Description

Technical Field

[0001] The utility model relates to the technical field of rocker arm anti-falling tooling, in particular to a rocker arm anti-falling tooling. Background Art

[0002] We usually say that the rocker arm in the internal combustion engine of automobiles, ships, motorcycles, and reciprocating aircraft engines is a rocker lever that transmits radial motion through the cam's lobes, makes linear motion on the lift valve, and then extends the rocker arm.

[0003] After searching, the Chinese patent with publication number CN219545867U discloses a rocker arm anti-falling tooling, which solves the problem that the rocker arm used in the traditional rocker arm vibrating conveyor is usually provided with three connecting holes. During installation, rubber strips for shock absorption and buffering are installed around each connecting hole. Since the rubber strips are installed by extrusion, the rubber strips are easily worn during operation. However, this device cannot prevent the rocker arm from falling off. In the process of using the fixing cap to prevent the rocker arm from falling off, the fixing cap needs to be quickly installed to reduce the time of installing and fixing the rocker arm.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
