[0002] In current electrical testing laboratories, temperature rise testing is a common test for electrical components. When measuring ambient temperature, the measurement point needs to be approximately 1 meter away from the sample, and the measurement height should be about half the sample height. The traditional installation method is to first install the circuit breaker on the test rack, manually adjust the height of the test tube clamp, and then adjust the height of the test tube. For greater accuracy, auxiliary tools such as a measuring tape are also needed to ensure that the environmental measurement meets the test point standards. The entire process is inefficient and imprecise. Therefore, there is an urgent need in this technical field for an environmental rack that is easy to adjust and measure distances from.

[0027] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0028] This utility model provides an environmental frame that is easy to adjust and measure distances, such as Figure 1 and Figure 5 As shown, it includes a base 1 and a support rod 2 that is fixedly connected to it and extends vertically upward. A test tube 8 that can move along its length is fitted around the outer periphery of the support rod 2. A motor protective shell 3 is located on the right side of the support rod 2, and its bottom surface is fixed to the base 1. The motor 11 is sealed inside the motor protective shell 3, which can protect the motor 11. The forward and reverse rotation of the motor 11 is controlled by a motor forward and reverse switch 5. The outer periphery of the support rod 2 is engraved with scale lines 4, which can determine the height of the test tube 8. The motor forward and reverse switch 5 is located on the middle left side of the support rod 2, which can control the forward and reverse rotation of the motor 11, thereby controlling the up and down movement of the test tube 8.

[0029] like Figure 3 As shown, a cavity is formed inside the base 1, and the first gear 12 is located inside the cavity of the base 1; it also includes a second gear 13, whose center is connected to the motor shaft and meshes with the left side of the first gear 12; the support rod 2 has a hollow structure, and the lifting rod 14 is set inside the hollow structure of the support rod 2, with its lower part connected to the second gear 13.

[0030] like Figures 1 to 4As shown, the lifting block 15 is installed inside the support rod 2 and threadedly connected to the outer circumference of the lifting rod 14, forming a helical pair, which can move up and down along the length of the lifting rod 14; one end of the test tube clamp 7 is fixedly connected to the lifting block 15, and the clamp end extends horizontally to the outside of the support rod 2 for easy clamping of the test tube 8; the test tube 8 is installed in the right clamp of the test tube clamp 7, which can be detached, and the height of the test tube 8 can also be freely adjusted by adjusting the height of the lifting block 15; a scale indicator 6 is provided on the side of the test tube clamp 7 near the support rod 2, with the scale... Indicator 6 points to scale line 4. The scale indicator 6 is a pointer with an L-shaped bend, pointing horizontally to scale line 4 for accurate scale indication and improved reading accuracy. The rangefinder 9 is fixedly mounted on the side of the test tube clamp 7 near the clamp head. The rangefinder 9 extends vertically downwards and has a rangefinder lamp clamp at its lower end, which holds the rangefinder lamp 10. The rangefinder lamp 10 is located inside the rangefinder lamp clamp of the rangefinder 9, corresponding to the bottom of the test tube 8, allowing measurement of the distance from the bottom of the test tube 8 to the sample. The emission axis of the rangefinder lamp 10 is parallel to the axis of the test tube 8, improving distance measurement accuracy.

[0031] The working principle of this utility model is as follows:

[0032] An environmental frame for easy adjustment and distance measurement is provided. First, turn on the distance measuring light 10 and measure the approximate distance from the bottom of the test tube 8 to the sample. If it is greater than 1m, move closer to the sample; if it is less than 1m, move further away by 1m, until the distance from the sample to the bottom of the test tube 8 is about 1m. Then, place the thermocouple inside the test tube 8 and measure the height and center position of the sample using the distance measuring light 10 and the scale line 4. Then, drive the motor 11 through the motor forward / reverse switch 5, and convert the motor rotation into linear displacement of the lifting rod through gear transmission. The lifting block 15 drives the test tube 8 up and down, adjusting the height of the test tube 8 until the height of the thermocouple inside the test tube 8 is half the height of the sample. This allows for environmental measurement of the temperature rise test.

[0033] The standard ambient temperature measurement position is half the height of the sample. Therefore, the bottom and top scales of the sample can be observed according to scale line 4 to obtain the middle position of the sample.

[0034] By integrating mechanical transmission and electronic ranging, the problem of low efficiency and large error in traditional methods is solved, making it particularly suitable for temperature rise testing of electrical equipment such as circuit breakers and transformers.
