Claims

[Claims for Utility Model Registration] [1] A pair of hinges 14 and 16 are arranged in a vertical relationship on one side edge of the opening 10a of the casing 10, and a pivot point is provided perpendicularly to the hinges 14 and 16. By inserting the supporting pins 17 and 18 into respective through holes correspondingly drilled in the opening/closing door 12, the opening/closing door 12 can be closed.
In the pivot structure of the opening/closing door configured to pivot so as to be able to open and close freely, the pivot pin 18 protruding from the lower hinge 16 includes:
A vertical groove 24 extending in the axial direction and a circumferential groove 28 extending in the circumferential direction are bored, and the vertical groove 24 and the circumferential groove 28 are connected to each other via a tapered groove 30 having a downward slope in the direction of the longitudinal groove 24. A regulating plate 20 is disposed in the opening/closing door 12, through which a pivot pin 18 is inserted and rotates integrally with the door. When fully closed, it faces into the longitudinal groove 24 of the pivot pin 18, and
A pivot structure for an opening/closing door, characterized in that a guide piece 26 is provided in a protruding manner to move while being guided by the vertical groove 24, tapered groove 30, and circumferential groove 28 as the door 12 is opened and closed. [2] The circumferential groove 28 is bored in a required angular range around the axis of the pivot pin 18.
The end opposite to the end communicating with the tapered groove 30 of No. 8 comes into contact with the guide piece 26 when the opening/closing door 12 is opened at a required angle, thereby regulating the opening of the door 12. The pivot structure of the opening/closing door described in Item 1.
