The invention provides a quick-adjustable sling. The quick-adjustable sling comprises two L-shaped brackets connected by an intermediate support structure, two hooks and a supporting plate, wherein included angles of the L-shaped brackets are respectively connected with two ends of the intermediate support structure by hinges, openings of the L-shaped brackets face outward, one ends of the hooks are hooked on one ends of the L-shaped brackets, the other ends of the hooks are connected with lifting rings, the hooks correspond to the L-shaped brackets one-to-one, the supporting plate is connected with the other ends of the L-shaped brackets through the hinges, and a rubber pad is fixedly arranged on a plate surface, facing outwards, of the supporting plate. According to the technical schemeof the quick-adjustable sling, a hinged four-bars mechanism principle is used, the supporting plate and the rubber pad firmly support the inner wall of a crucible, the greater the gravity, the greaterthe supporting force, the reliability is high, the width of the sling can be adjusted, the quick-adjustable sling can adapt to a variety of crucibles of different specifications, and the applicability is high.
本发明提供了一种快速调节式吊具,包括:通过中间支撑结构相连接的两个L型支架,所述L型支架的夹角处分别与所述中间支撑结构的两端通过铰链相连,所述L型支架的开口朝外;两个吊钩,所述吊钩的一端钩挂在所述L型支架的一端,所述吊钩的另一端连接于吊环上,所述吊钩与所述L型支架一一对应;支撑板,与所述L型支架的另一端通过铰链相连,所述支撑板朝外的板面上固定设置有胶皮垫。通过本发明的技术方案,利用铰链四杆机构原理,使得支撑板和胶皮垫牢牢撑住坩埚内壁,而且重力越大,撑力越大,可靠性强,吊具的宽度大小可调节,同一个快速调节式吊具能够适应多种不同规格的坩埚,适用性强。
