Description
Technical field
The utility model relates to a kind of electronic lock, especially it is a kind of can be improved anti-theft grade with emergent unlocking function
Electronic lock.
Background technique
Electronic lock is appreciated because eliminating the worry of carrying keys, therefore mechanical lock is transformed and is risen by more and more people's selection
Grade is electronic lock.There are many existing reforming modes, and basic structure is that motor is fixed in lock housing, the worm screw to connect with motor
It is engaged with worm gear, worm gear is coaxially connected with a gear, which engages with coaxially connected one of two reduction gearing, another to subtract
Fast gear is engaged with lock core driving gear, and lock core driving gear is fixedly connected with lock core；Motor connects with control circuit, in lock housing
It is additionally provided with lever-type clutch outside.When outdoor needs are opened/locked a door, password or fingerprint, control circuit and setting are inputted
Password or fingerprint are compared, and such as coincide, then control motor forward or reverse, open/lock a door by gear drive realization；When open/
After locking a door in place, stall occurs for motor, and when control circuit detects that motor rotation blockage electric current is more than predetermined value, control motor stops turning
It is dynamic；Interior is constant by way of unlocking.When motor runs out of steam source, by lever-type clutch make mechanical driving part with
Lock core separation realizes that mechanical emergency is unlocked.But since lever-type clutch is arranged outside lock housing, in addition by lock housing volume
Limitation, the lock core of lever rod-type clutch is very small, and therefore, anti-theft performance is poor, reduces the anti-theft grade of lock.
Summary of the invention
The utility model be in order to solve above-mentioned technical problem present in the prior art, provide one kind can be improved it is antitheft etc.
The electronic lock with emergent unlocking function of grade.
The technical solution of the utility model is: a kind of electronics with emergent unlocking function that anti-theft grade can be improved
Lock, has lock housing, motor is fixed in lock housing, engage with the worm and wheel that motor connects, and worm gear shaft is connected with first gear,
The first gear is engaged with second gear, is fixed with central axis in lock housing, and the lower end sliding of the central axis is connected to the
Three gears, the third gear, which is fixed on, slides the sliding sleeve to connect with central axis, and the second gear is located at third gear
Top and with sliding sleeve sliding connect, on second gear be equipped with soft iron suction sheet, on soft iron suction sheet be equipped with center and cunning
The soft iron absorption circle being fixedly connected is covered, the electromagnetic coil being fixed in lock housing, the third gear are built-in in soft iron absorption circle
It is engaged with the 4th gear, the 4th gear is fixedly connected with lock core.
The utility model is that the structure that can make motor drive and lock core clutch is provided in lock housing, that is, password can be used or refer to
Line etc. is electronically opened/is locked a door, and key is not necessarily to, very convenient, and can realize mechanical system with key when surprisingly losing power supply
It opens/locks a door, realize emergent unlocking.All components of especially the utility model are mounted in lock housing, securely and reliably, are improved
The anti-theft grade of lock.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the schematic diagram of internal structure of the utility model embodiment.
Specific embodiment
The electronic lock with emergent unlocking function that anti-theft grade can be improved of the utility model, it is same as the prior art
It is to have lock housing 1, motor 2 is fixed in lock housing 1, is engaged with the worm screw 3 that motor 2 connects with worm gear 4, worm gear 4 is coaxially connected with
First gear 5, first gear 5 are engaged with second gear 6, with the prior art except that being fixed with central axis in lock housing 1
7, the lower end sliding of central axis 7 is connected to third gear 8, and third gear 8, which is fixed on, slides the sliding sleeve to connect with central axis 7
9, second gear 6 is located at 8 top of third gear and connects with the sliding of sliding sleeve 9, and soft iron suction sheet is equipped on second gear 6
10, the soft iron absorption circle 11 that the center that is equipped on soft iron suction sheet 10 is fixedly connected with sliding sleeve 9 is built-in in soft iron absorption circle 11
The electromagnetic coil 12 being fixed in lock housing 1, third gear 8 are engaged with the 4th gear 13, the 4th gear 13 and 14 stationary phase of lock core
It connects.It is connected to control circuit with motor 2, electromagnetic coil 12 also connects with control circuit.
The course of work is as follows:
1. when outdoor needs are opened/locked a door, input password or fingerprint, the password or fingerprint of control circuit and setting into
Row compares, and such as coincide, then controls motor 2 forward or reverse, while control circuit control electromagnetic coil 12 charges.Motor 1 passes through
Worm screw 3 drives worm gear 4 to rotate, and rotates second gear 6 by first gear 5.At this point, since the electrification of electromagnetic coil 12 then makes
Soft iron suction sheet 10 and soft iron absorption circle 11 magnetize and are mutually attracted one, and second gear 6 then by soft iron absorption circle 11 and is slided
Set 9 drives third gear 8 to rotate, and third gear 8 drives the 4th gear 13 to rotate lock core 14, then realizes and opens/lock a door.
2. such as lose power supply because unexpected, 12 power loss of magnetic coil, soft iron suction sheet 10 and soft iron absorption circle 11 lose magnetization and
It separates, third gear 8 is not then controlled random rotation by second gear 6.It is rotated at this point, control lock core 14 can be rotated by key,
Then it realizes and opens/lock a door.
It opens/locks a door in place afterwards to motor control and indoor unlocking mode compared with technology.
