For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0024] See also Figure 1-Figure 8 A combined air-conditioning unit comprises a unit case 1, and vents 2 are installed at both ends of the left and right ends of the unit case 1. The interior of the unit case 1 is sequentially installed with primary and secondary efficiency filter segments 3, cooling and heating segments 4, windmill segments 5, punching air dispersion plates 6, and high-efficiency filters 7 from the air inlet to the air outlet. A connecting seat 8 is fixedly connected to the bottom end of the unit case 1, and a shock-absorbing base 9 is installed at the lower end of the connecting seat 8. A plurality of fastening bolts 10 are installed between the connecting seat 8 and the shock-absorbing base 9.

[0025] During the use of this solution, in order to solve the problem that some manufacturers fail to fully consider the actual situation and needs during the design, resulting in product defects or inapplicability, such as: there is a certain correlation between the various modules of the combined air-conditioning unit. If one of the modules fails or has problems, the entire system may be affected. In addition, due to the combined installation method, its maintenance and maintenance are more difficult. If the shock absorber fastening bolts are loose or the spring is broken, or the belt slips, etc., the combined air-conditioning unit may generate loud noise during operation, affecting the quietness of the indoor environment. In this embodiment, each module of the combined air-conditioning unit is installed in a sliding and pulling manner, so that when the combined air-conditioning unit needs to be maintained and repaired, it is only necessary to open the cabinet door and then pull out each module one by one to perform the maintenance operation, which greatly improves the maintenance efficiency and convenience of the combined air-conditioning unit. Meanwhile, in this embodiment, by changing the structure of the existing shock absorber and the fastening bolts, the bolts of the combined air-conditioning unit are not easily loosened or broken to cause vibrations during long-term operation of the combined air-conditioning unit, thereby reducing the shaking between the equipment and the noise generated; And under the action of the shock-absorbing base 9, the shock-absorbing efficiency of the combined air-conditioning unit can be further realized, avoiding the generation of loud noise during operation, ensuring the quietness of the indoor environment, and reducing the problem of damage to some equipment of the combined air-conditioning unit due to vibration.

[0026] See also Figure 1-Figure 4 The shock absorbing base 9 includes a shock absorbing box 91 provided on the bottom side of the connecting seat 8, the upper end of the shock absorbing box 91 is provided with two symmetrically distributed grooves 92, the lower end of the groove 92 is provided with a groove 2 93, a partition 94 is fixedly connected to the inner bottom end of the groove 2 93, a stress reduction member 95 is installed between the inner walls of the partition 94, the lower end of the stress reduction member 95 is fixedly connected to a shock absorbing gasket 96, the shock absorbing gasket 96 is located between the inner walls of the groove 2 93, the side end of the stress reduction member 95 is fixedly connected to a limiting sleeve 97, the side wall of the groove 1 92 is fixedly connected to a capsule 98, and the outer end of the capsule 98 is installed with a spring steel plate 99.

[0027] More specifically: the stress reduction member 95 includes a connecting platform 951 provided between the inner walls of the partition 94, the bottom end of the connecting platform 951 is fixedly connected to the top end of the shock-absorbing gasket 96, the side end of the connecting platform 951 is fixedly connected to the limiting sleeve 97, the outer end of the connecting platform 951 is provided with a connecting sleeve 952, the connecting sleeve 952 is located on the upper side of the limiting sleeve 97, the upper end of the connecting platform 951 is provided with a stress reduction groove 953, the inner walls of the stress reduction groove 953 are movably connected with a top plate 954, and the top plate 954 is fixedly connected to the connecting seat 8.

[0028] During use of this solution, the combined air-conditioning unit is placed on the surface of the connecting seat 8 by the action of the fastening bolts 10, and then the combined air-conditioning unit is less likely to vibrate greatly during operation under the damping action of the damping base 9, thereby reducing component loss and noise caused by vibration. When in use, after the combined air-conditioning unit runs on the surface of the connecting seat 8, the vibration force it generates is first reduced by the vibration force generated by the back and forth offset of the top plate 954 between the inner walls of the stress reduction groove 953, and as the connecting platform 951 drives the limit sleeve 97 to impact the surface of the spring steel plate 99, the impact force is then weakened under the elastic potential energy of the spring steel plate 99 and the capsule 98, and during the vibration amplitude, the shock-absorbing gasket 96 is simultaneously displaced inside the groove 2 93, thereby reducing the vibration force generated during the overall operation of the combined air-conditioning unit, reducing the noise caused by vibration and the wear of some equipment, greatly ensuring the stability of the combined air-conditioning unit during operation, and at the same time ensuring the quietness of the indoor environment.

[0029] See also Figure 1-Figure 2 and Figure 5-Figure 8 The fastening bolt 10 includes a stud 101 that penetrates into a plurality of through holes on the surface of the connecting seat 8 and the shock-absorbing base 9.

[0030] More specifically: the stud 101 includes a pad 1011, a column 1012, a connecting end 1013, and a threaded end 1017. The pad 1011 is fixedly connected to the column 1012, the connecting end 1013 is fixedly connected to the upper side of the column 1012, the threaded end 1017 is fixedly connected to the upper side of the connecting end 1013, and the side end of the connecting end 1013 is provided with a plurality of evenly distributed receiving grooves 1014, one side end of the receiving groove 1014 is fixedly connected to a spring sheet 1015, and the other side end of the receiving groove 1014 is rotatably connected to a limiting block 1016, one side of the limiting block 1016 is located on the outer surface of the spring sheet 1015, and the upper end of the connecting end 1013 is fixedly connected to the threaded end 1017.

[0031] More specifically: the nut 102 includes a cap sleeve 1021, and four symmetrically distributed slide grooves 1022 are opened on the upper end of the cap sleeve 1021. A ring 1023 is fixedly connected to the upper end of the cap sleeve 1021. The ring 1023 is located on the outer side of the slide groove 1022. A transmission sleeve 1024 is movably connected between the inner walls of the ring 1023. A limiting member 1025 is installed on the inner wall of the bottom side of the cap sleeve 1021.

[0032] More specifically, the limiting member 1025 includes a plurality of second slide grooves 10251 provided inside the cap sleeve 1021, a third slide groove 10252 is provided on the inner wall of the bottom side of the cap sleeve 1021, the third slide groove 10252 is communicated with the second slide groove 10251, a limiting column 10253 is provided between the inner walls of the third slide groove 10252, and two symmetrically distributed fourth slide grooves 1025 are provided on the side wall of the third slide groove 10252. 4. The left and right ends of the limit column 10253 are fixedly connected with sliders 10255, the slider 10255 is located between the inner walls of the fourth slide groove 10254, and a spring 10256 is fixedly connected between the slider 10255 and the side wall of the fourth slide groove 10254, and a resistance member 10257 is slidably connected between the inner walls of the second slide groove 10251, and the top of the resistance member 10257 is fixedly connected to the transmission sleeve 1024.

[0033] More specifically, a first magnetic block 102531 is embedded and installed at the rear end of the limiting column 10253, and a second magnetic block 102532 is embedded and installed at one side of the bottom of the abutment 10257, and the first magnetic block 102531 and the second magnetic block 102532 are attracted to each other.

[0034] During use of this solution, in order to prevent the bolts from loosening due to vibration between devices after being fixed for a long time, thereby causing excessive shaking and floating between devices, resulting in greater wear and noise, in this embodiment, by changing the structural organization of the original combined air-conditioning unit fastening bolts, the position of the fastening bolts cannot loosen or shift without human control after fastening, thereby ensuring the stability of the combined air-conditioning unit after installation and avoiding vibration and greater noise caused by loose bolts; When in use, the personnel first place the pad 1011 on one side of the device to be fixed, and then pass the threaded end 1017 through the through hole between the two devices to be fixed, and then screw the cap 1021 from the outside of the threaded end 1017. When the cap 1021 is screwed into the contact surface, the limit block 1016 can be rotated clockwise, and the limit column 10253 continues to press the limit block 1016, so that the limit block 1016 presses the spring piece 1015 to be stored in the storage groove 1014 until the two devices are positioned. In the subsequent operation, such as the combined air When the air conditioning unit vibrates during operation, if the cap sleeve 1021 rotates counterclockwise, the limiting column 10253 is always in contact with the surface of the connecting end 1013. When the air conditioning unit rotates counterclockwise, the limiting column 10253 is limited by the protrusion of the limiting block 1016 due to the resilience of the spring sheet 1015 and the surface of the limiting block 1016 rebounding outward, so that the cap sleeve 1021 cannot rebound and loosen, thereby ensuring the stability of the bolts after positioning during operation of the combined air conditioning unit, avoiding loosening during use, resulting in wear of multiple components and generation of large noise; When personnel need to disassemble the device later, they can rotate the transmission sleeve 1024 clockwise to cause 1027 to slide synchronously between the second slide groove 10251, so that the limit column 10253 rebounds under the action of the spring 10256 and is stored between the second slide groove 10251, with one side presenting a horizontal plane with the inner wall of the cap sleeve 1021. At this time, as the cap sleeve 1021 continues to rotate counterclockwise, due to the resistance force on the inner wall of the cap sleeve 1021, the limit block 1016 is subjected to force again to compress the spring piece 1015, so that it is stored in the storage groove 1014, and the bolt can be disassembled, which greatly ensures the stability of the combined air-conditioning unit during operation and avoids the loosening caused by vibration.

[0035] In this example, by embedding a magnet 102531 on one side of the limit column 10253, and embedding a magnet 102532 on the bottom side of the resistance member 10257 that attracts each other, the resistance member 10257 can always be located on the side of the limit column 10253 for resistance during bolt tightening, thereby ensuring the stability of tightening and preventing the upper transmission sleeve 1024 from rotating due to external factors.

[0036] See also Figure 1-Figure 2 A humidifying section 11 is also installed inside the unit housing 1 . The humidifying section 11 is located on one side of the high-efficiency filter 7 , and a water collecting plate 12 is installed below the humidifying section 11 .

[0037] During use of this solution, by installing a water collecting plate 11 on the lower side of the humidifying section 7, the condensed water generated during the humidification operation of the humidifying section 7 can be collected inside the water collecting plate 12 for storage, and finally can be uniformly discharged through the water outlet pipe.

[0038] See also Figure 1-Figure 2 Polyethylene sound insulation pads 13 are installed on both the upper and lower sides of the connecting seat 8.
