Specific embodiment

A kind of super portable folding dolly, including handrail 1, pedal, front-wheel 2, trailing wheel 3, the pedal by pedal front portion 4, step on Postlaminar part 5 is constituted, and being in by rotating shaft 6 between pedal front portion, pedal rear portion can be to the collapsible connection in bottom surface；Handrail and rotary components 7 connections, make handrail can horizontal plane direction rotate and rotated with vertical plane direction；The rotary components are fixedly connected with pedal front portion, Rotary components bottom fills front-wheel；Rear end of the trailing wheel loaded on pedal rear portion.

Front-wheel, trailing wheel are in the form mutually staggered after folding.

The rotary components include the first component 8 being fixedly connected with pedal front portion, and the top and the bottom of first component lead to respectively Cross first rotating shaft, the second rotating shaft to be connected with second component 9, third member 10, make second component, the third member can be rotating around first Rotating shaft 13, the second rotating shaft 14 are rotated in vertical plane direction；Second component, third member respectively by the 3rd rotating shaft 15, the 4th turn Axle 16 is connected with the 4th part 11, the 5th part 12, makes the 4th part, the 5th part can be rotating around the 3rd rotating shaft, the 4th rotating shaft Horizontal plane direction is carried out to rotate；4th part is fixedly connected with handrail, and the 5th part is connected with front-wheel.

4th part, the 5th part are coordinated by tongue and groove 16.

Hereinafter describe, be related to the description of vertical plane and horizontal plane, vertical plane refers to drawing plane, and horizontal plane refers to overlook Face（Ground or the face perpendicular to drawing）, face I refers to the lateral surface at pedal rear portion under folded state（The medial surface at pedal rear portion with Pedal front portion fits together）.

Pedal front portion is connected with pedal rear portion by rotating shaft 6, and can be rotated around rotating shaft 6.

Rotary components connection handrail, front-wheel and pedal are anterior, and handrail can rotate to drive the front-wheel to carry out with horizontal plane direction Rotation control direction, it is also possible to the rotation on vertical plane direction is carried out around P1 points, rotation back hand rail can fit with pedal front portion Together into folded state.

Front-wheel is removed and is connected with handrail（By rotary components）Carry out rotation steering outer, it is also possible to be designed to front-wheel in vertical plane Side can carry out the rotation of certain angle around rotary components when being folded up, to control the position of front-wheel after folding（After front-wheel folding, The position of opposite face I：Raised face I, not raised face I and few raised face I planes）.

Front and back wheel can be 2 after first 1（As long as or 1 or many wheels for not interfering of position after ensureing to fold after first 2 Situation）, front and back wheel position is mutually to be staggered after folding.

After folding generally, front and back wheel can form the state of multiple spot stabilization supporting trolley, it is possible in vertical plane side It is inclined upwardly for towing.

Handrail can up and down be stretched with controlled, to adjust the length of handrail.

Front-wheel can be with different with the size of trailing wheel.

Motion principle description on rotary components, but it is not limited to following structure.

As above scheme, rotary components include：First, second, third, fourthth, the 5th part.

1st, second, third part is connected on first component by rotating shaft respectively, and second, third part can be carried out around axle Rotation.

2nd, first component is fixed on pedal front portion, and the 4th part is connected with handrail, and the 5th part is connected with front-wheel.

3rd, the 4th part is connected by rotating shaft with second component, and the 4th part can be horizontally rotated around axle.

4th, the 5th part is connected by rotating shaft with third member, and the 5th part can be horizontally rotated around axle.

5th, the 4th part is coordinated with the 5th part by tongue and groove, it is ensured that the 4th part when needing, the 5th Part synchronous interaction is horizontally rotated.

Motion explanation：

Motion state such as schemes -1, figure -2, figure -3, figure -4, figure -5, -6 states of figure.

Figure -1 is state after launching, if front and back wheel is designed as in different size, state can be using figure -4 after expansion Mode, pedal front portion and one angle of pedal rear design.

The description of figure -2 is to fold pilot process, and pedal is anterior, and point of rotation P2 is rotated around the shaft with pedal rear portion, while Handrail is rotated around rotary components P1.Spinning movement can be using artificial or power drive.

The description of figure -3 is state after the completion of folding, and front and back wheel forms support after folding.Front-wheel is if desired（In order to not protrude Or few raised face I）Front-wheel can also be designed in jackknife action, the rotation of certain angle can be carried out around rotary components, before making Wheel is not protruded or few raised face I, such as the state of figure -5.

Dolly can hold handrail and tow lifting or inclines, such as scheme -6.

Expansion is rotated according to direction opposite above.

Folded state and deployed condition have the lockable mechanism of stabilization.
