[0046] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0047] According to one embodiment of this application, a keel is provided, see [link to embodiment]. Figure 1 The keel includes:

[0048] The first side 1, the second side 2, and the third side 3 are connected. One end of the first side 1 is connected to the second side 2 through the first slot 6, and the other end of the first side 1 is connected to the third side 3 through the second slot 7. The length of the second side 2 is equal to the length of the third side 3, and the difference between the length of the first side 1 and the length of the second side 2 is 0 to 10 mm.

[0049] The first bending part 4 and the second bending part 5 are connected to the second side 2 through the third slot 8, and the second bending part 5 is connected to the third side 3 through the fourth slot 9; an opening 10 is formed between the first bending part 4 and the second bending part 5, and the opening 10 is disposed opposite to the first side 1.

[0050] In the above embodiments, the first side 1, the second side 2, and the third side 3 are used to form the supporting edges of the keel. The keel can be connected to the wall through any one or any two supporting edges to install the keel on the wall, which facilitates subsequent decoration of the wall through the keel; or, the keel can also be connected to other keels through any one, any two, or any three supporting edges to install the keels together, which facilitates subsequent decoration through the keel.

[0051] In the above embodiment, one end of the first side 1 is connected to the second side 2 through the first slot 6, and the other end of the first side 1 is connected to the third side 3 through the second slot 7, so that the first side 1, the second side 2 and the third side 3 can form an open keel with an opening 10 on one side. The open keel can meet the needs of mass production in the factory and improve the standardization of the keel; on the other hand, it can also improve the transportation and modular assembly efficiency of the keel and realize more efficient installation of the keel; furthermore, it can also provide an installation area for pipelines, making the keel more practical.

[0052] In the above embodiment, after the first side 1, the second side 2 and the third side 3 are connected to each other, the first side 1 is arranged opposite to the opening 10, and the second side 2 and the third side 3 are arranged opposite to each other.

[0053] The length of the first side 1 is L1, the length of the second side 2 is L2, the length of the third side 3 is L3, and the length of the opening 10 is L4. The length L2 of the second side 2 is equal to the length L3 of the third side 3, and the difference between the length L1 of the first side 1 and the length L2 of the second side 2 is 0-10 mm. Since the length L2 of the second side 2 is equal to the length L3 of the third side 3, the difference between the length L1 of the first side 1 and the length L3 of the third side 3 is also 0-10 mm.

[0054] Therefore, as Figure 1 As shown, the dimensions of the first side 1, the second side 2, and the third side 3 are designed to make the overall shape of the keel approach a square. This allows the keel to withstand greater external forces after decoration, effectively reducing deformation caused by stress and improving its resistance to deformation. Furthermore, since the first side 1 and the second side 2 are connected by the first slot 6, and the first side 1 and the third side 3 are connected by the second slot 7, when the first side 1, the second side 2, and the third side 3 are subjected to significant external forces, these forces can be transferred to the first slot 6 and the second slot 7 for absorption. In other words, the first slot 6 and the second slot 7 reinforce the structure of the keel, further improving its resistance to deformation.

[0055] In addition, the opening 10 of the keel is provided with a first bend 4 and a second bend 5. The first bend and the second bend can enhance the external force that the opening 10 of the keel can withstand, and prevent the second side 2 and the third side 3 from moving towards each other and causing the keel to deform.

[0056] A third slot 8 is provided between the first bending part 4 and the second side 2, and a fourth slot 9 is provided between the second bending part 5 and the third side 3. The third slot 8 and the fourth slot 9 can further absorb the external force borne by the second side 2 and the third side 3, making the keel more resistant to deformation.

[0057] In addition, the embodiment of this application, through the setting of the first slot 6, the second slot 7, the third slot 8 and the fourth slot 9, enables multiple keels to be connected by the snap-fit ​​between the corner piece and the slot, thereby further improving the installation efficiency of the keel.

[0058] In one embodiment, the length L1 of the first side 1 is greater than the length L4 of the opening 10.

[0059] Specifically, such as Figures 1 to 3 As shown, in this embodiment of the application, by setting the length L1 of the first side 1 to be greater than the length L4 of the opening 10, the deformation resistance of the second side 2 and the third side 3 is effectively enhanced, avoiding the situation where the opening 10 is too large, causing the side of the second side 2 away from the first side 1 to warp, or causing the side of the third side 3 away from the first side 1 to warp, thereby affecting the use effect of the keel.

[0060] In one embodiment, the first slot 6 is shaped like any one of C-shape, U-shape, or fan shape; and / or, the second slot 7 is shaped like any one of C-shape, U-shape, or fan shape; and / or, the third slot 8 is shaped like any one of C-shape, U-shape, or fan shape; and / or, the fourth slot 9 is shaped like any one of C-shape, U-shape, or fan shape.

[0061] Specifically, such as Figures 1 to 3 As shown, in this embodiment of the application, by setting the shape of the first slot 6, the second slot 7, the third slot 8, and the fourth slot 9 to any one of C-shaped, U-shaped, or fan-shaped, the keel has stronger resistance to deformation and the slots can better fit with the corner pieces, thereby effectively improving the installation efficiency of the keel.

[0062] In one embodiment, the first card slot 6, the second card slot 7, the third card slot 8, and the fourth card slot 9 are all fan-shaped; wherein the opening angle of the first card slot 6, the second card slot 7, the third card slot 8, and the fourth card slot 9 is 45°, and the radius dimensions of the first card slot 6, the second card slot 7, the third card slot 8, and the fourth card slot 9 are the same.

[0063] In the above embodiment, the opening angle of the first slot 6 is A, the opening angle of the second slot 7 is B, the opening angle of the third slot 8 is C, and the opening angle of the fourth slot 9 is D.

[0064] Therefore, as Figure 1 As shown, in this embodiment, by setting A, B, C, and D to all 45°, and by setting the radius dimensions of the first slot 6, the second slot 7, the third slot 8, and the fourth slot 9 to be the same, on the one hand, the first slot 6, the second slot 7, the third slot 8, and the fourth slot 9 have the same resistance to deformation, ensuring the stability and reliability of the keel; on the other hand, it also ensures that the keel and the corner piece are tightly engaged when they are fitted together, avoiding gaps between the keel and the corner piece that would result in poor installation of the keel.

[0065] In one embodiment, the length L5 of the first bend 4 is equal to the radius of the third slot 8; the length L6 of the second bend 5 is equal to the radius of the fourth slot 9.

[0066] Specifically, such as Figure 1 As shown, in this embodiment of the application, by setting the length L5 of the first bending portion 4 to be equal to the radius of the third slot 8, and setting the length L6 of the second bending portion 5 to be equal to the radius of the fourth slot 9, the keel has both strong resistance to deformation and lower manufacturing cost.

[0067] Of course, in other embodiments, while satisfying the deformation resistance of the keel, the length L5 of the first bending part 4 can be greater than or less than the radius of the third slot 8, and the length L6 of the second bending part 5 can be greater than or less than the radius of the fourth slot 9. Those skilled in the art can make the selection according to actual needs, and this application does not impose specific restrictions here.

[0068] In some embodiments, the first slot 6, the second slot 7, the third slot 8, and the fourth slot 9 are all C-shaped; wherein, the first slot 6 includes a first reinforcing part 601 and a second reinforcing part 602, the first reinforcing part 601 abuts against the first side 1, and the second reinforcing part 602 abuts against the second side 2; the second slot 7 includes a third reinforcing part 701 and a fourth reinforcing part 702, the third reinforcing part 701 abuts against the first side 1, and the fourth reinforcing part 702 abuts against the third side 3; the third slot 8 includes a fifth reinforcing part 801 and a sixth reinforcing part 802, the fifth reinforcing part 801 abuts against the first bent part 4, and the sixth reinforcing part 802 abuts against the second side 2; the fourth slot 9 includes a seventh reinforcing part 901 and an eighth reinforcing part 902, the seventh reinforcing part 901 abuts against the second bent part 5, and the eighth reinforcing part 902 abuts against the third side 3.

[0069] In the above embodiment, the first slot 6 includes a first reinforcing part 601, a second reinforcing part 602 and a first slot edge 603, with the first slot edge 603 disposed between the first reinforcing part 601 and the second reinforcing part 602.

[0070] Specifically, such as Figure 2 and Figure 3 As shown, one end of the first reinforcing part 601 is connected to the first side 1, and the other end of the first reinforcing part 601 is connected to the first slot edge 603; one end of the second reinforcing part 602 is connected to the second side 2, and the other end of the second reinforcing part 602 is connected to the first slot edge 603.

[0071] In this design, one side of the first reinforcing part 601 abuts against the first side 1, and one side of the second reinforcing part 602 abuts against the second side 2. On the one hand, by increasing the connection area, the connection effect between the first slot 6 and the first side 1, and between the first slot 6 and the second side 2 is enhanced, resulting in higher structural strength of the keel. On the other hand, it also allows the external force received by the first side 1 to be transmitted to the first slot 6 more quickly, and allows the external force received by the second side 2 to be transmitted to the first slot 6 more quickly, thereby effectively improving the deformation resistance of the keel.

[0072] In the above embodiment, the second slot 7 includes a third reinforcing part 701, a fourth reinforcing part 702, and a second slot edge 703, with the second slot edge 703 disposed between the third reinforcing part 701 and the fourth reinforcing part 702.

[0073] Specifically, such as Figure 2 and Figure 3 As shown, one end of the third reinforcing part 701 is connected to the first side 1, and the other end of the third reinforcing part 701 is connected to the second slot edge 703; one end of the fourth reinforcing part 702 is connected to the third side 3, and the other end of the fourth reinforcing part 702 is connected to the second slot edge 703.

[0074] Among them, one side of the third reinforcing part 701 abuts against the first side 1, and one side of the fourth reinforcing part 702 abuts against the third side 3. On the one hand, by increasing the connection area, the connection effect between the second slot 7 and the first side 1, and between the second slot 7 and the third side 3 is enhanced, making the structural strength of the keel higher. On the other hand, it also allows the external force received by the first side 1 to be transmitted to the second slot 7 more quickly, and allows the external force received by the third side 3 to be transmitted to the second slot 7 more quickly, thereby effectively improving the deformation resistance of the keel.

[0075] In the above embodiment, the third slot 8 includes a fifth reinforcing part 801, a sixth reinforcing part 802 and a third slot edge 803, with the third slot edge 803 disposed between the fifth reinforcing part 801 and the sixth reinforcing part 802.

[0076] Specifically, such as Figure 2 and Figure 3 As shown, one end of the fifth reinforcing part 801 is connected to the first bending part 4, and the other end of the fifth reinforcing part 801 is connected to the third slot edge 803; one end of the sixth reinforcing part 802 is connected to the second side edge 2, and the other end of the sixth reinforcing part 802 is connected to the third slot edge 803.

[0077] Among them, one side of the fifth reinforcing part 801 abuts against the first bending part 4, and one side of the sixth reinforcing part 802 abuts against the second side 2. On the one hand, by increasing the connection area, the connection effect between the third slot 8 and the first bending part 4, and between the third slot 8 and the second side 2 is enhanced, making the structural strength of the keel higher. On the other hand, it also allows the external force received by the first bending part 4 to be transmitted to the third slot 8 more quickly, and allows the external force received by the second side 2 to be transmitted to the third slot 8 more quickly, thereby effectively improving the deformation resistance of the keel.

[0078] In the above embodiment, the fourth slot 9 includes a seventh reinforcing part 901, an eighth reinforcing part 902 and a fourth slot edge 903, with the fourth slot edge 903 disposed between the seventh reinforcing part 901 and the eighth reinforcing part 902.

[0079] Specifically, such as Figure 2 and Figure 3 As shown, one end of the seventh reinforcing part 901 is connected to the second bending part 5, and the other end of the seventh reinforcing part 901 is connected to the fourth slot edge 903; one end of the eighth reinforcing part 902 is connected to the third side edge 3, and the other end of the eighth reinforcing part 902 is connected to the fourth slot edge 903.

[0080] Among them, one side of the seventh reinforcing part 901 abuts against the second bending part 5, and one side of the eighth reinforcing part 902 abuts against the third side 3. On the one hand, by increasing the connection area, the connection effect between the fourth slot 9 and the second bending part 5, and between the fourth slot 9 and the third side 3 is enhanced, making the structural strength of the keel higher. On the other hand, it also allows the external force received by the second bending part 5 to be transmitted to the fourth slot 9 more quickly, and allows the external force received by the third side 3 to be transmitted to the fourth slot 9 more quickly, thereby effectively improving the deformation resistance of the keel.

[0081] In one embodiment, the third slot 8 further includes a third slot edge 803, which is disposed between the fifth reinforcing part 801 and the sixth reinforcing part 802; the first bending part 4 includes a first sub-bending part 401 and a second sub-bending part 402, the first sub-bending part 401 abutting against the fifth reinforcing part 801, and the second sub-bending part 402 abutting against the third slot edge 803; the fourth slot 9 further includes a fourth slot edge 903, which is disposed between the seventh reinforcing part 901 and the eighth reinforcing part 902; the second bending part 5 includes a third sub-bending part 501 and a fourth sub-bending part 502, the third sub-bending part 501 abutting against the seventh reinforcing part 901, and the fourth sub-bending part 502 abutting against the fourth slot edge 903.

[0082] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment of the application, by setting the first sub-bending portion 401 to abut against the fifth reinforcing portion 801, and setting the second sub-bending portion 402 to abut against the third slot edge 803, the connection area between the first bending portion 4 and the third slot 8 is further increased, so that the first bending portion 4 and the third slot 8 have a better connection effect.

[0083] Furthermore, in this embodiment of the application, the connection area between the second bending portion 5 and the fourth slot can be further increased by setting the third sub-bending portion 501 to abut against the seventh reinforcing portion 901 and the fourth sub-bending portion 502 to abut against the fourth slot edge 903, so that the second bending portion 5 and the fourth slot have a better connection effect.

[0084] In one embodiment, the length of the first sub-bend 401 is less than the length of the second sub-bend 402; and the length of the third sub-bend 501 is less than the length of the fourth sub-bend 502.

[0085] In the above embodiment, the first sub-bending portion 401 and the third sub-bending portion 501 are arranged parallel to the first side 1, so that the first sub-bending portion 401 and the third sub-bending portion 501 can form a contact surface at the keel opening 10, thereby further enhancing the structural strength at the keel opening 10. The second sub-bending portion 402 and the fourth sub-bending portion 502 are arranged parallel to the second side 2 and the third side 3, so as to avoid deformation of the keel caused by the second side 2 and the third side 3 moving towards each other.

[0086] Among them, see Figure 2 and Figure 3 The length of the first sub-bending part 401 is smaller than that of the second sub-bending part 402, and the length of the third sub-bending part 501 is smaller than that of the fourth sub-bending part 502. This is to ensure the structural strength at the keel opening 10, and further avoid the problem of keel deformation caused by the opposite movement of the second side 2 and the third side 3, thereby improving the stability and reliability of the keel.

[0087] In one embodiment, the first slot 6 further includes a first slot edge 603, which is disposed between the first reinforcing part 601 and the second reinforcing part 602; the second slot 7 further includes a second slot edge 703, which is disposed between the third reinforcing part 701 and the fourth reinforcing part 702; the third slot 8 further includes a third slot edge 803, which is disposed between the fifth reinforcing part 801 and the sixth reinforcing part 802; the fourth slot 9 further includes a fourth slot edge 903, which is disposed between the seventh reinforcing part 901 and the eighth reinforcing part 902; wherein the first slot edge 603, the second slot edge 703, the third slot edge 803 and the fourth slot edge 903 are all L-shaped edges, and the lengths of the two sides of the L-shaped edge are equal.

[0088] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment of the application, by setting the first slot edge 603, the second slot edge 703, the third slot edge 803 and the fourth slot edge 903 to be L-shaped edges, on the one hand, the transition between each side and each bend of the keel is smoother, which facilitates the transmission of external forces on each side and each bend to the slot. On the other hand, it also facilitates the tight engagement between the keel and the corner piece when they are fitted together, avoiding the problem of poor installation effect of the keel due to gaps between the keel and the corner piece.

[0089] The two sides of the L-shaped edge are of equal length, which further enhances the keel's resistance to deformation and the tightness of the fit between the keel and the corner fittings.

[0090] In one embodiment, the length of the first side 1 is greater than or equal to the length of the second side 2.

[0091] Specifically, such as Figure 2 As shown, the length of the first side 1 can be greater than the length of the second side 2, so that the keel can be connected to the wall through the first side 1, ensuring the installation effect of the keel and the wall.

[0092] Of course, such as Figure 3 As shown, the length of the first side 1 can also be equal to the length of the second side 2, so that the structural strength of the first side 1, the second side 2 and the third side 3 are the same, ensuring the installation effect between the keels.

[0093] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
