Abstract
The utility model belongs to field of sports equipment, relate to a kind of survey table tennis net height device, it is characterized in that: be totally made up of three identical scales, wherein each scale is formed by with lower component: scale side is provided with stingy hand, described scale and supporting plate are connected by axle is dynamic, described supporting plate side is provided with spacing described scale side edge, described supporting plate be provided with below playback described scale under edge, three described supporting plates embed in left billiard table inner face three grooves respectively, respectively be fastenedly connected by two sunk screws, moving described stingy hand makes three described scales uprightly delineate net height directrix, described net height directrix and daylight opening DLO are from being 15.25 centimetres, described net height directrix is parallel with top line of the net.Compared with this device is high with existing ruler special ruler survey grid, its beneficial effect is: volume is little, lightweight, cost is low, and convenient operation is easily used, and test process is relatively time saving and energy saving.
Description
Technical field
This patent belongs to field of sports equipment, and particularly one surveys table tennis net height device.
Background technology
Tennis competition rule 1.2.3 regulation " net upper end distance table top 15.25 centimetres." usually with one high for ruler survey grid need in platform, the repeated multiple times adjustment net in both sides, could realize holding apart from table top 15.25 centimetres of requirements on the net, said process is wasted time and energy relatively.With three special rulers in platform, 3, both sides survey grid height is comparatively reasonable, but because of three, ruler is inconvenient to carry relatively, be seldom used, now lack a kind of easy survey grid height device.
Utility model content
In order to Problems existing in above-mentioned background technology can be solved preferably, the object of this patent is to provide a kind of survey table tennis net height device, the technical scheme taked is, totally be made up of three identical scales, wherein each scale is formed by with lower component: scale side is provided with stingy hand, described scale and supporting plate are connected by axle is dynamic, described supporting plate side is provided with spacing described scale side edge, described supporting plate be provided with below playback described scale under edge, three described supporting plates embed in left billiard table inner face three grooves respectively, respectively be fastenedly connected by two sunk screws, moving described stingy hand makes three described scales uprightly delineate net height directrix, described net height directrix and daylight opening DLO are from being 15.25 centimetres, described net height directrix is parallel with top line of the net.
Compared with this device is high with existing ruler special ruler survey grid, its beneficial effect is: volume is little, lightweight, cost is low, and convenient operation is easily used, and test process is relatively time saving and energy saving.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 is that a kind of master surveying table tennis net height device looks sketch, is also survey grid high state simplified schematic diagram;
Fig. 2 is that sketch is looked on a left side of Fig. 1;
Fig. 3 is the diagrammatic top view of Fig. 1;
Fig. 4 is the playback state simplified schematic diagram of Fig. 1;
Fig. 5 is the partial enlargement simplified schematic diagram of Fig. 3.
Embodiment
With reference to accompanying drawing, this programme is totally made up of three identical scales, wherein each scale is formed by with lower component: scale 2 side is provided with stingy hand 3, described scale and supporting plate 6 are connected by axle 10 is dynamic, described supporting plate side is provided with spacing described scale side edge 11, described supporting plate be provided with below playback described scale under edge 9, three described supporting plates embed in left billiard table 1 inner face three grooves 8 respectively, respectively be fastenedly connected by two sunk screws 5, moving described stingy hand makes three described scales uprightly delineate net height directrix 4, described net height directrix and daylight opening DLO are from being 15.25 centimetres, described net height directrix is parallel with top line of the net 7.
When using this device, upwards move each described stingy hand, make left side, centre, right side described scale half-twist be against described side edge, making each described net height directrix parallel with described top line of the net, is 15.25 centimetres to measure net height, as shown in Figure 1.After measurement, promote each described stingy hand downwards, under each described scale, half-twist is against described lower edge, as shown in Figure 4.
