Bottom plate 220 is vertically fixedly connected.Two of top plate 210 are respectively arranged with guide sleeve 211 and guide sleeve 221, bottom by the position of close end
Two of plate 220 are respectively arranged with guide sleeve 212 and guide sleeve 222 by the position of close end, and the axial direction of four guide sleeves is in same flat
Face, parallel to each other and vertical with the upper surface of top plate 210, i.e. four guide sleeves are axially parallel to direction A.In some embodiments
In, the quantity of guide sleeve and setting position are not limited to the present embodiment, according to the actual situation depending on.
In some embodiments, the pedestal 20 further includes being fixedly connected on the limited block 240 of 210 upper surface of top plate and consolidating
Surely it is connected to the limited block 250 of 220 lower surface of bottom plate.As shown in Figure 1, in the present embodiment, being fixedly connected on table on top plate 210
First limited block 240 in face is column type limited block, limits for the decline to lifting unit 40, prevents lifting unit 40 from existing
Top plate 210 is directly hit during decline.The second limited block 250 for being fixedly connected on 220 lower surface of bottom plate is T-type limited block,
It is limited for the rising to lifting unit 40, lifting unit 40 is prevented to be detached from pedestal 20 in uphill process.In other realities
Apply in example, the quantity of the limited block 240 and limited block 250, shape and fixed position will according to the actual situation depending on, not
It is limited to the present embodiment.
In some embodiments, driving unit 30 includes driver 310, brake 320 and rotatable parts 330.Driving
Unit 30 is used to provide power, deceleration and positioning action to lifting unit 40.As shown in Figures 2 and 3, in the present embodiment, it drives
Dynamic device 310 is motor, and brake 320 is retarder, and rotatable parts 330 are gear.Driver 310 is used to generate driving torque,
Power is provided for lifting body 10；Brake 320 is fixed on 220 side of top plate 210 and bottom plate, and is located at driver 310 and turns
Between dynamic component 330, for matching the output torque of driver 310 and transmitting torque to rotatable parts 330；Rotatable parts
330 are set to the output end of brake 320, fixed-axis rotation are done under the output action of brake 320, and rotatable parts 330 are stretched
Enter between bottom plate 220 and top plate 210, while being meshed with the transmission parts in lifting unit 40, and then is passed to lifting unit 40
Graduating power.In some embodiments, the rotatable parts 330 are not limited to gear, can have the component of rotary action for other.
In some embodiments, lifting unit 40 includes lifter plate 410, rack gear 420 and guide rod 430.As shown in Fig. 2,
In the present embodiment, the quantity of the rack gear 420 and guide rod 430 is one.In addition, in the present embodiment, the rack gear 420 is circle
Rack gear.In some embodiments, 420 side's of being rack gear of rack gear or other can play the rack gear of transmission effect.The rack gear 420 with
Rotatable parts 330 are meshed.Rack gear 420 and 430 length of guide rod are identical, parallel to each other and vertical with 410 bottom of lifter plate solid
Fixed connection.Rack gear 420 passes through the guide sleeve 211 and guide sleeve 212 in pedestal 20, and guide rod 430 passes through the guide sleeve 221 in pedestal 20 and leads
Set 222.Guide sleeve 211 and guide sleeve 212 and rack gear 420 and guide sleeve 221 and guide sleeve 222 and guide rod 430 suitably pairing, avoid
Guide sleeve internal diameter is narrow, generates biggish frictional influence to rack gear 420 and guide rod 430 and goes up and down performance, while also avoiding guide sleeve internal diameter
It is wide, rack gear 420 and guide rod 430 suitably pairing can not be led to not accurately be oriented to guide rod.That is rack gear 420 and guide rod
430 secure the direction of motion by four guide sleeves in pedestal, and the movement of rack gear 420 and guide rod 430 will be along the axis of four guide sleeves
It is moved to direction A, therefore rack gear 420 and guide rod 430 have guide function.
Since rack gear 420 and guide rod 430 are fixedly connected with lifter plate 410, rack gear 420 is rotated in rotatable parts 330 to be driven
Under movement lifter plate 410 and guide rod 430 same will be driven to do synchronization lifting, i.e. rack gear 420 has transmission agency.In addition, work
Part is placed in 410 top of lifter plate, as the lifting of lifting unit 40 moves synchronously.
Since rack gear 420 has both transmission agency and guide function, the quantity of guide rod is reduced, the weight of lifting unit 40
It reducing therewith, the abrasion between rack gear 420 and rotatable parts 330 can also be reduced with the reduction of the weight of lifting unit 40,
I.e. so that the performance of lifting body 10 improves, while reducing cost and maintenance difficulties.
In some embodiments, the quantity and shape of the rack gear 420 and the guide rod 430 are not limited to this implementation
Example.It is considered as in different situations, there is the feature of transmission and guide function to rack gear 420 simultaneously using rack gear 420 and lead
The quantity of bar 430 is adjusted, to reach to integrally-built optimization.
When the torque that brake 320 will be transmitted to rotatable parts 330 reduces, 330 revolving speed of rotatable parts reduces, and then makes
The deceleration of motion of rack gear 420.When brake 320 stops providing torque to rotatable parts 330, rotatable parts 330 stop rotating,
Make 420 stop motion of rack gear, i.e. driving unit 30 can control the stop position of rack gear 420, to carry out to lifting unit 40
Positioning.
As depicted in figs. 1 and 2, in the present embodiment, the bottom position of rack gear 420 is provided with third limited block 421, third
Limited block is U-shaped limited block, for cooperating the second limited block 250 to limit the rising of rack gear 420.Second limited block 250
T-type structure can prevent the bottom end of rack gear 420 from passing through guide sleeve 212 with the U-shaped mechanism of third limited block 421 pairing well,
The rising of lifting unit 40 can be limited, prevent the bottom end of lifting unit 40 from passing through the bottom plate 220 of pedestal 20.One
In a little embodiments, quantity, shape and the fixed position of the limited block 421 will according to the actual situation depending on, however it is not limited to this
Embodiment.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
A kind of embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
