Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] A self-locking joint used for the connection of space truss structures comprises a petal joint, a rotatable joint, two spring buttons and a bullet joint.

[0031] The petal joint includes an adapter piece 1 and an adapter piece. A through hole is provided in the center of the adapter piece 1 (1), and a through hole is provided in the middle of the adapter piece. Two bosses are arranged on the outer wall of the adapter piece, and the two bosses There is a 90-degree angle between the platforms, and a groove (3) is opened on each boss away from the through hole, and through holes are opened on the side walls on both sides of the groove, and the two through holes are coaxial, and the two bosses The plane formed by the axis of the through hole is perpendicular to the axis of the through hole in the middle of the adapter. A truss member is inserted int...

Abstract

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.

Description

technical field [0001] The invention relates to the field of mechanical design and processing, in particular to a self-locking joint device. Background technique [0002] Due to the limitations of the volume and carrying capacity of the launch vehicle, large structures in space, such as solar power plants, large communication antennas, and space stations, cannot be sent into space in one launch. This requires multiple launches and then assembly on the space station, and the support structure of these large spacecraft is mainly a truss structure. The research status and development trends related to construction technology show that there are certain limitations in human on-orbit assembly. On-orbit assembly by someone is only capable of small tasks, short time, and relatively simple assembly tasks. For future space assembly tasks with complex structures, huge volumes, harsh installation environments, and high precision requirements, manned assembly cannot meet the task requ...
