Title:
CONNECTING STRUCTURE FOR PISTON AND PISTON ROD OF PUSH ROD CYLINDER
Document Type and Number:
WIPO Patent Application WO/2022/077610
Kind Code:
A1
Abstract:
A connecting structure for a piston (1) and a piston rod (2) of a push rod cylinder, comprising: a piston (1), and a piston rod (2) and connecting components (3) which mate with the piston (1). The connecting components (3) are disposed on a connecting end surface (4) of the piston rod (2). The connecting end surface (4) is equidistantly provided with a plurality of locking notches (5). Each connecting component (3) comprises a screwing structure (31) having a viscous structure (32). The screwing structure (31) is arranged in a corresponding locking notch (5). The viscous structure (32) is arranged between the locking notch (5) and the screwing structure (31). On the basis that the piston (1) is threadedly connected to the piston rod (2), the thread of the part where the piston (1) is connected to the piston rod (2) is compressed tightly by the screwing structure (31) having the viscous structure (32) on each locking notch (5) to ensure the firmness of the connection between the piston rod (2) and the piston (1).
