Problems solved by technology

But its disadvantage is that since the four wheels alternately rise or fall, the intermittent collapse is strong, so it will always bring an uncomfortable bouncing feeling. In addition, the structural strength of the connecting shaft and connecting rod required is large. And the four wheels take up too much space,

Embodiment Construction

[0017] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0018] As shown in Fig. 1 and Fig. 2, the flat ground and stair-climbing dual-purpose vehicle of the present invention comprises a vehicle frame 1, a handrail 4, an axle 10 installed under the vehicle frame 1 and a wheel 5 mounted on the axle 10, and is characterized in that The wheels 5 described above are three-circle curved-edge smooth conjoined, and each wheel 5 is respectively installed on its own axle 10, and is connected with the axle 10 in a rolling manner. Intermediate wheel 6, this fan-shaped intermediate wheel 6 is slidingly fitted with axle shaft 10. The outer edge of the curved-edge smooth-jointed three-circle wheel 5 is composed of three convex arcs and three concave arcs, and the radian of the concave arcs is 110-130°. Generally, the specific radian of the concave arc can be determined according to the step spacing of the s...

Abstract

The present invention relates to civil machinery, and is especially one kind of two-purpose ground and stairs handcart. The two-purpose handcart includes frame, handle, shaft and wheels, and features its wheels with perimeter comprising three circles contained smoothly and connected with shafts in rolling mode, and the sector idle pulleys fitted with shafts in sliding mode. The two-purpose handcart has its wheels well matched with stairs for running in stairs smoothly, safely and easily.

Description

Technical field: [0001] The invention belongs to civil machinery, in particular to a dual-purpose vehicle suitable for level ground and climbing stairs. Background technique: [0002] With the development of the economy, high-rise buildings continue to increase, and there are no elevators in general residential buildings. It is inconvenient for the disabled and the elderly with limited mobility to go up and down the stairs. For this type of problem, people have developed a variety of stair climbing vehicles, generally using multiple sets of wheels and connecting them to the center wheel through connecting rods and shafts, such as using four ordinary round wheels. Falling on the second step, the distance between the wheels is just the height of the first step and the second step, so it is easier to go up and down the stairs. But its disadvantage is that since the four wheels alternately rise or fall, the intermittent collapse is strong, so it will always bring an uncomfortab...
