[0006] The rotor is annular, the upper part of the rotor is provided with an outer rotating plate and an inner rotating plate, a cylinder is arranged at the bottom center of the inner tooth seat, the cylinder is inserted into the inner rotating plate, the cylinder is annularly provided with a reinforcing rib, and the reinforcing rib is located between the outer rotating plate and the inner rotating plate.

[0007] The number of the inner rotating plates is three, the number of the reinforcing ribs is four, and the reinforcing ribs are uniformly distributed and connected between the outer rotating plates.

[0008] The bottom of the outer tooth seat is provided with an inner convex ring and an outer convex ring, and the height of the outer convex ring is lower than that of the inner convex ring.

[0009] The outer wall of the rotor is provided with a damping groove.

[0010] The technical scheme of the utility model has novel structure, ingenious design and simple use, the rotor is driven to rotate through the rack, is suitable for more scenes, supplements the vacancy that cannot be used commonly, obtains uniform resistance in the rotating process of the outer rotating plate due to the flow resistance of the damping liquid, and the damping effect is durable and the service life is long; the interval and the gap make the inner rotating plate also produce damping effect with the damping oil, and the resistance is more uniform.

[0018] The utility model will be further described below in combination with the drawings and examples. Example

[0019] As Figure 1 、 2 , 3, 4, 5, 6, 7, 8, 9, 10, 11 rack damper shown, including shell 6 and rotor 1, the shell 6 bottom is equipped with the socket of rack 2 passes through, rack 2 inner wall is equipped with tooth, tooth and gear 7 are engaged, the shell 6 is equipped with outer tooth seat 4, outer tooth seat 4 is equipped with rotor 1, rotor 1 lower end inserts gear 7, rotor 1 is equipped with inner tooth seat 5, and the inner wall of outer tooth seat 4 and rotor 1 are equipped with damping cavity 3, and damping cavity injects damping liquid.

[0020] The rotor 1 is annular, and the upper portion of the rotor 1 is provided with an outer rotating plate 9 and an inner rotating plate 8; the bottom center of the inner tooth seat 5 is provided with a cylinder 11, the cylinder 11 is inserted into the inner rotating plate 8, the cylinder is provided with a reinforcing rib 12, and the reinforcing rib 12 is located between the outer rotating plate 9 and the inner rotating plate 8.

[0021] The number of the inner rotating plate 8 is three, and the number of the reinforcing rib 12 is four, which are evenly distributed, and the outer rotating plate 9 is connected.
