Connecting components are provided on both sides of the upper end plate. A telescopic component is fixedly connected to the other end of each connecting component. An anti-sway component is fixedly connected to the lower end of each telescopic component. The anti-sway component includes a mounting plate located at the lower end of the telescopic component. Fixing plates are fixedly connected to the inner side of each mounting plate. An mounting groove is formed at the other end of each fixing plate. An anti-sway spring is fixedly connected inside the mounting groove. A push plate is fixedly connected to the other end of the anti-sway spring. A contact plate is fixedly connected to the other end of the push plate. The contact plate is movably connected to the lifting sling body.

[0007] As a preferred technical solution, the connecting component includes connecting grooves disposed on both sides of the lower end of the upper plate, and a connecting block is fixedly connected to one end of the telescopic component, and the connecting block and the connecting groove are interlocked.

[0008] As a preferred technical solution, circular grooves are provided on both sides of the connecting block, and connecting springs are fixedly connected inside the circular grooves. A snap-fit ​​connector is fixedly connected to the other end of the connecting spring. Snap-fit ​​holes are provided on both sides of the connecting groove, and the snap-fit ​​connectors and snap-fit ​​holes snap into each other.

[0009] As a preferred technical solution, both sides of the telescopic component are fixedly connected to mounting edges, and the surfaces of the mounting edges are provided with mounting through holes. Mounting screws are inserted into the interior of the mounting through holes, and the mounting screws pass through the mounting through holes and are threadedly connected to the connecting blocks.

[0010] As a preferred technical solution, release springs are fixedly connected to both sides of the upper end plate, and release plates are fixedly connected to the other end of the release springs. Release blocks are fixedly connected to the inner side of the contact plates, and the release blocks are inserted into the locking holes.

[0011] As a preferred technical solution, the telescopic component includes a telescopic sleeve plate disposed at the other end of the connecting component, and a telescopic groove is provided at the other end of the telescopic sleeve plate, and a telescopic movable plate is inserted into the inside of the telescopic groove.

[0012] As a preferred technical solution, a telescopic spring is fixedly connected inside the telescopic movable plate, and a telescopic head is fixedly connected to the other end of the telescopic spring. Multiple telescopic holes are opened on the outer surface of the telescopic sleeve plate, and the telescopic head is engaged with the telescopic holes.

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

[0014] First, this utility model, through the anti-sway component, can be used by connecting the telescopic component and the anti-sway component to the upper plate via the connecting component. After installation, the anti-sway component is located on both sides of the lifting sling body, and then the anti-sway component can be used. When the lifting sling body swings, it will first touch the contact plate. After the contact plate is pressured, it moves into the mounting groove at the other end of the fixed plate. When the push plate moves into the mounting groove, it can be buffered by the anti-sway spring, thereby preventing the lifting sling body from continuing to swing, thus achieving the anti-sway effect of the lifting sling body. In addition, the anti-slip protrusions can prevent slippage when the item is hung on the inner side of the lower hanging ring.

[0015] Secondly, this utility model, through the telescopic component, allows for adjustment of the anti-sway component's position based on the length of the hoisting sling body. During adjustment, the telescopic head is pressed downwards to allow it to enter the telescopic movable plate. Once inside, the telescopic head releases its latch from the telescopic hole, allowing for adjustment of the telescopic movable plate. This adjustment, in turn, allows for adjustment of the distance of the anti-sway component, enabling flexible adjustment of the anti-sway component according to actual conditions and increasing the device's practicality.

[0016] Third, the connecting component of this utility model allows for easy installation of the telescopic component. When the connecting block is inserted into the connecting groove, the snap-fit ​​connector is pressed into the groove. After the connecting block is fully inserted, the snap-fit ​​hole aligns with the groove. The snap-fit ​​connector then springs out of the groove under the action of the connecting spring, engaging with the snap-fit ​​hole to achieve the desired engagement. This allows for the installation of the telescopic component. Conversely, during disassembly, pressing the contact plate moves the release block into the snap-fit ​​hole. This movement pushes the snap-fit ​​connector out of the hole, disengaging it and allowing for the disassembly of the telescopic component. Attached Figure Description

[0022] Example

[0023] refer to Figures 1 to 4 This embodiment of a flat, anti-slip lifting sling includes an upper plate 1, an upper hanging ring 2 fixedly connected to the upper end of the upper plate 1, a lifting sling body 3 fixedly connected to the lower end of the upper plate 1, a lower plate 4 fixedly connected to the lower end of the lifting sling body 3, a lower hanging ring 5 fixedly connected to the lower end of the lower plate 4, an anti-slip protrusion 15 fixedly connected to the inner side of the lower hanging ring 5, connecting components 8 on both sides of the upper plate 1, a telescopic component 6 fixedly connected to the other end of the connecting component 8, an anti-sway component 7 fixedly connected to the lower end of the telescopic component 6, the anti-sway component 7 including a mounting plate 71 disposed at the lower end of the telescopic component 6, a fixing plate 72 fixedly connected to the inner side of the mounting plate 71, an anti-sway spring 74 fixedly connected to the other end of the fixing plate 72, a push plate 75 fixedly connected to the other end of the anti-sway spring 74, a contact plate 76 fixedly connected to the other end of the push plate 75, and the contact plate 76 movably connected to the lifting sling body 3.

[0024] refer to Figure 1 , Figure 2 and Figure 4 The connecting component 8 includes connecting grooves 81 located on both sides of the lower end of the upper plate 1. One end of the telescopic component 6 is fixedly connected to a connecting block 82, which is inserted into the connecting groove 81. Circular grooves 83 are provided on both sides of the connecting block 82, and connecting springs 84 are fixedly connected inside each circular groove 83. A snap-fit ​​connector 85 is fixedly connected to the other end of the connecting spring 84. Snap-fit ​​holes 86 are provided on both sides of the connecting groove 81, and the snap-fit ​​connector 85 snaps into the snap-fit ​​holes 86. When the connecting block 82 is inserted into the connecting groove 81, the snap-fit ​​connector 85 is squeezed into the circular groove 83. After the connecting block 82 is fully inserted into the connecting groove 81, the position of the snap-fit ​​hole 86 is aligned with the position of the circular groove 83. At this time, the snap-fit ​​connector 85 will pop out of the circular groove 83 under the action of the connecting spring 84, so that the snap-fit ​​connector 85 snaps into the snap-fit ​​hole 86, thereby achieving the snap-fit ​​effect and enabling the installation of the telescopic component 6.

[0025] refer to Figure 4 Both sides of the telescopic component 6 are fixedly connected to mounting edges 12. The surface of each mounting edge 12 is provided with mounting through holes 13. Mounting screws 14 are inserted into the mounting through holes 13. The mounting screws 14 pass through the mounting through holes 13 and are threadedly connected to the connecting block 82. The mounting screws 14 enable the telescopic component 6 to be disassembled and assembled, which saves costs when replacing parts of the device and avoids the situation where the entire part needs to be replaced due to the damage of a single part.

[0026] refer to Figure 4 Both sides of the upper plate 1 are fixedly connected to release springs 9, and the other end of the release springs 9 is fixedly connected to release plate 10. The inner side of the contact plate 76 is fixedly connected to release blocks 11, and the release blocks 11 are inserted into the locking holes 86. At the same time, when disassembling, pressing the contact plate 76 causes the release blocks 11 to move into the locking holes 86. When the release blocks 11 move into the locking holes 86, the locking connector 85 can be pushed out of the locking holes 86, thereby disengaging the locking connector 85 from the locking holes 86 and thus enabling the telescopic component 6 to be disassembled.

[0027] refer to Figure 1 and Figure 3 The telescopic component 6 includes a telescopic sleeve plate 61 disposed at the other end of the connecting component 8. A telescopic groove 66 is formed at the other end of the telescopic sleeve plate 61, and a telescopic movable plate 62 is inserted into the telescopic groove 66. A telescopic spring 63 is fixedly connected inside the telescopic movable plate 62, and a telescopic head 64 is fixedly connected to the other end of the telescopic spring 63. Multiple telescopic holes 65 are formed on the outer surface of the telescopic sleeve plate 61, and the telescopic head 64 is engaged with the telescopic holes 65. By pressing down on the telescopic head 64, it enters the interior of the telescopic movable plate 62. After the telescopic head 64 enters the interior of the telescopic movable plate 62, the engagement between the telescopic head 64 and the telescopic holes 65 is released. This release allows for adjustment of the telescopic movable plate 62, thereby adjusting the distance of the anti-sway component 7. This allows for flexible adjustment of the anti-sway component 7 according to actual conditions, increasing the practicality of the device.

[0028] Operating principle and advantages: First, by inserting the connecting block 82 into the connecting groove 81, the snap-fit ​​connector 85 is squeezed into the circular groove 83 during insertion. Then, after the connecting block 82 is fully inserted into the connecting groove 81, the position of the snap-fit ​​hole 86 is aligned with the position of the circular groove 83. At this time, the snap-fit ​​connector 85 will pop out of the circular groove 83 under the action of the connecting spring 84, so that the snap-fit ​​connector 85 and the snap-fit ​​hole 86 can be snapped together, thus achieving the snap-fit ​​effect. This allows the telescopic component 6 to be installed. After installation, the upper hanging ring 2 of the hoisting sling is connected to the equipment, and the lower hanging ring 5 is connected to the item. Then, the equipment can be started to hoist the item through the hoisting sling body 3. During use, when the hoisting sling body 3 swings, it will first touch the contact plate 76. After being pressured, the contact plate 76 moves into the mounting groove 73 at the other end of the fixed plate 72. When the push plate 75 moves into the mounting groove 73, it can be buffered by the anti-sway spring 74, thus preventing the hoisting. As the sling body 3 continues to swing, the anti-sway effect of the sling body 3 can be achieved. During use, the position of the anti-sway component 7 can be adjusted according to the length of the sling body 3. During adjustment, the telescopic head 64 is pressed downwards to enter the telescopic movable plate 62. After the telescopic head 64 enters the telescopic movable plate 62, the latch between the telescopic head 64 and the telescopic hole 65 is released. This release allows for adjustment of the telescopic movable plate 62, thereby adjusting the distance of the anti-sway component 7. This allows for flexible adjustment of the anti-sway component 7 according to actual conditions, increasing the practicality of the device. Simultaneously, during disassembly, pressing the contact plate 76 moves the release block 11 into the latching hole 86. As the release block 11 moves into the latching hole 86, the latching connector 85 is pushed out of the latching hole 86, thus releasing the latching connector 85 from the latching hole 86 and allowing for disassembly of the telescopic component 6.
