[0020] The utility model will be further described below in combination with the drawings and implementation.

[0021] Please combine with reference to Figures 1 to 5 A novel glass edging size measuring instrument zero plate 1, the core component is zero plate body 11. On one side edge of zero plate body 11, connecting convex part 12 is set symmetrically, these connecting convex parts 12 are integrally formed with zero plate body 11, ensure the stability of structure. The top of connecting convex part 12 is symmetrically equipped with positioning column 13, these positioning columns 13 as zero positioning reference, can effectively avoid the measurement error caused by improper zero, thereby improving the accuracy of measurement.

[0022] Through actual test comparison, we can clearly see the advantage of this novel zero plate. When using traditional zero plate to carry out continuous three times zero, with the first zero as the reference and set to 0 value, the result of the second zero is 0.04, and the result of the third zero is-0.03, showing that there is a big difference in zero result. However, when we use this novel zero plate to carry out the same test, the zero results of the second and third times are both 0 value, which is completely consistent with the first zero, without any difference, fully proving the stability and reliability of the novel zero plate.

[0023] The bottom of positioning column 13 is provided with threaded connection part 17, zero plate body 11 is provided with threaded groove 18 engaged with threaded connection part 17, the top of positioning column 13 is provided with screwdriver slot 19 matched with screwdriver, positioning column 13 is screwed by screwdriver inserted into screwdriver slot 19, convenient to install and fix positioning column 13.

[0024] In addition, the semicircular notches 15 are symmetrically designed in the middle positions of the two side edges of the zero calibration plate body 11. These semicircular notches 15 not only facilitate the user to easily pick up the zero calibration plate body 11 with fingers, but also make the hand feel more comfortable due to the arc design, effectively preventing the situation that the worker may be scratched in the use process.

[0025] At the same time, the intersection of the semicircular notches 15 and the side edges of the zero calibration plate body 11 also adopts a circular arc transition design, further improving the comfort and safety of use. In addition, a plurality of circular holes 16 are also ingeniously arranged on the zero calibration plate body 11. These circular holes 16 not only save materials and reduce the weight of the zero calibration plate, but also facilitate the user to pick up and move the zero calibration plate.

[0026] The depth of the threaded groove 18 is less than the thickness of the zero calibration plate body 11, reducing the risk of rusting of the threaded groove 19.

[0027] The four corners of the zero calibration plate body 11 are provided with a second rounded corner, improving the comfort and safety of use.

[0028] Finally, the edge of the circular hole 16 is also carefully designed with a first rounded corner, which is also designed to improve the comfort and safety of use and prevent any harm to the worker in the use process. In general, the new type of glass edging size measuring instrument zero calibration plate 1 has shown excellent performance and advantages in design and practicability.

[0029] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion, or direct or indirect application in other related technical fields, which is based on the content of the present application specification and drawings, is also included in the patent protection range of the present application.
