Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tube storage box equipped with a cutter for cutting plastic tubes used for piping of fluid pressure equipment.

[Prior Art] Conventionally, plastic tubes used for piping of fluid pressure equipment are wound onto a reel to a certain length and stored in a box made of cardboard or the like on the market.

The above tube is pulled out to the required length for piping.
It is used by cutting with a cutter, but if the cut is crushed or becomes diagonal or serrated, the seal between the joint and the joint may become incomplete, so general cutting tools such as scissors or pliers are used. The tube is cut without the use of any tools, using special cutters similar in shape to pliers.

However, the above-mentioned special cutter is a special tool, so it is expensive, easy to lose, and can accidentally cut hard pipes and cause the blade to spill.If there is wear or blade spill, the cut end may be crushed or the blade may become serrated. There is a problem that it has a relatively short lifespan because it deteriorates.

[Problem to be solved by the invention] The purpose of the invention is to provide a tube outlet and a cutter on the side plate on the tube drawer side of the tube storage box, thereby preventing confusion or loss of the tube with a normal cutting tool. The purpose is to provide an inexpensive cutter for cutting tubes.

[Means for Solving the Problems] In order to achieve the above object, the tube storage box with a cutter of the present invention is a tube storage box containing a wound plastic tube, in which the storage box is attached to the side plate on the tube drawer side. The cutter has a tube receiving part that supports the tube substantially perpendicularly to the side plate, a fixed blade attached to the outlet, and a movable blade that moves substantially parallel to the side plate. It is characterized by having the following.

[Operation] When the plastic tube is pulled out to a desired length from the outlet and the cut portion is supported by the tube receiving portion, the tube can be cut approximately perpendicularly to its axial direction by the cutter.

The above cutter has a simple structure and is cheaper than a dedicated cutting tool, and there is no risk of losing it or misusing it with a general cutter, so the sharp blade cuts the tube cleanly. be able to.
