Specific embodiment
The structure of fast folding trolley of the invention is described in detail in the following with reference to the drawings and specific embodiments.
Fig. 1-Fig. 3 show the structural schematic diagram of one embodiment of fast folding trolley of the present invention, as shown in the figure
For the different conditions of trolley under 3 kinds of different transport modes.
As shown, the fast folding trolley include car body 10, wheel 11 and positioned at the rear side of car body 10, for pushing
Or pull the push rod 12 of the car body.Wheel 11 is each provided with two in the front and rear of car body 10, wherein positioned at front
Two are carrying roller, and two positioned at rear portion are universal wheel.Push rod 12 is in the U-shaped to stand upside down, by the upright bar 12a and the position that are located at two sides
Cross bar 12b in upper end is formed.
Car body 10 includes a horizontally disposed vehicle frame 10a and gear frame 10b (or baffle) for being mounted on vehicle frame front end, vehicle frame
Front frame 10a is located in the connecting shaft 13 between 10 front of car body, two wheel；The rear end sides of vehicle frame are cut with scissors with sleeve 14 respectively
It connects, each casing 14 is set on the upright bar 12a of corresponding side and can move up and down along upright bar 12a.In described sleeve pipe 14
On the knob 15 that can lock position of the casing 14 on upright bar 12a is installed.The lower part of two upright bar 12a is connected by an optical axis 16
It connects, the both ends of optical axis 16 are located at below casing 14.
It is respectively arranged with slideway 17 in the two sides of vehicle frame 10a, a slide bar 18 is respectively installed in each slideway 17；Each cunning
Bar 18 is connect with one end of a crank 19 respectively, and the other end of crank 19 is hinged on optical axis 16.
One the 1st limited block 20 is respectively installed in the lower part of the left and right sides of vehicle frame 10a, is equipped on the 1st limited block 20
Positioning pin 21, positioning pin 21 are connect by brake cable 22 with one the 1st limited block switch knob 23.1st limited block switch knob 23 peace
Mounted in the lower rear of vehicle frame 10a.
As the improvement to above structure, one the 2nd limited block 24 is also respectively installed in the lower part of the rear portion vehicle frame 10a two sides,
2nd limited block 24 is hinged with casing 14, and the rear portion both ends of vehicle frame 10a are packed on the 2nd limited block 24.In the 2nd limited block 24
It is provided with groove in the middle part of lower part, under four-wheel plate transport mode shown in Fig. 1, the 2nd limited block 24 is erected at by the groove
On optical axis 16.In addition, being also respectively equipped with a postive stop baffle 25 in the rear portion two sides of vehicle frame 10a, postive stop baffle 25 has front apron
It (is not marked in figure) with rear baffle, under four-wheel plate transport mode, for limiting the relative rotation of upright bar 12a and vehicle frame 10a.
In addition, though not showing in figure, a dismountable plate can also be installed on vehicle frame 10a, constitute entire support
Plane, in order to the lesser cargo of transportation volume.
The trolley of above structure can be deformed into Fig. 1-3 kinds of Transportation Models shown in Fig. 3.It is specific as follows:
1, four-wheel plate transport mode:
As shown in Figure 1, in this case, the 2nd limited block 24 is erected on optical axis 16, vehicle frame 10a is relative to upright bar 12a's
Position is locked by knob 15, and is limited by postive stop baffle 25.At this point, vehicle frame 10a is horizontally disposed, cargo is placed on vehicle frame
On 10a, push rod 12 is pushed, can be transported.
2, four turbine/lever transport mode:
Under four-wheel plate transport mode, knob 15 is unclamped, the rear portion of vehicle frame 10a is moved upward to conjunction along upright bar 12a
Right position is set, locking knob 15, forms four turbine/lever transport modes, as shown in Figure 2.
3, two turbine/lever transport mode:
Under four turbine/lever transport modes, knob 15 is unclamped, optical axis 16 is driven using the inertia of push rod itself and pushes open and determine
Position pin, enters optical axis 16 in the slot of the 1st limited block 20, realizes positioning.Crank 19 folds at this time, and two universal wheels are packed up, shape
At two turbine/levers transport mode shown in Fig. 3.
Under two turbine/lever transport modes, when needing to convert other modes, the 1st limited block switch knob 23 is pulled, is passed through
Brake cable pulls positioning pin 21, and positioning pin 21 rises, and is no longer formed and is limited to optical axis 16, pushes optical axis 16 at this time, disengages it from the 1st
Limited block 20 pulls back two universal wheels, that is, is convertible into other Transportation Models.
Furthermore it is also possible to install a removable hoistable platform 26 on vehicle frame 10a, the hoistable platform 26 is by plane four
Linkage and screw-drive mechanism composition.The screw-drive mechanism includes: two be removably mounted on the inside of vehicle frame 10a
Guide rod 27, the sliding block 28 being separately mounted on every guide rod 27, the batten 29 being erected on two sliding blocks 28 and a screw rod 30, it is 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 located at the rear portion vehicle frame 10a and connect with crank 31.
The four-bar linkage include a horizontal frame 32 and 4 piece support rod 33, every two support rods 33 be one group and
Middle part is hingedly in X-shaped, the left side both ends and right side both ends of the upper end difference support level frame 32 of two groups of support rods 33, two groups of branch
Two lower ends that strut 33 is located at Vehicular body front are removably mounted on vehicle frame 10a, solid positioned at two lower ends of rear vehicle
On batten 29.
Furthermore it is also possible to install support plate (not shown) on the horizontal frame, entire supporting surface is constituted, to transport
The cargo of defeated small volume.
By manual drive/rotation crank 31, batten 29 is pushed using screw-drive mechanism, and then drive four bar machine of plane
Structure is moved to right close to two fulcrums of rear vehicle, realizes the lifting of article carrying platform.
Vehicle frame 10a and hoistable platform 26 in the present invention can be made of aluminum profile, in the case where meeting intensity requirement,
The weight of entire car body can be mitigated.Turning for different transport modes is realized relative to the position of push rod 12 by changing vehicle frame 10a
It changes, to be suitable for the carrying of the cargo of different shape, weight.Hoistable platform 26 can be used for being promoted heavier cargo, mitigate manpower
Labour.Installation hoistable platform can be chosen whether according to different use requirements.
