[0002] The canvas of an oil painting needs to be fixed on a frame. The frame is usually made of wood, but the wood structure is easily deformed by moisture, and when the frame needs to be moved or replaced, the canvas needs to be removed from the frame and then nailed back. At this time, the process of removing and reinstalling the wooden frame can easily cause the frame to crack and be damaged.

[0003] Aluminum alloy picture frames are currently available, but they are not easy to anchor and the overall cost of aluminum alloy picture frames is relatively high, resulting in reduced practicality.

[0004] Patent CN220275317U also discloses a wood-aluminum alloy composite picture frame, which is formed by combining wood and aluminum alloy. Its structure adopts a single-side slotting method to facilitate the connection and fixation of the corner connector. Such a structure reduces the strength of the picture frame on the slotted side, and the single-side corner connector connection method also makes the other side structure unstable. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the utility model is to provide an aluminum-wood composite picture frame frame structure and a picture frame, so as to solve the problem that the existing aluminum-wood composite alloy picture frame has a single-side groove, which leads to a decrease in structural strength.

[0006] In order to solve the above technical problems, the utility model provides an aluminum-wood composite picture frame frame structure, including an aluminum alloy profile and a wood strip, wherein the aluminum alloy profile adopts an integrated structure and is in the shape of a long strip, the cross-section of the aluminum alloy profile is rectangular, a first embedded connection structure is provided on one side of the aluminum alloy profile, and a second embedded connection structure is provided on the other side, and a rectangular embedded connection frame is provided between the two embedded connection structures, and an embedded groove is provided in the embedded connection frame to install a corner connecting piece; wherein a longitudinal slot is provided at the connecting end of the wood strip, and the connecting end of the wood strip is embedded and connected in the first embedded connection structure, and the slot of the wood strip is engaged with the first embedded connection structure.

[0007] The aluminum alloy profile comprises two long side plates and two transverse clamping plates connecting the two long side plates, and two ends of the two transverse clamping plates are connected to the long side plates to form the embedded connection frame.

[0008] Two longitudinal clamping strips are arranged on the inner surface of each transverse clamping plate, and each longitudinal clamping strip forms a clamping groove with its adjacent long side plate so that the corner connecting piece can be inserted.

[0009] A transverse clamping strip is provided on the inner side of the end of each long side plate, and the transverse clamping strip is clamped with the clamping slot.

[0010] The cross section of the wood strip is an L-shaped structure.

[0011] The corner connecting piece is in a right-angle shape formed by connecting two right-angle sides.

[0012] The end of the right-angle side is an arc structure.

[0013] The inner side of the right-angle side shrinks inwards to form an inclined angle, and the width at the root of the right-angle side is equal, and the distance between the two horizontal clamping plates is equal, so that it can be inserted into the embedded connection frame.

[0014] The inner corners of the corner connecting pieces are provided with circular chamfered holes.

[0015] There are two corner connecting pieces, which are inserted side by side into two sides of the embedded connecting frame.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1-5As shown, the utility model provides an aluminum-wood composite picture frame frame structure 10, including an aluminum alloy profile 11 and a wood strip 12, wherein the aluminum alloy profile 11 adopts an integrated structure and is in the shape of a long strip, the cross-section of the aluminum alloy profile 11 is rectangular, a first embedded connection structure 11a is provided on one side of the aluminum alloy profile 11, and a second embedded connection structure 11b is provided on the other side, and a rectangular embedded connection frame 11c is provided between the two embedded connection structures, and an embedded groove is provided in the embedded connection frame 11c to install a corner connecting piece 20; wherein, a longitudinal card groove 121 is opened at the connecting end of the wood strip 12, and the connecting end of the wood strip 12 is embedded and connected in the first embedded connection structure 11a, and the card groove 121 of the wood strip 12 is card-engaged with the first embedded connection structure 11a. In this embodiment, the aluminum alloy profile 11 is the main load-bearing device, which can fix the wood strips 12 and provide a supporting foundation for the wood strips; the aluminum alloy profile 11 itself has a stable structure and is not easily deformed, so it can resist the pulling force of the canvas on the frame. Compared with the existing aluminum alloy composite structure picture frame, the aluminum-wood composite picture frame frame structure 10 provided in this embodiment has better structural integrity, so that the corner connecting piece 20 of the picture frame can be directly inserted into the embedded connecting frame 11c, thereby fixing the corners of the picture frame; the second embedded connecting structure 11b in this embodiment is used to connect with the corner fixing adjustment module, so as to assist the corner connecting piece 20 in supporting, so that the supporting structure is stable and not easily deformed.

[0031] The aluminum alloy profile 11 includes two long side plates 111 and two transverse clamping plates 112 connecting the two long side plates 111. The two ends of the two transverse clamping plates 112 are connected to the long side plates 111, thereby forming the embedded connection frame 11c. The main structure of the aluminum alloy profile 11 in this embodiment is a rectangular structure composed of two long side plates 111 and two transverse clamping plates 112, wherein the two long side plates 111 define the length and external shape of the entire aluminum alloy profile 11, and the transverse clamping plates 112 provide support for the two long side plates 111 from the inside, so that the entire aluminum alloy profile 11 is fixed and not easy to change.

[0032] Two longitudinal clips 1121 are provided on the inner surface of each of the transverse clips 112, and each longitudinal clip 1121 forms a clamping groove 1122 with the adjacent long side plate 111, so that the corner connecting piece 20 can be inserted. The two longitudinal clips 1121 respectively maintain a distance from the long side plate 111 on one side, and the distance is equal to the thickness of the corner connecting piece 20, so that the corner connecting piece 20 can be inserted into the clamping groove 1122. At this time, the height of the clamping groove 1122 is limited by the two transverse clips 112, and the distance between the two transverse clips 112 is also equal to the width of the right angle position of the corner connecting piece 20, so that the corner connecting piece 20 can be just inserted into the clamping groove 1122.

[0033] A transverse clamping strip 1111 is provided on the inner side of the end of each long side plate 111, and the transverse clamping strip 1111 is clamped with the clamping groove 121. The transverse clamping strip 1111 protrudes inwardly, so that the transverse clamping strips 1111 on the inner sides of the two long side plates 111 are just opposite to each other, so that when connected with the wood strip 12, they are just clamped into the clamping groove 121 on the wood strip 12, so that the wood strip 12 is connected and fixed to the aluminum alloy profile, and is not easy to deform.

[0034] The cross section of the wood strip 12 is an L-shaped structure. One end of the L-shaped wood strip 12 is used for fixed connection with the first embedded connection structure 11a, and the other end is used for fixed connection with the canvas, so that the canvas can be supported on the wood strip 12, but not directly supported on the aluminum alloy profile 11, and will not contact the aluminum alloy profile 11, and the aluminum alloy material cannot be seen from the outside, giving users a better sense of traditional quality.

[0035] like Figure 5 As shown, the corner connecting piece 20 is a right-angle shape formed by connecting two right-angle sides, so that it can be inserted and fixed to the two aluminum-wood composite picture frame frame structures of the picture frame.

[0036] The end of the right-angled side is an arc structure, which can guide the corner connecting piece 20 to be inserted into the clamping groove 1122 in the embedded connecting frame 11c of the aluminum alloy profile 11. The arc structure avoids stress contact with the clamping groove 1122 during installation, ensuring a smooth and convenient connection.

[0037] The inner side of the right-angle side shrinks inwards to form an inclined angle, and the width at the root of the right-angle side is equal, and the distance between the two horizontal clamping plates is equal, so that it can be inserted into the embedded connection frame.

[0038] like Figure 5 As shown, a circular chamfered hole 21 is provided at the inner corner of the corner connecting piece 20.

[0039] The two corner connecting pieces 5 are inserted side by side into the clamping grooves 1122 on both sides of the embedded connecting frame, so that they can be riveted and supported through two supporting points to form an aluminum-wood composite picture frame frame structure.

[0040] The utility model also provides a picture frame, combined with Figure 4 At the corner position shown, the picture frame includes the above-mentioned aluminum-wood composite picture frame frame structure 10 and the right-angle connecting piece 20, wherein the aluminum-wood composite picture frame frame structure 10 has four, which are spliced ​​end to end to form a square structure, and the connection position between two adjacent aluminum-wood composite picture frame frame structures 10 is connected by two right-angle connecting pieces 20.

[0041] The aluminum-wood composite picture frame frame structure and the picture frame provided by the utility model can improve the structural strength of the picture frame. Compared with the existing composite picture frame structure that adopts a single-side slot connection, the utility model adopts an embedded insertion structure to ensure the integrity of the picture frame structure, and does not need to be slotted on the side, but only needs to be connected at the position of the inner corner; and the embedded structure design of the aluminum alloy profile is reasonably utilized, and the corner connecting piece is inserted into the embedded structure, so that the connection structure is stable and not easy to deform.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
