[0030] The air pressure sensor includes a front shell 3 and a rear shell 4, the front shell 3 cooperates with the rear shell 4, and a plurality of connection positioning holes are opened on the side, and a positioning rod 5 is commonly penetrated in two adjacent connection positioning holes, a connecting plate 6 is fixedly provided at the end of the positioning rod 5, a supporting plate 7 is fixedly provided between two adjacent connecting plates 6, a moving frame 8 is commonly fixedly provided on the top of the two upper connecting plates 6, and two symmetrically arranged elastic components are provided between the moving frame 8 and the rear shell 4, and the elastic component includes a fixing rod 12, the fixing rod 12 is fixedly connected to the rear shell 4, and is slidably arranged inside the moving frame 8, and a first spring 13 is provided on the rod wall sleeve of the fixing rod 12, and the two ends of the first spring 13 are respectively fixedly connected to the fixing rod 12 and the moving frame 8;

[0031] A mounting plate 9 is fixedly provided at the upper end of the rear shell 4 , a vertical rod 10 is rotatably provided inside the mounting plate 9 , a push block 11 is fixedly sleeved at the lower end of the vertical rod 10 , and the push block 11 is cam-shaped and contacts and cooperates with the back side of the moving frame 8 .

[0032] When the air pressure sensor is in use, the front shell 3 and the rear shell 4 of the air pressure sensor can be stably connected by plugging the positioning rod 5 into the positioning hole and pressing the connecting plate 7 and the first spring 13. At this time, the air pressure sensor monitors the air pressure and controls the pressure regulating valve 1 through the PLC control 2 according to the detection result, so that the pressure regulating valve 1 can quickly and automatically adjust the air pressure to ensure that the equipment can operate stably under stable air pressure. When it is necessary to detect the internal sensor element of the air pressure sensor, the vertical rod 10 can be rotated so that the vertical rod 10 drives the push block 11 to rotate, so that the push block 11 pushes the movable frame 8, so that the movable frame 8 can slide along the fixed rod 12 and stretch the first spring 13. At this time, the movable frame 8 can drive the connecting plate 7 to move, so that the positioning rod 5 is pulled out of the positioning hole. At this time, the front shell 3 can be removed from the rear shell 4, and the internal sensor elements can be detected.

[0033] Example 2
