Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of rescue hooks, in particular to a kind of multi-dimensional water area vector rescue hook. BACKGROUND

[0002] Water area rescue hook is a kind of rescue tool specially designed for fast, safe hooking and fixing target in water environment. Its efficient hooking capacity and flexible operation mode can significantly improve rescue efficiency and reduce rescue risk. However, the water area rescue hook on the market currently adopts fixed three-pronged hook design, which has the following inherent shortcomings:

[0003] Inconvenient to carry, the structure of fixed three-pronged hook is relatively bulky, and it occupies a large space, which is inconvenient for rescue personnel to carry, especially in the case of needing to respond quickly, the inconvenience of carrying may delay the rescue opportunity.

[0004] Risk of easy unhooking, due to lack of effective locking structure, fixed three-pronged hook is easy to unhook after hooking the target due to water flow impact, target struggle or improper operation, etc., which leads to rescue failure or secondary injury. INVENTION CONTENTS

[0005] In order to solve the above technical problems, the utility model provides a kind of multi-dimensional water area vector rescue hook.

[0006] In order to solve the above technical problems, the utility model adopts the technical scheme: a kind of multi-dimensional water area vector rescue hook, including hook main body, the hook claw that is hinged on the hook main body, and the torsional spring that is connected on the hook claw;

[0007] In use state, the hook claw is close to the end of the hook main body and abuts on the hook main body, the torsional spring is connected on the end of the hook claw away from the hook main body, and the torsional spring elastically abuts on the hook main body.

[0008] Further, the hook main body is provided with a hook claw installation slot accommodating the hook claw, and a main body center hole for passing through a rescue rope.

[0009] Further, the hook claw is installed on the hook claw installation slot of the hook main body through a pin, the pin is passed between the cylindrical pin hole on the hook main body and the hook claw cylindrical pin hole on the hook claw, and the hook claw is rotatably arranged on the hook main body through the pin.

[0010] Further, the hook claw has three, and the three hook claws are evenly distributed on the hook main body in circumferential direction.

[0011] Further, the torsional spring is installed on the hook claw through a torsional spring installation hole, and one end of the torsional spring abuts on a torsional spring stop on the hook main body.

[0012] Furthermore, in the non-use state, the three hooks can be rotated and retracted to one side close to the hook body, and the torsion spring is compressed.

[0013] Furthermore, in use, the hook extends under the elastic force of the torsion spring, forming a clamping space between the hook, the torsion spring, and the hook body.

[0014] This utility model discloses a multi-dimensional water rescue hook, which adopts a folding structure and a torsion spring locking mechanism, aiming to optimize the shortcomings of existing water rescue hooks and improve their portability and safety, and has the following advantages:

[0015] The folding design enhances portability. When not in use, the rescue hook can be folded and stored, significantly reducing its size and making it easy for rescuers to carry. This design is particularly suitable for rescue scenarios requiring rapid response, significantly improving rescue efficiency. It also enhances operational flexibility; the folding structure allows the rescue hook to quickly enter working condition after unfolding, making operation simple and flexible, adapting to various rescue needs in complex aquatic environments.

[0016] An automatic locking mechanism is employed to achieve the automatic locking function. The torsion spring not only enables the unfolding and folding of the folding structure but also serves as the locking mechanism. When the rescue hook is engaged with a target, the torsion spring automatically locks the hook claw to prevent the target from detaching and ensure safety during the rescue process.

[0017] The anti-disengagement design and torsion spring locking mechanism can effectively cope with external interference such as water flow impact and target struggle, avoiding rescue failure or secondary injury caused by disengagement, and significantly improving the reliability and success rate of rescue.

[0018] In summary, by adopting a folding structure and a torsion spring locking mechanism, the inherent drawbacks of existing water rescue hooks—such as inconvenience in carrying and susceptibility to disengagement—are overcome. The folding structure enhances portability and operational flexibility, while the torsion spring locking mechanism ensures safety and reliability during rescue operations. This design not only optimizes the performance of the rescue hook but also provides a more efficient and safer solution for water rescue. It can be widely applied in scenarios such as water rescue, maritime search and rescue, and flood rescue, significantly improving rescue efficiency and reducing rescue risks, and possesses broad market prospects and social benefits.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] Example 1;

[0028] like Figure 1 The multi-dimensional water vector rescue hook shown includes a hook body 1, a hook claw 3, and a torsion spring 4. A portion of the hook body is a central tube, and another portion is a hook claw mounting groove 9 surrounding the central tube. The hook claw mounting groove 9 accommodates the hook claw 3. Specifically, the hook claw 3 is positioned via... Figure 2 and Figure 3 The pin 2 shown is installed on the hook claw mounting groove 9 of the hook body 1, and the pin 2 passes through the cylindrical pin hole 5 on the hook body 1 and... Figure 4 The hook 3 is rotatably mounted on the hook body 1 via the pin 2 between the cylindrical pin holes 6 on the hook 3 shown. Therefore, the hook 3 is hinged to the hook body 1. Figure 4 and 5 The torsion spring 4 shown is mounted on the hook claw 3 through the torsion spring mounting hole 7, and one end of the torsion spring 4 abuts against the torsion spring anti-reverse platform 10 on the hook body 1.

[0029] In use, such as Figure 1 As shown, the hook 3 unfolds under the elastic force of the torsion spring 4, forming a clamping space between the hook 3, the torsion spring 4, and the hook body 1. The end of the hook 3 that is hinged to the hook body 1 abuts against the hook body 1 to limit the unfolding angle of the hook 3. The torsion spring 4 is connected to the end of the hook 3 away from the hook body 1, and the torsion spring 4 elastically abuts against the torsion spring anti-reverse platform 10 of the hook body 1. Figure 1 The display shows the state of gradually approaching the torsion spring anti-reverse platform 10. When the hook 3 hooks the target object, the target object compresses the torsion spring 4 and slides into the clamping range of the hook 3. The torsion spring 4 automatically rebounds, locking the target object within the clamping range of the hook 3 to prevent the target object from getting off the hook.

[0030] When not in use, the three claws 3 can rotate and retract to the side closer to the hook body 1, compressing the torsion spring 4. It should be understood that the retraction of the claws 3 to the side closer to the hook body 1 requires external force and relies on rope for binding.

[0031] Therefore, the folding structure design enhances portability. By employing this structure, the rescue hook can be folded and stored when not in use, significantly reducing its size and making it easy for rescuers to carry. This design is particularly suitable for rescue scenarios requiring rapid response, significantly improving rescue efficiency. It also enhances operational flexibility; the folding structure allows the rescue hook to quickly enter working condition after unfolding, making operation simple and flexible, adapting to various rescue needs in complex aquatic environments. It solves the inherent shortcomings of existing water rescue hooks, such as being inconvenient to carry and prone to detachment. The folding structure improves portability and operational flexibility, while the torsion spring locking mechanism ensures safety and reliability during rescue operations. This design not only optimizes the performance of the rescue hook but also provides a more efficient and safer solution for water rescue.

[0032] Example 2;

[0033] Based on Embodiment 1, in this embodiment, the central tube of the hook body 1 has a central hole 8 for threading a rescue rope through it. The rescue rope passes through the central hole 8 and is knotted to ensure that the rescue hook will not fall off during use.

[0034] In this embodiment, there are three hooks, which are evenly distributed circumferentially on the hook body. In other embodiments, the number of hooks is not limited to three; it can also be two or four, depending on the load-bearing capacity required for the rescue.

[0035] In summary, this invention offers several advantages: portability, as the folding design allows the rescue hook to retract close to the hook body when not in use, making it easy to carry; enhanced safety, with the torsion spring's automatic locking function ensuring the target object remains within the hook's gripping range, improving rescue safety and reliability; and ease of operation, as the deployment and locking processes are automated, simplifying operation and adapting to various rescue needs in complex aquatic environments.

[0036] Meanwhile, by adopting a folding structure and a torsion spring locking mechanism, the inherent shortcomings of existing water rescue hooks—such as inconvenience in carrying and susceptibility to disengagement—are overcome. The folding structure enhances portability and operational flexibility, while the torsion spring locking mechanism ensures safety and reliability during rescue operations. This design not only optimizes the performance of the rescue hook but also provides a more efficient and safer solution for water rescue. It can be widely used in scenarios such as water rescue, maritime search and rescue, and flood rescue, significantly improving rescue efficiency and reducing rescue risks, and has broad market prospects and social benefits.

[0037] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
