Description

Technical Field

[0001] The utility model relates to the technical field of pressure-resistant instruments, in particular to a heat dissipation structure of a pressure-resistant instrument used for the production and processing of special-shaped electric heating elements. Background Art

[0002] The withstand voltage tester can be called an electrical insulation strength tester, a dielectric strength tester, etc. according to its function. Its working principle is to apply a voltage higher than the normal working voltage to the insulator of the device under test for a specified period of time. The voltage applied thereto will only produce a very small leakage current, and the insulation is better. The withstand voltage tester is often used in conjunction with a heat dissipation structure during use.

[0003] According to the description of a withstand voltage instrument for producing and processing special-shaped electric heating elements disclosed in the patent website (authorization announcement number: CN213715379 U), "The utility model discloses a withstand voltage instrument for producing and processing special-shaped electric heating elements, which relates to the technical field of electronic instruments, including an instrument box, a detection table is fixedly installed on the upper surface of the instrument box, and a detection device is fixedly installed on the upper surface of the instrument box. The utility model uses a movable connection between a limit pin and a limit rod, and cooperates with a movable block and a pressure measuring plate to be connected through a connecting rod. The movable block and the pressure measuring plate slide on the second slide rod, and then the pressure measuring probe is used to press and hold the special-shaped electric heating element on the detection table, and the instrument box is opened for detection, thereby avoiding the need for the operator to manually test the withstand voltage of the product when using a withstand voltage tester to test the special-shaped electric heating element. The withstand voltage tester will generate high voltage when in use. If the operation is not careful, electric shock accidents may occur, resulting in reduced safety of the equipment and reduced work efficiency, thereby achieving the effect of improving the safety and work efficiency of the equipment."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the movable block slides downward on the first slide bar and the second slide bar by using the operating handle, and then the connecting rod is used to drive the pressure measuring plate to move downward, and then the pressure measuring probe is pressed on the special-shaped electric heating element. In actual use, since the position of the cooling fan of the device is fixed, the instrument body inside the workbench cannot be fully cooled, which affects the heat dissipation efficiency. At the same time, since the electric heating element is prone to high temperature during the test, the device only allows the electric heating element to cool down naturally, which affects the operating efficiency of the staff. Therefore, it is necessary to improve the heat dissipation structure of a pressure-resistant instrument for the production and processing of special-shaped electric heating elements to solve the above problems.
