[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] Reference Figure 1-Figure 5As shown, the automobile air-conditioning clutch pulley 1 which is easy to install in this embodiment comprises a pulley 1 and a bearing 2 arranged on the pulley 1, one end of the pulley 1 is provided with a friction surface 3, and the other end is provided with a receiving groove 4, and the side of the pulley 1 is provided with a groove 11, and the pulley 1 is provided with a mounting groove 5 at one end where the friction surface 3 is provided, and a locking component 6 is provided in the mounting groove 5, and the locking component 6 comprises:

[0027] A movable ring 61 is rotatably disposed in the mounting groove 5;

[0028] The reeds 62 are arranged on the inner side of the movable ring 61 and have a plurality of reeds distributed around the circumference;

[0029] The locking strip 63 is fixedly connected to the inner end of the spring leaf 62 , and the locking strip 63 is arc-shaped.

[0030] Through the above technical solution, when the pulley 1 is installed on the compressor, the coil assembly is first installed on the rotating shaft of the compressor, and then the pulley 1 is installed. During installation, one side of the receiving groove 4 is aligned with the coil assembly, and then the pulley 1 is sleeved on the rotating shaft of the compressor. After sleeved, the spring leaf 62 is pressed outward by hand to move the locking strip 63 outward, and then the pulley 1 slides toward the coil assembly for a certain distance, and the locking strip 63 corresponds to the positioning groove on the rotating shaft of the compressor. Then the spring leaf 62 is released, and the spring leaf 62 is reset to drive the locking strip 63 to embed into the positioning groove to complete the installation; during disassembly, the spring leaf 62 is pressed outward by hand to move the locking strip 63 outward, and then the locking strip 63 is driven to leave the positioning groove on the rotating shaft of the compressor, and then the pulley 1 is removed; installation and disassembly are convenient, and can be operated by hand without special tools. After the installation is completed, since the movable ring 61 is rotatably connected to the installation groove 5, the pulley 1 can rotate alone when the coil assembly is not powered, and the pulley 1 and the movable ring 61 rotate relative to each other. The friction surface 3 is used to combine with the suction cup. A belt is arranged on the groove and connected with the engine. The bearing is sleeved on the rotating shaft of the compressor.

[0031] As an improved specific implementation, there is a gap between the spring leaf 62 and the bottom of the installation groove 5 .

[0032] Through the above technical solution, there is a gap between the reed 62 and the bottom of the installation groove 5, which avoids friction between the reed 62 and the bottom of the installation groove 5 during use, prolongs the service life, and reduces the resistance when the pulley 1 rotates alone.

[0033] As an improved specific implementation, there is a gap between the movable ring 61 and the bottom of the installation groove 5.

[0034] Through the above technical solution, there is a gap between the movable ring 61 and the bottom of the installation groove 5, which avoids friction between the movable ring 61 and the bottom of the installation groove 5 during use, prolongs the service life, and reduces the resistance when the pulley 1 rotates alone.

[0035] As an improved specific embodiment, a locking groove 51 is provided on the side of the mounting groove 5, and the cross-sectional surface of the locking groove 51 is arc-shaped. A rotating groove 611 is provided on the outer side of the movable ring 61, and the cross-sectional surface of the rotating groove 611 is arc-shaped.

[0037] As an improved specific implementation, a reinforcing rib 65 is provided on the spring leaf 62 , and the reinforcing rib 65 connects the spring leaf 62 and the movable ring 61 .

[0038] Through the above technical solution, the reinforcing rib 65 increases the strength of the spring leaf 62, avoids twisting after the pulley 1 is locked, and improves stability during use.

[0039] As an improved specific implementation, the movable ring 61 is composed of a plurality of arc-shaped movable rods 66 , and connecting components 7 are provided between adjacent movable rods 66 .

[0040] Through the above technical solution, a plurality of arc-shaped movable rods 66 form a movable ring 61, which facilitates the movable ring 61 to be installed in the installation groove 5. After installation, adjacent movable rods 66 are connected through the connecting assembly 7.

[0041] As an improved specific implementation, the connecting component 7 includes:

[0042] An upper connecting block 71, wherein an upper connecting hole 711 is provided on the upper connecting block 71;
