Description

Technical Field

[0001] The utility model belongs to the field of slings, and specifically relates to a sling for heat treatment. Background Art

[0003] The Chinese patent with publication number CN220264890U discloses a heat treatment sling, which relates to the technical field of slings. The heat treatment sling includes a shell, a cylinder, a hook, a clamping mechanism and an angle positioning assembly, the top of the shell is fixedly installed with a connecting column, the number of cylinders is two groups and they are arranged on the shell in a left-right distribution state, the bottom of the shell and the cylinder are fixedly installed with a connecting block, the bottom of the connecting block is fixedly installed with a circular shell, the bottom of the circular shell is provided with a cylindrical rod, the hook is fixedly installed at the bottom of the cylindrical rod, the clamping mechanism is arranged on the shell, and the angle positioning assembly is arranged on the cylindrical rod. The heat treatment hanger is convenient for adjusting the distance between the side hooks and the middle hook, so that it can make applicability adjustments according to the size of the workpiece being heat treated, and can also control the angle of the workpiece hanging. The two means effectively prevent the workpieces from contacting each other, avoid the phenomenon of poor heat treatment effect caused by workpiece contact, and ensure the quality of heat treatment. However, the heat treatment hanger in this application, when the workpiece still fits and the hook needs to be rotated, it is necessary to lift the hook with the workpiece hanging on it before the hook can be rotated, which increases the work intensity of the workers.

[0004] In view of this, the present utility model is proposed. Utility Model Content
