[0002] The mortise and tenon self-locking window keel is a keel manufactured using the traditional mortise and tenon structural principle. Its characteristic is that it has a self-locking function and can automatically lock after assembly without the need for additional tools or fasteners. This structural design not only improves the convenience of assembly, but also increases the stability of the structure. Different windows may require keels of different lengths to adapt to their size and installation requirements.

[0003] The method of using the traditional mortise and tenon self-locking window keel mainly includes the steps of design preparation, material preparation, mortise and tenon processing, connection assembly, fixing and adjustment, installation of other components, inspection and testing, and maintenance and care. First, design a suitable mortise and tenon structure according to the size and installation requirements of the window, and determine the length and connection method of the keel. Then, select the appropriate wood or metal material and process it according to the design requirements. Next, match the processed tenon and mortise with each other so that the tenon can be smoothly inserted into the mortise. During the assembly process, the contact surface of the tenon and mortise will automatically lock to form a stable connection. After completing the installation of the window, check the firmness and stability of the connection and perform necessary tests. Finally, regularly check the mortise and tenon connection parts to ensure that there is no looseness or damage, and perform proper maintenance and care.

[0027] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a mortise and tenon self-locking window keel, comprising a transverse keel 1, a transverse keel 2 2 is slidably connected inside the transverse keel 1, vertical keels 3 are arranged at both ends of the transverse keel 2, a clamping assembly is arranged inside the transverse keel 1, a fixing rod 5 is fixedly connected inside the transverse keel 2, a spring sheet 6 is arranged on the outer wall of the fixing rod 5, a fixing block 7 is fixedly connected to the outer wall of the spring sheet 6, a fixing shaft 8 is fixedly connected to one side of the outer wall of the fixing block 7, the outer wall of the fixing shaft 8 is slidably connected to the inside of the transverse keel 1, a rack 10 is fixedly connected to the other side of the outer wall of the fixing block 7, a gear 9 is rotatably connected to the lower surface of the fixing rod 5, the gear 9 is meshed with the rack 10, and the clamping assembly comprises a through hole 4, and the through hole 4 is opened inside the transverse keel 1;

[0028] Specifically, it is first necessary to operate the fixed shaft 8 to make it slide inside the through hole 4. This action will drive the rack 10 to move through the action of the fixed block 7. The meshing connection relationship between the rack 10 and the gear 9 makes the gear 9 rotate with the movement of the rack 10, causing the fixed shaft 8 on the other side to move synchronously, thereby realizing the coordinated action of the two fixed shafts 8. As the two fixed shafts 8 move, the spring sheet 6 begins to contract and generates a thrust. The thrust pushes the fixed shaft 8 to slide on the inner wall of the horizontal keel 1 until the fixed shaft 8 is pushed to the inside of the preset through hole 4 inside the horizontal keel 1, thereby achieving fixation, thereby allowing the keel to be adjusted in length to meet the installation requirements of windows of different sizes.

[0029] Reference Figure 1 , Figure 4 and Figure 5One end of the transverse keel 1 is fixedly connected with a fixing plate 11, the outer wall of the fixing plate 11 is slidably connected to the inner wall of the vertical keel 3, the inner wall of the fixing plate 11 is fixedly connected with a reinforcing plate 14, the inner wall of the fixing plate 11 is fixedly connected with a reinforcing plate 2 18, the reinforcing plate 14 and the reinforcing plate 2 18 are staggered, the outer wall of the fixing plate 11 is fixedly connected with a mortise 12, the outer wall of the fixing plate 11 is fixedly connected with a mortise 2 13, the interior of the vertical keel 3 is provided with a mortise 15, the outer walls of the mortise 12 and the mortise 2 13 are slidably connected to the interior of the mortise 15, the outer walls of the transverse keel 1, the fixing plate 11 and the vertical keel 3 are all coated with a solvent-based paint coating 16, and the interiors of the transverse keel 1, the fixing plate 11 and the vertical keel 3 are fixedly connected with a stainless steel inner plate 17;

[0030] Specifically, firstly, it is necessary to align the mortise 12 and the mortise 13 on the outer wall of the fixing plate 11 with the mortise 15, and then insert the mortise 12 and the mortise 13 into the mortise 15. Once the mortise 12 and the mortise 13 are fully inserted, a stable connection between the keels is achieved. In order to further enhance the strength of the connecting part, reinforcing plates 14 and 18 are alternately placed inside the fixing plate 11, which not only increases the stability of the structure, but also improves the overall load-bearing capacity. Finally, in order to ensure the durability and aesthetics of the keel, the outer walls of the transverse keel 1, the transverse keel 2 and the vertical keel 3 are evenly coated with a solvent-based paint coating 16, and a stainless steel inner plate 17 is used inside to further enhance the corrosion resistance and wear resistance of the keel.

[0031] When the mortise and tenon self-locking window keel is needed, first, the fixed shaft 8 is pressed to slide inside the through hole 4, thereby driving the rack 10 to move through the fixed block 7, and then through the meshing connection between the rack 10 and the gear 9, the gear 9 rotates with the movement of the rack 10, thereby driving the fixed shaft 8 on the other side to move synchronously, and then the movement of the two fixed shafts 8 drives the spring sheet 6 to contract, thereby pushing the fixed shaft 8 to slide on the inner wall of the horizontal keel 1, and then pushing the fixed shaft 8 to the inside of the preset through hole 4 inside the horizontal keel 1 for fixing, so as to achieve In order to adjust the length of the keel, the mortise 12 and the mortise 13 on the outer wall of the fixing plate 11 are aligned with the mortise 15 and inserted. When the mortise 12 and the mortise 13 are completely inserted into the mortise 15, the installation of the keels can be achieved. Then, the connecting part is strengthened by the reinforcing plates 14 and the reinforcing plates 18 staggered inside the fixing plate 11. Finally, the keel is strengthened by the solvent-based paint coating 16 evenly coated on the outer walls of the transverse keel 1, the transverse keel 2 and the vertical keel 3 and the internal stainless steel inner plate 17, thereby achieving a high-strength connection effect.
