In figure: 1, base, 2, table case, 3, lifting table leg, 4, table frame, 5, desktop, 6, sliding bar, 7, chute, 8, slide bar, 9, slot pulling, 10, cushion, 11, guiding sliding part, 12, sliding sleeve, 13, slip revolving part, 14, sliding tray, 15, slip spill spin block, 16, slide unit A, 17, slide unit B.
The specific embodiment
Should comprise base 1, table case 2, lifting table leg 3, table frame 4 and desktop 5 with the lifting desk of dual-purpose desktop.On base 1, by lifting table leg 3, a case 2 is installed, lifting table leg 3 consists of elevating screw.
In table case 2, be symmetrically installed with ratchet cycle lifting device, ratchet Circularly liftable lever apparatus top is installed with a frame 4, in table frame 4, by chute 7, is movably installed with desktop 5.Desktop 5 one end bilateral symmetry are provided with slide bar 8, and desktop 5 other end middle parts are provided with slot pulling 9, and the lower surface of desktop 5 is provided with the cushion 10 of sponge material.
Ratchet cycle lifting device consists of sliding bar 6, guiding sliding part 11, sliding sleeve 12, slip revolving part 13, on sliding sleeve 12, be vertically arranged with sliding tray 14, on sliding sleeve 12 upper surfaces of sliding tray 14 both sides, be respectively arranged with slide unit A16 and slide unit B17, in sliding sleeve 12, be movably installed with sliding bar 6, sliding bar 6 movable upper ends are set with guiding sliding part 11, and the lower surface of guiding sliding part 11 is curved surface shape.Sliding bar 6 lower ends are movably installed with slip revolving part 13, are provided with slip spill spin block 15 on the circumference of slip revolving part 13, and slip spill spin block 15 is slidably connected with sliding tray 14.
Lead while installing sliding part 11 and sliding sleeve 12 of ratchet cycle lifting device is fixedly installed in a case 2, and the top of sliding bar 6 is fixedly connected with a frame 4.
In the time of should using with the lifting desk of dual-purpose desktop, with hand, hold respectively two lifting table legs 3 and rotate backward each other, can reach the object of adjusting desk height.
The slot pulling 9 of finger being put into desktop 5 can start desktop 5, then desktop 5 is promoted along chute 7, and the slide bar 8 on desktop 5 is replaced to the other end of table frame 4 from one end of table frame 4, and 180 degree stir desktop 5, can reach the object that desktop 5 commutates.
When student need to take article in table case 2, the left and right sides the horizontal ends that with hand, pinch respectively a frame 4 rise until cannot continue upwards, in this course, the sliding bar 6 of ratchet cycle lifting device drives slip revolving part 13 synchronously to rise along guiding sliding part 11, and depart from sliding sleeve 12, while rising to peak, the peak of the slip spill spin block 15 on slip revolving part 13 contacts with the left side, lower surface of guiding sliding part 11, because the lower surface of guiding sliding part 11 is the curved surface shape of V font.Under the effect of rising pulling force, the component that rising pulling force produces forces slip spill spin block 15 to drive slip revolving part 13 to rotate counterclockwise, until coincide with the right side, lower surface of guiding sliding part 11.The slide unit B17 now sliding on spill spin block 15 and sliding sleeve 12 is in same axle center.
After the pull-up action of table frame 4 completes, along the guiding sliding part 11 light table frame 4 of pressing downwards, the spill spin block 15 that makes to slide contacts with slide unit B17, and under the effect of pressure component, slip spill spin block 15 rotates counterclockwise along slide unit B17, until stopped by slide unit A16.Now can unclamp the both hands article of taking easily in table case 2.
When desktop 5 falls to restoring, again by the left and right sides horizontal ends that hand pinches respectively a frame 4, rise until cannot continue upwards, in this course, because the peak of the slip spill spin block 15 on slip revolving part 13 contacts with the right side, lower surface of guiding sliding part 11, under the effect of rising pulling force, the component that rising pulling force produces forces slip spill spin block 15 to drive slip revolving part 13 to rotate counterclockwise, until coincide with the left side, lower surface of guiding sliding part 11.The slide unit A16 now sliding on spill spin block 15 and sliding sleeve 12 is in same axle center.
After the pull-up action of table frame 4 completes, along the guiding sliding part 11 light table frame 4 of pressing downwards, the spill spin block 15 that makes to slide contacts with slide unit A16, and under the effect of pressure component, slip spill spin block 15 rotates counterclockwise along slide unit A16, until fall into sliding tray 14.Now slide revolving part 13 friction in down stroke eliminate, can be along sliding tray 14 until fall into sliding sleeve 12 bottoms.Restore the whereabouts that completes desktop 5.
