  As shown in FIG. 11, the hinge structure of the present invention includes a hinge pin slide portion 7 that slidably supports a hinge pin 4 provided on the upper and lower ends of the door, and a pin receiving portion 5 provided on the box body 1. And a hinge securing structure of the box for detachable electrical equipment, wherein the hinge pin 6 of the synthetic resin forming the hinge pin slide portion 7 is provided with a clearance securing member between the box body 1 and the door 2. 14 is provided integrally.

That is, the door 2 is lowered by its own weight, and there is a case where the door 2 and the box body 1 are rubbed to generate an abnormal noise. A clearance securing member made of a synthetic resin, which is separately molded, is interposed so as to ensure a certain gap between them. On the other hand, in the present invention, as shown in FIG. 12, since the clearance securing member 14 is provided integrally with the hinge case 6, it is necessary to make the clearance securing member as a separate member as in the prior art. As a result, the number of parts can be reduced, and since a single operation for assembling only the clearance securing member does not occur, the assembly workability can be improved.
Further, by providing a clearance securing member above and below the hinge case 6 so that the hinge pin 4 can be exchanged between the hinge case 4 and the hinge pin 4 selectively, the hinge pin 4 can be selectively incorporated to be adapted to the upper and lower hinges.
In addition, 14a is a clearance ensuring member attached to the edge part of the door 2 at the side far from a hinge, and is the same as that of the past.

  As shown in FIG. 5, the clearance securing member 14 can be provided with a shaft support portion 14 b of the hinge pin 4 in the same manner as the shaft stopper 9 described later. This is preferable because the hinge pin 4 can be firmly supported without rattling. In the illustrated example, the shaft support portion 14b has a semicircular shape, but it is of course possible to have a circular shape.

A part of the shaft support 14b is provided with a protrusion 14c that protrudes into a space into which the door between the hinge case main body and the clearance securing member 14 enters. The protrusion 14c fits into the round hole of the door 2 to reliably fix the position of the hinge case 6 and prevent the metal between the hinge pin 4 and the door 2 from rubbing against each other.
Conventionally, a resin washer is used as a clearance securing member. However, in this case, since the hinge pin 4 is simply passed, the washer is removed when the hinge pin 4 is removed and the door 2 is removed. Although there was a problem of dropping and losing, in the case of the shaft support portion 14b, there is no fear, and excellent workability can be exhibited.

Further, in the hinge structure of the present invention, as shown in FIGS. 5 to 10, the hinge case 6 is of a two-part type.
That is, the conventional hinge case is formed by bending a plate material to form a slide member, which is incorporated into the case to form a hinge pin slide portion, and there is a problem that the assembly work is troublesome. The cylindrical hinge pin slide part 7 can be easily formed by uniting the hinge cases 6 and 6 formed together. In the figure, reference numeral 4a denotes an operating portion that is suspended from the hinge pin 4 and is a separate member from the pin main body, but it may be of an integrated type or L-shaped.

The hinge case 6 is made of a synthetic resin such as polypropylene, and receives the hinge pin 4 with a semicircular arc-shaped shaft stopper 9 having a longer distance than the diameter of the hinge pin 4 extending in the axial direction. . In addition, an elastic member 8 such as a coil spring that constantly urges the hinge pin toward the side protruding from the hinge case is disposed on the rear end side of the hinge pin 4.
In this way, the hinge pin 4 is always urged toward the side protruding from the hinge case 6 so that the door 2 is always stably attached, and the hinge pin 4 is fixed to the diameter of the hinge pin 4 of the shaft stopper 9. By holding in a block shape at a longer distance, stable holding can be performed.

Further, the long hole 10 through which the operation portion 4a of the hinge pin 4 slides is formed when the hinge case is combined by a notch provided in the end surface of the divided hinge case 6. That is, the long hole 10 is formed in the mating portion 11 of the hinge case 6. Thereby, the assembly | attachment of the hinge pin 4 can be performed easily.
In addition, 10a is the bending part which latches the operation part 4a in a predetermined position, may be integrally molded, may be shape | molded by another member, and may be provided above and below the long hole 10. FIG.

  Further, as shown in FIG. 12, a long hole 10 through which the operation portion 4 a of the hinge pin 4 slides can be provided on a side surface adjacent to the mating portion 11 of the hinge case 6.

Further, it is preferable to provide a hinge pin holding projection 10b for holding the hinge pin 4 in a protruding state in the long hole 10 of the hinge case 6. By locking the operating portion 4a of the hinge pin 4 with the hinge pin holding projection 10b, the protruding state of the hinge pin 4 can be reliably held, and the door 2 can be prevented from falling off.
Note that the elastic member 8 may be omitted if a mechanism for holding the hinge pin 4 in a protruding state, such as the hinge pin holding protrusion 10b, is provided.

  Furthermore, the long hole 10 can also be provided in two opposing surfaces of the hinge case 6. In this case, at the time of assembling, the hinge pin 4 can be applied to either the upper or lower hinge by selecting and incorporating any one of the long holes 10. It can be managed with parts, which is preferable.

In addition, since the hinge cases 6 and 6 divided into two are connected and formed integrally by the thin-plate part 12, they can be manufactured and managed as one member, and it is convenient.
Since the thin plate portion 12 is provided so as to fit within the rectangular parallelepiped of the hinge case 6 when the hinge cases 6 and 6 are integrated, the thin plate portion 12 has good fit when the hinge case 6 is attached to the door 2. The part 12 may protrude from the side surface of the hinge case 6 when the hinge cases 6 and 6 are integrated.
Further, the hinge cases 6 and 6 divided into two instead of the thin plate portion 12 may be connected and integrated by a general elastic locking claw (not shown).

It is preferable to provide the opening 2a of the U-shaped bent portion at the side end of the door 2 so that the end of each hinge case is disposed. As a result, when the hinge case divided into two parts is integrated and fitted into the U-shaped bent portion 2a of the door, the hinge case is supported from both sides. Even when force is applied to the hinge 6, the hinge case is not separated, and the hinge is not damaged.
Further, as shown in FIG. 2, the hinge case 6 is attached to the protruding side of the hinge pin 4 of the hinge case 6 so that the hinge case 6 is attached to the U-shaped bent portion at the side end of the door 2. Since the threaded portion 6b is provided on the rear end side of the pin 4, it can be easily performed with only one screw 13 on the bent wall 2b of the door 2, which is convenient.
It should be noted that the attachment locations may be elastic locking claws on both sides, and in that case, it is preferable that the extending directions of the respective elastic locking claws are different by 90 °. You may make it engage by deformation | transformation of door itself as a protrusion which does not deform | transform an elastic latching claw.

Next, the attachment of the hinge of the present invention will be described.
First, as shown in FIGS. 6 to 7, the hinge cases 6, 6 formed by dividing into two parts are opened, and the hinge member 4 and the elastic member 8 made of a coil spring are set therein. Next, as shown in FIG. 5, the hinge cases 6 and 6 are closed and integrated to form a quadrangular columnar hinge case 6 in which the hinge pin 4 is housed. In this case, the hinge pin 4 and the coil spring are simply mounted on the hinge cases 6 and 6 in an open state, and can be easily and accurately performed.

Next, as shown in FIG. 4, with the hinge pin 4 retracted, the hinge case 6 is fitted into the opening 2a of the U-shaped bent portion at the door side end. In this case, it arrange | positions so that the operation part 4a of the hinge pin 4 may come to the place where it is easy to operate. For example, when the side end portion of the door 2 is a U-shaped bent portion as in this embodiment, the clearance securing member 14 is overlapped on the upper and lower bent portions of the door 2 before the opening 2a, and then the hinge The case 6 is fitted into the U-shaped bent portion of the door 2. In addition, when the side edge part of the door 2 is a simple bending part like an up-and-down part, it will arrange | position to a corner part. Thereafter, as shown in FIG. 2, it can be easily attached to the bent wall 2 b of the door 2 with only one screw 13.
As a result, the hinge case is supported from both sides, so that even if force is applied to the door 2 or the hinge case 6, the hinge case will not be separated, and the hinge will not be damaged.

After the hinge case 6 is attached, as shown in FIG. 3, the hinge pin 4 is slid outward to project the hinge pin 4 from the upper end surface of the door 2, and this is connected to the pin receiving portion 5 on the box body side. The door 2 can be rotated.
At this time, the hinge pin holding projection 10b is provided in the elongated hole 10 of the hinge case 6, and the operation portion 4a of the hinge pin 4 is firmly engaged, so that the hinge pin 4 does not fall down and the door 2 is surely secured. Therefore, the operation moderation and workability can be improved.
In such an embodiment, the hinge case 6 is divided in the axial direction of the hinge pin 4. However, the hinge case 6 may be divided above and below the axis, or may be inclined with respect to the axis.

The case where the hinge is attached to the upper end portion of the box body 1 has been described above, but it goes without saying that the same can be applied to the case where the hinge is attached to the lower end portion of the box body 1.
On the other hand, the procedure for removing the hinge is not described because it is only necessary to perform the reverse operation of the above attachment procedure.

  As is clear from the above description, the present invention has a structure in which a clearance securing member between the box body and the door is integrally provided in the synthetic resin hinge case forming the hinge pin slide portion. In addition, it is not necessary to create a clearance securing member as a separate member, the number of parts can be reduced, and a single work for assembling only the clearance securing member does not occur, so that the assembly workability can be improved.
