the base is fixed on the cassette seat;
the eccentric column is arranged on the inner side of the base and matched with the eccentric guide groove;
the reciprocating spring is arranged on the outer side of the base and is connected with the eccentric column.
The working process is as follows: when the data card is pressed to enter the cassette seat along the concave-convex fit between the cassette seats without errors, the eccentric column in the eccentric reciprocating mechanism displaces along the eccentric guide groove at the end position of the data card until the data card keeps balanced and locked under the action of the eccentric reciprocating mechanism and the pressure spring, and the data card realizes pressing self-locking at the moment.
When the data card is pressed again, the eccentric column recovers an unstressed state under the action of the reciprocating spring, the eccentric reciprocating mechanism is not stressed any more in the process, the data card is only pushed by the pushing force of the action of the pressure spring, and the data card slides out along the concave-convex matching of the data card and the card box seat, so that the self-discharging pressing is realized.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, which refer to fig. 1 to 4.
The invention relates to a pressing self-locking self-unloading structure of a data card, which mainly comprises a data card 1, an eccentric guide groove 2, an eccentric reciprocating mechanism 3, a card box seat 4 and a pressure spring 5, wherein the eccentric reciprocating mechanism 3 comprises a base 301, a reciprocating spring 302 and an eccentric column 303.
The working state of the data card 1 is matched with a connector corresponding to the card box seat 4, when the data card 1 needs to be matched with the connector in the card box seat 4, the data card 1 is pressed to enter the card box seat 4 along the concave-convex matching between the card box seat 4 without errors, the eccentric column 303 in the eccentric reciprocating mechanism 3 displaces along the eccentric guide groove 2 at the end position of the data card 1 until the data card 1 keeps balanced and locked under the action of the eccentric reciprocating mechanism 3 and the pressure spring 5, and at the moment, the data card 1 realizes the pressing self-locking.
When the data card 1 needs to be separated from the butting connector in the card box seat 4, and the data card 1 is pressed again, the eccentric column 303 is restored to an unstressed state under the action of the reciprocating spring 302, the eccentric reciprocating mechanism 3 is not stressed any more in the process, the data card 1 only has the thrust force of the action of the pressure spring 5, and the data card 1 slides out along the concave-convex matching of the data card 1 and the card box seat 4, so that the self-unloading function is realized.
The eccentric reciprocating mechanism 3 is fixed on the cassette seat 4, and the eccentric column 303 only reciprocates in the vertical direction under the limit of the reciprocating spring 302 (as shown in fig. 3). The eccentric guide slot 2 is designed with a unique track, and the track is matched with the eccentric column 303, when the data card 1 is pressed into the cassette seat 4, the eccentric column 303 will move along the lower edge of the eccentric guide slot 2, from the position a to the position f in fig. 4, the position a eccentric column 303 is not subjected to external force, and the rest positions of the eccentric column 303 will generate mutual acting force with the eccentric guide slot 2. At this time, the eccentric column 303 deviates from the original position a, the acting force generated by the eccentric guide slot 2 on the data card 1 and the eccentric column 303 at the position f is balanced with the acting force of the compression spring 5 on the card box seat 4, the data card 1 is fixed, and the data card 1 is self-locked (see fig. 4).
When the data card 1 is pressed again, the eccentric column 303 will move along the upper edge of the eccentric guide groove 2, from the position f to the position a in fig. 4, the position a of the eccentric column 303 is free from the external force, and the rest positions of the eccentric column 303 will generate the mutual acting force with the eccentric guide groove 2. At this time, the eccentric column 303 is automatically forced to return to the original position a through the position g, the eccentric guide groove 2 on the data card 1 and the eccentric column 303 reach a new balance at the position h (because h, i and a are at the same position), and at this time, the data card 1 is only under the action of the compression spring 5, and the data card 1 is self-unloaded (see fig. 4).
The invention describes the pressing self-locking and self-discharging process of the data card, the key structural design and the like in detail on the basis of introducing a pressing self-locking self-discharging structure of the data card. The data card 1 and the eccentric reciprocating mechanism 3 are simple in structural form and high in force transmission efficiency, the overall space of the data card mechanism is effectively saved, and the weight of the data card plugging mechanism is reduced. The maintenance is simple and reliable, and the implementation is convenient.
