Description

  The present invention relates to a door body mounting structure for a resin box for housing various electric devices including a main body having an opening on the front surface and a door body that covers the opening.

  In order to improve the waterproof and dustproof function of the resin box, conventionally, packing has been pasted on the back surface of the door body. However, there is a drawback in that the work for sticking the packing takes time and the number of parts increases, resulting in an increase in manufacturing cost.

In view of this, ribs are provided alternately on the outer periphery of the back of the door, the peripheral edge of the opening of the main body, and the draining portion to prevent foreign matter from entering the box.

  In the resin box provided with the rib, since the position of the hinge shaft is fixed, the rib interferes when the door body is opened and closed, and the door body may not be closed well.

  An object of the present invention is to provide a resin box door mounting structure having a simple structure and good assembling workability, and the structure of the opening peripheral edge of the main body so as to fit each other when the door body is closed. The door body is provided with ribs, the main body has a substantially U-shaped hinge on the main body, and the door body has a hinge on the door body that can be fitted to the hinge on the main body side. The door body is pivotably mounted with a combination of and a receiving part is provided at the end of the hinge on the main body side, and a convex part is formed at a position facing the receiving part of the hinge on the door side. The position of the hinge shaft can be changed by riding on the receiving portion.

  Further, the door body side hinge is provided with a locking piece, and when the door body is in a closed state, the locking piece is locked to the main body side hinge.

  The resin box door mounting structure according to the present invention is provided with ribs on the opening peripheral edge of the main body and the door body so as to fit each other when the door body is closed, and the main body has a substantially U-shaped cross section. A hinge on the door and a hinge on the door that can be fitted to the hinge on the main body are formed on the door, and the door is pivotably mounted by combining the hinge on the main body and the hinge on the door, and the end of the hinge Since the convex part is formed at the position facing the hinge receiving part on the door body side, the assembly workability is good, and the hinge shaft position is variable when the door body is opened and closed, so that the door body can be opened and closed. There is an advantage that it becomes smooth.

  In addition, the door-side hinge is provided with a locking piece, and when the door is closed, the locking piece is locked to the body-side hinge, so that the hinge part can be prevented from rattling.

  The present invention achieves the purpose of smoothly opening and closing the door without requiring any special work in production and without impairing the waterproof and dustproof performance.

  An embodiment of a resin box door mounting structure according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The resin box 1 according to the present invention is configured by covering a main body 3 having an opening 2 on the front surface and a door 4 with the opening 2. The door body 4 is hinged to the main body 3 and can be opened and closed by a rotating operation. A draining portion 5 is bent at the periphery of the opening 2 of the main body 3 to prevent rainwater and solid matter from entering. Ribs 6 are provided at the draining portion 5 and the hinge-side end of the door body 4, and when the door body 4 is closed, the ribs 6 are alternately fitted to further prevent rainwater and solid matter from entering.

  A main body side hinge 7 is formed on the main body 3, a door body side hinge 8 is formed on the door body 4, and the main body side hinge 7 and the door body side hinge 8 are combined to attach the door body 4 to the main body 3. The main body side hinge 7 is formed in a U-shaped cross section and is provided with a notch 9. The door-side hinge 8 forms a shaft 10 that can be inserted into the body-side hinge 7 from the notch 9 and a stopper 11 that restricts the movement of the door-side hinge 8 at both ends of the shaft 10.

  A receiving portion 12 is formed on the main body side hinge 7, and a convex portion 13 is formed at the end of the shaft 10 of the door side hinge 8 so as to face the receiving portion 12. When the door body 4 is closed from the opened state, the door body side hinge 8 rotates in the main body side hinge 7, the convex portion rides on the receiving portion 12, and the door body 4 moves outward. Therefore, the door body 4 can be closed without the rib 6 provided at the hinge side end of the door body 4 interfering with the rib 6 provided in the main body draining portion 5.

  A locking piece 14 is provided at the end of the door-side hinge 8 so that when the door body 4 is in a closed state, the locking piece 14 is locked to the body-side hinge 7 to suppress the rattling of the hinge part. .

  When opening and closing the door body, the hinge on the body side has a margin compared to the shaft diameter of the hinge on the door body side so that the hinge does not come off even when the convex part rides on the receiving part. It can also be applied to cases where it is not desired to generate unusual noises such as rubbing hinges.

It is a perspective view which shows a resin box. (Example 1) It is a side view of the hinge part which shows the door body attachment structure of resin boxes. (Example 1, Example 2) It is sectional drawing of the hinge part which shows the door body attachment structure of resin-made boxes. (Example 1) It is explanatory drawing which shows operation | movement of the hinge part of resin-made boxes. (Example 1, Example 2) It is a door body reverse view which shows the conventional resin box. It is a partial sectional view showing a conventional resin box.
