Abstract

The invention provides a joint type portable feet limiter comprising a limiting pedal, a yaw adjusting joint mechanism, a deflection adjusting joint mechanism and a pitch adjusting joint mechanism. The yaw adjusting joint mechanism comprises a yaw indexing positioning unit. The limiting pedal is mounted on the upper portion of the yaw adjusting joint mechanism. The deflection adjusting joint mechanism is connected to the lower portion of the yaw adjusting joint mechanism. The deflection adjusting joint mechanism comprises a deflection indexing positioning unit. The pitch adjusting joint unit is connected to the lower portion of the deflection adjusting joint mechanism and comprises a pitch indexing positioning unit. A loading limiting mechanism, used for overload protection, and a rapid mounting connector mechanism, used for connecting with other equipment, are mounted on the pitch adjusting joint mechanism. By the use of the feet limiter, a supporting platform is provided for a spaceman to perform real-time pose adjustment in space, operation motions for large-angle pose adjustment are fewer, and physical exhaustion of the spaceman is avoided.

Description

technical field [0001] The invention belongs to the field of astronaut appliances, and in particular relates to a portable foot stopper. Background technique [0002] Foot restraints are important auxiliary equipment for astronauts to complete extravehicular work, and play a key role in the extravehicular work systems of space stations and space shuttles. When astronauts perform maintenance, installation and other operations in space, they can only perform work that requires only one hand and the operating force is less than 5N in the floating state. In space, most work cannot be done while floating. Therefore, a foot-limiting device is needed to provide a stable support platform to assist astronauts in performing related extravehicular activities, and the platform can control its own working posture in real time, so as to complete various complex tasks smoothly and efficiently. [0003] The General Design Department of Beijing Aerospace Vehicles has applied for a patent o...
