Description

Technical Field

[0001] The utility model application relates to the technical field of measuring probes, in particular to a temperature, humidity and air pressure integrated measuring probe. Background Art

[0002] Integrated temperature, humidity and air pressure measuring probes are generally used for meteorological data detection within the environment. For example, meteorological monitoring refers to the activities of meteorological monitoring agencies to conduct overall monitoring and early warning of meteorological environmental conditions through meteorological monitoring systems. Integrated temperature, humidity and air pressure measuring probes are generally used for temperature, humidity and atmospheric pressure measurement, display and recording.

[0003] Most of the existing integrated temperature, humidity and pressure measurement probes integrate the temperature sensor, humidity sensor and pressure sensor into the probe, and transmit the detected data through a data cable. When installing, most of the current probes are directly fixed to the detector connecting column through a flange or threaded screw. However, flange fixation requires tightening a large number of bolts, and directly fixing through threaded screws can easily cause the data cable to become entangled and twisted. Summary of the Invention

[0007] Furthermore, an insertion rod is fixed to one end of the probe support rod away from the probe body, and a positioning sleeve is sleeved on the insertion rod, and the positioning sleeve is fixed to the inner wall of the probe shell away from the probe body end.

[0008] Furthermore, the fixing sleeve is fixed with a limiting ring plate near the outer surface of the probe support rod end, and the outer ring diameter of the limiting ring plate is equal to the outer ring diameter of the fixed spiral tube, and the length between the limiting ring plate and the outer end of the limiting plate is equal to the length of the fixed spiral tube.

[0009] Furthermore, the outer surface of the limiting plate and the inner wall of the fixed spiral tube are provided with mutually matching threads, and the outer ring diameter of the limiting plate is larger than the outer ring diameter of the fixed sleeve.

[0010] Furthermore, a dustproof net is provided on the sliding sleeve inside the probe housing inside the air vent window, and one end of the dustproof net abuts on the probe support rod, and the other end abuts on a clamping plate, and the clamping plate is fixed on the inner wall of the probe housing.

[0011] Furthermore, the outer diameter of the dustproof net is equal to the inner diameter of the probe housing, the thickness of the cardboard is equal to the thickness of the dustproof net, and the humidity sensor is located in the middle of the dustproof net.

[0021] Reference Figure 1 、 Figure 2 and Figure 3 A temperature, humidity and air pressure integrated measuring probe includes a probe body 1 and a probe support rod 2. The probe support rod 2 is provided with a temperature sensor 3, a humidity sensor 4 and an air pressure sensor 5 in sequence. A fixed sleeve 6 is provided on the outer side of the probe body 1. A limit plate 9 is fixed on the end of the fixed sleeve 6 away from the probe support rod 2. A fixed screw 10 is provided on the outer side of the fixed sleeve 6 and the limit plate 9, and the internal rotation sleeve of the fixed screw 10 is provided on the outer side of the fixed sleeve 6. The internal thread of the fixed screw 10 is connected to the limit plate 9. The outer surface of the limit plate 9 and the inner wall of the fixed screw 10 are provided with mutually matching threads. The outer ring diameter is larger than the outer ring diameter of the fixed sleeve 6. A limiting ring plate 11 is fixed to the outer surface of the fixed sleeve 6 near the end of the probe support rod 2, and the outer ring diameter of the limiting ring plate 11 is equal to the outer ring diameter of the fixed screw 10. The length between the limiting ring plate 11 and the outer end of the limiting plate 9 is equal to the length of the fixed screw 10. A probe shell 8 is sleeved on the outside of the probe support rod 2, and a connecting screw 7 is threadedly sleeved on one end of the probe shell 8 close to the probe body 1. The connecting screw 7 is fixed on the side of the fixed sleeve 6. A ventilation window 12 is opened inside the probe shell 8 outside the temperature sensor 3, the humidity sensor 4 and the pressure sensor 5.

[0022] Specifically, when the probe body 1 needs to be installed, align the probe body 1 and put it on the detector connecting column, pass the data line through the connecting column, and then rotate the fixing screw 10 so that the fixing screw 10 is screwed until the thread is fixedly connected to the outside of the detector connecting column. The probe body 1 can be fixed to the detector. After ensuring that the temperature sensor 3, humidity sensor 4 and pressure sensor 5 can operate stably, the probe shell 8 is put on the outside of the probe support rod 2 and screwed on the connecting screw 7 to fix it.

[0023] As an optimization solution, Figure 2 and Figure 3 As shown, an insertion rod 16 is fixed to the end of the probe support rod 2 away from the probe body 1, and a positioning sleeve 15 is sleeved on the insertion rod 16. The positioning sleeve 15 is fixed on the inner wall of the probe shell 8 away from the probe body 1. A dustproof net 13 is slidingly sleeved inside the probe shell 8 inside the air vent 12. The outer ring diameter of the dustproof net 13 is equal to the inner ring diameter of the probe shell 8, and the thickness of the card plate 14 is equal to the thickness of the dustproof net 13. The humidity sensor 4 is located in the middle of the dustproof net 13, and one end of the dustproof net 13 abuts on the probe support rod 2, and the other end abuts on the card plate 14. The card plate 14 is fixed on the inner wall of the probe shell 8.

[0024] Specifically, when the probe shell 8 is put on the probe support rod 2, first put the dustproof net 13 on the outside of the temperature sensor 3, humidity sensor 4 and pressure sensor 5, and abut against the probe support rod 2, then put the probe shell 8 on the dustproof net 13, and make the clamping plate 14 abut against the side of the dustproof net 13 to fix the dustproof net 13. When the probe shell 8 is put on the probe support rod 2, it drives the positioning sleeve 15 to be put on the insertion rod 16, which can increase the firmness of the connection of the probe shell 8.
