Abstract

The invention provides a mortise and tenon structure based on a hollow material. The mortise and tenon structure comprises a hollow main body piece, wherein a circular base is arranged on the hollow main body piece; a transition bulge is arranged on one side of the circular base; a flake card face is formed in the transition bulge; and a clearance is formed between the flake card face and the circular base and can allow another flake card face to be inserted and clamped in the clearance. According to the mortise and tenon structure disclosed by the invention, the circular base surrounding theouter surface of the hollow main body piece is arranged on the hollow main body piece, and the transition bulge and the flake card face are formed in one surface of the circular base, so that the mortise and tenon structure is constructed on the hollow main body piece. According to the arrangement of the circular base, on one hand, the stress tolerance of the hollow main body piece is improved, sothat the thin wall of the hollow main body piece is avoided from being torn or broken after the mortise and tenon structure is mounted; on the other hand, a basis is provided for constructing the mortise and tenon structure on the hollow main body piece.

Example Embodiment

[0021] The embodiments of the present invention are described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions.
[0022] The orientation shown in the drawings should not be construed as limiting the specific protection scope of the present invention, and is only for reference and understanding of the preferred embodiments. The product components shown in the drawings can be changed in position or increased in number or simplified in structure.
[0023] The "connection" described in the specification and the mutual "connection" relationship between the components shown in the drawings can be understood as a fixed connection or a detachable connection or an integral connection; it can be directly connected or connected through an intermediate medium, A person of ordinary skill in the art can understand the connection relationship according to the specific situation, and can obtain the method of screwing, riveting, welding, snapping, or embedding, etc., to perform different implementation alternatives in an appropriate manner.
[0024] The orientation words such as up, down, left, right, top and bottom mentioned in the specification and the orientation shown in the drawings, each component can be in direct contact or through other features between them; if it is above, it can be directly above And diagonally above, or it simply means higher than other things; other directions can also be understood by analogy.
[0025] The manufacturing materials of the parts with solid shapes shown in the specification and drawings can be made of metal materials or non-metallic materials or other synthetic materials; the machining processes used for parts with solid shapes can be stamping, forging, casting , Wire cutting, laser cutting, casting, injection molding, number milling, three-dimensional printing, machining, etc.; those of ordinary skill in the art can adaptively select or combine selections according to different processing conditions, costs, and precision, but not limited to the above Materials and manufacturing processes.
[0026] A mortise and tenon structure based on hollow materials, such as Figure 1 to Figure 7 As shown, it includes a hollow main body part 10, on which is provided an annular base 20, and a transition protrusion 30 is provided on one of the surfaces of the annular base 20, and the transition protrusion 30 is provided There is a sheet-shaped card surface 40, a gap is provided between the sheet-shaped card surface 40 and the annular base 20, and the gap can accommodate another sheet-shaped card surface 40 to be inserted and clamped therein.
[0027] In use, at least two mortise and tenon structures based on hollow materials are required, one of which is used as a mortise piece and one as a tenon piece, depending on the actual installation situation. In the two mortise and tenon structures based on hollow material, the chip card The orientations of the faces 40 are inconsistent and cooperate with each other to realize the snap fit of the mortise and tenon structure, such as figure 1 As shown, the mortise and tenon structure based on hollow materials is used as a vertical beam. On the other hand, when another mortise and tenon structure based on hollow materials is used as a beam, the sheet-shaped clamping surface 40 on the beam is used as a beam. It is arranged perpendicular to the sheet-shaped card surface 40 as the vertical beam. It should be understood that the sheet-shaped card surface 40 and its annular base 20 are not only parallel, but also include a sheet-shaped card surface 40 arranged obliquely to achieve the mortise and tenon engagement in an oblique direction.
[0028] In the present invention, an annular base 20 surrounding the outer surface of the hollow main body 10 (hollow material) is provided on the hollow main body member 10, and then a transition protrusion 30 and a sheet-shaped card surface 40 are provided on one of the surfaces of the annular base 20 to A mortise and tenon structure is constructed on the hollow main part 10. The arrangement of the annular base 20 improves the stress bearing strength of the hollow main part 10 on the one hand, so that after the mortise and tenon structure is installed, the thin wall of the hollow main part 10 is prevented from tearing or breaking. On the other hand, it also provides a foundation for constructing a tenon and tenon structure on the hollow main body.
[0029] In the embodiment, such as Figure 4 , 5 , 6, and 7, there is a clamping pattern 50 on the inner side of the sheet-shaped card surface 40, and the clamping pattern 50 can be wedged in cooperation with the clamping pattern 50 on the inner side of another sheet-shaped card surface 40. When the mortise and tenon structure is installed, the mortise and tenon connection is smoother and more stable.
[0030] In the embodiment, such as Figure 1 to 7 As shown, the cross section of the hollow body 10 is a square, and correspondingly, the inner ring of the annular base 20 has a square structure; of course, the cross section of the hollow body 10 can also be a circle, and the ring base 20 The inner ring of is a circular structure; or, the cross section of the hollow main body 10 can also be a regular pentagon or a regular hexagon.
[0031] In the embodiment, the hollow body part 10 is a wood-plastic structural part. Of course, the hollow body part 10 may also be a hollow metal part.
[0032] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that the present invention can be made without departing from the principle and spirit scope of the present invention defined by the claims. Make various changes or modifications. Therefore, the detailed description of the embodiments of the present disclosure is only used for explanation, not for limiting the present invention, but the scope of protection is limited by the content of the claims.
