Lifting tool with protective lock catch

Abstract

The invention discloses a lifting tool with a protective lock catch. The lifting tool comprises a lifting ring and a lock. Connecting holes are welded to the bottom face of the lifting ring, and a connecting part is connected between the connecting holes through connecting bolts. The lifting tool is provided with a closed ring and the lock, the closed ring can rotate along a rotary shaft and is inserted into the lock, an elastic piece pushes a locking device to pop up through the elasticity of the elastic piece, sawteeth and the locking device are mutually locked, the lifting ring is in a closed shape, and therefore it is avoided that in the lifting process, the risk is caused by shake disengagement of objects; and a manual rotary knob is arranged on the surface of the lock and connected with a rotatable switching part, the switching part rotates to extrude one end of the locking device, the locking device rotates along a rotary shaft of the locking device, the locking device is separated from the sawteeth, the closed ring can be rotated out, thus, the lifting tool is opened, goods are unloaded, the lifting tool is convenient to use and easy to operate and use, and convenience is improved while safety is improved.

Description

technical field [0001] The invention relates to the technical field of slings, in particular to a sling with a protective lock. Background technique [0002] Spreader refers to the device for lifting heavy objects in hoisting machinery. The most commonly used spreaders for lifting items are hooks and slings. Others include lifting rings, lifting suction cups, clamps and forks, etc., which are widely used Used in the lifting industry. [0003] The current spreader often has a rotatable shaft on the top to adjust the angle, but a single shaft cannot adjust the center of gravity and angle sensitively, resulting in the center of gravity often shifting during hoisting. The traditional spreader does not have protection Due to the lock structure, the traditional spreader cannot be closed, and the sliding hook is prone to occur, which is very dangerous. To solve the above problems, a spreader with a protective lock is specially proposed. Contents of the invention [0004] The pu...

[0003] The current spreader often has a rotatable shaft on the top to adjust the angle, but a single shaft cannot adjust the center of gravity and angle sensitively, resulting in the center of gravity often shifting during hoisting. The traditional spreader does not have protection Due to the lock structure, the traditional spreader cannot be closed, and the sliding hook is prone to appear, which is very dangerous. In view of the above problems, a spreader with a protective lock is proposed.
