Description

Technical Field

[0001] The utility model relates to the technical field of cylinders, in particular to a low-friction cylinder facilitating trachea connection. Background Technique

[0002] A low-friction cylinder refers to a cylinder with extremely small friction between the piston and the cylinder barrel during the piston movement or startup. As a precise driving element and testing element, this kind of cylinder has a wide range of uses. A dual-channel control low-friction cylinder has two chambers in one cylinder, and two pistons operate in the two chambers.

[0003] There are still certain drawbacks in the dual-channel control low-friction cylinders in the prior art. For example, when the cylinder is connected to the trachea for work, the trachea is usually embedded and installed on the cylinder. When installing different specifications of pipe diameters, it is easy to cause installation mismatch, which limits the adaptability of the cylinder. Moreover, after the trachea is installed, there is no support, and it is also easy to bend at the connection end with the cylinder, which is easy to damage the connecting pipe and is not conducive to the operation of the cylinder.
