DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height-adjusting nut to be mounted on a bottom plate of a housing device such as a freezer, a refrigerator, a vending machine, or various devices such as a retractable security box, and a structure for mounting the nut to the bottom plate. The height of the bottom plate can be adjusted by adjusting the screwing amount of the bolt screwed into the height adjusting nut, thereby adjusting the length of the bolt projecting from the height adjusting nut.

[0002]

2. Description of the Related Art Devices such as freezers, refrigerators and vending machines are installed not only indoors but also outdoors, and may be installed in places with steps. In this case, to adjust the height of the device horizontally, usually as shown in FIG.
Height adjustment nuts B are attached to the four corners of the bottom surface of the bottom plate A, and the amount of protrusion (height) of the bolt C from the nut B is adjusted by adjusting the screwing amount of the bolt C screwed into the nut B. The equipment installed on the ground or the like is horizontal.

Normally, the bottom plate A is composed of an upper bottom plate D and a lower bottom plate E arranged thereunder, as shown in FIG. As shown in FIG. 8 (a), the height adjusting nut B attached to the upper insertion portion I can be inserted into the upper through hole H of the upper bottom plate D at the upper end of the cylindrical portion G having a screw hole F therein. Is formed on the upper surface of the cylindrical portion G, and a main body flange J for supporting the upper bottom plate D is formed.
A circular lower bottom plate flange L having a larger diameter than the lower through hole K is formed.

In order to mount the height adjusting nut B to the bottom plate A, conventionally, a cylindrical portion G and an upper insertion portion I of the nut B are inserted through a lower through hole K of the lower bottom plate E, so that an upper 8B is inserted into the upper through hole H of the upper bottom plate D.
The nut B is in contact with the bottom surface of the lower bottom plate E as shown in FIG.
An arbitrary number X of the outer peripheral edge of the lower bottom plate flange L is welded to the bottom surface of the lower bottom plate E, and the height adjustment nut B is fixed to the bottom plate A.

[0005]

The conventional height adjusting nut and its mounting structure have the following problems. . Since the height adjusting nut B cannot be fixed to the bottom plate A unless the lower bottom plate flange L of the nut B is welded to the bottom plate A due to its structure, welding work is essential. However, when welding, sparks (spatter) at the time of welding are scattered, enter the screw hole F of the height adjusting nut B and weld to the screw, and the spatter hinders the screwing of the bolt into the screw hole. May not be possible. . Conventionally, in order to prevent the invasion of spatter into the screw hole F, a protective cap was put on the entrance of the screw hole F for welding, and the protective cap was removed after the welding was completed.
For this reason, welding work was troublesome and work efficiency was poor. Also, the removed protective cap was sometimes lost. . Since the height adjustment nut B is simply welded to the bottom plate A, the height adjustment nut B may fall from the bottom plate A when an external impact is applied or an excessive force is applied. . Since the welding operation is expensive, the cost is high. . The labor burden of the worker is large due to the welding work,
The efficiency of attaching the height adjusting nut B to the bottom plate A is low, which contributes to high cost.

[0006]
