Description

Technical Field

[0001] This utility model belongs to the field of sling technology, and specifically relates to a multi-purpose flexible polyester woven sling. Background Technology

[0002] Flexible polyester braided slings are lifting tools made from high-strength polyester fibers using a special weaving process. Combining the superior properties of polyester with a flexible design, they are lightweight, high-strength, wear-resistant, and corrosion-resistant. Widely used in heavy lifting, industrial handling, and construction, these slings utilize high-strength polyester fibers, offering high tensile strength and load-bearing capacity. At the same time, they weigh only 1 / 7 of traditional steel lifting equipment, making them easy to operate and carry. Suitable for lifting precision equipment and fragile items, they reduce the risk of damage to the lifted objects.

[0003] Announcement No. "CN215402561U" discloses a multi-purpose, high-load flexible polyester sling, comprising a sling body, a lifting ring at the top of the sling body, and a protective cover fitted onto the surface of the lifting ring at the connection point between the lifting rings. A limit groove is symmetrically formed on the surface of the lifting ring at the connection point between the lifting ring and the protective cover, and a limit block is provided inside the limit groove. The limit block is fixedly connected to the protective cover. A hook is provided at the bottom of the sling body, and a first limit rod is provided inside the hook. The top of the first limit rod is connected to the hook by a pivot. The design of the protective cover, limit block, and limit groove improves the original direct engagement between the lifting ring and the sling body, which suffers from wear after long-term use. This structure reduces direct wear at the connection point, increasing safety during use.

[0004] Although the above-mentioned utility model improves the direct engagement between the lifting ring and the sling body, which was subject to wear after long-term use, and reduces the direct wear at the connection point between the two by the structure, thus increasing the safety of use, the sling body length cannot be adjusted according to the needs of different lifting tasks because the two ends of the sling are fixedly connected to the lifting ring and the connecting ring. This makes it unsuitable for different sizes of goods or lifting environments, thus limiting the scope of use of the sling. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a multi-purpose flexible polyester braided sling to solve the problem that the length of the sling cannot be adjusted according to the needs of different lifting tasks because the two ends of the sling are fixedly connected to the lifting rings and connecting rings, thus limiting the scope of use of the sling.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A multi-purpose flexible polyester braided sling includes a sling body, with a first connector and a second connector movably connected to both ends of the sling body, and through holes symmetrically opened on the top of the sling body. Fixing components are installed on the top of both the first connector and the second connector, and an assembly block is fixedly connected to the other end of the first connector. A connecting component is installed inside the assembly block.

[0008] The fixed assembly includes a threaded post, a driven gear, a drive gear, a rotating post, and a first threaded hole. The top of both the first and second connectors is rotatably connected to the drive gear. The center of the top of the drive gear is fixedly connected to the rotating post. The top of both the first and second connectors is symmetrically rotatably connected to the driven gear. The driven gear meshes with the drive gear. The top of the driven gear has a first threaded hole, and the threaded post is threadedly connected inside the first threaded hole. By changing the sling body of different lengths, it can easily handle the switching between short-distance handling and long-distance hoisting without replacing the entire hoisting system. Moreover, it can be quickly disassembled and assembled without tools, and the length adjustment can be completed by a single person, saving time and manpower.

[0009] As a preferred technical solution, both the first connector and the second connector have slots at one end. The sling body is inserted into the slot. The bottom of the slot has symmetrical second threaded holes. The threaded post is threaded through the through hole and the second threaded hole. The tight connection is achieved through mechanical engagement. The tensile strength is significantly higher than that of ordinary buckle or plug-in designs, which prevents loosening during hoisting.

[0010] As a preferred technical solution, the connecting assembly includes a cavity, a return spring, a movable plate, and a locking block. The assembly block has symmetrically shaped cavities inside. A return spring is fixedly connected to one side of each cavity, and a movable plate is fixedly connected to the other end of the return spring. The movable plate is slidably connected to the cavity. A locking block is fixedly connected to the side of the movable plate away from the return spring. The other end of the locking block extends out of the side of the assembly block. One end of the locking block has a bevel. One end of the second connecting head has an assembly groove. The assembly block and the assembly groove are plugged in. Locking grooves are formed on both sides of the assembly groove. The locking block and the locking groove are snapped together. An unlocking block is slidably connected inside the locking groove. The other end of the unlocking block extends out of the side of the second connecting head. Limit blocks are fixedly connected to both sides of the unlocking block. Limit grooves are formed on both sides of the locking groove. The limit blocks and limit grooves are slidably connected, allowing the two ends of the sling to form a closed loop without end points after snapping together. This avoids stress concentration caused by end openings in traditional slings, improves overall load uniformity, and is compatible with various lifting equipment such as hooks and pulleys, achieving stable lifting.

[0011] As a preferred technical solution, the top and bottom of the assembly block are symmetrically provided with positioning grooves, and positioning blocks are symmetrically fixedly connected to the top and bottom of the assembly groove. The positioning blocks and the positioning groove are slidably connected, which can limit the rotation or lateral movement of the connector, ensure that the position is consistent each time they are merged, and avoid uneven force or loose connection caused by misalignment.

[0012] As a preferred technical solution, metal edge banding strips are symmetrically installed on both sides of the sling body. The metal edge banding strips are fixedly connected to the sling body, which can significantly improve the tear resistance of the sling edges and prevent the risk of breakage under heavy load or complex working conditions.

[0013] In summary, the present invention has the following main advantages:

[0014] First, in this utility model, the two ends of the sling body are respectively inserted into the slots on one side of the first connector and the second connector. Then, the rotating column is rotated to control the drive gear to rotate. The drive gear drives the driven gear to rotate. When the driven gear rotates, the first threaded hole and the threaded column rotate, thereby controlling the threaded column to descend. The threaded column passes through the through hole on the sling body and is threadedly connected to the second threaded hole. By changing the sling body of different lengths, it can easily handle the switching between short-distance handling and long-distance hoisting without replacing the entire hoisting system. Moreover, it can be quickly disassembled and assembled without tools. The length adjustment can be completed by a single person, saving time and manpower.

[0015] Secondly, in this utility model, the first connector and one end of the second connector are merged, so that the assembly block is inserted into the assembly groove. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the moving plate to press against the return spring. The return spring is compressed, and at the same time, the locking block retracts into the cavity. When the locking block moves to the locking groove, the return spring resets, and the locking block pops out and engages with the locking block for fixation. This allows the connectors at both ends of the sling to form a closed loop without end points after engagement, avoiding stress concentration caused by the end opening of traditional slings, improving the overall load uniformity, and being compatible with various lifting equipment such as hooks and pulleys, achieving stable lifting.

[0024] The fixing assembly 11 includes a threaded post 111, a driven gear 112, a drive gear 113, a rotating post 114, and a first threaded hole 115. The tops of the first connector 4 and the second connector 5 are rotatably connected to the drive gear 113. The center of the top of the drive gear 113 is fixedly connected to the rotating post 114. The tops of the first connector 4 and the second connector 5 are symmetrically rotatably connected to the driven gear 112, which meshes with the drive gear 113. The top of the driven gear 112 has a first threaded hole 115, and the threaded post 111 is threaded into the first threaded hole 115. One end of the first connector 4 and the second connector 5 has a slot 10. The body 1 is inserted into the slot 10. The bottom of the slot 10 is symmetrically provided with a second threaded hole 17. The threaded post 111 passes through the through hole 3 and is threadedly connected to the second threaded hole 17. The two ends of the sling body 1 are respectively inserted into the slot 10 on the side of the first connector 4 and the second connector 5. Then, the rotating post 114 is rotated to control the drive gear 113 to rotate. The drive gear 113 drives the driven gear 112 to rotate. When the driven gear 112 rotates, the first threaded hole 115 and the threaded post 111 rotate threadedly, thereby controlling the threaded post 111 to descend. The threaded post 111 passes through the through hole 3 on the sling body 1 and is threadedly connected to the second threaded hole 17.

[0025] refer to Figures 4 to 5 The connecting assembly 12 includes a cavity 121, a return spring 122, a movable plate 123, and a locking block 124. The assembly block 6 has symmetrically arranged cavities 121 inside. A return spring 122 is fixedly connected to one side of each cavity 121, and a movable plate 123 is fixedly connected to the other end of the return spring 122. The movable plate 123 is slidably connected to the cavity 121. A locking block 124 is fixedly connected to the side of the movable plate 123 away from the return spring 122. The other end of the locking block 124 extends out of the side of the assembly block 6. One end of the locking block 124 has a bevel. One end of the second connecting head 5 has an assembly groove 7. The assembly block 6 and the assembly groove 7 are... The assembly slot 7 has locking grooves 13 on both sides. The locking block 124 is snapped into the locking groove 13. The first connector 4 and the second connector 5 are joined together so that the assembly block 6 is inserted into the assembly slot 7. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 124, causing the locking block 124 to drive the moving plate 123 to press against the return spring 122. The return spring 122 is compressed, and at the same time, the locking block 124 retracts into the cavity 121. When the locking block 124 moves to the locking groove 13, the return spring 122 returns to its original position, and the locking block 124 pops out and is snapped into place.

[0026] refer to Figure 5 An unlocking block 16 is slidably connected inside the locking groove 13. The other end of the unlocking block 16 extends to the side end of the second connector 5. Limiting blocks 14 are fixedly connected to both sides of the unlocking block 16. Limiting grooves 15 are opened on both sides inside the locking groove 13. The limiting blocks 14 and the limiting grooves 15 are slidably connected. Pushing the unlocking block 16 causes it to slide inside the locking groove 13. At the same time, the unlocking block 16 drives the limiting blocks 14 to slide inside the limiting grooves 15. The unlocking block 16 pushes the locking block 124, causing the locking block 124 to drive the moving plate 123 to press against the return spring 122. The return spring 122 is compressed. At the same time, the locking block 124 retracts into the cavity 121. The locking block 124 and the locking groove 13 are no longer engaged. Pulling the first connector 4 causes the assembly block 6 and the assembly groove 7 to be no longer inserted.

[0027] refer to Figure 3 and Figure 5 The assembly block 6 has symmetrically opened positioning grooves 9 at the top and bottom. The assembly groove 7 has symmetrically fixedly connected positioning blocks 8 at the top and bottom. The positioning blocks 8 and the positioning grooves 9 are slidably connected. The first connector 4 and the second connector 5 are merged so that the assembly block 6 is inserted into the assembly groove 7. At the same time, the positioning blocks 8 and the positioning grooves 9 are slidably connected.

[0028] refer to Figure 1Metal edge sealing strips 2 are symmetrically installed on both sides of the sling body 1. The metal edge sealing strips 2 are fixedly connected to the sling body 1. The metal edge sealing strips 2 can significantly improve the tear resistance of the sling edge and prevent the risk of breakage under heavy load or complex working conditions.

[0029] Operating principle and advantages: First, insert both ends of the sling body 1 into the slots 10 on one side of the first connector 4 and the second connector 5, respectively. Then, rotate the rotating column 114 to control the drive gear 113 to rotate. The drive gear 113 drives the driven gear 112 to rotate. When the driven gear 112 rotates, it causes the first threaded hole 115 to rotate with the threaded column 111, thereby controlling the threaded column 111 to descend. The threaded column 111 passes through the through hole 3 on the sling body 1 and rotates with the second threaded hole 17. The first connector 4 and the second connector 5 are then joined together, so that the assembly block 6 is inserted into the assembly groove 7. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 124, so that the locking block 124 drives the moving plate 123 to press against the return spring 122. The return spring 122 is compressed, and at the same time the locking block 124 retracts into the cavity 121. When the locking block 124 moves to the locking groove 13, the return spring 122 is reset, and the locking block 124 pops out and is locked in place.

[0030] This utility model can easily handle the switching between short-distance handling and long-distance hoisting by changing the sling body 1 of different lengths, without replacing the entire hoisting system. Moreover, it can be quickly disassembled and assembled without tools, and the length can be adjusted by a single person, saving time and manpower.
