The invention provides a manual and pneumatic integrated jack with improved oil ways. The manual and pneumatic integrated jack comprises a jack body, a manual driving mechanism and a pneumatic driving mechanism, wherein a first oil way integrated module and a second oil way integrated module are respectively connected between the jack body and the pneumatic driving mechanism and between the jack body and the manual driving mechanism respectively through oil ways; conversion of hydraulic oil in an inner cylinder and an outer cylinder of the jack body is completed; the first oil way integrated module and the second oil way integrated module are consistent in structure; and the first oil way integrated module comprises an integrated seat and an integrated block which are connected with each other through a quick disassembly structure. A manual driving mode and a pneumatic driving mode are set, and switching between the manual driving mode and the pneumatic driving mode is facilitated; the integrated seat and the integrated block are mutually connected through the quick disassembly structure and are convenient to disassemble and wash; a better oil sealing effect is achieved; and secondly, the defects that if a spring is adopted to be matched with a steel ball, the spring is prone to being expanded by the steel ball along with the increase of service time, the steel ball is finally clamped, and faults occur can be effectively prevented.

    本发明提出了一种油路改良型的手气动一体式千斤顶,包括千斤顶本体,及手动驱动机构;及气动驱动机构;千斤顶本体与气动驱动机构及手动驱动机构之间分别通过油路连接第一油路集成模块及第二油路集成模块;完成千斤顶本体内缸与外缸内液油的转换;第一油路集成模块与第二油路集成模块结构一致;第一油路集成模块包括集成座和集成块,集成座和集成块通过快拆结构相互连接;本申请将设置手动及气动两种驱动方式,方便两者之间的转换;集成座和集成块通过快拆结构相互连接,方便拆洗;达到更好的封油效果;其次可以有效防止若采用弹簧配合钢珠,随着使用时间的增长,弹簧容易被钢珠胀大,最终卡住钢珠,出现故障的缺陷。
