Description

Technical Field

[0001] This invention relates to the field of cutting tools, and in particular to a reinforced cutting tool. Background Technology

[0002] Hand-operated cutting tools such as sickles, machetes, and kitchen knives are widely used in agricultural harvesting, forestry logging, and household applications. However, their traditional design and manufacturing processes have significant technical flaws. In existing technologies, blade strength often relies on increased thickness, leading to difficulty in cutting during actual use and creating a vicious cycle of "thicker blades - harder to cut." Even with optimizations through processes like quenching and grinding, the fundamental contradiction between strength and thickness remains unresolved. Furthermore, the handle and blade of these knives are often formed in a single process, resulting in a uniform thickness and an excessively high handle weight, which can cause hand fatigue. While thinning the handle through secondary processing could reduce the weight percentage, it would increase manufacturing costs. Therefore, this paper proposes a reinforced knife. Summary of the Invention

[0003] The purpose of this invention is to provide a reinforced cutting tool to solve the technical problems mentioned in the background art.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A reinforced cutting tool includes a handle and a blade. The handle includes a handle and a connecting plate that are connected to each other. The connecting plate is arranged parallel to the blade and is connected to the side of the blade.

[0005] In a preferred embodiment, the handle is configured as a cylindrical, plate-shaped, or block-shaped component.

[0006] In a preferred embodiment, the system further includes a protective member, which is provided in multiple forms. The protective member includes a U-shaped clamping plate with a groove on its inner side, and a magnet is provided in the groove.

[0007] In a preferred embodiment, the handle and the connecting plate are integrally formed.

[0008] In a preferred embodiment, the connecting plate extends from one end of the blade to the other end.

[0009] In a preferred embodiment, the blade includes an upper part and a lower part, which are connected in a staggered manner. A connecting plate is attached to the upper part, and a cutting edge is provided at the bottom of the lower part. The cutting edge is located within the middle dividing surface of the connecting plate and the upper part.

[0010] In a preferred embodiment, the thickness of the blade is set to 3mm, and the thickness of the connecting plate and the sidewall thickness of the handle are set to 2mm.

[0011] In a preferred embodiment, the blade is made of alloy steel.

[0012] In a preferred embodiment, a reinforcing rib is further included, which is disposed along the top edge of the connecting plate and the blade, connecting the blade and the connecting plate.

[0013] In a preferred embodiment, the reinforcing rib, the blade, and the connecting plate are welded together.

[0014] In a preferred embodiment, the reinforcing rib is formed by folding the top of the blade.

[0015] Compared with the prior art, the present invention provides a reinforced cutting tool with the following beneficial effects: In terms of weight distribution, the handle, as the grip part, is designed to be relatively light, while the blade maintains the necessary weight. This makes the overall center of gravity of the knife closer to one side of the blade. This weight distribution method conforms to ergonomic and mechanical principles, allowing the blade's own weight to generate greater inertial impact force during chopping, effectively improving cutting efficiency and solving the problem of traditional knives where the center of gravity shifts due to an excessively heavy handle, making it difficult to generate force. At the same time, the design of the connecting plate connecting to the side of the blade, without increasing the thickness of the blade itself, forms a composite structure through the superposition of the two. This is equivalent to adding an extra support layer to the side of the blade, significantly increasing the overall structural thickness of the knife and greatly enhancing its structural strength and impact resistance. Furthermore, this increase in thickness only applies to the side connection area of ​​the blade and does not involve the part of the blade near the cutting edge. This ensures that the cutting edge remains at an appropriate thickness, guaranteeing both the sharpness of the blade and avoiding the problem of increased cutting resistance due to an excessively thick cutting edge. Thus, while enhancing structural strength, it also takes into account the ease of cutting, balancing the contradiction between strength and cutting performance. This effectively solves the technical problem of traditional knives where thickening the cutting edge to ensure strength leads to difficulty in cutting, and can reduce the amount of alloy steel used while ensuring the effect.

[0061] The present invention will be further described in detail below with reference to the accompanying drawings.

[0062] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0063] like Figures 1 to 9As shown, a reinforced knife includes a handle and a blade 1. The handle includes a handle 6 and a connecting plate 7 connected to each other. The connecting plate 7 and the blade 1 are arranged parallel to each other, and the connecting plate 7 is connected to the side of the blade 1.

[0064] This invention provides a reinforced knife. From a weight distribution perspective, the handle 6, as the gripping part, is designed to be relatively light, while the blade 1 maintains the necessary weight. This makes the overall center of gravity of the knife closer to one side of the blade 1. This weight distribution method conforms to ergonomic and mechanical principles, allowing for greater inertial impact force during chopping using the weight of the blade 1, effectively improving chopping efficiency and solving the problem of traditional knives where the center of gravity shifts due to the excessive weight of the handle 6, making it difficult to generate force. Simultaneously, the design of the connecting plate 7 connecting to the side of the blade 1, without increasing the thickness of the blade 1 itself, forms a composite structure through their superposition. This is equivalent to adding an extra support layer to the side of the blade 1, significantly increasing the overall structural thickness of the knife and greatly enhancing its structural strength and impact resistance. In addition, this increase in thickness only applies to the side connection area of ​​the blade 1 and does not involve the part of the blade 1 near the cutting edge 4. This ensures that the cutting edge 4 maintains an appropriate thinness, which not only guarantees the sharpness of the blade but also avoids the problem of increased cutting resistance due to excessive thickness of the cutting edge 4. Thus, while enhancing the structural strength, it also takes into account the ease of cutting, balancing the contradiction between strength and cutting performance. This effectively solves the technical problem of traditional knives making it difficult to cut by thickening the cutting edge 4 to ensure strength.

[0065] For ease of gripping, the handle 6 is cylindrical. The handle 6 can also be other shapes, as long as they achieve the purpose of easy gripping, such as plate-shaped or block-shaped.

[0066] like Figures 42 to 44 As shown, a reinforced knife in this embodiment also includes protective components. Multiple protective components are provided, each including a U-shaped clamping plate 9. The inner side of the U-shaped clamping plate 9 has a groove 10, and a magnet 11 is disposed in the groove 10. The protective component design combines protection, convenient storage, and center-of-gravity adjustment. The U-shaped clamping plate of the protective component can precisely clamp the blade edge. Utilizing the enveloping nature of the U-shaped structure, it effectively isolates the blade edge from external contact, preventing damage or dulling of the blade edge when the knife is idle or being carried. It also prevents accidental contact with the sharp blade edge, thus providing dual safety protection for both the blade edge and the user.

[0067] Meanwhile, when the knife is in use, the protective component can be quickly clipped onto the top of the knife, eliminating the need for an additional storage box or separate storage. This solves the problems of traditional protective accessories being easily lost and cumbersome to store, ensuring that the protective component and the knife always remain integrated, making the switching between use and storage more efficient.

[0068] Furthermore, by adjusting the positions of multiple protective components at the top of the blade, the overall center of gravity distribution of the blade can be flexibly changed according to actual usage scenarios (such as needing stronger inertia when chopping harder materials, or needing a more stable feel for fine cutting). Combined with the strong adsorption effect of Magnet 11, this ensures that the protective components firmly adhere to the blade after adjustment, preventing displacement due to vibration or force during use. This guarantees the accuracy of the center of gravity adjustment and avoids loose components affecting use, significantly improving the blade's adaptability and user experience under different working conditions.

[0069] The handle 6 can also have other configuration forms, such as... Figure 6 As shown, the handle is set as a plate. During actual assembly, wooden parts are installed on both sides of the plate to form a complete hand handle.

[0070] Furthermore, the handle 6 and the connecting plate 7 are integrally formed. During the manufacturing process, the handle 6 and the connecting plate 7 are manufactured as a single piece, which is quick and convenient, and they have the same thickness. The handle 6 does not require additional processing.

[0071] In this embodiment, the connecting plate 7 extends from one end of the blade 1 to the other end, thereby achieving a more comprehensive structural reinforcement effect on the blade 1.

[0072] Furthermore, the blade 1 includes an upper part 2 and a lower part 3, which are staggered and connected. The connecting plate 7 is fitted to the upper part 2, and a cutting edge 4 is provided at the bottom of the lower part 3. The cutting edge 4 is located within the middle dividing surface 5 of the connecting plate 7 and the upper part 2. The staggered connection of the upper part 2 and the lower part 3 of the blade 1 provides space for the installation of the connecting plate 7, allowing the connecting plate 7 to fit tightly against the upper part of the blade 1, resulting in a more compact and reasonable overall layout. This staggered design ensures the overall rigidity of the blade 1 while creating favorable conditions for a stable connection between the connecting plate 7 and the blade 1. During use, the lower edge of the connecting plate 7 abuts against the upper edge of the lower part 3, which is beneficial for applying force. Meanwhile, the bottom of the lower part 3 is provided with a blade 4, and the blade 4 is located within the middle dividing surface 5 of the connecting plate 7 and the upper part 2. When the user applies a chopping force, the force can be transmitted through the force transmission path formed by the upper part of the blade 1, the connecting plate 7 and the handle 6, and act on the central area of ​​the blade 4. This effectively reduces the dispersion and deviation of the force, so that each force can be converted into the kinetic energy of the chopping more efficiently, significantly improving the force application effect and cutting efficiency. Especially when facing harder materials, this center-corresponding force design makes it easier for the blade to cut in, avoiding blade deflection or jamming caused by force deviation.

[0073] The intermediate dividing surface 5 refers to the plane that is parallel to the blade 1 and bisects the connecting plate 7 and the blade 1.

[0074] In this embodiment, the thickness of the blade 1 is set to 3mm, and the thickness of the connecting plate 7 and the side wall thickness of the handle 6 are set to 2mm.

[0075] To effectively ensure structural strength, the blade 1 is made of alloy steel, while the handle can be made of ordinary steel.

[0076] To further enhance structural strength, this embodiment of the reinforced blade also includes a reinforcing rib 8. The reinforcing rib 8 is positioned along the top edge of the connecting plate 7 and the blade body 1, connecting the blade body 1 and the connecting plate 7. Extending along the top edges of both, the reinforcing rib 8 acts like a robust "skeleton" at the connection, effectively dispersing the longitudinal and lateral stresses generated during cutting. When the blade is under stress, the force is not only transmitted through the side connection between the connecting plate 7 and the blade body 1, but also dispersed by the support structure formed at the top by the reinforcing rib 8, preventing cracking or loosening at the connection due to localized stress concentration. Simultaneously, the reinforcing rib 8, the blade body 1, and the connecting plate 7 form a closed, load-bearing unit, making the connection between the three more compact and robust, significantly improving the overall structural rigidity of the blade. Even when repeatedly striking hard objects, it maintains a stable shape, further extending the blade's service life, and does not interfere with the normal cutting of the cutting edge 4, achieving a secondary strengthening of structural strength. Furthermore, the reinforcing rib 8 also increases the weight of the blade body 1, making it more advantageous for cutting.

[0077] In one embodiment of this invention, the reinforcing rib 8, the blade 1, and the connecting plate 7 are welded together to achieve a good connection effect.

[0078] like Figures 38-39 As shown, a slot is provided on the reinforcing rib 8, and the top edges of the blade 1 and the connecting plate 7 are clamped in the slot.

[0079] like Figures 40-41 As shown, for ease of processing, the handle 6 can be configured as a split type, consisting of two parts, upper and lower.

[0080] In another embodiment of this example, such as Figures 10 to 19As shown, the reinforcing rib 8 is formed by folding the top of the blade 1 and is welded to the connecting plate 7. This design achieves the following technical effects: First, the folding makes the reinforcing rib 8 integrally formed with the blade 1, eliminating the need for separate reinforcing rib manufacturing, reducing the number of parts and assembly steps, simplifying the production process, and lowering processing costs. Second, the integrated structure avoids welding between the reinforcing rib 8 and the blade 1, eliminating potential stress concentration and incomplete welding issues that may arise from welding, thus improving the stability and structural reliability of the connection between the reinforcing rib 8 and the blade 1. Third, only the folded reinforcing rib 8 needs to be welded to the connecting plate 7, reducing one welding step, shortening assembly time, while ensuring the reinforcing rib 8's supporting and reinforcing effect on the blade 1 and the connecting plate 7. This effectively disperses the impact stress, further strengthening the overall structural strength of the tool, balancing production efficiency and performance.

[0081] like Figures 20 to 37 As shown, as an alternative, the reinforcing rib 8 can also be formed by folding the top of the connecting plate 7. The connecting plate 7 is made of ordinary steel, which has lower cost and lower strength, and can be bent.

[0082] The above description of the embodiments is provided to facilitate understanding and use of the present invention by those skilled in the art. It is obvious to those skilled in the art that various modifications can be easily made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments.
