Detailed description of the invention
The utility model is further illustrated below by way of specific embodiment.
Embodiment 1
What adopt fork elevating heightens a platform, and comprise desktop 1, bracing frame 2, scissors fork 3 and air spring 4, as shown in FIG. 1 to 3, concrete structure is:
Bracing frame 2 is located on ground by the supporting leg 21 of bottom, the top of bracing frame 2 connects the bottom of desktop 1 by fourth officer scissors fork 3, wherein two secondary scissors forks 3 are oppositely arranged the both sides being located at bracing frame 2 respectively, angle between the scissors fork 3 be oppositely arranged in scissors fork 3 is at 0 ~ 45 °, the present embodiment is got 0 scissors be namely oppositely arranged and is pitched 3 parallel to each other, another two secondary scissors forks 3 be located at successively bracing frame 2 another side and and the scissors be oppositely arranged pitch 3 and vertically to arrange.
Scissors pitches 3 as shown in Figure 2: every secondary scissors fork 3 comprises two braces, 31, three bearing pins, 32, two rollers 33 and two slide rails 34, the middle part of two braces 31 is by the rotating connection of bearing pin 32, the top of a brace 31 and bottom are respectively equipped with bearing pin 32 and roller 33, the top of another root brace 31 and bottom are respectively equipped with roller 33 and bearing pin 32, namely the two ends at every secondary scissors two ends and bottom of pitching 3 tops are all respectively equipped with bearing pin 32 and roller 33, two slide rails 34 are located at the bottom of desktop 1 and the top of bracing frame 2 respectively;
The bearing pin 32 of scissors fork 3 by top and bearing pin 32 bottom of rotating connection desktop 1 and the top of bracing frame 2 respectively of bottom, scissors is pitched in the slide rail 34 bottom the roller 33 on 3 tops and the roller 33 difference inserted in table top plate 1 of bottom and in the slide rail 34 at bracing frame 2 top.
The quantity of air spring 4 is equal with quantity that the is relative and scissors be arranged in parallel fork 3, the cylinder body of air spring 4 is fixed on bracing frame 2, the mobile terminal of air spring 4 piston rod connects relatively rotationally and in the scissors be arranged in parallel fork 3, top is provided with the brace 31 of roller 33, the cylinder body of air spring 4 all connects drag-line 41, air spring switch 42 that drag-line 41 is connected.
In the present embodiment, air spring 4 selects self-locking air spring or balanced type air spring.
Air spring 4 is that one can play support, buffering, braking, the highly component of the function such as adjustment and angular adjustment, air spring 4 is as shown in Figure 3: comprise pressure cylinder 41, piston rod 42, piston 43 and seal guide sleeve 44, in pressure cylinder 41, blanketing gas or gas mixture are as power transmission medium, air pressure in pressure cylinder 41 is much larger than external atmosphere pressure, be generally 3 ~ 30 times of external atmosphere pressure, the openend of pressure cylinder 41 is provided with seal guide sleeve 44, the piston 43 with inner wall sealing is provided with in pressure cylinder 41, the inner of piston rod 42 to be penetrated in pressure cylinder 41 by seal guide sleeve 44 and is fixed on piston 43, piston 43 having through hole makes the air pressure at pressure cylinder 41 inner carrier 43 two ends keep balance.After External Force Acting is on piston rod 42, piston rod 42 drives piston 43 to slide along pressure cylinder 41 inwall, because the air pressure in pressure cylinder 41 is much larger than external atmosphere pressure, and the cross-sectional area of piston rod 42 is less than the cross-sectional area of piston, thus produce pressure differential to realize the motion of piston rod 42, the movement of piston 43 makes the air pressure of pressure cylinder 41 inner carrier 43 both sides uneven, and therefore gas impels piston 43 both sides air pressure balance by the flow therethrough on piston 43.Air spring has the advantages such as speed is relatively slow, dynamic force change little, easy control, elastic curve approximately linear, adopts self-locking air spring or balanced type air spring can realize stopping in the optional position of stroke.For 60kg top lift air spring, air spring can bear the downforce of 160kg, and latching force can reach 1000kg; As long as there is a pressure cylinder normally to work, can ensure that total can not tilt to collapse at any height.
If the scissors distance of pitching between the bearing pin 32 on 3 tops and roller 33 is a when air spring 4 piston rod is extrapolated to outermost end, when being pulled to inner terminal in air spring 4 piston rod, the scissors distance of pitching between the bearing pin 32 on 3 tops and roller 33 is b, then 0.5a<b<a, the present embodiment gets b=0.6a.
When the present embodiment uses, when needs regulate height, press air spring switch 42, air spring 4 is unlocked state, pop-up subsequently or press down desktop 1, desktop 1 pitches a brace 31 of 3 to air spring 4 transmission of pressure or pulling force by scissors, air spring 4 is promoted by piston rod or pulls scissors to pitch the brace 31 of 3 to play power-assisted effect, when air spring 4 piston rod promotes brace 31, the roller 33 that scissors pitches 3 tops and bottom moves laterally along slide rail 34 respectively, scissors fork 3 shrinks and height reduction gradually, thus play the effect reducing desktop 1 height, when air spring 4 piston rod pulls brace 31, the roller 33 that scissors pitches 3 tops and bottom moves to the inside along slide rail 34 respectively, scissors fork 3 opens gradually and highly raises, thus play the effect of rising desktop 1 height, when the scissors fork 3 be arranged in parallel is by manpower and the lifting of air spring 4 active force, the effect of vertically disposed scissors fork 3 its auxiliary positioning, to ensure that desktop 1 all keeps level in whole lifting process.
