Described elevating motor is two, and each drives a sets of transmission mechanism.
Described driving mechanism mainly is made up of chain, upper sprocket wheel, spindle sprocket, tensioner sprocket wheel and driving sprocket wheel, and wherein, driving sprocket wheel is connected with elevating motor.
Also be fixed with decoration panel around the described cabinet top, and through switching mechanism be connected with can closed cabinet outlet roll-over panels, elevating motor connects and also drives switching mechanism.
The display screen deflection mechanism of display screen yaw motor and driving thereof also is installed on the described lifting frame, and the display screen yaw motor connects and is controlled by control circuit board.
Described lifting frame comprises the up-down panel of fixed connection and the support under the panel.
Described control circuit board is fixed on the cabinet bottom, and water bar is installed above control circuit board.
Described elevating motor adopts autosynchronous motor.
After adopting such structure; The utility model desktop liquid crystal display screen lifting machine; It is just passable only need to open a square hole in the position that conference table need be installed display screen, and therefore installation is very simple, and it is little to take the area of conference table; Can not destroy the structure of conference table, be more suitable for extensively promoting the use of.
Description of drawings
Above-mentioned only is the general introduction of the utility model technological scheme, in order more to know the technological means of understanding the utility model, below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model desktop liquid crystal display screen lifting machine.
Embodiment
See also shown in Figure 1ly, the utility model desktop liquid crystal display screen lifting machine mainly comprises cabinet 1, lifting frame 2, elevating motor 3 and control circuit board 4.
Wherein, cabinet 1 is the carrier of entire equipment, and other parts all can be installed on the cabinet through screw.Cabinet 1 can be spirally connected by mainframe, left and right sides liner plate, left and right sides cover plate and large cover etc. and form, and also can be fixed with aluminum alloy decoration panel 11 through screw around the top, and connects the aluminum alloy roll-over panels 13 that can closed cabinet 1 exports through switching mechanism 12.
After decoration panel 11 is installing of the utility model with roll-over panels 13, the unique device side that can see of client, its surface all can adopt technologies such as wire drawing, oxidation blackout to decorate.When liquid crystal screen rose, roll-over panels 13 was opened under the drive of driving mechanism 31 and switching mechanism 12, and liquid crystal screen is able to rise from smoothly desktop; Liquid crystal screen is fallen and when being hidden in desktop, the upper outlet of roll-over panels 13 closed cabinets 1 when playing the beautiful decoration effect, can prevent that also foreign matter from dropping in the equipment.
Lifting frame 2 is installation carriers of display screen, can be made up of aluminium alloy panel of fixing through screw 21 and the support 22 under the panel, and above aluminium alloy panel 21, be provided with mounting structure for display screen 23.The surface of aluminium alloy panel 21 can adopt technologies such as wire drawing, oxidation blackout to decorate equally, and it mainly acts on is to fill the hole that stays after roll-over panels 13 is hidden, and mainly plays and decorates and prevent the effect that foreign matter is fallen into.
Preferable, the display screen deflection mechanism 25 that display screen yaw motor 24 also can be installed on the lifting frame 2 and drive, display screen yaw motor 24 together is connected and is controlled by control circuit board 4 with elevating motor 3.Display screen yaw motor 24 is power sources of entire display screen deflection, is fixed on the lifting frame through screw.Through the forward and backward of control circuit board 4 control display screen yaw motor 24, thereby drive display screen deflection mechanism 25, make display device deflection several angle.
