The invention relates to a locking device for the tail end of a satellite-borne periscopic two-dimensional rotary table, and belongs to the technical field of locking devices. The technical problems that in the prior art, a locking device is not high in force bearing performance or can only provide local locking or can not be repeatedly used, and application of the locking device in the aerospace field is limited are solved. The satellite-borne periscopic two-dimensional turntable tail end locking device comprises a two-dimensional turntable, an optical load, a base, a locking movable part and a plurality of matched locking parts. According to the device, the memory alloy switch is used for driving, the lever assembly is used for amplifying locking force, the spring assembly is used for achieving bounce-off after unlocking, the mixed locking mode of multi-point pressing and single-point locking is adopted, mechanical transmission supporting is conducted through multiple pressing points, the stability and the dynamic characteristic are improved, meanwhile, only one locking point exists, the reliability is improved, and the locking effect is good. And the device is small in size and light in weight, and can be repeatedly locked and unlocked.

    本发明涉及一种星载潜望式二维转台末端锁紧装置,属于锁紧装置技术领域。解决了现有技术中的锁紧装置或是承受力的性能不强,或是只能提供局部锁紧,或是不能重复使用,在航天领域中的应用都有局限性的技术问题。本发明的星载潜望式二维转台末端锁紧装置,包括二维转台、光学负载、基座、锁止可动部分和若干配合锁止部分。该装置利用记忆合金开关作为驱动,利用杠杆组件放大锁紧力,用弹簧组件实现解锁后弹开,并采用多点压紧结合单点锁紧的混合锁紧方式,利用多个压紧点进行力学传递支撑,提高稳定性和动力学特性,同时只有一个锁紧点,提高可靠性,且装置体积小、质量轻,可重复锁紧、解锁。
