Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a door mounting structure for a resin box for storing various electric devices and the like, which has an opening on a front surface of a main body and covers the opening with a door that can be opened and closed by a rotating operation.
[0002]
[Prior art]
The door mounting structure of the resin box in the prior art is such that both the hinges on the main body side and the hinges on the door side are integrally formed with the main body or the door body, so that it is easy to assemble and the door is opened and closed in a normal use state. The body was a structure that did not come off.
For example, as a first conventional example, as shown in FIG. 5, the main body side hinge 31 has a substantially cylindrical one end formed in a substantially U-shape, and the door body side hinge 32 is formed in a substantially L-shaped pin shape. The distal end has a notch 33 formed so as to be able to be inserted into the U-shaped part of the main body side hinge 31, and the groove 34 is formed so as to be hooked on the main body side hinge end 31.
Further, as a second conventional example, as shown in FIG. 6, an insertion hole 36 is provided in the main body side hinge 35, and a hooking projection is provided near a portion where the hinge pin 38 of the door body side hinge 37 is inserted. The door body side hinge 37 is formed with a notch 41 so that the hook projection piece 39 is inserted into the shaft wall 40 which holds the hinge pin 38 and is locked.
As a third conventional example, as shown in FIG. 7, a hinge shaft 43 of a main body side hinge 42 is formed by cutting a plate-shaped portion 45 in a circular body 44, and a door body side hinge 46 is formed by a plate of the main body side hinge 42. A notch 47 through which the shape portion 45 can be inserted is formed, and the body-side hinge 42 is inserted through the notch 47 and then slid, so that the circular portion 44 that has not been cut and formed is held by the door body-side hinge 46. There was one.
In addition, hinges as disclosed in Japanese Utility Model Laid-Open No. 4-36083, Japanese Utility Model Laid-Open No. 5-47277, and Japanese Utility Model Laid-Open No. 6-32659 have been used.
[0003]
[Problems to be solved by the invention]
However, in the three types of door mounting structures shown in FIGS. 5 to 7 in the above-described conventional technology, the door is held in a form in which a load is applied to the main body in the opening and closing operation of the door in a normal use state. Although the body was not detached, it did not come off. When these boxes are used outdoors, there is a risk that the doors will open due to gusts when not locked and are not provided with a function of preventing detachment, and may be blown away. In addition, the box in the conventional technology described above is exclusively for right-opening. If the box is to be left-opened due to installation space restrictions, if the box is turned upside down, the door body will fall off. Could not.
[0004]
[Means for Solving the Problems]
Therefore, an object of the present invention is to provide a door mounting structure that has a simple structure, the door does not easily come off due to an accident or the like, and the box can be mounted upside down. The structure consists of a hinge on the main body side on the main body, a hinge on the door body on the door body, a cutout on the hinge on the main body side, and a cutout on the hinge on the main body side on the door body hinge. A hinge shaft that can be inserted and fitted is formed, and a fall-prevention part that fits on the hinge shaft between the body-side hinge and the door-body-side hinge is provided. And a rotation-stopping piece that fits between them and a rotation-stopping piece that contacts the side surface of the door body.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
In the door of the box according to the present invention, the hinge on the body provided on the body is assembled with the hinge on the body provided on the body, and the door is attached to the body so as to be opened and closed by a rotating operation. After assembling the flat plate portion of the hinge on the main body side so as to face the notch of the hinge on the door body side, slide the door body to a position where it can be opened and closed, and fit the fall prevention component into the gap between the main body side hinge and the door body side hinge. The fall prevention component has a rotation stop protrusion and a rotation stop piece formed therein. The rotation stop protrusion fits between the end of the door body and the hinge shaft, and the rotation stop piece is a door body. Are fixed to the door body so as to stop the rotation of the fall-prevention parts.
[0006]
【Example】
An embodiment of a structure for attaching a door to a resin box according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0007]
The main body 2 of the resin box 1 is integrally formed with a hinge 3 on the main body side, and the door body 4 is integrally formed with a hinge 5 on the door body side. The body-side hinge 3 forms a cylindrical hinge portion provided with a notch 6 in only one direction on the side surface of the body 2 of the box 1, and a hinge shaft 7 of the door body-side hinge 5 has a cutout of the body-side hinge 3. A flat plate portion 8 is formed on a part of the cylindrical hinge shaft 7 so as to face the notch 6. Shaft walls 9 are provided at both ends of the hinge shaft 7 of the door body side hinge 5. The flat plate portion 8 of the hinge 5 on the door side is opposed to the notch 6 on the hinge 3 on the main body side, the hinge shaft 7 is inserted into the hinge 3 on the main body side, and the door body 4 is slid in the direction of arrow A in FIG. The door body 4 is attached to the main body 2 by facing the cylindrical portion of the hinge shaft 7 where the flat plate portion 8 is not formed so that the notch 6 of the main body side hinge 3 coincides with the flat plate portion 8 and does not fall off. It is mounted to be openable and closable by a rotating operation.
[0008]
The falling-off prevention component 10 forms a substantially U-shaped fitting portion 11, a rotation stopper convex portion 12 extending from the fitting portion 11, and a rotation stopper piece 13. After assembling the door hinge 5 to the main body hinge 3, the door 4 is moved in the direction of arrow A in FIG. Then, the fitting portion 11 of the drop-preventing component 10 is inserted into the gap between the main body hinge 3 and the door body hinge 5 to be fitted to the hinge shaft 7. The rotation stopper 13 of the fall-prevention component 10 abuts against the side surface of the back surface of the door 4 to prevent the fall-prevention component 10 from rotating.
[0009]
Usually, the door body is used with the right opening, but when using with the left opening, the main body is mounted upside down. Since the hinge is fixed by the fall prevention component 10, even when the hinge is turned upside down, the door body does not slide and the flat plate portion 8 faces the notch 6 and the door body does not come off. .
[0010]
The drop-prevention component 10 has a knob 14 on the opposite side of the rotation stopper 13 from contacting the door. The attachment / detachment of the falling-off prevention component 10 is performed by holding the knob portion 14. However, there is no need to remove the fall-prevention component 10 except for removing the door 4. In addition, since the fall-prevention component 10 is attached from the inside of the door body 4, the fall-prevention component 10 cannot be touched unless the door body 4 is opened.
[0011]
【The invention's effect】
As described above, in the door mounting structure for the resin box according to the present invention, the main body side hinge is formed on the main body, the door body side hinge is formed on the door body, and the main body side hinge is partially notched. Provided on the door hinge is a hinge shaft that can be inserted and fitted from the notch of the main body hinge, and a falling-off prevention part that fits on the hinge shaft between the main body hinge and the door body hinge is provided. In order to form a rotation-stop projection that fits between the end of the door body and the hinge shaft and a rotation-stopping piece that contacts the side surface of the door body, the flat plate portion of the door body-side hinge is The door does not slide to the position facing the notch of the hinge on the main body side, so that it is possible to prevent the door from being accidentally detached. Also, even if the box is turned upside down, the door body does not fall off or rattle, so the opening direction of the door body can be changed. spread.
