Description

Technical Field

[0001] This utility model relates to a retrieval device, and more specifically, to a lockable and secure flexible retrieval hook. Background Technology

[0002] When recovering underwater objects, a retrieval tool or flexible rope is needed to hook the head or tail of the object to adjust its swaying amplitude, ensuring a smooth retrieval process. Currently used retrieval tools generally have fixed hooks; bent hooks cannot be easily stored, taking up considerable space and making storage inconvenient.

[0003] Chinese invention patent CN114919721A discloses a flexible hook-type retrieval device. The retrieval hook can be adjusted for straightening and bending, facilitating easy storage of the device. During normal use, the flexible rope typically needs to be pulled taut with one hand to maintain the hook's bent state. Maintaining the taut rope is essential for proper operation; if the rope slackens, the hook will straighten, rendering it unusable and causing inconvenience during use.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flexible fishing hook that can be locked and fixed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lockable and fixed flexible retrieval hook includes a retrieval rod, a retrieval hook, and a flexible rope. The retrieval hook is connected to the lower end of the retrieval rod and includes several chain links. Each chain link is hinged in sequence to form a chain-like structure, having both a straight and a bent state. The two ends of each chain link are a first section and a last section, respectively. The first section is fixedly connected to the lower end of the retrieval rod, and the last section is away from the retrieval rod. The outer sides of each chain link are rotatably connected by a hinge structure, and the inner side of each chain link has a through hole. The first end of the flexible rope is fixedly connected to the last section of each chain link, and the flexible rope passes through the through hole of each chain link in sequence. The second end of the flexible rope extends from the lower end of the retrieval rod and extends out from the upper end opening of the retrieval rod.

[0008] The upper end of the retrieval rod is provided with a notch, and clamping blocks are fixedly connected to both sides of the notch. A tapered part is formed on the outer periphery of the upper end of the retrieval rod, and the outer diameter of the tapered part gradually increases from the lower end to the upper end.

[0009] It also includes an adjusting sleeve, which is fitted over the retrieval rod. The adjusting sleeve can be partially fitted over the conical part. The adjusting sleeve moves toward the upper end of the retrieval rod to press against and push the conical part. The clamping blocks on both sides of the notch groove move closer to each other to clamp and fix the flexible rope.

[0010] The present invention is further configured such that the link has an inner side and an outer side facing away from each other, and the width of the outer side of the link is greater than the width of the inner side.

[0011] The present invention is further configured such that the two ends of the link form a first end face and a second end face respectively, the first end face and the second end face have a wedge-shaped structure and are inclined toward each other inward.

[0012] The present invention is further configured such that, when the fishing hook shown is in a bent state, the first end face and the second end face of the adjacent chain links abut against each other.

[0013] The present invention is further configured such that a limiting groove is formed on the first end face, and a limiting block is fixed on the second end face, so that the limiting grooves and limiting blocks of adjacent links can be mutually fitted and limited.

[0014] The present invention is further configured such that a first hinge portion is provided on the outer side of the first end face, and a second hinge portion is provided on the outer side of the second end face, and the first hinge portion and the second hinge portion are hinged to each other.

[0015] The present invention is further configured such that a stop block is fixedly connected to the outside of the tapered part of the retrieval rod, and the stop block can block and limit the adjustment sleeve.

[0016] The present invention is further configured such that a pressing part is fixedly connected to the inner circumference of the adjusting sleeve in the direction of the upper end, the adjusting sleeve moves in the direction of the upper end of the retrieval rod, the pressing part can press against the conical part, and move closer to each other in the direction of the limiting groove, and the two pressing parts can clamp the flexible rope.

[0017] The present invention is further configured to include a sleeve, which is fitted over the fishing rod and can slide up and down along the fishing rod. The adjusting sleeve is fitted and connected to the outer periphery of the end of the sleeve.

[0018] The present invention is further configured such that the inner circumference of the adjusting sleeve is threadedly connected to the outer circumference of the sleeve, and the extension and retraction can be achieved by adjusting the thread.

[0019] In summary, this utility model has the following beneficial effects:

[0020] Each link has a first link and a last link at its two ends. The first link is fixedly connected to the lower end of the fishing rod, while the last link is away from the fishing rod. Each link is suspended, allowing for flexible movement. When the fishing hook is extended, each link is roughly extended, and the fishing rod and hook can be roughly extended and stored in a sleeve. When the fishing hook is bent, it forms a hook-like structure, facilitating fishing operations.

[0021] By adjusting the adjusting sleeve, it can be moved upwards. The inner pressing part of the adjusting sleeve presses against the conical part, clamping and fixing the flexible rope, thus maintaining the retrieval hook in a bent state and enabling normal retrieval. In use, the operator holds the sleeve, and the retrieval rod, retrieval hook, and other components, which, under their own weight, tend to move downwards. This causes the conical part at the upper end of the retrieval rod to move downwards relative to the adjusting sleeve. The pressing part presses against the outer circumference of the conical part, applying a force inwards. Guided by the conical part, the vertical force is converted into a lateral force, pushing the clamping block closer together, thus maintaining the clamping effect on the flexible rope. Furthermore, the greater the weight of the object being retrieved, the greater the pressure on the outer side of the conical part, and the greater the clamping force on the flexible rope, thus maintaining the flexible rope in a stable state and keeping the retrieval hook stably bent.

[0028] 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.

[0029] This embodiment discloses a lockable and fixed flexible retrieval hook, referring to... Figures 1-5 As shown, it includes a salvage rod 1, a salvage hook 2 and a flexible rope 3. The salvage hook 2 is connected to the lower end 11 of the salvage rod 1. The salvage hook 2 includes several chain links 21, which are sequentially hinged to form a chain-like structure and have a straight state and a bent state.

[0030] Each link 21 has a first link 22 and a last link 23 at its two ends. The first link 22 is fixedly connected to the lower end 11 of the retrieval rod 1, and the last link 23 is away from the retrieval rod 1. Each link 21 is suspended, allowing for flexible movement. When the retrieval hook 2 is in a straight position, each link 21 is also roughly straight, allowing the retrieval rod 1 and retrieval hook 2 to be roughly straight and stored in the sleeve 4. When the retrieval hook 2 is bent, it forms a hook-like structure, facilitating retrieval operations.

[0031] The outer side 2002 of the link 21 is rotatably connected by the hinge structure 202. The inner side 2001 of the link 21 has a through hole 201. The first end of the flexible rope 3 is fixedly connected to the last section 23 of each link 21. The flexible rope 3 passes through the through hole 201 of the link 21 in sequence. The second end of the flexible rope 3 extends from the lower end 11 of the retrieval rod 1 and extends out from the opening at the upper end 12 of the retrieval rod 1.

[0032] When in use, by pulling the flexible rope 3, each link 21 of the flexible rope 3 can be bent, thereby allowing each link 21 to bend inward 2001 to form a complete hook structure.

[0033] Reference Figure 4 , Figure 5 As shown, a notch 121 is provided at the upper end 12 of the salvage rod 1, and clamping blocks 122 are fixedly connected to both sides of the notch 121. The clamping blocks 122 on both sides of the notch 121 can deform towards each other in the direction of the inward side of the notch 121, thereby narrowing the width of the notch 121. The flexible rope 3 passes through the notch 121. In the initial state, the notch 121 allows the flexible rope 3 to move normally; after narrowing, the clamping blocks 122 on both sides of the notch 121 can clamp and fix the flexible rope 3.

[0034] A tapered portion 123 is formed on the outer periphery of the upper end 12 of the salvage rod 1. The outer diameter of the tapered portion 123 gradually increases from the lower end 11 to the upper end 12, i.e., refer to Figure 5 The outer diameter of the tapered part 123 has a structure that is larger at the top and smaller at the bottom.

[0035] The flexible retrieval hook in this embodiment also includes an adjusting sleeve 5, which is fitted over the retrieval rod 1 and can be partially fitted over the conical portion 123. The adjusting sleeve 5 moves toward the upper end 12 of the retrieval rod 1 and can press against and push the conical portion 123. The clamping blocks 122 on both sides of the notch 121 move closer to each other and can clamp and fix the flexible rope 3.

[0036] A stop 124 is fixedly connected to the outside of the tapered part 123 of the salvage rod 1. The stop 124 is located closer to the upper end and can block and limit the adjustment sleeve 5.

[0037] A pressing part 51 is fixedly connected to the inner circumference of the adjusting sleeve 5 in the direction of the upper end 12. The adjusting sleeve 5 moves in the direction of the upper end 12 of the retrieval rod 1. The pressing part 51 can press against the conical part 123 and move closer to each other in the direction of the limiting groove 2111. The two pressing parts 51 can clamp the flexible rope 3.

[0038] In use, by adjusting the adjusting sleeve 5, the adjusting sleeve 5 is moved upwards. The pressing part 51 inside the adjusting sleeve 5 can press and push the conical part 123, which can clamp and fix the flexible rope 3, thereby keeping the retrieval hook 2 in a bent state, and thus enabling normal retrieval.

[0039] Reference Figure 4 , Figure 5 As shown, the flexible retrieval hook in this embodiment also includes a sleeve 4. The sleeve 4 is sleeved on the outside of the retrieval rod 1 and can slide up and down along the retrieval rod 1. The sleeve 4 has a relatively long length. When the retrieval hook 2 is in the straightened state, the sleeve 4 can be slid down and adjusted to retract the retrieval hook 2 into the sleeve 4.

[0040] The adjusting sleeve 5 is fitted onto the outer periphery of the end of the sleeve 4, connecting the sleeve 4 and the adjusting sleeve 5 as a single unit. In use, holding the outer periphery of the sleeve 4 allows the weight of gravity and the weight of the object being retrieved to exert a downward force on the retrieval hook 2. The sleeve 4 moves upward relative to the retrieval rod 1, causing the adjusting sleeve 5 to press against the outer periphery of the conical portion 123. Guided by the conical portion 123, the vertical force is converted into a lateral force, pushing the clamping block 122 towards a closer direction, thus maintaining the clamping effect on the flexible rope 3. Furthermore, the greater the weight of the object being retrieved, the greater the pressure on the outer side of the conical portion 123, and the greater the clamping force applied to the flexible rope 3, thus maintaining the flexible rope 3 in a stable state and keeping the retrieval hook 2 stably bent.

[0041] Specifically, the inner circumference of the adjusting sleeve 5 is threadedly connected to the outer circumference of the sleeve 4. The extension and retraction can be achieved through thread adjustment, thereby enabling directional adjustment and facilitating the extension and retraction adjustment of the overall length of the sleeve 4 and the adjusting sleeve 5.

[0042] Additionally, refer to Figures 1-3 As shown, link 21 has an inner side 2001 and an outer side 2002 facing away from each other. The inner side 2001 is the inner direction of the bending of the fishing hook 2. The width of the outer side 2002 of link 21 is greater than the width of the inner side 2001. The two ends of link 21 form a first end face 211 and a second end face 212, respectively. The first end face 211 and the second end face 212 have a wedge-shaped structure and are inclined towards the inner side 2001.

[0043] A first hinge portion 2021 is provided on the outer side of the first end face 211, and a second hinge portion 2022 is provided on the outer side of the second end face 212. The first hinge portion 2021 and the second hinge portion 2022 are hinged to each other, so that adjacent links 21 can deflect smoothly and stably.

[0044] The flexible rope 3 is threaded through the link 21 near the inner side 2001, so that when the flexible rope 3 is pulled, it can apply a bending force to each link 21, so that each link 21 can be bent into a hook-shaped structure.

[0045] Furthermore, a limiting groove 2111 is formed on the first end face 211, and a limiting block 2121 is fixed on the second end face 212. The limiting grooves 2111 and the limiting blocks 2121 of adjacent links 21 can be mutually engaged and limited. By engaging the limiting grooves 2111 and the limiting blocks 2121, the structural stability of adjacent links 21 can be maintained. In a bent state, the limiting grooves 2111 and the limiting blocks 2121 can be stably engaged, thereby resisting greater lateral forces and maintaining the structural stability of the hook-shaped structure.

[0046] In addition, to improve the structural stability between the adjusting sleeve and the retrieval rod, a threaded hole can be made on the outer circumference of the sleeve, with a screw threaded into the hole. The screw is positioned perpendicular to the retrieval rod. When tightening is required, the screw can be turned so that its end abuts against the outer circumference of the retrieval rod, achieving a locking and securing effect. This maintains the positional stability of the adjusting sleeve and the retrieval rod, and stably keeps the retrieval hook in a bent state.

[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
