Problems solved by technology
[0003] 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.
[0004] Traditional smart seals cannot lock and fix the cover, and there are certain safety hazards. For example, the paper is forcibly stuffed into the lower open end and contacted with the bottom surface of the seal body to seal; low coefficient

The invention provides a stamp linkage double lock mechanism, which includes a housing, a cover, a block, a bayonet and a linkage mechanism; a second cavity in the side wall of the housing, and an annular slot is formed through the bottom of the second cavity; The upper end of the cover is provided with an annular protrusion, and the side wall of the annular protrusion is provided with a first clamping part; the clamping block is rotatably installed in the second cavity, and the head of the clamping block is provided with a second clamping part; the bayonet pin It is horizontally fitted in the second cavity, and the head of the bayonet can move into the first cavity and form a limit part for limiting the downward movement of the stamp body; the linkage mechanism is installed in the second cavity to push the The locking block rotates to realize the clutch between the arc-shaped protrusion and the arc-shaped groove, and pushes the bayonet pin to slide left and right; the seal linkage double-lock mechanism of the present invention has a compact structure, convenient assembly, reliable and safe operation The coefficient is high.
Description
Technical field [0001] The present invention relates to a seal, and more particularly to a seal linkage double lock mechanism. Background technique [0002] The existing seal, especially the official seal, is the necessary office equipment for the unit or legal person acknowledged or proves the effectiveness of the corresponding document, indicating the validity and authenticity of the document. Once the seal is lost, the serious consequences of malicious use, direct or indirectly cause damage to relevant personnel and institutional benefits, and therefore, there is usually the company has a special personnel management seal, which is responsible for the use, preservation and maintenance of the seal. [0003] However, there are some special situations in objective, such as some enterprises and institutions of enterprises, the seal management personnel cannot follow the seal of the book, and, for example, the seal management staff, there is something to leave, but also need Use th...
