[specific embodiment]
In the lifting support frame of Fig. 1 the utility model embodiment 1 extremely shown in Figure 4, comprise the fixed head 1 that constitutes parallel-crank mechanism, carriage 2 and 2 support bars 3 and 4, in parallel-crank mechanism, fixed head 1 is a frame, 2 support bars 3 and 4 are crank, and carriage 2 is a connecting rod, and 2 support bars 3 and 4 are L shaped, the lower end of 2 L shaped support bars and fixed head 1 are hinged, and the upper end of 2 L shaped support bars and carriage 2 are hinged.The screw hole 1a that usefulness is installed is arranged on the fixed head 1.
2 L shaped support bars 3 and 4 are formed by long-armed and galianconism, long-armed 301 and 401 and fixed head 1 hinged, galianconism 302 and 402 and carriage 2 hinged.Auxiliary connecting rod 5 is hinged with 2 L shaped support bars 3 and 4 respectively, and pin joint 6 is positioned at the connecting portion of long-armed 301 and galianconism 302 of L shaped support bar 3; Pin joint 7 is positioned at the connecting portion of L shaped support bar long-armed 401 and galianconism 402.Auxiliary connecting rod 5 and 1,2 support bars 3 of fixed head and 4 same formation parallel-crank mechanisms are to strengthen the rigidity of lifting support frame.
As shown in Figure 3 and Figure 4, carriage 2 is the door font, for when lifting support frame folds, carriage 2 can not interfere with the long-armed of L shaped support bar, carriage 2 lower end pin joints 8 to the vertical range H of carriage 2 upper inner greater than the upper end pin joint 9 of L shaped support bar distance h to the long-armed outside of L shaped support bar.Equally, convenient for the rigidity and the riveted that strengthen lifting support frame, between 2 pin joints of carriage 2, increased by 1 auxiliary connecting rod 10.
Be positioned at the outside of support bar 3 long-armed 301, riveting has hanger pin 11 on fixed head 1, opens stopping means as bracing frame.Open extreme position at bracing frame, the outside of support bar 3 long-armed 301 leans against on the hanger pin 11.At this moment, the angle of the upper and lower side pin joint 6 of L shaped support bar and 12 line and plumb line is not more than 5 °, and L shaped support bar is a compression rod, is in self-locking state, can improve the force-bearing situation of whole lifting support frame.In the present embodiment, 6 and 12 the line and the angle of plumb line are 0 °, and promptly both overlap.
As shown in Figure 4, fixed head 1 sees it is S shape in the side, the stopping means the when 1b that tops bar of S shape fixed head folds as bracing frame.Fold extreme position at bracing frame, 2 L shaped support bars 3 and 4 long-armed 301 and 401 overlap, galianconism 302 and 402 is towards the below.At this moment, long-armed 401 of support bar 4 lean against on the 1b that tops bar of fixed head.
One end and the fixed head 1 of atmospheric pressure pole 13 are hinged, the other end and L shaped support bar 3 long-armed 301 hinged.Open extreme position at bracing frame, when long-armed 301 the outside leaned against on the hanger pin 11, the pin joint 14 of atmospheric pressure pole 13 and L shaped support bar is positioned at atmospheric pressure pole, fixed head 1 pin joint 15 and L shaped support bar is long-armed, the top of fixed head 1 pin joint 12 lines.
For safety, after opening, bracing frame needs to fix, and fixture comprises hook 16 and hanger pin 11, and hanger pin 11 is fixed on the fixed head 1, opens stopping means as bracing frame simultaneously.Hook 16 is sleeved on the jointed shaft of atmospheric pressure pole and L shaped support bar, can rotate.Open extreme position at bracing frame, hook 16 hangs on the hanger pin 11 fixes bracing frame.
Impulsive force when folding in order to reduce bracing frame, buffer 17 are installed on the fixed head 1, when bracing frame when folding extreme position, the contact 17a of the long-armed 401 contact buffers of L shaped support bar 4 realizes buffering.
The support bar of the L shaped bending of lifting support frame of present embodiment is littler than straight-bar length, and the horizontal displacement of platen can reduce.When bracing frame folded, the part of carriage 2 can drop to the bottom of lifting support frame, and when bracing frame was opened, the part that carriage 2 dropped to the lifting support frame bottom originally protruded upward, and can strengthen the lifting altitude of bracing frame.So present embodiment is that a kind of rise is big, the lifting support frame that horizontal displacement is little.
Be at the lifting support frame of the utility model embodiment 2 shown in Figure 5 and the difference of embodiment 1, in embodiment 1, the extreme position that folds at bracing frame, the pin joint 14 of atmospheric pressure pole 13 and L shaped support bar is positioned at substantially that atmospheric pressure pole, fixed head 1 pin joint 15 are long-armed with L shaped support bar, on fixed head 1 pin joint 12 lines, perhaps slightly more on the lower side.Like this, the state of bracing frame is more stable, and the power of going straight up to that needs when opening bracing frame is bigger.And in embodiment 2, at the extreme position that bracing frame folds, the pin joint 14 of atmospheric pressure pole 13 and L shaped support bar is positioned at atmospheric pressure pole, fixed head 1 pin joint 15 and L shaped support bar is long-armed, the top of fixed head 1 pin joint 12 lines.As long as the carriage 2 with bracing frame upwards one draws lightly, bracing frame just can be taken advantage of a situation under the effect of atmospheric pressure pole 13 outside tension force and be opened, and this structure helps reducing to open the needed strength of bracing frame.
The contour structures of the utility model embodiment 2 liftable supporters is made of 101,102 and 1 middle brace rods 201 of lifting support frame of 2 embodiment 1 as shown in Figure 5.Left and right sides lifting support frame 101,102 is installed relatively, the parts symmetric arrangement.Middle brace rod 201 is used for connecting each 1 close L shaped support bar 3 in the left and right sides lifting support frame 101,102.Middle brace rod 201 can guarantee 101, the 102 synchronous synergetic work of left and right sides lifting support frame.
The utility model embodiment 3 has the furniture of lifting platen, comprises the furniture body, and embodiment 2 described liftable supporters are housed between lifting platen and furniture body.2 fixed heads of left and right sides lifting support frame are installed on the side plate 300 of furniture body with screw; Liftable platen is installed on 2 carriages of left and right sides lifting support frame with screw.
