Abstract

The utility model discloses a multifunctional carrying trolley for stairs. The multifunctional carrying trolley comprises a frame with four wheels, wherein the support is provided with a storage box, the rear end of the support is provided with push handles, and two rear wheels on the frame and the push handles are connected with the frame through telescopic mechanisms respectively. By adopting the lever principle, the telescopic mechanisms are arranged between the rear wheels and the frame as well as between the push handles and the frame respectively, and the rear wheels and the push handles are connected with the frame through the telescopic mechanisms respectively. When the multifunctional carrying trolley is in use, the length of the push handle can be reasonably changed according to the quantity of articles in the storage box, so that force used when the wheels are lifted is far smaller than the gravity of the articles in the storage box; the wheels are adopted for rolling, so that the friction force is reduced, and the pushing force is reduced, therefore physical strength is saved. The telescopic mechanisms are adopted for adjusting the rear wheels and the length of the push handles so as to achieve the effects of saving time and saving labor, and the adjustment for the rear wheels and the adjustment for the length of the push handles can be simultaneously carried out and can also be independently carried out.

Description

A kind of multifunctional stairway floor truck

Technical field

The utility model relates to a kind of multifunctional stairway floor truck.

Background technology

Ordinarily resident building, teaching building, office building etc. are not much all installed special cargo lift, bring a lot of difficulties and inconvenience, and amateur carrying personnel exist safety hazard in handling process to carrying thing on resident, clerical workforce etc. downstairs.Have at present the wheelchair patent of many energy stair activities both at home and abroad.But due to many-sided reasons such as economic, applicable, feasible or safety, there is not yet be in the market widely used can stair activity wheelchair or carry the chassis of wheelchair.

Utility model content

The purpose of this utility model is to address the above problem, and a kind of multifunctional stairway floor truck is provided, and this dolly, by regulating the length of trailing wheel to regulate the height of step, by using successively front and back wheel for the strong point, reaches the object that dolly moves up or down.

To achieve these goals, the technical scheme that the utility model adopts is: comprise the support with four wheels, be placed with storage tank on support; The rear end of support is provided with pushing hands; Two trailing wheels and pushing hands on described vehicle frame are connected with vehicle frame by telescoping mechanism respectively.

Four described wheels are cardan wheel.

Described telescoping mechanism be can be flexible elastic draw bar.

Compared with prior art, the utlity model has following beneficial effect:

The utility model adopts lever principle, by telescoping mechanism being installed between trailing wheel and pushing hands and vehicle frame, be connected with vehicle frame by telescoping mechanism respectively, in use can be according to the how many length that rationally changes pushing hands of the object in storage tank, the power using in lifting wheel is far smaller than the object gravity in storage tank; Adopt wheel to roll, reduced friction force and made thrust reduce saving muscle power.The utility model adopts telescoping mechanism to regulate the length of trailing wheel and pushing hands, reaches time saving and energy saving effect, can regulate also simultaneously and can regulate separately.

Accompanying drawing explanation

Fig. 1 is integral structure schematic diagram of the present utility model;

Fig. 2 is motion principle figure of the present utility model, the action schematic diagram that wherein Fig. 2-1 is the utility model front-wheel in the time going upstairs, and Fig. 2-2 are the action schematic diagram of the utility model trailing wheel in the time going upstairs.

Wherein, 1 is wheel; 2 is support; 3 is telescoping mechanism; 4 is pushing hands; 5 is storage tank.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1, the utility model comprises the support 2 with four wheels 1, and these four wheels are cardan wheel, are placed with storage tank 5 on support 2; The rear end of support 2 is provided with pushing hands 4; Two trailing wheels on described vehicle frame 2 and pushing hands 4 are connected with vehicle frame 2 by telescoping mechanism 3 respectively, in pushing hands 4 with two trailing wheels on telescoping mechanism 3 be can be flexible elastic draw bar.

As shown in Figure 1, trailing wheel of the present utility model can stretch, and adapts to the height of stair case step by changing the length of trailing wheel.Respectively there is one group of wheel in the front and back of dolly, to go upstairs as example, as shown in Fig. 2-1 and Fig. 2-2, take trailing wheel as the strong point, the height that front-wheel lifts a step moves forward the width of a step, front-wheel arrives and steps to a new level, then take front-wheel as the strong point, the height that trailing wheel lifts a step moves forward the width of a step, trailing wheel arrives and steps to a new level, dolly has just upwards been walked a step like this, goes round and begins again like this, repeats identical action dolly and just can go on stair; Otherwise, as the same.What dolly adopted is lever principle, the point of application can according to carrying number regulate, by changing the length of pushing hands.Except stair carrying, can also serve as hand-cart for shopping, save the trouble of handbag, save muscle power.Time on the shelf, can be placed on family as a storage tank, rationally utilize family space.Multifunctional stairway floor truck does not adopt any engine installation, and reaches the effect of environmental protection, can in using, reach the effect of taking exercises yet.
