Generally speaking, it is to put electrical equipment into a high-voltage environment for detection to verify whether its insulation performance meets the standard requirements.

[0003] In withstand voltage testing, a withstand voltage tester is usually used. A withstand voltage tester is a test instrument used to test the insulation strength and withstand voltage ability of electrical equipment. An AC / DC insulation withstand voltage tester can apply a high voltage (AC or DC) to the insulation part of the device under test to evaluate its insulation strength and withstand voltage ability.

[0004] The inventor found the following problems in the prior art during the implementation of the present utility model: 1. The existing withstand voltage testers usually adopt the natural heat dissipation method, with low heat dissipation efficiency. Long-term operation of the equipment will cause the temperature to be too high, affecting the accuracy of the equipment; 2. In the daily use of the existing withstand voltage testers, the top cover and the housing are usually fixedly installed, and it is not easy to quickly open the top cover, which affects the use of the equipment by the user and results in low work efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] The connector assembly 4 includes a main fixing block 401 installed on one side surface of the housing 1 and a sub-fixing block 402 installed on one side surface of the top cover 3. A sleeve 403 is installed on the inner wall of the main fixing block 401, an annular baffle 404 is installed on the inner wall of the sleeve 403, an insertion rod 405 is installed on the inner wall of the annular baffle 404, and a spring 406 is provided on the outer wall of the insertion rod 405.

[0026] The ventilation component 6 includes side plates 601 installed on both sides of the housing 1. A blade 602 is rotatably connected to the inner wall of the side plate 601. A worm gear 603 is installed on the outer wall of the blade 602. A worm 604 is installed on the outer wall of the worm gear 603. A reduction motor 605 is installed at one end of the worm 604.

[0027] The heat dissipation component 7 includes a bracket 701 installed on one side surface of the side plate 601. A servo motor 702 is installed on one side surface of the bracket 701. A driving rod 703 is installed at the output end of the servo motor 702, and a fan blade 704 is installed on the outer wall of the driving rod 703.

[0028] In this embodiment, as Figure 1 shown, an anti-slip sheet is adhesively bonded to the bottom of the housing 1; through this design, the friction between the housing 1 and the plane can be effectively increased, avoiding the equipment from sliding due to external factors and causing damage to the equipment.

[0029] In this embodiment, as Figure 1 shown, a sealing ring is provided at the connection between the top cover 3 and the housing 1; through this design, the connection between the top cover 3 and the housing 1 is made more tight, preventing dust from entering.

[0030] In this embodiment, as Figure 1 shown, buffer pads are adhesively bonded to both sides of the withstand voltage tester body 5; through this design, when the housing 1 is affected by external factors and vibrates, due to the buffering effect of the buffer pads, it is prevented that the withstand voltage tester body 5 makes hard contact with the inner wall of the housing 1, avoiding damage to the withstand voltage tester body 5.

[0031] In this embodiment, as Figure 2 shown, a jack with an internal dimension structure consistent with the external dimension structure of the insertion rod 405 is provided on one side surface of the secondary fixing block 402, and the insertion rod 405, the annular baffle 404, the sleeve 403 and the spring 406 form an elastic mechanism; through this design, when the user needs to use the withstand voltage tester body 5, the insertion rod 405 can be toggled to one side, making the annular baffle 404 move to one side and the spring 406 compress. At this time, the insertion rod 405 is pulled out from the jack of the secondary fixing block 402, facilitating the quick opening of the top cover 3.

[0032] In this embodiment, as Figure 3 shown, the reduction motor 605, the worm 604 and the worm gear 603 form a transmission mechanism with the blade 602; through this design, the reduction motor 605 can be started as needed. The reduction motor 605 drives the blade 602 to rotate through the worm 604 and the worm gear 603, enabling the opening and closing control of the ventilation openings on both sides of the housing 1, and the size of the opening and closing can be adjusted, facilitating the ventilation and heat dissipation inside the housing 1.

[0033] In this embodiment, as Figure 4As shown, the servo motor 702 and the fan blade 704 form a transmission mechanism through the drive rod 703; a large amount of heat will be generated during the daily use of the pressure resistance testing machine body 5. When the temperature is relatively high, it will affect the testing accuracy. The servo motor 702 can be started. The servo motor 702 drives the fan blade 704 to rotate through the drive rod 703, which can effectively dissipate the heat of the pressure resistance testing machine body 5 in the housing 1, avoiding too high temperature and affecting the use of the equipment.

[0034] The usage method and advantages of the present utility model: When this pressure resistance testing machine is in use, the working process is as follows:

[0035] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, first place the equipment in a suitable position, then move the insertion rod 405 to one side, so that the annular baffle 404 moves to one side, and the spring 406 is compressed. At this time, the insertion rod 405 is pulled out from the jack of the secondary fixing block 402. Then rotate and open the top cover 3 and the housing 1 through the hinge 2. Then test the material to be tested through the pressure resistance testing machine body 5. At the same time, start the reduction motor 605. The reduction motor 605 drives the blade 602 to rotate through the worm 604 and the worm gear 603, opening the ventilation openings on both sides of the housing 1. Then start the servo motor 702. The servo motor 702 drives the fan blade 704 to rotate through the drive rod 703, which can effectively dissipate the heat of the pressure resistance testing machine body 5 in the housing 1. After the use is completed, turn off the servo motor 702, then start the reduction motor 605. The reduction motor 605 drives the blade 602 to rotate through the worm 604 and the worm gear 603, closing the ventilation openings on both sides of the housing 1. Then move the insertion rod 405 to one side, so that the annular baffle 404 moves to one side, and the spring 406 is compressed. Then rotate and close the top cover 3. At this time, the jack is located on the right side of the insertion rod 405. Release the insertion rod 405, and the spring 406 resumes, driving the annular baffle 404 and the insertion rod 405 to move to the right, so that the insertion rod 405 is inserted into the jack, thereby quickly fixing the top cover 3 and the housing 1.
