Card library structure capable of stably rotating and fixing

Abstract

The invention relates to a card library structure capable of stably rotating and fixing. The card library structure comprises a card library body which is of a hollow cylindrical barrel shape, whereintwo round end parts of the card library body are independently provided with a card library driven gear, and a plurality of troughs are evenly arranged on the circumferential surface of the card library body between two card library driven gears; each card library driven gear is independently meshed with a power gear, and two power gears are connected through a power gear shaft; and the hollow internal surface of the card library body is evenly provided with three bearing supporting shafts, one side of the card library body is also provided with a driving motor, and the driving motor is fixedly connected with the power gear. The card library structure has the advantages of simple integral structure, small volume, flexibility in installation, stability in fixing and rotation and small possibility of loosening, and the use efficiency of the card library can be improved.

Description

technical field [0001] The present invention relates to the technical field of card management, and more specifically, the present invention relates to a rotating and fixed stable card library structure. Background technique [0002] After the certificates are produced, people usually need to go to the business window of the certificate office to collect them manually. Not only do they need to wait in line, but the collection time is limited to the office hours of the certificate office. Moreover, when the certificate is obtained, the certificate is manually registered and issued, and the certificate office needs to invest a lot of human resources for this, and the efficiency is low. [0003] With the development of society and technology, various documents such as ID cards, passports, residence permits, etc. are all in the form of cards, bank cards and social security cards are also in the form of cards. Such cards are usually stored in the card issuing equipment before the...
