Description
Technical field
This utility model relates to sports equipment field, refers in particular to a kind of table tennis table spring tester.
Background technology
Prior art 201420345798.9 discloses a kind table tennis table spring tester, described tester body
For tubulose, tester body is provided with some scale grooves, and the top of tester body is provided with locating ring, is positioned at below locating ring
Tester body is provided with baffle plate slot, is provided with baffle plate in baffle plate slot；During work, table tennis is placed on baffle plate, the most fast
Speed extracts baffle plate out, allows table tennis free-falling, observe scale groove see table tennis after upspringing whether in the range of the spring of standard, by
In by eye-observation, and cannot ensure human eye and scale groove level, the data being easily caused test are inaccurate.
Utility model content
This utility model purpose is to provide a kind of table tennis table spring tester to overcome the deficiencies in the prior art, no
Only simple in construction, easy to use, and measuring accuracy is high.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of table tennis table spring tester, comprises
The base of horizontal positioned, for showing the display of jumping height value；Be provided with instrument connection on described base, on described base
The Fibre Optical Sensor of at least one it is provided with at the top edges of instrument connection；The guiding of vertically placement it is additionally provided with on described base
Bar；The slide block that can slide up and down and be positioned by bolt it is provided with on described guide post；The head of described slide block is provided with and surveys
Prospect hole concentric and for hold table tennis vacuum inhale ball；Described display is connected with Fibre Optical Sensor by wire.
Preferably, described guide post is provided with scale.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
Table tennis table described in the utility model spring tester is detected by Fibre Optical Sensor, is not only simple in structure, makes
With convenient, and measuring accuracy is high.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of table tennis table described in the utility model spring tester.
Wherein: 1, base；11, instrument connection；2, Fibre Optical Sensor；3, guide post；31, scale；4, slide block；5, vacuum is inhaled
Ball；6, bolt；7, display.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Accompanying drawing 1 is table tennis table described in the utility model spring tester, comprises the base 1 of horizontal positioned, display
7；Being provided with instrument connection 11 on described base 1, on described base 1, above instrument connection 11,50mm edge is provided with three water
The flat Fibre Optical Sensor 2 being spaced apart；The guide post 3 vertically placing and being provided with scale 31 it is additionally provided with on described base 1；Institute
State and on guide post 3, be provided with the slide block 4 that can slide up and down and be positioned by bolt 6；The head of described slide block 4 is provided with and tests
Hole 11 concentric and for hold table tennis vacuum inhale ball 5；Described display 7 is connected by wire and three Fibre Optical Sensors 2
Connect, for showing the jumping height value that Fibre Optical Sensor 2 is measured.
During use: be first placed on court by base 1, then adjust the height distance table tennis table 300mm of slide block 4,
Holding table tennis is inhaled ball 5 by vacuum, then extruding vacuum inhales ball 5, makes table tennis fall under gravity, passes through
Three Fibre Optical Sensors 2 enter instrument connection 11 and are built on court, and now three Fibre Optical Sensors 2 are by first bounce
Cover three Fibre Optical Sensors and give display 7 to the time falling to covering three Fibre Optical Sensors for the second time by wire, and
The time of reception is changed into jumping height value by following formula by display 7 automatically；
The computing formula of jumping height H:
In formula: H be jumping height (mm), g be acceleration of gravity (mm/s2), t is that first bounce covers three optical fiber biographies
Sensor falls to covering the time (s) of three Fibre Optical Sensors to second time, the distance that 50 is Fibre Optical Sensor to court
(mm)。
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
Table tennis table described in the utility model spring tester is detected by Fibre Optical Sensor, is not only simple in structure, makes
With convenient, and measuring accuracy is high.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.
The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
