Description

Technical Field

[0001] This utility model belongs to the field of inductive displacement sensors, specifically, it relates to an inductive displacement sensor that is easy to assemble. Background Technology

[0002] An inductive displacement sensor is a measuring device based on the principle of electromagnetic induction. It converts the change in displacement (including linear or angular displacement) of the measured object into a change in the inductance of a coil, and then processes the signal through subsequent circuits to output an electrical signal (such as voltage, current, frequency, etc.) that corresponds to the displacement. It can accurately detect small or large displacements and is widely used in industrial automation, machinery manufacturing, aerospace, precision measurement and other fields. However, existing inductive displacement sensors lack a protective cover design on the head and do not have copper rings or gaskets. When the sensor is subjected to high air pressure, there is a certain risk of failure.

[0003] Chinese patent publication number CN222104639U discloses an inductive displacement sensor. This device improves the pressure resistance of the inductive displacement sensor by setting a protective cover and sealing mechanism at one end of the guide rod. At the same time, a skeleton is set on the outer periphery of the guide rod, and the skeleton is made of wear-resistant material, which increases the service life of the sensor, reduces wear between the sensor and the guide rod, ensures the accuracy of the sensor, and greatly improves its stability. However, when this device needs to be installed in a designated position, it requires the cooperation of multiple sets of accessories to install, and the installation steps are too cumbersome, time-consuming and labor-intensive.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Please see Figure 1-7As shown, this embodiment provides an easily assembled inductive displacement sensor, including a sensor body 1, on which multiple sets of mounting components 9 are provided. The mounting components 9 are configured to install the sensor body 1 at a designated position. The mounting components 9 include an elastic plate 91, on which two clamping plates 92 are fixedly mounted relative to each other. The sensor body 1 has multiple slots 2 embedded along its length direction for engaging the clamping plates 92 and the elastic plate 91. The elastic plate 91 is elastic and has multiple limiting teeth 93, which are fixedly mounted on the ends of the two clamping plates 92 away from the elastic plate 91. The slots 2 are provided with limiting grooves 3 for limiting the multiple limiting teeth 93. There are multiple limiting grooves 3, which extend along the circumference of the slots 2.

[0035] Specifically, when installing the sensor body 1, the sensor body 1 is passed through the through hole on the mounting plate 11 (see reference). Figure 6 (As shown), then, select the slot 2 on the sensor body 1 near the mounting plate 11, align the clamping plates 92 of the two sets of mounting components 9 with the entrance of the slot 2, and pull the two clamping plates 92 away from each other to make the elastic plate 91 slightly deform (because the elastic plate 91 is elastic), so that the clamping plate 92 can be inserted into the slot 2. After insertion, release the external force, the elastic plate 91 rebounds, and the clamping plate 92 fits tightly against the inner wall of the slot 2 under the action of elastic force, completing the initial fixation. After the clamping plate 92 is fully inserted into the slot 2, the limiting teeth 93 at its end engage with the multiple limiting grooves 3 in the slot 2 to form a mechanical lock, preventing the mounting components 9 from sliding along the length of the sensor body 1 or falling off radially. Through the synergistic action of the two sets of mounting components 9, the sensor body 1 is stably installed on the mounting plate 11, completing the assembly. The overall structure has simple installation steps, high installation efficiency, strong connection stability, good installation flexibility, and is easy to disassemble and maintain.

[0036] It should be noted that, in this embodiment, the material of the elastic plate 91 can be spring steel, TPE, PE, etc. The fixing method of the clamping plate 92 and the elastic plate 91 is the prior art and will not be described here. The material of the clamping plate 92 can be rigid plastic.

[0037] In this embodiment, as Figures 1 to 4 As shown, the slot 2 is a ring-shaped structure arranged along the circumference of the sensor body 1, the elastic plate 91 is an arc-shaped structure, and the clamping plate 92 is an arc-shaped structure with a gradually increasing cross-sectional area from one end connected to the elastic plate 91 to the other end. The clamping plate 92 and the elastic plate 91 can fit against the inner wall of the slot 2. Specifically, the inner walls of the clamping plate 92 and the elastic plate 91 can fit against the inner wall of the slot 2, thereby improving the fit between the mounting assembly 9 and the sensor body 1, reducing the gap after assembly, and improving the connection stability. The shape of the clamping plate 92 makes it easy for users to operate the clamping plate 92 and improves the user experience.

[0038] In this embodiment, as Figures 1 to 5 As shown, the clamping plate 92 includes an integrally formed arc-shaped plate 921 and a counterweight plate 922. The arc-shaped plate 921 is fixedly connected to the elastic plate 91. The counterweight plate 922 is located at the end of the arc-shaped plate 921 away from the elastic plate 91. The limiting groove 3 is fixedly installed on the counterweight plate 922. The counterweight plate 922 defines a chamber 10 for filling with counterweight material. Specifically, the chamber 10 can be filled with heavy calcium carbonate and other substances, which are among the most commonly used mineral fillers and are inexpensive. By increasing the end weight through the counterweight plate 922, the tightness of the clamping plate 92 and the slot 2 is improved, the limiting effect is strengthened, and the installation component 9 is prevented from falling off.

[0039] In this embodiment, as Figures 1 to 4 As shown, rubber pads 7 are fixedly installed on both sides of the clamping plate 92. Specifically, in this embodiment, the rubber pads 7 do not contact the slot 2. The rubber pads 7 are used to fill the gap between the clamping plate 92 and the mounting plate 11, increase the friction with the mounting plate 11, and improve the stability of the mounting assembly 9.

[0040] In this embodiment, as Figures 1 to 4 As shown, two fixing plates 4 are fixedly installed on both sides of the elastic plate 91. Fixing holes 5 are provided through the fixing plates 4. Specifically, refer to Figure 7 As shown, when no through holes are provided on the mounting plate 11, the mounting component 9 can be positioned by the fixing plate 4 and the fixing hole 5, thereby enabling the installation of the sensor body 1 and increasing the versatility of the device.

[0041] In this embodiment, as Figures 2 to 4 As shown, multiple reinforcing protrusions 6 are fixedly installed on the outer wall of the elastic plate 91 along its circumference. Specifically, the reinforcing protrusions 6 on the outer wall of the elastic plate 91 are distributed along the circumference. By increasing the local structural thickness, the overall strength and deformation resistance of the elastic plate 91 are improved, preventing the elastic plate 91 from excessively bending or breaking during repeated assembly or long-term stress, thereby enhancing the structural stability of the elastic plate 91, extending its service life, and reducing the rework rate caused by damage to the elastic plate 91.

[0042] In this embodiment, as Figures 2 to 4 As shown, the inner wall of the elastic plate 91 is embedded with multiple deformation grooves 8 along its circumference. Specifically, the deformation grooves 8 on the inner wall of the elastic plate 91 are distributed along the circumference, providing deformation space for the elastic plate 91, avoiding stress concentration caused by the elastic plate 91 being restricted in deformation, reducing the risk of breakage, protecting the structure of the elastic plate 91, making installation easier, and improving assembly efficiency.

[0043] Working principle:

[0044] When installing the sensor body 1, pass the sensor body 1 through the through hole on the mounting plate 11 (see reference). Figure 6(As shown), then, select the slot 2 on the sensor body 1 near the mounting plate 11, align the clamping plates 92 of the two sets of mounting components 9 with the entrance of the slot 2, and pull the two clamping plates 92 away from each other to make the elastic plate 91 slightly deform (because the elastic plate 91 is elastic), so that the clamping plate 92 can be inserted into the slot 2. After insertion, release the external force, the elastic plate 91 rebounds, and the clamping plate 92 fits tightly against the inner wall of the slot 2 under the action of elastic force, completing the initial fixation. After the clamping plate 92 is fully inserted into the slot 2, the limiting teeth 93 at its end engage with the multiple limiting grooves 3 in the slot 2 to form a mechanical lock, preventing the mounting components 9 from sliding along the length of the sensor body 1 or falling off radially. Through the synergistic action of the two sets of mounting components 9, the sensor body 1 is stably installed on the mounting plate 11, completing the assembly. The overall structure has simple installation steps, high installation efficiency, strong connection stability, good installation flexibility, and is easy to disassemble and maintain.
