Description

Technical Field

[0001] This utility model relates to the technical field of lifting sling accessories, and more specifically, to an anti-wear connecting buckle for a friction-resistant and anti-aging composite lifting sling. Background Technology

[0002] Friction-resistant and anti-aging composite lifting slings are a special type of lifting equipment that combines multiple materials and structural designs. By optimizing material combinations and protective designs, they enhance wear resistance and resistance to environmental aging. Connecting buckles are connectors used in conjunction with the lifting slings to connect the slings to hooks and other lifting devices.

[0003] The standard connector consists of a U-shaped ring (made of high-strength alloy steel) and a detachable connecting post. It adopts two assembly modes: one is the nut locking type, where the connecting post is inserted into the through holes at both ends of the U-shaped ring and then fixed by applying pre-tightening force through the anti-loosening nut; the other is the threaded direct connection type, where the U-shaped ring has a built-in threaded hole on one side, which directly engages with the external thread of the connecting post for fastening. The surface treatment adopts a hot-dip galvanizing + epoxy resin coating process to enhance the surface hardness and corrosion resistance.

[0004] When existing connectors are used in work environments with high levels of dust, metal shavings, or other particulate matter, insufficient sealing design can lead to foreign objects intruding into the threaded pair or nut gap. The accumulation of dust particles increases the friction between the connector and the nut or threaded hole, making it difficult to disassemble the connector. Utility Model Content

[0005] The purpose of this utility model is to address the problem that dust can enter the nut or threaded hole during the use of current connectors, increasing the friction between the connector and the nut or threaded hole, making it difficult to disassemble the connector.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A wear-resistant connector buckle for a friction-resistant and anti-aging composite lifting sling is provided to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A wear-resistant connecting buckle for a friction-resistant and anti-aging composite lifting sling includes a ring buckle, a connecting block one fixed to one end of the ring buckle, and a connecting block two fixed to the other end of the ring buckle. The connecting block one has a threaded hole, and the connecting block two has a connecting hole. A connecting post is provided between the connecting block one and the connecting block two, the connecting post passing through the connecting hole and being threadedly connected to the threaded hole. A plug is fixed to the end of the connecting post near the connecting block two, and a locking nut is threadedly connected to the end of the connecting post near the connecting block one. A dustproof structure is provided between the locking nut and the connecting block one. The dustproof structure includes an insert ring fixed to the side of the locking nut, and a dustproof ring, which is an elastic rubber ring, is fixed to the side of the insert ring away from the locking nut. A slot is provided on the side of the connecting block one near the locking nut, and the insert ring and the dustproof ring slide into the slot, with the dustproof ring fitting against the bottom of the slot.

[0010] As a preferred technical solution of this application, a mounting ring is fixed on the side of the connecting block away from the locking nut, and a dustproof pad is fixed inside the mounting ring. The dustproof pad is in contact with the connecting column and is an elastic rubber pad.

[0011] As a preferred technical solution of this application, a barrier brush is fixed inside the mounting ring, the barrier brush is in contact with the connecting post, and the barrier brush is a flexible brush.

[0012] As a preferred technical solution of this application, an oil supply channel is provided on the side of the connecting block near the locking nut, an oil injection pipe is fixed on the side of the connecting block near the locking nut, a guide channel is provided at the end of the oil supply channel away from the oil injection pipe, the guide channel is connected to a diversion channel, and the diversion channel is connected to the connecting hole.

[0013] As a preferred technical solution of this application, the oil injection pipe has a sealing plug inside the threaded connection, and a rubber sealing plug is fixed at one end of the sealing plug that extends into the oil injection pipe.

[0014] As a preferred technical solution of this application, a rubber strip is fixed to the end of the rubber sealing plug away from the sealing plug, and the end of the rubber strip away from the sealing plug extends into the oil delivery channel and is fixedly connected to the connecting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] When connecting the locking nut to the connecting post, as the locking nut is turned, the insertion ring, carrying the dustproof ring, enters the slot. After the locking nut is tightened, the dustproof ring fits against the bottom of the slot, achieving dust prevention and reducing the entry of dust. At the same time, the dustproof pad reduces the entry of dust into the threaded groove, and the barrier brush prevents dust from sticking to the dustproof pad, further reducing the entry of dust and reducing the phenomenon that the connecting post is difficult to unscrew due to dust.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figure 1-6 As shown, this embodiment proposes an anti-wear connecting buckle for a friction-resistant and anti-aging composite lifting sling, including a ring buckle 1. One end of the ring buckle 1 is fixed with a connecting block 2, and the other end of the ring buckle 1 is fixed with a connecting block 3. The connecting block 2 has a threaded hole 20, and the connecting block 3 has a connecting hole 4. A connecting post 5 is provided between the connecting block 2 and the connecting block 3. The connecting post 5 passes through the connecting hole 4 and is threadedly connected to the threaded hole 20. A plug is fixed at the end of the connecting post 5 near the connecting block 3. A locking nut 6 is threadedly connected at the end of the connecting post 5 near the connecting block 2. A dustproof structure is provided between the locking nut 6 and the connecting block 2. The dustproof structure includes an insert ring 7 fixed to the side of the locking nut 6. A dustproof ring 8 is fixed on the side of the insert ring 7 away from the locking nut 6. The dustproof ring 8 is an elastic rubber ring. A slot 9 is provided on the side of the connecting block 2 near the locking nut 6. The insert ring 7 and the dustproof ring 8 slide into the slot 9, and the dustproof ring 8 fits against the bottom of the slot 9.

[0030] A mounting ring 10 is fixed on the side of the connecting block 12 away from the locking nut 6. A dustproof pad 11 is fixed inside the mounting ring 10. The dustproof pad 11 fits against the connecting post 5. The dustproof pad 11 is an elastic rubber pad.

[0031] A barrier brush 12 is fixed inside the mounting ring 10. The barrier brush 12 is in contact with the connecting post 5. The barrier brush 12 is a flexible brush.

[0032] When the locking nut 6 is connected to the connecting post 5, as the locking nut 6 is tightened, the insertion ring carrying the dustproof ring 8 enters the slot 9. After the locking nut 6 is tightened, the dustproof ring 8 fits against the bottom of the slot 9 to prevent dust from entering. At the same time, the dustproof pad 11 can reduce the entry of dust into the threaded groove, and the barrier brush 12 can reduce the adhesion of dust to the dustproof pad 11, further reducing the entry of dust.

[0033] An oil supply channel 13 is provided on the side of the connecting block 12 near the locking nut 6. An oil injection pipe 14 is fixed on the side of the connecting block 12 near the locking nut 6. A guide channel 15 is provided at the end of the oil supply channel 13 away from the oil injection pipe 14. The guide channel 15 is connected to a diversion channel 16, and the diversion channel 16 is connected to the connecting hole 4.

[0034] The oil injection pipe 14 has a threaded connection to a sealing plug 17, and a rubber sealing plug 18 is fixed to one end of the sealing plug 17 that extends into the oil injection pipe 14.

[0035] A rubber strip 19 is fixed to the end of the rubber sealing plug 18 away from the sealing plug 17. The end of the rubber strip 19 away from the sealing plug extends into the oil delivery channel 13 and is fixedly connected to the connecting block 12.

[0036] When the connecting post 5 is inconvenient to remove, unscrew the sealing plug 17 and add lubricating oil into the oil supply channel 13 through the oil injection pipe 14. The lubricating oil flows into the guide channel 15 along the oil supply channel 13, and finally flows into the threaded hole 20 and the connecting post 5 through the diversion channel 16. This facilitates lubrication between the connecting post 5 and the threaded hole 20, and makes it easier to disassemble the connecting post 5. After unscrewing the sealing plug 17, the rubber strip 19 can be protected from being lost due to careless placement of the sealing plug 17.

[0037] In this application, the lifting sling is connected to the ring buckle 1, and then the connecting post 5 is inserted into the connecting hole 4 and extends into the threaded hole 20. The connecting post 5 is then tightened to pass through the threaded hole 20. Next, the locking nut 6 is connected to the connecting post 5 to further tighten it. As the locking nut 6 is tightened, the insert ring carrying the dustproof ring 8 enters the slot 9. When the locking nut 6 is tightened, the dustproof ring 8 fits against the bottom of the slot 9, achieving dust prevention and reducing dust ingress. Finally, the hook is hung on the connecting post 5 for use with the lifting sling and lifting equipment.

[0038] When disassembling the connecting post 5 after use, if it is difficult to unscrew the connecting post 5, unscrew the sealing plug 17 and add lubricating oil into the oil supply channel 13 through the oil injection pipe 14. The lubricating oil flows into the guide channel 15 along the oil supply channel 13, and finally flows into the threaded hole 20 and the connecting post 5 through the diversion channel 16, which facilitates lubrication between the connecting post 5 and the threaded hole 20 and makes it easier to disassemble the connecting post 5.
