Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is directed to a flexible hose in which crests protruding vertically in the longitudinal direction vertically cut crests of a flexible hose repeatedly provided with a trough in between. It relates to a cutting jig.

[Prior Art] Conventionally, in order to cut a mountain portion of a flexible hose vertically, the flexible hose is manually pressed, and a cutting blade such as a saw is vertically applied to the cutting position to cut, or a stationary piece such as a piece of wood is cut. Used and cut it as a guide.

[Problems to be Solved by the Invention] However, when cutting the mountain portion of the flexible hose in order to connect a pipe having the same outer diameter as the outer diameter of the flexible hose, the mountain portion of the flexible hose projects vertically from the flexible hose. Therefore, when disconnecting,
When cutting while leaning, the cutting blade was sometimes displaced from the cutting point. In such a case, the mountain portion of the flexible hose has an uneven cross-sectional shape, and when connecting with another pipe or the like, the fitting was not successful. In addition, the hand holding the flexible hose may be injured due to the deviation of the cutting blade.

Therefore, the present invention aims to solve the above problems, and to provide a flexible hose cutting jig that vertically cuts the crests of the flexible hose without shifting and does not hurt the hand. is there.

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration as a means for solving the problems. That is, the cutting blade is provided with two rings, in which the protrusion protruding perpendicularly to the longitudinal direction is provided on the inner circumference with the protrusion that fits in the valley of the flexible hose repeatedly provided in the longitudinal direction with the valley interposed therebetween. A slit corresponding to the crest of the insertable flexible hose is opened, and the two rings are connected to each other by a connecting portion that extends over the slit, and each of the two rings is formed in half and each half is formed. The ring ends are connected by an engaging hinge so that they can be opened and closed, and the other ring end can be locked in a closed state by a stopper, and the cutting blade is provided along the slits of the two rings. This is the configuration of a flexible hose cutting jig, which is characterized in that a guide is provided to prevent displacement when inserting the flexible hose.

[Operation] Half of each ring is opened by the rotation of the hinges provided on each of the two rings. The opened ring can be closed by a hinge, which can be fitted on a flexible hose. At this time, the protrusion on the inner circumference of the ring fits into the valley of the flexible hose, and the slit is located at a position corresponding to the crest of the flexible hose. The stop then locks the ring closed.
A cutting blade is inserted along the slit. At that time, the guide prevents the cutting blade from being displaced when the cutting blade is inserted, and the mountain portion of the flexible hose is cut vertically.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a relationship between a flexible hose cutting jig and a flexible hose of this embodiment.

In the flexible hose 1 using the flexible hose cutting jig 10 of the present embodiment, the ridges 3 projecting vertically in the longitudinal direction are repeatedly provided on the outer periphery in the longitudinal direction with the valleys 5 interposed therebetween.

As shown in FIGS. 2 to 4, the flexible hose cutting jig 10 fitted to the flexible hose 1 is provided with two rings 12 and 13 having an inner circumference to which the outer circumference of the flexible hose 1 fits. On the inner circumference of the rings 12 and 13, there are protrusions that fit into the valleys 5 of the flexible hose 1.
15 and 16 are provided on the whole except for the ring end portions 22, 23, 27 and 28 to be described later. The protrusions 15 and 16 are made of a soft material such as rubber so as to come into close contact with the valley portion 5 of the flexible hose 1. A slit 18 having a width into which a cutting blade such as a saw (not shown) for cutting the flexible hose 1 can be inserted is formed between the two rings 12 and 13. Moreover, this slit 18 is a flexible hose 1
It is located between the projections 15 and 16 that fit into the valley portion 5 of the above, and is opened at the center of the top of the mountain portion 3 located between the valley portions 5 of the flexible hose 1. Further, the connecting portion 20 is hung over the outside of the rings 12 and 13 beyond the slit 18 so that the cutting blade can completely pass through the slit 18 between the rings 12 and 13 and cut the flexible hose 1. Ring 12,
13 are connected.

On the other hand, each of the rings 12 and 13 is formed in half with the same size and divided into two. Each half ring end 22, 23 has a hinge 25 provided by welding on its outer periphery,
They are engaged and connected at 26. With the hinges 25 and 26, the other ring ends 27 and 28 can be opened and closed. In addition, a snap lock 3 that is a stopper is attached to the ring ends 27 and 28.
0 and 31 are provided by welding, and the snap locks 30 and 31 can lock the ring ends 27 and 28 in a closed state.

Around the slit 18, it protrudes to the outside of the rings 12 and 13 so as to prevent displacement when inserting a cutting blade along the slit 18, and the tip is opened in a Y shape so that the cutting blade can be easily inserted. A guide 34 is provided on the entire outer periphery except for the ring ends 22, 23, 27, 28.

Next, the operation of the flexible hose cutting jig 10 configured as described above will be described.

First, the snap locks 30 and 31 are removed, and the hinges 25 and 26 are rotated to open the halved rings 12 and 13 from the ring ends 27 and 28, respectively. The protrusions 15 and 16 of the opened rings 12 and 13 are fitted into the troughs 5 of the flexible hose 1, and the hinges 25 and 26 are rotated in the opposite direction to close the rings 12 and 13, and the snap lock 30, Lock the ring ends 27, 28 at 31. At this time, since the mountain portion 3 of the flexible hose 1 is located below the slit 18, the guide 34 provided along the slit 18 prevents the cutting blade from being displaced and slits the cutting blade.
Insert into 18 and cut the flexible hose 1. After the cutting blade cuts the flexible hose 1, remove the cutting blade from the slit 18, remove the snap locks 30 and 31, and hinges 25 and 26.
Rotate to open rings 12 and 13. Then, the flexible hose cutting jig 10 is removed from the flexible hose 1.

In this embodiment, since the slit 18 is fixed on the mountain portion 3 of the flexible hose 1 and the guide 34 is provided on substantially the entire circumference of the slit 18, the flexible hose 1 does not shift the cutting blade by the slit 18 and the guide 34. The mountain portion 3 can be easily and vertically cut. Therefore, since the cross-sectional shape of the flexible hose 1 is uniform, the connectivity with other pipes and the like is improved. Moreover, since it is not necessary to press the flexible hose 1 by hand unlike the conventional case, the hand is not damaged. Furthermore, since the protrusions 15 and 16 are made of a soft material, they stick to the flexible hose 1 and the rings 12, 13
It does not slip inside. Moreover, since the snap locks 30 and 31 are used as the stoppers, the ring ends 27 and 28 can be completely stopped, and the stoppers can be cut accurately without coming off during use.

Various modifications can be freely made in the present invention without departing from the gist thereof.

[Effect of the Invention] As described in detail above, according to the flexible hose cutting jig of the present invention, the slit and the guide allow the cutting blade to be easily and vertically cut without being displaced from the crest portion which is the cutting point. Therefore, the connectivity with other pipes is improved. Further, since it is not necessary to press the flexible hose by hand, the cutting blade is not displaced and the hand is not injured, which is convenient for cutting the mountain portion of the flexible hose.
