[0037] Example

[0038] In this embodiment, the front side refers to the side with the handle, while the back side refers to the side away from the handle. This is only for the sake of explanation and is not intended to limit the scope of the invention.

[0039] See Figures 1 to 5 As shown, a door and window lock includes a lock housing 1, with a vertical strip groove 2 on the upper part of the lock housing. The lock housing is a conventional structure of the prior art, and is only applied in a simple way, so it is not described in detail. A lock body 3 is provided inside the lock housing. A handle 4 is provided on the front of the lock housing, and a protrusion 5 is provided on the top of the handle. The protrusion passes through the vertical strip groove and is rotatably connected to the lock body by a pin 6. In this embodiment, the height of the protrusion is less than the length of the vertical strip groove, that is, the protrusion can move up and down within the vertical strip groove after rotation, thereby ensuring the lifting and lowering of the lock body.

[0040] In practical applications, a locking plate 7 is provided on the back of the lock body. The locking plate is connected to the lock body, and the lock body moves up and down within the lock housing, causing the locking plate to rotate 90 degrees, so that the locking plate coincides with the lock housing to unlock, or the locking plate is perpendicular to the lock housing to lock. The locking plate is a stainless steel plate, and the length of the locking plate is greater than the width of the lock body. This is common technical knowledge in the prior art and can ensure the effectiveness of the locking plate.

[0041] In this embodiment, to improve the synchronization effectiveness of the lock plate, a vertical groove 8 is provided in the middle of the lock body, and a plurality of toothed protrusions 9 are provided on one inner wall of the vertical groove; at the same time, a gear 10 is fixed on the upper side of the lock plate, the gear is located in the vertical groove and meshes with the toothed protrusions; when the lock body rises and falls, the toothed protrusions drive the gear to rotate. When the lock body rises and falls, it can drive the gear to rotate, that is, drive the lock plate to rotate to realize the locking or unlocking action.

[0042] In practical applications, a back plate 11 is fixed to the back of the lock housing with screws; the lock plate and gear are rotatably connected between the back plate and the back of the lock housing via a pin. The back plate is used to limit the movement of the lock plate without affecting its normal rotation, and it is also convenient to install inside door and window frames.

[0043] In practical applications, the lower part of the lock shell is provided with a keyhole 12; a rotating lock block 13 is provided inside the keyhole, and a locking protrusion 14 is provided on the inner side of the rotating lock block; a C-shaped lock groove 15 is provided on the lower part of the outer side of the lock body; in use, the rotating lock block rotates and the locking protrusion engages with the C-shaped lock groove to lock and position itself, at which time the lock body cannot be raised or lowered. Furthermore, the surface of the locking protrusion is a regular polygon, facilitating rotation using appropriate tools.

[0044] In this embodiment, the lower part of the lock shell is provided with a combination lock hole 16; a dial combination lock 17 is provided inside the combination lock hole; a through hole 18 is provided in the center of the dial combination lock, and a strip-shaped lock groove 19 is provided on the side wall of the through hole; a protruding rod 20 that mates with the through hole is integrally formed at the bottom end of the lock body, and a strip-shaped protrusion 21 is provided on the side wall of the protruding rod; when the lock body moves downward, the protruding rod extends into the through hole and the strip-shaped protrusion is located in the strip-shaped lock groove. In use, when the dial combination lock is locked, the strip-shaped protrusion of the protruding rod is misaligned with the strip-shaped lock groove of the through hole. At this time, the protrusion cannot move downward into the dial combination lock, and the lock body cannot move downward, ensuring the locking effectiveness and stability of the lock plate.

[0045] The handle has a locking cavity on its back; when the handle is folded onto the lock housing, the side of the lock housing engages and is positioned within the locking cavity. This structure ensures that the handle and the surface of the lock housing are aligned when the handle is folded, enhancing its aesthetic appeal.

[0046] This utility model also provides a sliding door and window, including the aforementioned door and window lock.

[0047] This utility model has the following advantages: Its structure is rationally designed. A vertical slot is provided on the upper part of the lock housing, and the handle's protrusion passes through this slot and is rotatably connected to the lock body via a pin. In use, the handle rotates around the pin to fold onto the surface of the lock housing, and the lock body rotates the lock plate to open, thus achieving the locking operation. When the handle is open around the pin, it can be held and moved downwards, causing the lock plate to rotate and fold onto the back of the lock housing, thus achieving the unlocking operation. It not only has fewer structural components but is also convenient to operate, improving stability and reliability, and has strong applicability.

[0048] Furthermore, a vertical groove is provided in the middle of the lock body, and several toothed protrusions are provided on one inner wall of the vertical groove; the gear of the lock plate meshes with the toothed protrusions, so that the lock plate can be simultaneously unlocked or unlocked when the lock body is raised and lowered, thereby improving the stability and smoothness of the lock plate movement.

[0049] Furthermore, it is equipped with a rotating lock block and a dial combination lock, which can realize the locking operation. After locking, it can prevent the lock body from moving downward, ensuring the locking effectiveness and reliability of the lock plate.
