Abstract

PROBLEM TO BE SOLVED: To smoothly and quickly open the door of the main body case of an electric equipment enclosure after the pressure in the box is relieved. SOLUTION: A supporting body 19 is fixed to one internal side face of a main body case 1 and a through hole 19a is formed at the front end of the body 19. A sliding bar 20 is loosely passed through the hole 19a and a bracket 5 formed in a rectangular block is provided at the front end of the bar 20. A long hole 5a is formed at the center of the bracket 5 and a lock pin 4 is loosely inserted into the hole 5a. Double nuts 22 are engaged with the rear end of the bar 20 through a washer 21 and a compression spring 23 is put between the washer 21 and supporting body 19 in a state where the bar 20 passes through the spring 23. When the pressure in the case 1 suddenly rises owing to a short-circuiting accident, etc., and an opening/closing door 2 starts to open, the lock pin 4 is press-contacted with the bracket 5 against the pressure of the spring. Therefore, the press-contacting force of the pin 4 applied to the bracket 5 is relieved.

Next, a description will be given of the operation when the internal equipment in the main body case 1 suffers a short circuit accident or the like and the pressure in the main body case 1 suddenly rises. When the pressure in the main body case 1 suddenly rises, the pressure acts on the inner side surface of the opening / closing door 2 and the opening / closing door 2 tries to be opened. Then, the front end side of the lock pin 4 is pressed against the long hole 5a of the receiving metal 5,
The receiving fitting 5 is slightly pulled out in the opening direction of the opening / closing door 2 against the biasing force of the compression spring 23, and the opening / closing door 2 is opened. Then, the internal pressure is released from the opening 1 of the main body case 1 to the outside. At this time, the lock pin 4 is attached to the receiving fitting 5
Of the compression spring 23.
Is alleviated by Therefore, the lock pin 4 is not easily deformed by the pressure contact with the receiving fitting 5.

In addition, the pressure in the main body case 1 may rise more than expected, and a force exceeding the design value of the compression spring 23 may act on the opening / closing door 2, causing the lock pin 4 to be deformed. In this case, when the lock pin 4 is pulled out from the elongated hole 5a of the receiving fitting 5 when the opening / closing door 2 is opened after the pressure is released, the receiving fitting 5 is swung in the vertical and horizontal directions of the main body case 1. Therefore, the lock pin 4 is smoothly moved to the unlocked position. Further, the one lock pin 4 may be deformed so as to be bent in the left-right direction of the main body case 1.
In this case, since the clearance of the lock pin 4 with respect to the elongated hole 5a is sufficient in the left-right direction of the main body case 1, the lock pin 4 is smoothly moved to the unlocked position. Therefore, the lock pin 4 is moved to the unlocked position without any trouble, and the opening / closing door 2 can be reliably opened.
