Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figs 1-4, the trolley of a kind of mechanical gear transmission, including vehicle frame 1, rear-wheel 2, front-wheel 3, axle 4, handle 5,
Worm screw 7 and worm gear 8, wherein rear-wheel 2 and front-wheel 3 are two, are mounted side by side in the two sides of vehicle frame 1, axle 4 passes through vehicle frame 1
It is fixedly connected, can be rotated with the rotation of front-wheel 3 with the center of two front-wheels 3；Handle 5 and worm screw 7 are installed on vehicle frame 1, hand
Handle 5 is connected with worm screw 7, and worm screw 7 can rotate with the rotation of handle 5；Worm gear 8 is installed on axle 4, can be turned with axle 4
It moves and rotates, and worm gear 8 is meshed with worm screw 7, worm screw 7 can push worm gear 8 that axle 4 is driven to rotate when rotating, to realize
The walking of trolley.
Further, it is connected between the handle 5 and worm screw 7 by bevel gear set 6.
Further, the bevel gear set 6 is to intersect vertically, and the radial direction that the lateral rotation of handle 5 is converted into worm screw 7 is turned
It is dynamic.
Further, the axle 4 is connected by key with worm gear 8 is connected as one.
Further, it is also connected with a synchronizing shaft among described two rear-wheels 2, guarantees that two rear-wheels 2 rotate synchronously.
Further, the worm gear 8 is placed on axle 4, and axle 4 is equipped with the combined cover with axle 4 with key connection, knot
The adjacent face of trap and worm gear 8 has intermeshing tooth, worm gear 8 can be made to be combined or be taken off with axle 4 by stirring combined cover
It opens.
Further, the vehicle frame 1 is tower structure.
