[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-4 The illustrated broad-spectrum vibration sensor includes a housing 2 and a coil 7 installed inside the housing 2;

[0027] A magnet 8 is provided inside the coil 7;

[0028] A circuit board 5 is provided on the lower side of the coil 7;

[0029] Multiple detection elements 6 are fixedly connected to the upper outer wall of the circuit board 5. Multiple pins 9 are provided on the upper side of the magnet 8. An interface 4 is provided on the upper side of the housing 2. When the environment in which the sensor is located vibrates, the housing 2 moves with the vibration source. This vibration is transmitted to the coil 7 and the magnet 8 inside, causing them to move relative to each other. The magnetic flux formed by the magnetic field of the magnet 8 in the coil 7 changes, thereby generating an induced electromotive force at both ends of the coil 7, converting the mechanical energy of the vibration into electrical energy. The induced electrical signal generated by the coil 7 is transmitted to the detection elements 6 on the circuit board 5. The detection elements 6 detect the induced electrical signal and convert it into an electrical signal related to the characteristics such as vibration amplitude and frequency. After the electrical signal output by the detection elements 6 is transmitted to the circuit board 5, the amplification circuit on the circuit board 5 amplifies the weak electrical signal so that its amplitude can meet the requirements of subsequent processing. The processed digital signal is transmitted to the interface 4 through the pins 9. The interface 4 outputs the digital signal to the external device, which can further analyze, display or store these signals.

[0030] A threaded ring 16 is screwed downwards onto the upper side of the interface 4. A base plate 11 is fixedly connected to the upper outer wall of the threaded ring 16. When the sensor is not in use, in order to protect the internal components of the sensor from the influence of the external environment, the threaded ring 16 is rotated to make it tightly screwed onto the interface 4. As the threaded ring 16 rotates, the base plate 11 gradually approaches and seals the opening area of ​​the interface 4, forming a closed space to prevent dust, moisture and other substances from entering the sensor.

[0031] like Figure 3 As shown, the outer circular wall of the threaded ring 16 is fixedly connected to the outer sleeve 10, and the upper outer wall of the base plate 11 is fixedly connected to the handle 12, so that the threaded ring 16 can be rotated clockwise and counterclockwise under the action of external force.

[0032] When it is necessary to seal or open the interface 4, the operator can hold the handle 12 and use external force to rotate the threaded ring 16 clockwise or counterclockwise.

[0033] like Figure 4 As shown, an extension plate 13 is fixedly connected to the upper outer wall of the base plate 11. A groove 14 that runs vertically through the upper outer wall of the extension plate 13 is provided on the right side of the upper outer wall. Soft pads 15 are provided on the inner walls of both the front and rear ends of the groove 14 to limit the position of the circuit. Both soft pads 15 are made of sponge material.

[0034] When it is necessary to store external circuits, the circuits can be placed in the groove 14. The soft pads 15 on the inner walls of the front and rear ends of the groove 14 are made of sponge material and have good elasticity and flexibility. When the circuits are placed in the groove 14, the soft pads 15 will adhere tightly to the surface of the circuits under their own elasticity, thereby restricting the position of the circuits and preventing the circuits from shaking or shifting in the groove 14.

[0035] like Figure 1 As shown, a sealing cover 3 is provided inside the upper outer wall of the housing 2 to restrict the installation position of the interface 4, and a threaded head 1 is fixedly connected to the lower outer wall of the housing 2 to restrict the installation position of the housing 2 after being screwed into a designated threaded hole in the outside.

[0036] When the threaded head 1 is screwed into the designated external threaded hole, the tight fit of the threads can firmly restrict the position of the outer shell 2, maintain a stable position, and prevent the sensor from shifting due to vibration, external force, or other factors, thus affecting its normal operation. At the same time, the threaded connection also has a certain degree of detachability, which makes it convenient to disassemble, maintain, or replace the sensor when needed.

[0037] like Figure 1 and Figure 2 As shown, interface 4 is screwed into a designated external line. After the designated external line and interface 4 are fully screwed together, pin 9 abuts against the corresponding hole of the line.

[0038] Once the externally specified circuit is fully screwed into interface 4, pin 9 will accurately abut against the corresponding hole in the circuit. Pin 9 serves as the electrical connection point between the internal circuitry of the sensor and the external circuitry. This abutment method enables the transmission of electrical signals between the sensor and the external circuitry. The tight abutment between pin 9 and the circuit hole ensures that the electrical signals can be transmitted efficiently and accurately, reducing signal loss and interference, and ensuring that the vibration signals collected by the sensor can be reliably transmitted to external devices for processing and analysis.

[0039] The implementation principle of this embodiment is as follows: When the environment in which the sensor is located vibrates, the outer shell 2 moves along with the vibration source. This vibration is transmitted to the internal coil 7 and magnet 8, causing them to move relative to each other. The magnetic flux formed by the magnetic field of magnet 8 in coil 7 changes, thereby generating an induced electromotive force at both ends of coil 7, converting the mechanical energy of the vibration into electrical energy. The induced electrical signal generated by coil 7 is transmitted to the detection element 6 on circuit board 5. The detection element 6 detects the induced electrical signal and converts it into an electrical signal related to characteristics such as vibration amplitude and frequency. After the electrical signal output by detection element 6 is transmitted to circuit board 5, the electrical... The amplifier circuit on the circuit board 5 amplifies the weak electrical signal so that its amplitude can meet the requirements of subsequent processing. The processed digital signal is transmitted to the interface 4 through pin 9. The interface 4 outputs the digital signal to the external device, which can further analyze, display or store these signals. When the sensor is not in use, in order to protect the internal components of the sensor from the influence of the external environment, the threaded ring 16 is rotated to make it tightly screwed into the interface 4. As the threaded ring 16 rotates, the base plate 11 gradually approaches and seals the opening area of ​​the interface 4, forming a closed space to prevent dust, moisture and other substances from entering the sensor.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
