Description

Technical Field

[0001] The utility model relates to the technical field of rigging rings, in particular to a rigging ring with an anti-falling structure. Background Art

[0002] A rigging eye is a buckle used to carry various equipment, machines and components, usually used in lifting, hanging and installation. A rigging eye has a certain load-bearing capacity, and there are many types of rigging eyes. A swivel eye is one of the rigging eyes, and the swivel eye can rotate. Existing rigging eyes still have certain defects when in use.

[0003] In the prior art, rigging rings can be installed on objects to hang and move the objects with the help of slings. They can also be installed on various equipment and parts. In actual applications, the rigging rings may indeed fall off. When people use the rigging rings, if the hexagonal bolts are not fixed firmly enough and the hoisted goods are heavy, the hexagonal bolts may easily loosen, making the hoisted goods easy to fall off, thereby causing unnecessary losses. Utility Model Content

[0004] The utility model aims to provide a rigging ring with an anti-falling structure to solve the problem that the external hexagonal bolts on the rigging rings on the current market are easy to loosen, as mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rigging lifting ring with an anti-falling structure, comprising: a hook, a lifting ring body, a rotating sleeve, an I-block and an external hexagonal bolt, the lifting ring body is suspended on the inner side of the hook, the outer side of the lifting ring body is rotatably connected to the rotating sleeve, the interior of the rotating sleeve is rotatably connected to the I-block, and the interior of the I-block is penetrated by an external hexagonal bolt.

[0006] Preferably, a connecting rod is welded on the surface of the rotating sleeve, the connecting rod and the interior of the rotating sleeve are slidably connected to a sliding column, the bottom end of the sliding column is connected to the connecting column via a rotating shaft, and the interior of the connecting column is threadedly connected to a knob.

[0007] Preferably, a connecting block is welded to the outer side of the sliding column, a fixing block is welded to the end of the connecting block, a rotating seat is rotatably connected to the inside of the fixing block, and a hexagonal anti-slip sleeve is welded to the bottom end of the rotating seat.

[0008] Preferably, the sliding column forms a rotating sliding structure with the rotating sleeve and the connecting rod respectively, and the inner diameter of the hexagonal anti-slip sleeve matches the outer diameter of the hexagonal bolt.

[0009] Preferably, a connecting frame is provided at the bottom of the I-shaped block, and a thickened rubber block is bonded to the inner wall of the connecting frame.

[0010] Preferably, a fixing rod is connected inside the connection frame, and a rotating block is rotatably connected outside the fixing rod.

[0011] Preferably, a spring is connected between the rotating block and the connecting frame, and a clamping block is installed on a side of the rotating block close to the I-shaped block.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the rigging lifting ring with an anti-falling structure can drive the sliding column and the inner hexagon anti-slip sleeve to move when the connecting block moves, and can drive the connecting column to slide into the rotating sleeve when the sliding column moves. When the inner hexagon anti-slip sleeve rises to a height higher than the outer hexagon bolt, the sliding column can be rotated so that the inner hexagon anti-slip sleeve is located directly above the outer hexagon bolt. When the outer hexagon bolt is docked and fixed to the equipment, the thickened rubber block can produce extrusion deformation. The thickened rubber block can prevent the bottom of the I-beam block from directly contacting the surface of the equipment, so that the surface of the equipment is not easily damaged during lifting.

[0013] 1. Rigging rings are common in lifting and hoisting operations. When the hexagonal bolts on the rigging rings are not fixed firmly enough, there is a risk of cargo falling off. When the connecting block moves, the sliding column and the hexagonal anti-slip sleeve can be driven to move. When the sliding column moves, the connecting column can be driven to slide into the inside of the rotating sleeve. When the height of the hexagonal anti-slip sleeve is higher than the hexagonal bolt, the sliding column can be rotated so that the hexagonal anti-slip sleeve is located directly above the hexagonal bolt. When the hexagonal anti-slip sleeve is rotated to the specified position, it can just fall on the outside of the hexagonal bolt. At this time, the hexagonal anti-slip sleeve can limit the hexagonal bolt. The connecting column can be rotated through the rotating shaft. When the connecting column rotates and moves to the bottom surface of the rotating sleeve, the knob can be passed through the connecting column so that the knob can be threadedly fixed with the rotating sleeve. When the hexagonal bolt is loose, the hexagonal anti-slip sleeve can prevent the hexagonal bolt from loosening and rotating, so that the hoisted equipment is not easy to fall off due to the loosening of the hexagonal bolt, thereby improving the safety of the use of rigging rings.

[0014] 2. When the rigging lifting ring is docked and fixed to the equipment, the I-block is easy to squeeze the surface of the equipment, causing the surface of the equipment to be easily damaged. When the rotating block moves, it can be rotated by the fixed rod, and when the rotating block rotates, the spring can be stretched. When the spring is stretched to a specified degree, the connecting frame and the thickened rubber block can be sleeved on the outside of the hexagonal bolt. When the two sets of rotating blocks are loosened, they can be reset by the spring. When the two sets of rotating blocks are reset, the end of the card block can be driven to engage with the inside of the I-block, so that the connecting frame and the thickened rubber block are installed at the bottom of the I-block. When the hexagonal bolt is docked and fixed to the equipment, the thickened rubber block can produce extrusion deformation. The thickened rubber block can prevent the bottom of the I-block from directly contacting the surface of the equipment, so that the surface of the equipment is not easily damaged during lifting.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 4 It can be seen that the utility model provides a technical solution: a rigging ring with an anti-falling structure, comprising: a hook 1, a ring body 2, a rotating sleeve 3, an I-shaped block 4 and an external hexagonal bolt 5, the inner side of the hook 1 is suspended with the ring body 2, the outer side of the ring body 2 is rotatably connected with the rotating sleeve 3, the inner side of the rotating sleeve 3 is rotatably connected with the I-shaped block 4, the inner side of the I-shaped block 4 is penetrated and connected with the external hexagonal bolt 5, the surface of the rotating sleeve 3 is welded with a connecting rod 6, and the connecting rod 6 is slidably connected with the inner side of the rotating sleeve 3 There is a sliding column 7, the bottom end of the sliding column 7 is connected to a connecting column 8 through a rotating shaft, the internal thread of the connecting column 8 is connected to a knob 9, a connecting block 10 is welded to the outside of the sliding column 7, a fixed block 11 is welded to the end of the connecting block 10, the internal rotation of the fixed block 11 is connected to a rotating seat 12, and the bottom end of the rotating seat 12 is welded to an inner hexagonal anti-skid sleeve 13, the sliding column 7 and the rotating sleeve 3 and the connecting rod 6 respectively form a rotating and sliding structure, and the inner diameter size of the inner hexagonal anti-skid sleeve 13 matches the outer diameter size of the outer hexagonal bolt 5.

[0022] In specific implementation, rigging rings are more common in lifting and hoisting operations. When the outer hexagonal bolt 5 on the rigging ring is not fixed firmly enough, the risk of cargo falling off is likely to occur. When the outer hexagonal bolt 5 is fixed to the equipment thread, the connecting block 10 can be pulled upward. When the connecting block 10 moves, the sliding column 7 and the inner hexagonal anti-slip sleeve 13 can be driven to move. When the sliding column 7 moves, it can drive the connecting column 8 to slide into the rotating sleeve 3. When the inner hexagonal anti-slip sleeve 13 rises to a height higher than the outer hexagonal bolt 5, the sliding column 7 can be rotated so that the inner hexagonal anti-slip sleeve 13 is located Directly above the external hexagonal bolt 5, the internal hexagonal anti-slip sleeve 13 can be rotated at this time. When the internal hexagonal anti-slip sleeve 13 rotates, it can drive the rotating seat 12 to rotate inside the fixed block 11. When the internal hexagonal anti-slip sleeve 13 rotates to the specified position, it can just fall on the outside of the external hexagonal bolt 5. At this time, the internal hexagonal anti-slip sleeve 13 can limit the external hexagonal bolt 5, and the connecting column 8 can be rotated through the rotating shaft. When the connecting column 8 rotates and moves to the bottom surface of the rotating sleeve 3, the knob 9 can be passed through the connecting column 8, so that the knob 9 can be threadedly fixed to the rotating sleeve 3.

[0023] See also Figure 1 , Figure 2 and Figure 4 It can be seen that when the outer hexagonal bolt 5 is loosened, the inner hexagonal anti-slip sleeve 13 can prevent the outer hexagonal bolt 5 from loosening and rotating, so that the hoisted equipment is not easy to fall off due to the loosening of the outer hexagonal bolt 5, thereby improving the safety of the use of the rigging eye.

[0024] See also Figure 1 , Figure 2 and Figure 3 It can be seen that a connecting frame 14 is provided at the bottom of the I-shaped block 4, a thickened rubber block 15 is bonded to the inner wall of the connecting frame 14, a fixing rod 16 is connected to the inside of the connecting frame 14, a rotating block 17 is rotatably connected to the outer side of the fixing rod 16, a spring 18 is connected between the rotating block 17 and the connecting frame 14, a clamping block 19 is installed on the side of the rotating block 17 close to the I-shaped block 4, and the connecting frame 14 is made of wood.

[0025] During specific implementation, when the rigging eye is docked and fixed with the equipment, the I-block 4 is easy to squeeze the surface of the equipment, causing the surface of the equipment to be easily damaged. For this reason, the two groups of rotating blocks 17 can be pulled away from each other. When the rotating block 17 moves, it can be rotated by the fixed rod 16, and when the rotating block 17 rotates, the spring 18 can be stretched. When the spring 18 is stretched to a specified degree, the connecting frame 14 and the thickened rubber block 15 can be sleeved on the outside of the hexagonal bolt 5, so that the thickened rubber block 15 is located on the bottom surface of the I-block 4. At this time, the two groups of rotating blocks 17 can be loosened. When the two groups of rotating blocks 17 are loosened, they can be reset by the spring 18. When the two groups of rotating blocks 17 are reset, the end of the clamping block 19 can be driven to clamp into the inside of the I-block 4, thereby installing the connecting frame 14 and the thickened rubber block 15 at the bottom of the I-block 4.

[0026] See also Figure 1 , Figure 2 and Figure 3 It can be seen that when the hexagonal bolt 5 is docked and fixed to the equipment, the thickened rubber block 15 can produce extrusion deformation. The thickened rubber block 15 can prevent the bottom of the I-block 4 from directly contacting the surface of the equipment, making it difficult for the surface of the equipment to be damaged during lifting.

[0027] In summary, when the rigging lifting ring with an anti-falling structure is used, the rotating sleeve 3 and the equipment can be fixed together by the external hexagonal bolt 5. At this time, the lifting ring body 2 can be hung on the inner side of the hook 1. When the crane is running, the equipment can be lifted by the rigging lifting ring. The rigging lifting ring is a prior art and will not be described in detail here. When the connecting column 8 is rotated and moved to the bottom surface of the rotating sleeve 3, the knob 9 can be passed through the connecting column 8 so that the knob 9 can be threadedly fixed with the rotating sleeve 3. When the external hexagonal bolt 5 is loosened, the internal hexagonal anti-slip sleeve 13 can prevent the external hexagonal bolt 5 from loosening and rotating, so that the lifted equipment is not easy to fall off due to the loosening of the external hexagonal bolt 5, thereby improving the safety of the use of the rigging lifting ring. When the external hexagonal bolt 5 is docked and fixed with the equipment, the thickened rubber block 15 can produce extrusion deformation. The thickened rubber block 15 can prevent the bottom of the I-shaped block 4 from directly contacting the surface of the equipment, so that the surface of the equipment is not easy to be damaged during lifting. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
