Abstract

The invention relates to a draw-bar box, which comprises a box body, a draw bar, rolling wheels and support feet, wherein the rolling wheels are positioned at the bottom of the box body; the support feet are in telescopic arrangement in the self height direction; the draw bar box also comprises a horizontal detection instrument and a control mechanism; the horizontal detection instrument is arranged on the top of the box body; the control mechanism can receive detection information of the horizontal detection instrument and can automatically regulate the support feet to achieve the telescopic effect so that the box body can be horizontally placed. The draw-bar box has the advantages that by arranging the horizontal detection instrument and the control mechanism, the height of the support feet can be automatically regulated, so that the draw-bar box can be stably placed on any plane; meanwhile, the structure is simple; the implementation is convenient; the cost is low.

Description

A kind of draw-bar box

Technical field

The present invention relates to a kind of draw-bar box.

Background technology

Draw-bar box very common in life, general draw-bar box includes casing, pull bar, the roller being positioned at box bottom and a spike, and the bottom surface of the bottom surface and roller of wherein propping up spike flushes setting such that it is able to realize the placement of casing.

But, when ground is not at level, cause the inclination of casing, therefore, center of gravity just there occurs skew, causes casing smoothly to place.

Summary of the invention

The technical problem to be solved is to overcome the deficiencies in the prior art, it is provided that the draw-bar box of a kind of improvement.

For solving above-mentioned technical problem, the technical scheme that the present invention takes is as follows:

A kind of draw-bar box, it includes casing, pull bar, the roller being positioned at box bottom and a spike, this spike can stretch along oneself height direction setting, and it is flexible so that the controlling organization of casing horizontal positioned that horizon detector that draw-bar box also includes being arranged on casing top and the detection information being able to receive that horizon detector are automatically adjusted a spike.

Preferably, roller and a spike lay respectively at the left and right sides of horizon detector, and when horizon detector display left side is higher than right side, controlling organization is automatically adjusted a spike elongation, until during horizon detector display balance, controlling organization quits work; When horizon detector display right side is higher than left side, controlling organization is automatically adjusted a spike and shrinks, until during horizon detector display balance, controlling organization quits work.

Preferably, roller is universal rolling wheel.

Preferably, draw-bar box also includes the handle that is separately positioned on described casing top and left side.

Further, it is additionally provided with feet block in the right side of casing.

One according to the present invention is embodied as and preferred aspect, and a spike is electric expansion bar.

Preferably, the cross section of electric expansion bar bottom be from top to bottom and external diameter taper into trapezoidal. What make that casing stands is safer.

Preferably, described trapezoidal for right-angled trapezium, and right-angle side is near described side, roller place.

Additionally, controlling organization includes controlling circuit, power supply and information receiving processing system.

Concrete, power supply is accumulator. Replaceable, or charge at any time.

Due to the enforcement of above technical scheme, the present invention compared with prior art has the advantage that

The present invention, by the setting of horizon detector and controlling organization, is automatically adjusted the height of leg so that draw-bar box stably can be placed in any plane, and meanwhile, simple in construction, it is convenient to implement, and cost is low.

Accompanying drawing explanation

Fig. 1 is the schematic front view according to draw-bar box of the present invention;

Wherein: 1, casing; 2, pull bar; 3, roller; 4, spike is propped up; 5, horizon detector; 6, handle; 7, feet block.

Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described in detail.

Referring to Fig. 1, the draw-bar box that the present embodiment provides, it includes casing 1, pull bar 2, is positioned at the roller 3 bottom casing 1 and a spike 4, this spike 4 can stretch along oneself height direction setting, horizon detector 5 that draw-bar box also includes being arranged on casing 1 top and to be able to receive that the detection information of horizon detector 5 is automatically adjusted a spike 4 flexible so that the controlling organization (not shown) of casing 1 horizontal positioned.

In this example, roller 3 and a spike 4 lay respectively at the left and right sides of horizon detector 5, and when horizon detector 5 display left side is higher than right side, controlling organization is automatically adjusted a spike 4 and extends, until during horizon detector 5 display balance, controlling organization quits work; When horizon detector 5 display right side is higher than left side, controlling organization is automatically adjusted a spike 4 and shrinks, until during horizon detector 5 display balance, controlling organization quits work.

Further, propping up spike 4 is electric expansion bar.

Meanwhile, the cross section of electric expansion bar 4 bottom be from top to bottom and external diameter taper into trapezoidal. What make that casing 1 stands is safer.

In this example, trapezoidal for right-angled trapezium, and right-angle side is near side, roller place.

Concrete, controlling organization includes controlling circuit, power supply and information receiving processing system (although not showing the concrete structure of controlling organization in figure, but In the view of those skilled in the art, that is general knowledge, therefore omits).

Further, power supply is accumulator. Replaceable, or charge at any time.

Meanwhile, involved in this example roller 3 is universal rolling wheel. It is easy to the movement of draw-bar box.

Additionally, above-mentioned draw-bar box also includes the handle 6 being separately positioned on casing 1 top and left side.

Further, it is additionally provided with feet block 7 in the right side of casing 1. Make the draw-bar box can either be laterally disposed, it is also possible to vertically to place.

Above the present invention is described in detail; its object is to allow the personage being familiar with this art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; the equivalence that all spirit according to the present invention are made changes or modifies, and all should be encompassed in protection scope of the present invention。
