Description

Technical Field

[0001] The utility model belongs to the technical field of furniture, and particularly relates to a solid wood photo frame structure with mortise and tenon joints. Background Art

[0002] China, with its long history, has nurtured numerous precious artifacts, such as embroidery, calligraphy and painting, and paper-cutting, all of which are treasures of Chinese culture. When exhibited in museums, these artifacts are often framed to maximize their artistic appeal. The relationship between exhibits and frames is like the relationship between a person and clothing. Appropriate clothing can enhance a person's radiance, add charm, and highlight their inner qualities; inappropriate attire can diminish a person's image. Furthermore, frames can better guide viewers in appreciating exhibits and enhance the viewing experience. Regarding the choice of framing materials, metal, glass, or ceramic frames are too heavy, and traditional Chinese paintings and embroidery works tend to be framed in solid wood. Solid wood frames, with their rustic, elegant, simple, and textured qualities, perfectly complement the artistic style of embroidery paintings, lending them a more elegant and solemn quality.

[0003] However, traditional solid wood frames are mostly assembled by splicing metal or plastic frame hoops. For example, in the prior art, Chinese patent publication number CN202932511U discloses a picture frame with a motto, which includes an outer frame and an inner frame. The inner frame is embedded with a picture panel. The inner and outer frames are fixedly connected by connecting strips and / or connecting hollow flower pieces. The outer and inner frames may have the same or different shapes, and the outer and inner frames may be polygonal, circular, fan-shaped, or elliptical. The outer frame is made of multiple outer frame strips fixedly connected by frame hoops. Such picture frames have poor structural stability, are heavy, and lack texture.

[0004] In addition, in the existing manufacturing process of solid wood framing, the dovetail groove and tenon structure, as a classic and stable connection method, is widely used in the assembly process of solid wood framing. However, the dovetail groove and tenon structure also has certain limitations, especially in terms of ease of assembly and disassembly, thickness and service life. Specifically, the assembly process of solid wood framing connected with a dovetail groove and tenon structure usually requires that the exhibits be precisely fixed first, and then the four corners of the solid wood frame are fixed in turn through the complex dovetail groove and tenon structure. This step is not only cumbersome, but also time-consuming and labor-intensive, which greatly increases the difficulty of replacing or adjusting exhibits. In addition, in order to maintain the integrity of the dovetail groove and tenon structure, each frame edge must maintain a certain thickness, and the overall weight and volume of the solid wood frame will also increase accordingly; if the thickness is not enough to set the dovetail groove and tenon structure, it is easy to cause cracking at the connection, poor structural stability, shortened service life, and increased maintenance costs.

[0005] Therefore, there is an urgent need for a solid wood photo frame structure with mortise and tenon joints that is stable in structure, light in weight, and convenient for replacing exhibits. Summary of the Invention

[0006] In response to the problems in the related art, the present invention proposes a solid wood photo frame structure with mortise and tenon connections to overcome the above-mentioned technical problems existing in the existing related art. The mortise and tenon structure of the present invention, with its unique mutual splicing design, achieves a stable and tight connection between the solid wood frame edges, thereby improving the overall load-bearing capacity and stability of the photo frame; moreover, the embedding opening opened on the solid wood frame edge on at least one side of the photo frame body improves the convenience of taking out and placing exhibits, and is more practical.

[0011] Furthermore, the photo frame body includes a first frame side, a second frame side, a third frame side, and a fourth frame side that are sequentially spliced ​​together; wherein the first frame side is arranged opposite to the third frame side, the second frame side is arranged opposite to the fourth frame side, and the embedding opening is arranged on the first frame side;

[0012] It should be noted that since the mounting opening is open, in order to prevent impurities such as paper scraps and dust from entering through the mounting opening, the first frame edge can generally be set as the bottom of the photo frame body. When the exhibit is installed, the photo frame body stands on a plane that closes the mounting opening.

[0013] The second splicing structures are respectively provided at two ends of the first frame side and the third frame side, and the first splicing structures are respectively provided at two ends of the second frame side and the fourth frame side.

[0014] Furthermore, the embedding opening is in the shape of an elongated strip, with its head and tail ends extending back to each other and neither exceeding the tenon at both ends.

[0015] Furthermore, the first joint portion is provided with a mortise groove in the middle, and the second joint portion is provided with a tenon protruding in the middle;

[0016] The first splicing part is provided with wedge openings on the left and right sides of the mortise, and the second splicing part is provided with wedge portions protruding on the left and right sides of the tenon; when the first splicing part and the second splicing part are spliced ​​together, the inclined surface of the wedge portion fits with the inclined surface of the wedge opening.

[0021] Furthermore, the slots arranged along the lateral direction of the photo frame body are guide slots, and the slots arranged along the transverse direction of the photo frame body are limit slots.

[0022] Furthermore, in the same solid wood frame edge, the percentage of the depth of the groove to the thickness of the solid wood frame edge ranges from 40% to 50%.

[0023] Furthermore, the interior of the photo frame body is provided with at least two layers of core boards, and a hollow space is formed between the two layers of core boards for pressing exhibits at the front and back.

[0024] Furthermore, the two core plates are both transparent; the core plates are glass plates or plastic plates; it should be noted that the arrangement of two transparent core plates is suitable for double-sided display of exhibits, such as double-sided embroidery works;

[0025] Alternatively, one of the two core boards may be transparent. It should be noted that this single-sided transparent design is suitable for single-sided display of exhibits, such as Chinese paintings, calligraphy, etc.

[0026] Beneficial effects of the utility model:

[0027] (1) First, the mortise and tenon structure of the present invention achieves a stable and tight connection between the edges of the solid wood frame due to its unique interlocking design, namely the interference fit between the mortise of the first joint and the tenon of the second joint.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] like Figure 1-8 As shown, this embodiment provides a solid wood photo frame structure with mortise and tenon joints, including a photo frame body 1 for placing exhibits, the photo frame body 1 including multiple solid wood frame edges, each of which is sequentially spliced ​​head-to-tail by mortise and tenon structures 2 to form a closed frame; the mortise and tenon structure 2 includes a first splicing portion 21 and a second splicing portion 22 that are spliced ​​together, the first splicing portion 21 including at least a mortise groove 211, the second splicing portion 22 including at least a tenon 221, the tenon 221 being interference fit in the mortise groove 211;

[0042] At least one side of the solid wood frame is provided with an insertion opening 111 for taking out / putting in exhibits, and the insertion opening 111 is arranged along the length of the solid wood frame where it is located;

[0043] Several layers of core boards 3 are provided inside the photo frame body 1 , and one side of the core boards 3 is in contact with the exhibits.

[0044] First, the mortise and tenon structure 2 in this embodiment, with its unique interlocking design—namely, the interference fit between the mortise groove 211 of the first joint 21 and the tenon 221 of the second joint 22—achieves a stable and tight connection between the solid wood frame edges. This connection method helps reduce the risk of loosening due to long-term use or external forces, and also significantly improves the overall load-bearing capacity and stability of the photo frame, ensuring the safe display of exhibits.

[0045] Secondly, although the mortise and tenon structure 2 also emphasizes the environmentally friendly concept of no nails and no glue, compared with the complex processing of the traditional dovetail structure, it is easier to align and assemble the edges of the solid wood frames, especially while ensuring the structural strength, it simplifies the structure.

[0046] Furthermore, the innovative design of the mounting opening 111 on at least one side of the solid wood frame of the photo frame body 1 greatly facilitates the removal and placement of exhibits, improving practicality and making the maintenance and replacement of exhibits extremely convenient. Exhibits can be easily replaced without disassembling the entire photo frame structure, making this design particularly suitable for museums, galleries, and other places where exhibits need to be regularly replaced.

[0047] Specifically, the solid wood frame edges on two adjacent sides are spliced, wherein the two ends of the solid wood frame edge on one side are respectively provided with the first splicing structure, and the two ends of the solid wood frame edge on the other side are respectively provided with the second splicing structure.

[0048] Specifically, the photo frame body 1 includes a first frame side 11, a second frame side 12, a third frame side 13, and a fourth frame side 14 that are sequentially spliced ​​together; wherein the first frame side 11 is disposed opposite to the third frame side 13, and the second frame side 12 is disposed opposite to the fourth frame side 14, and the embedding opening 111 is disposed on the first frame side 11;

[0049] It should be noted that since the embedding opening 111 is an opening, in order to prevent impurities such as paper scraps and dust from entering through the embedding opening 111, the first frame edge 11 can generally be set as the bottom of the photo frame body 1. When the exhibit is installed, the photo frame body 1 stands on a plane that closes the embedding opening 111.

[0050] The second splicing structures are respectively provided at both ends of the first frame side 11 and the third frame side 13 , and the first splicing structures are respectively provided at both ends of the second frame side 12 and the fourth frame side 14 .

[0051] Specifically, the embedding opening 111 is in the shape of an elongated strip, with its front and rear ends extending back to each other and not exceeding the tenons 221 at both ends.

[0052] Specifically, the middle portion of the first splicing portion 21 is provided with the tongue groove 211 , and the middle portion of the second splicing portion 22 is provided with the tongue 221 .

[0053] The first joint portion 21 has wedge openings 212 on the left and right sides of the mortise 211, and the second joint portion 22 has wedge portions 222 protruding on the left and right sides of the tenon 221. When the first joint portion 21 and the second joint portion 22 are joined, the inclined surfaces of the wedge portions 222 fit in with the inclined surfaces of the wedge openings 212.

[0054] More specifically, during the assembly of the first joint portion 21 and the second joint portion 22, the tenon 221 is first aligned with the tenon groove 211, and then the second joint portion 22 is pushed toward the tenon groove 211. The inclined surface of the wedge portion 222 will slide smoothly along the inclined surface of the wedge opening 212 until the tenon 221 is completely engaged with the tenon groove 211. At this time, the inclined surface of the wedge portion 222 will also be completely in contact with the inclined surface of the wedge opening 212.

[0055] It should be noted that when the tenon 221 is fully inserted into the mortise 211 and the inclined surface of the wedge portion 222 is fully fitted with the inclined surface of the wedge opening 212, a stable mechanical connection is formed. This structure not only enhances the strength of the connection, but also improves the overall stability.

[0056] Specifically, the shape of the tenon groove 211 and the tenon 221 is rectangular or square, which is conducive to reducing the difficulty of manufacturing process and production cost;

[0057] The width of the solid wood frame is 3.5-5.0 cm, and 4.0 cm is preferred in this embodiment;

[0058] Specifically, the embedding opening 111 is located in the middle of the solid wood frame and passes through the upper and lower sides of the solid wood frame, providing more functionality for the solid wood frame. For example, elements such as glass and decorative strips can be embedded to enrich the design and practicality of the solid wood frame.

[0059] It should be noted that if the end of the solid wood frame edge adopts a traditional dovetail structure, it will be more difficult to make the dovetail, and the width of the solid wood frame edge in this embodiment is relatively small, only 4 cm. The width occupied by the traditional dovetail is relatively large, which will result in insufficient distance in the middle of the solid wood frame edge to open the embedding opening 111; in addition, compared with the traditional dovetail structure, the mortise and tenon structure 2 of this embodiment realizes a fast and stable assembly process through the cooperation of the mortise 211 and the tenon 221, and the oblique splicing of the wedge mouth 212 and the wedge portion 222. This design simplifies the assembly steps and improves assembly efficiency.

[0060] Specifically, the inner sides of the remaining solid wood frame edges that are not provided with the embedding opening 111 are all provided with grooves, and each of the grooves is provided along the length of the corresponding solid wood frame edge; the embedding opening 111 is communicated with each of the grooves;

[0061] Specifically, the grooves arranged along the lateral direction of the photo frame body 1 are guide grooves 15, and the grooves arranged along the transverse direction of the photo frame body 1 are limit grooves;

[0062] In this embodiment, the guide groove 15 provides a clear insertion path for the exhibit. When the exhibit enters from the insertion opening 111, the guide groove 15 can guide the exhibit to move smoothly along a predetermined direction, ensuring that the exhibit can accurately reach the predetermined position.

[0063] The setting of the limiting groove can limit the further movement of the exhibit, thereby fixing the position of the exhibit in the photo frame body 1, thereby ensuring that the exhibit will not shake arbitrarily during the display process;

[0064] Specifically, in the same solid wood frame edge, the percentage of the depth of the groove to the thickness of the solid wood frame edge is in the range of 40%-50%, so as to ensure that the exhibits can be smoothly embedded in the photo frame body 1.

[0065] Specifically, at least two layers of core boards 3 are provided inside the photo frame body 1. A hollow space is formed between the two layers of core boards 3 for pressing the exhibits at the front and back to further ensure that the exhibits will not shake or fall off during the display process.

[0066] More specifically, the two core plates 3 are both transparent; the core plates 3 are glass plates or plastic plates; it should be noted that the arrangement of the two transparent core plates 3 is suitable for double-sided display of exhibits, such as double-sided embroidery works, etc.

[0067] Alternatively, one of the two core boards 3 is transparent. It should be noted that this single-sided transparent design is suitable for single-sided display of exhibits, such as Chinese paintings, calligraphy, etc.

[0068] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
