Description

Technical Field

[0001] This utility model relates to an adjustable displacement sensor measuring device, belonging to the technical field of sensor measuring devices. Background Technology

[0002] The operation of a displacement sensor measurement device mainly relies on the sensor's sensing element and conversion element. The sensing element is primarily responsible for detecting changes in the displacement of the object being measured, while the conversion element converts these changes into electrical signals or other signals for output. Common types of displacement sensors include inductive, capacitive, photoelectric, Hall effect, and magnetostrictive sensors. To facilitate measurement and improve applicability, displacement sensors are typically configured as adjustable displacement sensor measurement devices.

[0003] Existing adjustable displacement sensor measurement devices have a simple structure. Because displacement sensors have high measurement accuracy, they are also quite sensitive, especially in industrial production environments. They are easily affected by contaminants such as oil stains and dust, and may also be affected by collisions or scratches from other objects, which can not only lead to a decrease in measurement accuracy but may also damage the sensor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable displacement sensor measuring device that can effectively protect the main body of the displacement sensor.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An adjustable displacement sensor measuring device includes a displacement sensor body and a sensing head. The displacement sensor body has a protective structure, including a protective shell movably mounted on the outside of the displacement sensor body. A maintenance cover is provided on top of the protective shell. A collar is fixedly mounted on one side of the displacement sensor body. A first electric telescopic rod connected to the collar is mounted on one side of the protective shell. A support groove is fixedly mounted on the bottom inner side of the protective shell. A support block connected to the displacement sensor body is movably mounted inside the support groove. Multiple sliders are fixedly mounted on the displacement sensor body. Multiple sliding grooves adapted to the sliders are formed on the inner wall of the protective shell. A spring is mounted on the other side of the protective shell, and multiple through holes are formed to cooperate with the sensing head.

[0007] Furthermore, the output end of the first electric telescopic rod and the collar are both provided with connection holes, and a plug rod is movably installed inside the connection hole, with a locking block fixedly installed at one end of the plug rod.

[0008] Furthermore, multiple grips are fixedly installed at the other end of the insertion rod.

[0009] Furthermore, the protective shell is provided with multiple heat dissipation holes.

[0010] Furthermore, a first magnetic ring is fixedly installed on the protective shell, and a second magnetic ring that is magnetically connected to the first magnetic ring is fixedly installed at the bottom of the inspection cover.

[0011] Furthermore, multiple fixed frames are fixedly installed on both sides of the protective shell, and shock absorbers connected to the protective shell are installed inside the fixed frames. One end of the shock absorber is equipped with an anti-collision block that slides inside the fixed frame.

[0012] Furthermore, multiple fixing plates are fixedly installed on the protective shell, and a second electric telescopic rod is installed at the bottom of the fixing plate. A suction cup is fixedly installed at the output end of the second electric telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application, through the design of a protective structure, effectively protects the displacement sensor during measurement, preventing it from being affected by contaminants such as oil stains and dust in industrial production environments. After the displacement sensor body is placed inside the protective shell, the support block at the bottom of the displacement sensor body is locked inside the support groove, allowing the displacement sensor body to slide on the support groove. When the displacement sensor body is in use, the first electric telescopic rod is activated to extend and push the displacement sensor body. Supported by the support block, the displacement sensor body slides from the support groove to one side of the protective shell until multiple sensing heads on the displacement sensor body extend through the through holes to the outside of the protective shell, allowing for measurement. The spring prevents the displacement sensor body from colliding with the inner wall of the protective shell when it comes into contact with it. The slider and groove reduce the friction between the displacement sensor body and the protective shell, making the first electric telescopic rod push more smoothly and reducing wear between the displacement sensor body and the protective shell. This structure not only prevents the displacement sensor body from being contaminated by pollutants, thus preventing a decrease in detection accuracy, but also prevents the displacement sensor body from being damaged by impacts.

Detailed Implementation

[0022] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1-6 As shown, this embodiment provides an adjustable displacement sensor measuring device, which includes a displacement sensor body 1 and a sensing head 2. A protective structure 3 is provided on the displacement sensor body 1. The protective structure 3 includes a protective shell 4 movably installed on the outside of the displacement sensor body 1. An inspection cover 18 is provided on the top of the protective shell 4. A collar 5 is installed on one side of the displacement sensor body 1. A first electric telescopic rod 6 connected to the collar 5 is installed on one side of the protective shell 4. A support groove 7 is fixedly installed on the bottom inner side of the protective shell 4. A support block 8 connected to the displacement sensor body 1 is movably installed inside the support groove 7. Multiple sliders 9 are fixedly installed on the displacement sensor body 1. Multiple sliding grooves 10 adapted to the sliders 9 are opened on the inner wall of the protective shell 4. A spring 11 is installed on the other side of the protective shell 4 and multiple through holes 12 that cooperate with the sensing head 2 are opened.

[0024] By setting up the protective structure 3, the displacement sensor can be effectively protected during measurement, avoiding the influence of pollutants such as oil stains and dust in the industrial production environment. After the displacement sensor body 1 is placed inside the protective shell 4, the support block 8 at the bottom of the displacement sensor body 1 is locked inside the support groove 7, allowing the displacement sensor body 1 to slide on the support groove 7. When the displacement sensor body 1 is in use, the first electric telescopic rod 6 is activated to extend and push the displacement sensor body 1. Supported by the support block 8, the displacement sensor body 1 slides from the support groove 7 to one side of the protective shell 4 until... Multiple sensing heads 2 on the displacement sensor body 1 extend through through holes 12 to the outside of the protective shell 4 for measurement. Spring 11 prevents the displacement sensor body 1 from colliding with the inner wall of the protective shell 4 when it comes into contact with it. Slider 9 and slide groove 10 reduce the friction between the displacement sensor body 1 and the protective shell 4, making the first electric telescopic rod 6 smoother when pushed and reducing wear between the displacement sensor body 1 and the protective shell 4. This structure not only prevents the displacement sensor body 1 from being contaminated by pollutants, which would reduce the detection accuracy, but also prevents the displacement sensor body 1 from being damaged by collisions.

[0025] like Figure 5 As shown, both the output end of the first electric telescopic rod 6 and the collar 5 are provided with connection holes 13. A plug rod 14 is movably installed inside the connection hole 13, and a locking block 15 is fixedly installed at one end of the plug rod 14. The plug rod 14 is inserted into the connection hole 13 to connect the collar 5 to the first electric telescopic rod 6. Then, the plug rod 14 is rotated to adjust the angle of the locking block 15 to be perpendicular to the connection hole 13, thereby fixing the collar 5 to the first electric telescopic rod 6 and preventing the first electric telescopic rod 6 from detaching from the collar 5. The plug rod 14 can be pulled out by rotating the plug rod 14 so that the angle of the locking block 15 is consistent with the connection hole 13, which facilitates the replacement of displacement sensor bodies 1 of different specifications.

[0026] like Figure 5 As shown, multiple grips 16 are fixedly installed on the other end of the insertion rod 14; the grips 16 can increase the force-bearing area of ​​the other end of the insertion rod 14, making it easier to disassemble and install the insertion rod 14.

[0027] like Figure 4 As shown, the protective shell 4 has multiple heat dissipation holes 17; the heat dissipation holes 17 are designed to facilitate the dissipation of heat generated by the displacement sensor body 1 during operation.

[0028] like Figure 2As shown, a first magnetic ring 19 is fixedly installed on the protective shell 4, and a second magnetic ring 20 is fixedly installed at the bottom of the inspection cover 18 and magnetically connected to the first magnetic ring 19. After the first magnetic ring 19 and the second magnetic ring 20 attract each other, the inspection cover 18 can be fixed on the protective shell 4. Moreover, the setting of the first magnetic ring 19 and the second magnetic ring 20 allows the inspection cover 18 to be opened directly without tools, which facilitates the maintenance of the displacement sensor body 1.

[0029] like Figure 6 As shown, multiple fixed frames 21 are fixedly installed on both sides of the protective shell 4. Shock absorbers 22 connected to the protective shell 4 are installed inside the fixed frames 21. One end of the shock absorber 22 is equipped with an anti-collision block 23 that slides inside the fixed frame 21. When an external object collides with the protective shell 4, it will first touch the anti-collision block 23. When the anti-collision block 23 is impacted, it will squeeze the shock absorber 22. The shock absorber 22 can buffer the impact force and prevent the impact force from being transmitted to the protective shell 4, thus preventing the protective shell 4 from being damaged by the impact force.

[0030] like Figure 6 As shown, multiple fixing plates 24 are fixedly installed on the protective shell 4. A second electric telescopic rod 25 is installed at the bottom of the fixing plate 24. A suction cup 26 is fixedly installed at the output end of the second electric telescopic rod 25. When the multiple second electric telescopic rods 25 are activated, they extend and drive the suction cup 26 to descend and contact the ground and adhere to it. This can improve the stability of the protective shell 4 when the displacement sensor body 1 is in use, and prevent the protective shell 4 from shaking, which would affect the measurement results of the displacement sensor body 1.

It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
