Description

Technical Field

[0001] This utility model relates to the technical field of pressure resistance testers, and in particular to a pressure resistance tester for an ozone generator. Background Technology

[0002] An ozone generator is a device used to produce ozone gas. It is widely used in water treatment, air purification, and food processing. Most of them use high-voltage discharge generators, which use a high-voltage current of a certain frequency to create a high-voltage corona electric field. This causes oxygen molecules in or around the electric field to undergo an electrochemical reaction, thereby producing ozone. Since it is an electrical device, it needs to be tested for withstand voltage. The withstand voltage test is the process of applying a high voltage to the insulating material or insulating structure without damaging the performance of the insulating material. Generally speaking, the main purpose of the withstand voltage test is to check the ability of the insulation to withstand the working voltage or overvoltage, and thus to verify whether the insulation performance of the product equipment meets the safety standards. Conventional withstand voltage testers are mostly box-shaped integrated designs. During the withstand voltage test of electrical devices, it is necessary to pre-connect and clamp the ground wire and test wiring, and then use a measuring rod or measuring clamp to contact the power connector for measurement. During this process, insulation protection is required for the tester, ozone generator, and operators. The conventional method is to place insulating pads for isolation. The operation is relatively cumbersome and prone to errors, which may lead to certain safety hazards. In addition, various ground wires and test clamps and other connecting wires cannot be stored together with the withstand voltage tester. They are relatively scattered, and the wiring terminals are relatively exposed and lack anti-detachment protection, which poses a risk of accidental dragging during operation. Utility Model Content

[0003] The purpose of this utility model is to provide a withstand voltage tester for ozone generators, which can provide multiple insulation protection for the withstand voltage tester and the device under test, while also being integrated with the withstand voltage tester for easy carrying and storage. This simplifies the initial insulation preparation steps, optimizes insulation performance, and improves operational safety. At the same time, it integrates the storage and use of various connecting wires to avoid omissions. In addition, it ensures the stability of various wiring connections and prevents accidental detachment that could cause safety hazards and affect the accuracy of the test.

[0004] To achieve the above objectives, a withstand voltage tester for an ozone generator is provided, comprising: a tester body, a wiring port located on the lower right front side of the tester body, a torsion spring hinge fitted onto the upper edge of the wiring port, an L-shaped cover fixedly connected to the outer rotating end of the torsion spring hinge, a plurality of slots symmetrically formed on the bottom side of the L-shaped cover, a U-shaped shell fixedly fitted onto the bottom outer side of the tester body, side frame plates symmetrically fixed to the bottom of the left and right sides of the U-shaped shell, a first insulating pad fixedly connected to the bottom of the side frame plate, a sleeve frame fixedly connected to the center of the side of the first insulating pad opposite to the U-shaped shell, a storage box slidably fitted onto the inner side of the sleeve frame, a second insulating pad mounted on the right side of the first insulating pad, a damping hinge fitted between the first insulating pad and the second insulating pad, and a damping hinge between the first insulating pad and the second insulating pad. A non-slip insulating pad is installed directly beneath each pad. An insulating base is symmetrically fixed to the top of each non-slip insulating pad. The top of each insulating base is fixedly connected to the first insulating pad and the second insulating pad, respectively. By using foldable first and second insulating pads, each with an insulating base and non-slip insulating pad, multiple layers of insulation protection are provided for the withstand voltage tester and the device under test. This design allows for integrated storage and transport with the withstand voltage tester, simplifying the initial insulation preparation steps, optimizing insulation performance, and improving operational safety. A storage box is also added to the bottom of the withstand voltage tester for integrated storage and use of various connecting wires, preventing omissions. Furthermore, torsion spring hinges are installed along the wiring ports, rotating L-shaped covers with corresponding slots to prevent detachment and ensure stable connection of various wires, avoiding accidental pull-off that could cause safety hazards and affect test accuracy.

[0005] According to the aforementioned withstand voltage tester for an ozone generator, the bottom edges of the slot are rounded, and rubber sheets are attached to the inner surfaces of the slot, with the rubber sheets pressed against the test wiring to prevent scratches on the wiring sheath.

[0006] According to the aforementioned withstand voltage tester for an ozone generator, a groove is provided on the top left side of the second insulating pad, and a strip is fixedly connected to the upper right side of the U-shaped shell. During storage, the second insulating pad is locked in place by engaging the groove and the strip. A secondary locking mechanism is applied to the stored second insulating pad to prevent it from unfolding under stress during transport.

[0007] According to the aforementioned withstand voltage tester for an ozone generator, a dust cover is horizontally mounted directly above the main body of the tester. Several insulating rods are symmetrically fixed to the bottom of the dust cover in a cross shape. The bottom ends of each insulating rod extend into the inner wall of a U-shaped housing and slide in a damping engagement with it. This provides dust protection for the main body of the tester.

[0008] According to the aforementioned withstand voltage tester for an ozone generator, a layer of fire-resistant and non-slip cloth is laid on the top surface of the second insulating pad. This facilitates stable and non-slip placement of the device under test and prevents the risk of fire.

[0009] According to the aforementioned withstand voltage tester for an ozone generator, a handle is fixedly connected to the upper middle part of the front side of the L-shaped cover, and a pull handle is fixedly connected to the center of the front side of the storage box. Both the handle and the pull handle are covered with insulating sleeves. This facilitates stable operation of the L-shaped cover and the storage box for cable securing and storage.
