[0002] With the rapid development of the aviation industry, airborne rescue equipment plays an increasingly important role in ensuring flight safety and improving rescue efficiency. Titanium alloy, as a lightweight and high-strength metal material, has been widely used in the aviation field.

[0003] Due to the characteristics of titanium alloy itself, it can also be made into rescue hooks, but the existing rescue hooks still have some shortcomings when used:

[0004] Existing rescue hooks are generally made of an integral body or are composed of various parts. The structure of the rescue hook is relatively fixed and difficult to fold and store. It is not only inconvenient to carry but also takes up a large space. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the foldable hook is difficult to fold and store, is not only inconvenient to carry, but also occupies a large space, and proposes a titanium alloy airborne rescue folding hook.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A titanium alloy airborne rescue folding hook comprises a storage rack, one side of which is fixedly connected to a fixing plate, the fixing plate being provided with four fixing holes, and the fixing plate being fixed by bolts passing through the four fixing holes, a rotating shaft being rotatably connected within the storage rack, a hook body being provided below the rotating shaft, a clamping plate being provided below the rotating shaft, the clamping plate and the hook body being in contact with each other, and both the hook body and the clamping plate being stored in the storage rack;

[0008] It also includes a flip component, which is located at both ends of the rotating shaft and in the storage rack. The flipping of the rotating shaft can be limited by the flipping component.

[0009] In a possible design, the flip assembly includes a second vertical groove provided on the inner walls on both sides of the storage rack, circular grooves are provided on the inner walls on both sides of the storage rack, square card slots are provided on the inner walls on both sides of the storage rack, and the two ends of the second vertical groove are respectively connected to the circular groove and the square card slot, and the two ends of the rotating shaft are fixedly connected with square card blocks, and the square card blocks can rotate and cooperate in the circular groove and the second vertical groove, and can be stuck in the square card slot.

[0010] In a possible design, a first vertical slot is provided on one side of the storage rack, a through slot is provided on the bottom of the storage rack, and the first vertical slot and the through slot are connected.

[0011] In one possible design, a limiting groove is provided in the rotating shaft, a through groove connected to the limiting groove is provided in the rotating shaft, a connecting plate is rotatably arranged in the limiting groove, a first connecting column is fixedly connected to the bottom of the connecting plate, and the bottom end of the first connecting column passes through the through groove.

[0012] In a possible design, the bottom of the first connecting column is fixedly connected to the second connecting column, and the first connecting column can move in the first vertical groove and the through groove.

[0013] In a possible design, a connecting shaft is rotated and passed through the second connecting column, and one end of the hook is fixedly sleeved on the outer wall of the connecting shaft, and the other end of the connecting shaft is fixedly sleeved with a connecting ear, and the clamping plate is connected to the connecting ear through the rotating shaft, and a torsion spring is fixed between the clamping plate and the connecting ear, and the torsion spring is sleeved on the rotating shaft.

[0014] In the present application, the folding hook is made of titanium alloy, and four fixing holes are provided on the fixing plate, which can be fixed by bolts passing through the fixing holes. This design allows the user to fix the rescue folding hook on different positions or carriers as needed, thereby increasing its adaptability and flexibility. The main body is connected to a rotating shaft in a rotating manner in the storage rack, and a hook body and a card plate are provided below the rotating shaft. The two realize locking and unlocking of the folding hook by interference. When the rescue folding hook needs to be unfolded, the rotating shaft is rotated to the required angle, and the card plate is separated from the hook body through operation to hook it, and then the card plate and the hook body are matched to achieve sealing. When folding, the hooked object is removed, and the card plate and the hook body are re-interfered through operation, and then the rotating shaft is rotated to the storage position to be stored in the storage rack. The flip assembly includes a second vertical slot, a circular slot and a square card slot, as well as square card blocks at both ends of the rotating shaft. The square card block rotates in the circular slot and the second vertical slot. When a specific angle is reached, a card is formed in the square card slot to limit further flipping of the rotating shaft. In this way, the folding hook is ensured to be unfolded. When opened or folded, it can stay at a preset angle, increasing the stability of operation. A limiting groove and a through groove are provided in the rotating shaft. The first connecting column and the connecting plate are respectively passed through the through groove and the limiting groove. The bottom of the first connecting column is connected to the second connecting column. A connecting shaft is rotated and passed through the second connecting column, so that the hook body can be flexibly rotated, which is more convenient for hooking. This internal design allows the hook body and the card plate to be controlled to rotate and flip by operating the first connecting column and the second connecting column, thereby realizing the flexible use of the folding hook. At the same time, the fixing plate can also be connected to the connecting rod, which can be connected to the threaded hole of the fixing plate through the screw thread at one end of the connecting rod. The four hook claws can rotate around the limiting piece in the limiting frame. When the hook claw is unfolded, the inner wall of one side of the limiting frame can form a conflict to limit the flipping angle of the limiting frame. At the same time, the limiting piece is composed of a bolt and a nut. The limiting frame can be clamped by rotating the nut and the bolt, so that the two sides of the hook claw are clamped to a certain extent through the limiting frame. At this time, one end of the hook claw can hook the object, and the hook body is connected to the rescue end, which is more flexible to use.

[0015] Beneficial effects:

[0016] In the utility model, the titanium alloy airborne rescue folding hook is made of titanium alloy material to ensure the lightness and high strength of the rescue folding hook. At the same time, the folding design greatly reduces its volume, making it easy to carry and store.

[0017] In the utility model, the titanium alloy airborne rescue folding hook has a folding and storage design, which enables the rescue folding hook to adapt to various spaces and storage conditions, thereby improving its applicability;

[0018] In the utility model, the entire structure is light in texture and high in strength, and at the same time has the effect of storage, is easy to carry, occupies little space, and has multi-angle rotation and flexible flipping effects, which can be used more flexibly and increase the convenience of use.
