Description

Technical Field

[0001] This utility model relates to the field of balance calibration and testing technology, specifically a balance calibration and testing device. Background Art

[0002] A balance calibration test device is a device used to test and adjust the accuracy of a balance, ensuring the precision and reliability of its measurement results. It is usually performed by manually placing weights on the balance and then calibrating the balance.

[0003] A search of Chinese patent CN222013308U reveals an electronic balance calibration device, comprising an electronic balance body, a base, and a support. A support plate is fixedly connected to the side wall of the support, and a groove is formed on the inner wall of the support plate. A sliding plate is slidably connected to the inner wall of the groove, and a weight driving mechanism is connected to the side wall of the sliding plate. A weight adjustment mechanism is provided on one side of the weight driving mechanism. By configuring the electronic balance body, base, support, support plate, sliding plate, groove, and weight driving mechanism, during calibration, the weight driving mechanism connected to the sliding plate picks up the calibration weight from the weight adjustment mechanism, then slides it along the groove to the top of the electronic balance body to place the calibration weight onto the electronic balance body, thus enabling calibration. This method is simple and convenient. The weight adjustment mechanism can provide calibration weights of different weights, facilitating the weight driving mechanism to pick them up for calibration and improving the quality of calibration.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. During the calibration test of the balance scale, a protective cover is needed to wrap the balance scale to prevent external influences on the sensing platform on the balance scale. However, when the protective cover is wrapped around the balance scale, there are no other supporting facilities for the balance scale, making the balance scale susceptible to collisions and shaking, which in turn affects the accuracy of the calibration test.

[0024] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0025] like Figures 1 to 4As shown, an embodiment of this utility model provides a balance calibration and testing device, including a weighing body 1, an induction platform 2 on the weighing body 1, a load-bearing base 3 on one side of the weighing body 1, a first circular block 4 movably mounted on the load-bearing base 3, a support column 5 fixedly mounted on the first circular block 4, a sleeve 6 fixedly mounted on the top of the support column 5, a movable rod 7 movably mounted on the inner side of the sleeve 6, a semi-circular block 8 fixedly mounted on the end of the movable rod 7, a protective cover 9 fixedly mounted on the semi-circular block 8 and abutting against the weighing body 1, two arc strips 10 symmetrically fixedly mounted on the semi-circular block 8, a support plate 11 fixedly mounted on the ends of the two arc strips 10, a circular shell 12 fixedly mounted on the support plate 11, a second circular block 13 movably mounted on the inner side of the circular shell 12, and the second circular block 1... A long bolt 14 is fixedly installed on the support 3, and a threaded block 15 is fixedly installed on the support 5, with the threaded block 15 threadedly connected to the long bolt 14. Two limiting mechanisms are symmetrically arranged on the support 3. A positioning bolt 16 is threadedly installed on the inner side of the support plate 11. A threaded plate 17 is fixedly installed on the support 3, with the threaded plate 17 threadedly connected to the positioning bolt 16. The limiting mechanism includes a sliding shell 18 fixedly installed on the support 3, with an opening on the sliding shell 18. The limiting mechanism also includes a slider 19 movably installed inside the sliding shell 18, with a limiting plate 20 fixedly installed on the slider 19. The limiting mechanism also includes a screw block 21 fixedly installed on the slider 19, with a fastening nut 22 threadedly installed on the screw block 21, and the fastening nut 22 abutting against the sliding shell 18.

[0026] In this embodiment of the utility model, the operator moves the scale body 1 to one side of the load-bearing seat 3, moves the two limiting plates 20, and causes the limiting plates 20 to drive the slider 19 to move along the inner side of the sliding shell 18 under the action of external force, so that the two limiting plates 20 fit against the two sides of the scale body 1. The operator then tightens the fastening nut 22, causing the fastening nut 22 to move under the thread support of the screw block 21, so that the fastening nut 22 fixes the slider 19 by pressing the sliding shell 18. The scale body 1 is clamped and fixed by adjusting the position of the limiting plates 20. By rotating the support column 5, the support column 5 drives the protective cover 9 to move under the action of external force through the sleeve 6, the movable rod 7 and the semi-circular block 8, so that the protective cover 9 moves to the top of the scale body 1. Finally, the operator tightens the long bolt 14. The long bolt 14, supported by the threaded block 15, moves the protective cover 9 to abut against the scale body 1 via the second round block 13, round shell 12, support plate 11, arc strip 10, and semi-circular block 8. The protective cover 9 then encloses the induction table 2 and the weights. The positioning bolt 16 is then turned, moving into the inner side of the threaded plate 17 under the threaded support of the support plate 11. The positioning bolt 16 fixes the support column 5, thus providing stable support for the scale body 1 and the protective cover 9, thereby increasing the accuracy of the scale body 1 calibration test. By adjusting the limit plate 20 and turning the long bolt 14, scale bodies 1 of different specifications can be stably supported, and the protective cover 9 can be fixed on scale bodies 1 of different specifications, thereby increasing practicality.

[0027] Figures 1 to 4 As shown, two outer shells 23 are fixedly installed on the load-bearing base 3, and a sealing plate 24 is movably installed on the outer shell 23. Multiple weights of different sizes are loaded on the inner side of the outer shell 23.

[0028] In this embodiment of the utility model, the staff seals the weights with the sealing plate 24 and the outer shell 23 to prevent the weights from being exposed to the outside world and corroded, making it convenient for the staff to use the weights.

[0029] Working principle: The operator moves the scale body 1 to one side of the load-bearing seat 3, clamps and fixes the scale body 1 by adjusting the position of the limiting plate 20, opens the sealing plate 24, takes a suitable weight from the inside of the outer shell 23 and places it on the top of the induction table 2, rotates the support column 5, and moves the protective cover 9 through the sleeve 6, movable rod 7 and semi-circular block 8, so that the protective cover 9 moves to the top of the scale body 1. Tighten the long bolt 14, and under the thread support of the threaded block 15, the long bolt 14 moves the protective cover 9 to abut against the scale body 1 through the second circular block 13, circular shell 12, support plate 11, arc strip 10 and semi-circular block 8, so that the protective cover 9 covers the induction table 2 and the weight. The operator then performs calibration and testing on the scale body 1.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
