The specific embodiment
Specific embodiment 1:
Fig. 1, Fig. 2, Fig. 3, Fig. 4 a, Fig. 4 b, Fig. 5 a, Fig. 5 b, Fig. 6 a, Fig. 6 b and Fig. 6 c constitute specific embodiments of the invention 1.
Referring to Fig. 1 to Fig. 4 b, present embodiment comprises lock body 1, lock core 2, two dead bolts 3, matched key 4, lock core cover 5, movable key holder 6, driving mechanism, transmission mechanism.Lock core cover 5 for " ∏ " shape structure, it is fixed on the centre position of an end of the medial surface of lock body 1, flexible lock core 2 is positioned at lock core cover 5, is provided with elasticity locking bolt 15 between lock core cover 5 and the lock core 2; Lock core overlaps 5 opposite sides and is provided with two guide strips 7 side by side, forms groove between the two boards, and movable key holder 6 is stuck in the groove just, and can move along groove; Transmission mechanism is arranged on a side of guide strip 7, and by tooth bar 10, gear 11 is formed, and an end of tooth bar 10 connects key holder 6, the tooth engagement on gear 11 and the tooth bar 10.Driving mechanism is formed by driving core 12 and the core retainer plate 13 supporting with it, the front end that drives core 12 exposes outside the lock body 1, the end that drives core 12 is connected with the input of transmission mechanism, and the front end that drives core 12 can be a handgrip, thereby rotates by rotating handgrip rotating drive core 12 driven gears 11.The shell of lock body 1 also is provided with a handle 14, and handle 14 is connected with the far-end of the round bar 31 of two dead bolts 3 by a connector.The user can open lockset from Men Neila handle 14, and is easy to use.
Referring to Fig. 2, two offsides of lock core cover 5 are respectively equipped with support member 9; One end of movable key holder 6 is fixed with a push pedal 61.Two dead bolts 3 are separately positioned on the both sides of two guide strips 7, dead bolt 3 is made up of a round bar 31 and an oblique tongue 32, the near-end of round bar 31 is arranged in the support member 9, far-end is with tiltedly tongue 32 is affixed, the far-end of round bar 31 be axially arranged with a pole 33, the round bar 31 between support member 9 and the pole 33 is provided with a back-moving spring 34.Push pedal 61 on the key holder can promote dead bolt and move to the lock core direction.
With reference to Fig. 3, Fig. 4 a, Fig. 4 b, Fig. 5 a, Fig. 5 b, described lock core 2 is provided with concaveconvex structure, and promptly raised line 2a can play the selection effect to matched key.Matched key 4 is made up of separable key head 41, the shank of the key 42.Have two detent 41a on two pairs of sides of key bit 41; Corresponding two detents of the shank of the key are provided with two clamping pin 42a, form the clamping to key bit 41.Key 62 is also established concaveconvex structure, has the selection function to key.Key holder 6 is provided with key 62 and loads key, and the corresponding key bit 41 in two sides has two direction recess 63.When key holder 6 moved, the key bit 41 of described matched key 4, the shank of the key 42 separated, and key bit 41 moves with key holder, and 42 of the shank of the keys are fixed in the direction recess 63 of key holder 6 two sides.
The operating principle of present embodiment is as follows:
With reference to Fig. 6 a, Fig. 6 b and Fig. 6 c, elder generation's rotating drive core 12 front ends (handgrip), these handgrip driven gear 11 rotations, because gear 11 meshes with the tooth of tooth bar 10, therefore gear 11 drives tooth bar 10 motions again, and tooth bar 10 drags key holder 6 again and moves then, and swing handle makes key holder 6 move to lock core 2 directions again, this moment, two dead bolts 3 bounced back to lock core 2 ends, but did not also retract to the position that can unblank.In the time of need unblanking, key 4 is inserted keyhole, because the key 62 on the key holder 6 is aimed at keyhole 8, therefore key bit 41 can enter in the key 62 by keyhole 8, when being rotated further handgrip, the key bit 41 of key 4 separates with the shank of the key 42 thereupon, and key bit 41 moves to lock core 2 with key holder 6, and 42 of the shank of the keys are fixed in the direction recess 63 of key holder 6 two sides.Key bit 41 on key holder 6 enters lock core cover 5 and these elasticity locking bolt 15 displacements of elasticity bolt 15 contact rear drives, lock core 2 can be overlapped in 5 at lock core to rotate, be that elasticity locking bolts 15 in the lock core 2 are when opening, key holder 6 just drives dead bolt 3 to be continued to open fully up to dead bolt 3 to lock core 2 directions retractions (moving).When need taking out key 4, only need the counter-rotation handle, up to key bit 41 and the shank of the key 42 again in conjunction with after, just key 4 can be taken out.If do not insert matched key 4, make matched key head 41 enter key 62, even swing handle drives key holder 6 and moves to lock core 2 positions, lock core 2 can not rotate, and dead bolt 3 can not opened fully, and promptly lockset can not be opened.
Present embodiment is applicable to door lock, is particularly useful for building door lock.
Specific embodiment 2:
With reference to Fig. 7, the characteristics of present embodiment are: described transmission mechanism is made up of long tooth bar 10a, short tooth bar 10b, the first gear 11a and the second gear 11b, tooth engagement on the first gear 11a and the long tooth bar 10a, long tooth bar 10a, short tooth bar 10b are separately fixed at the both sides on movable key holder 6 tops; When lock core when key operated, the tooth on the short tooth bar 10b can mesh with the second gear 11b; The wheel shaft of the first gear 11a is connected with the clutch end of described driving mechanism, and the wheel shaft of the second gear 11b is fixed in the lock body; The second gear 11b face is provided with three pins; Gear 11b is connected with three dead bolts by pin, and dead bolt 3 is made up of round bar 31a and circle tongue 32b.The shell of lock body 1 is not established handle.Other are identical with specific embodiment 1.
The operating principle of present embodiment is as follows:
In the time of need unblanking, elder generation's swing handle, handle drives first gear 11a rotation, the first gear 11a meshes with the tooth of long tooth bar 10a, drive long tooth bar 10a motion again, long then tooth bar 10a drags key holder again and short tooth bar 10b moves together, make the key on the key holder aim at keyhole, thereby key can be gone in key by keyhole.Then, swing handle makes key holder move to the lock core direction again.At this moment, the key bit of key separates with the shank of the key, and key bit moves to lock core with key holder, and the shank of the key then is fixed in the direction recess of key holder two sides.When the key bit on the key holder is opened with making lock core after lock core contacts, be that locking bolt in the lock core is when opening, the key toilet can drive lock core to be continued to move, at this moment, tooth on the short tooth bar 10b on the key holder and second gear lock 11b engagement, drive the second gear 11b and rotate, the second gear 11b drives dead bolt and vertically moves, and opens fully up to dead bolt.When need taking out key, only need the counter-rotation handle, up to key bit and the shank of the key again in conjunction with after, just key can be taken out.If do not insert key, swing handle, the driving key holder will stop to move when moving to the lock core position, and at this moment, the tooth on the short tooth bar 10b and the second gear lock 11b be not engagement also, and lock can not be opened.
Present embodiment is applicable to the safety cabinet lock.
Specific embodiment 3:
The characteristics of present embodiment are: described dead bolt 3 is made of " U " type ring, constitutes padlock type lockset.In the present embodiment, an end of " U " type ring is connected with the output of transmission mechanism.All the other structures are with specific embodiment 1.
