Abstract

The utility model discloses a screen enlarger, which is composed of an enlarging device part 1 and a supporting device part 2. The screen enlarger utilizes the principle that a magnifier can magnify objects. A main component is composed of a large convex lens type cavity; when the cavity is filled with a certain transparent liquid such as water from a liquid adding mouth 3 at upper end, a large convex lens is formed to play the enlarging effect. When the screen enlarger is arranged in front of a screen of a TV or a computer, etc., the observed screen image is greatly larger than the actual screen. When the screen enlarger is required to move position, only a valve 5 is opened; then the liquid automatically flows out from a liquid discharging mouth 4 at lower end, and is discharged to a designated container; after the position is fixed, the liquid is refilled in.

Description

Screen magnifier

The utility model relates to a kind of screen magnifier.

Present common on the market magnifier such as Fig. 1, it often is used as instruments used for education, the imaging of research lens, or read when some have than the data of small font such as map etc. and use, for bigger object such as computer, the screen of TV etc., only can locally amplify, do not reach whole effect of amplifying.

The purpose of this utility model is in order to overcome above-mentioned existing shortcoming, provide a kind of can be with big object such as computer, the whole amplifier that amplifies such as the screen of TV etc.

The utility model is made of multiplying arrangement part 1 and bracing or strutting arrangement part 2, multiplying arrangement 1 is that the protruding shape cavity of hard transparent material constitutes by a shell, when when wherein filling with certain transparency liquid such as water, then constitute a big magnifier, amplification effect is equal to magnifier shown in Figure 4.Before the utility model being placed the screen of computer or television, then play the effect that integral image is amplified.When will mobile the utility model, the liquid in the amplifier can be discharged in the predetermined container, move so comparatively light, treat that the position is retightened after, liquid is added again, can recover amplification effect.

The screen magnifier of Zhi Zaoing can play screen amplification effect preferably in this way, thereby makes less screen visually become bigger screen.

Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:

Fig. 1 is a common magnifier, and wherein 1 is enlarging lens, the 2nd, and handle.Fig. 2 is a large-scale convex lens sheet, and it is with the enlarging lens among Fig. 11 result amplified by a certain percentage.Fig. 3 is the left view of enlarging lens shown in Figure 2.Fig. 4 is the middle part of magnifier intercepting shown in Figure 2.Fig. 5 is an outside drawing of the present utility model, in Fig. 5, the 1st, multiplying arrangement, its functional equivalent is in enlarging lens shown in Figure 4, different is that multiplying arrangement is the protruding type cavity of being made by hard transparent material, and a filling opening 3 is arranged on it, when in cavity, filling with certain transparency liquid such as water from here, then play the amplification effect the same with eyeglass shown in Figure 4.

In Fig. 5, the 2nd, bracing or strutting arrangement is leakage fluid drams in order to support multiplying arrangement 1.4 of the present utility model, when the utility model needs the shift position, can open valve 5, then liquid is entered in the preprepared container, after retightening good position, liquid is got final product from 3 addings of upper end filling opening.Fig. 6 is a common televisor, the utility model of shape such as Fig. 5 is placed the dead ahead of TV screen, then the screen picture of being seen is more much bigger than real image, and certainly, multiplying arrangement part 1 of the present utility model also can be directly be made of the enlarging lens of similar Fig. 4.

Claims

(1). a kind of screen magnifier, constitute by multiplying arrangement part 1 and bracing or strutting arrangement part 2, it is characterized in that multiplying arrangement part 1 is made of interior protruding shape cavity or the monoblock transparent material that fills transparency liquid, bracing or strutting arrangement 2 is used for supporting multiplying arrangement 1.
(2). according to the screen magnifier of claim 1, the shell that it is characterized in that above-mentioned protruding shape cavity is made of hard transparent material such as glass etc., there is a filling opening 3 its upper end, when filling with certain transparency liquid such as water in protruding shape cavity from this hole, then constitutes a big magnifier.
(3). according to the screen magnifier of claim 1, it is characterized in that there is a leakage fluid dram 4 lower end of protruding shape cavity, when wanting discharged liquid, open valve 5, then liquid flows out automatically.
