Field of the Invention An electric device such as a main breaker or a branch breaker is mounted on a base, and a wiring portion connecting the electric devices of the base is covered with a cover. The present invention relates to a hinge structure of a distribution board comprising a cover and a hinged door rotatably. 2. Description of the Related Art As shown in FIG. 5, in a power distribution panel 21 with a door according to the prior art, a cover 23 of the power distribution panel 21 is held on a cover 23 so that the door 22 can be held in the state when the door 22 is fully opened. A leaf spring 24 is attached, a receiving portion 25 that comes into contact with the leaf spring 24 is formed on the door 22, and a lock portion 26 is formed at an end of the receiving portion 25. The locking portion 26 is locked to a locking portion 27 formed by bending the leaf spring 24 so that the door 22 can be held in that state when the door 22 is fully opened. [0003] However, in the distribution board 21 in the above-mentioned prior art, the door 22 has the locking portion 27.
At that point, the force of the leaf spring 24 acts in the direction of arrow B, and the direction is the direction of closing the door. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a hinge structure of a distribution board which can be opened and closed gently with a simple structure. A leaf spring is attached to the inside of the cover so that it can move, and an arc-shaped friction part that slides on the leaf spring when the door is turned and an end of the friction part are attached to the end of the door. It is characterized in that a lock portion that can be locked to a leaf spring is formed. [0005] In the hinge structure of the distribution board according to the present invention, a leaf spring is attached to the cover, and a friction portion is formed at a portion of the door that comes into contact with the leaf spring. The leaf spring bends and acts to push the door outward. The end of the friction portion is a lock portion, and when the door is opened to the maximum, the lock portion comes into contact with the leaf spring and can be held in that state. Further, when the door is closed, the friction portion slides on the leaf spring, and the lock portion gently climbs over the leaf spring in accordance with the arc of the friction portion and can be closed quietly. An embodiment of a hinge structure of a distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS. In a power distribution board 1 according to the present invention, electric equipment such as a main breaker and a branch breaker is mounted on a base 2 and a cover 3 is provided.
To cover the wiring of electrical equipment, etc., and further cover the door 4 with 3
, And is mounted so as to be openable and closable by a rotating operation. A friction portion 5 is formed near a portion where the door 4 is fixed to the cover 3 and a lock portion 6 is formed at an end of the friction portion 5. The friction part 5 is formed in an arc having a diameter equal to the distance from the hinge shaft 7 to the lock part 6. The cover 3 has a receiving portion 8 protruding therefrom.
The leaf spring 9 is attached to the. The leaf spring 9 is formed in a curved shape, and a force for pressing the door 4 in the direction of arrow A in FIG. When the door 4 is opened to the maximum, the locking portion 6 of the door 4 comes into contact with the locking portion 10 of the leaf spring 9 and the door 4 is opened. It is kept in the state where it was done. When the door 4 is closed, the leaf spring 9 is closed.
While the friction part 5 of the door 4 slides on the upper part, the lock part 6 comes off from the locking part 10 of the leaf spring 9. At this time, since the friction portion 5 has an arc shape, the lock portion 6 of the door 4 is gently disengaged from the locking portion 10, so that the door 4 does not close vigorously. Further, as in the modified embodiment shown in FIG. 3, the diameter of the arc of the friction portion 12 formed on the door 11 is not particularly limited, but is formed to be large to reduce the friction with the leaf spring 13. By increasing the size, the door 11 may be held in an open position at an arbitrary position, in addition to the lock portion 14 provided at the end of the friction portion 12. As shown in FIG. 4, the door 15 has a friction portion 17 which slides on a leaf spring 16 in an arc shape.
A component 20 having a lock portion 19 abutting on a locking portion 18 formed by bending the plate spring 16 can also be attached. By preparing a variety of parts having different diameters of the arc of the friction portion 17 and attaching them to the door 15, the open / close state of the door can be adjusted. As described above, in the hinge structure of the distribution board according to the present invention, the door is rotatably fixed to the cover by the cover.
A leaf spring is attached to the inside of the cover. At the end of the door, an arc-shaped friction portion that slides on the leaf spring when the door is turned, and the leaf spring can be locked at the end of the friction portion. Since the lock portion is formed, the door can be opened and closed gently and can be safely opened and closed. When the diameter of the circular arc of the friction portion formed on the door is increased, the friction between the leaf spring and the door increases, and temporary holding at an arbitrary position becomes possible.
