[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please refer to Figures 1 to 6 :

[0030] Example 1: This utility model proposes a touch screen power frequency withstand voltage tester, including: an operating table body 1, the bottom of the operating table body 1 is a rectangular structure, and a fixed base 101 is rotatably mounted on the bottom of the operating table body 1; universal wheels are installed at the included angle of the bottom edge of the fixed base 101, and a guide vertical rod 102 is installed at the middle position of the bottom of the fixed base 101; the guide vertical rod 102 is a cylindrical structure, and a limit plate 103 is installed at the bottom of the guide vertical rod 102, and a guide slide plate 104 is slidably mounted on the outer side of the guide vertical rod 102; the guide slide plate 104 is a cross-shaped structure, and a spring is installed at the middle position of the guide slide plate 104, the top of the guide slide plate 104 is connected to the bottom of the fixed base 101 through the spring, and a pedal 105 is installed on the front end of the guide slide plate 104; positioning rods 106 are installed on the top of the side ends of the guide slide plate 104; the positioning rods 106 are cylindrical structures, and the top of the positioning rods 106 penetrates the fixed base 101 and is inserted into the bottom of the operating table body 1.

[0031] In this embodiment, when the touch screen power frequency withstand voltage tester is being maintained, when the main body 1 of the operating table is close to the wall, the pedal 105 is stepped down at the bottom front side of the main body 1 and the bottom of the fixed base 101 to move the guide slide 104. The side end of the guide slide 104 moves the positioning rod 106 downward. The guide slide 104 moves downward along the guide vertical rod 102. The limiting plate 103 prevents the guide slide 104 from moving too far downward. After the positioning rod 106 moves downward, it loses the fixation of the main body 1 of the operating table. The main body 1 of the operating table is rotated at the top of the fixed base 101, so that the rear side of the main body 1 of the operating table is rotated to the front, making it easier to perform maintenance operations on the various electronic components inside the tester in a suitable position.

[0032] In Example 2, based on Example 1, an electronic component storage tank 2 is provided on the rear side of the main body 1 of the operating table; a support plate 201 is rotatably mounted on the bottom of the outer side of the electronic component storage tank 2; a locking block 202 is installed on the top of the support plate 201, wherein the locking block 202 is installed on the top of the outer side of the electronic component storage tank 2; a guide rail 1 203 is installed at the bottom of the electronic component storage tank 2; a guide rail 204 is installed on the inner side of the support plate 201, wherein a limit connecting plate is installed at the outer end of the guide rail 204; a guide slide 205 is slidably mounted on the outer side of the guide rail 1 203 and the guide rail 204; a sliding plate 206 is installed on the top of the guide slide 205; a circuit board 207 is installed on the top of the sliding plate 206. The touch screen power frequency withstand voltage tester is in operation... During maintenance, the locking block 202 is removed from the top of the electronic component storage tank 2 on the outer side of the main body 1 of the operating table to fix the support plate 201. The support plate 201 rotates outward on the outer side of the electronic component storage tank 2. The bottom of the support plate 201 is engaged and installed on one side of the electronic component storage tank 2, so that the inner side of the support plate 201 is horizontal with the bottom of the electronic component storage tank 2 after rotation. The guide slide 205 moves outward along the guide rail 1 203 and the guide rail 204. The guide slide 205 drives the top sliding plate 206 to move outward. The sliding plate 206 drives the circuit board 207 to move outward to a relatively wide area, which makes it easier for the operator to maintain the circuit board 207 inside the testing instrument in a relatively wide position, thus improving the efficiency of maintenance.

[0033] In Example 3, based on Example 1, the top side of the main body 1 of the operating table is inclined, and a storage groove 3 is provided on the top side of the main body 1 of the operating table. A guide groove 301 is provided on the rear top side of the main body 1 of the operating table. The inner end of the guide groove 301 is connected to the storage groove 3, and a collection box 302 is installed on the outer end of the guide groove 301. A rotating rod 303 is rotatably installed on the top side of the storage groove 3. An operating platform 304 is installed on the outer side of the rotating rod 303, wherein a touch screen operating panel is provided on one side of the operating platform 304. A positioning side plate 305 is installed through the side of the top of the main body 1 of the operating table. A spring is installed on the outer side of the positioning side plate 305, and a fixing plate 306 is installed on the outer side of the positioning side plate 305 via the spring; fixing rods 307 are installed at both ends of the fixing plate 306; the side ends of the fixing rods 307 penetrate the side ends of the positioning side plate 305 and are inserted into the top side of the main body 1 of the operating table; two drive screws 308 are rotatably installed inside the storage slot 3, and a servo motor is installed on one side of the storage slot 3. The output end of the servo motor is connected to one of the drive screws 308 via a pulley; a cleaning plate 309 is installed on the outer side of the two drive screws 308; a brush is provided on the side of the cleaning plate 309, and the brush on the side of the cleaning plate 309... The brush is slidably mounted on the side of the operating plate 304. When the touchscreen power frequency withstand voltage tester is in use, pulling the fixing plate 306 outward from the outside of the positioning side plate 305 causes the fixing rod 307 to move outward away from the top side of the main body 1 of the operating table, thus losing the fixing force on the positioning side plate 305. Rotating the positioning side plate 305 causes the operating plate 304 to move via the rotating rod 303. The operating plate 304 rotates at the top of the storage slot 3, and the touchscreen operating panel on the side of the operating plate 304 rotates to the outside for easy operation of the withstand voltage test. After use, the operating plate 304 rotates again, causing the touchscreen operating panel to rotate back into the storage slot. Inside the storage compartment 3, the touchscreen operation panel is protected from dust accumulation over time, preventing it from affecting operation. A servo motor inside the storage compartment 3 drives a drive screw 308 via a pulley. Two drive screws 308 are connected by pulleys, causing the cleaning plate 309 to move within the storage compartment 3. Brushes on the side of the cleaning plate 309 clean the touchscreen operation panel on the side of the operating carrier plate 304, reducing the accumulation of impurities. The cleaned impurities then flow through the guide channel 301 into the collection box 302, minimizing the problem of impurities falling to other areas.

[0034] The working principle of this embodiment is as follows: Pulling the fixing plate 306 outward from the outside of the positioning side plate 305 causes the fixing rod 307 to lose its fixation to the positioning side plate 305. Rotating the positioning side plate 305 causes the operating plate 304 to rotate at the top of the storage slot 3 via the rotating rod 303. The touch screen operation panel on the side of the operating plate 304 rotates to the outside to facilitate the operation of the pressure resistance test. After use, the operating plate 304 rotates so that the touch screen operation panel rotates into the storage slot 3, which plays a protective role. The servo motor inside the storage slot 3 drives two drive screws 308 to rotate simultaneously through the pulley. The two drive screws 308 drive the brush on the side of the cleaning plate 309 to clean the touch screen operation panel on the side of the operating plate 304.

[0035] When equipment maintenance is required, when the main body 1 of the operating table is close to the wall, the pedal 105 is pressed down at the bottom of the fixed base 101, which drives the guide slide plate 104 to move down along the guide vertical rod 102. After the side positioning rod 106 of the guide slide plate 104 moves down, it loses the fixation of the main body 1 of the operating table. The main body 1 of the operating table rotates on the top of the fixed base 101 so that its rear side rotates to the front. The rotating support plate 201 on the outside of the electronic component storage tank 2 is in a horizontal position with the bottom of the electronic component storage tank 2. The guide slide 205 moves outward along the first guide rail 203 and the second guide rail 204. The guide slide 205 drives the top sliding plate 206 to move outward. The sliding plate 206 drives the circuit board 207 to move outward into a relatively wide area, which makes it convenient for the operator to maintain the circuit board 207 inside the testing instrument in a relatively wide position.
