Description

Safe with electric handcuff

The utility model belongs to the robber-captured type safety cabinet.

It catches the flashboard of stealing device employing band arch breach existing robber-captured type safety cabinet, catch robber's device and adopt mechanical interlinked mechanism control, this safety cabinet does not have adaptive capacity because the arch breach of flashboard is fixed to the size of burglar's hand, and the reaction speed of mechanical interlinked mechanism and reaction sensitivity are all relatively poor, thereby catch robber's poor performance, sometimes even not catch robber's ability, bigger because of advancing hand door-plate opening again, thereby the cabinet door is not too firm, its open method is the same substantially in addition, is easy to divulge a secret.

The purpose of this utility model is to provide a kind of employing ratchet to copy finger, and controlled the electronic hand robber-captured type safety cabinet of copying of ratchet motion by Circuits System at the existing common defects of stealing safety cabinet of catching.

The purpose of this utility model realizes by following technological approaches: a kind of electronic hand safety cabinet of copying, comprise cabinet and cabinet door, cabinet and cabinet door flexibly connect, the bolt assembly of switchboard door and the combination lock and the cylinder lock of control bolt assembly have been installed on the cabinet door, offered one on the cabinet door simultaneously and opened aperture, its main points of catching robber's device and control device thereof are as follows:

1, cabinet door inboard is provided with the ratchet assembly that a front end has movable ratchet below opening aperture, between ratchet assembly rear end and the ratchet assembly installing plate extension spring has been installed;

2, the ratchet assembly is provided with a pin-and-hole, cabinet door inboard is provided with a slider pin that matches with set pin-and-hole on the ratchet assembly, the slider pin rear side is provided with the power assembly that a control slider pin retreats, and the slider pin leading portion is provided with a spring that slider pin is resetted;

3, bolt assembly rear end is provided with a dormant bolt, and cabinet door inboard can be touched the position and is provided with a button opening below the aperture finger, is connected by connecting rod between button and the dormant bolt, is provided with a normal switch power supply switch by the motion control of connecting rod by connecting rod;

4, combination lock, other its corresponding normally closed switch K1, the K2 of being provided with respectively of cylinder lock, normally closed switch K1, K2 are parallel with one another, the other secondary power supply switch that is provided with by its motion state control of ratchet assembly, this secondary power supply switch has a constant close contact K3, paralleling switch and constant close contact K3 that normally closed switch K1, K2 constitute, the motor of normal switch power supply switch, power supply and power assembly constitutes an electric series loop.

Like this, after correctly combination lock and cylinder lock being opened, normally closed switch K1, K2 all are disconnected, thereby control circuit is in open-circuit condition, and power assembly is not worked, as long as this stretch into finger opens aperture and press button, the cabinet door can be opened after opening dormant bolt.

If as long as combination lock and cylinder lock have any one among the two correct the unlatching not, so, just have at least a switch to be in closure state among normally closed switch K1, the K2, at this moment, if being stretched into the unlatching aperture, finger presses button, normal switch power supply switch promptly is closed, power assembly work, the release slider pin, the ratchet assembly is pressed to finger rapidly under the effect of extension spring, its ratchet is promptly pinned finger firmly, and the constant close contact K3 of secondary power supply switch disconnects simultaneously, power assembly quits work, and the burglar is promptly firmly caught.

The utility model is owing to adopt as above technical measures, thereby reaction speed is fast, and ratchet does not change with the thickness of finger to the pressing force of finger, when finger is stuck, more earn card tighter, to steal performance good so catch, the while is simple in structure, low cost of manufacture.

Following accompanying drawing provides an embodiment of the present utility model:

Fig. 2 catches robber's device to copy hand and ways of relief schematic diagram

Fig. 3 is the controlling organization electrical schematic diagram

The embodiment that provides below in conjunction with accompanying drawing further describes the utility model:

The electronic hand safety cabinet of copying, comprise cabinet and cabinet door, cabinet and cabinet door are flexibly connected by ball, the bolt assembly ［ 12 ］ of switchboard door and the combination lock ［ 12 ］ and the cylinder lock ［ 9 ］ of control bolt assembly ［ 11 ］ have been installed on the cabinet door, the other normally closed switch K1 that is subjected to this lock control that is separately installed with of combination lock ［ 12 ］ and cylinder lock ［ 9 ］, K2, normally closed switch K1, K2 is parallel with one another, offer one on the cabinet door simultaneously and open aperture ［ 1 ］, bolt assembly ［ 11 ］ rear end is provided with a dormant bolt ［ 10 ］, cabinet door inboard can be touched the position at unlatching aperture ［ 1 ］ below finger and be provided with a button ［ 2 ］, be connected by connecting rod between button ［ 2 ］ and the dormant bolt ［ 10 ］, be provided with a normal switch power supply switch ［ 3 ］ on the connecting rod next door, a back-moving spring also has been installed on connecting rod simultaneously by the motion control of connecting rod.

It is caught and steals device is to be installed on the inboard ratchet assembly ［ 4 ］ of opening aperture ［ 1 ］ below of cabinet door, ratchet assembly ［ 4 ］ front end has movable ratchet ［ 14 ］, between ratchet assembly ［ 4 ］ rear end and the ratchet assembly installing plate extension spring ［ 15 ］ has been installed, ratchet assembly ［ 4 ］ is provided with a pin-and-hole, cabinet door inboard is provided with a slider pin ［ 7 ］ that matches with the last set pin-and-hole of ratchet assembly ［ 4 ］, slider pin ［ 7 ］ rear side is provided with the power assembly ［ 6 ］ that a control slider pin ［ 7 ］ retreats, and slider pin ［ 7 ］ leading portion is provided with a spring that slider pin ［ 7 ］ is resetted.
