Description

[Detailed Description of the Invention] The present invention relates to a hose band that fits around a hose connected to the caps of various devices, and tightens the hose by reducing the diameter of a tightening ring using an external force.

One type of hose band that tightens the hose by applying external force and reducing the diameter of the tightening ring.
A tightening ring is formed by turning a long and thin plate into a circular shape, and the proximal end of a tightening piece that protrudes outward from the tightening ring is fixed to one end of the plate, and the plate is attached to the tip side of the tightening piece. The other end is fixed, and by tilting the clamping piece toward one end of the plate, the other end is pulled to reduce the diameter of the clamping ring, and the tip of the clamping piece is tightened with a clip. There are hose bands that are fixed to a ring, but in the past, the tightening piece and the end of the plate were fixed by spot welding, which made the fixing work time-consuming and costly. Moreover, the fastening force was insufficient and the fastening piece easily came off when tightening.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hose band that eliminates the above-mentioned drawbacks, increases the adhesion force between the fastening piece and the plate material, and can be easily and inexpensively manufactured.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 is a long and thin plate made of steel plate, aluminum plate, etc. As shown in Fig. 1, by bending this plate 1 into a circular shape, the inner diameter when not in use is the same as the outer diameter of the hose to be tightened. A clamping ring 2 larger than the diameter is formed, one end of the plate 1 is bent outward of the clamping ring 2, and
The other end similarly protrudes largely outward from the tightening ring 2.

As shown in FIG. 3, the bent portion 3 on the one end side of the plate material 1 has a cylindrical protrusion 11 formed by burring in the vicinity of the proximal end and the distal end, respectively.
and 12, the protrusion 11 on the proximal end side of the tightening piece 10 is fitted into the through hole 4 formed in the bent part 3,
It is fixed by caulking the tip of the protrusion 11 and pushing it apart, and the protrusion 12 on the tip side of the fastening piece 10 is formed on the protruding end 6 of the other end of the plate material 1. The fastening piece 10 and the other end of the plate material 1 are fixed by fitting into the through hole 7 and caulking the tip of the protrusion 12 in the same manner as described above and pushing it apart.

Then, as shown in FIG. 1, after fitting the U-shaped clip 15 inside the tightening ring 2, it is fitted onto the connecting part of the hose fitted into the mouthpiece (not shown), and the tightening piece 10 is attached to the As shown in FIG. 3, when the plate 1 is tilted clockwise around the bent portion 3 at one end, the protruding end 6 at the other end of the plate 1 fixed to the tightening piece 10 is pulled. As shown in FIG. By bending and fixing the tip of the clip 15, the hose is held in a tightened state.

The hose band of this embodiment has cylindrical protrusions 11, 1 formed by punching out the tightening piece 10 by burring.
2, and these protrusions 11 and 12 are fitted into the through holes 4 and 7 formed in the plate material 1, and the tips thereof are pressed and spread to fix them. Therefore, the welding process is not necessary, and , tightening piece 10 and plate material 1
can be firmly fixed to each other, and there is no fear that the tightening piece 10 will come off from the plate material 1 during tightening work or the like.

Note that, contrary to the above embodiment, the bent portion 3 of the plate material 1
It is also possible to form cylindrical protrusions on each of the protruding ends 6 by burring, and to form through holes in the fastening piece 10 to fit these protrusions.

That is, in the hose band of the present invention, a tightening ring is formed by turning a long and thin plate into a circular shape, and the proximal end of a tightening piece protruding outward from the tightening ring is fixed to one end of the plate. At the same time, the other end of the plate is fixed to the tip side of the tightening piece, and the tightening piece is tilted toward the one end of the plate to pull the other end to tighten the tightening ring. In the hose band which has a reduced diameter and has a tip end of the tightening piece connected to the tightening ring, a cylindrical protrusion is formed by punching on either the tightening piece or the plate material, and the protrusion The gist is that the fastening piece and the plate material are fixed to each other by inserting the part into a through hole formed in the other side and pushing and expanding the tip part thereof, which is different from the conventional fastening piece and the plate material. Compared to the case where the parts are fixed by spot welding, the manufacturing process can be simplified and costs can be reduced because no welding process is required. Since the tips of the protrusions are pushed apart and fixed, the fixing force is stronger than in the case of welding, and it is effective in reliably preventing the fastening piece from coming off the plate material.
