Abstract

The invention discloses a card advancing and retreating device which comprises a shell, the shell is connected with a card in a sliding mode, the card advancing and retreating device further comprisesa fixed plate, the fixed plate is connected with a movable plate in a sliding mode, and a movable plate reset spring is arranged between the fixed plate and the movable plate. A fixed plate guide strip is fixedly arranged on the fixed plate, a guide strip slope is arranged at one end of the fixed plate guide strip, the movable plate is connected with a card locking unit, the card locking unit comprises a card locking spring, one end of the card locking spring is fixedly connected with the movable plate, and the other end is fixedly connected with a card locking and sliding block. A movable plate guide through hole is formed in the movable plate, and the first end of the locking and clamping sliding block penetrates through the movable plate guide through hole and abuts against the fixed plate guide strip. A second end of the card locking and clamping sliding block is fixedly provided with a card locking hook used for hooking the card. The card advancing and retreating device further comprises a locking driving piece, and the locking driving piece is in driving connection with a locking piece used for limiting movement of the movable plate. The card advancing and retreating devicecan automatically lock the card when the card enters, so that the deviation of the card is avoided.

Description

technical field [0001] The invention relates to the field of cards, in particular to an advancing and retreating card device. Background technique [0002] With the widespread use of various cards such as memory cards, devices for feeding / ejecting cards have also been developed. Common advance and retreat card devices include direct plug-in and spring-loaded type. The direct plug-in type is to manually force the card to be inserted and pulled out. Although it is widely used, the card is easy to be damaged during the plug-in process. The spring pressing type is to use springs and other components arranged in the advancing and retreating card device to eject the card when withdrawing the card, which avoids the disadvantages of forced pulling out. [0003] For example, a Chinese utility model patent 200520011709.8 discloses a connector advance and retreat card device, including a base and a spring hook on the base, a track seat and a bump on the track seat that engages with th...
