As shown in Figure 1, the utility model is realized, which comprises a hinge cup 1, an outer rocker arm 2, an inner rocker arm ₃ , a hinge arm 4, a base 5, a dialing piece 6, a U-shaped pin 7, a rivet 8, a spring 9, a locking screw 10 and an adjusting screw 11, the structure is: the inner rocker arm 3 comprises a rocker arm assembly 12 and a damper formed by a steel ball clutch mechanism connected to the rocker arm assembly 12; the inner rocker arm 3 The outer rocker arm 2 and the hinge cup 1 and the hinge arm 4, which are respectively connected to both sides thereof, together form a four-bar linkage mechanism.

As shown in FIGS. 2 and 4, the damper includes a jacket 13, an inner sleeve 14, an eccentric shaft 15, a rolling assembly 16, a rubber ring 17, a first sealing ring 18, a second sealing ring 19, and a jacket and a body. The damping rubber 20 between the sleeves; the eccentric shaft 15 is located in the waist groove of the inner sleeve 14; as shown in FIG. 3, the inner sleeve 14 located on the outer circumference of the waist groove is evenly arranged with a plurality of rolling components for placing a profiled hole of 16, a first seal ring 18 and a second seal ring 19 are respectively connected to the two ends of the inner sleeve 14, and the inner sleeve 14 and the outer sleeve 14 abut against the end of the second seal ring 19 are further provided for positioning. Apron 17.

Preferably, the rolling assembly 16 is a steel ball or a steel needle, and the number of the steel balls or steel needles is greater than or equal to 3. The end of the eccentric shaft 15 is provided with a cylindrical projection 1502, and the axis of the cylindrical projection 1502 is offset from the axis of the eccentric shaft 15. As shown in FIG. 5, the stud bump 1502 is connected to the toggle The waist of the piece 6 is inside the hole. The shaped hole is in communication with the waist groove. The shape of the shaped hole is matched to the size of the cross-sectional shape of the rolling assembly 16 located therein.

The assembly process and working principle of the utility model are as follows.

First, the assembly process of the damper is such that the first sealing ring 18 is sleeved into one end 1402 of the inner sleeve 14, and the inner sleeve 14 of the first sealing ring 18 is sleeved into the outer casing 13, and the damping rubber 20 is filled. Between the inner sleeve 14 and the outer sleeve 13; after filling the damping rubber 20, the second sealing ring 19 is placed on the other end 1403 of the inner sleeve 14, and then inserted into the rubber ring 17; the first sealing ring 18, the second sealing ring 19 The sealing function is applied, and the damping rubber 20 is prevented from flowing out, and the rubber ring 17 is positioned; the rolling assembly 16 (three steel needles or three steel balls) is placed in the shaped hole 1404 of the inner sleeve 14. Then, the components of the rolling assembly 16 are first snapped into the rocker arm assembly 12; then the end of the 15 eccentric shaft away from the cylindrical projections is inserted into the holes 1204 of the rocker arm assembly 12 and the waist grooves of the inner sleeve 14.
