Abstract

<P>PROBLEM TO BE SOLVED: To provide a pipe clamp for preventing a collision of an oscillating pipe (A) and a pipe (B). <P>SOLUTION: A fixed-diameter clamp component 1 and a variable diameter clamp component 11 are connected to each other by a first connection part 7 and a second connection part 16, and form a parallel pipe clamp 30a or a cross pipe clamp 30b depending on whether they should be turned at 90° or not during the connection. Both the parallel pipe clamp 30a and the cross pipe clamp 30b connect the pipe (A) to the pipe (B) by holding the pipe (A) by a first holding part, and holding the pipe (B) by a second holding part. Thus, the resonance of the pipe (A) or the pipe (B) by vibration given from a compressor or the like can be suppressed, or the clearance between the pipes (A) and (B) is maintained even during the resonance, and the collision of the pipes can be prevented. Furthermore, two kinds of pipe clamps for parallel clamping and cross clamping need not be prepared. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention belongs to the technical field of piping clamps for connecting piping to piping.

For example, when a pipe resonates due to vibration from the compressor, the pipe may collide with a parallel running pipe or an intersecting pipe and be damaged.
For this reason, conventionally, in parallel running pipes, both pipes are connected by sandwiching rubber between both pipes and winding a resin band around both pipes to tighten them. After wrapping rubber around the pipe, the two resin bands were wound like a sash to connect both pipes to prevent collision of the pipes due to resonance.

nothing special.

  In order to put both pipes in a connected state by winding and tightening a resin band (or similar) on two pipes as described above, there must be enough space around the pipes for workers to enter. I had to. In addition, the workability is not good, and there are various problems such that the degree of tightening varies from worker to worker.

  An object of the present invention is to solve various problems when bundling pipes with a resin band or the like.

The pipe clamp according to claim 1 is:
A pipe clamp configured by connecting a first part having a first gripping part for gripping a pipe and a second part having a second gripping part for gripping the pipe;
A connection mechanism for connecting the first part and the second part is:
A parallel connection in which the pipe gripped by the first gripping part and the pipe gripped by the second gripping part are parallel;
The pipe gripped by the first gripping part and the pipe gripped by the second gripping part are variable to a cross connection that crosses at 90 degrees,
The first part and the second part are connected while being selected from the parallel connection and the cross connection.

  The pipe clamp is configured by connecting a first part and a second part by a connecting mechanism. The first part can grip the pipe at the first gripping part, and the second part can grip the pipe at the second gripping part. In other words, the pipe clamp grips the pipe (A) with the first gripping part and grips the pipe (B) with the second gripping part, so that the pipe clamp is stretched between the pipe (A) and the pipe (B). Connect the pipe (A) and the pipe (B). As a result, the pipe (A) or the pipe (B) can be prevented from resonating due to vibrations applied from a compressor or the like, and even if the pipe is resonated, the distance between the pipes (A) and (B) is maintained by the pipe clamp. The collision of the pipes (A) and (B) is prevented.

  Moreover, the connection mechanism includes a parallel connection in which the pipe (A) gripped by the first gripping part and the pipe (B) gripped by the second gripping part are parallel, and a pipe gripped by the first gripping part ( A) and the pipe (B) gripped by the second gripping portion are variable to a cross connection that crosses at 90 degrees, but the first part and the second are selected from the parallel connection and the cross connection. Since the parts are connected, when the pipes (A) and (B) are running side by side, the pipes (A) and (B) are used by connecting the first part and the second part in parallel connection. Are crossed, the first part and the second part may be connected, and it is not necessary to prepare two types of pipe clamps for parallel use and for cross use.

Both the gripping of the pipe (A) by the first gripping part and the gripping of the pipe (B) by the second gripping part are simple operations compared to the binding by the resin band. That is, the workability is improved and the tightening degree does not vary for each worker.
Further, when a resin band or the like is wound around two pipes, it has been necessary to secure a space around the pipes so that an operator's hand can enter. Is small.

  The piping clamp according to claim 2, wherein the first part or the second part is provided with an elastic material that comes into contact with a counterpart when the first part or the second part is connected by the connecting mechanism. It is a clamp. If comprised in this way, it can suppress that a vibration transmits to a 2nd component (pipe (B)) from a 1st component (pipe (A)), or the contrary with an elastic material.

  The pipe clamp according to claim 3 is a pipe clamp according to claim 2, wherein when connected by the connecting mechanism, a part of the connecting mechanism comes into contact with the elastic material. Since it is a part of the coupling mechanism that makes contact with the elastic material, the effect of claim 2 is improved.

Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.
[Example]
[Constant Clamp Parts]
First, the configuration of the constant diameter clamp component 1 corresponding to the first component will be described with reference to FIG.

The constant-diameter clamp component 1 is composed of a main body portion 2 made of hard resin (for example, nylon, PP, PE, POM, PPE, etc.) and an elastic portion 3 that is an elastomer.
The main body portion 2 includes an elastic gripping portion 4 including a C-shaped portion 4a having a structure corresponding to that obtained by cleaving a cylindrical side surface along an axis, and a guide portion 4b connected in a folded manner to the cleavage end portion. Is equipped.

The elastic part 3 covers most of the C-shaped part 4a. The inner peripheral portion of the elastic portion 3 is a holding groove 3a that is open on the side of the guide portion 4b, and the inner surface is provided with streak-like irregularities.
The elastic gripping portion 4 and the elastic portion 3 function as a first gripping portion. In this embodiment, the elastic gripping portion 4 and the elastic portion 3 are for a φ6.35 mm metal tube (for example, a copper tube). That is, between the guide portions 4b, the φ6.35 mm metal tube is allowed to pass while elastically deforming the elastic gripping portion 4 outward, and the holding groove 3a is elastically deformed when the φ6.35 mm metal tube is pushed. This is received, and after receiving, it is dimensioned to press the outer periphery of the metal tube with elastic repulsive force.

  In general, the constant diameter clamp component 1 is attached to a metal tube after the metal tube is piped. Since the first gripping portion has the above-described configuration, the work is performed by connecting the guide portion 4b to the metal tube. It is only necessary to press the first gripping part against the metal tube after pressing against the outer periphery. That is, one touch is sufficient.

The bottom portion of the elastic gripping portion 4 is connected to the first connecting portion 7 via the connecting pillar 6. Specifically, a substrate portion 8 is provided continuously at the lower end of the connecting column 6, and a snap column 9 is erected on the substrate portion 8. A pair of elastic pieces 10 are connected to the tip of the snap column 9 to form a so-called arrowhead-type snap. In addition, the 1st connection part 7 is a part of connection mechanism.
[Variable diameter clamp parts]
Next, the configuration of the variable diameter clamp part 11 corresponding to the second part will be described with reference to FIG.

The variable diameter clamp component 11 includes a main body portion 12 made of hard resin (for example, nylon, PP, PE, POM, PPE, etc.) and an elastic portion 13 that is an elastomer.
The main body portion 12 is provided with a second connection portion 16 having a U-shaped structure including a connection plate 14 and a pair of side walls 15. The second connecting part 16 constitutes a connecting mechanism together with the first connecting part 7.

  The connecting plate 14 is provided with an opening-shaped snap receptacle 17 in which a semicircle is attached to each square piece. A pair of elastic pieces 10 can pass through the substantially square opening portion formed by the straight portion 17a of the snap receptacle 17 by elastic deformation. Here, since the opening part formed by the linear part 17a is substantially square, the pair of elastic pieces 10 are snap receptacles in two types of relative postures rotated 90 degrees around the axis of the snap receptacle 17. 17 can pass. In either of the two types of relative postures, the side surface portion of the snap column 9 is fitted into any pair of the semicircular portions 17b facing each other.

Both ends of the pair of side walls 15 are connected to the clamp base portion 21, and the U-shaped second connection portion 16 and the clamp base portion 21 form a cylindrical structure.
A base end portion of a C-shaped band portion 22 is connected to the clamp base portion 21, and a multi-stage locking portion 23 and a knob 24 made up of a plurality of protrusions are provided at the distal end portion of the band portion 22.

In addition, a fixed guide 25 and an elastic guide 26 are provided upright at the end of the clamp base 21, and a multistage locking portion 23 can be inserted between them.
When the multistage locking portion 23 is inserted and one of the projections of the multistage locking portion 23 hits the tip projection 27 of the elastic guide 26, the elastic guide 26 is elastically deformed away from the fixed guide 25, and the projection deforms the tip projection 27. When it passes, it elastically returns to the fixed guide 25 side, and the protrusion (multistage locking portion 23) is locked by the tip protrusion 27. Since the leading end of the band portion 22 is captured by this locking, the band portion 22 and the clamp base portion 21 form a closed ring. This closing ring is used to grip the pipe.

  The elastic part 13 is attached to the clamp base 21 in a wrapping manner. A part of the elastic part 13 enters the closed ring, and the other part is formed by the second connecting part 16 and the clamp base 21. It has entered the tubular structure.

  The band part 22, the clamp base part 21, and the elastic part 13 (parts in the closed ring) function as a second gripping part. The outer diameter of the pipe that can be gripped by the second gripping portion varies depending on which projection of the multistage locking portion 23 is locked to the tip projection 27, and in this embodiment, a metal tube having a diameter of 9.52 to 12.7 mm Can be gripped.

  In general, the variable diameter clamp component 11 is attached to a metal pipe after the metal pipe is piped. However, since the second gripping part has the above-described configuration, the work is performed by using the band part 22 to attach the metal pipe. After winding, it is only necessary to insert the multistage locking portion 23 between the fixed guide 25 and the elastic guide 26 and lock it to the tip protrusion 27. That is, it is a simple operation.

The knob 24 attached to the band portion 22 can be picked up when the multistage locking portion 23 is inserted between the fixed guide 25 and the elastic guide 26.
On the other hand, the knob 28 attached to the elastic guide 26 can release the engagement of the multistage locking portion 23 by the tip protrusion 27 by pulling the elastic guide 26 and pulling the elastic guide 26. The knob 24 can also be used to pull back the band portion 22 from which the multistage locking portion 23 is unlocked.
[Piping clamp]
The constant-diameter clamp part 1 corresponding to the first part and the variable-diameter clamp part 11 corresponding to the second part are connected by the first connecting part 7 and the second connecting part 16 and are connected to the parallel pipe clamp 30a (FIG. 3) or The cross piping clamp 30b (FIG. 5) is used.

The difference is whether the pair of elastic pieces 10 are pushed into the snap receptacle 17 at any of the 90-degree rotational positions around the axis of the snap receptacle 17 described above.
In either case, the pair of elastic pieces 10 are pushed into the snap receptacles 17 until the substrate portion 8 contacts the connecting plate 14 and slightly elastically deforms. Then, the elastic piece 10 that has passed through the snap receptacle 17 while being elastically deformed is elastically restored, and its tip is locked to the edge of the snap receptacle 17. Thereby, the fixed diameter clamp component 1 and the variable diameter clamp component 11 are connected.

  In the completed parallel pipe clamp 30a, the pipe (A) gripped by the first gripping part and the pipe (B) gripped by the second gripping part are parallel to each other as shown in FIGS. (Parallel connection). On the other hand, in the cross pipe clamp 30b, as shown in FIGS. 5 and 6, the pipe (A) gripped by the first gripping part and the pipe (B) gripped by the second gripping part cross at 90 degrees. (Cross connection).

  Both the parallel pipe clamp 30a and the cross pipe clamp 30b hold the pipe (A) with the first holding part and hold the pipe (B) with the second holding part, so that the pipe (A) and the pipe (B ) Is connected to the pipe (A) and the pipe (B). As a result, the pipe (A) or the pipe (B) can be prevented from resonating due to vibrations applied from a compressor or the like. Therefore, the collision of the pipes (A) and (B) is prevented.

  Moreover, the coupling mechanism by the first coupling part 7 and the second coupling part 16 is a parallel coupling in which the pipe (A) gripped by the first gripping part and the pipe (B) gripped by the second gripping part are parallel. And the pipe (A) gripped by the first gripping part and the pipe (B) gripped by the second gripping part are variable to a cross connection crossing at 90 degrees, but from the parallel connection and the cross connection Since the constant diameter clamp part 1 and the variable diameter clamp part 11 are connected while being selected, the parallel pipe clamp 30a configured by parallel connection is used when the pipes (A) and (B) are running side by side. However, when the pipes (A) and (B) cross each other, a cross pipe clamp 30b configured by cross connection may be used, and it is necessary to prepare two types of pipe clamps for parallel use and for cross use. Absent.

  Both the gripping of the pipe (A) by the first gripping part and the gripping of the pipe (B) by the second gripping part are simple operations compared to the binding by the resin band. That is, the workability is improved and the tightening degree does not vary for each worker.

  Further, when a resin band or the like is wound around two pipes, it has been necessary to secure a space around the pipes so that an operator's hand can enter. Is small.

In both the parallel pipe clamp 30a and the cross pipe clamp 30b, as shown in FIGS. 4 and 6, the tips of the arrowhead type snaps by the pair of elastic pieces 10 are in contact with the elastic portion 13. If comprised in this way, it can suppress by the elastic part 13 that a vibration transmits to the variable diameter clamp component 11 (pipe (B)) from the fixed diameter clamp component 1 (pipe (A)), or the contrary.

It is an example. Depending on whether the pair of elastic locking pieces 31 are pushed into the cross-shaped snap receptacles 32a and 32a to be locked or pushed into and locked into the 32b and 32b, they can be connected in parallel or in a cross connection.

(C) The first connecting portion 7 has a gate-like structure, and a collar-like elastic locking piece 33 is connected laterally to the gate pillar portion 34 to form the first connecting portion 7, and the main body portion of the second connecting portion 16. Reference numeral 35 denotes an example in which a U-shaped engaging portion 36 is provided on two surfaces as a rectangular parallelepiped shape that can be inserted into the gate post portion 34.
When the main body portion 35 of the second connecting portion 16 is inserted into the gate post portion 34, the engagement portion 36 with which the elastic locking piece 33 engages is determined by either turning 90 degrees or not, Depending on the situation, parallel connection or cross connection can be used.
