Abstract
The low density cargo power trolley that the utility model provides, comprise L-type loading car body, two land wheel is installed on loading Vehicular body front, hand-pushing handle is arranged at loading rear vehicle, one Rotary support is hinged is connected in loading car body dorsal midline place, its jointed shaft is provided with torsion spring, and Rotary supports and be provided with expansion lockout mechanism between loading car body.The two places in Rotary and front are taken turns and are formed ground supported at three point, and Rotary supports and form three-dimensional gusseted between loading car body, promote more laborsaving, stable when cargo capacity is more.
Description
Technical field
The utility model relates to hand barrow, and this hand barrow is small capacity double ground wheel barrows, is mainly used in place group article transfer two ground wheeled trolleys such as market, workshop, office.
Background technology
The hand barrow that the application relates to is more the load-carrying vehicle that group's article are moved in the places such as market, workshop, office, its typical construction is: main component is L-type loading car body, two land wheel is arranged on loading Vehicular body front, loading rear vehicle arranges hand-pushing handle, portioned product adopts front end L-type support to the structure of main load-carrying vehicle folded body in the design, takies volume to reduce car body.This kind of hand barrow forms simple, uses portable, if but heap send article more, heavier time, people should exert oneself go-cart, and also will praise car body very with strength, and ensure that article do not fall, require great effort very much, common people are difficult to lastingly.
Summary of the invention
Goal of the invention of the present utility model is to provide one to alleviate praises strength, promote also very labour-saving low density cargo power trolley when charging burden is larger.The low density cargo power trolley technical scheme that the utility model provides, its main technical content is: a kind of low density cargo power trolley, comprise L-type loading car body, two land wheel is installed on loading Vehicular body front, hand-pushing handle is arranged at loading rear vehicle, one Rotary support is hinged is connected in loading car body dorsal midline place, and its jointed shaft is provided with torsion spring, and Rotary supports and be provided with expansion lockout mechanism between loading car body.
In above-mentioned overall technical architecture, when supporting for avoiding three-wheel, loading car body front end is under pressure causes car body unstable and the use problem of overturning, the front of two land wheels, loading lower car body erecting frame are hinged with front support stand, between front support stand and loading car body, tractive has extension spring, front support stand is hinged with the operation pull bar of guiding hand-pushing handle into, and erecting frame is provided with spacing catch when front support stand front support is launched.
Low density cargo power trolley technical scheme disclosed in the utility model, after Rotary supports and is launched by the loading car body back side, form the back support of loading car body, the two places in Rotary and front are taken turns and are formed ground supported at three point, Rotary supports and form three-dimensional gusseted between loading car body, when especially cargo capacity is more, and movement that can be stable, and significantly reduce loading car body praise strength, reach loading and move labour-saving technical purpose.Rotary supports also can folding voluntarily, and the Rotary after folding is affixed on the loading car body back side, and between two land wheels, additionally takes up room hardly, the same with existing common hand barrow.If front support stand can also actv. eliminate three-wheel support time front end concentrate the technical matters of overturning during topping-up, eliminate use in safety hazard.

Fig. 3 is the A-A position side-looking constructional drawing of Fig. 1.
Detailed description of the invention
The low density cargo power trolley that the utility model provides, comprises L-type loading car body 1, and two land wheel 2 coaxial line is installed on loading car body 1 front part sides, and the framework at loading car body 1 rear portion forms hand-pushing handle 3.One Rotary supports 5 hinge mounted in loading car body 1 dorsal midline position, and its lower end is preferably installed by universal-joint 11 and connected Rotary 4, and the jointed shaft of Rotary support 5 is provided with torsion spring 14, and Rotary supports 5 and relies on the recovery elastic force of torsion springs 14 to paste contracting loading car body 1 back side voluntarily; Rotary supports between 5 and loading car body and is provided with expansion lockout mechanism.Described expansion lockout mechanism can have multiple implementation structure, and one is adopt to be articulated with between Rotary support 5 and loading car body 1 to strut spacing binodal connecting rod, and as shown in Figure 2, this enforcement forms employing limiting lock structure.Rotary supports 5 tops and is provided with lock ring 12, the back side of loading car body 1 is provided with limiting lock 13, Rotary supports in 5 expansion, its top lock ring 12 is close to limiting lock, until when completing expansion, lock ring 12 is also taken advantage of a situation and slipped into dead bolt fore shaft 15, lock lock ring 12, location is worn by fore shaft dead bolt 15, now form the three-wheel ground supports of two land wheel 2 and Rotary 4, loading car body 1 and Rotary support the triangle dimensional support of 5, thus greatly alleviate, especially large matter-loading amount time praise strength.
During for overcoming two land wheel 2 and the support of Rotary 4 three-wheel, car body caused by the initial set stacked items of loading car body 1 front end is unstable, rock, the technical matters of even overturning, the erecting frame 10 of the loading car body 1 in two land wheel 2 fronts is hinged with front support stand 6, between front support stand 6 and loading car body 1, tractive has extension spring 7, operation pull bar 9 is articulated with front support stand 6, and guide hand-pushing handle 3 into, outside promotion operation pull bar 9, the outer upset of front support stand 6, cross the lower dead point of reset tension spring, be locked on the spacing catch 8 on erecting frame, additional support is formed in loading car body 1 front end, car body is steadily supported on the ground, ensure stability when concentrating loading in loading car body front end.
