Description

Technical Field

[0001] This utility model belongs to the field of splicing door and window technology, specifically relating to splicing doors and windows with mortise and tenon structure. Background Technology

[0002] Mortise and tenon joints are a common connection method in traditional Chinese architecture and furniture, primarily used between two wooden components. They employ a convex-concave joint, where the protruding part is called the tenon (or tenon head), and the recessed part is called the mortise (or mortise hole, mortise groove). The mortise and tenon structure connects the two parts through their interlocking. This connection method is not only widely used in ancient Chinese architecture but is also a crucial technique in traditional Chinese furniture making. In the production of solid wood doors and windows, mortise and tenon joints are frequently used to join the components.

[0003] Existing modular doors and windows, after being fixed together with mortise and tenon joints, mostly require secondary positioning and tightening of the mortise and tenon joints with separate wooden dowels. The overall operation is quite cumbersome, and when some parts of the doors and windows need to be replaced, it takes a long time to disassemble and replace the spliced ​​parts. Therefore, modular doors and windows with mortise and tenon structures are needed to help solve this problem. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific implementation method is a mortise and tenon joint structure for spliced ​​doors and windows, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mortise and tenon structure of the spliced ​​door and window includes a first frame 1 and a second frame 3. Both ends of the first frame 1 have protruding blocks 2, and both ends of the second frame 3 have snap-fit ​​grooves 4. Snap-fit ​​posts 7 protrude from the inside of the snap-fit ​​grooves 4. Snap-fit ​​holes 6 are formed on the protruding blocks 2, and the snap-fit ​​holes 6 and snap-fit ​​posts 7 engage with each other. The two snap-fit ​​holes 6 and the two snap-fit ​​posts 7 form a rectangular frame. Slots are formed on the inner sides of the snap-fit ​​holes 6 and snap-fit ​​posts 7, and window frames 5 are installed in these slots. The connecting post 7 is I-shaped, and a V-shaped top pressure groove 11 is provided at the center of the connecting post 7. A protruding plate is provided at the top of the top pressure groove 11. A top pressure assembly is installed at the protruding plate to assist the connecting post 7 in pressing to both sides. The top pressure assembly includes a knob 8 that is rotatably embedded in the protruding plate. A screw 9 is fixed at the bottom of the knob 8. A push block 10 is sleeved on the screw 9. The push block 10 is V-shaped and is snapped into the top pressure groove 11. There is a threaded connection between the screw 9 and the push block 10.

[0027] Through the cooperation between the snap-fit ​​post 7 installed on the second frame 3, the top pressure component at the snap-fit ​​post 7, and the snap-fit ​​hole 6 on the protruding block 2, etc., when working, the knob 8 can be turned, which drives the screw 9 to rotate as a whole. The screw 9 and the push block 10 are threadedly engaged, thereby causing the push block 10 to move down as a whole. When the push block 10 moves down, it causes the top pressure groove 11 to be opened, thereby opening the snap-fit ​​post 7 and making the snap-fit ​​post 7 stably snap-fitted in the corresponding position. This completes the overall positioning and fastening of the snap-fit ​​post 7, and avoids the problem of inconvenience in disassembling the entire door and window structure when the first frame 1 or the second frame 3 is partially damaged and needs to be disassembled in subsequent work. This improves the convenience of disassembling and replacing the door and window structure after damage.

[0028] The second frame 3 and the snap-fit ​​post 7 are provided with positioning holes 121 on their outer sides. Positioning pins 12 are inserted and installed in the positioning holes 121. A snap-fit ​​pad 41 is provided on the inner side of the snap-fit ​​groove 4. The snap-fit ​​pad 41 is attached to the outer side of the snap-fit ​​post 7. The snap-fit ​​pad 41 ensures that the protruding block 2 can be stably snapped and installed in the corresponding position during installation, and ensures that the snap-fit ​​groove 4 and the protruding block 2 can be stably snapped together after installation.

[0029] The bottom of the first frame 1 is symmetrically provided with mounting grooves 13, and the mounting grooves 13 are equipped with auxiliary moving wheels 14. By setting the detachable moving wheels 14 at the bottom of the first frame 1, the detachable moving wheels 14 can be installed at the mounting grooves 13 during transportation or movement to improve the moving efficiency of the door and window body and avoid the situation that it is difficult to move the solid wood door and window as a whole.

[0030] Working principle:

[0031] During installation, align the protruding block 2 with the snap-fit ​​groove 4 vertically, and insert the snap-fit ​​post 7 into the snap-fit ​​hole 6 to complete the initial positioning and fastening process between the first frame 1 and the second frame 3. Rotate the knob 8, which drives the lead screw 9 to rotate as a whole. The lead screw 9 and the push block 10 are threaded together, causing the push block 10 to move down as a whole. When the push block 10 moves down, it causes the top pressure groove 11 to be opened, thereby opening the snap-fit ​​post 7 and making the snap-fit ​​post 7 stably snap-fitted into the corresponding position, thus completing the overall positioning and fastening process of the snap-fit ​​post 7. Insert the positioning pin 12 into the positioning hole 121 to complete the secondary positioning and fastening process between the protruding block 2 and the second frame 3.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
