Embodiment
The embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.
Embodiment：A kind of portable stair climbing draw-bar box as Figure 1-5, including draw-bar box body 1, the draw-bar box
The side of body 1 along its length is provided with telescopic pull bar 4, the pull bar 4 include two telescopic stretch rod 4-1 with
And two stretch rod 4-1 of connection connecting rod 5, in addition to be arranged on the back side and the bottom of pull bar 4 of draw-bar box body 1 to take turns bar machine
Structure rotates the flat wheel plate 2 of connection；Laid on the flat wheel plate 2 by some rollers 14 slided for draw-bar box body 1.Such as Fig. 5
It is shown；When will go upstairs, people, which stands, hauls the connecting rod 5 of draw-bar box body 1 in stair left-hand seat, at this moment draws the He of draw-bar box body 1
An angle is presented in the step of stair 3.Lower guide rod button 7 is pressed, flat wheel plate 2 departs from draw-bar box body 1 under self gravitation, is laid in
On the step of stair 3；The guide rod button 7 on lower connecting rod 5 is pressed, the angle of flat wheel plate 2 and draw-bar box body 1 is locked；People hauls
When draw-bar box is moved up, draw-bar box is located on flat wheel plate 2, and flat wheel plate 2 is rolled on the step of stair 3.Stair 3 cover it
Afterwards, flat wheel plate 2 is packed up, unclamps guide rod button 7, under the effect of guide rod spring 6, flat wheel plate 2 is fixed on draw-bar box recess；It is flat
Wheel plate is by relative motion that the conversion of motion of draw-bar box and stair is flat wheel plate and stair；Because the special construction of flat wheel plate 2 makes
It is steady laborsaving when draw-bar box is gone upstairs.
Taking turns linkage includes lever 11, is connected with the rigidly connected braked wheel 13 in the end of lever 11 and with pull bar 4
Guide rod shaft 9；The lever 11 is fixed on draw-bar box body 1 by lever pin 10；The lever pin 10 is located in lever 11
Bottom；Also include slide bar 16, the braked wheel 13 is moved by the cooperation of brake axle 12 in slide bar 16；The slide bar 16 is fixed
In on draw-bar box body 1；The slide bar 16 is provided with driven shaft 17；The driven pulley 15 rotated along the driven shaft 17；The driven pulley 15
On be connected with the flat wheel plate 2；Driven shaft 17 is fixed on draw-bar box body 1；After flat wheel plate 2 is laid down, stair are laid in
On face, pin after guide rod button 7, stretch rod 4-1 is pulled up, under the effect of lever 11, braked wheel 13 is along slide bar 16 to moving down
It is dynamic to be contacted with driven pulley 15；Driven pulley 15 can not be rotated, therefore the angle of flat wheel plate 2 and draw-bar box body 1 will be fixed,
Draw-bar box body 1 can rely on flat wheel plate 2 to be slided on stair.
Guide rod spring 6 is provided with connecting rod 5；The guide rod spring 6 is used for the opening and closing for controlling guide rod button 7；Make
State before guide rod button 7 can be returned to after being released；Locking press button 7 is rigidly connected with stretch rod 4-1, pins the button then
The flat wheel plate of lockable.In an initial condition, button and stretch rod 4-1 are located at least significant end in pull bar under the elastic force of guide rod spring 6.
Pin the back-guiding rod of guide rod button 7 to be pulled up, flat wheel plate 2 is lockable；Guide rod button 7 is unclamped, is pressed in the effect lower guide rod of guide rod spring 6
Button 7 returns to least significant end again, and flat wheel plate 2 is unlocked.
The accommodating chamber 8 for placing flat wheel plate 2 is formed with the middle part of the back side of draw-bar box body 1；The distance of the side of accommodating chamber 8 is less than
The width of the flat wheel plate 2；Flat wheel plate 2 can be retracted at magazine ac chamber 8.Lateral distance is slightly less than flat wheel at accommodating chamber 8
The width of plate 2, therefore flat wheel plate can be stuck in recess and not fall off.Only somewhat firmly need to it be separated when going upstairs.
Roller 14 is laid staggeredly on flat wheel plate 2；The diameter of roller 14 is smaller, is staggeredly placed；In rolling process, add
The area of stair 3 is contacted, and the high low head between the wheel of roller 14 is small, rolls steadily, vibration sense is small.
The convenience that formula stair climbing draw-bar box is collected and stored is taken in order to increase this, stretch rod 4-1 is elastic telescopic buffer bar.
It is easy to pull bar 4 and people's lever 11 to keep stable, the pull bar 4 and the lever 11 are in L shapes.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or using the present invention.
