[0001] The utility model relates to the technical field of measuring instrument detection, in particular to a detection device for measuring instruments. Background Technique

[0002] A tensiometer is an instrument used to measure the magnitude of force, mainly used to determine mechanical properties such as the tensile strength, breaking force, and elastic modulus of materials. Tensiometers are applied in various occasions such as laboratories, factories, and construction sites.

[0003] Accuracy and reliability are crucial for ensuring the accuracy of various measurement results. Therefore, tensiometers need to be calibrated regularly to ensure that their performance meets the standard requirements. The existing detection method is to fix the tensiometer and use weights for detection and calibration. It is rather troublesome to install and fix the tensiometer, and it is also rather troublesome to add and replace weights each time. Especially when continuously detecting a large number of tensiometers, manual operation is time-consuming and laborious. Content of the Utility Model

[0021] As Figures 1 to 3 shown, the technical solution adopted by the present invention is as follows: A detection device for a measuring instrument, including a detection base 1, a support frame 2 and an installation detection structure 3. The support frame 2 is arranged in a C-shaped structure, the support frame 2 is installed on the detection base 1, and the installation detection structure 3 is installed on the support frame 2. The installation detection structure 3 includes an electric telescopic rod 4, a lifting installation plate 5, a pressing vertical plate 6 and a tensile meter body 7. Guide chutes 8 are provided on the opposite side walls inside the support frame 2, and both ends of the lifting installation plate 5 are slidably arranged in the guide chutes 8. A positioning groove 9 is provided at the top of the lifting installation plate 5. There are two groups of pressing vertical plates 6, and the two groups of pressing vertical plates 6 are vertically arranged on both sides of the positioning groove 9 of the lifting installation plate 5. A connecting cross plate 10 is provided at the top of the two groups of pressing vertical plates 6. The electric telescopic rod 4 is installed at the top of the support frame 2 and its free end is connected to the connecting cross plate 10. The tensile meter body 7 is placed in the positioning groove 9 and its tensile test end extends downward through the positioning groove 9. In order to further increase the installation stability of the tensile meter body 7, a tightening screw 18 is penetrated through the pressing vertical plate 6 and connected by threads. Anti-slip rubber pads 19 and adjusting knobs 20 are respectively provided at both ends of the tightening screw 18.

[0022] As Figure 1 and Figure 2As shown in the figure, in order to facilitate the continuous connection of different weight weights to the dynamometer body 7, a weight installation structure is also provided on the detection base 1. The weight installation structure includes a turntable 11, a weight installation box 12 and a driving motor 13. The turntable 11 is rotatably arranged on the detection base 1. An installation cavity is provided in the detection base 1. The driving motor 13 is arranged in the installation cavity and the power output shaft is connected to the turntable 11. An installation concave platform is provided on the turntable 11. An electromagnet 14 is provided on the bottom wall of the installation concave platform. The weight installation box 12 is slidably arranged in the installation concave platform. The electromagnet 14 is connected and fixed to the weight installation box 12 and extracted for detection by energizing and de-energizing the electromagnet 14;

[0023] As Figure 3 shown, a weight placement cavity 15 is provided in the weight installation box 12. A first magnet 16 is provided on the top of the weight installation box 12. A second magnet 17 is installed at the detection end of the dynamometer body 7. The first magnet 16 and the second magnet 17 are set with different magnetic polarities. The magnetic attraction between the first magnet 16 and the second magnet 17 is less than the suction force of the electromagnet 14 on the weight installation box 12, which facilitates the separation of the first magnet 16 and the second magnet 17 when replacing the weight installation box 12. Multiple groups of weight installation boxes 12 are evenly distributed around the central axis of the turntable 11, and multiple groups of different weights can be calibrated one by one to achieve continuous detection.

Rotate the pressing screw 18 to further press both sides of the dynamometer body 7 through the anti-slip rubber pad 19. Then start the electric telescopic rod 4 to drive the lifting installation plate 5 and the dynamometer body 7 to move downward. Connect the weight installation box 12 through the attraction of the first magnet 16 and the second magnet 17, disconnect the electromagnet 14, and retract the free end of the electric telescopic rod 4 to detect the total weight of the weight installation box 12. After the detection is completed, put the weight installation box 12 back, turn on the electromagnet 14. The magnetic attraction between the first magnet 16 and the second magnet 17 is less than the suction force of the electromagnet 14 on the weight installation box 12, so that the first magnet 16 and the second magnet 17 are separated. Drive the turntable 11 to rotate through the driving motor 13, and then calibrate the next group of weight installation boxes 12.
