[0003] However, there are still certain defects in the existing piston device in use. Although the existing piston device can realize the transmission between forces, the existing piston rod is easy to be out of alignment with the push force due to the large pull-back force when the existing piston rod is in use. The plate breaks and falls out of the piston cylinder. If the piston rod and the push plate are integrated, it is not convenient to disassemble and repair, and the push plate collides with the top of the piston cylinder when the piston rod is pulled out, which will easily cause deformation and damage of the push plate. If the inside of the cylinder is not sealed, it will affect the use of the piston device

The invention discloses a piston device capable of buffering and anti-falling for a piston rod. The piston device capable of buffering and anti-falling for the piston rod comprises a piston rod, a piston cylinder, a rod hole, a piston cylinder bottom port, a piston cylinder top, a push plate, an inner pipe, an anti-explosion layer, the springs, gaskets, a bolt, a nut and a baffle. According to thepiston device, the springs are symmetrically installed on the push plate on the bottom of the piston rod, the spring gaskets are both arranged on the springs, so that the push plate of the bottom ofthe piston rod is not in direct contact with the piston cylinder top when the piston rod is pulled back to the highest point, the springs on the push plate of the piston rod are compress when the gaskets are in contact with the top of the piston cylinder, a buffer function is provided on the push plate, the push plate is prevented from impacting the cylinder top for a long time to damage the pushplate, and a large-area baffle is installed at the bottom of a connecting head of the push plate and the piston rod, the baffle with the bolt is fixed on the bottom of the piston rod, and the piston rod is prevented from falling off.
Description
technical field [0001] The invention relates to a piston device used for buffering and preventing falling off of a piston rod. Background technique [0002] The piston cylinder is a structural form of the hydraulic cylinder. The input is pressure and flow, and the output is thrust and speed. The piston movement is composed of a piston rod and a piston cylinder. The two are indispensable. The piston rod is responsible for pushing the piston inside the cylinder. Air is used to generate pressure and thus transmitted. [0003] However, there are still certain defects in the existing piston device in use. Although the existing piston device can realize the transmission between forces, the existing piston rod is easy to be out of alignment with the push force due to the large pull-back force when the existing piston rod is in use. The plate breaks and falls out of the piston cylinder. If the piston rod and the push plate are integrated, it is not convenient to disassemble and rep...
