[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figs. 1-3 The utility model provides a technical scheme:

[0025] A precise hardware with high bending resistance, comprising:

[0026] Main body structure;

[0027] The main body structure includes web 1, and both ends of web 1 are provided with positioning hole 6 for fixing hardware;

[0028] The main body structure is the basic bearing part of the whole hardware, and web 1 is the key component of the main body structure. The positioning hole 6 provides a fixing point, when the hardware connecting piece is used to connect two main body parts, the hardware and other main components can be firmly connected together through bolts, pins and the like passing through the positioning hole 6, ensuring that the hardware does not displace during the working process, thereby stably transmitting force.

[0029] The positioning hole 6 enables the hardware to be accurately and stably installed on the main body part that needs to be connected, ensuring the reliability and accuracy of the connection and laying a foundation for the subsequent hardware to perform the connection and load-bearing functions.

[0030] It also includes a bending-resistant structure for improving the bending resistance of the web plate 1; the bending-resistant structure includes two sets of arched plates 3 and two sets of reinforcing ribs 2, the two sets of arched plates 3 are respectively arranged on the upper and lower surfaces of the web plate 1, and the two sets of reinforcing ribs 2 are respectively located on the two sides of the web plate 1, and the reinforcing ribs 2 are integrally formed with the web plate 1.

[0031] The arched plates 3 are designed in an arch shape, and when the hardware is subjected to a bending force, the arched structure can convert the bending force into axial pressure and horizontal thrust, so that the internal structure mainly bears compressive stress. Since the material generally has high strength in compression, the ability of the region to resist bending deformation can be effectively improved. The reinforcing ribs 2 integrally formed on the two sides of the web plate 1 increase the local stiffness and overall bending resistance of the hardware. When subjected to a bending force, the reinforcing ribs 2 can share a portion of the load and transmit the force to a wider area, reducing the deformation of the main structure (web plate 1).

[0032] Through the synergistic effect of the arched plates 3 and the reinforcing ribs 2, the bending resistance of the web plate 1 is significantly improved, solving the problem of low material utilization and inability to fully utilize the mechanical properties of traditional single flat or columnar structures. The hardware can better maintain its shape and performance when subjected to a bending force, prolonging its service life.

[0033] Further, please refer to Figs. 1-3 :

[0034] One end of the web plate 1 is integrally formed with a tenon 4, and the other end of the web plate 1 is integrally formed with a mortise 5, the tenon 4 and the mortise 5 are matched, and the positioning hole 6 is opened on the two side walls of the tenon 4 and the mortise 5.

[0035] The tenon 4 and the mortise 5 are a traditional and effective connection method. When multiple hardware need to be connected or the hardware needs to be connected with other main body parts, the tenon 4 of one hardware is inserted into the mortise 5 of another, and the two are tightly matched, which can effectively transmit force and make each part work together. The positioning hole 6 is opened on the two side walls of the tenon 4 and the mortise 5, further enhancing the stability of the connection. By tightening through the positioning hole 6 with bolts and the like, relative sliding between the tenon 4 and the mortise 5 during the force process is prevented.

[0036] The design of the tenon 4 and the mortise 5 avoids the stress concentration problem that may be caused by traditional connection methods, improves the strength and stability of the connection part, and ensures that the hardware can reliably transmit and withstand various forces when connecting two main body parts, thereby enhancing the bending resistance of the overall structure.

[0037] Wherein, please refer to Figs. 1-3 :

[0038] The reinforcing rib 2 is circularly arranged, and the diameter of the reinforcing rib 2 is 1.5-2 times of the thickness of the web plate 1.

[0039] The circular reinforcing rib 2 has uniform stress distribution characteristics and can more effectively disperse the force to the surrounding area when bearing the bending force. The diameter of the reinforcing rib 2 is set to be 1.5-2 times of the thickness of the web plate 1 based on the consideration of mechanical property optimization. The reinforcing rib 2 with appropriate size can provide sufficient rigidity and strength without significantly increasing the material usage and overall weight, so that the reinforcing rib 2 can play the best effect when sharing the bending load.

[0040] The reinforcing rib 2 with such specification design can not only ensure the effective improvement of the bending resistance of the web plate 1, but also avoid the waste of materials and the increase of the weight of the hardware due to the overlarge reinforcing rib 2, so as to achieve the balance between the performance improvement and the cost and weight control.

[0041] In addition, please refer to Figs. 1-2 :

[0042] The arch-shaped plate 3 is arc-shaped designed, and the connecting plates 8 are integrally arranged at both ends of the arch-shaped plate 3, and the connecting holes 9 are arranged on the connecting plates 8. The two groups of convex columns 7 are symmetrically arranged on the upper and lower surfaces of the web plate 1, the connecting holes 9 on the connecting plates 8 are passed through by the convex columns 7, and the convex columns 7 are locked and fixed by the nuts.

[0043] The arch-shaped plate 3 is connected with the web plate 1 through the connecting plates 8 at both ends, the convex columns 7 are provided with external threads, the threaded convex columns 7 pass through the connecting holes 9 on the connecting plates 8, and then the nuts are locked, so as to form a detachable connection mode. The connection mode makes the arch-shaped plate 3 firmly fixed on the web plate 1, and when the hardware is subjected to the bending force, the arch-shaped plate 3 can tightly cooperate with the web plate 1 to resist the bending deformation. At the same time, the detachable design is convenient for operation when the arch-shaped plate 3 is damaged or needs to be replaced.

[0044] The connection stability between the arch-shaped plate 3 and the web plate 1 is ensured, so that the arch-shaped plate 3 can fully play its role in improving the bending resistance of the web plate 1. Moreover, the detachable connection mode increases the maintainability and flexibility of the hardware, and reduces the later maintenance cost.

[0045] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as the limitation of the utility model, and the ordinary skilled in the art can change, modify, replace and transform the above-mentioned embodiments within the scope of the utility model.
