The specific embodiment

Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in accompanying drawing 1 to 13, the utility model comprises lock panel 1, lock housing 2, cover plate 15 and main hyoplastron 8; It is characterized in that: be fixed with three master lock tongues 5 by main tongue riveted joint groove 8-5 on described main hyoplastron 8 one sides, on these main hyoplastron 8 opposite sides, cover has latch bolt spring 16 respectively; The two ends up and down of this main hyoplastron 8 are respectively equipped with hook tongue centrepin 8-3, on this hook tongue centrepin 8-3, are connected with respectively the tongue 3 of rising to the bait, lower hook tongue 4, and this tongue 3 of rising to the bait, lower hook tongue 4 are active in respectively in the dead bolt hook 15-1 on cover plate 15; The described tongue 3 of rising to the bait, lower hook tongue 4 are connected with upper universe rod 9, lower universe rod 10 respectively, and on this, universe rod 9, lower universe rod 10 are active in the universe rod groove 2-2 on lock housing 2, and stretch out in the groove 2-3 at lock housing two ends Shang Xia 2; Described lock panel 1 is screwed the side in lock housing 2, and three master lock tongues 5, the tongue 3 of rising to the bait, lower hook tongues 4 intert and are active in this lock panel 1 respectively; Described cover plate 15 is covered on lock housing 2 by screw.Also comprise locking key 11, shift fork 12, stop button 13 and safety block 14, described locking key 11 is provided with lock hook 11-1, and this lock hook 11-1 is by the 2-1 phase hook of locking on reduction torsion spring 17 and lock housing 2; Described shift fork 12 is provided with retaining point 12-1, unblank a 12-2 and square rod hole 12-3, and this retaining point 12-1 contacts with the retaining jacking block 8-1 on main hyoplastron 8, and a 12-2 that unblanks contacts with the unlatching jacking block 8-2 on main hyoplastron 8.

Described stop button 13 acts on safety block 14, and an end cover of safety block 14 has back-moving spring 17, and this back-moving spring 17 is contacted with on the lock housing wall; This safety block 14 is provided with locks a 14-1 and the anti-some 14-2 that ejects, and this locks a 14-1 and the anti-some 14-2 that ejects acts on the insurance jacking block 8-4 on main hyoplastron 8.These safeties act as: stop button 13 is generally in open mode, and at this moment safeties cut little ice to whole lock body, when rotation stop button 13, drives safety block 14 and rotates under the elastic force effect of back-moving spring 18, and two kinds of situations are arranged:

One,, when lock body during in opening, the anti-some 14-2 that ejects has hooked insurance jacking block 8-4, and it can't be completed from being opened to the state of locking; Applying on electronic lock is exactly the channel function that lock body can't eject.

Two, when lock body is in the lock state, lock a 14-1 and withstood insurance jacking block 8-4, it can't be completed from locking onto the state of unlatching; Apply on electronic lock is exactly the interior safeties that can't open the door in outside.

The described master lock tongues 5 that are positioned in the middle of main hyoplastron 8 are provided with main tongue directing shoulder 5-1, and this main tongue is locked on the 5 spacing main hyoplastron track 15-2 that are active in cover plate 15; Upper locking key 7 is positioned at main tongue directing shoulder 5-1, and roller 6 is connected in the end of locking of upper locking key 7, is provided with top with this upper locking key 7 of end opposite of locking end and hits a 7-1, and this top is hit a 7-1 and acted on locking key 11, its on this end in locking key 7 cover back-moving spring 18 is arranged.Acting as of roller 6: one, regardless of opening direction inside and outside the left and right of door, unlike that latch bolt of conventional lock body, distinguish inside and outside left and right; Two, adopt wheeled design effectively to reduce friction, make part more wear-resisting, long service life.

From the opening to the lock-out state (as shown in Figure 1):

Roller 6 under external force, in drive, locking key 7, make top hit a 7-1 and clash into the rear rotation of locking key 11, lock hook 11-1 breaks away from a 2-1 that locks, locking key 7 under the elastic force effect of latch bolt spring 16, main hyoplastron 8 is under the track of main hyoplastron track 15-2, outwards eject, drive master lock tongue 5 simultaneously, roller 6, upper locking key 7 is ejected, upper universe rod 9, lower universe rod 10 is protruding, the tongue 3 of rising to the bait, lower hook tongue 4 is outwards routed up under the track of dead bolt hook 15-1, so far lock body remains on lock-out state, retaining point 12-1 has withstood retaining jacking block 8-1 and has made master lock tongue 5, main hyoplastron 8 can not be retracted in lock body under external force, play tamper-resistant function.

From locking state to opening (as shown in Figure 2):

Rotation square rod hole 12-3, a 12-2 promotion unlatching jacking block 8-2 makes to unblank, make main hyoplastron 8 under the track of main hyoplastron track 15-2, inwardly retract, while master lock tongue 5, roller 6, upper locking key 7 is retracted, upper universe rod 9, lower universe rod 10 is inwardly retracted, the tongue 3 of rising to the bait, lower hook tongue 4 under the track of dead bolt hook 15-1, inwardly turn over into, after arriving to a certain degree, locking key 11, under the twisting force of reduction torsion spring 17, hooks a 2-1 that locks, and makes master lock tongue 5, main hyoplastron 8 can not stretch out outward under the elastic force effect of latch bolt spring 16, from then on completes opening.

The utility model is not limited to above-mentioned embodiment; no matter do any variation on its shape or material formation; every employing structure design provided by the utility model, be all a kind of distortion of the present utility model, all should think within the utility model protection domain.
