Description

Technical Field

[0001] This utility model relates to the field of door and window lock technology, specifically to a door and window lock latch device that is easy to install and has a simple structure. Background Technology

[0002] Existing door and window locks mainly consist of a lock groove and a lock hook. The lock hook is hinged to the door or window sash, and the lock groove is installed on the door or window frame. As the door or window sash moves towards the frame, the lock hook, due to the structure of the lock groove or the hook itself, rotates around its hinge axis, passing over the lock groove, and then locks into place. While simple, this lock structure has low security. With some tools, the lock hook can be pushed upwards, causing it to rotate around its hinge axis and exit the lock groove. Alternatively, some lock hooks with a triangular cross-section engage with the lock groove under spring pressure. By using a tool to push the hook out of the lock groove, the lock hook and lock groove are no longer engaged, allowing the door or window to be opened. Furthermore, if there is any misalignment after installation, existing locks require disassembly and reinstallation, making them impractical. Utility Model Content

[0003] The technical problems to be solved by this utility model are poor security, inconvenience in adjustment after installation, and poor practicality.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a door and window latch device that is easy to install and has a simple structure, including a lock groove assembly and a lock cylinder assembly arranged opposite to each other. The lock cylinder assembly includes a mounting base, on which a core seat is provided. A lock cylinder body is retractably provided inside the core seat. An unlocking assembly is provided on the lock cylinder body. The end of the lock cylinder extends out of the core seat and has a lock hook at the end. The lock groove assembly includes a groove seat, in which a groove is provided in the middle to cooperate with the lock cylinder body. A guide groove and a limiting groove are provided opposite to each other on the groove. The guide groove and the limiting groove both cooperate with the lock hook and are arranged sequentially in the direction away from the lock cylinder assembly.

[0005] Furthermore, the core seat is provided with a connecting groove that mates with the lock cylinder body, and a spring is provided between the connecting groove and the lock cylinder body.

[0006] Furthermore, the unlocking component includes a through groove circumferentially located in the connecting groove, and a connecting rod on the lock cylinder body that mates with the through groove. The other end of the connecting rod passes through the through groove and has a ball end.

[0007] Furthermore, the through groove includes a horizontal groove and a vertical groove, and the angle between the horizontal groove and the vertical groove on the horizontal plane is 90°.

[0008] Furthermore, the mounting base is provided with a core cylinder, the core seat is slidably connected to the core cylinder, and an adjusting rod is rotatably provided on the core seat. The adjusting rod passes through the core cylinder through a thread and has a knob at its end.

[0009] Furthermore, the limiting groove is a fan-shaped structure with the lock cylinder as its axis.

[0010] Furthermore, the end face of the core seat is provided with a storage groove that cooperates with the locking hook.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1. The lock cylinder body and the groove are matched by the lock hook and the guide groove, which facilitates the insertion of the lock cylinder body and the lock hook into the groove seat. Then, the lock groove assembly and the lock cylinder assembly are matched by the matching of the limiting groove and the lock hook, thereby achieving stable locking between the door and window and the frame, reducing the possibility of traditional doors and windows being easily opened from the outside by some means, and improving the safety performance.

[0013] 2. The unlocking component allows for easy release of the limits between the lock cylinder component and the lock groove component, thus facilitating the opening of doors and windows.

[0014] 3. By adjusting the sliding arrangement of the core cylinder and core seat, as well as the distance between the core cylinder and the core seat, the distance between the core seat and the slot seat can be adjusted, thus improving practicality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 A door and window latching device that is easy to install and has a simple structure includes a lock groove assembly 1 and a lock cylinder assembly 2 arranged opposite to each other. The lock cylinder assembly 2 includes a mounting base 3, on which a core seat 4 is provided. A lock cylinder body 5 is retractably provided inside the core seat 4. A connecting groove 12 that mates with the lock cylinder body 5 is provided inside the core seat 4. A spring 13 is provided between the connecting groove 12 and the lock cylinder body 5. The end of the lock cylinder extends out of the core seat 4 and has a lock hook 7 at the end. The lock groove assembly 1 includes a groove seat 8. A groove 9 that mates with the lock cylinder body 5 is provided in the middle of the groove seat 8. A guide groove 10 and a limiting groove 11 are arranged opposite to each other on the groove 9. The guide groove 10 and the limiting groove 11 both mate with the lock hook 7 and are arranged sequentially in the direction away from the lock cylinder assembly 2. The limiting groove 11 is a fan-shaped structure with the lock cylinder body 5 as the axis. The end face of the core seat 4 has a receiving groove that mates with the lock hook.

[0024] Existing door and window locks mainly consist of a lock groove and a lock hook 7. The lock hook 7 is hinged to the door or window sash, and the lock groove is installed on the door or window frame. As the door or window sash moves towards the door or window frame, the lock hook 7, due to the characteristics of its structure, rotates around its hinge axis, passing over the lock groove. Then, under the action of gravity or a torsion spring hinge, it falls back, thus achieving a locking engagement between the lock hook and the lock groove. While these lock structures are simple, they offer relatively low security. A hinged lock hook can be driven by auxiliary tools to rotate in the opposite direction around the hinge point, allowing it to exit the lock groove.

[0025] Alternatively, some sliding latches have a triangular cross-section. The latch engages with the lock groove under the action of a spring. With the help of some auxiliary tools, it is moved to the inclined surface of the lock hook, which drives the lock hook to slide out of the lock groove. The lock hook and lock groove no longer engage, and the door and window can be opened. However, the security is poor.

[0026] The aforementioned simple door and window locks can be easily unlocked by prying or flicking with a tool, resulting in low security.

[0027] In this application, the lock cylinder body 5 is driven to move towards the slot seat 8 until the lock cylinder body 5 engages with the groove 9. At this time, the guide groove 10 engages with the lock hook 7. The lock cylinder body 5 drives the lock hook 7 to move along the guide groove 10 until it moves to the connection between the guide groove 10 and the limiting groove 11. Then, the lock cylinder body 5 drives the lock hook 7 to rotate, so that the lock hook 7 engages with the limiting groove 11 to achieve limiting. At this time, the spring 13 is stretched and stored, driving the lock cylinder body 5 to drive the lock hook 7 to stably abut against the end face of the limiting groove 11. The lock hook 7 has a straight structure.

[0028] At this point, the movement path of the lock cylinder body 5 is no longer a simple translation or hinge, making it difficult for ordinary tools to unlock it through the door gap, thereby improving the security performance of the device.

[0029] Combined with appendix Figure 6 The lock cylinder body 5 is provided with an unlocking component 6. The unlocking component 6 includes a through groove 14 circumferentially located in the connecting groove 12. The through groove 14 includes a horizontal groove 17 and a vertical groove 18. The angle between the horizontal groove 17 and the vertical groove 18 on the horizontal plane is 90°. The lock cylinder body 5 is provided with a connecting rod 15 that cooperates with the through groove 14. The other end of the connecting rod 15 passes through the through groove 14 and has a ball head 16 at the end.

[0030] When unlocking is required, by holding the ball head 16, the ball head 16 drives the connecting rod 15 to move along the vertical groove 18 to the connection point with the horizontal groove 17. The connecting rod 15 drives the lock cylinder body 5 to move the lock hook 7 from the limiting groove 11 to the connection point with the guide groove 10. Then, under the reset action of the spring 13, the lock cylinder body 5 drives the lock hook 7 and the connecting rod 15 to slide into the connecting groove 12, and the lock groove assembly 1 and the lock cylinder assembly 2 lose their limiting position.

[0031] The core seat 4 has a storage groove on the end face near the lock groove assembly 1 that cooperates with the lock hook 7. The lock hook 7 slides into the connecting groove 12 with the lock core body 5 under the reset action of the spring 13. The lock hook 7 is stored in the storage groove to prevent it from protruding from the core seat 4 and being easily damaged by collision.

[0032] Combined with appendix Figure 5 and attached Figure 6The mounting base 3 is provided with a core cylinder 19, and the core seat 4 is slidably connected to the core cylinder 19. An adjusting rod 20 is rotatably provided on the core seat 4. The adjusting rod 20 passes through the core cylinder 19 by a thread and has a knob at its end.

[0033] One end of the core tube 19 is open, and the core seat 4 is slidably disposed inside the core tube 19 and passes through the core tube 19.

[0034] When the mounting base 3 is aligned and installed, but there is a horizontal deviation in the position of the mounting base 3, the adjusting rod 20 can be rotated. The adjusting rod 20 drives the core seat 4 to move horizontally through the threaded engagement with the core cylinder 19, thereby adjusting the distance between the core seat 4 and the slot seat 8, avoiding the need for reassembly and reinstallation, and improving practicality.
