Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a rainproof outlet installed on an outer wall surface or the like.

[Background Art] In conventional rainproof electrical outlets, the plug holder is formed so that its angle can be adjusted freely, and when attaching or removing the plug to the plug holder, the plug holder must be manually rotated upward. However, if you forget to press down on the stopper receiver, there was a problem that water would flood through the insertion surface of the stopper receiver, which was oriented upward.

[Purpose of the invention] The present invention was provided in view of the above-mentioned points, and it prevents water from entering the stopper part by automatically pushing down the stopper part, and also prevents water from entering the stopper part when the hands are wet. It is an object of the present invention to provide a rainproof outlet in which the plug can be easily inserted into the insertion surface of the plug receptacle even when the plug is inserted.

[Disclosure of the invention] Hereinafter, embodiments of the invention will be described with reference to the drawings. In the figure, 2 is an outlet base that is attached to a wall through a waterproof gasket 6, and 4 is a plug holder into which the plug blade 23 of the plug 3 is inserted, and this plug holder 4 has a substantially triangular cross section. It has an insertion surface 4 on the bottom.
a, and plate-shaped pivot pieces 11 are formed on both sides of the tapered upper part. Reference numeral 10 denotes a holding frame for rotatably supporting the stopper holder 4, which has a U-shaped recess 12 on both sides, in which the stopper holder 4 is pivotably supported. Piece 11 is inserted. and,
Insert the core rods 13 and 14 from both sides into the insertion hole 1 of the holding frame 10.
7, 16, are inserted into the through hole 18 of the pivot piece 11 and screwed, so that the plug receiver 4 is rotatably supported around the core rods 13, 14 as fulcrums. and,
A coiled return spring 5 is interposed in one of the core rods 13, and the return spring 5 constantly urges the stopper holder 4 toward the wall 1 side. In other words, the insertion surface 4a of the stopper receptacle 4 is always urged downward. Note that this holding frame 10 is attached to the outlet base 2 with screws 24.

Furthermore, a plate-shaped push-up lever 15 is rotatably mounted in the center of one of the recesses 12 of the holding frame 10 via a pin 19 . This pin 19 is connected to the hole 25 in the approximate center of the push-up lever 15 and the holding frame 1.
The push-up lever 15 is inserted into the holding frame 10 by passing through the hole 26 of 0. A push button 21 is rotatably attached to the upper end of the push-up lever 15 by a pin 20, and this push button 21 protrudes from the upper part of the outlet base 2 toward the front side. Further, a roller 22 is rotatably supported on the lower end of the push-up lever 15, and this roller 22 is in contact with the back surface of the stopper holder 4. By the way, the plug receiving part 4 is the plug 3
It has a built-in blade holder spring for receiving the plug blade 23, and has a drip-proof structure with waterproof packing.
8 is a lead wire connected to a power source. Side walls 7 are integrally erected on both sides of the outlet base 2 in correspondence with the side surfaces of the plug receptacle 4. In other words, this type of rainproof outlet is installed at an appropriate height on the outside wall surface, and is therefore designed to prevent damage to the plug holder 4 caused by children's mischief. It is also used to prevent water from entering from the outside. Note that 9 is a mounting screw.

As shown by the solid line in FIG. 1, when not in use, the plug receptacle 4 is pressed against the wall 1 side by the biasing force of the return spring 5, and the insertion surface 4a faces downward. At this time, the roller 22 is pressed against the wall 1 by the stopper holder 4, and the push button 21 protrudes toward the front side. Next, when inserting the plug 3, when the push button 21 is pressed, the push-up lever 15 rotates about the pin 19, and the roller 22 rotates and urges the plug receiver 4 upward, and the plug receiver 4, orient the insertion surface 4a diagonally.
When the plug 3 is inserted and the push button 21 is released, the plug holder 4 is returned to its original position by the return spring 5, and the insertion surface 4a of the plug holder 4 faces downward to prevent rainwater from entering. . Here, push button 21
The reason for pushing the stopper is that if you hold the insertion surface 4a of the stopper holder 4 and rotate the stopper holder 4, there is a risk of electric shock. By pressing the button 21, the risk of electric shock can be further reduced. Note that the push button 21 may be located at the lower part of the outlet base 2. In addition, since the insertion surface 4a of the stopper holder 4 and the push button 21 are located apart from each other, operation is easy.

[Effects of the invention] As described above, the present invention includes an outlet base that is attached to a wall, a drip-proof plug receptacle with a plug insertion surface on the lower surface, and a plug receptacle that covers both sides of the plug receptacle. A side wall formed on both sides of the outlet base, a rotation shaft that pivotally supports the upper part of the plug holder and is rotatably supported with respect to the outlet base, and a plug holder that is held by the rotation shaft. A holding frame is disposed across the upper part of the housing in the width direction, and the holding frame is pivotally supported by a rotating shaft at one end of the holding frame to urge the stopper holder toward the wall and to force the insertion surface of the stopper holder downward. a push-up lever that is rotatably supported on the other end of the holding frame by a rotation shaft and that rotates the stopper receptacle upwardly on the insertion surface against the biasing force of the return spring; It is equipped with a push button that is rotatably supported at one end of the push-up lever and drives the push-up lever, so when the plug is not inserted into the stopper holder, the stopper holder is moved toward the wall by the return spring. Since the insertion surface of the stopper holder faces downward, there is no intrusion of rainwater, and the side walls on both sides of the stopper holder prevent damage to the stopper holder due to mischief by children. You can also aim for
Furthermore, when inserting the plug, the push-up lever is driven by pressing the push button, and the plug receiver is rotated so that the insertion surface faces upward against the biasing force of the return spring. After inserting the plug into the socket, the plug socket is biased by the return spring so that the insertion surface faces downward, so even if you forget to press down on the plug socket as in the conventional case, the plug socket will not open from the insertion surface. This has the effect that there is no infiltration of rainwater. In addition, by providing a push button to rotate the stopper holder, there is no need to hold the insertion surface of the stopper holder exposed by the side wall in order to rotate the stopper, thereby reducing the risk of electric shock. Especially when your hands are wet, you can hold the push button without holding the insertion surface of the plug holder, rotate the plug holder, and connect the plug without getting an electric shock. It is something.
