Problems solved by technology
[0004] (1) When the top is too high from the ground, it is difficult to fix the measurement point;
[0005] (2) Inadequate sticking of the tape on the top will cause the measurement point to loosen during the measurement process, which will cause the height to change and cause measurement errors. In severe cases, the temperature measurement point will fall off and the experiment will fail;
[0006] (3) The horizontal and vertical positions cannot be located at the same time, making the position determination inaccurate and increasing the measurement error;
[0007] (4) The layout process needs to constantly adjust the position of the temperature measurement point and the tape, which leads to low work efficiency

Embodiment Construction
[0024] The present invention will be described in detail below through specific embodiments.
[0025] Measuring point layout instrument provided by the present invention, see figure 1 ,include:
[0026] Vertical ruler 1, one end is fixed on the base, used for positioning in vertical direction or height direction;
[0027] A movable scale 2, one end is fixed together with the other end of the vertical scale 1 by a fastener, the other end of the movable scale 2 is a free end, and the movable scale 2 can freely rotate around the fastener And it can stay at any position during the rotation; it is usually used for positioning in the horizontal direction, but it can also be positioned in the vertical direction after connecting with the vertical scale 1 in the vertical direction; and
[0028] Movable suspension arm 3, one end is fixed together with the other end of described vertical ruler 1 by described fastener, and the other end is the free end that can hang positioning label 1...

The invention discloses a measuring point placement instrument which comprises a vertical ruler, a movable ruler and a movable suspension arm, wherein one end of the vertical ruler is fixed on a base; one end of the movable ruler is fixed with the other end of the vertical ruler together by a fastener; the other end of the movable ruler is a free end; the movable ruler freely rotates around the fastener, and can stop at any position in a rotating process; one end of the movable suspension arm is fixed with the other end of the vertical ruler together by the fastener; the other end of the movable suspension arm is a free end capable of suspending a location label; and the movable suspension arm freely rotates around the fastener, and can stop at any position in the rotating process. The measuring point placement instrument has the advantages that measuring points are placed conveniently, quickly and precisely. Heights and horizontal distances of the measuring points can be adjusted flexibly to ensure that space coordinates of the measuring points meet specified requirements; the working efficiency is improved greatly; and a situation that an experiment fails due to the fact that the measuring points get loose or fall off is avoided.
Description
technical field [0001] The invention relates to an instrument, in particular to a measuring point layout instrument, which is mainly used when the measuring point is suspended in the air and the spatial coordinates are specified. Background technique [0002] In real life and work, it is often necessary to measure the temperature, humidity or other parameters of a fixed point suspended in the air. For example, when testing the energy efficiency of a refrigerator, it is necessary to measure the temperature of a fixed point in the refrigerator or freezer, and the measurement point has requirements for height and horizontal position. Usually, an ordinary ruler is used to determine the measurement point, such as image 3 As shown, for example, the method for determining a certain measuring point in the first space 8 of the refrigerator is to first measure the required height by using a common ruler 11, and then stick the free end of the hanging line of the positioning label 12 to...
