Detailed description of the invention
see Fig. 1 to Figure 11, this example provides a kind of folding children's barrow, and it comprises the trolley rack with deployed condition and folded state, one group of front component 1 and two groups of wheel assemblies 2, for trolley rack being locked in the lockout mechanism of deployed condition.
trolley rack comprises side stand 3 in both sides, be arranged on cross frame between the side stand 3 of both sides.The push rod 31 that side stand 3 comprises front-wheel support 30 further, bottom and the upper end of front-wheel support 30 rotate to be connected, upper end and the upper end of front-wheel support 30 rotate the rear wheel support 32 be connected, the handle 33 being arranged on push rod 31 upper end.Be positioned at the non-parallel setting of described front-wheel support 31 of both sides, it is roughly large in upper end distance therebetween, and lower end is arranged apart from little arc therebetween, is positioned at the push rod 33 also non-parallel setting of both sides, roughly in lower end, distance is large therebetween for it, and upper end is arranged apart from little arc therebetween.Front component 1 comprises front-wheel 10, front-wheel joint 11, and this front-wheel joint 11 comprises the front-wheel support attaching parts 110 that two ends are rotationally connected with the bottom of the front-wheel support 30 of both sides respectively.Further, the bottom of front-wheel support 30 has the first inclined-plane A, the both ends of front-wheel support attaching parts 110 have the second inclined-plane B coordinated with the first inclined-plane A respectively, the bottom of front-wheel support 30 and the both ends of front-wheel support attaching parts 110 rotate respectively by the first pivot a through the first inclined-plane A and the second inclined-plane B and are connected, first inclined-plane A and the second inclined-plane B and the mutual out of plumb of the first pivot a are bottom-up outwardly state between two first inclined-plane A or between two second inclined-plane B.The upper end of front-wheel support 30 is fixed with joint 300, this joint 300 has the 3rd inclined-plane C, the upper end of rear wheel support 32 has the 4th inclined-plane D coordinated with the 3rd inclined-plane C, the upper end of rear wheel support 32 is connected by rotating through the second pivot b of the 3rd inclined-plane C and the 4th inclined-plane D with joint 300,3rd inclined-plane C and the 4th inclined-plane D and the mutual out of plumb of the second pivot b are the state of inward collapsible from bottom to top between two the 3rd inclined-plane C.Arranging of described two groups of inclined-planes can make when folding, the front-wheel support 30 of both sides, and rear wheel support 32 all inwardly laterally draws in relatively, thus reduces lateral dimension.In addition, joint 300 can also have the 5th inclined-plane, and the lower end of push rod 31 has the 6th inclined-plane coordinated with the 5th inclined-plane, and the bottom of push rod 31 is connected by rotating through the 3rd pivot c on the 5th inclined-plane and the 6th inclined-plane with joint 300.
trolley rack also comprises the bottom supporting rod 4 that leading section and front-wheel joint 11 are rotationally connected by the horizontal pivot 4a that extends in the horizontal direction.Cross frame comprise be arranged on both sides rear wheel support 32 between and can the rear cross member 5 of horizontal folding, rearward end and the rear cross member 5 of bottom supporting rod 4 are rotationally connected.
further, rear cross member 5 comprises and is positioned at middle part after go-cart, the vertical connecting rod 50 vertically extended, be successively set on the upper connecting base 51 on vertical connecting rod 50 from top to bottom, middle Connection Block 52 and lower connecting base 53, the first cross bar 54 and the second cross bar 55 that inner end is rotationally connected with relative two sides of upper connecting base 51 respectively, the 3rd cross bar 56 that inner end is rotationally connected with relative two sides of lower connecting base 53 respectively and the 4th cross bar 57, the first brace 58 and the second brace 59 that upper end is rotationally connected with relative two sides of middle Connection Block 52 respectively, first cross bar 54, second cross bar 55, 3rd cross bar 56 and the 4th cross bar 57 are all horizontally disposed with, and their outer end all rotates with the rear wheel support 32 of homonymy and is connected, first brace 58 rotates with the 3rd cross bar 56 and the 4th cross bar 57 respectively with the bottom of the second brace 59 and is connected.Described being rotationally connected all is connected by pivot.First cross bar 54, second cross bar 55, the 3rd cross bar 56, the 4th cross bar 57, first brace 58 and the second brace 59 are arc.The rearward end of bottom supporting rod 4 is connected by the pivot extended in the horizontal direction with upper connecting base 51, and is provided with handle 6 in the rear end of bottom supporting rod 4.In addition, lower connecting base 53 is provided with step 9.
further, cross frame also comprises the push rod stull 7 between the push rod 31 being arranged on both sides, this push rod stull 7 comprises rotate the first singletree 70 of connecting and the other end of the second singletree 71, first singletree 70, second singletree 71, an end and rotates with the upper end of the push rod 31 of both sides respectively and be connected.Lockout mechanism comprises and being arranged between the first singletree 70 with the second singletree 71 for by the two relative lock cell 8 locked.
this routine children trolley folding process is as follows:
the first step: unlocked by the lock cell 8 at push rod stull 7 place, then overturns push rod 31 entirety forward, as shown in Figures 6 and 7, draws close completely to push rod 31 and front-wheel support 31;
second step: see Fig. 7, handle 6 is upwards mentioned, bottom supporting rod 4 rotates around horizontal pivot 4a, pull front-wheel joint 11 to rotate to rear wheel support 32 direction simultaneously, first inclined-plane A is rotated relative to the second inclined-plane B, the front-wheel support 30 of both sides is inwardly laterally relatively drawn in while drawing close to rear wheel support 32 rotation, at handle 6 to while pull-up, rear cross member 5 laterally draws in, the rear wheel support 32 of both sides is driven to draw in centre, simultaneously owing to being coordinated by inclined-plane between rear wheel support 32 with joint 300, when rear wheel support 32 is drawn close to front-wheel support 30, rear wheel support 32 self also inwardly laterally draws in relatively relative to front-wheel support 30, finally as shown in FIG. 10 and 11, as can be seen from Fig. 10, after folding, the front-wheel support being positioned at both sides is all relative with rear wheel support to be drawn close to some extent, rear wheel support 32 and push rod 31 are all positioned at the inner side of front-wheel support 30, compared with the volume before folding, after folding, cart body is long-pending reduces greatly, be convenient to packaging, transport and carry.
the present embodiment center tap is fixed on front-wheel support, and what push rod and rear wheel support rotated is connected on joint.As a change programme of the present embodiment, joint is fixed on the bottom of push rod, now, and being rotationally connected by pivot and this joint with rear wheel support of front-wheel support.The folding process of this kind of structure is same as the previously described embodiments.
above to invention has been detailed description; its object is to allow the personage being familiar with this art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; the equivalence change that all Spirit Essences according to the present invention are done or modification, all should be encompassed in protection scope of the present invention.
