Usually one end of the rope hook is fixed to one rope segment, and the other end can be detachably assembled on another rope segment to connect the two rope segments; or the two ends of the rope hook can be detachably assembled on two rope segments to fix the rope segments, thereby solving the problem of insufficient length of a single rope segment, and by adjusting the length of the rope segment, it can achieve the tightening and compression of other objects. Technical issues

[0003] The hook is then attached to the other end of the rope and the hook is then attached to the other end of the rope, which in turn causes the hook to become loose and break. Technical Solutions

[0004] Based on this, it is necessary to provide a rope hook that is easy to install and grasp, has reliable connection and is not easy to break in order to address the above shortcomings.

[0005] A rope hook comprises a hook body, wherein the upper portion of the hook body is provided with a connecting hole extending in the horizontal direction and used for connecting a first rope, the upper portion of the hook body protrudes above the connecting hole and forms a gripping handle, and two opposite sides of the front side of the hook body are respectively provided with a limiting fin at a position corresponding to the upper portion of the connecting hole; the lower portion of the hook body is bent upward to form an elastic hook with a superior arc structure, and the inner side surface of the elastic hook and the hook body are enclosed to form a hanging groove for constraining a second rope; the line connecting the center of the connecting hole and the center of the hanging groove extends in the vertical direction.

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

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

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

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

[0010] In one embodiment, the hanging groove is a water drop-shaped structure, and the notch of the hanging groove is located at the top of the water drop-shaped structure.

[0011] In one embodiment, a position avoidance hole is provided in the middle of the hook body, which passes through the front and back sides and extends from top to bottom, and the width of the upper portion of the position avoidance hole is greater than the width of the lower portion of the position avoidance hole.

[0012] In one embodiment, a surface of the limiting fin adjacent to the through hole is provided with an arc surface adapted to the inner contour of the through hole.

[0013] In one embodiment, the outer contour of the gripping handle is a smooth arc-shaped structure, and the end surface of the elastic hook is concave to form a toggle portion.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may 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.

[0023] Referring to Figures 1 and 6 , the present invention discloses a rope hook that is easy to install and grasp, has a reliable connection, and is not prone to breaking. The rope hook can be used to connect and limit mesh ropes on the front or side of a backpack, and can also be used to connect and secure separate storage ropes. Specifically, the rope hook includes a hook body 100, a gripping handle 200 located at the upper portion of the hook body 100, and an elastic hook 300 located at the lower portion of the hook body 100. In this embodiment, the hook body 100, the gripping handle 200, and the elastic hook 300 are made of the same material. Preferably, the hook body 100, the gripping handle 200, and the elastic hook 300 are all made of 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 of a plastic material such as POM, nylon, PE, PET, PC, PVC, or PP. Furthermore, in this embodiment, the hook body 100, gripping handle 200, and elastic hook 300 are integrally formed. Depending on the processing material, the hook body 100, gripping handle 200, and 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 of a single material.

[0024] Further referring to Figures 1-6, in this embodiment, the upper portion of the hook body 100 is provided with a horizontally extending insertion hole 110 for receiving the first rope 10. The upper portion of the hook body 100 protrudes above the insertion hole 110 to form a gripping handle 200. Two opposing sides of the front of the hook body 100 are each provided with a limiting fin 120 at a position corresponding to the upper portion of the insertion hole 110. Preferably, the limiting fin 120 has an arcuate surface adjacent to the insertion hole 110 that conforms to the inner contour of the insertion hole 110, so that the first rope 10, after being tightened, contacts the arcuate surface of the limiting fin 120, preventing relative sliding between the two. The lower portion of the hook body 100 is bent upward to form an elastic hook 300 with a superior arc structure. The inner side of the elastic hook 300 and the hook body 100 enclose a hooking groove 310 for restraining the second rope 20. The line connecting the center of the through hole 110 and the center of the hooking groove 310 extends vertically. In other words, the hooking groove 310 is located directly below the through hole 110. Preferably, the center of the through hole 110, the center of the hooking groove 310, and the center of gravity of the rope hook are on the same straight line. It should be noted that, in this embodiment, the front side of the hook body 100 is the side facing the operator when the rope hook is placed in the main view, the back side of the hook body 100 is the side facing away from the operator when the rope hook is placed in the main view, and the side side of the hook body 100 is the side facing or facing away from the operator when the rope hook is placed in the side view; the horizontal direction refers to the width direction of the hook body 100, that is, the left and right direction in the main view; the front and back direction refers to the thickness direction of the hook body 100, that is, the left and right direction in the side view; the vertical direction refers to the height direction of the hook body 100, that is, the up and down direction in the main view.

[0025] The above-mentioned rope hook extends in the vertical direction by limiting the line connecting the center of the through-hole 110 and the center of the hanging 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, after the elastic hook 300 is pulled, the tension acting on the rope hook will be evenly distributed on the connection part between the elastic hook 300 and the hook body 100 and the hook body 100. As the force increases, the elastic hook 300 deforms, and the end of the elastic hook 300 moves and opens, so that the notch of the hanging groove 310 increases until the second rope 20 falls off from the hanging groove 310. In this process, the rope hook is subjected to uniform force, which avoids the problem of rope hook breakage caused by local overload on the rope hook and extends the service life of the rope hook.

[0026] 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 installation process of the rope hook and the rope, the first rope 10 is first passed through the connection hole 110. When the second rope 20 is to be hooked on the elastic hook 300, a force can be applied to the elastic hook 300 to open the elastic hook 300. At the same time, the gripping handle 200 is grasped and the elastic hook 300 is hooked on the second rope 20, thereby avoiding damage to the operator's fingers caused by the rope squeezing and difficulty in hooking the rope hook and the rope, thereby reducing the difficulty of connecting the rope hook and the rope.

[0027] Furthermore, when the first rope 10 is passed through the insertion hole 110 and secured, and the second rope 20 is subjected to a force in the fore-aft direction and away from the hook body 100, the second rope 20 will cause the hook to rotate about the first rope 10. In this embodiment, by providing limiting fins 120 on both sides of the hook body 100, when the hook tends to rotate, the limiting fins 120 abut against the first rope 10, thereby limiting relative rotation between the hook and the first rope 10 and preventing the first rope 10 from causing the hook to rotate about the first rope 10. Furthermore, when the hook of this embodiment is positioned on a flat surface, the gripping handle 200 will also abut against the surface, further limiting the hook's rotation. This prevents failure of the hook-rope connection due to hook rotation and improves the stability of the hook-rope connection.

[0028] 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 the surface of the hook body 100 facing away from the elastic hook 300 is an inclined surface that is inclined toward the side closer to the elastic hook 300 and smoothly transitions into the gripping handle 200. Alternatively, the upper portion of the entire rope hook is bent toward one side, while the lower portion is bent toward the upper portion of the rope hook, thereby facilitating deformation of the rope hook under external tension. Furthermore, the bent design of the overall rope hook structure also facilitates vertical extension of the line connecting the through-hole 110 and the hooking slot 310.

[0029] 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. Thus, when the rope hook connects the first rope 10 and the second rope 20 and one of the first rope 10 and the second rope 20 is tightened, the first rope 10 is located on the side of the through-hole 110 away from the elastic hook 300 and abuts against the inner wall of the through-hole 110, preventing the first rope 10 from sliding in the through-hole 110 toward the side close to the elastic hook 300. At the same time, the large and small diameter design of the through-hole 110 limits the threading and fixing position of the first rope 10, reduces the threading difficulty of the first rope 10, and achieves weight reduction 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 approaching 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 approaching the elastic hook 300. In this way, while ensuring the strength of the connection between the first rope 10 and the hook body 100 and preventing the edge of the through-hole 110 from being overloaded and broken, it also provides the operator with a gripping handle 200 with a larger gripping area, reducing the difficulty of the operator holding the gripping handle 200. In addition, it is also beneficial for the elastic hook 300 to produce elastic deformation when subjected to external force, so as to hang the second rope 20 on the elastic hook 300.

[0030] In one embodiment, the thickness of the end of the elastic hook 300 is greater than the thickness of the connection between the elastic hook 300 and the hook body 100, and the width of the end of the elastic hook 300 is less than the width of the connection between the elastic hook 300 and the hook body 100. This reduces the difficulty of shifting the elastic hook 300 while preventing the end of the elastic hook 300 from breaking due to overload. Furthermore, in this embodiment, the end of the elastic hook 300 protrudes toward the interior of the hooking groove 310, forming a limiting protrusion for determining the position of the second cord 20. This limiting protrusion also forms part of the hooking groove 310, thereby reducing the size of the notch of the hooking groove 310 in its natural state and preventing the second cord 20 from falling out of the hooking groove 310. Preferably, the hooking groove 310 has a teardrop-shaped structure, with the notch of the hooking groove 310 located at the top of the teardrop-shaped structure. It should be emphasized that in this embodiment, the end surface of the elastic hook 300 is recessed and forms a toggle portion 320, and the two side edges of the toggle portion 320 are arc surfaces. In this way, when the second rope 20 is hung on the elastic hook 300, the operator can press the toggle portion 320. After the toggle portion 320 is subjected to a downward force, it will deflect together with the elastic hook 300 in a direction away from the hook body 100, thereby increasing the slot width of the hanging groove 310 so that the second rope 20 can be placed in the hanging groove 310. In this structure, the recessed design of the toggle portion 320 can avoid slipping when the operator presses the elastic hook 300, thereby reducing the difficulty of installing the second rope 20.

[0031] In one embodiment, a central portion of the hook body 100 is provided with a relief hole 130 extending from top to bottom, extending through the front and back surfaces. The width of the upper portion of the relief hole 130 is greater than the width of the lower portion of the relief hole 130. This can also be understood as forming a substantially inverted triangular structure. The design of the relief hole 130 facilitates the operator's finger insertion into the relief hole 130 when grasping the hook, facilitating a secure grip. Furthermore, the relief hole 130 also serves as a weight-reducing hole for the hook, reducing its overall weight. Furthermore, in this embodiment, when the hook is made of plastic, the relief hole 130 provided in the central portion of the hook body 100 allows for elastic deformation on both sides of the relief hole 130 when the first and second ropes are subjected to significant forces or sudden, high tension. This elastic deformation causes the sides of the relief hole 130 to move toward the central portion of the relief hole 130, thereby offsetting some of the force and preventing the hook from breaking.

[0032] Preferably, in this embodiment, the outer contour of the gripping handle 200 is a smooth arc-shaped structure to prevent the operator's hand from being scratched by the sharp parts of the outer surface of the gripping handle 200 when the operator grips the gripping handle 200 tightly.

[0033] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
