Problems solved by technology
[0003] In the prior art, a through hole is opened in the cavity of the pressure calibration mechanism, through which electronic products such as drones are connected to the data receiving device. However, when performing pressure calibration, the through hole opened in the cavity of the pressure calibration mechanism Hole sealing is a significant risk for this test
In the prior art, glue is usually used to seal the through hole, and the sealing effect achieved by sealing it in this way is poor. In addition, sealing it in this way requires the tester to continuously replenish the glue work, making the operation steps complicated

The invention discloses a pressure calibration device, which comprises a pressing module, a profiling module and a communication line switching module. The profiling module is used for placing a device for being subjected to pressure calibration. The pressing module and the profiling module are in press fit with each other so as to calibrate the pressure of the device for being subjected to pressure calibration. The profiling module is provided with a through hole. The communication line switching module is assembled in the through hole and is used for switching and delivering the pressure calibration data of the device for being subjected to pressure calibration during the pressure calibration process. The communication line switching module comprises a communication line switching part. The two ends of the communication line switching part is provided with communication line interfaces in a direction parallel to the axial direction of the through hole in the profiling module. The communication line interfaces at the two ends of the communication line switching part are mutually in communication connection. By the pressure calibration device provided in the invention, the airtightness of the connection part of the receiving cavity of the profiling module with a USB communication line is ensured.
Description
technical field [0001] The present invention relates to the technical field of calibration equipment, and more particularly, to a pressure calibration device. Background technique [0002] At present, due to the popularity of aerial camera electronic products, major companies continue to launch new aerial camera products. In order to ensure that the electronic products of the aerial camera can work normally, a pressure calibration mechanism is usually used for pressure calibration. When performing pressure calibration on the electronic products of the aerial camera, the electronic products of the aerial camera need to be connected with an external USB (Universal Serial Bus, Universal Serial Bus) communication line for data transmission. [0003] In the prior art, a through hole is opened in the cavity of the pressure calibration mechanism, through which electronic products such as drones are connected to the data receiving device, but when performing pressure calibration, t...
