Detailed implementation manners

[0032] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the implementation manners and the drawings. Here, the illustrative implementation manners of the present application and their descriptions are used to explain the present application, but do not limit the present application.

[0033] Referring to Figures 1 to 6 , as Figure 1 shown, this embodiment provides a compressor fixing assembly, which includes: a connecting bolt 1, a fixing sleeve 41, a retaining ring 42 and a mounting nut 5. The fixing sleeve 41 is sleeved on the connecting bolt 1 to increase the connection area and provide additional support. Its inner diameter matches the outer diameter of the connecting bolt 1 to ensure that it can be firmly sleeved on the bolt. The retaining ring 42 is also sleeved on the connecting bolt 1 and is designed to be able to abut against the fixing sleeve 41. The mounting nut 5 is sleeved on the end of the connecting bolt 1 to lock the retaining ring 42 and the fixing sleeve 41. When the mounting nut 5 is tightened, the retaining ring 42 will apply pressure to the fixing sleeve 41. A rubber gasket 44 is also sleeved on the connecting bolt 1, and the rubber gasket 44 is located at the head of the connecting bolt 1.

[0034] By rotating the mounting nut 5, the locking force on the retaining ring 42 can be adjusted, thereby controlling the tightening degree of the entire fixing assembly.

[0035] Specifically, the connecting bolt 1 includes an integrally connected connecting head 11 and a screw rod part 12. The rubber gasket 44 is connected to the connecting head 11. The fixing sleeve 41, the retaining ring 42 and the mounting nut 5 are sequentially installed on the screw rod part 12, and the mounting nut 5 is located at the end of the screw rod part 12, that is, the position farthest from the connecting head 11.

[0036] AsFigure 2 and Figure 3 As shown in Figure 3 , an annular groove 411 is formed in the fixed sleeve 41, and a plurality of elastic rubber blocks 43 are arranged in the annular groove 411. When the mounting nut 5 locks the retaining ring 42, the retaining ring 42 abuts against the plurality of elastic rubber blocks 43.

[0037] As Figure 2 and Figure 3 As shown in Figure 3 , an annular sleeve 421 is connected to the retaining ring 42, and the annular sleeve 421 can abut against the plurality of elastic rubber blocks 43, thereby realizing the connection between the retaining ring 42 and the fixed sleeve 41.

[0038] In the compressor fixing assembly, the annular groove 411 formed in the fixed sleeve 41, the plurality of elastic rubber blocks 43 arranged therein, and the annular sleeve 421 connected to the retaining ring 42 together constitute a loosening prevention device.

[0039] The annular groove 411 is formed in the fixed sleeve 41, providing a receiving space for the elastic rubber blocks 43. The elastic rubber blocks 43 are arranged in the annular groove 411 and have certain elasticity and compressibility. When subjected to an external force, they can deform and store energy, and then attempt to return to their original shape after the external force is removed.

[0040] The retaining ring 42 is sleeved on the connecting bolt 1 and can abut against the annular groove 411 in the fixed sleeve 41 and the elastic rubber blocks 43 therein. The annular sleeve 421 is connected to the retaining ring 42. When the mounting nut 5 locks the retaining ring 42, the annular sleeve 421 will also tightly abut against the elastic rubber blocks 43.

[0041] Realization of loosening prevention: When the mounting nut 5 is gradually tightened, the retaining ring 42 applies pressure to the elastic rubber blocks 43 through the annular sleeve 421. Due to the compressibility of the elastic rubber blocks 43, these elastic rubber blocks 43 will deform and store energy. As the mounting nut 5 is further tightened, the deformation of the elastic rubber blocks 43 reaches a certain degree. At this time, the reaction force generated by these elastic rubber blocks 43 (i.e., the force attempting to return to the original shape) and the locking force of the mounting nut 5 act together, making the connection between the retaining ring 42 and the fixed sleeve 41 more firm, realizing the effect of loosening prevention. Even under the action of external vibration or impact load, the connection between the retaining ring 42 and the fixed sleeve 41 is not easily loosened. Because the energy stored by the elastic rubber blocks 43 during the deformation process will continuously apply an inward force to the retaining ring 42, thereby resisting the loosening trend.

[0042] As Figure 3As shown, the elastic rubber block 43 includes an upper arm 431, a lower arm 433, and a bending portion 434 connected in sequence. The bending portion 434 is closer to the connecting head 11 than the upper arm 431. The bending portion 434 abuts against the bottom of the annular groove 411, and the annular sleeve 421 abuts against the lower arm 433.

[0043] Preferably, a clamping groove 432 is formed on the side of the upper arm 431 away from the center of the connecting bolt 1. An annular rib 412 extending towards the center is provided on the annular groove 411. The clamping groove 432 is engaged with the annular rib 412. By connecting the clamping groove 432 and the annular rib 412, the elastic rubber block 43 can be firmly fixed in the fixing sleeve 41.

[0044] Preferably, a first inclined surface 4211 is provided on the side of the annular sleeve 421 away from the center of the connecting bolt 1, and a second inclined surface 4331 is provided on the side of the lower arm 433 close to the center of the connecting bolt 1. The second inclined surface 4331 abuts against the first inclined surface 4211.

[0045] As Figure 4 shown, a plurality of compression springs 6 are connected between the fixing sleeve 41 and the retaining ring 42. Specifically, a first counterbore 413 is further formed on the fixing sleeve 41, and a second counterbore 422 is formed on the retaining ring 42. The first counterbore 413 and the second counterbore 422 are arranged opposite to each other, and a plurality of compression springs 6 abut between the first counterbore 413 and the second counterbore 422.

[0046] Among them, a plurality of compression springs 6 are located inside the annular sleeve 421.

[0047] A plurality of compression springs 6 are connected between the fixing sleeve 41 and the retaining ring 42 to provide a continuous pre-tightening force, which helps to maintain the tight connection between the retaining ring 42 and the fixing sleeve 41 and prevent loosening.

[0048] Through the pre-tightening effects of the compression springs 6 and the elastic rubber block 43, this structure achieves multiple anti-loosening functions. Even when subjected to vibration or external forces, it can effectively maintain the connection stability and prevent the components from loosening.

[0049] Refer to Figures 5 to 6 , as Figure 5 shown, this embodiment further provides an air conditioner, including a fixing component, and further including: a compressor 7 and a bottom plate 71. The compressor 7 can be fixed on the bottom plate 71 through the compressor fixing component.

[0050] As Figure 6As shown, feet 72 are provided on the compressor 7. The feet 72 are sleeved on the connecting bolt 1 and can be fixed between the rubber gasket 44 and the fixed sleeve 41. An installation bracket 2 is provided on the bottom plate 71. The installation bracket 2 is sleeved on the connecting bolt 1 and is connected between the rubber gasket 44 and the connecting bolt 1.

[0051] In the embodiment of the present application, the installation bracket 2 includes a top plate 21, a vertical plate 23 and a fixing plate 22 which are integrally connected. The top plate 21 is parallel to the fixing plate 22. The fixing plate 22 is fixed on the bottom plate 71. The vertical plate 23 is vertically connected between the top plate 21 and the fixing plate 22.

[0052] During installation, the top plate 21 is sleeved on the screw part 12, and the top plate 21 is in pressing connection with the connecting head 11. Then, the rubber gasket 44, the feet 72, the fixed sleeve 41 and the retaining ring 42 are sequentially connected to the screw part 12 in order. The elastic rubber block 43 and the compression spring 6 are pre-installed in the fixed sleeve 41. Finally, the installation nut 5 is locked on the screw part 12. As the installation nut 5 is tightened, the retaining ring 42 will squeeze the elastic rubber block 43 and the compression spring 6, so that the elastic rubber block 43 and the compression spring 6 tightly abut against the fixed sleeve 41. And the fixed sleeve 41 will move in the direction close to the connecting head 11 under the extrusion effect, so that the feet 72, the top plate 21 and the rubber gasket 44 tightly abut against the connecting head 11, thus realizing the reliable fixation between the compressor 7 and the bottom plate 71. When the air conditioner jolts during transportation, under the pre-tightening action of the elastic rubber block 43, the compression spring 6 and the rubber gasket 44, the connection between the installation nut 5 and the connecting bolt 1 will not become loose.

[0053] As can be seen from the above, the present application can realize the fixed connection between the compressor 7 and the bottom plate 71, can avoid the situation that the compressor 7 loosens on the bottom plate 71 due to transportation jolts. The fixing component improves the connection stability, and further makes the use safer and more reliable.

[0054] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the embodiments of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
