Abstract

The utility model relates to a multifunction handcart with going and descending upstairs and walking on land. A wheel rib 9 is hinged with a back frame 4, the wheel rib 9 is hinged with two sets of rubber wheels 10, and a beta angle is formed between the two sets of the rubber wheels. The utility model has the advantages of small impact force of going and descending upstairs, labor saving and portable use, and can be used as a chair. The utility model is particularly suitable for carrying goods going and descending upstairs of people living in high buildings and can be used on flat land.

Description

Go up the multi-functional light roadster that pulls in level land downstairs

The utility model relates to a kind of multi-functional light roadster that pulls in level land downstairs of going up that is used for the roping goods.

Chinese patent disclosed and pulled light roadster downstairs on several, and the common ground of this type of car is only to be evenly equipped with one group of rubber tire on spoke, though can go up downstairs, but owing to have only one group of uniform rubber tire, produce bigger impulsive force when last going downstairs, noise is bigger during use, influences other people and has a rest.

It is little that the purpose of this utility model just provides a kind of impact shock of upward going downstairs, and uses the light multi-functional light roadster that pulls in level land downstairs of going up.

Solution of the present utility model is such: with after-frame 4 pivotally attached spokes 9 radiuses be φ ₁On be distributed on several rubber tires, be φ at radius ₂On be evenly equipped with several rubber tires, the β angle of staggering between two groups of rubber tires, two groups of rubber tires can be adapted with stairway width S, height h when rotating well, rely on buffering and supporting role between the steamboat, dolly can be gone up downstairs more reposefully, reduce impact shock, and it is more laborsaving, when on the level land, walking, walk on the ground by two adjacent in train steamboats, steadily reliable.

The utility model has the advantages that downstairs impact little, laborsaving, use light.

Accompanying drawing is embodiment of the present utility model:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is pulling structural representations.

Accompanying drawing 3 is rolling scheme drawings when going up downstairs.

The utility model includes feet 1, strut bar 2, underframe 3, after-frame 4, lengthening bar 5, two sleeve 6, adjustable sleeve 7, connecting strap 8, spoke 9, rubber tire 10.

Spoke 9 is hinged with after-frame 4, radius φ on the spoke 9 ₁Be evenly distributed in several rubber tires 10, at radius φ ₂Be evenly equipped with the β angle of staggering between 10, two groups of rubber tires of several rubber tires on the circumference.Underframe 3 is socketed on the after-frame 4 by adjustable sleeve 7, and an end and the strut bar 2 of underframe 3 are hinged, also are hinged with feet 1 on underframe 3.Lengthening bar 5 is socketed on the after-frame 4 by two sleeves 6.

Principle of work of the present utility model is: structure shown in the accompanying drawing 1 is a standing state, at this moment, can place weight or be used as the chair use.When drawing weight, recoverable feet 1, stir strut bar 2, underframe 3 is recovered to state shown in the accompanying drawing 2, center of gravity reduces and just can spur weight and walk.Lengthening bar 5 is elongated, make go downstairs more laborsaving, in the present embodiment, at radius φ ₁Uniform three rubber tires 10 on the circumference are at φ ₂The β angle of staggering between 10, two groups of rubber tires of uniform three rubber tires on the circumference, β angle make when going up downstairs φ in ℃ scope of 0＜β＜60 ₂On rubber tire just with stair height h fit.

When going downstairs in the pulling, spoke 9 rotates, and rubber tire 10 contacts with underground in turn, just weight can be pulled on the building, because φ ₂Gluing wheel just with stair height h fit, it is minimum that impact shock can reduce to.

Time spent not at ordinary times, but shown in the harvest accompanying drawing 2, lengthening bar 5 is regained, can reduce collection space.
