Description

Technical Field

[0001] The utility model belongs to the technical field of cargo clamping structures, and in particular relates to a cargo clamping structure capable of clamping cargo of various shapes. Background Art

[0002] Cargo clamping structures, also known as clamp tongs, are tools specifically used for stone handling, lifting and installation. They have strong clamping force and stable performance, ensuring the safety and efficiency of stone during handling and installation. They are mainly used for clamping and handling marble, asphalt, granite, slate and other stones. In the stone processing, construction and decoration industries, stone clamp tongs can easily cope with the handling and installation needs of various stones, improve work efficiency and reduce labor costs.

[0003] Traditional cargo clamping structures can only hold rectangular cargo, but are unable to stably secure cylindrical cargo of any size. This can lead to unstable clamping, and in severe cases, the object may fall off the structure, causing damage. Therefore, we propose a cargo clamping structure that can hold cargo of various shapes. Utility Model Content

When the user uses the clamp lifting clamp body to clamp cylindrical goods, the clamp lifting clamp body will respectively drive the multiple anti-sliding blocks to clamp the cylindrical goods through the two first clamping plates and the two second clamping plates. The groove and slider ensure that the slider can slide in the first slide groove. The driving component and the one-way threaded rod are set to ensure that the user can drive the two one-way threaded rods to rotate through the driving component, so that the slider is moved by the action of the two first slide groove threads, and the slider drives the second splint to move, so that the user can adjust the distance between the first splint and the second splint according to the diameter of the cylindrical cargo. The fixed component and the first rotating rod are set to ensure that the user can fix the first rotating rod in the rotating block through the fixed component and cannot move, thereby preventing the first rotating rod from rotating due to external influences.
