Description

  The present invention relates to a hose band used when connecting a hose to a connection port of various piping devices.

  When connecting a hose to a connection port provided in various piping equipment such as a blower fan or a faucet, an instrument that fixes the connection between the connection port and the hose by tightening the hose attached to the connection port, so-called "hose" "Clip" is used. As a type of hose clip, there is a so-called “hose band” that tightens the hose by reducing the diameter of an annular band plate. The hose band includes a worm 10 as shown in FIG. By rotating the worm 10, there is one that reduces the diameter of the annular strip 30 provided with the worm groove 31.

  In the hose band 1 using such a worm 10, the housing 20 into which the worm 10 is rotatably inserted is provided on the band plate 30. The housing 20 is formed of a metal plate. It is common. The structure of the housing 20 will be described in detail. As shown in FIG. 5, the housing 20 is formed by bending a metal plate as a raw material, so-called “press molding”. It is formed in a cylindrical shape so that the end 21 and the other end 22 are abutted. The tubular housing 20 is externally fitted to one end side 32 of the band plate 30 and is fixed to the band plate 30. Further, the housing 20 has a bottom 23 at a portion where the one end 21 and the other end 22 of the material are abutted, and the band 23 is located inside the annular strip 30. It is fitted on the plate 30.

  Thus, in the hose band 1 in which the housing 20 is formed of a metal plate, the worm 10 is rotated to reduce the diameter of the annular band plate 30, whereby the hose attached to the connection port is firmly tightened. A great force is applied to 20, and at the bottom 23 of the cylindrical housing 20, the gap between the one end 21 and the other end 22 of the material is widened, and the cylindrical housing 20 is deformed in the radial direction. There is a fear. Therefore, in the conventional hose band 1, the one side edge part 21 and the other side edge part 22 which were faced | matched were welded (refer the code | symbol "a" part of FIG. 5). In addition, in order to fix the housing 20 to the band plate 30, the housing 20 is fixed to the band plate 30 by spot welding the bottom portion 23 of the housing 20 to the band plate 30 (part “b” in FIG. 5). reference).

  The above background art is a general matter, and the applicant of the present application has no particular knowledge of documents describing this background art at the time of filing.

  In the conventional hose band, since one end and the other end of the materials that are abutted with each other must be welded to each other at the bottom of the housing, the manufacturing operation of the housing is complicated. Further, when the housing is assembled to the band plate, the housing must be spot-welded to the band plate, so that the work of assembling the housing to the band plate is complicated.

  This invention is made | formed in view of the said actual condition, and makes it the 1st subject to enable it to simplify the manufacturing operation of a housing. Moreover, let it be a 2nd subject to enable it to simplify the assembly | attachment operation | work of the housing to a strip.

The main means taken by the present invention to solve the above problems are as follows:
“Warm,
A housing in which the worm is rotatably inserted;
The housing is fixed on one end side, provided with a worm groove that engages with the worm on the other end side, and is inserted into the housing so that the other end side is on the outer side of the one end side. A hose band comprising a plate,
The housing is formed into a cylindrical shape so as to abut one end and the other end of the material using a metal plate as a material, and the one end and the other end of the material The bottom part is the outer part fitted to one end side of the strip so that the bottom is the inside of the annular strip.

  In the hose band configured as described above, at the bottom of the housing formed of a metal plate as a material, a protruding piece protruding in the axial direction of the cylindrical housing is provided on each of one end and the other end of the material. Each projecting piece is inserted into a projecting piece insertion portion formed in the band plate. Therefore, at the bottom of the housing, the one end and the other end of the material are restrained from moving in the radial direction of the housing by the projecting piece insertion portion of the band plate, and one side that is abutted against each other It becomes difficult to separate the end and the other end. Therefore, when manufacturing the housing, it is possible to omit welding the one end and the other end of the material, and the manufacturing operation of the housing can be simplified.

In the above means,
“A rectangular relief hole that is drilled in a fixed portion of the housing of the belt plate and escapes the worm,
The hose band is characterized in that the protruding piece insertion portion is constituted by an end portion of the escape hole "
It is good.

  In the hose band configured as described above, since the protruding piece insertion portion is configured using the escape hole for releasing the worm, it is not necessary to provide the protruding piece insertion portion on the band plate separately from the escape hole. Therefore, the band plate provided with the projecting piece insertion portion can be realized with a simple configuration.

In the above means,
“The worm has a head on which a tool is hung and a shaft portion provided with spiral worm teeth on the peripheral surface, and is inserted into the housing in a state where the head contacts the housing. And

The escape hole has an end opposite to the projecting piece insertion portion, and contacts the end of the bottom of the housing opposite to the projecting piece on the side of the housing. Hose band characterized by comprising a fixing part for positioning and fixing "
It is good.

  When the worm has a head on which a tool is hung and the hose band is inserted into the housing in a state where the head is in contact with the housing, when the band plate is firmly tightened, the material on the head side of the worm in the housing The force that separates the one end and the other end is greatly applied, and the housing is easily deformed on the head side of the worm. However, in the hose band configured as described above, the housing is easily deformed at the bottom of the housing. Since the protruding piece is provided on the side so that the one side end portion and the other side end portion of the material are not easily separated from each other, deformation of the housing can be accurately prevented.

  Further, in the hose band configured as described above, a fixing portion is provided on the band plate, and the housing is positioned and fixed with respect to the band plate by bringing the fixing portion into contact with the end portion of the housing. There is no need to perform spot welding like a band, and the housing can be simply fixed to the band plate. Therefore, the work of assembling the housing to the band plate can be simplified.

  In addition, since the projecting piece insertion portion is configured using the end portion of the escape hole of the band plate, and the fixing portion is configured using the end portion on the side opposite to the projecting piece insertion portion in the escape hole, It is not necessary to provide a fixing part on the band plate separately from the escape hole. Therefore, the band plate provided with the fixing portion can be realized with a simple configuration.

  As described above, according to the present invention, the housing manufacturing operation can be simplified. In particular, in the hose band in which the band plate includes a fixing portion that contacts the end of the housing and positions and fixes the housing, the work of assembling the housing to the band plate can be simplified.

  Next, an example as an embodiment of the hose band concerning the present invention is explained in detail.

  As shown in FIG. 1, the hose band 1 according to the present invention includes a worm 10, a housing 20 into which the worm 10 is rotatably inserted, a housing 20 fixed to one end side 32, and a second end 33. A worm groove 31 that meshes with the worm 10 is provided, and a band plate 30 that is inserted into the housing 20 and has an annular shape so that the other end 33 is outside the one end 32 is provided.

  In addition, such a hose band 1 connects a hose to connection ports of various fluid piping devices such as a gas piping device such as a blower fan or a blower duct, a liquid piping device such as a water tap or a hydraulic pressure generator. Although not shown in the drawings, the strip 30 is provided around the hose attached to the connection port of various piping devices, the worm 10 is rotated, and the annular strip 30 is attached. By tightening the hose after reducing the diameter, the hose attached to the connection port is firmly fixed. In particular, it can be suitably used for tightening the hose so that the hose attached to the connection port does not fall off or loosen in various pipes in an environment where intense vibration occurs, such as an air duct of an automobile. Is.

  By the way, as shown in FIG. 2, the housing 20 is formed in a box shape so as to allow the worm 10 to be inserted in a rotatable manner. It is formed by molding, and is formed into a cylindrical shape so that the one end 21 and the other end 21 of the material abut each other so that the one end 32 and the other end 33 of the strip 30 can be inserted. Is formed. And the part where the edge part of the raw material was faced is made into the bottom part 23, this bottom part 23 is fitted inside by the one end side 32 of the strip 30, and it is being fixed to the strip 30. Next, the fixing structure of the housing 20 and the strip 30 will be described in detail below.

  At the bottom 23 of the housing 20, projecting pieces projecting in the axial direction of the cylindrical housing 20 (the circumferential direction of the annular strip 30) on each of the one end 21 and the other end 22 of the material. 24 is provided.

  In the band plate 30, a rectangular relief hole 34 for allowing the worm 10 to escape is provided in a fixed portion of the housing 20, and a projecting piece insertion portion 35 is constituted by an end portion in the circumferential direction of the band plate 30 in the escape hole 34. ing. Further, in the escape hole 34 of the band plate 30, a fixing portion 36 is constituted by an end portion on the opposite side to the above-described protruding piece insertion portion 35.

  When the housing 20 is externally fitted from the tip of the one end side 32 of the band plate 30 and the housing 20 is slid to the fixing position with respect to the band plate 30, the housing 20 is assembled to the band plate 30 as shown in FIGS. As described above, the protruding pieces 24 on the bottom 23 of the housing 20 are inserted into the protruding piece insertion portions 35 of the band plate 30. Accordingly, the one end portion 21 and the other end portion 22 of the material with which the housing 20 is abutted are constrained so as not to be separated from each other, and deformation of the cylindrical housing 20 in the radial direction is prevented. Further, the end surface of the housing 20 opposite to the side on which the projecting piece is provided contacts the end surface of the fixing portion 36 of the band plate 30. Thereby, the housing 20 is positioned and fixed with respect to the strip 30 in the circumferential direction of the strip 30 (the axial direction of the housing 20).

  By the way, in this example, the worm 10 having a head portion 11 having a hexagonal portion on which a tool such as a spanner is hung and a shaft portion 13 provided with spiral worm teeth 12 on the outer periphery is adopted as the worm 10. When the worm 10 is mounted on the housing 20, the head 11 of the worm 10 contacts the housing 20. More specifically, the seating surface of the head 11 of the worm 10 (the end surface on the shaft portion 13 side of the head 11) contacts the end surface of the housing 20 that faces the worm 10. Therefore, when the worm 10 is rotated and the band plate 30 is firmly tightened, a large force is applied to the portion of the housing 20 where the head 11 of the worm 10 contacts, and the side of the worm 10 where the head 11 contacts. The above-mentioned protruding piece 24 is provided at the end of the worm 10 on the head 11 side, and this protruding piece 24 is inserted into the protruding piece of the band plate 30. Since the movement is firmly restrained by being inserted into the portion 35, the housing 20 is not easily deformed even if the band plate 30 is firmly tightened.

  Furthermore, in this example, in the band plate 30, the portion to which the housing 20 is fixed is a bulging portion 37 that bulges outward in the radial direction of the annular band plate 30 than the other portions. The bulging amount of the bulging portion 37 is substantially the same as the thickness of the material of the housing 20, and when the housing 20 is assembled to the strip plate 30, the bottom portion 23 of the housing 20 bulges the strip plate 30. It is accommodated in the outlet 37. Thereby, when the hose is tightened by the band plate 30, a uniform tightening force can be obtained over the entire inner peripheral surface of the band plate 30 without causing large irregularities on the inner surface of the band plate 30 that has become an annular shape. .

  Further, in the escape hole 37 of the band plate 30, the protruding piece insertion portion 35 is constituted by the end portion on the head 11 side of the worm 10, whereas in other words, on the opposite side to the head 11 of the worm 10. For example, the fixed portion 36 is constituted by the end portion of the shaft portion 13 of the worm 10, and the fixed portion 36 is formed in a tongue-like shape protruding on the bulging portion 37. Then, the front end surface of the tongue-shaped fixing portion 36 comes into contact with the end surface of the bottom portion 23 of the housing 20, so that the bottom portion 23 of the housing 20 accommodated in the bulging portion 37 is inserted into the protruding piece insertion portion in the strip 30. The housing 20 is positioned and fixed with respect to the band plate 30 so as to be sandwiched between the portions on both sides of 35 and the front end face of the fixing portion 36. Therefore, the boundary portion between the fixed portion 36 and the housing 20 on the inner surface of the band plate 30 is also a flat surface without large unevenness. From this point, when the hose is tightened by the band plate 30, A uniform tightening force can be obtained over the entire inner peripheral surface.

  In FIG. 4, the illustration of the other end side 33 of the band plate 30 is omitted, but the other end side 33 of the band plate 30 is more specifically between the one end side 32 of the band plate 30 and the worm 10. Is located between the bulging portion 37 of the band plate 30 and the shaft portion 13 of the worm 10 and is inserted into the housing 20 so that the worm groove 31 meshes with the worm teeth 12. Then, when the worm 10 is rotated, the position of the other end side 33 of the band plate 30 with respect to the housing 20 changes, and as a result, the diameter of the entire annular band plate 30 is increased or decreased. This is the same as a conventional hose band.

  Further, the worm groove 31 of the band plate 30 is formed in a slit hole shape through which a material such as a stainless steel plate constituting the band plate 30 is punched, and the slit hole-shaped worm groove 31 is formed on the band plate 30. It is the same as the conventional hose band that the other end side 33 is continuously provided with a plurality at equal intervals in the circumferential direction of the annular band plate 30.

It is a perspective view which shows an example of a hose band. It is the perspective view which looked at the housing of the hose band shown in FIG. 1 from the inner side of the strip. It is the principal part top view which looked at the hose band shown in FIG. 1 from the inner side of the strip. It is AA sectional drawing of FIG. It is the perspective view which looked at the housing of the conventional hose band from the inner side of the strip.
