Description

Technical Field

[0001] This invention relates to the field of sensor technology, specifically to a non-contact three-dimensional displacement sensor. Background Technology

[0002] In fields such as industrial inspection, equipment posture monitoring, and precision manufacturing, displacement sensors need to acquire real-time data on the three-dimensional spatial position changes of objects. Contact displacement sensors, due to direct contact with the object being measured, are prone to surface wear and mechanical interference, and have poor adaptability in high-speed motion and harsh environments. Therefore, non-contact displacement sensors have become the mainstream development direction. However, existing non-contact displacement sensors generally suffer from common problems: insufficient stability of the connection between the external data cable and the sensor interface, easily loosened by vibration, external force, etc., leading to signal transmission interruption or data acquisition distortion, affecting the continuity of the overall inspection process.

[0003] To address the issue of loose interface connections, conventional techniques often involve adding simple clips, rubber washers, or single clamping structures to the interface. These structures physically compress the data cable to secure it within the interface, using friction between the structures to counteract slight movement of the data cable. This reduces the probability of loosening and ensures the basic stability of signal transmission.

[0004] However, conventional fixing methods have obvious drawbacks: simple clips, rubber washers, and other structures lack buffering and adjustment mechanisms and dual limiting mechanisms, relying solely on a single clamping force for fixation. When the data cable is subjected to significant forces such as external insertion / removal or equipment vibration, the single clamping structure is insufficient to counteract the external force, and the clamping force is prone to failure, causing the data cable to still loosen from the interface.

[0005] Therefore, in order to address the shortcomings of the existing technology, a non-contact three-dimensional displacement sensor was proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a non-contact three-dimensional displacement sensor to solve the problems mentioned in the background art.

[0009] Furthermore, the vertical shaft and the supporting crankshaft are connected by an insertion, and the supporting crankshaft and the horizontal bar are connected by an insertion.

[0010] Furthermore, the upper crankshaft and the sensor body are connected by a plug-in connection, and the rear pressure shaft can move vertically at the middle of the inner side of the upper crankshaft.

[0011] Furthermore, the vertical shaft can move vertically inside the support cylinder, and the strip is connected to the vertical shaft by a retaining sleeve.

[0012] Furthermore, the supporting mechanism also includes a lateral tension spring, a lower limb support bar, a diagonal right-angle frame bar, an upper rectangular frame, a first rotating shaft, a second rotating shaft, and a warping piece. The diagonal right-angle frame bar is provided on the inner side of the side groove. The first rotating shaft is provided at the connection between the diagonal right-angle frame bar and the side groove. The upper rectangular frame is provided at the top of the diagonal right-angle frame bar. The warping piece is provided at the upper end of the inner side of the side groove. A lateral tension spring is provided at the middle of the lower end of the front and rear ends of the sensor body. Lower limb support bars are provided on both sides of the lateral tension spring. The second rotating shaft is provided at the connection between the lower limb support bar and the sensor body.

[0013] Furthermore, the lower limb support bar and the second rotating shaft form a rotating structure, and the first rotating shaft and the diagonal right-angle frame bar form a rotating structure.

[0014] Furthermore, the two sides of the folding piece can slide vertically inside the side groove, and the folding piece and the outside of the rear pressure shaft form a sliding structure.

[0015] Furthermore, the stabilizing mechanism also includes a low-position abutment, a third spring, a Y-shaped support column, and a sliding shaft. The inner side of the positioning groove is provided with a sliding shaft, the outer side of the sliding shaft is fitted with a slider, one end of the outer side of the sliding shaft is fitted with a third spring, the top of the slider is provided with a Y-shaped support column, and one end of the outer side of the Y-shaped support column is provided with a low-position abutment.

[0016] Furthermore, the overall structure of the low-position abutment is an L-shaped structure, and the low-position abutment is fixedly connected to the outside of the slider.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In the auxiliary mechanism of this invention, after the external data cable is inserted into the interface, the cable-clamping arc plate fits against the outer side of the data cable head. When the data cable becomes loose or moves, the cable-clamping arc plate drives the horizontal bar, the support crankshaft, and the vertical shaft to move, and the second spring assists the vertical shaft to reset. Simultaneously, the vertical shaft drives the slatted plate and the rear pressure shaft to move inside the upper crankshaft, the first spring assists the rear pressure shaft to reset, and the limiting plate restricts its excessive movement. This dual-movement combination limits the downward movement distance of the cable-clamping arc plate, reduces the impact of data cable insertion and removal force, and prevents the data cable from coming loose from the interface. 2. In the support mechanism of this invention, the rear pressure shaft moves downward, causing the folding piece to descend within the side groove, pushing the upper rectangular frame and the diagonal right-angle frame to rotate. The first rotating shaft assists the diagonal right-angle frame to rotate out, increasing the space of the sensor body and preventing impact from external components. When the diagonal right-angle frame rotates out, it pushes the lower limb support bar, and the lateral tension spring restricts its movement. The three form a triangular structure, further expanding the external space of the sensor body. 3. In the stabilizing mechanism of the present invention, the rotation of the lower limb support bar pushes the Y-shaped support column to move horizontally, causing the slider to move outside the sliding shaft, and the third spring assists the slider to return to its original position. When the Y-shaped support column moves, it causes the low-position abutment to move outward from the base plate. The low-position abutment is L-shaped and fixed to the slider, which increases the overall area of ​​the base plate and also serves as a gripping component to provide stable support for the sensor body or the base plate.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] like Figures 1 to 12 As shown, a non-contact three-dimensional displacement sensor includes: a sensor body 1, an interface 20 is provided on the top of the sensor body 1, and a base plate 28 is provided on the bottom of the sensor body 1. An auxiliary mechanism is provided on the outside of the interface 20. The auxiliary mechanism includes a wire-locking arc plate 8, which is located on both sides of the interface 20. A support mechanism is provided on the outside of the sensor body 1. The support mechanism includes a side groove 18, which is located around the outside of the sensor body 1. A stabilizing mechanism is provided at the bottom of the sensor body 1. The stabilizing mechanism includes a positioning groove 30, which is located around the perimeter of the surface of the base plate 28. The interface 20 on the top of the sensor body 1 is used to connect a pre-prepared power cord, while the base plate 28 at the bottom of the sensor body 1 helps it occupy more space in the inner shell of the external device.

[0022] Example 1: As Figures 1 to 12 As shown, the auxiliary mechanism also includes a side support foot 23, a fishback ring 14, a horizontal bar 7, a vertical shaft 9, a support crankshaft 10, a rear pressure shaft 11, an upper crankshaft 12, a first spring 13, a support cylinder 15, a second spring 16, a straight plate 17, and a limiting plate 21. A horizontal bar 7 is provided at one end of the wire clamping arc plate 8, and a support crankshaft 10 is provided at the bottom of the horizontal bar 7. A vertical shaft 9 is provided at the middle of the bottom of the support crankshaft 10, and a side support foot 23 is sleeved on the upper end of the outside of the vertical shaft 9. A straight piece 17 is fitted in the middle of the outside of the vertical shaft 9. A second spring 16 is provided at the upper and lower ends of the straight piece 17. A support cylinder 15 is fitted at the lower end of the outside of the vertical shaft 9. A fish back ring 14 is fitted in the middle of the outside of the interface 20. A rear pressure shaft 11 is provided at one end of the bottom of the straight piece 17. A limiting piece 21 is fitted at the bend of the rear pressure shaft 11. A first spring 13 is fitted at the lower end of the outside of the rear pressure shaft 11. An upper crankshaft 12 is also fitted at the lower end of the outside of the rear pressure shaft 11. The vertical shaft 9 is inserted into the support crankshaft 10, and the support crankshaft 10 is inserted into the horizontal bar 7. The upper crankshaft 12 and the sensor body 1 are connected by a plug-in connection, and the rear pressure shaft 11 can move vertically at the middle of the inner side of the upper crankshaft 12; The vertical shaft 9 can move vertically inside the support cylinder 15, and the straight piece 17 is connected to the vertical shaft 9 by a clamp. When the user inserts the external data cable into the inside of the interface 20, the cable clamping arc plate 8 will fit against the outside of the data cable head. When the data cable becomes loose or moves outward, the cable clamping arc plate 8 will be forced to move the horizontal bar 7 along the bottom of the sensor body 1. The horizontal bar 7 will drive the support crankshaft 10 to move. The support crankshaft 10 will drive the vertical shaft 9 to move inside the support cylinder 15. The second spring 16 will help the vertical shaft 9 to reset after losing power. Furthermore, when the vertical shaft 9 moves, it will drive the strip 17 to move. When the strip 17 moves, it will drive the rear pressure shaft 11 to move in the middle of the inner side of the upper crankshaft 12. The first spring 13 helps the rear pressure shaft 11 to reset after losing power. The limiting piece 21 prevents the rear pressure shaft 11 from moving excessively in the middle of the inner side of the upper crankshaft 12. Therefore, the distance and space of movement of the rear pressure shaft 11 and the strip 17 are limited. The moving combination of the rear pressure shaft 11 and the upper crankshaft 12 and the moving combination of the support cylinder 15 and the vertical shaft 9 will double limit the downward movement distance of the cable clamping arc plate 8. Therefore, the influence of the external data cable insertion and removal force on the cable clamping arc plate 8 will be reduced, thereby preventing the external data cable from coming loose from the inside of the interface 20.

[0023] Example 2: Figures 1 to 12 As shown, the supporting mechanism also includes a lateral tension spring 2, a lower limb support bar 3, a diagonal right-angle frame bar 4, an upper rectangular frame 5, a first rotating shaft 6, a second rotating shaft 19, and a folding piece 22. The diagonal right-angle frame bar 4 is provided on the inner side of the side groove 18. The first rotating shaft 6 is provided at the connection between the diagonal right-angle frame bar 4 and the side groove 18. The upper rectangular frame 5 is provided on the top of the diagonal right-angle frame bar 4. The folding piece 22 is provided at the upper end of the inner side of the side groove 18. The lateral tension spring 2 is provided at the middle of the lower end of the front and rear ends of the sensor body 1. The lower limb support bars 3 are provided on both sides of the lateral tension spring 2. The second rotating shaft 19 is provided at the connection between the lower limb support bars 3 and the sensor body 1. The lower limb support bar 3 and the second rotating shaft 19 form a rotating structure, and the first rotating shaft 6 and the diagonal right-angle frame bar 4 form a rotating structure. The two sides of the folding piece 22 can slide vertically inside the side groove 18, and the folding piece 22 and the outside of the rear pressure shaft 11 form a sliding structure. When the rear pressure shaft 11 moves downward inside the upper crankshaft 12, the rear pressure shaft 11 drives the warp flap 22 to descend. The warp flap 22 moves downward inside the side groove 18. When the bottom of the warp flap 22 moves downward, it pushes the upper top rectangular frame 5 to rotate. The upper top rectangular frame 5 drives the diagonal right angle frame 4 to rotate. The first rotating shaft 6 helps the diagonal right angle frame 4 to rotate out inside the side groove 18, thereby increasing the overall space of the sensor body 1 and preventing external data cables or components from hitting the outside of the sensor body 1. Furthermore, when the diagonal bracing right-angle frame 4 is rotated outward from the inside of the side groove 18, the bottom of the diagonal bracing right-angle frame 4 will slide on the top of the lower limb support 3. At the same time, when the extension limit of the lateral tension spring 2 reaches its limit, the lower limb support 3 stops being pushed by the diagonal bracing right-angle frame 4. At this time, the lower limb support 3, the diagonal bracing right-angle frame 4 and the edge of the sensor body 1 form a triangular structure, thereby increasing the overall external space of the sensor body 1.

[0024] Example 3: Figures 1 to 12As shown, the stabilizing mechanism also includes a low-position abutment 26, a third spring 25, a Y-shaped support column 27, and a sliding shaft 29. The inner side of the positioning groove 30 is provided with a sliding shaft 29, and a slider 24 is sleeved on the outside of the sliding shaft 29. A third spring 25 is sleeved on one end of the outside of the sliding shaft 29. A Y-shaped support column 27 is provided on the top of the slider 24, and a low-position abutment 26 is provided on one end of the outside of the Y-shaped support column 27. The overall structure of the low-position abutment 26 is L-shaped, and the low-position abutment 26 is fixedly connected to the outside of the slider 24; When the lower limb support bar 3 rotates, it pushes the Y-shaped support column 27 to move horizontally. The Y-shaped support column 27 drives the slider 24 to move outside the sliding shaft 29 inside the positioning groove 30. The third spring 25 helps the slider 24 to reset after losing power. When the Y-shaped support column 27 moves, it drives the low-position abutment plate 26 to move outward of the base plate 28. In this way, the low-position abutment plate 26 can increase the overall area of ​​the base plate 28. The low-position abutment plate 26 can also serve as a gripping component to provide more stable support for the sensor body 1 or the base plate 28.
