Embodiment Construction
[0023] Such as figure 1 As shown in the figure, a reciprocating operation type waste compression device with a large force ratio includes an operating handle 1, a driving pawl 2, a driving ratchet 3, a bevel gear pair 4, a ball screw pair 5, a compression piston 6, and a self-locking pawl 7. Self-locking ratchet 8;
[0024] The driving pawl 2 is connected to one end of the operating handle 1, the driving pawl 2 is matched with the driving ratchet 3, the driving ratchet 3 is coaxial with one bevel gear in the bevel gear pair 4, and the pair of bevel gears in the bevel gear pair 4 are orthogonal Layout, the other bevel gear is connected to the compression piston 6 through the ball screw pair 5, the self-locking ratchet 8 and the ball screw pair 5 have a total transmission chain, and the self-locking ratchet 8 is matched with the self-locking pawl 7.
[0025] The present invention adopts a double ratchet mechanism to realize the reciprocating drive and position locking in the co...

A reciprocating operation waste compression device with a large boost ratio, including an operating handle (1), a driving pawl (2), a driving ratchet (3), a bevel gear pair (4), a ball screw pair (5), a compression Piston (6), self-locking pawl (7), self-locking ratchet (8); the driving pawl (2) is connected to one end of the operating handle (1), and the driving pawl (2) is matched with the driving ratchet (3), The driving ratchet (3) is coaxial with one bevel gear in the bevel gear pair (4), and the pair of bevel gears in the bevel gear pair (4) are arranged orthogonally, and the other bevel gear is connected and compressed by a ball screw pair (5). The piston (6), the self-locking ratchet (8) and the ball screw pair (5) share a transmission chain, and the self-locking ratchet (8) cooperates with the self-locking pawl (7); Continuously compressed, the double ratchet mechanism has a simple structure and does not need to use a complicated clutch mechanism.
Description
technical field [0001] The invention relates to a waste compression device. Background technique [0002] With the continuous development of manned spaceflight missions and the steady progress of space station construction tasks, the problem of space station waste disposal has become increasingly prominent. In order to reduce the storage space occupied by waste, it needs to be compressed to meet the long-term on-orbit space station. Operational waste storage needs. [0003] Due to the wide variety of space station waste and different load characteristics, astronauts in orbit have an increasingly strong demand for compression devices that can adapt to waste with different force load characteristics. It is urgent to develop waste according to the progress of my country's space missions. compression device. [0004] Based on the energy constraints of the space station and considering the needs of astronauts for on-orbit exercise, the waste compression device is a mechanical hu...
