Abstract
The utility model relates to a lifting table top which comprises a reversible motor, a fixing frame, a movable frame, a table top arranged on the movable frame, a lifting rod, a lifting rod base and a driving mechanism. The driving mechanism is electrically connected with the motor, the movable frame is fixed on the lifting rod, the driving mechanism comprises a driving gear and a toothed rack, the toothed rack is arranged on the lifting rod, the driving gear is matched with the toothed rack, and the driving gear is fixed on the fixing frame. The utility model adopts a stair transmission with one toothed rack with rapid lifting speed, the motor and the drive gear are fixed on the fixing frame, which cannot lift with the lifting of the table top, in this way, the transmission is steady when the table top is lifting, the entire gravity cannot be too high after lifting, and the table top can keep steady when using.
Description
(1) technical field
The utility model relates to a kind of Lifting platform, the Lifting platform that has of furniture especially, and the space that is applicable to household is saved and is utilized.
(2) background technology
Existing Lifting platform all is to adopt the driven by motor screw mandrel to rotate, thereby table top is risen, and as the patent No. is: 99230313.3,02214534.6 utility model patent.99230313.3 utility model patent, motor rose with whole transmission mechanism when desktop rose, and had increased the unstability of table top; 02214534.6 utility model patent, only need a screw mandrel to drive table top and rise, table top is steady in the lifting process, but speed is very slow.
(3) summary of the invention
In order to overcome table top instability in the prior art, the slow-paced deficiency of lifting process, the utility model provides the Lifting platform that a kind of rising or falling speed is fast, table top is stable.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Lifting platform, comprise reversible motor, fixed frame, activity box, be placed in table top, elevating lever, lifting pole socket and transmission mechanism on the activity box, described transmission mechanism is electrically connected with described motor, described activity box is fixed on the elevating lever, it is characterized in that: described transmission mechanism is made up of driving gear, tooth bar, described tooth bar is located on the elevating lever, and described driving gear cooperates with described tooth bar, and described driving gear is located on the fixed frame.
Described transmission mechanism also comprises a driven gear above driving gear, and described driven gear cooperates with described driving gear, tooth bar.
Described motor is a direct current generator.
Described table top is provided with support bar, and described support bar is by the movable rail socket.
Described fixed frame is provided with stroke rising limit switch and decline limit switch, and described activity box is provided with limit switch and touches slide block.
Described table top below is provided with the anti-microswitch of pressing.
Described movable rail segmentation is formed.
The beneficial effect of a kind of Lifting platform described in the utility model mainly shows: 1, adopted a toothed rack " stair type transmission ", rising or falling speed is fast; 2, motor and driven wheel are fixed on the fixed frame, can not rise with desktop, thus stable drive when table top rises, the whole center of gravity in back that rises can be too not high and not steady when causing table top to use.
(4) description of drawings
Fig. 1 is a kind of Lifting platform sectional axonometric drawing of the utility model.
Fig. 2 is a kind of Lifting platform track structure of the utility model schematic diagram.
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Lifting platform as shown in Figure 1 and Figure 2, comprise table top 1, direct current generator 2, fixed frame 3, activity box 4, transformer 5, driving gear 6, driven gear 7, tooth bar 8, table top 1 is fixed on the activity box 4, direct current generator 2, transformer 5 are fixed on the fixed frame 3, table top 1 is provided with lifting sliding rail three joint rails 9, driving gear 6 and driven gear 7 engagements, driven gear 7 cooperates with tooth bar 8, and tooth bar 8 is rigidly connected by rack combination part 16 and activity box 4.The lifting pole socket is made up of clamp bar 10 and stationary rack lid 11, prevents tooth bar 8 derailings.
Fixed frame 3 is provided with stroke rising limit switch 12 and decline limit switch 13, and activity box 4 is provided with limit switch and touches slide block 14.
The just commentaries on classics counter-rotating of the switch control direct current generator 2 that five core plugs 17 of transformer are drawn.When direct current generator 2 energisings were just being changeed, driving gear 6 drove driven gear 7 pinion racks, the 8 whole activity box 4 of drive and table top 1 rises along lifting sliding rail 9.When rising to setting height, limit switch touches slide block 14 and touches rising limit switch 12, and circuit disconnects, and table top is parked on the setting height.
During direct current generator 2 energising counter-rotatings, operation principle is the same, and stroke is opposite, gear 8 counter-rotatings, and activity box 4 and table top 1 descend.When dropping to setting height, limit switch touches slide block 14 and touches decline limit switch 13, and circuit disconnects, and table top is parked on the setting height.
Table top 1 below is provided with four anti-microswitches 15 of pressing, and when snapping into human body accidentally, upsprings by rack combination part 16, and the direct current generator outage stops transmission.After human body left, table top recovered steadily, the microswitch conducting, and direct current generator continues the beginning operate as normal.
Claims (7)
1, a kind of Lifting platform, comprise reversible motor, fixed frame, activity box, be placed in table top, elevating lever, lifting pole socket and transmission mechanism on the activity box, described transmission mechanism is electrically connected with described motor, described activity box is fixed on the elevating lever, it is characterized in that: described transmission mechanism is made up of driving gear, tooth bar, described tooth bar is located on the elevating lever, and described driving gear cooperates with described tooth bar, and described driving gear is located on the fixed frame.
2, Lifting platform according to claim 1 is characterized in that: described transmission mechanism also comprises a driven gear above driving gear, and described driven gear cooperates with described driving gear, tooth bar.
