Detailed Description

The embodiments are further described below in conjunction with the appended drawings:

the grid ruler is used in combination with another special tool, namely a grid spraying tank, so that efficient and accurate grid drawing can be realized, and pigment can be saved. Fig. 1-4 are grid ruler parts, fig. 5-11 are grid spraying tank parts with replaceable spray heads, and fig. 12 is a schematic diagram of a grid drawing method.

Grid ruler

The grid ruler is realized by the following modes: a grid ruler is constructed, and comprises a measuring section 1, a hole site array 2, a left side connector 3, a connecting hole 4, a right side connector 5, a main body plate 6 and a special pin 7.

The measuring section 1 is positioned on the main body plate 6 and is from 0 scale to 17cm from left to right, the scale mark at each whole centimeter is longest, and the length of the scale mark at each 5mm scale is second, so that the starting point and the end point of the grid to be drawn can be observed and measured conveniently. The left side connector 3 is a plug board fixed on the left side, the right side connector 5 is a groove body arranged on the right side, and the plug board and the groove body are mutually meshed and used for combined connection. The hole site array 2 on the main part board 6 has 7 lines and 16 rows, the length of each hole is 7mm, the width is 2mm, the width is equal to the width of a common marking pen, the line spacing is 3mm, the row spacing is 8mm, most scientific research needs are met, and 112 hole sites are arranged for spraying. The special pin 7 is inserted into the combined connecting hole to play a role in fixing. This embodiment employs this type of connection by pins. In practical application, various connection modes can be adopted, as long as the two grid rulers can be detachably connected.

The using method comprises the steps of firstly measuring the length of a grid to be drawn by using the measuring section 1, marking, aligning a grid ruler with the measuring section 1 if the length is short, and spraying the hole site array 2 by using special spraying equipment in alignment along the length direction of the grid ruler. If length overlength needs a plurality of net chi assembly to use, and net chi lower left corner 3 and lower right corner 4 have two connectors, if need draw the vertical section, in order to prevent that the net chi from droing, need fix it with pin 7. The left connector 3 and the right connector 4 are respectively positioned below the main body plate 6 and used for connecting when the length of the measured object exceeds a single grid ruler. The number of the grid ruler connections is not limited, and can be any number, when the grid ruler connections are performed, the left connector 3 needs to be inserted into the right connector 4, and the pins 7 are inserted for fixing according to needs. And finally, spraying the hole site array 2 on the grid ruler by using a special grid spraying tank with a replaceable nozzle, and uniformly spraying right from 0 scale.

Because 90% of the area of the grid ruler is solid, less than 10% of the grid needs to be sprayed, so a special grid spray can with a replaceable spray head is required. The grid spraying tank is attached with a replacing pressure spray head which can accurately correspond to the grid on the grid ruler. Compared with the grid spraying tank without the replacing pressure nozzle, the grid spraying tank with the replacing nozzle can save more than 90% of spraying material, greatly accelerate the grid drawing speed, and shorten the original work of several days to several minutes by matching with the grid ruler.
