Detailed description of the invention
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 carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
One embodiment of a kind of lifting pedestal of the present invention shown in Figure 1, including: chassis 1, rotating disk 5,
Fixing seat 4, support bar 3 and mounting seat 2.Chassis 1 is used for being connected with ground, upper surface center, chassis 1
Being provided with boss 6, boss 6 upper surface and rotating disk 5 to be flexibly connected, rotating disk 5 can rotate around own axes.Fixing
Seat 4 is located at rotating disk 5 upper surface, and described fixing seat 4 top is connected with support bar 3 one end, described
Strut 3 other end is connected with the mounting seat 2 for connecting chair.Described rotating disk 5 upper surface is additionally provided with length
Short telescopic movable post 10, described support bar 3 interlude of the fixing connection in described movable post 10 upper end, described
Movable post 10 lower end is fixing connects described rotating disk 5 upper surface.With fixing seat 4 top as initial point, support bar 3
Lever construction is formed with mounting seat 2 and movable post 10.
Seeing shown in Fig. 2 and Fig. 3, described movable post 10 includes guide pillar 11 and is sheathed on described guide pillar 11
Guide pin bushing 11, described guide pin bushing 11 inner bottom part is provided with worm gear 15, and described worm gear 15 is movable with described guide pin bushing 11 even
Connect and have the first motor 13 by worm screw 14 drive connection, in described worm gear 15, being provided with screw thread by thread bush
Post (diagram is not given), described threaded post (diagram is not given) top is fixing connects described guide pillar 11.
In the present embodiment, described support bar 3 quantity is two and is set in parallel.The support be arrangeding in parallel
Bar 3 can ensure that the line of end in the same direction of two support bars 3 remains in vertical straight line states, from without drawing
Play the inclination of mounting seat 2, it is ensured that the seat being connected with mounting seat 2 will not run-off the straight.
The present invention in working order under, when needs improve height of seat time: the first motor 13 starts, drive snail
Taking turns 15 worm screw 14 assemblies to rotate, worm gear 15 persistently rotates, and is located at the threaded post in worm gear 15 thus at spiral shell
Ejecting under stricture of vagina effect, threaded post drives guide pillar 11 to rise, and guide pillar 11 ejects support bar 3, erecting of mounting seat 2
Nogata is promoted to displacement.Otherwise, when needs reduce height of seat, the first motor 13 inverts, and drives
Worm gear 15 worm screw 14 assembly rotates backward, and worm gear 15 persistently rotates backward, and is located at the screw thread in worm gear 15
Post thus fall under threaded function, threaded post drive guide pillar 11 decline, guide pillar 11 drives at support bar 3
Lower decline, the vertical direction displacement of mounting seat 2 is minimized.
At present, rotating of seat relies on the rotation of rotating disk to realize mostly.But when needs stop rotating disk rotation
It is used mostly manual braking device, fixture block is i.e. 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 simple in construction,
If but rotary inertia is excessive, the dynamics stepping on service brake the most just requires bigger, and the mode of artificial braking is the most aobvious
It is painstaking to compare.And, it is impossible to keep the state that rotating disk is fixed or loosened for a long time.
As the further optimization to the present embodiment, also include a locking device 20.See Fig. 4, locking dress
Put 20 to include being connected and be perpendicular to, by fixed plate 22 is fixing with described rotating disk 5, the screw rod that described base is arranged
23.Described screw rod 23 drive connection has the second motor 21, described second motor 21 to be located at described fixed plate 22
On.Being arranged with nut on described screw rod 23, described nut is fixedly connected with fixture block 24.Described fixture block 24 sets
Recess, described recess surface is had to be provided with the broached-tooth design 25 for increasing roughness and described recess pair
Should arrange by described boss 6 sidewall.
When needs braking stopping rotating disk 5 rotates, the second motor 21 starts, and the second motor 21 starts drive
Screw rod 23 rotates, and nut (diagram be not given) declines under screw rod 23 drives, thus drive fixture block 24 with
Boss 6 sidewall combines stopping rotating disk 5 and rotates, and fixture block 24 can be kept for a long time to combine closely with boss 6
State.When needs fixture block 24 separates with boss 6, the second motor 21 inverts, and the second motor 21 starts
Driving screw rod 23 to rotate backward, nut (diagram is not given) rises under screw rod 23 drives, thus drives
Fixture block 24 rises and separates with boss 6.
By such scheme, the lifting pedestal of traditional worm gear 15 worm screw 14 Component driver is added two grades of biographies
Dynamic assembly, the lever secondary transmission utilizing support bar 3 to be formed increases the speed that mounting seat 2 is moved, significantly
Improve the work efficiency of lifting pedestal.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
