To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

A vibration damping structure 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the vibration reduction structure 100 according to the embodiment of the present invention is used for a compressor 300 of an air conditioner 1000. The vibration damping structure 100 according to the embodiment of the present invention is not limited to be applied to vibration damping of the compressor 300 of the air conditioner 1000, and may be applied to any device requiring vibration damping between two members. In addition, it should be noted that the type of the air conditioner 1000 to which the vibration damping structure 100 according to the embodiment of the present invention is applied is not limited, and for example, the vibration damping structure may be applied to an air conditioner all-in-one machine, such as a mobile air conditioner, a window air conditioner, and the like, and may also be applied to an indoor unit of a split air conditioner, such as an air conditioner on-hook, a cabinet air conditioner, and the like.

For simplicity of description, only the application of the vibration damping structure 100 according to the embodiment of the present invention to the mobile air conditioner 1000 is described as an example, and after a person skilled in the art reads the technical solutions described below, it is obvious that the vibration damping structure 100 according to the embodiment of the present invention is applied to other specific embodiments of equipment that needs vibration damping, and details are not described herein. As shown in fig. 1 to 3, the air conditioner 1000 includes a base plate 200 and a compressor 300 disposed on the base plate 200, and the vibration damping structure 100 is disposed between the base plate 200 and the compressor 300.

Therefore, when the compressor 300 vibrates during operation, the vibration damping structure 100 can better attenuate vibration energy during transmission from the compressor 300 to the base plate 200, so that the transmission of vibration energy to the base plate 200 can be better weakened, the vibration of the air conditioner 1000 caused by the compressor 300 can be reduced, and the reduction of vibration noise of the air conditioner 1000 is facilitated. In addition, along with the attenuation of vibration energy, the vibration amplitude of the compressor 300 and the air conditioner 1000 is reduced, so that the breakage of a connecting pipeline caused by the overlarge vibration amplitude of the compressor 300 or the air conditioner 1000 can be better avoided, the impact force on the mounting platform of the air conditioner 1000 is reduced, and the reliability and the stability of the air conditioner 1000 are improved.

Specifically, as shown in fig. 3 to 5, the vibration damping structure 100 includes: a connecting piece 1 and a damping piece 2. Wherein, the connector 1 is inserted through the bottom plate 200 of the air conditioner 1000 and the mounting foot 310 of the compressor 300 to connect the compressor 300 to the bottom plate 200. That is, the compressor 300 is provided with a mounting foot 310 for engaging with the connector 1, and the mounting foot 310 is fitted to the outer peripheral side of the connector 1. Therefore, the assembly difficulty of the compressor 300 mounted on the base plate 200 can be well reduced, the connection stability of the compressor 300 and the base plate 200 can be well ensured, and the reliability and the stability of the air conditioner 1000 can be improved.

Further, the vibration damper 2 is fitted around the outer peripheral side of the link 1. That is to say, the vibration damping member 2 is inserted into the mounting foot 310, and at least a part of the vibration damping member 2 is located between the mounting foot 310 and the connecting member 1, that is, the mounting foot 310 is not in direct contact with the connecting member 1, therefore, when the compressor 300 vibrates, the vibration damping member 2 can better avoid the mounting foot 310 from being in direct contact with the connecting member 1, so that vibration energy can be prevented from being transmitted to the base plate 200 through the connecting member 1 without attenuation, and then vibration of the air conditioner 1000 caused by the compressor 300 can be reduced, which is beneficial to reducing vibration noise of the air conditioner 1000. In addition, the fracture of a connecting pipeline caused by the overlarge vibration amplitude of the compressor 300 or the air conditioner 1000 can be better avoided, the impact force on the mounting platform of the air conditioner 1000 is reduced, and the improvement of the reliability and the stability of the air conditioner 1000 is facilitated.

Furthermore, at least part of the damping element 2 is located between the mounting foot 310 and the chassis 200. Therefore, when the compressor 300 vibrates and tends to move towards the base plate 200, the vibration damping member 2 can better buffer the vibration of the compressor 300 in the axial direction, so that the vibration energy can be better weakened to be transmitted to the base plate 200 through the vibration damping member 2, the vibration of the air conditioner 1000 caused by the compressor 300 can be reduced, the vibration noise of the air conditioner 1000 can be favorably reduced, and the reliability and the stability of the air conditioner 1000 can be improved.

Referring to fig. 5 and 6, the portion of the outer circumferential wall of the connecting member 1, which is opposite to the damping member 2, is a fitting portion 120, a first groove 123 is formed in the fitting portion 120, and a deformation space 3, in which the damping member 2 can elastically deform, is defined between the damping member 2 and the inner wall surface of the first groove 123. That is, at least a portion of the fitting portion 120 is disposed apart from the vibration damping member 2, so that undamped transmission of vibration energy due to direct contact between the vibration damping member 2 and the connection member 1 can be avoided.

In addition, when the vibration energy of the compressor 300 is transmitted to the vibration damping member 2, the vibration damping member 2 may be deformed toward the deformation space 3, and it can be understood that the vibration energy may be well attenuated during the compression deformation of the vibration damping member 2. From this, the elastic deformation volume that deformation space 3 can be better promotes damping piece 2 to can promote the damping performance of damping piece 2, promptly, promote damping piece 2 to the damping performance of vibration energy, thereby can further weaken the vibration energy and transmit to chassis 200, and then can reduce the air conditioner 1000 vibration because of compressor 300 leads to, do benefit to the vibration noise that reduces air conditioner 1000, and promote the reliability and the stability of air conditioner 1000.

In addition, through locating first recess 123 on connecting piece 1, compare in setting up the recess that is used for deformation on damping piece 2, can better avoid influencing damping piece 2's structural strength. That is, the amount of elastic deformability of the damper 2 is increased while the damping performance of the damper 2 itself is ensured.

According to the vibration damping structure 100 of the embodiment of the utility model, the first groove 123 is formed on the matching portion 120, and the deformation space 3 for elastic deformation of the vibration damping member 2 is defined between the vibration damping member 2 and the inner wall surface of the first groove 123, compared with the case that the groove for elastic deformation is arranged on the vibration damping member 2, the vibration damping performance of the vibration damping member 2 is ensured, and meanwhile, the elastic deformable amount of the vibration damping member 2 is increased, and the damping performance of the vibration damping member 2 on vibration energy is improved, so that the transmission of the vibration energy to the chassis 200 can be further weakened, the vibration of the air conditioner 1000 caused by the compressor 300 can be reduced, the vibration noise of the air conditioner 1000 can be reduced, and the reliability and stability of the air conditioner 1000 can be improved.

In a specific example of the present invention, referring to fig. 1 and 3, the compressor 300 has three mounting feet 310, and the three mounting feet 310 are uniformly spaced along the outer peripheral wall of the compressor 300, that is, the compressor 300 may be connected to the base plate 200 through the three vibration damping structures 100, so as to further enhance the vibration damping effect of the vibration damping structures 100 on the compressor 300, and further weaken the transmission of vibration energy to the base plate 200, further reduce the vibration of the air conditioner 1000 caused by the compressor 300, facilitate reducing the vibration noise of the air conditioner 1000, and enhance the reliability and stability of the air conditioner 1000.

According to some embodiments of the utility model, as shown in fig. 7-9, the first groove 123 extends in the axial direction of the connection piece 1 and is annular. That is, the inner wall surface of the first groove 123 may define, together with the damper 2, the deformation space 3 extending in the circumferential direction of the attachment 1. From this, can better increase the elastic deformation volume of damping piece 2 in the radial direction of connecting piece 1 for in the circumferential direction of connecting piece 1, damping piece 2 can be towards the range promotion that takes place elastic deformation in deformation space 3, with the decay performance of promotion damping piece 2 to the vibration energy, thereby can further weaken the vibration energy and transmit to chassis 200, and then can reduce the air conditioner 1000 vibration because of compressor 300 leads to.

Alternatively, as shown in fig. 6, the upper wall surface of the first groove 123 is lower than the upper end surface of the damper 2, and the lower wall surface of the first groove 123 is substantially flush with the lower end surface of the damper 2. That is, the upper end surface of the vibration damping member 2 is higher than the first groove 123, the lower end of the vibration damping member 2 is lower than the first groove 123, and the height of the vibration damping member 2 is greater than the extension length of the first groove 123 in the up-down direction, so that the vibration damping member 2 can better cover the first groove 123.

Alternatively, a portion of the inner peripheral wall of the damper 2 opposite to the first groove 123 is formed with a second groove 21. Therefore, at the position of the second groove 21, the distance between the connecting member 1 and the vibration damping member 2, that is, the distance between the first groove 123 and the opposite side wall of the second groove 21, is increased, so that the size of the deformation space 3 can be further increased, the elastic deformable amount of the vibration damping member 2 at the position of the second groove 21 can be further increased, the transmission of vibration energy to the chassis 200 can be further weakened, the vibration of the air conditioner 1000 caused by the compressor 300 can be further reduced, the reduction of the vibration noise of the air conditioner 1000 is facilitated, and the reliability and stability of the air conditioner 1000 are improved. In addition, when the deformation space 3 is lifted, the influence on the structural strength of the connecting piece 1 can be avoided, so that the connecting piece 1 is ensured to meet the strength requirement of the air conditioner 1000 on the connecting piece 1.

Wherein the second groove 21 extends in the circumferential direction of the damping part 2 and is annular. Therefore, the elastic deformation amount of the vibration damping member 2 in the radial direction of the connecting member 1 can be further increased, that is, in the circumferential direction of the connecting member 1, the vibration damping member 2 can be increased toward the amplitude of the elastic deformation in the deformation space 3, so as to improve the damping performance of the vibration damping member 2 on the vibration energy, and further reduce the transmission of the vibration energy to the chassis 200, thereby reducing the vibration of the air conditioner 1000 caused by the compressor 300.

Further alternatively, the second recess 21 is located in an upper part of the damping member 2. That is, the second groove 21 is disposed adjacent to the upper end surface of the damper 2 compared to the lower end surface of the damper 2. It should be noted that the position of the second groove 21 in the up-down direction of the damping member 2 can be flexibly set according to the structural requirement, and is not limited specifically here.

In a specific example, the second recess 21 may be provided according to the connection position of the mounting foot 310 with the damping member 2. As shown in fig. 6, the mounting foot 310 is mounted on the upper portion of the damping member 2, i.e. the mounting foot 310 is arranged adjacent to the upper end face of the damping member 2 compared to the lower end face of the damping member 2. It will be appreciated that, when the compressor 300 vibrates, since the compressor 300 is connected to the vibration reduction structure 100 through the mounting feet 310, that is, vibration energy is transmitted to the vibration reduction member 2 through the mounting feet 310, the vibration reduction member 2 is subjected to a large amount of vibration energy at the position where the mounting feet 310 are connected. Thus, by disposing the second groove 21 on the upper portion of the inner circumferential surface of the vibration damping member 2, the height position of the second groove 21 can be substantially the same as the mounting height position of the mounting foot 310, and the larger deformation space 3 formed by the second groove 21 can better attenuate the vibration energy at the mounting foot 310 position, so as to further weaken the transmission of the vibration energy to the chassis 200.

Certainly, the mounting feet 310 can be arranged at the middle position of the damping member 2 in the height direction, the mounting feet 310 can also be arranged at the lower position of the damping member 2 in the height direction, no specific limitation is made here, and in the height direction of the damping member 2, the height position of the second groove 21 is approximately the same as the mounting height of the mounting feet 310, so as to ensure that the deformation space 3 for elastic deformation of the damping member 2 is defined by the first groove 123 and the second groove 21, and the vibration energy of the mounting feet 310 can be buffered, and the damping effect is good.

Further optionally, the axial height of the second groove 21 is smaller than the axial height of the first groove 123, and/or the depth of the second groove 21 is smaller than the depth of the first groove 123. The axial height here refers to the extension of the first groove 123 and the second groove 21 in the axial direction of the connection piece 1, and the depth here refers to the extension of the first groove 123 and the second groove 21 in the radial direction of the connection piece 1. Wherein only the axial height of the second groove 21 may be set smaller than the axial height of the first groove 123; or only the depth of the second groove 21 is set to be smaller than the depth of the first groove 123; or the axial height of the second groove 21 is smaller than the axial height of the first groove 123 and the depth of the second groove 21 is smaller than the depth of the first groove 123.

It will be understood that the greater the axial height and the greater the depth of the second recess 21, the greater the deformation space 3 which can be defined between the damping part 2 and the connection part 1, with a consequent increase in the structural strength of the damping part 2 itself. From this, the axial height of second recess 21 is less than the axial height of first recess 123, and/or the degree of depth of second recess 21 is less than the degree of depth of first recess 123, guarantees that second recess 21 can promote deformation space 3 to when promoting damping piece 2 elastic deformation volume, can avoid better causing the influence because of the axial height of second recess 21 or the great structural strength to damping piece 2 of degree of depth numerical value, does benefit to the structural strength who guarantees damping piece 2.

Further alternatively, a third groove 22 is formed in a portion of the inner circumferential wall of the vibration damping member 2 opposite to the first groove 123, the third groove 22 extends in an annular shape along the axial direction of the vibration damping member 2, the third groove 22 is located below the second groove 21, and the third groove 22 penetrates through the lower end surface of the vibration damping member 2 downward. As shown in fig. 6, the lower end surface of the damping member 2 may be fitted to the chassis 200, so that the inner wall surface of the third groove 22 may define the deformation space 3 together with the attachment 1 and the chassis 200. Thus, the distance between the upper inner wall surface in the third groove and the chassis 200 can be increased to a high degree by the amount of elastic deformation of the damper 2 in the axial direction. It can be understood that, in the up-down direction, the mounting foot 310 is connected with the chassis 200 through the vibration damping member 2, so that the vibration damping member 2 can better weaken the vibration in the up-down direction of the mounting foot 310, and can weaken the direct transmission of the vibration to the chassis 200 through the vibration damping member 2, and further can reduce the vibration of the air conditioner 1000 caused by the compressor 300, thereby being beneficial to reducing the vibration noise of the air conditioner 1000, and improving the reliability and stability of the air conditioner 1000.

Wherein the depth of the third groove 22 is greater than the depth of the second groove 21 and greater than the depth of the first groove 123. That is, in the radial direction of the joint 1, the extension length of the third groove 22 is greater than the extension length of the second groove 21 and greater than the extension length of the first groove 123. Thereby, the deformation space 3 defined between the third groove 22 and the attachment 1 and the chassis 200 is made large, facilitating to increase the amount of elastic deformability of the damper 2. In addition, the contact area between the lower end surface of the vibration damper 2 and the chassis 200 can be reduced, so that the vibration energy non-attenuation transmission caused by the contact between the vibration damper 2 and the chassis 200 can be avoided, the vibration of the air conditioner 1000 caused by the compressor 300 can be reduced, the vibration noise of the air conditioner 1000 can be reduced, and the reliability and the stability of the air conditioner 1000 can be improved.

Further alternatively, the damping member 2 may be provided with a fourth recess 23 on the outer circumferential wall thereof, and at least a portion of the mounting foot 310 may be received in the fourth recess 23. The mounting foot 310 can be completely accommodated in the fourth groove 23, so as to increase the contact area between the mounting foot 310 and the vibration damping member 2, which not only can improve the connection strength between the mounting foot 310 and the vibration damping member 2, but also can ensure that the vibration energy of the compressor 300 can be stably transmitted to the vibration damping member 2 through the mounting foot 310 for buffering; or a portion of the mounting foot 310 is received in the fourth recess 23 to reduce the difficulty of assembling the mounting foot 310 with the damping member 2.

From this, through setting up fourth recess 23, can be better damping piece 2 installs the location degree of difficulty to installation footing 310 to, through fourth recess 23 to installation footing 310 spacing, can promote the stability of being connected of installation footing 310 and compressor 300 better, promptly, avoid damping piece 2 to drop from installation footing 310, so that damping piece 2 can continuously stably attenuate the vibration energy of compressor 300.

Wherein at least a part of the fourth groove 23 is diametrically opposite to the second groove 21. Wherein, the fourth groove 23 may be completely opposite to the second groove 21 in the radial direction; or a part of the fourth groove 23 is disposed diametrically opposite to the second groove 21.

It can be understood that, when the compressor 300 vibrates, since the compressor 300 is connected to the vibration damping structure 100 through the mounting foot 310, that is, vibration energy is transmitted to the vibration damping member 2 through the mounting foot 310, the vibration damping member 2 is subjected to larger vibration energy at the position where the mounting foot 310 is connected, and the deformation space 3 defined between the inner wall surface of the first groove 123 and the inner wall surface of the second groove 21 together is larger, so that the vibration damping member 2 has a larger deformation space 3 at the position of the second groove 21, that is, the connecting position of the vibration damping member 2 and the mounting foot 310 has a larger elastic deformation amount.

Therefore, when the mounting feet 310 have radial vibration relative to the connecting piece 1, the mounting feet 310 can extrude the vibration damping piece 2 to have large elastic deformation amount towards the connecting piece 1, so that the vibration damping piece 2 gradually attenuates the vibration energy transmitted by the mounting feet 310 in the deformation process, and then the vibration of the chassis 200 caused after the vibration energy is transmitted to the connecting piece 1 through the vibration damping piece 2 can be weakened, thereby being beneficial to reducing the vibration noise of the air conditioner 1000, and improving the reliability and stability of the air conditioner 1000.

According to some embodiments of the utility model, with reference to fig. 7-9, the connector 1 comprises: a threaded section 11, a smooth section 12 and a fixed section 13. Specifically, the smooth section 12 is connected to the axial lower side of the threaded section 11, the damping member 2 is sleeved on the smooth section 12, and at least a part of the outer peripheral wall of the smooth section 12 forms the fitting portion 120. That is, the upper end of the smooth section 12 is connected to the lower end of the threaded section 11, and the first groove 123 is formed on the smooth section 12. It will be appreciated that the threaded segment 11 may be better fitted with a nut or the like. For example, the connecting member 1 may be installed on the chassis 200, and after the vibration damping member 2 is sleeved on the connecting member 1, the freedom of movement of the vibration damping member 2 may be limited from the upper side by the cooperation of the nut and the threaded section 11, so that the vibration damping member 2 may be prevented from being separated from the connecting member 1, and the stability of connection between the vibration damping member 2 and the chassis 200 may be ensured.

In addition, through setting up level and smooth section 12, can reduce the production degree of difficulty of connecting piece 1 better, simultaneously for the frictional force of damping piece 2 and connecting piece 1 is little, does benefit to the assembly degree of difficulty that reduces damping piece 2.

Wherein, the fixed section 13 is connected to the axial lower side of the smooth section 12, and the fixed section 13 is connected with the chassis 200. That is, the fixing section 13 is provided on a side of the smooth section 12 away from the threaded section 11. Therefore, the fixed connection between the connecting member 1 and the chassis 200 can be better ensured through the fixing section 13, so that the stability of the vibration damping member 2 and the chassis 200 can be improved, the vibration damping member 2 can continuously damp the vibration of the compressor 300, and the transmission of the vibration energy of the compressor 300 to the chassis 200 is weakened.

Further, the smooth section 12 includes a first smooth section 121 and a second smooth section 122. Specifically, the first smooth section 121 is connected to the threaded section 11, the outer peripheral surface of the first smooth section 121 is in contact with the inner peripheral surface of the damper 2, the second smooth section 122 is connected between the first smooth section 121 and the fixed section 13, the diameter of the second smooth section 122 is smaller than that of the first smooth section 121, and the first smooth section 121, the second smooth section 122 and the fixed section 13 together define a groove.

That is, the first smooth section 121 is connected to the lower end of the threaded section 11, the second smooth section 122 is connected to the lower end of the first smooth section 121, the fixing section 13 is connected to the lower end of the second smooth section 122, the first smooth section 121 is located on the upper side of the second smooth section 122, the first smooth section 121 is attached to the inner circumferential surface of the damper 2, and the second smooth section 122 is spaced apart from the inner circumferential surface of the damper 2. This prevents undamped transmission of vibration energy due to direct contact between the damping part 2 and the connecting part 1. Moreover, the first smooth section 121 is attached to the vibration damping member 2, so that the communication between the external space and the deformation space 3 can be better prevented, dirt such as dust in the external environment cannot enter the deformation space 3, and the stability of the vibration damping structure 100 is improved.

In addition, the outer circumferential surface of the first smooth section 121 is smooth, so that the friction between the outer circumferential surface of the first smooth section 121 and the inner circumferential surface of the vibration damping member 2 is small, and the vibration damping member 2 can slide relative to the first smooth section 121 when elastically deformed in the axial direction, thereby attenuating vibration energy in the elastic deformation process.

Further, the diameter a of the first smooth section 121 and the diameter b of the second smooth section 122 satisfy: b/a is more than or equal to 0.7 and less than or equal to 0.9, and/or the length c of the second smooth section 122 and the length d of the smooth section 12 satisfy: c/d is more than or equal to 0.7 and less than 1. Specifically, 0.7. ltoreq. b/a. ltoreq.0.9 may be satisfied; or only satisfies 0.7 ≤ c/d < 1; or b/a is more than or equal to 0.7 and less than or equal to 0.9, and c/d is more than or equal to 0.7 and less than 1.

Specifically, the diameter ratio of the second smooth section 122 to the first smooth section 121 is controlled to be between 0.7 and 0.9, for example, the diameter ratio of the second smooth section 122 to the first smooth section 121 may be 0.7, 0.75, 0.8, 0.85, 0.9, etc. It is understood that, when the diameter of the first smooth section 121 is the same, the smaller the ratio of the diameters of the second smooth section 122 to the first smooth section 121, the larger the depth value of the first groove 123, i.e. the larger the deformation space 3 that the damping member 2 can define with the connection member 1, the larger the amount of elastic deformation of the damping member 2 towards the inside of the deformation space 3, but the influence on the structural strength of the connection member 1 is increased. Therefore, by controlling the diameter ratio of the second smooth section 122 to the first smooth section 121 to be 0.7 to 0.9, the elastic deformable quantity of the damping piece 2 can be improved better while the structural strength of the connecting piece 1 is prevented from being influenced by the overlarge depth of the second smooth section 122, which is beneficial to improving the damping performance of the damping structure 100.

Furthermore, in the axial direction of the connecting piece 1, the length c of the second smooth section 122 and the length d of the smooth section 12 satisfy: c/d is more than or equal to 0.7 and less than 1. That is, the axial height ratio of the second smooth segment 122 to the smooth segment 12 is controlled to be between 0.7 and 1, and does not include 1, for example, the axial height ratio of the second smooth segment 122 to the first smooth segment 121 may be 0.7, 0.75, 0.8, 0.85, 0.9, and the like. It can be understood that, when the axial lengths of the smooth sections 12 are the same, the smaller the ratio of the axial heights of the second smooth section 122 to the smooth section 12 is, the larger the value of the axial height of the first groove 123 is, so that the deformation space 3 which can be defined by the damping piece 2 and the connecting piece 1 is, the larger the elastic deformable amount of the damping piece 2 towards the deformation space 3 is, but the influence on the structural strength of the connecting piece 1 is increased; in addition, the larger the axial height value of the second smooth section 122 is, the smaller the axial height value of the first smooth section 121 is, so that the contact area between the vibration damping member 2 and the smooth section 12 can be better reduced, and the vibration energy can be better reduced to be transmitted to the connecting member 1 through the joint position between the first smooth section 121 and the vibration damping member 2.

Therefore, when the structural strength of the vibration damping member 2 is prevented from being influenced by the excessive axial height of the second smooth section 122, the elastic deformable amount of the vibration damping member 2 can be better improved, and meanwhile, the contact area between the vibration damping member 2 and the smooth section 12 can be reduced, which is beneficial to improving the vibration damping performance of the vibration damping structure 100.

Further, referring to fig. 7 to 9, the outer circumferential wall of the fixing section 13 is formed with a concavo-convex structure. Therefore, the friction between the fixing section 13 and the chassis 200 can be increased, and the position of the connecting member 1 can be further limited. In a concrete example, concave-convex structure is equipped with a plurality ofly, and concave-convex structure extends along the axial direction of canned paragraph 13, forms the annular knurl structure on canned paragraph 13's periphery wall promptly, from this, can promote frictional force between canned paragraph 13 and the chassis 200 better, can prevent simultaneously that canned paragraph 13 from rotating relatively the chassis 200, promptly, prevents that connecting piece 1 from rotating relatively the chassis 200 to can avoid connecting piece 1 to rock the abnormal sound that causes, do benefit to the structural stability who promotes air conditioner 1000.

Specifically, the outer diameter of the threaded section 11 is 6mm, the diameter of the first smooth section 121 is the same as the outer diameter of the threaded section 11, the axial height is 3mm, the diameter of the second smooth section 122 is 5mm, the error is ± 0.1mm, the axial length is 19mm, the outer diameter of the knurled section 131 is 6.7mm, the axial length is 9mm, and the outer diameter of the nut 132 is larger than the outer diameter of the knurled section 131.
