Detailed Description
As shown in fig. 1 to 6, the present invention provides a multi-function cart, comprising: the device comprises a square main frame 1, two side frames 2, a front wheel frame 3, a bottom frame 4 and a seat pocket 5; the seat bag 5 is detachably arranged on the square main frame 1, the side frames 2 are respectively arranged on two sides of the square main frame 1, the side frames 2 are rotatably arranged on the square main frame 1, the lower end parts of the side frames 2 are provided with rear wheels 6, the rear end part of the bottom frame 4 is arranged between the two side frames 2, and two side parts of the bottom frame 4 are provided with foldable frame fences 41; the front wheel frame 3 is detachably arranged at the bottom of the square main frame 1, the two ends of the front wheel frame 3 are respectively provided with universal wheels 7, and the front end of the bottom frame 4 is detachably arranged on the front wheel frame 3.
Specifically, in actual use, as shown in fig. 1, in the stroller mode, the seat pocket 5 is installed on the square main frame 1, and an infant can sit or lie in the seat pocket 5, and a parent can hold the top of the square main frame 1 and push the multi-function stroller to walk.
When the multifunctional cart is not used for pushing infants, the multifunctional cart can be used as a shopping cart or a hand buggy.
As shown in fig. 2, in the shopping cart mode, the seat bag 5 is detached from the square main frame 1, and at the same time, the frame rails 41 on both sides of the bottom frame 4 are unfolded to the erected state, so that a basket structure is formed between the bottom frame 4 and the frame rails 41. When the multifunctional shopping cart is used, a user can push the multifunctional shopping cart by hands so as to place purchased articles and the like on the bottom frame 4 conveniently, and further the function of the shopping cart is realized.
As shown in fig. 3, in the trolley mode, the seat pocket 5 is detached from the square main frame 1, and the front wheel frame 3 is detached from the square main frame 1 at the same time, and at the same time, the frame rails 41 on both sides of the bottom frame 4 are unfolded to the vertical state, so that a basket structure is formed between the bottom frame 4 and the frame rails 41. When the handcart is used, a user can pull the multifunctional handcart to walk, so that purchased articles and the like can be placed on the bottom frame 4 conveniently, and the function of the handcart is further realized.
Furthermore, in order to position the vertical frame rail 41, the bottom frame 4 is also provided with a detachable movable transverse frame 42; when the frame rails 41 are turned to the standing state, the movable horizontal frame 42 is disposed between the two frame rails 41. Specifically, the movable horizontal frame 42 is sandwiched between the two frames 41 to position the frames 41, and meanwhile, the movable horizontal frame 42 can also serve as a rear stop portion of the storage basket to reduce the articles from being lost.
The front wheel frame 3 and the bottom frame 4 can be detached in a hook-and-loop lap joint manner, that is, the front wheel frame 3 is provided with a first fixing ring 31, the front end of the bottom frame 4 is provided with a first hook 43, and the first hook 43 is hung in the first fixing ring 31. Specifically, when the bottom frame 4 and the front wheel frame 3 need to be connected together, the first hook 43 may be hung in the first fixing ring 31 to connect the bottom frame 4 and the front wheel frame 3. The first fixing rings 31 may be disposed at both ends of the front wheel frame 3, and the two first hooks 43 may be disposed on the bottom frame 4 to be engaged with the first fixing rings.
In addition, as for the detachable manner between the seat pocket 5 and the square main frame 1, the connection may be realized by a conventional manner such as disposing a self-adhesive tape or a snap on the seat pocket 5. For the detachable mode between the front wheel frame 3 and the square main frame 1, an insertion mode can be adopted, for example: fastening the bolt, and the like. The specific disassembling and connecting manner is not limited in structure and is not described in detail herein.
Furthermore, the front end of the bottom frame 4 is further provided with a rotatable connecting rod 44, the free end of the connecting rod 44 is provided with a second hook (not marked), and the front wheel frame 3 is provided with a second fixing ring 32; when the multi-function cart is in the rocking cart mode, the first hooks 43 are disengaged from the first fixing ring 31, and the second hooks are hung in the second fixing ring 32.
Specifically, along with the growth of the infant, in order to fully use the multifunctional stroller, the multifunctional stroller additionally has a child swing mode, at this time, the front wheel frame 3 can also rotate relative to the square main frame 1, the movable transverse frame 42 serves as a backrest, and the seat pocket can be placed on the bottom frame 4 to serve as a seat cushion. When a child sits on the bottom frame 4 and pedals the two sides of the front wheel frame 3 with double feet to apply force alternately, at the moment, the rotating shaft of the universal wheel 7 forms a certain inclination angle with the ground, and the front wheel frame 3 swings left and right to provide forward power through the friction force between the universal wheel 7 and the ground. In the state of the rocking vehicle, the front wheel frame 3 can rotate freely, for example: the bolt can be pulled out, so that the rotating shaft on the front wheel frame 3 can rotate in the sleeve arranged at the bottom of the square main frame 1; and in a baby carriage mode or a shopping cart mode, the rotating shaft is limited in the sleeve through the bolt.
