[0031] It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0032] See also Figures 1 to 11 The utility model relates to an opening and closing indication handle, which, when applied to doors and windows, can display the state of the door and window where the handle is located through the built-in opening and closing indication component 40, such as displaying whether the door and window is in a locked state or an openable state, so that the user can understand the state of the door and window through the handle, thereby improving safety and interest.

[0033] In one embodiment, the utility model uses the open and closed state of the adjustable iris 41 to indicate the state of the door and window. When the adjustable iris 41 is in the closed state, the size of the light port 414 is the smallest, and the door and window is in the locked state. Figure 1 When the adjustable diaphragm 41 is opened, the adjustable diaphragm 41 presents a light opening 414, and the size of the light opening 414 can increase as the handle is rotated, and the doors and windows are in an openable state, such as Figure 2 shown.

[0034] The opening and closing indicator handle includes a handle 10, a handle head 20, a base assembly 30 and an opening and closing indicator assembly 40. The handle 10 is connected to one end of the handle head 20 and is integrally formed with the handle head 20. The base assembly 30 is connected to one end of the handle head 20 and is used to install the handle on the door and window. The opening and closing indicator assembly 40 is embedded in the handle head 20. It can be understood that the handle head 20 can rotate relative to the base assembly 30.

[0035] The handle head 20 is provided with a cavity 21 . One end of the handle head 20 is open, and the other end is provided with a perspective hole 22 communicating with the cavity 21 . A first limiting groove 23 is provided in the cavity 21 .

[0036] The opening and closing indication assembly 40 includes an adjustable iris 41, which includes an iris seat 411, an iris cover 412 and an iris piece 413. The iris cover 412 is rotatably disposed in the iris seat 411. A plurality of iris pieces 413 are provided, which are disposed between the iris cover 412 and the iris seat 411 and connected to the iris cover 412, so that an optical port 414 can be formed and the size of the optical port 414 can be adjusted by rotating with the iris cover 412. The iris seat 411 is embedded in the cavity 21 and fixed relative to the handle head 20, so that the optical port 414 is located directly below the perspective hole 22 along the axial direction of the handle head 20.
