Description

[Detailed explanation of the idea] The present invention relates to a leveler.

The conventional leveler of this type is as shown in Fig. 1.
The device includes a shaft 1 having a male screw 1a screwed into a female screw 6 provided at the bottom of a housing 4 of the device, and a pedestal 2 rotatably provided at the lower end of the shaft 1. will be installed. To adjust the height of the leveler with this structure, use a spanner to rotate the hexagonal flange 3 fixed to the lower end of the shaft 1, or insert the shaft of a screwdriver into the through hole 7 provided in the shaft 1. Operations such as inserting and rotating are performed.

The device having such a housing 4 is equipped with casters (not shown) to facilitate movement and transportation.
However, the leveler is recessed into the upper part of the device's housing 4 so as not to cause any hindrance when moving or transporting the device.
After the pedestal 2 is extended to a position where it makes contact with the pedestal 2, the height is adjusted so that the installation height of the device becomes a predetermined height.

However, such levelers are located at least in the four corners of the bottom of the equipment, and must be moved up and down each time the equipment is moved between processes such as loading and unloading, assembly, adjustment, and inspection. Since this operation is performed manually, it has drawbacks such as requiring a large amount of man-hours.

An object of the present invention is to provide a leveler that allows raising and lowering operations using an electric tool, solves the above-mentioned drawbacks, and improves workability.

The present invention provides a leveler equipped with a threaded part that is screwed into a housing to adjust the height of the housing, in which a groove or a square hole is provided at the upper end of a shaft having the threaded part. The leveler features:

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a sectional view showing a leveler according to an embodiment of the present invention. In FIG. 2, the pedestal 2 and shaft 1 are in a state where the device is supported, that is, installed on the floor 5, and the pedestal 2' and shaft 1' are in a state where they are recessed into the inside of the casing 4 of the device. show. This leveler is the same as a conventional leveler in that it includes a shaft 1 having a hexagonal flange 3 at one end and a thread 1a on the shaft, and a rotatable pedestal 2 at the lower end of the shaft 1. However, in this embodiment, a square hole 8 is further provided at the upper end of the shaft 1, and the leveler can be easily raised and lowered by using an electric rotary tool that fits this square hole 8. I can do it. Taking lowering as an example, until the pedestal 2 is installed on the floor 5, use the tool mentioned above (rough adjustment), and to finely adjust the height of the device, use the hexagonal flange with a wrench, etc., as in the past. You can do this by rotating it.

Note that the same effect can be obtained even if the square hole 8 has a groove structure.

According to the present invention, as described above, by providing a square hole or a groove in the upper end of the shaft, it is possible to use a power tool and improve workability.
