[0002] A sensor is a device that converts signals into electrical signals. Among them, vibration sensors have higher sensitivity and a wider frequency response range. However, since they are mostly cylindrical, this shape makes it difficult to fix them to the object being measured. Glue is usually used to stick the vibration sensor to the surface of the object being measured. However, this method is prone to cause the glue to fail as the temperature rises during the operation of the sensor, causing it to fall off and damage the sensor. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Please combine Figure 1 and Figure 2 The first embodiment of the utility model provides a fixing structure 1 for installing a sensor and an object to be measured, comprising a sensor housing 10, a fixing plate 11 and an assembly component 12. The fixing plate 11 is arranged between the sensor housing 10 and the assembly component 12. The assembly component 12 comprises an assembly body 120 and a stud 121. The stud 121 is sleeved on the assembly body 120. The sensor housing 10 is fixed to the object to be measured by bolts through the assembly body 120.

[0028] It is explained that the inner diameter of the stud 121 has threads, and the outer diameter of the assembly 120 is provided with threads corresponding to the inner diameter of the stud 121, and the threads between the two match to achieve a fixed connection between the stud 121 and the assembly 120.

[0029] Furthermore, a positioning hole 110 is provided on the fixing plate 11 , and an annular step 100 is provided on the sensor housing 10 corresponding to the outer diameter of the fixing plate 11 , and the stud 121 is sleeved on the fixing plate 11 and the annular step 100 .

[0030] Preferably, four screw holes are respectively opened in the spaced positioning holes 110 on the fixing plate 11 and are arranged diagonally, and corresponding screw holes are opened one by one on the annular step 100, and the sensor housing 10 and the fixing plate 11 are fixed by screws through the screw holes; in actual use, after the fixing plate 11 and the metal housing are fixed, the stud 121 is sleeved on the fixing plate 11 and the annular step 100 to be fixed, and the assembly 120 and the stud 121 are threadedly connected.

[0031] It can be explained that the cooperation between the positioning hole 110 and the screw hole can provide an accurate installation position for the sensor housing 10, prevent it from shifting or tilting, and keep it in a stable position during the installation process, avoiding the influence of the parameter accuracy of the object under test due to the installation error, and this setting makes the installation of the sensor housing 10 easy and quick.

[0032] Please combine Figure 2 and Figure 3Furthermore, the assembly body 120 is a first assembly part, and a first through hole 1200 and a second through hole 1201 connected to the first through hole 1200 are respectively opened along the central axis of the first assembly part. When the sensor housing 10 is fixed to the object to be measured with bolts through the assembly body 120, the first through hole 1200 is close to the fixing plate 11.

[0033] Furthermore, the outer diameter of the first through hole 1200 gradually decreases away from the fixing plate 11 .

[0034] Specifically, the first assembly part is fixed to the object to be measured by screws, which is suitable for the case where the shell of the object to be measured is flat and can be punched, wherein the setting of the first through hole 1200 and the second through hole 1201 enables the sensor housing 10 to be fixed to the object to be measured with bolts through the through hole setting of the first assembly part, so as to improve the convenience and firmness of equipment installation; in addition, the outer diameter of the first through hole 1200 gradually decreases away from the fixing plate 11, and this setting facilitates the concealment of the bolt connection between the first assembly part and the object to be measured, avoiding the additional height generated by the bolts, which may easily affect the stability between the object to be measured and the sensor.

[0035] Please combine Figure 2 and Figure 4-Figure 5 The second embodiment of the utility model provides a fixed structure 2 for installing a sensor and an object to be measured, which is different from the fixed structure 1 for installing a sensor and an object to be measured provided in the first embodiment in that: the assembly 120 is a second assembly part, and the second assembly part is provided with a positioning block 20 corresponding to the positioning hole 110, and the positioning block 20 is penetrated through the positioning hole 110 and abuts against the annular step 100. Through the cooperation between the positioning block 20 and the positioning hole 110, the positioning accuracy of the assembly 120 and the sensor housing 10 can be guaranteed during the installation process, and the abutment of the positioning block 20 and the annular step 100 ensures the stability of the assembly 120.

[0036] It can be explained that the sensor has a specified measuring direction, and the positioning hole 110 of the fixing plate 11 determines the installation direction of the fixing plate 11 according to the measuring direction, and further determines the installation direction of the second assembly part.

[0037] Furthermore, a receiving groove 21 is provided at one end of the second assembly part opposite to the fixed plate 11, and at least two magnetic blocks 22 are arranged in parallel and at intervals in the receiving groove 21, and the positioning blocks 20 are perpendicular to the two magnetic blocks 22. This arrangement enables the positioning blocks 20 and the magnetic blocks 22 to cooperate with each other to jointly achieve more precise positioning and control.

[0038] Furthermore, the magnetic block 22 includes a slope section 220 and a straight section 221 connected to the slope section 220 , and the straight section 221 is close to the bottom of the accommodating groove 21 .

[0039] Preferably, a strong magnet is provided between the straight section 221 and the bottom of the receiving groove 21, that is, the magnetic attraction of the strong magnet ensures that the magnetic block 22 and the second assembly part are firmly installed.

[0040] Specifically, the second assembly part and the object to be measured are magnetically fixed based on the magnetic block 22, which is suitable for the object to be measured with a curved outer shell. It can be explained that the slope section 220 and the straight section 221 together constitute the basic form of the magnetic block 22. The straight section 221 is arranged close to the bottom of the accommodating groove 21 to ensure the stability of the magnetic block 22. The straight section 221 plays a supporting role in the structure of the magnetic block 22 to ensure the stability and reliability of the magnetic block 22 under various working conditions. The setting of the slope section 220 enables the assembly 120 to fit better with the curved object to be measured, and the installation is more stable.

[0041] It can be understood that the sensor housing 10 and the object to be measured are fixed by the assembly 120, wherein the fixing methods are bolts and magnetic attraction. The user can select the corresponding assembly method according to the on-site environment, so that the connection between the sensor and the object to be measured is more firm, and the installation method is simple, which is conducive to improving the convenience of operation, and has a wider range of applications and higher flexibility. It can also reduce the equipment failure rate caused by unstable connection, and can stably measure various parameters of the object to be measured to improve the measurement accuracy. In addition, the fixing plate 11 arranged between the sensor housing 10 and the assembly 120 can further play a supporting and stabilizing role.

[0042] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
