Embodiment

As depicted in figs. 1 and 2, a kind of self-locking button, comprise lower house 1 and upper shell 2, upper shell 2 is positioned on the upper end of lower house 1, the inner chamber of upper shell 2 communicates with the inner chamber of lower house 1, namely the lower surface of upper shell 2 is provided with alignment pin 3, and lower house 1 upper end surface is provided with location hole, realizes location by alignment pin and location hole, pedestal 4 is provided with in the chamber of lower house 1, pedestal 4 is fixedly connected with the bottom surface of lower house 1, one side of pedestal 4 is provided with the first hang plate 5, the parallel beneath of the first hang plate 5 is provided with the second hang plate 6, one side of the first hang plate 5 and the second hang plate 6 is fixedly connected with pedestal 4, first hang plate 5 is fixedly connected with the two ends of riser 7 respectively with the opposite end of the second hang plate 6, and the first hang plate 5, second hang plate 6 and riser 7 form a tilting fore shaft that Open Side Down, slider block 8 is provided with in upper shell 2, slider block 8 is fixed in upper shell 2, vertical sliding rod hole is provided with in slider block 8, vertical slide bar 9 is provided with in sliding rod hole, the cross section of slide bar 9 is square, slide bar 9 axially can move up and down along it, the upper end of slide bar 9 is provided with return spring 10 and postive stop baffle 11 from bottom to up successively, return spring 10 is between postive stop baffle 11 and slider block 8, postive stop baffle 11 can apply axial pressure to spring, postive stop baffle 11 contacts connection with upper shell 2 upper surface and realizes spacing cooperation, the upper end of slide bar 9 passes and to be threaded with button cap 12 or bonding to upper shell 2 is outer, the lower end of slide bar 9 and the link of latch hook 13 are connect by spring leaf 14, the cross section of latch hook 13 is L-type, latch hook 13 keeps coaxial line by spring leaf 14 and slide bar 9, the hook portion of latch hook 13 is close to the first hang plate 5 and corresponding, can not interfere with pedestal 4 in the descending process of hook portion of latch hook 13.

As shown in Figure 3, the application of a kind of self-locking button in earphone, be equipped with positive pole contact 15 and negative pole contact 16 in lower house 1 and upper shell 2, the positive and negative electrode contact in lower house 1 is connected with player 17 by wire; Be connected with earphone 18 by wire in upper shell 2; After lower house and upper shell locking, the positive and negative electrode contact in lower house and upper shell forms loop; Self-locking button realizes connecting the switching between circuit and open-circuit line two states, and improves the stability of both connections.

The below of described second hang plate is provided with multiple hang plates of distribution downwards, and the opposite end of multiple hang plate is connected to form multiple fore shaft by riser.Advantage: multiple fore shaft realizes the locking of many gears, the coupling mechanism force namely between latch hook and fore shaft, becomes large from top to bottom gradually.Its structure is mapping, can implement completely according to text description those skilled in the art.

Operation principle: as shown in Figure 4, button cap promotes slide bar and slides axially along it, and the hook portion promoting latch hook contacts with the first hang plate; After contact, under the active force of slide bar, hinged latch hook produces beat along the incline direction of the first hang plate, and slide bar continues motion, after making the hook portion of latch hook cross the minimum point of the first hang plate, the hook portion of latch hook, in fore shaft, unclamps slide bar, and latch hook just returns by spring leaf, return spring band moving slide-bar return simultaneously, the slide bar of return applies axial pulling force to latch hook, thus makes the hook portion of latch hook apply tightening force to fore shaft, namely realizes the object of upper-lower casing locking; As shown in Figure 5, again promote slide bar, hinged latch hook produces beat along the incline direction of the second hang plate, and slide bar continues motion, after making the hook portion of latch hook cross the minimum point of the second hang plate, the hook portion of latch hook departs from fore shaft, unclamp slide bar, return spring band moving slide-bar return, the slide bar of return pulls latch hook to be repositioned to initial condition, latch hook just returns by spring leaf, namely realizes the object that upper-lower casing unlocks.
