Description

A kind of anti-demountor tool key cipher lock
Technical field the utility model relates to the lock that security door uses, and especially is used in public door with locking esidential building inside door lock.
Background technology is present, and esidential building and other civilian construction have used anti-theft safety door basically, and country has also issued corresponding standard GB 17565-1998.But the door in public door such as residential building, resident institute and the esidential building is not paid attention to accordingly, a lot of this type of door locks not, or with key operated lock, or the electronic lock with functions such as dialogue, videos.For public door, door is lock not, the salesman, pastes small advertisement, that collect scrap even the people for preparing to carry out unlawful activities directly near the anti-theft safety door of esidential building, even more serious is, the door of residential building, resident institute because there is not lock, becomes the favourable place that unauthorized person is hidden temporarily; Use the door of key operated lock, because the resident is many, the discrepancy personnel are many, open and close, lock a door etc. inconveniently especially, and in case in time do not lock, lock is easily lost or be stolen; Use the door of electronic lock, because electronic lock price height, the resident can bear high expense.For the door in the esidential building, if do not lock, the people of unlawful activities enters any Room, just can act arbitrarily at whole dwelling house; Use with key operated lock, bring more inconvenience to the resident undoubtedly.
Mechanical key cipher lock, easy to use, easy to operate, the mechanical key cipher lock of having authorized is a lot, but does not have all to consider that being applied to public Men Shisuo is illegally dismantled problem.This use is novel to prevent illegal dismounting when consideration is easy to use, simple to operate.
Summary of the invention is given full play to safety effect in order to make public door and esidential building inside door, and the utility model provides a kind of mechanical anti-theft lock, and this lock prevents dismounting, easy to use, cheap.
The technical scheme that its technical problem that solves the utility model adopts is: adopt 10 buttons, open lock by the mode by wherein cryptographic key, make and open lock, door is convenient; Adopt lock bolt sleeve, dead bolt is automatically reset, make when closing door and lock door lock is lived, make and lock a door conveniently; Adopt guard shield, the installation nut is enclosed in the lock, dismantle guard shield, could dismantle lock, increase safety by mode by cryptographic key.
The beneficial effects of the utility model are, public door of open and close and dwelling house inside door easily, password dismounting lock, be difficult for losing, safe, cheap, give full play to the safety effect of public door and dwelling house inside door, make the door of person non grata, prevent the wantonly activity of juridical-person at premises away from oneself.

Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Fig. 4 is that embodiment is installed in when last C-C sectional view among Fig. 1.
Fig. 5 is Fig. 2, Fig. 3 middle slide plate (11) structure chart.
Fig. 6 is Fig. 2, guard shield among Fig. 3 (14) structure chart.
1. mainboards among the figure, 2. in plate, 3.20 springs, 4.14 springs, 5. snap link; 6. support, 7. button, 8. code pins, 9. button slideway, 10.10 springs; 11. slide plate, 12. spring shafts, 13. tailstocks, 14. guard shields; 15. the handle slideway, 16. bolts, 17. handles, 18. lock bolt sleeves; 19. dead bolt, 20. screws, 21. passwords are buckled, 22.7 springs; 23. erection bolt, 24. panels, 25., 26. install nut.
Specific embodiment Fig. 1 is the front view of the utility model embodiment.Fig. 2 is the A-A sectional drawing of Fig. 1.In Fig. 2, mainboard (1) is bound up by 6 supports (6) with middle plate (2), and snap link (5) is fixed between mainboard (1) and the middle plate (2), and they form the skeleton of present embodiment.
Dead bolt (19), lock bolt sleeve (18) are bound up on the spring shaft (12) by screw (20), spring shaft (12) passes snap link (5) and penetrates two side openings of slide plate (11), between lock bolt sleeve (18) and snap link (5), lock bolt sleeve (18) and slide plate (11), spring shaft (12) and slide plate (11), be separately installed with 20 springs (3), 14 springs (4) and (10) three compressions of 10 springs spring, they form this
The executing agency of embodiment.
Support (6) provides slideway for simultaneously slide plate (11), and slide plate (11) can horizontally slip according to this; Spring shaft (12) can be that slideway horizontally slips with two holes of slide plate (11); All the time between mainboard (1) and middle plate (2), the slip of dead bolt (19) that driven by spring shaft (12) or the lock bolt sleeve drive is in lock bolt sleeve in the slip of the lock bolt sleeve (18) that is driven by spring shaft (12).
Fig. 3 is the B-B sectional view of Fig. 1.Button (7) is not when being pressed, and code pins (8) locking slide plate (11) makes it and can not horizontally slip; After button (7) was pressed, code pins (8) moved down simultaneously, and this moment, slide plate can horizontally slip.The structure chart of slide plate is seen Fig. 5; After slide plate (11) resetted, under 7 springs (22) effect, password was buckled on (21) and is moved, and promotion code pins (8), button move on (7), and slide plate is in the lock state, and can not horizontally slip.
When door is in closure state, lock when being in the lock state, dead bolt (19) is subjected to 14 springs (4) effect and stretches out and enter the dead bolt box, and lock bolt sleeve (18) can not stretch out because of the dead bolt box stops.After pressing password key (7), code pins (8) moves down, and slide plate (11) is subjected to 10 springs (10) and slippage to the right drives spring shaft (12), dead bolt (19) slippage to the right simultaneously, and lock is in out state, and can open the door this moment.
After door was opened, lock bolt sleeve was subjected to 20 springs (3) effects and left slippage is stretched out, and drove dead bolt (19), spring shaft (12) and the left reduction of spondylolisthesis of slide plate (11) simultaneously.
Door is in closing course, and dead bolt (19), lock bolt sleeve (18) are pressed into mainboard, and after the door closure, dead bolt (19) is subjected to 14 springs (4) effects and stretches out and enter the dead bolt box, and door, lock are in the lock state once more.
By above-mentioned button, three the steps the most basic of opening the door, close the door, realize the unlatching and the locking of door, simple, convenient.
During from the door drawback lock, hand push lock handle (17) moves to left, moving left and promote bolt (16) in the hole of handle (17) on handle slideway (15) moves left, bolt (16) promotes spring shaft (12) and moves left, spring shaft (12) drives dead bolt (19), lock bolt sleeve (18) moves to left, lock is opened, 10 springs (10) compression simultaneously, door is opened defensive position and is left handle (17), this moment, dead bolt (19), lock bolt sleeve (18), spring shaft (12) and bolt (16), handle (17) resetted under the effect of 10 springs (10).
Fig. 4 is that embodiment is installed in when last C-C sectional view among Fig. 1.By half knob erection bolt (23) with nut (26) is installed, will lock firmly with panel (24) and mainboard (1) and be fixed on the door.Owing to adopt half knob erection bolt (23), can't use instrument dismounting locks such as spanner, pliers, screwdriver outdoors; Can tool using install, the installation nut (26) of dismounting is by mainboard (1), tailstock (13) and guard shield (14) sealing; When press password key (7) is installed after, promote password by code pins (8) and buckle (21) and move down, guard shield this moment (14) can manually skid off, and makes nut (26) to be installed by the deblocking exposing surface, be in can install, disassembly status.Fig. 6 is Fig. 2, guard shield among Fig. 3 (14) structure chart.
By installation nut (26) deblocking is exposed, be convenient to dismounting, prevent illegal dismounting.
