Description

Technical Field

[0001] The utility model belongs to the field of connecting structures of cylinder shafts and connecting sleeves, and in particular relates to a connecting structure of cylinder shafts and connecting sleeves with stable connection. Background Art

[0002] A cylinder is a device used to convert pressure energy into mechanical energy. It consists of a hollow cylinder and a movable piston. When gas or liquid is injected into the cylinder, the piston will move in one direction under the action of pressure. This movement can be used to drive other mechanical devices, such as engines or hydraulic systems. The design and manufacture of cylinders need to take into account factors such as working conditions, working media, pressure and temperature. High-quality cylinders should have good sealing, wear resistance and corrosion resistance to ensure stable and reliable mechanical movement. The connection structure between the cylinder shaft and the connecting sleeve refers to a structure that can connect the cylinder shaft and the connecting sleeve. In the prior art, the device does not have a lubrication mechanism, and when the screw is used, the screw is not easy to be lubricated, resulting in the screw on the device not being smooth to use, and when the screw on the device is used for a long time, the device has no limiting mechanism, and the screw may become loose after long-term use, resulting in unstable connection of the device.
