Embodiment 1

[0045] Step 1, fix the load mounting structure 300 of the load mounting interface 100 with the exposed load; insert the spherical structure 400 of the load mounting interface 100 into the load locking pointing assembly 200, and use both the load mounting interface 100 and the load locking pointing assembly 200 The fixing method of the preload is fixed;

[0046] Step 2, fixedly connect the external handle connection device and the exposed load connection device;

[0047] Step 3, moving and fixing the external handle connection device of the exposed load connection device, so that the handle is inserted into the external handle connection device, and the two are fixed by means of pre-tightening force.

Embodiment 2

[0049] Step 1, move the connecting device of the external handle so that the handle is inserted into the connecting device of the external handle, and the connecting device of the external handle and the handle are fixed by means of pre-tightening force;

[0050] Step 2, fixedly connect the external handle connection device and the exposed load connection device.

[0051] Step 3, fix the load mounting structure 300 of the load mounting interface 100 with the exposed load; insert the spherical structure 400 of the load mounting interface 100 into the load locking pointing assembly 200, and use both the load mounting interface 100 and the load locking pointing assembly 200 The fixing method of the preload is fixed;

[0052] Among them: the load locking pointing assembly 200 includes: handle A1, guide driving pin A2, anti-loosening device 3, snap ring 4, housing A5, spring A6, sphere safety baffle 7, sphere safety baffle limit block 8, passive Friction cup 9, limit block driving...

Abstract

The invention discloses a connecting device applied between an outboard handle of a spacecraft and an exposed load. The connecting device comprises an outboard-handle connecting device and an exposed-load connecting device; the outboard handle of the spacecraft and the exposed load are peripheral equipment; the outboard-handle connecting device and the exposed-load connecting device are connected; the exposed-load connecting device comprises a load mounting port and a load fastening and positioning assembly; the load mounting port consists of a spherical structure and a load mounting structure, and is in integral design; the load mounting structure is fixed with the exposed load; the load fastening and positioning assembly fixes the spherical structure by utilization of a fixing manner of pretightening force; and the outboard-handle connecting device fixes the handle by utilization of the fixing manner of pretightening force. Through the adoption of the connecting device disclosed by the invention, guiding mounting, reliable fixation, precise positioning and overload protection of the exposed load and the outboard handle are realized, so that the connecting device provides a technical support for rapidly mounting the exposed load and the outboard handle at set outboard positions.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a connecting device suitable for an outer handle of a spacecraft and an exposed load. Background technique [0002] Space vehicles such as space stations and manned spacecraft have arranged a large number of handles for astronauts on the outer wall of the cabin to facilitate the movement and fixation of astronauts when they leave the cabin. If some handles are used to fix small exposed loads outside the cabin, the space vehicle will be greatly expanded. exposure test capabilities. At present, the International Space Station has used the external handle to fix the material exposure experiment box to conduct long-term material exposure experiments. [0003] However, for the exposed load outside the cabin and the handle outside the cabin, the connecting device in the prior art cannot automatically capture the exposed load outside the cabin and the handle outside the cabin, and has...
