Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioner compressor technical field more specifically, it relates to a sound-absorbing pack air inlet pipe. BACKGROUND

[0002] Air conditioner compressor can install sound-absorbing pack to realize the reduction of noise, and the middle part of copper steel sound-absorbing pack is made of steel material, and the air inlet and the air outlet on both ends thereof are copper air inlet pipe and air outlet pipe.

[0003] For example, the sound-absorbing pack air inlet pipe disclosed in the authorized announcement No. CN219081799U sets a buffer part and a circular plate on the air inlet pipe, when the airflow enters the buffer part from the body, the airflow expands, thus causing the generation of negative pressure, and the airflow has a buffering effect, thereby reducing the airflow velocity, when the airflow passes through the buffer part with small cross-sectional area, the airflow increases its passing speed due to the reduced passing space, and when the airflow passes through the inclined air outlet hole of the circular plate, the flow direction generates turbulent flow, thereby avoiding the generation of high-speed airflow.

[0004] In the above, although the generation of high-speed airflow can be avoided, the circular plate is clamped with the air inlet pipe, so that the user is difficult to disassemble the circular plate, and when the circular plate is damaged, the entire air inlet pipe has to be replaced, thereby increasing the use cost.

[0013] The utility model further sets up: the one end of the ejector rod that is placed outside the body is equipped with the block.

[0014] The utility model has the beneficial effects that compared with prior art:

[0015] When needing to fix the round plate on the body, the ejector rod is pushed out to make the clamping block and the annular groove clasp, when the round plate needs to be replaced, the spherical body is pressed to make the spherical body retract, under the elastic force of spring one, the clamping block is pulled back into the connecting hole, thereby separating the round plate and the clamping block, realizing the quick disassembly of the round plate, only the round plate needs to be replaced, and the use cost is reduced.

[0019] The technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0020] In the description of the utility model, it is understood that the terms "up", "down", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or position relationship shown in the drawing, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.

[0021] Working principle: When the circular plate 2 needs to be disassembled, the ball 8 is squeezed. Under the pressure, the second spring 7 contracts, and the ball 8 is squeezed into the connecting hole 3. At this time, there is no force on the push rod 4 to fix it. Under the elastic force of the first spring 5, the locking block 6 retracts into the connecting hole 3. At the same time, the locking block 6 moves out of the annular groove. At this time, under the action of gravity, the circular plate 2 can be taken out from the body 1.

[0022] When the circular plate 2 needs to be installed, place the circular plate 2 inside the body 1, and then push the push rod 4 so that the push rod 4 slides in the connecting hole 3. When the ball 8 slides to the position of the fixing hole, under the elastic force of the second spring 7, the ball 8 is ejected and stuck in the fixing hole, and the push rod 4 is limited. At this time, the snap-fit ​​block 6 snaps into the annular groove to fix the circular plate 2.

[0023] like Figs. 1-2 As shown,

[0024] It includes a hollow body 1 and a circular plate 2 connected to the body 1. The body 1 has a cavity, which is filled with sound-absorbing cotton 9. The sound-absorbing cotton 9 can absorb the airflow noise brought by the gas passing through, thus achieving the sound-absorbing function.

[0025] The main body 1 is provided with a pressure relief part, and the pressure relief part extends into a buffer part. Several vent holes are provided on the circular plate 2. An annular groove is provided on the outer peripheral wall of the circular plate 2. Two connecting holes 3 are symmetrically provided on the inner wall of the buffer part. A fixing component is provided in the connecting hole 3, and the circular plate 2 is fixed by the fixing component.

[0026] The fixing assembly includes a push rod 4, a spring 5, and a snap-fit ​​block 6. One end of the push rod 4 is placed outside the body 1, and a block 10 is provided at the end of the push rod 4 outside the body 1 to prevent the push rod from falling off.

[0027] The other end of the push rod 4 is connected to the snap-fit ​​block 6. The spring 5 is sleeved on the outer peripheral wall of the push rod 4. The push rod 4 is slidably connected to the connecting hole 3. The connecting hole 3 is provided with a step part connected to the spring. The step part can prevent the spring 5 from falling out of the connecting hole 3.

[0028] The two ends of spring 5 are fixedly connected to the side wall of snap-fit ​​block 6 and the inner wall of step, respectively.

[0029] A spring 7 is fixedly connected to the outer wall of the top rod 4. A ball 8 is fixedly connected to the end of the spring 7. A fixing hole communicating with the connecting hole 3 is opened at the end of the body 1. The ball 8 is placed in the fixing hole. The fixing of the position of the locking block 6 is achieved by the ball 8 engaging with the fixing hole.

[0030] The side wall of spring 5 has an opening for spring 2 7 to extend out, so as to prevent spring 5 from affecting the operation of spring 2 7.

[0031] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any change and replacement within the technical scheme of the present application made by those skilled in the art shall be included in the protection scope of the present application.
