Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-7 As shown, the utility model provides a testing device for a sensor, comprising a workbench 1, a support table 11 is fixedly installed on the top of the workbench 1, a tooth plate 12 is slidably provided on the top of the support table 11, two symmetrically distributed placement plates 3 are fixedly installed on the top of the tooth plate 12, a placement box 31 is provided on the top of the placement plate 3, a U-shaped fixed block 13 is fixedly installed on the bottom end of the workbench 1, a fixed block 14 is fixedly installed on one side of the inner wall of the U-shaped fixed block 13, a rotating shaft 15 is rotatably installed in the middle of the fixed block 14, the rotating shaft 15 rotatably runs through the workbench 1 and the support table 11, a half-face gear 16 corresponding to the tooth plate 12 is fixedly installed on the top of the rotating shaft 15, and a gear 17 is fixedly installed on the outside of the rotating shaft 15 and located in the U-shaped fixed block 13;

[0021] A fixing seat 2 is fixedly installed on the side of the inner wall of the U-shaped fixing block 13 away from the fixing block 1 14, a rotating shaft 21 is rotatably penetrated through the middle of the fixing seat 2, and a half-face gear 22 corresponding to the gear 17 is fixedly installed on the outside of the rotating shaft 21. The rotating shaft 21 rotates and penetrates the workbench 1, and a detection device 10 is fixedly installed on the upper surface of the workbench 1. A motor 23 is fixedly installed on the upper surface of the inner wall of the U-shaped fixing block 13, and the driving end of the motor 23 is fixedly installed on the end of the rotating shaft 21. By setting the motor 23, when the motor 23 is started, the rotating shaft 21 is driven to rotate, thereby driving the half-face gear 22 to rotate.

[0022] A horizontal plate 32 is fixedly installed at the top edge of the placement plate 3, and a fixing plate 33 is fixedly installed at the edge of the side of the top of the placement plate 3 away from the horizontal plate 32. A plurality of evenly distributed springs 34 are fixedly installed on one side of the fixing plate 33, and a clamping plate 35 is fixedly installed on the side of the spring 34 away from the fixing plate 33. A handle 36 is fixedly installed at the top of the clamping plate 35, and a plurality of evenly distributed anti-slip strips 37 are fixedly installed on both sides of the handle 36. By setting the handle 36, it is convenient to move the clamping plate 35, so that the clamping plate 35 is separated from the placement box 31, and the placement box 31 is not fixed. At the same time, the anti-slip strips 37 increase the friction between the hand and the handle 36. A vertical plate 7 is fixedly installed on one side of the top of the placement plate 3. By setting the vertical plate 7, it is more convenient to place the placement box 31 and the sensor on the placement plate 3.

[0023] Two symmetrically distributed trapezoidal blocks 4 are fixedly installed at the bottom end of the clamping plate 35, and a trapezoidal groove 41 corresponding to the trapezoidal block 4 is opened at the top of the placing plate 3. The trapezoidal block 4 is slidably engaged in the trapezoidal groove 41. By setting the trapezoidal block 4 and the trapezoidal groove 41, the clamping plate 35 is more stable when moving.

[0024] Telescopic rods 5 corresponding to springs 34 are fixedly installed between the fixing plate 33 and the clamping plate 35. Each spring 34 is located outside the telescopic rod 5. By providing the telescopic rod 5, the spring 34 is more stable when being telescoped.

[0025] The two side edges of the clamping plate 35 are fixedly installed with fixing blocks 2 6, and the middle part of each fixing block 2 6 is penetrated by a limiting groove 1 61, and the top of the placing plate 3 is provided with two symmetrically distributed limiting grooves 2 62, and the top of the placing plate 3 is fixedly installed with a supporting plate 63 at the position corresponding to the limiting groove 2 62. The top of the supporting plate 63 is provided with a clamping groove 64, and the internal movement of the clamping groove 64 is provided with a handle 2 65, and the bottom end of the handle 2 65 is fixedly installed with a limiting column 66. By setting the handle 2 65 and the limiting column 66, when the trapezoidal block 4 moves in the trapezoidal groove 41 to one end close to the supporting plate 63, the limiting groove 1 61, the limiting groove 2 62 and the limiting column 66 correspond to each other, and then the handle 2 65 is taken out of the clamping groove 64, and the limiting column 66 is clamped into the limiting groove 1 61 and the limiting groove 2 62, so that the clamping plate 35 is fixed, the spring 34 will not rebound, and it is more convenient to install the placing box 31 and the sensor on the placing plate 3.

[0026] Working principle: In actual use, the sensor is first placed in the placement box 31, and then the entire placement box 31 and the sensor in the placement box 31 are placed on the placement plate 3. When the sensor needs to be replaced, the placement box 31 can be directly taken down. For specific operations, the rotation shaft 21 is rotated to drive the half-face gear 22 to rotate. When the half-face gear 22 is engaged with the gear 17, the rotation shaft 15 is driven to rotate, and the rotation shaft 15 drives the half-face gear 16 to rotate. When the half-face gear 16 is engaged with one side of the tooth plate 12, the corresponding tooth plate 12 and the placement plate 3 are driven to move. Then, when the half-face gear 16 is engaged with the edge of the tooth plate 12, the placement plate 3, the placement box 31 and the sensor in the placement box 31 are located in the detection device 10 for detection, and at the same time, the half-face gear 22 is engaged with the gear 1 7 is not engaged, the rotating shaft 21 and the half-face gear 16 stop rotating, when the half-face gear 22 is engaged with the gear 17 again, the rotating shaft 15 drives the half-face gear 16 to rotate, and the half-face gear 16 is engaged with the other side of the toothed plate 12, driving the toothed plate 12 and the placement plate 3 to move in the opposite direction, so that the other placement plate 3 and the placement box 31 and the sensor in the placement box 31 are located in the detection device 10 for detection, and at the same time, the half-face gear 22 is not engaged with the gear 17, and the half-face gear 16 stops rotating. Every time the placement plate 3 and the placement box 31 and the sensor in the placement box 31 are located in the detection device 10, at the same time, the placement box 31 on the placement plate 3 at the other end that has been detected is replaced with the undetected sensor, so that the sensor can be detected and replaced continuously and uninterruptedly.

[0027] When the clamping plate 35 moves toward the direction of the fixed plate 33, the spring 34 contracts, so that the clamping plate 35 does not clamp the placement box 31, thereby facilitating the removal of the placement box 31; then, when the limiting column 66 is not stuck in the corresponding limiting groove 1 61 and limiting groove 2 62, the spring 34 has no resistance and directly drives the clamping plate 35 to rebound in the direction of the placement box 31, and then cooperates with the cross plate 32 to fix the placement box 31 on the placement plate 3.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
