[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] This utility model embodiment provides a locking assembly, such as Figure 1 , Figure 2 and Figure 7 As shown, the lock base 1 has a locking groove 111, and the lock buckle 2 has a locking plug 21, which is inserted into the locking groove 111; wherein, at least one of the locking groove 111 and the locking plug 21 has a first inclined surface 25.

[0034] The latch 2 assembly of this utility model has a locking groove 111 on the lock base 1 and a locking plug 21 on the latch 2. The locking plug 21 is inserted into the locking groove 111 to achieve locking. In use, the inclination of the first inclined surface 25 ensures that the locking plug 21 is tightly fastened in the locking groove 111 after being inserted, ensuring stable locking and preventing loosening. This provides high reliability and avoids the problems of easy loosening of the screw adjustment lock base 1, easy breakage of the screw, and poor reliability.

[0035] Specifically, the lock base 1 is provided with a locking boss 11, and a locking groove 111 is formed on the locking boss 11. Limiting flanges 112 protrude from both sides of the locking groove 111. The locking insert 21 is provided with insertion flanges 211 protruding from both sides. A first inclined surface 25 is provided on at least one of the insertion flanges 211 and the limiting flanges 112. The locking boss 11 is provided on the lock base 1, and a locking insert 21 is provided on the latch 2 corresponding to the locking boss 11. Simultaneously, the locking boss 11 has a locking groove 111, and limiting flanges 112 protrude from both sides of the locking groove 111. The locking insert 21 is provided with insertion flanges 211 protruding from both sides. When the latch 2 or the lock base 1 slides, the locking insert 21 is inserted into the locking groove 111, and the insertion flanges 211 are located in the locking groove 111 and abut against the limiting flanges 112. The locking plug 21 is inserted into the locking slot 111, and the locking assembly is locked by the blocking effect formed by the insertion protrusion 211 and the limiting protrusion 112. The connection contact area is large, and the insertion protrusion 211 and the limiting protrusion 112 are fastened together by the first inclined surface 25, making the locking more secure. At the same time, the locking plug 21 is less likely to have edge collision problems when inserted into the locking slot 111, resulting in a better locking experience.

[0036] More specifically, the first inclined surface 25 is an inclined surface provided on the side where the insertion protrusion 211 and the limiting protrusion 112 abut against each other, and the height of the first inclined surface gradually decreases in the direction in which the locking plug 21 is inserted into the locking groove 111; and / or the first inclined surface 25 is an inclined surface provided on the side where the limiting protrusion 112 and the insertion protrusion 211 abut against each other, and the height of the first inclined surface 25 gradually increases in the direction in which the locking plug 21 is inserted into the locking groove 111.

[0037] The locking groove 111 has a first opening 1111 at one end, and the locking plug 21 is inserted into the locking groove 111 through the first opening 1111. Specifically, the latch assembly of this utility model can be applied to sliding doors or sliding windows. Exemplarily, in one embodiment, the lock seat 1 is installed on the side of the sliding door track frame, and the latch 2 is slidably installed on the side of the sliding door. When the user pushes the sliding door to abut against the track frame, the latch 2 is pushed downward, and the locking plug 21 is inserted into the locking groove 111 through the first opening 1111. The insertion protrusion 211 and the limiting protrusion 112 form a stop, thereby locking the sliding door. When unlocking, the latch 2 is pushed upward, and the locking plug 21 disengages from the locking groove 111 through the first opening 1111, thereby unlocking the sliding door.

[0038] The sliding insertion method from the first opening 1111 makes it less likely to have edge collision issues, resulting in a better locking experience.

[0039] Specifically, in one embodiment, the lock seat 1 can be fixedly installed on the side of the track frame by screws or other fasteners, and the latch 2 can be slidably installed on the side of the sliding door. The latch can be installed in a specific way known to those skilled in the art, which will not be described in detail here.

[0040] Specifically, regarding the specific arrangement of the first inclined surface 25, in one embodiment, as follows: Figure 2 and Figure 3 As shown, the first inclined surface 25 is an inclined surface provided on the side where the insertion protrusion 211 abuts against the limiting protrusion 112. In the direction in which the locking plug 21 is inserted into the locking groove 111, the height of the first inclined surface 25 gradually decreases; and / or, as... Figure 4 As shown, the first inclined surface 25 is an inclined surface provided on the side where the limiting protrusion 112 and the insertion protrusion 211 abut. The height of the first inclined surface 25 gradually increases in the direction in which the locking plug 21 is inserted into the locking groove 111. In this embodiment, by setting a first inclined surface 25 whose height gradually decreases in the direction in which the locking plug 21 is inserted into the locking groove 111, and / or setting a first inclined surface 25 whose height gradually increases in the direction in which the locking plug 21 is inserted into the locking groove 111, the insertion protrusion 211 will gradually tighten towards the limiting protrusion 112 during insertion, making the connection between the latch 2 and the lock seat 1 more secure after locking, resulting in a more reliable lock that is less prone to loosening or shaking. Similarly, under the action of the first inclined surface 25, the limiting protrusion 112 will also tighten towards the insertion protrusion 211. Specifically, in this embodiment, the first inclined surface 25 can be provided only on the insertion protrusion 211, or only on the limiting protrusion 112, or the first inclined surface 25 can be provided on both the insertion protrusion 211 and the limiting protrusion 112.

[0041] Regarding the specific configuration of the first inclined plane 25, in another embodiment, such as Figures 5 to 7As shown, the locking groove 111 has an inclined rib 113 at the end away from the first opening 1111, and the first inclined surface 25 is the inclined surface on the inclined rib 113 facing the bottom of the locking groove 111; the height of the first inclined surface 25 gradually increases in the direction in which the locking plug 21 is inserted into the locking groove 111; and / or, the first inclined surface 25 is an inclined surface provided on the end of the locking plug 21 inserted into the locking groove 111, the first inclined surface 25 facing the first surface 24 on the latch 2 opposite to the lock seat 1, and the height of the first inclined surface 25 gradually increases in the direction in which the locking plug 21 is inserted into the locking groove 111. The setting of the first inclined surface 25 can push the locking plug 21 and the locking boss 11 to fasten each other during the insertion of the locking plug 21, thereby improving the locking firmness between the locking plug 21 and the locking boss 11.

[0042] Furthermore, the lock seat 1 is also provided with a limiting boss 12, and the limiting boss 12 has a limiting groove 121 with a second opening 1211 at one end. The second opening 1211 opens in the same direction as the first opening 1111. A limiting post structure 23 is installed on the latch 2 corresponding to the limiting groove 121. When the latch 2 is engaged with the lock seat 1, the limiting post structure 23 is located in the limiting groove 121. The limiting post structure 23 is used to abut against the limiting groove 121 to achieve limiting when there is a large misalignment between the lock seat 1 and the latch 2. The limiting post structure 23 only plays a limiting role when there is a large misalignment between the lock seat 1 and the latch 2. Specifically, the limiting post structure 23 includes a screw 231 and a threaded cylinder 232 formed on the lock seat 1. The inner side wall of the threaded cylinder 232 is provided with threads, and the screw 231 is threadedly installed in the threaded cylinder 232. In this way, the height of the limiting post structure 23 can be adjusted by rotating the screw 231, thereby adjusting the fit between the limiting post structure 23 and the limiting groove 121 as needed.

[0043] Specifically, the limiting boss 12 is located at one end of the lock seat 1, and the locking boss 11 is located at the other end of the lock seat 1, with the limiting boss 12 and the locking boss 11 spaced apart.

[0044] Both sides of the latch 2 have a first positioning edge 22 protruding to facilitate the positioning and installation of the latch 2. One side of the lock base 1 also has a second positioning edge 13 protruding to facilitate the positioning and installation of the lock base 1.

[0045] This utility model also discloses a sliding door, including the aforementioned latch assembly. Specifically, the lock base 1 is installed on the side of the sliding door track frame, and the latch 2 is slidably installed on the side of the sliding door. When the user pushes the sliding door to abut against the track frame, the latch 2 is pushed downward, and the locking insert 21 is inserted into the locking groove 111 through the first opening 1111. The insertion protrusion 211 and the limiting protrusion 112 form a stop, thereby locking the sliding door. When unlocking, the latch 2 is pushed upward, and the locking insert 21 disengages from the locking groove 111 through the first opening 1111, thereby unlocking the sliding door.

[0046] Specifically, in one embodiment, the lock seat 1 can be fixedly installed on the side of the track frame by screws or other fasteners, and the latch 2 can be slidably installed on the side of the sliding door. The latch can be installed in a specific way known to those skilled in the art, which will not be described in detail here.
