lower pole

23,26 apportion both sides corresponding mutually.

After the above-mentioned member assembling, on,

lower fulcrum bar

23,27 and last,

lower link

24,25 constitute the parallelogram of the activity of a hinged state, simultaneously owing to be hinged with adjusting cylinder 22, make the motion state of this parallelogram and fixed position fully by the switch of this adjusting cylinder 22 and the determining positions of plunger elongation, the position of regulating cylinder 22 should be as far as possible near upper rack posts 23, use and obtain maximum connecting rod lifting moment, Fig. 1 shows that tea table stretches the extreme higher position, regulate cylinder 22 and close this moment, its two pin joints length is fixed, tea table is stationary state, and can make tea table this moment, desk, purposes such as workbench; When need lower the tea table height, depress regulating handle 222, regulate cylinder 22 and be compressed state, as long as human defeats tea table table top 1, table top 1 can descend, and upper and lower connecting

rod

24,25 is synchronous rotation around pin joint, when highly being adjusted to desired height, discharge regulating handle 222, adjusting cylinder 22 is closed and is metrostasis, and table top 1 is in the desired height position; Tea table still may contract to extreme lower position, and as shown in Figure 4, so the sofa or the seat face height of design height and both sides are identical, can constitute a doss, make equipment obtain the utmost point and make full use of, to naval vessel or the strict occasion of other space utilizations, this kind combination is the measure with excellent effect; When needs when minimum or low level is regulated tea table and is risen, as long as press down regulating handle, open and regulate cylinder 22, the plunger rod 223 of regulating cylinder 22 makes the two pin joint spacings elongation of regulating cylinder 22 under gas pressure, thereby make,

lower link

24,25 rotate around pin joint, and then reach the function that table top 1 raises, discharge regulating handle 222 and promptly can be positioned on desired height, when the tea table table top is pressed with loading greatly, then can have gentle hands lift the lifting power of table top as assistant cylinder, make the design size of regulating cylinder obtain choose reasonable, in order to avoid, cause waste owing to special loading needs to take the cylinder of specification greatly.
