Abstract
Description
Technical Field
[0001] This utility model relates to the field of hook and loop technology, and in particular to a one-handed quick-opening hook and loop. Background Technology
[0002] In the field of outdoor gear, backpacks, as essential carrying tools, directly impact user experience through the ease of use of their hook and loop fasteners. Currently, the hook and loop structures used in most backpacks on the market have significant flaws. This design often requires the user to use both hands simultaneously: one hand to hold the loop while the other applies force to pry open the hook and loop. This method is not only time-consuming and laborious, but also extremely inconvenient for hikers carrying heavy gear, needing to grip trekking poles with one hand, or in emergency situations. It severely impacts outdoor efficiency and may even delay crucial safety precautions, failing to meet users' needs for convenient and efficient backpack use. Utility Model Content

[0021] To achieve the above objectives and effects, the technical means and structures adopted by the utility model are described in detail in combination with the drawings for the preferred embodiments of the utility model to illustrate their features and functions.
[0022] As shown in the Figures 1-4 drawing, a one-handed quick-opening hook is provided in the utility model, including:
[0023] A main body 1, the main body 1 is in a hook shape and is provided with an activity groove 6;
[0024] Pull rod 2 is set in the movable groove 6 and is rotatably connected to the movable groove 6. The outline of pull rod 2 is adapted to the outline of the main body 1, and the bottom of pull rod 2 extends out of the movable groove 6.
[0025] Baffle 3 is mounted on pull rod 2 and rotatably connected to pull rod 2;
[0026] The first spring 4 is disposed in the movable groove 6 and is used to reset the pull rod 2.
[0027] The second spring 5 is mounted on the pull rod 2 and is used to reset the baffle 3.
[0028] Specifically, the movable groove 6 is provided with a first rotating shaft 7 and a second rotating shaft 8, which are detachably connected to the movable groove 6. The pull rod 2 is provided with a first through hole, and the pull rod 2 is sleeved on the first rotating shaft 7 through the first through hole. The first spring 4 is a torsion spring, which is sleeved on the second rotating shaft 8, and both ends of the first spring 4 are connected to the pull rod 2.
[0029] Specifically, the pull rod 2 is provided with a locking groove, and a third rotating shaft 9 is provided in the locking groove. The baffle 3 is provided with a second through hole, and the baffle 3 is sleeved on the third rotating shaft 9 through the second through hole. The baffle 3 is provided with a reset groove. The second spring 5 is a torsion spring, and the second spring 5 is sleeved on the third rotating shaft 9 and located in the reset groove.
[0030] When the device is in the closed state, the end of the baffle 3 away from the pull rod abuts against the main body 1, thereby forming a closed space with the hook-shaped main body 1, thus limiting the lifting ring and rope. At this time, the baffle 3 itself is restricted by the main body 1 and cannot rotate away from the outside of the main body 1, but can only rotate towards the main body 1, so that the user can quickly put the lifting ring into the closed space of the main body 1. At the same time, after the ring is put in, the baffle 3 will quickly return to its original position under the action of the second spring 5, thereby preventing the lifting ring from coming out of the main body 1.
[0031] When the user needs to remove the lifting ring, the user can pull the lever 2, causing the lever 2 and the baffle 3 to rotate relative to the main body 1, so that the baffle 3 no longer forms a closed space with the main body 1, and the device is in the open state. At this time, the user can easily remove the lifting ring. After the lifting ring is removed, the lever 2 will return to its original position under the action of the first spring 4, waiting for the user's next use.
[0032] When using this device, no two-handed operation is required. The user can open and automatically close the device with only one hand operation, which is convenient and fast in use, effectively reducing the operation difficulty, having good adaptability to users of different ages and strength conditions, and significantly optimizing the user experience. While ensuring safety, it also provides a more convenient and efficient equipment solution for activities such as outdoor adventures.
[0033] In this embodiment, a buckle 10 is provided at the bottom of the main body 1, and the buckle 10 is in the shape of a Chinese character "ri". The user can pass a webbing through the buckle 10 in the shape of a Chinese character "ri", and the other end of the webbing is fixed on equipment such as a bag or a safety belt, so that the distance of the device can be adjusted by adjusting the threading length of the webbing and the buckle 10.
[0034] In this embodiment, a handle 11 is provided at the second end of the pull rod 2 to facilitate the operation of the user.
[0035] The above is only a preferred embodiment of the present utility model, not all embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all belong to the protection scope of the present utility model.
