Description

Technical Field

[0001] This utility model relates to the field of sling technology, and in particular to a safety flat buckle type sling. Background Technology

[0002] A sling is a flexible load-bearing device used for lifting, pulling, or securing heavy objects. It is widely used in the fields of hoisting, transportation, construction, shipbuilding, and industry to safely and reliably lift or secure heavy objects. A safety flat buckle sling is a special tool for lifting and hoisting, which has high strength, wear resistance, and safety, and is suitable for a variety of lifting scenarios.

[0003] To address this, patent CN204780431U discloses a double-ended buckle sling, comprising a sling body mainly composed of two stacked flat main straps. Each flat main strap consists of 2 to N layers of synthetic fiber long base straps stacked together. Lifting rings are provided at both ends of the sling body, and several flexible ankylosis protrusions are evenly distributed on both sides of each flat main strap. This double-ended buckle sling is lightweight, flexible, highly wear-resistant, safe, and reliable, and can be widely used in material handling machinery for lifting, traction, tensioning, and load-bearing operations.

[0004] The double-ended slings described above are not convenient for disassembling the lifting rings during use. The lifting rings and slings are fixedly connected and lack a quick disassembly mechanism. Consequently, when the lifting rings are damaged, it is inconvenient to replace them, thus reducing their practicality. Utility Model Content

[0005] The purpose of this invention is to provide a safety flat buckle sling to solve the problem that existing safety flat buckle slings are not easy to disassemble.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a safety flat buckle type sling, including a main strap and a connecting structure;

[0007] Both ends of the main belt are equipped with eyelets, and both ends of the main belt are fixed with connecting structures. The connecting structures include plug-in seats fixed to both ends of the main belt. The plug-in seats have slots inside. One end of the eyelet is fixed with a plug block inside the slot. A connecting seat is fixed to one side of the plug-in seat. The connecting seat has an internal cavity inside. A threaded rod is installed inside the internal cavity. The plug block outside the threaded rod has a hole inside. A first gear is installed on the outside of the threaded rod inside the internal cavity. A second gear is installed on one side of the first gear. A rotating rod is fixed to one end of the second gear. A guide groove is provided on the bottom side of the threaded rod. A guide block is fixed to the bottom end of the internal cavity inside the guide groove. A through hole is provided on one side of the connecting seat.

[0008] The main belt has an internal reinforcing structure.

[0009] Preferably, one end of the threaded rod extends through one side of the plug-in seat into the interior of the plug-in seat, and the plug and the threaded rod form a locking structure through the plug hole.

[0010] With the above structure, the threaded rod is inserted into the socket to fix the plug block inside the slot during use, thereby realizing the installation and removal of the lifting ring buckle, which facilitates its replacement and improves its practicality during use.

[0011] Preferably, the first gear has an internal thread that matches the outer side of the threaded rod, the first gear is threadedly connected to the threaded rod, and the first gear is meshed with the second gear.

[0012] With the above structure, during use, the second gear drives the first gear to rotate, causing the threaded rod to move inside the first gear under the action of the threaded connection. This allows the threaded rod to extend into or move out of the insertion hole, thus facilitating the fixing or disassembly of the insertion block.

[0013] Preferably, one end of the rotating rod extends through one side of the built-in cavity to the outside of the connecting seat and is fixed with a rotating block, and the threaded rod and the guide block are slidably connected through the guide groove.

[0014] With the above structure, the threaded rod is guided by the guide groove and guide block during use, so that the threaded rod can move horizontally and avoid rotation.

[0015] Preferably, the reinforcing structure includes an elastic band disposed inside the main strap, a wrapping layer fixed to the outside of the elastic band, a reinforcing layer fixed to the outside of the wrapping layer, a flame-retardant layer disposed to the outside of the reinforcing layer, a wear-resistant layer disposed to the outside of the flame-retardant layer, protrusions fixed to the outside of the main strap, and an anti-slip pad fixed to one side inside the hanging ring buckle.

[0016] Preferably, the reinforcing layer is a multi-layer woven structure made of polyester fiber, the flame retardant layer is a phosphorus-based flame retardant, and the wear-resistant layer is a polyurethane coating.

[0017] Through the above structure, the overall strength of the main belt is enhanced by the reinforcing layer during use, resulting in better wear resistance. The flame-retardant layer effectively isolates heat and flames, slowing down the spread of fire. The wear-resistant layer further improves the wear resistance of the main belt, thereby protecting the surface of the main belt and extending its service life.

[0018] Preferably, both the protrusions and the anti-slip pad are made of rubber, and the protrusions are distributed at equal intervals on both sides of the main belt.

[0019] With the above structure, the protrusions and anti-slip pads can increase the friction between the object and the device during use, thereby effectively preventing the object from slipping.

[0020] The advantages of the safety flat buckle type sling provided by this utility model are as follows:

[0021] By incorporating a connecting structure, the insert block is inserted into the slot, and then the rotating rod is rotated to insert the threaded rod into the insertion hole, thus fixing the insert block inside the slot. This facilitates the installation and removal of the lifting ring buckle, making it easy to replace and improving its practicality during use.

[0022] The main belt features a reinforced structure and elastic bands, enhancing its elongation. The multi-layered woven structure of polyester fiber in the reinforcing layer provides high strength and excellent abrasion resistance. The phosphorus-based flame retardant layer effectively isolates heat and flames, slowing the spread of fire. The polyurethane coating provides superior abrasion resistance and cut resistance. The inclusion of raised bumps and anti-slip pads, both made of rubber, effectively prevents slippage. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 The present invention provides a safety flat buckle type sling, including a main strap 1 and a connecting structure 3.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, both ends of the main belt 1 are equipped with eyelet buckles 2. Connecting structures 3 are fixed to both ends of the main belt 1. The connecting structure 3 includes a connector 301 fixed to both ends of the main belt 1. A slot 302 is provided inside the connector 301. A plug block 303 is fixed to one end of the eyelet buckle 2 inside the slot 302. A connecting seat 304 is fixed to one side of the connector 301. An internal cavity 305 is provided inside the connecting seat 304. A threaded rod 306 is installed inside the internal cavity 305. An insertion hole 307 is provided inside the plug block 303 outside the threaded rod 306. A first gear 308 is installed outside the threaded rod 306 inside the internal cavity 305. A second gear 309 is installed to one side of the first gear 308. A rotating rod 310 is fixed to one end of the second gear 309. A guide groove 311 is provided on the bottom side of the connector 304. A guide block 312 is fixed at the bottom end of the cavity 305 inside the guide groove 311. A through hole 313 is provided on one side of the connector 304. One end of the threaded rod 306 extends through one side of the plug-in seat 301 and into the interior of the plug-in seat 301. The plug block 303 and the threaded rod 306 form a locking structure through the plug hole 307. The first gear 308 has an internal thread that matches the outer side of the threaded rod 306. The first gear 308 and the threaded rod 306 are threadedly connected. The first gear 308 and the second gear 309 are meshed. One end of the rotating rod 310 extends through one side of the cavity 305 to the outer side of the connector 304 and is fixed with a rotating block. The threaded rod 306 and the guide block 312 are slidably connected through the guide groove 311.

[0032] By inserting the insert 303 into the slot 302, the rotating rod 310 is rotated to drive the second gear 309 to rotate. The second gear 309 meshes with the first gear 308, thereby driving the first gear 308 to rotate. The first gear 308 has an internal thread that matches the outer side of the threaded rod 306, so that the first gear 308 and the threaded rod 306 are threadedly connected. The rotation of the first gear 308 causes the threaded rod 306 to move horizontally under the guidance of the guide groove 311 and the guide block 312, so that the threaded rod 306 is inserted into the insertion hole 307 and the insert 303 is fixed inside the slot 302. This facilitates the installation and removal of the lifting ring buckle 2, making it easy to replace and improving its practicality.

[0033] Reference Figure 2 and Figure 4 As shown, the main belt 1 has a reinforcing structure 4 inside. The reinforcing structure 4 includes an elastic band 401 inside the main belt 1, a wrapping layer 402 fixed to the outside of the elastic band 401, a reinforcing layer 403 fixed to the outside of the wrapping layer 402, a flame-retardant layer 404 outside the reinforcing layer 403, a wear-resistant layer 405 outside the flame-retardant layer 404, and protrusions 406 fixed to the outside of the main belt 1. An anti-slip pad 407 is fixed to one side inside the hanging ring buckle 2. The reinforcing layer 403 is a multi-layer woven structure made of polyester fiber, the flame-retardant layer 404 is a phosphorus-based flame retardant, the wear-resistant layer 405 is a polyurethane coating, and the protrusions 406 and the anti-slip pad 407 are both made of rubber. The protrusions 406 are evenly distributed on both sides of the main belt 1.

[0034] By incorporating an elastic band 401 inside the main belt 1, the main belt 1 can be stretched, improving its elongation performance. The reinforcing layer 403, made of polyester fiber in a multi-layered woven structure, ensures that if a single filament breaks, its end cannot be pulled out of the webbing, preventing the webbing from unraveling. This design offers high strength and good wear resistance. The flame-retardant layer 404, made of phosphorus-based flame retardant, effectively insulates against heat and flames, slowing the spread of fire. The wear-resistant layer 405, a polyurethane coating, provides excellent wear resistance and cut resistance, protecting the surface of the main belt 1 and extending its service life. The inclusion of protrusions 406 and anti-slip pads 407, both made of rubber, increases friction with objects, effectively preventing slippage.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
