[0045] Refer to the following Figures 1 to 9 The invention introduces the lock and the door and window provided by the invention.

[0046] Please refer to Figure 1 and Figure 2 The present embodiment provides a door, which includes a door frame, a fan body 100 and a lock in the present embodiment, wherein the fan body 100 is mounted on the door frame and the lock is provided on the fan body 100. The lock can be used to lock and open the fan body 100 and the door frame.

[0047] Furthermore, the present embodiment further provides a window, which comprises a window frame, a fan 100 and a lock in the present embodiment, wherein the fan 100 is mounted on the window frame and the lock is provided on the fan 100. The lock can be used to lock and unlock the fan 100 and the window frame.

[0048] Specifically, the fan body 100 in the aforementioned door and window comprises a base material 110 and a fan profile 120. The fan profile 120 is connected to the base material 110, specifically to either side of the base material 110 along the X-direction, to form the fan body 100. The lock body 10 of the lock is connected to the base material 110 and inserted into the fan profile 120. The handle mechanism 20 of the lock is fixedly connected to the base material 110 to achieve the installation of the lock and the fan body 100.

[0049] Optionally, a mounting through hole 111 is provided on the substrate 110 , and the mounting through hole 111 is used for mounting the lock body 10 in the lock.

[0050] Optionally, a penetration hole 121 is formed on the fan profile 120, and the penetration hole 121 is used to penetrate the lock body 10 in the lock to achieve locking and loosening of the lock body 10 and the lock buckle on the door frame or window frame.

[0051] In addition, the fan profile 120 is provided with a first connecting surface 122, and the second connecting surface 123 is the first side of the fan body 100, which is used to abut against the lock body 10 in the lock to limit the lock body 10 and ensure the stability of the installation of the lock body 10.

[0052] Furthermore, the fan profile 120 is provided with a second connecting surface 123 , which is arranged opposite to the first connecting surface 122 along the X direction. The second connecting surface 123 is used to abut against the lock to improve the stability of the lock installation.

[0053] In the prior art, due to changes in the thickness of the fan profile 120 and changes in the distance between the first connecting surface 122 and the second connecting surface 123, the installation position of the lock body 10 and the fan profile 120 needs to be changed, which causes other structures inside the lock to also need to be changed, resulting in poor adaptability of the lock and low installation stability.

[0054] In order to solve the above problems, this embodiment provides a lock that can adapt to the installation of fan profiles 120 of different thicknesses, improve installation adaptability, and is convenient to install, highly efficient, and highly stable.

[0055] Please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5Specifically, the lock includes a lock body 10 and a handle mechanism 20, wherein the lock body 10 is inserted into the fan body 100, and the lock body 10 is provided with a first mounting surface 101 in contact with the first side of the fan body 100, that is, the first mounting surface 101 in contact with the first connecting surface 122 of the fan profile 120, and the first mounting surface 101 is in contact with the first connecting surface 122 of the fan profile 120 to achieve limited installation of the two; the handle mechanism 20 is transmission-connected to the lock body 10 to realize the driving of the lock body 10 by the handle mechanism 20, thereby realizing the locking and opening of the lock.

[0056] Specifically, the handle mechanism 20 includes a handle assembly 21 and a fixed installation assembly 22. The handle assembly 21 is transmission-connected to the lock body 10, and the fixed installation assembly 22 is connected to the handle assembly 21. The fixed installation assembly 22 is used to install the handle assembly 21 on the base material 110 of the fan body 100; through the setting of the fixed installation assembly 22, the fixed installation of the lock body 10 and the handle assembly 21 is achieved.

[0057] Among them, the fixed installation component 22 is provided with a second installation surface 2221 that contacts the second side of the fan body 100, that is, the second installation surface 2221 that contacts the second connecting surface 123 of the fan profile 120. The second installation surface 2221 contacts the fan profile 120 to realize the abutment between the fixed installation component 22 and the fan profile 120, thereby enhancing the position fixation between the lock and the fan profile 120, and improving the stability of the installation of the lock body 10.

[0058] Furthermore, the handle mechanism 20 includes an adjustment assembly 23 connected to the fixed mounting assembly 22. The adjustment assembly 23 is configured to adjust the distance between the second mounting surface 2221 and the first mounting surface 101. Specifically, the distance between the second mounting surface 2221 and the first mounting surface 101 can be adjusted according to the thickness of the fan profile 120, thereby making the lock adaptable to fan profiles 120 of different thicknesses, improving installation adaptability, and enhancing installation convenience, efficiency, and stability.

[0059] The lock in this embodiment utilizes a fixed mounting assembly 22 to securely mount the lock body 10 and handle mechanism 20 to the fan body 100. This creates a first mounting surface 101 and a second mounting surface 2221 that abut the first and second sides of the fan body 100, respectively, thereby enhancing the installation stability between the lock and the fan body 100. Furthermore, by adding an adjustment assembly 23 to adjust the distance between the second mounting surface 2221 and the first mounting surface 101, the lock can be installed on fan profiles 120 with varying fan body thicknesses without requiring structural replacement. This improves the lock's adaptability and provides convenient, efficient, and stable installation.

By separately setting the fixed seat body 221 and the base 222, not only can the handle assembly 21 and the lock body 10 be fixedly connected by the fixed seat body 221, but the base 222 can also abut against the substrate 110 to further fix the lock to the substrate 110. At the same time, the abutment of the second mounting surface 2221 of the base 222 and the fan profile 120 can further limit the lock, so that in the X direction, it is not only fixed by the abutment between the lock body 10 and the fan profile 120, but also fixed by the abutment between the base 222 and the fan profile 120, thereby further improving the installation stability of the lock.

[0061] Please refer to Figures 3 to 6 Specifically, the base 222 includes a first base 2222 and a second base 2223. The first base 2222 and the second base 2223 are respectively abutted against both sides of the lock body 10. Specifically, the first base 2222 and the second base 2223 are respectively abutted against both sides of the lock body 10 along the Y direction to achieve clamping and fixation between the base 222 and the substrate 110.

[0062] In addition, the fixed seat body 221 includes a first fixed seat 2211 and a second fixed seat 2212, and the first fixed seat 2211 and the second fixed seat 2212 are respectively abutted against the first base 2222 and the second base 2223.
