description The utility model relates to a loose joint type double-plunger pump. The double-plunger pump mainly solves the problems that due to hard connection between double plungers of an existing double-plunger pump, the size of a component is too long, machining is not easy, and eccentric wear of the plungers is easily caused. Comprising an upper plunger (4) and a lower plunger (9), the upper end of the lower plunger (9) is connected with a lower plunger upper end (12), and the upper plunger (4) and the lower plunger upper end (12) are connected through a movable connector (7). According to the loose joint type double-plunger pump, the double plungers are connected through the movable joint, so that the machining difficulty and the machining cost are reduced, the assembly precision is improved, and the service life of the plunger pump is prolonged. 本实用新型涉及一种活接式双柱塞泵。主要解决现有的双柱塞泵由于双柱塞之间因硬连接造成的部件尺寸过长不易加工、易导致柱塞偏磨的问题。包括上柱塞（4）、下柱塞（9），下柱塞（9）上端连接有下柱塞上端头（12），所述上柱塞（4）和下柱塞上端头（12）之间通过活动接头（7）相连。该活接式双柱塞泵将双柱塞通过活动接头进行连接，从而降低了加工难度及加工成
