The invention provides a push-pull steel cable for an aircraft, relates to the field of spacecrafts, and solves the problem that a ball head bearing and a push-pull rod are easy to loosen after beingused for a period of time due to the fact that no locking structure is arranged between the ball head bearing and the push-pull rod and the problem that the whole device needs to be disassembled during lubrication and the maintenance difficulty is increased due to the fact that no lubricating structure is arranged between the ball head bearing and an operating rod after the ball head bearing is connected with the operating rod. A push-pull steel cable for an aircraft comprises a connecting base. A connecting pin structure is connected to the connecting base in an inserted mode, and a connecting sleeve is connected to the connecting base in a threaded mode. The sleeve structure is improved, during maintenance, due to the arrangement of the sleeve, on one hand, oil can be injected into a sleeve through an oil injection hole to guarantee lubrication of a steel wire rope, on the other hand, the contact quality of oil and the steel wire rope can be guaranteed through a sponge pipe, and dustcan be prevented from entering from the oil injection hole to make contact with the steel wire rope.
本发明提供一种航空器用推拉钢索,涉及航天器领域,解决了球头轴承和推拉杆之间无闭锁结构,在使用一段时间后球头轴承和推拉杆之间容易产生松动;球头轴承在连接操作杆后和操纵杆之间未设置润滑结构;在润滑时需要将本装置整体拆卸,增加了保养难度的问题。一种航空器用推拉钢索,包括连接座;所述连接座上插接有一个连接销结构,且所述连接座上螺纹连接有一个连接套。改进了套管结构,在维护时,因套管的设置,一方面,可通过注油孔向套管内注油保证钢丝绳的润滑,另一方面,通过海绵管可保证油料与钢丝绳的接触质量,且还可防止灰尘从注油孔处进入与钢丝绳接触。
