Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe fixture.
More specifically, the present invention relates to a pipe fixing tool that is attached to a U-shaped curved pipe in an outdoor unit of an air conditioner and that suppresses vibration of the pipe.

[0002]

2. Description of the Related Art In an outdoor unit of an air conditioner, a pipe connected to a compressor is often curved in a U shape in order to suppress vibration. In order to suppress the vibration of the U-shaped pipe more effectively, a pipe fixture that acts as a weight is conventionally attached to such a pipe.

For example, as a pipe fixing device of this type, there is one using a rubber member having a substantially elliptic cylindrical shape (for example, Japanese Patent Laid-Open No. 5-8317). The rubber member is formed with two through holes arranged in the axial direction and slits radially extending from the through holes to the outer peripheral surface. Then, the parallel portion of the pipe is fitted into each through hole of the rubber member through each of the slits, and its outer peripheral surface is bound with a plastic band so that the rubber member does not move along the pipe. Or, it is designed to be sandwiched between metal leaf springs.
Thereby, the natural frequency of the pipe can be changed by the action of the weight, and the vibration of the pipe can be suppressed.

[0004]

However, in the above-mentioned conventional pipe fixing tool, when the rubber member is attached to the pipe at the stage of assembling the outdoor unit of the air conditioner, a mark indicating a position to be attached is required. For this reason, there is a problem in that such a mark must be attached to the pipe in advance. Further, even if such a mark is provided on the pipe, the position where the rubber member is actually attached varies in the work. As a result, the pipe fixture overlaps with the member arranged near the pipe and the work is restricted. There's a problem.
Moreover, since it is necessary to tie the outer peripheral surface of the rubber member with a plastic band or to pinch it with a metal leaf spring, there is a problem that the material cost and the working man-hours are large and the cost is high.

Therefore, an object of the present invention is to enable accurate installation of a pipe bent in a substantially U-shape or a substantially U-shape without marking, and reduce the material cost and the man-hour required for the work to reduce the cost. It is to provide a pipe fixture that can be reduced.

[0006]

In order to achieve the above object, the pipe fixture according to claim 1 is a pipe fixture made of an elastic material which is attached to a pipe bent in a substantially U-shape or a U-shape. A main body extending in one direction, and a rod-shaped foot portion that extends in a direction perpendicular to the one direction and that is continuous with the center of one end surface of the main body, and the main body has both sides in the longitudinal direction. A pair of first through holes that are arranged and have substantially the same diameter as the parallel portion of the pipe and that extend parallel to the direction in which the foot extends, and along each of the through holes, from the through holes to the outer circumference of the main body. A first cut through is provided, and the foot portion has substantially the same diameter as a portion of the pipe sandwiched by the parallel portions (hereinafter, referred to as “curved portion”), and has a longitudinal direction of the main body. A second through hole that extends parallel to and along this through hole It is characterized in that the second cut leading to the foot outer periphery is provided from through holes.

The pipe fixing device according to a second aspect of the present invention is the pipe fixing device according to the first aspect, wherein the pipe fixing device projects from the outer periphery of the foot portion in a direction perpendicular to the extending direction of the foot portion and the extending direction of the main body. It is characterized in that it is provided with a protruding portion.

The pipe fixing device according to a third aspect of the present invention is the pipe fixing device according to the second aspect, characterized in that projections and depressions are provided on the tip end surface.

Further, a pipe fixing device according to a fourth aspect is the pipe fixing device according to any one of the first to third aspects, in which a portion of the outer peripheral surface of the main body along the longitudinal direction is
It is characterized in that a curvature substantially the same as that of a member arranged near the pipe is given.

[0010]

According to the pipe fixing device of the present invention, the parallel portion of the pipe which is bent in a substantially U-shape or a substantially U-shape to be fixed is fitted into each first through hole of the main body through the first cut. Then, the curved portion of the pipe is attached to the pipe by fitting the curved portion of the pipe into the second through hole of the foot through the second cut.

In this case, the mounting position of the main body is defined by fitting the curved portion of the pipe into the second through hole of the foot portion. That is, the distance between the main body and the curved portion of the pipe is set equal to the distance between the second through hole of the foot portion and the root of the main body. Therefore, when the main body is attached to the pipe, the mark indicating the position to be attached is not required, and the attachment is performed accurately. Further, the mounting position of the main body is defined by fitting the curved portion of the pipe into the second through hole of the foot portion and does not vary. Therefore, this pipe fixture is arranged near the pipe in operation. There is no problem that the work is restricted by overlapping with the formed members. Moreover, since the main body is in the state of being locked to the curved portion of the pipe through the foot portion, it does not slide along the parallel portion of the pipe. Therefore, it is not necessary to bind the outer peripheral surface of the main body with a band made of plastic or sandwich it with a leaf spring made of metal. Therefore,
Material costs and man-hours are reduced, and costs are reduced.

According to another aspect of the pipe fixing device of the present invention, there is provided a projecting portion projecting from the outer periphery of the foot portion perpendicularly to the extending direction of the foot portion and the extending direction of the main body. For example, when assembling an outdoor unit of an air conditioner,
First, the pipe fixture is attached to the pipe, and the pipe is connected to a compressor, an accumulator, or the like in a state where the protruding portion abuts a member (for example, a bottom frame) arranged near the pipe. Thereby, the pipe is accurately positioned with respect to the member. Therefore, the assembly accuracy of the outdoor unit of the air conditioner is improved.

In the pipe fixing device according to the third aspect, since the projections have the projections and depressions on the tip end surfaces, the tip end surfaces elastically contact the member. That is, the convex portion of the tip end surface flexibly abuts against the above member in a state in which it can be slightly compressed and expanded. Therefore, for example, after assembling the outdoor unit of the air conditioner, even if the above-mentioned pipes vibrate during the operation of the compressor or the like, the vibration of the pipes is effectively absorbed. This also reduces noise associated with vibration.

According to a fourth aspect of the present invention, a portion of the outer peripheral surface of the main body along the longitudinal direction is provided with a curvature substantially the same as that of a member (eg, accumulator) arranged near the pipe. ing. For example, when assembling an outdoor unit of an air conditioner, first attach the pipe fixing device to the pipe, and place the pipe in a compressor or accumulator in a state in which the portion having the curvature abuts the member. Connecting. Thereby, the pipe is accurately positioned with respect to the member. Therefore, the assembly accuracy of the outdoor unit of the air conditioner is improved.
