Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner muffler installation, in particular to an air conditioner muffler installation and positioning device. Background Art

[0002] With the popularity of air conditioners in every household and their widespread use in different spaces, how to solve the air conditioner noise is also a technical field that still needs to be continuously improved. The most commonly used compressor in current household air conditioners is the rolling rotor compressor. The rolling rotor compressor mainly drives the sleeve-shaped piston to continuously roll in the cylinder through its internal eccentric main shaft, thereby achieving the practical purpose of periodic changes in the volume of the suction chamber and the exhaust chamber. However, this working method will force the refrigerant to be under pressure, produce periodic pulsations, and radiate harmonic noise with the compressor rotation frequency as the base frequency. This noise will be continuously transmitted to the indoor unit heat exchanger through the pipeline with the refrigerant as the medium, affecting the user experience.

[0003] In order to solve the noise, current air conditioners usually install expansion mufflers to reduce the transmission of noise. The principle of the expansion muffler is to use the cross-section in the pipe to cause sudden changes in acoustic impedance during the sound wave transmission process, so as to achieve reflection and interference of the sound waves and achieve the purpose of noise reduction. In order to firmly install the muffler, it is usually necessary to use bolts to fix it. However, the operator needs to accurately align the bolts with the reserved holes during the installation process, and the muffler and the docking pipe need to maintain a certain docking angle during the tightening of the bolts, which makes the operation difficult.

[0004] In order to solve the above problems, we have made improvements and proposed an air conditioner muffler installation and positioning device. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-5 As shown, an air conditioner muffler installation and positioning device includes a muffler 1 and a docking pipe 2, a first positioning block 3 is installed at the end of the muffler 1, a second positioning block 4 is installed at the end of the docking pipe 2, a plurality of umbrella frames 8 are installed at the end of the first positioning block 3, a docking cavity 14 is opened at the end of the second positioning block 4, and a limiting column 15 is slidably installed inside the docking cavity 14.

[0023] The muffler 1 is composed of a main body 101 and two docking joints 102, which are respectively fixedly installed at both ends of the muffler 1. The inner diameter of the first positioning block 3 is consistent with the outer diameter of the docking joint 102, and the first positioning block 3 and the docking joint 102 are threadedly connected to firmly connect the first positioning block 3 and the docking joint 102. The inner diameter of the second positioning block 4 is consistent with the docking pipe 2, and the second positioning block 4 is threadedly connected to the docking pipe 2 to firmly connect the second positioning block 4 and the docking pipe 2.

[0024] A first rubber gasket 10 is fixedly installed on the inner surface of the first positioning block 3, and the lower surface of the first rubber gasket 10 contacts the end of the muffler 1 to avoid air leakage at the connection between the first positioning block 3 and the muffler 1. A second rubber gasket 12 is fixedly installed on the end of the first positioning block 3. When the first positioning block 3 and the second positioning block 4 are tightly connected with bolts 7, the docking pressure will squeeze the second rubber gasket 12 to avoid air leakage caused by a gap between the first positioning block 3 and the second positioning block 4. A circular first connecting piece 5 is fixedly installed on the outer surface of the first positioning block 3, and a plurality of mounting holes 6 are opened on the surface of the first connecting piece 5.

[0025] A plurality of connecting columns 13 are fixedly installed at the end of the first positioning block 3. The connecting columns 13 penetrate the first rubber gasket 10 outwardly. The ends of the connecting columns 13 are fixedly connected to a plurality of umbrella frames 8 respectively. The positions of the umbrella frames 8 and the docking cavities 14 correspond one to one, and the inner diameter of the docking cavity 14 is larger than the widest diameter of the umbrella frame 8, so that the umbrella frame 8 can enter the docking cavity 14 and penetrate into its end.

[0026] A limit column 15 is penetrated through the side surface of the docking cavity 14, and the limit column 15 is slidably connected to the second positioning block 4. The end of the limit column 15 is fixedly installed with the limit block 9. A spring 16 is wound around the outer surface of the limit column 15, and the spring 16 is fixedly connected to the inner top surface of the docking cavity 14. The end of the spring 16 is fixedly connected to the outer surface of the limit block 9. When the umbrella frame 8 enters the docking cavity 14 from the outside to the inside, the curvature of the umbrella frame 8 pushes the limit column 15 upward. At this time, the spring 16 is compressed. After the widest part of the umbrella frame 8 passes under the limit column 15, the spring 16 recovers to make the limit column 15 fall, and the umbrella frame 8 is limited to the inside of the docking cavity 14.

[0027] A second connecting piece 11 is fixedly installed on the outer surface of the second positioning block 4. A plurality of bolts 7 are passed through the second connecting piece 11. The positions of the bolts 7 correspond to the mounting holes 6 one by one. The bolts 7 are threadedly connected to the second connecting piece 11 and the mounting holes 6. The first positioning block 3 and the second positioning block 4 can be tightly connected by passing the bolts 7 through the mounting holes 6 and tightening them.

[0028] Magnets with opposite magnetic poles are installed at the top of the umbrella frame 8 and the end of the docking cavity 14, respectively, so as to facilitate the alignment of the umbrella frame 8 with the docking cavity 14 and reduce the difficulty of positioning.

[0029] Working principle: When using this type of air conditioner silencer installation and positioning device, the first positioning block 3 and the docking joint 102 are threaded and tightened until the lower surface of the first rubber gasket 10 is in close contact with the end of the muffler 1, and the second positioning block 4 is threaded and tightened with the docking pipe 2. When the umbrella frame 8 enters the docking cavity 14 from the outside to the inside, the curvature of the umbrella frame 8 pushes the limit column 15 upward. At this time, the spring 16 is compressed. After the widest part of the umbrella frame 8 passes under the limit column 15, the spring 16 recovers to make the limit column 15 fall, and the umbrella frame 8 is limited to the inside of the docking cavity 14. The bolt 7 is passed through the mounting hole 6 and tightened to tightly connect the first positioning block 3 and the second positioning block 4 to complete the installation of the muffler.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
