Description

Mechanical anti-theft lock

The utility model relates to a kind of mechanical anti-theft lock, is specially adapted to safety cabinet, secret chamber, national treasury, armoured van use, belongs to High Security Level door lock technical field.

Existing theftproof lock mostly is the unit core greatly, and single the check mark realized the effect of maintaining secrecy with its check mark function, because the structure of these locks is single, level of confidentiality is low, thus the time have by the stolen disaster of sled and take place, people thirst for having the hot insurance theftproof lock of structure to occur for this reason.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of two-shipper core is provided, the two check marks of double dial, double lock tongue, and size of key has surpassed the B level, reaches 1 * 10 ¹²The mechanical anti-theft lock of level.

The purpose of this utility model is achieved in that it is made of lock body, movement, dead bolt dial, and its structural feature is: movement is arranged before and after being made of major and minor movement group, has shifting block on the every movement respectively, transfers the sign indicating number cam.Dial arranges that the EXT scale dish is installed in to stir on the screw rod and matches with the accent sign indicating number cam of main frame core group before and after being made of dial in outer, and middle dial is sleeved on to stir on the screw rod and matches with the pillbox sign indicating number cam of secondary movement group.Two dead bolts are set to 90 degrees and are positioned at lock body, and dead bolt is connected with lock hook.

The purpose of this utility model can also reach by following technical measures: between two groups of movements dividing plate is arranged, every group by three movements formations.Scale on place, the middle dial is 100 equal portions, and the scale of the scale of middle dial and EXT scale dish is perpendicular.

The utlity model has following advantage compared to existing technology:

1, insurance level of confidentiality height.The required standard that meets the PGA/73-94 of the Ministry of Public Security fully, size of key have surpassed B level 6 * 10 ⁷, reached 1 * 10 ¹²Level.

2, scientific structure design is reasonable.Adopt double dial, two check marks, lock number can be set to numerous.

3, adopt the two-shipper core, shifting block is all arranged on the every movement, dialing is provided with freely.

4, adopt double lock tongue, two dead bolts become 90 ° to be arranged in the lock body, up and down the lock of control gate cabinet point.

5, easy for operation, be convenient to suitability for industrialized production.

The explanation of accompanying drawing drawing:

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Among the figure, (4) are colluded in lock body (1), movement (2), lock hook (3), insurance, lock bolt (5), transfer sign indicating number cam (6), dead bolt (7), EXT scale dish (8), middle dial (9), location dial (10), door cabinet (11), screw rod (12), central dividing plate (13), retainer spring (14), steel ball (15), lock hook return spring (16), lock bolt lock hook connecting bolt (17), jump ring (18), ring (19), machine core board (20), degree of tightness piece (21), gear (22), fluted disc (23), breach (24), shifting block (25), positioning bolt (24).

Lock body of the present utility model (1) is square aluminum casting.Two dead bolts (7) are installed in the lock body (1), two dead bolts (7) are set to 90 degrees, be installed in respectively on the lock bolt (5), lock bolt (5) is made up of positioning ball (15), retainer spring (14) and is fixedly mounted in the lock body (1), the middle part of two lock bolts (5) is separately installed with lock hook (3), and the lock hook (3) that is provided with return spring (16) is fixedlyed connected with bolt (17) with lock bolt (5).Transfer the sign indicating number cam to be set to two, be positioned at lock body (1).Transfer sign indicating number cam (6) to be installed in the lock body (1) with movement (2) is coaxial.Movement of the present utility model (2) is made of major and minor movement group, arrange before and after the major-minor movement group, movement (2) is made up of machine core board (20), degree of tightness piece (21), gear (22), fluted disc (23), every group of movement is 3, be equipped with shifting block (25) on the every movement, shifting block (25) is positioned on the gear (22).It is to prevent strap that the effect of ring (19), ring (19) is arranged in the movement groove.In order to reach goal of the invention, also be provided with jump ring (18) on the movement (2), breach (24).There is dividing plate (13) centre of major-minor movement group, before and after dividing plate (13) is divided into the major-minor movement.Dial of the present utility model is set to two, EXT scale dish (8) is the master calibration dish, middle dial (9) is secondary dial, EXT scale dish (3) is installed in to be stirred screw rod (12) and goes up and to match with the accent sign indicating number cam (6) of main frame core group, and middle dial (9) is sleeved on to be stirred the back that is positioned at EXT scale dish (9) on the bolt (12) and EXT scale dish and be set to 90 degrees accent sign indicating number cam (6) interoperation with secondary movement group.EXT scale dish (3) constitutes the double dial up dish with middle dial (9).Number on the middle dial (9) has half latent root of Dahurian angelica on location dial (10), and location dial (10) is installed in door cashier's office in a shop.Be close to a cabinet (11), location dial (10) is gone up jagged, and its breach is the sign of checking the number.EXT scale dish (8), middle dial (9) high scale are 100 equal portions, as figure (5).Scale and the scale on the EXT scale dish (8) on the middle dial (9) are perpendicular.

The method of manipulating of the present utility model: each dial is set three numbers, be set at (85,26,38) as middle dial, EXT scale dish (8) is set at (38,75,80), operation according to the following steps: 1, left-handed middle dial (9), and counterclockwise to first group of number 85, the number of setting 85 is rotated four circles, and last 85 aim at the sign that opens on the location dial (10).2, dial (9) and clockwise direction stop when opening sign when aiming at for the third time second group of number 26 in the middle of the dextrorotation.3, left-handed middle dial (9) stops and fastening positioning bolt (26) when aligning opens sign for the second time the 3rd group of number 38, dial in the middle of fixing.4, order and the number of times of adjusting by middle dial (9) adjusted the password (38,75,80) that EXT scale dish (8) is set, when be transferred to last group digital 80 aim at for the second time in the middle of dials (9) stop when right open sign.5, unclamp positioning bolt (26), dial is in lock bolt (5) draws in lock body (1) in the middle of right rotation, and lock is just opened.Its course of work is: two cams (7) drive two lock hooks (3), pass to two dead bolts (6) that are mutually 90 ° by two bolt shaft that lock hook (3) is installed, the flexible keying that realizes door lock of dead bolt (6).Rotation master calibration dish just EXT scale dish (8) drive screw rod (12) rotates, and cam (7) rotation that screw rod (12) drives main frame heart group realizes the master check mark.The notched sleeve pipe of middle dial (9) by matching with EXT scale dish (8).(sleeve pipe matches with the cam (7) of secondary movement group) drives secondary movement group cam (7), realizes the check mark of secondary movement group, and dead bolt (6) opened and closed after the major-minor movement was aimed at password.By the order of unblanking number aligning number of changing is indicated during the tone mark sign indicating number, key is inserted half-twist in cam (7) hole, make the fluted disc (23) of cam top movement chip, fluted disc can rotate arbitrarily, with the reverse 90 ° of recoveries of key, fluted disc this moment (23) will be fixed on the movement (2) and not rotate behind the check mark.
