Description
Technical Field
[0001] This utility model relates to the field of shackle technology, and in particular to a high-strength shackle that can be quickly detached. Background Technology
[0002] The quick-release high-strength shackle is a connecting component with high strength and load-bearing capacity, and can achieve quick connection and separation. It is mainly used in lifting, hoisting, and traction operations. It can quickly assemble or disassemble with rigging, connectors, etc. through convenient operation. While ensuring connection strength and safety, it greatly improves work efficiency and is suitable for industrial scenarios that require frequent connection operations.
[0003] In the existing C-type quick shackle, during use, when mechanical equipment vibrates or during lifting operations, the connecting parts are prone to move on the side walls of their dovetail blocks and shackle bodies, causing continuous friction between the parts and their bodies, resulting in significant wear and easily affecting the service life of the parts and their bodies.
[0004] An existing patent (publication number: CN221343543U) discloses a high-strength C-type quick-release buckle, relating to the field of buckle technology. Limiting discs are fixedly connected to both ends of the buckle body. A double U-shaped clamp is placed on the outer surface of the buckle body. Two arc-shaped notches are opened on the left side of the double U-shaped clamp. The double U-shaped clamp is inserted into the buckle body via a plug rod and a butterfly block. Two first arc-shaped rods are fixedly connected between the inner walls of the buckle body. First ball bearings are rotatably connected to the outer surfaces of the two first arc-shaped rods. A second arc-shaped rod is fixedly connected to the inner side of the wear-resistant groove of the butterfly block. Rotatable second ball bearings are spaced apart on the second arc-shaped rod. This high-strength C-type quick-release buckle enables rapid installation of the butterfly block, effectively improving user convenience. By setting the first and second ball bearings, the ball bearings can roll when the accessory moves on the surface of the butterfly block and the buckle body, effectively reducing the wear intensity between the whole and external accessories and improving service life.
[0005] To address the aforementioned issues, existing patents offer solutions. However, the installation and disassembly of existing high-strength shackles are often cumbersome, and once secured, they are difficult to unlock quickly, typically requiring specialized tools. This not only increases the number of steps but also reduces installation and disassembly efficiency. They are not well-suited for scenarios requiring frequent replacement or adjustment and are inconvenient for users.
[0006] Therefore, a method for quickly detaching high-strength shackles is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide a high-strength shackle that can be quickly detached, which can solve the problems that existing high-strength shackles are often cumbersome to install and disassemble, and difficult to quickly release the locked state after fixing. They usually require special tools to operate, which not only increases the number of operation steps, but also reduces the efficiency of loading and unloading. They are not suitable for scenarios that require frequent replacement or adjustment, and are inconvenient for users.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-strength shackle that can be quickly detached, comprising a shackle structure, a fixing mechanism movably connected to the inner wall of the shackle structure, a positioning component fixedly connected to the inner wall of the shackle structure, the surface of the positioning component engaging with the inner wall of the fixing mechanism, a limiting block movably connected to the inner wall of the shackle structure, the surface of the limiting block engaging with the inner wall of the fixing mechanism, the fixing mechanism including a positioning rod, the inner wall of the positioning rod engaging with the positioning component, the inner wall of the positioning rod engaging with the surface of the limiting block, a positioning plate fixedly connected to the rear side of the positioning rod, and a torsion plate fixedly connected to the rear side of the positioning plate.
[0009] Preferably, the positioning component includes a connecting block and a limiting plate. The connecting block is fixedly connected to the shackle structure on the side closest to the shackle structure, and the limiting plate is fixedly connected to the connecting block on the side closest to the connecting block.
[0010] Preferably, the surface of the connecting block is movably connected to the inner wall of the positioning rod, and the surface of the limiting plate is engaged with the inner wall of the positioning rod.
[0011] Preferably, the inner wall of the positioning rod is provided with a movable groove for use with the connecting block, and the inner wall of the positioning rod is provided with a limiting groove for use with the limiting block.
[0012] Preferably, a spring telescopic assembly is fixedly connected to the bottom of the limiting block, and the bottom of the spring telescopic assembly is fixedly connected to the inner wall of the positioning rod.
[0013] Preferably, a pull block is fixedly connected to the front side of the limiting block, and the surface of the pull block is movably connected to the inner wall of the shackle structure.

[0015] Preferably, a metal block is fixedly connected to the inner wall of the shackle structure, and a magnetic block is fixedly connected to the inner wall of the reinforcing plate, with the rear side of the magnetic block being magnetically connected to the front side of the metal block.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This application sets up a fixing mechanism. When in use, the fixing mechanism is inserted into the inner wall of the shackle structure. Then, the positioning rod will be synchronously engaged with the positioning component. By rotating the torsion plate, the positioning plate and the positioning rod will be rotated, so that the positioning component and the positioning rod can be precisely engaged to complete the initial positioning.

The positioning rod and the positioning plate are simultaneously disengaged from the inner wall of the shackle structure. The entire operation is completed by the linkage structure of the fixing mechanism, without the need for additional tools, which greatly shortens the disassembly time, simplifies the operation procedures in frequent loading and unloading scenarios, and improves work efficiency and convenience.

Detailed Implementation
[0027] 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.
[0028] Please see Figure 1-7 The present invention provides the following technical solution:
[0029] A high-strength shackle that can be quickly detached includes a shackle structure 1. A fixing mechanism 2 is movably connected to the inner wall of the shackle structure 1. A positioning component 3 is fixedly connected to the inner wall of the shackle structure 1. The surface of the positioning component 3 engages with the inner wall of the fixing mechanism 2. A limiting block 4 is movably connected to the inner wall of the shackle structure 1. The surface of the limiting block 4 engages with the inner wall of the fixing mechanism 2. The fixing mechanism 2 includes a positioning rod 201. The inner wall of the positioning rod 201 engages with the positioning component 3. The inner wall of the positioning rod 201 engages with the surface of the limiting block 4. A positioning plate 202 is fixedly connected to the rear side of the positioning rod 201. A torsion plate 203 is fixedly connected to the rear side of the positioning plate 202.
[0030] In this embodiment: By setting a fixing mechanism 2, when in use, the fixing mechanism 2 is inserted into the inner wall of the shackle structure 1. Then, the positioning rod 201 will be synchronously engaged with the positioning component 3. By rotating the torsion plate 203, the positioning plate 202 and the positioning rod 201 will be rotated, so that the positioning component 3 and the positioning rod 201 are precisely engaged to complete the initial positioning. After the positioning rod 201 enters the preset fixed position, the limiting block 4 automatically engages with the inner wall of the positioning rod 201 to lock the position. With the help of the structural adaptation of the positioning rod 201 and the limiting effect of the positioning plate 202, the connection between the fixing mechanism 2 and the shackle structure 1 is realized. Rapid installation ensures the accuracy and structural stability of the assembly process. By setting a limit block 4, during subsequent disassembly, the locking state of the positioning rod 201 is released by the limit block 4, and the torsion plate 203 is rotated in the opposite direction to drive the positioning rod 201 to rotate, so that the engagement relationship between the positioning rod 201 and the positioning component 3 is released. The positioning rod 201 and the positioning plate 202 are simultaneously disengaged from the inner wall of the shackle structure 1. The entire operation is completed by the linkage structure of the fixing mechanism 2 without the need for additional tools, which greatly shortens the disassembly time, simplifies the operation procedures in frequent loading and unloading scenarios, and improves the efficiency and convenience of operation.
[0031] Specifically, such as Figure 4 As shown, the positioning component 3 includes a connecting block 301 and a limiting plate 302. The side of the connecting block 301 closest to the shackle structure 1 is fixedly connected to the shackle structure 1, and the side of the limiting plate 302 closest to the connecting block 301 is fixedly connected to the connecting block 301.
[0032] Specifically, such as Figure 4As shown, the surface of the connecting block 301 is movably connected to the inner wall of the positioning rod 201, and the surface of the limiting plate 302 is engaged with the inner wall of the positioning rod 201.
[0033] Specifically, such as Figure 3 As shown, the inner wall of the positioning rod 201 is provided with a movable groove 5 that cooperates with the connecting block 301, and the inner wall of the positioning rod 201 is provided with a limiting groove 6 that cooperates with the limiting block 4.
[0034] In this embodiment: By setting a connecting block 301 and a limiting plate 302, the connecting block 301 provides axial guidance for the positioning rod 201, ensuring that the positioning rod 201 is accurately inserted into the shackle structure 1. The limiting plate 302 engages with the inner wall of the positioning rod 201, and together with the connecting block 301, restricts the radial displacement of the positioning rod 201, facilitating rapid pre-installation. The movable groove 5 opened on the inner wall of the positioning rod 201 allows the connecting block 301 to move within the inner wall of the positioning rod 201. The limiting groove 6 opened on the inner wall of the positioning rod 201 allows the limiting block 4 to engage with the inner wall of the positioning rod 201, preventing axial movement after the fixing mechanism 2 is connected to the shackle structure 1, improving the overall connection strength and stability, and ensuring the structural reliability of the shackle under load conditions.
[0035] Specifically, such as Figure 5 , Figure 6 As shown, a spring telescopic assembly 7 is fixedly connected to the bottom of the limiting block 4, and the bottom of the spring telescopic assembly 7 is fixedly connected to the inner wall of the positioning rod 201.
[0036] Specifically, such as Figure 6 , Figure 7 As shown, a pull block 8 is fixedly connected to the front side of the limiting block 4, and the surface of the pull block 8 is movably connected to the inner wall of the shackle structure 1.
[0037] In this embodiment: by setting the spring telescopic component 7, the limiting block 4 is provided with reset power. After the positioning rod 201 is in place, the spring telescopic component 7 drives the limiting block 4 to automatically lock into the limiting groove 6, thereby achieving quick locking and simplifying the installation process. The pull block 8 serves as an operating component, which facilitates the manual application of external force to make the limiting block 4 disengage from the limiting groove 6 and complete the unlocking. The overall structure can shorten the operation time and avoid damage to the shackle structure 1 by tools, thereby improving the efficiency and reusability of the shackle in frequent loading and unloading scenarios.
[0038] Specifically, such as Figure 2 , Figure 7 As shown, a reinforcing plate 9 is provided on the front side of the shackle structure 1, and the surface of the pull block 8 is engaged with the inner wall of the reinforcing plate 9.
[0039] Specifically, such as Figure 5 , Figure 7As shown, a metal block 10 is fixedly connected to the inner wall of the shackle structure 1, and a magnetic block 11 is fixedly connected to the inner wall of the reinforcing plate 9. The rear side of the magnetic block 11 is magnetically connected to the front side of the metal block 10.
[0040] In this embodiment: By setting up a reinforcing plate 9, the reinforcing plate 9 forms physical protection for the pull block 8, preventing the pull block 8 from being accidentally moved due to collision or friction during operation, avoiding accidental unlocking of the limit block 4, and improving the safety of the shackle. The magnetic block 11 and the metal block 10 are magnetically attracted to each other, so that the reinforcing plate 9 can be quickly installed and removed without affecting the normal operation of the pull block 8. This design ensures the stability of the pull block 8 in the non-operational state, while adapting to the needs of efficient operation and enhancing the safety protection and operational flexibility of the shackle during use.
[0041] Working principle: During the use of the shackle structure 1, a fixing mechanism 2 is set up. When in use, the fixing mechanism 2 is inserted into the inner wall of the shackle structure 1. Then, the positioning rod 201 will engage synchronously with the positioning component 3. By rotating the torsion plate 203, the positioning plate 202 and the positioning rod 201 will rotate, so that the positioning component 3 and the positioning rod 201 are precisely engaged to complete the initial positioning. After the positioning rod 201 enters the preset fixed position, the limit block 4 automatically engages into the inner wall of the positioning rod 201 to lock the position. With the help of the structural adaptation of the positioning rod 201 and the limiting effect of the positioning plate 202, the fixing mechanism 2 and the shackle structure are fixed. The continuous and rapid installation of component 1 ensures the accuracy and structural stability of the assembly process. By setting a limit block 4, during subsequent disassembly, the locking state of the positioning rod 201 is released by the limit block 4, and the torsion plate 203 is rotated in the opposite direction to drive the positioning rod 201 to rotate, so that the engagement relationship between the positioning rod 201 and the positioning component 3 is released. The positioning rod 201 and the positioning plate 202 are simultaneously disengaged from the inner wall of the shackle structure 1. The entire operation is completed by the linkage structure of the fixing mechanism 2 without the need for additional tools, which greatly shortens the disassembly time, simplifies the operation procedures in frequent loading and unloading scenarios, and improves the efficiency and convenience of operation.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
