Strength training device for double upper limbs

Abstract

The invention discloses a strength training device for double upper limbs. The device comprises a base, a left upper limb connecting mechanism and a right upper limb connecting mechanism, a right rotating shaft is fixed on a right handle rod of the right upper limb connecting mechanism; the right rotating shaft fixes a right oscillating rod; one L-shaped side of a right bent shaft is rotationallyand slidably connected with the right oscillating rod; the other L-shaped side of the right bent shaft is rotationally and slidably connected with the right end of a swing block; a transmission shaftis fixed in the swing block; a middle bevel gear is meshed with two bevel gears; the two bevel gears are fixed on an intermediate shaft through a one-way bearing, so the unidirectional rotation of theintermediate shaft is realized; two ends of the intermediate shaft are respectively connected with crankshafts; each crankshaft forms two crank sliding block mechanisms; the crank of each slider-crank mechanism is gradually lengthened, a groove is formed in the upper portion of the sliding block, the process that a ball gradually rises to the left end sliding block in the groove of the sliding block and then rolls into the groove of the right end sliding block along a ball channel is achieved, fun is increased for the training process, and meanwhile a trainee visually sees the exercise training amount.

Description

technical field [0001] The invention relates to a double upper limb strength training device, which belongs to the technical field of rehabilitation medical equipment. Background technique [0002] With the affluence of life, our quality of life is also constantly improving. Healthy people need to exercise to improve their health index, and some patients due to stroke, traumatic brain injury, and upper limb trauma need exercise more urgently to improve their quality of life. The current training equipment is large Some of them are relatively simple in the training process, and there is no fun to speak of, while a small part is connected with entertainment display devices. This part of the trainer is not only complicated in structure and high in cost, but also requires professionals to set up and maintain it. The economic cost is that many trainers unbearable. [0003] In this application, one side of the upper limb drives the L-shaped bent shaft, the bent shaft drives the s...
