Technical field
This utility model is related to a kind of elevating mechanism, more particularly to a kind of three-level lifting column mechanism.
Background technology
Existing three-level lifting column class product on the market, primary structure is usually worm screw and adds travel switch, and passes through one
Individual Motor drive worm screw realizes lifting.Column size is less to be generally used for the lighter object of load-bearing, for example：Television set lifts
Platform, in 50KG, rising or falling speed is usually 6-7mm/S for load-bearing.But for being applied to the three-level elevating mechanism of Beauty bed, then
Need column size larger, and generally adopt two three-level columns to carry the weight of bed（More than 175KG load-bearing）, lifting
Speed is usually 3-3.5 mm/S, and rising or falling speed is just unable to reach load-bearing requirements sooner, and is typically only capable to the second level and has risen
Bi Hou, restarts the third level and rises, decline is also such.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model be to provide a kind of can fast lifting three-level lifting
Column agency.
This utility model is to solve its technical problem employed technical scheme comprise that：
A kind of three-level lifting column mechanism, the one-level column including underframe and being arranged on underframe, two grades of columns, three-levels are stood
Post, described one-level column, two grades of columns, three-level columns are flexibly connected successively, also include for driving the two of two grades of column up-downs
Level lifting push rod, the three-level lifting push rod for driving three-level column up-down, described secondary lifting push rod has also driven one can rise
The middle plate of fall, the bottom that described three-level lifts push rod is connected on middle plate.
Further, described middle plate is fixedly connected with a portal frame, the top of described secondary lifting push rod pass through middle plate with
Gantry top of the trellis is fixedly connected, and passes through portal frame band disorder of internal organs plate and two grades of column synchronization liftings.
Further, described middle plate is fixedly installed on two grades of column bottom, described portal frame bottom pass through trip bolt with
Plate is fixedly connected.
Further, described one-level column, two grades of columns, three-level column be internally formed hollow structure, described two grades rise
Fall push rod, three-level lifting push rod, middle plate, portal frame are arranged in described hollow structure.
Further, the bottom of described secondary lifting push rod is connected on underframe.
Further, the top of described three-level column is provided with top board, and the top that described three-level lifts push rod is fixed with top board
Connect.
Further, described middle plate has a perforation, in described perforation, be provided with push rod cord channel, described push rod power supply
The bottom of line passage is fixedly connected with underframe, and described middle plate can lift along push rod cord channel.
The beneficial effects of the utility model are：Three-level lifting column mechanism of the present utility model, secondary lifting push rod and three
Level lifting push rod can separately lift, and also can lift simultaneously.When secondary lifting push rod and three-level lifting push rod lift simultaneously, three
The rising or falling speed of level column is the speed addition that secondary lifting push rod and three-level lift push rod, thus can greatly speed up three-level column
Rising or falling speed.Additionally, the supporting power of this three-level lifting column mechanism is greatly improved, single three-level lifting column mechanism can
Carry more than 175KG weight.
Brief description
Fig. 1 is sectional structure chart of the present utility model.
In figure label represents：1- underframe；2- one-level column；Bis- grades of columns of 3-；4- three-level column；5- secondary lifting push rod；
6- three-level lifts push rod；Plate in 7-；8- portal frame；9- top board；10- push rod cord channel.
Specific embodiment
Below in conjunction with accompanying drawing and example, this utility model is described further.
With reference to Fig. 1, a kind of three-level lifting column mechanism of the present utility model, including underframe 1 and be arranged on underframe 1 one
Level column 2, two grades of columns 3, three-level columns 4, described one-level column 2, two grades of columns 3, three-level columns 4 are flexibly connected successively, also
Including for driving the secondary lifting push rod 5 of two grades of column 3 liftings, the three-level lifting push rod for driving three-level column 4 lifting
6.
Described secondary lifting push rod 5 also drives a liftable middle plate 7, and described middle plate 7 is fixedly connected with a setting
Portal frame 8.The bottom of described secondary lifting push rod 5 is connected on underframe 1, and top is fixed through middle plate 7 with portal frame 8 top
Connect, and disorder of internal organs plate 7 and two grades of column 3 synchronization liftings are carried by portal frame 8.Specifically, described middle plate 7 is fixedly installed on two grades
Column 3 bottom, described portal frame 8 bottom is fixedly connected with middle plate 7 by trip bolt.
The top of described three-level column 4 is provided with top board 9, and the bottom that described three-level lifts push rod 6 is connected on middle plate 7,
Top connects top board 9.
One perforation is had on described middle plate 7, in described perforation, is provided with push rod cord channel 10, described push rod power line leads to
The bottom in road 10 is fixedly connected with underframe 1, and described middle plate 7 can lift along push rod cord channel 10.
Described 2, two grades of columns 3 of one-level column, three-level column 4 be internally formed hollow structure, described secondary lifting pushes away
