Description

Technical Field

[0001] The utility model relates to the technical field of mortise and tenon structures, in particular to a stable and reliable triangular mortise and tenon structural part. Background Art

[0002] Ancient Chinese architecture uses wood and bricks as the main building materials, and the main structural method of wooden frame structures is mortise and tenon structure. It is built with main components such as columns, beams, and purlins. The joints between each component are matched with mortise and tenon joints to form a flexible frame.

[0003] The mortise and tenon joint is an extremely ingenious invention. This way of connecting components makes the traditional Chinese wooden structure a special flexible structure that surpasses the contemporary building frames, frameworks or steel frames. It can not only withstand large loads, but also allow a certain amount of deformation. Under seismic loads, it can offset a certain amount of seismic energy through deformation and reduce the seismic response of the structure.

[0004] However, in existing woodworking operations, mortise and tenon structures are gradually replaced by connection methods such as screws and glue, which invisibly causes the presence of harmful substances such as formaldehyde in the processed furniture or home furnishings, or consumes a large number of screws, and the stability of the screw connection itself is not high. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a stable and reliable triangular mortise and tenon structure which can be stably connected without external objects.

[0006] The utility model is implemented as follows: a stable and reliable triangular mortise and tenon structure comprises three identical connecting rods, wherein the three connecting rods comprise a rod body, one end of the rod body is provided with a tenon protruding outward, and the other end of the rod body away from the tenon is provided with a tenon groove, the three connecting rods are placed in pairs at acute angles, and the tenon on each connecting rod is embedded in the tenon groove of the connecting rod adjacent to it through the form of a mortise and tenon, and the three connecting rods are connected and enclosed in sequence to form the triangular mortise and tenon structure.

[0007] Furthermore, the rod body has an inward end surface arranged inwardly and an outward end surface arranged outwardly, and the length of the outward end surface is greater than that of the inward end surface.

[0008] Furthermore, both ends of the rod body have outer end surfaces that are arranged inclined toward each other.

[0009] Furthermore, the tongue and groove are arranged to penetrate from the inner end surface to the outer end surface.

[0010] Furthermore, the height of the tenon groove is greater than or equal to the height of the rod body.

[0011] Furthermore, the tongue and groove are arranged in an inclined shape.

[0012] Furthermore, the length of the tenon is the same as the height of the tenon groove.

[0013] Furthermore, one side of the tenon is arranged flush with one side of the rod body.

[0014] Furthermore, one side of the tenon is arranged flush with the inward end surface of the rod body.

[0015] Furthermore, when the three connecting rods are embedded in each other, the outward end surface is arranged flush with the outer end surface.

[0016] Compared with the prior art, the stable and reliable triangular mortise and tenon structure provided by the utility model is achieved by three connecting rods of the same structure being embedded and connected to each other in the form of mortise and tenon, and enclosing an equilateral triangle mortise and tenon structure, so that the three connecting rods form a stable triangular structure, without the need for screws or glue, with little harm, and can be disassembled and reassembled for repeated use.

[0026] A stable and reliable triangular mortise and tenon structure comprises three identical connecting rods 10, wherein the three connecting rods 10 comprise a rod body 11, one end of the rod body 11 is provided with a tenon 12 protruding outwardly, and the other end of the rod body 11 away from the tenon 12 is provided with a tenon groove 13, the three connecting rods 10 are placed at an acute angle in pairs, and the tenon 12 on each connecting rod 10 is embedded in the tenon groove 13 of the adjacent connecting rod 10 through the form of a tenon, and the three connecting rods 10 are connected and enclosed in sequence to form a triangular mortise and tenon structure; in this way, a triangular mortise and tenon structure is formed, and the three rod bodies 11 are completely connected, and a stable mortise and tenon connection can be formed without using screws or adhesives, and the structure is stable.

[0027] The stable and reliable triangular mortise and tenon structure provided above is formed by three connecting rods 10 of the same structure being embedded and connected to each other in the form of mortise and tenon, and enclosing an equilateral triangle mortise and tenon structure, so that the three connecting rods 10 form a stable triangular structure, without the need for screws or glue, with little harm, and can be disassembled and reassembled for repeated use.

[0028] The rod body 11 has an inward end surface 111 arranged inwardly and an outward end surface 112 arranged outwardly, and the length of the outward end surface 112 is greater than that of the inward end surface 111 .

[0029] In this embodiment, the two ends of the rod body 11 are respectively provided with outer end surfaces 113 arranged obliquely toward each other. In this way, the rod bodies 11 can increase the fit contact when they abut against each other, thereby increasing the protection of the rod bodies 11 during installation.

[0030] In this embodiment, the tenon groove 13 is arranged along the direction from the inner end surface 111 to the outer end surface 112. In this way, the contact area between the tenon 12 and the tenon groove 13 can be increased, thereby increasing the stability of the tenon and mortise engagement structure.

[0031] The height of the tenon groove 13 is greater than or equal to the height of the rod body 11 .

[0032] In this embodiment, the tenon groove 13 is arranged in an inclined shape. In this way, the height of the tenon groove 13 is greater than the height of the rod body 11, thereby increasing the contact area between the tenon 12 and the tenon groove 13, thereby increasing the stability of the tenon and mortise engagement structure.

[0033] In this embodiment, the length of the tenon 12 is the same as the height of the tenon groove 13. In this way, the outer end surface 113 of the rod body 11 can fit in contact with the inner end surface 111 of the rod body 11, thereby increasing the stability of the triangular mortise and tenon structure.

[0034] In this embodiment, one side of the tenon 12 is flush with one side of the rod body 11; one side of the tenon 12 is flush with the inward end surface 111 of the rod body 11. In this way, the flatness between the rod body 11 and the tenon 12 can be protected, thereby increasing the stability of the tenon 12 structure.

[0035] In this embodiment, when the three connecting rods 10 are embedded in each other, the outward end surface 112 is flush with the outer end surface 113. In this way, a triangular mortise and tenon structure is formed, so that the three rod bodies 11 are completely connected.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
