The specific setting method is to connect the elastic vibration-damping pad with a connection hole to the base of the compressor by bolts. However, when performing the connection operation, the installer generally places the elastic vibration-damping pad on the installation platform first, then inserts the bolt from the bottom of the elastic vibration-damping pad into the connection hole, and then uses a finger to extend into the connection hole from the bottom of the elastic vibration-damping pad and fix the bolt to ensure that the bolt does not fall due to its own gravity, and then uses the other hand to connect the nut with the bolt, thereby achieving the connection of the elastic vibration-damping pad with the connection hole to the base of the compressor by bolts.

[0004] However, the above connection operation requires the installer to manually fasten the bolts, which makes the connection operation inconvenient and further reduces the connection efficiency of the elastic vibration damping pad. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0038] Figure 1 is a schematic structural diagram of a vibration reduction device provided in an embodiment of the present application, Figure 2 yes Figure 1 A cross-sectional view of the vibration damping pad formed by cutting along a plane passing through the axis of the connecting hole.

[0039] See also Figure 1 and Figure 2 The vibration reduction device comprises: a vibration reduction pad and a connecting piece. The vibration reduction pad is provided with a connecting hole, and a stop structure is provided on the inner wall of the connecting hole. The connecting piece comprises a clamping structure, the connecting piece is inserted into the connecting hole, and the clamping structure is detachably fixedly connected to the stop structure.

[0040] In the embodiment of the present application, the vibration damping pad is provided with a connection hole, and the connection piece is inserted into the connection hole. The connection piece can be connected to the base of the vibration mechanism, so the vibration damping pad can be connected to the bottom of the vibration mechanism through the connection piece. The vibration damping pad has elasticity, so the vibration damping pad can reduce the transmission effect of the vibration of the vibration mechanism, thereby reducing noise.

[0041] Next, since the inner wall of the connection hole is provided with a stop structure, the connection piece includes a clamping structure, and the clamping structure and the stop structure are detachably fixedly connected. In this way, when the connection piece is inserted into the connection hole and the clamping structure is fixedly connected with the stop structure, the connection piece can be temporarily fixed in the connection hole so that the connection piece will not fall due to its own gravity. Therefore, when the vibration damping device is connected to the base of the vibration mechanism, the installer does not need to manually fix the connection piece, thereby making the connection operation more convenient, so the connection efficiency of the vibration damping device can be improved.

[0042] In addition, since the clamping structure and the stop structure are detachably fixedly connected, the connecting piece and the vibration-damping pad of the vibration-damping device can be disassembled, and the connecting piece and the vibration-damping pad are separated and then packaged. Compared with directly packaging the connected vibration-damping device, the package volume after packaging is reduced, so it is more convenient to transport and store.

[0043] Among them, the above-mentioned vibration damping pad is a polymer elastic vibration damping pad, which can undergo a large deformation when subjected to external force, and can quickly return to its original shape after the external force is removed. It is made of polymer elastic material. The polymer elastic material is a polymer chain structure formed by a large number of repeating units connected by covalent bonds. It has a high elastic modulus and can resist the compression, stretching or shearing of external forces within a certain range and maintain a small deformation. Secondly, it has strong elastic recovery ability. When the external force is removed, the polymer elastic material can quickly return to its original shape and has excellent elastic recovery ability. In addition, it also has good wear resistance and weather resistance, so the vibration damping pad has a long service life. The polymer elastic material can be a thermoplastic elastomer, vulcanized rubber or elastic fiber, which is not limited in the embodiments of the present application.

[0044] In order to prevent the vibration damping pad from being easily damaged during use or installation, the plane corners of the vibration damping pad are chamfered, which can prevent the plane corners of the vibration damping pad from being easily damaged, thereby extending the service life of the vibration damping pad, and thus extending the service life of the vibration damping device.

[0045] It should be noted that the above-mentioned connecting member can be a bolt, a clamp, or other connecting members with the same function, which is not limited in the embodiments of the present application. The material of the connecting member can be metal, plastic, or other materials with the same function, which is not limited in the embodiments of the present application.

[0046] It should also be noted that the sizes of the aforementioned stop structure and the snap-on structure are adapted to each other, and when the two are connected together, they can play a role of temporary fixation.

[0047] It should also be noted that the above-mentioned vibration mechanism refers to a device that can generate vibration, which can be a compressor or vibrator of an air conditioner, or other devices with the same effect, and the embodiments of the present application do not limit this.

[0048] See also Figure 1 , Figure 2 and Figure 7 , when the vibration damping device is connected to the base of the vibration mechanism. First, the connecting piece is directly inserted into the connecting hole of the vibration damping pad and the stop structure on the inner wall of the connecting hole is fixedly connected with the clamping structure of the connecting piece. At this time, the connecting piece is temporarily fixed in the connecting hole; then, the vibration damping pad with the connecting piece is placed on the mounting platform; then, the vibration mechanism is placed on the vibration damping pad; finally, the connecting piece is connected to the base of the vibration mechanism. The above connection operation does not require the installer to manually fix the connecting piece, thereby making the connection operation more convenient, so it can improve the connection efficiency of the vibration damping device.

[0049] In some embodiments, see Figure 1 and Figure 2 The anti-recoil structure includes an anti-recoil groove, which is arranged along the circumference of the connecting hole. The clamping structure includes a clamping protrusion, and the clamping protrusion is adapted to the size of the anti-recoil groove. When the connecting piece is inserted into the connecting hole, the clamping protrusion can be accommodated in the anti-recoil groove, so that the anti-recoil groove will apply a supporting force to the clamping protrusion. Under the action of the supporting force, the clamping protrusion will not fall due to its own gravity, and the clamping protrusion is arranged on the connecting piece, so the connecting piece will not fall due to its own gravity.

[0050] Among them, since the vibration damping pad is elastic, when the connecting piece with the clamping protrusion is inserted into the connecting hole, the clamping protrusion can be smoothly pushed to the position of the anti-recession groove and can be engaged and fixedly connected with the anti-recession groove.

[0051] Next, since the retaining groove is arranged along the circumference of the connecting hole, specifically, the plane where the retaining groove is located is perpendicular to the axis of the connecting hole. In this way, the direction of the supporting force applied by the retaining groove to the clamping protrusion is vertically upward. In this case, the retaining groove and the clamping protrusion are least likely to separate, that is, the connecting piece is least likely to fall off, and the connection between the connecting piece and the vibration damping pad is most firmly made.

[0052] It should be noted that the cross section of the above-mentioned anti-recessing groove can be a rectangular cross section, an arc cross section or a triangular cross section, or a cross section of other shapes, which is not limited in the embodiments of the present application. When the cross section of the anti-recessing groove is a rectangular cross section, the anti-recessing groove is most firmly connected to the clamping protrusion, so the connection between the connecting piece and the vibration damping pad is also most firmly connected.

[0053] In some embodiments, see Figure 1 and Figure 2 , the stop groove is closed along the circumference of the connecting hole. That is, the stop groove is a closed annular stop groove. In this way, the annular stop groove can apply a supporting force to the clamping protrusion at all positions along the circumference of the connecting hole, that is, the force is evenly applied to each position of the clamping protrusion along the circumference of the connecting hole, so that the stop groove and the clamping protrusion can be connected more firmly.

[0054] In addition, the annular anti-recessing groove is more convenient to process than anti-recessing grooves of other shapes, so the production efficiency of the vibration damping pad can be improved.

[0055] In some embodiments, see Figure 1 and Figure 2 The connecting member includes a bolt, and the clamping structure includes a washer, which can be clamped in the stop groove. The washer is a part of the clamping protrusion. Since the bolt is connected by cooperating with the nut, it can meet the requirements of the above connection operation. The specific connection operation process is:

[0056] First, the bolt is directly inserted into the connection hole of the vibration damping pad and the stop groove on the inner wall of the connection hole is fixedly connected with the washer of the bolt. At this time, the bolt is temporarily fixed in the connection hole; then, the vibration damping pad with the bolt is placed on the mounting platform; then, the vibration mechanism is placed on the vibration damping pad; finally, the bolt is connected to the base of the vibration mechanism and the nut is installed. The above connection operation does not require the installer to manually fix the connection parts, which makes the connection operation more convenient, so it can improve the connection efficiency of the vibration damping device.

[0057] Next, since the gasket is an annular sheet body, when the gasket is engaged with the backstop groove, the gasket at each position along the circumference of the connecting hole can be supported by the backstop groove, that is, each position of the circumferential engaging protrusion along the connecting hole is subjected to uniform force, so the backstop groove and the engaging protrusion can be more firmly connected.

[0058] It should be noted that the above-mentioned bolts are polygonal bolts, and specifically can be hexagonal bolts.

[0059] It should also be noted that the material of the gasket can be metal, plastic, or other materials with the same function, and the embodiments of the present application are not limited to this.

[0060] In some embodiments, see Figure 2 and Figure 3The bolt is an expansion bolt. The clamping structure of the expansion bolt is arranged in the middle of the expansion bolt. Since the expansion bolt can be fixedly connected to the base and has a large pull-out resistance, after the bolt is set as an expansion bolt, the vibration reduction device can be fixedly connected to the base, so that the vibration reduction device will not produce a large displacement due to external vibration, and thus can avoid safety accidents caused by the large displacement of the vibration mechanism.

[0061] Among them, the above-mentioned expansion bolt is a special threaded connector, and its working principle is: using the wedge slope to promote expansion to generate friction gripping force to achieve a fixing effect. When the nut is tightened, the bolt moves outward, and the axial movement of the thread causes the conical part to move, thereby forming a large positive pressure on the outer circumference of the expansion tube. In addition, the angle of the cone is very small, so that friction self-locking is formed between the wall, the expansion tube and the cone, thereby achieving a fixing effect. The installation method is: first, use a suitable drill bit to drill a hole of the corresponding size on the fixed body, then install the bolt and expansion tube into the hole, and tighten the nut. As the nut is tightened, the bolt and expansion tube will expand in the hole, thereby achieving fixation.

[0062] It should be noted that the above-mentioned base can be a building structure platform, an equipment foundation, or other fixed basic structure, and the embodiments of the present application do not limit this.

[0063] See also Figure 1 , Figure 2 and Figure 7 , when the above-mentioned base is a building structure platform, the vibration reduction device is connected to the base of the vibration mechanism. First, use an electric drill to drill a mounting hole on the building structure platform, and then use a hammer to knock the expansion bolt into the mounting hole. Next, the connection hole of the vibration reduction pad is sleeved on the exposed end of the expansion bolt and the clamping structure is fixedly connected to the stop structure. Then, the vibration mechanism is placed on the vibration reduction pad; finally, the connecting piece is connected to the base of the vibration mechanism. In this way, the vibration reduction device can be fixedly connected to the building structure platform, so that the vibration reduction device will not produce a large displacement due to external vibration, and safety accidents caused by large displacement of the vibration mechanism can be avoided.

[0064] When the vibration mechanism is connected to the bottom of the air-conditioning compressor, it can prevent the compressor from making a large displacement, thereby preventing the compressor from tipping over or falling, thereby avoiding safety hazards.

[0065] It should be noted that the above-mentioned building structure platform can be an air-conditioning support plate, a canopy, a roof or the ground, or it can be other building structures with the same function, and the embodiments of the present application do not limit this.

[0066] In some embodiments, see Figure 1 and Figure 2 One end of the connecting hole includes a clamping section, an inner wall of the clamping section is provided with a stop structure, and the cross-section of the clamping section gradually increases along the axis of the clamping section toward the surface direction of the vibration damping pad.

[0067] In the embodiment of the present application, the clamping section can be used to transport the clamping structure of the connector to the stop structure, and the dimension of the clamping structure in the direction perpendicular to the axis of the connector is larger than the dimension of the clamping section at the stop structure. However, since the vibration damping pad is elastic, it can be deformed under the extrusion of the clamping structure, so that the clamping structure can be transported to the position of the stop structure in the clamping section. Then, the cross-section of the clamping section gradually increases along the axis of the clamping section toward the surface direction of the vibration damping pad. In this way, before the clamping structure is transported to the stop structure, the stop structure will not be subject to the resistance of the clamping section, and then no thrust is required before the clamping structure is transported to the stop structure, so the connection operation can be simpler and the connection efficiency of the vibration damping device can be improved.

[0068] It should be noted that the cross section of the above-mentioned clamping section may be increased uniformly or unevenly, and this embodiment of the present application does not limit this. When the cross section of the clamping section increases uniformly, the cross section of the clamping section is a trapezoid.

[0069] In some embodiments, see Figure 1 and Figure 2 The cross section of the clamping section is a circular cross section, and the clamping structure is also circular. When the connector with the clamping structure is inserted into the section, the connector will not be affected by its insertion into the clamping section after rotating around its own axis. Compared with setting the cross section of the clamping section to other shapes, setting the cross section of the clamping section to a circular cross section is more convenient for the connection operation.

[0070] In order to make the horizontal displacement of the vibration reduction device smaller when it is subjected to vibration. Figure 1 , Figure 4 and Figure 5 The surface of the vibration damping pad is provided with anti-skid protrusions, and the anti-skid protrusions are used to contact the base.

[0071] In the embodiment of the present application, since the surface of the vibration damping pad is provided with anti-skid protrusions, the roughness of the surface of the vibration damping pad is increased. According to the principle of friction generation, the magnitude of the friction is proportional to the roughness of the contact surface. This increases the friction between the vibration damping pad and the base, thereby enabling the vibration damping device to reduce its horizontal displacement after being subjected to vibration. When the vibration damping device is provided on the base of the vibration mechanism, it can reduce the horizontal displacement of the vibration mechanism.

[0072] The anti-skid protrusion is used to increase the friction between the surface and the contact object to prevent relative sliding, and specifically to achieve the purpose of anti-skid by increasing the friction coefficient between the surface and the contact object. The anti-skid protrusion can be formed in one step when the vibration damping pad is produced, or it can be bonded to the vibration damping pad, which is not limited in the embodiments of the present application.

[0073] When the vibration reduction device is arranged on the base of the compressor of the air conditioner, the displacement of the compressor in the horizontal direction can be reduced, thereby avoiding the occurrence of safety accidents such as the compressor tipping over or falling, thereby improving the safety of the air conditioner.

[0074] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The anti-skid protrusion is a strip-shaped protrusion, the cross section of the strip-shaped protrusion is a trapezoid, and the longer bottom side of the trapezoid is connected to the surface of the vibration damping pad.

[0075] After simulation experiment analysis, when the anti-skid protrusions are arranged according to the above scheme, the friction coefficient of the contact surface can be made larger while ensuring the flatness of the contact surface. That is, when the same vibration is applied to the vibration damping device, the corresponding friction force is larger when the anti-skid protrusions are arranged according to the above scheme, thereby making the horizontal displacement of the vibration damping device smaller. Among them, when the direction of the above strip protrusions is perpendicular to the vibration direction, the friction force is the largest.

[0076] It should be noted that the strip-shaped protrusions are formed at one time when the vibration damping pad is produced.

[0077] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The range of the angle α between the hypotenuse of the trapezoid and the surface of the vibration damping pad is 45°≤α≤65°, and the range of the height h of the trapezoid is 1mm≤h≤1.5mm. The trapezoid is an isosceles trapezoid, and the range of the angle α between the two hypotenuses of the isosceles trapezoid and the surface of the vibration damping pad is 45°≤α≤65°.

[0078] After simulation experiment analysis, when the size of the anti-skid protrusion with a trapezoidal cross section is set according to the above scheme, the friction coefficient of the contact surface can be maximized. That is, when the same vibration is applied to the vibration damping device, the corresponding friction force is maximized when the anti-skid protrusion is set according to the above scheme, thereby minimizing the horizontal displacement of the vibration damping device.

[0079] In some embodiments, see Figure 1 and Figure 2The vibration reduction device also includes a supporting member, which is detachably connected to the vibration reduction pad through a connecting member, and the supporting member is used to support the vibration mechanism. The contact area between the supporting member and the base of the vibration mechanism is large, so that the supporting member can evenly receive the vibration of the vibration mechanism. In addition, the contact area between the supporting member and the vibration reduction pad is also large, so that the supporting member can evenly transfer the received vibration to the vibration reduction pad, so that the vibration reduction pad deforms more evenly, which can extend the service life of the vibration reduction pad.

[0080] In some embodiments, see Figure 1 and Figure 2 The supporting member includes a plurality of supporting strips, and both ends of each supporting strip are respectively connected to the vibration-damping pad.

[0081] In the embodiment of the present application, since the supporting member includes a plurality of support strips, the contact area between the base of the vibration mechanism and the supporting member will be further increased, and the vibration of the vibration mechanism can be more evenly transmitted to the supporting member. Then, since the two ends of each support strip are respectively connected to the vibration damping pad, on the one hand, the contact area between the supporting member and the vibration damping pad is increased, so that the supporting member can evenly transmit the received vibration to the vibration damping pad, so that the deformation of the vibration damping pad is more uniform, and at the same time, the pressure between the supporting member and the vibration damping pad is reduced, so that the service life of the vibration damping pad can be extended. On the other hand, each support strip and the two vibration damping pads can form a simply supported beam structure, and the simply supported beam structure is more stable than other structures, so the vibration damping device is more stable.

[0082] It should be noted that the above-mentioned support strips can be metal strips, plastic steel strips, or strips made of other high-strength materials, which are not limited in the embodiments of the present application. The support strips can be rectangular support strips, elliptical support strips, or support strips of other shapes, which are not limited in the embodiments of the present application.

[0083] In order to connect the support strip and the vibration damping pad through the connecting piece, fixing holes are respectively provided at both ends of the support strip, and the fixing holes can cooperate with the connecting hole plates of the vibration damping pad, and the support strip and the vibration damping pad are connected through the connecting piece.

[0084] See also Figure 1 , Figure 2 and Figure 7When the connecting member is a bolt, and the vibration damping device is set on the base of the vibration mechanism, first, the bolt is directly inserted into the connection hole of the vibration damping pad and the stop groove on the inner wall of the connection hole is fixedly connected with the washer of the bolt. At this time, the bolt is temporarily fixed in the connection hole; then, the vibration damping pad with the bolt is placed on the installation platform; then the fixing hole of the support plate is aligned with the connection hole of the vibration damping pad and the nut is installed on the bolt, so that the installation of the vibration damping device is completed. Then, the vibration mechanism is placed on the vibration damping device. On the one hand, the above-mentioned vibration damping device increases the contact area between the supporting member and the vibration damping pad, so that the supporting member can evenly transfer the received vibration to the vibration damping pad, so that the deformation of the vibration damping pad is more uniform, and at the same time, the pressure between the supporting member and the vibration damping pad is reduced, thereby extending the service life of the vibration damping pad. On the other hand, each support plate bar and two vibration damping pads can form a simply supported beam structure, and the simply supported beam structure is more stable than other structures, so the vibration damping device is more stable.

[0085] It should be noted that the above-mentioned fixing hole can be a circular hole, a rectangular hole, or a connecting hole of other shapes, which is not limited in the embodiments of the present application.

[0086] In order to prevent the vibration mechanism from sliding relative to the support bar after being placed on the support bar, a footing is provided on the upper part of the support bar, the surface of the footing is made of anti-slip material, and the footing protrudes from the upper surface of the support bar. In this way, when the vibration mechanism is placed on the support bar, the footing can increase the friction between the vibration mechanism and the support bar, thereby preventing the vibration mechanism from sliding relative to the support bar, and further reducing the horizontal displacement of the vibration mechanism.

[0087] It should be noted that the above-mentioned anti-skid material refers to a material that can increase the surface friction coefficient, which can be a rubber anti-skid material, a polyurethane anti-skid material, a ceramic anti-skid material or a quartz sand anti-skid material, and the present application embodiment does not limit this. When the surface of the base foot is rubber, a layer of rubber sheet is closely attached to the upper surface of the base foot.

[0088] An embodiment of the present application also discloses an air conditioner, which includes any one of the vibration reduction devices described above.

[0089] The vibration damping device is arranged at the bottom of the compressor of the air conditioner. In this way, when the vibration damping device is connected to the base of the compressor. First, the connecting piece is directly inserted into the connecting hole of the vibration damping pad and the retaining structure of the inner wall of the connecting hole is fixedly connected with the clamping structure of the connecting piece. At this time, the connecting piece is temporarily fixed in the connecting hole; then, the vibration damping pad with the connecting piece is placed on the installation platform; then, the compressor is placed on the vibration damping pad; finally, the connecting piece is connected to the base of the compressor. The above connection operation does not require the installer to manually fix the connecting piece, thereby making the connection operation more convenient, so the connection efficiency of the vibration damping device can be improved.

[0090] When the connecting member includes a bolt and the clamping structure includes a washer, the washer can be clamped in the anti-recession groove. When performing the connection operation, firstly, the bolt is directly inserted into the connection hole of the vibration damping pad and the anti-recession groove on the inner wall of the connection hole is fixedly connected with the washer of the bolt. At this time, the bolt is temporarily fixed in the connection hole; then, the vibration damping pad with the bolt is placed on the mounting platform; then, the compressor is placed on the vibration damping pad; finally, the bolt is connected to the base of the compressor and the nut is installed. The above connection operation does not require the installer to manually fix the connecting member, thereby making the connection operation more convenient, so the connection efficiency of the vibration damping device can be improved. Since the washer is an annular sheet body, when the washer is clamped in the anti-recession groove, the washer at each position along the circumference of the connection hole can be supported by the anti-recession groove, that is, each position of the clamping protrusion along the circumference of the connection hole is evenly stressed, so the anti-recession groove and the clamping protrusion can be connected more firmly.

[0091] When the bolt is an expansion bolt, the clamping structure of the expansion bolt is arranged in the middle of the expansion bolt. Since the expansion bolt can be fixedly connected to the base and has a large pull-out resistance, after the bolt is set as an expansion bolt, the vibration reduction device can be fixedly connected to the base, so that the vibration reduction device will not produce a large displacement due to external vibration, and thus safety accidents caused by large displacement of the compressor can be avoided.

[0092] When the compressor of the air conditioner needs to be set on the building structure platform. First, use an electric drill to drill a mounting hole on the building structure platform, and then use a hammer to knock the expansion bolt into the mounting hole. Next, the connection hole of the vibration damping pad is set on the exposed end of the expansion bolt and the clamping structure is fixedly connected to the stop structure. Then, place it on the vibration damping pad. Finally, connect the connecting piece to the base. In this way, the vibration damping device can be fixedly connected to the building structure platform, so that the vibration damping device will not produce a large displacement due to external vibration, and the compressor can be prevented from having a large displacement, thereby preventing the compressor from tipping over or falling, thereby avoiding safety hazards.

[0093] It should be noted that the above-mentioned building structure platform can be an air-conditioning support plate, a canopy, a roof or the ground, or it can be other building structures with the same function, and the embodiments of the present application do not limit this.

[0094] When the surface of the vibration damping pad is provided with anti-skid protrusions, the roughness of the surface of the vibration damping pad can be increased. According to the principle of friction generation, the magnitude of the friction force is proportional to the roughness of the contact surface. This increases the friction between the vibration damping pad and the base, thereby enabling the vibration damping device to reduce its horizontal displacement after being subjected to vibration. When the vibration damping device is provided at the base of the compressor, it can reduce the horizontal displacement of the compressor. When the vibration damping device is provided at the base of the compressor of the air conditioner, it can reduce the horizontal displacement of the compressor, thereby avoiding safety accidents such as the compressor tipping over or the compressor falling, thereby improving the safety of the air conditioner.

[0095] When the vibration reduction device includes a supporting member, the supporting member is detachably connected to the vibration reduction pad through a connecting member, and the supporting member is used to support the compressor. The contact area between the supporting member and the base of the compressor is large, so that the supporting member can evenly receive the vibration of the compressor. In addition, the contact area between the supporting member and the vibration reduction pad is also large, so that the supporting member can evenly transfer the received vibration to the vibration reduction pad, so that the vibration reduction pad deforms more evenly, which can extend the service life of the vibration reduction pad.

[0096] When the above-mentioned supporting member includes a plurality of support strips, the contact area between the base of the compressor and the supporting member will be further increased, and the vibration of the compressor can be more evenly transmitted to the supporting member. Then, since the two ends of each support strip are respectively connected to the vibration-damping pad, on the one hand, the contact area between the supporting member and the vibration-damping pad is increased, so that the supporting member can evenly transmit the received vibration to the vibration-damping pad, so that the deformation of the vibration-damping pad is more uniform, and at the same time, the pressure between the supporting member and the vibration-damping pad is reduced, so that the service life of the vibration-damping pad can be extended. On the other hand, each support strip and the two vibration-damping pads can form a simply supported beam structure, and the simply supported beam structure is more stable than other structures, so the vibration-damping device is more stable, and the horizontal displacement caused by the compressor's own vibration can be reduced.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
