Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy frame technology, and more specifically, it relates to a serrated anti-loosening aluminum alloy frame. Background Technology

[0002] Aluminum alloy frames are a common type of aluminum alloy product, characterized by their lightweight, high strength, and corrosion resistance. Their main applications include picture frames, advertising displays, document frames, poster frames, and door and window frames. When building door and window openings are constructed with non-standard dimensions, installing subframes allows for more precise measurement of the door and window manufacturing dimensions. Installing subframes on aluminum alloy windows ensures that the manufacturing dimensions of the doors and windows are accurate, facilitating installation and improving safety. Furthermore, subframes make it easier to control the installation quality and reduce the expansion and contraction caused by thermal changes in plastic doors and windows.

[0003] Its drawback is that, since the width of the aluminum alloy frame is fixed, the glass or wooden door panels inside the frame often have an error in width with the aluminum alloy frame during the manufacturing process, which leads to the glass or wooden door panels becoming loose. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a serrated anti-loosening aluminum alloy frame, which solves the problem of loose glass or wooden door panels by providing a central column inside the aluminum alloy frame groove.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sawtooth anti-loosening aluminum alloy frame, comprising two pairs of mutually symmetrical alloy strips and corner pieces, wherein adjacent alloy strips are perpendicular to each other and the ends are all cut at 45° angles, and the cross section of the alloy strip from top to bottom includes an upper top surface, a first through hole, a first sawtooth placement groove, a second through hole, a second sawtooth placement groove and a lower bottom surface, wherein the first sawtooth placement groove and the second sawtooth placement groove are both used to place wooden boards or glass boards for doors and windows.

[0006] Preferably, the first through hole is formed by the upper top surface and the first stop block, and the second through hole is formed by the "J"-shaped panel and the second stop block.

[0007] More preferably, the first corner piece and the second corner piece are both integrally formed connecting pieces that are perpendicular to each other, and are provided with a top bending head.

[0008] More preferably, at the connection points of adjacent alloy strips, the two connecting pieces of the first corner piece are respectively inserted into the through hole, and the two connecting pieces of the second corner piece are respectively inserted into the second stop block.

[0009] The principle of this invention is as follows: the edge of the glass or wooden door panel is cut into a shape that fits into the center post with the second through hole. When the width of the glass or wooden door panel is less than the first or second sawtooth groove, the fit of the center post ensures that the glass or wooden door panel will not loosen. The excess part can be filled with the appropriate filler glue.

[0010] In summary, this utility model has the following beneficial effects:

[0011] Firstly, since it is inconvenient to insert the first corner piece when its width is equal to the width of the first through hole, the width of the first corner piece is smaller than the width of the first through hole. Therefore, a bending head is set to fill the gap when its width is insufficient. The second corner piece is for the same reason.

[0012] Secondly, two corner pieces and two through holes are provided to ensure the stability of the product at corners from a three-dimensional perspective. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and are not intended to indicate or explicitly state that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or explicitly suggesting relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] See details Figure 1-6 A sawtooth anti-loosening aluminum alloy frame includes two pairs of symmetrical alloy strips and corner pieces. The adjacent alloy strips are perpendicular to each other and the ends are all cut at 45°. The cross-section of the alloy strip from top to bottom includes an upper top surface 1, a first through hole 2, a first sawtooth placement groove 3, a central column with a second through hole 4, a second sawtooth placement groove 5, and a lower bottom surface 6. The first sawtooth placement groove 3 and the second sawtooth placement groove 5 are both used to place wooden boards or glass boards for doors and windows.

[0025] Specifically, the first through hole 2 is composed of an upper top surface 1 and a first stop block 7, and the central column is composed of a "J"-shaped panel 8 and a second stop block 9.

[0026] Specifically, the first corner piece 10 and the second corner piece 11 are both integrally formed connecting pieces that are perpendicular to each other, and are provided with a top bending head 12.

[0027] Specifically, at the connection of adjacent alloy strips, the two connecting pieces of the first corner piece 10 are inserted into the through holes, and the two connecting pieces of the second corner piece 11 are inserted into the second stop block.

[0028] The principle of this embodiment is as follows: the edge of the glass or wooden door panel is cut into a shape that fits with the central post with the second through hole 4. When the width of the glass or wooden door panel is less than the first sawtooth placement groove 3 or the second sawtooth placement groove 5, the fit of the central post ensures that the glass or wooden door panel will not be loose. The excess part can be filled with the appropriate filler glue.

[0029] Since it is inconvenient to insert the first corner piece when its width is equal to the width of the first through hole 2, the width of the first corner piece is smaller than the width of the first through hole 2. Therefore, the bending head 12 is set to fill the gap when its width is insufficient. The second corner piece is for the same reason.

[0030] The inclusion of two corner pieces and two through holes ensures the stability of the product at corners from a three-dimensional perspective.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
