A connecting ring 4 is integrally formed on the top end of the protective box 2. An external thread is provided on the outer ring surface of the connecting ring 4, and an internal thread is provided on the inner ring surface of the protective cover 5. The external thread and the internal thread are connected in cooperation. A plurality of anti-slip grooves are formed on the outer ring surface of the protective cover 5; a silica gel pressing piece 6 is fixed on the bottom surface of the top plate of the protective cover 5. The silica gel pressing piece 6 is a stepped circular plate. The top plate body of the silica gel pressing piece 6 is clamped between the top plate of the protective cover 5 and the top surface of the standard weight body 1. The middle plate body of the silica gel pressing piece 6 overlaps on the top surface of the silica gel cover 3. The bottom plate of the silica gel pressing piece 6 is inserted into the groove opening of the silica gel cover 3.

[0022] Put the standard weight body 1 into the protective box 2 for storage. The silica gel cover 3 is wrapped under the protective box 2 to prevent the standard weight body 1 from jolting in the protective box 2. After screwing the protective cover 5 onto the connecting ring 4, the silica gel pressing piece 6 is tightly clamped between the protective cover 5 and the standard weight body 1, so as to protect the standard weight body 1 from above and prevent the standard weight body 1 from jolting between the standard weight body 1 and the protective cover 5.

[0023] A reserved groove 7 is formed on the bottom surface of the protective box 2. A transparent cover 8 is fixed on the top surface of the reserved groove 7. An identification paper sheet 9 is inserted between the transparent cover 8 and the reserved groove 7. A rubber sealing piece 10 is fixed at the bottom end of the reserved groove 7. The rubber sealing piece 10 blocks under the transparent cover 8. The reserved groove 7 is an annular groove. A plurality of rubber rings 12 are fixed on the side wall of the reserved groove 7. The plurality of rubber rings 12 are arranged in an equidistant and equal-size manner in the vertical direction. The identification paper sheet 9 is clamped between the transparent cover 8 and the rubber rings 12; the rubber sealing piece 10 is a circular ring plate. The inner ring opening of the rubber sealing piece 10 is sleeved and fixed at the bottom end of the reserved groove 7.

[0024] During use, relevant information of the standard weight body 1 is written on the surface of the identification paper sheet 9. The rubber sealing piece 10 is turned downwards, and then the identification paper sheet 9 is inserted into the transparent cover 8 and the reserved groove 7. At this time, the rubber ring 12 increases the friction between the identification paper sheet 9 and the reserved groove 7 to prevent the identification paper sheet 9 from slipping out of the reserved groove 7. Then, the rubber sealing piece 10 is turned back, and the rubber sealing piece 10 is pushed to make the rubber plug ring 11 inserted into the groove between the reserved groove 7 and the transparent cover 8, realizing anti-detachment shielding for the bottom of the identification paper sheet 9.

[0025] An electronic scale calibration device includes a standard weight.

[0026] The protection process after using the standard weight is as follows:

[0027] 1. Storage and protection of the standard weight:

[0028] Placing the standard weight body into the protection box: The standard weight body 1 is placed inside the protection box 2. The protection box 2 is designed to accommodate the standard weight body 1 and provide preliminary protection.

[0029] The protective function of the silica gel cover: The silica gel cover 3 is sleeved under the standard weight body 1 and clamped between the protection box 2 and the standard weight body 1. The height of the silica gel cover 3 is less than the height of the groove of the protection box 2 to ensure that the silica gel cover 3 can completely wrap the bottom of the standard weight body 1 and prevent it from jolting or being impacted inside the protection box 2.

[0030] Fixing and protection of the protective cover: A connecting ring 4 is integrally formed at the top end of the protection box 2, and an external thread is provided on the outer ring surface of the connecting ring 4. An internal thread is provided on the inner ring surface of the protective cover 5. Through the cooperation of the external thread and the internal thread, the protective cover 5 is screwed and connected to the connecting ring 4. A plurality of anti-slip grooves are formed on the outer ring surface of the protective cover 5 to facilitate the user to screw the protective cover 5. A silica gel pressing piece 6 is fixed to the bottom surface of the top plate of the protective cover 5, and the silica gel pressing piece 6 is designed as a stepped circular plate. The top plate body of the silica gel pressing piece 6 is clamped between the top plate of the protective cover 5 and the top surface of the standard weight body 1 to protect the standard weight body 1 from above. The middle plate body of the silica gel pressing piece 6 overlaps on the top surface of the silica gel cover 3 to further stabilize the position of the standard weight body 1. The bottom plate of the silica gel pressing piece 6 is inserted into the groove of the silica gel cover 3 to ensure that the standard weight body 1 will not move or jolt in the vertical direction.

[0031] 2. Installation and fixation of the identification paper sheet:

[0032] Writing on the identification paper sheet: Relevant information of the standard weight body 1, such as weight, number, etc., is written on the surface of the identification paper sheet 9.

[0033] Inserting the identification paper sheet: The rubber sealing piece 10 is turned downwards to expose the opening of the reserved groove 7. The written identification paper sheet 9 is inserted between the transparent cover 8 and the reserved groove 7.

[0034] Frictional effect of the rubber ring 12: A plurality of rubber rings 12 are fixed to the side wall of the reserved groove 7, and these rubber rings 12 are arranged vertically at equal distances and of equal size. The rubber rings 12 increase the frictional force between the identification paper sheet 9 and the reserved groove 7, preventing the identification paper sheet 9 from slipping out of the reserved groove 7.

[0035] Fixing of the rubber sealing piece and the rubber plug ring: Turn the rubber sealing piece 10 back so that it covers the lower part of the transparent cover 8. Push the rubber sealing piece 10 so that the rubber plug ring 11 (a circular ring plate with a circular arc cross-section) is inserted into the groove between the reserved groove 7 and the transparent cover 8. The insertion of the rubber plug ring 11 further fixes the position of the identification paper sheet 9, preventing it from falling off from the bottom.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
