[0025] Example:

[0026] As attached Figure 1 To Attachment Figure 4 As shown:

[0027] A batch automatic calibration device for temperature and humidity sensors, comprising a chassis 1, first electric push rods 2 are symmetrically installed on the outer walls of both sides of the chassis 1, a pair of mounting frames 3 are installed on the top end faces of the extended ends of the first electric push rods 2, a pair of the mounting frames 3 are provided with a rotating shaft 4 at the center position of the opposite side, a pair of the rotating shafts 4 are provided with a rotating disk 5 on the surface, a pair of the rotating shafts 4 are fixedly installed with a first gear 6 on the end faces of the side away from the rotating disk 5, a pair of the edges of the opposite side of the rotating disk 5 are symmetrically connected with two connecting rods 7, a pair of the surfaces of the connecting rods 7 close to the rotating disk 5 on both sides are provided with a second gear 8, the surface of the rotating disk 5 is located between the first gear 6 and the second gear 8 and is also rotatably connected with a transmission gear 9, the transmission gear 9 is meshed with the first gear 6 and the second gear 8, a pair of the connecting rods 7 are installed with a sensor fixing assembly, the sensor fixing assembly includes a hollow base 10 connected to the connecting rod 7, a plurality of conical mounting seats 16 are penetrated on the hollow base 10, through the first electric push rod 2, the rotating disk 5, the transmission gear 9, the first gear 6, the second gear 8, the connecting rod The use of the sensor fixing assembly 7 and the sensor fixing assembly realizes that when one group of temperature and humidity sensors is being calibrated, the operator can disassemble and install another group of temperature and humidity sensors on another sensor fixing assembly, and after the calibration of one group of temperature and humidity sensors is completed, the first electric push rod 2 is started to extend the extended end of the first electric push rod 2, so that the calibrated group of temperature and humidity sensors are separated from the calibration position, and the turntable 5 is rotated to make the other group of temperature and humidity sensors enter the calibration position, thereby saving the standby time of the calibration device when disassembling and installing the temperature and humidity sensors, thereby improving the efficiency of the device. In order to improve the calibration efficiency, a conical seat sleeve 20 is provided at the top of the chassis 1 at the corresponding position of each conical mounting seat 16. The conical seat sleeve 20 passes through the box body at the top of the chassis 1. The conical mounting seat 16 is adapted to the size of the conical seat sleeve 20. By using the conical mounting seat 16 and the conical seat sleeve 20 in coordination, it is possible to retract the extended end of the first electric push rod 2 after a group of temperature and humidity sensors to be tested enter the calibration position, so that the conical mounting seat 16 and the conical seat sleeve 20 are in contact with each other, thereby facilitating the temperature and humidity sensor probe to be tested to be extended into the chassis 1 for calibration.

[0028] Among them, the first rack 11 and the second rack 12 are symmetrically slidably connected on both sides of the conical mounting seat 16 inside the hollow base 10, and two slide grooves 13 are symmetrically arranged on the top of the hollow base 10. The top of the hollow base 10 is located on both sides of the conical mounting seat 16 and multiple pairs of first clamping blocks 14 and second clamping blocks 15 are evenly installed. The first clamping block 14 and the second clamping block 15 are respectively slidably connected to different slide grooves 13, and the first clamping block 14 and the second clamping block 15 are respectively fixedly connected to the first rack 11 and the second rack 12. The multiple conical mounting seats 16 are located inside the hollow base 10 and the outer side is set with a third gear 17. The third gear 17 is meshed and connected with the first rack 11 and the second rack 12. The rack 11, the second rack 12 and the third gear 17 are used in coordination. When the second rack 12 is displaced to one side, the third gear 17 is driven to rotate, and the first rack 11 meshing with it is displaced in the opposite direction of the second rack 12, thereby driving the first block 14 and the second block 15 on the first rack 11 and the second rack 12 to displace, thereby fixing the temperature and humidity sensor installed on the conical mounting seat 16, preventing the temperature and humidity sensor from falling when the turntable 5 drives the sensor fixing assembly to move, or affecting the calibration result due to the loosening of the engagement position of the temperature and humidity sensor and the conical mounting seat 16, and utilizing the characteristics of synchronous displacement of the first block 14 and the second block 15 on the first rack 11 and the second rack 12, saving the time for disassembling and assembling the temperature and humidity sensor, thereby improving the working efficiency of the device.

[0029] Among them, a motor 18 is fixedly installed on one side of the mounting frame 3 away from the turntable 5, and the output end of the motor 18 passes through the mounting frame 3 and is connected to the turntable 5. Through the coordinated use of the motor 18, the turntable 5 and the mounting frame 3, the turntable 5 is driven to rotate by the motor 18, thereby reducing the work intensity of the operator.

[0030] Among them, the first gear 6 and the second gear 8 are of the same size. When the turntable 5 is rotating, since the first gear 6 is meshed with the transmission gear 9, and the transmission gear 9 is meshed with the second gear 8, the second gear 8 and the first gear 6 rotate synchronously. The first gear 6 and the second gear 8 are of the same size, so the connecting rod 7 installed on the second gear 8 and the sensor fixing assembly on the connecting rod 7 are always kept parallel to the top plane of the chassis 1, thereby ensuring that when the turntable 5 drives the sensor fixing assembly to reach the top of the conical seat sleeve 20, the conical mounting seat 16 remains in a vertical state, thereby facilitating the subsequent fitting of the conical mounting seat 16 and the conical seat sleeve 20, and then the subsequent calibration work can be carried out.

[0031] Among them, a rubber layer is provided on the inner side of the conical mounting seat 16. By installing the rubber layer on the inner side of the conical mounting seat 16, the portion where the conical mounting seat 16 and the humidity sensor meet is buffered by rubber material to prevent damage to the temperature and humidity sensor during disassembly and assembly, and the addition of the rubber layer can make the contact portion between the conical mounting seat 16 and the temperature and humidity sensor more sealed, thereby ensuring the accuracy of the calibration result. Rubber pads are provided on the opposite side surfaces of each pair of the first clamping block 14 and the second clamping block 15. By installing rubber pads on the opposite sides of the first clamping block 14 and the second clamping block 15, the first clamping block 14 and the second clamping block 15 will not cause damage to the temperature and humidity sensor when clamping the temperature and humidity sensor. The conical mounting seat 16 is located on the outer side of the bottom end of the hollow base 10 and is provided with a sealing ring 19. By installing the sealing ring 19 on the outer side of the conical mounting seat 16, the conical mounting seat 16 and the conical seat sleeve 20 can be more closely fitted, thereby improving the sealing effect, thereby ensuring the accuracy of the calibration data.

[0032] Among them, the conical seat sleeve 20 is located on the top surface of the chassis 1 and is equipped with a rubber ring 21. By installing the rubber ring 21 on the top surface of the chassis 1, the bottom of the hollow base 10 can be tightly fitted with the top of the conical seat sleeve 20, thereby improving the air tightness and ensuring the accuracy of the calibration data.

[0033] Among them, a second electric push rod 22 is installed on the inner wall of the hollow base 10 near the turntable 5, and the extended end of the second electric push rod 22 is connected to the end face of one side of the second rack 12. Through the coordinated use of the second electric push rod 22 and the second rack 12, the second rack 12 can be moved by driving the second electric push rod 22 to extend and retract, thereby controlling the displacement of the first block 14 and the second block 15, thereby realizing the fixing and loosening of the temperature and humidity sensor, which is convenient for the operator to disassemble and assemble the temperature and humidity sensor and reduces the labor intensity of the operator.

[0034] The specific usage and function of this embodiment are as follows:

[0035] Before the utility model is installed and used, the staff needs to check the internal components or structures of the device. After the inspection is correct, it can be used normally. After the device is powered on, the second electric push rod 22 is driven to extend the extended end to increase the distance between the first clamping block 14 and the second clamping block 15, and then each temperature and humidity sensor is inserted into each conical mounting seat 16 in sequence at a vertical angle, and then the extended end of the second electric push rod 22 is controlled to retract, so that the first clamping block 14 and the second clamping block 15 clamp and fix the temperature and humidity sensor, and then the motor 18 is driven to rotate the turntable 5. When the position of the conical mounting seat 16 corresponds to the position of the conical seat sleeve 20, the motor 18 is stopped, and the first electric push rod 2 is controlled to retract, so that the conical mounting seat 16 and the conical seat sleeve 20 are in a fixed position. The conical mounting seat 16 is combined with the conical seat sleeve 20, and then the calibration operation can be performed. At this time, the second group of temperature and humidity sensors to be measured is installed on another sensor fixing assembly. When a group of temperature and humidity sensors is calibrated, the extending end of the first electric push rod 2 is controlled to extend so that the calibrated group of temperature and humidity sensors are separated from the conical seat sleeve 20, and then the turntable 5 and the first electric push rod 2 are driven according to the above steps to make the temperature and humidity sensors to be measured enter the calibration position. Repeat the above operations to perform batch calibration of the temperature and humidity sensors. The above steps can realize the rapid disassembly and assembly of the temperature and humidity sensors, reduce the standby time of the calibration device when replacing the temperature and humidity sensors to be measured, and improve the calibration efficiency.

[0036] The implementation modes of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
