Description

A kind of Portable video display stand for teaching

Technical field

This utility model belongs to teaching equipment technical field, particularly relates to a kind of video showing platform.

Background technology

Scanner in the market presses the difference of photo-electric conversion element, generally CCDChargeCoupledDevice, light electric coupling induction apparatus scanner.It is by, in lens focus to CCD, converting optical signals into signal of telecommunication imaging, and the latter is close to scan contribution surface and carries out the scanning of contact.Ccd scanner to direct exposure on CCD, can carry out scanning in kind by lens focus very easily.In scanner, sensor devices CCD is the technology of a kind of comparative maturity, and its cost is relatively low, and image quality is more and more higher, and some even can compare favourably with the photomultiplier tube of use in rotating drum image scanner, has high cost performance.Using the CCD of silicon single crystal technology relatively low to the requirement of ambient temperature, the scope of adaptation is wider.Development along with technology, the most also a kind of video presenter is occurred in that at present, video presenter is also known as article showing platform, when it is connected on scialyscope and television set, just data, teaching materials, material object, lantern slide etc. clearly can be displayed, be one of indispensable teaching equipment of multi-media classroom.The video showing platform that one Daepori is logical includes three parts: photographic head, light source and table top, also have a series of interface at the show stand back side, and some also include the adnexaes such as infrared remote controller, computer picture capture adapter, LCD monitor towards the show stand of high-end market.Video showing platform can be applied in each course teaching: literal arts class can be imparted knowledge to students various resources material to use the various books space of a whole page, be placed directly within show stand table top, by the application of light, the adjustment of enlarging function, it is possible to clearly show；Chemistry, physics subject can directly carry out some experiments on show stand, allow each student's clear view；Biological, medical science subject can observe, by the adapted (microscope is first-class) of show stand camera lens, the image that material object amplifies.Supporting the use with output, input equipments such as multimedia projector, large screen back projection TV, general television set, LCD monitor, videocorder, VCD, DVD player, microphones, video showing platform has widely purposes in information technology teaching again.Teacher only just can need to conveniently carry out document display by dragging with hands up and down about document.The most existing video showing platform inconvenient operation, the horizontal strut part of chain-drive section is the most sagging or upwarps, and structure is the most complex.

Utility model content

In view of the above-mentioned problems in the prior art, main purpose of the present utility model is to solve the defect of prior art, it is provided that a kind of Portable video display stand for teaching, and its simple in construction is easy to use, and has more preferable imaging effect.

The technical solution adopted in the utility model is as follows:

A kind of Portable video display stand for teaching, including the base with backlight, base is provided with the control station being built-in with rechargable power supplies, and control station is fixed with can the desk lamp neck of torsional bending, desk lamp neck is fixed with head by support, and the end of head is provided with CCD camera lens；The both sides of control station are additionally provided with the light compensating lamp with desk lamp neck.

Further, control station is provided with front panel, and front panel is provided with power button and at least one function key.

Further, under use state, the CCD camera lens of head end is towards backlight.

Further, the weight of base is more than head and the weight sum of light compensating lamp.

Further, the bottommost of base is provided with for anti-skidding non-slipping block.

In sum, compared with prior art, the beneficial effects of the utility model are:

This utility model have employed desk lamp neck, instead of, with desk lamp neck, the purpose that complicated frame for movement reaches flexible so that this utility model is the simplest compared to other like product structures；The employing of CCD camera lens, also makes this utility model be provided with more preferable imaging effect；And the most built-in rechargable power supplies of this utility model, when teaching, the longest line just need not be connect, this is very easy to the use imparted knowledge to students.

Accompanying drawing explanation

This utility model will illustrate by example and with reference to the appended drawing, wherein:

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

All features disclosed in this specification, or disclosed all methods or during step, in addition to mutually exclusive feature and/or step, all can combine by any way.

As shown in Figure 1: a kind of Portable video display stand for teaching of the present embodiment, including the base 1 with backlight 2, base 1 is provided with the control station 3 being built-in with rechargable power supplies, control station 3 is provided with front panel and rear board, front panel is provided with power button 10 and at least one function key 11(for controlling operation, work such as CCD camera lens 6), the both sides of front panel are additionally provided with USB interface 9；The power interface for charging it is additionally provided with on rear board；Be fixed with on control station 3 can the desk lamp neck 4 of torsional bending, desk lamp neck 4 is fixed with head 5 by support 8, and under use state, the CCD camera lens 6 of head 5 end is towards backlight 2, and CCD camera lens 6 is parallel with backlight 2；The end of head 5 is provided with CCD camera lens 6；The both sides of control station 3 are additionally provided with the light compensating lamp 7 with desk lamp neck 4, use LED light supplement lamp in the present embodiment, and it has the characteristics such as light efficiency high-low voltage, volume is little, life-span length, fast response time, shock resistance strong, energy-saving and environmental protection；In order to make this device more securely to place, the present embodiment adds counterweight iron block in base 1 so that the weight of base 1 is more than head 5 and the weight sum of light compensating lamp 7, simultaneously, bottommost at base 1 is provided with for anti-skidding non-slipping block again, and this non-slipping block uses the rubber blanket with fold.

CCD camera lens 6: compared to CMOS camera lens, its imaging effect is more preferable；The semi-conducting material of its a kind of ISO of use of CCD is made, light can be transformed into electric charge, it is converted into digital signal by analog-digital converter chip, digital signal is preserved by the flash memory of camera internal or built-in hard disk card after overcompression, thus easily data can be transferred to computer, and by means of the process means of computer, revise image with imagination as required.CCD is made up of, generally in units of mega pixel many photosensitive units.When CCD surface is irradiated by light, electric charge can be reflected on assembly by each photosensitive unit, and signal produced by all of photosensitive unit is added together, and just constitutes the picture that a width is complete.

From such scheme it can be seen that this utility model have employed desk lamp neck, instead of, with desk lamp neck, the purpose that complicated frame for movement reaches flexible so that this utility model is the simplest compared to other like product structures；And the most built-in rechargable power supplies of this utility model, when teaching, the longest line just need not be connect, this is very easy to the use imparted knowledge to students.

Description of the present utility model and application are illustrative, are not wishing to limit in the above-described embodiments scope of the present utility model.The deformation of embodiments disclosed herein and change are possible, and for those skilled in the art, embodiment is replaced and the various parts of equivalence are known.It should be appreciated by the person skilled in the art that in the case of without departing from spirit or essential characteristics of the present utility model, this utility model can otherwise, structure, layout, ratio, and realize with other elements, material and parts.
