Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear；It is complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, the present invention provides a kind of technical solution: the plug that one kind will not loosen, including plug body 1, on
Plug 2, connecting shaft 3, the first groove 4, deflecting roller 5, the second groove 6, lower plug 7, connecting spring 8, oblique hook 9, reset spring 10,
Button 11 and insulation sleeve 12, the upper surface center of plug body 1 offer the first groove 4, and setting on the inside of the upper end of the first groove 4
There is connecting shaft 3, rotational structure is constituted by connecting shaft 3 between plug body 1 and upper plug 2, and the shape of the first groove 4 is inserted with upper
First 2 shape matches, and upper plug 2 can be received to 4 the inside of the first groove, to realize turn of 3-phase plug and two-pin plug
It changing, the other end of connecting shaft 3 is connected with plug 2, and offers the second groove 6 inside the left and right sides of 2 lower section of upper plug,
The lower surface of plug body 1 is internally provided with connecting spring 8, and the left and right sides of connecting spring 8 is respectively connected with deflecting roller 5, turns to
Vertical centerline between wheel 5 about connecting spring 8 is symmetrical, and constitutes elastic construction between deflecting roller 5 and connecting spring 8, from
And the distance between achievees the purpose that two lower plugs 7 and can change, and then improve the problem of plug easily loosens；
The upper surface of deflecting roller 5 has been internally embedded lower plug 7, and the outer wall of lower plug 7 is provided with oblique hook 9, lower plug 7 with
Snap-in structure is constituted between deflecting roller 5, and is cooperated between deflecting roller 5 and the second groove 6 and constituted slide construction, and underthrust
First 7 be respectively provided with deflecting roller 5 there are two, the direction for rotating lower plug 7 can be facilitated, so that lower plug 7 be made to adapt to inserting for various kinds
Hole, and lower plug 7 can be freely rotated in deflecting roller 5, and deflecting roller 5 can slide in the second groove 6, thus lower plug 7
Direction is free to rotate, and reset spring 10 is connected between the lower end inside face of oblique hook 9 and the lower end outside face of lower plug 7, and
The lower end outer wall of oblique hook 9 is connected with button 11, and lower plug 7 constitutes elastic construction by reset spring 10 with oblique hook 9, and tiltedly hook 9
Shape be triangle, while tiltedly hook 9 matched with socket aperture, oblique hook 9 can be caught in jack, thus prevent plug pine
De-, the surface of plug body 1 is arranged in insulation sleeve 12, and the shape of insulation sleeve 12 is identical as the shape of plug body 1, and insulation sleeve 12
With a thickness of 1 millimeter, plug body 1 can be attracted with socket, so that leave no gaps, so as to prevent jack from intaking,
Cause danger.
Working principle: for this kind of plug that will not be loosened, being used cooperatively by connecting shaft 3 and upper plug 2 first,
The conversion that three plugs and two plugs can be realized to plug, is allowed to be not only suitable for Three-hole socket to be also applied for two hole socket, socket
In certain instances be mostly two holes, thus solves the problems, such as thus to bring use it is inconvenient, by deflecting roller 5 and lower plug 7 it
Between group connect, lower plug 7 can be made to be freely rotated in deflecting roller 5, so that lower plug 7 be made to adapt to the jack of various kinds, can be prevented
Cause lower plug 7 to fall off during pulling up plug 7, and pass through the connection of connecting spring 8 between two deflecting rollers 5, simultaneously
Deflecting roller 5 can slide in the second groove 6, thus achieve the purpose that the distance between two lower plugs 7 can change, Jin Ergai
Oblique hook 9 can be caught in jack by the problem of kind plug easily loosens by the cooperation between button 11 and reset spring 10, from
And the problem of preventing plug from easily loosening, while insulation sleeve 12 has actuation effect, can be attracted plug body 1 with socket,
So that leaving no gaps, so as to prevent jack from intaking, danger is caused.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
