Abstract
The housing of TV set of band shielding curtain, its shielding curtain can block picture tube and be called cathode ray tube (CRT) or figure orthicon again.This electronic device, when picture tube quit work, extraneous light can not shine on the kinescope screen, and is aging to prevent fluorescent film, increases the service life.Simultaneously, avoided the kinescope screen Outside surface glass to be damaged by implements.
The housing of TV set of this band shielding curtain, can realize its shielding curtain automatically and manual two kinds of on-off modes.Can be extensively as microcomputer, television set, core shells such as all kinds of demonstrations, monitor.
Description
The present invention relates on electric device housings bodies such as television set, install a kind of invention of shielding curtain that can opening and closing.It belongs to a kind of electric device housings.
The housing of TV set of band shielding curtain, its shielding curtain can protect picture tube to be called cathode ray tube (CRT) or this electronic device of figure orthicon again.The housing of TV set of this band shielding curtain can block extraneous light when shielding curtain is closed, make light can not shine kinescope screen, and is aging to prevent the fluorescence film, prolongs its useful life, avoided the kinescope screen Outside surface glass to be damaged by implements simultaneously.Because this class electricity equipment of television set is difficult for frequent opening and closing; in order to reduce the switch number of times in the short time; so that eyes are not overtired when watching the image time longer; can use the way of closing shielding curtain, block the picture tube image, and X ray; make eyes obtain having a rest; be beneficial to protect eye eyesight, this point more demonstrates the superior of shielding curtain for the computer operation personnel.
The present television set that uses, microcomputer, various show look, monitor etc.Picture tube on these equipment when equipment does not use, all at casing overcoat one enclosure, or covers a shelter, with the protection kinescope screen.This at casing overcoat one enclosure, or the method for covering shelter exists its defective to be:
One, must take off coverings such as the enclosure before electric equipment uses, the covering that takes off need have the place of depositing.
When two, electric equipment task time is longer, just cover coverings such as the enclosure after the shutdown, equipment is difficult for heat radiation.
Three, get troublesome poerations such as covering covering, as easy as rolling off a log error, the damage equipment of causing.Simultaneously, because device housings is capped thing and blocks, influenced equipment appearance.
For being used and operate television set, microcomputer, various demonstrations, monitor etc. bring convenience, and minimizing dust etc. propose this invention of housing of TV set of band shielding curtain to the pollution and the infringement of kinescope screen.
It is as described below to implement this invention:
Shielding curtain can be on tv shell laterally (vertically), or vertical (up and down) layout, this shielding curtain can be divided into horizontal left and right directions switch according to layout.Two kinds on vertical above-below direction switch.
2. shielding curtain and tv shell structure: on the engine housing that (should leave the gap more than three millimeters) before kinescope screen, two gathering sills for shielding curtains guiding usefulness are arranged, these two gathering sills can hold two limits of shielding curtain fabric width respectively.Be furnished with two backguys (or drawstring) in gathering sill, backguy is hidden in the gathering sill, from not seeing backguy in appearance.Backguy one end draws to lead to hold with shielding curtain and links, and the other end is fixed on the spool.The shielding curtain stiff end is fixed on the curtain rolling shaft, and curtain rolling shaft is contained in the roller shutter box.
The switch of shielding curtain is achieved in that when cutting out shielding curtain, and the backguy axle is rotated, the backguy axle in rotation process with the backguy rolling on the backguy axle, shielding curtain is pulled out in roller shutter box by backguy, shielding curtain blocks before kinescope screen, shielding curtain is closed.When opening shielding curtain, curtain rolling shaft is rotated, curtain rolling shaft involves in shielding curtain in the roller shutter box in rotation process, and shielding curtain draws leads end backguy is pulled out from spool, and kinescope screen is exposed, and shielding curtain is opened.
3. the making of shielding curtain: shielding curtain can be the flexible metal curtain, also can fabric, making such as leather.
4. the switch form of shielding curtain: shielding curtain can be realized two kinds of automatic switch and hand switches.
(1), when implementing automatic switch, be power source with the dc micro-motor.When miniature cocurrent electromotor is unidirectional, can adorn commutator, with the motion that realizes opening and close both direction.Also can adopt the reversible dc micro-motor.The shielding curtain motor switch can be installed on the casing.
(2), when implementing hand switch, available hand directly draws the pass shielding curtain, also manual knob switch can be installed.For making shielding curtain be easy to switch, also Spring balanced device etc. can be installed on the shielding curtain spool.
(3), the switch shielding curtain also can adopt the mode of flexible helical feed, or mesh the curtain hole with gear tooth and realize.Also shielding curtain can be hidden in the casing interlayer in addition, when closing shielding curtain, shielding curtain be pulled out from interlayer.When opening shielding curtain, again it is sent back in the casing interlayer.
For making shielding curtain when closing, the heavy curtain good looking appearance should be decorated with decorative pattern on heavy curtain, pattern and picture etc., so that the tv shell of band shielding curtain, outward appearance is graceful more.
Along with updating of this electronic device of picture tube, and the flat board of kinescope screen, the appearance of corner and large-screen is blocked picture tube with shielding curtain, can prevent from that the unexpected explosion of picture tube from causing to hurt sb.'s feelings.
In sum, the housing of TV set of this band shielding curtain can be extensively as microcomputer, television set, and core shells such as all kinds of demonstrations, monitor are a kind of desirable novel casings.
Claims (4)
1, the housing of TV set of band shielding curtain, by shielding curtain, two gathering sills, article two, backguy or drawstring, spool or take-up spool, shielding curtain axle, miniature cocurrent electromotor, manual roller shutter knob, roller shutter box, shielding curtain automatic switches etc. have been formed engine housing, the invention is characterized in two gathering sills of device on engine housing, can hold the fabric width two ends of shielding curtain respectively, when shielding curtain was closed, kinescope screen crested curtain blocked, after shielding curtain was opened, kinescope screen was exposed.
2,, it is characterized in that shielding curtain can realize automatically and manual two kinds of on-off modes that two gathering sills can be hidden in gathering sill with shielding curtain fabric width two ends by the housing of TV set of the described band shielding curtain of claim 1.
