The content of the invention
It is an object of the invention to provide a kind of elevating type multifunctional to support computer rack, to solve middle and primary schools in the prior artThe problem of computer is highly single in teaching process, realize the flexible purpose being adjusted to computer for students.
The present invention is achieved through the following technical solutions：
A kind of elevating type multifunctional supports computer rack, including base, and it is first flexible that several are fixedly connected with the baseBar, the axis of first expansion link are hinged under loading plate perpendicular to susceptor surface, the top of all first expansion linksSurface, the bottom of the loading plate set drawer appliance；Also include the second expansion link being arranged on loading plate, the second expansion linkIt is fixed on the posterior edges of loading plate, the top of second expansion link is fixedly connected with baffle plate, where the baffle plate to loading plateThe projection of plane covers the loading plate；The baffle interior sets power supply, and baffle plate lower surface is embedded lighting device, the power supplyFor power illuminating device.
For computer in middle and primary schools' teaching process in the prior art it is highly single the problem of, the present invention proposes a kind of liftMultifunctional supporting computer rack, base are used to be placed on computer desk to play a supportive role, and it is flexible that some first are fixedly connected with baseBar, loading plate being supported by the first some expansion links, the top of the first expansion link is hinged on the lower surface of loading plate,Therefore can be by adjusting the length of each first expansion link, so as to adjust loading plate to angle of inclination.Back side edge on loading plateEdge fixes the second expansion link, and the effect of carrier bar is to be used to place computer display screen, therefore it deviates from the positive side of display screenIt is rear side, baffle plate is connected by the second expansion link, projection of the baffle plate to plane where loading plate covers the loading plate, beBaffle plate is completely covered by loading plate, is covered using baffle plate above loading plate, so as to be lowered into computer display screenThe probability of dust and other impurities, protection only is being blocked to the computer display screen being placed on loading plate.The present invention is in use, loading plateHeight, angle can be adjusted by the first expansion link, therefore the height of display screen and angle can access regulation so thatUsed suitable for the student of various heights.The height of baffle plate can be adjusted by the second expansion link, therefore can be applied toThe display screen of various height is placed.Powered simultaneously by the power supply illumination apparatus in baffle plate, it is extra in the bad needs of lightTo provide extra lighting apparatus at display screen during illumination, display screen individually shinny injury student's eyes are avoided.Also holding simultaneouslyThe bottom of support plate sets drawer appliance, is easy to students to place article and is stored, greatly improves the feature of the present invention.It is comprehensiveOn, the present invention solves the problems, such as that computer is highly single in middle and primary schools' teaching process in the prior art, realizes flexibleThe purpose being adjusted to computer for students.
Preferably, the quantity of second expansion link is N, and N number of second expansion link is disposed side by side on the back side edge of loading plateEdge, wherein N >=2.Improve to the enabling capabilities of baffle plate, it is ensured that baffle plate is stable to be hidden to the display screen that is placed on loading plateGear protection.
Preferably, the drawer appliance includes framework, slide rail, drawer body, and the framework is fixed on the following table of loading plateFace, framework madial wall set slide rail, and drawer body can enter line slip along the slide rail.Drawer body is arranged in framework,Pull open or close by the way that slide rail progress is flexible, while whole drawer appliance is arranged on loading plate lower surface, can saveSpace, improve the storage ability of the present invention.
Preferably, the loading plate upper surface sets groove.It is easy to the bottom of computer display screen being placed in groove, leads toCross groove and improve computer display screen and be placed on stability when on loading plate.
Preferably, the groove is rounded or square.It is easy to the bottom circular or square with existing display screen to be matched.
Preferably, first expansion link, the second expansion link are electric pushrod, and control first is provided with the baseThe control device of expansion link, the second expansion link.First expansion link, the second expansion link are disposed as electric pushrod, can be easy to controlSystem and operation, while the control device of each electric pushrod is arranged on base by this programme, more facilitates student to be operatedWith use, adjustment difficulty is reduced.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of elevating type multifunctional support computer rack of the present invention, height, the angle of loading plate can be by the first expansion linksIt is adjusted, therefore the height of display screen can access regulation with angle, so as to enter to exercise suitable for the student of various heightsWith.
2nd, a kind of elevating type multifunctional support computer rack of the present invention, the height of baffle plate can be adjusted by the second expansion link,Therefore the display screen that various height can be applied to is placed.
3rd, a kind of elevating type multifunctional support computer rack of the present invention, is powered by the power supply illumination apparatus in baffle plate, in lightLine is bad to be needed to avoid display screen individually shinny injury Eyes of Students during additional illumination to provide extra lighting apparatus at display screenEyeball.Drawer appliance also is set in the bottom of loading plate, is easy to students to place article and is stored, greatly improve the present invention'sFeature.
