Detailed Description

As shown in fig. 1, a waterproof gasket 2 is added between a circular socket hole device 1 and a waterproof box 3, and then the waterproof gasket is fixed below the circular socket hole device 1 by using a fixing device 4 to be locked, so that the effect of preventing water from entering the waterproof box is achieved. The external stereoscopic effect is shown in fig. 9 and 10.

As can be seen from fig. 2, the inner neutral conductive metal contact 6 and the inner live conductive metal contact 10 of the circular outlet means 1 are connected to the outer neutral conductive metal contact 7 and the outer live conductive metal contact 11, respectively, and the outer metal contacts are sealed integrally with the circular outlet means 1 so that water does not flow therethrough into the waterproof box. When water enters the circular socket hole device 1, the socket can be turned over, so that the water flows out along the inner inclined planes of the right socket hole 5 and the left socket hole 9, and the water is prevented from remaining in the socket.

As shown in fig. 3, in the power-on state of the present invention, the electrical plug 14 is inserted into the circular socket hole device 1 and rotated to the power-on position, at this time, the external zero line conductive metal contact 7 coincides with the power zero line 8 in the waterproof box 3, and the external live line conductive metal contact 11 coincides with the power live line 13 in the waterproof box 3, so as to achieve the power-on effect. Effect principle the top view can be seen in fig. 4.

As can be seen from fig. 5, in the power-off state of the present invention, the external zero line conductive metal contact 7 is staggered from the power zero line 8 in the waterproof box 3, and the external live line conductive metal contact 11 is staggered from the power live line 13 in the waterproof box 3, so that when not in use, the two metal contacts inside the circular socket hole device 1 will not be connected to the power live line 13 and the power zero line 8, and even if the circular socket hole device 1 is filled with water or inserted with a metal foreign object, the electric shock and short circuit will not occur. The principle of the breaking effect is shown in the top view in fig. 6.

As can be seen from fig. 7 and 8, when the socket is not in use, the homing device spring 15 will automatically push the circular socket hole device 1 back to the power-off state against the homing device insertion hole 12. The stereoscopic effect is shown in fig. 9 and fig. 10.

As can be seen from fig. 9 and 10, when the circular socket hole device 1 is rotated to the power-on state, the limit lock 17 is inserted into the side groove 16 of the circular socket hole device 1 in a downward sliding manner, so as to prevent the socket from automatically rotating to the power-off position when in use. When power is required to be cut off, the limit lock 17 is lifted upwards, and the power can be automatically reset and cut off.

As can be seen from fig. 11 and 12, the limit lock 17 is pushed downward by the limit lock spring 18, and is automatically pushed and locked when the circular socket hole device is rotated to the power-on position.

As can be seen from fig. 13 and 14, the circular rotary locking device 19 and the rubber protective sleeve 20 in the plug protection device are combined into a sealed whole, after the rubber protective sleeve 20 is sleeved into the plug, the tail end of the rubber protective sleeve 20 is wrapped by the fixing ring buckle 21 and fastened by screws, so that the waterproof effect is achieved, and the side-view effect after the rubber protective sleeve is additionally installed is shown in fig. 15. The positioning point 22 is used for being embedded into the side groove 16 in fig. 9, so that when the handle 24 is used for rotating the circular rotary locking device 19, the circular socket hole device 1 can be driven to synchronously rotate, and the limiting lock 17 is automatically pushed into the limiting groove 23 to be locked after the circular socket hole device is in the power-on position, so that the automatic reset power-off is prevented. The rotary fixing inclined surface 25 and the rotary fixing inclined surface 26 of the groove outer ring can enable the circular rotary locking device 19 to be tightly attached to the waterproof box 3 when rotating.

As can be seen from fig. 15, the side of the position limiting lock 17 is a slope, and when the plug protector is pushed in and rotated, the position limiting lock 17 is forced upward.

As can be seen from fig. 16, when the circular socket hole device 1 is reset, water can flow out from the water outlet 27.
