[0065] The indicator 4 faces the observation window 3, and a deadbolt indicator area and an unlock indicator area are arranged sequentially along the length of the indicator 4;

[0066] Specifically, when the indicator 4 is in the first position, the unlocking indicator area is directly opposite the observation window 3; when the indicator 4 is in the second position, the deadbolt indicator area is directly opposite the observation window 3.

[0067] In the above technical solution, the horizontal height of the observation window is higher than the horizontal height of the inner door handle. In order to adapt to the different installation orientations of the inner door handle, two observation windows can be provided. The horizontal height of the other observation window is lower than the horizontal height of the inner door handle. Therefore, the inner mounting base is provided with two indicators, two protrusions, two arc-shaped through grooves and two push blocks corresponding to the two observation windows. The components corresponding to the two observation windows are rotationally symmetrical.

[0068] By adopting the above technical solution, in actual production, the deadbolt indicator area is painted red, and the unlock indicator area is painted with a filter color to distinguish the door lock status.
