[0002] At present, in the work of administrative organs, enterprises and institutions, banks, postal services, social organizations, etc. using various seals such as administrative official seals, financial official seals, contract seals, invoice seals, and steel seals, a flat seal is generally used. Seal, this kind of seal is easy to counterfeit, the number of times of use is not limited, it does not have anti-theft function, and the security is low, resulting in cases of fake seals and stamped seals, which will cause immeasurable consequences to the units, individuals and related units and individuals who use the seals

Embodiment Construction
[0028] refer to figure 1 , a kind of counting type electromagnetic seal that the present invention proposes, comprises: seal body 1, connecting head 2, expansion screw 3, outer cylinder body 4, sheath shell 5, cover plate 6, inner sleeve head 7, isolation plate 8 and control module.
[0029] The isolation plate 8 is installed inside the outer cylinder 4 perpendicular to the central axis of the outer cylinder 4, and divides the inside of the outer cylinder 4 into a first chamber 4-1 and a second chamber 4-2. A cover plate 6 is mounted on the outer cylinder 4 for sealing the second chamber 4-2. The inner sleeve 7 is slidably installed in the first chamber 4-1 and is connected to the isolation plate 8 by a spring 9. The extension direction of the spring 9 is parallel to the direction of the central axis of the outer cylinder 4, so that the inner sleeve 7 is pulled in the second chamber by the spring 9. 4-2 Slide along the axis direction of the outer cylinder 4.

The invention provides a counting type electromagnetic stamp. The counting type electromagnetic stamp comprises a stamp body, a connector, an expansion screw, an outer barrel, a protection sleeve shell, a cover plate, an inner sleeve head, a separation plate and a control module. According to the counting type electromagnetic stamp, relative motion of the inner sleeve head and the outer barrel iscontrolled through a spring and electromagnets. According to magnetic field force, the working voltage strength of the electromagnets is controlled, and magnets can be controlled to drive the fine turning distance of the inner sleeve head relative to the outer barrel. Thus, the stamp body is mounted on the inner sleeve body through the connector, the fine turning distance, driven by the magnets, of the inner sleeve relative to the outer barrel is equal to the fine turning distance, driven by the magnets, of the stamp body relative to the outer barrel.
Description
technical field [0001] The invention relates to the technical field of stamps, in particular to a counting electromagnetic stamp. Background technique [0002] At present, in the work of administrative organs, enterprises and institutions, banks, postal services, social organizations, etc. using various seals such as administrative official seals, financial official seals, contract seals, invoice seals, and steel seals, a flat seal is generally used. Seal, this kind of seal is easy to counterfeit, the number of times of use is not limited, does not have anti-theft function, and has low security, resulting in cases of fake seals and stamped seals, causing immeasurable consequences to units, individuals and related units and individuals who use seals. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a counting electromagnetic stamp. [0004] A counting electromagnetic stamp proposed by t...
