Description

Technical Field

[0001] This utility model relates to the field of electronic weighing instrument technology, specifically to a concealed and expandable electronic weighing instrument for measurement. Background Technology

[0002] Electronic weighing instruments are widely used in factories, mines, ports, warehouses, docks, and other industries for weighing and measuring various materials. Electronic weighing instruments include electronic truck scales, electronic rail scales, quantitative packaging scales, steel scales, etc., and generally consist of several parts such as the scale body, load cells, weighing display instruments, mechanical force transmission and limit mechanisms.

[0003] A concealed and expandable electronic weighing instrument disclosed in publication number CN215811197U includes an electronic weighing instrument body. The body has symmetrically connected side support tubes on its left and right sides. A U-shaped frame is fixedly connected to the left side of the bottom inner surface of each side support tube, and a slide rail plate is fixedly connected to the right side of the bottom inner surface of each side support tube. This concealed and expandable electronic weighing instrument allows two upper push plates to move to the left and right, contacting two second lifting frames. Simultaneously, the two second lifting frames move upwards within two slide grooves, contacting the steel material. After the steel material is weighed and removed, two spring assemblies reset the two first lifting frames using their own elasticity. Simultaneously, two L-shaped push rods reset, driving two push plates to reset, and the two second lifting frames reset as well. This eliminates the need for manual intervention, greatly improving the automation of the device.

[0004] However, weighing items of different materials for extended periods can easily cause wear and tear on electronic scales. This wear and tear over time will affect the accuracy of the weighing, and disassembling the weighing components after wear and tear has occurred is troublesome. Utility Model Content

When snapped into the inside of the snap-fit ​​frame 51, the weighing plate 6 will press against the snap-fit ​​block 54. After the snap-fit ​​block 54 is pressed, it will press against the spring 53 on the telescopic rod 52. After the weighing plate 6 moves downward to the appropriate position, the spring 53 on the telescopic rod 52 will drive the snap-fit ​​block 54 to reset, and the snap-fit ​​block 54 will snap into the inside of the weighing plate 6. When weighing steel of different lengths, personnel can pull the extension plate 7 to both sides through the weighing plate 6. After pulling it to the appropriate position, personnel will position the extension plate 7 through the snap-fit ​​rod 10 on the mounting plate 9. After positioning the extension plate 7, the steel is placed on the weighing plate 6. Then, the threaded rod 83 is rotated through the positioning ring 82 on the support plate 81. When the threaded rod 83 rotates, it will drive the clamping plate 84 to move downward. When the clamping plate 84 moves downward, it will fix the steel on the weighing plate 6.
