[0002] The air conditioning compressor of a car is an indispensable part of the car's refrigeration system. With the trend of lightweight upgrades, the material of the compressor bracket has also been improved from cast iron bracket to cast aluminum bracket. When installing the air conditioning compressor, the torque directly acts on the air conditioning compressor body. At the same time, since the strength of aluminum is weaker than cast iron, the compressor installation angle will be deformed, and the air conditioning bracket will be crushed. Finally, during the long-term operation of the air conditioning compressor, the compressor will leak refrigerant and fail. Utility Model Content

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

[0027] The utility model provides an adjustment sleeve and an air-conditioning compressor installation structure based on the adjustment sleeve. Figure 4 As shown, the air-conditioning compressor mounting structure includes an air-conditioning compressor 2 provided with at least two lifting ear structures 21, a bracket 3 provided with a lifting ear mounting tube 31, a fixing bolt 4 and an adjustment sleeve for fixing the lifting ear structure 21 to the lifting ear mounting tube 31. The number of the adjustment sleeves is adjusted according to the number of the lifting ear structures 21.

[0028] Specifically, the adjustment sleeve includes a sleeve 11 with openings at both ends and a gasket 12 fixed outside one end of the sleeve 11 and perpendicular to the axis of the sleeve 11 .

[0029] The adjustment sleeve can be implemented in a variety of structures, exemplary of which are:

[0030] Example 1: Reference Figure 1 The gasket 12 is annular and fixed on the outer diameter surface of one end of the sleeve 11.

[0031] Example 2: Reference Figure 2 The gasket 12 is in sheet form and is also fixed on the outer diameter surface of one end of the sleeve 11. Only one gasket 12 may be provided, or multiple gaskets 12 may be provided at the same time, such as 2, 4 or 4. When a gasket of sheet structure is used, preferably at least two are provided.

[0032] Example 3: Reference Figure 3 , an adjustment opening 13 is provided on the side wall of the sleeve 11. At this time, the gasket can be used Figure 1 The gasket 12 is provided with a notch structure 14 connected to the adjustment opening 13, which is integrated into the Figure 3 As shown. The gasket can also be used Figure 2 For the sheet structure shown, at this time, it is only necessary to adjust the opening 13 to communicate with the gap between two adjacent gaskets.

[0033] The adjustment sleeve needs to be sleeved on the screw rod during installation and installed in the installation hole of the ear structure 21. When the structures of Examples 1 and 2 are adopted, the processing accuracy of the sleeve 11 is required to be high. In order to facilitate installation and better adaptability, the structure in Example 3 is preferably adopted.

[0034] When the air-conditioning compressor 2 is installed by using an adjustment sleeve of any of the above structures, the sleeve 11 is sleeved on the fixing bolt and the gasket 12 is placed between the ear mounting tube 31 and the ear structure 21 . The length of the sleeve 11 is greater than the thickness of the ear structure 21 .

[0035] It should be noted that the thickness referred to here is the length of the mounting hole of the hanging ear structure 21, that is, the axial length of the mounting hole.

[0036] Since the length of the sleeve 11 is greater than the thickness of the ear structure 21, there is a certain gap between the nut of the fixing bolt and the ear structure 21 of the air-conditioning compressor 2, and the fixing bolt does not directly apply force to the ear structure 21 of the air-conditioning compressor 1 on the clamping plane. By setting the adjustment sleeve, the situation of crushing the air-conditioning bracket is effectively improved, and at the same time, the adjustment sleeve is stressed, and the installation angle of the air-conditioning compressor will not be deformed due to the stress, which effectively avoids the compressor leakage and failure due to deformation of the installation angle.

[0037] Specifically, when the air-conditioning compressor is installed, an adjustment sleeve can be provided on the fixing bolt corresponding to each ear structure 21. In order to reduce costs and facilitate installation, the adjustment sleeve can be provided only on the fixing bolt corresponding to the ear structure 21 on one side of the air-conditioning compressor.

[0038] For example, refer to Figures 4 to 8 There are four ear structures 21 of the corresponding type of air-conditioning compressor, and the four ear structures 21 are respectively arranged at the four corners of the air-conditioning compressor 2, and the corresponding bracket structure is as follows: Fig. 9 As shown. The adjusting sleeve is sleeved on the fixing bolts corresponding to the two hanging ear structures 21 on the same side. Figure 6 In the embodiment, the fixing bolts of the two hanging ear structures 21 on the left are sleeved with adjustment sleeves; the fixing bolts of the two hanging ear structures 21 on the right are not sleeved with adjustment sleeves, that is, they are directly fixed by fixing bolts, maintaining the same structure as the existing structure.

[0039] Of course, an adjustment sleeve may also be provided on the fixing bolt corresponding to each lifting ear structure 21. In this case, Figure 6 If point C is replaced with point B, it will be axially symmetrical.

[0040] By adopting the above structure, when installing the air-conditioning compressor 2, the adjustment sleeve will shift forward when subjected to force, and when the adjustment sleeve contacts the bracket, it plays an adjusting and tightening role. At the same time, the cross-section of the adjustment sleeve is a T-shaped structure, that is, the setting of the gasket 12 increases the bearing surface area of ​​the contact cast aluminum bracket, effectively improving the situation of crushing the air-conditioning bracket; at the same time, when the adjustment sleeve is subjected to force, the installation angle of the compressor will not be deformed due to the force, effectively avoiding the leakage and failure of the compressor due to deformation of the installation angle.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
