A kind of flexible grid type liquid crystal display lift
The present invention relates to display screen auxiliary equipment field, specifically a kind of flexible grid type liquid crystal display lift.
Development and release market with present various intelligent artifacts, video conference and the use of computer are even more frequent, its
Middle liquid crystal screen lifting machine provides convenient, it is necessary to during using display screen, be hidden in conference table to the use and video conference of computer
Display screen is raised to table surface from below conference table by internal lift, and when display screen is not used, lift declines automatically,
Display screen is hidden in inside conference table, antitheft, dust-proof, keeps the smooth and attractive in appearance of table surface.The jacking system can meet
The need for display is without dismantling and avoiding haphazardly to connect up, the space below desktop is made full use of, main frame and display
Be hidden in simultaneously under table, it is necessary to when can when needing to use trigger controller, Cang Gai automatically opens up, and display rises to desktop,
Display screen liter comes up, not the used time be recoverable to table bottom again, be satisfied with the requirement of different participants.
Liquid crystal screen lifting machine is various informative, but the cabinet for being used all is similar, and current liquid crystal screen lifting machine cabinet is high
Degree is non-adjustable, according to the liquid crystal screen lifting machine cabinet of the highly desirable apolegamy different model of different desk bodies, or uses model less than normal
, but mostly after the installation of model less than normal is to be suspended from desk body lower section, increased the load-bearing of desk body；Existing liquid crystal display lifting simultaneously
It is slow that the Cang Gai of rack body opens and closes speed；In addition, hydraulic lifting or electric up-down are used current lift more,
Rising or falling speed is fast, stability is poor, DeGrain of weighing, while hydraulic pressure easily causes liquid leakage, and treatment is inconvenient；In consideration of it,
The invention provides a kind of flexible grid type liquid crystal display lift.

Up to desktop；After using finishing, the counter motion of two receivers 114 is driven by the contractile motion of electric pushrod 113, and simultaneously
Because the bottom of electric pushrod 113 is connected with mobile sliding block 112, so electric pushrod 113 can while contractile motion is carried out
The function that realization is moved downward；Under the drive of receiver 114, expansion link 124 can carry out upper and lower ends contractile motion, and due to
Mounting hole II on the top of expansion link 124 and upper footstock 122 and concurrent between the side of the upper end of double leval jib 127, so four connect
Bar 127 can carry out being realized outwardly against motion the descending motion of fixed seat 123；When liquid crystal display all drops in cabinet 2
When, storehouse lid 241 is then driven with turning joint 242 by the stretching routine of the first shrinking connecting-rod 243 and the second shrinking connecting-rod 246
For rotary shaft is rotated clockwise, the closing function of storehouse lid 241 is realized.
