Description

Technical Field

[0001] The utility model relates to the technical field of picture frames, in particular to a wooden picture frame with a mortise and tenon structure. Background Art

[0002] A picture frame is a commonly used structure in daily life. In the actual processing of wooden picture frames, some use the mortise and tenon structure for fixation. For example, a picture frame disclosed in Chinese Patent CN214905636U includes a frame body, which is a quadrilateral with a central hole in the center. The frame body is composed of an upper frame body and a lower frame body. The width of the upper frame body is smaller than that of the lower frame body, and a drawing paper slot is provided on the upper frame body or at the connection between the upper frame body and the lower frame body. The drawing paper slot is for the insertion of each side of the drawing paper. A hook baffle is provided on the inner wall of the lower frame body, and the hook baffle is provided on the entire inner wall of the lower frame body, and there is a distance between the hook baffle and the drawing paper slot.

[0003] Among them, mortise and tenon structures are processed at both ends of the border rod body. The head and tail ends of the border rod body need to be inserted into the other border rod bodies. After the connection of adjacent rod bodies, there will be an inclined splicing line, which will affect the overall aesthetics. With the continuous development and change of the market, picture frames in a simple style are more and more popular among the masses. Although the number of people who like the mortise and tenon structure is large, a considerable number of people who pursue the simple style give up because there are obvious splicing line marks on the display surface. In addition, most of the existing picture frames with mortise and tenon structures only use a single-layer border structure, and the drawing board only uses a relatively simple clamping and connecting structure on the inner side, resulting in inconvenient operation for fixing the drawing board in the central hole during the mortise and tenon splicing of the frame body. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wooden picture frame with a mortise and tenon structure, which helps to solve the problems that some existing picture frames with mortise and tenon structures use a single-layer border structure, the exposed splicing lines affect the aesthetics, and it is inconvenient to fix the inner drawing board.

[0005] In order to achieve the above purpose, the utility model adopts such a technical solution:

[0006] A wooden picture frame with a mortise and tenon structure includes a main body and a panel made of wood. The main body is composed of several splicing strips to form a frame structure. The panel is an integral structure and is consistent with the splicing contour of the main body. The adjacent splicing strips are connected by a mortise and tenon structure, and the panel and the main body are connected by a concave-convex clamping structure; a first sunk platform is provided on one side of the main body close to the panel, and a second sunk platform is provided on one side of the panel close to the main body. The first sunk platform and the second sunk platform have the same contour, and a cavity for accommodating a painting is formed after the main body and the panel are spliced. The panel forms a display window in the central area on the front side of the cavity.

[0007] On the basis of the above technical solution, the outer side surface of the panel is a flat end face.

[0008] On the basis of the above technical solution, the main body is a rectangular frame structure, which is composed of 4 mutually perpendicular splicing strips; both ends of the splicing strips are provided with 45° oblique cuts on the front and rear sides, and slots and inserts are arranged in a staggered distribution before and after between the oblique cuts. The inserts are exposed outside the end face of the oblique cut, the slots are recessed inside the end face of the oblique cut, and the outer contour of the insert and the inner contour of the slot are in a concave-convex complementary structure. When adjacent splicing strips are spliced, the insert can be embedded into the corresponding slot on another splicing strip and connected in an interference fit manner.

[0009] On the basis of the above technical solution, a first cut groove is provided at the inner end of the front side of the splicing strip, and the first cut grooves on each splicing strip form the first sunk platform after splicing.

[0010] On the basis of the above technical solution, a second cut groove is provided at the center position of the splicing strip where the first cut groove is located, and the first cut groove and the second cut groove form a "T"-shaped sunk platform structure at the bottom of the front side of the splicing strip.

[0011] On the basis of the above technical solution, a flange adapted to the second cut groove is provided on the back surface of the panel. After the main body and the panel are spliced, the flange can be embedded into the second cut groove and connected in an interference fit manner.

[0012] On the basis of the above technical solution, a plurality of third cut grooves are provided at intervals before and after on the left and right side walls of the second cut groove, and the third cut grooves form a plurality of thin sheet structures on the end faces of the left and right side walls of the second cut groove.

[0013] On the basis of the above technical solution, a hanging structure is provided at the top of the main body.

[0014] Compared with the prior art, the utility model has at least the following advantages:

[0015] 1. The utility model improves the aesthetics. By using the panel as a decorative part on the front of the main body and combining the mortise and tenon structure and the concave-convex clamping structure, the exposure of the splicing lines is avoided, and the overall aesthetics of the picture frame is improved.

[0016] 2. The utility model optimizes the constraint structure of the painting. By setting the first sunk platform and the second sunk platform to form a cavity, the assembly space of the painting is improved, and the front and rear clamping structure is used to ensure the assembly stability of the painting and the convenience during installation.

[0029] Please refer to Figures 1 to 7, this embodiment discloses a wood picture frame with a mortise and tenon structure, aiming to solve the problems in the prior art that the spliced joints of the mortise and tenon picture frame with a single-layer border structure are exposed, affecting the aesthetics, and the inner drawing board is not convenient to fix.

[0030] This picture frame specifically includes a main body 1 and a panel 2 made of wood (pine wood is used in this embodiment, and the surface is polished and deburred). The main body 1 is composed of a plurality of splicing strips 3 to form a frame structure, the panel 2 is an integral structure and has the same splicing contour as the main body 1, and adjacent splicing strips 3 are connected by a mortise and tenon structure, and the panel 2 and the main body 1 are connected by a concave-convex clamping structure. Specifically, as shown in Figure 2 and Figure 3 , the main body 1 is a rectangular border structure and is composed of 4 mutually perpendicular splicing strips 3.

[0031] Furthermore, the mortise and tenon structure of adjacent splicing strips 3 is specifically as follows: both ends of the splicing strip 3 are provided with 45° inclined cuts 31 on the front and back sides, there are slots 32 and inserts 33 distributed in a front-back staggered manner between the inclined cuts 31, the insert 33 is exposed outside the end face of the inclined cut 31, the slot 32 is recessed inside the end face of the inclined cut 31, the outer contour of the insert 33 and the inner contour of the slot 32 are in a concave-convex complementary structure, and the insert 33 can be embedded into the corresponding slot 32 on another splicing strip 3 when adjacent splicing strips 3 are spliced, and the connection is realized in an interference fit manner. It should be noted that the slots 32 and inserts 33 on the left and right sides of the same splicing strip 3 are arranged in a front-back staggered manner. For example, the slot 32 on the left side is in front of the insert 33 on that side, and the slot 32 on the right side is behind the insert 33 on that side.

[0032] During specific use, the 4 identical splicing strips 3 as shown in Figure 2 are butt-jointed end to end in a pairwise perpendicular manner, and are spliced into the main body 1 in Figure 3 by using the mortise and tenon structure.

[0033] Continuing to refer to the content in Figure 3 , a first sunk platform 4 is provided on one side of the main body 1 close to the panel 2, and in combination with Figure 6 , a second sunk platform 5 is provided on one side of the panel 2 close to the main body 1. The first sunk platform 4 and the second sunk platform 5 have the same contour, and a cavity for accommodating the painting is formed after the main body 1 and the panel 2 are spliced (as shown in Figure 7 ), and a display window 7 is formed in the central area on the front side of the cavity of the panel 2 (as shown in Figure 1 ). In this embodiment, the painting is specifically an oil painting product, and the oil painting cloth of the oil painting product is fixed on the inner frame body. When the oil painting with the inner frame body is installed, it is directly placed in the first sunk platform 4, and with the splicing of the panel 2, a fixing structure of front and back clamping is formed by using the second sunk platform 5.

[0034] In this embodiment, the outer side surface of the panel 2 is a flat end face, which can form a simple-style decorative part structure on the front of the main body 1 to cover the splicing pattern on the main body 1, so that the front of the picture frame has better simplicity and beauty.

[0035] As Figure 3 and Figure 4 shown, a first cutting groove 34 is provided at the inner end of the front surface of the splicing strip 3, and the first cutting grooves 34 on each splicing strip 3 form the first sunken platform 4 after splicing.

[0036] Furthermore, a second cutting groove 35 is provided at the center position of the first cutting groove 34 of the splicing strip 3, and the first cutting groove 34 and the second cutting groove 35 form a "T"-shaped sunken platform structure at the bottom of the front surface of the splicing strip 3. Combining Figure 6 , a flange 21 adapted to the second cutting groove 35 is provided on the back surface of the panel 2. After the main body 1 and the panel 2 are spliced, the flange 21 can be inserted into the second cutting groove 35 and connected in an interference fit manner.

[0037] In another embodiment, in order to improve the splicing stability between the panel 2 and the main body 1, as Figure 8 shown, a plurality of third cutting grooves 36 are provided on the left and right side walls of the second cutting groove 35 and are distributed at intervals in the front and back directions. The third cutting grooves 36 form a plurality of thin sheet structures on the end faces of the left and right side walls of the second cutting groove 35. When the flange 21 is inserted into the second cutting groove 35, these thin sheet structures will be squeezed by the left and right side walls of the flange 21 and will generate corresponding inclined deformation after being squeezed. After the panel 2 and the main body 1 are strongly pressed and spliced together, these thin sheet structures will increase the friction coefficient between the side wall of the flange 21 and the side wall of the second cutting groove 35 due to deformation, which is beneficial to preventing the panel 2 from falling off.

[0038] In yet another embodiment, combining Figure 9 shown, a hanging structure is provided at the top of the main body 1. The hanging structure includes a hanging member 6 embedded in the top of the main body 1. The hanging member 6 is a component structure made of aluminum alloy material. A cross beam 61 is provided at the center position of its top, and a rope passing groove 62 is provided below the cross beam 61. The rope passing groove 62 forms openings on the left and right sides of the cross beam 61 to facilitate the passing of a rope. When in use, a rope of an appropriate length is passed through the hanging member 6, and then the rope is hung on a nail or a hook on the wall.
