Description

一种无人机折叠结构 技术领域
本发明涉及无人机技术领域，更具体地说，涉及一种无人机折叠结构。
 背景技术
无人机可搭载多种负载完成各种复杂任务，在航拍、农植保护等领域起着十分重要的作用；目前使用的用于植保作业的农业多旋翼无人机大都无法将机臂进行折叠，在田间作业转场和外出作业运输时均十分不便。
 技术问题
本发明要解决的技术问题在于，针对现有技术的上述缺陷，提供一种机臂可折叠的无人机折叠结构。
 技术解决方案
本发明解决其技术问题所采用的技术方案是：
构造一种无人机折叠结构，包括机臂和机臂安装座；其中，还包括机臂旋转块，所述机臂旋转块与所述机臂端部下表面固定连接；所述机臂旋转块与所述机臂安装座通过螺杆可转动连接；所述螺杆搭配有用于调节松紧的防松螺母；所述机臂与所述机臂旋转块连接一端端部上表面固定连接有机臂锁块；所述机臂安装座上可拆卸连接设置有机臂锁扣，所述机臂锁扣一端设置有挡块。
本发明所述的无人机折叠结构，其中，所述机臂安装座上还设置有用于对所述机臂旋转块转动限位的限位块。
本发明所述的无人机折叠结构，其中，所述机臂上还固定设置有电调。
本发明所述的无人机折叠结构，其中，所述电调上设置有散热板。
本发明所述的无人机折叠结构，其中，所述机臂为方形机臂。
 有益效果
本发明的有益效果在于：在需要使用时，只需调松防松螺母，将机臂向上抬起，而后调紧防松螺母，同时调节机臂锁扣使挡块挡住机臂锁块，十分方便快捷，便于转运，且机臂紧固效果好；整体结构简单，成本低。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将结合附图及实施例对本发明作进一步说明，下面描述中的附图仅仅是本发明的部分实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他附图：
