Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1-4, a plug-pull convenient socket comprises a plug 1 and a socket 2, wherein the plug 1 and the socket 2 are both square box bodies, a first spring 3 is welded on the inner wall of the plug 1, a stop block 4 is welded on the first spring 3, a circular groove 5 is arranged on the end surface of one side of the stop block 4 close to the socket 2, a through hole 16 is arranged on one side of the plug 1 close to the socket 2, the groove diameter of the circular groove 5 is larger than the aperture of the through hole 16, the plug 1 comprises two conducting strips 6, two spring leaves 7 are welded on the inner wall of one side of the socket 2 close to the plug 1, a guide rod 9 is connected with one side of the socket 2 close to the plug 1 in a sliding manner by penetrating through the side wall, the rod diameter of the guide rod 9 is smaller than the aperture of the through hole 16, two connecting strips 11 are welded on one end of the guide rod 9 far away, one end that socket 2 inner wall was kept away from to second spring 10 and the one end welding of keeping away from plug 1 of guide arm 9, be equipped with two hydraulic pressure casees 13 in the socket 2, first permanent magnet 17 has all been welded to the one end that every hydraulic pressure case 13 is close to second spring 10, all there is solenoid 14 in the winding on every first permanent magnet 17, second permanent magnet 15 has all been placed to the one end that has welded first permanent magnet 17 in every hydraulic pressure case 13, the outer wall that every hydraulic pressure case 13 welding has first permanent magnet 17 one end has all been welded current conducting plate 12, every current conducting plate 12 all is connected with solenoid 14 through the wire, the equal sealing sliding connection of one end that first permanent magnet 17 was kept away from to every hydraulic pressure case

The inner walls of the second permanent magnet 15 and the hydraulic tank 13 are in sealed sliding connection, one end, close to the first permanent magnet 17, of the second permanent magnet 15 is opposite to the magnetic pole of the first permanent magnet 17, and the attraction force of the first permanent magnet 17 to the second permanent magnet 15 is larger than the weight of the second permanent magnet 15; the direction of the magnetic field generated after the electromagnetic coil 14 is electrified is opposite to the direction of the magnetic field of the first permanent magnet 17, and the generated magnetic field is stronger than the magnetic field generated by the first permanent magnet; one end of the guide rod 9 close to the plug 1 is in a bolt shape, when the stop dog 4 is extruded carelessly, the guide rod 9 enters the circular groove 5, when the stop dog 4 is loosened, under the extrusion of the side wall of the circular groove 5, the guide rod 9 enters the socket 2 again due to the bolt shape of the guide rod 9, and the mistaken touch can be effectively prevented.

In the invention, in the process of inserting the plug 1 into the socket 2, the conducting strip 6 is contacted with the reed 7, the conducting strip 6 and a connected electrical appliance form a closed loop, so that current flows on the conducting strip 6, the stop block 4 cannot extrude the first spring 3 and move towards the side wall of the plug 1 under the action of no external force, the stop block 4 can block the through hole 16, so that the guide rod 9 can be abutted against the inside of the socket 2 in the process of inserting the plug 1 into the socket 2, the second spring 10 connected with one end of the guide rod 9 can be extruded in the process of moving the guide rod 9, finally the connecting sheet 11 on the guide rod 9 is abutted against the conducting plate 12, so that the electromagnetic coil 14 is electrified, the electromagnetic coil 14 can generate a magnetic field, and as the direction of the magnetic field generated by the electromagnetic coil 14 is opposite to the direction of the magnetic field of the first permanent magnet 17, and the magnetic field intensity of the electromagnetic coil 14 is stronger than that the magnetic field intensity formed by, make originally the second permanent magnet 15 that attracts mutually with first permanent magnet 17 begin to keep away from first permanent magnet 17 for the hydraulic oil in second permanent magnet 15 motion and the extrusion hydraulic tank 13, hydraulic oil will extrude piston 8, promote the direction slip of piston 8 to conducting strip 6, will extrude conducting strip 6 finally, make conducting strip 6 and reed 7 closely laminate, prevent effectively that conducting strip 6 and reed 7 from breaking away from easily, reach the locking purpose of plug.

When plug 1 is pulled out to needs, press dog 4 toward the inner wall of plug 1, when dog 4 is in the part in the plug 1 outside and the laminating in the plug 1 outside, the opening of the circular slot 5 of seting up on dog 4 will coincide with through-hole 16, at this moment, originally by keeping off guide arm 9 outside the plug and beginning to move toward circular slot 5 under the effort of second spring 10, when guide arm 9 offsets with circular slot 5 bottom, connecting piece 11 and current-conducting plate 12 disconnection, make solenoid 14 outage, at this moment, the magnetic field that solenoid 14 produced disappears, second permanent magnet 15 is under the appeal effect of first permanent magnet 17, begin to move toward first permanent magnet 17 direction, make the hydraulic oil backward flow of originally extruding piston 8, piston 8 no longer extrudes current-conducting plate 6, make pulling out that the plug can be easily, realize the effect of easily pulling out.

Although the terms of the plug 1, the socket 2, the first spring 3, the stopper 4, the circular groove 5, the conductive plate 6, the reed 7, the piston 8, the guide rod 9, the second spring 10, the connecting plate 11, the conductive plate 12, the hydraulic tank 13, the electromagnetic coil 14, the second permanent magnet 15, the through hole 16, the first permanent magnet 17, etc., are used more herein, the possibility of using other terms is not excluded.
