The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.

Embodiment one

As depicted in figs. 1 and 2, the electronic lock of embodiment one of the present utility model, the electronic lock circuit plate that comprises lock housing 1, is installed on the lock housing 1 (is positioned at lock housing 1, not shown) and the mechanical lock that is used for opening electronic lock (be positioned at lock housing 1, also not shown among the figure), the structure of electronic lock circuit plate and mechanical lock is same as the prior art, does not repeat them here.Lock housing 1 is provided with the over cap 5 for the lockhole 61 that covers mechanical lock, is provided with between lock housing 1 and the over cap 5 at over cap 5 to open and the microswitch 4 that is triggered when exposing lockhole 61, and microswitch 4 is electrically connected with microprocessor on the electronic lock circuit plate.In embodiment one, over cap 5 is slidingly connected on the lock housing 1.As depicted in figs. 1 and 2; the left and right sides of lock housing 1 is respectively equipped with chute 2; microswitch 4 is positioned on any side that lock housing 1 is provided with chute 2; and stretch out this side; as shown in Figure 3; the inboard of over cap 5 is provided with the slide rail 51 suitable with chute 2; the inboard of over cap 5 is provided with the projection 52 that the microswitch 4 that will stretch out described lock housing 1 when over cap 5 covers lockhole 61 is depressed; projection 52 position and microswitch 4 corresponding settings are when over cap 5 covers lock housing 1 surface, when covering lockhole 61; microswitch 4 is depressed by projection 52; when sliding protective cover 5 exposed lockhole 61, microswitch 4 was just upspring, thereby is triggered.As shown in Figure 4; when microswitch 4 is triggered to microprocessor 8 one triggering signals; microprocessor 8 confirms that just over cap 5 is opened, and the beginning timing, and an alert program prestores in microprocessor 8; when over cap 5 is opened beyond certain hour; such as 5s, 8s, microprocessor 8 just send alarm signal to buzzer 9 or alarm lamp 10; the related personnel just can in time dispose, and plays anti-theft effect.Buzzer 9 can adopt electronic lock self with buzzer 9, also can establish in addition the larger loudspeaker of volume, can also use together in conjunction with alarm lamp 10.If adopt legal mechanical key to insert lockhole 61, lock core is unblanked by operating machine, the used time is shorter, generally in 5s, just can open, if when adopting the attempt of illegal utensil to pry open mechanical lock, the general required time of expending is longer, and microprocessor just sends alarm signal, start light or audible alarm, the safety that has improved electronic lock.

As depicted in figs. 1 and 2, as preferably, also be provided with in the chute 2 for the inboard against over cap 5 and make its stable spring leaf 3.When over cap 5 covered on the lock housing 1, spring leaf 3 was resisted against on the slide rail 51 of the inboard of over cap 5 or over cap 5 inboards, when opening or closing over cap 5, increased the stability of over cap 5, and it can not be free to slide.

Embodiment two

As shown in Figure 5, embodiment two is with the difference of embodiment one, and spring leaf 3 is arranged on the face that lock housing 1 is provided with lockhole 61, can play the effect of stablizing over cap 5 equally.

In above-described embodiment one and embodiment two, microswitch 4 all is positioned on the one side that lock housing 1 is provided with chute 2, in fact; microswitch 4 can also be arranged on the face that lock housing 1 is provided with lockhole 61; at this moment, its purpose all can be realized in the position and microswitch 4 corresponding settings of the projection 52 in the over cap 5.

In addition, in the above-described embodiments, over cap 5 is that the mode of taking to be slidingly connected cooperates with lock housing 1; in fact; over cap 5 can also be rotationally connected with lock housing 1, and for example: one side being rotatably connected on the lock housing of over cap, the another side of over cap is connected by buckle with lock housing.The inboard of over cap is provided with the projection that the microswitch that will stretch out lock housing when over cap covers lockhole is depressed.The position relative set of microswitch and projection, when covering lockhole with the assurance over cap, projection is depressed microswitch.

Certainly; the above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
