Problems solved by technology

In these existing technologies, some sleeves are driven by a screw nut mechanism, and the mass is relatively large; some sleeves are deployed by a wire rope, but they are locked by torque / force after fully expanded, and the sleeves can be unlocked and folded when the pulling force is greater than the locking force. However, when the external force is greater than the locking force, the sleeve can also be unlocked, making the work unreliable; other mechanisms can achieve mechanical locking, but it needs to be manually unlocked and then folded or an additional power source is added to replace manual work.

Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0062] The self-unlocking retractable sleeve device of the present invention includes a sleeve part 1, a guide part 2, a driving part 3, a pull wire part 4 and a locking part 5, such as Figure 10 shown. In this embodiment, the present invention will be described with a sleeve part 1 each consisting of an outer sleeve 101, a middle sleeve 102, and an inner sleeve 103, as figure 1 and figure 2 shown. The outer sleeve 101 includes a sleeve A1011, a top sleeve A1012 and a base 1013, the base 1013 is a flange, and the through holes on the base 1013 can be fixed on other designated external devices, thereby realizing Relative fixation between the sleeve device of the present invention and other external equipment. The outer wall of the sleeve A1011 is fixedly connected with the inner wall of the base 1013, and the inner wall of the sleeve A101...

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...
