Description

Technical Field

[0001] The utility model relates to the technical field of lifting belts, in particular to a synthetic fiber lifting belt with a buckle. Background Art

[0002] Slings are primarily made of polyester synthetic fiber (polyester). The outer layer is protected by a polyester round sleeve, while the inner core is made of a continuous 100% polyester core yarn to bear the lifting load. Synthetic fiber slings are high-performance soft slings made from high-quality, high-strength, low-elongation polyester filaments, representing an alternative to steel wire. They have been widely used in developed industrial countries for over 50 years. Their superior performance is highly valued by users, especially their portability, ease of maintenance, and excellent chemical resistance. Their lightweight, high strength, and resistance to damage to the surface of the hoisted object have made them increasingly popular and are gradually replacing steel wire rope slings in many applications.

[0003] In the application document with publication number CN219792153U, a synthetic fiber lifting belt with a buckle is mentioned. The lifting belt is achieved by placing two sets of U-shaped mounting brackets at both ends of the lifting belt, and passing the screw A through the upper mounting hole A, the lifting belt and the lower mounting hole A in sequence, and then locking it with the locking nut A in a threaded connection, so as to achieve the installation of the U-shaped mounting bracket on the lifting belt. Similarly, the locking nut A can be removed to remove the U-shaped mounting bracket, and a T-shaped turntable is provided on the outer wall of one side of the mounting plate on the buckle mechanism, and the T-shaped turntable is installed inside the bearing on the U-shaped mounting bracket, so that the bearing can install and fix the T-shaped turntable without affecting the T-shaped The turntable rotates, a T-shaped limit plate is set on one side of the T-shaped turntable, and the T-shaped limit plate is set inside the U-shaped mounting bracket, so that the T-shaped limit plate prevents the mounting plate from falling off. The lifting ring buckle is installed on the mounting plate, and the lifting ring buckle is matched with the T-shaped turntable and the T-shaped limit plate, so that the lifting ring buckle can be rotated on the U-shaped mounting bracket. The T-shaped limit plate further prevents the lifting ring buckle from falling off to prevent the lifting ring buckle from falling off the U-shaped mounting bracket during use. The two sets of screw rods B are inserted into the mounting holes B on the mounting plate in a sliding manner, so that the screw B can slide left and right on the mounting plate. The locking nut B is set on the outer wall of the screw B in a threaded connection manner. A pressure plate is set at one end of the screw rod B, so that the pressure plate and the locking nut B limit the screw rod B to prevent the screw rod B from detaching from the mounting plate. A spring is set on the outer wall of the screw rod B, and the spring has an elastic tightening effect, so that the spring keeps the pressure plate in a tight state. A rubber pad is set on the surface of the pressure plate, and the rubber pad has an anti-slip effect, so that the pressure plate in the tight state is in close contact with the surface of the U-shaped mounting frame with the rubber pad, so as to reduce the flexibility of the rotation of the lifting eye buckle. The lifting eye buckle is used in combination with the T-shaped turntable and the T-shaped limit plate to have a rotation and anti-slip effect, which effectively avoids the situation where the lifting belt is not torsioned by the lifting eye buckle, and also avoids the lifting eye buckle and the lifting belt from being twisted. The detachment occurred during the lifting process, which effectively realized the installation of the buckle on the synthetic fiber lifting belt, and also improved the safety and effect of the synthetic fiber lifting belt with the buckle during use. However, there are still certain defects that need to be optimized. The specific defects are as follows: Although the stitching cloth in the lifting belt can enhance the structural strength of the lifting belt, its durability and tightness are limited. Long-term use and frequent load changes may cause the risk of wear, looseness or even breakage at the stitching, thereby affecting the safety and stability of the lifting operation. At the same time, due to the limitation of the stitching cloth, the length of the lifting belt is fixed, and it cannot be flexibly adjusted according to the requirements of different lifting tasks.

[0004] Therefore, it is particularly important to design a synthetic fiber lifting belt with a buckle to change the above-mentioned technical defects and improve overall practicality. Utility Model Content
