Description

Bamboo-made cart with two wheels

The utility model belongs to the improvement of two-wheel flatcar, and it is a kind of People-Powered Vehicle.

At present, normally used two-wheel flatcar adopts iron wood structure, and the rubber tire is housed, and pneumatic tyre inflation back is flexible, and is laborsaving during rolling.But this class two-wheel flatcar structure heaviness has relatively reduced transportation volume, and when empty wagons was parked, it was big to take up space, and moves inconvenience.

The utility model is the improvement to existing two-wheel flatcar, and the mao bamboon of having adopted mountain area, China south to abound with is a material, has saved a large amount of iron, wood material, has alleviated the vehicle body deadweight.At wheel hub inner edge ball bearing of main shaft is housed, has reduced friction, light laborsaving.The wheel damping spring also is housed simultaneously, can be shockproof.Driving steadily.In the both sides of vehicle body a movable back and movable supporting feet are housed respectively.Enlarge the purposes of two-wheel flatcar, particularly linked up the town and country transportation, be engaged in the comparatively practicality of Sole Proprietorship specialist.

Accompanying drawing is the scheme drawing of a bamboo flatcar of two-wheel: among the figure (1) be the car thick stick (with handlebar be whole garden mao bamboon), (2) be the vehicle body paving, (3) be the vehicle body crosspiece, (4) be wheel, (5) regulate fix screw for movable back, and (6) are kinematic support, (7) be movable back, (8) be the car pin, (9) are the wheel damping spring, and (10) are cushion block, (11) for the wood card arc of wheel hub is installed, (12) be movable brace rod, (13) are movable supporting feet, and (14) are wheel hub iron hoop, (15) be the wheel hub, (16) be ball bearing of main shaft, (17) are wheel hub, and (18) (19) are mortise on wheel hub and the wheel rim, (20) be wheel rim, (21) be wheel spoke, (22) are wheel rim anticracking bolt, and (23) are wheel rim outer rim hard rubber tire.

Vehicle body of the present utility model, wheel and damping spring are that material is made with mao bamboon all. The car thick stick is to make with whole garden tubular mao bamboon, and its end that stretches out vehicle body is handlebar. To link with tenon between vehicle body crosspiece and the car thick stick. At vehicle body crosspiece upper berth one deck bamboo chip, fixedly become the vehicle body paving with screw (or rivet) and crosspiece. When the device vehicle body,, at car thick stick and whippletree joint, also must reinforce with angle bar, to guarantee bus body strength all with pin or screw and binder-reinforced at the tenon seam crossing.

Wheel is made up of hub, spoke and wheel rim etc.The wheel hub is bonded into an integral body with adhesives after by the assembly unit of mao bamboon piece, and its two ends hoop is gone up iron ring and reinforced, and at its two ends inwall ball bearing of main shaft is housed.Wheel rim is bent by the mao bamboon circle and is bonded.The wheel that the vehicle wheel footpath is less, its wheel rim can enclose with one deck mao bamboon.The seam of mao bamboon circle is with little bitch and adhesive, at wheel rim outer rim bag one deck hard rubber tire.The seam of the hard rubber tire of wheel rim and outsourcing should misplace when the assembling wheels wheel rim, to guarantee the intensity of wheel rim.Dig 16 mortises at branches such as hub outer rims, the mortise position is to misplace at interval in hub center line both sides.Dig 16 mortises at the same five equilibrium of wheel rim inwall midline position.Looking its mortise of wheel diameter size can suitably increase and decrease.Wheel spoke adopts the mao bamboon split block of 10～15 millimeters thick to make the big trapezoidal type shape in little bottom, top, and two to share adhesive bond, and uses a screw retention at the middle part.If the less wheel in a wheel footpath then available mao bamboon split block is done spoke.The tenon at spoke two ends is respectively charged in the mortise of hub and wheel rim, makes hub and wheel rim tensioner.When assembling wheels, all seams are all reinforced with adhesive bond.Produce cross break at the mortise place in order to prevent that the spoke tenon from packing into behind the wheel rim mortise, near the wheel rim middle part each mortise penetrates an anticracking bolt, and the both sides pad is tightened reinforcing with packing ring.In vehicle body Che Gang bottom damping spring is housed.Damping spring is to be fixed into one with the folded back of making of mao bamboon split block that successive increases with overbolt.Fix a wood card arc that wheel hub is installed in the damping spring lower end.Wheel hub is made by a metal bar material, is installed in the wood card arc hole of damping spring bottom, and wheel is loaded onto at two ends.

The utility model is at the movable back of vehicle body one end device near handlebar, and movable back is connected with movable pin with vehicle body car thick stick, can center on movable pin and rotate along A, B, C direction.Movable supporting feet is equipped with in both sides at the other end of vehicle body, and a crosspiece is housed between the movable supporting feet.Movable supporting feet and vehicle body car thick stick are to link with movable pin, can rotate along D, E, F.Movable back and movable supporting feet all insert in their adjustment hole with the adjusting bolt on the kinematic support of side when adjusting position, tighten fly nut and fix it.

The utility model is compared with existing two-wheel flatcar, its advantage is: utilize mao bamboon as the material of making vehicle body, wheel, damping spring, saved iron and steel and timber, alleviated the deadweight of vehicle body, when empty wagons is parked, be easy to vehicle body is erect arrangement or resettlement position.Ball bearing of main shaft is installed, between vehicle body and wheel shaft, damping spring has been installed at the hub inner edge, so car is light in transportation, shockproof, steady.Before and after vehicle body, movable back and movable supporting feet are housed, have enlarged the purposes of two-wheel flatcar.When the position of movable back at A, can be used as the vehicle body sideboard, when its position at B, the chaise longue when can be used as rest; When its position at C, vehicle body is plugged the account bar for four jiaos, hangs up bed-curtain, then can be used as just bed of field or family expenses.The effect of movable supporting feet is, when its position at D, can be used as the vehicle body spike, supports vehicle body when stopping, and makes the vehicle body held stationary; When its position at E, can be used as interim first-aid patients and the stretcher of road can not drive a vehicle the time, front and back two people lift and walk it; When its position, can be used as the shelves frame of goods at F.So the utility model can play outside the transportation function of general two-wheel flatcar, but also double as multiple use, comparatively practicality.
