The invention discloses a propeller blade self-locking device which comprises a rubber sleeve, a first limiting assembly and a second limiting assembly, the first limiting assembly and the second limiting assembly each comprise a first rack, a second rack, a ratchet wheel, a gear, a pawl, a fixing rod, a spring and a base, and the gear and the ratchet wheel are coaxially arranged; the gear is located between the first rack and the second rack and meshed with the first rack and the second rack, the fixing rod is fixed to the base and located between the first rack and the second rack, the pawl is rotatably connected to the upper end of the fixing rod and meshed with the first rack, and one end of the spring is fixedly connected with the pawl. The other end of the spring is fixedly connected with the fixing rod, and a telescopic assembly is connected between the two bases. By the adoption of the self-locking device, the propeller blades can be prevented from rotating in the non-working state, the self-locking function of the propeller blades is achieved, and the self-locking device is low in manufacturing cost, stable in structure and easy to operate.

    本发明公开了一种螺旋桨桨叶自锁装置,其包括橡胶套、第一限位组件和第二限位组件,第一限位组件和第二限位组件均包括第一齿条、第二齿条、棘轮、齿轮、棘爪、固定杆、弹簧和底座,齿轮与棘轮呈同轴设置,齿轮位于第一齿条和第二齿条之间且分别与第一齿条和第二齿条啮合,固定杆固定在底座上且位于第一齿条和第二齿条之间,棘爪可转动地连接在固定杆的上端且与第一齿条啮合,弹簧的一端与棘爪固定连接,弹簧的另一端与固定杆固定连接,两个底座之间连接有伸缩组件;采用本发明,能够避免螺旋桨桨叶在非工作状态下发生转动,实现旋桨桨叶的自锁功能,造价低廉,结构稳固且易于操作。
