Description
But hand barrow is the hand barrow of two a plurality of delivery wheels of axletree band of stair activity, and star-like wheel is equipped with at the axletree two ends, is mainly used in carrying people of family or thing.
The high-mobility, multipurpose, wheeled vehicle stair level land dual-purpose barrow of Chinese utility application specification sheets CN2043202U number record on August 23rd, 1989 is by vehicle frame (comprising handlebar), vehicle frame lower end bonded assembly axletree, the axletree two end axles is connecting star-like wheel and guide wheel is formed.The track adjusting wheel of this hand barrow is to be contained in the leg lower end of stretching under the hand barrow front end.Track adjusting wheel always is in the lower end and influences the convenience of going downstairs on the hand barrow.Star-like of star-like felly is equipped with the common uni-directional brake of forming of slipper, equalizing pipe and balance ball.The effect of one-way brake is unreliable.
The purpose of this utility model is to provide stair activity more convenient failure-free hand barrow.
Hand barrow of the present utility model contains the star-like wheel that vehicle frame, vehicle frame lower end bonded assembly axletree, axletree two end axles are connecting.Its constructional feature is that the vehicle frame lower end is connected with the pole of protracting and can descending folding, and the pole front end is equipped with wheel.When the level land, can roll over pole down, wheel is landed, keep the steady of vehicle frame, and can steadily stand in ground.Can turn back pole when last going downstairs, make wheel be lifted away from ground, prevent wheel collision stair, stair activity is more convenient.When hand barrow was gone downstairs, each wheel of star-like wheel was braked and does not change, and star-like of the star-like vehicle wheel rim outside groove was housed, and groove is inserted with backing block.Promote backing block, the backing block front end is contacted with star-like vehicle wheel rim, end the truck wheel and rotate, it is reliable to end card, guarantees when hand barrow is gone downstairs steady.When or upstairs on the level land, backing block is retracted, leave vehicle wheel rim, wheel is freely rotated.Vehicle frame protracts and can descend the pole of folding, and the most handy rivet connects between two sections of folding mutually, is connected with hook between two sections.After rolling over down,, keep the wheel of pole lower end to land with hooking.Open hook,, can keep the wheel lift of pole lower end again with hooking rolling on the hypomere.
Hand barrow of the present utility model is compared with existing hand barrow, and the supporting wheel that protracts is convenient to lift, and can not collide stair, and the chocking construction of star-like wheel is also more convenient reliable, makes stair activity more convenient reliable.
Accompanying drawing has been represented the scheme drawing of a kind of hand barrow of the present utility model.
Further specify the utility model hand barrow below in conjunction with the accompanying drawing example.This hand barrow is made up of folding vehicle frame 1, axletree 2, star-like wheel 3, front support rod wheel 4.Vehicle frame has the handlebar of tiltedly stretching 5, and has hung a pocket 6.The axletree 2 that flat traverse is put is being welded in the vehicle frame lower end.Axletree two ends running-fit cover is followed star-like 7 of star-like wheel.Star-like three poles that are even cloth, running-fit is being adorned wheel 8 before each pole.Locate to be equipped with protruding rectangular channel 9 for star-like outside each wheel 8 edge, groove is inserted with rubber backing block 10, and rubber backing block 10 front ends are relative with wheel 8 edge.The current backing block 10 that pushes away, the backing block front end is stuck in wheel 8 edge, and wheel 8 is checked.Welding a pole 11 of protracting and descending to roll in vehicle frame 1 lower end, pole front end running-fit is equipped with wheel 12, pole 11 is divided into two sections of front and back, be connected with a rivet 17 between leading portion 13 and the back segment 14, the pole that formation can be rolled over up and down, hook 15 also is housed between two sections, and the folding back tangles with hook 15 instantly, makes preceding wheel 12 keep landing.Pole back segment riveted joint place upside has catch 16, the pole leading portion is lifted to stopped when straight.Preceding straight wheel can play the guiding role, and during downstairs through platform, car turns forward last, and a wheel lands before making, and is convenient to turn.
