Description
(1). technical field
The utility model belongs to the transportation means field, particularly a kind of hand barrow that is used to transport.
(2). background technology
Usually the less goods of transportation volume often adopts the hand barrow carrying.At present the hand barrow that uses can not upper and lower step, and obstacle detouring hinders and crosses ditch, and carries for a short time, and load can not withstand shocks.
(3). technology contents
The purpose of this utility model provides a kind of hand barrow.The upper and lower step of its energy, obstacle detouring hinder and cross irrigation canals and ditches, and carrying is big, the load that can withstand shocks, and structure is small and exquisite, rotates flexibly.
For reaching above-mentioned purpose, the utility model is separately installed with front-wheel and trailing wheel in the bottom of vehicle frame, and trailing wheel adopts cardan wheel, and front-wheel is installed in the two side holes of front wheel carrier.The afterbody of vehicle frame is equipped with push rod, and front axle is installed in the bottom of vehicle frame with orienting sleeve, damping spring, bolt, and front wheel carrier is connected with front axle with pad with bolt, the formation hinge.Conversion block is connected with two side plates of vehicle frame with axle sleeve with bolt; The two ends of lower link are connected with hinge with conversion block with front wheel carrier respectively.Handlebar connects to ground; The two ends of boxed rod are connected with hinge with handlebar with conversion block respectively.The boxed rod bottom is connected with pipe box, and boxed rod is vertical mutually with pipe box, and described pipe box is enclosed within the pipe link.Pipe link and conversion block bolt together.
Change down handlebar into array structure: the two ends of contiguous block are connected with pedal with vehicle frame respectively, and connecting rod is connected with the contiguous block middle part with conversion block respectively; Contiguous block ' respectively and vehicle frame and pedal ' be connected, connecting rod ' respectively and conversion block and contiguous block ' be connected, promptly form the pedal hand barrow.
The utility model is because therefore the shock absorption device of front axle being installed on vehicle frame and being made up of orienting sleeve and damping spring can cushion various impact loads, and carrying is big.Front-wheel is connected with front wheel carrier, and the rich front-wheel in front-wheel axle center rotates, and realizes the shift in position of front-wheel, make this hand barrow can upper and lower step, obstacle detouring hinders and cross ditch; The leverage that utilizes upper and lower connecting rod, conversion block and handlebar to form, laborsaving when making the upper and lower step of this hand barrow, obstacle and crossing irrigation canals and ditches.The utility model also has structure small and exquisite, rotates flexibly, is adapted at the characteristics of narrow space shipping goods.
Below in conjunction with accompanying drawing the utility model is described further.

(5). the specific embodiment
Referring to Fig. 1 and Fig. 2, be example with single handlebar trolley structure.Base plate and push rod 11 are installed on vehicle frame 7, and universal rubber trailing wheel 2 bolt togethers are on vehicle frame 7, and universal rubber trailing wheel 2 can be done 360 ° turning to.Front axle 10 usefulness bolts, orienting sleeve and damping spring are connected with vehicle frame 7, be used to cushion various impact loads, front wheel carrier 6 usefulness bolts are connected with front axle 10 with pad, and its front axle 10 of having mercy on is rotated flexibly, front-wheel 8 usefulness axle sleeves and bolt are installed in the hole of front wheel carrier 6 both sides, and front-wheel 8 can be rotated in the hole of front wheel carrier 6.Conversion block 3 usefulness axle sleeves are connected with the both sides of bolt with vehicle frame 7, form hinge.Handlebar 1 is connected with vehicle frame 7 usefulness hinges; The two ends of lower link 5 are connected with conversion block 3 with front wheel carrier 6 respectively, and the two ends of boxed rod 2 are connected with conversion block 3 with handlebar 1 respectively.Boxed rod 2 bottoms are connected with pipe box, its boxed rod 2 and pipe box be " T " font of vertical formation mutually, and described pipe box is enclosed within the pipe link 9, and pipe link 9 is done a spot of end float misalignment relatively, tension and compression load with balance control handle 1 is consistent front wheel carrier 6 leaning angles.
Referring to Fig. 8-Figure 11.When needs are pushed to step with hand barrow, handlebar 1 is drawn to push rod 11 directions, handlebar 1 drives upper and lower connecting rod, conversion block 3 drives front wheel carrier 6, and front wheel carrier 6 rich front axles 10 rotate and make front-wheel 8 translation-angles.The maximum inclination angle of front wheel carrier 6 is 70 ° and 30 °.When the angle of inclination of front wheel carrier 6 is 70 °, after a pair of front-wheel 8 touches step surface, handlebar 1 is pressed to push rod 11 reversing senses, front-wheel 8 rolls up step, handlebar 1 is continued to press to push rod 11 reversing senses, make boxed rod 2 cross dead center position and self-locking, both hands are held push rod 11, have pushed to step even trailing wheel 4 is mentioned hand barrow.Same operation can make this hand barrow get out of a predicament or an embarrassing situation and clear the jumps and gets over the irrigation canals and ditches of certain width.
Referring to Fig. 6 and Fig. 7.Change handlebar 1 into two, two boxed rod 2 bottoms all are connected with pipe box, and its boxed rod 2 and pipe box be " T " font of vertical formations mutually, and described pipe box is enclosed within the two ends of pipe link 9, and composition pair handlebar hand barrows reach above-mentioned same effect equally.
Referring to Fig. 5.The installation direction of handlebar 1 and boxed rod 2 is opposite with boxed rod 2 installation directions with the handlebar 1 shown in Fig. 1, form reversible control handle hand barrow, reach above-mentioned same effect equally.
Referring to Fig. 3 and Fig. 4.Change down handlebar 1 into array structure: the two ends of contiguous block 12 are connected with pedal 14 with vehicle frame 7 respectively, and connecting rod 13 is connected with contiguous block 12 middle parts with conversion block 3 respectively; Contiguous block 12 ' respectively and vehicle frame 7 and pedal 14 ' be connected, connecting rod 13 ' respectively and conversion block 3 and contiguous block 12 ' be connected, promptly form the pedal hand barrow.When needs are pushed to step with hand barrow, with right crus of diaphragm step on pedal 14 ', rotate in the hinge axle center on contiguous block 12 ' rich vehicle frame 7, drivening rod 13 ' pulling conversion block 3 rotations; After a pair of front-wheel 8 touches step surface, step on pedal 14 with left foot again, rotate in the hinge axle center on the contiguous block 12 rich vehicle frames 7, and drivening rod 13 presses down conversion block 3 is rotated, and makes front-wheel 8 roll up step.Both hands are held push rod 11, have pushed to step even trailing wheel 4 is mentioned hand barrow.
This hand barrow is set to 4 with front-wheel 8, can carry bigger load, owing on the front axle 10 shock absorption device is installed, makes general impact load little to the influence of this hand barrow.
