  However, the conventional box for storing electrical equipment is formed so that the door body fits in the frame portion of the box body, and when the door body is opened, the front surface of the door body is at the corner of the frame portion. There was a drawback that the front face hit and scratched.

According to the first aspect of the present invention, there is provided a box having an opening on the front surface and a hinge provided on both upper and lower ends so as to be accommodated in a frame formed in the front opening of the box. A box for storing electrical equipment comprising a door body that can be freely opened and closed. The horizontal plate portion of the hinge bracket is provided with a projecting piece so as to project outward from the door body, and the door body is opened at a predetermined angle. In this case, the hinge protrusion is brought into contact with the protrusion receiving portion formed on the frame of the box so that the door cannot be opened more than a predetermined angle.

  According to the first aspect of the present invention, when the door body is opened, the front surface of the door body can be prevented from coming into contact with the frame portion of the box body and being damaged, and the projecting piece is formed as a hinge. Therefore, even when the plate thickness of the box is reduced, the strength of the projecting piece can be ensured, and deformation of the projecting piece can be prevented.

The electrical equipment storage box which concerns on this invention is shown, (a) is a front view, (b) is a right view. It is a front view of a door body. It is the A section enlarged view of FIG. It is a front view of a box. It is the B section enlarged view of FIG. It is a cross-sectional view of the electric equipment storage box in a state where the door is closed. It is a cross-sectional view of the electric device storage box with the door opened. It is the C section enlarged view of FIG.

  The electrical equipment storage box is a box having an opening at the front, and a door that can be opened and closed by a hinge provided at both upper and lower ends so as to fit in a frame formed at the front opening of the box. The hinge is provided with a projecting piece projecting from the door body, and when the door body is opened at a predetermined angle, the hinge projecting piece comes into contact with the projecting piece receiving portion formed in the frame of the box body, and the door body is predetermined. Avoid opening more than an angle.

  A first embodiment of an electric equipment storage box according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The electric equipment storage box 1 is composed of a box 2 having an opening on the front surface, and a door 8 that is provided at the front opening of the box 2 so as to be opened and closed by a hinge 10.

  The door body 8 is provided with hinges 10 and 10 above and below one of the left and right edges, and a handle 15 is provided at the other edge.

  The hinge 10 is formed in a substantially U shape by a hinge pin 11 that becomes a shaft portion when the door body 8 is opened and closed, a base portion 12a, and horizontal plate portions 12b and 12b that are bent at both ends thereof, and both horizontal plate portions 12b. The hinge 12 is inserted and held in the hole 12c formed in the hole 12c, and the spring 13 biases the hinge pin 11 in a direction protruding from the hinge 12. The hinge pin 11 is inserted into the hole 12c of one horizontal plate portion 12b of the hinge metal fitting 12 and subsequently inserted into the spring 13 to prevent the hinge pin 11 from coming off with the E-ring 14, and the tip of the hinge pin 11 is connected to the other horizontal plate. The hinges 10 and 10 are attached to the top and bottom of the door body 8 so that the tip of the hinge pin 11 protrudes from the top and bottom of the door body 8 by being inserted into the hole 12c of the portion 12b. The tip of the hinge pin 11 is retracted into the door body 8 against the force of the spring 13 by pulling the knob 11a at the rear end of the hinge pin 11 backward. Further, a projecting piece 12 d is formed on the horizontal plate portion 12 b of the hinge fitting 12 that holds the distal end side of the hinge pin 11 so as to project outward from the door body 8.

  Further, the box body 2 is bent in a U-shape around the entire front opening, and is further bent in an L-shape in the inner direction to form a frame portion 2a so that the door body 8 is accommodated in the frame portion 2a. It has become. A shaft hole 2b through which the hinge pin 11 of the hinge 10 is inserted is formed in both upper and lower portions of the frame 2a. The hinge pin 11 of one hinge 10 of the door body 8 is fitted into the shaft hole 2b, and the other When the hinge pin 11 of the hinge 10 is pulled into the door body 8 by pulling the knob 11a, the hinge pin 11 and the shaft hole 2b are aligned. The door body 8 is detachably attached to the box body 2 by being inserted into the box body 2. Further, a hole through which the projecting piece 12d of the hinge 10 is inserted is formed in both the upper and lower parts of the frame 2a, and the projecting piece receiving part is brought into contact with the projecting piece 12d when the door body 8 is opened at a predetermined angle at the edge of the hole. 2c is formed. The shaft hole 2b and the projecting piece receiving portion 2c are formed on both the left and right sides so that the opening direction of the door body 8 can be changed.

  In the electrical equipment storage box 1 configured as described above, when the door body 8 is opened at a predetermined angle, the projecting piece 12d of the hinge 10 contacts the projecting piece receiving portion 2c of the box body 2, and the door body 8 is predetermined. Since the gap a is provided between the front surface of the door body 8 and the frame portion 2a of the box body 2 so that it cannot be opened more than an angle, the front surface of the door body 8 is in contact with the frame portion 2a of the box body 2. It is possible to prevent the front surface of the door body 8 from being damaged. Further, since the protrusion 12d is formed on the hinge 10, even when the box 2 is thin, the strength of the protrusion 12d can be ensured and deformation of the protrusion 12d can be prevented.

  In the present embodiment, the protruding piece is formed on the horizontal plate portion of the hinge metal fitting of the hinge, but the present invention is not limited to this, and the protruding piece receiving portion of the box also has a hole through which the protruding piece is inserted into the frame portion. The projecting piece comes into contact with the edge of the hole, but the projecting piece receiving part is formed so that the projecting part comes into contact with the cutout part of the frame part. The shape and structure of the box, hinge, and door may be changed as appropriate without departing from the spirit of the present invention.
