Description
The utility model relates to a kind of lock, specifically is a kind of ciphering type magnetic card door lock with anti-theft feature.
Existing magnetic card door lock, although dead bolt and cylinder plate syndeton are varied, its theftproof performance is all not ideal enough; And existing general safe-guard door lock, yet exist easily prize, easily unload, problem such as key transreplication, anti-theft effect is not good enough.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of rational in infrastructure, the antitheft magnetic card door lock that theftproof performance is good.
The utility model is realized with following form:
The utility model mainly comprises inside and outside handle, handle, magnetic card lock body, lock body shell, magnetic card key, dead bolt, it is characterized in that, behind the handle ratchet is arranged outside, interior handle connects one and slides piece, ratchet, fork match with ratchet, fork is fixed on the pivot pin that slides piece, slides guide upright post is housed on the piece, and guide upright post connects slide carriage up and down.
The utility model slides the piece front end cylinder dead bolt is housed, and what link to each other with handle is a livelock tongue, and cylinder dead bolt and livelock tongue are installed in the lock body shell side simultaneously.
The utility model is owing to adopt the interlinked mechanism that slides piece and ratchet, handle opens the door direction when rotating greater than certain angle outside, drive the outwards motion rapidly of cylinder dead bolt, slide carriage moves up and down under the effect of guide upright post interlock up and down simultaneously, it is dead with door lock to promote upper and lower cotter joint, plays the effect of tamper-resistant function; If rotate greater than certain angle by the direction of closing the door, ratchet is blocked by ratchet, and fork breaks away from ratchet under the drive of sliding piece, just can't open without key outside.
Accompanying drawing 1 is the utility model front view.
Accompanying drawing 2 is the utility model drive mechanism schematic diagram.
Below in conjunction with accompanying drawing the utility model being done one elaborates.
As shown in Figure 1, 2, the utility model comprises outer handle (1), handle (2), internal end cover (3), interior handle (4), magnetic card lock body (7), magnetic card key (8), lock body shell (10), behind the handle (1) ratchet (14) is arranged outside, interior handle (4) connects one and slides piece (11), ratchet (12), fork (13) match with ratchet (14), fork (13) is fixed on the pivot pin that slides piece (11), slide guide upright post (6) is housed on the piece (11), slide carriage (9), following slide carriage (16) in guide upright post (6) connection.
The utility model slides piece (11) front end cylinder dead bolt (17) is housed, and what link to each other with handle (2) is a livelock tongue (15), and cylinder dead bolt (17) is installed in lock body shell (10) side simultaneously with livelock tongue (15).
Handle (4) is sliding piece (11) rear end in the utility model, and interior handle connects one cranks arm (5), and with square shaft with slide piece (11) and be connected.
Concrete using method of the utility model and principle are such.
Close to the doorstep, the livelock tongue slips into snap close automatically, and door is promptly closed.At this moment, when outer handle (1) is rotated angle greater than 20 degree by the direction of opening the door, slide the interlinked mechanism effect of piece (11) by ratchet (14), drive cylinder dead bolt (17) outwards motion rapidly, go up simultaneously slide carriage (9) and following slide carriage (16) under guide upright post (6) interlock effect, move up and down, it is dead with door lock to promote upper and lower cotter joint, plays the effect of tamper-resistant function; Otherwise, to shut behind the door, outer handle (1) rotates in the opposite direction, and livelock tongue (15) is promptly opened in fork (13) effect Xiamen, plays the effect of interim storm door.If rotate greater than after 20 angles of spending by the direction of closing the door, ratchet (14) is blocked by ratchet (12), and fork (13) disengaging ratchet (14) under the drive of sliding piece (11) just can't be opened without key outside simultaneously.Handle (4) in indoor turning directly acts on crank arm (5), drives to slide outwards motion of piece (11), and is under the interlock effect that door lock is dead.Otherwise piece (11) is slided in handle (4) withdrawal in rotating, and pulling handle (2) is opened door.
