Description

Technical Field

[0001] This utility model relates to the field of climbing equipment technology, and in particular to a lightweight parallel double hook. Background Technology

[0002] Currently, traditional climbing equipment generally suffers from problems such as heavy weight, insufficient structural strength, poor environmental adaptability, and difficult maintenance. Conventional metal hooks are not portable due to their heavy materials, and the stress-concentrated parts are prone to deformation and breakage. They are also susceptible to corrosion, especially in harsh environments such as the sea and desert, which affects safety and service life. Moreover, the traditional hook body is a fixed design, making it difficult to quickly replace parts after damage, which increases maintenance costs. Although some improvements have been made in the existing technology, such as the patent with patent number CN222391324 which discloses an inverted hook, the inverted double hook includes a hook handle, and multiple inverted single hooks are fixedly connected to the hook handle. The multiple inverted single hooks are staggered at a certain angle. When the inverted hook is supported on the surface of the support body, there will be at least two fulcrums between the inverted hook and the support body. Since the at least two fulcrums of the inverted single hook will restrict each other, the inverted hook itself can be prevented from tilting to the left or right. However, in actual use, when the hook is hung on the wall, it is easy for the center of gravity to shift, causing one side of the hook to be subjected to excessive force, which causes the hook to tilt and cause injury to the person climbing. Moreover, the contact surface between the hook and the wall is inclined, which cannot fit the wall well and has poor stability. Therefore, there is an urgent need for a lightweight parallel double hook with better stability. Utility Model Content

[0003] The purpose of this invention is to provide a lightweight parallel double hook to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A lightweight parallel double hook includes a connector, a hook shank, and hook bodies. The bottom end of the hook shank is movably connected to the top end of the connector. Two hook bodies are detachably connected to the top end of the hook shank. The two hook bodies are arranged in parallel, and the hook shank is inclined.

[0005] Furthermore, the hook handle includes a horizontal hook handle and a vertical hook handle. The top end of the vertical hook handle is integrally connected to the bottom end of the horizontal hook handle. The bottom end of the vertical hook handle is movably connected to the top end of the connector via a torsion spring. The hook body can be detachably connected to both ends of the horizontal hook handle. The vertical hook handle is inclined.

[0006] Furthermore, the transverse hook handle is provided with a placement hole, and a quick-release pin is placed in the placement hole.

[0007] Furthermore, a first weight-reducing groove is provided on both sides of the vertical hook handle.

[0008] Furthermore, a second weight-reducing groove is provided on both sides of the hook body.

[0009] Furthermore, the end of the hook body away from the lateral hook shank is detachably connected to a hook tip.

[0010] This utility model discloses the following technical effects: It discloses a lightweight parallel double hook with two hooks arranged in parallel. Compared to angled double hooks, this design provides better fit and more even force distribution when hooking onto supporting surfaces such as walls. When bearing loads, the parallel hooks can more stably distribute weight, reducing the risk of one hook tilting due to excessive force caused by a shift in the center of gravity. This greatly improves safety during climbing and provides more reliable support for climbers. Furthermore, the overall design features a detachable connection, facilitating component replacement and maintenance. Damaged components can be quickly replaced, reducing maintenance costs. The first and second weight-reducing grooves further reduce the weight of the double hooks and hook handles, meeting the requirements for lightweight design. Attached Figure Description

[0013] 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.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] The specific implementation method is as follows: like Figure 1 As shown, this utility model discloses a lightweight parallel double hook, including a connector 1, a hook shank, and two hook bodies 4. The hook shank includes a horizontal hook shank 3 and a vertical hook shank 2. The top end of the vertical hook shank 2 is integrally connected to the bottom end of the horizontal hook shank 3. A U-shaped groove is formed at the top end of the connector 1, and the bottom end of the vertical hook shank 2 extends into the U-shaped groove. The vertical hook shank 2 is located at the middle position of a torsion spring 5. A pin passes through the vertical hook shank 2, the torsion spring 5, and the connector 1. The two ends of the torsion spring 5 are respectively engaged with the two sides of the connector 1 to realize the connection between the hook shank and the horizontal hook body 4. The connector 1 is movable, and the pin can be pulled out for easy disassembly. Both ends of the horizontal hook handle 3 are detachably connected to the bottom of the hook body 4 by two internal hexagonal flower-shaped pan head screws 7. The two hook bodies 4 are arranged in parallel. The horizontal hook handle 3 is provided with a placement hole 9, and a quick-release pin 6 is placed in the placement hole 9. The vertical hook handle 2 is provided with a first weight-reducing groove 10 on both sides, and the hook body 4 is provided with a second weight-reducing groove 11 on both sides. The end of the hook body 4 away from the horizontal hook handle 3 is detachably connected to the hook tip 12 by an elastic cylindrical pin 8.

[0016] In this embodiment, both the hook body 4 and the connector 1 are made of titanium alloy, while the horizontal hook shank 3 and the vertical hook shank 2 are made of aerospace-grade aluminum alloy. This ensures that the lightweight parallel double hook has excellent load-bearing and corrosion resistance while being lightweight. The hook body 4 and the horizontal hook shank 3 are connected with high strength and reliability through M6 flower-shaped pan head bolts, which significantly improves the assembly and disassembly efficiency while ensuring safety. Through changes in materials and structure, the safety, durability, and ease of operation of the product are comprehensively improved.

[0017] In this embodiment, the vertical hook handle 2 is inclined, and the vertical hook handle 2 has a forward tilt angle of 5° to 20° relative to the vertical center line of the connector 1, preferably 15°. When the hook body 4 is hung on the wall or railing, the top of the vertical hook handle 2 and the horizontal hook handle 3 are closer to the wall or railing. This forward tilt design makes the force direction of the hook body consistent with the force direction of the ladder, so that the lever arm is shorter, the torque is smaller, and the overall stability is more complete.

[0018] In this embodiment, the corners of the hook body 4 are rounded, and the side of the hook body 4 closest to the wall or railing is thickened to avoid stress concentration, strengthen the stress point, and improve stability.

[0019] The first weight-reducing groove (10) and the second weight-reducing groove (11) are elongated oval grooves. They remove redundant materials to the maximum extent while ensuring structural strength, thereby achieving lightweighting.

[0020] This utility model provides a storage position for quick-release pins 6 on the horizontal hook handle 3, which prevents the quick-release pins 6 from being carelessly placed and lost after the lightweight parallel double hooks are disassembled from the climbing ladder pole 13.

[0021] The two hooks 4 are arranged in parallel. When the hooks 4 are hooked to the wall or railing, compared with the angled double hooks, the contact surface between the hooks 4 and the wall or railing is larger and the force is more even. When the double hooks are hooked to the wall or railing, the two hook tips 12 can simultaneously fit into the support surface, forming two-point symmetrical force. Even if the climber's center of gravity shifts, the load can be distributed to the two hooks 4, resulting in high stability.

[0022] The lightweight parallel double hook of this invention is installed on a climbing ladder. The bottom of the connector 1 of this invention has an opening for connecting the climbing ladder. The top of the climbing ladder rod and the lightweight parallel double hook are connected by a quick-release pin 6 with a diameter of 10mm passing through the opening of the connector 1 and the rod, which can quickly realize the connection and separation of the two and improve efficiency.

[0023] This utility model relates to a high-strength, lightweight parallel double hook, which optimizes the load-bearing support structure and significantly reduces the overall weight while ensuring load-bearing capacity and stability through reasonable layout and material selection.
