The other is a second strip 32, which is shorter than the first strip 31 for the convenience of turning the cover plate 3 over.

The joint of the bottom surface of the cover plate 3 and the first clamping strip 31 is provided with a thumb groove 33 which is convenient for fingers to insert.

An indication strip 20 is arranged on the outer side wall of the runner 2 at the position of the pin hole 21, and the indication strip 20 is used for marking the position of the pin hole 21, so that the positioning is performed quickly and accurately.

The mechanical lock comprises a lock sleeve 5 sleeved outside a lock cylinder 4, a lock block is clamped in the lock cylinder 4, and the mechanical lock is matched with the lock sleeve 5 to realize the function of the mechanical lock; a key is inserted into the lock hole 41 to jack up the lock block, thereby completing the unlocking function.

A locking groove 51 is formed outside the lock sleeve 5, the electronic lock comprises an electromagnetic limiting device 6, and the electromagnetic limiting device 6 controllably extends or retracts a locking rod 61; when the locking rod 61 is inserted into the locking groove 51, the rotation of the lock sleeve 5 is limited so as to realize locking, and when the locking rod 61 is separated from the locking groove 51, the unlocking is realized.

The casing 1 is provided with a touch panel 11 for inputting a password, and the touch panel 11 can drive the electromagnetic limiting device 6 to retract the locking rod 61 after the correct password is input.

The back of the shell 1 is in bolted connection with a back cover plate 13, at least one of the width and the length of the back cover plate 13 is larger than the numerical value of the corresponding width or the corresponding length of the shell 1, at least one of the width and the length of the touch panel 11 is larger than the numerical value of the corresponding width or the corresponding length of the shell 1, and the back cover plate 13 is matched with the touch panel 11 to fix the shell 1 on a wood board, so that the shell 1 is installed on a wooden door; the door plate is characterized in that a plurality of side clamping blocks 14 are arranged on two outer side walls of the shell 1, one end parts of the side clamping blocks 14 are not in contact with the outer side walls in a tilting mode, and the side clamping blocks 14 can be clamped on a steel plate, so that the shell 1 can be installed on a door plate made of metal materials such as steel.

The tail end of the lock cylinder 4 is connected with a lock shaft 8, and the lock shaft 8 is used for connecting a lock plate; be provided with a plurality of recesses 81 on the lock axle 8, be located in the casing 1 lock axle 8 side is provided with support 7, be provided with kicking block 71 in the support 7, kicking block 71 tip volume dwindles gradually and forms the constriction, the constriction can be gone into in the recess 81, kicking block 71 tail end is provided with the spring, the spring promotes kicking block 71 to 8 axle center directions of lock axle remove.

The rotating wheel 2 of the device is arranged outside the lock sleeve 5, and the rotating wheel and the lock sleeve can synchronously rotate. The device is internally provided with two sets of locking and unlocking mechanisms, one set is an electronic lock, and the other set is a mechanical lock.

The mechanical lock comprises a lock core and a lock block which are arranged in a lock sleeve 5. When locking, the locking block is clamped in the lock core 4, so that the lock core 4 and the lock sleeve 5 cannot rotate relatively. And the lock sleeve 5 is clamped by the electromagnetic limiting device and cannot rotate, so that the locking work is finished. When unlocking, a key is inserted into the lock cylinder 4 to eject the lock block, so that the lock cylinder 4 and the lock sleeve 5 can rotate relatively, the lock cylinder 4 is rotated, and unlocking is realized.

The electronic lock mainly uses an electromagnetic limiting device to extend and retract the locking rod 61 and match the locking groove 51 on the lock sleeve 5, so as to lock and unlock the lock sleeve 5. When unlocking, the electromagnetic limiting device retracts into the locking rod 61, so that the electromagnetic limiting device is not clamped in the locking groove 51 any more, and therefore the lock sleeve 5 can drive the lock cylinder 4 to rotate together, and unlocking is completed.

The device is unlocked by using the password at ordinary times. The user inputs the password through the touch panel, and if the password is correct, the electromagnetic limiting device is started to work, and the locking rod 61 which extends out when the locking rod is retracted and is clamped into the locking groove 51 is locked. After the locking rod 61 leaves from the locking groove, the user can unlock the door by rotating the rotary wheel 2.

If the built-in battery power of this device runs out, pull down the charging seat match, expose the back of charging inside, then can supply power for this device through treasured or other equipment that charge to can continue to use the electron unblock.

If the power supply is unavailable or the electronic lock mechanism fails, the unlocking can be performed in a mechanical mode.

The device hides the mechanical unlocking mode for aesthetic appearance and safety. Specifically, the cover plate 3 is engaged with the runner 2 so as to cover the end surface of the key cylinder 4 and the lock hole 41 into which the key is inserted. With this arrangement, it is difficult to see that the mechanical unlocking mode can be adopted from the appearance. Namely, the hidden purpose is realized.

When mechanical unlocking is required, a rigid rod-shaped object with a consistent diameter, such as a pin, a poking needle or a nail, is inserted into the pin insertion hole 21 and pushes against the inclined block 311 to bend the first clamping strip 31. Because of the effect of the inclined surface of the inclined block 311, after the rigid rod-shaped object is inserted, the rigid rod-shaped object can move up against the inclined block 311, and because the first clamping strip 31 is bent, the rigid rod-shaped object is not blocked by the limiting blocking strip 221 any more, so that the side of the cover plate 3 is pushed up, and the thumb groove 33 is exposed. The cover plate 3 can then be removed by applying a finger to the thumb groove 33, exposing the locking hole 41. Thus, the mechanical unlocking can be carried out by using the key.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. The scope of the invention is indicated by the appended claims, rather than the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
