Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a novel pressure sensor. Background Art

[0002] Pressure sensors are used to test the pressure of objects, liquids and gases. Pressure sensors used to test gases usually connect the gas pipe to the end of the pressure sensor. The gas then enters the pressure sensor for measurement, and the measured data is then displayed on a display for intuitive viewing.

[0003] However, most of the gas pipelines and pressure sensors are connected through threaded heads, and the connection between the threaded heads needs to be rotated. Therefore, when the space is relatively narrow, the sensor and the pipeline are not easy to rotate, which makes the installation inconvenient. For this reason, we propose a new type of pressure sensor to solve the above problem. Utility Model Content

[0030] For a detailed description of the moving block 12 in this embodiment, please refer to Figure 3 and Figure 4 The end of the moving block 12 is inclined, and then a sliding block 13 is arranged at the bottom end of the moving block 12, and a sliding groove 14 is opened on the outer wall of the mounting sleeve 5, and then the sliding block 13 extends to the inside of the sliding groove 14, and a fixed shaft rod 15 is arranged inside the sliding groove 14, and at the same time, the sliding block 13 is sleeved on the outside of the fixed shaft rod 15, so that a return spring 16 is sleeved on the outside of the fixed shaft rod 15, and then one end of the return spring 16 is fixedly connected to the sliding block 13, and the other end of the return spring 16 is fixedly connected to the inner wall of the sliding groove 14.
