Embodiment 1

[0030] According to the implementation example, the outer sleeve 5 is designed as a rectangular body, and the ejection mechanism is designed with 4 sets of symmetrical sleeve compression components, and 2 pull pins 2 are designed, which are symmetrically distributed in the long side direction of the outer sleeve 5 . The sleeve assembly 3 includes a sleeve 7, a sleeve 8, a sleeve 9, and a sleeve 10 that are sequentially slid from bottom to top, and the push plate 6 is fixedly connected to the sleeve at the top of the sleeve 10. , the mounting base 1 is fixedly connected to the sleeve at the bottom of the sleeve 7 .

Abstract

The invention discloses a sleeve type spring push-out mechanism which can effectively solve the problems of uncontrollable bending, offset deformation and the like in the compression process of a long spring. The multi-section sleeve structure is arranged on the inner side of the compression spring in a sleeving mode, the compression spring drives the sleeve to contract in the compression process, and meanwhile due to the existence of the sleeve structure, uncontrollable bending and deviation deformation of the spring in the compression process are avoided; after unlocking, the compression spring drives the multi-section sleeve to unfold and restore deformation, and in the unfolding process, due to the existence of the sleeve structure, the spring is limited to unfold along the sleeve structure; the design of the sleeve structure plays a role in limiting and positioning at the same time, after the sleeve is completely unfolded, the residual elastic force of the compression spring continues to support the sleeve, and up-down limiting self-locking of the sleeve structure is completed.

Description

technical field [0001] The invention belongs to the field of space placement, and in particular relates to a sleeve-type spring push-out mechanism. Background technique [0002] At present, there are mainly the following engineering realization forms for the release and throw of space products: pyrotechnic product release, airbag release, electric release and spring energy storage release, etc. The advantages and disadvantages of each are analyzed and compared. [0003] 1. Release pyrotechnics. The pyrotechnic product has the advantages of high energy and high reliability. Through the combustion of the pyrotechnic product, a high pressure can be formed in the closed cavity instantly, and the object to be released will be squeezed to move forward. At the same time, for the release of space products, pyrotechnic products also have disadvantages such as large volume, poor product consistency, polluting gas emissions, and high reaction force. [0004] 2. The airbag is released...
