When the multipurpose folding stroller is in the stroller operating position, the pet box or the pet seat can be arranged on the bracket 1-1, and the multipurpose folding stroller is a pet stroller, as shown in fig. 6. A shopping basket may also be provided, in which case the multipurpose collapsible cart is a shopping cart (not shown in this embodiment).
When the multipurpose folding cart is positioned at the working position of the small trailer, a shopping basket, a storage basket and a luggage box can be arranged between the luggage rack 2 and the bracket 1-1 according to requirements or goods can be directly placed so as to meet different use requirements.
The multifunctional trolley can solve the problem that the existing trolley has single function, can be converted into a multifunctional trolley, and greatly improves the utilization rate of the whole trolley.
As shown in fig. 7 to 10, an embodiment is illustrated in which the pet car is directly converted into a small trailer with a storage box. A pet box 4 is arranged on the bracket 1-1, and the bottom of the pet box 4 is fixedly connected with the bracket 1-1 through an inserting bag or fixedly assembled through an auxiliary connecting mechanism. When the multipurpose folding cart is in the working position of the cart, the multipurpose folding cart is used as a pet cart, and a pet can be placed in the pet box 4 and pushed out. When the folding type pet car needs to be converted into a small trailer, the locking of the push rod locking mechanism is released, then the push rod assemblies 1-4 are pressed downwards to realize the folding of the car frame 1, in the folding process, the luggage rack locking mechanism 3 is triggered by the push rod assemblies 1-4 to be unlocked automatically, the luggage rack 2 is turned forwards and opened under the action of self weight, at the moment, the front side surface of the pet box 4 rotating along with the bracket 1-1 is turned downwards gradually and falls on the luggage rack 2, at the moment, the pet car is converted into the small trailer, and the pet box 4 is used as a storage box so as to transport articles.
The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalent substitutions or equivalent transformations fall within the scope of the present invention.
