Side frame is fixed two or more sets with its both ends through hollow seat 8 by a root long inclined tube 9 by articulated joint 6 two After the coplanar X cross pipes member hinges that individual short inclined tube 7 forms, then be connected with upper bracket 13 and undersetting 19.Wherein, Long one end of inclined tube 9 is connected with undersetting 19, and the other end is connected with articulated joint 6, it is middle then through the strip hole in hollow seat 8 and its It is connected；And then wherein one one end is riveted on upper bracket 13 the two short inclined tube 7 that the both ends of hollow seat 8 are fixed, Ling Yigen One end be then riveted on hinge head 6.It is similarly, separately one or more groups of that also identical mode has linked together.During opening, with flat Face X intersect tube assembly by hollow seat 8 with being rotated centered on the long junction of inclined tube 9, and drive its corner rotating around upper bracket 13, under The junction of bearing 19 and two articulated joints 6 rotates, the spacing place arrived to long inclined tube 9 in the strip hole of hollow seat 8.During folding, Coplanar X intersects tube assembly by hollow seat 8 with being rotated centered on the long junction of inclined tube 9, and drives its corner rotating around upper bracket 13rd, the junction of undersetting 19 and two articulated joints 6 rotates, be parallel to each other and put off till to long inclined tube 9 and short inclined tube 7 together with.

Entirety that the side arm, after-frame are linked to be by two upper brackets 13 at entablature 12 and both ends respectively and sill 14 with The entirety that two undersettings 19 at both ends are linked to be, pass through the outer guide pipe 10 and set that are connected on undersetting 19 and the connection in it The interior guide pipe 11 of upper bracket 13 forms.During opening, side arm, after-frame intersect the effect opened to both sides of tube assembly in coplanar X It is lower to former and later two direction integral translations；Simultaneously entablature 12 and two upper brackets 13 being connected by interior guide pipe 11 to It is pushed down into outer guide pipe 10, being pressed onto outer guide pipe 10 to upper bracket 13 stops.During folding, side arm, after-frame are in coplanar X cross pipes Component is to integral translation folding under the drive collapsed together；Entablature 12 is led with two upper brackets 13 being connected by interior simultaneously It is lifted up to pipe 11 out of outer guide pipe 10, is parallel to each other to long inclined tube 9 and short inclined tube 7 and puts off till a start-stop.

Wheel is connected on vehicle wheel frame 16 by bearing pin, and vehicle wheel frame 16 recycles wheel quick-release mechanism solid with undersetting 19 It is fixed.Therefore, wheel is synchronized with the movement with undersetting 19 in folding, opening.

Rod assembly is to connect lower pull bar 3 by pin by the draw-bar seat 20 being fixed on sill 14, and with inserting it Inner upper connecting rod 2 and the handle 1 being fixed on upper connecting rod 2 form.Wherein upper connecting rod 2 when hand buggy is opened from the drop-down of insertion Extracted in bar 3 and locked consequently facilitating pulling a cart；When hand buggy collapses, the lock first unclamped between upper connecting rod 2 and lower pull bar 3 is i.e. flexible Mechanism, then upper connecting rod 2 is pushed into lower pull bar 3, it is easy to pack.

Hoodle drag link mechanism, when opening, lifting upwards of shaking hands is caught, drive upper connecting rod total integral upward, until V-type Double end hoodle 30 is caught in the hole of the lower upper end of pull bar 3, plays position-limiting action.It is spacing to be positioned the institute of piece 29 for the bottom of fore-set 31 simultaneously. During contraction, button 24 is first pressed, drives push rod 25, shift fork 28 to move downward, dual head spring 30 is taken off out of lower pull bar 3 hole Go out, release lockup state.Handle is pushed down on simultaneously on earth again, and release button 24.

Steel ball drag link mechanism, when opening, lifting upwards of shaking hands is caught, drive upper connecting rod total integral upward, until embedding Enter the steel ball 38 in upper connecting rod 2 to be caught in the second spacing hole of the lower upper end of pull bar 3, play position-limiting action.During folding, first press by Button 24 makes push rod 25 promote steel ball seat 28 to move downward, and steel ball 38 is slided into out of steel ball seat 48 stopper slot in solution locked groove, So that steel ball 38 is deviate from out of lower pull bar 3 the second spacing hole, lockup state is released.Handle is pushed down on simultaneously on earth again, And release button 24.

There is the raised gear groove match with 33 corresponding side of drawhead of a circle gear in the outside of two gear seats 35, and The withstanding on together tightly in the presence of gear spring 34 between two gear seats 35.During rotating tension bar, it is connected to lower pull bar 3 Drawhead 33 together drives its Inner gear spring 34 and the gear seat 35 at both ends to be rotated together around bolt 36.And pull bar Seat 20 does not rotate due to being integrally fixed on vehicle frame sill, therefore in the presence of gear spring 34, the shelves on gear seat 35 Position is raised with being rotated into gear groove different on drawhead 33, so that pull bar stops in different rotation positions.
