Locking type pressing module for pressing type intelligent seal

Abstract

The invention provides a locking type pressing module for a pressing type intelligent seal. The locking type pressing module comprises an outer support, an inner support and a driving device, a first mounting cavity with the upper end and the lower end opened is formed in the outer support, auxiliary bolts and strip-shaped guide grooves are evenly distributed on the side wall of the first mounting cavity in the circumferential direction, the auxiliary bolts are elastic, the heads of the auxiliary bolts can extend into the first mounting cavity, and the length directions of the strip-shaped guide grooves are parallel to the axis of the first mounting cavity; the inner support is vertically matched in the first mounting cavity in a sliding mode, the seal is arranged at the bottom of the inner support, a first pin hole and a main pin are arranged on the inner support, and a first elastic component is arranged in the outer support; and the driving device can push the auxiliary bolts and the main pin to slide. The locking type pressing module for the pressing type intelligent seal is compact in structure, convenient and labor-saving to operate, stable in driving, good in reliability, high in safety, good in anti-interference effect and high in safety, the seal can be rapidly detached and replaced, the seal can be rapidly replaced according to needs, and the cost is reduced.

Description

technical field [0001] The invention relates to a stamp, in particular to a locking pressing module for a pressing smart stamp. 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 stamped 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 follow the seal user to the p...

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 stamps are usually driven by an electromagnet. When energized, the electromagnet drives the stamp down to achieve stamping. After the electromagnet is powered off, the stamp resets and moves up; but the stamp driven by the electromagnet, at the moment of power on, It will produce instantaneous acceleration, and the acceleration is large, so an instantaneous impact is formed. The stamp moves down at a high speed and collides with the paper. The impact will affect the quality of stamping; the resulting impact will affect the feel and comfort of use; at the same time, the seal is not safe, easily affected by external magnetic fields, and has poor anti-interference ability. The internal electromagnet can be triggered by strong magnetism, and the overall security is not good. Ideal, easy to be illegally embezzled; and the traditional smart seal cannot replace the seal. Due to the high price of the smart seal, when the company changes its name, it needs to be replaced with a new smart seal, which increases the cost of the company
