Detailed Description

As shown in fig. 1-3, a foldable stroller for children comprises a frame 1, wherein the frame 1 comprises a front wheel 13 frame 2 and a rear wheel 15 frame 3 which are movably assembled in a crossing manner. The front wheel 13 frame 2 is provided with a connecting seat 4 and a pivot 5 movably assembled on the connecting seat 4, the pivot 5 is inserted on the connecting seat 4, and the pivot 5 and the connecting seat 4 can be fixedly connected or movably assembled, which depends on actual production. The pivot 5 acts like a cross-over point, and when the position of the pivot 5 is restricted, the other parts are relatively stable in overall structure no matter how they swing. The rear wheel 15 frame 3 is provided with a fixed seat 7 and a clamping seat 6 in elastic connection, the fixed seat 7 is provided with a through groove for mounting the clamping seat 6, one end of the through groove close to the pivot 5 is a clamping opening, the end of the through groove opposite to the pivot 5 is a pulling opening, the clamping seat 6 has a tendency of moving from the pulling opening to the clamping opening, and the clamping seat 6 is provided with a limiting blocking plate 8 at the pulling opening. The clamping seat 6 moves back and forth in the fixed seat 7, which can be elastically connected by a spring or other elastic member, and then the moving distance is limited by the blocking plate 8, which is only one of the embodiments thereof, but not the only limitation thereof.

The rear wheel 15 frame 3 is also provided with a supporting seat 9, the supporting seat 9 is provided with a buckling station 10 for buckling the pivot 5, an unfolding state and a folding state are arranged between the front wheel 13 frame 2 and the rear wheel 15 frame 3, the clamping seat 6 extends out of the clamping opening in the unfolding state, and the pivot 5 is limited and fixed with the clamping seat 6 through the buckling station 10; when the folding state is carried out, the clamping seat 6 moves towards the drawing opening by pulling the blocking plate 8, and the front wheel 13 frame 2 drives the pivot 5 to be separated from the buckling station 10 by rotating. The closed ring locking pivot 5 is formed by matching the supporting seat 9, namely the buckling seat 10, with the clamping seat 6, so that the fixing and limiting effects are achieved.

The seat is hinged to the front wheel 13 frame 2 and the rear wheel 15 frame 3 respectively. When a child sits on the chair, gravity presses downwards to stabilize the connection structure of the front wheel 13 frame 2 and the rear wheel 15 frame 3, and the chair is relatively stable and has low freedom. The supporting seat 9 and the fixed seat 7 are connected to form an integrated structure. The production is convenient, the structural strength can be improved, and the assembly procedures are reduced.

The front wheel 13 frame 2 comprises a single rod 11, the rear wheel 15 frame 3 comprises two outer rods 12, and the single rod 11 is arranged between the two outer rods 12. This is one of the embodiments, and the two outer rods 12 are more stable in structure corresponding to the relative force applied to the human body relatively backward and backward in an emergency.

The buckling table 10 is provided with a fan-shaped buckling groove, the buckling groove penetrates through the buckling table 10, and the angle of the center of the fan-shaped section of the buckling groove is larger than or equal to 180 degrees. Reach better fixed spacing effect, play the lock joint effect when central angle degree is bigger a bit.

The front wheel 13 frame 2 further comprises a pedal 14 connected with the single rod 11, and front wheels 13 are respectively arranged at two ends below the pedal 14. The downward end of the outer rod 12 is provided with a rear wheel 15, and a connecting rod 16 is arranged between the rear wheels 15 of different outer rods 12. The four-wheel rolling type rolling machine is equivalent to four-wheel rolling, the stability is high, and meanwhile, the connecting rods 16 are matched to further strengthen the structural stability and improve the local structural strength.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing and simplifying the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, are not to be considered as limiting the present invention, and that the fundamental principles, the main features, and the advantages of the present invention are shown and described above, as would be understood by those skilled in the art.
