Description

Technical Field

[0001] The utility model belongs to the technical field of electroscope equipment, and in particular relates to an acousto-optic rod type electroscope. Background Art

[0002] An acousto-optic electroscope is a safety testing tool used to detect whether electrical equipment or lines are energized. It combines audible and visual warnings, providing clear audio-visual feedback when voltage is detected, improving operator safety and work efficiency. However, existing electroscopes are difficult to place and lack adjustable length, making it difficult to maintain a safe distance between the operator and high-voltage live parts. They are also unsuitable for contact points at varying heights or depths, and can be damaged if dropped during operation, affecting normal use.

[0003] To address the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a telescopic, foldable acousto-optic electroscope [201510310100.9], which includes a mainboard box, a self-test button provided on the upper surface of the mainboard box; a speaker next to the self-test button; a signal indicator light above the speaker, which is also adjacent to the self-test button; a pure copper contact rod provided in front of the signal indicator light, located on the front side of the mainboard box; a foldable metal rod connected to the lower side of the mainboard box, located farther away from the contact rod; a telescopic insulating rod fixing sleeve connected to the lower side of the foldable metal rod; a telescopic insulating rod below the telescopic insulating rod fixing sleeve, and the two are in contact with each other; a rubber handle on the lower surface of the telescopic insulating rod, and the telescopic insulating rod is located inside the rubber handle, and the two are in precise contact.

[0004] The above solution solves the problem that the length of the existing electroscope cannot be adjusted to a certain extent, but the solution still has many shortcomings, such as the mainboard box being damaged when it falls or collides without protection. Summary of the Invention

The housing connection portion is axially disposed outside the housing block and extends into the interior of the fastening space. The housing block is inserted into the housing connection portion, which is located within the fastening collar. The housing connection portion is clamped by a fastening bolt to secure the housing connection portion to the housing block.

[0010] In the aforementioned acousto-optic rod electroscope, the protective assembly includes several power box protection plates disposed circumferentially outside the power box body, with several connecting ribs disposed between the power box protection plates and the power box body. The power box protection plates provide a cushioning effect for the power box body, preventing damage if the power box body is dropped.

Sealing grooves are provided on each of the four circumferential sides of the opening, each containing a sealing airbag. The sealing airbags, in conjunction with the sealing door, not only allow access to the interior of the built-in box but also ensure the sealing of the power supply box.

[0013] In the above-mentioned sound and light rod type electroscope, a movable block is rotatably provided at one end of the power supply box close to the light sensor, and the light sensor is connected to the power supply box through the movable block.

[0014] In the above-mentioned sound and light rod electroscope, the end face of one side of the power supply box having the opening has a rectangular frame, and one side of the sealing door is connected to one side of the rectangular frame through a hinge.

[0015] In the above-mentioned sound and light rod type electroscope, a notch is provided on the sealing door, and a handle is provided on the side of the sealing door away from the hinge.

[0016] Compared with the existing technology, the advantages of this utility model are:

[0017] 1. The device is equipped with a protective component on the outside of the power box to prevent damage to internal components due to falling. At the same time, a sealing groove and a sealing airbag are set inside the built-in box to cooperate with the sealing door to improve the sealing effect and prevent rainwater from entering and damaging the components.

[0018] 2. The device is equipped with a hook at the end of the telescopic rod, which is convenient for hanging and use, and will not be damaged by random placement. At the same time, the design of the telescopic rod can ensure that the operator maintains a safe distance from the high-voltage live parts, and it is also suitable for contact points of different heights and depths.
