Description

Technical Field

[0001] The utility model relates to the technical field of cold chain transportation, in particular to a temperature monitoring device for cold chain transportation of dairy products. Background Art

[0002] Fresh milk squeezed out by dairy farmers is a fresh product. Usually, if it is stored at a temperature above 30℃ for more than 5 hours, the fresh milk will deteriorate and fail to meet the national purchasing standards. In the hot summer season, if fresh milk cannot be delivered to milk processing companies or milk stations in time, once the milk deteriorates, dairy farmers will suffer great economic losses, waste milk resources, and restrict the sustainable development of animal husbandry. Therefore, when transporting fresh milk, staff will use storage boxes with both insulation and monitoring functions to transport the fresh milk.

[0003] Common temperature monitoring devices used for cold chain transportation of dairy products mainly include an insulated box and a temperature and humidity sensor installed inside the box. The installation position of the temperature and humidity sensor is relatively important. If the sensor is too close to the edge of the box during installation, and there is a large temperature difference between the edge of the box and the center of the box, the measurement result will be affected by the local temperature gradient rather than the true average temperature of the target area. Therefore, the sensor unit of the traditional monitoring device is installed on the side of the box that is biased towards the center. However, the disadvantage of this setting is that since the sensor is fixed to the box, when transporting some relatively loose products, the products in the box will not only collide with the inner wall of the box, but also with the exposed sensor unit, which will then damage the internal structure of the sensor unit and affect the stability and life of the monitoring device. Summary of the invention

[0004] In view of the above problems, the utility model proposes a dairy cold chain transportation temperature monitoring device to solve the shortcomings of the existing monitoring device that when transporting some relatively loose products, the products in the box will not only collide with the inner wall of the box, but also collide with the exposed sensor unit, thereby destroying the internal structure of the sensor unit and affecting the stability and life of the monitoring device.

The cylindrical pin is electrically connected to the display through a wire. A temperature and humidity sensor is provided at the end of the cylindrical pin away from the wire. The cylindrical pin passes through a positioning sleeve and extends into the insulation inner box. A positioning component is provided on the outside of the positioning sleeve for limiting the cylindrical pin from sliding along the inner wall of the temperature and humidity sensor.

[0008] A further improvement is that the cylindrical pin passes through the positioning sleeve and is slidably connected to the positioning sleeve, both ends of the cylindrical pin extend outside the positioning sleeve, and at least one strip edge is provided on the outside of the cylindrical pin, the strip edge is parallel to the axis of the positioning groove, and the strip edge is slidably connected to the guide groove opened on the inner side of the positioning sleeve.

[0009] Further improvement is that: the positioning assembly includes a bolt plate and a positioning bolt, one end of the bolt plate is fixedly connected to the positioning sleeve, the positioning bolt is installed at the other end of the bolt plate, the positioning bolt passes through the bolt plate and is threadedly connected to the positioning groove opened on the outside of the cylindrical pin, and the outside of the cylindrical pin has multiple positioning grooves, and each positioning groove is evenly arranged in the direction of the length of the cylindrical pin.

[0012] A further improvement is that: an interlayer is provided between the inner side wall of the outer box body and the outer side wall of the heat-insulating inner box, and the interlayer is filled with a heat-insulating layer.

[0013] The beneficial effect of the utility model is that after the locking of the cylindrical pin by the positioning component is released, the position of the cylindrical pin is adjusted, and then the test area of ​​the temperature and humidity sensor is changed, thereby improving the accuracy of temperature monitoring.

[0014] At the same time, the temperature and humidity sensor can be placed in the positioning sleeve.

[0024] About the temperature monitoring module: The temperature monitoring module includes a display 7 and a cylindrical pin 13. The display 7 is detachably connected to the outside of the outer box 1. The cylindrical pin 13 is electrically connected to the display 7 through a wire 10. A temperature and humidity sensor 9 is provided at one end of the cylindrical pin 13 away from the wire 10. The cylindrical pin 13 passes through the positioning sleeve 8 and extends into the heat preservation inner box 5. A positioning component is provided on the outside of the positioning sleeve 8 for limiting the cylindrical pin 13 from sliding along the inner wall of the temperature and humidity sensor 9. The display 7 monitors the temperature and humidity changes in the heat preservation inner box 5 through the temperature and humidity sensor 9 on the cylindrical pin 13 and displays them. After the positioning component is released from locking the cylindrical pin 13, the position of the temperature and humidity sensor 9 on the cylindrical pin 13 can be adjusted, and then the test area of ​​the temperature and humidity sensor 9 can be changed to improve the accuracy of temperature monitoring. At the same time, the temperature and humidity sensor 9 can also be put into the positioning sleeve 8, so that when the entire monitoring device is carried, the objects in the heat preservation inner box 5 will not directly collide with the temperature and humidity sensor 9, thereby improving the service life of the sensing unit of the monitoring module.

[0025] Specifically, the cylindrical pin 13 passes through the positioning sleeve 8 and is slidably connected with the positioning sleeve 8. Both ends of the cylindrical pin 13 extend outside the positioning sleeve 8. At least one strip rib 18 is provided on the outside of the cylindrical pin 13. The strip rib 18 is parallel to the axis of the positioning groove 17. The strip rib 18 is slidably connected with the guide groove 19 provided on the inner side of the positioning sleeve 8. When the cylindrical pin 13 is inserted into the positioning sleeve 8, the strip rib 18 on the outside of the cylindrical pin 13 will also be inserted into the guide groove 19 provided on the inner side of the positioning sleeve 8. The cylindrical pin 13 slides along the inner wall of the temperature and humidity sensor 9, and the strip rib 18 slides along the guide groove 19. The guide groove 19 cooperates with the strip rib 18 to limit the rotation of the cylindrical pin 13 and improve the stability of the cylindrical pin 13 when sliding.

[0026] About the positioning assembly: The positioning assembly includes a bolt plate 15 and a positioning bolt 16. One end of the bolt plate 15 is fixedly connected to the positioning sleeve 8, and the positioning bolt 16 is installed at the other end of the bolt plate 15. The positioning bolt 16 passes through the bolt plate 15 and is threadedly connected to the positioning groove 17 opened on the outside of the cylindrical pin 13. The outside of the cylindrical pin 13 has multiple positioning grooves 17, and each positioning groove 17 is evenly arranged in the direction of the length of the cylindrical pin 13. The positioning assembly adopts a bolt connection method to limit the cylindrical pin 13 from sliding along the inner wall of the positioning sleeve 8. Turn the positioning bolt 16 to pull the positioning bolt 16 out of the positioning groove 17 on the outside of the cylindrical pin 13. The cylindrical pin 13 can continue to slide along the inner wall of the positioning sleeve 8 to adjust the position of the temperature and humidity sensor 9. After the adjustment is completed, turn the positioning bolt 16 again and screw the positioning bolt 16 into the corresponding positioning groove 17 to complete the re-fixation of the cylindrical pin 13.

[0027] Regarding the connection and fixation between the display 7 and the outer box 1: screws 11 are installed at the corners of the display 7, and the screws 11 pass through the display 7 and are threadedly connected to the bolt holes opened on the outside of the outer box 1.

In addition, a bracket 12 is provided at the lower end of the display 7, and the bracket 12 is fixedly connected to the outer box 1. A groove is provided at the upper end of the bracket 12, and the lower end of the display 7 is inserted into the groove. When the display 7 is fixed by the screws 11, the lower end of the display 7 is stuck in the groove opened at the upper end of the bracket 12, and the bracket 12 can support the display 7 and improve the impact resistance of the display 7.

[0028] The box door 2 at the upper end of the thermal insulation inner box 5 adopts a double-opening design. Specifically, the box door 2 includes two door panels.
