Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is elaborated.
Embodiment: the portable stair climbing draw-bar box of one as Figure 1-5, comprise draw-bar box body 1, described draw-bar box body 1 side is along its length provided with telescopic pull bar 4, described pull bar 4 comprises two telescopic stretching bar 4-1 and connects the connecting rod 5 of two stretching bar 4-1, also comprises the flat wheel plate 2 that the back side that is arranged on draw-bar box body 1 and pull bar 4 bottom are rotationally connected to take turns linkage; Described flat wheel plate 2 is laid by some rollers 14 slided for draw-bar box body 1; As shown in Figure 5; When will go upstairs, people stands in the connecting rod 5 that stair left-hand seat hauls draw-bar box body 1, at this moment draws draw-bar box body 1 and stair 3 step to present an angle.Press lower guide rod button 7, flat wheel plate 2 departs from draw-bar box body 1 under self gravitation, is laid on stair 3 step; Press the guide rod button 7 on lower connecting rod 5, the angle of flat wheel plate 2 and draw-bar box body 1 is locked; People hauls draw-bar box when moving up, and draw-bar box is positioned on flat wheel plate 2, and flat wheel plate 2 rolls on stair 3 step.After stair 3 are covered, packed up by flat wheel plate 2, unclamp guide rod button 7, under guide rod spring 6 acts on, flat wheel plate 2 is fixed on draw-bar box recess; The conversion of motion of draw-bar box and stair is the relative motion of flat wheel plate and stair by flat wheel plate; When special construction due to flat wheel plate 2 makes draw-bar box go upstairs, steadily laborsaving.
Wheel linkage comprises lever 11, with the rigidly connected braked wheel 13 in described lever 11 end and the guide rod shaft 9 that is connected with pull bar 4; Described lever 11 is fixed on draw-bar box body 1 by lever pin 10; This lever pin 10 is located in lever 11 bottom; Also comprise slide bar 16, described braked wheel 13 is mobile by being engaged in slide bar 16 of brake axle 12; This slide bar 16 is fixed on draw-bar box body 1; This slide bar 16 is provided with driven shaft 17; Along the driven pulley 15 that this driven shaft 17 rotates; This driven pulley 15 is connected with described flat wheel plate 2; Driven pulley 17 is fixed on draw-bar box body 1;
After flat wheel plate 2 is put down, be laid on stair face, after pinning guide rod button 7, stretching bar 4-1 is pulled up, and under lever 11 acts on, braked wheel 13 moves down along slide bar 16 and contacts with driven pulley 15; Driven pulley 15 cannot rotate, and therefore the angle of flat wheel plate 2 and draw-bar box body 1 will be fixed, and draw-bar box body 1 can rely on flat wheel plate 2 to slide on stair.
Guide rod spring 6 is provided with in connecting rod 5; Described guide rod spring 6 is for controlling the opening and closing of guide rod button 7; State before can returning to after making guide rod button 7 released; Locking press button 7 and stretching bar 4-1 are rigidly connected, and pin this button then flat wheel plate of lockable.In an initial condition, under the elastic force of guide rod spring 6, button and stretching bar 4-1 are positioned at pull bar least significant end.Pin guide rod button 7 back-guiding rod to be pulled up, flat wheel plate 2 is lockable; Unclamp guide rod button 7, act on lower guide rod button 7 return to least significant end again at guide rod spring 6, flat wheel plate 2 unlocks.
The container cavity 8 placing flat wheel plate 2 is formed in the middle part of draw-bar box body 1 back side; The distance of this container cavity 8 side is less than the width of described flat wheel plate 2; Flat wheel plate 2 can be retracted into magazine ac chamber 8 place.Container cavity 8 place lateral distance is slightly less than flat wheel plate 2 width, and therefore flat wheel plate can be stuck in recess and not come off.Only need exert oneself a little when going upstairs separable.
Roller 14 is laid staggeredly on flat wheel plate 2; Roller 14 diameter is less, is staggeredly placed; In rolling process, add the area of contact stair 3, and high low head between the wheel of roller 14 is little, roll steadily, vibration sense is little.
Take to increase this convenience that formula stair climbing draw-bar box collects and receive, stretching bar 4-1 is elastic telescopic buffer bar.
Be convenient to pull bar 4 and people's lever 11 and keep stable, this pull bar 4 and described lever 11 L-shaped.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Although more employ Reference numeral in figure herein: draw-bar box body 1, flat wheel plate 2, stair 3, pull bar 4, stretching bar 4-1, connecting rod 5, guide rod spring 6, guide rod button 7, container cavity 8, guide rod shaft 9, lever pin 10, lever 11, brake axle 12, braked wheel 13, roller 14, driven pulley 15, slide bar 16, term such as follower shaft 17 grade, but do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
