Technical Field

[0001] The utility model relates to the technical field of electronic scale verification, in particular to an electronic scale verification and calibration test bench. Background Technique

[0002] With the development of social economy and the increasing frequency of economic and trade activities, people have put forward higher requirements for the accuracy and reliability of weighing measurement tools. The popularity rate of electronic scales in commercial activities is very high, and the technical requirements for electronic scales are also getting higher and higher, requiring high accuracy and fast operation speed. In order to ensure the accuracy of electronic scales, it is necessary to frequently verify the electronic scales to ensure the accuracy of their measurement.

[0003] At present, the verification and calibration of electronic scales are mainly carried out by standard weights to verify and calibrate load points such as no-load, minimum weighing capacity, and maximum weighing capacity. Therefore, various specifications of weights are required to support the entire verification and calibration process, which requires staff to frequently replace the weights. After long-term use, the weights will inevitably wear and cause deviation in the weight of the weights, which will undoubtedly affect the accuracy of verification and calibration. Therefore, corresponding improvements need to be made according to the above problems. Content of the Utility Model

Installation holes are opened at positions near both sides inside the supporting board, and the bottom inner walls of the installation holes are fixedly adsorbed and arranged with the bottom ends of magnet rods. The top ends of the magnet rods are installed with the bottom ends of installation plates, and one sides of the installation plates are installed with one sides of U-shaped blocks. Threaded grooves are opened inside the U-shaped blocks, and screw rods are movably screwed inside the threaded grooves. One end of the screw rod is installed with a connecting rod, and one end of the connecting rod is installed with an installation sleeve.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] according to Figures 1-3 As shown, it includes a test bench 1, a mounting column 11 is installed on the top of the test bench 1, and a supporting plate 12 is installed on the outer surface of the mounting column 11. The supporting plate 12 is in a circular shape, and mounting holes 13 are opened on both sides of the inside of the supporting plate 12, and the bottom inner walls of the mounting holes 13 are adsorbed and fixed to the bottom end of the magnet rod 22.

[0021] The top of the magnet rod 22 is installed with the bottom of the mounting plate 21, and one side of the mounting plate 21 is installed with one side of the 匚-shaped block 2. The distance between the inner walls on both sides of the 匚-shaped block 2 is adapted to the width of the mounting column 11. The bottom end of the 匚-shaped block 2 and the bottom ends of the two groups of mounting plates 21 are fitted with the top of the supporting plate 12. A threaded groove 23 is provided inside the 匚-shaped block 2, and a screw 24 is movably screwed inside the threaded groove 23. A connecting rod 25 is installed at one end of the screw 24, and a mounting sleeve 26 is installed at one end of the connecting rod 25. Four groups of positioning holes 27 are provided inside the mounting sleeve 26, and the four groups of positioning holes 27 are centrally symmetrically arranged with the center point of the mounting sleeve 26 as the center point.

[0022] An electric push rod 3 is movably arranged inside the mounting sleeve 26, and a pressure plate 33 is installed at the bottom end of the electric push rod 3. The outer diameter of the pressure plate 33 is matched with the inner diameter of the mounting sleeve 26, so that the pressure plate 33 can move freely up and down inside the mounting sleeve 26. A mounting plate 31 is installed on the side surface of the electric push rod 3, and four groups of positioning rods 32 are installed at the bottom end of the mounting plate 31. The positioning rods 32 pass through the interior of the mounting sleeve 26 through the positioning holes 27.
