Single-driving dual-fixing seal support with anti-magnetism anti-theft function

Abstract

The invention provides a single-driving dual-fixing seal support with an anti-magnetism anti-theft function. The single-driving dual-fixing seal support comprises a shell, a dual-output driving deviceand a seal locking mechanism. The dual-output driving device is horizontally arranged in a mounting cavity, and an output shaft of the dual-output driving device is rigidly connected with a pin shaftsliding in a pin hole and can push the pin shaft to stretch and contract axially. The seal locking mechanism comprises a transmission assembly and a locking bolt, wherein the transmission assembly isconnected with the pin shaft and capable of converting linear motion of the pin shaft into circular motion, and the locking bolt is arranged at the output end of the transmission assembly and coaxialwith a locking screw hole. The head portion of the locking bolt is connected to the interior of the locking hole in a threaded mode. The single-driving dual-fixing seal support with the anti-magnetism anti-theft function is compact in structure, convenient to assemble, and good in locking effect and anti-theft and anti-disassembly effects. The dual-locking function of the seal support and a sealbody is realized through a single-driving device. The production cost and the overall volume are reduced, and the production cost is low.

Description

technical field [0001] The invention relates to a seal, in particular to a single-drive double-fixed stamp support with anti-magnetic and anti-theft functions. Background technique [0002] Existing seals, especially official seals, are necessary office equipment for units or legal persons to recognize or prove the validity of corresponding documents, and the seal on a document indicates the validity and authenticity of the document. Once the seal is lost and used maliciously by criminals, it will directly or indirectly cause serious consequences that damage the interests of relevant personnel and institutions. Therefore, there are usually special personnel in the company to manage the seal and be responsible for the use, preservation and maintenance of the seal. However, there are still some special circumstances objectively. For example, the official seals of some enterprises and institutions will be borrowed, and it is impossible for the seal management personnel to follo...

Problems solved by technology

However, there are still some special circumstances objectively. For example, the official seals of some enterprises and institutions will be borrowed, and it is impossible for the seal management personnel to follow the seal user to the predetermined place to stamp the seal; This kind of situation makes the seal management personnel unable to ensure that the seal will be used seriously or maliciously used, so there are smart seals on the market.

[0003] Traditional smart seals are identified by passwords or fingerprints, and are activated and stamped after identity authorization; in order to improve the security of smart seals, and at the same time facilitate the replacement of different seals to reduce the cost of use, a sliding Seat, which is used to install the stamp body, and is used to connect with the drive mechanism in the casing. There is a locking device between the stamp body and the stamp bracket, which is used to fix the stamp body on the stamp bracket. Usually, the locking device is composed of The push-pull electromagnet realizes locking or loosening to facilitate the replacement of different stamps. At the same time, the driving mechanism used to drive the bracket to move to achieve stamping is also a push-pull electromagnet. When external strong magnetism or Tesla coil interference is used , there is a certain probability that the electromagnet will act. When the push-pull electromagnet as the driving device acts, the stamping action will be realized. Mandatory stamping can be achieved when stealing, which has great potential safety hazards
