Pipeline fixing structure and air conditioner

Technical Field

The invention relates to the technical field of heat exchange equipment, in particular to a pipeline fixing structure and an air conditioner.

Background

There are a large number of pipes in air conditioners, and the trend of the pipes is also various.

In the transportation process of the air conditioner, the phenomenon that the air conditioner falls down can occur due to the jolt of the road surface. In the falling process, the compressor and the pipeline can be subjected to larger impact, so that the U-shaped pipe stretches out the pipeline fixing structure from the chassis under the action of impact force, and fixing failure is caused.

In addition, the air conditioner with the structure has the problems of exceeding stress strain and noise standard when in operation.

Detailed Description

It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless otherwise indicated, terms of orientation such as "upper, lower, top, bottom" are used generally with respect to the orientation shown in the drawings or with respect to the component itself in the vertical, upright or gravitational direction; also, for ease of understanding and description, "inner and outer" refers to inner and outer relative to the profile of each component itself, but the above-mentioned orientation terms are not intended to limit the present invention.

The invention provides a pipeline fixing structure and an air conditioner, which aim to solve the problem that a pipeline fixing structure in the prior art is easy to fail due to impact.

As shown in fig. 1, the air conditioner includes a chassis 40, a pipe fixing structure, a compressor 50 and a pipe 20, the pipe 20 is disposed on the chassis 40 through the pipe fixing structure, the pipe fixing structure is the above pipe fixing structure, the compressor 50 is also disposed on the chassis 40, and when the compressor 50 is operated, the chassis 40 also vibrates.

As shown in fig. 1 to 7, the pipe fixing structure includes a fixing block 10, the fixing block 10 has a cavity for accommodating a pipe 20, an opening communicating with the cavity is formed on an outer surface of the fixing block 10, the pipe 20 is in clearance fit with the fixing block 10, and the pipe 20 can move up and down along the fixing block 10 when the pipe 20 is installed at the cavity and the pipe fixing structure is installed to an assembling position.

When the pipe fixing structure is used, the fixing block 10 is fixed on the chassis 40 of the air conditioner, and the pipe 20 is fixed in the cavity of the fixing block 10. When the air conditioner encounters a falling condition during operation, the pipeline 20 is in clearance fit with the cavity, so that the pipeline 20 can move up and down in the cavity, the impact is relieved, the connection failure of the pipeline fixing structure and the chassis 40 is avoided, and the assembly flexibility and the buffering performance of the pipeline fixing structure are improved.

That is, the pipe fixing structure of the present invention can solve the problem that the pipe fixing structure is detached from failure due to the impact force of the compressor 50. In addition, by interference fit, the friction force between the pipe 20 and the fixing block 10 can be reduced, thereby reducing the pulling force of the pipe 20 on the fixing block 10.

Optionally, the travel of the conduit 20 relative to the fixed block 10 is greater than or equal to 15 millimeters. Referring to fig. 3, the pipe 20 is thus capable of being displaced in the Z direction relative to the fixed block 10 when vibrating. The fixing block 10 can not be pulled up from the chassis 40 directly, and the connection failure of the pipeline fixing structure and the chassis 40 is effectively avoided.

In the embodiment shown in fig. 5 to 7, two openings are provided, one opening is an elongated hole 11, the other opening is circular, and the length of the elongated hole 11 extends in the vertical direction. In fig. 3, the vertical direction is the Z direction. Since the elongated hole 11 is formed, the pipeline has a certain movement space in the Z direction, so that buffering is performed by movement, and the pipeline fixing structure is prevented from being directly separated from the chassis 40.

To ensure that the conduit 20 is able to move relative to the fixed block 10, the width of the elongate aperture 11 is equal to or greater than the diameter of the conduit 20. When the width of the elongated hole 11 is smaller than the diameter of the pipe 20, the pipe 20 is locked by the elongated hole 11, thus preventing the movement of the pipe 20. Thus, by adjusting the width of the elongated hole 11 to be slightly larger than the diameter of the pipe 20, the movement jam can be avoided.

In the embodiment shown in fig. 3, when the compressor 50 vibrates the pipe 20, small vibrations are generated in the X direction by the pipe 20 and the fixed block 10, and the pipe 20 can move relative to the fixed block 10 in the Z direction.

In the embodiment shown in fig. 4, the elongated hole 11 includes a first long side 111, a bottom side 112, a second long side 113 and an upper side 114 connected in sequence, the first long side 111, the second long side 113 and the upper side 114 are linear, and the bottom side 112 is arc-shaped. Typically, the conduit 20 is supported at the chassis 40 and is bounded left and right by a first long side 111 and a second long side 113. This makes the elongated hole 11 resemble a U-shaped hole.

Alternatively, the thickness of the cavity is equal to the width of the elongated hole 11. The width of the elongated hole 11 is equal to or greater than the diameter of the pipe 20, so that when the thickness of the cavity is equal to the width of the elongated hole 11, the thickness of the cavity is slightly greater than the diameter of the pipe 20. In this way, a clearance fit between the fixed block 10 and the pipe 20 is ensured. And is convenient for processing the cavity.

As shown in fig. 3, it should be noted that the gap between the chamber and the pipe 20 should be as small as possible. When the compressor is operated, the vibration of the pipe 20 is in fact in the X direction, and therefore, it is necessary to limit the vibration of the pipe 20 in the X direction. In the drop impact test, the pipeline 20 receives a force in the Z direction, so that a gap is needed in the X direction, i.e., the left-right direction, and the pipeline 20 can move up and down in the Z direction, so that the pipeline cannot be locked.

By vibration analysis of the compressor 50, the pipeline 20 and the pipeline fixing structure, it is known that the pipeline 20 vibrates perpendicular to the plane of the pipeline 20, rather than along the axial direction (i.e. the Z direction) of the pipeline 20, so that the movement stroke in the Z direction between the pipeline 20 and the pipeline fixing structure is increased, and the reliability of the constraint of the pipeline fixing structure on the pipeline 20 is not affected.

Alternatively, the height of the cavity is equal to the length of the elongated hole 11. Please refer to fig. 7. Thus, the method has the characteristic of convenient processing.

In order to ensure a reliable device, the outer surface of the fixing block 10 is provided with an assembly gap 12, two sides of the assembly gap 12 are communicated with two openings, the cavity comprises a pipeline positioning channel 13 and a sliding cavity 14 communicated with the pipeline positioning channel 13, the pipeline positioning channel 13 is arc-shaped, and the pipeline 20 is positioned at the pipeline positioning channel 13 after entering the sliding cavity 14 through the assembly gap 12. By providing the sliding chamber 14, the travel of the tubing 20 up and down during dropping can be increased, thereby avoiding failure of the tubing securing structure to the chassis 40.

Specifically, the thickness of the sliding chamber 14 is equal to the width of the elongated hole 11. Likewise, the direction in which the thickness of the sliding chamber 14 is referred to herein is the X direction in FIG. 3.

In the embodiment shown in fig. 7, the projection of the sliding cavity 14 in the plane perpendicular to the thickness direction of the fixed block 10 is composed of a first arc-shaped edge 141, a first straight edge 142 and a second straight edge 143, wherein the radian of the first arc-shaped edge 141 is equal to the radian of the pipeline positioning channel 13 and is located inside the outer edge 131 of the pipeline positioning channel 13; the first straight edge 142 is flush with the surface of the fixed block 10 having the elongated hole 11 and the second straight edge 143 is parallel to the upper edge 114 of the fixed block 10. That is, the sliding chamber 14 here has a trapezoid-like structure in fig. 7. With this structure, the movement stroke of the pipe 20 is increased.

As shown in fig. 2 to 4, the pipe fixing structure further includes a positioning boss 30, the positioning boss 30 is disposed on the bottom surface of the fixing block 10 and protrudes toward the chassis 40, and when the pipe fixing structure is mounted to the assembly position, the positioning boss 30 is clamped on the chassis 40 and can move up and down relative to the chassis 40. By providing the positioning boss 30, the fixed block 10 can be ensured to be reliably connected with the chassis 40.

Specifically, the positioning boss 30 includes a guide post 31 and a clip 32, the top end of the guide post 31 is connected with the bottom surface of the fixing block 10, the clip 32 is mushroom-shaped, the clip 32 is disposed at the bottom end of the guide post 31, after the pipe fixing structure is mounted to the assembly position, the clip 32 passes through the chassis 40 and is located below the chassis 40, and the thickness of the chassis 40 is smaller than the length of the guide post 31. During a fall, the clip 32 is not easily detached from the chassis 40 because the length of the guide post 31 is greater than the thickness of the chassis 40. The fixing block 10 limits the pipeline 20 in the X direction in fig. 3, so that horizontal vibration in the working process of the pipeline 20 can be reduced.

Alternatively, the difference in length of the guide post 31 and the thickness of the chassis 40 is greater than or equal to 5 millimeters. In combination with the forward travel of the conduit 20 relative to the fixed block 10 being no less than 15 mm, the conduit securing structure of the present invention has a travel of no less than 20 mm relative to the conduit 20.

The invention adopts the scheme of incompletely wrapping the pipeline 20, so that the pipeline 20 can move up and down relative to the pipeline fixing structure, and the movable allowance is provided to prevent the positioning protruding part 30 from falling out of the chassis 40. Meanwhile, the pipeline fixing structure also has certain constraint on the pipeline 20, so that vibration of the pipeline 20 can be effectively reduced, and noise reduction is effectively carried out on the air conditioner.

According to the invention, the travel of the pipeline and the pipeline fixing structure moving up and down in the falling process is increased, so that the pulling force of the pipeline on the pipeline fixing structure is reduced, and the problem of failure caused by the fact that the pipeline fixing structure is separated from the chassis in the falling process of the air conditioner can be effectively solved.

The invention mainly improves the fixing effect of the pipeline fixing structure through the following three aspects.

1. The sliding cavity is arranged, so that the pipeline can move relative to the fixed block, and when the pipeline falls, the pipeline is buffered by moving, so that the pipeline fixing structure is prevented from falling out of the chassis;

2. the cavity of the fixed block is in clearance fit with the pipeline so as to reduce friction between the pipeline and the fixed block, thereby reducing the pulling force of the pipeline on the fixed block;

3. the length of the guide post of the positioning protruding part is increased, so that the matching length of the pipeline fixing structure and the chassis is increased, and the up-and-down moving stroke of the pipeline fixing structure is increased.
