Description

TECHNICAL FIELD

The present invention relates to an improvement in a holding hole structure on a ship side, particularly to a holding hole structure on a ship side for increasing strength of a cylindrical through hull fitting, as well as linking force between an inner ring and an external surface of a ship, whereby objects like a flagpole, and a fishing rod are conveniently held on the ship side.

BACKGROUND ART

Nowadays foam material is used as stuffing for a boat, which has the advantage of high strength and bearing of high load. Even it is damaged, water cannot leak into an external surface of a ship. Hence it is often applied to lifeboats, transport boats and fishing boats.

At the side of a boat, there is at least a holding hole seat, for setting a flagpole, a fishing rod and so on. A conventional holding hole seat normally comprises an inner ring and an outer ring, wherein the outer ring is extending at the bottom and thereby building up a cylindrical through hull fitting; wherein the inner ring and outer ring are screwed together, whereby an external surface of a ship is pressed between the inner ring and the outer ring. Thereby it is achieved that the cylindrical through hull fitting is set in an external surface of a ship for holding flagpole, fishing rod and so on.

A conventional inner ring and cylindrical through hull fitting are formed mostly in one piece made of PVC. However, heat resistance and strength of the cylindrical through hull fitting made of PVC are limited. During injecting foam material into the ship side layer, the cylindrical through hull fitting can become deformed or broken.

Besides, since fixing of the inner ring in the external surface of a ship is only possible through connection with the outer ring, the inner ring and the cylindrical through hull fitting are pressed in the ship side layer, as soon as the outer ring is taken down, while the external surface of a ship is still not filled with foam material.

In view of these disadvantages the inventor performed continuous testing and improvement and developed the present invention.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a holding hole structure on ship side for holding a flagpole, fishing rod and others.

For achieving above object, the present invention comprises: an inner ring, wherein there is a first outer flange on the top; wherein the said first outer flange is set in the middle area of the external surface of a ship; and a cylindrical through hull fitting, which is fastened to the inner ring at the top.

Preferably, inside the inner ring, there is a first inner thread for setting cylindrical through hull fitting and/or other parts.

Preferably, the inner ring is connected with an external reinforcement ring; wherein outside the external reinforcement ring there is a first outer thread and on the top a third outer flange; wherein the first outer thread is screwed with the first inner thread of the inner ring, hence the external surface of a ship is pressed between the first outer flange of the inner ring and the third outer flange of the external reinforcement ring. Thereby the linking force between the inner ring and external surface of a ship is increased, thus the load bearing of the cylindrical through hull fitting is improved.

Preferably, inside the external reinforcement ring there is a second inner thread, connected with a cylindrical through hull fitting fixing ring; wherein outside the cylindrical through hull fitting fixing ring there is a second outer thread; wherein the second outer thread is screwed with the second inner thread of the external reinforcement ring and the bottom of the cylindrical through hull fitting fixing ring is withstanding the top of the cylindrical through hull fitting, whereby the cylindrical through hull fitting is fastened.

Preferably, on the top of the cylindrical through hull fitting fixing ring there is a fourth outer flange; wherein on the top of the fourth outer flange there is a convex-concave structure for rotating the cylindrical through hull fitting fixing ring to fasten the cylindrical through hull fitting.

Preferably, on the middle of the inner ring there is a first inner flange; on the top of the cylindrical through hull fitting there is a second outer flange; after the cylindrical through hull fitting has passed through the inner ring, the second outer flange is fastened to the first inner flange. Thereby the cylindrical through hull fitting and the inner ring are fastened together conveniently.

Preferably, at the bottom of the inner ring there is a second inner flange; the inside diameter of the second inner flange is slightly larger than the outer diameter of the cylindrical through hull fitting, so that strength of the cylindrical through hull fitting is improved.

The inner ring is sticking with a sticking layer; wherein the sticking layer is covering the inner ring from the bottom, and the sticking layer is sticking fixed on middle area of the external surface of a ship, whereby the inner ring and the cylindrical through hull fitting are fixed in the external surface of a ship stably.

Other aspects and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawing, illustrating by way of example the principles of the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

As shown in FIG. 1-3, the present invention a holding hole structure on ship side 100 comprises: an inner ring 1, having a first outer flange 11 on the top; wherein the first outer flange 11 is set in the middle area of an external surface of a ship-101; and a cylindrical through hull fitting 2, of which the top is fastened to the inner ring 1; an external surface of a ship-101 and the cylindrical through hull fitting 2 are connected through the inner ring 1, wherein the cylindrical through hull fitting 2 is made of material like stainless for increasing strength of the cylindrical through hull fitting 2, and improving the linking force between the inner ring 1 and the external surface of a ship-101. Thereby it is achieved, that objects like flagpole, fishing rod are hold on the ship side.

On the top of the inner ring 1 there is a first outer flange 11, for connecting the external surface of a ship 101. The first outer flange 11 is set in the middle area of the external surface of a ship 101, to extend its contact area with the external surface of a ship-101, thereby the fiction between the inner ring 1 and the external surface of a ship 101 is increased, furthermore the inner ring and the catheter are fixed in the external surface of a ship stably. For saving cost, an inner ring of the gas nozzle of a conventional ship side can be used as the inner ring 1.

Since the top of the cylindrical through hull fitting 2 is fastened to the inner ring 1 together, the catheter is fixed with the inner ring 1 together in the external surface of a ship 101, to hold such like fixing buckle seat, lamp holder, flagpole, fishing rod and so on. Thereby it is achieved, that fixing buckle seat, lamp holder, flagpole, fishing rod and so on are set in the ship side conveniently.

As shown in FIG. 3-4, the cylindrical through hull fitting 2, which is detachably fastened to the inner ring 1, is made of material other as the inner ring 1, therefore it can be made of material with higher strength, like stainless steel for increased heat resistance and strength, thus deformation or rupture cannot happen, during filling foam material in the external surface of a ship-101.
