Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0023] This application discloses a high-precision pressure-sensing level.

[0024] Reference Figures 1-4 A high-precision pressure-sensing level includes a U-shaped protective base 101, a placement seat 102 inside the U-shaped protective base 101, and multiple grooves 201 evenly spaced on the top of the placement seat 102. Pressure sensors 202 are installed in the grooves 201. More specifically, the number of pressure sensors 202 is set to four to eight, and the four to eight pressure sensors 202 are evenly spaced. Rotation holes 301 are provided on the inner walls of both sides of the U-shaped protective base 101, and a rotating seat 302 is rotatably installed in the rotation holes 301. A rectangular groove 402 is provided on one side of the rotating seat 302, and a fixing pin 403 is slidably installed in the rectangular groove 402. Fixing grooves 401 are provided on both sides of the placement seat 102, and the fixing pins 403 are adapted to the corresponding fixing grooves 401.

[0025] In this embodiment, a threaded hole 501 is provided on the inner wall of one side of the rectangular groove 402. A drive screw 502 is threaded into the threaded hole 501. One end of the drive screw 502 is rotatably mounted on a fixing pin 403, and a knob 503 is fixedly mounted on the other end of the drive screw 502. A rotating groove is provided on one side of the fixing pin 403, and an annular groove is provided inside the rotating groove. An annular seat is fixedly mounted on the drive screw 502, and the annular seat is rotatably connected to the annular groove. This structural design not only allows the operator to easily and precisely control the position of the fixing pin 403 by rotating the knob 503, but also the flexible rotating connection between the fixing pin 403 and the drive screw 502 avoids the installation and disassembly efficiency of the placement seat 102 being affected by the fixing pin 403 jamming during operation, greatly improving the convenience and smoothness of user operation.

[0026] In this embodiment, a connecting plate 303 is fixedly sleeved on the rotating seat 302. The inner walls on both sides of the U-shaped protective seat 101 are provided with an insertion mechanism adapted to the connecting plate 303. The insertion mechanism includes a hemispherical groove 601, a moving groove 602, a protrusion 603 and a fixing spring 604. A plurality of hemispherical grooves 601 are opened on one side of the connecting plate 303. A moving groove 602 is opened on both sides of the inner wall of the U-shaped protective seat 101. A protrusion 603 is slidably installed in the moving groove 602. The protrusion 603 is adapted to the corresponding hemispherical groove 601. A fixing spring 604 is fixedly installed on one side of the protrusion 603 and is fixedly connected to the moving groove 602. This engagement mechanism allows the protrusion 603 to automatically engage with the hemispherical groove 601 by the elastic force of the fixed spring 604 after the placement seat 102 rotates to a specific angle, quickly and stably positioning the rotating seat 302 and ensuring that the placement seat 102 remains stable during the measurement process, effectively improving the reliability and stability of the level measurement.

[0027] In this embodiment, a controller 203 is mounted on the top of the U-shaped protective base 101, and a display 204 is mounted on the top of the controller 203. The pressure sensor 202 is electrically connected to the controller 203. Guide grooves are provided on the front and rear inner walls of the moving groove 602, and guide seats are fixedly mounted on the front and rear sides of the protrusion 603, with the guide seats slidably connected to the corresponding guide grooves. The cooperation between the guide grooves and guide seats ensures that the protrusion 603 slides smoothly within the moving groove 602, ensuring the normal operation of the insertion mechanism. At the same time, the coordinated work of the pressure sensor 202, the controller 203, and the display 204 enables the pressure signal to be quickly and accurately converted into intuitive levelness information and presented to the user, greatly improving the efficiency and accuracy of measurement data acquisition.

[0028] In this invention, when the pressure sensor 202 is used as a level, rotating the placement base 102 causes the rotating base 302 and connecting plate 303 to rotate as well. After the placement base 102 rotates 180 degrees, the pressure sensor 202 faces downwards. Under the elastic force of the fixing spring 604, the fixing spring 604 pushes the protrusion 603 into the hemispherical groove 601, thereby fixing the placement base 102. When the placement base 102 is placed on the plane to be measured, the pressure sensor 202 at different positions experiences different pressures depending on the inclination of the plane. When the left side of the plane is lower than the right side, the pressure on the left pressure sensor 202 will be greater than that on the right pressure sensor 202. By rotating the knob 503 and the drive screw 502, the drive screw 502 is rotated and moved under the action of the threaded hole 501. The drive screw 502 can move the fixing pin 403. The fixing pin 403 can be inserted into or removed from the fixing groove 401, which can realize the fixing and unfixing of the placement seat 102, making it easy to disassemble the placement seat 102 and thus making it easy to replace the pressure sensor 202.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
