Problems solved by technology

Existing folding and portable small carts are ubiquitous, and the folding is not convenient enough. After folding, the volume is large (compared to the same effective carrying volume), cannot be fully linked, and the overall rigidity is poor, the carrying capacity is small, and there is no automatic locking agency, not even safe enough

Embodiment Construction

[0009] See figure 1 The present invention develops a foldable portable trolley and takes the following steps:

[0010] The folding portable trolley is connected to a rectangular open basket 1 with a metal frame hinge. The two sides of the rectangular open basket 1 are connected with four-link 2 components to form a movable hexahedron. A rectangular cloth pocket is hung on the hexahedral frame. A pull-out awning 4 is installed, four wheels 5 are installed on the four corners of the lower end of the main frame, a handle 6 and a front pocket 7 are arranged on the front side of the main frame, and an automatic lock mechanism and a safety lock 3 are arranged at the lower end. A rear tail basket 8 is provided on the rear side.

[0011] The bottom of the upper opening rectangle of the automatic lock mechanism is connected by two metal frames with hinges to form a rectangular plate, and the position of the hinge's rotation center is lower than or equal to the horizontal position of the r...

Abstract

The invention provides a portable foldable trolley. The portable foldable trolley is characterized in that a rectangular-opened basket is formed by connecting a metal frame through hinges; two sides of the rectangular-opened basket are connected through four-bar linkage assemblies to form a movable hexahedron; a rectangular cloth pocket is hung on a hexahedron frame and a drawing type sunshade is also arranged on the hexahedron frame; four wheels are mounted on four corners of the lower end of a main frame; a handle and a front bag are arranged at the front side of the main frame; an automatic locking mechanism and a safety lock are arranged at the bottom end of the main frame; a rear tail basket is arranged at the rear side of the main frame; the bottom, which is upwards opened like a rectangle, of the automatic locking mechanism is subjected to connection of two metal frames by hinges to form a rectangular plate; the position of the gyration center of the hinge is lower than or equal to the horizontal position of the rotating center line of the rectangular plate. The portable foldable trolley has the advantages of being simple in structure, convenient, being small in size after folding, lightweight, capable of being dragged, high in overall rigidity during use, large in loading capacity, automatic to lock and unlock, safe and reliable, novel and nice in appearance and has the linkage performance.

Description

Technical field [0001] The invention relates to a small cart, in particular to a foldable portable small cart. technical background [0002] The cart is a convenient cart. Can be used to carry things, or for children to ride. A tool commonly used in daily life, especially leisure, travel, shopping, delivery, and even business trips. Existing foldable and portable small pull carts are common. They are not convenient enough to fold. After being folded, they are large (compared to the same effective carrying volume), cannot be fully linked, and have poor overall rigidity, small carrying capacity, and no automatic locking Institutions are not even safe enough. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings and provide a foldable portable trolley, which is extremely convenient, linked, small in size after folding, light in weight, can be towed, and has excellent overall rigidity in use. Heavy load, automatic lock, automa...
