Description

Safety box

(1) technical field

The present invention relates to the improvement of all kinds of safety boxs in market inventions.

(2) background technique

In the prior art, well known safety box is provided only with door lock and coded lock insurance in the market, these a little casees of insurance Cabinet is easy to be opened security door using tool for destroying or skill wood tricks of the trade by law-breaker；Or it is aligned using strong acid class chemical medicinal liquid Security door is opened after the weak another part of key pitting corrosion lock core；Or violent means are used, the meanss of destruction opening such as saw, prize, pounding, boring Security door.Although nearest market is born, a kind of inside door uses the advanced guarantor with two security doors of mechanical interlocking function control Dangerous case.But the technical pattern is complicated, cost is high, and client is difficult to receive.

(3) summary of the invention

In view of the existing technical defect, the present invention is intended to provide a kind of have by gear-box gear cooperation inside door door-hinge Machine control interlocking safety case (cabinet) inside door of translocation is controlled, raising prevents from equally reaching inside door unlatching after destroying, enhancing insurance Safety coefficient reduces user's loss.

The present invention is completed by following scheme, a kind of safety box, including cabinet, gear-box, displacement rack gear, displacement control Piston processed, shaft gear；Several gears are set in upper interlayer gear-box before the cabinet, in gear-box rear class gear shaft square hole Suit second shifts door-hinge upper end square shaft behind the door, and the mobile tooth in displacement door-hinge lower section shaft gear engagement displacement rack gear rear end, which plays, to be stretched Exhibition is acted on withdrawal；The displacement rack gear middle section unlatching control pin hole and shift control piston center hole and control seat stepped hole Vertical movements inserting control pin door bolt plays unlatching and locks positioning action.

The second door-hinge gear pushes displacement rack gear to play the role of stretching, extension and withdrawal by first of door-hinge control.

Discount is loaded respectively multiple to the first sect and the second sect using snak link on the two sides shift control piston Bit switch effect.

The control pin door bolt designs the above stairstepping of two-stage.

The present invention solves existing disclosed safety box and only sets traditional type insurance method, and safety coefficient is lower and novel cost The technological deficiency of valuableness etc..The technology is equipped with and automatically resets mechanical joint control safety device, substantially increase function advance and Destructive technical know-how and reduction cost, popularize social security safety precaution.
