Referring to fig. 2 and 5, when the locking portion 612 cooperates with the locking groove 513 to lock the pulling-assisting member 61 and the control member 51, the pulling-assisting spring 62 is in a compressed state, at this time, when the user presses the pressing portion 512 until the control member 51 is located at a position closest to the second through hole 14, the locking portion 612 is disengaged from the locking groove 513, the pulling-assisting member 61 and the control member 51 are unlocked, the pulling-assisting member 61 is driven by the pulling-assisting spring 62 to slide in a direction away from the first through hole 13 until the mating portion 613 abuts against the limiting portion 16, at this time, the pulling-assisting spring 62 is in a normal state and is not pressed or stretched, and the inserting rod 2 is still inserted into the through hole 6111.
When the pulling-assisting piece 61 and the control piece 51 are in an unlocking state, the pulling-assisting piece 61 surrounds the part, close to the plug body 1, of the plug rod 2, the anti-falling piece 4 is effectively prevented from being directly exposed, and meanwhile external impurities can be reduced to fall into the mounting groove 21, so that the influence on normal use of the plug is reduced.
In this embodiment, for facilitating the assembly of the plug, it is preferable that the plug body 1 is integrally formed by assembling two halves, the plug body 1 is formed by assembling a plurality of parts, the specific assembling mode of the plug body 1 is not described in detail in this embodiment, and the whole of the plug body 1 after assembling is shown for clarity in the drawings.
The implementation principle of the plug for the power strip provided by the embodiment of the application is as follows:
in the process of plugging the plug and the socket 7, the two pressing parts 512 are pressed down while the plug body 1 is gripped by the gripping convex rings 15, the control part 511 drives the anti-falling part 4 to rotate so as to retract the resistance increasing part 41 into the mounting groove 21, then the plug rod 2 is aligned to the jack 71 on the socket 7 and is inserted, the abutting part 611 abuts against the socket 7 so as to drive the auxiliary pulling part 61 to slide towards the direction close to the first through hole 13 against the elastic force of the auxiliary pulling spring 62 until the abutting part 611 abuts against the plug body 1, at the moment, the clamping part 612 is inserted into the clamping groove 513, then the pressing part 512 is released, the control part 51 is reset under the driving of the reset spring 52, self-locking is formed between the control part 51 and the auxiliary pulling part 61, at the moment, the anti-falling part 4 rotates so as to extend the resistance increasing part 41 to abut against the hole wall of the jack 71, and the plug and the socket 7 are plugged completely;
when the plug is pulled out from the socket 7, only one hand is required to press down the two pressing parts 512 simultaneously, so that the making part drives the anti-falling part 4 to rotate to retract the resistance increasing part 41 back into the mounting groove 21, at the moment, the clamping part is separated from the clamping groove 513, the pulling assisting part 61 and the control part 51 are unlocked, the pulling assisting part 61 slides and pops up in a direction away from the first through hole 13 under the driving of the pulling assisting spring 62, and the pulling assisting part 61 and the socket 7 are propped against each other, so that the plug body 1 pops up in a direction away from the socket 7 under the interaction of force, and then the pressing part 512 is released.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
