Cylinder

摘要

A cylinder includes a cylinder body assembly, a cylinder rod assembly, and a piston assembly. The cylinder body assembly includes a cylinder body. The cylinder body defines a receiving chamber. The cylinder rod assembly includes a rod fixed with the cylinder body. The rod includes an inclined resisting surface. The piston assembly includes a piston, a piston rod, and one or more resisting member. The piston is slidably received in the receiving chamber and sleeved on the rod. The piston rod protrudes from the piston and extending out from the receiving chamber. The piston rod is sleeved on the rod, and defines a through hole. The resisting member is movably mounted in the through hole. The piston and the piston rod slide relative to the rod, which enable the resisting surface to resist the resisting member to be partially exposed from the through hole.

1. A cylinder, comprising:
a cylinder body assembly comprising a cylinder body defining a receiving chamber; a cylinder rod assembly comprising a mounting base, a rod, and a connecting rod, the mounting base being received in the receiving chamber and defining a through hole, the rod being inserted in the mounting base through the through hole and being fixed with the mounting base by the connecting rod; the rod comprising an inclined resisting surface; and a piston assembly comprising:
a piston slidably received in the receiving chamber and sleeved on the rod;a piston rod protruding from the piston and extending out from the receiving chamber, the piston rod sleeved on the rod, and defining at least one through hole; andat least one resisting member movably mounted in the at least one through hole, wherein the rod comprises a rod body and a pushing end at a distal end of the rod body away from the piston, the pushing end comprises a first section and a second section, the first section interconnects the rod body with the second section, the first section is a frustum of a cone, the inclined resisting surface is at an outer sidewall of the first section, the second section is substantially cylindrical, and protrudes outwardly from a distal end of the first section; the piston and the piston rod slide relative to the rod, which enable the inclined resisting surface of the rod to resist the at least one resisting member to be partially exposed from the at least one through hole of the piston rod; and wherein the piston rod is substantially hollow cylindrical, and the piston assembly further comprises a dust cover, and the dust cover is detachably mounted on the piston rod to cover an end of the piston rod away from the piston.
