[0001] This utility model relates to a voltage flow monitoring instrument for electrical equipment, belonging to the field of electrical equipment technology. Background Technology

[0002] A voltage monitor is an instrument used to continuously monitor, statistically analyze, and report voltage changes. In related technologies, a voltage monitor is usually connected in parallel with the live wire and neutral wire in a household circuit. The main power is turned off, the live wire is passed through the wiring slot and a knob is used to press the live wire to the input terminal of the voltage monitor, and the neutral wire is passed through the wiring slot and a knob is used to press the neutral wire to the output terminal of the voltage monitor. The main power is then turned on, thereby monitoring voltage changes.

[0003] Patent CN209728001U discloses a voltage monitor that is easy to connect, including an upper housing, a lower housing, and two symmetrical snap-fit ​​components connecting the upper and lower housings. The two snap-fit ​​components are respectively connected to the inner sidewalls at both ends of the upper housing. Each snap-fit ​​component includes a connecting rod connected to the inner sidewall of the upper housing. The other end of the connecting rod is connected to a snap-fit ​​box, and a sliding rod is connected to the inner sidewall of the snap-fit ​​box. Two symmetrical sliding plates are slidably fitted onto the sliding rod. However, the following shortcomings occur during use: Existing voltage flow monitors generally install protective plates to protect the terminals, but the protective covers and terminals are mostly fixed with screws, which is inconvenient to use and also prevents cleaning of dust at the terminals, easily causing poor contact between the terminals and the voltage flow monitor. Summary of the Invention

[0006] The cleaning unit includes a cleaning plate, which is fixed to the inner side of the protective cover, and a cleaning brush is provided on the side of the cleaning plate.

[0007] The cleaning brush is a silicone brush.

[0008] Two sliding grooves are opened on the side of the voltage flow detection body. The sliding grooves are symmetrically arranged on the outside of the mounting groove. Sliding rods are symmetrically arranged on the inner side of the protective cover plate, and the sliding rods are arranged in the corresponding sliding grooves.

[0009] An operating groove is provided on the outer side of the protective cover, and a protrusion is provided in the operating groove.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the voltage flow monitor for electrical equipment has a protective cover that is easy to install and remove. When the protective cover covers the mounting slot, it protects the wiring terminals. When the protective cover is opened, the cleaning brush cleans the dust from the wiring terminals, improving the contact effect between the wiring terminals and the voltage flow monitor.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-4As shown, a voltage flow monitoring instrument for electrical equipment in this embodiment includes a voltage flow monitoring instrument body 1. A mounting groove 3 is formed on the side of the voltage flow monitoring instrument body 1, and three wiring terminals 4 are installed in the mounting groove 3. Two vertically arranged sliding grooves 7 are formed on the side of the voltage flow monitoring instrument body 1, symmetrically arranged on both sides of the mounting groove 3. A protective cover plate 5 is installed over the mounting groove 3. Two horizontally arranged sliding rods 6 are symmetrically arranged on the inner side of the protective cover plate 5. The sliding rods 6 are located in the corresponding sliding grooves 7 and can move up and down within the sliding grooves 7, causing the protective cover plate 5 to move up and down, allowing the protective cover plate 5 to switch between closing and opening the mounting groove 3. A sealing strip 10 is provided at the top of the protective cover plate 5, the length of which corresponds to the length of the protective cover plate 5, sealing the top of the mounting groove 3. A fixing baffle 2 is provided on the side of the voltage flow monitoring instrument body 1, and a docking groove 11 is formed at the bottom of the fixing baffle 2, located above the sealing strip 10. A long first magnet 12 is provided at the top of the sealing strip 10, and a long second magnet 13 is provided in the mating groove 11, with the first magnet 12 and the second magnet 13 corresponding to each other. An operating groove 14 is opened on the outer side of the protective cover 5, and multiple evenly distributed protrusions are provided in the operating groove 14 to facilitate the movement of the protective cover. When wiring is required, the finger is held by the protrusion and pulled down, and the sliding rod slides down in the sliding groove, causing the protective cover to move down and expose the wiring terminals in the mounting groove, and then wiring is performed; after wiring is completed, the finger is held by the protrusion and pulled up, and the sliding rod slides up in the sliding groove, causing the sealing strip and the first magnet to move up, so that the sealing strip seals the top of the mounting groove, and the first magnet moves into the mating groove and attracts the second magnet in the mating groove, thereby fixing the protective cover to the side of the voltage flow monitor body, thus protecting the wiring terminals and avoiding the need for screws to disassemble and install the protective cover, making the disassembly and installation of the protective cover more convenient and quick.

[0018] The sliding rod and the sliding groove work together to guide the movement of the protective cover.

[0019] A continuous cleaning plate 8 is provided on the inner side of the protective cover 5, and a cleaning brush 9 is provided on the side of the cleaning plate 8. The length of the cleaning brush 9 is greater than the distance between the first and last terminals. As the protective cover moves up and down, it drives the cleaning brush to move up and down, so that the cleaning brush can clean the dust on the terminals and improve the contact effect between the terminals and the voltage flow detector.

[0020] The cleaning brush mentioned above is a silicone brush.

[0021] The protective cover of this application is easy to install and remove. When the protective cover is installed over the mounting slot, it protects the wiring terminals. When the protective cover is opened over the mounting slot, the cleaning brush cleans the dust from the wiring terminals, improving the contact effect between the wiring points and the voltage flow detector.

[0022] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
