Abstract
The utility model relates to a lock for automatically adding safety factor for a handle. Most of the existing ordinary safety locks need to rotate a key to lock a lock tongue to add the safety factor for a lock, but the operation is inconvenient. A lock tongue of the utility model is connected with a handle through a connecting rod, and meanwhile, the utility model is provided with an unlocking sliding block which can be shifted by a lock core shifting sheet and a locking sliding block which can lock the lock tongue; the two sliding blocks are connected with each other by a linkage rod; the utility model is also provided with an elastic lever of which the fulcrum is positioned at the centre; one end of the lever is connected with the lock tongue, and the other end is connected with the sliding block. When the door is locked, the locking sliding block can be driven to lock the lock tongue by rotating the handle by people to add the safety factor for a lock. The utility model has the advantage of convenient operation.
Description
The utility model belongs to a kind of safety lock.
Existing general insurance lock majority is to pin dead bolt with key to add insurance, and it is not too convenient to operate.
The utility model aims to provide a kind of lock that needs turning handle to add insurance with regard to energy automatic locking dead bolt.
The technical scheme that realizes above-mentioned purpose is (figure in conjunction with the embodiments): the utility model comprises lock housing 1, dead bolt 13, lock core body 2, lock core 3, can be with the plectrum 4 of lock core rotation, can drive the flexible handle 16 of dead bolt, it is characterized in that: the utility model is provided with two slide blocks that can slide along trapped orbit separately, one is to slide into certain position can enter the locking slide block 12 that the recessed step in dead bolt rear portion that stretches out lock housing pins dead bolt, one is the unlatching slide block 5 that can be stirred by plectrum 4, gangbar 10 two ends link to each other with the unlatching slide block with the locking slide block respectively, the utility model also is provided with the elastic force lever 14 of a fixed support 11 in the centre, elastic force lever one end is connected with dead bolt, and an end is connected with unlatching slide block or locking slide block.
Operating principle of the present utility model is: turning handle 16, dead bolt 13 stretches out outside lock housing, the end that elastic force lever 14 links to each other with dead bolt is outwards motion thereupon, the other end that links to each other with slide block has promptly been put aside certain elastic force energy, if this end links to each other with locking slide block 12, then this elastic force promptly directly acts on the locking slide block, if this end links to each other with unlatching slide block 5, then open slide block and can elastic force be acted on the locking slide block by gangbar 10, when dead bolt stretches out lock housing fully, when locking slide block 12 was aimed at the recessed step in dead bolt rear portions, the elastic force of the slide block that promptly is locked savings pushed recessed position, blocks dead bolt and can not withdraw.When unblanking, with key turns plectrum 4, promptly stir and open slide block 5, open slide block and drive 12 motions of locking slide block, and also movement therewith of elastic force lever one end that links to each other with slide block, and put aside certain elastic force to dead bolt by the other end that links to each other with dead bolt by gangbar, when locking slide block movement to disengaging dead bolt step, dead bolt is promptly withdrawn in lock housing under the elastic force effect,, rotates a lower handle again dead bolt is withdrawn fully so that dead bolt is withdrawn as the elastic force deficiency.
This safety lock is simple in structure, only needs the turning handle can the automatic locking dead bolt without key, and is easy to use.

The embodiment explanation
Present embodiment dead bolt rear portion is provided with the pin 7 of projection, in the sliding tray of embedding and handle 16 relatively-stationary connecting rods 15, the slide rail 9 of locking slide block 12 is vertical with the dead bolt direction of motion, moves to certain position to the dead bolt direction and can block the recessed step in dead bolt rear portion that stretches out lock housing it can not be withdrawn when locking slide block.
The slide rail 8 of opening slide block and the slide rail 9 of locking slide block are opened slide block and are positioned at the position that the plectrum 4 that can be fixed in the lock core rear portion is stirred in vertical direction.The locking slide block is positioned at over against the position of the recessed step in the dead bolt rear portion of stretching out state, and gangbar 10 is the subtended angle of about 90 degree, and two ends are hinged with locking slide block and unlatching slide block respectively, and the hinge hole is a flute profile, to adapt to the variation of distance between the slide block.
This routine course of work is: when locking a door, turning handle 16, connecting rod will act on the pin 7 of dead bolt upper process, dead bolt is moved outside lock housing, the also outwards motion thereupon of this end that elastic force lever and dead bolt are fixing, its other end is given and is opened inside thrust of slide block, makes it put aside certain spring force, and by gangbar 10 power is passed to the locking slide block.When dead bolt stretches out lock housing fully, when the recessed step in dead bolt rear portion was aimed at the locking slide block, the locking slide block of having put aside elastic force promptly sprang into the recessed step in dead bolt rear portion, and the locking dead bolt can not bounce back it.
When unblanking, rotational lock core plectrum 4, outwards stir and open slide block 5, open slide block and drive the locking slide block to leaving the motion of dead bolt direction by gangbar on the one hand, make the elastic force lever other end put aside certain spring force on the one hand, give the power of an inward direction of dead bolt, when the locking slide block breaks away from the dead bolt step fully, the dead bolt lock housing of promptly can under the elastic force effect of elastic force lever savings, withdrawing.If elastic force is big inadequately, turning handle can make the dead bolt withdrawal again.
