A kind of changeable wheelbase damping type hand buggy, comprise variable handrail, fastening adjustment spanner, propons, damping Universal wheel, baffle plate, scalable vehicle frame, back axle, be characterized in: variable handrail is comprised of upper and lower grab rail, between upper and lower grab rail, by the chute adjustment height on upper and lower grab rail, connect, and fastening by a pair of adjustment spanner; Lower grab rail lower end and propons are rotationally connected; Scalable vehicle frame is comprised of forward and backward chute track, between forward and backward chute track, coordinate flexible connection, and by bolted, forward and backward chute track is connected with forward and backward vehicle bridge respectively by four pairs of binding bolts, form vehicle body whole, four damping Universal wheels are housed respectively below forward and backward vehicle bridge.

Forward and backward vehicle bridge is provided with four pairs and connects the bolt hole that forward and backward chute track forms five kinds of different bodys width.

Above scalable vehicle frame, corner location is provided with four fixedly baffle plates of goods-container.

Damping Universal wheel 4 comprises three individual event thrust ball bearings, wheel, steel spring, vehicle wheel rotation plate, wheel mount, wheel both sides are connected with vehicle wheel rotation plate by steel spring respectively, individual event thrust ball bearing is equipped with in wheel and steel spring junction, an individual event thrust ball bearing is equipped with in vehicle wheel rotation plate and wheel mount junction, and diaphragm spring is equipped with in the junction of wheel mount and propons.

Handrail upper end is provided with handle, and handle jacket has the hand gum cover of being made by PU material.

The beneficial effects of the utility model are:

The scalability of handrail can meet different height users' needs, has increased applicable crowd; The variable demand that makes can meet different measurement of cargo sizes when lade of size of front and back vehicle bridge and left and right vehicle frame; Unique damping Universal wheel device adds the shock-absorbing function of diaphragm spring, make unit body can alleviate the vibration being produced by uneven road surface in transportation, the infringement of reduction to lade, has strengthened the crossing ability of vehicle body, has extended service life greatly.In addition the parts of whole changeable wheelbase damping type hand buggy adopt corrosion-resistant steel casting to form, and have improved the delelivered payload capability of vehicle body.Such structure design makes that this hand buggy is detachable, easily assembling, collapsible, storage institute take up space little.This utility model is broken away from the situation of traditional hand buggy simple function, and the diversification of practical function, the demand such as convenient are applicable under most of conditions on a small quantity, the interim transportation on a large scale, and Applicable scope is greatly improved.
