Summary of the invention
In order to overcome in the prior art common theft-proof door lock structure design comparison it is complicated, failure rate in use compared with
High problem, the utility model provide a kind of theft-proof door lock structure, and the structure design of the theft-proof door lock structure is simple and compact, electric
It moves, can open manually, high reliablity.
The technical scheme adopted by the utility model to solve the technical problem is as follows: including opposite in lock core body and lock core body set
The outside lock core shaft set and inside unlocking rod, the lock core body between outside lock core shaft and inside unlocking rod are equipped with unlocking thumb wheel,
The medial end of outside lock core shaft opens up the first groove, and press cap, the first spring and right drive block are set gradually in the first groove,
Right drive block is equipped with the driving block of protrusion, and driving block and the transmission of the first groove cooperate, and right drive block connects transmission simultaneously
Unlocking thumb wheel, inside unlocking rod open up second by Left Drive block connection transmission unlocking thumb wheel, the medial end of inside unlocking rod
The two sides cell wall of groove, the second groove hollows out to form driving groove, the tail end interval of Left Drive block two transmissions slide bars arranged symmetrically, and two
Transmission slide bar slides axially in opposite driving groove and forms the transmission cooperation of circumferencial direction, installs the between two transmission slide bars
Two springs, the natural length of second spring are greater than the length of transmission slide bar, sliding setting transmission on the epitaxy part of inside unlocking rod
Gear, transmission gear can form transmission cooperation with the locking platform snap lock being arranged on the unlocking rod epitaxy part of inside.
Relative to locking lever sleeve on the inside of one end fixed setting of outside lock core shaft in lock core body, inside unlocking rod and match
Left Drive block be rotationally installed in inside locking lever sleeve in.
The utility model can pass through unlocking rod on the inside of rotation when job failure occurs in motor by above-mentioned specific design
It unlocks manually, has the advantages that structure design is simple and compact, electronic, can open manually, high reliablity.
Detailed description of the invention
Illustrate the detailed content of the utility model below in conjunction with drawings and examples.
Fig. 1 is the decomposition texture schematic diagram of the utility model.
Fig. 2 is the assembling structure schematic diagram of the utility model.
Specific embodiment
As shown, the utility model includes the outside lock core shaft 2 being oppositely arranged in lock core body 1 and lock core body 1 and inside
Unlocking rod 3, lock core body 1 between outside lock core shaft 2 and inside unlocking rod 3 are equipped with unlocking thumb wheel 4, outside lock core shaft 2 it is interior
Side end opens up the first groove 5, and press cap 6, the first spring 7 and right drive block 8, right drive block 8 are set gradually in the first groove 5
It is equipped with the driving block 8A of protrusion, driving block 8A and the transmission of the first groove 5 cooperate, and right drive block 8 connects transmission simultaneously and opens
Thumb wheel 4 is locked, inside unlocking rod 3 opens up the by the connection transmission unlocking thumb wheel 4 of Left Drive block 9, the medial end of inside unlocking rod 3
Two grooves 10, the two sides cell wall of the second groove 10 hollow out to form driving groove 11, and the tail end interval of Left Drive block 9 is symmetrical arranged two and passes
Moving slide-bar 12, two transmission slide bars 12 slide axially in opposite driving groove 11 and form the transmission cooperation of circumferencial direction, and two pass
Second spring 13 is installed, the natural length of second spring 13 is greater than the length of transmission slide bar 12, and inside is unlocked between moving slide-bar 12
Sliding setting transmission gear 14 on the epitaxy part of bar 3, transmission gear 14 can be put down with the locking being arranged on 3 epitaxy part of inside unlocking rod
15 snap lock of platform forms transmission cooperation.Relative to locking lever sleeve on the inside of one end fixed setting of outside lock core shaft 2 in lock core body 1
16, inside unlocking rod 3 and the Left Drive block 9 matched are rotationally installed in the locking lever sleeve 16 of inside.In normal electric open-door
Under use state, the front end of Left Drive block 9 keeps engaging unlocking thumb wheel 4, forms transmission cooperation with unlocking thumb wheel 4.When enabling, electricity
Machine band nutating gear 14 rotates, and transmission gear 14 makes inside by the locking platform 15 being arranged on 3 epitaxy part of inside unlocking rod
Unlocking rod 3 rotates simultaneously, then is cooperated by the transmission that 9 tail end of Left Drive block is driven slide bar 12 and driving groove 11, and Left Drive block 9 makes
The rotation of unlocking thumb wheel 4 is unlocked.In electric open-door failure, key need to be inserted into outdoors by unlocking, and the key of insertion pushes press 6 He of cap
First spring 7, and right drive block 8 is promoted by press cap 6 and the first spring 7, right drive block 8 engages with unlocking thumb wheel 4, right biography
Motion block 8 pushes Left Drive block 9 that Left Drive block 9 is made to separate releasing transmission cooperation with unlocking thumb wheel 4 simultaneously, and key drives outside lock core
When axis 2 rotates, since the right drive block 8 of transmission effect of driving block 8A on right drive block 8 rotates simultaneously, right drive block 8 makes out
The rotation of thumb wheel 4 is locked to unlock.In electric open-door failure door drawback lock, inside unlocking rod 3 is manually advanced, is on the unlocking rod 3 of inside
Locking platform 15 separated with transmission gear 14, be rotated further by inside unlocking rod 3 when, pass through 9 tail end of Left Drive block be driven slide bar 12
Transmission with driving groove 11 cooperates, and Left Drive block 9 makes the rotation of unlocking thumb wheel 4 unlock.Embodiment described above is only to this
A kind of preferred embodiment of theft-proof door lock structure of utility model is described, and not carries out to the conception and scope of utility model
It limits, under the premise of not departing from the utility model, those skilled in the art make the technical solution of the utility model
Various external form variations and modifications, a kind of protection scope of theft-proof door lock structure of the utility model should all be fallen into.
