Description
Technical field
The utility model is related to hand buggy technical field, particularly a kind of type foldable cart with anti-canting function.
Background technology
Hand buggy is widely used in factory or for ordinary populace, at present, the folding stair climbing used is pulled as loading toolses
Car can climb building runner using triangle, and each three castor is inlayed by three steamboats being distributed with even circumferential with an A-frame
Form, during going upstairs, three castors climb building effect because that can be rotated by external force effect around axletree so as to reach, but such small
Functionally there is certain shortcoming in car, may be small during building is climbed in the case where the goods of drawing is relatively more and heavy
Car triggers three castors to reverse because rear is overweight, causes people's disequilibrium and falls down, therefore, and invention is a kind of, and there is anti-canting function to climb
Building type foldable cart seems very necessary.
The content of the invention
The purpose of this utility model is to solve the above problems, devise a kind of folding with anti-canting function and pull
Car.
Realize that above-mentioned purpose technical solutions of the utility model are, a kind of anti-canting climbs building type foldable cart, including handle, in
Between bar, side lever, connecting rod, main shaft, sleeve, climb the horn ring of building three, zone circle screw, ratchet, ratchet, extension spring, hinge, rear car
Wheel, the Wheel shaft two ends are equipped with ratchet, and ratchet end face is fitted with climbing on the outside of building triangle wheel support, and bullet will be stretched during stair climbing
Spring is hung on support on corresponding zone circle screw, forces ratchet to be contacted with ratchet in the presence of spring force, due to ratchet peace
On main shaft, then main shaft will not take a turn for the worse, and can only produce one-way movement, when the bidirectional-movement for wanting to realize main shaft, can be by
Extension spring one end is hung on another corresponding zone circle screw, in the presence of spring force so that ratchet departs from ratchet;
Described connecting rod is connected with intermediate bar and side lever by bearing pin, and upper intermediate bar is connected with upper bar by upper connecting rod, it is lower in
Between bar be connected with lower lateral rods by lower connecting rod, upper sleeve is arranged on main shaft, and upper sleeve and lower sleeve portion pass through hinge
Connection, up and down side lever be respectively fitted over above and below in sleeve.
Described climb on the horn ring outrigger of building three respectively has two zone circle screws and a ratchet.
The pawl side has zone circle screw, and extension spring one end is hung on the zone circle screw on ratchet.
There is hole at the connecting rod two ends, are easy to be connected by bearing pin with intermediate bar and side lever.
There is corresponding space the side lever side, is easy to intermediate bar to be retracted in side lever.

Embodiment
The utility model is specifically described below in conjunction with the accompanying drawings, as shown in Figure 1, Figure 4 and Figure 5, anti-rollover climbs building folding
Folded hand buggy, including upper intermediate bar 2, upper bar 3, upper connecting rod 41, the upper connecting rod 41 pass through bearing pin 101 and upper intermediate bar
2 are connected with upper bar 3, and upper connecting rod 41 can be retracted in intermediate bar 2;Similarly, the lower connecting rod 42 is also by bearing pin
102 are connected with lower intermediate bar 18 and lower lateral rods 16, and lower connecting rod 42 can be retracted in lower intermediate bar 18;Two upper bar 3
Corresponding two upper cartridge 6 is inserted, two lower lateral rods 16 insert corresponding two lower cartridge 15, and side lever can be stretched in sleeve up and down
Contracting, upper cartridge 6, the structure chart of lower cartridge 15 are respectively referring to Fig. 6, Fig. 7.
There are two zone circle screws on the ratchet structure schematic diagram climbed described in as shown in Figure 8 on building triangle wheel support 8, support 8
91st, 93 and a ratchet 11, there is a zone circle screw 92 on the ratchet 11, one end of extension spring 13 hangs over zone circle screw 92
On, when the other end of extension spring 13 is hung on zone circle screw 91, ratchet 11 departs from ratchet 10, when extension spring 13 hangs over ratchet
On zone circle screw 93 on when, ratchet 11 is contacted with ratchet 10;The two ends of Wheel shaft 5 are equipped with ratchet 10, the end face of ratchet 10
Fitted with climbing the outside of building triangle wheel support 8, extension spring 13 is hung over to the zone circle screw 93 on support, in spring bullet during stair climbing
Ratchet 11 is forced to be contacted with ratchet 10 in the presence of power, because ratchet 10 is arranged on main shaft, then lathe main shaft 5 will not occur inverse
Turn, single direction rotation can only be produced, when level land motion wants to realize the bidirectional rotation of main shaft 5, extension spring 13 can be hung over zone circle
On screw 91, in the presence of spring force so that ratchet 11 departs from ratchet 10.
The utility model fold when such as Fig. 2 and Fig. 3, when folding vertically, both hands can be held to upper bar 3 and received obliquely
Contracting, upper connecting rod 41 is retracted in upper bar 3, due to the interlink function of bar, the downward intermediate bar 18 of lower lateral rods 16 of car is drawn close, under
Connecting rod 42 is retracted in lower lateral rods 16 simultaneously, and the rotation of hinge 14 can be by the top of vehicle body and lower folded.
The technology contents do not addressed in aforesaid way are taken or used for reference prior art and can be achieved.
