Description

Technical Field

[0001] This utility model relates to the field of shackle technology, specifically a double pin shackle. Background Technology

[0002] A shackle is a connecting tool widely used in mechanical engineering and lifting operations. It is mainly used to securely connect two separate instruments or components together. Shackles are usually made of metal and have the characteristics of simple structure, high safety factor and wide application. Common forms of shackles include D-shaped shackles and bow shackles. D-shaped shackles are also called U-shaped shackles or straight shackles, while bow shackles are called Ω-shaped shackles or horseshoe shackles.

[0003] A shackle is a device used to connect and disconnect mechanical connections. It is widely used in lifting and hoisting applications. A shackle typically consists of a shackle body (large ring) and a cross pin, which can be a screw pin or a plain pin. During use, the shackle needs to be smooth and flat, free from defects such as cracks, sharp edges, and overheating, to ensure its safety and reliability.

[0004] Existing shackles rely on a single pin to ensure their load-bearing capacity and maneuverability. However, when the pin falls off or breaks, there are no protective measures in place, which can cause a stable load to fall and potentially damage the shackle. This limitation makes them less suitable for complex working environments. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a double-pin shackle to solve the technical problem that a shackle with only one pin can guarantee the load-bearing capacity and flexible operation of the shackle. When the pin falls off or breaks, there are no protective measures, which may cause the stable heavy object to fall and cause damage. It is also highly restrictive and has poor applicability in complex working environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double pin shackle, comprising a main body, wherein multiple sets of fixing rings are provided inside the main body, bolts are provided inside the fixing rings, a fixing nut is fixed to one end of the bolt, a nut is provided on the outside of the bolt, a sliding rod is movably connected inside the main body, and a hollow iron ring is provided on the outside of the bolt.

[0007] By adopting the above technical solution, when in use, external personnel fix the concave column set at one end of the main body to the end that provides power from the outside. Then, the end that needs to be moved is put into the main body. Then, multiple sets of fixing rings set on the outside of the main body are used to insert the first set of bolts into the fixing ring. When the bolt touches the internal thread inside the fixing ring, it can start to rotate.

[0008] When the bolt is still loose, the rotation process can be accelerated by the fixing block set on the outside of the bolt. When it has rotated to a certain extent, the tightness of the bolt can be ensured by external tools to ensure the stability of the overall shackle.

[0009] Then, by inserting the two sets of bolts into the fixing ring inside the main body in sequence, and then inserting the second set of bolts into the fixing ring, the movable rod inside the main body will be squeezed, causing the movable rod to move upward as a whole.

[0010] When the movable rod moves upward, it will abut against the groove set inside the first set of bolts, so as to ensure that the first set of bolts cannot be disassembled before the second set of bolts is completely disassembled. This ensures that the two sets of bolts can be installed at the same time. In addition, while accommodating multiple slings, it can also be flexibly adjusted according to the connection angle, reducing wear between the slings and the heavy objects, and improving the safety and efficiency of the lifting operation.

[0011] The above structure ensures that the shackle has two pins to guarantee its load-bearing capacity and flexible operation. Even if the first set of pins falls off or breaks, the other set of bolt pins will still be used to fix it, preventing heavy objects from falling and causing damage.

[0012] Furthermore, the fixing ring has a through hole inside that mates with the bolt, and the fixing ring has an internal thread that mates with the bolt.

[0013] By adopting the above technical solution, the bolt can pass through the retaining ring through the through hole, thereby fixing it and preventing jamming.

[0014] Furthermore, a fixing block is provided at one end of the fixing nut, and the fixing block is fixed to the fixing nut by welding.

[0015] By adopting the above technical solution, the fixing block ensures that the fixing nut can be turned by external personnel when it is relatively loose, thus saving some effort.

[0016] Furthermore, the main body and the fixing ring are connected by a connecting handle, and the main body and the connecting handle are connected by welding.

[0017] By adopting the above technical solution, the connection between the main body and the fixed ring is reinforced by the connecting handle, which can effectively increase its safety and stability performance.

[0018] Furthermore, the main body has a cavity inside that cooperates with the sliding rod, and the hollow iron ring also has a cavity inside.

[0019] By adopting the above technical solution, the cavity ensures that the extrusion block can compress the sliding rod, and the sliding rod has a certain amount of space to move, so as not to cause jamming.

[0020] Furthermore, one set of bolts has a pressing block on its outer side that cooperates with the sliding rod, and the outer side of one set of bolts has a groove that cooperates with the sliding rod.

[0021] By adopting the above technical solution, the compression block can ensure that the sliding rod can move passively when the bolt moves.

[0022] In summary, the present invention has the following beneficial effects: The present invention allows external personnel to fix a concave column on one side of the main body to the power-providing end. Then, the first set of bolt pins is inserted into multiple sets of fixing rings inside the main body, and then rotated to fix the first set of bolt pins within the fixing rings inside the main body. Then, the second set of bolt pins is inserted sequentially, so that the pressing block on the outside of the second set of bolt pins can press against the sliding rod connected to the main body. This ensures that both sets of bolt pins are installed during use. Furthermore, hollow iron rings are located on the outside of the two sets of bolt pins to prevent the bolts from loosening due to friction between the outer chain and the bolts.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A double pin shackle, such as Figures 1-4As shown, the device includes a main body 1. Multiple sets of fixing rings 6 are installed inside the main body 1. Bolts 8 are installed inside the fixing rings 6. A fixing nut 3 is fixed to one end of each bolt 8, and a nut 7 is installed on the outside of each bolt 8. A sliding rod 10 is movably connected inside the main body 1. In use, an external worker fixes the concave post at one end of the main body 1 to the end that provides external power. Then, the end that needs to be moved is fitted inside the main body 1. The first set of bolts 8 is then inserted into the fixing rings 6 on the outside of the main body 1. When the bolt 8 touches the internal thread of the fixing ring 6, it can begin to rotate.

[0031] For example, a hollow iron ring 11 is provided on the outside of the bolt 8, a through hole 5 is provided inside the fixing ring 6 to cooperate with the bolt 8, the fixing ring 6 is provided with an internal thread to cooperate with the bolt 8, and a fixing block 4 is provided at one end of the fixing nut 3. When the bolt 8 is still in a loose state, the rotation process can be accelerated by the fixing block 4 provided on the outside of the bolt 8. When it rotates to a certain extent, the tightness of the bolt 8 can be ensured by external tools to ensure the stability of the overall shackle.

[0032] For example, the fixing block 4 and the fixing nut 3 are fixed by welding, and the main body 1 and the fixing ring 6 are connected by the connecting handle 2. The main body 1 and the connecting handle 2 are connected by welding. Then, by inserting two sets of bolts 8 into the fixing ring 6 inside the main body 1 in sequence, and then inserting the second set of bolts 8 into the fixing ring 6, the movable rod 10 set inside the main body 1 will be squeezed, causing the movable rod 10 to move upward as a whole.

[0033] For example, one set of bolts 8 has a pressing block 12 on its outer side that cooperates with the sliding rod 10, and one set of bolts 8 has a groove 9 on its outer side that cooperates with the sliding rod 10. When the movable rod 10 moves upward, it will abut against the groove 9 inside the first set of bolts 8, so as to ensure that the first set of bolts 8 cannot be disassembled before the second set of bolts 8 is completely disassembled. This ensures that the two sets of bolts 8 can be installed at the same time, and while accommodating multiple slings, it can also be flexibly adjusted according to the connection angle, reducing wear between the slings and the heavy objects, and improving the safety and efficiency of the lifting operation.

[0034] The working principle of this utility model is as follows: When in use, an external worker fixes the concave column at one end of the main body 1 to the end that provides power from the outside. Then, the end that needs to be moved is put into the main body 1. Then, multiple sets of fixing rings 6 set on the outside of the main body 1 are used to insert the first set of bolts 8 into the fixing ring 6. When the bolts 8 touch the internal threads inside the fixing ring 6, they can start to rotate.

[0035] When bolt 8 is still loose, the rotation process can be accelerated by the fixing block 4 set on the outside of bolt 8. When it rotates to a certain extent, the tightness of bolt 8 can be ensured by external tools to ensure the stability of the overall shackle.

[0036] Then, by inserting two sets of bolts 8 into the fixing ring 6 inside the main body 1 in sequence, and then inserting the second set of bolts 8 into the fixing ring 6, the movable rod 10 set inside the main body 1 will be squeezed, causing the movable rod 10 to move upward as a whole.

[0037] When the movable rod 10 moves upward, it will abut against the groove 9 set inside the first set of bolts 8, so as to ensure that the first set of bolts 8 cannot be disassembled before the second set of bolts 8 is completely disassembled. This ensures that the two sets of bolts 8 can be installed at the same time. In addition, while accommodating multiple slings, it can also be flexibly adjusted according to the connection angle, reducing the wear between the slings and the heavy objects, and improving the safety and efficiency of the lifting operation.

[0038] The above structure ensures that the shackle has two pins to guarantee its load-bearing capacity and flexible operation. Even if the first set of pins falls off or breaks, the other set of bolt pins will still be used to fix it, preventing heavy objects from falling and causing damage.
