[0004] The existing probes are integrally formed and installed on the test equipment. After the probes of equal diameter hit the surface of an object, the vibration on the surface of the object is transmitted to the test equipment through the probes, and then the vibration-related data is obtained through the sensor on the test equipment, resulting in the defect of error in the measurement data.

[0005] Based on this, the utility model designs a probe with high sensitivity to solve the above problems. Utility Model Content

[0008] By adopting the above technical solution, when measuring physical quantities related to vibration, the probe body is pressed against the object, and the deformation of the probe is directly measured through the strain gauge. At the same time, the analog signal is transmitted to the test equipment through the electrical connection socket for conversion, so that the measured data is more accurate.

[0009] Preferably, the probe body includes a contact portion, a strain portion and a connecting portion, the connecting portion is fixedly arranged on the mounting base, the strain portion is fixedly arranged on the connecting portion, the elastic strain gauge is fixedly arranged in the strain portion, and the contact portion is fixedly arranged on the strain portion.

[0010] By adopting the above technical solution, when measuring the vibration of an object, the contact part contacts the object, ensuring that the contact point between the probe body and the object is consistent each time, which helps to improve the accuracy of the measurement.

[0011] Preferably, a clearance groove is provided on the strain portion.

[0012] By adopting the above technical solution, the strain of the probe body caused by the contact portion contacting the object is concentrated on the strain portion, so that when the elastic strain gauge arranged in the strain portion measures the vibration of the strain portion, the measured data is more accurate.

[0013] Preferably, a mounting groove is provided on the mounting base.

[0014] By adopting the above technical solution, when the mounting base is set on the test equipment, the mounting base is further limited by the mounting groove, so that the mounting base is set more firmly.

[0015] Preferably, a reinforcement block is fixedly provided on the mounting base.

[0016] By adopting the above technical solution and setting the reinforcement block, it is possible to avoid the situation where the mounting base and the probe body are broken due to operational errors.

[0017] In summary, the present application has the following beneficial technical effects: when measuring physical quantities related to vibration, the contact part is pressed against the object, the vibration on the object is transmitted to the strain part through the contact part, the deformation of the strain part is directly measured by the strain gauge, and at the same time, the analog signal is transmitted to the test equipment through the electrical connection socket for conversion, so that the measured data is more accurate, which has the advantage of accurate measurement data.
