Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1, a kind of plug, as shown in figure 1, including pedestal 1 made of ambroin, pedestal 1 passes through upper and lower two
Shell hot melt molding.
Pedestal 1 is provided with two lock pins 2, and lock pin 2 is used to insert socket.
Lock pin 2 can be retracted to inside pedestal 1 by accent.
After lock pin 2 enters 1 inside of pedestal, accent can be blocked.
As shown in Fig. 2 the side of pedestal 1 hot melt has framework 56；
Framework 56 to be rectangular-shaped, framework about 56 two inwalls offer the slideway 54 of indent, the upper and lower side of shrouding 53 is equal
It is to slide on slideway 54, shrouding 53 realizes the closure to accent along the directional-sliding of slideway 54.
Shrouding 53 simultaneously offers the breach 55 of depression outwardly, and breach 55 is rectangular-shaped, and breach 55 is easy to employee's finger to apply
Power, so as to reach the light purpose for stirring shrouding 53.Two breach 55 are placed on contour sliding straight line, and such purpose exists
In employee can stir shrouding 53 with forefinger using thumb simultaneously and be opened and closed.
As shown in figure 3, offering sliding chamber 12 inside pedestal 1, sliding chamber 12 is used to accommodate the lock pin 2 after retraction.
The side wall of lock pin 2 is bonded setting with the guide wall 121 of sliding chamber 12, and the left and right side of two lock pins 2 is directed to wall 121
Limitation, therefore lock pin 2 is difficult to double swerve occurs in moving process, lock pin 2 can move according to set stability-of-path.
Hot melt is fixed with insulating bar 51 between two lock pins 2, and insulating bar 51 can be made of plastics, and insulating bar 51 causes two
Individual lock pin 2 can realize synchronous sliding.
Spring element 52 is placed in sliding chamber 12, spring element 52 is the first spring；One end of first spring is contradicted in sliding chamber 12
In cavity wall, the other end is set on the inserting column of insulating bar 51；First spring is in compressive state, therefore the first spring generation one is held
Long thrust, the thrust cause two lock pins 2 it is lasting maintain the movement tendency for skidding off pedestal 1.
As shown in Figure 3 and Figure 4, and lock pin 2 skids off and retraction slide chamber 12 station by engaging component engaged.
Opening up the first bayonet socket 21 and the second bayonet socket 22, the first bayonet socket 21 and the second card are offered on one lock pin 2
Length direction of the mouth 22 along lock pin 2 is arranged.
Sliding chamber 12, which connects, is fixed with rotating shaft 34, and swing arm 31 is arranged rotating shaft 34, and swing arm 31 can be with around the shaft 34 rotations；
One end of swing arm 31 contradicts flexible part 33, the other end of swing arm 31 the first bayonet socket 21 of direction；Elastic component 33 be in
The second spring of compressive state, the lower end of second spring are contradicted on the wall of pedestal 1, therefore the elastic force of second spring driving swing arm 31
It is screwed into the first bayonet socket 21.
And the outer wall of pedestal 1 offers perforation 41, chamber 12 is slided in the connection of perforation 41, and button 4 is equipped with perforation 41.
The lower end of button 4 is contradicted in the upper end of swing arm 31, is pressed downward button 4 so that swing arm 31 is towards compression second spring side
To rotation, swing arm 31 screws out the first bayonet socket 21, and now lock pin 2 is not affected by barrier constraint in the sliding direction of chamber 12 movement.
The part holt melt that button 4 is placed in sliding chamber 12 has block 42, and the barrier of block 42, should in the lower end of perforation 41
The purpose of design, reduce the phenomenon generation that button 4 freely detaches pedestal 1.
Therefore by pressing button 4, the sealed and unblock relation of the first bayonet socket 21 and swing arm 31 can be controlled.
Guide card 11 is fixed with inside sliding chamber 12, guide card 11 connects electric wire.
As shown in figure 5, guide card 11 is the copper sheet of evagination, guide card 11 is flexible, and the crowning of guide card 11 is contradicted in lock pin 2
Side, when lock pin 2 is in slipping, lock pin 2 remains contact condition with guide card 11.
The fixture block 32 of kelly group 3 plays effective snap action.
Swing arm 31 is caught in end and is fixed with fixture block 32, and fixture block 32 is set with the bending of swing arm 31, and fixture block 32 is towards the first bayonet socket 21；
Fixture block is caught in and skidded off the first bayonet socket 21 or the second bayonet socket 22, controls the fixed position when retraction and stretching of lock pin.
As shown in figs. 5 and 6, the second bayonet socket 22 is placed near the end of lock pin 2 outwardly.
When lock pin 2 is after retracting to sliding 12 inside of chamber, the rotation of fixture block 32 is caught in the second bayonet socket 22 so that lock pin 2 fixes
The position in chamber 12 is slided in retraction.
Operation principle：When lock pin 2 needs and socket plugs together, staff presses button 4, and lock pin 2 pushes away the first spring
Under power effect, lock pin 2 skids off pedestal 1；Staff's release button 4 in the slipping of lock pin 2, fixture block 32 block with the first bayonet socket 21
It is mutually clamped after closing alignment so that lock pin 2 is fixed on the station for stretching out sliding chamber 12.
When plug when not in use, lock pin 2 separates with socket, staff press button 4, then artificial promotion lock pin 2 to
Moved in sliding chamber 12, staff's release button 4 in the moving process of lock pin 2, phase after fixture block 32 is aligned with the engaging of the second bayonet socket 22
Mutually engaging so that lock pin 2 is fixed on the station that chamber 12 is slided in retraction, and now lock pin 2 is surrounded by the outer wall of pedestal 1, when pedestal 1 is stepped on
When stepping on, lock pin 2 is not susceptible to bend.
Embodiment 2, a kind of audio amplifier, as shown in fig. 7, comprises casing 6, casing 6 is provided with upper and lower two horn mouths, on casing 6
It is connected with power line 61, the plug being connected with power line 61 in embodiment 1.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
