Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner compressor accessories, and more specifically, it relates to a silencer cover for an air conditioner compressor. Background Technology

[0002] The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit. The air conditioner compressor is usually installed in the outdoor unit. For fixed-frequency unitary air conditioning units, because their piping system is relatively small, an oil separator is generally not designed. However, in order to reduce the noise generated by the compressor exhaust, a silencer is required as an additional component.

[0003] For example, a noise-reducing cover plate disclosed in patent announcement number CN216922425U improves the sealing performance of the copper tube cover connection point through the setting of a sealing element, avoiding damage to the cover body caused by welding or riveting processes. When the copper tube is connected to the cover body through the sealing element, the inner plug structure ensures the stability of the copper tube assembly.

[0004] While the above method ensures the stability of the copper pipe assembly, it is difficult to separate the copper pipe from the cover after installation. If either the cover or a component of the copper pipe is damaged, the entire cover plate must be replaced, increasing costs. Utility Model Content

[0008] The copper pipe includes a main body and a connector. A connecting ring is fitted onto the main body, and the inner wall of the connecting ring has a thread one. The outer peripheral walls of both the main body and the connector are provided with a thread two that matches the thread one.

[0009] Two connection holes are opened at the end of the copper tube. The two connection holes are symmetrical about the central axis of the copper tube. A spring is installed in the connection hole. A fixing block is hinged to the side wall of the copper tube. The fixing block is placed above the connection hole. One end of the spring is placed in the connection hole and the other end is fixedly connected to the side wall of the fixing block. A docking hole is opened on the inner wall of the air inlet corresponding to the fixing block. The inner wall of the docking hole is arc-shaped and the cross-section of the spring is trapezoidal.

[0010] The connecting ring outer periphery wall is coated with a rubber ring.

[0011] The utility model further sets up as: spring one end passes through the connecting hole and places in the copper pipe, and the one end part of spring placed in the copper pipe is equipped with a hook.

[0012] The utility model further sets up as: the connecting ring outer periphery wall is coated with a rubber ring.

[0013] The utility model further sets up as: the copper pipe inner wall is glued with sound insulation cotton.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] By increasing the fixed block and the butt joint hole, the copper pipe and the cover body are clamped, the stability of the cover body and the copper pipe connection is increased, when disassembling, the connecting ring is rotated out, the connecting head is separated from the main body, the tool is hooked to the hook, the spring is pulled back, the fixed block is separated from the butt joint hole, further, the plug of the lower end of the connecting ring can further seal the cover body, the sealing property of the cover body is increased, when the sound insulation cover plate is damaged, the copper pipe or the cover body can be replaced according to the specific situation, and the cost is saved.
