[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Figures 1-7 This is a specific embodiment of the present invention, which is a quick-installation automatic locking single-sided latch. The shaft 3 is inserted into the outer frame 5, and the shaft 3 and the outer frame 5 are fixed by riveting. The movable block 1, steel ball 11, and first spring 2 are then inserted into the outer frame 5. After the first spring 2 contacts the shaft 3, the side of the outer frame 5 is fixed by pressing and bulging. The internal hexagonal fastening screw 13 is screwed into the moving block 8 through a threaded connection, and then cooperates with the plastic inner frame 7. The plastic inner frame 7 and the decorative cover 12 are connected by plastic clips on the decorative cover. The assembly of the moving block 8, internal hexagonal fastening screw 13, decorative cover 12, and plastic inner frame 7 is inserted into the outer frame 5 until the moving block 8 contacts the shaft 3. Then, the second spring 6 is inserted into the outer frame 5 through cooperation with the positioning post on the fixing block 4. The second spring 6 contacts the positioning post on the plastic inner frame 7, and the tail of the outer frame 5 is fixed to the fixing block 4 by pressing and bulging.

[0028] First, mill the mounting holes according to the shape of the latch on the sliding door and window profile. Assemble the latch and the lock hook and place them on the mounting holes of the profile. At this time, the latch cannot be completely inserted into the mounting hole. It is necessary to lock the movable block 1 at the end of the latch with the profile, and then push it towards the end of the latch. Then insert the tail of the latch. At this time, the latch will be fixed on the profile by the elastic force of the first spring 2. Then install the lock seat 10 on the frame of the sliding profile. By pushing the plastic inner frame 7 towards the tail of the latch, the decorative cover 12 is opened. Loosen the internal hexagon fastening screw 13 to adjust the extension length of the lock hook 9 to a suitable position. Tighten the internal hexagon fastening screw 13 to fix the lock hook 9. After the sliding sash contacts the frame, release it to achieve automatic locking.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
