Embodiment 1

[0039] Such as Figure 1-Figure 5 As shown, the system for preventing books from being stolen in the present invention includes a book anti-theft instrument body, the anti-theft instrument body includes a support frame 1 and a controller, and a prompt assembly is arranged on the top surface of the support frame 1, and the prompt assembly includes Moving plate 2, electromagnet 3 and torsion spring 4, one end of the moving plate 2 is hinged to one end of the top surface of the support frame 1, and an iron bar 5 is arranged at the other end of the moving plate 2, and the electromagnet 3 is arranged on the support The other end of the top surface of the frame 1, the axis of the torsion spring 4 is parallel to the axis of the hinge, and the torsion spring 4 is located on the side of the hinge axis close to the electromagnet 3, and the torsion arms of the torsion spring 4 are respectively connected to the moving plate 2 and the support The top surface of the frame 1 is in contact, a...

Embodiment 2

[0043] The present invention is based on embodiment 1, and the present invention is further described.

[0044] Such as Figure 1-Figure 5 As shown, the system for preventing books from being stolen in the present invention is provided with a support block 6 between the electromagnet 3 and the top surface of the support frame 1, and a locking slot is provided on the support block 6, and the electromagnet 3 is located at the bottom of the locking slot, rotating the moving plate 2 around the hinge axis can make the iron bar 5 be located in the locking slot and be attracted by the electromagnet 3.

[0045] The cross-section of the support block 6 is semicircular, and the cross-section of the locking groove is consistent with the size of the cross-section of the support block 6 .

[0046] Both the iron bar 5 and the locking groove are arranged in a semicircle, which is beneficial to increase the adsorption surface of the electromagnet 3 in a limited space and improve the stability ...

Embodiment 3

[0048] The present invention is based on embodiment 1, and the present invention is further described.

[0049] Such as Figure 1-Figure 5 As shown, the system for preventing books from being stolen in the present invention is provided with a gear assembly on the top surface of the support frame 1 on the side where the hinge axis is away from the electromagnet 3, and the gear assembly includes a gear block 7 connected in sequence , a spring 8 and a moving rod 9, one end of the stop block 7 is connected to the top surface of the support frame 1, and an installation groove 10 is provided on the side wall of the stop block 7 close to the moving plate 2 and away from the support frame 1, The spring 8 is located in the installation groove 10, and one end of the spring 8 is connected with the groove bottom of the installation groove 10, and the other end of the spring 8 is connected with the side wall of the moving rod 9, and the axis of the moving rod 9 is parallel to the hinge axi...

Abstract

The present invention discloses a system of preventing books from being stolen. The system comprises a book anti-theft instrument body, and the book anti-theft instrument body comprises a supporting rack and a controller. A prompting assembly is arranged on the top surface of the supporting rack and comprises a movable plate, an electromagnet and torsional springs, one end of the movable plate is in hinge joint with the supporting rack, and the other end is equipped with a bar iron. The electromagnet is arranged on the top surface of the supporting rack, the bar iron is attracted by the electromagnet, and the tail ends of the torsion arms of the torsional springs get close to each other. The electromagnet is connected with a controller, when the electromagnet is in power off, the torsional springs recover to the original states, and one end of the movable plate far away from a hinging axis is far away from the supporting rack. When the book anti-theft instrument body detects that a person takes out a book that is not borrowed normally out of a reading room, the electromagnet is in power off, the movable plate losing the attraction of the electromagnet rotates under the action of the torsional springs, after seeing that the movable plate on the supporting rack starts, the administrative staff can accurately and quickly determine the person with the book that is not borrowed normally at a specific exit.

Description

technical field [0001] The invention relates to an anti-theft device, in particular to a system for preventing books from being stolen. Background technique [0002] Book anti-theft equipment can effectively prevent loss of books, facilitate and simplify management, help improve work efficiency, and help create a good office and reading environment. With the continuous development of science and technology, library open-shelf management reflects the great progress of the library in adapting to the development of the times in terms of facilitating readers' free choice, improving book reading utilization, and improving library work efficiency. The disadvantages of open-shelf service-losing books and tearing pages are also prominent problems in management work. How to fully consider the characteristics of the open-shelf service in the layout of the library, give full play to its advantages, and take various auxiliary measures to reduce the inconvenience caused by the open-shel...
