Description
Technical field
The invention belongs to display base technical fields, and in particular to a kind of for hanging the desktop electric up-down of display
Pedestal.
Background technique
As tabletop display is in the extensive use of every field and scene, its suspension arrangement also proposed more and more
Requirement.The base device of suspension display is largely unadjustable height at present, and due to user's individual stature
Difference and different use occasions requirement, the display height of display should be that cooperation is adjustable, especially for a long time improperly
Height of display can cause the sufferers such as visual impairment, cervical spondylosis, lumbar vertebra disease to user, therefore adjustable display height is outstanding
Hang device is very necessary.
Traditional hand-operated lifting pedestal needs adjust height by artificially lifting and press display, operate convenience compared with
Difference, low precision, adjustment speed is unstable, and the display of other fixed not compatible weight of counterweight.
Device currently used for adjusting desktop height of display is mainly that table top lifting device has no lifting pedestal correlation dress
It sets, Chinese patent " a kind of electronic noiseless the table top lifting device " (patent No.: 201720358005.0) and Chinese patent " desktop
Self-powered platform " (patent No.: 201620882811.3) individually disclosing a kind of electric up-down desktop and hand-operated lifting desktop, can
To be used for placement display, respectively by the way that electronic, manually mode adjusts the height of the Level Change display of desktop, however this
Kind mode cannot be considered in terms of suitable height of table top while meeting height of display, can not solve the problems, such as at all；It is Chinese special
A kind of liquid crystal display electricity is disclosed in sharp " a kind of LCD electric lifting pedestal " (patent No. 201420605561.X)
Dynamic lifting pedestal cooperates key to realize electric up-down by stepper motor, but the lifting pedestal does not have adjustment pitch angle
With the function of horizontal rotation angle, the position of limit switch can not be adjusted according to different displays, may result in display
The too low shock bottom in device position, or phenomena such as because of excessively high run-off the straight, and do not have speed regulation function, for different weight
Display be unable to satisfy user and more require.
Summary of the invention
In order to overcome the deficiencies of the prior art, the present invention is directed at least solve one of prior art problem, one kind is provided and is used for
The desktop electric up-down pedestal of display is hung, height of display and adjustable feathering angle can be controlled with motorized adjustment
Degree and pitch angle.
The present invention is achieved through the following technical solutions: it is a kind of for hanging the desktop electric up-down pedestal of display, it wraps
Include chassis, lower pillar stand, upper pillar stand, control module, electric up-down push rod, swivel hinge mechanism, pitching linkage and display
Fixed disk；The lower pillar stand plays a supportive role with chassis fixation；Electric up-down push rod bottom is fixed with chassis；It is described vertical
The top fixation of column top and electric up-down push rod can be with electric pushrod lifting carriage；The control module is fixed in chassis
Portion is connected with electric up-down pedestal and lifter switch, and the key and power interface in control module are arranged on chassis；The rotation

Fixed disk is fixed on above pitching linkage for hanging display.
The present invention may be implemented stablizing for tabletop display and go up and down, and it is uncontrollable to solve conventional desktop height of display
Drawback improves the applicability that display is directed to different scenes, it is often more important that also adjustable while adjustable height
Pitching and level angle are effectively eliminated since inappropriate display height and angle are sick to user's bring spondylodynia etc.
Suffer from.
Preferably, plastic sleeve is fixed with above the lower pillar stand；It is flanked outside the upper pillar stand inner wall and plastic sleeve
Touching.
Plastic sleeve is arranged in this programme between upper pillar stand and lower pillar stand, avoids avoiding upper pillar stand under in lifting process
Column direct friction but using plastics as contact material, noise can be eliminated, and the more stable lifting of upper pillar stand can be made, extend rise
The service life of pedestal drops.
Preferably, bracket is further fixed on the chassis；Upper and lower two limit switches are fixed on bracket, at the top of gag lever post
It is fixed at the top of upper pillar stand, gag lever post bottom is placed between limit switch up and down and is arranged in a linear, and gag lever post is moved with upper pillar stand
Process can touch limit switch.
It is highly preferred that limiting the motion range of lifting pedestal by changing the fixed position of upper lower switch, stroke is made to exist
It is adjustable in 10~400mm.
Due to the difference of display sizes, adjusting too low can make display bottom touch desktop and excessively high can make display
The excessively high influence structural stability of center of gravity, the present invention is preferably provided with gag lever post and limit switch, and gag lever post is moved through with upper pillar stand
Journey can touch limit switch to stop current kinetic, can limit lifting pedestal by changing the fixed position of upper lower switch
Motion range is to be adapted to different displays.
Preferably, limit switch is connected with control module, is led to by the triggering control to limit switch to output electric current
It is disconnected.
Preferably, the thrust limit of the electric up-down push rod is 1000N, and the adjustable range of height is 0~400mm.This
The preferred electric up-down push rod of scheme meets most desktop display demands.
Preferably, the control module provides pwm signal for electric up-down push rod, changes input signal by control module
Duty ratio, to realize the adjusting of electric up-down push rod speed, speed includes 5,10,15,20,25,30,35,40,45 and
Ten gears of 50mm/s.
It is highly preferred that the control circuit of pressing control module be equipped with upper and lower two lifting keys and plus, the speed that subtracts two
Regulating key, and key is arranged at chassis, changes sense of current by the upper and lower key in pressing control module to realize
The lifting of electric up-down push rod is added by the speed in pressing control module, subtracts key to change the duty ratio of signal, thus real
Now to the adjusting of electric up-down push rod speed.The lifting pedestal of this programme is more convenient user's operation, and user can be according to difference
Demand lifting speed is adjusted by key.
Preferably, the swivel hinge mechanism realizes that the rotation in -90 °~90 ° sections is adjusted by internal damp hinge.
Preferably, pitching linkage realizes the pitch regulation in 0~45 ° of section by internal damp hinge.
Level angle in above range is adjusted and pitch angle adjusts the use demand that can meet most scenes.
Preferably, the power interface of control module is arranged on rear side of chassis, is used for power input.Socket on rear side of chassis both
It can guarantee safety, prevent from touching, it is also more neat and artistic.
The opposite and prior art, the invention has the following advantages that
(1) height of display is controlled using Motorized lift device, it is easy to operate, and adjustable pitching and level angle,
It effectively eliminates due to inappropriate display height with angle to sufferers such as user's bring spondylodynias；
(2) lifting pedestal of the invention solves traditional manual adjustment base poor controllability, and stability is poor and can operate
Property it is poor the defects of, have many advantages, such as that lifting is steady and noise is small, provide good operating experience for user；
