Description

[Detailed description of the invention] (Field of industrial application) This invention is used in piping work for gas equipment, electrical equipment, hot water supply equipment, etc. in offices and residences. This reel for a flexible tube allows the flexible tube to be smoothly and easily continuously pulled out without staining or damaging the wound flexible tube.

(Conventional technology) In recent years, gas equipment and electrical equipment in offices and residences, etc.
In piping work for water supply equipment and the like, flexible pipes made of synthetic resin and flexible pipes made of metal have come into wide use. For example, in the case of gas equipment piping in ordinary homes, flexible pipes made of polyethylene or polybutylene are widely used in place of conventional metal pipes. In this construction method that uses flexible tubes, workers usually unwind the flexible tubes from the winding drum that wound them up, or unwind the flexible tubes by winding only the flexible tubes in a spiral shape. After unwinding and squeezing it into a straight line by hand and cutting it to the required length, it is supported and fixed along the construction materials in the ceiling and under the floor.

(Problem to be solved by the invention) By the way, when using a winding drum that winds up a flexible tube, the winding drum is fixed on the ground or on a vehicle, and the flexible tube is rotated. However, since the flexible tube is unwound one after another, there is a problem in that unwinding the flexible tube is extremely time-consuming and difficult to improve work efficiency.

Also, when using a flexible tube wound in a spiral, it is necessary to unwind the flexible tube while rotating it in the same way as above, and when unwinding, the flexible tube is damaged. They may come apart and become tangled, and as with the above, there was a problem in that work efficiency was significantly reduced. In particular, if the flexible tube is unwound directly on the ground, another problem arises in that the flexible tube may become dirty or damaged.

The present invention solves the above-mentioned problems in piping work using flexible pipes, namely, that it is difficult to unwind the flexible pipes smoothly and it takes a lot of effort to unwind them.
This aims to solve the problem of the flexible tube becoming dirty or damaged when it is unwound.
To provide a reel for a flexible tube which allows a wound flexible tube to be smoothly and easily continuously drawn out, and prevents the flexible tube from becoming dirty or damaged during drawing out.

(Means for Solving the Problems) The flexible tube reel according to the present invention has a frame-shaped body frame with an open front surface and a rotatable protective rod and a guide roller on the circumference; a take-up reel which is rotatably and detachably supported by the reel body, one side plate is detachable from the reel body and into which a spirally wound flexible tube can be fitted; and the side plate is removably fixed to the reel body. It consists of a locking mechanism.

Further, the take-up reel may be provided with a locking device capable of locking the end of the flexible tube.

(Function) When using the flexible tube reel, first insert the take-up reel into the main body frame, then operate the lock mechanism to remove the side plate of the take-up reel from the reel main body, and then twist it into a spiral shape. The wound flexible tube is fitted onto a take-up reel, the end of the flexible tube is locked in the locking part, and the removed side plate is fixed to the reel body by a locking mechanism.

Then, the main body frame is placed vertically or horizontally on the ground or on a vehicle, and the tip of the flexible tube is pulled out from a position near the guide roller. At this time, the flexible tube protrudes due to the protective rod of the main body frame,
It is smoothly and efficiently pulled out by the guide roller while preventing staining and damage. In addition, since the end of the flexible tube is locked to the stopper of the take-up reel, the take-up reel rotates smoothly and reliably as the flexible tube is pulled out, and as a result, the winding on the take-up reel is This prevents the flexible tube from digging into the area where it is exposed.

When the wound flexible tube is used up, the side plate of the take-up reel is removed from the reel body again, and a new flexible tube is set on the take-up reel. On this occasion,
Since the side plate can be easily removed from the reel body using the lock mechanism, the flexible tube can be set quickly and easily.

Further, in the above embodiment, one flexible tube reel 1 is used to pull out the flexible tube 12, but two flexible tube reels 1 are arranged side by side to pull out two flexible tubes 12 at the same time. You can do it like this.

(Effects of the invention) As mentioned above, the flexible tube reel of the invention has a main body frame with a rotatable protective rod and a guide roller on the circumference, and a reel with one removable side plate. Since the reel is rotatably and detachably supported, even if the flexible tube is wound in a spiral, the flexible tube can be pulled out smoothly and easily by setting it on the take-up reel. This can be done continuously, greatly improving work efficiency. Of course,
The protective rod can prevent the flexible tube from protruding, becoming dirty, or being damaged when it is pulled out.

In addition, since the take-up reel is provided with a locking device that can lock the end of the flexible tube, the take-up reel rotates smoothly and reliably as the flexible tube is pulled out, and the flexible tube The flexible tube can be pulled out smoothly.

Furthermore, since one side plate of the take-up reel is configured to be detachable from the reel body using a lock mechanism, the side plate can be easily removed or attached with one touch, and the flexible tube can be set quickly and easily. I can do it.

However, since the take-up reel is rotatably supported within the frame-shaped main body, the flexible tube can be pulled out even when the main body frame is used vertically or horizontally. As a result, it can be used depending on the portability of the work, which is extremely convenient.

In addition, since the main body frame has a frame shape, the main body frame can be stacked in multiple stages when storing or transporting, which is convenient in practice.
