The specific embodiment
This hydraulic pressure helps upright chair to comprise chair frame 5 and is arranged on the chair back 6, seat support 10, chair leg 14, handrail and position regulating system on the chair frame 5, and described position regulating system comprises adjusting device, drive unit and control device three parts.Wherein adjusting device comprises height adjustment mechanism and has helped mechanism, regulate height for convenience, described chair leg 14 is respectively four chair legs of axial hollow, height adjustment mechanism comprises four slide bars 12, the upper end of slide bar 12 is separately fixed at four jiaos of chair frame 5, and the slide bar body is slidingly matched with the endoporus of four chair legs 14 respectively.In order after Height Adjustment is good, fixed-site all to be provided with locking mechanism in each chair leg 14 upper end and slide bar 12 contacted positions.The front portion of seat support 10 on chair frame 5, helps time-out seat support 10 to overturn around the hinge 11 of front portion by pin 11 or bolted splice, has helped mechanism to be arranged on the bottom surface of seat support 10.Hydraulic pump and hydraulic oil container 1 that is connected with hydraulic pump and telescoping hydraulic cylinder 4 that drive unit comprises motor 2, is connected with motor, what adopt in the present embodiment is 2HSTG125C * 380 type secondary telescoping hydraulic cylinders.The first stage piston of telescoping hydraulic cylinder 4 is fixedlyed connected with chair frame 5, and the second piston of telescoping hydraulic cylinder 4 is connected with the mechanism that helped on the seat support 10.Control device comprises control button 9, and control button is fixed on the position of handled easily on the handrail, control button 9 by lead respectively with motor 2, telescoping hydraulic cylinder 4 on by-pass valve control 3 be connected with locking device.In the present embodiment, described locking mechanism comprises lock sleeve 13, electromagnet 16 and coil 18, lock sleeve 13 and chair leg 14 are connected by screw thread, electromagnet 16 is two blocks of semiorbicular magnet, be arranged in the cavity between lock sleeve 13 endoporus and slide bar 12 cylindricals, be wound with coil 18 respectively on two blocks of electromagnet, the two ends of each coil are connected with control button 9 by lead respectively, and the N utmost point one end of every block of electromagnet is connected by spring 19 with the S utmost point one end of another piece electromagnet.Energising back electromagnet 16 overcomes the pressure of spring 19 attracts each other, and slide bar 12 is held tightly made required height and position locking.Cut off electric current when unlocking, two blocks of electromagnet are no longer attracted each other, and spring force promptly forces two electromagnet 16 that slide bar 12 is unclamped.In addition, locking mechanism also can adopt lock modes such as voussoir, latch or screw.In the present embodiment, the described mechanism that helped comprises guide rail 7 and slide block 8, the support of guide rail 7 by being arranged on its two ends is fixed on the back side of seat support 10 by the front and back lengthwise position, and slide block 8 is hinged on the upper end of telescoping hydraulic cylinder 4 second pistons, and the endoporus of slide block 8 and guide rail 7 are slidingly matched.For stuck between anti-limited slip block 8 and the guide rail 7, the installation site of guide rail 7 is set to the rear end and is higher than front end, makes guide rail 7 that an angle of inclination beta with respect to the horizontal plane be arranged, and in the present embodiment, β 〉=7 ° get final product.In addition, also can not adopt guide rail and be set to T shape slideway, not establish slide block and adopt the roller that matches with slideway, adopt this scheme angle of inclination beta need be set.For the height that slide bar 12 is risen carries out spacingly, be provided with inner convex platform in the upper surface of chair leg 14 endoporus, be provided with interstage sleeve 17 in the lower end of slide bar 12; Interstage sleeve 17 breaks away from mutually with the boss contact preventing when rising to extreme position.In the present embodiment, block at chair leg 14 endoporus during for fear of interstage sleeve 17 liftings, interstage sleeve 17 is hinged on the lower end of slide bar 12 by pin, can certain rotation be arranged around pin.In addition, also can under the condition that guarantees certain interval, interstage sleeve and slide bar be fixed together, or the cylindrical of interstage sleeve is set to sphere.In addition, for the chair conveniently moving, also be respectively arranged with roller 15 in the bottom of four chair legs 14.
Its operation principle is:
When adjusting height, press the rising key of control button, motor drives hydraulic pump by by-pass valve control hydraulic oil is input in the telescoping hydraulic cylinder by fuel tank, and the first stage piston that orders about telescoping hydraulic cylinder drives the chair frame and rises to desired height.Press the locking key of control button then, electromagnet is held slide bar tightly and is made the height and position locking.When dipping, reverse operating is pressed the reverse keys of control button earlier, state unlocks, press the decline key again, by the two-position four way change valve in the hydraulic system hydraulic oil in the telescoping hydraulic cylinder is emitted, the chair frame can drop to suitable position height with first stage piston.The time of pressing rising key or decline key is directly proportional with the distance of chair frame lifting, can adopt crawl when needing fine setting.
When needs help immediately, press the upset key of control button, motor drives hydraulic pump by by-pass valve control hydraulic oil is input in the telescoping hydraulic cylinder, the second piston that orders about telescoping hydraulic cylinder rises and carries out counterclockwise inclination flip by having helped mechanism to drive seat support, promotes human body to the front upper place and stands up to assist human body.On selected telescoping hydraulic cylinder, the lift of its second piston is 150 millimeters, and the maximum angle that seat support is reached when inclination flip is 60 °, the best angle of this angle for helping others and standing up smoothly.When needing seat support to reset, press the decline key again, the hydraulic oil in the telescoping hydraulic cylinder is emitted, seat support can fall after rise to horizontal level with second piston.
Hydraulic pressure helps upright chair to compare with using pneumatic shuttle, more be applicable to because of dysstasia after the sitting of waist leg illness, body weight is the people of +75 kg.
