OPENING AND SHUTTING DEVICE FOR AUTOMATIC DOOR OF ACTIVE X-RAY SPECTROMETER

摘要

The present invention relates to a device for opening and shutting an automatic door to open and shut a gate of an active X-ray spectrometer including a box type shield case which is open at one side thereof and has a sample holder, an X-ray generator, and an X-ray detector mounted therein; and a gate for shielding the opening of the shield case to be opened and shut. The device for opening and shutting an automatic door includes: a driving motor fixed to an outer side of the shield case to provide a driving force; a first link having a bar shape including an end connected to the driving motor and an opposite end hinged to a top end of the gate so that the opposite end is pivoted based on the end to elevate the gate; and an elevation guider controlling an operation of the driving motor according to elevation of the gate while guiding the elevation of the gate. According to the present invention, the gate is controlled by a guide link and a switching member while opening and shutting the gate through the first link operated by the driving motor, thereby being stably elevated and exactly opened and shut by the switching member configured by first and second limit switches.
