[0001] The utility model belongs to the technical field of accessories for flat-opening doors and windows, and particularly relates to a lock for flat-opening doors and windows. Background Technique
[0002] At present, the lock body of a flat-opening door or window usually consists of a lock tongue, a handle for controlling the lock tongue, and an anti-lock point. The handle is used to control the telescopic movement of the lock tongue, so as to cooperate with the lock box on the outer frame to achieve opening and closing. However, the current handles all use torsion springs to help return to the original position. After long-term use, the torsion springs are prone to loosening, especially the loosening caused by the long-term weight pressure of the handle on the torsion springs, resulting in the loss of the traction force on the handle. Due to gravity, the handle cannot return to the original position when it swings downward, affecting the appearance and possibly causing accidental unlocking. For this reason, we propose a lock for flat-opening doors and windows. Content of the Utility Model
[0003] The purpose of the utility model is to provide a lock for flat-opening doors and windows to solve the problem that the current handles all use torsion springs to help return to the original position, which is prone to loosening after long-term use and affects the use, as mentioned in the above background technique.

The inner side of the connecting shell 3 is provided with a base 6. One end of the base 6 is provided with a first gear ring 7. The inner side of the connecting shell 3 is provided with a fixing plate 8. One end of the fixing plate 8 is provided with a second gear ring 9. The inner side of the base 6 is provided with a connecting rod 10. One end of the connecting rod 10 is provided with a grip 11. One side of the grip 11 is provided with an insertion plate 12. One side of the insertion plate 12 is provided with a pulley 13. The surface of the second mounting member 14 is provided with a second fixing hole 15. One side of the second mounting member 14 is provided with a limiting block 16. One side of the limiting block 16 is provided with a limiting hole 17.
[0018] Specifically, both the upper and lower ends of one side of the first mounting member 1 are provided with first fixing holes 2. One side of the first mounting member 1 is fixedly installed with a connecting shell 3. The inner side surface of one side of the connecting shell 3 is fixedly installed with a connecting plate 4. One side of the connecting plate 4 is fixedly connected with a spring 5. One end of the base 6 is fixedly connected with one end of the spring 5. The other end of the base 6 is fixedly installed with a first gear ring 7. The inner side of the other side of the connecting shell 3 is fixedly installed with a fixing plate 8. One end of the fixing plate 8 is fixedly installed with a second gear ring 9. The first gear ring 7 and the second gear ring 9 are meshed. One side of the inner side of the base 6 is fixedly connected with one end of the connecting rod 10. One side of the connecting rod 10 is rotatably penetrated through the surface of the fixing plate 8. The other end of the connecting rod 10 extends to the outside of the connecting shell 3. The connecting rod 10 is rotatably penetrated through the surface of the connecting shell 3. One end of the connecting rod 10 is fixedly connected with a grip 11. One side of the grip 11 is fixedly connected with an insertion plate 12. The surface of one side of the insertion plate 12 is embedded and rotatably connected with a pulley 13. Both the upper and lower ends of the surface of the second mounting member 14 are provided with second fixing holes 15. One side of the second mounting member 14 is fixedly installed with a limiting block 16. One side of the limiting block 16 is fixedly provided with a limiting hole 17.
[0019] In this embodiment, the device can be respectively installed between the first mounting member 1 and the second mounting member 14 and the fixed frame of the casement window. When it is necessary to close the doors and windows, the doors and windows are driven to close by the grip 11. According to Figure 3As shown in the figure, when pressure is applied to the grip 11 in the direction of the connecting housing 3, the grip 11 will drive the base 6 to move through the connecting rod 10, and compress the spring 5 inside the connecting housing 3. While the base 6 moves towards the spring 5, it will drive the separation between the first gear ring 7 and the second gear ring 9 at the end. At this time, rotate the grip 11, so that the grip 11 drives the plug 12 on one side to rotate and insert into the limiting hole 17. Through the provided pulley 13, both side surfaces of the pulley 13 are in contact with the inner wall of the limiting hole 17. The rotating pulley 13 reduces the friction between the plug 12 and the limiting hole 17, facilitating long-term use. Finally, release the pressure applied to the grip 11, and the spring 5 will drive components such as the base 6 to reset, so that the first gear ring 7 and the second gear ring 9 at one end of the base 6 continue to complete the meshing connection, thereby restricting the movement of the grip 11. By clamping the plug 12 inside the limiting hole 17, the closing and fixing of the casement window can be realized. When opening the doors and windows, it is the same as above.
[0020] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
