Abstract
A kind of device of 3 detection table tennis net height, it is characterized in that: be totally made up of three same detection chis, wherein each detection ruler is formed by with lower component, neodymium iron boron strong magnetic piece embeds in the middle end side surface of right, also the middle end side surface of left can be embedded, connect standpipe above rod support below it to be adsorbed by neodymium iron boron strong magnetic piece, vertical rod lower thread is threaded through nut, riser upper threaded hole realizes connecting, vertical rod upper lateral riveted joint straight pin, screw standpipe to make below its straight pin, to touch online end distance table top 15.25 centimetres, by screw on nut, standpipe and vertical rod are fixed.Move described rod support to thruster, make it depart from neodymium iron boron strong magnetic piece adsorption range, remove detection ruler.Compared with these 3 devices detecting table tennis net height and existing ruler, special ruler survey grid are high, its beneficial effect is: small in volume cost is low, is convenient for carrying operation and is easily used, and test process is relatively time saving and energy saving.
Description
Technical field
This patent belongs to field of sports equipment, particularly a kind of device of 3 detection table tennis net height.
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 on the net apart from table top 15.25cm requirement, said process is wasted time and energy relatively.With three special rulers in platform, 3, both sides survey grid height is comparatively reasonable, but is inconvenient to carry relatively large for ruler volume because of three, be seldom used.
Summary of the invention
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 device of 3 detection table tennis net height, the technical scheme taked is, totally be made up of three same detection chis, wherein each detection ruler is formed by with lower component, neodymium iron boron strong magnetic piece embeds in the middle end side surface of right, also the middle end side surface of left can be embedded, connect standpipe above rod support below it to be adsorbed by neodymium iron boron strong magnetic piece, vertical rod lower thread is threaded through nut, riser upper threaded hole realizes connecting, vertical rod upper lateral riveted joint straight pin, screw standpipe to make below its straight pin, to touch online end distance table top 15.25 centimetres, by screw on nut, standpipe and vertical rod are fixed.
Move described rod support to thruster, make its rod support depart from neodymium iron boron strong magnetic piece adsorption range, remove detection ruler.
Compared with these 3 devices detecting table tennis net height are high with existing ruler special ruler survey grid, its beneficial effect is: small in volume cost is low, is convenient for carrying operation and 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 present invention is described in detail.
Fig. 1 is that 3 masters detecting the device of table tennis net height look sketch;
Fig. 2 is that sketch is looked on a left side of Fig. 1;
Fig. 3 is the diagrammatic top view of Fig. 1;
Embodiment
With reference to accompanying drawing, three pieces of neodymium iron boron strong magnetic pieces 1 embed in the middle end side surface 10 of right 8, also the middle end side surface of left 9 can be embedded, rod support 2 connects above standpipe 3 below it and is adsorbed by neodymium iron boron strong magnetic piece, vertical rod 5 lower thread is threaded through nut 4, riser upper threaded hole connects, vertical rod upper lateral riveted joint straight pin 6.
When using this device, by its separately rod support be placed on the table top on neodymium iron boron strong magnetic piece respectively, screw standpipe to make below its straight pin, to touch online end 7 distance table top 15.25 centimetres, standpipe vertical rod is fixed by screw on nut again, rod support is moved to thruster after measuring net height, make its rod support depart from neodymium iron boron strong magnetic piece adsorption range, removed.
Claims (2)
1. one kind 3 are detected the device of table tennis net height, it is characterized in that: be totally made up of three same detection chis, wherein each detection ruler is formed by with lower component, neodymium iron boron strong magnetic piece embeds in the middle end side surface of right, also the middle end side surface of left can be embedded, connect standpipe above rod support below it to be adsorbed by neodymium iron boron strong magnetic piece, vertical rod lower thread is threaded through nut, riser upper threaded hole realizes connecting, vertical rod upper lateral riveted joint straight pin, screw standpipe to make below straight pin, to touch online end and distance table top 15.25 centimetres, by screw on nut, standpipe and vertical rod are fixed.
2. a kind of 3 devices detecting table tennis net height according to claim 1, is characterized in that: pass described rod support, make rod support depart from neodymium iron boron strong magnetic piece adsorption range, remove detection ruler.
