Problems solved by technology

[0008] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a new type of locking device. With this locking device, the thick and thin oblique rods will not increase the friction force during the sliding process, and the oblique rods will not be deformed. The risk of the lower locking device being locked in place before the antenna is deployed, and the compensation device has a simple structure and high reliability

Embodiment Construction

[0030] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0031] Such as figure 1 Shown is an exploded view of the structure of the new locking device of the present invention. It can be seen from the figure that the locking device includes a thick joint 1, an adjustable joint 2, a thin joint 3, a retaining ring 4, and a shrapnel 5; wherein the thick joint 1 and the thin joint 3 are connected with the external device Connection; the adjustable joint 2 is set on the outer wall of the thick joint 1; the adjustable joint 2 includes a locking groove 6, and the thin joint 3 includes a retaining ring slot 10 and a guide cylinder 9; the retaining ring 4 is limited by the guide cylinder 9 of the thin joint 3 The adjustable joint 2 is fixedly connected with the thin joint 3 through the locking groove 6 and the retaining ring 4; the shrapnel 5 is fixed on the inner wall of the retaining ring 4, and the adjustabl...

Abstract

The invention relates to a novel locking device, and relates to the field of reliable locking of spatial mechanisms. The novel locking device comprises a thick joint, an adjustable joint, a thin joint, a retainer ring and spring plates, wherein the thick joint and the thin joint are used for being connected with an external structure; and the thick joint and the adjustable joint can meet an adjustable overall length of the device. The invention creatively designs the novel locking device, in an opposite sliding expansion process of diagonal rods of an antenna, no extrusion is generated between the outer wall of the thin diagonal rod and the inner wall of the adjustable joint; the friction force of sliding expansion of the diagonal rods is reduced; the locking device is simple in structure and ingenious in design; and when the thick and thin diagonal rods of the antenna oppositely slide to complete expansion, the retainer ring provided by the invention can enter a locking inclined plane of the adjustable joint and a locking grove to finish locking.

Description

technical field [0001] The invention relates to the field of reliable locking of space mechanisms, in particular to a novel locking device. Background technique [0002] With the advancement of aerospace technology, spaceborne reflector antennas are developing in the direction of large aperture and high precision. Limited by the envelope of the rocket when the satellite is launched, the development of large-scale deployable antennas has become an effective way to solve the contradiction. [0003] Large-scale deployable antennas refer to space-borne large-scale antennas with the function of space deployment, that is, the satellites are installed on the satellite in a folded form in the launch state, and after the satellites enter orbit, they are deployed under the control of ground commands to reach the working state. Because it involves many professional fields and is difficult to develop technology, it is an important symbol to measure the technical level of satellite anten...
