A grip strength rehabilitation training measuring device

Abstract

This invention discloses a grip strength rehabilitation training and measurement device. Two grip strength plates are symmetrically arranged and connected by a connecting piece, forming a closed spatial structure. A square base is placed inside the cavity, with the base positioned at the center. A sensor is located at the center of the base, and fixed rods are connected to both sides of the sensor. The fixed rods are placed on the base, and a support spring is installed inside each fixed rod. One end of the support spring is connected to the sensor, and the other end is connected to a telescopic rod. The other end of the telescopic rod is connected to a buffer spring, which passes through a spring hole and connects to the grip strength plate. Several limiting springs are provided on one side of the telescopic rod, and the limiting springs are movably connected to locking pins. Support rods are located at corresponding positions on the locking pins, and the support rods are fixedly connected to the fixed rods. This invention changes the radius of the entire device by adjusting the relative positional relationship between the telescopic rod and the fixed rod to accommodate different hand shapes or for finger strength measurement and training.

Description

[0001] The invention relates to a training and measuring instrument, in particular to a grip strength rehabilitation training and measuring device. Background Art

[0002] With the continuous improvement of the quality of life, people's requirements for physical training and rehabilitation are also constantly increasing. At present, most of the physical training devices for grip strength use the natural properties of materials or objects such as springs, rubber, and weights for physical training, and rely on manual statistics of the training process and results. There are many diseases that can cause decreased grip strength and uncoordinated single finger movements. The current grip training equipment and finger training equipment are mostly different devices that cannot achieve the unification of grip and finger strength functional rehabilitation training, which increases the diversity of grip and finger strength rehabilitation training equipment and increases training costs. At the same time, the existing devices also use the natural properties of materials or objects such as springs, rubber, and weights for physical training, and rely on manual statistics of the training process and results. When using devices with the same parameters for grip and rehabilitation training, some trainees will not adapt to the training due to their different hand shapes, grip strength, and finger strength, which will affect training compliance and training results.
