Description

Technical Field

[0001] The utility model relates to the technical field of the connection between thin plates or plates, in particular to an acrylic mortise and tenon structure. Background Technique

[0002] With the development of modern industry and the continuous improvement of consumers' requirements for product quality, the connection technology between different materials has become a very important research topic in many fields. Especially in the fields of furniture manufacturing, decoration, display rack construction, etc., acrylic materials are favored because of their unique transparency, good processing performance and aesthetics. However, there are still some problems to be solved urgently in the connection technology between acrylic materials and other materials (such as wood, metal, other plastics, etc.).

[0003] At present, the most common connection method between acrylic materials and other materials is to use chemical adhesives. Although this method can achieve a good connection effect, it has the following disadvantages: (1) The curing time of the adhesive is long, which affects the production efficiency; (2) After long-term use, the adhesive may age, crack or lose its viscosity, resulting in the loosening of the connection part; (3) The use of chemical adhesives will increase the risk of environmental pollution, which does not conform to the concept of green production;

[0004] Another common connection method is to fix acrylic materials and other materials through mechanical fasteners such as screws and rivets. For example, the patent with the publication number CN107630877B discloses a mortise and tenon component, which uses a metal - made mortise body as a connecting piece to connect a wooden piece provided with a tenon structure without using adhesives for auxiliary connection, which is green and environmentally friendly. Although the above - mentioned screws are relatively firm, they also have the following disadvantages: (1) Drilling is required during the installation process, which is easy to damage the acrylic material; (2) The mechanical fasteners are exposed outside, affecting the overall aesthetics; (3) It is difficult to disassemble, which is not conducive to the recycling and reuse of products.

[0005] In the traditional woodworking industry, the mortise and tenon technology is a non - adhesive connection method with a long history and wide application. However, it is difficult to apply it to acrylic materials. The hardness and elasticity of acrylic materials are different from those of wood, and traditional mortise and tenon designs may not be adaptable, lacking special mortise and tenon structure designs and technical standards for acrylic materials. Therefore, there is an urgent need for a new mortise and tenon structure suitable for the connection between acrylic materials and other materials to replace the existing chemical adhesives and mechanical fasteners such as screws and rivets. Content of the Utility Model

[0006] In order to solve the problem that the existing mortise and tenon structure is fastened by mechanical fasteners, and the processes such as drilling and screw fastening are easy to damage the material, the utility model provides an acrylic mortise and tenon structure. By introducing a silica gel block as an anchoring material in the mortise and tenon connection process, the problems of low connection strength, poor durability and difficult assembly are solved.

[0007] The utility model provides an acrylic mortise and tenon structure, which includes a first structural member and a second structural member. The first structural member is made of acrylic material, and the second structural member is made of wood, metal or plastic material. The first structural member and the second structural member are inserted or spliced to form an insertion surface or a splicing surface, and a bite groove is arranged on the insertion surface or the splicing surface, and a silica gel block is filled in the bite groove. The mechanical bite of the bite groove and the silica gel block replaces the traditional chemical adhesive and threaded fastener, which is green and environment-friendly and convenient for disassembly. Moreover, the elastic deformation of the silica gel block can fill the gap at the mortise and tenon joint to adapt to the expansion and deformation of the acrylic material.

[0008] Further, the first structural member and the second structural member are spliced to form a splicing surface. A first dovetail groove is arranged on the splicing surface of the first structural member, and a second dovetail groove is arranged on the splicing surface of the second structural member. The spliced first dovetail groove and the second dovetail groove form a bite groove. During the splicing process, the connection can be realized only by filling the silica gel block into the bite groove.

[0009] Further, the first dovetail groove and the second dovetail groove are symmetrically arranged with the splicing surface as the axis of symmetry, and the groove widths of the first dovetail groove and the second dovetail groove decrease towards the splicing surface side. The silica gel block is bitten by the relatively arranged dovetail grooves on the two structural members to realize stable connection.

[0010] Further, the first structural member and the second structural member are inserted to form an insertion surface. A slot for the second structural member to extend into is arranged on the first structural member, and the bite groove penetrates the insertion surfaces of the first structural member and the second structural member. The second structural member is restricted in the slot by the silica gel block filled on the insertion surface.

[0011] Further, the bite groove is columnar, the silica gel block is correspondingly arranged in a columnar shape, and semi-circular grooves are respectively arranged on the insertion surfaces of the first structural member and the second structural member to form a columnar bite groove. The filling effect of the columnar silica gel block is better than that of other shapes.

[0012] Further, the semi-circular grooves are arranged in the middle of the two side walls of the slot and communicate with the slot. The columnar silica gel block is filled on both sides of the second structural member to improve the stability of the mortise and tenon.

[0013] Further, the first structural member and the second structural member are inserted to form an insertion surface. An insertion block is arranged at the end of the first structural member, a slot for the insertion block to extend into is arranged on the second structural member, and a bite groove penetrating the second structural member is arranged above the slot. The stability of the mortise and tenon is improved through the cooperation of the insertion block, the slot and the silica gel block.

[0014] Further, positioning holes for accommodating the silica gel blocks are correspondingly formed on the insertion blocks inserted into the slots. The silica gel blocks pass through the second structural member and the insertion blocks in sequence, so that the insertion blocks are stably placed in the slots.

[0015] The beneficial effects of the present utility model are as follows:

[0016] The present utility model provides an acrylic mortise and tenon structure. By introducing a silica gel block as an anchoring material during the mortise and tenon connection of acrylic materials and other materials, and by optimizing the geometric shape and size of the mortise and tenon, it can effectively engage with other materials, and at the same time can adapt to the expansion and deformation of acrylic materials;

[0017] The silica gel can fill the tiny gaps at the mortise and tenon joints, improving the integrity of the structure. The softness of the silica gel can play a certain buffering role when subjected to external force impacts, reducing stress concentration, and can undergo appropriate deformation when being squeezed to absorb the stress generated during the connection process. The silica gel can also provide additional waterproof and dustproof functions. Description of the Drawings

Specific Embodiments

[0023] The following will clearly and completely describe the technical solutions of the present utility model with reference to the drawings. Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments.

[0024] To solve the problems that the long curing time of traditional chemical adhesives affects production efficiency, they are prone to aging and pollute the environment, and also to solve the problems that traditional mechanical connections such as screws and rivets require drilling, which is likely to damage acrylic materials, and are difficult to disassemble and not conducive to recycling. As Figures 1-3 shown, a tenon-mortise structure for acrylic is designed, including structural member 1 and structural member 2. Structural member 1 is made of acrylic, and structural member 2 is made of wood, metal or plastic. Structural member 1 and structural member 2 are inserted or spliced to form an insertion surface or a splicing surface, and a bite groove 3 is arranged on the insertion surface or the splicing surface, and a silica gel block 4 is filled in the bite groove 3.

[0025] Manufacturing process: Use a numerically controlled machine tool (CNC) or laser cutting to process the bite groove 3 with high precision to ensure the consistency and accuracy of each structural member; finely polish the cut tenons and mortises to remove the burrs generated during the cutting process and improve the surface finish; use special polishing tools such as fine sandpaper or polishing wheels to manually or mechanically polish the bite groove 3; perform pre-assembly according to the design requirements, and then perform final fixation after adjustment. Before formal assembly, use a fixture or a locator to pre-assemble and position the tenons and mortises to ensure the accurate relative position of the two; during the pre-assembly process, check the fit between the tenons and mortises, and finally fill the silica gel block 4 and apply slight pressure to fix it to complete the assembly.

[0026] Through the precisely designed tenon-mortise structure, mechanical biting between the acrylic structural member 1 and other material structural member 2 is realized, greatly improving the strength of the connection part; the silica gel block 4 can effectively absorb stress and avoid wear or fracture of the connecting parts caused by repeated stress during long-term use; the tenon-mortise structure allows for rapid assembly, reduces the dependence on tools, simplifies the assembly process, and improves production efficiency; no chemical adhesives are required, reducing the emission of harmful substances and meeting the requirements of green manufacturing; the tenon-mortise connection method can hide the connection traces and enhance the overall aesthetics of the product.

[0027] The tenon-mortise structure of the acrylic structural member 1 and other material structural member 2 includes but is not limited to forms such as straight tenons, dovetail tenons, and T-shaped tenons.

[0028] Example 1, dovetail tenon form, suitable for applications that require higher strength connections, such as Figure 1As shown, structural member 1 and structural member 2 are spliced to form a splicing surface. A dovetail groove 5 is provided on the splicing surface of structural member 1, and a dovetail groove 6 is provided on the splicing surface of structural member 2. The combined dovetail groove 5 and dovetail groove 6 form a locking groove 3. The dovetail groove 5 and dovetail groove 6 are symmetrically arranged with the splicing surface as the axis of symmetry, and the groove widths of the dovetail groove 5 and dovetail groove 6 decrease towards the splicing surface side. Splice structural member 1 and structural member 2 so that a locking groove 3 is formed on the splicing surface to ensure the accurate relative position of structural member 1 and structural member 2. Then, insert a silica gel block 4 that fits the shape of the locking groove 3 into the locking groove 3 to complete the assembly.

[0029] The tenon of the dovetail joint is designed in a shape similar to a dovetail, that is, one end is wide and the other end is narrow, with a trapezoidal cross-section. This design can provide better tensile strength and prevent the connecting piece from sliding along the joint. The silica gel block 4 is designed with a trapezoidal cross-section, and its size should be slightly smaller than the gap between the tenon and the mortise to ensure that it can be smoothly inserted and provide elastic support. Necessary surface treatments, such as sanding and sandblasting, are carried out on the acrylic material structural member 1 and other material structural member 2 to increase the friction coefficient and contact area of the material surface.

[0030] Embodiment 2, the T-shaped tenon form, is used for the connection requirements of complex structures, such as Figure 2 As shown, structural member 1 and structural member 2 are inserted into each other to form an insertion surface. A slot 7 is provided on structural member 1 for structural member 2 to extend into, and the locking groove 3 penetrates the insertion surfaces of structural member 1 and structural member 2. The locking groove 3 is cylindrical, and the silica gel block 4 is correspondingly set as cylindrical. Semi-circular grooves 8 are respectively provided on the insertion surfaces of structural member 1 and structural member 2 to form a cylindrical locking groove 3.

[0031] To ensure the connection stability, the semi-circular grooves 8 are provided in the middle of the two side walls of the slot 7 and communicate with the slot 7, so that the silica gel block 4 is placed on both sides of the slot 7, and the stability is good.

[0032] The cross-section of the main tenon is rectangular, and its length is slightly shorter than the depth of the main mortise to ensure that there is room to place the silica gel block 4 during the connection process. The width and height of the main tenon need to be precisely matched with the size of the main mortise to ensure the tightness of the connection; the cross-section of the secondary tenon is also rectangular, and its length and width should be coordinated with the main tenon to ensure the connection strength in the vertical direction. The height of the secondary tenon should be slightly less than the height of the main tenon to facilitate assembly; a stable T-shaped structure is formed at the connection part of the main tenon and the secondary tenon, with the main tenon located above the secondary tenon. The locking groove 3 at the connection part of the main tenon and the secondary tenon is filled and fixed with the silica gel block 4. The silica gel block 4 is designed with various shapes, and its size should be slightly smaller than the gap between the main tenon and the secondary tenon to ensure that it can be smoothly inserted and provide elastic support. Preferably, it is cylindrical. The cylindrical silica gel block 4 adapts to the slight deformation after the expansion of the acrylic material through its elastic deformation to ensure that the mortise and tenon structure is more stable.

[0033] Embodiment 3, straight tenon form, applicable to occasions where simple and rapid connection is required, such as Figure 3 As shown, structural member 1 and structural member 2 are inserted into each other and form an insertion surface. There can be multiple structural members 1. An insertion block 9 is provided at the end of structural member 1. An insertion slot 10 into which the insertion block 9 can extend is formed on structural member 2. A biting slot 3 penetrating structural member 2 is formed above the insertion slot 10. A positioning hole 11 for accommodating the silica gel block 4 is correspondingly formed on the insertion block 9 extending into the insertion slot 10. Insert the insertion block 9 at the end of structural member 1 into the insertion slot 10 of structural member 2 to ensure the accurate relative position of structural member 1 and structural member 2. Then, sequentially penetrate the columnar silica gel block 4 through the insertion slot 10 of structural member 2 and the positioning hole 11 on the insertion block 9 to complete the assembly.

[0034] Among them, the tenon is designed as a rectangular protrusion, that is, the insertion block 9, and its size is determined according to the thickness of the acrylic structural member 1 and the characteristics of the connected material. The mortise is a rectangular insertion slot 10 cut on another material, and its size is precisely matched with the tenon. The silica gel block 4 is designed as a rectangle or a cylinder, and its size should be slightly smaller than the gap between the tenon and the mortise to ensure that it can be smoothly embedded in the biting slot 3 and provide elastic support. The length and width of the silica gel block 4 should be similar to the corresponding dimensions of the tenon, while the height should be slightly lower than the depth of the mortise. The main function of the silica gel block 4 is to provide buffering during the process of inserting the tenon into the mortise, and play a role of fixing and sealing after the connection is completed, preventing the connection part from loosening or generating gaps.

[0035] The above description is illustrative rather than restrictive to the present utility model. Those of ordinary skill in the art understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, but all will fall within the protection scope of the present utility model.
