Abstract

The invention discloses a four-finger exoskeleton bending and grabbing power mechanism of a hand pressure reduction machine exoskeleton device. The four-finger exoskeleton bending and grabbing power mechanism comprises a palm containing barrel and a minitype pneumatic muscle tendon. A thumb stretching opening is formed in the left side or the right side of the bottom of the palm containing barrel. A little finger exoskeleton assembly, a ring finger exoskeleton assembly, a middle finger exoskeleton assembly and an index finger exoskeleton assembly which are located on the front side of the palm containing barrel are in transmission connection with the top of the palm containing barrel side by side through single-drive multi-rod mechanisms correspondingly. A knuckle bending, pulling and fastening mechanism is arranged between each of third knuckle sleeves of the little finger exoskeleton assembly, the ring finger exoskeleton assembly, the middle finger exoskeleton assembly and the index finger exoskeleton assembly and the minitype pneumatic muscle tendon. The four-finger exoskeleton bending and grabbing power mechanism is specially designed for a transport worker, and force of the hand of the transport worker is fully relieved; and the weight of carried weights is greatly improved, and the efficiency of cargo handling is improved. In addition, the four-finger exoskeleton bending and grabbing power mechanism can be used for medical apparatus and instruments, and better and more comprehensive rehabilitation of the hand and the wrist of a patient is facilitated.

Description

technical field [0001] The invention relates to a decompression device for carrying heavy objects, in particular to a four-finger exoskeleton bending and grasping power mechanism of a hand decompression mechanical exoskeleton device. Background technique [0002] For porters who often carry goods, such as movers and construction workers, they often have to grasp the goods with their hands. The four fingers except the thumb are particularly stressed. Long-term handling operations will cause fingers Injuries to bones and wrist joints will basically disable the hands when they get older. There is currently no device on the market that is specially adapted to be worn by porters and is used to relieve hand pressure. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a four-finger exoskeleton bending and grasping power mechanism of a hand decompression mechanical exoskeleton device with compact structure, stron...
