Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a leveling device for a main body of an appliance such as an oil burner.

As shown in Fig. 1, the conventional leveling device uses a bolt 2 screwed into the bottom of the instrument body 1, but since its head 3 is protected by a cover 4 made of rubber or resin, the instrument body It was difficult to make fine adjustments after the main body 1 was set up, and additionally, separate metal fittings had to be used to secure the main body 1.

The present invention has been developed to eliminate the above-mentioned drawbacks.

An embodiment of the present invention will be described below with reference to FIGS. 2-3.

In the figure, reference numeral 5 denotes a main body of a hot-air type oil burner or the like, and screw holes 6, 6, . . . are provided at the four corners of the bottom surface.

Reference numeral 7 denotes an integrally molded adjustment bolt, which includes a threaded portion 8 at the tip, a stepped portion 9, a hexagonal head 10, and a round bar-shaped protrusion 11 protruding from the head 10.

The adjusting bolt 7 is screwed into the screw hole 6 with its threaded portion 8, as shown in FIG.

Reference numeral 12 denotes a fixing fitting for fixing the main body 5 to the floor surface 13 via the adjustment bolt 7, which has threaded holes 15 and 15 for the anchor bolts 14 on both sides, and has screw holes 15 and 15 for the anchor bolts 14 inside thereof. The insertion hole 16 corresponds to the insertion hole 6.6.
．． 16 are formed.

This insertion hole 16.16 bulges out a part of the fixing fitting 12 in the shape of a truncated cone, and is bored in the ceiling surface.

Therefore, when the protrusion 11 of the adjustment bolt 7 is inserted into the insertion hole 16, the tip of the protrusion 11 does not come into contact with the floor surface 13.

Numeral 17 is a well-known bushing nut that is press-fitted into the protrusion 11 to prevent the protrusion 11 from being removed.

When the adjustment bolt 7 is screwed into the main body 5, it can be done by rotating the head 10 with a spanner or the like, as with conventional bolts.

Here, the fixing fitting 12 is inserted into the protrusion 11 through the insertion hole 16, and the bushing nut 17 is further press-fitted to complete the assembly.

In this state, the main body 1 can be fixed to the floor 13 by standing the main body 5 on a predetermined floor 13 and screwing the anchor bolt 14 into the floor 13 through the screw hole 15.

A level (not shown) attached to the instrument body 5 here
Turn the adjustment bolt 7 with a spanner while watching the main body 5.
By moving the square up and down, the main body 5 can be installed horizontally.

f) %, before fixing the main body 5 with the anchor bolt 14,
Adjust the height and get C.

In addition, the bush nut 17 weighs approximately 180 kg when the diameter d of the protruding portion 11 is 8 mm, and approximately 320 kg when the diameter d of the protruding portion 11 is 10 mm.
Since it can withstand the slat load of 3 to 4 pieces, it seems that 3 to 4 pieces are sufficient to withstand external forces acting on this type of equipment.

As described above, the leveling device of the present invention has the advantage that the height can be easily adjusted even after the device body is installed, and its assembly is extremely simple.

Claims (1)

[Claims for Utility Model Registration] An adjustment bolt is provided which has a threaded part formed on one side of the head via a stepped part and a protrusion formed on the other side of the head, and the adjustment bolt is connected to the above-mentioned screw. The adjusting bolt is screwed into a predetermined position on the bottom of the instrument main body with the holding part, and the fixing metal fitting is inserted into the protruding part of the adjustment bolt through the insertion hole, and a bushing nut is press-fitted. Equipment leveling device.
