Description

Technical Field

[0001] The utility model relates to the technical field of testing instruments, in particular to an equipotential testing instrument. Background Art

[0002] The potential equalization tester can measure the voltage difference between different points in the electrical system to ensure that the voltage between these points is at the same level to prevent electric shock, equipment damage or other safety issues. For test equipment such as the potential equalization tester, the cleanliness of the display is crucial for accurate readings. Cleaning the screen can prevent the influence of dirt or water droplets on the test results and ensure the accuracy of the test.

[0003] After searching, the patent document with the number "CN217278631U" provides "a portable equipotential tester.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 As shown, the utility model provides a technical solution: an equipotential tester, comprising a tester body 1 and a protective cleaning mechanism 2, wherein the protective cleaning mechanism 2 is arranged on the outer side of the tester body 1;

[0022] The protective cleaning mechanism 2 includes a fixed component 21, a protective component 22, a sliding component 23, a cleaning component 24, a guide component 25 and a blowing component 26. The fixed component 21 is arranged on the outside of the tester body 1, the protective component 22 is arranged on the upper end of the fixed component 21, the sliding component 23 is arranged on the inner side of the protective component 22, the cleaning component 24 is arranged on the lower end of the sliding component 23, the guide component 25 is arranged at one end of the fixed component 21, and the blowing component 26 is arranged inside the guide component 25.

[0023] Furthermore, the fixing assembly 21 includes a cover head 211 and a fastening slide rail 212. The cover head 211 is arranged on the outer side of the tester main body 1, and the fastening slide rail 212 is arranged on the inner side of the cover head 211. By sliding the tester main body 1 along the inner side of the cover head 211, the protective cleaning mechanism 2 can be fixed on the tester main body 1. The setting of the fastening slide rail 212 makes the opening size of the cover head 211 slightly smaller than the size of the tester main body 1, and the two are interference fit, so that the cover head 211 can be stably fixed.

[0024] Furthermore, the protective component 22 includes a protective cover 221 and a slide groove 222. The upper end of the cover head 211 is rotatably connected to the protective cover 221, and both sides of the lower end of the protective cover 221 are fixedly connected to the slide grooves 222. When the tester body 1 is not in use, the protective cover 221 is rotated to a closed state to protect the display of the tester body 1 from damage caused by bumps.

[0025] Furthermore, the sliding assembly 23 includes a connector 231 and a limiting cap 232. The connector 231 is slidably connected inside the slide groove 222. Limiting caps 232 are provided at both ends of the connector 231. By moving the limiting cap 232, the cleaning assembly 24 can be driven to move along the direction of the slide groove 222 to scrape and clean the display of the tester body 1 to ensure the cleanliness of the display and avoid stains that affect data reading.

[0026] Furthermore, the cleaning component 24 includes a connecting plate 241 and a cleaning pad 242. The upper end of the connector 231 is screwed connected to the connecting plate 241, and the lower end of the connecting plate 241 is adhesively connected to the cleaning pad 242. The cleaning pad 242 is a soft pad that absorbs alcohol, which can ensure that the stains will not be scratched while cleaning. When the cleaning pad 242 needs to be replaced, the screws fixing the connecting plate 241 are removed, and then the connecting plate 241 is removed, and then the new cleaning pad 242 is replaced and reinstalled.

[0027] Furthermore, the guide assembly 25 includes a guide cover 251 and a guide hood 252. The guide cover 251 is provided at one end of the hood head 211. The guide hood 252 is fixedly connected to both sides of the guide cover 251. There is a gap between the guide cover 251 and the tester body 1 to ensure that the airflow has sufficient flow space. The guide hood 252 can guide the air flowing out from the bottom of the guide cover 251 to the display, thereby accelerating the volatilization rate of the alcohol on the display.

[0028] Furthermore, the blowing assembly 26 includes a fixing seat 261, a motor 262 and a fan blade 263. The fixing seat 261 is fixedly connected inside the guide cover 251, one end of the fixing seat 261 is installed with a motor 262, and the other end of the motor 262 is rotatably connected to the fan blade 263. Starting the motor 262 can drive the fan blade 263 to rotate at a high speed, so that the airflow can flow in the guide cover 251, which can play a role in auxiliary heat dissipation.

[0029] Working principle: First, move an equipotential tester to the working position. In the first step, slide the tester body 1 along the inner side of the cover head 211 to fix the protective cleaning mechanism 2 on the tester body 1. The setting of the fastening slide rail 212 makes the opening of the cover head 211 slightly smaller than the size of the tester body 1. The two are interference fit, so that the cover head 211 can be stably fixed. In the second step, when the tester body 1 is not in use, rotate the protective cover 221 to a closed state to protect the display of the tester body 1 from damage caused by bumps. In the third step, the cleaning component 24 can be driven to move along the direction of the slide groove 222 by moving the limit cap 232 to scrape and clean the display of the tester body 1 to ensure that the tester body 1 is not damaged. To ensure the cleanliness of the display and avoid stains that affect data reading, the cleaning pad 242 is a soft pad that absorbs alcohol, which can ensure that the stains will not be scratched while cleaning. When the cleaning pad 242 needs to be replaced, the screws that fix the connecting plate 241 are removed, and then the connecting plate 241 is removed. After replacing the new cleaning pad 242, it is reinstalled. In the fourth step, starting the motor 262 can drive the fan blades 263 to rotate at high speed. There is a gap between the guide cover 251 and the tester body 1, which can ensure that the airflow has enough flow space. The guide cover 252 can guide the air flowing out of the bottom of the guide cover 251 to the display, thereby accelerating the volatilization rate of the alcohol on the display. In this way, the use process of an equipotential tester is completed.
