The fourth cylinder 16 can drive the toggle plate 17 to move up and down.

[0024] The barrel cover 2 can cover the top wall of the transparent barrel 1 , and the barrel cover 2 completely covers the inner cavity of the transparent barrel 1 . The barrel cover 2 is located on the inner side of the annular sliding block 8 .

[0025] In this embodiment, the inner side of the carrying plate 10 and the moving plate 13 is the side close to the axis of the transparent barrel 1.

[0026] In this embodiment, the annular sliding block 8 is connected to the first annular groove in a sliding and sealing manner.

[0027] In this embodiment, a first battery is disposed on the carrier plate 10 , and the first battery supplies power to the first cylinder 11 , the second cylinder 12 , the third cylinder 15 and the fourth cylinder 16 .

[0028] In this embodiment, a limiting groove 6 is provided on the top wall of the supporting column 5 .

[0029] For miniature square weights, due to their structure or size limitations, they cannot form a weight string. During the verification process, this type of weight cannot be added in sequence, and can only be verified manually one by one, resulting in extremely low efficiency of miniature square weights during loading and verification. The verification accuracy of miniature weights is high. The current verification directly places the miniature weights on the comparator 3. The breathing and movement of the staff, the airflow generated, and the natural wind in the air will also affect the detection accuracy, resulting in insufficient verification accuracy for tiny weights.

[0030] In this embodiment, through the cooperation of the transparent barrel 1, the barrel cover 2, the comparator 3, the support column 4 and the relevant components on the carrying plate 10, a first annular groove is provided on the top wall of the transparent barrel 1, an annular slider 8 is slidably arranged on the first annular groove, and a second annular groove 9 is provided on the inner circumferential wall of the transparent barrel 1, a sliding block is slidably arranged in the second annular groove 9, and the sliding block is connected to the annular slider 8, so that the annular slider 8 is externally moved to drive the sliding block to make a circular motion in the transparent barrel 1, the carrying plate 10 is connected to the sliding block, and the first cylinder 11, the second cylinder 12, the third cylinder 15, the fourth cylinder 16 and the first battery are arranged on the carrying plate 10, and the first battery is the first cylinder 11, the second cylinder 12, the third cylinder 15 and the fourth cylinder 16. The cylinder 16 is powered, and these components can be driven to move as long as the annular slider 8 is moved. At the same time, it is only necessary to set the control buttons of the first cylinder 11, the second cylinder 12, the third cylinder 15 and the fourth cylinder 16 on the top of the annular slider 8, and set a wire channel in the annular slider 8 and the sliding block. The wires for controlling the first cylinder 11, the second cylinder 12, the third cylinder 15 and the fourth cylinder 16 are connected to the control button at one end of the wire channel, and connected to the first cylinder 11, the second cylinder 12, the third cylinder 15 and the fourth cylinder 16 at the other end, so that the movement of the first cylinder 11, the second cylinder 12, the third cylinder 15 and the fourth cylinder 16 can be controlled from the outside without causing disorder in the wire lines;

[0031] The moving plate 13 is connected to the output shaft of the second cylinder 12, and two placing columns 14 are provided on the moving plate 13. A plurality of arc grooves 18 are provided on the placing columns 14. When in use, a plurality of square weights are first hung on the plurality of arc grooves 18, and then the barrel cover 2 covers the inner cavity of the transparent barrel 1 to form a closed space. When adding square weights to the bearing column 5, the moving plate 13 is first moved inward, and the placing column 14 also moves inward. The height of the bearing column 5 is located between the top wall and the bottom wall of the square weight hanging hole. At this time, the inner end of the placing column 14 is located directly above the limiting groove 6. At this time Then, the third cylinder 15 and the fourth cylinder 16 cooperate to drive the toggle plate 17 to move until the inner wall of the toggle plate 17 contacts the outer wall of the outermost square weight. At this time, the toggle plate 17 moves inward to push the square weight to move inward, and the bearing column 5 passes through the hanging hole of the square weight until the square weight falls on the bearing column 5, thereby realizing the addition of the square weight on the bearing column 5. After the weights on each bearing column 5 are added, the moving plate 13 moves to the corresponding position, and the above operation is repeated to realize the addition of the square weight. After the calibration is completed, the barrel cover 2 is opened and the square weight is removed.

[0032] In this way, multiple square weights can be added in sequence in a sealed environment to prevent external airflow from affecting the detection accuracy. At the same time, square weights can be continuously added in a closed ring without adding a barrel cover 2 that is opened once, thereby improving the verification accuracy and verification efficiency of the square weights.

[0033] Embodiment 2:

[0034] This embodiment is further limited on the basis of Embodiment 1. In this embodiment, the top wall of the support column 4 is provided with a receiving hole 19. The barrel cover 2 includes a top plate and a top tube. The top tube is connected to the bottom wall of the top plate. The top tube can be placed on the top wall of the transparent barrel 1. A discharge pipe 20 is fixed in the top tube 1. The discharge pipe 20 is coaxially arranged with the receiving hole 19. A placement box 21 is fixed in the top tube. The top and right ends of the placement box 21 are open. A fifth cylinder 22 is provided on the inner left wall of the placement box 21. A push plate 25 is connected to the output shaft of the fifth cylinder 22. The push plate 25 can push the weight placed in the placement box 21 into the discharge pipe 20 and enter the receiving hole 19 through the discharge pipe 20.

[0035] The bottom wall of the top plate in this embodiment is provided with a sixth cylinder 23, and a blocking plate 24 is connected to the output shaft of the sixth cylinder 23. The sixth cylinder 23 can drive the blocking plate 24 to move up and down, and the blocking plate 24 closes the right end of the placement box 21. The accommodating hole 19 in this embodiment is divided into an upper section and a lower section, and the bottom end of the upper section is connected to the lower section. From the top to the bottom, the diameter of the upper section gradually decreases. The top wall of the transparent barrel 1 in this embodiment is provided with a plurality of positioning holes, and the bottom wall of the top tube is provided with positioning columns, which can enter the positioning holes, and the positioning columns correspond to the positioning holes one by one.

[0036] For miniature cylindrical weights without hanging holes, the current calibration is that the staff places the miniature cylindrical weights on the comparator 3 and calibrates them one by one, which has low calibration efficiency. At the same time, the airflow generated by the staff's breathing and movement, as well as the natural wind in the air, will also affect the calibration accuracy, resulting in insufficient calibration accuracy for the miniature cylindrical weights.

[0037] In this embodiment, a receiving hole 19 is opened on the bottom wall of the support column 4, and the barrel cover 2 includes a top plate and a top cylinder. A discharge pipe 20 and a placement box 21 are arranged in the top cylinder. The miniature cylindrical weights are placed in a row in the placement box 21. When adding, the output shaft of the sixth cylinder 23 moves upward to drive the blocking plate 24 to move upward to open the right end of the placement box 21, and then the fifth cylinder 22 starts to drive the push plate 25 to move to push the weight into the discharge pipe 20, and enter the receiving hole 19 through the discharge pipe 20 to achieve the addition of the miniature cylindrical weight. By controlling the movement of the fifth cylinder 22, one miniature cylindrical weight is added at a time. In this way, the miniature square weights with hanging holes and the miniature cylindrical weights can be calibrated at the same time, thereby improving the calibration efficiency and calibration accuracy of the miniature weights. After the calibration is completed, the support column 4 is taken out and the miniature cylindrical weights can be poured out from the accommodating hole 19.

[0038] In this embodiment, the control buttons of the fifth cylinder 22 and the sixth cylinder 23 are arranged on the top wall of the top plate, and a second battery is arranged on the top plate to supply power to the fifth cylinder 22 and the sixth cylinder 23 .

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
