Description

Technical Field

[0001] This utility model relates to the field of building and furniture connection technology, and in particular to a mortise and tenon structure. Background Technology

[0002] Mortise and tenon joints are a common connection method in traditional Chinese architecture and furniture. They connect various components together through the cooperation of tenons and mortises, without the need for nails or other connectors. This structure not only has good stability and durability, but also reflects a unique aesthetic beauty. It is an important representative of traditional Chinese craftsmanship. In the modern construction and furniture manufacturing industry, mortise and tenon joints still have important application value. With people's increasing emphasis on environmental protection and sustainable development, as well as the demand for the inheritance and innovation of traditional craftsmanship, mortise and tenon joints are receiving more and more attention due to their natural, disassembly, and recyclable characteristics.

[0003] Currently, door and window connectors are generally directly connected and fixed using multiple screws, and the pivot seat is installed on the door frame with bolts. This installation and fixing method is prone to loosening and not being tight enough during long-term use.

[0004] An existing patent (publication number: CN220469711U) discloses a mortise and tenon structure. This utility model uses structural components such as a second pipe, a second plug, and a shaped component to fix the horizontally arranged second pivot seat. After fixing, it ensures that it is tight and will not loosen. Moreover, the various components are matched with each other through the mortise and tenon structure, which will not cause loosening, and ensures that the doors and windows are more secure in use.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing traditional mortise and tenon structures present numerous problems in practical applications. On one hand, their manufacturing process is complex, requiring extremely high levels of craftsmanship. The dimensional accuracy and tightness of the tenons and mortises must be precisely controlled; otherwise, the structural stability and robustness will be affected. In modern industrialized production environments, the number of craftsmen skilled in traditional mortise and tenon techniques is limited, making it difficult to meet the demands of large-scale production. On the other hand, traditional mortise and tenon structures have certain limitations when dealing with complex stress conditions. For example, when buildings are subjected to external forces such as earthquakes or strong winds, or when furniture is subjected to frequent shaking or collisions during use, the mortise and tenon joints are prone to wear and loosening, affecting the structure's lifespan. Furthermore, traditional mortise and tenon structures are not very versatile, only suitable for connecting components of specific types and sizes, and cannot be widely applied to various building or furniture components of different specifications, thus limiting their application scope in actual production.

[0006] Therefore, a mortise and tenon structure is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a mortise and tenon structure that can solve many problems existing in the practical application of the traditional mortise and tenon structure. On the one hand, its manufacturing process is complex and requires a high level of skill from craftsmen. The dimensional accuracy and tightness of the tenon and mortise need to be precisely controlled, otherwise it will affect the stability and firmness of the structure. In the modern industrialized production environment, the number of craftsmen who are skilled in the traditional mortise and tenon process is limited, making it difficult to meet the needs of large-scale production. On the other hand, the traditional mortise and tenon structure has certain limitations in dealing with complex stress conditions. For example, when a building is subjected to external forces such as earthquakes or strong winds, or when furniture is subjected to frequent shaking or collisions during use, the mortise and tenon joints are prone to wear and loosening, affecting the service life of the structure. In addition, the traditional mortise and tenon structure does not perform well in terms of structural versatility. It is only suitable for connecting components of specific types and sizes and cannot be widely applied to various building or furniture components of different specifications, which limits its application scope in actual production.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a mortise and tenon structure, comprising a tenon and a mortise, wherein a mortise and tenon assembly is provided between the tenon and the mortise;

[0009] The mortise and tenon assembly includes a main mortise on the front side of the tenon, an adjustment groove inside the tenon, a main tenon slidably connected inside the adjustment groove, the rear side of the main tenon being inserted into the main mortise, a threaded tube fixedly connected inside the main tenon, an adjustment screw threadedly connected inside the threaded tube, the adjustment screw threadedly connected inside the threaded tube, the front side of the adjustment screw penetrating the front side of the adjustment groove, an adjustment knob fixedly connected to the front side of the adjustment screw, and a tightening structure provided on the inner side of the main mortise and the outer side of the main tenon.

[0010] Preferably, the tightening structure includes secondary mortises on both sides of the interior of the tenon, the secondary mortises being connected to the main mortises, and trapezoidal grooves being provided on both sides of the interior of the tenon, the trapezoidal grooves being connected to the adjustment grooves.

[0011] Preferably, elastic connecting blocks are glued to both sides of the main tenon, and the elastic connecting blocks are slidably connected to the inside of the trapezoidal groove.

[0012] Preferably, a secondary tenon is bonded to the outer side of the elastic connecting block, the secondary tenon is slidably connected inside the trapezoidal groove, and the rear side of the secondary tenon is inserted into the secondary mortise.

[0013] Preferably, a pressure pad is bonded to the rear side of the threaded tube, the pressure pad being located inside the rear side of the main tenon and the pressure pad being located behind the adjusting screw.

[0014] Preferably, the front side of the adjustment knob has a slot, which is used in conjunction with a flathead screwdriver.

[0015] Preferably, a cushioning pad is bonded to the inside of the secondary mortise, and the inner side of the cushioning pad contacts the outer side of the secondary tenon.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a mortise and tenon assembly, provides sliding space for the movable main tenon through the adjustment groove inside the tenon. The threaded tube inside the main tenon cooperates with the adjustment screw. When the adjustment knob is turned, the adjustment screw is driven in the threaded tube, precisely controlling the sliding of the main tenon in the adjustment groove and changing its insertion depth into the main mortise. This design significantly reduces the matching requirements for dimensional accuracy when making the main tenon and the main mortise. In modern industrial production, ordinary workers can easily complete the mortise and tenon installation and adaptation by relying on this adjustment mechanism, eliminating the dependence on highly skilled craftsmen, significantly improving production efficiency, and meeting the needs of large-scale production. At the same time, the adjustable main tenon can flexibly adapt to mortise materials of different thicknesses. Whether it is the connection of beams and columns of different specifications in buildings or the splicing of various boards in furniture manufacturing, a stable connection can be achieved, expanding the scope of application and no longer being limited to specific types and sizes of components.

[0019] 2. By setting up a tightening structure, this application increases the connection point between the main tenon of the tenon and the main mortise of the mortise, making the external force more evenly distributed when the structure is under stress. In complex stress scenarios such as earthquakes, strong winds, or frequent shaking and collisions of furniture, this structure can effectively limit the relative displacement of the main tenon and the main mortise, reduce wear and loosening at the connection, enhance the stability and firmness of the structure, and extend the service life of the structure.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A mortise and tenon structure includes a tenon 1 and a mortise 2, with a mortise and tenon component 3 provided between the tenon 1 and the mortise 2;

[0030] The mortise and tenon assembly 3 includes a main mortise 31 opened on the front side of the tenon 2. An adjustment groove 32 is opened inside the tenon 1. A main tenon 33 is slidably connected inside the adjustment groove 32. The rear side of the main tenon 33 is inserted into the main mortise 31. A threaded tube 34 is fixedly connected inside the main tenon 33. An adjustment screw 35 is threadedly connected inside the threaded tube 34. The front side of the adjustment screw 35 passes through the front side of the adjustment groove 32. An adjustment knob 36 is fixedly connected to the front side of the adjustment screw 35. A tightening structure 37 is provided on the inner side of the main mortise 31 and the outer side of the main tenon 33.

[0031] In this embodiment: by setting the tenon and mortise assembly 3, the adjusting groove 32 in the tenon 1 provides sliding space for the movable main tenon 33. A threaded tube 34 is fixed inside the main tenon 33. The threaded tube 34 cooperates with the adjusting screw 35. When the operator rotates the adjusting knob 36, the adjusting screw 35 performs threaded transmission in the threaded tube 34. Since the front end of the adjusting screw 35 passes through the front side of the adjusting groove 32 and is connected to the adjusting knob 36, this rotation action can accurately control the sliding of the main tenon 33 in the adjusting groove 32, thereby changing the depth of the main tenon 33 inserted into the main mortise 31. This design brings many advantages. On the one hand, it greatly reduces the matching requirements for dimensional accuracy when manufacturing the main tenon 33 and the main mortise 31. In modern industrial production, ordinary workers can easily complete the installation and fitting of the tenon and mortise by relying on this adjustment mechanism, freeing them from the need for high-level skills. The high reliance on craftsmen significantly improves production efficiency and meets the needs of large-scale production. On the other hand, the adjustable main tenon 33 can flexibly adapt to mortise 2 of different thicknesses. Whether it is the connection of beams and columns of different specifications in buildings or the splicing of various boards in furniture manufacturing, a stable connection can be achieved, effectively expanding the application range of this mortise and tenon structure, so that it is no longer limited to specific types and sizes of components. In addition, the auxiliary tightening structure 37 set on the inner side of the main mortise 31 and the outer side of the main tenon 33 increases the connection points between the two, making the external force more evenly distributed when the structure is under stress. When facing complex external forces such as earthquakes and strong winds, or when furniture shakes or collides frequently, the auxiliary tightening structure 37 can effectively limit the relative displacement between the main tenon 33 and the main mortise 31, reduce wear and loosening at the connection, enhance the stability and firmness of the structure, and extend its service life.

[0032] Specifically, such as Figure 4 As shown, the auxiliary tightening structure 37 includes secondary mortises 371 opened on both sides inside the tenon 2. The secondary mortises 371 are connected to the main mortises 31. Trapezoidal grooves 372 are opened on both sides inside the tenon 1. The trapezoidal grooves 372 are connected to the adjustment grooves 32.

[0033] Specifically, such as Figure 4 As shown, elastic connecting blocks 373 are glued to both sides of the main tenon 33, and the elastic connecting blocks 373 are slidably connected to the inside of the trapezoidal groove 372.

[0034] Specifically, such as Figure 4 As shown, a secondary tenon 374 is bonded to the outer side of the elastic connecting block 373. The secondary tenon 374 is slidably connected inside the trapezoidal groove 372, and the rear side of the secondary tenon 374 is inserted into the secondary mortise 371.

[0035] In this embodiment: by setting the auxiliary tightening structure 37, the secondary mortises 371 on both sides of the mortise 2 are connected to the main mortises 31, and the trapezoidal groove 372 in the tenon 1 is connected to the adjusting groove 32. The elastic connecting blocks 373 on both sides of the main tenon 33 drive the secondary tenon 374 to slide in the trapezoidal groove 372 and insert into the secondary mortises 371, forming a multi-directional connection. When the structure is under stress, the secondary tenon 374 and the secondary mortises 371 work together with the main tenon 33 to share the external force, making the overall force more uniform. The elastic connecting blocks 373 can generate elastic deformation when under stress, buffer the impact force, reduce the hard collision between the tenon and the mortise, effectively limit the relative displacement between the main tenon 33 and the main mortise 31, reduce the wear and loosening risk at the connection, and significantly improve the stability and durability of the tenon and mortise structure.

[0036] Specifically, such as Figure 3 As shown, a pressure pad 4 is bonded to the rear side of the threaded tube 34. The pressure pad 4 is located inside the rear side of the main tenon 33 and is located behind the adjusting screw 35.

[0037] Specifically, such as Figure 3 As shown, a slot is provided on the front side of the adjustment knob 36, which is used in conjunction with a flathead screwdriver.

[0038] In this embodiment: By setting a pressure pad 4, which is bonded to the rear side of the threaded tube 34, when the adjusting screw 35 is rotated to its last end and its end contacts the front side of the pressure pad 4, the pressure pad 4 can provide a buffering effect, allowing the user to intuitively perceive the adjustment limit and avoid structural damage caused by excessive twisting of the threaded tube 34. The slot on the front side of the adjusting knob 36 is adapted to a flathead screwdriver, which can precisely control the rotation of the adjusting screw 35 during operation. This not only makes the extension and retraction adjustment of the main tenon 33 more labor-saving and precise, reducing the difficulty of manual operation, but also ensures that the main tenon 33 and the main mortise 31 fit tightly, greatly improving the installation efficiency.

[0039] Specifically, such as Figure 5 As shown, a buffer pad 5 is glued inside the secondary mortise 371, and the inner side of the buffer pad 5 contacts the outer side of the secondary tenon 374.

[0040] Specifically, such as Figure 6 As shown, the inner side of the buffer pad 5 is provided with anti-slip texture, which contacts the outer side of the secondary tenon 374.

[0041] In this embodiment: By setting a buffer pad 5, the inner side of which is in close contact with the secondary tenon 374, and the anti-slip texture further increases the friction. When the secondary tenon 374 is inserted or subjected to force, the buffer pad 5 absorbs the impact force through its own elastic deformation, reducing the direct friction and wear between the secondary tenon 374 and the secondary mortise 371. The anti-slip texture enhances the positioning effect of the secondary tenon 374, preventing it from sliding in the secondary mortise 371, ensuring that it can remain stable under complex external forces, and extending the service life of the tenon and mortise structure.

[0042] Working principle: In the process of using the mortise and tenon structure, first, according to the thickness of the component, use a flathead screwdriver to turn the adjustment knob 36. The adjustment screw 35 is driven in the threaded tube 34, which drives the main tenon 33 to slide in the adjustment groove 32, adjusts the depth of its insertion into the main mortise 31, and completes the initial fit. During installation, the main tenon 33 is inserted into the main mortise 31. Simultaneously, the elastic connecting blocks 373 on both sides of the main tenon 33 drive the secondary tenon 374 to slide along the trapezoidal groove 372 and insert into the secondary mortise 371, forming a multi-directional connection between the main and secondary tenons. During use, when the structure is subjected to external forces, such as earthquakes or furniture shaking, the elastic connecting blocks 373 deform to buffer the impact. The secondary tenon 374 and the secondary mortise 371 work together with the main tenon 33 to disperse the external force, reducing the relative displacement between the main tenon 33 and the main mortise 31 and reducing wear. The buffer pad 5 inside the secondary mortise 371 further absorbs the impact force through elastic deformation, and its inner anti-slip texture increases friction to prevent the secondary tenon 374 from sliding. When adjusting the main tenon 33, the pressure pad 4 provides buffering when the adjusting screw 35 is rotated to the limit position, avoiding over-adjustment and damage to the structure. The slotted design, combined with a screwdriver, ensures precise and labor-saving adjustment, ensuring a tight fit between the main tenon 33 and the main mortise 31, achieving a stable connection and long-term reliable use of the structure.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
