Description

Three-safety numerically controlled remote control alarm puzzle lock for safe

The utility model relates to a kind of safety cabinet lock.

Present widely used safety cabinet, as the mechanical cipher safety cabinet, dialing handle and chuck axis fuse, and protrude in the cabinet door, and available instrument applies the violence damage chuck, and password loses insurance function.The tapered end lock core is destructible also, also can use violence on handle, opens the cabinet door thereby the inner transmission mechanism of safety cabinet is damaged.In recent years, a kind of single channel numerical control electronic password safe is arranged on the market, safety performance is strong than the mechanical cipher safety cabinet, but when breaking down, circuit is difficult to out cabinet, manufacturer's maintenance way is to import power supply from a place to electromagnetic valve, cause safety cabinet to be opened, in case reveal method of supplying power to, then this cabinet loses safety effect.Because these safety cabinets are easily by violence damage, the safety cabinet theft case is increasing, and national wealth sustains losses severely.

The purpose of this utility model is to avoid the defective of above-mentioned safety cabinet, provides a kind of violence to be difficult to destroy, the dependability height, and the two-way numerical control electronic password safe with onsite alarming and tele-alarm is locked.

Technology contents is: this lock has three safeties, i.e. electronic cipher insurance, the big lock insurance of pellet shot from a slingshot and the insurance of tooth plate mechanism.Adopt two-way numerical control electronic cipher, 20 password keys divide two assemblings to join, and are used by switch control two-way, and one the tunnel is electronic password lock, and another road is the electronic cipher safety lock, under the timer effect, finishes the program of unblanking by the fixed time and can open cabinet; The other tooth plate mechanism of handle lock divides goes up tooth plate and lower tooth plate, and the safety plug restriction tooth plate in the tooth plate groove moves, and upper and lower tooth plate and tooth plate frame withstand the cabinet keeper plate; Lock core destroys or pulls out, and tooth plate plays safety effect.Warning system is divided onsite alarming and tele-alarm, warning device and electronic password lock, timer, electromagnetic valve parallel connection.

The utility model is compared with existing safety cabinet, has the following advantages: 1. reliability height, and when one road electronic password lock breaks down, can start another road electronic cipher safety lock and open cabinet, use, easy to maintenance.2. 20 password keys divide two assemblings to join, and the password capacity is big.3. handle lock cooperates insurance with tooth plate, strengthens safety performance.4. protect and test no any projection on the cabinet door, inconvenience applies violent lock breaking, and specious, and moulding can be adopted furniture or household electrical appliance style.5. unlock operation time, program, digital entanglement and vibrations, then onsite alarming or tele-alarm, under same transformer, remote control distance is the 2-3 kilometer.Open the microwave remote control simultaneously, around safety cabinet, in 35 square metres, do not contact safety cabinet and also can report to the police.

Embodiment:

Do following explanation in conjunction with the accompanying drawings, the big lock of pellet shot from a slingshot (1) dead bolt (3) lower end has screw (30) that drive link (31) is fixed on the dead bolt among Fig. 1; Big lock bumper bar (26) right-hand member is enclosed within the bumper bar cover (28), and dead bolt (3) when stretching out stops it that bumper bar block set (29) is fixed on the cabinet door.Big lock bumper bar (26) left end, fixing by the bumper bar bearing (25) on the bolt plate (15).Numerical control electronic cipher system (27) is connected with drive link (31) by A, B, C by wire rope (32).

Electromagnetic valve support (4) is fixed on the cabinet door by screw (5), and electromagnetic valve (6) is installed in the support (4), is communicated with the electron number control circuit.Solenoid shaft (7) is enclosed within the axle sleeve (8), can upper and lowerly move.Electromagnetic valve bumper bar (10) right-hand member is enclosed within the bearing (9), and left end is fixed on the bolt plate (15).Bolt panel seat (12) is supported on the cabinet door by screw rod (11), and the tightening latch on the bolt plate (13) inserts in the keeper hole (14).

(16)-(24) are handle lock and tooth plate mechanism arrangement among Fig. 1, and internal construction is seen Fig. 2.Lock core (23) is outer lock core cover (24) and steady pin (33), and tooth plate frame (20) lower end is fixed on the bolt plate (15), and the upper end has screw (34) that last tooth plate (18), the lower tooth plate (21) of tooth plate frame and its underpart is hinged.There is teeth groove in last tooth plate (18) left side, is fixed in tooth plate safety plug (19) insertion on the cabinet door in the tooth plate teeth groove.Spring (16) by spring steady pin (17) location is pressed in the tooth plate left side.Lower tooth plate (21) right side has pointed tooth, and tooth plate tentacle (22) rotation that is arranged in lock core cover (24) time can be stirred pointed tooth, promotes to move on the lower tooth plate.

Two-way numerical control electronic cipher system basic composition is seen Fig. 3.Be communicated with power supply after timer, electronic password lock, electronic cipher safety lock, electromagnet (valve), the remote control alarming unit parallel connection among the figure.Electronic password lock, electronic cipher safety lock are made up of 5 figure place sign indicating numbers, and coded lock is the normal lock that uses, and cipher lock plays the security insurance effect.20 password keys divide two assemblings to fit on the cabinet door, with the cabinet door be same plane, two-way numerical control electronic cipher is used by switch control.Remote control alarming unit divides main frame and extension set, and main frame dress janitor's room is in the extension set dress safety cabinet.A transformation depressor, remote control distance 2-3 kilometer.Also has microwave alarm in the cabinet.

Use and method of operating: key is inserted big lock pin (2) rotation, dead bolt (3) enters in the big lock (1), for moving to right, big lock bumper bar (26) prepares, dead bolt (3) drives transmission bracket (31) motion, affect transmission mechanism (A, B, C) by wire rope (32), open electron number control circuit wicket.Program password according to establishment is in advance pressed the corresponding digital key, and electromagnetic valve (6) is connected power supply, produces magnetic, and solenoid shaft (7) is sucked in the axle sleeve (8), and electromagnetic valve bumper bar this moment (10) is opened path.Key is inserted in the handle lock core (23), the clockwise direction rotation, tooth plate tentacle (22) promotes lower tooth plate and moves to right, promote simultaneously to go up on the tooth plate (18) to move, tooth plate frame (20) is gone up tooth plate/(18) and is moved to right with lower tooth plate with bolt plate (15), make the tooth of tooth plate cross the mobile tooth pitch of safety plug (19) from.After tentacle (22) breaks away from teeth groove, spring (16) will be gone up tooth plate and depress, and safety plug (19) blocks.After lock core revolves and turns around, repeat an action.Tentacle (22) promotes tooth plate and moves step by step, and the tooth plate frame drives bolt plate (15) and progressively moves to right, and is last, and tightening latch (13) breaks away from keeper hole (14), and safe door is opened.

Close safety cabinet, elder generation's counter rotation handle lock core (23), promote tooth plate and tooth plate frame and bolt plate (15) and move to left, lock bumper bar (26) and electromagnetic valve bumper bar/(10) greatly and reset thereupon, be big lock dead bolt (3) and overhanging the preparing of solenoid shaft (7).Eliminate the electronic cipher signal, solenoid shaft is stretched out automatically.Rotate big lock core, dead bolt (3) is overhanging, and A, B, C transmission mechanism reset, and safety cabinet cuts out, and is in the security insurance state.
