Problems solved by technology

[0004] During the calibration process, it is necessary to pay attention to the size of the measurement object. If the measurement object is too small, the background radiation source will be exposed, and multi-level contrast measurement should be used to ensure the effectiveness of the calibration. The existing device has the problem that the measured object cannot shield the background. The radiation source and the inability to effectively shield mutual interference in multiple temperature comparison measurement rooms make the calibration effect not good

Embodiment 1

[0029] Example 1: Please refer to Figure 1-2 , a waterproof infrared thermometer temperature calibration device, including a base 1, also includes a comparison box 2 and an adjustment mechanism 3; the adjustment mechanism 3 is fixedly connected to one side of the base 1, and the adjustment mechanism 3 is equipped with a locking Component 4, the locking component 4 is used to fix the infrared thermometer, and the adjustment mechanism 3 is used to adjust the position of the fixed infrared thermometer relative to the comparison box 2;

[0030] see Figure 2-3 , the comparison box 2 is fixed on the base 1, the comparison box 2 is fixed on the base 1 by welding or screw fastening, the comparison box 2 is located on the side away from the adjustment mechanism, the comparison box 2. It is composed of a number of temperature chambers 6 separated by partitions 5 arranged in parallel and evenly distributed. Each temperature chamber 6 is hinged with a cover plate 7 through the rotation...

Embodiment 2

[0036] Embodiment 2: This embodiment makes supplementary explanations based on the previous implementation: please refer to Image 6 , the block 19 is a cube, the width of the block 19 is greater than the width of the limit chute 17, in order to increase the stability of the structure, the block 19 can be T-shaped, and the width of the upper end of the block 19 is greater than that of the limit chute width.

[0037] The working principle of the present invention is: by manually pulling the short semicircle snap ring 21, the thermometer is placed inside, the compression spring 22 shrinks the distance between the long semicircle snap ring 20 and the short semicircle snap ring 21, and the infrared thermometer is fixed on the On the locking assembly 4, multiple adjustment knobs 13 can be selectively opened according to the calibration requirements, so that the temperature generating device 8 in the corresponding temperature chamber 6 can be activated, and different step temperatur...

Abstract

The invention discloses a temperature calibration device for a waterproof infrared thermometer, which relates to the technical field of thermometer production and inspection, and comprises a base, a comparison box body and an adjusting mechanism, wherein the adjusting mechanism is fixedly connected to one side of the base, and a locking assembly is arranged on the adjusting mechanism in a matched mode. The comparison box body is fixed on the base, the comparison box body is composed of a plurality of temperature bins which are divided by partition plates which are uniformly distributed in parallel, and a cover plate is rotationally hinged to the temperature bins through the comparison box body. Compared with the prior art, the device has the beneficial effects that interference among the temperature bins is effectively prevented by the comparison box body with interlayers on the partition plates, so that the measurement and calibration precision is ensured, when the device is used, the cover plate is closed, the corresponding temperature generation device is started, and the infrared thermometer located on the locking assembly moves, can measure temperature data on different cover plates, the large-area cover plate effectively shields interference of a temperature generating device with the inner wall serving as a radiation source, and calibration precision is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of production and inspection of thermometers, in particular to a temperature calibration device for waterproof infrared thermometers. Background technique [0002] In the production process, infrared temperature measurement technology plays an important role in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy saving. In recent years, the non-contact infrared human body thermometer has developed rapidly in technology, its performance has been continuously improved, and its functions have been continuously enhanced. Compared with contact temperature measurement methods, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life. [0003] After the infrared thermometer is produced, in order to ensure good use effect and measurement accuracy, it usually needs to be calibrated before it can be pu...
