Description
Technical field
The utility model belongs to the sports field, particularly a kind of table tennis and elasticity of table tennis bat tester that uses when being used to detect table tennis and elasticity of table tennis bat.
Background technology
The elasticity of base plate of ping-pong bat is to weigh the most important index of table tennis bat quality.Detecting the flexible method of base plate of ping-pong bat is: highly freely fall table tennis from 300mm, after base plate of ping-pong bat was fallen in observation, the height of first spring, the height of this first spring were exactly the main foundation of weighing base plate of ping-pong bat elasticity size; The elasticity of table tennis also is to weigh the most important index of table tennis quality, detects the flexible method of table tennis and is: highly freely fall the different quality table tennis from 300mm, fall on the same table top, observe the height of table tennis first spring.The instrument that existing when test adopts mainly is ruler, anchor clamps and video camera etc., can not survey base board of table tennis bat elasticity and can survey the flexible necessary instrument of table tennis again owing to still have, and makes test process loaded down with trivial details, accurate inadequately.
Summary of the invention
In order to overcome above-mentioned deficiency; The utility model proposes a kind of table tennis and elasticity of table tennis bat tester; This instrument platen is provided with lamp, chi frame and camera; Can detect the elasticity of table tennis, can detect the elasticity of table tennis bat again, can reach and simplify test process and the purpose that improves the accurate testing degree.
The technical scheme that the utility model adopted is: a kind of table tennis and elasticity of table tennis bat tester; This instrument main frame is connected through gluing riveted with chi frame lower end by platen right front portion upper end; Chi frame bottom and following vernier socket; Following vernier sidepiece is provided with lower locating device, and following vernier is anterior to be welded with the geometrical clamp rear end; Chi frame top and last vernier socket, last vernier front portion is provided with steady arm, a last vernier sidepiece and a rod rear end welding, pole front end and the welding of clamp rear end; Platen left forward upper end is connected through screw with the battery case lower end with lamp box; Platen rear upper end and camera bottom connect to form through screw.
Be provided with lamp in the said lamp box, lamp box side lower part and the welding of battery case sidepiece, battery case top is provided with switch, and battery is equipped with in battery case inside.
Said chi frame front and side are respectively equipped with several pilot holes, and chi frame front, back and two sides are equipped with scale mark.
The elasticity of said platen is 240～260mm, and the uniform elastic degree is≤5mm, friction factor is≤and 0.3.
Said camera bottom is connected with the lead front end, and the lead rear end is connected with plug.
Table tennis and elasticity of table tennis bat tester are simple in structure, processing ease, and the elasticity of platen meets each item elastic index of international standard table tennis table, can measure the flexible size of table tennis accurately; The chi frame both can play the support effect, can play the scale effect again, and chi frame front, back and two sides are equipped with scale mark and are convenient to observe the position that table tennis is upspring.The clamp that chi frame top connects is table tennis fixedly, and is easy to operate during test, needs only the back handle of pinching out clamp with hand, and table tennis can produce the movement of falling object.The geometrical clamp that chi frame bottom connects can make base plate of ping-pong bat maintenance level and fixing, and table tennis is fallen and is difficult for making its generation to rock on the base plate of ping-pong bat, and the bounce-back track that produces is difficult for departing from, and has improved the accurate degree of test; Lamp in the lamp box not only is convenient to observe the rebound of table tennis, also can increase the effect of shooting with video-corder, and the lead of camera connects computer can analyze anti-pumping performance; This instrument not only is fit to manufacturer and scientific research institutions and carries out the detection and the analysis of table tennis and table tennis bat quality, also is fit to businessman and personal user and when selecting table tennis and table tennis bat, adopts.The application of this instrument has practical significance to improving table tennis and elasticity of table tennis bat test effect.
