[0007] Preferably, the drive assembly includes a motor, a support column, and an outer frame. The support column is mounted on the storage box, and the outer frame is mounted on one end of the support column. The motor is mounted on the outer frame.

The storage box is equipped with a support frame, the support frame is equipped with a side block, the side block is equipped with a support ring, and a rotating rod is rotatably mounted on the support ring. One end of the rotating rod is connected to the output end of the motor.

The other end of the base rod is connected to the connecting plate, the compensation rod is mounted on the connecting plate, one end of the compensation rod is connected to the adjusting plate, and the sensor is mounted on the adjusting plate.

[0011] Preferably, the guide assembly includes a limiting rod, a limiting ring, a second connecting block, and a connecting post. The limiting rod is mounted on the connecting plate, the limiting ring is slidably mounted on the limiting rod, the second connecting block is mounted on the limiting ring, and the connecting post is mounted on the second connecting block. One end of the connecting post is connected to the adjusting plate.

[0012] Preferably, the sliding assembly includes a slide rod, a first connecting block, and a side rod.

The slide rod is mounted on the first connecting block, and the storage box has a sliding hole that cooperates with the slide rod.

[0013] Preferably, the extrusion assembly includes a connecting rod, an auxiliary extrusion block, a guide rod, a spring, a main extrusion block, and a support rod. The support rod is mounted on the connecting plate, and the main extrusion block is mounted on one end of the support rod. The guide rod is slidably mounted on the storage box, and the auxiliary extrusion block is mounted on one end of the guide rod. The connecting rod is mounted on the auxiliary extrusion block, and the guide rod is connected to the storage box via a spring.

[0014] Preferably, the protective component includes a protective mesh panel and a movable groove, with the protective mesh panel installed at one end of the connecting rod, and the storage box having a movable groove that cooperates with the protective mesh panel.

[0015] Beneficial technical effects of the present invention: According to the high-precision sensor of the present invention, the base plate, support frame, and base frame cooperate to facilitate the support of the storage box, and the storage box facilitates the storage of the sensor. The outer frame and support column cooperate to facilitate the support of the motor. The support ring, side block, and support frame cooperate to facilitate the support of the rotating rod. The bottom rod facilitates the support of the rack. The sliding connection between the sliding rod and the sliding hole facilitates the guiding and limiting of the connecting plate. The side rod and the first connecting block cooperate to facilitate the support of the sliding rod. The motor is installed to start the motor. It can drive the rotating rod to rotate, which in turn drives the rack to move. The rack moves, which in turn drives the connecting plate to move. The connecting plate moves, which in turn drives the sensor to move, thus moving the sensor into the storage box for storage. When the connecting plate moves, it can drive the main extrusion block to move, thus moving the main extrusion block away from the auxiliary extrusion block. At this time, the spring extends and retracts, which in turn drives the guide rod to slide on the storage box. When the guide rod slides, it can drive the protective mesh plate to move, thus closing the storage box. This facilitates the storage and protection of the sensor, and can protect the sensor from collision damage when it is not in use.

[0016] Since the compensating rod and the sensor are made of the same metal material, under the same coefficient of thermal expansion and height, the increase in thermal expansion and contraction of the sensor and the compensating rod is the same, but their directions are exactly opposite. That is, when the temperature rises, the compensating rod extends backward and the sensor extends forward, and vice versa. This can cancel each other out, thereby minimizing temperature drift.

A rotating component is mounted on the driving component, a moving component is mounted on the rotating component, a sensor component is mounted on the moving component, a pressing component is mounted on the sensor component, a sliding component is mounted on the pressing component, a protective component is mounted on the storage component, and a guiding component is mounted on the sensor component. The storage component includes a base plate 1, a support frame 11, a base frame 12, and a storage box 13. The base frame 12 is mounted on the base plate 1, the support frame 11 is mounted on the base frame 12, and the storage box 13 is mounted on the support frame 11. By setting the base plate 1, the support frame 11, and the base frame 12 to cooperate with each other, the storage box 13 can be easily supported. 3. The sensor 71 can be easily stored. The drive assembly includes a motor 5, a support column 51, and an outer frame 52. The support column 51 is mounted on the storage box 13, and the outer frame 52 is mounted on one end of the support column 51. The motor 5 is mounted on the outer frame 52. By setting the outer frame 52 and the support column 51 to cooperate with each other, the motor 5 can be easily supported. The rotating assembly includes a support ring 8, a side block 81, a support frame 82, and a rotating rod 83. The support frame 82 is mounted on the storage box 13, the side block 81 is mounted on the support frame 82, the support ring 8 is mounted on the side block 81, and the rotating rod 83 is rotatably mounted on the support ring 8. One end of the rotating rod 83 is connected to the output end of the motor 5. By setting the support ring 8, the side block 81, and the support frame 82 to cooperate with each other, the rotating rod 83 can be easily rotated. 3. Support is provided by the moving component, which includes a rack 4, a gear 41, and a base rod 42. The gear 41 is mounted on the rotating rod 83, and the base rod 42 is mounted on the sensor assembly. One end of the base rod 42 is fitted with a rack 4 that meshes with the gear 41. The base rod 42 facilitates support for the rack 4. The sliding component includes a slide rod 3, a first connecting block 31, and a side rod 32. The side rod 32 is mounted on the connecting plate 7, and the first connecting block 31 is mounted on one end of the side rod 32. The slide rod 3 is mounted on the first connecting block 31. The storage box 13 has a sliding hole that cooperates with the slide rod 3. By setting the slide rod 3 to slide in the sliding hole, the connecting plate 7 can be guided and limited. By setting the side rod 32 to cooperate with the first connecting block 31, the sliding plate 7 can be guided and limited. The compression assembly, supported by rod 3, includes a connecting rod 6, an auxiliary compression block 61, a guide rod 62, a spring 63, a main compression block 64, and a support rod 65. The support rod 65 is mounted on the connecting plate 7, and the main compression block 64 is mounted at one end of the support rod 65. A guide rod 62 is slidably mounted on the storage box 13, and the auxiliary compression block 61 is mounted at one end of the guide rod 62. The connecting rod 6 is mounted on the auxiliary compression block 61. The guide rod 62 is connected to the storage box 13 via the spring 63. The support rod 65 facilitates support for the main compression block 64, the connecting rod 6 facilitates support for the auxiliary compression block 61, and the guide rod 62 facilitates guidance and limiting of the auxiliary compression block 61. The protective assembly includes a protective mesh plate 2 and a moving groove 21.A protective mesh plate 2 is installed at one end of the connecting rod 6. A movable groove that cooperates with the protective mesh plate 2 is provided on the storage box 13. A motor 5 is installed; when the motor 5 starts, it drives the rotating rod 83 to rotate. When the rotating rod 83 rotates, it drives the rack 4 to move. When the rack 4 moves, it drives the connecting plate 7 to move. When the connecting plate 7 moves, it drives the sensor 71 to move, thus moving the sensor 71 into the storage box 13 for storage. When the connecting plate 7 moves, it drives the main extrusion block 64 to move, thus moving the main extrusion block 64 away from the auxiliary extrusion block 61. At this time, the spring 63 extends and retracts, thus driving the guide rod 62 to slide on the storage box 13. When the guide rod 62 slides, it drives the protective mesh plate 2 to move, thus closing the storage box 13. This facilitates the storage and protection of the sensor 71, preventing it from being damaged by impact when not in use.

[0021] In this embodiment, as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, the sensor assembly includes a connecting plate 7, a sensor 71, an adjusting plate 72, and a compensating rod 73. The other end of the base rod 42 is connected to the connecting plate 7. The compensating rod 73 is mounted on the connecting plate 7, and one end of the compensating rod 73 is connected to the adjusting plate 72. The sensor 71 is mounted on the adjusting plate 72. The guide assembly includes a limiting rod 9, a limiting ring 91, a second connecting block 92, and a connecting post 93. The limiting rod 9 is mounted on the connecting plate 7, and the limiting ring 91 is slidably mounted on the limiting rod 9. The second connecting block 92 is mounted on the limiting ring 91, and the connecting post 93 is mounted on the second connecting block 92. One end of the connecting post 93 is connected to the adjusting plate 72. The connection, through the sliding connection of the limiting ring 91, facilitates the guiding and limiting of the adjustment plate 72 and the sensor 71. The connection column 93 facilitates the support of the adjustment plate 72. Since the compensation rod 73 and the sensor 71 are made of the same metal material, under the condition of the same coefficient of thermal expansion and height, the thermal expansion and contraction increment of the sensor 71 and the compensation rod 73 are the same, but their directions are exactly opposite. That is, when the temperature rises, the compensation rod 73 extends backward and the sensor 71 extends forward, and vice versa. This can play a mutual cancellation role, thereby minimizing temperature drift.

[0022] In this embodiment, as Figures 1-11 As shown, the working process of a high-precision sensor provided in this embodiment is as follows: Step 1: The motor 5 starts and drives the rotating rod 83 to rotate. When the rotating rod 83 rotates, it drives the rack 4 to move. When the rack 4 moves, it drives the connecting plate 7 to move. When the connecting plate 7 moves, it drives the sensor 71 to move, and then moves the sensor 71 to the storage box 13 for storage. Step 2: When the connecting plate 7 moves, it drives the main extrusion block 64 to move, thereby moving the main extrusion block 64 away from the auxiliary extrusion block 61. At this time, the spring 63 extends and retracts, thereby driving the guide rod 62 to slide on the storage box 13. When the guide rod 62 slides, it drives the protective mesh plate 2 to move, thereby closing the storage box 13 and storing and protecting the sensor 71. This allows the sensor 71 to be stored and protected when it is not in use.

[0023] In summary, in this embodiment, the high-precision sensor, through the cooperation of the base plate 1, support frame 11, and base frame 12, facilitates the support of the storage box 13, facilitates the storage of the sensor 71, facilitates the support of the motor 5 by the cooperation of the outer frame 52 and support column 51, facilitates the support of the rotating rod 83 by the cooperation of the support ring 8, side block 81, and support frame 82, facilitates the support of the rack 4 by the base rod 42, and facilitates the support of the rack 4 by the sliding connection of the sliding rod 3 and the sliding hole. The connecting plate 7 is guided and limited. The side rod 32, in cooperation with the first connecting block 31, facilitates support for the sliding rod 3. The support rod 65 facilitates support for the main extrusion block 64. The connecting rod 6 facilitates support for the auxiliary extrusion block 61. The guide rod 62 facilitates guidance and limitation for the auxiliary extrusion block 61. The motor 5, when started, drives the rotating rod 83 to rotate. When the rotating rod 83 rotates, it drives the rack 4 to move. When the rack 4 moves, it drives the connecting plate 7 to move. When the connecting plate 7 moves, it drives... When sensor 71 moves, it can be moved into storage box 13 for storage. When connecting plate 7 moves, it can drive main extrusion block 64 to move, thus moving main extrusion block 64 away from auxiliary extrusion block 61. At this time, spring 63 extends and retracts, thereby driving guide rod 62 to slide on storage box 13. When guide rod 62 slides, it can drive protective mesh plate 2 to move, thereby closing storage box 13. This facilitates the storage and protection of sensor 71, allowing sensor 71 to be stored and protected when not in use, preventing sensor 71 from being damaged by impact. The limiting ring 91 is slidably connected to the limiting ring 91, which facilitates the guiding and limiting of the adjusting plate 72 and the sensor 71. The connecting column 93 facilitates the support of the adjusting plate 72. Since the compensating rod 73 and the sensor 71 are made of the same metal material, under the condition that the coefficient of thermal expansion and height are the same, the thermal expansion and contraction increment of the sensor 71 and the compensating rod 73 are the same, but their directions are exactly opposite. That is, when the temperature rises, the compensating rod 73 extends backward and the sensor 71 extends forward, and vice versa. This can play a mutual cancellation role, thereby minimizing temperature drift.
