Safety door device of self-service library

Abstract

The invention discloses a safety door device of a self-service library. The safety door device comprises a mounting groove located between a soil layer and a wall. A rectangular channel is formed in the wall and internally provided with a fixed door, a sliding rail and a movable door, and a single-sided rack is arranged on the movable door; a control box is fixedly arranged on one side of the topof the channel; and the mounting groove is internally provided with a driving mechanism and an enlarging mechanism. According to the safety door device of the self-service library, through a structurecomposed of two incomplete gears and a double-sided rack in the driving mechanism, a motor rotates in one direction, thus reciprocating movement of the double-sided rack can be realized, and then opening and closing of the movable door are realized; and in addition, the first incomplete gear is engaged with the second incomplete gear and the double-sided rack alternately, so that the double-sidedrack stops for a certain time at the two ends of the movement travel while reciprocating movement of the double-sided rack is realized, accordingly, the time period is obtained from complete openingof the movable door to the next time of closing, and the safety protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of safety doors, in particular to a safety door device of a self-service library. Background technique [0002] The emergence of self-service libraries has brought many conveniences to our lives. Not only can we borrow or return books 24 hours a day, but we don’t have to worry about the distance to the library. This also increased everyone's enthusiasm for reading and triggered a reading craze. With the increase in the number of reading and borrowing books, the doors of the self-service library will inevitably increase the frequency of opening and closing, while most of the existing doors are controlled by the positive and negative rotation of the motor, and the frequent positive and negative alternation of the motor is easy to cause damage to the motor , and for the opening and closing of the door, especially when the door is opened and then closed, there needs to be a certain intermittent time for safety,...
