DETAILED DESCRIPTION

[0028] The following description is used to disclose the utility model so that those skilled in the art can realize the preferred embodiments in the following description of the utility model, and those skilled in the art can think of other obvious variants.

[0029] Embodiment 1

[0030] Please refer to Figures 1-9 The utility model provides a kind of air conditioning unit noise reduction device, including air conditioning unit body 1, two noise reduction shells 2 being set to air conditioning unit body 1 exterior, four abutting seats 6 being set to the both sides of air conditioning unit body 1 and being arranged in L shape, support seat 18 being set to the top of air conditioning unit body 1, multiple spring shock absorbers 19 being evenly fixed to the top of support seat 18, multiple dampers 20 being evenly fixed to the top of support seat 18 at the position of one side of spring shock absorber 19, positioning seat 17 being fixed to the inner cavity of one of air conditioning unit body 1 at the position of one side of support seat 18 and acting on the noise reduction replacement mechanism of air conditioning unit body 1, support seat 18 and one of air conditioning unit body 1 between slidingly and being connected, the side of support seat 18 and positioning seat 17 between being connected and being arranged in insertion mode;

[0031] Noise reduction replacement mechanism includes lifting assembly acting on air conditioning unit body 1;

[0032] When the noise reduction effect of the spring shock absorber 19 and the damper 20 is reduced due to the fatigue life after long-term use, the abutting seat 6 at the bottom of the air conditioning unit body 1 can clamp the surfaces on both sides of the air conditioning unit body 1 and can lift the air conditioning unit body 1 by a certain distance, so that the user can pull out the support seat 18 from the cavity formed by the two air conditioning unit bodies 1, and then insert the replaced support seat 18 and the spring shock absorber 19 and the damper 20 fixed on the surface of the support seat 18 into the cavity formed by the two noise reduction shells 2, and then lower the height of the air conditioning unit body 1 by the lifting assembly, so that the bottom of the air conditioning unit body 1 abuts against the top of the spring shock absorber 19 and the damper 20 at the adjacent position, thereby quickly replacing the spring shock absorber 19 and the damper 20 when the noise reduction effect of the spring shock absorber 19 and the damper 20 is reduced due to the fatigue life after long-term use. The position of the support seat 18 at the bottom of the air conditioning unit body 1 can be limited by the positioning seat 17.

[0033] Please refer to Figures 1-9 The lifting assembly includes a rod groove 3 opened in the inner surface of the noise reduction shell 2, a first threaded rod 4 rotatably connected to the inner cavity of the rod groove 3, a threaded sleeve 5 rotatably connected to the upper and lower ends of the outer circumferential surface of the first threaded rod 4, a connecting rod 7 fixed to the middle position of one of the abutting seats 6 and the abutting seat 6, a translation component acting on the other abutting seat 6, and a rotation component synchronously driving the first threaded rod 4 to rotate. The threaded structures of the first threaded rods 4 on both sides of the air conditioning unit body 1 are arranged in opposite directions, and the top of the first threaded rod 4 extends through the noise reduction shell 2 and reaches the top of the noise reduction shell 2.

[0034] When the height of the air conditioning unit body 1 needs to be raised, the position of one of the abutting seats 6 in the horizontal direction is adjusted by the translation component to abut against the surfaces on both sides of the air conditioning unit body 1, so that when one of the first threaded rods 4 is rotated, the first threaded rods 4 are synchronously rotated under the driving action of the rotation component. Since the inner cavity of the rod groove 3 can abut against and limit the threaded sleeve 5, the threaded sleeve 5 can drive the abutting seat 6 to move vertically upward under the cooperation of the threaded structures between the adjacent first threaded rods 4, so that the abutting seat 6 can abut against the air conditioning unit body 1 and lift it by a certain height, and after replacing the support seat 18, the abutting seat 6 can move vertically downward to lower the height of the air conditioning unit body 1 by reversely rotating one of the first threaded rods 4.

[0035] Please refer to Figures 1-9The translation component includes two openings 14 communicated with one side of the rod groove 3, a positioning rod 16 penetratingly and slidingly arranged at one end of the first threaded rod 4 located at the adjacent position on the surface of the threaded sleeve 5, and a second threaded rod 15 penetratingly and threadedly arranged at one end of the positioning rod 16 located at the adjacent position on the surface of the threaded sleeve 5. The second threaded rod 15 is slidingly connected with the positioning rod 16, and one side of the second threaded rod 15 is rotationally connected with the abutting seat 6 located at the adjacent position. One side of the positioning rod 16 is fixed with the abutting seat 6 located at the adjacent position.

[0036] When it is necessary to lift the air conditioning unit body 1, the second threaded rod 15 is rotated. Since the positioning rod 16 can limit the abutting seat 6, the abutting seat 6 can only slide in the horizontal direction. Therefore, when the second threaded rod 15 is rotated, the abutting seat 6 located at the adjacent position can slide in the horizontal direction under the cooperation of the threaded structure of the threaded sleeve 5 and the connection of the abutting seat 6, so as to abut against the surface of the bottom of the air conditioning unit body 1. Therefore, when the threaded sleeve 5 drives the abutting seat 6 located at the adjacent position to move vertically upward, the air conditioning unit body 1 can move in the vertical direction. When the first threaded rod 4 is reversely rotated to make the air conditioning unit body 1 move vertically downward, so that the bottom of the air conditioning unit body 1 abuts against the spring shock absorber 19 and the damper 20, the second threaded rod 15 can be reversely rotated to make the abutting seats 6 located at the bottom of the air conditioning unit body 1 move away from the air conditioning unit body 1, so as to ensure that the vibration of the air conditioning unit body 1 can be fully damped by the spring shock absorber 19.

[0037] Please refer to Figures 1-9 The rotating component includes a belt pulley 11 fixedly sleeved on the first threaded rod 4 extending out of the noise reduction shell 2, and a connecting belt 12 arranged at the intermediate position between the two belt pulleys 11 on the top of the same noise reduction shell 2.

[0038] When one of the first threaded rods 4 is rotated, the abutting seat 6 located at the adjacent position can be driven to rotate, so that the two first threaded rods 4 located at the top of the same noise reduction shell 2 can be synchronously and synchronously rotated under the connection of the connecting belt 12.

[0039] Please refer to Figures 1-9 The rotating component further includes two rotating rods 8 rotationally connected to the top of the noise reduction shell 2, a tapered gear 10 fixedly sleeved on the outer circumferential surface of the two first threaded rods 4 located at the bottom of the belt pulley 11 and the outer circumferential surface of the rotating rod 8, a connecting column 9 fixed to one side of one of the rotating rods 8, and a rectangular slot 13 opened on one side of the other rotating rod 8. The two adjacent tapered gears 10 are meshingly connected, and the connecting column 9 is slidingly connected with the rectangular slot 13.

[0040] When the fixed sleeve located at the top of one of the noise reduction shells 2 is rotated, the first threaded rod 4 provided with the pulley 11 and the pulley 11 can rotate the rotating rod 8 under the meshing action between the two adjacent bevel gears 10, so that the two rotating rods 8 can rotate synchronously under the abutting action of the connecting column 9 and the inner wall of the rectangular groove 13, and the first threaded rod 4 located at the top of the two different noise reduction shells 2 can rotate in opposite directions under the meshing action between the other two bevel gears 10.

[0041] Embodiment 2

[0042] Referring to Figures 1-6 As shown, the noise reduction replacement mechanism further comprises a positioning assembly, which comprises a plurality of fixed rings 21 uniformly fixed to the bottom of the air conditioning unit body 1, two inner grooves 24 opened in the inner circumferential surface of the fixed ring 21, movable rods 25 slidingly inserted into the two sides of the fixed ring 21, magnetic attraction grooves 22 opened in the outer circumferential surface of the adjacent position of the spring shock absorber 19 and the damper 20, magnetic attraction blocks 23 arranged in the magnetic attraction grooves 22, movable rods 25 slidingly inserted into the positions on both sides of the fixed ring 21, a fixed disc 26 fixed to the side of the two movable rods 25 away from each other, and a connecting spring 27 sleeved on the outer circumferential surface of the movable rod 25, one side of the connecting spring 27 being fixed to the surface of the adjacent fixed ring 21, the other side of the connecting spring 27 being fixed to the surface of the adjacent fixed disc 26, and the side of the movable rod 25 close to each other being fixed to the surface of the adjacent magnetic attraction block 23;

[0043] When the air conditioning unit body 1 moves vertically downward, the surface of the magnetic attraction block 23 will abut against the top surface of the spring shock absorber 19 and the damper 20, so that the magnetic attraction block 23 is forced to drive the adjacent movable rod 25 to slide outwardly of the fixed ring 21, so that the magnetic attraction block 23 moves to the inner cavity of the adjacent inner groove 24, so as to stretch the adjacent connecting spring 27 to deform, so that when the surface of the bottom of the air conditioning unit body 1 abuts against the top surface of the damper 20 and the spring shock absorber 19, the magnetic attraction groove 22 can move to a position at the same horizontal level as the adjacent magnetic attraction block 23, so as to enable the magnetic attraction block 23 to be embedded in the inner part of the adjacent magnetic attraction groove 22 under the elastic force of the connecting spring 27, so as to limit the movable rod 25 under the magnetic attraction between the magnetic attraction block 23 and the magnetic attraction groove 22, so as to improve the connection relationship between the air conditioning unit body 1 and the spring shock absorber 19 and the damper 20, so as to ensure that the air conditioning unit body 1 has stable shock absorption and noise reduction effect.
