Description

Lock cylinder fixed cross mechanical anti-theft lock matched with fingerprint lock

technical field

The utility model relates to the field of anti-theft locks, in particular to a lock core fixed cross mechanical anti-theft lock matched with a fingerprint lock.

Background technique

Fingerprint lock is a special product that is a perfect combination of computer information technology, electronic technology, mechanical technology and modern hardware technology. Because of the convenience of using fingerprint recognition technology to unlock the lock and as a symbol of high-end smart locks, the market share is about 5%. rising trend. The technical standards of fingerprint locks are mainly based on the national public security industry standard "General Technical Conditions for Fingerprint Anti-theft Locks" (GA701-2007). In addition to convenience, what consumers value most is the overall anti-theft performance and anti-vandalism of fingerprint locks. Performance, but these two indicators contain many factors, and it is not easy to draw conclusions, because according to national regulations, out of safety and other factors, fingerprint locks must be equipped with mechanical keys, that is, fingerprint locks can also be unlocked by inserting mechanical keys. Therefore, the various performances of a full set of fingerprint locks, especially the anti-theft opening performance (including anti-technical opening, anti-destructive opening, etc.) can only depend on the shortcomings of the two.

At present, there are many kinds of fingerprint locks on the market, the quality is uneven, and the price ranges from a few hundred yuan to several thousand yuan, which makes consumers at a loss and difficult to choose when purchasing goods. The main performance of the identification system and electronic control part of the fingerprint lock includes the accuracy of fingerprint identification, the stability of electronic components, the material and mechanical strength of the main components, etc., and there are great differences between different brands. The mechanical lock part includes the lock body and the lock cylinder. Although the quality of the former is different, the difference in price is limited; "Grade", etc., the price difference is relatively large, so the overall performance, quality and price of fingerprint locks on the market currently vary greatly.

Under normal circumstances, when the fingerprint identification or password identification is correct, the motor clutch or electromagnetic clutch is closed, and the unlocking is completed by rotating the handle in the positive direction; when the key is used to unlock the lock, it is completed by inserting the key and rotating the key; locking At the same time, it is completed by rotating the handle in the opposite direction (that is, lifting the handle), or it will be automatically locked when the door is closed.

The locking mechanism of the fingerprint lock has a big difference in structure, mainly due to the difference in the installation position of the lock cylinder, motor clutch or electromagnetic clutch: the lock cylinder is installed in the lock body, that is, the mortise type, the mechanism is relatively complicated, and the cost is relatively high. High, but because the lock body is inside the door leaf, the overall anti-destructive opening performance of the fingerprint lock is relatively high; the lock cylinder is installed inside the outer panel of the fingerprint lock outside the door leaf, and the rotation of the lock cylinder passes through a connecting rod (mostly flat) Or square rod shape) is movably inserted into the lock body and transmits power. When the outer panel of the fingerprint lock is damaged, the lock can be opened directly, so the anti-destructive opening performance is relatively low. The motor clutch or electromagnetic clutch is installed in the lock body, and the lock body is located in the door leaf. It is relatively difficult to close the clutch by destroying the lock body, that is, the anti-destructive opening performance is relatively high; the motor clutch or electromagnetic clutch is installed in the fingerprint lock. In the outer panel of the lock, the inner side of the handle seat is movably inserted into the lock body through a shaft and transmits the rotational movement of the handle, the structure of the lock body is simplified and the cost is reduced, but when the outer panel of the fingerprint lock is damaged, the lock can be opened directly , so the anti-destructive opening performance is relatively low. In particular, even if the electromagnetic clutch is not energized, it may be closed by relying on an external strong magnetic field, so the electromagnetic clutch installed in the outer panel of the fingerprint lock is less secure.

In the above mechanism, whether the lock cylinder is installed in the outer panel or in the lock body, the anti-opening performance of the lock cylinder depends on the level of the lock cylinder itself, and has nothing to do with the installation position; the anti-drilling function of the lock cylinder depends on the outside of the key socket. Whether the anti-drilling sheet or protective device is installed, the material and mechanical strength of the anti-drilling sheet or protective device, and the mechanical strength of the lock cylinder itself have nothing to do with the installation position; the destructive opening performance of the lock cylinder anti-forced opening tool depends on its own material , mechanical strength and whether there is an anti-prying device has nothing to do with the installation location.

In addition, the fingerprint lock in the prior art is completed by rotating the handle when the fingerprint and password are used to unlock the lock. When the fingerprint and password are incorrect, the handle only rotates at a certain angle. When the handle is continued to be rotated forcibly, it will be destroyed The relevant parts of the lock; when the spare key is used to unlock the lock, it is completed by rotating the key. When the key is incorrect or there is no key, the lock cylinder cannot be rotated, which provides a fulcrum for the forced opening tool to destroy the lock cylinder and open the lock.

Two invention patents of "a cross mechanical anti-theft lock with fixed lock cylinder" (patent number ZL201410020215.X) and "double-insert anti-theft door and external locking device" (application number 201610129609.8), both of which have special structures and performances , and achieved the expected use effect. Among them, the cross mechanical anti-theft lock has the characteristics that it cannot be opened by technology, cannot be destroyed by force-opening tools, the handle has an overload protection device that can idle, the key volume is large, the key can be represented by a digital code, and the performance is stable and reliable. , simple and easy operation, etc., especially the key is only plugged in, not rotated, and the characteristics of unlocking the lock by rotating the handle are the same as that of the fingerprint lock identification system or password identification system, which is finally unlocked by rotating the handle; the double-plug security door as a whole Good rigidity, high mechanical strength, strong anti-prying performance, and the movable connection between the lock bolt, the lock tongue and the lock external is more conducive to protecting the lock and so on. However, the above two patents only describe the technical characteristics of the cross mechanical anti-theft lock and its supporting anti-theft door (including the external locking device), and do not mention the supporting use scheme with the fingerprint lock, let alone the combination with the fingerprint lock. The structural characteristics and performance characteristics of the new products after matching.

According to the above-mentioned scheme, whether the lockset of the present utility model utilizes fingerprint unlocking, password unlocking or key unlocking and locking operations, it is all completed by rotating the same handle, while also retaining the unique performance of the original cross mechanical anti-theft lock. Therefore, the cam mechanism connected with the handle of the lockset of the present utility model has the following six functions or characteristics: one is that the handle can be locked by anti-lifting; The handle can unlock the lock; the third is that no matter whether the fingerprint identification and password identification system can work normally, the lock can be unlocked by inserting the correct key and rotating the handle; the fourth is that the fingerprint, password, and key are not correct, and the lock cannot be unlocked; The unlocking operation after password identification and the key unlocking operation do not interfere or affect each other; Sixth, when the handle is twisted forcefully, the handle can rotate idly.

The specific operation process and principle are as follows:

1. Locking operation process: In static state, the two clutches are in the disengaged state. When the handle is rotated in the reverse direction, the driven ring and the reverse drive plate follow the reverse rotation, and the push column of the reverse drive plate pushes the pendulum in the reverse direction. Swing, the pendulum rod pushes the main pull plate upwards through the driving opening, and the main pull plate then pushes the sky rod in the sky and earth rod to run upwards. At the same time, the main pull plate pushes the T-shaped rotating plate to reverse Rotate in the opposite direction, the left end of the T-shaped rotating plate pushes the auxiliary pull plate to move downward, and then pushes the ground rod in the sky-earth rod to move downward, and the upper end of the T-shaped rotating plate also pushes the main push pin and the main lock bolt at the same time Move to the left to complete the locking action, and then the handle is reset under the action of the driven ring's two-way reset coil spring;

2. The key unlocking process: under static conditions, insert the key, the key pushes the keyhole push pin in the keyhole connecting ring to move inward, and the keyhole push pin pushes the auxiliary clutch push pin and the auxiliary clutch gear pin to move through the spring lever to make the auxiliary clutch The gear pin is inserted into the linkage hole of the driven ring. At this time, the handle is rotated forward, and the driven ring pushes the cam ring to rotate through the auxiliary clutch pin. Touch the left side of the key, and then push the dial and the positive drive plate to rotate forward. If the key is correct, the outer rotating ring can rotate the whole way, and then can push the swing rod to swing forward. The swing rod pushes the main pull plate to run downward through the drive opening. , the main pull plate then pulls the sky rod in the sky and earth rod to run downwards. At the same time, the main pull plate pushes the T-shaped rotary plate to rotate forward through the follow-up opening on the main push slider, and the left end of the T-shaped rotary plate is then Push the auxiliary pull plate to move upward, and then push the ground rod in the sky and earth rod to run upward. The T-shaped rotating plate also pushes the main push pin and the main lock bolt to move to the right at the same time. end drives the main linkage piece, linkage shaft, and auxiliary linkage piece to rotate, and then pulls the bolt back to complete the unlocking action. The moving ring resets under the action of the two-way reset coil spring; if the key is incorrect, the outer rotating ring cannot continue to rotate independently, and the locking column prevents the cam ring, dial wheel and forward drive plate from continuing to rotate, and the lock cannot be opened.

During the above-mentioned unlocking process, after the cam ring rotates, one end of the auxiliary clutch pin is inserted into the linkage hole of the driven ring, and the other end is in active contact with the back plate, so that the unlocking operation will not be interrupted. When the cam ring is reset and the key is drawn out, Only then can it be pulled out from the linkage hole of the driven ring, and then reversely inserted back into the port of the auxiliary clutch connecting ring. Since the key of the lockset of the utility model can only be drawn out when the cam ring, dial ring, inner rotating ring, and outer rotating ring are all reset, so as long as the key is not forgotten, no matter whether the secondary clutch pin is inserted into the linkage hole of the driven ring , the lock cannot be opened again without the correct key. For example: after opening the lock, the key is not drawn out, the handle is reset and then the handle is rotated in the opposite direction, the secondary clutch gear pin is still inserted into the linkage hole of the driven ring, although the key can be drawn out afterwards, but if you want to complete the main lock bolt or The retraction action of the deadbolt must make the cam ring complete the full forward rotation again, so if the key is not inserted again, the lockset cannot be opened again.

3. Fingerprint and password unlocking process: When the fingerprint recognition is correct or the password is correct, the motor is energized and rotated, and the motor transmission device pushes the gear pin to move inward, the gear pin is inserted into the notch of the step shaft, and then the handle is rotated forward , the driven ring pushes the dial and the positive drive plate to rotate, and then pushes the pendulum to swing forward. The unlocking action is completed in the same principle as above, and then the handle is reset; if the fingerprint identification or password is incorrect, the motor transmission device cannot push the lock. The stop pin moves to the inner side, and at this time, the handle is rotated in the forward direction, the handle and the driven ring rotate idly, and the lock cannot be opened. The handle and the driven ring rotate idly in the forward direction until they come into contact with the limit post of the driven ring to stop the rotation, otherwise, the counter-drive disc push post can also push the fork to rotate forward to unlock.

During the above-mentioned various operations, if the handle cannot rotate normally or has been rotated to the end normally but the handle is still twisted strongly, the active piece in the torque limiter will overcome the thrust of the thrust spring or disc spring and the driven piece, from The moving cover slips, and the handle can be idling. When the hand is idling, the steel ball moves in a circle with the active piece, and moves axially from the moving piece, while the steel ball of "a type of cross mechanical anti-theft lock with a fixed lock cylinder" only returns to the hole and does not follow the active piece. Significant changes exist. The main reason for this change is that the cam mechanism of this scheme needs to realize many functions, and the structural space layout is very compact. There is no space for each steel ball to be equipped with a push spring respectively, but the effect is the same.

In particular, the lower part of the outer panel of the lock of the utility model includes the center of the key hole, and a lower sliding cover can be added. When unlocking with a mechanical key, first push the lower sliding cover downward to expose the lock hole and then insert the key. In addition, in the downward sliding mechanism of the lower slide cover, a check mark type lock hole protector can also be added. Through the slide cover knob located below, the check mark rotation can be performed in forward and reverse directions or in multiple directions. Only when the check mark is correct, the lower part Slide cover just can slide down, check mark is incorrect, lower slide cover can not slide, and lock hole can not be exposed, in order to protect lock hole.

The beneficial effects of the utility model are:

1. By adopting the cam mechanism with special structure, the whole set of fingerprint lock retains the unique technology of "a cross mechanical anti-theft lock with fixed lock cylinder" due to the key unlocking mechanism, and has the same anti-technical opening, anti-forced opening, Performance features such as a large amount of keys and the handle can be idling, so that the key unlocking part is no longer a technical shortcoming, and the overall performance indicators of the fingerprint lock are significantly enhanced;

2. The whole set of fingerprint locks retains the unique technology that the lock bolt and bolt of the "double-insert anti-theft door and external hanging locking device" are connected with the external hanging type of the lock, so the anti-prying and anti-destructive performance of the lock is also significantly improved. ;

3. Fingerprint recognition unlocking, key insertion unlocking and locking operations are all done through the same handle, the overall lock operation is simple and easy, and the overall cost does not change significantly.
