Description

Technical Field

[0001] The utility model relates to the field of electric hoist devices, and more specifically to a hanging structure of an electric hoist. Background Art

[0002] Electric hoist is a special lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places.

[0003] The existing electric hoist hook structure uses a single hook with multiple pins inserted into the fixed block and the connection block. This method makes the single hook with multiple pins bear a heavier weight of the lifted goods, causing the multiple pins to bend and deform easily, causing safety accidents. At the same time, the power cord is long, and operators with short height need to raise their arms and heads to hold the controller to operate, which is inconvenient. Therefore, it is necessary to improve the existing technology. Utility Model Content

The fixing block is freed and conveniently moves the connecting block downward to remove the hook for replacement. By using a tension spring to pull the lower end of the latch pin close to the inside of the hook, the goods hung inside the hook can be prevented from falling, thereby improving safety. By rotating and tightening the threaded sleeve, the fixing spring and controller can be conveniently installed. The design of the spring and the support hook can lift and pull the power cord, so that the controller is not easily damaged by touching objects on the ground, and the operator can conveniently pull the controller down to a position that suits his height for operation.
