Detailed Description

The technical solution of the present invention is further illustrated by the following examples. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The first embodiment is as follows:

an improved cylinder comprises a cylinder body 1, wherein the rear end part of the cylinder body 1 is provided with a rear end cover hole 11, and the inner wall of the rear end cover hole 11 is provided with an inner connecting thread 12;

the rear end cover 2 is arranged in the rear end cover hole 11, the side face of the rear end cover 2 is provided with an external connecting thread 21 matched with the internal connecting thread 12, and the lower part of the side face of the rear end cover 2 is provided with a sealing ring 22.

Specifically, cylinder body 1 and rear end cap 2 are connected with external connection screw thread 21 through interior connecting thread 12, during the installation, directly rotate rear end cap 2 into rear end lid hole 11, and sealing washer 22 is in sealed cooperation with the inner wall in rear end lid hole 11, compares in prior art jump ring joint, has got rid of the jump ring and has warp and cause the problem that the cylinder performance descends or even damages in the use, has improved the joint strength between end cap and the cylinder body, has prolonged the life of cylinder.

Example two:
