[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] According to an embodiment of this utility model, a U-shaped steel canopy processing mold is provided. Please refer to [link / reference]. Figures 1 to 3The system includes: an elastic steel strip 1 extending along a preset arc trajectory; a support rod 2, which is arranged vertically at intervals from the elastic steel strip 1; and an adjustment component 3 connected to both the elastic steel strip 1 and the support rod 2, which is used to adjust the curvature of the elastic steel strip 1. The adjustment component 3 drives the elastic steel strip 1 to move relative to the support rod 2, thereby adjusting the position of the elastic steel strip 1 relative to the support rod 2 and thus adjusting the curvature of the elastic steel strip 1.

[0025] By adopting the above technical solution, and through the coordinated structure of the elastic steel belt 1, support rod 2, and adjustment component 3, the adjustment component 3 can drive the elastic steel belt 1 to move relative to the support rod 2, thereby achieving multi-level adjustment of the curvature of the elastic steel belt 1. This structure simplifies the curvature adjustment process through mechanical linkage, improves the processing applicability of U-shaped steel sheds of different specifications, and ensures the controllability of the distance between the elastic steel belt 1 and the support rod 2, thus enhancing the overall structural stability.

[0026] Please refer to Figure 1 The adjusting assembly 3 includes at least three sets of adjusting members 4, each set of adjusting members 4 being arranged at intervals along the extension direction of the elastic steel strip 1. Each set of adjusting members 4 has a first connecting part and a second connecting part. The first connecting part of each set of adjusting members 4 is connected to the elastic steel strip 1, and the second connecting part of each set of adjusting members 4 is connected to the support rod 2. The first connecting part and the corresponding second connecting part of each set of adjusting members 4 are adjustablely connected so that the curvature of the elastic steel strip 1 can be adjusted by adjusting the relative position between the first connecting part and the second connecting part of at least one adjusting member 4 in each set of adjusting members 4.

[0027] By adopting the above technical solution, the adjustment component 3 uses at least three sets of adjustment parts 4 distributed at intervals along the extension direction of the elastic steel strip 1, and the first connecting part and the second connecting part of each set of adjustment parts 4 are connected in an adjustable manner, which can realize independent adjustment of the local curvature of the elastic steel strip 1; this multi-point adjustment design makes the deformation process of the elastic steel strip 1 uniformly stressed, avoids plastic deformation caused by single-point stress concentration, and significantly improves the curvature adjustment accuracy and molding quality.

[0028] Please refer to Figure 1The adjusting component 4 includes: a first screw 5, which is rotatably disposed on the side of the elastic steel strip 1 facing the support rod 2; the first screw 5 extends along a first preset direction; the first screw 5 forms a first connecting portion; a second screw 6, which extends along the first preset direction; the second screw 6 is rotatably disposed on the side of the support rod 2 facing the elastic steel strip 1; the second screw 6 forms a second connecting portion; and a rotating portion, which is located between the first screw 5 and the second screw 6, wherein one end of the first screw 5 away from the elastic steel strip 1 and one end of the elastic steel strip 1 of the second screw 6 are both connected to the rotating portion, and the first screw 5 and the second screw 6 are movably disposed relative to the rotating portion along the direction from the elastic steel strip 1 to the support rod 2; so as to adjust the curvature of the elastic steel strip 1 by adjusting the position of the first screw 5 relative to the rotating portion and / or adjusting the position of the second screw 6 relative to the rotating portion.

[0029] By adopting the above technical solution, the adjusting component 4 achieves bidirectional movement adjustment of the first screw 5 and the second screw 6 relative to the rotating part through the combination structure of the first screw 5, the second screw 6 and the rotating part; this design uses the principle of screw transmission to convert rotational motion into linear displacement, which can finely adjust and control the curvature of the elastic steel belt 1, making the operation simple and the adjustment amount visible, while the compact transmission structure saves space.

[0030] Please refer to Figure 1 The adjusting component 4 further includes: a first sleeve 7, which is threadedly connected to the first screw 5; a second sleeve 8, which is threadedly connected to the second screw 6; and a connecting rod 9, which extends along the extension direction of the first screw 5 and is connected to the first sleeve 7 and the second sleeve 8; wherein the first sleeve 7, the second sleeve 8, and the connecting rod 9 constitute a rotating part.

[0031] By adopting the above technical solution, the rotating part consisting of the first sleeve 7, the second sleeve 8, and the connecting rod 9 achieves synchronous rotation adjustment of the first screw 5 and the second screw 6 through a threaded connection. This structure ensures the consistency of the movement trajectory of each component during adjustment, avoids the twisting of the elastic steel belt 1 due to asymmetrical displacement, improves adjustment stability, and enhances the fatigue resistance of the transmission components.

The second protrusion 12 is positioned away from the support rod 2 and towards the elastic steel strip 1; at least three first connectors 13, each first connector 13 having a first rotating cavity 15, each first protrusion 11 corresponding to each first connector 13 and each adjusting member 4, the end of each first protrusion 11 away from the elastic steel strip 1 located within the corresponding first rotating cavity 15, and each first connector 13 rotatably connected to the corresponding first protrusion 11; the side of each first connector 13 away from the first protrusion 11 is connected to the corresponding adjusting member 4; at least three second connectors 14, each second protrusion 1... Each of the 2 components is respectively provided with a second connecting member 14 and an adjusting member 4. Each second connecting member 14 is provided with a second rotating cavity 16. The end of each second protrusion 12 away from the support rod 2 is located in the corresponding second rotating cavity 16, and each second connecting member 14 is rotatably connected to the corresponding second protrusion 12. The side of each second connecting member 14 away from the second protrusion 12 is connected to the corresponding adjusting member 4. At least three first limiting members are provided, each first limiting member is respectively provided with a first connecting member 13, and each first limiting member is movable relative to the corresponding first connecting member 13. The configuration includes at least a portion of each first limiting member sequentially passing through a corresponding first connector 13 and a first protrusion 11, with at least a portion of the first limiting member protruding from the first connector 13 to limit the first protrusion 11; at least three second limiting members are configured one-to-one with each second connector 14, each second limiting member is movably configured relative to the corresponding second connector 14, and at least a portion of each second limiting member sequentially passing through a corresponding second connector 14 and a second protrusion 12, with at least a portion of the second limiting member protruding from the second connector 14 to limit the second protrusion 12.

[0033] By adopting the above technical solution, the connecting component 10, through the rotational engagement structure of the first protrusion 11, the second protrusion 12, the first connector 13, and the second connector 14, enables the elastic steel belt 1 and the support rod 2 to adaptively rotate in multiple directions during the curvature adjustment, avoiding the jamming phenomenon caused by rigid connection; the first limiting member and the second limiting member adopt a linkage structure, which can quickly limit the displacement of the first protrusion 11 or the second protrusion 12 when locked in position, ensuring the positioning reliability of the adjusted structure.

[0034] Furthermore, one of the first protrusions 11 extends perpendicularly to the extension direction of the support rod 2, while the other first protrusions 11 extend along the extension direction of the elastic steel strip 1.

[0035] Please refer to Figure 2 The first limiting member includes: a first sliding rod 19, which extends along the width direction of the first connector 13 and passes through the first connector 13 along the width direction of the first connector 13; a first horizontal plate 20, whose extension direction is perpendicular to the extension direction of the first sliding rod 19; the first horizontal plate 20 is located at the top of the first connector 13, one end of the first sliding rod 19 is connected to the bottom of the first horizontal plate 20, and the other end of the first sliding rod 19 is movably inserted into the first horizontal plate 20 through the first connector 13; a first vertical rod 21, which extends along the width direction of the first connector 13, one end of the first vertical rod 21 is connected to the bottom of the first horizontal plate 20, and the other end of the first vertical rod 21 passes through the first connector 13 and the first protrusion 11 in sequence along the width direction of the first connector 13; the first vertical rod 21 and the first sliding rod 19 are spaced apart.

[0036] By adopting the above technical solution, the first limiting member, through the vertical linkage design of the first sliding rod 19, the first horizontal plate 20 and the first vertical rod 21, can realize the simultaneous control of horizontal sliding and vertical insertion actions by one hand operation; this structure simplifies the limiting operation steps, and the limiting method of the first vertical rod 21 passing through the first protrusion 11 can effectively resist shear force and prevent the elastic steel strip 1 from being accidentally displaced during processing.

[0037] Please refer to Figure 3 The second limiting member includes: a second sliding rod 22, which extends along the width direction of the second connector 14 and passes through the second connector 14 along the width direction of the second connector 14; a second horizontal plate 23, whose extension direction is perpendicular to the extension direction of the second sliding rod 22; the second horizontal plate 23 is located at the top of the second connector 14, one end of the second sliding rod 22 is connected to the bottom of the second horizontal plate 23, and the other end of the second sliding rod 22 passes through the second connector 14 and is movably inserted into the second horizontal plate 23; a second vertical rod 24, which extends along the width direction of the second connector 14, one end of the second vertical rod 24 is connected to the bottom of the second horizontal plate 23, and the other end of the second vertical rod 24 passes through the second connector 14 and the second protrusion 12 in sequence along the width direction of the second connector 14; the second vertical rod 24 and the second sliding rod 22 are spaced apart.

[0038] By adopting the above technical solution, the second limiting component adopts a structure of a second sliding rod 22, a second horizontal plate 23 and a second vertical rod 24 that are mirror-symmetrical to the first limiting component, ensuring that the limiting action on the support rod 2 side is synchronized and symmetrical with the elastic steel strip 1 side; this design improves the force balance of the overall connecting component 10 and avoids the mold skewing problem caused by the failure of the single-sided limiting component.

[0039] Please refer to Figure 2 The first limiting member further includes: a first fixing ring, which is located in the first rotating cavity 15 and fixed on the first sliding rod 19; and a first spring 26, which is located in the first rotating cavity 15 and sleeved on the first sliding rod 19. The two ends of the first spring 26 are respectively connected to the inner sidewall of the first fixing ring and the first connecting member 13.

[0040] By adopting the above technical solution, the cooperation between the first spring 26 and the first fixed ring enables the first sliding rod 19 to automatically return to its initial position when the limit is released, reducing the manual reset operation time; the spring buffering effect can absorb the vibration and impact during the adjustment process, reduce the wear between the first sliding rod 19 and the first connecting member 13, and extend the service life of the limit mechanism.

[0041] Please refer to Figure 3 The second limiting member also includes: a second fixing ring, which is located inside the second rotating cavity 16 and fixed to the second sliding rod 22; and a second spring 28, which is located inside the rotating cavity and sleeved on the second sliding rod 22. The two ends of the second spring 28 are respectively connected to the inner sidewall of the second fixing ring and the second connecting member 14.

[0042] By adopting the above technical solution, the symmetrical arrangement of the second spring 28 and the second fixed ring enables the second limiting member to have the same automatic reset and buffering functions as the first limiting member; the synergistic effect of the dual spring system further optimizes the dynamic response performance of the connecting component 10, ensuring that the limiting effect remains stable even under high-frequency adjustment operations.

[0043] Working principle:

[0044] First, release the locking of the first and second limiting members, and pull the first horizontal plate 20 and the second horizontal plate 23 outward to disengage the first vertical rod 21 and the second vertical rod 24 from the first protrusion 11 and the second protrusion 12. Then, install each adjusting component 4. After installation, loosen the first horizontal plate 20 and the second horizontal plate 23. Under the action of the first spring 26 and the second spring 28, the first vertical rod 21 and the second vertical rod 24 automatically return to their locked positions. Then, rotate the first sleeve 7 or the second sleeve 8 according to the required arc. The movement of the first screw 5 and the second screw 6 causes the elastic steel strip 1 to deform. During the adjustment process, the first protrusion 11 and the second protrusion 12 can adaptively rotate within the first rotating cavity 15 and the second rotating cavity 16. After processing, the mold can be disassembled by reversing the operation, which facilitates the disassembly and storage of the mold and does not occupy space.
