The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
An embodiment of a kind of lifting pedestal of the present invention shown in Figure 1, comprising: chassis 1, rotating disk 5, holder 4, support bar 3 and mount pad 2.Chassis 1 is for being connected with ground, and 1 upper surface center, chassis is provided with boss 6, and boss 6 upper surfaces and rotating disk 5 are flexibly connected, and rotating disk 5 can be around self axis rotation.Holder 4 is located at rotating disk 5 upper surfaces, and described holder 4 tops are connected with support bar 3 one end, and described support bar 3 other ends are flexibly connected the mount pad 2 that is useful on connecting chair.Described rotating disk 5 upper surfaces are also provided with the telescopic movable post 10 of length, and described movable post 10 upper ends are fixedly connected with described support bar 3 interludes, and described movable post 10 lower ends are fixedly connected with described rotating disk 5 upper surfaces.Take holder 4 tops is initial point, and support bar 3 forms lever constructions with mount pad 2 and movable post 10.
Shown in Fig. 2 and Fig. 3, described movable post 10 comprises guide pillar 11 and is sheathed on the guide pin bushing 11 on described guide pillar 11, described guide pin bushing 11 inner bottom parts are provided with worm gear 15, described worm gear 15 is flexibly connected with described guide pin bushing 11 and is driven and be connected with the first motor 13 by worm screw 14, in described worm gear 15, by thread bush, be provided with threaded column (diagram does not provide), described threaded column (diagram does not provide) top is fixedly connected with described guide pillar 11.
In the present embodiment, described support bar 3 quantity are two and are set in parallel.The support bar 3 be arrangeding in parallel can guarantee that the line of end in the same way of two support bars 3 remains and be vertical straight line states, thereby can not cause the inclination of mount pad 2, guarantees that the seat being connected with mount pad 2 can run-off the straight.
Under the present invention in working order, when needs improve height of seat: the first motor 13 starts, drive worm gear 15 worm screw 14 assemblies to rotate, worm gear 15 continues to rotate, thereby the threaded column of being located in worm gear 15 ejects under threaded function, threaded column drives guide pillar 11 to rise, and guide pillar 11 ejects support bar 3, and the vertical direction displacement of mount pad 2 is promoted.Otherwise, when needs reduce height of seat, the first motor 13 reversions, drive worm gear 15 worm screw 14 assemblies to rotate backward, worm gear 15 continues to rotate backward, thereby the threaded column of being located in worm gear 15 falls under threaded function, and threaded column drives guide pillar 11 to decline, guide pillar 11 declines under support bar 3 drives, and the vertical direction displacement of mount pad 2 is minimized.
At present, the rotation of seat relies on the rotation of rotating disk to realize mostly.But when needs stop dial rotation, mostly use manual braking device, fixture block is set on rotating disk, and connects service brake by lever connecting rod mechanism; In use, step on service brake, utilize artificial braking to stop turntable rotation.Although this mode is simple in structure, if rotary inertia is excessive, the dynamics of stepping on service brake also just requires larger, and the mode of artificial braking just seems more painstaking.And, the state that can not keep for a long time rotating disk to fix or loosen.
As the further optimization to the present embodiment, also comprise a locking device 20.Referring to Fig. 4, locking device 20 comprises the screw rod 23 that is fixedly connected with described rotating disk 5 by fixed head 22 and arranges perpendicular to described base.Described screw rod 23 drives and is connected with the second motor 21, and described the second motor 21 is located on described fixed head 22.On described screw rod 23, be arranged with nut, described nut is fixedly connected with fixture block 24.Described fixture block 24 is provided with recess, and described recess surface is provided with for increasing broached-tooth design 25 and the corresponding described boss 6 sidewall settings of described recess of roughness.
When needs braking stops rotating disk 5 rotation, the second motor 21 starts, the second motor 21 starts drive screw rod 23 and rotates, nut (diagram does not provide) declines under screw rod 23 drives, thereby drive fixture block 24 to be combined with boss 6 sidewalls, stop rotating disk 5 rotations, and the state that can keep for a long time fixture block 24 and boss 6 to combine closely.When needs fixture block 24 is separated with boss 6, the second motor 21 reversions, the second motor 21 starts drive screw rod 23 and rotates backward, and nut (diagram does not provide) rises under screw rod 23 drives, thereby drives fixture block 24 risings separated with boss 6.
By such scheme, the lifting pedestal of traditional worm gear 15 worm screw 14 Component drivers is added to secondary transmission assembly, the lever secondary transmission that utilizes support bar 3 to form increases the speed that mount pad 2 moves, and has greatly improved the operating efficiency of lifting pedestal.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
