Description

[Detailed description of the invention] The invention relates to a pipe mounting structure used, for example, when installing decorative pipes on both sides of the front opening of an audio rack, so that the installation can be easily performed and the appearance can be made beautiful. It is something.

Conventionally, when installing this type of pipe, a hole is made in the mounting board and the end of the pipe is inserted directly into the hole, or if the mounting board is made of metal, it is welded, or a cylindrical pipe is pre-installed on the mounting board. A shaped receiver is provided in which the end of the pipe is inserted,
It was fixed with screws as necessary.

However, if welded pipes are fixed with screws, the installation process is time consuming and the appearance is very unsightly.Also, simply inserting the pipe into a hole in the mounting board or a receiver provided on the mounting board does not require much external force. I had a problem with the pipe coming off.

The present invention solves these conventional problems and provides a pipe mounting device that is easy to install and has an excellent appearance.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 and 1 are mounting boards arranged at positions facing each other, 2 is a disc-shaped base 2a,
A fixing device integrally formed with a through hole 2b for screw insertion and a hook-shaped engagement piece 2c protruding from the periphery of the base 2a in the radial direction of the base 2a, 3 is a pipe, 3a is a pipe 3. A notch formed on the end face, 3b an arm provided at the lower end, 3c a through hole formed at the lower end, 4 a decorative ring integrally molded with resin, 4a
4b is a flexible pressing piece formed on the inner surface of the center hole 4a, and 5 is a screw. The base 2a of the fixture 2 is set to have a diameter that is approximately the same as or slightly smaller than the inner diameter of the pipe 3, and the center hole 4a of the decorative ring 4 is set to have a diameter that is the same as or slightly larger than the outer diameter of the pipe 3. The inner diameter of the pressing piece 4b is set to be slightly smaller than the outer diameter of the pipe 3. Further, the arm portion 3b of the pipe 3 is formed in a straight line as shown in FIG.
The amount of depression l from the virtual line 3' of the perfect circle is set to be approximately the same as the thickness of the arm portion 2c' of the engaging piece 2c.

In the above structure, first, as shown in FIG. 3, the base 2a of the fixture 2 is attached to the mounting board 1 using screws 5 inserted into the through holes 2b of the fixture 2. The decorative ring 4 is fitted onto the pipe 3 in advance, and the end of the pipe 3 is moved as shown by arrow A in FIGS. While fitting into the stand 2a, the tip of the engaging piece 2c is engaged with the through hole 3c of the pipe 3. Finally, when the decorative ring 4 is moved in the direction of arrow B in FIG. 3 and its end surface is brought into contact with the mounting board 1, the pressing piece 4b engages the outer periphery of the pipe 3 and the fixture 2, as shown in FIG. By tightening the coupling piece 2c, the pipe 3 can be fixed to the fixture 2 without wobbling. Of course, since the tip of the engaging piece 2c of the pipe 3 is engaged with the through hole 3c, it will not come off even if an external force is applied. Moreover, since the end of the pipe 3 and the fixture 2 are completely covered by the decorative ring 4, the appearance is also extremely beautiful.

In addition, as in this embodiment, the arm portion 3b of the pipe 3
If the perfect circle of the pipe 3 is slightly concave so that the outer periphery of the pipe 3 and the outer surface of the engaging piece 2c are flush with each other even when the engaging piece 2c of the fixture 2 is engaged, This is advantageous because the decorative ring 4 can be moved extremely smoothly in the direction of arrow B in FIG. Furthermore, in the case of fixing both ends of the pipe 3 as shown in FIG. 1, it goes without saying that the above-mentioned series of attachment operations can be performed at both ends of the pipe 3 at the same time. At this time, the engagement operation of the pipe 3 in the direction of the arrow A in FIGS. 3 and 4 can generally be performed easily enough by providing a slight margin in the dimensions between each component.

As described above, according to the present invention, the pipe can be prevented from rattling by simply engaging the through hole of the pipe with the engaging piece of the fixture and fitting the decorative ring to cover the pipe and the fixture. Since it can be installed without coming off, pipe installation work is extremely easy.
Moreover, an excellent effect of making the appearance beautiful can be obtained.
