Pantograph type current collector damper

The invention discloses a pantograph type current collector damper. The pantograph type current collector damper comprises a piston rod (1), a left end cover (2), a cylinder barrel (3), a piston (4),a spacer (5), a locking nut (6), an outer sleeve (7), a right end cover (8), a pin head (9), a spring (10), a sleeve (11), an annular valve core (12) and a guide sleeve (13). The pantograph type current collector damper is widely applied to electric locomotives such as bullet trains and G-series high-speed trains, impact on a pantograph type current collector in the descending process of the pantograph type current collector can be effectively reduced, reliable work of the pantograph type current collector is guaranteed in the vehicle operation process, and serious accidents are avoided. The pantograph type current collector damper is simple and novel in structure, and reliable guarantee is provided for domestication of the pantograph type current collector damper. 本发明公开了种受电弓阻尼器，所述受电弓阻尼器包括活塞杆（1）、左端盖（2）、缸筒（3）、活塞（4）
