The invention provides a mechanical control box with a double-spring acting mechanism. The mechanical control box comprises a box body (1), an upper-section steel cable (3), a locking support arm (4), a pawl (6), an upper tension spring (8), a switching rocker arm (9), a lower-section steel cable (10) and a lower tension spring (11), and the upper tension spring (8) and the lower tension spring (11) which are arranged in parallel up and down are connected with the pawl (6) through the switching rocker arm (9), so that the problems that the spring force is obviously attenuated in the pulling process and the tension cannot meet the requirement when the mechanical control box of a single spring acting mechanism is applied to a novel hanging system are solved under the condition that the volume is basically unchanged.

    本发明提供了一种带有双弹簧作用机构的机械控制盒,包括:盒体(1)、上段钢索(3)、锁闭支臂(4)、棘爪(6)、上拉力弹簧(8)、转接摇臂(9)、下段钢索(10)和下拉力弹簧(11);上下平行设置的上拉力弹簧(8)和下拉力弹簧(11)通过转接摇臂(9)连接棘爪(6),在保证了体积基本不变的情况下,解决了单弹簧作用机构的机械控制盒应用在新型吊挂系统中其弹簧力在拉动过程中衰减明显,拉力不能满足要求的问题。
