[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] like Figures 1 to 4 As shown, the steering cylinder with a sealing and riveting structure of the cylinder head comprises a cylinder barrel 1 and a locking round nut 2, the cylinder barrel 1 comprises a cylindrical cylinder barrel body 10, the inner wall of the cylinder barrel body 10 is provided with a cylinder inner thread 12, one end of the cylinder barrel body 10 is provided with a cylinder barrel end face 11, the cylinder barrel end face 11 is provided with a plurality of recessed sealing and anchoring grooves 111, the locking round nut 2 comprises a cylindrical nut barrel body 21 and an annular nut end face 22, the outer wall of the nut barrel body 21 is provided with a nut outer thread 211, the nut end face 22 is provided with a plurality of riveting surfaces 221, and the position of the riveting surface 221 matches the sealing and anchoring groove 111.

[0019] It should be noted that the nut external thread 211 matches the cylinder internal thread 12 .

[0020] In addition, the nut end surface 22 is provided with a plurality of auxiliary spinning holes 222 .

[0021] In addition, the cross section of the sealing and anchoring groove 111 is rectangular.

[0022] The following is an explanation of how to use the steering cylinder with a cylinder cover sealing riveted structure.

[0023] like Figure 2 As shown, by utilizing the cooperation between the nut external thread 211 and the cylinder internal thread 12, the locking round nut 2 is screwed into the cylinder 1 until it fits to the bottom, and then the riveting surface 221 is impacted by pressing or tapping, so that the riveting surface 221 is embedded in the corresponding anchor groove 111 to form a sealing riveting structure.

[0024] Due to the limiting effect of the sealing riveting structure, the anti-loosening performance of the threaded connection is effectively enhanced to prevent the cylinder cover from loosening, thereby improving the reliability of the steering cylinder.

[0025] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
