Technical Field
[0001] The utility model relates to the technical field of locks, in particular to a password lock which is highly versatile and easy to install. Background Art
[0002] In order to ensure that the inner door lock can be opened smoothly while the outer door lock is locked, the existing password lock adopts a method of designing the connecting shaft as a shaft body with two sections of mutually rotatable connection structure. The two ends of the shaft body of this structure cooperate with the inner door lock and the outer door lock respectively, and either end can control the opening and closing of the lock tongue. However, most of the shaft bodies are specially made for the lock body, and the shaft bodies generally available on the market are one-piece optical shafts. Therefore, their shape and size are generally different from the one-piece shafts commonly used on the market. When the outer door lock is to be replaced with a password lock or other lock body, the shaft body does not cooperate with the lock body to be replaced, which leads to the need to replace the entire inner and outer door locks and the shaft body, which increases the replacement cost. In addition, the installation steps of this type of shaft body are also relatively cumbersome, which makes the entire lock changing process troublesome, time-consuming and labor-intensive, and urgently needs to be improved.

[0004] By adopting the above technical solution, a mounting table with a movable groove is provided on the rotating block, and a rotor matching the commonly used integrated shaft on the market is provided in the movable groove. When the outer door lock of an ordinary lock is replaced with a password lock, there is no need to specially replace the two-section shaft body, but the original integrated shaft body can continue to be used. When the door handle of the outer door is turned, the rotating block drives the rotor to rotate together, and the handle of the inner door rotates synchronously. When the door is closed and the handle of the inner door is turned from the inside, since the outer door is in the locked state of the password lock at this time, the rotating block is locked. Turning the handle of the inner door drives the shaft to rotate and then drives the rotor to rotate. Since the rotor can rotate in the movable groove a distance matching the rotation angle of the handle, the handle of the inner door can be smoothly rotated to open the lock tongue, thereby completing the door opening action.
[0005] The utility model is further configured as follows: the rotor comprises a main body and a toggle block, the movable groove comprises a main body groove matching the main body and a rotation groove for rotating the toggle block, and the arc of the rotation groove matches the rotation angle of the handle.
[0006] Using the above technical solution, since the rotor includes a main body and a toggle block, the movable groove includes a main body groove matching the main body and a rotation groove for rotating the toggle block, and the curvature of the rotation groove matches the rotation angle of the handle, so that the toggle block can rotate in the rotation groove to match the rotation distance of the inner door handle.
[0007] The utility model is further configured as follows: the arc of the rotation groove is twice the rotation angle of the handle, the shape of the toggle block matches the rotation groove, and indicator marks for indicating the rotation direction of the inner door lock are respectively provided on both sides of the mounting hole of the mounting cover plate.
[0008] By adopting the above technical solution, since the curvature of the rotating groove is twice the rotation angle of the handle, the shape of the toggle block matches the rotating groove, and indicator marks for indicating the rotation direction of the inner door lock are provided on both sides of the mounting hole on the mounting cover plate, so that the direction of the initial position of the rotor in the rotating groove can be adjusted, thereby changing the rotation direction of the inner door handle. The inner door handle can be rotated clockwise or counterclockwise according to actual usage requirements.
[0009] The utility model is further configured as follows: an indicating notch for pointing to the indicating mark is provided at a hole corner of the square hole of the rotor opposite to the toggle block.
[0010] With the above technical solution, since an indicating notch for pointing to the indicating mark is provided at the hole corner opposite to the toggle block on the square hole of the rotor, it is possible to more clearly display which side the current rotation direction of the inner door handle is on when adjusting the rotation direction.
