Described novel labour saving hand barrow, wherein, above-mentioned bottom of frame both sides are respectively arranged with the feet that is used for support trolley.
Described novel labour saving hand barrow, wherein, above-mentioned vehicle frame comprises two handle bars and cross bar, and the termination of handle bar is connected by cross bar, and the section of vehicle frame is and lacks on one side trapezoidal.
A kind of novel labour saving hand barrow that the utility model provides, the center of gravity of wagon box is arranged on the rear of axis wheel, and the line of wagon box center of gravity and axis wheel and the angle by the axis wheel vertical curve at 16 degree between 25 degree, this kind structure makes when hand barrow lifts, the wagon box center of gravity will move forward a segment distance, the center of gravity of wagon box and goods thereof is positioned at by near the axis wheel vertical curve, saved the strength of lifting hand barrow, the user of service only applies a strength forward to hand barrow can easily promote the hand barrow motion, has improved the handling of hand barrow; The mode that vehicle frame in the utility model adopts three bars to be connected makes hand barrow more firm.
Description of drawings
Fig. 1 is the structural representation of novel labour saving hand barrow in the utility model.
The specific embodiment
Below with reference to accompanying drawing, comparatively detailed explanation is carried out in each preferred embodiment in the utility model.
The utility model provides a kind of novel labour saving hand barrow, and hand barrow of the prior art has been carried out scientific and reasonable improvement, has improved the stability of hand barrow, has improved the handling of hand barrow, has saved manufacturing cost.Shown in Figure 1, the novel labour saving hand barrow comprises vehicle frame 1, and this vehicle frame 1 is provided with wagon box 2, and the bottom of vehicle frame 1 is provided with a wheel 3, and the tyre surface of wheel 3 is a little more than vehicle frame 1, and has the gap between wheel 1 and the wagon box 2; The center of gravity of wagon box 2 is positioned at the rear in wheel 3 axle center, the line in wagon box 2 centers of gravity and wheel 3 axle center and the angle by wheel 3 axle center vertical curves at 16 degree between 25 degree.When lifting hand barrow, goods in wagon box and the headstock can move forward to by near the axis wheel vertical curve thereupon, the user of service only applies a strength forward to hand barrow can easily promote the hand barrow motion, and the strength of having saved the lifting hand barrow has improved the handling of hand barrow.
In order further to improve performance of the present utility model, as shown in Figure 1, the line that makes wagon box 2 centers of gravity and wheel 3 axle center is ten octaves with angle by wheel 3 axle center vertical curves, under this kind angle structure, goods during the hand barrow motion in wagon box and the wagon box is positioned at by near the wheel 3 axle center vertical curves, further improved the stability of hand barrow, made hand barrow more laborsaving.On the basis of the foregoing description, the middle front part of vehicle frame 1 bottom is provided with the carriage 4 that is used to install wheel, carriage 4 comprises two stay bearing plates 5, one end of stay bearing plate 5 is arranged on vehicle frame 1 bottom, and stay bearing plate 5 extends internally downwards, the stay bearing plate other end is provided with the axle sleeve 6 that is used to install wheel 3 wheel shafts, is axially symmetric structure between the stay bearing plate 5; And be provided with backing plate 7 between vehicle frame 1 and the wagon box 2, backing plate 7 is arranged on the vehicle frame 1; Improve the firm degree that wheel is installed greatly by above-mentioned improvement, improved the handling of hand barrow.On the basis of above-mentioned three embodiment, vehicle frame and associated components thereof are further improved, support frame 8 before vehicle frame 1 bottom is provided with, should precedingly support frame 8 and be fixed on the axle sleeve 6, front end face of support frame 8 slightly protrudes in vehicle frame 1 front end face before this, and should the preceding front end that supports frame 8 be wedge shape; And be respectively arranged with the feet 9 that is used for support trolley in vehicle frame 1 two bottom sides; Vehicle frame 1 comprises two handle bars 10 and cross bar 11, and the termination of handle bar 10 is connected by cross bar 11, and the section of vehicle frame 1 is and lacks on one side trapezoidal; By foregoing description as can be known, vehicle frame has been saved the manufacturing cost of vehicle frame, and has been improved hand barrow single-piece impregnability by three bar ways of connecting; When making the hand barrow unloading or turning down goods, the front end of preceding support frame is the line contact with ground, has made things convenient for the hand barrow unloading, makes the hand barrow discharge location more accurate.
