Embodiment
Below by specific embodiment armstrong's patent formula arrangement for adjusting height of the present invention is described in further detail.
As Fig. 1, shown in Figure 2, armstrong's patent formula arrangement for adjusting height, the pedestal 1 that comprises a hollow, as shown in Figure 3, described pedestal 1 comprises pedestal outer tube 11, pedestal outer tube 11 inside are provided with pedestal liner 12, described pedestal outer tube 11 and pedestal liner 12 are evenly distributed with seven pilot holes 13 vertically on corresponding mutually position, pedestal 1 movable set is in the outside of elevating lever 2, pedestal outer tube 11 is provided with four liner adjusting screw 14, the outer wall of the top of liner adjusting screw 14 and pedestal liner 12 fits, clockwise during turn liner adjusting screw 14, pedestal liner 12 is fitted to elevating lever 12, thereby the gap between pedestal liner 12 and the elevating lever 12 is dwindled; In like manner, counterclockwise during turn liner adjusting screw 14, can make the gap enlargement between pedestal liner 12 and the elevating lever 12.Be movably set with backstay 3 in the described elevating lever 2, described backstay 3 is movably arranged on elevating lever 2 inside by bearing pin 4, described bearing pin 4 can also be made the position-limiting action that elevating lever 2 is adjusted to lowest order, the hook-shaped pin 31 of the lower end of backstay 3 for matching with pilot hole 13, on the elevating lever 2 through hole is arranged, elevating lever 2 is stretched out in the end of hook-shaped pin 31 from through hole, the upper end of backstay 3 is a driving lever handle 32, described driving lever handle 32 stretches out elevating lever 2, be provided with spring 5 between described backstay 3 and the elevating lever 2, described spring 5 is positioned at the opposite side of hook-shaped pin 31, backstay 3 is provided with a cavity 7 that matches with spring 5, described spring 5 is arranged in cavity 7, hook-shaped pin 31 inserts in the pilot hole 13 of pedestal liner 12 under the effect of spring 5 elastic force automatically, the bottom of described elevating lever 2 is provided with spacing lock bolt 6, is used to prevent that elevating lever 2 is deviate from above pedestal 1 when highly regulating.
Principle of work of the present invention is: during use, pedestal outer tube 11 fixes with the fixed part of equipment or mechanism, as the bed frame of sick bed, the chair frame of transfusion chair etc.; The upper end of elevating lever 2 fixes with the equipment that needs work highly to regulate or the movable part of mechanism, as the guardrail of sick bed, the handrail of transfusion chair etc.
Height adjustment process: the movable part of holding equipment or mechanism, and hold driving lever handle 32 with finger simultaneously, driving lever handle 32 is upwards carried and do not loosed one's grip, this moment, backstay 3 meetings be that the center rotates with bearing pin 4, the hook-shaped pin 31 of backstay 3 lower ends breaks away from from the pilot hole 13 of pedestal liner 12, then in the indentation elevating lever 2, this moment, elevating lever 2 can slide up and down in pedestal 1, after sliding into desired height, unclamp driving lever handle 32, this moment is under the elastic force effect of spring 5, backstay 3 is that the center rotates with bearing pin 4, the hook-shaped pin 31 of backstay 3 lower ends inserts in the pilot hole 13 of pedestal outer tube 11 and pedestal liner 12 under the effect of spring 5 elastic force automatically, thereby with location between backstay 3 and the pedestal 1, thereby reach the purpose of regulating height.In the above-mentioned adjustment process, as shown in Figure 4, when elevating lever 2 drops on bearing pin 4 and the pedestal 1 end in contact, be the lowest order of highly regulating this moment, this moment, hook-shaped pin 31 was suspended from the below of pedestal 1, no longer played the effect of location, and this moment, bearing pin 4 played the effect spacing and location; As shown in Figure 5, when elevating lever 2 rises to spacing lock bolt 6 with 1 time end in contact of pedestal, be the most significant digit of highly regulating this moment, the length of pedestal 1 equates with hook-shaped pin 31 bottoms to the distance between the spacing lock bolt 6, this moment, the bottom of pedestal 1 was held on the spacing lock bolt 6, hook-shaped pin 31 is held on the upper end of pedestal 1, plays the effect of location equally.
