Description

MPV multipurpose vehicle that can stair activity

The utility model relate to can on level land, road, use in a kind of family daily life again can stair activity MPV multipurpose vehicle.

At present; the car that uses in the family daily life is only limited on level land, the road and uses; for resident in the building, particularly do not have a resident in the building of elevator; when needs upstairs, downstairs when transport disease (always) people, baby and article; can only be by manually shouldering, lifting; not only require great effort but also dangerous, therefore, bring a lot of difficulties for these residents through regular meeting.

The purpose of this utility model: design and provide a kind of and not only can when walking also can be at stair activity on the level land, can walk freely in the same old way, MPV multipurpose vehicle that steadily failure-free can stair activity, reach upstairs, downstairs when transport disease (always) people, baby and article, time saving and energy saving, safe and reliable, as to reduce high building resident difficulty purpose.

Structure design of the present utility model: MPV multipurpose vehicle that can stair activity is made of vehicle frame, handlebar, preceding bull wheel, back steamboat, back vent, tight pulley shoe, operating handle, link rod, lever and fulcrum; Down either side is equipped with preceding bull wheel before the vehicle frame, and Aft cross member connects with the back vent upper end is movable, and the back vent lower end is equipped with the back steamboat; Connect with rotating in the middle of the vehicle frame entablatrance in the middle of the operating handle, biconditional operation handle inner end, link rod upper end is rotated and is connected, the link rod lower end is rotated with the lever upper end and is connected, the lever middle part connects with the fulcrum of vehicle frame cross sill is movable, and the lever lower end connects with the back steamboat crossbeam that is actively connected on the back vent below is movable; Respectively be equipped with on the oblique frame of vehicle frame both sides and its eight, in line, can form tight pulley along the steamboat that stair roll and carry out.

Advantage of the present utility model, characteristics and good effect:

1, rational in infrastructure, volume is little, simple to operate flexible, easy to use;

2, the back steamboat can put down and can pack up, and both can use on level land and road, can use when stair activity again, and people on the car and thing are not subjected to the influence because of the angle variation;

3, the wide model of purposes can be used to upstairs, transport disease (always) people, baby and article downstairs, an especially big furniture or articles for use;

4, time saving and energy saving in the use, steadily, safely, reliably, reduced high building resident's difficulty;

Fig. 4: back view of the present utility model during level walking;

Among the figure: 1 vehicle frame, 2 handlebars, 3 preceding bull wheels, 4 back steamboats, 5 back vents, 6 tight pulleys are carried out, 7 operating handles, 8 link rods, 9 levers, 10 fulcrums, 11 vehicle frame entablatrances, 12 vehicle frame cross sills, 13 back steamboat crossbeams, 14 steamboats, 15 Aft cross members.

Most preferred embodiment:

MPV multipurpose vehicle that can stair activity is made of vehicle frame, handlebar, preceding bull wheel, back steamboat, back vent, tight pulley shoe, operating handle, link rod, lever and fulcrum; Down either side is equipped with preceding bull wheel before the vehicle frame, and Aft cross member connects with the back vent upper end is movable, and the back vent lower end is equipped with the back steamboat; Connect with rotating in the middle of the vehicle frame entablatrance in the middle of the operating handle, biconditional operation handle inner end, link rod upper end is rotated and is connected, the link rod lower end is rotated with the lever upper end and is connected, the lever middle part connects with the fulcrum of vehicle frame cross sill is movable, and the lever lower end connects with the back steamboat crossbeam that is actively connected on the back vent below is movable; Respectively be equipped with on the oblique frame of vehicle frame both sides and its eight, in line, can form tight pulley along the steamboat that stair roll and carry out.

When walking on level land and road, depress operating handle, link rod is lifted, and lever puts down the back steamboat under the effect of fulcrum, at this moment, MPV multipurpose vehicle that can stair activity can the level land and road on used.

When stair activity, lift operating handle, link rod is depressed, lever is regained the back steamboat under the effect of fulcrum, at this moment, steamboat on tight pulley is carried out gets final product on comprehensive inclined-plane attached to stair with the preceding bull wheel that is positioned on the preceding down either side of vehicle frame, pulls a cart just can walking up and down freely on the stair inclined-plane by pulsation-free, and people above the car or thing then are not subjected to the influence of angle variation.
