[0045] The following reference Figures 1 to 9 This invention introduces the locks and doors / windows provided by this utility model.

[0046] Please refer to Figure 1 and Figure 2 This embodiment provides a door, which includes a door frame, a door leaf 100, and a lock as described in this embodiment. The door leaf 100 is installed on the door frame, and the lock is disposed on the door leaf 100. The lock can be used to lock and open the door leaf 100 and the door frame.

[0047] Furthermore, this embodiment also provides a window, which includes a window frame, a sash 100, and a lock as described in this embodiment. The sash 100 is installed on the window frame, and the lock is disposed on the sash 100. The lock can be used to lock and open the sash 100 and the window frame.

[0048] Specifically, the sash 100 in the aforementioned door and window includes a base material 110 and a sash profile 120. The sash profile 120 is connected to the base material 110, specifically, the sash profile 120 is connected to either side of the base material 110 along the X direction to form the sash 100. The lock body 10 of the lock is connected to the base material 110 and inserted into the sash profile 120.

[0050] Optionally, the fan profile 120 is provided with a through hole 121 for inserting the lock body 10 in the lock to achieve locking and unlocking of the lock body 10 with the latch on the door frame or window frame.

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

[0052] Furthermore, the fan profile 120 is provided with a second connecting surface 123, which is arranged opposite to the first connecting surface 122 in 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 the change in the thickness of the fan profile 120 and the change in the distance between the first connecting surface 122 and the second connecting surface 123, the installation positions of the lock body 10 and the fan profile 120 need to be changed, which in turn requires changes to other internal structures of the lock, resulting in poor adaptability of the lock and low installation stability.

[0054] To address the aforementioned issues, this embodiment provides a lock that is adaptable to the installation of fan profiles 120 of different thicknesses, improving installation compatibility and offering convenient, efficient, and stable installation.

[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. The lock body 10 is inserted into the fan body 100. The lock body 10 has a first mounting surface 101 that contacts the first side of the fan body 100, that is, the first mounting surface 101 that contacts the first connecting surface 122 of the fan profile 120. The first mounting surface 101 contacts the first connecting surface 122 of the fan profile 120 to achieve the limiting installation of the two. The handle mechanism 20 is drivenly 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 unlocking of the lock.

[0056] Specifically, the handle mechanism 20 includes a handle assembly 21 and a fixed mounting assembly 22. The handle assembly 21 is connected to the lock body 10, and the fixed mounting assembly 22 is connected to the handle assembly 21. The fixed mounting assembly 22 is used to mount the handle assembly 21 to the base material 110 of the fan body 100. The fixed mounting assembly 22 is used to fix the lock body 10 and the handle assembly 21.

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

[0058] Furthermore, the handle mechanism 20 also includes an adjustment component 23, which is connected to the fixed mounting component 22. The adjustment component 23 is configured to adjust the distance between the second mounting surface 2221 and the first mounting surface 101. This allows the distance between the second mounting surface 2221 and the first mounting surface 101 to be adjusted according to the thickness of the fan-shaped profile 120, thereby enabling the lock to adapt to the installation of fan-shaped profiles 120 of different thicknesses, improving installation adaptability, convenience, efficiency, and stability.

[0059] In this embodiment, the lock body 10 and handle mechanism 20 are fixedly mounted on the fan body 100 using a fixed mounting assembly 22, forming a first mounting surface 101 and a second mounting surface 2221 that abut against the first and second sides of the fan body 100, respectively, thereby improving the installation stability between the lock and the fan body 100. Simultaneously, 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 of fan bodies 100 with different thicknesses without requiring structural replacement, improving the lock's installation adaptability and offering convenient, efficient, and stable installation.

[0060] Please refer to Figures 1 to 7In this embodiment, the fixed mounting assembly 22 includes a fixed base 221 and a base 222. The fixed base 221 is connected to the handle assembly 21 and is used to fix the handle assembly 21 to the lock body 10. The adjusting assembly 23 is rotatably connected to the fixed base 221. The base 222 is connected to the fixed base 221 and abuts against the base material 110 of the fan body 100. The second mounting surface 2221 is disposed on the base 222. The adjusting assembly 23 is throttle connected to the base 222. The adjusting assembly 23 can rotate and drive the base 222 to move, so as to adjust the distance between the second mounting surface 2221 and the first mounting surface 101. By separating the fixing body 221 and the base 222, not only can the handle assembly 21 and the lock body 10 be fixedly connected by the fixing body 221, but the base 222 can also abut against the base material 110 to further fix the lock to the base material 110. At the same time, the abutment between the second mounting surface 2221 of the base 222 and the fan-shaped material 120 can further limit the lock, so that in the X direction, not only the lock body 10 and the fan-shaped material 120 are abutted and fixed, but also the base 222 and the fan-shaped material 120 are abutted and fixed, which further improves 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 respectively abut against the two sides of the lock body 10. Specifically, the first base 2222 and the second base 2223 abut against the two sides of the lock body 10 along the Y direction to achieve clamping and fixing between the base 222 and the base material 110.

[0062] Furthermore, the fixing body 221 includes a first fixing seat 2211 and a second fixing seat 2212. The first fixing seat 2211 and the second fixing seat 2212 abut against the first base 2222 and the second base 2223 respectively. The first fixing seat 2211 and the second fixing seat 2212 are fixedly connected, which can realize the fixing between the fixing body 221 and the lock body 10, and at the same time, the fixing body 221 can lock the base 222, so that the base 222 abuts against the base material 110.

[0063] Please refer to Figure 4 , Figure 6 and Figure 8Furthermore, the adjustment assembly 23 includes two adjustment structures 231, which are respectively connected to the first fixed base 2211 and the second fixed base 2212. Each adjustment structure 231 includes an adjustment shaft 2311 and an adjustment cam 2312. One end of the adjustment shaft 2311 is rotatably connected to the first fixed base 2211, and the other end passes through the first base 2212 and is fixedly connected to the adjustment cam 2312; alternatively, one end of the adjustment shaft 2311 is rotatably connected to the second fixed base 2212, and the other end passes through the second fixed base 2212. The base 2223 is fixedly connected to the adjusting cam 2312; the adjusting cam 2312 is connected to the lock body 10, and the adjusting cam 2312 has a large end, a transition section and a small end. The base 222 has an adjusting hole 2224, and the outer peripheral surface of the adjusting cam 2312 can abut against the hole wall of the adjusting hole 2224 near the second mounting surface 2221; the adjusting shaft 2311 can rotate and drive the adjusting cam 2312 to rotate so that the large end, transition section or small end abuts against the hole wall of the adjusting hole 2224 near the second mounting surface 2221.

[0064] During adjustment, the position of the first base 2222 can be adjusted first, followed by the position of the second base 2223. Specifically, when adjusting the second mounting surface 2221 of the first base 2222, the adjustment shaft 2311 can be rotated according to the current installation position of the lock body 10, causing the adjustment cam 2312 to rotate, thereby bringing the second mounting surface 2221 and the corresponding second connecting surface 123 into contact. At this time, since the adjustment cam 2312 is still connected to the lock body 10, it drives the lock body 10 to move, causing the first mounting surface 101 and the corresponding first connecting surface 122 to abut, thus completing the adjustment of the first base 2222. Then, the second mounting surface 2221 at the second base 2223 can be adjusted to complete the position adjustment of the base 222 and the lock body 10 along the Y direction, so that the lock can be adapted to fan-shaped profiles 120 of different thicknesses.

[0065] Optionally, the adjusting cam 2312 and the adjusting shaft 2311 are fixedly connected by riveting, which is convenient to operate and secure. Of course, in other embodiments, the two can also be fixed by other methods such as welding or pinning, which are not specifically limited here.
