[0002] A hydraulic cylinder is a component that converts hydraulic energy into mechanical energy and performs linear reciprocating or swinging motion. Since the hydraulic cylinder has a simple structure and reliable operation, it can eliminate the need for a deceleration device when used to achieve reciprocating motion, and there is no transmission gap, and it can also ensure smooth movement. Therefore, hydraulic cylinders are widely used in the mechanical field. Usually, a hydraulic cylinder consists of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application scenario, and other devices are indispensable.

[0003] During the use of hydraulic cylinders, the piston rod is the key transmission component for realizing reciprocating motion. It is responsible for converting hydraulic pressure into mechanical motion. The stability and accuracy of its connection with other devices directly affect the performance and reliability of the entire hydraulic system. The connecting lug, as a bridge between the piston rod and other equipment or components, the connection between the piston rod and the connecting lug is one of the key links.

[0011] As an optimization, a fixing block is installed on the vertical plate, the fixing block extends into the fixed adjustment hole, and the outer wall of the fixing block fits the inner wall of the fixed adjustment hole. The setting of this optimization scheme can play an auxiliary fixing role for the articulated sleeve, making the articulated sleeve more firmly fixed on the connecting seat.

[0012] As an optimization, an arc pad is installed on the additional bolt, and the arc pad fits the outer wall of the enclosure. In the configuration of this optimization scheme, the inner end surface of the arc pad fits the outer end surface of the enclosure, so that the additional bolt reduces damage to the enclosure when tightened, and the additional bolt is tightened more.

[0013] As an optimization, two articulated sleeves are provided, the two articulated sleeves are arranged in mirror image, and the connecting seat is located between the two articulated sleeves. The arrangement of this optimization scheme facilitates the installation of the articulated sleeves.

[0014] The beneficial effects of the utility model are as follows: the utility model can adjust the connecting seat according to the position of the device and the piston rod, can eliminate installation errors and make the device and the piston rod smoothly docked together, and at the same time can select different installation methods according to the different connection methods between the device and the piston rod.
