Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a new type of electronic grip strength meter. Background Art

[0002] At present, there are more and more people who love fitness exercises in society, and there are also more and more users who need to use a grip strength meter that can both exercise and measure the grip strength. However, most of the current grip strength meters on the market are mechanical spring type grip strength meters, that is, the spring is adjusted to a certain scale value, and when holding the handle, it presses the counter button to count the number of exercise times. This is only suitable for exercise because there is no sensor and it cannot accurately measure the grip strength, and the use of an independent counter will increase the cost; there are also some electronic grip strength meters with sensors that can accurately measure the grip strength and display it digitally. However, when measuring small grip strength or counting the number of exercise times, the spring adjustment range between the handle and the sensor is limited, and it will quickly directly squeeze onto the hard sensor. The exercise process lacks the linear change of elasticity, and the experience is not good, and there is also less counting function. This is basically only suitable for measuring grip strength and not suitable for counting exercise times; there are also some electronic grip strength meters that set a compression spring between the rear handle and the sensor to improve the linear change of elasticity during the exercise of the grip strength. However, when not measuring force, the compression spring still squeezes the sensor, which will damage the sensor in the long term and cause inaccurate force measurement; there are also some electronic grip strength meters that use a pressure sensor as a counter and measure grip strength, but when switching to the force measurement mode, it is not switched by pressing a button, but the exercise spring is adjusted to a 0 force value to measure the grip strength. In this way, the adjustment stroke of the spring is long, and when switching to the exercise mode, the spring needs to be adjusted to a certain value to start exercising, which is time-consuming and laborious. Moreover, the display screen is set on the side of the rear handle. For left-handed users who want to measure the left hand grip strength, they simply cannot see the display screen, and the user experience is not good. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a new type of electronic grip strength meter that can display the number of times of exercising with the grip strength meter and can also measure the grip strength.

The control module 7 is electrically connected to the pressure sensing component 5, so that the control module 7 can collect the number of times the pressing convex head 21 presses on the pressure sensing component 5 when switching the exercise mode; and can collect the pressure when the pressing convex head 21 presses on the pressure sensing component 5 when switching the force measurement mode. A display module 6 that is electrically connected to the control module 7 and is used for displaying the data collected by the control module 7 is also provided on the rear handle 1. Thus, when using this new type of electronic handgrip for exercise or measuring grip strength, when switching to the exercise mode, the display module 6 can display the number of times the pressing convex head 21 presses on the pressure sensing component 5, so as to assist the user in exercising and whether the exercise reaches the standard; when switching to the force measurement mode, the display module 6 can display the pressure value acting on the front handle 2 and the rear handle 1, thereby measuring the grip strength of the user.

[0023] In this solution, the display module 6 includes a display screen 61 provided at the upper end of the rear handle 1 and on its rear side, that is, the display screen 61 is provided on the side facing the user, so that the user can see the display module 6 clearly whether using this new type of electronic handgrip with the left hand or the right hand, thus facilitating the user to use and enhancing the user experience.

[0024] In this solution, the control module 7 includes a control main board 71 provided on the rear handle 1 and a switching button 72 provided on the rear handle 1 and connected to the control main board 71.

[0025] In this solution, the adjusting mechanism 4 includes a limiting groove 41 provided at the upper end of the front handle 2, a special-shaped screw 42 rotatably arranged in the limiting groove 41, a special-shaped nut 43 arranged on the special-shaped screw and threadedly engaged with the special-shaped screw, a limiting component 44 provided in the limiting groove 41 and allowing the special-shaped screw 42 to move back and forth, and a knob 45 connected to the front side of the special-shaped screw 42 and capable of driving the special-shaped screw 42 to rotate. A connecting head 431 connected to the spring 3 is provided at the upper end of the special-shaped nut 43. Further, the limiting component 44 includes a limiting pin shaft 441 provided in the limiting groove 41 and behind the special-shaped screw 42, and the special-shaped screw 42 is provided with an annular groove 442 engaged with the limiting pin shaft 441, so that the special-shaped screw 42 can only rotate in the limiting groove 41.

[0026] In this solution, an opening groove 11 is provided on the front side of the rear handle 1, and the upper end of the front handle 2 is hinged below the opening groove 11. Further, a connecting pin shaft 12 is provided in the opening groove 11 and above it, a connecting hole 432 is provided on the connecting head 431, one end of the spring 3 is connected to the connecting pin shaft 12, and the other end is connected to the connecting hole 432. In this way, by rotating the knob 45, the special-shaped nut 43 can be driven to move forward, thereby pulling out the spring 3 connected thereto, so as to adjust the force of pressing the front handle 2 against the rear handle 1, and thus adjust the size of the grip force.

[0027] In this solution, the pressure sensing component 5 includes a through hole 51 provided on the front side of the rear handle 1, a pressure sensor 52 provided in the rear handle 1 and electrically connected to the display screen 61, and a sensing head 53 provided on the pressure sensor 52 and located in the through hole 51. In this way, after the pressing protrusion 21 presses on the sensing head 53 and continues to apply pressure, at this time the pressure sensor 52 can measure the magnitude of the applied pressure, and then combined with the magnitude of the force of pressing the front handle 2 against the rear handle 1, it is fed back to the control main board 71 and the grip force at this time is displayed on the display screen 61.

[0028] In this solution, the rear handle 1 is provided with a power supply 13 for supplying power to the display screen 61.

When exercising, press the switching button 62 to switch to the exercise mode, then rotate the knob 45 to adjust the grip force to an appropriate size, hold and press the front handle 2 so that the pressing protrusion 21 on the front handle 2 presses on the sensing head 53 on the rear handle 1, and then release it. At this time, it will be fed back to the display screen 61, and the exercise count will be increased by 1. Repeat this process of gripping and releasing to accumulate and increase the count, and display it through the display. And if the pressing protrusion 21 on the front handle 2 does not press on the sensing head 53 on the rear handle 1, the exercise count will not be accumulated, making the exercise more standard.

[0031] When measuring the grip force, press the switching button 62 to switch to the force measurement mode, then rotate the knob 45 to adjust the grip force to the scale line N1 at a set fixed elastic force size, which can be 5 kg or 10 kg, that is, the force value required to just press the pressing protrusion on the front handle 2 against the sensing head 53 on the rear handle 1 at this time is N1. After that, when continuing to apply force to measure the grip force, the pressure sensor 52 on the rear handle 1 will sense a new pressure magnitude N2, and thus the control main board 71 will display the sum of the grip force values N1 + N2 on the display screen 61, and the user can observe the grip force magnitude at this time.
