This plug-in connection method not only simplifies the installation process but also greatly improves the stability of the connection, ensuring that the door will not loosen or fall off during long-term use. The pivot seat 3 is precisely plugged into the socket 11 on the fitting 1 via the insert block 31, achieving a stable positioning of the pivot seat 3 on the fitting 1. This design ensures that the door maintains smooth and stable movement during opening and closing, improving the door's comfort and durability.

[0027] The installation of side panel 4 further enhances the structural strength of the door. Side panel 4 is tightly connected to the outer wall of pipe 1 by bolts and other fasteners, effectively resisting external impacts and pressures that the door may be subjected to during use, and ensuring the overall stability and safety of the door.

[0028] The entire structure is designed with aesthetics and a sense of space in mind. Through precise dimensional control and ingenious assembly, an extremely narrow frame design is achieved. This design not only enhances the overall aesthetics of the door but also makes it appear lighter and more transparent, making it particularly suitable for modern minimalist home décor.

[0029] In this embodiment, a support plate 14 is installed on the lower interior of the pipe fitting 1. This design enhances the overall structural strength of the pipe fitting 1 and provides a stable support surface for subsequent bolt fixing. The support plate 14 can disperse the stress generated during bolt tightening, preventing the pipe fitting 1 from deforming or breaking due to excessive local stress, thereby improving the stability and durability of the entire mortise and tenon structure.

[0030] Specifically, a first bolt 5 is installed on the inner side of the pipe fitting 1. The first bolt 5 locks and fixes the insert block 31, and the end of the first bolt 5 is pressed and fixed on the support plate 14. This design ensures a tight connection between the rotating shaft seat 3 and the pipe fitting 1, preventing the rotating shaft seat 3 from shaking or falling off during use. At the same time, through the dispersing effect of the support plate 14, the tightening force of the first bolt 5 is more uniform, improving the stability and reliability of the connection.

[0031] Furthermore, a second bolt 6 is installed inside the lower part of the pipe fitting 1. The second bolt 6 locks and fixes the connector 2 in place, and the end of the second bolt 6 is pressed and fixed onto the support plate 14. This design further enhances the connection strength between the connector 2 and the pipe fitting 1, preventing the connector 2 from loosening or falling off under stress. Through the tightening action of the second bolt 6, the connector 2 can stably withstand various forces during the opening and closing of the door, ensuring the stability and safety of the door.

[0032] Furthermore, the top wall surface of fitting 1 has a strip-shaped glass inlet 15, and the top center of fitting 2 has an inner groove 22. The bottom end of the glass is inserted through the glass inlet 15 and engages with the inner groove 22 of fitting 2. This design allows the glass to be easily installed in the door and forms a tight connection with the door. Through the engagement of the glass inlet 15 and the inner groove 22, the glass can be stably fixed in the door without shaking or falling off, thereby improving the overall aesthetics and safety of the door.

[0033] Furthermore, such as Figure 4 As shown, the side plate 4 has a narrow design, and the side wall of the pipe fitting 1 has a slotted groove. The width of the side plate 4 matches the width of the slot, and the side plate 4 is fixed to the outer wall of the pipe fitting 1 by bolts. This design allows the side plate 4 to be easily installed on the pipe fitting 1 and forms a tight connection with it. Through the positioning function of the slotted groove, the side plate 4 can be accurately installed in the predetermined position, improving the accuracy and efficiency of installation. At the same time, the tightening effect of the bolts ensures a stable connection between the side plate 4 and the pipe fitting 1.

[0034] Furthermore, such as Figure 5 As shown, side panel 4 is a wide design, with its width matching the width of the side wall of pipe fitting 1. Side panel 4 is fixed to the outer wall of pipe fitting 1 using bolts. This design not only ensures the aesthetic harmony between side panel 4 and pipe fitting 1 but also achieves a stable connection through the tightening of the bolts. The tight fit between side panel 4 and pipe fitting 1 prevents the entry of dust and foreign objects, improving the sealing and durability of the door.

[0035] Furthermore, a pivot 32 is connected to the bottom of the pivot seat 3. This design allows the door to rotate around the pivot 32, realizing the opening and closing function of a swing door. The stable connection of the pivot 32 ensures the smoothness and stability of the door during opening and closing, improving the comfort and durability of the door. At the same time, the design of the pivot 32 also facilitates the installation and adjustment of the door, reducing installation difficulty and maintenance costs.

[0036] In use, the extremely narrow mortise and tenon structure for assembling a swing door of this utility model involves first aligning the top locking block 21 of the connector 2 with the locking groove 12 inside the pipe 1 and inserting it to achieve a locking fit. Simultaneously, the bottom of the connector 2 securely engages with the support groove 13 inside the pipe 1, ensuring a stable position of the connector 2 within the pipe 1. This plug-in connection method simplifies the installation process, improves the stability of the connection, and ensures that the door will not loosen or detach during long-term use.

[0037] The rotating shaft seat 3 is precisely inserted into the socket 11 on the pipe fitting 1 via the insert block 31 on one side, thus achieving a stable positioning of the rotating shaft seat 3 on the pipe fitting 1. Subsequently, the insert block 31 is locked and fixed by the first bolt 5 on the inside of the pipe fitting 1, and the end of the first bolt 5 is pressed and fixed on the support plate 14, further ensuring the stability of the rotating shaft seat 3.

[0038] Choose either a narrow or wide side panel 4 as needed. For the narrow side panel 4, align it with the groove on the side wall of the pipe fitting 1 and fix it to the outer wall of the pipe fitting 1 with bolts. The groove serves as a positioning feature to ensure accurate installation of the side panel 4. For the wide side panel 4, its width matches the width of the side wall of the pipe fitting 1, and it is also fixed to the outer wall of the pipe fitting 1 with bolts to achieve a tight fit and stable connection. The installation of the side panel 4 enhances the structural strength of the door and effectively resists external impacts and pressure.

[0039] If glass needs to be installed in the door, the bottom end of the glass is inserted into the glass inlet 15 on the top wall of the fitting 1, and engages with the inner groove 22 on the top of the connector 2. This design allows the glass to be easily installed in the door and forms a tight connection with the door, improving the door's aesthetics and security.

[0040] The bottom of the pivot seat 3 is connected to a pivot 32, which allows the door to rotate around the pivot 32. When it is necessary to open or close the door, the door is pushed or pulled to rotate around the pivot 32, thus realizing the opening and closing function of the swing door.

[0041] The robust connection of the pivot 32 ensures the stability and smoothness of the door during opening and closing.
