A lightweight fishing hook that is easy to extend and adjust.

Abstract

This utility model relates to a lightweight fishing hook that is easy to extend and adjust, including a sleeve, a sliding member, a fishhook, and an adaptive barb. The sliding member is installed at the bottom of the sleeve, and the fishhook is fixedly installed at the bottom. The adaptive barb is installed on the surface of the fishhook. When the length needs to be adjusted, the rotating seat is disengaged from a threaded part on the surface of the sleeve, and the shell is moved. The sliding groove inside the shell slides on the surface of the sliding block, which limits the shell. The rotating seat is threaded to another threaded part on the surface of the sleeve, so that the shell is fixed on the surface of the sleeve, which has an extension function. When the fishhook is used to hook a fish, the three barbs will penetrate into the fish's body along the direction of the fishhook's movement. When the fish struggles, the barbs will rotate in the side groove, adapting to the fish's struggle and preventing the fish from slipping. When the fishhook is not hooking a fish, the push plate will push the three barbs back to their original position under the action of the spring, that is, the angle between the three barbs and the surface of the fishhook is the smallest, which is convenient for the next use.

Description

Technical Field

[0001] This utility model relates to the field of fishing gear, specifically a lightweight fishing hook that is easy to extend and adjust. Background Technology

[0002] In fishing activities, fishing tackle serves as an aid in hook removal and fishing hook preparation. Its performance directly affects fishing efficiency and fish protection. Traditional fishing tackle usually uses a fixed barb structure for the hook part. However, the anti-loosening effect of the fixed barb is limited during the hooking process. When a fish is hooked, it will struggle violently and twist its body constantly. The fixed barb is difficult to adapt to the dynamic changes of the fish's body.

[0003] For example, a fishing hook disclosed in the authorized patent document with application number CN202121227516.1 includes a handle tube, an inner tube, and a top cover. The inner tube is fitted inside the handle tube, the upper end of the handle tube is fixed to the top cover, and the lower end of the inner tube is connected to the fish hook. A weighing device is provided in the inner cavity of the inner tube. When a fish is hooked, it will struggle violently and twist its body continuously. The fixed barb is difficult to adapt to the dynamic changes of the fish's body. That is, the fixed barb mentioned above is difficult to adapt to the dynamic changes of the fish's body and can easily slip off the barb, causing the angler to miss the catch and affecting the fishing experience. Therefore, we need to provide a lightweight fishing hook that is easy to extend and adjust. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight fishing hook that is easy to extend and adjust. The hook has an adaptive barb inside, which allows the three barbs on the hook to adjust their angles as the fish struggles after being hooked, making it difficult for the fish to fall off. When the fish struggles, it squeezes the barbs, causing the three barbs to automatically adjust their angles to fit the contour of the fish's body, increasing the contact area and friction, forming a multi-angle clamping effect, reducing the risk of slippage. The barbs can dynamically adjust their angles with the fish's body, avoiding the hard piercing of fixed barbs, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight fishing hook that is easy to extend and adjust, comprising:

[0006] A sleeve, a slider, a fishhook, and an adaptive barb assembly are provided. The slider is installed at the bottom of the sleeve, and a fishhook is fixedly installed at the bottom. The adaptive barb assembly is installed on the surface of the fishhook so that the barb can extend outward after hooking a fish.

[0007] The adaptive barb includes a groove, a pusher, side grooves, and barbs. The three barbs are evenly distributed on the surface of the fishhook, and the barbs are rotatably installed inside. The groove is opened inside the fishhook and communicates with the three side grooves. The pusher is located inside the groove and is used to assist in pressing the three barbs.

[0008] Preferably, the pushing member includes a spring and a push plate, the push plate being slidably mounted in the groove, and the spring being installed between the bottom of the push plate and the groove.

[0009] Preferably, the top of the push plate has an annular beveled section.

[0010] Preferably, the sliding component includes a sliding base, a long rod, and a weighing component. The sliding base is slidably installed inside the sleeve, and the long rod is fixedly installed inside. The lower end of the long rod passes through the bottom of the sleeve and is fixedly installed with the fishhook.

[0011] Preferably, the weighing component includes a spring, a scale groove, and a limiting nut. The spring is movably sleeved on the surface of the long rod and is located between the bottom of the inner wall of the sleeve and the bottom of the slide block. The surface of the long rod is provided with a scale groove, and the top of the sleeve is provided with a limiting nut that is threaded onto the surface of the long rod.

[0012] Preferably, a limiting seat is fixedly installed between the long rod and the fishhook to restrict the upward movement of the long rod.

[0013] Preferably, it also includes an extension component, which includes a housing, a limiting component, and a rotating seat. The housing is movably sleeved on the surface of the sleeve, and the rotating seat is rotatably mounted on the bottom. The surface of the sleeve is integrally machined with two threaded portions that are threaded to the inner wall of the rotating seat. The limiting component is installed between the housing and the sleeve to prevent the housing from falling off.

[0014] Preferably, the limiting member includes a slider and a groove, with two sliders symmetrically distributed on the surface of the sleeve, and a groove for sliding of the slider is provided inside the housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features an adaptive barb inside the fishhook. After hooking a fish, the fish's struggles cause the three barbs on the hook to adjust their angles, making it difficult for the fish to fall off. When the fish struggles, it squeezes the barbs, causing the three barbs to automatically adjust their angles to fit the fish's body contour, increasing the contact area and friction, forming a multi-angle clamping effect, and reducing the risk of slippage. The barbs can dynamically adjust their angles with the fish's body, avoiding the hard piercing of fixed barbs. Attached Figure Description

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

[0024] Please see Figure 1-5 This utility model provides a technical solution: a lightweight fishing hook that is easy to extend and adjust, comprising:

[0025] Sleeve 1, slider 2, fish hook 3 and adaptive barb 4. Slider 2 is installed at the bottom of sleeve 1, fish hook 3 is fixedly installed at the bottom, and adaptive barb 4 is installed on the surface of fish hook 3 so that the barb can extend outward after hooking a fish.

[0026] The adaptive barb part 4 includes a groove 41, a pusher 42, a side groove 43 and barbs 44. The three barbs 44 are evenly distributed on the surface of the fishhook 3 and are rotatably installed inside. The groove 41 is opened in the fishhook 3 and communicates with the three side grooves 43. The pusher 42 is located in the groove 41 and is used to assist in pressing the three barbs 44.

[0027] Specifically, the fishhook 3 is equipped with an adaptive barb 4, which allows the three barbs 44 on the fishhook 3 to adjust their angles when the fish struggles after being hooked, making it difficult for the fish to fall off. When the fish struggles, it will squeeze the barbs 44, causing the three barbs 44 to automatically adjust their angles to fit the contour of the fish, increasing the contact area and friction, forming a multi-angle clamping, reducing the risk of slippage. The barbs 44 can dynamically adjust their angles with the fish, avoiding the hard piercing of the fixed barbs 44.

[0028] The pusher 42 includes a spring 421 and a push plate 422. The push plate 422 is slidably installed in the groove 41, and the spring 421 is installed between the bottom and the groove 41.

[0029] Furthermore, the spring 421 is made of 60Si2Mn spring steel with a diameter of 0.8-1.2mm. In the free state, the top of the push plate 422 is in contact with the bottom of the barb 44. When the barb 44 is squeezed and rotated by the fish, the bottom of the barb 44 slides along the annular inclined surface of the push plate 422, pushing the push plate 422 to compress the spring 421. After the fish is separated, the spring 421 resets and drives the push plate 422 to move upward, forcing the barb 44 to rotate back to the initial angle. This structure uses the elasticity of the spring 421 to realize the automatic reset of the barb 44, which solves the cumbersome problem of the traditional barb 44 needing to be manually reset. The spring steel material ensures that it still maintains stable elasticity after more than 10,000 deformations.

[0030] The top of the push plate 422 has an annular beveled section;

[0031] The beveled surface has an inclination angle of 15°-20° and is polished (Ra≤0.8μm). When the barb 44 rotates, the beveled surface and the bottom of the barb 44 form rolling friction with a friction coefficient ≤0.15, which reduces the jamming when adjusting the barb 44.

[0032] The sliding component 2 includes a sliding base 21, a long rod 22 and a weighing component 23. The sliding base 21 is slidably installed inside the sleeve 1, and the long rod 22 is fixedly installed inside. The lower end of the long rod 22 passes through the bottom of the sleeve 1 and is fixedly installed with the fish hook 3.

[0033] It is worth noting that the slide block 21 and the long rod 22 are integrally formed from 304 stainless steel. The outer diameter of the slide block 21 is 0.1-0.2mm smaller than the inner diameter of the sleeve 1, and the fitting clearance is controlled at 0.05-0.1mm. A fluororubber sealing ring is installed where the long rod 22 passes through the sleeve 1 to prevent water and mud from entering the interior of the sleeve 1. When the fish hook 3 is under force, the long rod 22 drives the slide block 21 to slide linearly along the inner wall of the sleeve 1, solving the problem of easy jamming in traditional telescopic structures. The stainless steel material and the sealing ring improve the corrosion resistance of the device.

[0034] The weighing component 23 includes a spring 231, a scale groove 232 and a limiting nut 7. The spring 231 is movably sleeved on the surface of the long rod 22 and is located between the bottom of the inner wall of the sleeve 1 and the bottom of the slide block 21. The scale groove 232 is provided on the surface of the long rod 22, and the top of the sleeve 1 is provided with a limiting nut 7 that is threaded onto the surface of the long rod 22.

[0035] It should be noted that the spring 231 of the weighing component 23 is made of 50CrVA alloy with a stiffness coefficient of 5-8 N / mm. The accuracy of the scale groove 232 is ±50g, and the weighing range is set to 0-5kg. When the fish weight exceeds 5kg, the bottom of the slide 21 contacts the bottom of the inner wall of the sleeve 1 to form a mechanical limit, preventing the spring 231 from being damaged by overload. This design solves the problem of needing to carry an extra scale when fishing. The material of the spring 231 ensures that the weighing error is ≤3%, meeting daily estimation needs.

[0036] A limiting seat 5 is fixedly installed between the long rod 22 and the fish hook 3 to restrict the upward movement of the long rod 22;

[0037] Specifically, the limiting seat 5 is injection molded with PA66+30% glass fiber and is connected to the long rod 22 by interference fit (interference amount 0.02-0.05mm). The top is equipped with a rubber buffer pad. When the long rod 22 moves upward, the limiting seat 5 contacts the bottom of the sleeve 1. The rubber pad can absorb the impact energy and avoid direct collision of metal parts to prevent abnormal noise and wear.

[0038] It also includes an extension 6, which includes a housing 61, a limiting member 62, and a rotating seat 63. The housing 61 is movably sleeved on the surface of the sleeve 1, and the rotating seat 63 is rotatably installed at the bottom. The surface of the sleeve 1 is integrally machined with two threaded portions that are threaded to the inner wall of the rotating seat 63. The limiting member 62 is installed between the housing 61 and the sleeve 1 to prevent the housing 61 from falling off.

[0039] Furthermore, the shell 61 of the extension component 6 is made of 7075 aluminum alloy with T6 treatment, which reduces the weight by 40% compared to a steel shell 61 of the same volume. The fit accuracy between the threads on the inner wall of the rotating seat 63 and the threaded part is 6H / 6g. When the rotating seat 63 switches between the two threaded parts, the straightness error of the slider 621 sliding along the slide groove 622 is ≤0.1mm / m, ensuring smooth extension and retraction of the shell 61. This structure solves the problem that the fixed length of the fishing device cannot adapt to different scenarios, and the aluminum alloy material and the limiting structure work together to improve portability and stability.

[0040] The limiting member 62 includes a slider 621 and a groove 622. The two sliders 621 are symmetrically distributed on the surface of the sleeve 1, and the groove 622 for sliding of the sliders 621 is provided in the housing 61.

[0041] The slider 621 is made of TC4 titanium alloy, and the inner wall of the groove 622 is bonded with a 0.1mm thick polytetrafluoroethylene film, with a sliding friction coefficient ≤0.05. The slider 621 is fixed to the sleeve 1 by laser welding, with a welding strength ≥200MPa. Limiting bosses are provided at both ends of the groove 622 to prevent the housing 61 from detaching from the sleeve 1. The titanium alloy slider 621 mates with the polytetrafluoroethylene film.

[0042] All threaded mounting surfaces in this application utilize a modified triangular thread with a self-locking function. The thread helix angle is designed to be 1.5°-2.5° to enhance the anti-loosening effect. After phosphating, the thread surface is coated with an 8-12μm Dacromet coating and impregnated with silicone sealant to form a sealing layer, resulting in excellent corrosion resistance. In addition, the thread can effectively expel dust, and it can still be used normally even if a small amount of dust adheres to it.

[0043] When the length of this device needs to be adjusted, the rotating seat 63 is disengaged from a threaded part on the surface of the sleeve 1, and the housing 61 is moved. The sliding groove 622 inside the housing 61 slides on the surface of the slider 621, which limits the housing 61. The rotating seat 63 is then threaded onto another threaded part on the surface of the sleeve 1, thus fixing the housing 61 to the surface of the sleeve 1 and providing an extension function. When the fishhook 3 is used to hook a fish, the three barbs 44 will penetrate the fish's body along the direction of the fishhook 3's movement. When the fish struggles, the barbs 44 will rotate in the side groove 43, adapting to the fish's struggle to prevent the fish from slipping. When the fishhook 3 is not hooking a fish, the push plate 422 will push the three barbs 44 back to their original position under the action of the spring 421, that is, the angle between the three barbs 44 and the surface of the fishhook 3 is minimized, making it convenient for the next use. When it is necessary to weigh the fish, rotate the limiting nut 7 to separate the limiting nut 7 from the long rod 22. The long rod 22 can move with the slide 21 inside the sleeve 1. When the sleeve 1 is placed vertically, the weight of the fish will cause the slide 21 to move down, compressing the spring 231 and causing the long rod 22 to move down. The surface of the long rod 22 is provided with a scale groove 232, which can be used to roughly read the weight of the fish. When not in use, the top of the long rod 22 is threaded onto the limiting nut 7 to prevent the long rod 22 from moving down. A column is provided at the connection between the long rod 22 and the fish hook 3 to limit the upward movement of the long rod 22 and fix the long rod 22. The sleeve 1 and the shell 61 are both provided with multiple slots and holes to achieve lightweighting. The spring 231 is set as a corrosion-resistant spring 231. Cleaning rings are fixedly installed on the top and bottom of the slide 21, and the surface of the cleaning rings is in contact with the inner wall of the sleeve 1.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
