The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1,2,3 illustrate, the chamber door opening device of electronic safe of the present utility model, include control circuit board 12, dead bolt 3, dead bolt seat 1, latch bolt spring 2, cam 4, eccentric wheel 5; rocking arm 9; support of motor 6; microswitch 7; motor 10; mechanical lock 8; shift fork 11 critical pieces such as grade; wherein chamber door 13 is to be rotatably connected to casing 14; general this being rotationally connected adopted being articulated and connected that pivot pin relatively simple for structure cooperates with axle sleeve at large; can open automatically when dead bolt is locked in order to make chamber door 13; hinged place of chamber door 13 and casing 14 is provided with torsion spring, and torsion spring has omitted among the figure.Between casing and the chamber door door lock mechanism is installed, and have the control circuit board 12 and a numeric keypad of control gate latch mechanism action, its key is that chamber door 13 1 side positions are provided with the elastic lock tongue 3 that is supported by latch bolt spring 2, elastic lock tongue 3 is to use dead bolt seat 1 positioning and fixing on the inboard of chamber door 13, latch bolt spring 2 just is supported between dead bolt 3 and the dead bolt seat 1, and it makes dead bolt can make certain elastic telescopic.Accordingly, the opening inside line at casing 14 has lockhole, the insertion of confession dead bolt.Built-in chamber in this side of casing is set with support of motor 6 for 15 li, by support of motor 6 motor 10 and microswitch 7 are fixed together, they are cooperated and installation easily, and microswitch 7 is exactly to be used for controlling motor on the control circuit to change the switch that stops here.15 li base plates also are fixed with the rocking arm 9 that opens the door by pivot structure in the built-in chamber of this side of casing; rocking arm 9 is " L substantially " shape, pivot structure can make rocking arm make the rotation of certain angle; rocking arm 9 tops withstand on the dead bolt 3 and are mated; rocking arm 9 bottoms contact cooperation with the shift fork 11 of machine insurance lock; built-in chamber 15 sidewalls of this side of casing also are fixed with flexible member 17, and flexible member 17 1 ends are supported on rocking arm 9 tops, make rocking arm have certain elastic reset ability.And machine insurance lock 8 also is installed in 15 li in the built-in chamber of this side of casing, and machine insurance lock 8 adopts the crosses lock for good.Output shaft is installed simultaneously and has been connected with eccentric wheel 5 and cam 4 on the motor 10, and cam 4 cooperates with microswitch 7 on the control circuit, and eccentric wheel 5 cooperates with rocking arm 9 tops and contacts.Circuit board 12 is fixed on 15 tops, built-in chamber of this side of casing, is provided with numeric keypad 16 in tank surface simultaneously.

Its operating principle of chamber door opening device of this electronic safe is such, after the user imports correct enabling signal by button or other electronics input mode, control circuit output current control motor 10 on the circuit board 12 rotates counterclockwise, drive its cam 4 and depress microswitch 7 once, control circuit stops to motor 10 power supplies after detecting this signal, motor 10 can only rotate a circle and stop, therefore, after circling, cam 4 and eccentric wheel 5 still stop at the angle position before rotating, also driving eccentric wheel 5 when motor 10 rotates drives the rocking arm 9 that opens the door and turns an angle around the rotating shaft of C point, rocking arm 9 tops of opening the door just promote dead bolt 3 withdrawal, the lockhole that breaks away from casing is so chamber door is opened under the drive of other end hinge place torsion spring; Because eccentric wheel 5 still is in original angle position after rotating a week, opens the door rocking arm 9 under the effect of flexible member, is attached on the eccentric wheel 5, the user is after taking out goods, available hand closes upper chamber door, and dead bolt 3 stretches out under the promotion of latch bolt spring 2 to be locked in the casing lockhole, so chamber door has been locked; When the electronics opening device breaks down or reason such as forgets and can not normally unpack owing to password, can open by mechanical opening device, the user inserts key with cross safety lock 8, clockwise rotate an angle of 90 degrees degree, shift fork 11 inclined-planes of mechanical lock screw in the tail end of the rocking arm that opens the door and make it to raise, see Fig. 4,6, make the rocking arm 9 that opens the door rotate an angle, open chamber door around the rotating shaft of C point.
