Detailed description of the invention
With specific embodiment, the structure of the fast folding handbarrow of the present invention is described in detail below in conjunction with the accompanying drawings.
Fig. 1-Fig. 3 show the structural representation of an embodiment of fast folding handbarrow of the present invention, shown in figure
It it is the different conditions of handbarrow under 3 kinds of different transport mode.
As it can be seen, this fast folding handbarrow includes car body 10, wheel 11 and is positioned on rear side of car body 10, for promoting
Or pull the push rod 12 of described car body.Wheel 11 is each provided with two at the front and rear of car body 10, wherein, is positioned at front portion
Two is BOGEY WHEEL, and two that are positioned at rear portion is universal wheel.Push rod 12 is in the U-shaped stood upside down, by the vertical rod 12a and the position that are positioned at both sides
Cross bar 12b composition in upper end.
Car body 10 includes a horizontally disposed vehicle frame 10a and is arranged on gear frame 10b (or baffle plate) of vehicle frame front end, vehicle frame
Anterior frame 10a is located in the connecting shaft 13 between anterior two wheels of car body 10；The both sides, rear end of vehicle frame are cut with scissors with sleeve 14 respectively
Connecing, each sleeve pipe 14 is set on the vertical rod 12a of corresponding side and can move up and down along vertical rod 12a.At described sleeve pipe 14
On be provided with can the knob 15 of the lock collar 14 position on vertical rod 12a.The bottom of two vertical rod 12a is by an optical axis 16 even
Connecing, the two ends of optical axis 16 are positioned at below sleeve pipe 14.
It is respectively arranged with slideway 17 in the both sides of vehicle frame 10a, a slide bar 18 is respectively installed in each slideway 17；Each cunning
Bar 18 one end with a crank 19 respectively is connected, and the other end of crank 19 is hinged on optical axis 16.
In the bottom of the left and right sides of vehicle frame 10a, one the 1st limited block 20 is respectively installed, the 1st limited block 20 is provided with
Alignment pin 21, alignment pin 21 is connected with one the 1st limited block switch knob 23 by brake cable 22.1st limited block switch knob 23 is pacified
It is contained in the lower rear of vehicle frame 10a.
As the improvement to said structure, in the bottom of both sides, vehicle frame 10a rear portion, one the 2nd limited block 24 is respectively installed,
2nd limited block 24 is hinged with sleeve pipe 14, and the two ends, rear portion of vehicle frame 10a are packed on the 2nd limited block 24.At the 2nd limited block 24
Having groove in the middle part of bottom, under the four-wheel flat board transport mode shown in Fig. 1, the 2nd limited block 24 is erected at by described groove
On optical axis 16.It addition, be respectively provided with a postive stop baffle 25 in the both sides, rear portion of vehicle frame 10a, postive stop baffle 25 has front apron
With backboard (figure does not marks), under four-wheel flat board transport mode, it is used for limiting relatively rotating of vertical rod 12a and vehicle frame 10a.
Although it addition, figure does not shows, a dismountable flat board can also be installed on vehicle frame 10a, constitutes whole support
Plane, in order to the goods that transportation volume is less.
The handbarrow of said structure can be deformed into 3 shown in Fig. 1-Fig. 3 kind Transportation Model.Specific as follows:
1, four-wheel flat board transport mode:
As it is shown in figure 1, in this case, the 2nd limited block 24 is erected on optical axis 16, and vehicle frame 10a is relative to vertical rod 12a's
Position is locked by knob 15, and spacing by postive stop baffle 25.Now, vehicle frame 10a is horizontally disposed with, and goods is placed on vehicle frame
On 10a, promote push rod 12, can transport.
2, four turbine/lever transport mode:
Under four-wheel flat board transport mode, unclamp knob 15, be moved upward to close along vertical rod 12a by the rear portion of vehicle frame 10a
Right position is put, locking knob 15, forms four turbine/lever transport mode, as shown in Figure 2.
3, two turbine/lever transport mode:
Under four turbine/lever transport mode, unclamp knob 15, utilize the inertia of push rod self drive optical axis 16 and push open calmly
Position pin, makes optical axis 16 enter in the groove of the 1st limited block 20, it is achieved location.Now crank 19 folds, and two universal wheels are packed up, shape
Become two turbine/lever transport mode shown in Fig. 3.
Under two turbine/lever transport mode, when needing to change other pattern, pull the 1st limited block switch knob 23, pass through
Brake cable pulls alignment pin 21, alignment pin 21 to rise, and no longer forms optical axis 16 and limits, now promotes optical axis 16 so that it is depart from the 1st
Limited block 20, pulls back two universal wheels, is i.e. convertible into other Transportation Model.
Furthermore it is also possible to install a removable hoistable platform 26 on vehicle frame 10a, described hoistable platform 26 is by plane four
Linkage and screw-drive mechanism composition.Described screw-drive mechanism includes: be removably mounted on two inside vehicle frame 10a
Guide rod 27, the slide block 28 being separately mounted on every guide rod 27, the batten 29 being erected on two slide blocks 28 and a screw rod 30, described
One end of screw rod 30 is removably mounted on the middle part of vehicle frame 10a, and the middle part of screw rod 30 is installed by swivel nut (not shown)
On batten 29, the other end of screw rod 30 is positioned at vehicle frame 10a rear portion and is connected with crank 31.
Described four-bar linkage include a horizontal frame 32 and 4 support bars 33, every two support bars 33 be one group and
Middle part is hinged in X-shaped, and the two ends, left side of the upper end of two groups of support bars 33 support level framework 32 respectively and two ends, right side, two groups are propped up
Strut 33 is positioned at two lower ends of Vehicular body front and is removably mounted on vehicle frame 10a, and two lower ends being positioned at rear vehicle are solid
It is contained on batten 29.
Furthermore it is also possible to install gripper shoe (not shown) on described horizontal frame, constitute whole supporting surface, in order to fortune
The goods of defeated small volume.
By manual drive/rotation crank 31, utilize screw-drive mechanism to promote batten 29, and then drive plane four bar machine
Structure moves to right near two fulcrums of rear vehicle, it is achieved the lifting of article carrying platform.
Vehicle frame 10a and hoistable platform 26 in the present invention can be made up of aluminium section bar, in the case of meeting requirement of strength,
The weight of whole car body can be alleviated.Turning of different transport mode is realized relative to the position of push rod 12 by changing vehicle frame 10a
Change, to be applicable to the carrying of the goods of difformity, weight.Hoistable platform 26 can be used for promoting heavier goods, alleviates manpower
Work.Can choose whether hoistable platform is installed according to different use demands.
