[0001] The utility model relates to the technical field of calibration, in particular to a wireless vibration sensor calibrator. Background Art

[0002] In the field of industrial automation and monitoring, wireless vibration sensors are widely used in equipment status monitoring and fault diagnosis. Since sensors may be affected by various factors such as the environment, temperature, and electromagnetic interference during long-term use, their measurement accuracy will gradually decrease. Therefore, wireless vibration sensors need to be calibrated.

[0003] Existing sensors are installed on the surface of the equipment to be detected for monitoring or on the fixed platform of the calibrator for calibration, mostly by means of bolts. For example, the vibration sensor calibrator disclosed in the utility model with announcement number CN202547771U is ultimately installed and calibrated by means of bolts. However, the connection method of the above-mentioned vibration sensor during monitoring is prone to loosening under long-term vibration, and a new connection method is needed to solve this problem. At the same time, the existing sensor calibrators lack a corresponding connection method. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the sensor is prone to loosening under long-term vibration, and a new connection method is needed to solve this problem. At the same time, the existing sensor calibrator lacks the corresponding connection method, and a wireless vibration sensor calibrator is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wireless vibration sensor calibrator includes a calibrator, wherein the calibrator includes a calibrator body and a sensor fixing table arranged on a panel of the calibrator body;

[0007] A sensor, the sensor comprising a wireless sensor body;

[0008] A connecting component is used to install the wireless sensor body on the sensor fixing table. The connecting components are respectively arranged on the surface of the sensor fixing table and the bottom end of the wireless sensor body. The connecting component includes a mounting tube and a connecting rod. The surface of the sensor fixing table is fixedly provided with a base plate. The mounting tube is fixedly provided on the top of the base plate. The bottom of the wireless sensor body is fixedly provided with a connecting plate, and the connecting rod is fixedly provided at the bottom of the connecting plate. The inner wall of the mounting tube is provided with a vertical groove, and the lower part of the inner wall of the mounting tube is provided with a horizontal groove, and the vertical groove is connected to the horizontal groove. The outer wall of the connecting rod is fixedly provided with a limit block, and the limit block cooperates with the vertical groove and the horizontal groove.

[0009] In one possible design, the calibrator further includes an output vibration amplitude display window provided on a main panel of the calibrator.

[0010] In one possible design, the calibrator further includes a power switch, a socket, a charging switch, a battery voltage detection switch, and a frequency selection switch arranged on one side of the calibrator main body panel.

[0011] In a possible design, the calibrator further includes a function selection switch and a gain adjustment potentiometer disposed on the other side of the calibrator main body panel.

[0013] In a possible design, a compression spring is sleeved on the outer wall of the connecting rod above the outer cylinder, and both ends of the compression spring are respectively fixed on the side close to the connecting plate and the outer cylinder.

[0014] In this application, during specific use, the outer tube at the bottom end of the wireless sensor body is first pushed upward to compress the compression spring, and then the connecting rod at the bottom end is inserted into the interior of the mounting tube and the limit block is moved downward along the vertical groove. The wireless sensor body is then rotated so that the limit block moves along the horizontal groove to achieve a locking effect. Finally, the outer tube is released so that the outer tube moves downward under the reset force of the compression spring. The polygonal frame will engage with the polygonal block so that the wireless sensor body cannot rotate, thereby realizing the installation of the wireless sensor body on the top of the sensor fixing table.

[0015] In the present utility model, the wireless vibration sensor calibrator can achieve the installation between the wireless sensor body and the sensor fixing table through the limit block of the connection component, and achieve the connection and preliminary fixation effect through plugging and rotating cooperation, thereby adapting and installing the sensor;

[0016] In the utility model, the wireless vibration sensor calibrator can achieve the goal of preventing the wireless sensor body from rotating after the wireless sensor body is plugged in and rotated to complete the initial installation through the polygonal frame of the connecting component, thereby achieving the final connection effect and enabling the calibration operation;

[0017] In the utility model, when in use, by cooperating with the connection components respectively arranged at the bottom end of the wireless sensor body and the surface of the sensor fixing table, when the wireless sensor body is installed on the surface of the sensor fixing table, the outer cylinder is first moved upward and then plugged and rotated.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1: Reference Figure 1-4 A calibrator includes a calibrator and a sensor. The calibrator body 1 serves as the support and control system for the entire device. A sensor mounting surface 8 is mounted on its panel for securing the wireless sensor to be calibrated. A base plate 19 is fixedly mounted on the sensor mounting surface 8. A mounting tube 20 is located on top of the base plate 19. The inner wall of the mounting tube 20 is designed with a vertical groove 21 and a connecting horizontal groove 22. This design is designed to mate with the connecting assembly at the bottom of the wireless sensor body 11 to achieve installation and locking.

[0025] A connecting plate 17 is fixed to the bottom of the wireless sensor body 11, and a connecting rod 16 is fixed to the bottom of the connecting plate 17. A limit block 15 is installed on the outer wall of the connecting rod 16. When the wireless sensor body 11 is placed on the sensor fixing table 8, the connecting rod 16 passes through the mounting tube 20, and the limit block 15 enters the vertical groove 21 and moves into the horizontal groove 22. After that, it is rotated to achieve the initial fixed installation of the wireless sensor body 11.

[0026] To enhance the stability of the connection and ease of operation, the connecting assembly also includes a polygonal block 18 and an outer cylinder 13. Polygonal block 18 is fixedly mounted on the bottom of the outer wall of the mounting cylinder 20, while outer cylinder 13 slides onto a connecting rod 16. A polygonal frame 14 is fixed to the bottom of its inner wall, which mates with polygonal block 18. Furthermore, a compression spring 12 is mounted on the portion of connecting rod 16 above outer cylinder 13. The ends of compression spring 12 are fixed to a connecting plate 17 and outer cylinder 13, respectively.

[0027] Specifically, first push the outer tube 13 at the bottom end of the wireless sensor body 11 upward to compress the compression spring 12, then insert the connecting rod 16 at the bottom end into the interior of the mounting tube 20 and move the limit block 15 downward along the vertical slot 21, then rotate the wireless sensor body 11 so that the limit block 15 moves along the horizontal slot 22 to lock it, and finally release the outer tube 13 so that the outer tube 13 moves downward under the restoring force of the compression spring 12, and the polygonal frame 14 will engage with the polygonal block 18 so that the wireless sensor body 11 cannot rotate, thereby achieving the installation of the wireless sensor body 11 on the top of the sensor fixing table 8, and finally achieving the effect that the sensor can be installed and calibrated.

[0028] Example 2: Improved on the basis of Example 1: A wireless vibration sensor calibrator, which is used in the field of wireless vibration sensor calibration, with reference to Figure 1 On the panel of the calibrator body 1, in addition to the sensor fixing table 8, there is also an output vibration amplitude display window 7, which is used to display the vibration amplitude during the calibration process in real time. On one side of the panel are provided a power switch 2, a socket 3, a charging switch 4, a battery voltage detection switch 5 and a frequency selection switch 6 to meet the power supply, charging, status detection and frequency adjustment requirements of the equipment. On the other side are provided a function selection switch 9 and a gain adjustment potentiometer 10, which are used to adjust the working mode of the calibrator and the gain of the output signal.
