Description

DETAILED DESCRIPTION OF THE INVENTION The present invention was developed mainly as a hanging tool for iron plate coverings in can manufacturing and press operations, and its features include that it can be easily attached and detached, and that it can be hung diagonally. This invention improved work efficiency and safety.

Figure 3 shows workpiece AB as an example of press work.
At the center of gravity ○ position, press the workpiece to stabilize it during 1st processing, and then lift the hoist F to the center of gravity after bending or point E. Use the teeth of the lever to move the workpiece to the center side. Simply push it into the lever position (angle) as shown in the picture and replace it. Previously, it was necessary to attach and remove a separate type of sling at point A, but this sling and work are no longer necessary.

This product has a C-shaped frame (9) structure with sufficient strength, and a shaft (6) at the top with a center line above and below the tip.
) A cowl (8) is fixed at the bottom with its teeth facing upward. There is a two-pronged fork (10) at the bottom of the shaft, a lever (3) is assembled in the middle with a pin (2), and a plate coil spring (2) is attached to the bottom of the shaft to press the teeth of the lever toward the rear side. 7) and an oblong mortar-shaped hole into which the upper part fits. There is also a matching hole on the top of the lever.

The shaft is constantly pushing up the umbrella-shaped nut with the spring (5) at the top of the frame, but in the case of the 7-yaft, the lever can be pushed down as far as necessary to apply it, and the lever can be pushed down to the left and right until it hits the frame. Rotate about 280 degrees.

The operating principle of the lever is the same as that of conventionally sold levers, but the present invention has two advantages: (1) that the lever angle can be obtained within the working range of the shaft for the required hanging angle, and (1) that angle can be maintained completely. It is. This lifting device has a shaft structure with only an A taper that maintains its angle completely fixed during lifting or hanging.

B shows the uneven shaft structure.

C shows a shaft with a circumscribed spur gear structure.

[D] Shows a shaft structure with knurled grooves on the sheet surface.

E shows a bevel gear-like structure.

Claims (1)

[Scope of Claims] The hanging tool of the present invention has a C-shaped frame, and together with a lever assembled on a shaft extending from the top, an effective rotation angle can be obtained until the lever touches the left and right frames, and the material can be lifted and lifted. The selected angle can be maintained perfectly even when lowering. (A) Due to the tapered structure, the selected angle can be obtained steplessly, and when a load is applied, the angle can be maintained by pressing the tapered part. (B) A lever in which the seat surface of the shaft meshes with unevenness to maintain the lever angle under load.(C) A lever in which the seat surface of the shaft meshes with a circumscribed spur gear structure and an internal spur gear that is opposite to the frame. Something that can maintain the angle. (D) One with a horizontal knurled tooth shape on the shaft seat surface and a contrasting structure on the frame. (E) The shaft seat surface has a bevel gear structure and the frame also has a contrasting structure.
