Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bracket, and particularly to a bracket for holding a tube disposed in a resin tank.

[Conventional technology and problems to be solved]

When a tube is placed inside a resin tank, it is necessary to hold the tube within the tank. However, the installation work for holding the tube must not be complicated. Particularly when installing inside a resin tank that is formed into a nearly sealed structure by integral molding, the hole for the tube to pass through, etc.
Since there is usually only a small opening in the tank wall, it tends to be difficult to put hands or tools into the tank to work on the tank, making it complicated to attach the tube by methods such as welding.

An object of the present invention is to provide a tube bracket for a resin tank, which facilitates the installation work for holding the tube in a resin tank, particularly an integrally molded resin tank.

[Means for solving problems]

In order to achieve the above object, the present invention has a specific structure as a tube bracket for a resin tank. a flange portion provided on the proximal end side of the insertion portion, the flange portion having a size larger than the diameter of the hole and welded to the outer surface of the tank; and a tube provided on the distal end side of the insertion portion and disposed within the tank. The tube bracket for a resin tank is characterized by having a clamping part into which the tube bracket is pushed and clamped.

[Effect]

When the insertion part of the bracket of the present invention is inserted into a hole provided in a resin tank and the tube is pushed into a clamping part provided at the distal end side of the insertion part within the resin tank, the tube is clamped by the clamping part. Ru.
The bracket of the present invention is welded to the outer surface of the tank at a flange portion provided on the proximal end side of the insertion portion.

Through the above operations, the tube is supported within the resin tank.

〔Example〕

The present invention will be explained in detail below based on illustrated embodiments.

Embodiment 1 FIG. 1 is a diagram showing a bracket according to an embodiment of the present invention, in which a general tube is held.

In the figure, 1 is an integrally molded resin tank, and the upper part (ceiling part) of this tank 1 is provided with a hole 10 for inserting a bracket. The bracket 2 has a flange portion 11 having a diameter larger than the diameter of the hole 10 at its base end, that is, at its upper end.
This flange portion 11 is the insertion portion 12 of the bracket 2.
The bracket 2 is supported on the tank 1 when the bracket 2 is inserted into the hole 10. The insertion portion 12 of the bracket 2 may have an outer diameter large enough to be inserted into the hole 10, but in this embodiment, only the hole contacting portion below the flange is slightly larger than the inner diameter of the hole 10. It has a small outer diameter, and the outer diameter below it is even smaller.

On the other hand, a stopper 3 is formed at the tip (lower end) of the insertion portion 12 and serves as a holding portion for holding the tube 4 by bending the end inward. To attach the tube 4, first the tube 4 is passed through a hole (not shown) in the wall of the resin tank 1 through which the tube 4 is inserted, and the insertion portion 12 of the bracket 2 is inserted into the hole 10. In FIG. 1, a part of the tube 4 is located at the stopper 3 in a direction substantially perpendicular to the upper outer surface a of the tank.
A part of the tube 4 and the stopper 3 are made to face each other so as to be located at the lower part of the tube. Just like this tube 4
If you push it into stopper 3, it will go straight to stopper 3.
clamps and supports the tube 4. Since the tip of the bent portion of the stopper 3 is formed to be equal or approximately equal to the curvature of the outer surface of the tube 4, the tube 4 does not wobble and has good stability.

The flange portion 11 of the bracket 2 having such a structure is welded to the upper outer surface a of the tank. That is, the flange portion 11 of the bracket 2 and the peripheral edge of the hole 10 of the tank 1 are welded by appropriate means, so that the bracket 2 is attached to the tank 1 at this welding surface 8.
It is firmly fixed to the

As mentioned above, if the bracket 2 of this embodiment is used, the tube is held in the bracket 2 by simply pushing the tube 4 into the stopper 3 as described above, so that the work of attaching the tube 4 in the resin tank 1 becomes easy. In particular, when the resin tank 1 is a resin tank that is formed into a nearly sealed structure by integral molding, there is usually only a small opening in the tank wall so that hands and instruments cannot be inserted into the tank. Since it is difficult to attach the tube 4 using the bracket 2 of this embodiment, it is much easier to attach the tube 4.

Embodiment 2 FIG. 2 shows a case where the present invention is applied to holding a breather tube.

In this case, the bracket 2 has a structure similar to that of the above embodiment, and has a welding surface 8 on the upper part of the resin tank 1.
Since the breather tube 6 is securely fixed to the bracket 2 and has a stopper at its tip, the breather tube 6 is securely held on the bracket 2 and extends into the air chamber 5 so that its tip opening 9 faces the fuel upper limit 7 at a constant height. You can do it.
Therefore, the position of the fuel upper limit remains constant.

In the above embodiments, one bracket 2 is attached to the upper part of the tank, but it is also possible to attach a plurality of brackets.

[Effect of idea]

As explained above, according to the tube bracket for a resin tank according to the present invention, the insertion part is inserted into the hole of the resin tank, and the tube bracket disposed inside the resin tank and the tube bracket provided at the tip side of the insertion part are connected to each other. When the tube bracket for a resin tank and the tube are operated to press the clamping part against the tube, the tube is pushed into the clamping part and is clamped by the clamping part. All that is left to do is to weld the flange on the proximal end of the tube bracket for resin tanks to the outside of the tank to hold the tube inside the resin tank. Work becomes easier.

In particular, if the resin tank is formed into a nearly sealed structure by integral molding, there is usually only a small opening in the wall of the tank, so do not place your hands or instruments inside the resin tank. It tends to be difficult to insert the tube and install the tube.
The above-mentioned tube attachment work is greatly facilitated by the bracket for a resin tank according to the present invention, which can be easily performed by operating the tube and bracket from the outside of the resin tank.
