be used to fasten the fixed joints in pairs, thereby enabling a plurality of child dollies to be grouped together.

Taking two strollers as an example, the steps of combining the stroller using the linking device 3 are as follows:

the first and second connection portions 301, 302 are slip-fit in place and placed against the lower surfaces of the first and second seat cloths 102, 202, respectively;

-passing two screws 305 downwards from above the seat cloth through the first connection 301 and the second connection 302, respectively;

sleeving the first connecting portion 301 and the second connecting portion 302 onto the first fixing tab 103 and the second fixing tab 203 from top to bottom until the frame connecting ends 105, 205 from which the two fixing tabs 103 and 203 extend abut against the arc-shaped shroud portions 307 of the two connecting portions;

two nuts 306 are screwed onto the ends of the screw 305, respectively, until they abut against the bottom end of the fixed joint.

If a plurality of child carts are required to be combined, repeating the steps.

When it is desired to disengage the child dollies from each other, without dismantling the linking device 3, the first connection 301 and/or the second connection 302 are moved in the direction in which the slot 303 extends, so that the two are moved relative to each other until disengaged.

In the use of the combined type child cart, as the child cart has rigidity, each child cart in the combined type child cart moves in the vertical direction (namely, the extending direction of the slot 303) to a small extent, so that the condition that the two connecting parts of the link device 3 slip off to separate the child carts from each other is avoided; the two connecting parts are mutually meshed along the lateral direction (perpendicular to the extending direction of the slot 303), and the two connecting parts are tightly matched, so that the two connecting parts cannot be separated along the lateral direction, and the situation that the child trolley is separated from each other is avoided.

The utility model uses the sliding-plug matched linking device, so that the baby carriage can be combined and separated under the condition of not arranging an additional locking device and an unlocking device, and the problem of inconvenient use caused by complex connector structure in the prior art is solved; in addition, the linking device has a small and simple structure, and can be firmly fixed on the fastening joint of the baby stroller, so that a plurality of the baby strollers can be combined by using a plurality of the linking devices, the problem that the combined number of the baby strollers is limited due to the large size of the connector in the prior art or the problem that the linking device is difficult to detach and replace is solved, and the application scene is expanded.
