detailed description

A new type of trolley receiving structure, comprising a front supporting foot 99 and a rear supporting foot 98 connected by the front foot joint 6 and the rear foot joint 11, the lower parts of the front supporting foot 99 and the rear supporting foot 98 are equipped with walking wheels, and the front supporting foot 99 is installed on the inner side of the rear supporting foot 98, a handle push rod 97 is connected between the front foot joint 6 and the rear foot joint 11 through the handle joint 10, and the front foot joint tooth 7 is installed through a spring between the front foot joint 6 and the rear foot joint 11 , the rear joint tooth 9 and the large joint rotating tooth 8, the top of the handle push rod 97 is connected with the hand push elbow 96 through the handle down bend joint 2 and the handle up bend joint 5, and the handle down bend joint 2 and the handle up bend joint 5 A backguy cover 3 and a handle bending joint gear 4 are installed through a spring, and a handle operation button 1 is installed outside the handle down knuckle 2, and a backguy is connected between the backguy cover 3 and the large joint rotating tooth 8.

The inner side of the large joint rotating tooth 8 is provided with a push-off inclined surface 81 corresponding to the rear joint tooth 9 .

The front foot joint 6, the rear foot joint 11 and the handle joint 10 are all provided with limiting notches.

The outer side of the handle push rod 97 is provided with a ring buckle, and the outer side of the rear supporting foot 98 is provided with a buckle ring. After the trolley is closed, the ring buckle is buckled in the buckle ring. As shown in Figure 7, after the whole utility model can be put away, it can be fixed to prevent it from popping open.
