For example: Patent CN219604865U discloses a curved template support structure. The utility model is provided with a disassembly and assembly mechanism. By inserting the mounting block into the fixed box and inserting the card block into the card slot to limit the mounting block, the support structure and the curved template can be quickly installed. At the same time, when disassembling, it is only necessary to pull the pull rod to drive the card block to completely disengage from the card slot and pull out the curved template. At the same time, the support mechanism provided in the utility model supports the curved template through the support rod, which can effectively prevent the curved template from deforming during use. At the same time, the strength of the curved support plate is strengthened by the vertical plate and the inclined surface to improve the support effect.

[0004] However, in the arc-shaped template support structure disclosed in patent CN219604865U, the reinforcement block is fixed, the radius of the arc cannot be adjusted, and the template cannot be completely positioned according to the arc during the reinforcement process. Utility Model Content

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided / sleeved with", "socketed", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Please refer to Figure 1-2 , the present utility model provides a technical solution: an adjustable support structure for an arc-shaped template, including a rectangular template 1 and a back rib 2. Two of the parallel sides of the rectangular template 1 are template bending edges 11, and the other two parallel sides are template end edges 12. A plurality of back ribs 2 are parallel to the template end edges 12 and are distributed at intervals along the template bending edges 11 and are attached to the back of the rectangular template 1. A connecting plate 3 is connected to the back rib 2. A connecting hole 31 penetrating the connecting plate 3 is opened on the connecting plate 3. A lead screw 4 is penetrated through the connecting holes 31 of the connecting plates 3 on two adjacent back ribs 2. The diameter of the connecting hole 31 is larger than the diameter of the lead screw 4. Nuts 5 are threadedly connected to both ends of the lead screw 4, and the two nuts 5 respectively abut against the opposite sides of the two connecting plates 3 connected by the lead screw 4.

[0025] When in use, the nuts 5 at both ends of the screw rods 4 connected to all the back ribs 2 are gradually rotated to make the nuts 5 squeeze the connecting plate 3 and the back ribs 2 closer to each other, so that the rectangular template 1 is bent and deformed until the rectangular template 1 is bent to fit the design curve. Since the rectangular template 1 pushes the adjacent back ribs 2 outward during adjustment, and the screw rods 4 pull the adjacent back ribs 2 together, the back ribs 2 and the connecting plate 3 will be tilted, so the diameter of the connecting hole 31 is set to be larger than the diameter of the screw rod 4, so that there is a space reserved in the connecting hole 31 for tilted connection with the screw rod 4.

[0026] The utility model adjusts the nuts 5 at both ends of the screw rod 4 connected to the back rib 2 so that the nuts 5 squeeze the connecting plate 3 and the back rib 2 closer to each other, thereby making the rectangular template 1 bend and deform to achieve a curve effect. The utility model can meet the needs of various curved forms of circular, elliptical, arc-shaped and other special-shaped structural templates with different radii. The utility model has high applicability, can be used repeatedly, and saves costs.

[0027] Furthermore, the back rib 2 includes a metal square tube 21 and a wooden square 22. The metal square tube 21 is wrapped around the wooden square 22 to form a wooden square with a metal shell. The metal square tube 21 is provided with an installation opening 23 that penetrates the metal square tube 21 transversely. The back rib 2 is connected to the back of the rectangular template 1 by nailing steel nails through the wooden square 22 at the installation opening 23 and nailing them into the rectangular template 1. This increases the strength of the back rib 2 and facilitates the connection between the back rib 2 and the rectangular template 1.

[0028] Furthermore, a clamp 6 is connected to the connecting plate 3, and the clamp 6 is opened on one side and the shape of the opening is consistent with the cross-sectional shape of the back rib 2. The clamp 6 is fixed to the back rib 2 by snapping the opening, so as to facilitate the adjustment of the height position of the connecting plate 3 on the back rib 2, and prevent any back rib 2 from conflicting with the position of the connecting plates 3 connected to the adjacent back ribs 2 on both sides, and the number of connecting plates 3 can be adjusted as needed to ensure that the adjacent back ribs 2 are firmly connected.

[0029] Furthermore, the rectangular template 1 is a metal plate or a plastic plate with elasticity, so that the rectangular template 1 can be bent in a curve.

[0030] Furthermore, a plurality of back ribs 2 are evenly spaced and attached to the back of the rectangular template 1, so that the length of the rectangular template 1 between any two back ribs 2 is equal, thereby making the bending arc consistent and making the overall bending arc of the rectangular template 1 smoother.

[0031] Specifically, two connecting plates 3 are provided on each of the two backing ribs 2 at both ends of the rectangular template 1, and the two connecting plates 3 are respectively connected to the upper and lower halves of the backing rib 2. Four connecting plates 3 are provided on the backing ribs 2 between the two backing ribs 2 at both ends of the rectangular template 1. Two of the connecting plates 3 are aligned with the two connecting plates 3 on the backing rib 2 adjacent to the left side of the backing rib 2 to which they are connected, and the other two connecting plates 3 are aligned with the two connecting plates 3 on the backing rib 2 adjacent to the right side of the backing rib 2 to which they are connected. Thus, two sets of adjusting assemblies composed of connecting plates 3, lead screws 4, and nuts 5 are connected between each two backing ribs 2, and the structure is more stable.

[0032] Further, a sleeve 7 is sleeved on the lead screw 4 at the position between the two connecting plates 3 to protect the lead screw 4 and prevent the nut 5 from being unable to rotate normally due to damage caused by collision of the lead screw 4.

[0033] Specifically, the sleeve 7 is made of a PVC sleeve.

[0034] Specifically, the square metal pipe 21 is made of an aluminum square pipe, which has high strength and light weight.

[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation.
