Abstract

The invention relates to a quick-locked light pose adjustable connecting mechanism. The mechanism comprises at least one connecting chain; each connecting chain comprises at least one motion pair andat least one connecting rod; each motion pair is connected with each connecting rod; end surface joints are formed in two ends of each connecting chain; thermotropic bonding materials are arranged inthe motion pairs; and heating devices for quickly heating the thermotropic bonding materials are arranged in the motion pairs or on the outer surfaces of the motion pairs. The mechanism can realize different connecting angles through the pose-adjustable connecting chains, and can realize different connecting lengths through any combination of multiple connecting chains to reduce the types of connecting modules.

Description

technical field [0001] The invention relates to the technical field of mechanical connections, in particular to a fast-locking, lightweight, posture-adjustable connection mechanism. Background technique [0002] For the task of splicing a large number of similar modular units into a large structure in ground or space tasks, there are multiple connection requirements of different lengths, angles, and sizes. Currently, pre-customized connection components of various sizes, on-site cutting— Measures such as welding connecting components of different sizes and pre-developing universal connecting components with adjustable posture and locking, but the existing connecting components have the following technical defects: [0003] (1) The use of pre-customized connection components of various sizes can simplify the system structure of a single connection component and reduce the weight of the connection component, but it will lead to problems such as many types of connection compone...
