2 and 3 are a perspective view and a side view of a grinding apparatus according to an embodiment of the present invention.

Referring to the drawings, one end portion is bent in the other end of the body 200 to which the grinder 300 is coupled, and a plurality of support members coupled to one side of the body 200 to support the body 200 ( 400).

The body 200 is a member for flowing the compressed air flowing from the outside.

This, the body 200 is manufactured as a hollow tube so that the compressed air is introduced into the interior through the inlet pipe 210 from the outside in a curved state.

In addition, the inlet pipe 210 of the body 200 is provided with an air valve 250 for controlling the inflow of air to control the operation of the grinding device 100.

Here, the body 200 may be provided with two hollow tubes 220a and 220b having different diameters, and the two hollow tubes 220a and 220b are inserted into and coupled to each other in a deeply inserted state. The length of the body 200 is adjusted accordingly, and the through hole 230 is formed at one side of the hollow tube 220b to be extrapolated.

In addition, a fixing lever 240 having a screw thread formed at one end thereof is screwed into the through hole 230, and the hollow tube 220a inserted by the rotation coupling of the fixing lever 240 is pressed to a predetermined length state. In the body 200 to be fixed.

In addition, the outer side of the body 200 is provided with a handle 260 that can be moved by the screw rotation to facilitate the gripping of the grinding device 100 according to the working environment.

The grinder 300 is a device for grinding by rotating the grinding plate 310 receives the compressed air.

Such, the grinder 300 is provided with an air hose 320 in communication with the inside of the body 200 on one side in a state coupled to one end of the body 200, the compression introduced into the body 200 Air is introduced into the grinder 300.

That is, when compressed air is introduced into the body 200, the grinder 300 is rotated through the air hose 320, and the grinding plate 310 is rotated by air pressure, thereby grinding the protrusion or the bottom surface. .

The grinder 300 is bolted to the body 200 by a plurality of bolts so as to be detachable from the body 200, and the weight grinder 330 may be coupled to one end of the grinder 300.

In addition, the grinding plate 310 may be coupled to the disk sandpaper to grind rough protrusions or surfaces, and may be used for cleaning walls or floors by combining materials such as scouring pads and sponges.

The support member 400 is a member that is coupled to one side of the body 200 to facilitate the transfer while supporting the body 200.

This, the support member 400 is provided with a driving wheel 410 at one end to adjust the grinding angle of the grinder 300, and to facilitate the transfer in a state in which the body 200 is supported.

In addition, the support member 400 is a pair of support shafts (420a, 420b) having a different diameter is inserted into each other, the height of the body 200 can be adjusted according to the insertion coupling degree.

In addition, a fastening hole 430 is formed on an outer circumferential surface of the support shaft 420b to be extrapolated among the pair of support shafts 420a and 420b, and a bolt-shaped fixing member 440 is inserted into and coupled to the fastening hole 430. do.

Here, when the fixing member 440 is rotated, the fixing member 440 presses the interpolated support shaft 420a to fix the supporting member 400 in a predetermined length state.

In addition, the outer circumferential portion of the support member 400 may be provided with a spring 450 so that the driving wheel 410 is buffered between the transfer, and facilitates the transfer on the wall or bottom surface is uneven surface.

As such, the operation of the grinding apparatus 100 according to an exemplary embodiment of the present invention will be described with reference to FIGS. 2 and 3.

First, in the state in which the worker grips the handle 260 with one hand and the curved one end of the body with the other hand, the compressed air flows from the outside into the body by the control of the air valve 250 so that the grinder When the 300 is introduced, the grinding plate 310 is rotated.

Here, in order to narrow or widen the working radius of the worker, the fixing lever 240 is reversely rotated so that the two hollow tubes 220a and 220b are freely inserted and coupled to the body to fit the working radius of the worker. After adjusting the length of the 200, the fixing lever 240 is rotated to firmly fix the body 200.

In addition, when the grinding angle of the grinder is to be adjusted, the fixing member 430 of the support member 400 is reversely rotated so that the pair of support shafts 420a and 420b can be freely inserted into the grinding angle. After the adjustment, the fixing member 430 is rotated to firmly fix the supporting member 400.

Accordingly, the grinding device 100 adjusts the length of the body 200 according to the working environment, or adjusts the height of the support member 400 so as to grind and clean the wall or bottom surface out of reach of the operator. Can be used for work.

As such, the grinding device 100 allows the grinding work of the wall surface which is out of reach by adjusting the length of the body 200 according to the working environment, and in the case of the floor work, the standing work is performed and thus the work efficiency is improved. This can improve productivity.

In addition, the grinding angle is adjusted by adjusting the height of the support member 400, and the driving wheel 410 facilitates the transfer, so that uniform grinding is possible even at a curved place or a place having irregularities.

As described above, the grinding apparatus according to the present invention provides the following effects.

First, in the state where the grinder is coupled to the body, the length of the body is adjusted according to the working environment so that the grinding work can be carried out to the part where the operator can't reach it. Compared to the above, it can improve work efficiency.

Second, the grinder is adjusted by the support member grinding height and angle and easy to transfer by the driving wheel can always grind the work surface uniformly and clean regardless of the working environment.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Various modifications and variations are possible, of course, within the equivalent scope of the utility model registration claims to be described.
