The invention belongs to the field of airplane connecting and bearing structure design, and particularly relates to a length-adjustable quick-release pull rod. Comprising a pull rod A connector assembly 11, a pull rod B connector assembly 12 and a rod body 13. A stop pin mounting hole and an unlocking rod mounting hole are formed in the first internal thread section, an unlocking ring is mounted in the first internal thread section through an unlocking rod and a nut, the first internal thread section is in threaded connection with the first external thread section, the ratchet wheel is clamped through a stop pin, and the pull rod A connector assembly is prevented from rotating reversely; a stop pin mounting hole and an unlocking rod mounting hole are formed in the second internal thread section, an unlocking ring is mounted in the second internal thread section through an unlocking rod and a nut, the second internal thread section is in threaded connection with the second external thread section, the ratchet wheel is clamped through a stop pin, and reverse rotation of the pull rod B connector assembly is prevented; by means of the ratchet mechanism, fine adjustment of the length and the pre-tightening force of the pull rod is achieved, automatic locking is completed, and rapid unlocking of the ratchet wheel can be achieved by designing the unlocking mechanism.

    本申请属于飞机连接与承载结构设计领域,特别涉及一种可调长度快卸拉杆。包括:拉杆A接头组件11、拉杆B接头组件12以及杆体13。第一内螺纹段上开设有止动销安装孔和解锁杆安装孔,第一内螺纹段内部通过解锁杆和螺母安装有解锁环,第一内螺纹段与第一外螺纹段螺纹连接,并通过止动销卡住棘轮,防止拉杆A接头组件逆向转动;第二内螺纹段上开设有止动销安装孔和解锁杆安装孔,第二内螺纹段内部通过解锁杆和螺母安装有解锁环,第二内螺纹段与第二外螺纹段螺纹连接,并通过止动销卡住棘轮,防止拉杆B接头组件逆向转动;本申请使用棘轮机构不仅实现了拉杆长度和预紧力的精细调整,并完成了自动锁死,设计解锁机构可实现棘轮的快速解锁。
