[0024] An embodiment of the present utility model provides a micro-deformation shock-absorbing water pump pulley.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , which includes a pulley body 1. The pulley body 1 can perform pulley transmission to drive the water pump to work. A number of teeth 2 are fixed on the outer circle of the pulley body 1. The teeth 2 can increase the friction and cooperate with the synchronous belt to effectively prevent slipping. Two grooves 3 are opened on the outer side of the middle part of the pulley body 1. The grooves 3 play a role in providing space support for the setting of the fixed disk 8. An installation groove 4 is opened on the inner side of the middle part of the pulley body 1. The installation groove 4 is used for installing on the connecting shaft; A number of slide grooves 5 are opened in the middle of the groove 3. A connecting structure is arranged on the inner wall of each slide groove 5. The connecting structure includes a slide bar 7. A fixed disk 8 is fixed in the middle of each slide bar 7. A first spring 9 is fixed on one side of each fixed disk 8 close to the central axis of the pulley body 1. A second spring 10 is fixed on the other side of each fixed disk 8 away from the central axis of the pulley body 1.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , and it is worth specifically explaining that the outer surface of each slide bar 7 is slidably connected to the inner wall of each slide groove 5. The middle of each fixed disk 8 is fixed to the middle of each slide bar 7. Each fixed disk 8 is arranged in the middle of the groove 3. The cross section of the groove 3 is circular. One end of each first spring 9 is fixed to one side of each fixed disk 8. The other end of each first spring 9 is fixed to the inner wall of the groove 3 close to the central axis of the pulley body 1. One end of each second spring 10 is fixed to the other side of the fixed disk 8. The other end of each second spring 10 is fixed to the inner wall of the groove 3 away from the central axis of the pulley body 1.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, specifically, a sliding block 11 is fixed to one end of each sliding rod 7 away from the central axis of the pulley body 1. The outer surface of each sliding block 11 is slidably connected to the inner wall of each receiving groove 6. Each receiving groove 6 penetrates through one side of the pulley body 1. The vertical section of each sliding block 11 is L-shaped.

[0028] When the present utility model is in use: First, the pulley body 1 rotates under the drive of the connecting shaft, so that the sliding rods 7 sliding on both sides of the pulley body 1 slide in the direction away from the central axis of the pulley body 1 under the action of centrifugal force, so that the fixed disk 8 fixed in the middle of the sliding rod 7 moves synchronously in the direction away from the central axis of the pulley body 1, so that the first spring 9 fixed on the side of the fixed disk 8 close to the central axis of the pulley body 1 is stretched, and the second spring 10 fixed on the side of the fixed disk 8 away from the central axis of the pulley body 1 is compressed, so that both the first spring 9 and the second spring 10 produce micro-deformations, so that both the first spring 9 and the second spring 10 produce elastic forces to support. At this time, the fixed disk 8 is in a stressed state, and when the pulley body 1 rotates smoothly, the fixed disk 8 rotates smoothly synchronously under the action of inertia force driven by the sliding rod 7. When the pulley body 1 vibrates, the impact force generated by the vibration first offsets a part of the elastic forces of the first spring 9 and the second spring 10 that produce micro-deformations. And at this time, the fixed disk 8 rotating smoothly by inertia force provides a reaction force to the first spring 9 and the second spring 10, and further offsets the impact force generated by the vibration, completing the effect of force buffering, weakening the impact force generated by the vibration by inertia force, avoiding the vibration of the pulley affecting the normal operation, and thus achieving the effect of improving the use effect of the pulley. At the same time, the pulley body 1 rotates under the drive of the connecting shaft, so that the sliding rods 7 sliding on both sides of the pulley body 1 slide in the direction away from the central axis of the pulley body 1 under the action of centrifugal force. The sliding rods 7 drive the sliding blocks 11 at one end away from the central axis of the pulley body 1 to slide towards the edge position of the pulley body 1 under the stabilization of the inner wall of the receiving groove 6 until the pulley body 1 runs smoothly. At this time, several sliding blocks 11 all slide out of the receiving groove 6 and are slightly higher than the edge of the pulley body 1 to limit the running synchronous belt, completing the effect of limiting and stabilizing, avoiding the situation that the running synchronous belt deviates or even falls off, and thus achieving the effect of improving the use stability of the pulley.

[0029] Working principle: The pulley body 1 rotates driven by the connecting shaft, so that the sliding rod 7 sliding on the pulley body 1 drives the fixed disk 8 to move, achieving the effect of force buffering, weakening the impact force generated by vibration by relying on inertia force, avoiding the vibration of the pulley from affecting normal operation, and thus achieving the effect of improving the use effect of the pulley. At the same time, the pulley body 1 rotates driven by the connecting shaft, so that the sliding rod 7 sliding on the pulley body 1 drives the sliding block 11 to move, achieving the effect of limit stability, avoiding the deviation or even falling off of the running synchronous belt, and thus achieving the effect of improving the use stability of the pulley.

[0030] Please refer to again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It is worth specifically stating that the installation groove 4 runs through the inner side of the middle part of the pulley body 1, and two grooves 3 are opened on both sides of the pulley body 1. The vertical section of the pulley body 1 is set in an H shape.
