[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a highly protective three-phase ammeter, comprising:

[0025] The three-phase ammeter body 1 and the guide frames 2 installed on both sides of the three-phase ammeter body 1. A protective structure is slidably installed on the three-phase ammeter body 1 through two sets of guide frames 2, and the functional parts of the three-phase ammeter are protected by the protective structure.

[0026] The protective structure includes a display screen protection component 3 for protecting the display screen on the three-phase ammeter body 1 and a control button protection component 4 for protecting the operation buttons on the three-phase ammeter body 1. The control button protection component 4 is rotatably installed below the display screen protection component 3.

[0027] The display screen protection component 3 includes a protective cover 31. Two sets of sliders 5 are fixedly connected to both sides of the protective cover 31 and slide within the guide frame 2. The top view of the two sets of sliders 5 is convex. A first transparent plate 32 for viewing the display screen values ​​is provided on one side of the protective cover 31. The two sets of sliders 5 facilitate the flipping of the protective cover 31 outside the three-phase ammeter body 1, thereby opening and closing the display screen protection component 3. The first transparent plate 32 facilitates viewing the display screen without opening the protective cover 31, improving the convenience of viewing the values.

[0028] A top cover 33 is fixedly connected to the top of the protective cover 31. A buffer rubber beam 34 that fits against the top of the three-phase ammeter body 1 is fixedly connected to the lower surface of the top cover 33. A toggle block 37 is fixedly connected to the top of one side of the protective cover 31. The toggle block 37 facilitates the opening and closing of the protective cover 31. At the same time, the buffer rubber beam 34 can reduce the pressure of the protective structure on the three-phase ammeter body 1, thereby preventing damage to the top of the three-phase ammeter body 1.

[0029] The control button protection assembly 4 includes a lower protective cover 41 that is rotatably mounted on the lower end of one side of the upper protective cover 31. A second transparent plate 42 is provided on one side of the lower protective cover 41, and two sets of reinforcing beams 45 are fixedly connected to the other side of the lower protective cover 41. The lower protective cover 41 provides convenient protection for the button area of ​​the three-phase ammeter body 1, and is dustproof and waterproof when the button area is not in use, thus avoiding damage to the button area. The reinforcing beams 45 improve the overall strength and service life of the lower protective cover 41.

[0030] Both sets of reinforcing beams 45 are fixedly connected to the top of a locking block 44. The lower end of the protective cover 41 is provided with a slot 35 for the two sets of locking blocks 44 to be inserted. Two sets of first magnets 36 are embedded on one side of the protective cover 31, and a second magnet 43 that is magnetically attracted to the two sets of first magnets 36 is embedded on one side of the protective cover 41. The locking block 44 and the slot 35 facilitate the locking of the protective cover 41 and the protective cover 31, thereby facilitating the opening and closing of the whole. At the same time, when the first magnet 36 and the second magnet 43 are magnetically attracted, it is convenient to open the control button protection component 4 when the display screen protection component 3 is not open, so as to operate the button area separately, thereby improving practicality.

[0031] The inner wall of the guide frame 2 is provided with a limiting inner groove 21 for the slider 5 to slide. The guide frame 2 is mainly made of a vertical limiting frame 22, a turning guide frame 23 and a horizontal limiting frame 24 integrally formed. The inner groove can limit the slider 5 and prevent the slider 5 from leaving the limiting inner groove 21. At the same time, it is convenient to guide the slider 5 and flip the protective structure so that the protective structure can be opened and closed, which improves the ease of use.

[0032] The vertical limiting frame 22 and the horizontal limiting frame 24 are set vertically. The steering guide frame 23 is a semi-circular frame. The distance between the two sets of sliders 5 is greater than the radius of the steering guide frame 23. When both sets of sliders 5 are located within the vertical limiting frame 22, it is a protective structure protecting the three-phase ammeter body 1. When both sets of sliders 5 are located within the horizontal limiting frame 24, the display area of ​​the three-phase ammeter body 1 is exposed.

[0033] In use, in the initial state, the slider 5 is located in the vertical limit frame 22. At this time, the protective upper cover 31 and the protective lower cover 41 completely cover the three-phase ammeter body 1. The buffer rubber beam 34 under the top cover 33 reduces the pressure of the protective structure on the top of the meter. The protective lower cover 41 is firmly connected to the protective upper cover 31 through the card slot 35 via the card block 44, together providing dustproof and waterproof protection for the display screen and operation buttons.

[0034] When it is necessary to view the values, the user can directly read the values ​​on the display screen through the first transparent plate 32. If it is necessary to operate the buttons, the user can move the protective lower cover 41 to disengage the card block 44 from the card slot 35. The user can then use the magnetic attraction between the first magnet 36 and the second magnet 43 to rotate and open the protective lower cover 41 to operate the control buttons on the three-phase ammeter. After the operation is completed, the user can close and lock the protective lower cover 41 to restore the full protection state.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
