AI Technical Summary
Traditional hooks cannot be folded, take up a lot of space, and lack an effective positioning structure, making them prone to accidental unfolding when folded.
A folding hook was designed, which achieves 90° folding of the hook body by setting an elastic positioning pin and positioning groove structure between the hook body and the connecting part, and ensures accurate positioning through tactile feedback.
It achieves stable positioning of the hook in different states, reduces space occupation, and is easy to operate. Users can confirm the locking status by feel.

Abstract
Description
Technical Field
[0001] This utility model relates to a hook, and more particularly to a folding hook. Background Technology
[0002] Traditional hooks typically have a fixed structure, cannot be folded, take up a lot of space, and are inconvenient for storage and transportation. To solve this problem, foldable hooks have emerged in existing technology, which achieve the folding function through hinged or rotating structures, thereby reducing the space occupied when not in use. However, existing foldable hooks often lack an effective positioning structure when folded, making them prone to accidental unfolding when folded. Utility Model Content
[0003] In view of the shortcomings of existing technology, this utility model provides a folding hook.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a folding hook, including a base and a hook body. The base has a semi-circular connecting part, and one end of the hook body has a semi-circular first groove. The hook body has a stop block along the radius of the first groove. The hook body is sleeved on the connecting part through the first groove. The semi-circular connecting part has a semi-circular second groove at its center. The end of the stop block has an arc-shaped third groove concentric with the second groove, and the radius of the third groove is equal to that of the second groove. A rotating shaft is provided in the second groove. Two first positioning grooves are provided on the arc surface of the connecting part, and one second positioning groove is provided on the arc surface of the first groove. An elastic positioning pin is provided in the second positioning groove. The elastic positioning pin is engaged in one of the first positioning grooves to limit the rotation of the hook body.
[0005] The first positioning groove and the second positioning groove are arc-shaped, and the first positioning groove and the second positioning groove are joined together to form a circular hole. The elastic positioning pin is cylindrical.
[0006] The curvature of the second positioning groove is greater than half a circle.
[0007] The angle between the two first positioning grooves and the center of the connecting part is 90°.
[0008] The third groove has a radius of one-quarter circle.
[0009] The beneficial effects of this utility model are as follows: Through structural design, the elastic positioning pin engages with the first positioning groove in both the open and folded states of the hook, limiting the rotation of the hook body. The change in damping sensation when the elastic positioning pin engages with the first positioning groove provides tactile feedback to the user, indicating whether the hook is properly engaged. This utility model also features a simple structure, convenient processing, and easy assembly, making it highly practical. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the hook structure of this utility model;
[0012] Figure 3 This is a schematic diagram of the folded state of this utility model. Detailed Implementation
[0013] like Figures 1-3 As shown, a folding hook includes a base 1 and a hook body 2. The base 1 has a semi-circular connecting part 11. One end of the hook body 2 has a semi-circular first groove 21. A stop block 22 is provided along the radius of the first groove 21 on the hook body 2. The hook body 2 is sleeved on the connecting part 11 through the first groove 21. The semi-circular connecting part 11 has a semi-circular second groove 12 at its center. The end of the stop block 22 has an arc-shaped third groove 23 concentric with the second groove 12, and the radius of the third groove 23 is equal to that of the second groove 12. A rotating shaft 3 is provided in the second groove 12. Two first positioning grooves 13 are provided on the arc surface of the connecting part 11, and one second positioning groove 24 is provided on the arc surface of the first groove 21. An elastic positioning pin 4 is provided in the second positioning groove 24. The elastic positioning pin 4 is engaged with one of the first positioning grooves 13 to limit the rotation of the hook body 2. In this embodiment, the base 1 has two connecting parts 11 to connect two hook bodies 2. Figure 1 As shown, with the hook body 2 in the open state, the elastic positioning pin 4 engages with the first positioning groove 13 on the left, and the left end of the hook body 2 abuts against the base 1, as shown. Figure 3 As shown, the upper hook 2 is in a folded state. When the hook 2 rotates upward, the elastic positioning pin 4 is engaged in the first positioning groove 13 on the right.
[0014] The first positioning groove 13 and the second positioning groove 24 are arc-shaped, and together they form a circular hole. The elastic positioning pin 4 is cylindrical. The curvature of the second positioning groove 24 is greater than half a circle. The included angle between the two first positioning grooves 13 and the center of the connecting part 11 is 90°. Figure 3 The center angle A is 90°. Through the above design, the opening and folding angles of hook 2 can change by 90°, realizing the change of the horizontal and vertical states of hook 2. Of course, the included angle can also be adjusted as needed to achieve different folding angles.
[0015] The third groove 23 has a radius of one-quarter circle. This allows the end of the stop block 22 to abut against the top of the connecting part 11 when the hook body 2 is rotated 90° and folded, thus achieving double limiting.
[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Simple modifications and substitutions made by those skilled in the art without departing from the spirit and scope of this utility model are within its protection scope.
