Abstract

The invention provides a self-unlocking sleeve device capable of being unfolded and folded, which belongs to the technical field of machinery and comprises a sleeve portion, a guide portion, a driving portion, a pull wire portion and a locking portion. The sleeve portion at least comprises three sleeve structures, and the pull wire portion comprises a steel wire rope and a pulley system. The driving portion is utilized to drive the pull wire portion to enable sleeves to be unfolded or folded along the guide portion. The locking portion achieves mechanical self locking when the sleeves are completely unfolded, and unlocking, folding and unfolding of the sleeves share one set of driving device. The self-unlocking sleeve device has the advantages of simplifying the driving device and the operation process, being simple in structure, small in mass, reliable in locking and capable of achieving self-unlocking.

Description

technical field

[0001] The invention belongs to the field of mechanical technology, and relates to a self-unlocking and retractable sleeve device, which specifically refers to that the device is driven by a wire rope to expand and contract the sleeve, and can be mechanically locked when it is fully extended, and the same set of driving device realizes unfolding, locking, unlocking and retracting . Background technique

[0002] The expandable mechanism is easy to carry and transport when it is in a folded state, and can work effectively when it is in an unfolded state, and is widely used in fields such as mobile communication and space science. The expandable sleeve device is a linear motion expandable mechanism, which is often used in rod antenna extension mechanisms or as supports for other mechanisms. Aiming at different purposes, a variety of deployable sleeve devices have been produced, such as reference [1]: Cong Qiang. ERM and its application in satellite antenna depl...
