The deceleration buffer device 2 can rotate around the buffer device rotating shaft 3 and then contact with the cylinder top rod 4, the flywheel and the flywheel ring gear disk 1 or the door closer spring device 7, and the rotation plane of the deceleration buffer device 2 is parallel to the rotation plane of the flywheel and the flywheel ring gear disk 1.
[0016] In a further embodiment, the utility model further comprises a telescopic adjustment spring 6, referring to Figure 3The base 5 includes a front base and a rear base, and the front base is close to the flywheel and the flywheel ring gear plate 1, and the rear base is far away from the flywheel and the flywheel ring gear plate 1. The telescopic adjustment spring 6 is connected between the front base and the rear base. The cylinder push rod 4, the deceleration buffer device 2 and the door closer spring device 7 are all arranged on the rear base, and the cylinder push rod 4 is located on the rear base near the telescopic adjustment spring 6.
[0017] In a further embodiment, referring to Figure 4 The deceleration buffer device 2 includes a buffer spring 21 and a buffer bearing 22. One end of the buffer spring 21 is connected to the buffer device rotating shaft 3, and the other end is connected to the buffer bearing 22 through a connecting shaft. The outer wall of the buffer bearing 22 is provided with a small tooth 23, and the small tooth 23 can be engaged with the flywheel and the flywheel ring gear plate 1.

[0018] Example
[0019] In this embodiment, a bolt hole is provided on the rear base of the base 5, and the front base is welded to the outer side of the ring gear of the flywheel and the flywheel ring gear plate 1. The length of the telescopic adjustment spring 6 is adjusted according to the diameter of the ring gear, and the rear base is fixed with bolts or welded so that the deceleration buffer device 2 can just engage with the ring gear when it rotates toward the ring gear. Both ends of the buffer device rotating shaft 3 are fixed to the rear base of the base 5, and the middle part can rotate and is connected to one end of the buffer spring 21.
[0020] In the initial state, if Figure 1 As shown, the cylinder top rod 4 extends out, the deceleration buffer device 2 leans against the cylinder top rod 4 and does not contact the ring gear of the flywheel ring gear plate 1. When the engine needs to be decelerated after stopping, the cylinder top rod 4 descends, and the deceleration buffer device 2 approaches the ring gear. Figure 3 As shown, the small teeth 23 thereon mesh with the ring gear;
[0021] At this time, if the gear ring rotates clockwise, the deceleration buffer device 2 is driven inward by the gear ring and breaks away from the gear ring and hits the cylinder top rod 4. Due to the action of the buffer spring 21, the deceleration buffer device 2 is rebounded and collides with the gear ring again and is thrown out by the gear ring. Figure 3 As shown, the deceleration buffer device 2 rotates outward and hits the door closer spring device 7, the door closer spring device 7 is compressed, and then the deceleration buffer device 2 is bounced toward the ring gear, the deceleration buffer device 2 reciprocates and collides and rubs with the ring gear, so that the speed of the flywheel and the flywheel ring gear plate 1 drops rapidly;
[0022] If the ring gear rotates counterclockwise, the deceleration buffer device 2 is driven outward by the ring gear and contacts the door closer spring device 7. Then the door closer spring device 7 rebounds and the deceleration buffer device 2 collides and engages with the ring gear. This process is repeated to rapidly reduce the speed of the flywheel and the flywheel ring gear plate 1. Then the cylinder push rod 4 is extended to separate the deceleration buffer device 2 from the flywheel and the flywheel ring gear plate 1, waiting for the next speed reduction.
[0023] The utility model is provided with a deceleration buffer device 2, which is in continuous contact with the flywheel and the flywheel ring gear plate 1 when the engine is stopped, thereby increasing the movement resistance through collision, thereby accelerating the parking speed and improving the working efficiency, and a buffer spring 21 is provided on the deceleration buffer device 2 to resist the reciprocating impact force.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
