[0030] Example 1

[0031] See also Figure 1-4, a suction cup assembly of a clutch of an automobile air-conditioning compressor in an embodiment of the first aspect of the utility model comprises: a suction cup shell 1, and three suction cup outer fixing blocks 11 arranged in a circular array on the outer side of the suction cup shell 1, and a hole-like structure is opened inside the suction cup shell 1, and is adapted to the suction cup inner shell 3, the suction cup inner shell 3 is placed in the middle of the inner side of the suction cup shell 1 and is engaged with the suction cup shell 1, and an inner spline 31 is fixedly arranged in the middle of the upper end surface of the suction cup inner shell 3, and the size of the hole-like structure opened in the middle of the suction cup inner shell 3 corresponds to that opened in the middle of the inner spline 31, and the middle of the suction cup inner shell 3 is opened with three hole-like structures arranged in a circular array, and the inner end of the support sheet 4 is riveted to the upper surface of the suction cup inner shell 3 by the inner ring screw 5, and a sealing shell 2 is placed on the upper surface of the support sheet 4, and the three hole-like structures opened in a circular array on the surface of the sealing shell 2 correspond one-to-one to the hole-like structures on the surface of the suction cup shell 1, and are fixed by the middle ring screw 6. The sealing shell 2, the support sheet 4 and the suction cup shell 1 are riveted in sequence from top to bottom, and the sealing rubber ring 21 inside the sealing shell 2 is tightly attached to the automobile air-conditioning compressor clutch through the middle circle screw 6. At the same time, the sealing rubber ring 21 is made of rubber material. The sealing rubber ring 21 is arranged in a groove opened on the inner side of the upper end of the sealing shell 2, and is pasted in the groove opened on the inner side of the upper end of the sealing shell 2 through strong glue. The currently existing pasting technology can be used by pasting with strong glue, which can provide a better shock-absorbing function for the suction cup overall assembly during use, so that the suction cup assembly can be stably fixed on the required installation position of the automobile air-conditioning compressor clutch through the middle circle screw 6, wherein the hole structures opened on the outer ends of the suction cup shell 1, the sealing shell 2 and the support sheet 4 are all compatible with the middle circle screw 6, and the hole structures opened on the inner ends of the suction cup inner shell 3 and the support sheet 4 are all compatible with the inner circle screw 5, and the installation method can be installed using the existing riveting technology.

[0032] Example 2

[0033] In this example, see Figure 1-5 In the process of installing the suction cup assembly, there may be an externally installed suction cup. Therefore, on the basis of Example 1, after the outer ends of the sealing shell 2 and the support sheet 4 are riveted to the suction cup shell 1 from top to bottom in sequence, they are directly fastened and fixed, and are not riveted together with the automobile air-conditioning compressor clutch. Relatively, the hole structure opened in the middle of the suction cup external fixing block 11 is matched with the outer ring screw 7, and then the outer ring screw 7 is used to fix the suction cup assembly to the position where the automobile air-conditioning compressor clutch needs to be installed. At the same time, the outer ring screw 7 and the automobile air-conditioning compressor clutch are riveted in the existing riveting method.

[0034] For further information, see Figures 1 to 5The above-mentioned riveted hole structure, inner ring screw 5, middle ring screw 6 and outer ring screw 7 can be enlarged or reduced within a controllable range according to actual needs, thereby increasing the sealing degree of the suction cup assembly on the automobile air-conditioning compressor clutch.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
