Abstract
The utility model relates to a frame for a book monitoring instrument, which belongs to a sensing device and comprises a frame (1), a monitoring wire (2) and a monitoring wire (3). The utility model is characterized in that the monitoring wire (2) is fixedly connected with E, F, A, B, P, C and D in the frame (1), and the monitoring wire (3) is fixedly connected with E, W, O, P, C and D in the frame (1). The utility model has the advantages of simple structure and sensitive and accurate monitoring, can effectively eliminate a blind zone and prevents books from being lost.
Description
The utility model relates to a kind of framework of books monitor, relates to a kind of stolen framework that is used with monitoring instrument of books that is used to prevent specifically, belongs to sensing equipment.
At present, development along with society, the library has carried out the management of opening access, thereby, the stolen phenomenon of books is more serious, in order to prevent that books are stolen, a kind of books monitor has appearred in the society, preventing to lose book, yet existing books monitor is because the framed structure that itself and monitoring instrument are used is unreasonable, so caused the monitoring effect of books monitors undesirable, incorrect, its main cause is that the layout of detection lead in the framework is unreasonable, when the book that has magnetic stripe passes through the framework of existing books monitor, when the magnetic field that magnetic stripe produces is parallel with the detection lead in the framework, detector is reaction not, that is to say that detector exists the deficiency of " blind area ", so the layout of the detection lead in the existing books monitor framework awaits improving.
The purpose of this utility model is to design a kind of framework that has the books monitor of two cover monitoring leads, to overcome the deficiency that existing monitor exists " blind area ".
The purpose of this utility model is to realize like this, it mainly is made up of framework (1), monitoring lead (2) and (3) three parts of monitoring lead, it is characterized in that: monitor lead (2) along E, F, A, B, P, C, affixed being equipped with of D in the framework (1), and also monitor lead (3) in the framework (1) along E, W, O, P, affixed being equipped with of C, D.
Its feature also is: the frame that described framework (1) is made up of AG straight-bar and ABCD knee and GD straight-bar is connected with FK, OP, four braces of WC, FE in the frame.
The utility model compared with prior art, it is simple in structure, sensitive monitoring is accurate, can effectively get rid of " blind area ", prevents losing of books.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is the utility model one-piece construction synoptic diagram.
Wherein: 1, framework, 2, the monitoring lead, 3, the monitoring lead.
Referring to accompanying drawing: it mainly is made up of the utility model embodiment the two cover monitoring leads that are provided with in two frameworks and the framework, two frameworks have been formed a passage, described framework 1 is by the affixed frame that becomes of AG straight-bar and ABCD knee and GD straight-bar, is connected with FK, OP in the frame, four braces of WC, FE are formed framework.Along E, F, A, B, P, C, the affixed monitoring lead 2 that is equipped with of D, also another set of monitoring lead 3 is installed in the framework 1 in the framework 1 along E, W, O, P, C, D are affixed.When the book that has magnetic stripe passes through passage, with regard to the magnetic field and the whole parallel problems of the detection lead in the framework of having avoided magnetic stripe to produce, that is to say when the book that has magnetic stripe passes through passage, the magnetic field that magnetic stripe produces can be not parallel with the interior any detection lead of framework, and the magnetic line of force will be cut by lead, makes lead produce induction current, detector just responds, and report to the police, that is to say that there be not " blind area " in detector, can effectively prevent losing of books.
Claims (2)
1, a kind of framework of books monitor, it mainly is made up of framework (1), monitoring lead (2) and (3) three parts of monitoring lead, it is characterized in that: monitor lead (2) along E, F, A, B, P, C, affixed being equipped with of D in the framework (1), and also monitor lead (3) in the framework (1) along E, W, O, P, affixed being equipped with of C, D.
2, the framework of books monitor according to claim 1, its feature also is: the frame that described framework (1) is made up of AG straight-bar and ABCD knee and GD straight-bar is connected with FK, OP, four braces of WC, FE in the frame.
