[0028] See Figures 1 to 7 This utility model relates to a sliding door and window and its locking assembly 100. The sliding door and window includes a sliding door and window body 300 and a fixed frame 200 (door frame or window frame). During the locking process, the locking assembly 100 can drive the sash of the door and window to move laterally, thereby causing the light-resistant rubber strip 330 on the door and window to press against the door frame or window frame, and the hook-resistant rubber strips 340 on adjacent doors and windows to press against each other, thereby achieving the sealing of the sliding door and window and improving the problem of air leakage and water seepage in the sliding door and window.
[0029] It is understood that the sliding doors and windows of this utility model refer to doors and windows that can be pushed and pulled, specifically sliding doors or sliding windows. The number of door leaves of the sliding door or window leaves of the sliding window is two or more. The sliding door and window body 300 (door leaf or window leaf) includes a sash plate and a light bracket 310 and a hook bracket 320 respectively disposed on both sides of the width direction of the sash plate. The light bracket 310 and the hook bracket 320 are each provided with a sealing strip, namely the light bracket sealing strip 330 and the hook bracket sealing strip 340.
[0030] The lock assembly 100 includes a latch 10 and a hook 20 that are connected to each other. The latch 10 is used to be installed on the fixed frame 200, and the hook 20 is used to be installed on the sliding door and window body 300.
[0031] The latch 10 includes a latch plate 11, the middle of which extends away from the latch hook 20 to form a locking cavity 110. The locking cavity 110 has openings at both ends, and a locking shaft 12 is provided at one end of the locking cavity 110 along the height direction. The latch hook 20 includes a latch hook plate 22 and a hook body 21 integrally formed with the latch hook plate 22. The hook body 21 extends and is bent along the direction close to the latch plate 11. The hook body 21 and the locking shaft 12 are configured such that the hook body 21 can move laterally across the locking shaft 12, and the locking shaft 12 is engaged at the position where the hook body 21 meets the latch hook plate 22.
[0032] In another embodiment, the latch 10 is installed on the sliding door body and the lock hook 20 is installed on the fixed frame 200, which can also achieve the purpose of this utility model.
[0033] In the lock assembly 100 of this utility model, the hook body 21 of the lock hook 20 moves laterally and generates a displacement in the height direction relative to the locking shaft 12 of the latch 10, thereby engaging the locking shaft 12 at the part where the hook body 21 of the lock hook 20 meets the lock hook plate 22. During the process of locking the lock hook 20 and the latch 10, the sliding door and window body 300 is driven to move laterally, so that the smooth rubber strip 330 on the sliding door and window body 300 abuts against the fixed frame 200, and the hook rubber strips 340 between adjacent sliding door and window bodies 300 abut against each other, thereby achieving the sealing of the sliding door and window and improving the problem of air leakage and rain seepage in the sliding door and window.
[0034] In one embodiment, the hook body 21 includes a horizontal portion and an inclined portion. The horizontal portion is connected to the locking hook plate 22, and the inclined portion is connected to the end of the horizontal portion away from the locking hook plate 22, and at least the side of the inclined portion facing the locking hook plate 22 is set as an inclined surface. The hook body 21 is configured to cooperate with the locking shaft 12 through the inclined surface to facilitate the locking of the locking hook 20 and the locking buckle 10.
[0035] In this embodiment, the locking shaft 12 is disposed at the upper end of the locking cavity 110, and the inclined surface of the hook body 21 is inclined upward in a direction away from the locking hook plate 22. In another embodiment, the locking shaft 12 is disposed at the lower end of the locking cavity 110, and the locking hook 20 is inclined downward in a direction away from the locking hook plate 22.
[0036] In one embodiment, a bushing 13 is fitted onto the locking shaft 12. The bushing 13 is rotatable relative to the locking shaft 12 and abuts against the transverse portion when it is engaged with the locking hook 20. When the hook body 21 of the locking hook 20 enters the locking cavity 110, it abuts against the bushing 13 and moves laterally relative to the bushing 13. During the locking process, the bushing 13 rotates relative to the locking shaft 12, making the locking process of the locking hook 20 easier and improving the operating feel.
[0037] Optionally, the axial length of the bushing 13 is matched with the width of the locking cavity 110. In addition, the bushing 13 is preferably made of plastic (such as nylon) to avoid noise caused by metal-to-metal collision between the locking hook 20 and the locking buckle 10.
[0038] In one embodiment, on one side of the opposite sides of the locking cavity 110, there is a through hole and an internal threaded hole 111; one end of the locking shaft 12 is provided with an external thread that mates with the internal threaded hole 111 and is connected to the internal threaded hole 111 after the locking shaft 12 passes through the through hole.
[0039] In other embodiments, the locking shaft is welded to the locking cavity, or the locking shaft is riveted to the locking cavity.
[0040] In one embodiment, the two ends of the latch plate 11 are provided as mounting portions 113, and each mounting portion 113 has a countersunk hole for inserting a screw to fix it to the fixed frame 200 or the sliding door / window body 300. By providing countersunk holes on the mounting portions 113, the screw heads of the fixing screws can be hidden in the countersunk holes, which is both aesthetically pleasing and avoids the screw heads being exposed, thus preventing gaps between the latch plate 11 and the latch plate 22 and improving the locking effect.
[0041] In one embodiment, one of the countersunk holes is an adjustment hole 112, which is an oblong hole. By setting one of the countersunk holes as the adjustment hole 112, when the latch plate 11 is installed on the fixed frame 200, a screw can be first passed through the adjustment hole 112 to connect to the fixed frame 200, and then another screw can be passed through the other countersunk hole to connect to the fixed frame 200. During the installation of the latch plate 11, the adjustment hole 112 can achieve positioning and fine adjustment, which facilitates the installation of the latch plate 11.
[0042] In one embodiment, the hook plate 22 has a locking post 23 on the side facing away from the hook body 21. The locking post 23 is used to insert into the insertion hole of the drive bar in the sliding door / window. Installing the hook 20 by insertion can speed up the assembly of the hook 20 with the sliding door / window.
[0043] In one embodiment, the locking pins 23 are provided in pairs and are respectively located at both ends of the locking hook plate 22.
[0044] In one embodiment, the hook plate 22 has a locking block 24 on the side facing away from the hook body 21. The locking block 24 protrudes from both sides of the hook plate 22 in the width direction and is used to engage with a preset groove on the sliding door / window body 300, preventing the hook 20 from moving along the thickness direction of the hook plate 22 and separating from the sliding door / window body 300. It is understood that when the hook 20 is mounted on the fixed frame 200, the locking block is installed in a preset groove on the fixed frame 200.
