Description

Technical Field

[0001] This utility model relates to the field of temperature and humidity detectors, specifically to a portable temperature and humidity detector. Background Technology

[0002] The patent background technology of a portable temperature and humidity detector is crucial in fields such as industrial production, business management, home monitoring, and scientific research experiments, where real-time and accurate detection of temperature and humidity is essential. Portable temperature and humidity detectors (also known as handheld temperature and humidity detectors) are commonly used in various fields due to their small size, light weight, ease of operation, and rapid data acquisition. They can efficiently complete detection when the detection location is within the operator's arm's reach.

[0003] However, in practical applications, the location to be detected in many scenarios is only 20 to 30 cm higher than the operator's arm extension limit. This slight height difference makes traditional detection instruments inconvenient to use.

[0004] Taking industrial production scenarios as an example, electronic component manufacturing workshops need to regularly monitor the temperature and humidity near electronic components on the upper edge of shelves. These shelves are slightly higher than the operator's arm limit, with the target position 20-30cm above the reachable area. Operators cannot directly deliver the testing end; due to the small height difference, a ladder is unnecessary, and they must either stand on tiptoe, stretch their body, or use small objects to elevate it. Standing on tiptoe or stretching can easily lead to imbalance, causing inaccurate testing data and potentially causing collisions with equipment or damage to components. Finding objects to elevate the device is time-consuming and inefficient, and even after elevating it, careful posture control is still required, significantly reducing the convenience and safety of the testing process.

[0005] To address this issue, another portable temperature and humidity detector is provided. Utility Model Content

[0006] The purpose of this invention is to provide a portable temperature and humidity detector to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable temperature and humidity detector, comprising a detector body, a main shell fixedly mounted on the outer surface of the detector body, a mounting hole through the upper surface of the main shell, the main shell being L-shaped, and an auxiliary shell mounted on the rear side of the main shell, two telescopic rods fixedly mounted between the auxiliary shell and the main shell, a detection line inserted into the upper surface of the detector body, the detection line passing through the mounting hole, and a probe electrically connected to one end of the detection line away from the detector body, the probe being detachably mounted on the rear surface of the auxiliary shell.

[0008] Preferably, the lower surface of the main shell and the upper surface of the auxiliary shell are respectively screwed to the upper and lower ends of the telescopic rod.

[0009] Preferably, elastic clip A and elastic clip B are fixedly installed on the rear surface of the auxiliary shell, the middle part of the probe is clamped and installed in elastic clip A, and the lower end of the probe is clamped and installed in elastic clip B.

[0010] Preferably, the upper and rear surfaces of the auxiliary shell are respectively provided with an arc-shaped hole and a through hole, and the detection line passes through the arc-shaped hole and the through hole.

[0011] Preferably, two L-shaped ribs are fixedly installed on the rear surface of the main shell, and two baffles are fixedly installed on the front surface of the auxiliary shell, with the baffles slidably installed within the corresponding L-shaped ribs.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by setting an auxiliary shell on the rear side of the L-shaped main shell and installing two metal telescopic rods between the main shell and the auxiliary shell, which are fixed by screws and are maintainable and replaceable, can effectively compensate for the slight height difference of 20-30cm between the position to be tested and the operator's arm extension limit. It eliminates the need for the operator to stand on tiptoe or use objects to raise the position, thus avoiding the risk of deviation in test data and collision with equipment or damage to components caused by unstable posture. It also saves time spent finding objects to raise the position, improving the convenience and safety of the test.

[0014] By fixing elastic clips A and B to the rear surface of the auxiliary shell, the probe head is clamped and fixed at two points, which effectively avoids the probe head being pulled by the detection wire made of spring cable when the auxiliary shell is moved up to adjust the detection position, thus avoiding affecting the stability.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution:

[0023] A portable temperature and humidity detector includes a main body 1, a main shell 2 fixedly mounted on the outer surface of the main body 1, a mounting hole 21 through the upper surface of the main shell 2, the main shell 2 being L-shaped, and an auxiliary shell 3 mounted on the rear side of the main shell 2. Two metal (iron or stainless steel) telescopic rods 4 are fixedly mounted between the auxiliary shell 3 and the main shell 2. The telescopic rods 4 have a telescopic stroke difference of 20 to 30 centimeters and possess sufficient strength and telescopic flexibility. A detection line 11 is inserted and mounted on the upper surface of the main body 1. The detection line 11 is a spring cable that passes through the mounting hole 21, and a probe 12 is electrically connected to the end of the detection line 11 away from the main body 1. The probe 12 is detachably mounted on the rear surface of the auxiliary shell 3.

[0024] When detecting heights beyond the limit detection distance of the arm, the 20-30cm height difference can be compensated by stretching the telescopic rod 4, allowing the probe head 12 to move upward and be delivered to the target detection position. This solves the problems of "unstable extension on tiptoe and time-consuming search for auxiliary tools", making it convenient and quick to use.

[0025] It should be noted that screws 41 are screwed to the lower surface of the main shell 2 and the upper surface of the auxiliary shell 3, respectively, and the upper and lower ends of the telescopic rod 4. After removing the screws 41, the telescopic rod 4 can be maintained and replaced.

[0026] Combination Figure 2 As shown, elastic clips A33 and B34 are fixedly installed on the rear surface of the auxiliary shell 3. The middle part of the probe 12 is clamped and installed in the elastic clip A33, and the lower end of the probe 12 is clamped and installed in the elastic clip B34. The elastic clips A33 and B34 fix the probe 12 stably on the auxiliary shell 3 by clamping at two points. When the auxiliary shell 3 is moved up to adjust the detection position of the probe 12, the stability of the probe 12 is not affected by the pull of the detection line 11.

[0027] To ensure the stability of the instrument held by the operator during testing, anti-slip texture 23 is also provided on the outer surface of the main shell 2.

[0028] In addition, to facilitate the storage of the detection line 11 inside the auxiliary casing 3 for easy portability, combined with Figure 2As shown, an arc-shaped hole 31 and a through hole 32 are respectively opened on the upper and rear surfaces of the auxiliary shell 3. After the two ends of the detection line 11 are passed through the arc-shaped hole 31 and the through hole 32 respectively, they are electrically connected to the main body 1 of the temperature and humidity detector and the probe 12. This allows most of the detection line 11 to be stored inside the auxiliary shell 3, which not only makes the overall structure of the instrument more regular and eliminates the need to organize the lines separately when carrying it, but also prevents the detection line 11 from getting tangled and knotted, thus ensuring the stability of the line signal transmission.

[0029] Finally, during normal use or transport of the instrument, to prevent the auxiliary shell 3 from shifting laterally or backward and causing accidental bending of the telescopic rod 4, two L-shaped ribs 22 need to be fixedly installed on the rear surface of the main shell 2, and two retaining ribs 35 need to be fixedly installed on the front surface of the auxiliary shell 3. Guided by the telescopic rod 4, the auxiliary shell 3 naturally moves vertically downward. After its lower surface fits against the upper rear surface of the main shell 2, the retaining ribs 35 slide within the corresponding L-shaped ribs 22, firmly restricting the lateral (sideways) and longitudinal (backward) movement of the auxiliary shell 3. At this point, only the vertical degree of freedom of extension and retraction is retained. Through the cooperation of the retaining ribs 35 and the L-shaped ribs 22, external impacts during transport or placement can be effectively resisted, preventing the auxiliary shell 3 from shifting and generating lateral forces on the telescopic rod 4, avoiding bending, deformation, or loosening of the telescopic rod 4, ensuring the structural integrity and service life of the telescopic rod 4, and guaranteeing the reliability of the instrument during long-term use.
