Description

Technical Field

[0001] This invention belongs to the field of fishhook testing technology, specifically referring to a novel composite material fishhook strength testing device. Background Technology

[0002] To prevent fishhooks from rusting and breaking due to seawater corrosion during fishing, fishhooks made of ceramic matrix composites have emerged. In fishhooks made of this material, the barb is crucial for securing the catch and for supporting the hook itself. The barb affects the fishing experience. The barb is a reverse-pointed barb designed inside the hook point. Its main functions include preventing the fish from getting off the hook (the barb can embed into the fish's mouth tissue to reduce the risk of the fish escaping), securing live bait, and adapting to special scenarios.

[0003] The core objective of barb bending strength testing is to ensure that the barb structure does not undergo permanent deformation or breakage in actual fishing. However, existing testing technologies have significant limitations: traditional methods mainly rely on unidirectional tensile testing, which only simulates the stress scenario by applying force vertically or axially. This single-dimensional test cannot reproduce the multi-directional complex forces generated by the struggle of fish in actual fishing, so the final test data deviates from the actual performance. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to detect the tensile strength of the barb position of the fishhook and to provide a novel composite material fishhook strength testing device, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by the present invention is as follows: A novel composite material fishhook strength testing device includes a tensile component, wherein the tensile component is configured to tensile the barb position of the fishhook.

[0008] Furthermore, a sliding block is located at the front end of the electric cylinder.

[0009] Furthermore, a servo motor is located on the outside of the sliding block, and there are rotating shafts on both sides of the sliding block. The servo motor is configured to drive the rotating shafts to rotate, thereby changing the stretching angle.

[0010] Furthermore, the connecting bracket is located outside the rotating shaft.

[0011] Furthermore, a pull line is installed inside the connecting frame and is used during operation to place at the barb position of the fishhook in order to complete the tensile test of the fishhook barb.

[0012] Furthermore, the novel composite material fishhook strength testing device proposed in this invention includes a bottom fixing component, which is disposed below the side fixing component. The bottom fixing component is configured to fix the bottom position of the fishhook to prevent the fishhook from shaking during the testing process.

[0015] Furthermore, the tension assembly also includes a tension sensor and a connecting shaft.

[0016] Furthermore, the tension sensor is disposed on the upper surface of the connecting frame. The tension sensor is used to record the tension exerted by the line on the barb of the hook. The front of the tension sensor is provided with a connecting shaft, which is configured to allow for the removal and replacement of the detection line.

[0017] Furthermore, the side fixing assembly includes a first fixing platform, a movable port, a hydraulic device, a hydraulic rod, and a limiting plate.

[0018] Furthermore, a movable opening is provided in the middle of the first fixed platform. Hydraulic devices are symmetrically arranged on the surface of the first fixed platform with the movable opening as the axis. Each hydraulic device has a hydraulic rod at its front end, and each hydraulic rod is located inside the movable opening. The port of each hydraulic rod is provided with a limiting plate, and the limiting plates move relative to each other. The fishhook to be tested is placed inside the limiting plate, and the limiting plate is used to fix the fishhook to be tested.

[0019] Furthermore, the side fixing assembly also includes a cylinder, a push rod, a cross bracket, and a pressure plate.

[0020] Furthermore, the cylinder is located on the upper part of the hydraulic device, and the cylinders are symmetrically arranged on the surface of the first fixed platform with the moving port as the axis. Each cylinder has a push rod at its lower part, a horizontal support at the bottom of the push rod, and a pressure plate at the bottom of the horizontal support. The pressure plate is used to press against the top of the fishhook.

[0021] Furthermore, the side fixing assembly also includes a telescopic device and a pressing column.

[0022] Furthermore, the horizontal support is provided with a telescopic device in the middle, and a pressing column is provided inside the telescopic device. The pressing column faces the inside of the moving port. The telescopic device is configured to control the extension and retraction of the pressing column.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0033] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this invention proposes a novel composite material fishhook strength testing device, including a tensile component 1. The tensile component 1 includes a placement platform 11, a sliding groove 12, a sliding block 13, a rotating shaft 14, a servo motor 15, a connecting frame 16, a tension sensor 17, a connecting shaft 18, a pull line 19, an electric cylinder 110, and a base 111.

[0035] In this embodiment of the invention, a sliding groove 12 is provided in the middle of the placement platform 11, and a sliding block 13 is movably disposed inside the sliding groove 12. The sliding block 13 can move back and forth along the sliding groove 12. A base 111 is fixedly disposed on the upper surface of the placement platform 11, and the base 111 is disposed at the tail end of the sliding groove 12. An electric cylinder 110 is fixedly disposed inside the base 111, and the front end of the electric cylinder 110 is connected to the sliding block 13. The electric cylinder 110 can drive the sliding block 13 to move. Rotating shafts 14 are provided on both sides of the sliding block 13. The rotating shafts 14 pass through the interior of the sliding block 13, and are movably connected to the sliding block 13. A servo motor 15 is connected to the outside of one of the rotating shafts 14, and the servo motor 15 can drive the sliding block 13 to move. The rotating shaft 14 rotates along the inside of the sliding block 13, and a connecting frame 16 is fixedly connected to the outside of the rotating shaft 14. When the rotating shaft 14 rotates, it will drive the connecting frame 16 to rotate together. A connecting shaft 18 is fixedly connected to the front end of the connecting frame 16. The connecting shaft 18 and the connecting frame 16 are connected by bolts. A pull line 19 is provided inside the connecting shaft 18. The pull line 19 is placed at the barb position of the fishhook. The pull line 19 is used to lock the hook at the barb position. The pull line 19 can be replaced periodically by replacing the connecting shaft 18, so that the detection data is more complete. A tension sensor 17 is provided on the upper part of the connecting frame 16. The tension sensor 17 is connected to the pull line 19 through a data cable. The tension sensor 17 can detect the tension on the pull line 19.

[0036] Because fishhooks come in various shapes and for different purposes, the orientation of the barbs also varies. This invention uses a servo motor 15 to adjust the rotation angle of the rotating shaft 14, thereby causing the pull line 19 to rotate at different angles. This allows the pull line 19 to be at different angles relative to the barbs, simulating the force state of the barbs under actual fishing conditions. In conjunction with the electric cylinder 110 driving the sliding block 13 to slide along the sliding groove 12, a specific tension can be applied to the pull line 19. The tension sensor 17 located on the upper part of the connecting frame 16 records the force state of the pull line 19. By conducting multiple tests on the same type of fishhook, the maximum bearing capacity of the barb position can be determined, further improving the overall performance evaluation of the fishhook. Currently, most fishhook tests only assess bending ability, while this invention improves product performance parameters through precise detection of the barb position, facilitating subsequent consumer purchases.

[0037] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown in the figure, this invention proposes a novel composite material fishhook strength testing device, including a side fixing component 2 and a bottom fixing component 3. The side fixing component 2 is disposed outside the tension component 1 and is configured to fix the side of the fishhook. The bottom fixing component 3 is disposed below the side fixing component 2 and is configured to fix the bottom of the fishhook to prevent the fishhook from shaking during the testing process.

[0038] The side fixing assembly 2 includes a first fixing platform 21, a moving port 22, a cylinder 23, a push rod 24, a moving groove 25, a horizontal support 26, a pressure plate 27, a telescopic device 28, a pressing column 29, a hydraulic device 210, a hydraulic rod 211, and a limiting plate 212.

[0039] The bottom fixing component 3 includes a second fixing platform 31, a placement groove 32, a sliding device 33, a slide rail 34, a sliding component 35, and a limiting post 36.

[0040] In this embodiment of the invention, a movable opening 22 is provided in the middle of the first fixed platform 21, and hydraulic devices 210 are symmetrically provided on both sides of the movable opening 22. The hydraulic devices 210 are fixed inside the first fixed platform 21. A hydraulic rod 211 is provided at the front end of each hydraulic device 210, and the two sets of hydraulic rods 211 are arranged opposite to each other. A limiting plate 212 is provided at the end of each hydraulic rod 211. The limiting plate 212 is located at the bottom of the movable opening 22. The side of the fishhook to be tested, i.e. the position away from the needle, needs to be placed between the limiting plates 212. The hydraulic device 210 can extend and retract the hydraulic rods 211. As the hydraulic rods 211 extend and retract, they can eventually drive the limiting plates 212 to move relative to each other. The fishhook placed between the limiting plates 212 will be fixed firmly.

[0041] Multiple sets of cylinders 23 are provided on the upper part of the first fixed platform 21. Each cylinder 23 is symmetrically arranged on the outer surface of the first fixed platform 21 with the moving port 22 as the axis. Each cylinder 23 has a push rod 24 at its lower part. A moving groove 25 is provided inside the first fixed platform 21 below the push rod 24. A horizontal support 26 is connected to the bottom end of the push rod 24. The bottom of the horizontal support 26 is movably set inside the moving groove 25 by means of a cylinder. By changing the extension and retraction of the push rod 24 by the cylinder 23, the horizontal support 26 can be moved along the moving groove 25. A pressure plate 27 is provided at the bottom of the horizontal support 26, facing the inside of the moving port 22. When the horizontal support 26 moves downward, it will drive the pressure plate 27 to move downward with it. The pressure plate 27 can hold the fish placed on the limiting plate 212. The hook is fixedly connected to the middle of the outer surface of the horizontal support 26, and a telescopic device 28 is fixedly connected to the middle of the telescopic device 28. A pressing column 29 is provided inside the telescopic device 28. A pressing cylinder is provided at the end of the pressing column 29. The pressing column 29 also faces the inside of the moving port 22. The telescopic device 28 can control the pressing column 29 to extend and retract back and forth. When the pressure plate 27 abuts against the fish hook in the middle of the limiting plate 212, the telescopic device 28 controls the pressing column 29 to move into the moving port 22. As the pressing column 29 moves, the fish hook can be pressed tightly against the bottom of the moving port 22. Through the limiting effect of the pressing column 29, the pressure plate 27 and the limiting plate 212, the fish hook can be firmly fixed inside the moving port 22, preventing the problem of shaking during the testing and stretching process, and thus making the final test result more accurate.

[0042] A placement groove 32 is also provided in the middle of the second fixed platform 31. Sliding devices 33 are symmetrically arranged on both sides of the placement groove 32, and each sliding device 33 has a slide rail 34 inside. A sliding component 35 is movably arranged inside each slide rail 34. The sliding device 33 can control the sliding component 35 to move up and down along the slide rail 34. A limiting post 36 is provided inside the sliding component 35. The sliding component 35 can control the limiting post 36 to extend and retract. The two sets of sliding components 35 are arranged opposite to each other. So when the sliding component 35 controls the limiting post 36 to extend and retract, when the two sets of limiting posts 36 move outward at the same time, the ends of the two sets of limiting posts 36 will eventually fit together to form a complete cylinder.

[0043] Once the fishhook is securely fixed by the side fixing component 2, the bottom of the fishhook is now placed inside the placement groove 32. Figure 1As shown, the sliding component 35 then controls the limiting post 36 to move outward. When the ports of the two sets of limiting posts 36 are connected, the sliding component 35 stops operating. Then, the sliding device 33 controls the sliding component 35 to move downward. As the sliding component 35 moves downward, the limiting post 36 can finally press the fishhook firmly against the bottom of the placement groove 32. Finally, through the fixing of the side fixing component 2 and the bottom fixing component 3, the fishhook can be firmly fixed inside the moving port 22 and the placement groove 32, and the problem of the fishhook shaking during the stretching process is avoided, thus improving the final test results.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0045] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
