[0022] As Figure 1 And Figure 2 As shown in a kind of shackle device with anti-theft and anti-unloading function, it is characterized in that: including first shackle arm 1, second shackle arm 2, shackle pin 3 and stop post 4, the first shackle arm 1 connects second shackle arm 2 and forms annular shackle main body, threaded hole 13 is formed on the first shackle arm 1, through hole 23 is formed on the second shackle arm 2, the shackle pin 3 passes through through hole 23 and is connected with threaded hole 13 by screwing, the end of the shackle pin 3 is connected with stop post 4, anti-theft lock is arranged on the stop post 4, and the anti-theft lock is used for the connection and release of shackle pin 3 and stop post 4.
[0023] The anti-theft lock is usually composed of a lock cylinder, a key or a special unlocking tool, and an internal locking mechanism. The lock cylinder is installed at one end of the stop post 4 and connected with the shackle pin 3. The lock cylinder can be a traditional pin tumbler lock, a disc tumbler lock, or a more advanced electronic lock, depending on the security requirements of the application scenario.
[0024] In the normal closed state, the shackle pin 3 passes through the first shackle arm 1 and the second shackle arm 2 through the threaded hole 13 and the through hole 23, and the anti-theft lock on the stop post 4 further locks the shackle pin 3 to prevent it from being accidentally loosened or illegally opened. If you want to open the shackle, you must use a matching key 6 or a special tool to insert into the lock cylinder and operate in a specific way, such as rotating, to release the locked state. Once the lock is released, the shackle pin 3 can be rotated out, allowing the shackle arm and the shackle pin 3 to separate.
[0025] As Figure 3As shown, the first shackle arm 1 includes a first connecting part 11 and a first annular part 12. The first connecting part 11 has a threaded hole 13, and the first annular part 12 is provided with a first protrusion 14 and a first slot 15.
[0026] like Figure 4 As shown, the second shackle arm 2 includes a second connecting portion 21 and a second annular portion 22. The second connecting portion 21 has a through hole 23, and the second annular portion 22 has a second protrusion 24 and a second slot 25. The first protrusion 14 and the second slot 25 are matched, and the second protrusion 24 and the first slot 15 are matched. The first shackle arm 1 and the second shackle arm 2 are interference-fitted. A mechanical interlocking structure is formed by the matching of the first protrusion 14 on the first annular portion 12 with the second slot 25 on the second shackle arm 2, and the matching of the second protrusion 24 on the second annular portion 22 with the first slot 15. Even under external force or vibration, it is difficult to loosen on its own, thus greatly reducing the risk of accidental opening. The design of the protrusion and slot allows the two shackle arms to be quickly aligned and positioned during assembly, simplifying the installation steps and improving work efficiency. At the same time, this design also helps to ensure consistency and accuracy after each assembly. An interference fit means that there is a certain amount of interference between the two components during assembly. This close contact provides additional mechanical restraint, ensuring that the two parts will not easily separate even under heavy loads or impacts. This greatly improves the load-bearing capacity and structural stability of the shackle device.
[0027] The modular design allows for greater flexibility in adapting to different connection requirements. For example, during installation, one shackle arm can be secured to one point first, then another point can be connected, and finally closed with the shackle pin to form a complete loop structure. This is particularly useful for applications requiring operation in confined spaces or alignment of specific locations. Because each part is independent, individual maintenance, inspection, or replacement is easier. If one part is damaged, only that part needs to be replaced instead of the entire shackle, reducing maintenance costs.
[0028] like Figure 5 As shown, the shackle pin 3 includes a rod 31, a retaining ring 33, and a handle 34. The end of the rod 31 is threaded 32, and the retaining ring 33 and handle 34 are fixedly connected to the rod 31. The thread 32 at the end of the rod 31 allows for a secure threaded connection with the threaded hole 13 on the first shackle arm 1. This mechanical connection provides higher connection strength than a simple plug-in connection, ensuring that the two shackle arms will not easily separate during use, thereby improving overall safety.
[0029] The diameter of the blocking ring 33 is greater than the diameter of the through hole 23. The diameter of the shackle pin 3 is smaller than the diameter of the through hole 23. Preferably, the diameter of the threaded hole 13 is greater than the diameter of the through hole 23. The diameter of the stop post 4 is greater than the diameter of the blocking ring 33, which is greater than the diameter of the through hole 23 on the second shackle arm 2. This means that once the shackle pin 3 is inserted and tightened, the blocking ring will prevent the shackle pin from sliding out of the through hole. This effectively prevents accidental release due to vibration or other external forces, enhancing the anti-self-release function. The handle 34 attached to the shank 31 provides a convenient grip and rotation operation site for the user. This not only makes installation and removal easier, but is especially important for users who need to operate frequently or work in complex environments. In addition, the handle can also be designed to be ergonomically shaped to improve the comfort of use.
[0030] The dust cover 5 is provided on the stop post 4, which includes a connecting sleeve 51 and a cover body 52. The connecting sleeve 51 is fitted on the stop post 4, and the cover body 52 is matched in size with the stop post 4. The dust cover 5 effectively blocks dust, sand, moisture and other pollutants from entering the lock core, preventing these substances from affecting the normal operation of the lock. The design of the connecting sleeve 51 and the cover body 52 can be adjusted according to the specific application scenario. When the lock needs to be cleaned or inspected, the dust cover 5 can be easily removed, making it convenient for technicians to perform necessary maintenance work. After maintenance, it can also be quickly reinstalled without affecting normal use.
[0031] If the shackle is in the closed state, first unlock the anti-theft lock with the matching key 6 or tool, remove the stop post 4, and then unscrew the shackle pin 3. Fix the first shackle arm 1 and the second shackle arm 2 to the two points that need to be connected, such as ropes, chains or other hoisting equipment. Ensure that the first protrusion 14 and the second slot 25, as well as the second protrusion 24 and the first slot 15, are accurately mated. Insert the shackle pin 3 through the through hole 23 on the second shackle arm 2, and align the threaded hole 32 at the end of the shank 31 with the threaded hole 13 on the first shackle arm 1. Use the handle 34 to rotate the shackle pin 3 until the blocking ring 33 rests against the second shackle arm 2, and the shackle pin 3 is fully inserted into the threaded hole, forming a secure connection. The final step is to connect the stop post 4 with the shackle pin 3, locking the anti-theft lock on the stop post 4. Lock the lock core by inserting the correct key 6 or using a special tool to ensure that the connection between the shackle pin 3 and the stop post 4 cannot be easily released. Fit the connecting sleeve 51 of the dust cover 5 on the stop post 4, and ensure that the cover body 52 fits tightly, protecting the lock core from external contamination.
[0032] It should be noted that the anti-theft lock, the stop post and the shackle pin of the present embodiment are general standard parts or components known to those skilled in the art, and their structure and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.
