Description

[Detailed description of the invention] The present invention relates to the invention of a rod-shaped body attachment mechanism, which can be accurately clamped onto a rod-shaped body such as an antenna by a simple mechanism and operation in the airframe or other casing. The aim is to obtain a mechanism that can be attached.

It has been common practice to attach rod-shaped bodies such as antennas to the body of automobiles, and to attach other rod materials to the casings of various devices. Even if the antenna is inserted into an insertion hole formed in the car body and tightened with fasteners placed inside and outside the car body, such installation is difficult due to the extremely narrow space in the middle of the rod-like body, which has a considerable length. It is quite difficult to attach the rod-shaped body in one part, and furthermore, fixing the proximal end of the rod-shaped body is extremely important in terms of stabilizing the attachment state, and conventionally, it is difficult to fix the proximal end of the rod-shaped body. is proposed.

However, since these conventional attachment mechanisms consist of a part that clamps the rod-shaped body and a part that fixes to the pace member, most of them are constructed by fully connecting multiple members. As mentioned above, the tightening means requires tightening for holding the rod-shaped body and tightening for fixing the mounting bracket itself to the pace member, so a plurality of tightening bolts and nuts are always required. In any case, the mounting mechanism is complicated and the installation process is complicated.

The present invention was devised through research to eliminate the disadvantages of the conventional products as described above, and the specific embodiment thereof is shown in the attached drawings. In particular, it is shown as a preferred embodiment for fixing the base end of the antenna base tube 10 mounted on the vehicle body, and the ring portion 1 for receiving the rod-shaped body 10 such as the antenna base tube is bent. Parallel bent portions 2, 2 protruding outward are formed at both ends of the plate material formed by extending the bent portions 2. The overlapping part 3 is drawn and bent parallel to each other so as to maintain an appropriate gap.
9, one side of one side 3 extends longer than one side of the other 9, and the entire side of this extended side forms a sloped part 4, and the other side 9 is formed on the inner surface of this sloped part 4. edge 9a of
are joined to each other, and the end edge 9a is attached to the other 9.
A long hole 5 is formed in a direction crossing the ring, and by pressing the overlapping portion 9 into contact with the long hole 5 against one of the overlapping portions 3, the overlapping portion 9 is slid along the inclined portion 4, and the ring A tightening member 7 for tightening the portion 1 is inserted and fastened to a suitable base portion body 8 as shown in FIG.

In this third embodiment, the antenna base tube 10 has an inclined joint part 12 and a receiving fitting 13 as described above.
Therefore, the upper end side of the antenna base cylinder 10, which is a rod-shaped body, is fixed to a steep slope part such as a corner part of the car body, and the antenna element group 11 is expanded and contracted. However, the above-mentioned base body 8 is appropriately set in the vehicle body below such a vehicle body corner, or an appropriate member located as a vehicle component is used as a base. It is clear that it can be selected as part 8.

According to the present invention as described above, it is clear that the mounting mechanism as shown in FIG. 2 is obtained by bending a single plate-like member. By screwing and tightening the joint 7 to the base body 8, the other overlapping part 9, which was initially located at the imaginary line position, is gradually brought closer to the one overlapping part 3, as shown in FIG. There is an overlapping part 9 which is thus close and depressed.
Since the end edge portion 9a is joined to the inner surface of the inclined portion 4, the bent portions 2, 2 in the direction perpendicular thereto are also brought closer together, thereby reducing the diameter of the ring portion 1 and tightening the rod-like body 10. Of course, this mounting bracket can be fixed to the base body 8 by tightening the fastener 7 as described above. Fixation to the base body 8 and rod-like body 10 by tightening operation by
This can be considered a very significant idea in practical terms, since it is possible to simultaneously achieve clamping of the two.

Among these, the device according to the present invention is significant in that it can both secure to the base body and clamp the rod-like body with a single tightener as described above, but because it is a single tightener, the direction of the mounting bracket is different. Of course, if the metal fittings are not fixed, another fastener may be used, or a protrusion or the like may be formed on the base body 8 or the overlapping portion 3 to prevent the metal fittings from rotating. .

Further, although the above-mentioned tightening member 7 is to be screwed into the label 8a of the base body 8, depending on the case, it may be attached using a nut or a nut may be attached to the bottom surface of the base body 8 by welding or the like. .

Furthermore, the fastener 7 shown in the figure is of the split groove type and has a button, that is, it can be operated from above with a screwdriver, but in some cases a square-headed fastener may be used. You can also do that.

[Brief explanation of the drawing]

The drawings show embodiments of the present invention; Fig. 1 is a partially omitted side view showing the case where the mounting mechanism according to the present invention is used for attaching the end of the antenna base tube, and Fig. 2 is a side view showing the mounting mechanism according to the present invention. FIG. 3 is a perspective view of the mechanism. In these drawings, 1 is a ring part, 2 is a bent part, 3 and 9 are overlapping parts, 4 is an inclined part, 5 is a long hole, 7 is a tightening element, 8 is a base part body, and 10 is a rod-shaped part. This shows the main body of the antenna, the base tube.
