Compared to straight, rigid panels, using rounded corners and transitions makes furniture more rounded and the home more welcoming and human-centered. Currently, most decorative panels are flat; creating rounded shapes requires standardized molds, resulting in long production cycles and limited flexibility in adjusting the curvature. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a non-standard decorative arc device.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A non-standard decorative arc device, including
[0006] A fixed frame, comprising a base plate on which a plurality of vertical plates are arranged, the vertical plates being parallel to each other, each vertical plate having a first arc segment at its first end, and a back plate connected to its second end; and
[0007] An adjusting plate is installed on the fixed frame. The first side surface of the adjusting plate is connected to the vertical plate. The first side surface is provided with a bending part corresponding to the first arc segment. By squeezing the bending part, the bending radius is adjusted so that it forms a second arc segment that matches the first arc segment.
[0008] Furthermore, the bending portion includes an arc plate, which has several bending grooves extending through it, with a protrusion formed between two adjacent bending grooves; when bending the arc plate, adjacent protrusions move closer to each other.
[0009] Furthermore, a mounting groove is provided through the first side surface of the adjusting plate, and the arc plate is disposed in the mounting groove; a fitting part is formed at the position of the mounting groove on the adjusting plate, and the arc plate and the fitting part constitute a second arc segment.
[0010] Furthermore, an adhesive layer is arranged in the mounting groove of the adjusting plate, and the side of the arc plate facing away from the bending groove is bonded to the adhesive layer.
[0011] Furthermore, the end of the adjusting plate is flush with the end face of the bottom plate of the fixed frame.
[0012] Furthermore, the vertical plate is fixedly installed on the bottom surface of the adjusting plate and / or the top wall of the base plate.
[0013] Furthermore, the vertical plate is fixedly connected between the two side edges of both the back plate and the bottom plate.
[0014] Furthermore, the vertical plates located on both sides of the back plate and the bottom plate are provided with edge sealing strips, which are used for edge sealing and bonding.
[0015] The beneficial effects of this utility model are:
[0016] 1. The present invention proposes a non-standard surface arc device, wherein the bending part of the adjustment plate adopts a multi-groove segmented design, and the bending groove and the protrusion achieve local plastic deformation through mechanical extrusion to form a continuous and smooth second arc segment, breaking through the limitations of the traditional fixed arc structure, supporting stepless adjustment, and can accurately match non-standard arc interfaces with different radii.
[0017] 2. The non-standard decorative arc device proposed in this utility model has a fixed frame that forms a closed support system through a base plate, a vertical plate and a back plate.

[0029] The present invention will now be described in detail with reference to Figures 1-8.
[0030] A non-standard decorative arc device, including
[0031] A fixed frame, comprising a base plate 10, on which a plurality of vertical plates 20 are arranged, the vertical plates 20 being parallel to each other, each vertical plate 20 having a first arc segment at its first end, and a back plate 30 connected to its second end; and
[0032] Adjustment plate 40 is installed with the fixed frame. The first side surface of the adjustment plate 40 is connected to the vertical plate 20. The first side surface is provided with a bending part corresponding to the first arc segment. By squeezing the bending part, the bending radius is adjusted so that it forms a second arc segment that matches the first arc segment.
[0033] Specifically, the fixed frame adopts a multi-layer plate assembly structure, including a horizontally arranged base plate 10 and multiple vertical plates 20 perpendicular to the base plate 10. The vertical plates 20 are arranged in parallel at equal intervals, and their bottom ends are fixedly connected to the top surface of the base plate 10. The first end (i.e., the side closest to the surface) of each vertical plate 20 forms a first arc segment inward, and the second end is perpendicularly connected to the back plate 30, forming an L-shaped support structure. The back plate 30 and the base plate 10 form a closed frame through the two vertical plates 20 on both sides, enhancing the overall rigidity.
[0034] The adjusting plate 40 has an arc-shaped decorative surface, and its inner surface is fixed to the vertical plate 20 by mechanical connectors. The adjusting plate 40 is equipped with a bending adjustment mechanism on its inner side.
[0035] The second arc segment forms a complementary curved surface with the first arc segment of the fixed frame, ensuring the geometric consistency between the decorative surface and the supporting frame, and avoiding installation gaps or stress concentrations caused by curvature deviations.
[0036] In this embodiment, the bending portion includes an arc plate 401, and the arc plate 401 is provided with a plurality of bending grooves 4011, with a protrusion formed between two adjacent bending grooves 4011; when bending the arc plate 401, the adjacent protrusions move closer to each other.
[0037] In this embodiment, the first side surface of the adjustment plate 40 is provided with a mounting groove 402, and the arc plate 401 is disposed in the mounting groove 402; the position of the adjustment plate 40 where the mounting groove 402 is provided is formed with a fitting part, and the arc plate 401 and the fitting part constitute a second arc segment.
[0038] A longitudinal mounting groove 402 is provided, in which a deformable arc plate 401 is embedded; multiple V-shaped bending grooves 4011 are equally spaced on the surface of the arc plate 401, and a trapezoidal protrusion is formed between adjacent bending grooves 4011; an elastic fitting part integrally formed with the adjustment plate 40 is provided above the groove; when it is necessary to adjust the curvature of the decorative surface, the bending groove 4011 area of the arc plate 401 is squeezed by a special clamp.
[0039] The trapezoidal protrusions undergo relative displacement under the pressure, and the distance between adjacent protrusions decreases; the arc plate 401 undergoes plastic deformation to form a continuous second arc segment; the elastic fitting part bends synchronously and fits tightly with the outer surface of the deformed arc plate 401; the final composite arc surface forms a conformal fit with the first arc segment of the fixed frame.
[0040] The bending section of the adjusting plate 40 adopts a multi-groove segmented design. The V-shaped bending groove 4011 and the trapezoidal protrusion achieve local plastic deformation through mechanical extrusion, forming a continuous and smooth second arc segment. This design breaks through the limitations of traditional fixed arc structure, supports stepless adjustment, and can accurately match non-standard arc interfaces with different radii.
[0041] In this embodiment, an adhesive layer is arranged in the mounting groove 402 of the adjusting plate 40, and the side of the arc plate 401 facing away from the bending groove 4011 is bonded to the adhesive layer.
[0042] A flexible adhesive layer is provided on the back of the arc plate 401 to ensure that it remains bonded to the bottom surface of the mounting groove 402 during deformation; the end of the adjustment plate 40 is designed to be flush with the end face of the base plate 10 to form a complete covering interface; U-shaped edge banding strips are added to the outer edges of the vertical plates 20 on both sides of the frame to achieve edge finishing and safety protection.
[0043] In this embodiment, the end of the adjusting plate 40 is flush with the end face of the base plate 10 of the fixed frame. Further, the vertical plate 20 is fixedly installed on the bottom surface of the adjusting plate 40 and / or the top wall of the base plate 10. Further, the vertical plate 20 is fixedly connected between both the side edges of the back plate 30 and the base plate 10.
[0044] In this embodiment, the vertical plates 20 located on both sides of the back plate 30 and the bottom plate 10 are provided with edge sealing strips, which are used for edge sealing and bonding.
[0045] The manufacturing process of the non-standard decorative arc device provided by this utility model is as follows:
[0046] Step S1: Select two types of board materials, namely the corresponding pattern adjustment board 40 and the bending board, both with a thickness of 18mm.
[0047] Step S2: According to the drawing requirements, fix the non-standard arc dimensions as follows: length = L, width = W, height = H, radius = R.
[0048] Step S3: Calculate the dimensions of the fixed frame based on the dimensions, seal the edges, drill holes, and fix the frame using a two-in-one connector. The length, width, and height of the frame = (L-1)*(W-18)*H. The fixed frame forms a closed support system through the base plate 10, the vertical plate 20, and the back plate 30. The L-shaped connection design between the first arc segment at the end of the vertical plate 20 and the back plate 30 significantly improves the bending and torsional resistance and prevents the decorative surface from deforming due to external forces or its own weight.
[0049] Step S4: Select an 18mm thick bending plate with a length of 3.14*1 / 4R. Mill off 1mm from the surface, reducing the thickness to 17mm. Then, cut a bending groove (4011) on the plate, leaving a 1mm thick section without cutting through. Next, use nail guns to nail the milled bending plate to the prepared frame, with the smooth surface facing up. Nails should be driven into the milled groove surface, along all four sides and in the center, ensuring flatness and a distance of WR from the edge. The plastic deformation area of the bending groove (4011) allows for resetting or secondary adjustment through reverse operation, facilitating later modification or repair and avoiding resource waste caused by complete replacement.
[0050] Step S5: Take the prepared adjustment plate 40 and cut it to the required width W and length L-R+W-R+3.14*1 / 4*R. Mill a groove in the middle, leaving a thickness of 1mm. The stroke length is 3.14R*1 / 4. First, fix one side with the two-in-one hole. Apply melamine glue to the bending plate. Then, bend the milled grooved adjustment plate 40 over so that the mounting groove 402 part just covers the bending plate. Finally, until the entire plate is in contact with the bending plate surface and the end is flush with the bottom end face of the frame. The elastic contact part of the adjustment plate 40 bends synchronously with the arc plate 401, which maintains the continuity of the decorative surface layer and disperses stress through the double-layer structure, reducing the risk of local cracking. The introduction of the flexible adhesive layer further buffers the deformation impact and ensures the bonding stability between the arc plate 401 and the mounting groove 402.
[0051] Step S6: Grind the non-standard curved bottom surface of the assembled frame using a polishing tool until smooth. After smoothing, apply melamine adhesive, then select a matching extra-wide edge banding strip and apply it to the edges. Ensure a smooth transition from one side to the other during surface bonding, avoiding any air bubbles or bulges. The standardized components of the fixed frame (base plate 10, vertical plate 20, back plate 30) and the adjustable mounting plate 40 are designed separately, supporting factory prefabrication and rapid on-site assembly, reducing the customization processing cycle. The flush interface between the end of the adjustable plate 40 and the base plate 10 simplifies the multi-unit splicing process.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
