Background technique

With the development of the economy, the electronically controlled door locks with building intercom come into use, replacing the traditional door locks, which facilitates people's lives. The electric control lock on the electric control door of the building uses the coil to energize to generate a magnetic field to displace the core magnet, release the trip, and then return the deadbolt to open the door. When the electric control lock closes the door, the deadbolt collides with the door frame and the spring Rapid ejection and collision of related parts will make loud noises, causing noise pollution and seriously affecting people's production, life and rest. Another type of lock is a magnetic lock, which requires long-term power supply, which consumes a lot of power and is expensive to manufacture. The motor lock is a new product developed according to the working principle of the electric control door of the building, combining the advantages of the electric control lock and the magnetic force lock, and overcoming their shortcomings. The performance is more perfect and the advantages are more obvious.

At present, the motor locks on the market generally use electronic control circuits to control the motor, and can be locked and unlocked manually when the power is off. This motor lock generally comprises motor, gear set, connecting rod, dead bolt, knob etc., and motor drives connecting rod to move through gear set, thereby realizes locking and unlocking of dead bolt. The gear set of this type of lock is generally equipped with multi-stage gears, the number of gears is large, the structure is complex, and the mechanical space occupied is large; , The knob of the manual mechanism is forced to turn, long-term use will easily damage the manual mechanism and shorten the service life of the motor lock manual mechanism.

Contents of the invention

In view of the technical problems existing in the prior art, the present invention provides a novel motor anti-theft lock, which is a motor lock with compact structure, long service life and manual and electric combination.

For realizing above-mentioned technical purpose, the technical scheme that the present invention adopts is as follows:

With the motor anti-theft lock of the above technical solution, when the door is in the locked state, since the door frame is provided with a corresponding lock hole at the corresponding dead bolt, and there is no lock hole at the corresponding control tongue, at this time, the dead bolt is in the extended state, and The control tongue is in the retracted state due to the action of the door frame, that is, the dead bolt protrudes and is stuck in the door frame, and the door cannot be opened. At this time, the motor is not energized, the return spring of the deadbolt lever is in a non-compressed state, the return spring of the transmission rod is in a compressed state, the movable shaft spring of the motor transmission mechanism is in a non-compressed state, and the upper end of the movable shaft fits against the transmission clutch control mechanism At the small-diameter portion of the cylindrical column, the clutch pin is at the upper end of the movable bar hole and inserted into the U-shaped groove of the clutch driven gear. The driving gear is in a state capable of driving the clutch driving gear no matter directly or indirectly. , the rack meshes with the clutch driven gear, the first end of the transmission fork is rotatably connected to the lock housing through the fork pin shaft, the second end is mated with the lock bolt control end, and the rack and The transmission fork is matched and connected.

When the door needs to be opened, it is first necessary to give the motor a starting power signal through the power signal control mechanism (the power can be turned on by using a switch or a signal start). After the motor is powered on, it drives the driving gear connected to the output shaft of the motor. Then drive the clutch driving gear to rotate, and at the same time drive the rack to move to the right, and the rack drives the transmission fork to rotate counterclockwise, thereby driving the latch lever to move to the right as a whole. During this process, the return spring of the latch lever is gradually compressed until The lock tongue is completely out of the door frame and is in the retracted state, and the door can be opened at this time; of course, because the position sensor can be used in the design to give the position signal, when the lock tongue is in a certain position in the retracted state, the motor will stop running immediately, and The tension to the left of the return spring of the deadbolt bar can be reasonably designed so that the tension and the rightward movement of the rack form a dynamic balance, so that the deadbolt has a distance-limited movement to the right.

When the door is opened, due to the return action of the transmission rod return spring, the control tongue will naturally stretch out to the left without the constraint of the door frame, driving the control tongue transmission rod to move to the left, and the upper end of the movable shaft is gradually pressed against by the fitting. The small-diameter portion of the cylindrical column of the transmission clutch control mechanism becomes fit against the large-diameter portion of the cylindrical column of the transmission clutch control mechanism. At the same time, the movable shaft drives the clutch pin to move downward, compressing the movable shaft spring. At this time, the movable shaft spring is in the In the compressed state, the clutch pin breaks out of the U-shaped groove, the driving gear is disengaged from the clutch driving gear, the clutch driven gear has no power input, and is in an empty sleeve and is radially fixed on the shaft sleeve; the return spring of the deadbolt lever Under the action, the dead bolt will also be in the state of stretching out to the left. At this time, the motor can be given a closed power signal through the power signal control mechanism (the switch can be used to disconnect the power supply or the signal can be started to disconnect the power supply).

When you need to close the door again, you only need to close the door directly like an ordinary anti-theft door. After the rod return spring retracts, it stretches out at the corresponding lock hole again, and the control tongue overcomes the transmission rod return spring and is in a compressed state. Complete a cycle from locking the door to unlocking the door to locking the door.

Compared with the prior art, the present invention has the advantages of simple design structure, compact layout and convenient operation; electric unlocking avoids the trouble of carrying keys for mechanical unlocking, and is more intelligent. The power signal control mechanism of the present invention can adopt power control, fingerprint control or face recognition control, etc., as long as a signal can be given to prompt the motor to start or close.

Further, the motor anti-theft lock in the above technical solution also includes a manual lock cylinder and a manual lock cylinder toggle plate, one end of the manual lock cylinder toggle plate is rotatably and flexibly connected to the lock housing through the pin shaft of the toggle plate, The other end of the manual lock cylinder toggle plate is matched with the dead bolt control end.

The above technical solution can further ensure that the door can still be opened manually when the power signal control mechanism cannot give a signal to prompt the motor to start or close, which is more convenient for users to use.

Of course, it can be further defined that the manual lock cylinder adopts a one-way ratchet structure, that is, a one-way ratchet is sheathed on the outside of the manual lock cylinder, and the outside of the one-way ratchet interacts with the manual lock cylinder toggle plate. This kind of manual lock cylinder toggle plate is driven in one direction, that is, when the key is used to open the door, the manual lock cylinder rotates to drive the manual lock cylinder toggle plate so that the lock tongue is retracted, and the door is in an openable state; but when the lock tongue is activated by the power signal When the control mechanism controls retraction, the manual lock cylinder toggle plate will not drive the manual lock cylinder to rotate. This structure can adopt various methods such as one-way ratchet. The structure of this one-way ratchet is the prior art, and it is here No restrictions. This kind of technical scheme mechanical unlocking and electric opening and locking are two independent systems. Even in the case of power failure, the anti-theft lock can be opened with a key, and the electric unlocking avoids the trouble of carrying a key for mechanical unlocking, making it easier , the combination of the two also reduces the friction of the mechanical lock cylinder, and the service life is longer.

Furthermore, in consideration of safety, to prevent others from using a thin card to directly flip the lock tongue in reverse to open the door lock, on the basis of the above technical solution, it is further defined that the transmission fork is also provided with a third end The transmission clutch control mechanism also includes a lock card, the middle part of the lock card is rotatably connected to the lock housing through the lock card pin shaft, the left end of the lock card can be disengaged against the lock tongue, and the right end of the lock card is connected to the lock tongue. The third end of the transmission shift fork cooperates and interlocks, the installation position of the lock pin shaft is above the telescopic movement direction of the lock cylinder, the left end of the lock card is located at the lower left of the lock pin shaft, and the left end is supported on the At the right end of the lock bolt; the right end of the lock card is located at the lower part of the third end of the transmission fork. When the lock card of this structure is opened in the forward direction, the transmission fork rotates counterclockwise, and the lock card is pushed to rotate clockwise, that is The right end head of the lock card moves downwards, and the left end head of the lock card (55) moves upwards in the lower left direction of the lock card pin shaft, and breaks out of the support portion, and the dead bolt can move to the right, thereby opening the door; When the lock tongue can move to the right, push the lock card to rotate counterclockwise, and the left end head is located at the lower left of the lock card pin shaft to move downward, thereby pushing the transmission fork to rotate clockwise, and the transmission fork to rotate clockwise Push the dead bolt to move to the left in turn to form opposite forces, thereby ensuring that the dead bolt cannot fully withdraw from the door frame, so the door cannot be opened in one direction.

It is further defined that the motor transmission mechanism further includes a driven gear, the driven gear meshes with the driving gear and is fixed on the left side of the driving gear, and the clutch driving gear meshes with the driven gear and is fixed on the left side of the driven gear. The use of driven gears for specific transition indirect connection, on the one hand, can optimize the layout position, so that the rack can be better arranged, to ensure the consistency of the rotation direction after the secondary transmission, on the other hand, it can be achieved through the driven gear The adjustment of speed and torque is usually to reduce the speed and increase the torque, so as to facilitate the selection of the speed and power of the motor.

Further, it is specifically defined that the clutch driven gear is a convex gear, and the U-shaped groove is placed in the protrusion of the clutch driven gear. The gear of this structure is convenient to process.

Furthermore, it is defined that a return torsion spring is sleeved on the pin shaft of the shift fork, the pin shaft of the toggle plate and the pin shaft of the locking card. A bearing is also arranged inside the clutch driving gear; a thrust bearing sleeved on the shaft sleeve is also arranged between the clutch driving gear and the clutch driven gear.

In addition, the specific mounting plate is limited, and the lock housing is defined to be provided with a motor suspension plate, a transmission rod suspension plate, and a transmission shaft fixing plate, and the motor and the clutch transmission group are fixed on the motor suspension plate; The rod part is fixed on one end of the transmission rod suspension plate, the two ends of the transmission rod return spring are respectively against the control tongue and the transmission rod suspension plate, the other end of the transmission rod suspension plate is docked and fixed with the transmission shaft fixing plate, and the motor suspension The plate is fixed vertically to the transmission rod suspension plate, and the motor suspension plate is located between the control tongue transmission rod and the transmission shaft fixed plate. One end of the shaft sleeve of the clutch transmission group is fixed on the transmission shaft fixed plate, and the other end passes through the motor. The hanging plate is connected with the round table column.

With the mounting plate of such a structure, the motor is in a suspended state relative to the lock housing, which facilitates the setting of the transmission shift fork, saves the space of the anti-theft lock, and has a compact and reasonable layout.
