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.

(5) specific embodiment
Attached drawing discloses the technology of the present invention structure, and embodiment is described in further detail in Structure Figure again below: including case
Body (1), gear-box (2), displacement rack gear (5), shift control piston (6), shaft gear (7);Upper interlayer before the cabinet (1)
Interior setting gear-box (2), gear-box (2) is interior to be arranged several gears, plays mutual transmission effect, gear-box (2) rear class gear
Axis square hole is set on the downside of central axis, suit second door (4) inside backward shift door-hinge (8) upper end square shaft, shift gate in axis square hole
Shaft gear (7) are arranged in axis (8) lower section, and shaft gear (7) engagement displacement rack gear (5) rear end is mobile tooth (12), make in the second sect (4)
Side rear axle gear (7) controls rotation by the first sect (3) axis and displacement rack gear (5) rear end mobile tooth (12) is pushed to play stretching, extension and receive
Effect is returned, shifts and two sides stroke hole location (13) is set on the ennation of rack gear (5) other side, two sides stroke hole location (13) is mounted on the
Balance stretching, extension is played behind two sects on two brackets (9) and withdraws migration, two bracket (9) intermediate parallel line setting controls
Displacement rack gear (5) two sides stroke hole location (13) is then sleeved on two bracket (9) screws and is fixed with nut, controlled by seat (10)
Inserting control pin door bolt (11) in seat (10) stepped hole processed and unlatching control pin hole (15) and shift control piston (6) hole;Described
Unlatching control pin hole (15) two sides connection is extended two sides stroke long hole less than normal, and two sides stroke long hole outer ledge is installed fixed
Position pin (14), positioning pin (14) are inserted into shift control piston (6) center stroke long hole, play two sides shift control piston (6)
Positioning action, unlatching control pin hole (15) both sides of the edge are using the steel plate for being bent into " 7 " shape and weld positioning guardrail (17), play
Two sides shift control piston (6) activity division positions and moves irregularly effect;The two sides shift control piston (6) is respectively
Two sides (two panels) design, two sides shift control piston (6) are inserted into unlatching control pin hole (15) above and use two sides snak link
Play the role of the first sect (3) and the second sect respectively free reset switch on discount (16);The displacement rack gear (5)
Middle section unlatching controls pin hole (15) and above shift control piston (6) two sides centre bore and control seat (10) center stepped bore is hung down
Straight activity orientation, control seat (10) center stepped bore for insert control pin door bolt (11) lower section it is trapezoidal, purpose be to play control
The up and down unlatching of cotter door bolt (11) with lock and positioning action, control pin door bolt (11) lower end connects vertical tooth rack, vertical tooth rack
Lower section tooth hingedly engages the second sect hand handle inboard gear and rotarily opens and lock;Open door procedure first opens the first sect (3)
Intermediate gear is rotated by gear-box (2) interior first gear out and is driven backward shift door on the inside of the second sect of rear class gear synchronous rotation
Hole location and control seat (10) upper shoulder hole position on hole location and shift control piston (6) in axis (8) door-hinge adjustment displacement rack gear (5)
Vertically, the second sect handle rotation is opened.
