Referring to fig. 1 and 6, the utility model discloses a rope hook which is favorable for installation and holding, reliable in connection and difficult to break, and the rope hook can be used for limiting connection of a net-shaped structure rope on the front or side of a backpack, and can also be used for connecting and fixing a storage rope which is used independently. Specifically, the rope hook includes a hook body 100, a grip handle 200 located at an upper portion of the hook body 100, and an elastic hook 300 located at a lower portion of the hook body 100, in this embodiment, the hook body 100, the grip handle 200, and the elastic hook 300 are made of the same material, preferably, the hook body 100, the grip handle 200, and the elastic hook 300 are made of plastic or metal materials capable of being elastically deformed, for example, the hook body 100, the grip handle 200, and the elastic hook 300 are made of plastic materials such as POM, nylon (Nylon), PE, PET, PC, PVC, or PP. In the present embodiment, the hook body 100, the grip handle 200, and the elastic hook 300 are integrally molded, and the hook body 100, the grip handle 200, and the elastic hook 300 may be integrally molded by injection molding or the like, depending on the processing material. In other words, in this embodiment, the rope hook is a separate integral part made of a single material.

Referring to fig. 1-6, in this embodiment, a through hole 110 extending along a horizontal direction for passing through the first rope 10 is formed in an upper portion of the hook body 100, the upper portion of the hook body 100 protrudes above the through hole 110 and forms a gripping handle 200, and a limiting fin 120 is disposed at each of two opposite sides of a front surface of the hook body 100 corresponding to the upper portion of the through hole 110. Preferably, the surface of the limiting fin 120 adjacent to the through hole 110 is provided with an arc surface adapted to the inner contour of the through hole 110, so that the first rope 10 is in limiting abutting connection with the arc surface of the limiting fin 120 after being tensioned, and the first rope and the limiting fin are prevented from sliding relatively. The lower part of the hook body 100 is bent upwards to form an elastic hook 300 in a major arc structure, and the inner side surface of the elastic hook 300 is enclosed with the hook body 100 to form a hanging 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 in the vertical direction, in other words, the hooking groove 310 is located right under the through-hole 110. Preferably, the center of the penetration hole 110, the center of the hooking recess 310, and the center of gravity of the rope hook are positioned on the same straight line. In this embodiment, the front surface of the hook body 100 is a surface facing the operator when the rope hook is placed in the front view state, the back surface of the hook body 100 is a surface facing away from the operator when the rope hook is placed in the front view state, and the side surface of the hook body 100 is a surface facing or facing away from the operator when the rope hook is placed in the side view state; the horizontal direction refers to the width direction of the hook body 100, i.e., the left-right direction in the front view; the front-rear direction refers to the thickness direction of the hook body 100, i.e., the left-right direction in a side view; the vertical direction refers to the height direction of the hook body 100, i.e., the up-down direction in the front view.

The rope hook extends along the vertical direction through the connecting line between the center of the through hole 110 and the center of the hooking groove 310, under the condition that the first rope 10 is fixed and the tensile force applied to the second rope 20 and facing away from the direction of the first rope 10 is increased, after the elastic hook 300 is pulled, the tensile force acting on the rope hook is uniformly distributed on the connecting part of the elastic hook 300 and the hook body 100, along with the increase of acting force, the elastic hook 300 deforms, the tail end of the elastic hook 300 moves and expands, the notch of the hooking groove 310 is increased until the second rope 20 falls off from the inside of the hooking groove 310, and in the process, the stress of the rope hook is uniform, the problem of rope hook breakage caused by local overload on the rope hook is avoided, and the service life of the rope hook is prolonged.

Furthermore, by providing the grip handle 200 at the upper portion of the hook body 100, a grip portion is provided when the rope hook is connected with the rope, in the installation process of the rope hook and the rope, the first rope 10 is firstly passed through the through hole 110, when the second rope 20 is to be hooked on the elastic hook 300, an acting force can be applied to the elastic hook 300, so that the elastic hook 300 is opened, the grip handle 200 is gripped at the same time, the elastic hook 300 is hooked on the second rope 20, the damage caused by the rope extrusion of the operator finger and the problem of difficult hooking of the rope hook and the rope are avoided, and the connection difficulty of the rope hook and the rope is reduced.

In addition, when the first rope 10 passes through the through hole 110 and is fixed, and the second rope 20 receives a force in the front-rear direction and deviated from the hook body 100, the second rope 20 drives the rope hook to rotate around the first rope 10, and in this embodiment, by providing the limiting fins 120 on both sides of the hook body 100, when the rope hook generates a rotation trend, the limiting fins 120 abut against the first rope 10, that is, the relative rotation between the rope hook and the first rope 10 is limited, so that the first rope 10 is prevented from driving the rope hook to rotate around the first rope 10. In addition, when the rope hook of the embodiment is arranged on a plane, the gripping handle 200 is also abutted against the plane, so that the rotation of the rope hook is further limited, the problem that the rope hook is connected with the rope to be invalid due to the rotation of the rope hook can be avoided, and the stability of the rope hook connected with the rope is improved.

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 inclined toward the side close to the elastic hook 300 and smoothly transiting with the gripping handle 200. It can be understood that the upper portion of the whole rope hook is bent to one side, and the lower portion of the whole rope hook is bent to a direction close to the upper portion of the rope hook, so that conditions are provided for deformation of the rope hook under the action of external tension, and meanwhile, the bending design of the whole rope hook structure also provides conditions for the connection line of the through hole 110 and the hooking groove 310 to extend along the vertical direction.

In this embodiment, the inner diameter of the portion of the through-connection hole 110 adjacent to the grip handle 200 is larger than the inner diameter of the portion of the through-connection hole 110 adjacent to the elastic hook 300, so when the rope hook connects the first rope 10 and the second rope 20 and one rope of the first rope 10 and the second rope 20 is tensioned, the first rope 10 is located at one side of the through-connection hole 110 far away from the elastic hook 300 and abuts against the inner wall of the through-connection hole 110, the first rope 10 is prevented from sliding in the through-connection hole 110 to one side close to the elastic hook 300, and meanwhile, the size and diameter design of the through-connection hole 110 defines the through-connection fixing portion of the first rope 10, the through-connection difficulty of the first rope 10 is reduced, and the weight reduction of the rope hook is realized. Further, the thickness of the portion of the hook body 100 between the grip handle 200 and the elastic hook 300 is gradually reduced along the direction approaching the elastic hook 300, and the width of the portion of the hook body 100 between the grip handle 200 and the elastic hook 300 is gradually reduced along the direction approaching the elastic hook 300, so that the strength of the connection portion of the first rope 10 and the hook body 100 is ensured, the edge overload fracture of the through hole 110 is prevented, the grip handle 200 with a larger grip area is provided for an operator, the difficulty of the operator in gripping the grip handle 200 is reduced, and in addition, the elastic hook 300 is also facilitated to generate elastic deformation when being subjected to external force, so that the second rope 20 is hung on the elastic hook 300.

In an embodiment, the thickness of the end 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 of the elastic hook 300 is smaller than the width of the connection portion between the elastic hook 300 and the hook body 100, so that the difficulty in pulling the elastic hook 300 is reduced, and meanwhile, overload breakage of the end of the elastic hook 300 can be avoided. Further, in the present embodiment, the end of the elastic hook 300 protrudes toward the inside of the hooking groove 310 to form a limiting protrusion for limiting the position of the second rope 20, and the limiting protrusion also forms a part of the hooking groove 310, so as to reduce the size of the notch of the hooking groove 310 in a natural state and prevent the second rope 20 from falling off from the hooking groove 310. Preferably, the hooking groove 310 has a drop-shaped structure, and the notch of the hooking groove 310 is located at the top of the drop-shaped structure. It should be emphasized that in this embodiment, the end surface of the elastic hook 300 is recessed and forms the poking part 320, and the edges of both sides of the poking part 320 are arc surfaces, so when the second rope 20 is hooked on the elastic hook 300, an operator can press the poking part 320, after the poking part 320 receives downward force, the poking part is deflected along with the elastic hook 300 in a direction away from the hook body 100, so that the width of the notch of the hooking groove 310 is increased, so that the second rope 20 is placed in the hooking groove 310.

In an embodiment, the middle portion of the hook body 100 is provided with a avoidance hole 130 extending from top to bottom through the front and back surfaces thereof, and the width of the upper portion of the avoidance hole 130 is greater than the width of the lower portion of the avoidance hole 130, which can be understood that the avoidance hole 130 has an approximately inverted triangle structure. The design of the avoidance hole 130 is beneficial to the operator to insert the fingers into the avoidance hole 130 when the operator grasps the rope hook, so that the operator can grasp the rope hook conveniently, and on the other hand, the avoidance hole 130 can also be used as a lightening hole of the rope hook so as to reduce the overall weight of the rope hook. In addition, in this embodiment, when the rope hook is made of plastic material, by forming the avoidance hole 130 in the middle of the hook body 100, if the first rope and the second rope are stressed more or are subjected to a transient and larger tensile force, the two sides of the avoidance hole 130 will elastically deform, so that the two sides of the avoidance hole 130 move in a direction close to the middle of the avoidance hole 130, and thus, part of the force is offset, so as to avoid the rope hook from breaking.

Preferably, in this embodiment, the outer contour of the grip handle 200 has a smooth arc structure, so as to avoid the sharp portion on the outer surface of the grip handle 200 from scratching the hand of the operator when the operator grips the grip handle 200.
