The invention provides a self-locking joint for space truss structure connection. An elastic block joint is inserted into a square cabin, a trapezoidal convex block of the elastic block joint is matched with a trapezoidal through hole in the lower bottom face of the square cabin, arc-shaped elastic blocks of the elastic block joint are compressed firstly, then bounce off and finally are locked insquare holes in the left side face and the right side face of the square cabin, thus self-locking is completed, when unlocking is needed, two cross-shaped buttons of a spring button are pushed and pressed till actuating blocks of the cross-shaped buttons extrude the arc-shaped elastic blocks to enable the arc-shaped elastic blocks to be retracted into the elastic block joint, then unlocking can becompleted, and a truss rod piece connected with the elastic block joint is taken away. The direction of a rotatable joint can be changed, and the mounting direction of the rod piece can be further flexibly adjusted; the operation precision needed by a robot and the operation difficulty can be reduced, automatic locking of two parts can be completed, through a spring button structure, the unlocking process can be completed, the functions of automatic locking and disassembly separation in the mounting process are realized, and operation of the robot is facilitated.
本发明提供了一种用于空间桁架结构连接的自锁接头,弹块接头插入方舱之中,弹块接头的梯形凸块与方舱下底面的梯形通孔相匹配,弹块接头的弧形弹块先压缩再弹开,最终锁定在方舱左右两侧面的方形孔中,从而完成自锁,当需要解锁时,推动按压弹簧按钮的两个十字按钮,直至十字按钮的作动块挤压弧形弹块收回至弹块接头内,便可完成解锁,取走与弹块接头相连的桁架杆件。本发明可以改变可旋转接头的方向,进一步可以灵活调整杆件的安装方向;可减小了机器人需要的操作精度和操作难度,能够完成两部分的自动锁定,通过弹簧按钮结构可以完成解锁过程,完成了安装过程中的自动锁定和拆卸分离功能,方便机器人进行操作。
