Description

Technical Field

[0001] This utility model relates to the field of environmental testing equipment calibration technology, and in particular to a measuring point fixing device for calibrating environmental testing equipment. Background Technology

[0002] In the calibration of environmental testing equipment, such as constant temperature and humidity chambers and high and low temperature test chambers, accurate positioning and secure fixing of measurement points are crucial prerequisites for ensuring the accuracy of calibration results. Traditional methods of fixing measurement points mainly rely on manual operation, where operators place the measurement sensors by hand or on simple supports. This method has several drawbacks: First, the positioning accuracy is low, as manual operation makes it difficult to ensure precise alignment between the measurement point and the equipment calibration point, easily introducing systematic errors. Second, the fixing is not secure; changes in the internal environment of the equipment or slight vibrations during calibration can easily cause sensor displacement, affecting the stability of measurement data. Third, the operation is cumbersome, requiring repeated adjustment of the sensor position for each calibration, which is time-consuming and labor-intensive, severely reducing the efficiency of calibration work.

Detailed Implementation

[0012] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solution of this utility model embodiment is clearly and completely described as follows: A measuring point fixing device for calibrating environmental testing equipment includes a U-shaped clamp 1. A screw 5 penetrates the bottom of the inner side of the clamp 1. One end of the screw 5, which extends into the clamp 1, is fixedly connected to a pressing plate 7. An anti-slip pad 8 is laid on the surface of the pressing plate 7. A wing nut 6 is threadedly connected to the part of the screw 5 near the outer side of the clamp 1. Rotating the wing nut 6 can drive the screw 5 to rise and fall, thereby realizing the clamping and fixing of the pressing plate 7 to the edge of the equipment shelf. The base 4 at one end of the clamp 1 is connected to a telescopic structure through a damping shaft. The telescopic structure consists of a telescopic rod A2 and a telescopic rod B3. The connecting rod 201 at the end of the telescopic rod A2 is inserted into the groove of the base 4. The damping shaft can realize the angle adjustment and folding storage of the telescopic rod A2. The telescopic rod B3 is inserted into the telescopic rod A2. The anti-slip layer on the contact surface of the two can ensure the stability of the position after telescopic extension and prevent self-slip. The positioning structure at the top of the telescopic structure is used to realize The key to the angle positioning of the rotating component 13 is that the circular groove at the end of the telescopic rod B3 contains multiple ball bearings 18, which can reduce the frictional resistance when the rotating component 13 rotates. The spring 16 outside the top rod 17 provides downward pulling force to the cap 12. The top rod 17 is fixed to the top of the telescopic rod B3. When the cap 12 is pulled upward to rotate the rotating component 13 to the appropriate position, the cap 12 is positioned by the top rod 17 under the pulling force of the spring. The insert plate 1202 at the bottom of the cap 12 cooperates with the slot 301 of the telescopic rod B3 to achieve precise docking. The positioning holes 1201 on the four sides of the cap 12 can engage with the connecting rod of the rotating component 13, thereby completing the angle locking of the rotating component 13. The rotating component 13 has a ring-shaped structure. Its two connecting rods are fixedly connected to the telescopic arm a9 by bolts 14 and nuts 15. The telescopic arm a9 and the telescopic arm b10 slide together. The multiple mounting holes 11 on both can flexibly select the installation position according to the sensor size and installation requirements to achieve synchronous fixing of multiple sensors.

[0013] In use, first, clip the U-shaped clip 1 onto the appropriate edge of the shelf of the environmental testing equipment, tighten the wing nut 6, and make the pressing plate 7 cooperate with the anti-slip pad 8 to firmly fix the device; then, according to the position of the calibration point, adjust the damping shaft to change the angle of the telescopic rod A2, and pull the telescopic rod B3 to adjust the overall telescopic length; next, rotate the rotating part 13 to the appropriate angle, press down the cap 12, and make the positioning hole 1201 engage with the connecting rod of the rotating part 13 to complete the angle locking; finally, slide the relative position of the telescopic arm a9 and the telescopic arm b10, fix the measuring sensor in the designated position through the mounting hole 11, and the calibration work can be carried out.

[0014] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
