Description

A module is pressed to locking formula for push type intelligence seal

Technical Field

The invention relates to a seal, in particular to a locking type pressing module for a pressing type intelligent seal.

Background

The existing seal, especially the official seal, is the necessary office equipment that the unit or the legal person approve or prove the corresponding document validity, and the seal stamped on the document expresses the validity and authenticity of the document. Once the seal is lost, the seal is maliciously utilized by illegal personnel, and the serious consequence of directly or indirectly damaging the benefits of related personnel and institutions is caused, so that special personnel in a company generally manage the seal and are responsible for the use, preservation and maintenance of the seal. However, there are some special cases objectively, for example, some enterprises and public institutions borrow official seals, and seal managers cannot seal the seals at a predetermined place with seal persons; for example, the seal manager is on business, has a leave, and needs to use the seal, and the situation causes that the seal manager cannot ensure that the seal is used or has malicious use after being taken away, so that the intelligent seal appears on the market.

The traditional intelligent seal is usually driven by an electromagnet, when the traditional intelligent seal is electrified, the electromagnet drives the seal to be pressed downwards so as to realize sealing, and after the electromagnet is powered off, the seal is reset and moves upwards; however, the stamp driven by the electromagnet can generate instant acceleration and large acceleration at the moment of electrification, so that instant impact is formed, the stamp moves downwards at a high speed and collides with paper, and when the force for pressing the stamp is insufficient, the impact force easily causes slight deviation of the stamp impact, so that stamping deviation and double images are caused, and the stamping quality is influenced; the generated impact force influences the use hand feeling and the comfort; meanwhile, the seal is poor in safety, is easily influenced by an external magnetic field and poor in anti-interference capability, the internal electromagnet can be triggered to seal under the influence of strong magnetism, the overall safety is not ideal, and the seal is easily stolen illegally; and traditional intelligent seal can't change the seal, because intelligent seal price is higher, when the company renames, need to change a new intelligent seal, has increased company's cost.
