[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see the appendix Figure 1 -Appendix Figure 6 This utility model discloses an MPP bellows with a quick connector, comprising two fastening rings 1, each with a second fastening ring 2 on one side. A rotating shaft 3 is rotatably connected to the inner sides of both fastening rings 1 and 2. One end of a coil spring 5 is connected to the outer side of one end of the rotating shaft 3. The other end of the right coil spring 5 is connected to the inner wall of the fastening ring 1, and the other end of the left coil spring 5 is connected to the inner wall of the second fastening ring 2. A sleeve 4 is connected to the middle of the outer side of the rotating shaft 3. The outer side of the sleeve 4... A connecting block 6 is connected to the side, a blocking block 7 is connected to the outer side of the connecting block 6, a rubber pad 8 is connected to one side of the blocking block 7, a protruding ring 9 is connected to the side of the second fastening ring 2 near the first fastening ring 1, one end of a plurality of telescopic columns 10 is connected to the middle of the inside of the protruding ring 9, a spring 11 is provided on the outer side of the telescopic column 10, and a snap ring 12 is connected to the other end of the telescopic column 10, a limit ring 13 is slidably connected inside the side of the first fastening ring 1 near the second fastening ring 2, and the limit ring 13 and the snap ring 12 are set accordingly.

[0025] In the first embodiment, the top of the snap ring 12 near the fastening ring 1 is arc-shaped, and the fastening ring 1 is provided with a slot that matches the convex ring 9 on the side near the fastening ring 2. One end of the spring 11 is connected to the inner wall of the convex ring 9, and the other end of the spring 11 is connected to the outer wall of the snap ring 12. The multiple blocking blocks 7 are all inclined, and the inclination directions of the multiple blocking blocks 7 on the left and right sides are opposite.

[0026] Specifically, through the cooperation of the snap-fit ​​ring 12 and the limiting ring 13, when fastening ring 1 and fastening ring 2 are spliced, fastening ring 2 only needs to be pressed tightly against fastening ring 1. At this time, the protruding ring 9 on fastening ring 2 enters into fastening ring 1, and the snap-fit ​​ring 12 on the protruding ring 9 squeezes the limiting ring 13, causing the limiting ring 13 to move upward. The snap-fit ​​ring 12 occupies the original position of the limiting ring 13, thus completing the snap-fit ​​fixation. Through the inclined setting of the blocking block 7, the end of the bellows connection is blocked by the inclined blocking block 7 after passing through the fastening ring, so it cannot be pulled out, thereby achieving the fixation of the bellows.

[0027] In embodiment 2, extension blocks 14 are connected to both the front and rear sides of the two fastening rings 1 and 2. The two extension blocks 14 on the same side are connected by bolts 15. The bottom end of the bolts 15 passes through the middle of the interior of the two extension blocks 14, and a nut 16 is threaded to the outer side of the bottom end of the bolts 15.

[0028] Specifically, the distance between the two fastening rings 1 and 2 is adjustable through the combination of extension block 14, bolt 15 and nut 16. The distance between the two fastening rings 1 and 2 is also adjustable. At this time, it can be adjusted according to the diameter of the bellows, so as to adapt to different models of bellows and improve the applicability of the device.

[0029] Working principle:

[0030] In use, first adjust according to the model of the bellows to be connected, that is, loosen it by rotating nut 16, thereby changing the distance between the two fastening rings 1 and 2. The same applies to fastening ring 2. Adjust according to the diameter of the bellows. After completion, pass one end of the bellows through fastening ring 1 and fastening ring 2 respectively. Due to the inclined setting of the blocking block 7, the end of the bellows connected is blocked by the inclined blocking block 7 after passing through the fastening rings, thus preventing it from being pulled out, thereby fixing the bellows and allowing passage. Through the cooperation of the snap-fit ​​ring 12 and the limiting ring 13, when fastening ring 1 and fastening ring 2 are spliced, fastening ring 2 only needs to be pressed tightly against fastening ring 1. At this time, the protruding ring 9 on fastening ring 2 enters into fastening ring 1. The snap-fit ​​ring 12 on the protruding ring 9 squeezes the limiting ring 13, causing the limiting ring 13 to move upward. The snap-fit ​​ring 12 occupies the original position of the limiting ring 13, completing the snap-fit ​​fixation. When disassembling, simply press the limiting ring 13 and squeeze the snap-fit ​​ring 12 to separate fastening ring 1 and fastening ring 2. Thus, the entire process is completed.
