The utility model provides a multi-functional children's handcart, includes a pair of preceding pole setting pole and a pair of back pole setting pole, is provided with the crossbar of two pairs of handing-over between preceding pole setting pole of homonymy and the back pole setting, and every pair of crossbar includes first connecting rod and the second connecting rod of connecting through the pivot, pivot one end and a connecting rod fixed connection, the other end and another connecting rod sliding fit.

Every to an at least connecting rod of crossing of current shallow is connected through the trace with the pole setting, and the structure is complicated relatively, the utility model discloses saved this connecting rod, but with pivot one end and a connecting rod sliding fit for when two connecting rods are close to, the pivot can slide, realizes folding.

Preferably, the connecting rod is provided with a sliding groove matched with the rotating shaft.

Preferably, the end of the rotating shaft is provided with a sliding sleeve in sliding fit with the connecting rod.

No matter set up spout or sliding sleeve, all be in order to realize the sliding fit of pivot and connecting rod, the effect that its reached is basically no difference, nevertheless sets up the sliding sleeve relatively, sets up the spout structure simpler and easier.

Preferably, a front cross rod is arranged between the two front vertical rods, a rear cross rod is arranged between the two rear vertical rods, the two sides of the frame can be connected through the cross rods to form a frame for holding objects, and a cloth cover is generally arranged in the frame.

Preferably, the bottom of the front upright is provided with a front wheel, and the bottom of the rear upright is provided with a rear wheel.

Preferably, in one pair of the cross bars, the rotating shaft is in sliding fit with the second connecting rod, in the other pair of the cross bars, the rotating shaft is in sliding fit with the first connecting rod, and the two pairs of the cross bars are not symmetrically arranged.

In order to support the cloth cover, a bottom rod is arranged between the bottom intersection points of the two pairs of cross rods on the two sides.

The utility model discloses every pivot to the crossbar is slidable, just can be direct between connecting rod and the pole setting, saves other connecting rods, has simplified frame structure.

Detailed Description

As shown in fig. 1, a multifunctional stroller comprises a frame, wherein the frame is provided with a pair of front vertical rods 1 and a pair of rear vertical rods 2, a front cross rod is arranged between the two front vertical rods 1, a rear cross rod is arranged between the two rear vertical rods 2, the frame of the two sides is connected together by the cross rods to form a cuboid shape, and a cloth cover is lined inside the frame and used for containing articles or allowing an infant to sit and play. The bottom of the front upright stanchion 1 is provided with a front wheel 10, and the bottom of the rear upright stanchion is provided with a rear wheel 20.

The structure of only one side of the cart is shown in fig. 1, and the structure of the other side is the same and therefore omitted. Two pairs of cross rods 3 are arranged between the front upright rod 1 and the rear upright rod 2, one end of each pair of cross rods is hinged with the upright rod, the other end of each pair of cross rods is hinged with the other pair of cross rods, and when the front upright rod and the rear upright rod are close to each other, the cross rods are folded.

Each pair of cross rods 3 is protected to rotatably connect the connecting rod 31 and the connecting rod 32 through a rotating shaft 33, one end of the rotating shaft 33 is fixedly connected with the connecting rod 31, the other end of the rotating shaft 33 is provided with a sliding sleeve 34 in sliding fit with the connecting rod 32, and when the folding machine is folded, the sliding sleeve slides along the connecting rod 32, the connecting rod 31 rotates around the rotating shaft 33 and finally approaches the connecting rod 32, and the folding is completed. Of course, the same function can be achieved by directly providing the link 32 with a slide that engages with the rotary shaft 33 without providing a slide. In this embodiment, the other pair of cross bars also have the same structure, and when folded, the two sliding movements are in opposite directions.

As shown in fig. 3-4, the sliding sleeve is disposed on the connecting rod 31, the rotating shaft 33 is connected with the connecting rod 32, and the sliding sleeve 34 slides upwards along the connecting rod 31 when folded. As shown in fig. 5-6, the structure of the other pair of crossbars is changed, and when folded, the two sliding sleeves slide downwards simultaneously.

In order to improve the supporting strength of the frame, a bottom rod (not shown in the figure) is arranged between the bottom intersection points 30 of the two pairs of cross rods on the two sides, and the bottom rod can support the inner cloth cover and prevent the inner articles from collapsing the cloth cover.
