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

Folding type portable small handcart

Technical field

The present invention relates to a kind of littlely to pull a cart, particularly relate to a kind of folding type portable small handcart.

Technical background

Little pulling a cart is one dolly easily.Can be used for loading or children's ride-on.In daily life, particularly lie fallow, tourism, shopping, deliver goods, a kind of instrument conventional in even going on business.The little of existing folding portable type is pulled a cart, and ubiquity, folding convenient not, and after turning up, volume large (identical effective delivery volume is compared), can not interlock entirely, and integral rigidity is poor, and bearing capacity is little, and be not automatically locked mechanism, safe even not.

Summary of the invention

The object of the invention is to overcome above weak point, provide a kind of folding type portable small handcart, this waggon is very convenient, interlock, and after folding, size is little, lightweight, can tow, use middle overall rigidity fabulous, load-carrying is large, is automatically locked, automatic unlocking, safe and reliable, novel, attractive in appearance.

The object of the invention is to be realized by following technical scheme, have developed a kind of folding type portable small handcart: this folding type portable small handcart, a rectangular aperture bicycle basket is become with metal framework chain connection, in rectangular aperture bicycle basket both sides, double leval jib assembly connects into a movable hexahedron, hexahedral framework hangs the cloth pocket of a rectangle and drawing and pulling type awning is set, four wheels are installed at four angles of main body frame lower end, handle and front bag are set in the front side of main body frame, low side arranges automatic lock mechanism and safety lock, rear side arranges rear tail basket, the end of the upper shed rectangle of described automatic lock mechanism, is hinged by two metal frameworks, form the plate of one piece of rectangle, the position of the center of gyration of hinge is less than or equal to the level attitude of rectangular plate rotary centerline, the left cross bar of described safety lock main body frame underframe fills a fixing latch hook, right cross bar fills a movable latch hook, one end of movable latch hook arranges a lift ribbon.

Described drawing and pulling type awning makes a truncate square cone, in truncate distance cone, area of conter is greater than lower area of conter, at upper area of conter place, hang up the cloth paulin that is less than area of conter, each angle of tilt is each fixes a turning of making by flexible plastic sheet, and there is a rectangular aperture top at turning.

Described handle two fine steel tubes are made, and annular is processed in one end of steel pipe, and installs plastics protector additional, and other end hinge is connected with main body frame, during folded state, and two trailing wheels and handle formation three place touchdown point.

Advantage of the present invention: structure is simple, design science is very convenient, interlock, and after folding, size is little, lightweight, can tow, use middle overall rigidity fabulous, and load-carrying is large, is automatically locked, and automatic unlocking is safe and reliable, novel, attractive in appearance.

Accompanying drawing explanation

Fig. 1 is constructional drawing of the present invention.

Specific embodiment

Have developed a kind of folding type portable small handcart see Fig. 1 the present invention, take following steps:

This folding type portable small handcart, a rectangular aperture bicycle basket 1 is become with metal framework chain connection, in rectangular aperture bicycle basket 1 both sides, double leval jib 2 assembly connects into a movable hexahedron, hexahedral framework hangs the cloth pocket of a rectangle and drawing and pulling type awning 4 is set, four wheels 5 are installed at four angles of main body frame lower end, arrange handle 6 and front bag 7 in the front side of main body frame, low side arranges automatic lock mechanism and safety lock 3, and rear side arranges rear tail basket 8.

The end of the upper shed rectangle of described automatic lock mechanism, is hinged by two metal frameworks, forms the plate of one piece of rectangle, and the position of the center of gyration of hinge is less than or equal to the level attitude of rectangular plate rotary centerline.

The left cross bar of described safety lock main body frame underframe fills a fixing latch hook, right cross bar fills a movable latch hook, one end of movable latch hook arranges a lift ribbon.

Described drawing and pulling type awning 4 makes a truncate square cone, in truncate distance cone, area of conter is greater than lower area of conter, at upper area of conter place, hang up the cloth paulin that is less than area of conter, each angle of tilt is each fixes a turning of making by flexible plastic sheet, and there is a rectangular aperture top at turning.

Described handle 6 two fine steel tubes are made, and annular is processed in one end of steel pipe, and installs plastics protector additional, and other end hinge is connected with main body frame, during folded state, and two trailing wheels and handle formation three place touchdown point.

In addition, to invention is not meant by schematic diagram and specification sheets limit to, can change to some extent under the prerequisite not departing from design aim.
