[0007] The lock shell is installed with lock cylinder near indoor side, and the lock shell is installed with reverse locking mechanism that can be locked and cannot be rotated by inserting key into lock cylinder and rotating.

[0008] Further, the reverse locking mechanism includes gear box installed in the lock shell, the gear box is rotatably connected with rotating piece that can rotate with lock cylinder, and the lock shell is installed with reversing pusher, connecting pin and reversing piece with slot above gear box.

[0009] Further, the rotating piece is pushed up reversing pusher after rotating with lock cylinder, so that connecting pin moves to the slot of reversing piece, and handle is stuck and cannot be rotated.

[0010] III. Advantages

[0011] The utility model has the advantages that the intelligent lock is installed with lock cylinder and mechanical linkage reverse locking mechanism matched with lock cylinder in the inside of security door, connecting pin is inserted into the slot of reversing piece, and handle outside door is locked, even if the personnel who break in illegally outside inputs password, cannot rotate handle and open security door, which greatly protects the safety of occupants. BRIEF DESCRIPTION OF DRAWINGS

[0014] As shown in the figure: 1, handle, 2, lock shell, 3, reversing piece, 4, connecting pin, 5, reversing knob, 6, rotating piece, 7, gear box, 8, lock core. DETAILED DESCRIPTION

[0015] The utility model makes further detailed description in combination with the drawings.

[0016] To solve the above technical problems, the utility model provides a technical scheme for an intelligent lock, in combination with the drawings Figure 1 , including lock shell 2 and handle 1 rotatably connected to the lock shell 2 on the outdoor side, the normal locking state of the intelligent lock is released after inputting fingerprint, digital password, etc., and the handle 1 can be rotated to open the security door;

[0017] The lock core 8 is installed on the indoor side of the lock shell 2, and the anti-lock mechanism is installed in the lock shell 2 and can be rotated by inserting the key into the lock core 8, so that the handle 1 is locked and cannot be rotated;

[0018] In addition, a switch is arranged on the indoor side of the intelligent lock and the security door, the switch is installed with the lock core 8, and the switch can be rotated after the key is inserted, so as to increase a set of anti-lock system, the security door is locked in the room, the security door cannot be opened on the outdoor side, and the safety of the indoor side is ensured in some special cases;

[0019] The anti-lock mechanism includes the gear box 7 installed in the lock shell 2, the rotating piece 6 rotatably connected in the gear box 7 and capable of rotating together with the lock core 8, and the reversing knob 5, the connecting pin 4 and the reversing piece 3 with the clamping groove installed in sequence above the gear box 7 of the lock shell 2;

[0020] After the rotating piece 6 rotates with the lock core 8, the reversing knob 5 is pushed up, the connecting pin 4 is moved to the clamping groove of the reversing piece 3, the handle 1 is clamped and cannot be rotated, the electronic function such as fingerprint card password cannot be used to lock, the door outside anti-lock effect is achieved, abnormal unlocking behavior can be effectively and timely responded, or the outer door anti-lock can be quickly realized.

[0021] The utility model discloses when the door lock password of inputting number, fingerprint etc. is tried to open the intelligent lock and the security door when finding the stranger outside the door, and the indoor personnel can quickly insert the key into the lock core 8 and rotate, and the rotating piece 6 in the gear box 7 is completed in a flash, and the connecting pin 4 is made to go up to the clamping groove of the reversing piece 3 through the poking piece, and the handle 1 is clamped and locked to realize that the stranger who is opening the lock outside cannot rotate the handle 1, opens the door, breaks into the indoor illegally, and further protects the safety, avoids falling into the dangerous situation.

[0022] The above describes the utility model and its implementation mode, and this description is not restrictive, and the embodiment shown in the drawings is only one of the utility model, and the actual structure is not limited thereto. In summary, if the ordinary skilled person in the art is inspired, without departing from the utility model creation tenet, the similar structure mode and the embodiment are not designed creatively, and all belong to the protection scope of the utility model.
