Description

Technical Field

[0001] This utility model relates to the field of racket testing equipment, specifically to a racket weight leveling testing machine. Background Technology

[0002] A racket weight balance tester, also known as a racket weight balance tester, is used to test the weight, balance, and length of badminton or tennis rackets. A racket with its balance point closer to the head is called "head-heavy," while one with its balance point closer to the handle is called "head-light." The balance point is typically measured from the bottom of the racket upwards, in centimeters or inches. According to the principles of mechanics, weight has a direct proportionality to the feel of the swing, while the balance point has a square-proportional proportionality to the feel of the swing. Head-heavy rackets, due to their greater head inertia, produce more power in the shot but slightly less swing agility. They are more suitable for offensive play and are also a good choice for players with less power, as the lower head weight makes it easier to hit the shuttlecock to the backcourt.

[0003] Chinese Patent No. CN 119124460A discloses a racket weight leveling test machine, which includes a machine body. An electric guide rail is provided in the middle of the upper end of the machine body. A scale is provided on one side of the upper part of the electric guide rail. A straightening frame is slidably fitted above the electric guide rail. A length detection sensor is installed on one side of the straightening frame. A weight detection sensor is installed in the middle of the upper part of the machine body. Two positioning seats are slidably fitted around the periphery of the weight detection sensor.

[0004] Although the above application can perform weight balance testing on rackets, the structure can only be adapted to measuring longer rackets because the straightening frame and racket head fixing seat can only be adjusted in length by the straightening frame. This limits the measurement of rackets of different lengths on the same testing machine, resulting in slow measurement speed and low efficiency. Utility Model Content
