Abstract
The utility model relates to a lift platform for podium, including motor (1), rotate through a transmission (2) at motor (1) and connect transverse rotational hinge (3), all connect vertical pivot (5) through the 2nd transmission (4) at transverse rotational hinge's (3) both ends, all coordinate at the both ends of every vertical pivot (5) and connect one lifting devices (6), one backup pad (7) are connected in the cooperation on all lifting devices (6). The utility model discloses an advantage: the dual self -lock device that this device adopted screw nut and worm gear has realized safe location, and its installation is easy, facilitate the use, during the use vibration little, the noise is low, the stable performance, long service life, compact structure, small, light in weight, the maintenance and service of being convenient for, the messenger mr has adjusted teacher's the posture of giving lessons in suitable highly teaching and write the writing on the blackboard, the emergence probability of the occupational disease of reduction.
Description
Technical field
The utility model is related to a kind of instructional device, more particularly to a kind of lifting platform for dais.
Background technology
Teacher is a very by the industry of social respect, and they have offered as a tribute youth of oneself and pungent quietly for the sons and younger brothers that cultivates talent
Industry is dynamic, but long-term hard work usually causes damage to the health of teacher.Traditional classroom platform is level altitude, and different old
The height of teacher is different, therefore when teaching and writing writing on the blackboard, there is certain inconvenience.When teacher writes writing on the blackboard, always using one
Posture, the muscular soft tissues chronic strain around shoulder causes nape part fascitis and shoulder shoulder slip, if do not processed,
Except can it is increasingly severe in addition to, can more develop into cervical vertebra degenerative arthritis or frozen shoulder, cervical vertebra is ached frequently, shoulder when serious,
There is powerlessness, or even headache in back, and arm cannot be raised.And the incorrect stance of long-time can make the deformity of spinal column.Therefore,
Cervical spondylopathy and lumbar disease are especially common in Teaher group.And cervical spondylopathy and lumbar disease are progressive diseases, in work shape
When state can not change, these diseases all can gradually increase, and various treatment means can only relief of symptoms, slow down disease progression.
Utility model content
It is fixed inconvenience that the purpose of this utility model is the height in order to solve classroom platform at this stage, does not apply to difference
The shortcoming that the classroom of height uses, and a kind of lifting platform for dais for proposing.
To achieve these goals, the utility model employs following technical scheme：
A kind of lifting platform for dais, it is characterised in that：Including motor, rotated by the first transmission device in motor
Connect horizontal rotating shaft, longitudinal rotating shaft is connected by the second transmission device at the two ends of horizontal rotating shaft, in rotating shaft longitudinally in each
Two ends are connected a lifting device, and be connected a flat board on all lifting devices.
On the basis of above-mentioned technical proposal, there can be technical scheme further below：
First transmission device is identical with second transmission structures, is driven using intermeshing bevel gear
Group.
The lifting device includes housing, and be connected worm gear and nut in housing, is connected one in worm gear and nut
The individual screw mandrel being vertically arranged, is arranged on hull outside on the upside of screw mandrel, the worm screw engaged with worm gear and nut is additionally provided with housing,
Worm screw correspondence is connected in corresponding longitudinal rotating shaft.
The gripper shoe for supporting the fixation flat board is provided with the upper end of the screw mandrel.
The utility model has the advantage of：This device is realized using feed screw nut and the double self locking device of worm and gear
The positioning of safety, it installs easy, convenient use, vibrates little when using, and noise is low, stable performance, long service life, structure
Compact, small volume is lightweight, is easy to maintenance, teacher is suitably highly being taught and is being write writing on the blackboard, have adjusted
The posture of giving lessons of teacher, the probability of happening of the occupational disease of reduction.
Description of the drawings
Fig. 1 is basic structure schematic diagram of the present utility model；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model dexterously combines machine driving with traditional platform, effectively solves teacher in writing on the blackboard
In teaching, because platform height is not to holding fatigable problem.In order that the utility model becomes more apparent, below in conjunction with accompanying drawing
This device is described in detail, specific embodiment described herein only to explain the utility model, is not used to limit this
Utility model.
As depicted in figs. 1 and 2, a kind of lifting platform for dais that the utility model is provided, including motor 1, in electricity
First connecting rod 14 is connected by first shaft coupling 13 on the output shaft of machine 1, first connecting rod 14 is rotated by the first transmission device 2 and connected
Horizontal rotating shaft 3 is connect, first connecting rod 14 and horizontal rotating shaft 3 are arranged on same level, and are mutually perpendicular, the first transmission device
2 adopt intermeshing bevel gear transmission group, the first transmission device 2 that the rotation direction that motor 1 is exported is changed into 90 degree.
A second connecting rod 16 is connected by a second shaft coupling 15 at the two ends of horizontal rotating shaft 3, each second company
Bar 16 connects longitudinal rotating shaft 5 by second transmission device 4, and longitudinal rotating shaft 5 is arranged on same level with horizontal rotating shaft,
Second transmission device 4 is also adopted by intermeshing bevel gear transmission group, and it is also 90 degree that it rotates conversion angle.
It is connected a lifting device 6 at the two ends of rotating shaft 5 longitudinally in each, the lifting device 6 is included by lower casing
The housing 8 that body and upper shell are connected, be connected the worm gear and nut 9 being vertically arranged in housing 8 by roller bearing, snail
Wheel nut 9 is prior art, and be connected one the screw mandrel 10 being vertically arranged in worm gear and nut 9, and the upside of screw mandrel 10 is arranged
In the outside of housing 8, in the upper end of screw mandrel 10 gripper shoe 12 is connected, in four gripper shoes 12 flat board 7 is connected by screw.In housing
The worm screw 11 engaged with worm gear and nut 9 is additionally provided with 8, worm screw 11 is prior art, and worm screw 11 is fixed by the 3rd shaft coupling 17
It is connected in corresponding longitudinal rotating shaft 5.
This device realizes stable drive, the characteristics of vibration is little, noise is low by the spiral transmission of worm and gear, worm gear
It is linear contact lay between worm geared two-wheeled mesh tooth face, engagement effect more more preferable than crossed helical gears mechanism can be obtained, is driven
Than also higher with bearing capacity.Simultaneously the worm screw lead angle of Worm and worm-wheel gearing is less than engagement wheel between cog equivalent friction angle
When, Worm and worm-wheel gearing will reverse self-locking, at this moment can only be that worm screw drives worm gear, and worm gear cannot drive worm screw, i.e.,
It is capable of achieving the safeguard protection to machinery.
