The invention relates to a seat rotation locking mechanism and a using method thereof, and belongs to the technical field of passenger train equipment. According to the technical scheme, armrest supporting arms are arranged on the left side and the right side of a rotating frame framework, a seat framework is fixedly arranged on the upper end face of the rotating frame framework, locking adjusting mechanisms of the same structure are arranged between the left side and the right side of the seat framework and the rotating frame framework, each locking adjusting mechanism comprises a positioning pin mechanism, an adjusting mechanism and an adjusting brake cable, and openings are formed in the armrest supporting arms; one end of the adjusting mechanism penetrates through the opening, the outer edge of the end is flush with the outer edge of the opening of the armrest supporting arm, the end is a key connector matched with a key, and the other end of the adjusting mechanism controls the positioning pin mechanism to act through an adjusting brake cable. The invention has the positive effects that the structure is simple and reliable, the cost is low, the rotation of the seat can be realized only through key operation, and the potential safety hazard that the one-step return seat is not rotated in place and is operated improperly is effectively avoided.
本发明涉及一种座椅旋转锁止机构及其使用方法,属于铁路客车设备技术领域。技术方案是:转架骨架的左右两侧均设有扶手支臂,转架骨架上端面固定设有座骨架,座骨架的左右两侧与转架骨架之间均设有结构相同的锁止调节机构,所述锁止调节机构包含定位销机构、调节机构和调节闸线,扶手支臂上设有开口,调节机构的一端穿过开口,该端外边缘与扶手支臂上开口处的外边缘持平,此端为钥匙相匹配的钥匙接口,调节机构的另一端通过调节闸线控制定位销机构动作。本发明的积极效果:结构简单可靠,成本低廉,通过钥匙操作才能实现座椅旋转,有效避免了一踏式回位座椅旋转不到位及不正当操作的安全隐患。
