Description

Technical Field

[0001] This utility model relates to the field of tension and compression sensor technology, specifically a deformation-resistant hyperbolic beam tension and compression sensor. Background Technology

[0002] Pressure sensors, also known as resistance strain gauge sensors, belong to the weighing sensor series. They are devices that convert physical signals into measurable electrical signals. They are widely used in industrial weighing systems, platform scales, electronic scales, crane scales, batching scales, and other force measurement applications.

[0003] For example, the tension and compression sensor calibration device disclosed in the authorization announcement number CN 206583571 U, although it provides a tension and compression sensor calibration device that can calibrate the tension and compression values ​​within the sensor's range, does not solve the problem that in the existing hyperbolic beam tension and compression sensors, the tension and compression components cannot be installed during use, which leads to direct contact with the sensor body during use, which may cause sensor deformation and affect the accuracy of the measured data. Summary of the Invention

[0004] The purpose of this invention is to provide a deformation-resistant hyperbolic beam tension and compression sensor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The deformable body is fixedly disposed at the bottom end of the upper curved beam, and the lower curved beam is fixedly disposed at the bottom end of the deformable body.

[0007] The upper and lower curved beams are equipped with tension and compression assembly mechanisms at both ends. The tension and compression assembly mechanism includes a tension component, a pull plate, a fixing screw, a connecting column, a pull ring, a pressure component, and a pressure screw. The tension and compression assembly mechanism includes a tension component, which includes a pull plate. The pull plate is fixed to both ends of the upper and lower curved beams by fixing screws. A connecting column is provided at the top of the pull plate, and a pull ring is provided at the top of the connecting column. The tension and compression assembly mechanism includes a pressure component, which includes pressure screws at both ends.

[0008] Preferably, a sensor connecting cylinder is provided on one side of the deformed part, and a connecting nut is provided around the circumference of the sensor connecting cylinder. The connecting nut is used to fix the sensor connecting cylinder and the line connecting cylinder together. A connecting wire is fixedly provided inside the line connecting cylinder. The advantage is that the sensor connecting cylinder and the line connecting cylinder can effectively protect the safety of the signal transmission line inside the sensor and effectively prevent it from being corroded by wear, liquids, etc.

[0009] Preferably, a signal transmission line is fixedly installed inside the connecting line. The advantage is that the detected data can be converted into electrical signals by the sensor circuit board and transmitted to the user for observation and recording through the signal transmission line.

[0010] Preferably, the deformable part has a deformation groove inside. The advantage is that the measurement sensitivity of the sensor can be effectively controlled by adjusting the size of the deformation groove during the production process.

[0011] Preferably, a sensor circuit board is provided on one side of the signal transmission line. The advantage is that the pressure signal can be quickly converted into an electrical signal for transmission.

[0012] Preferably, the upper curved beam and the lower curved beam include several fixing screw holes of different sizes. The advantage is that the tension component or pressure component can be quickly and conveniently fixed on the upper curved beam and the lower curved beam through the fixing screw holes, so as to improve the accuracy of the data during testing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This invention relates to a deformation-resistant hyperbolic beam tension and compression sensor. In existing hyperbolic beam tension and compression sensors, the inability to install tension and compression components during use leads to direct contact with the sensor body, which may cause sensor deformation and affect the accuracy of the measured data. Therefore, this deformation-resistant hyperbolic beam tension and compression sensor is proposed. By setting tension and compression components, direct contact with the sensor body can be prevented without affecting the accuracy of the measured data, effectively improving the service life of the pressure sensor.

The tension and compression assembly mechanism includes a tension component 4, a pull plate 5, a fixing screw 6, a connecting column 7, a pull ring 8, a pressure component 9, and a pressure screw 10. The tension and compression assembly mechanism includes a tension component 4, which includes a pull plate 5.

[0025] In this embodiment, preferably, a sensor connecting cylinder 11 is provided on one side of the deformed shape 2, and a connecting nut 12 is provided around the sensor connecting cylinder 11. The sensor connecting cylinder 11 and the line connecting cylinder 13 are fixed together by the connecting nut 12. A connecting wire 14 is fixedly provided inside the line connecting cylinder 13. The sensor connecting cylinder 11 and the line connecting cylinder 13 can effectively protect the safety of the signal transmission line 15 inside the sensor and effectively prevent it from being corroded by wear, liquid, etc.

[0026] In this embodiment, preferably, a signal transmission line 15 is fixedly installed inside the connecting line 14. The sensor circuit board 17 can convert the detected data into an electrical signal and transmit it to the user for observation and recording through the signal transmission line 15.

[0027] In this embodiment, preferably, the deformable body 2 is provided with a deformation groove 16. By adjusting the size of the deformation groove 16 during the production process, the measurement sensitivity of the sensor can be effectively controlled.

[0028] In this embodiment, preferably, a sensor circuit board 17 is provided on one side of the signal transmission line 15, which can quickly convert the pressure signal into an electrical signal for transmission.

[0029] In this embodiment, preferably, the upper curved beam 1 and the lower curved beam 3 include several fixing screw holes 18 of different sizes. The tension component 4 or the pressure component 9 can be quickly and conveniently fixed on the upper curved beam 1 and the lower curved beam 3 through the fixing screw holes 18, so as to improve the accuracy of the data when testing.

[0030] In this embodiment of the anti-deformation hyperboloid tension / compression sensor, in use, in Embodiment 1: During use, the pull plate 5 is fixed to both ends of the upper curved beam 1 and the lower curved beam 3 by fixing screws 6. Then, through the connecting column 7 and the pull ring 8, the upper curved beam 1, the lower curved beam 3, and the deformable body 2 are driven. During this process, the sensor circuit board 17 inside the deformable body 2 will convert the detected data into an electrical signal through the signal transmission line 15 and transmit it to the user for observation and recording. In Embodiment 2: During use, the pressure screw 10 is installed at both ends of the upper curved beam 1 and the lower curved beam 3. Then, the pressure screw 10 is used to press the upper curved beam 1 and the lower curved beam 3. During this process, the sensor circuit board 17 inside the deformable body 2 will transmit the detected data through the signal transmission line 15. The detected data is converted into electrical signals and transmitted to the user for observation and recording via signal transmission line 15. The advantage lies in the fact that existing hyperbolic beam tension and compression sensors cannot install tension and compression components during use, leading to direct contact with the sensor body and potentially causing sensor deformation, thus affecting the accuracy of the measured data. Therefore, a deformation-resistant hyperbolic beam tension and compression sensor is proposed. By setting tension component 4 and compression component 9, direct contact with the sensor body can be prevented without affecting the accuracy of the measured data, effectively improving the service life of the pressure sensor. Furthermore, the sensor connecting cylinder 11 and the line connecting cylinder 13 effectively protect the safety of the internal signal transmission line 15 of the sensor, effectively preventing it from being corroded by wear, liquids, etc.
