Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] The overall structure of the present invention is shown in Fig. 1(a) and Fig. 1(b). In the locked state, the locked structure is supported on the rotating support base 1 through the adapter plate 2, and the rotating support base 1 is supported on the casing 4; the spring cover 6 is fixed on the top of the locking bolt 7, and the pre-compressed release spring 5 is installed between the spring gland 6 and the adapter plate 2, and the preload is applied to the locking bolt 7 through the loading nut 8 during connection, thereby compressing the spherical gasket 9, the adapter plate 2 and the rotating support seat 1, and locking The lower end of the tightening bolt 7 cooperates with the combined split nut 16; under the effect of the pretightening force of the locking bolt 7, the spatial positions of the adapter plate 2 and the rotating support seat 1 a...

Abstract

The invention provides a retraction avoiding type locking and releasing device. The retraction avoiding type locking and releasing device comprises a supporting unit, a locking unit, a separating unit and a retraction unit. The locked structure is supported on the petal structure of the rotary supporting seat through the adapter plate, the lower edge of the petal structure of the rotary supporting seat is supported on the wedge-shaped structure of the shell, and the locking unit sequentially presses the disengaging spring, the adapter plate and the rotary supporting seat. During unlocking, the split nut is separated, the locking bolt loses limit and is popped out by the release spring, the rotary tension spring pulls the sliding bolt to move, then the rotary supporting seat is stirred to rotate, after the rotary supporting seat rotates by a certain angle, the rotary supporting seat retracts into the shell under the action of the retraction spring, and release is completed. In the on-orbit operation process, the rotating tension spring can continuously tension the rotating supporting seat, and the rotating supporting seat is prevented from rotating. According to the device, a controllable gap can be generated between a locked structure and the rotary supporting base, the working stroke of the locked structure is avoided, and the device is compact in structure, high in space utilization rate, easy and convenient to assemble and good in inclusiveness.

Description

technical field [0001] The invention relates to the technical field of spacecraft structures and mechanisms, in particular to a space locking and releasing device. Background technique [0002] The spacecraft needs a variety of unlocking devices to realize the connection, locking and controllable unlocking functions between the two structures. Most of the locking and releasing devices in the prior art are aimed at the two structures in different installation bases, which need to be completely separated to In the case of normal work, in this case, the locked structure becomes two independently moving objects after unlocking, such as the separation of multi-stage launch vehicles, the separation between satellites and launch vehicles, etc. For the rotating structure on the spacecraft, it needs to be locked during the launch stage to ensure that the structure can withstand the launch mechanical environment. After the orbit is unlocked, the locked structure is still connected to ...
