[0024] This embodiment is a rocker arm structure that prevents breakage.
[0025] As Figures 1-4 shown, it includes a rocker arm 1. A brake cable mounting hole 2 is opened at one end of the rocker arm 1. A groove 3 is opened at the other end of the rocker arm 1. A camshaft mounting hole 4 is provided at the lower end of the groove 3. A reinforcing rib plate 6 is arranged in the middle of the outer surface of the upper end of the rocker arm 1. An anti-detachment component 5 is installed at one end of the outer surface of the upper end of the rocker arm 1 close to the camshaft mounting hole 4. The anti-detachment component 5 includes a limit arm plate 8, a fixed block 9, a rotating shaft 10, a threaded hole 11, a screw rod 12, a gasket 13, an installation cavity 14, a fixed limit block 15, a movable limit block 16 and a torsion spring 17. And a fixing screw 7 is arranged between the reinforcing rib plate 6 and the rocker arm 1. The reinforcing rib plate 6 is fixedly installed on the outer surface of the upper end of the rocker arm 1 through the fixing screw 7.
[0026] The fixed block 9 is fixedly installed at one end of the outer surface of the upper end of the rocker arm 1 close to the groove 3. The installation cavity 14 is opened inside the fixed block 9. The fixed limit block 15, the movable limit block 16 and the torsion spring 17 are all located in the installation cavity 14. The fixed limit block 15 is fixedly installed on one side of the bottom of the installation cavity 14. The lower end of the rotating shaft 10 extends into the installation cavity 14. The movable limit block 16 is fixedly installed on the upper part of the outer surface of one side of the rotating shaft 10. The torsion spring 17 is movably sleeved on the outer wall of the lower part of the rotating shaft 10, and the torsion spring 17 is fixedly installed between the fixed limit block 15 and the movable limit block 16. A sealing bearing is arranged between the rotating shaft 10 and the fixed block 9. The rotating shaft 10 is rotatably connected with the fixed block 9 through the sealing bearing. The outer wall of the upper part of the rotating shaft 10 is fixedly connected with one end of the limit arm plate 8 far from the groove 3. One end of the limit arm plate 8 extends into the upper part of the groove 3. The threaded hole 11 is opened at one end of the outer surface of the upper end of the limit arm plate 8 far from the rotating shaft 10.
