[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. 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 6-8As shown, the utility model provides an aluminum-wood composite picture frame corner fixing adjustment component, which is used for the aluminum-wood composite picture frame, including an angle fixing member 30 and two adjusting members 50, wherein the angle fixing member 30 is used to be installed at the corner joint of the aluminum-wood composite picture frame, and the angle fixing member 30 has an angle fixing plate 31 connected to form a right angle shape, and the two sides of the angle fixing plate 31 are respectively provided with vertically inward angle support blocks 32, and the two angle support blocks 32 are vertically connected to the angle fixing plate 31, and the two sides of the angle support blocks at the connection position are respectively provided with concave sliding grooves 55, so that the angle fixing plate 31 can be installed at the edge of the aluminum-wood alloy picture frame. The adjusting member 50 includes an adjusting plate 51 and an adjusting block 52, the adjusting plate 51 and the adjusting block 52 are vertically connected, and an inwardly concave sliding groove 55 is provided on the adjusting block 52 at the connection position, so that the adjusting member 50 can be installed in the second embedded connecting structure 11b of the aluminum-wood alloy picture frame frame structure, so that it can slide in the second embedded connecting structure 11b; wherein, the adjusting block 52 is provided with a transverse screw hole, and the tightening screw passes through the screw hole and is tightened on the corner support block 32 of the corner fixing member.

[0031] When in use, the two frames of the aluminum-wood composite picture frame are butted together, and the two adjusting members 50 are first inserted into the second embedded connection structures 11b of the two frames respectively, and then the corner fixing members are simultaneously inserted into the second embedded connection structures 11b of the two frames; a certain length is reserved between the adjusting member 50 and the end of the frame, so that after the corner fixing member 50 is inserted into the second embedded connection structure 11b, there is still a certain margin for the adjusting member 50 to adjust the operation. Then, the vertical reference of the two frames is determined by a tool such as a square ruler, and the tightening screws on the two adjusting members 50 are adjusted to fine-tune the position of the corner fixing member 50 so that the two frames remain in a vertical state, and then the locking screws on the corner fixing member 30 are tightened to fix the position of the corner fixing member 30.

[0032] The adjusting plate 51 is provided with a screw hole for installing a locking screw, and a locking block 511 is installed at the end of the locking screw. The locking block 511 can be twisted by the locking screw to be supported on the two long side plates 111 of the aluminum-wood composite picture frame frame structure.

[0033] The angle support block 32 is at the same height as the adjustment block 52. The two structural blocks are at the same height, so that the supporting force can be better transmitted between the two.

[0034] The corner fixing plate 31 is provided with screw holes for installing tightening screws, and the tightening screws can be supported on the horizontal clamping plate 112 of the aluminum-wood alloy picture frame.

[0035] The inner corner of the corner fixing plate 31 is also provided with a reinforcing rib plate 33. The reinforcing rib plate 33 can improve the anti-deformation ability of the right-angle bend of the entire corner fixing member 30, thereby making the structure stable and reducing stress concentration.

[0036] The corner fixing member 30 is a symmetrical structure, specifically, an axisymmetric structure with respect to the central inclined line of 45 degrees relative to the right angle end. The symmetrical structure allows the corner fixing member 30 to be installed in two directions without being restricted by the structure.

[0037] The aluminum-wood composite picture frame corner fixing and adjusting component provided by the utility model can complete the frame connection of the aluminum-wood composite picture frame by cooperating with the fixing part and the adjusting part, and can fine-tune the connection position and angle of the frame, so that the shape and size of the aluminum-wood composite picture frame are more standardized, thereby improving the manufacturing accuracy and connection strength of the aluminum-wood composite picture frame.

[0038] like Figure 1-5 As 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 component, so as to assist the corner connecting piece 20 in supporting, so that the supporting structure is stable and not easily deformed.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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 smooth and convenient connection.

[0045] 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.

[0046] like Figure 5 As shown, a circular chamfered hole 21 is provided at the inner corner of the corner connecting piece 20.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.
