[0020] See also Figure 1-4 , the utility model provides a technical solution:

[0021] A tool for measuring the central curvature of a tile comprises a ruler 1, a fixing device 2, and a moving device 3. The fixing devices 2 are fixedly connected to both sides of the ruler 1. The fixing devices 2 comprise a first stretching plate 201, a second stretching plate 202, a vertical plate 206, and a horizontal plate 207. An inner cavity is provided inside the first stretching plate 201. Second sliders 205 are provided on both sides of the inner cavity. The second stretching plate 202 is located inside the inner cavity. Second slide grooves 204 are provided on both sides of the second stretching plate 202. The second slide grooves 204 are snap-fittedly connected to the second sliders 205. Vertical plates 206 are provided at both outer ends of the top of the first stretching plate 201. A horizontal plate 207 is provided on the top of the vertical plate 206. A circular hole is provided at the center of the horizontal plate 207. A threaded rod 208 is threadedly connected to the inside of the circular hole. A pressing block 210 is provided at the bottom of the threaded rod 208. A knob 209 is provided at the top of the threaded rod 208.

[0022] The front and rear ends of the ruler 1 are provided with first slide grooves 103, and the two ends of the first slide groove 103 are provided with moving devices 3, which include a bottom plate 301, a connecting plate 302, and a first slider 303. The first slider 303 is slidably connected to the first slide groove 103, and the outer sides of the two first slide grooves 103 are provided with connecting plates 302. The bottoms of the two connecting plates 302 are connected to the two ends of the top of the bottom plate 301, and the tops of the two connecting plates 302 are provided with supporting plates 304. The top center of the supporting plate 304 is provided with a fixing hole 305, and the bottom of the bottom plate 301 is provided with a screw micrometer 306;

[0023] A central through hole 101 is provided at the center of the top of the ruler 1 , a rivet 5 is provided inside the central through hole 101 , a triangle mark 6 is provided on the outer surface of the rivet 5 , and a level bubble 4 is provided at the top of the ruler 1 and outside the rivet 5 .

[0024] Furthermore, a clamping plate 203 is disposed on the outer side of the second stretching plate 202, and the bottom of the clamping plate 203 is located below the top surface of the tile.

[0025] Furthermore, a plurality of limiting holes 102 are provided on both sides of the two ends of the ruler 1, and the fixing holes 305 located at different corners are connected to one of the fixing holes 102 therein through a plug-in pin.

[0026] Working principle: Before using the purchased tiles, the tiles need to be measured. First, fix the fixing device 2 in the utility model to both sides of the tiles. The second stretching plate 202 can be pulled out appropriately according to the length of the tiles. Then, the clamping plate 203 at the outer end of the second stretching plate 202 is engaged with the side of the tiles. Then, the threaded rod 208 is rotated by the knob 209, and the threaded rod 208 will move downward, so that the pressing block 210 will press the first stretching plate 201, thereby fixing the utility model.

[0027] After the fixation is completed, the ceramic tile can be measured by the utility model. During the measurement, the staff moves the moving device 3. During the movement of the moving device 3, the first slider 303 will slide at the first slide groove 103. During the sliding process, the micrometer 306 will measure the distance between the ceramic tiles. The level bubble 4 is leveled by the micrometers 306 on both sides. The distance difference between the two micrometers 306 is called ΔC, and the center curvature is then obtained. Next to the level bubble 4 is a rivet that can fall freely, on which a triangle mark 6 is engraved. When the triangle mark 6 is fully exposed, it proves that the ruler 1 is level with the ceramic tile and there is no error in ΔC. When the triangle mark 6 is not fully exposed, the micrometers 306 on both sides still need to be adjusted.

[0028] Specifically, when the triangle mark 6 is completely exposed, the fixing hole 305 can be fixed to the limiting hole 102 by means of an insertion pin, so that the distance can be better measured, thereby reducing the error of the measurement result.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
