Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable hose cutter capable of easily cutting a hose.

[0002]

2. Description of the Related Art Conventionally, a cutter knife has been used to cut a hose used for water supply and distribution. To cut the hose with this cutter knife, hold the hose with one hand, apply the cutter knife gripped with the other hand to the hose, and operate the hose by operating the cutter knife in a circle. Disconnect.

[0003]

As described above, conventionally, there is no dedicated hose cutter and a cutter knife is used for cutting the hose, so that the cut end of the hose may be bent and the hose end may be bent. When connecting joints, etc., sometimes it was not possible to make a good connection.

The present invention has been proposed in order to solve the problems of the prior art, and an object thereof is to provide a hose cutter capable of cutting a hose satisfactorily without bending the cut end.

[0005]

In order to achieve this object, a hose cutter according to the present invention has a cutter body having a blade having a mountain-shaped tip, and a lever which is opened and closed with respect to the blade is rotated on the cutter body. It is movably mounted, and a surface of the lever facing the blade is provided with a hose retainer having a recess conforming to the shape of the blade, and a groove portion into which the blade tip of the blade enters is formed in the hose retainer. .

The hose cutter according to the present invention is substantially U-shaped.
A mountain-shaped blade is sandwiched between the upper parts of the character-shaped cutter body, and a substantially L-shaped lever that is opened and closed with respect to the blade is rotatably attached to one end of the cutter body. A hose retainer having a recess matching the shape of the blade is provided on the surface of the lever facing the blade, and a groove for receiving the blade tip of the blade is formed in the hose retainer.

Further, in the hose cutter according to the present invention, a blade having a mountain-shaped tip is attached to a plate-shaped cutter body, and a plate-shaped lever which is opened and closed with respect to the blade is freely rotatable on the base side of the cutter body. The hose retainer having a recess conforming to the shape of the blade is provided on the surface of the lever facing the blade, and the groove into which the blade tip of the blade enters is formed in the hose retainer.

[0008]

According to the above-mentioned structure, the lever is opened, the hose to be cut is sandwiched between the hose retainer and the blade, and the lever is pushed down. Disconnects the hose.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of the hose cutter according to the present invention. 2 shows a rear view of this hose cutter, and FIG. 3 shows a vertical sectional view. In these figures, the cutter body 1 having a substantially U-shape is connected at its central portion by a blade mounting portion 5 which is laterally passed, and the halves 1a and 1b having the blade 9 sandwiched between the blade mounting recesses 2 are separated from each other. It is connected with a tightening screw 4.

Explaining the mounting structure of the blade 9 in detail, the upper part of the blade mounting part 5 facing the blade mounting recess 2 of the cutter body 1 and the inner wall part at the upper end of the projecting parts 6, 7 on the upper side of the body are semi-finished. A holding groove 8 is formed in the opposing portion of the bodies 1a and 1b. The lower end portion and the upper end portions on both sides of the blade 9 having a chevron-shaped tip are sandwiched by these sandwiching grooves 8, and in this state, the half bodies 1a and 1b are joined together by the three tightening screws 4 screwed into the screw holes 3. Has been done.

The tip of one of the protrusions 6 is the lever 1
1 is a rotatably supporting portion 1, and a base portion 12 of a lever 11 sandwiched between the bifurcating fulcrum portions 10 is a fulcrum 1
3 is rotatably connected.

This lever 11 which is opened and closed with respect to the main body 1
Has a substantially L-shape that covers the upper surface of the main body 1 and the outer surface of the other projecting portion 7, and the lower surface of the main body 1 facing the blade 9 is made to conform to the chevron shape of the blade tip. A hose holding portion 14 having a concave portion is formed. A groove portion 15 into which the cutting edge 9a having a V-shaped cross section enters is formed in the center of the hose holding portion 14.

Further, when the lever 11 is closed, the fitting portion 17 formed inside the corner portion of the lever 11 is fitted into the forked notch portion 16 in which the tip portion of the protruding portion 7 is formed. It is like this.

In the hose cutter constructed as described above,
As shown in FIG. 4, the lever 11 is opened, the hose 18 to be cut is sandwiched between the hose holding portion 14 and the blade 9, and the lever 11 is pushed down.
It is easily cut by the mountain-shaped blade 9 while being pressed by 1. At this time, the cutting opening of the hose 18 is accurately cut without bending.

Next, a hose cutter according to another embodiment shown in FIGS. 5 and 6 will be described. In these figures, the blade mounting portion 21 that is upright is provided on the tip side of the flat plate-shaped cutter body 20.
In addition, a chevron-shaped blade 23 is attached to the tip of the blade 23 with its screw facing upward.

Further, a shaft support portion 26 formed on a flat plate-shaped lever 25 is superposed on a shaft support portion 24 formed on the base side of the cutter body 20, so that the cutter body 20 and the lever 25 are provided.
Is rotatably connected by a support shaft 27 inserted through the shaft support portions 24 and 26.

A hose retainer 28 is formed on the surface of the lever 25 that faces the blade 23 of the main body 20 and is recessed to match the chevron-shaped blade 23. The center of the hose retainer 28 is formed. A groove portion 29 into which the cutting edge 23a having a V-shaped cross section enters is formed in the portion.

In the hose cutter constructed as described above,
When the lever 25 is opened, the hose 18 is sandwiched between the hose holding portion 28 and the blade 23, and the lever 25 is pushed down,
While being pressed, the hose 25 is easily cut by the mountain-shaped blade 23 without bending the cut end.

[0019]

As described above, according to the hose cutter of the present invention, a blade having a chevron-shaped tip is attached to the cutter body, and the lever rotatable with respect to the cutter body has a blade on the body side. A hose retainer is formed on the facing surface and a groove is provided in this hose retainer so that the cutting edge fits in.Therefore, insert the hose between the blade on the cutter body and the hose retainer on the lever side, and push down the lever. This has the advantage that the hose can be cut accurately without bending the cut end. As a result, the hose can be easily cut compared to the case of cutting the hose with a cutter knife as in the past, and the cut end does not bend, so when connecting a joint etc. to the end of the hose, connect There is an advantage that the accuracy is improved.
