Description

Technical Field

[0001] The utility model relates to the field of infrared temperature measurement, and particularly relates to an infrared temperature measurement device. Background Technique

[0002] The working principle of an infrared thermometer gun is as follows:

[0003] All objects radiate infrared rays, and the radiation intensity is related to the temperature of the object; the optical system inside the infrared thermometer gun collects the infrared rays emitted by the object to be measured; the detector converts the received infrared rays into electrical signals, and then goes through a series of processes such as signal processing and amplification; finally, the temperature value is displayed through the display device on the thermometer gun, thus realizing non-contact measurement of the object's temperature; simply put, it is to utilize the characteristic that objects radiate infrared rays and determine the temperature of the object by receiving and processing infrared rays; for example, when we use an infrared thermometer gun to measure the human body temperature, the thermometer gun receives the infrared rays radiated by the human body and converts and processes them to obtain the body temperature value;

[0004] When the distance between the infrared thermometer gun and the object to be measured is relatively far, a reading lower than the actual temperature will appear, because the far distance will cause a reduction in the amount of infrared radiation received, thus affecting the measurement accuracy; when the distance between the infrared thermometer gun and the object to be measured is relatively close, the local temperature of the object to be measured will be affected by the temperature of the thermometer gun itself due to the too close distance, resulting in inaccurate measurement results. Content of the Utility Model

[0005] The purpose of the utility model is to provide an infrared temperature measurement device to solve the defects mentioned in the above background technique.

[0006] To achieve the above purpose, an infrared temperature measurement device is provided, including an infrared thermometer gun, and a distance calibration component is installed at the end of the infrared thermometer gun. The distance calibration component includes positioning seats installed on both sides of the end of the infrared thermometer gun. Second fixing frames and first fixing frames are respectively screwed and fixed on the two groups of positioning seats. An first adjusting column is inserted into the first fixing frame. One end of the first adjusting column away from the first fixing frame is welded and fixed with a connecting frame, and one end of the connecting frame away from the first adjusting column is fixedly connected to the first adjusting column.

[0007] Preferably, the calibration ring is a circular structure made of plastic material, and the calibration ring and the infrared sensor installed at the end of the infrared thermometer gun are concentric structures.

[0008] Preferably, connecting frames are installed at both ends of the calibration ring, and a first adjusting column and a second adjusting column are respectively installed at the end parts of the two groups of connecting frames.

[0009] Preferably, the connecting frame, the first adjusting column and the second adjusting column are combined into a "U" - shaped structure, and slots are provided inside both the first fixing frame and the second fixing frame.

[0010] Preferably, the first adjusting column and the second adjusting column are respectively inserted into the slots inside the first fixing frame and the second fixing frame, and the lengths of the first adjusting column and the second adjusting column are the same.

[0011] Preferably, a stud is fixedly installed on the outer side of the bottom of the first adjusting column, a U - shaped hole is provided on the side wall of the first fixing frame, and at the same time, the stud passes through the U - shaped hole and is screwed and fixed with a bolt.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The setting of the distance calibration component makes the distance between the object and the infrared sensor at the end of the infrared thermometer a fixed value. This specific distance can be adjusted between the first adjusting column and the first fixing frame, enabling accurate temperature measurement of the object. It will not occur that the temperature measurement result is inaccurate due to the infrared thermometer being too far or too close to the object to be measured, improving the accuracy of temperature measurement by the infrared thermometer.

[0019] Working principle: When measuring the temperature of an object, hold the infrared temperature measuring gun 1 and make the marking ring 20 on the distance calibration component 2 at the end of the infrared temperature measuring gun 1 touch the object, so that the distance between the object and the infrared sensor at the end of the infrared temperature measuring gun 1 is a fixed value. This specific distance can be adjusted between the first adjustment column 22 and the first fixed frame 23, so that accurate temperature measurement of the object can be achieved. The situation that the temperature measurement result is inaccurate due to the infrared temperature measuring gun 1 being far or close to the object to be measured will not occur, thereby improving the accuracy of the temperature measurement by the infrared temperature measuring gun 1;

[0020] An infrared sensor and a laser sight are installed at the end of the infrared temperature measuring gun 1 . The infrared sensor and the laser sight are staggered with the circular marking ring 20 , and no interference occurs between the infrared sensor, the laser sight and the marking ring 20 .

Through the setting of the marking ring 20, the distance between the infrared temperature measuring gun 1 and the object to be measured can be calibrated to improve the accuracy of the infrared temperature measuring gun 1 after measuring temperature.

[0024] As a preferred embodiment, the connection frame 21 , the first adjustment column 22 and the second adjustment column 28 are combined together to form a “U”-shaped structure, and the first fixing frame 23 and the second fixing frame 29 are both provided with slots 24 inside.
