Description

[Detailed Description of the Invention] This invention relates to a connecting fitting for the top of a cylinder, which is used when connecting an auxiliary pillar to the top of a cylinder or fixing necessary equipment.

Conventionally, when increasing the height of communication cylinders and other cylinders, or installing TV cameras or other equipment at the end of the cylinder, there are no suitable connection fittings, so special fittings must be made on-site, or the circular However, this method not only increases on-site work and reduces work efficiency, but also has various problems such as the reliability of the connection depends on the skill of the worker and the installation cost is relatively high. Ta.

However, this invention solves the above-mentioned conventional problems by fixing the connecting disk to the end of the cylinder that can be fitted and fixed to the top of the cylinder, making it possible to connect easily, easily, inexpensively, and with high reliability. .

That is, to explain this invention with reference to an embodiment, a reinforcing cylinder 3 is fitted to the upper part of a cylinder 2 that can be fitted to the upper part of a cylinder 1, and a connecting disk 4 is concentrically abutted and fixed to the upper end of the reinforcing cylinder 3. Reinforcing ribs 5, 5 are fixed at equal intervals between the reinforcing cylinder 3 and the connecting disk 4 (for example, fixed by welding), and nuts 6.6 are fixed to the side wall of the cylinder 2 at diametrically symmetrical positions. A fixing bolt 7.7 is screwed onto 6.6 to form a connecting fitting.

Connecting bolt holes 10, 10 are provided on the concentric circumference of the connecting disk 4.
are drilled at equal intervals, and a through hole 11 is provided in the center.

If the through hole 11 is provided, it is possible to plate the inner surface of the connecting fitting when plating it, and if the diameter is large enough to fit the hand, it is convenient to handle the connecting bolt 12.

For example, when connecting the auxiliary strut 8 to the upper end of the cylinder 1, the connecting fitting of this invention can be extremely easily and easily connected by fixing the lower end flange 9 of the auxiliary strut 8 and the connecting disk 4 with the connecting bolt 12. The auxiliary support 8 can be firmly connected.

Furthermore, when installing a Tervi camera, fixing the camera stand and the connecting disk allows for simple, easy, and reliable installation.

The stop bolt not only fixes the cylinder to the cylinder, but can also be used as a foothold during work by making it of appropriate dimensions.

Although fixing the nut is the most reasonable method, it is not limited to this.

In other words, according to this invention, ``It is only necessary to fit the cylindrical part into the cylindrical ring, so the connection is extremely simple, and since the connecting part is reinforced by the connecting disk, it is even stronger than other parts. be.

However, if a bolt is screwed into a nut fixed to the cylindrical side wall, the tip of the bolt will push the cylindrical wall into the cylindrical wall,
The relationship between the two can be made even stronger.

Further, by using a slightly tapered cylinder (matching the taper of the cylinder), the fitting between the two can be made even tighter.

In addition, connection bolt holes are drilled in the connecting disk on the concentric circumference and inside the auxiliary cylinder, so other members such as auxiliary supports can be firmly connected to the top of the cylinder, and the bolts enter into the cylinder. Therefore, there are various effects such as there is less risk of rusting, etc., and there is no risk of rainwater entering inside from the bolt hole.

Further, since the connecting disk is fixed onto the reinforcing cylinder, there are no restrictions on the length and material of the cylinder 2, and there is an advantage that suitable materials can be used.
