Security Door Devices for Self-service Libraries

Abstract

The invention provides a safety door device of a self-service library, which comprises a first control door and a second control door arranged adjacently. The first control door includes a first revolving door, a first door frame, a first support, a first motor, a first limit switch and a trigger; the second control door includes a second revolving door, a second door frame, and a second support , the second motor, the second limit switch and the extension piece arranged at the end of the second support piece; the motor is installed on the support piece, the trigger piece is installed on the top of the motor, the revolving door is connected with the door frame in rotation, and the trigger piece rotates with the motor to The preset limit position is in contact with the limit switch; the extension piece at the end of the second support is rotated with the motor to the preset limit position and is in contact with the second limit switch; the first limit switch and the second limit switch alternate layers status settings. The invention can increase the book storage capacity of the self-service library, and at the same time avoid the damage of the motor and structural parts caused by the limitation of the width of the automatic door and the improper operation of the readers.

Description

technical field [0001] The invention relates to the field of self-service libraries, in particular to a safety door device for 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. [0003] However, for the safety door device of the self-service library, the thickness of the circulation audience books is relatively thin, and in order to store more books, this requires that the internal structure of the safety door device must be reasonable and compact. But in this case, it is very likely to increase the possibility of phenomena such as pinching hands and books due to misoperation or improper operation. At the same time, the safety door device will burn out the motor due to continuous external...

Problems solved by technology

[0003] However, for the safety door device of the self-service library, the thickness of the books in circulation is relatively thin, and in order to store more books, this requires that the internal structure of the safety door device must be reasonable and compact.

But in this case, it is very likely to increase the possibility of pinching hands and books due to misoperation or improper operation.

At the same time, the motor of the safety door device will burn out due to continuous external force interference, or even more serious consequences
