Abstract
The utility model relates to a kind of climbing stairs ladder type draw-bar box, comprise pull bar, casing, switch, battery, the bottom of pull bar is arranged on the top of casing, switch is arranged on the top of pull bar, tank floor left and right sides symmetry installs a pair planetary roller device, battery is installed in the centre position of bottom half, and switch connects battery and planetary roller device.When pulling draw-bar box along stair, by the effect of planetary roller, draw-bar box directly can climb step; When pressing switch connection circuit, left and right sides planetary roller rotates, and promotes casing and advances.The climbing stairs ladder type draw-bar box that the utility model provides can stairs step reposefully, time saving and energy saving, easy to use, novel structure.
Description
Technical field
The utility model relates to a kind of draw-bar box, especially a kind of climbing stairs ladder type draw-bar box.
Background technology
One of daily necessities that draw-bar box often uses when being people's go off daily, when level road uses, pulls pull bar, and the roller of bottom half rolls the movement realizing draw-bar box on the ground, use, saves manpower.When stair activity, common draw-bar box then needs portable, wastes time and energy, especially for very difficult especially child, old man and other handicapped people.
Consult existing technical literature to find, Xu Zengbo invent a kind of can (number of patent application: 201110399169.5), utilizes cross ladder wheel and manually pulls the stair climbing function achieving luggage case at level land or the luggage case that pulls along stair; Zhang Zhigang has invented a kind of luggage case (number of patent application 201310338695. X) being convenient to stair climbing, utilizes damping block, rotating shaft and manually pulls the stair climbing function achieving luggage case; Meng Rui etc. have invented a kind of case capable of climbing stairs (Authorization Notice No.: CN201894274U), utilize roller, support and artificial dragging to achieve the stair climbing function of chest.Above-mentioned chest bumpy motion when stair climbing with stair climbing function, still pulls difficulty when chest is heavier, there is certain defect.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing stair climbing chest technical scheme, the utility model provides a kind of stable movement, time saving and energy saving, structure simple climbing stairs ladder type draw-bar box.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of climbing stairs ladder type draw-bar box, comprise pull bar, casing, switch, battery, the bottom of pull bar is arranged on the top of casing, switch is arranged on the top of pull bar, tank floor left and right sides symmetry installs a pair planetary roller device, and battery is installed in the centre position of bottom half, and switch connects battery and planetary roller device.
Described planetary roller device is made up of three identical rollers, three identical pinions, gear wheel, bracing frame, motors, and motor connects gear wheel, gear wheel and three pinion external toothings, and three pinions connect three rollers respectively; Three pinions and three rollers are arranged on three ends of bracing frame, each end of bracing frame are provided with a pinion and a roller; Bracing frame kink is on casing, and bracing frame can around body pivot.
In described planetary roller device, three identical pinion angles are between any two 120 degree.Described battery connects two motors by switch.
The beneficial effects of the utility model:
(1) stable movement.The planetary roller of bottom half uses the mode that 1 gear wheel drives 3 pinions, 3 pinions drive 3 rollers more respectively, because gear-driven gearratio is constant, stable movement, ensure that the stationarity of draw-bar box stair climbing;
(2) time saving and energy saving.Rotatable after electrical power in planetary roller, thus drive roller to rotate, there is impetus forward to casing, save manpower.
Accompanying drawing explanation
Fig. 1 is chief component schematic diagram in climbing stairs ladder type draw-bar box embodiment of the present utility model;
Fig. 2 is planetary roller part schematic diagram in climbing stairs ladder type draw-bar box embodiment of the present utility model;
Fig. 3 is the schematic diagram of climbing stairs ladder type draw-bar box embodiment breaker in middle of the present utility model, battery and motor built-up circuit.
Detailed description of the invention
Below, with reference to accompanying drawing, a kind of climbing stairs ladder type draw-bar box involved by the utility model is elaborated.
As shown in Figure 1, a kind of climbing stairs ladder type draw-bar box, is made up of switch 1, pull bar 2, casing 3, a pair planetary roller device 4, battery 5.Switch 1 is arranged on the top of pull bar 2; The bottom of pull bar 2 is arranged on the top of casing; A pair of identical planetary roller device 4 symmetry is arranged on the left and right sides bottom casing 3; Battery 5 is arranged on the centre position bottom casing 3.
As shown in Figure 2, planetary roller device 4 is made up of three identical roller 4a, three identical pinion 4b, gear wheel 4c, bracing frame 4d, motor 4e; The main shaft of motor 4e is connect by flat key and gear wheel 4c, gear wheel 4c and three pinion 4b external toothing, and three pinion 4b can drive three roller 4a to rotate respectively; Three pinion 4b and three roller 4a are arranged on three ends of bracing frame 4d, each end of bracing frame 4d are provided with an a pinion 4b and roller 4a; Three pinion 4b angle is between any two 120 degree; Bracing frame kink in planetary roller, can around body pivot on casing.
As shown in Figure 3, press 1, switch and connect circuit, battery 5 is powered to two motor 4e, and two motor 4e rotate.
Operation principle of the present utility model is:
When draw-bar box uses on level land, manually pull 2, pull bar to realize the motion of casing, when casing is heavier, press switch 1, under the effect of motor 4e, drive case 3 is moved or indirect labor pulls; Draw-bar box, when stair climbing, manually pulls pull bar 2, and rely on the stair climbing motion that a pair planetary roller device 4 realizes casing, press switch 1, planetary roller 4 rotates the stair climbing motion promoting casing 3, saves manpower; Battery 5 electricity can use charger to charge to it when using up.
