A safety latch system (200) includes a mount (208), a pawl member (214), a ratchet member (202), and a release assembly. The mount may be mounted on a housing (142) of the piston. The pawl member is coupled to the mount. The pawl member includes a pawl. The ratchet member has a first side wall including a first connection portion connectable to an end portion of a piston rod (144) of the piston. The first side wall includes a tooth portion configured to engage with the pawl. The release assembly is configured to provide an engaged state between the pawl member and the ratchet member. The release assembly is also configured to provide a disengaged state between the pawl member and the ratchet member. In the joint state, the pawl component is jointed with the ratchet wheel component; security latch system such that the security latch system is configured to provide (i) an unlocked condition in which the ratchet member is movable relative to the pawl member when the piston rod is advanced outwardly from the housing and (ii) an unlocked condition in which the ratchet member is movable relative to the pawl member when the piston rod is advanced outwardly from the housing wherein the pawl member is configured to be locked into a recess between adjacent teeth of the ratchet member to prevent the piston rod from moving toward the housing in a locked state. When in the disengaged state, the pawl member is disengaged from the ratchet member to permit the piston rod to advance outwardly from the housing and to permit the piston rod to retract toward the housing.

    一种安全闩锁系统(200)包括安装件(208)、棘爪构件(214)、棘轮构件(202)和释放组件。所述安装件可安装在活塞的壳体(142)上。所述棘爪构件耦接到所述安装件。所述棘爪构件包括棘爪。所述棘轮构件具有第一侧壁,所述第一侧壁包括可连接到所述活塞的活塞杆(144)的端部部分的第一连接部分。所述第一侧壁包括齿部,所述齿部被配置成与所述棘爪接合。所述释放组件被配置成提供所述棘爪构件与所述棘轮构件之间的接合状态。所述释放组件还被配置成提供所述棘爪构件与所述棘轮构件之间的脱离状态。当在所述接合状态中时,所述棘爪构件与所述棘轮构件接合,使得所述安全闩锁系统被配置成提供(i)其中当所述活塞杆从所述壳体向外推进时所述棘轮构件可相对于所述棘爪构件移动的解锁状态以及(ii)其中所述棘爪构件被配置成锁定到所述棘轮构件的相邻齿之间的凹部中以阻止所述活塞杆朝向所述壳体移动的锁定状态。当在所述脱离状态中时,所述棘爪构件与所述棘轮构件脱离以准许所述活塞杆从所述壳体向外推进并准许所述活塞杆朝向所述壳体缩回。
