The stopper pin 6 is fitted to the shaft groove of the stopper plate 6 provided at one end of the pivot pin 3 so as not to come off from the shaft cylinder portion 9 at all times, and the split groove 4 at the other end. The transverse pin 8 is fitted into the hole 5 and the axial hole 7 of the pivot pin 3, and the main portion of the stopper plate 6 is split so that the longitudinal axis of the stopper plate 6 is aligned with the longitudinal axis of the pivot pin 3. When housed in the groove 4, the stopper plate 6 enters the inner surface of the extension of the peripheral surface of the pivot pin 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge pivot pin used for an inner door of a switchboard storage box or the like.

[0002]

2. Description of the Related Art In a conventional removable hinge, a pair of blades are rotatably connected by a shaft rod, a cap is provided on the upper end of the shaft by a header process, and a cap nut is screwed on the lower end. The insertion / removal prevention portion is provided by fitting the. However, with the detachable hinge configured as described above, it is not easy to reduce costs such as thread cutting, and there is a risk that the nut may fall off or be lost during use.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a detachable hinge in which the shaft rod can be easily inserted / removed by one-touch operation, and the nut can be prevented from being lost / lost and the processing cost can be reduced. is there.

[0004]

In the following, with reference to the reference numerals in the accompanying drawings, in the removable hinge of the present invention, a shaft tube portion 9 is provided at the base end portions of the fixed side blade 1 and the rotating side blade 2. Provided at one end of the pivot pin 3 fitted into the shaft tube portion 9 is a drop-out preventing portion 10 so as not to always come off from the shaft tube portion 9, and a split groove 4 is provided at the other end of the pivot pin 3. And a stopper plate 6 provided in the diametrical direction and having a shaft hole 5 bored in the split groove 4, and crossed the shaft hole 7 bored in the split groove 4 of the pivot pin 3 and the shaft hole 5 of the stopper plate 6. When the main portion of the stopper plate 6 is housed in the split groove 4 so that the pin 8 is fitted and the longitudinal axis of the stopper plate 6 is aligned with the longitudinal axis of the pivot pin 3, the stopper plate 6 is Enter the inner surface of the extension of the peripheral surface of the pivot pin 3.

[0005]

Operation: To connect the rotating side blade 2 and the fixed side blade 1,
The main portion of the stopper plate 6 is housed in the split groove 4 so that the longitudinal axis of the stopper plate 6 is aligned with the longitudinal axis of the pivot pin 3. In this state, since the stopper plate 6 is located inside the extension of the outer peripheral surface of the pivot pin 3, the insertion of the pivot pin 3 into the shaft tube portion 9 is smoothly performed without being obstructed by the stopper plate 6. .

When the pivot pin 3 is fully inserted and the split groove 4 projects below the shaft tube portion 9, the stopper plate 6 is rotated about the transverse pin 8 to move the stopper plate 6 in the longitudinal direction. The stopper plate 6 projects outside the extension of the outer peripheral surface of the pivot pin 3 by making the axis line and the axis of the pivot pin 3 in the longitudinal direction at right angles. The stopper plate 6 and the stopper plate 6 come into contact with the shaft tube portion 9 to be blocked.

When the pivot pin 3 is pulled out, the stopper plate 6 is rotated so as to be housed in the extension of the outer peripheral surface of the pivot pin 3, and the drop-out prevention portion 10 at the upper end of the pivot pin 3 is pulled up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a fixed side vane 1 is attached to a body fitting 11 fixed to an inner wall 18 of a switchboard box or the like via a washer 12 and a spring washer 13.
4 and is fixed to the rotary vane 2 by screws 1
The door 17 is fixed by 6 and the interval between the inner wall 18 and the door 17 can be changed by the elliptical through hole 15 provided in the main body fitting 11.

Spring pins are used for the axial holes 7 of the split groove 4 of the pivot pin 3 and the transverse pin 8 pivotally attached to the axial hole 5 formed in the stopper plate 6, and the split groove 4 of the pivot pin 3 is used. By crushing the split groove 4 in the vertical direction, the stopper plate 6 is rotated by receiving an appropriate resistance.

[0010]

As described above, in the pivot pin with stopper plate of the present invention, the stopper plate 6 fitted in the vertical split groove 4 of the pivot pin 3 is eccentric to pivot the pivot pin 3 with the horizontal transverse pin 8. When the stopper plate 6 is attached and the stopper plate 6 is projected and rotated to the horizontal position, the pivot pin 3 is prevented from falling off, so that the pivot pin 3 can be easily inserted and removed with one touch.

Further, since the stopper plate 6 is always connected to the pivot pin 3, there is no problem of dropping and loss during use unlike the conventional cap nut. Furthermore, since costly processing steps such as header processing and thread cutting processing are not included, the cost of the entire hinge is reduced.
