[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a mortise and tenon display frame is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-7 As shown, a mortise and tenon display frame according to an embodiment of the present utility model includes a horizontal connecting pipe 1 and a vertical connecting pipe 2. Both ends of the horizontal connecting pipe 1 and the vertical connecting pipe 2 are provided with connectors 3. Circular or square tube components can be selected according to actual display needs. The material can be wood, metal, or plastic. The connectors 3 are provided with beveled edges 31, and two sets of beveled edges 31 are fitted together. Limiting holes 32 and limiting grooves 33 are opened on the inner side of the beveled edges 31. A connecting pipe 34 is fixedly connected to the side of the connector 3 away from the beveled edges 31. A fixing kit 4 is connected in the limiting hole 32. The fixing kit 4 is inserted into the limiting hole 32 to form a frame 7. The fixing kit 4 is provided with positioning rods 41 and limiting blocks 42. Two sets of positioning rods 41 are located on the side of the limiting blocks 42 and inserted into the limiting holes 32. The limiting blocks 42 are firmly connected in the limiting grooves 33.

[0027] In one embodiment, the horizontal connecting pipe 1 and the vertical connecting pipe 2 have openings 5 ​​on both sides, and protrusions 51 for sliding connection of the connecting pipe 34 are provided inside the openings 5. An array of protrusions 51 are distributed on the inner wall of the openings 5. After connection, the friction and connection strength between the two can be increased, making the structure of the display frame more stable.

[0028] In one embodiment, the horizontal connecting pipe 1 and the vertical connecting pipe 2 are circular or square tubular components, and a stabilizing member 6 is connected to the inner side of the horizontal connecting pipe 1 and the vertical connecting pipe 2. The stabilizing member 6 can be in the form of reinforcing ribs or inner lining plates to further enhance the strength and stability of the connecting pipes, prevent deformation during use, and ensure that the display frame can reliably fix the displayed items.

[0029] In one embodiment, the surface of the connecting piece 34 is provided with a plurality of guide grooves 341, which are matched with the protrusions 51. Thus, the guide effect is achieved, so that the connecting pipe 34 can be accurately and quickly inserted into the transverse connecting pipe 1 and the longitudinal connecting pipe 2, and the stability of the connection is also increased, so that the connecting pipe 34 is prevented from rotating or moving during use.

[0030] In one embodiment, the two groups of connecting pieces 3 are connected by the inclined edges 31 to form a vertical mechanism.

[0031] In one embodiment, the positioning rod 41 and the limiting groove 33 and the limiting block 42 and the limiting hole 32 are in interference connection. The interference connection effectively prevents the loosening and separation between the connecting pieces 3, and enhances the overall stability of the display frame. At the same time, the interference connection does not require additional glue, screws and other connection methods, so that the surface of the display frame is kept clean and beautiful, and the installation process and cost are reduced.

[0032] Working principle: The transverse connecting pipe 1 and the longitudinal connecting pipe 2 are connected by the connecting pieces 3, and the two groups of inclined edges 31 are connected to ensure the accurate perpendicularity between the transverse connecting pipe 1 and the longitudinal connecting pipe 2, thereby constructing a regular and stable frame 7 basic structure. The display canvas is laid on the surface of the frame 7, and the edges of the canvas are turned inward along the side ends of the transverse connecting pipe 1 and the longitudinal connecting pipe 2, and the connecting pieces 3 are fixed by the fixing kit 4. The accurate positioning of the limiting hole 32 on the inner side of the inclined edge 31 provides an accurate insertion position for the positioning rod 41 of the fixing kit 4, and the limiting groove 33 is tightly matched with the limiting block 42, so that the relative position of the connecting piece 3 can be accurately fixed after the installation of the fixing kit 4, thereby preventing displacement or loosening of the connecting piece 3 under stress. The cooperation between the guide grooves 341 on the surface of the connecting pipe 34 and the protrusions 51 in the openings 5 on both sides of the transverse connecting pipe 1 and the longitudinal connecting pipe 2 also plays an important role in the stability of the frame 7. During assembly, the protrusions 51 slide along the guide grooves 341, so that the connecting pipe 34 can be accurately and correctly inserted into the openings 5, and after insertion, the tight contact between the protrusions 51 and the guide grooves 341 increases the friction force and the connection strength between the connecting pipe 34 and the transverse connecting pipe 1 and the longitudinal connecting pipe 2.

[0033] In the present application, unless otherwise specified and limited, the terms "installation", "arrangement", "connection", "fixation", "screw connection" and the like should be understood in a broad sense. For example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specified, the specific meaning of the above terms in the present application can be understood according to the specific circumstances by those skilled in the art.

[0034] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
