Description
Technical field
The invention belongs to watching shield cover field, is to be related to a kind of visual angle and position for Anti-spying hood of cipher keyboard specifically
Joint debugging mechanism, belong to protecting information safety equipment technical field.
Background technology
Nowadays bank counter, ATM, the super cashier of business, POS etc. application non-cash transaction occasion, it is necessary to
People are manually entered password authentification by code keypad and could complete to merchandise, and these non-cash transaction modes are lived to people and work
While offering convenience, hidden danger also has been buried to people's property safety, then can be big once trading password is stolen by lawless people
The risk of big increase property loss, therefore, people should block as far as possible when inputting password, avoid revealing transaction because being peeped
Password.
Therefore, setting up the watching shield cover for having fixed form on code keypad, people are provided with grid, bar shaped by watching shield cover
The button on watch window identifying cipher keyboard that the array distributions such as hole are formed, the visible angle of this watch window is to set in advance
It can not be changed after putting and installing, however, people's height build is not quite similar, the visible angle set in advance is not applied for
Owner, people only coordinate the visible angle set in advance by adjusting itself limbs, can just see code keypad, this
Although anti-peeping cover with certain peep-proof effect, its applicability deficiency, the comfort of people and convenience deficiency,
A kind of watching shield cover of the code keypad of fixed form as disclosed in Chinese patent 201610651360.7；Also there is Chinese patent
201520623770.1 disclose a kind of autonomous device cipher peeping-proof cover, by provided with multiple both ends respectively with side plate be hinged
Blade forms the adjustable watch window of visible angle, still, the watch window of this venetian blind type, on the one hand, due to each leaf
Piece is respectively articulated with, and it adjusts the flexibility deficiency of process, and on the other hand, the field range after adjustment can adjust with blade angle
And change, it may appear that it cannot be seen that the situation of code keypad overall picture is obtained, and also the adjustable extent at visual angle is also limited, it is clear that and it is this
Watching shield cover equally exists applicability, comfort and convenience deficiency problem.
Therefore, a kind of visible angle adjusting range of this area serious hope exploitation is big, visually affords a wide field of vision, flexible adjustment, peep-proof
Effect is good, using comfortable Anti-spying hood of cipher keyboard, with meet people for Anti-spying hood of cipher keyboard applicability it is wide, have and make
With comfortableness and the demand of convenience, but the report of so far there are no correlation technique or product.
The content of the invention
In view of the above-mentioned problems existing in the prior art and demand, prevent it is an object of the invention to provide one kind for code keypad
Visual angle and the position joint debugging mechanism of cover are peeped, the synchronous adjustment of visual angle and position can be achieved so that the sight of operator all the time can
Project on keyboard；It is simple in construction, and effect is got twice the result with half the effort.Use the visible angle of the Anti-spying hood of cipher keyboard of the joint debugging mechanism
Adjusting range is big, visually afford a wide field of vision, flexible adjustment, peep-proof effect, using comfortable, meet people for code keypad peep-proof
Cover applicability is wide, has comfort and the demand of convenience.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of visual angle and position joint debugging mechanism for Anti-spying hood of cipher keyboard, including the left branch located at code keypad both sides
Support side plate and right support side plate and the sight guide plate being arranged above code keypad, it is characterised in that：The sight is oriented to
Plate both sides with the left support side plate and the right support side plate slidable connection, are divided in the both sides of the sight guide plate respectively
Not She You two cylindrical sliders being spaced apart, the left support side plate and the right support side plate top are respectively equipped with two
The pilot hole being adapted with the cylindrical slider.
A kind of embodiment, the pilot hole are arcuate guide hole or linear pilot hole.
A kind of embodiment, the sight guide plate are provided with several thin-walled fence structures for being vertically directed through hole.
Further embodiment, the vertical through hole are set for array distribution.
Further embodiment, it is described to be vertically directed through hole to be cross-linked to form just by horizontal riser and longitudinal riser
Square or rectangular through-hole.
Further embodiment, the peep-proof film of one layer of only vertical one-way viewable is also covered with the sight guide plate bottom.
A kind of embodiment, the left support side plate and the right support side plate are in the L-type structure of specular.
Preferably, front side baffle plate is additionally provided with front side of the code keypad, to prevent because straight on front side of code keypad
Connect exposure or mirror-reflection and cause the leakage of Password Input information.
As further preferred scheme, the left support side plate, the right support side plate, the front side baffle plate with it is described
Light-operated inductive lighting lamp is additionally provided with the cavity that sight guide plate is formed.
