Description

Grip strength measuring device

The invention relates to a device that has both the functions of sports equipment and the function of measuring grip strength. More particularly, it refers to a device for measuring grip strength that can replace elastic elements.

A commonly used grip strength measuring device mainly includes two clamping parts and an elastic element. The elastic element is provided in the two clamping parts. The user can hold the two clamping parts and use the hand to measure the elastic element. The gripping force of the two clamping parts can be increased to increase the gripping strength of the hand.

However, the conventional grip force measuring device requires the two clamping parts to be held inside the palm, and the elastic element is also disposed inside the palm. The holding method makes it difficult for the user to apply force, and because During use, the elastic element is gradually compressed by the two clamping parts and the elastic force will gradually increase. When the user relaxes after reaching a certain level of force, the elastic restoring force generated by the elastic element will often cause the grip strength to be measured. The device pops open instantly, making it impossible for the user to hold it and falls out of the user's hand. In addition, since the elastic force of the elastic element is fixed, when the user needs to increase the elastic force after use, a new grip force measuring device needs to be purchased, causing the user inconvenience of increasing storage space.

The invention provides a grip strength measuring device, a first unit having a base plate and a first grip; the base plate is provided with two through holes at intervals; the first grip has two position rods vertically disposed on the base plate , and is located outside the two perforations. A handle bar is disposed across the top of the two-position rod; a second unit has a pressure plate and a second handle; the second handle has two connected The rod is arranged vertically on the pressure plate, and the two connecting rods pass through the holes in the base plate. The ends of the two connecting rods are connected with a limiting rod; the second grip is arranged on the inside of the first grip. ; And the limit rod will be limited in the first handle to limit the moving position of the second handle; an elastic body is elastically disposed between the pressure plate and the base plate. When the pressure plate and the base plate When the position is close, an elastic force can be generated.

The invention provides a grip strength measuring device that can produce different grip strength options by replacing elastic bodies with different elastic forces, and the second grip will be limited by the first grip, so the second grip will be limited by the first grip. The moving position of the second grip will be limited, which can relatively limit the degree of pressing of the elastic body, thereby preventing the elastic body from generating excessive elastic force due to excessive force.
