Description

Technical Field

[0001] The present invention relates to the technical field of rope buckles, and more specifically, to a rope hook that is easy to install and grip, has a highly reliable connection, and is resistant to breakage.

Background Art

[0002] A rope hook is an accessory used to connect ropes, webbing, or wires and adjust their length and tension. Typically, one end of the rope hook is fixed to one rope segment, and the other end can be detachably assembled to another rope segment to connect the two rope segments. Alternatively, both ends of the rope hook can be detachably assembled to two rope segments to fix the rope segments, thereby solving the problem of insufficient length of a single rope segment and adjusting the length of the rope segment so that it can achieve clamping or compression of other objects.

[0003] [Technical Problem] Currently, most rope hooks on the market secure the rope by providing an opening at one end for inserting the rope, and a buckle at the other end of the rope hook, which is attached to another rope to secure it. Such rope hooks have a simple structure. During use, the rope at the fixed end is driven by external force, which eventually rotates the rope hook, causing the buckle to detach from the rope at the other end, resulting in damage to the rope hook connection. Furthermore, when conventional rope hooks are used, the force acting on them is mainly concentrated on the buckle part of the rope hook, and as the force acting on it increases, the rope hook tends to become overloaded and break, thereby shortening the lifespan of the rope hook. In addition, because the rope hook itself is small in size, after screwing the rope hook onto one rope, it is often necessary to grasp the entire rope hook and then hook it onto another rope. During this process, the operator's fingers can easily obstruct the buckle portion of the rope hook, making it difficult to attach the rope hook to the rope, or the rope may compress the operator's fingers, potentially causing injury to the operator's fingers and making it difficult to attach and connect the rope hook. [Overview of the project] [Problems that the invention aims to solve]

[0004] Therefore, in order to overcome the shortcomings, there is a need to provide a rope hook that facilitates installation and gripping, provides a reliable connection, and is resistant to breakage. [Means for solving the problem]

[0005] The rope hook includes a hook body, the upper part of which has a horizontally extending through-hole used to connect the first rope, the upper part of which protrudes above the through-hole to form a gripping handle, two restricting fins are provided on two opposing sides of the front surface of the hook body at positions corresponding to the upper part of the through-hole, the lower part of which is bent upward to form an elastic hook having a major arc shape, the inner surface of which cooperates with the hook body to form a locking groove for restraining the second rope, and the line connecting the center of the through-hole and the center of the locking groove extends vertically.

[0006] In one embodiment, the gripping handle is inclined toward the hook body where the elastic hook is located, and the side of the hook body facing away from the elastic hook has an inclined surface that slopes toward the side closer to the elastic hook, and this inclined surface smoothly transitions toward the gripping handle.

[0007] In one embodiment, the inner diameter of the through-hole adjacent to the gripping handle is larger than the inner diameter of the through-hole adjacent to the elastic hook portion.

[0008] In one embodiment, the thickness of the hook body between the gripping handle and the elastic hook gradually decreases in the direction toward the elastic hook, and the width of the hook body between the gripping handle and the elastic hook gradually decreases in the direction toward the elastic hook.

[0009] In one embodiment, the thickness of the end portion of the elastic hook is greater than the thickness of the connection portion between the elastic hook and the hook body, and the width of the end portion of the elastic hook is smaller than the width of the connection portion between the elastic hook and the hook body.

[0010] In one embodiment, the locking groove has a teardrop shape, and the opening of the locking groove is located at the top of the teardrop shape.

[0011] In one embodiment, a retraction hole is provided in the middle portion of the hook body, extending from the top to the bottom, passing through the front and back sides, and the width of the upper part of the retraction hole is greater than the width of the lower part of the retraction hole.

[0012] In one embodiment, the side surface of the limiting fin adjacent to the through hole is provided with an arcuate surface that follows the inner contour of the through hole.

[0013] In one embodiment, the outer contour of the gripping handle is a smooth arc shape, and the end face of the elastic hook is concave to form an operating portion.

[0014] In one embodiment, the hook body, gripping handle, and elastic hook are integrally formed.

[0015] The rope hook of this invention is implemented such that a line connecting the center of the through hole and the center of the locking groove extends vertically. When the first rope is fixed and the tension of the second rope increases, the tension acting on the rope hook is evenly distributed to the connection between the elastic hook and the hook body and to the hook body itself. As the force increases, the elastic hook deforms, and the opening of the locking groove expands until the second rope falls out of the locking groove, thereby preventing the problem of damage to the rope hook caused by partial overloading of the roll hook and extending the service life of the rope hook. By placing limiting fins on both sides of the hook body, when the second rope is subjected to force in the front-rear direction, the limiting fins come into contact with the first rope, thereby preventing the first rope from driving the rope hook and rotating around the first rope, avoiding the problem of damage to the connection between the rope hook and the rope caused by the rotation of the rope hook and improving the stability of the connection between the rope hook and the rope. By positioning the gripping handle on the top of the hook body, a gripping portion is provided when the rope hook is connected to the rope, thereby reducing injuries to the fingers caused by rope compression, making it easier to fasten with the hook, and thereby reducing the difficulty of connecting the rope hook to the rope.

[0017] To make the above-mentioned objectives, features, and advantages of the present invention easier to understand, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following description includes many specific details to facilitate a complete understanding of the present invention. However, the present invention can be carried out in many ways other than those described herein, and those skilled in the art can make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Referring to Figures 1 and 6, the present invention discloses a rope hook that is easy to attach and grip, provides a reliable connection, and is resistant to breakage. The rope hook can be used to connect and restrict mesh ropes on the front or side of a backpack, and can also be used independently to connect and secure storage ropes. Specifically, the rope hook includes a hook body 100, a gripping handle 200 located on the upper part of the hook body 100, and an elastic hook 300 located on the lower part of the hook body 100. In this embodiment, the hook body 100, the gripping handle 200, and the elastic hook 300 are made from the same material. Preferably, the hook body 100, the gripping handle 200, and the elastic hook 300 are all made from a plastic or metal material that can undergo elastic deformation. For example, the hook body 100, the gripping handle 200, and the elastic hook 300 are made from plastic materials such as POM, nylon, PE, PET, PC, PVC, or PP. Furthermore, in this embodiment, the hook body 100, the gripping handle 200, and the elastic hook 300 are integrally formed. Depending on the material to be processed, the hook body 100, the gripping handle 200, and the elastic hook 300 can be integrally formed using methods such as injection molding. In other words, in this embodiment, the rope hook is an independent, integral component made from a single material.

[0019] Furthermore, referring to Figures 1 to 6, in this embodiment, the upper part of the hook body 100 is provided with a through hole 110 extending horizontally to receive the first rope 10. The upper part of the hook body 100 protrudes above the through hole 110 to form a gripping handle 200, and two restricting fins 120 are provided on each of the two opposing sides of the front surface of the hook body 100 at a position corresponding to the upper part of the through hole 110. Preferably, the restricting fins 120 have an arcuate surface adjacent to the through hole 110 along the inner contour of the through hole 110, and after the first rope 10 is tightened, it comes into contact with the arcuate surface of the restricting fins 120 to prevent relative sliding between them. The lower part of the hook body 100 is bent upward to form an elastic hook 300 having an arcuate shape. The elastic hook 300 and the inner surface of the hook body 100 constitute a locking groove 310 for restraining the second rope 20. The line connecting the center of the through-hole 110 and the center of the locking groove 310 extends vertically. In other words, the locking groove 310 is located directly below the through-hole 110. Preferably, the center of the through-hole 110, the center of the locking groove 310, and the center of gravity of the rope hook lie on the same straight line. In this embodiment, the front side of the hook body 100 is the side facing the operator when the rope hook is positioned in the front view, the back side of the hook body 100 is the side facing away from the operator when the rope hook is positioned in the side view, the side of the hook body 100 is the side facing the operator or the side facing away from the operator when the rope hook is positioned in the front view, the horizontal direction indicates the width direction of the hook body 100, i.e., the left-right direction in the front view, the front-back direction indicates the thickness direction of the hook body 100, i.e., the left-right direction in the side view, and the vertical direction indicates the height direction of the hook body 100, i.e., the up-down direction in the front view.

[0020] The aforementioned rope hook extends in the vertical direction by restricting the line connecting the center of the through hole 110 and the center of the locking groove 310. When the first rope 10 is fixed and the tension applied to the second rope 20 in the direction away from the first rope 10 increases, the elastic hook 300 is pulled, and the tensile force acting on the rope hook is evenly distributed across the connection portion between the elastic hook 300 and the hook body 100 and across the hook body 100. As the force increases, the elastic hook 300 deforms, and the distal end of the elastic hook 300 moves and opens, so that the opening of the locking groove 310 increases until the second rope 20 falls out of the locking groove 310. During this process, the force applied to the rope hook is evenly distributed, avoiding damage to the rope hook caused by partial excessive load on the rope hook, and extending the service life of the rope hook.

[0021] Furthermore, by providing a gripping handle 200 on the upper part of the hook body 100, a gripping portion is provided when the rope hook is connected to the rope. During the process of attaching the rope hook and the rope, first, the first rope 10 passes through the through hole 110. When hooking the second rope 20 to the elastic hook 300, force can be applied to the elastic hook 300 to open the elastic hook 300 while holding the gripping handle 200, and the elastic hook 300 is then hooked to the second rope 20, thereby reducing damage to the operator's fingers due to compression of the rope and the difficulty of hooking the rope hook and the rope, and thereby reducing the difficulty of connecting the rope hook and the rope.

[0022] Furthermore, the first rope 10 passes through the through-hole 110 and is fixed. When the second rope 20 receives a force in the front-rear direction and moves away from the hook body 100, the second rope 20 rotates the hook around the first rope 10. In this embodiment, by providing the limiting fins 120 on both sides of the hook body 100, when the hook is prone to rotation, the limiting fins 120 abut against the first rope 10, thereby restricting the relative rotation between the hook and the first rope 10, and preventing the first rope 10 from rotating around the first rope 10. Further, when the hook of this embodiment is positioned on a flat surface, the gripping handle 200 also abuts against the flat surface, further restricting the rotation of the rope hook. In this way, damage to the connection between the rope hook and the rope due to the rotation of the rope hook is avoided, and the stability of the rope hook when connecting the rope is improved.

[0023] In one embodiment, the gripping handle 200 is inclined toward the side of the hook body 100 where the elastic hook 300 is located, and on the surface of the hook body 100 facing away from the elastic hook 300, there is an inclined surface that is inclined toward the side closer to the elastic hook 300, and the surface smoothly transitions to the gripping handle 200. This can also be understood as promoting the deformation of the rope hook under an external tension, as the entire upper part of the rope hook is bent toward one side, while the lower part is bent toward the upper part of the rope hook. Further, the curved design of the overall structure of the rope hook also facilitates extending the line connecting the through-hole 110 and the locking groove 310 in the vertical direction.

[0024] In this embodiment, the inner diameter of the portion of the through-hole 110 adjacent to the gripping handle 200 is larger than the inner diameter of the portion of the through-hole 110 adjacent to the elastic hook 300. Therefore, when the rope hook connects the first rope 10 and the second rope 20, and one of the first rope 10 or the second rope 20 is tightened, the first rope 10 is positioned on the side of the through-hole 110 away from the elastic hook 300, abutting against the inner wall of the through-hole 110, preventing the first rope 10 from sliding toward the side of the through-hole 110 closer to the elastic hook 300. At the same time, the design of the through-hole 110 with various diameters limits the threads and fixing position of the first rope 10, reduces the difficulty of attaching the first rope 10, and achieves a reduction in the weight of the rope hook. Furthermore, the thickness of the portion of the hook body 100 between the gripping handle 200 and the elastic hook 300 gradually decreases in the direction toward the elastic hook 300, and the width of the portion of the hook body 100 between the gripping handle 200 and the elastic hook 300 gradually decreases in the direction toward the elastic hook 300. In this way, the strength of the connection portion between the first rope 10 and the hook body 100 is ensured, and the edge of the through hole 110 is not damaged by overload, while also providing the gripping handle 200 with a larger gripping area than the operator, reducing the difficulty for the operator when gripping the gripping handle 200. Moreover, this also promotes the elastic deformation of the elastic hook 300 when subjected to external force, making it easier to hook the second rope 20 onto the elastic hook 300.

[0025] In one embodiment, the thickness of the end portion of the elastic hook 300 is greater than the thickness of the connection portion between the elastic hook 300 and the hook body 100, and the width of the end portion of the elastic hook 300 is smaller than the width of the connection portion between the elastic hook 300 and the hook body 100. This prevents damage to the end portion of the elastic hook 300 due to overload, while reducing the difficulty in operating the elastic hook 300. Furthermore, in this embodiment, the end portion of the elastic hook 300 protrudes toward the interior of the locking groove 310, forming a limiting projection for regulating the position of the second rope 20. This limiting projection also constitutes a part of the locking groove 310, thereby reducing the opening size of the locking groove 310 in its natural state and preventing the second rope 20 from detaching from the locking groove 310. Preferably, the locking groove 310 has a teardrop shape, and the opening of the locking groove 310 is located at the top of the teardrop shape. Notably, in this embodiment, the end face of the elastic hook 300 is formed in a concave shape to constitute the operating part 320, and both side edges of the operating part 320 are arc-shaped. In this way, when hooking the second rope 20 onto the elastic hook 300, the operator can press the operating part 320. When a downward force is applied to the operating part 320, the operating part 320 rotates together with the elastic hook 300 away from the hook body 100, thereby increasing the opening width of the locking groove 310, making it possible to position the second rope 20 within the locking groove 310. In this structure, the concave design of the operating part 320 prevents slippage when the operator presses the elastic hook 300, thus reducing the difficulty of attaching the second rope 20.

[0026] In one embodiment, the hook body 100 is provided with a retraction hole 130 in the center that extends vertically and penetrates its front and back surfaces. The width of the upper part of the retraction hole 130 is greater than the width of the lower part of the retraction hole 130. This can be understood as forming a substantially inverted triangle. The design of the retraction hole 130 makes it easier for the operator to insert their fingers into the retraction hole 130 when gripping the hook, thereby making it easier for the operator to grasp the rope hook. Furthermore, the retraction hole 130 also functions as a weight-reducing hole for the rope hook to reduce the overall weight. In addition, in this embodiment, if the hook is made of plastic, the retraction hole 130 provided in the center of the hook body 100 allows for elastic deformation on both sides of the retraction hole 130 when a large force or a sudden strong tensile force is applied to the first and second ropes. This elastic deformation causes both sides of the retraction hole 130 to move toward the center of the retraction hole 130, thereby offsetting some of the force and preventing damage to the rope hook.

[0027] Preferably, in this embodiment, the outer contour of the gripping handle 200 has a smooth arc shape to prevent the operator from injuring their hand with sharp parts of the outer surface of the gripping handle 200 when the operator firmly grips the gripping handle 200.

[0028] The technical features of the embodiments described above can be combined in any suitable manner. For the sake of brevity, not all possible combinations of each technical feature in the embodiments described above are described in detail. However, as long as these combinations of technical features are not contradictory, all such combinations will be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of some embodiments of the present invention and should not be interpreted as limiting the scope of the utility model registration, nor should they be described in a more specific and detailed manner. Those skilled in the art should note that numerous modifications and improvements are possible without departing from the concept of the present invention, and all of these fall within the scope of the protection provided for the present invention. Therefore, the scope of the utility model registration protection for the present invention shall be determined by the attached claims for utility model registration.
