Abstract
The invention discloses an instrument for measuring human body finger pressing force. The instrument comprises a box, a box cover, a finger pressing plate, a finger pressing display device, a lever, a pressure sensor, a rotary shaft, a power supply and a digital conversion circuit, wherein the lever, the pressure sensor, the rotary shaft, the power supply and the digital conversion circuit are located in the box, the box cover is rotationally connected with the box through hinges, the finger pressing display device is disposed on the box cover and comprises a lamp band and a display screen, the finger pressing plate is disposed on the surface of the box, the right lower portion of the finger pressing plate presses against one end of the lever, the other end of the lever is connected with the rotary shaft, and the middle position, located at half of the length of the lever, of the lever presses against the pressure sensing face of the pressure sensor. The instrument has the advantages that finger pressing force can be displayed visually, and the instrument can be used as an interesting measuring instrument for a science exhibition hall.
Description
Technical field
The present invention relates to a kind of device for measuring force, be specially a kind of human finger pressing force measuring instrument measuring finger pressure size.
Background technology
In daily life, people often need to go to press various article with finger.Different people, the size of its finger strength is different.The size of finger strength needs in the sports item such as basketball, shot to carry out emphasizing exercise and test to athlete.In hospital, the patient injured to hand, needs to judge its recovery situation by the test of finger strength size sometimes.At present, the instrument directly perceived testing and compare finger pressure size is lacked.
Summary of the invention
The technical problem to be solved in the present invention, is to provide the human finger pressing force measuring instrument of the finger presses power size of a kind of convenient test and display people directly perceived.
In order to solve the problems of the technologies described above, the present invention is by the following technical solutions: a kind of human finger pressing force measuring instrument, comprise box body, lid, acupressure probe, finger pressure display device, lever, pressure transducer, rotating shaft, power supply, digital conversion circuit, lid is rotationally connected by hinge and box body, lever, pressure transducer, rotating shaft, power supply, digital conversion circuit is all located at tray interior, power supply is by wire and pressure transducer, digital conversion circuit is connected with finger pressure display device electricity, digital conversion circuit is connected with finger pressure display device electricity with the outfan of pressure transducer respectively, it is characterized in that: described finger pressure display device is located on lid, and finger pressure display device comprises light bar and display screen, acupressure probe is located at box surface, is pressed against one end of the lever in box body immediately below acupressure probe, and the lever other end is connected in rotating shaft, and its intermediate part 1/2 lever length position is pressed against on the pressure-sensitive face of pressure transducer.
Described light bar is made up of LED.
Described pressure transducer is semiconductor pressure sensor.
The present invention is when testing finger pressure, finger force pressing acupressure probe, act on pressure transducer after utilizing lever principle less finger presses power to be amplified, pressure transducer output corresponding signal by outputting to finger pressure display device after digital conversion circuit, light bar represents finger pressure size by the quantity of bright light, and display screen is by Digital size display finger pressure size.Structure of the present invention is simple, practical and convenient, is easy to carry, intuitively can shows the size of finger pressure, and can be used as entertaining gauge in scientific and technological museum.
