[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a calibration device for weighing and metrological verification includes a first weight 1 composed of a first weight cylinder column 101 and a first outer ring edge 102. The inner side of the first weight cylinder column 101 is of a cavity structure. The first outer ring edge 102 is fixed to the outer side of the top of the first weight cylinder column 101. A combined weight 2 is placed inside the first weight cylinder column 101. The combined weight 2 includes a second weight cylinder column 201 and a second outer ring edge 202. The second weight cylinder column 201 is placed inside the first weight cylinder column 101. The second outer ring edge 202 is fixed to the outer side of the top of the second weight cylinder column 201 and fits on the upper surface of the first outer ring edge 102. The heaviest weight is formed by combining multiple combined weights 2 with the first weight 1. The weight of the weight is changed by sequentially removing one combined weight 2;

[0024] A quick installation component 3 is provided between the first weight 1 and the combined weight 2. The quick installation component 3 is used to achieve the convenient disassembly and assembly of the first weight 1 and the combined weight 2;

[0025] The quick installation component 3 includes a fixed column 301, a sector-shaped clamping block 302, a semi-circular docking groove 303, a central circular groove 304, and a semi-circular clamping groove 305;

[0026] The fixed column 301 is fixed to the middle of the bottom end of the inner cavity of the first weight cylinder column 101, and the sector-shaped clamping block 302 is fixed to one side of the top of the fixed column 301;

[0027] The semi-circular docking groove 303 is opened at the bottom of the second weight cylinder column 201. The semi-circular card slot 305 is opened at one side of the top inner wall of the semi-circular docking groove 303. The central circular groove 304 is opened at the center of the bottom of the second weight cylinder column 201 and is communicated with the semi-circular docking groove 303 and the semi-circular card slot 305. The semi-circular docking groove 303 and the semi-circular card slot 305 are circumferentially distributed with the central circular groove 304 as the center;

[0028] The second weight cylinder column 201 is sleeved outside the fixed column 301 and the sector-shaped card block 302 through the semi-circular docking groove 303 and the central circular groove 304. By rotating the second weight cylinder column 201 by 180 degrees, the sector-shaped card block 302 is clamped with the semi-circular card slot 305 to realize the connection between the second weight cylinder column 201 and the first weight cylinder column 101;

[0029] The number of the combined weights 2 is set to be multiple. The multiple second weight cylinder columns 201 in the multiple combined weights 2 are sequentially sleeved, and the multiple second weight cylinder columns 201 are connected by the quick assembly component 3.

[0030] In this embodiment: When performing weighing and metrological verification with this weight, multiple combined weights 2 and the first weight 1 can be sequentially sleeved and assembled to form a heaviest weight. At this time, this heaviest weight can be placed as a whole on the weighing scale to be detected, and thus the first detection can be carried out. After that, the second weight cylinder column 201 at the top can be rotated by 180 degrees to make the semi-circular docking groove 303 on this second weight cylinder column 201 rotate to be aligned with the lower sector-shaped card block 302. At this time, the connection between the two second weight cylinder columns 201 is released. After that, the second weight cylinder column 201 at the top can be taken away, and thus the second detection can be carried out. By repeating this process, multiple detection operations can be completed. Compared with the traditional operation of first taking away the heavier weight and then putting in the lighter weight for repeated detection, the overall operation is more convenient and can effectively improve the detection efficiency;

[0031] It should be additionally noted that: When initially placing the weight, the corresponding number of combined weights 2 and the first weight 1 can be selected according to the weighing range of the weighing scale to be detected to avoid overweight of the initially placed weight. Additionally, when performing repeated detection, one or more combined weights 2 can be taken away synchronously according to the detection needs, and the overall detection is more flexible;

[0032] In addition, it should be noted that: The weights of the multiple combined weights 2 and the first weight 1 can be set evenly or gradually decreasing.

[0033] Please refer specifically to Figures 1 to 5 , notches 4 are opened on both the second outer ring edge 202 and the first outer ring edge 102 in the multiple combined weights 2. The notches 4 and the sector-shaped card blocks 302 are distributed on the same side of the fixed column 301 with the fixed column 301 as the center.

[0034] In this embodiment: Through the notch groove 4, the relative positional relationship of the sector-shaped clamping block 302, the semi-circular docking groove 303, and the semi-circular clamping groove 305 can be quickly judged, so that the connection and disassembly between the multiple combined weights 2 and the first weight 1 can be better completed;

[0035] In addition, the size of the notch groove 4 can be set according to the parts of the quick-installation component 3 on the combined weight 2 and the first weight 1, so as to offset the weight eccentricity caused by the parts of the quick-installation component 3 to the combined weight 2 and the first weight 1, and keep the centers of the combined weight 2 and the first weight 1 in a centered state.

[0036] Please refer specifically to Figures 1 to 4 , the outer diameters of the multiple second outer ring edges 202 in the multiple combined weights 2 increase sequentially from top to bottom, and the outer diameter of the bottommost second outer ring edge 202 is smaller than the outer diameter of the first outer ring edge 102.

[0037] In this embodiment: Through this structure, it is convenient for the operator to synchronously remove one or more combined weights 2.

[0038] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
