Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-7 is please referred to, embodiment according to the present invention provides a kind of for protecting computer display information safety
Peep-preventing device, including lower case 1 and upper housing 2, lower case 1 are symmetrically disposed on the two sides of the bottom of upper housing 2.
Card slot 3, first sliding groove 4 and second sliding slot 5 are disposed on 1 opposite side of lower case, card slot 3 and computer are aobvious
The frame of display screen matches, and the bottom end of card slot 3 is hatch frame, and the lower inside of first sliding groove 4 and second sliding slot 5 is symmetrically set
It is equipped with restriction protrusion 6, the first pull rod 7 and the second pull rod 8, position at the both ends of the first pull rod 7 are provided between symmetrical lower case 1
Inside corresponding first sliding groove 4, it is located inside second sliding slot 5 at the both ends of the second pull rod 8.
Upper housing 2 is cavity structure, and the inside upper part of upper housing 2, which is symmetrically arranged with first, puts film frame 9 and second and put film frame
10, first, which puts film frame 9 and second, puts and is provided with strainer 11 at the both ends of film frame 10, the middle inside setting of upper housing 2
There are two groups of adjustment roll shafts 12, the both ends for adjusting roll shaft 12 are rotatablely connected with the inner wall of upper housing 2, the lower inside of upper housing 2
It is provided with retaining mechanism 13 and single-chip microcontroller 14.
Wherein, strainer 11 includes that (brand: outstanding person contains motor, operating voltage 3V, using DC voltage, diameter to motor
6mm, peak torque 77g/cm), motor puts film frame 9 and second with first respectively and puts the transmission connection of film frame 10, passes through the drive of motor
Power while being put film frame 9 and second first and being put so that first puts film frame 9 and second and put film frame 10 using winding state is kept
After film expansion on film frame 10, also film can be made to keep certain tension, so that film is more smooth.
Wherein, the input terminal of retaining mechanism 13 is connect with 14 output end of single-chip microcontroller, the input terminal of single-chip microcontroller 14 be embedded at
The output end of the fingerprint recognition panel 15 on 2 top of upper housing connects, and identifies fingerprint by fingerprint recognition panel 15, could solve unlocking
Tight mechanism 13, realizes that the special messenger of display is dedicated.
Wherein, retaining mechanism 13 includes electromagnet 16, electromagnet 16 and the permanent magnet 17 for being set to 13 middle part of retaining mechanism
Matching, be set to first put film frame 9 and second put on film frame 10 film both pass through retaining mechanism 13 and with corresponding first pull rod 7
It is fixedly connected with the second pull rod 8, permanent magnet 17 is located in the groove 18 in the retaining mechanism 13 between two films, in electromagnet 16
When disconnecting power supply, attraction of the electromagnet 16 by permanent magnet 17, since electromagnet 16 is fixed, permanent magnet 17 is along recessed
Slot 18 realizes locking to sliding at electromagnet 16, and when electromagnet 16 is powered, the magnetic force that electromagnet generates repels each other with permanent magnet 17,
Therefore permanent magnet 17 is moved along groove 18 to the direction far from electromagnet 16, realizes unlock, while to avoid damage light polarizing film,
The also settable protective pad between electromagnet 16 and permanent magnet 17, protect light polarizing film when electromagnet 16 and permanent magnet 17 clamp not
It is impaired.
Wherein, the first pull rod 7 is provided with the first plectrum 19 far from the side of the second pull rod 8, and the first pull rod 7 is located at second and draws
20 top surface of the second plectrum on bar 8 can be such that the first pull rod 7 realizes during drop-down with the second pull rod 8 and link, while
It can be convenient for the free switching between peep-proof and non-peep-proof.
Wherein, the inside top of first sliding groove 4 and second sliding slot 5 is embedded with touch-switch 21 (switch height is
3.5mm, operation force range: 70-300gf), touch-switch 21 is matched with corresponding first pull rod 7 far from the second pull rod 8, when making
When being left with personnel are of short duration and wound light polarizing film and peep-proof film, arrives and correspond to the first pull rod 7 and the winding of the second pull rod 8
Sliding slot top when can touch touch-switch 21,21 feedback signal of touch-switch disconnects electromagnetism to single-chip microcontroller 14, single-chip microcontroller 14
After the power-on circuit of iron 16, so that retaining mechanism 13 is locked again.
Working principle: in use, first removing the light polarizing film on the liquid crystal display panel of dedicated display screen, first puts 9 He of film frame
Second, which puts on film frame 10 volume respectively, peep-proof film and light polarizing film, and computer appointees must be referred to by fingerprint recognition panel 15
Line identification, fingerprint correctly connect the power-on circuit of electromagnet 16 in retaining mechanism 13 by single-chip microcontroller 14 afterwards, and electromagnet 16 is powered
After generate magnetic field, the magnetic field generate magnetic force and permanent magnet 17 act on, thus by permanent magnet 17 be pushed into groove 18 inside so that
Electromagnet 16 is separated with permanent magnet 17, no longer clamping light polarizing film (display interior has two layers of light polarizing film, and one layer is leaned on close to sources, one
Layer is located on the liquid crystal display panel of display screen, only removes the light polarizing film on liquid crystal display panel, if not placing one layer of polarisation outside
Blank pictures are shown in film, display screen, and original picture could be shown by only again covering light polarizing film, not so operator from
Oneself also can't see), first pull rod 7 can be pulled downward on along first sliding groove 4 by pulling the first plectrum 19 at this time, until first draws
Bar 7 is limited the limit of protrusion 6, since the second plectrum 20 being located on the second pull rod 8 is located at the bottom surface of the first pull rod 7, so that the
Two plectrums 20 and the second pull rod 8 are moved down likewise as the first synchronizing for pull rod 7, and make the second pull rod 8 by corresponding second
Restriction protrusion 6 in sliding slot 5 limits, and is now placed in first and puts the peep-proof film on film frame 9 and put positioned at second inclined on film frame 10
Light film is covered on display screen front, and is tensioned by the strainer 11 inside upper housing 2, schemes after light polarizing film covering display screen
As text can be shown, peep-proof film can by viewing angle control in 60 °, when user of service need it is of short duration leave equipment, at this time will
First pull rod 7 and the second pull rod 8 release corresponding restriction protrusion 6, under the drive of strainer 11 first put it is anti-on film frame 9
It peeps film and puts film frame 10 positioned at second and rotate, the first pull rod 7 and the second pull rod 8 rise therewith along corresponding sliding slot until upper housing
2 bottom, after the first pull rod 7 and the second pull rod 8 reset completely, single-chip microcontroller 14 disconnects the power-on circuit of electromagnet 16, at this time
Electromagnet 16 and permanent magnet 17 are attracting, again clamp light polarizing film, so that light polarizing film can not pass through the pulling of the first pull rod 7
And move, after the covering for not having light polarizing film on display screen, it is shown as white.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
