Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses an explosion-proof waterproof socket, as shown in fig. 1-7, including socket body 1, its characterized in that: the socket body 1 is hinged with a safety cover 2, and a gap 3 is formed between the safety cover 2 and the socket body 1; a cavity 4 is formed in the socket body 1, an interlocking rod 5 is arranged in the cavity 4, two ends of the interlocking rod 5 penetrate through the socket body 1 to extend out, a spring 6 is further arranged in the cavity 4, and two ends of the spring 6 are abutted against the inner wall of the cavity 4 and the interlocking rod 5; the socket body 1 is also provided with a rocker switch 7, and the rocker switch 7 is also fixedly provided with a mandril 8; the safety cover 2 is provided with a locking groove 9, a limiting groove 10 and a switch baffle 11, the limiting groove 10 is matched with the interlocking rod 5, and the interlocking rod 5 is matched with the limiting groove 10 to limit the rotation of the safety cover, so that the position accuracy of the safety cover 2 is ensured; switch baffle 11 cooperatees with rocker switch 7, and switch baffle 11 is used for sheltering from rocker switch 7 for when switch baffle 11 is unmovable, operating personnel can't control rocker switch 7.

Further, the socket body 1 is provided with a plug 12 which is used in a matched manner, the plug 12 is provided with a sealing tube 13, the sealing tube 13 is matched with the gap 3, and the sealing tube 13 is used for ensuring that the plug 12 has good explosion-proof and waterproof performances after being connected with the socket body 1; the sealing pipe 13 is provided with a locking pin 14, the locking pin 14 is matched with the locking groove 9, and the locking pin 14 and the locking groove 9 are used for ensuring the connection firmness.

Further, the cavity 4 and the interlocking rod 5 are arranged in an L shape.

Further, ejector pin 8 length is less than the distance between 11 inner walls of switch baffle to socket ontology 1, the distance that the seesaw distance of rocker switch 7 plus ejector pin 8's length is greater than the distance between 11 inner walls of switch baffle to socket ontology 1 for guarantee that ejector pin 8 can not block the rotation of safety guard 2 when rocker switch 7 is in the off-state, and when rocker switch 7 is in the on-state, can block the rotation of safety guard 2.

Further, the plug 12 is provided with a plug core 15, the socket body 1 is provided with a jack 16, and the plug core 15 and the jack 16 are arranged correspondingly; a conductive contact 17 is arranged in the jack 16, and the conductive contact 17 is used for fully contacting with the inserting core 15 to complete circuit conduction; the conductive contact 17 is electrically connected to the rocker switch 7, so that when the rocker switch 17 is in an on state, the conductive contact 17 is powered, and when the rocker switch 17 is in an off state, the conductive contact 17 is not powered.

The working principle is as follows: when the plug 12 is connected with the socket, if the socket is powered on, the ejector rod 8 on the rocker switch 7 is ejected, the safety cover 2 is dislocated and rotated, the relative positions of the locking groove 9 and the inserting hole 16 are deviated, when the locking pin 14 is matched with the locking groove 9, the inserting hole 16 and the inserting core 15 cannot be matched, when the inserting hole 16 is matched with the inserting core 15, the locking pin 14 cannot be matched with the locking groove 9, and the plug 12 cannot be inserted into the socket body 1. If the socket is in a normal power-off state, the locking pin 14 can be aligned with the locking groove 9, the inserting core 15 is aligned with the inserting hole 16 to be inserted, and after the inserting action is completed, the interlocking rod 5 is pressed down by the plug 12, so that the interlocking rod 5 is moved out of the limiting groove 10; at this time, the safety cover 2 can be rotated to lock the locking groove 9 and the locking pin 14, the switch baffle plate 11 is driven to rotate along with the rotation of the safety cover 2, the blocked rocker switch 7 is leaked out, and an operator can press the upper part of the rocker switch 7 to start the power supply of the socket, as shown in fig. 7; at this point, the connection of the plug 12 with the socket body 1 is completed.

When separating plug 12 and socket ontology 1, if the socket is not cut off the power supply, ejector pin 8 can restrict the rotation of safety guard 2, locking groove 9 and locking pin 14 between can't remove the locking, plug 12 can't extract socket ontology 1, need press rocker switch 7 lower part this moment, normally cut off the power supply with the socket, rocker switch 7 presses the lower part after, ejector pin 8 moves to the inboard, no longer restrict the rotation of safety guard 2, can rotate safety guard 2 smoothly, remove the locking between locking pin 14 and locking groove 9, as shown in fig. 6, extract plug 12 from socket ontology 1, accomplish the separation of plug 12 and socket ontology 1. Finally, the spring 6 resets the interlocking lever 5, and the interlocking lever 5 is engaged with the stopper groove 10 to restrict the rotation of the safety cover 2 to prepare for the next connection.
