Description

  The present invention relates to a resin band for holding and fixing a heat insulating cover body covering a pipe so that a water pipe or the like has a heat insulating structure.

  It has been practiced to cover the outer peripheral surfaces of metal pipes and resin pipes with a heat insulating material with a vertically divided structure or a structure with a vertical cut to achieve heat insulation and cooling of the pipe line. A fixing band is employed as a means for fixing an outer cover member or the like that further covers the surface of the heat insulating material.

  As shown in Patent Document 1 (Japanese Patent Laid-Open No. 2002-295788, FIG. 5), this general fixing band includes a male screw provided in a box at the end of the band and a groove portion of the band through which the box passes. As a special structure, a tape band wound in a spring shape as disclosed in Patent Document 2 (Japanese Patent Application Laid-Open No. 2004-263787) is known.

  Further, as shown in Patent Document 3 (Japanese Patent Laid-Open No. 2002-88829, FIG. 3), the resin band has a cylindrical head at the end of the band and is locked to the inner surface of the insertion hole of the cylindrical head. A protrusion is provided, a locking groove is provided on the surface of the band, the band is inserted into the insertion hole from the other end of the band, and the band is secured by locking the locking protrusion and the locking groove. Realized.

FIG. 5 of Japanese Patent Laid-Open No. 2002-295788. JP 2004-263787 A. FIG. 3 of Japanese Patent Laid-Open No. 2002-88829.

  When a metal band is adopted, naturally a problem of rust occurs, and if stainless steel is employed as described in Patent Document 2, it becomes expensive.

  The resin band can be produced by molding, and it is easy to select the material depending on the purpose of use, such as the degree of flexibility. However, as in the band described in Patent Document 3, the resin band is inserted into the insertion hole in the cylindrical head. If the locking structure of the locking protrusion and the locking groove on the surface of the band part is adopted, if the flexibility of the material of the entire band is increased, the locking strength of the locking part will be reduced (disengaged). It is necessary to have appropriate rigidity.

  For this reason, when the band is wound around the tightening attachment target portion, the tubular head portion and the band portion continuous to the head portion remain linear to some extent, and the portion is lifted from the tightening attachment target. Become. And there exists a problem that the linear part of a band bends with progress of time, and fastening will loosen.

  Further, when removing the band when replacing the heat insulating material or the like, the band portion must be cut and cannot be used again.

  In view of this, the present invention proposes a resin band for a pipe cover in which the band is in close contact with the object to be tightened and does not loosen over time and is detachable.

  The resin band for a pipe cover according to the present invention (Claim 1) is an elongated band-shaped band part in which locking grooves are formed in tandem on the surface, and a mounting part through which the band is inserted and attached to one end of the band part. The mounting portion includes a side plate portion that is continuous with the front end side surface of the band portion, and is formed by the side plate portion, the top plate portion, and the bottom plate portion at a position appropriately separated from the front end of the band portion. The insertion hole is provided, a locking projection is formed on the lower surface of the top plate part, and a bending notch is formed on the bottom surface side between the band part tip and the insertion hole forming position in the side plate part. To do.

  Thus, the channel tube is covered with a heat insulating cover body (heat insulating material, jacket member = tightening object), the band is wound, and the band is inserted from the end of the band portion into the insertion hole of the mounting portion. When the fastening portion is tightened, the engagement groove of the band portion and the engagement protrusion of the attachment portion are engaged to be in a state of being prevented from coming off, and the presence of the bending notch provided on the side plate portion of the attachment portion causes the attachment portion to Since the device itself bends at the location, the mounting portion comes into close contact with the surface of the tightening mounting object.

  Therefore, the band can be mounted in close contact regardless of the diameter of the object to be tightened and does not loosen over time.

  Further, the pipe cover resin band according to the present invention (Claim 2) is the pipe cover resin band, in particular, the shape of the notch for bending is semicircular at the back and one side of the opening direction is expanded. The mounting portion is bent more smoothly.

  Furthermore, the resin band for a pipe cover according to the present invention (Claim 3) forms the operation portion by separating the range of the inner side portion of the side plate portion on the base side of the top plate portion except for the joint portion at the front and rear intermediate positions. At the same time, a locking projection is provided on the rear surface of the front side of the operation unit, and the base side is flipped upward.

  Therefore, the operating part has a structure that can swing around the joint part.When the rear part of the operating part is pushed down, the locking projection part is moved upward. The engagement between the stop protrusion and the locking groove is released, and the band portion can be extracted.

  The configuration of the present invention is as described above, and in the band tightening mounting, the mounting part itself is bent and mounted, so that the mounting part of the tightening mounting target is not related to the diameter of the tightening mounting target. It is possible to provide a resin band that is in close contact with the surface and is firmly attached and does not loosen over time.

  In addition, the operation part can be formed by separating the part where the locking protrusion is provided, excluding the joint part that becomes the swing axis, so that the band part can be removed, and the band can be removed without damaging the resin band. It was possible to do.

  Next, an embodiment of the present invention will be described. The resin band for a pipe cover shown in the embodiment includes a long band-shaped band portion 1 and a mounting portion 2 through which a band provided at one end of the band portion 1 is inserted and mounted by integral molding of resin (nylon resin). Produced.

  The band portion 1 is formed by vertically forming locking grooves 12 in the longitudinal direction on the surface of a long band-shaped main body 11 and providing nail holes 13 at appropriate intervals.

  The mounting portion 2 has a cylindrical shape including a side plate portion 21, a top plate portion 22, a bottom plate portion 23, and an operation portion 24, and the side plate portion 21 is continuous with the front end side surface of the band portion 1. A band insertion hole 25 is formed by the top plate portion 22 and the bottom plate portion 23 on the distal end side.

  Further, on the side of the bottom surface of the side plate portion 21 between the front end connecting portion of the band portion 1 and the position where the insertion hole 25 is formed, the back side is semicircular and the one side in the opening direction is a widening slope toward the front side. A notch 26 is formed.

  The operation part 24 is formed by separating the range of the inner part of the side plate part 21 on the base side of the top plate part 22 except for the joint part 27 at the front and rear intermediate position. A locking projection 28 that engages with the locking groove 12 is provided on the rear surface, and the base side is flipped upward to form an operation finger rest 29.

  Thus, the predetermined flow pipe A is covered with the heat insulating material B and the jacket member C (clamping mounting object), and the band is wound around to fix the clamping mounting object. In the band winding, the band 1 is inserted into the insertion hole 25 of the mounting portion 2 from the end of the band body 11 of the band portion 1 to tighten the band, and the locking groove 12 of the band portion 1 and the locking protrusion of the mounting portion 2 are tightened. The part 28 is engaged to be in a retaining state.

  In particular, the presence of the bending notch 26 provided on the side plate portion 21 of the mounting portion 2 allows the mounting portion 2 itself to bend at the relevant location, so that when tightened firmly, the surface of the tightening mounting object (C is not employed). The surface of B or the surface of C in this case is bent. Moreover, the mounting portion 2 can be bent more smoothly, in particular, by making the shape of the bending notch 26 a semicircular shape at the back and a side of the opening direction having a widening slope.

  Therefore, regardless of the diameter of the object to be tightened, the band can be attached substantially closely, and the gradual deformation caused by the fact that it is a resin member having a predetermined flexibility over time. There is no possibility of occurrence of tightening, and tightening is not loosened.

  When the operating finger rest 29 is pushed downward, the operating unit 24 swings around the joint 27, so that the front part moves upward, and the engagement between the locking projection 28 and the locking groove 12 is achieved. It is cancelled | released and it becomes possible to extract the band part main body 11 from the insertion hole 25. FIG.
