Detailed description of the invention
Below in conjunction with drawings and Examples, invention is described in detail.
As shown in Figure 1,2 and 3, the multi-purpose wheelbarrow that the present invention proposes, comprise vehicle frame 1, vehicle frame is made up of internal frame 2 and outrigger 3; The articulated sleeve pipe 4 that can rotate in gap between internal frame 2 and outrigger 3 in junction of described internal frame 2 and outrigger 3 both upper ends thereof, penetrate between two sleeve pipes 4 and a U-shaped armrest support 5 is installed, the two ends, bottom of this handrail are separately installed with universal trailing wheel 6, laterally be provided with a locking bar 7 between universal trailing wheel 6, also hingedly on universal trailing wheel 6 be provided with a brake shoes 24.
The bottom of internal frame 2 is provided with handrail jack, handrail jack comprises the lock 8 of the bottom being fixed on internal frame 2 for a pair, lock 8 is provided with the screens groove 9 that coupling locking bar 7 snaps in, and the inside of lock 8 has flexible lock structure, flexible lock structure has tapered end and to be arranged between two locks and the treadle 10 driving tapered end to stretch up and down, and treadle 10 is provided with the pedal 11 be arranged between two locks.Internal frame 2 two ends are also provided with the first support limit plate 12, and this support limit plate 12 is provided with the position-limited trough 13 coordinating locking bar 7 to insert.The lower end of outrigger 2 is provided with a countershaft, in rotating shaft, cover has front wheel carrier 14, front wheel carrier 14 is provided with go-cart front-wheel 15, front wheel carrier 14 is provided with a dowel hole, correspond to outrigger described in this dowel hole and be provided with front-wheel automatic limiting mechanism, front-wheel automatic limiting mechanism comprises the lifting bar 16 being laterally arranged on outrigger lower end, and lifting bar 16 is provided with pedals plate 17, pedal plate 17 and have strut bar 18 for lifting lifting bar 16, lifting bar 16 is provided with elasticity pin 19 and coordinates described dowel hole.Front wheel carrier 14 also installs drive bevel gear 20, and the lower end of outrigger is hinged is installed with divider 21, and the two ends of divider 21 are provided with the driven wheel of differential 22 of the described drive bevel gear 20 of coupling engagement.Armrest support 5 is fixed with handle 23, handle 23 bottom is provided with the clip be fixed on armrest support, and the external diameter of this clip is greater than the internal diameter of described sleeve pipe.
The ingenious part of design of the present invention is following 3 points, first, the lock structure that the design of handrail jack make use of a traditional spring lock improves, treadle 10 can drive synchronous the moving up and down of the tapered end on both sides, and have spring in lock structure, open or close (stretch out or inside contract) as long as all overcome spring force, locking bar snaps onto in screens groove 9, locking bar is stuck in groove inside by tapered end automatically, and when push down on the pedal, treadle is also pressed down, tapered end can inside contract, decontrol locking bar, the universal front-wheel on such both sides just can move on sleeve pipe along with armrest support and the turning effort of adjoint sleeve pipe, during the junction of slip outrigger and internal frame always, just complete one 90 degree fan-shaped, and locking bar is slided in position-limited trough 13.
Second, in rotating shaft on outrigger, cover has front wheel carrier 14, front wheel carrier 14 is provided with go-cart front-wheel 15, front wheel carrier 14 with go-cart front-wheel 15 towards doing fan-shaped rotary about both sides, be combined with front-wheel automatic limiting mechanism, at front-wheel in the process launched, the front end of the elasticity pin of automatic limiting mechanism is along with the guide groove movement on front wheel carrier, when front-wheel launches completely (mode of operation is go-cart front-wheel 90-degree rotation), elasticity pin drops in the dowel hole of money wheel carrier, form location, make the expansion that go-cart front-wheel cannot continue, form self-locking, when needing to draw go-cart front-wheel in, only need to stir with pin to pedal the expansion automatic limiting mechanism of plate with regard to quick releasable go-cart front-wheel, and then allow go-cart front-wheel gain freedom.
3rd, the driving cone pulley of front wheel carrier and the driven bevel wheel of divider hinge point, mutual left and right is interrelated, when divider completes the fan shape moving of 90 degree, front wheel carrier is also complete, and 90 degree fan-shaped is synchronized with the movement, and designs very ingenious, so when will receive go-cart front-wheel, fold divider as long as receive.
Above-described embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, patent of the present invention and protection domain should be as the criterion with appended claims.
