[0021] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0022] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0024] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0025] The utility model provides a rotary DC monitor, such as Figure 1 and Figure 2 As shown, the monitor body 10 is provided with a rotating cover 20 on the outside of the monitor body 10, wherein slide grooves 11 are symmetrically opened on the opposite sides of the monitor body 10, and a rotating shaft 21 is provided at the position of the rotating cover 20 corresponding to the slide groove 11, wherein the rotating shaft 21 can rotate and slide in the corresponding slide groove 11.

[0026] When the rotating cover 20 is mounted on the monitor body 10 , the rotating shaft 21 is located in the slide groove 11 . At this time, the rotating cover 20 can be rotated within a certain angle, which makes it convenient to inspect and maintain the monitor body 10 .

[0027] In order to ensure that the rotating cover 20 is installed more stably on the monitor body 10, a first positioning hole 12 is provided on the side of the monitor body 10 on one side of the slide groove 11, and a positioning column 22 is provided at the position of the rotating cover 20 corresponding to the first positioning hole 12. The positioning column 22 cooperates with the first positioning hole 12, and the slide groove 11 and the first positioning hole 12 are used to limit the two ends of the rotating cover 20, thereby ensuring that the rotating cover 20 can be stably installed on the monitor body 10.

[0028] When the rotating cover 20 needs to be rotated, the rotating shaft 21 is used as the rotation center, and the positioning column 22 will slide out from the first positioning hole 12, so that the rotating cover 20 can rotate smoothly, facilitating subsequent work.

[0029] Specifically, in this embodiment, the rotating cover 20 needs to be rotated upward, that is, the rotating cover 20 is rotated in the direction away from the monitor body 10. At this time, the rotating cover 20 opens a certain space, which is convenient for functional testing and maintenance of the monitor body 10. In order to make the rotating cover 20 still stable after opening to a certain extent, a second positioning hole 13 is provided on one side of the first positioning hole 12. When the rotating cover 20 is opened to a certain angle, the positioning column 22 moves out of the first positioning hole 12 and then enters the second positioning hole 13. At this time, the rotating cover 20 can be stably opened, which is more convenient for testing and maintenance.

[0030] The first positioning hole 12 and the second positioning hole 13 are close to the connection point of the monitor body 10 .

[0031] A wire outlet slot 23 is provided on the side of the rotating cover 20 , and the wiring of the monitor body 20 is connected out through the wire outlet slot 23 . At the same time, a wire clamping slot 14 is installed on the monitor body 10 to ensure that the wiring of the monitor body 10 is more neat.

[0032] During normal operation, in order to ensure that the rotating cover 20 is more stably mounted on the monitor body 10 and prevent theft, a lead sealing hole 24 is provided on the rotating cover 20, and a lead sealing column 15 is provided at a position corresponding to the lead sealing hole 24 on the monitor body 10. A lead sealing screw 25 is provided in the lead sealing hole 24, and the lead sealing screw 25 is threadedly connected to the lead sealing column 15. A lead sealing buckle 26 is covered on the lead sealing screw 25 in the lead sealing hole 24.

[0033] In this embodiment, the lead sealing hole 24 can be opened on the top surface and / or the side surface of the rotating cover 20, which can be selected according to actual conditions.

[0034] At the same time, when the monitor body 10 is inspected and maintained, in order to accurately know the number of times the rotating cover 20 is opened to facilitate subsequent statistics and inspections, the monitor body 10 is provided with a button hole 16, and a button handle 27 is installed at a position corresponding to the button hole 16 on the rotating cover 20, wherein a counter is provided in the button hole 16.

[0035] like Figure 3 As shown, when inspection and testing are required, the lead sealing screw 25 is removed, the positioning column 22 on the rotating cover 20 is located on the first positioning hole 12, the button handle 27 is inserted into the button hole 16, and acts on the counter. When the rotating cover 20 is rotated, the positioning column 22 moves to the second positioning hole 13. At this time, the button handle 27 slowly moves out of the button hole 16, thereby separating from the counter. At this time, the counter counts once. After the inspection is completed, the positioning column 22 is moved to the first positioning hole 12 again, and the button handle 27 is pressed on the counter again. If the rotating cover 20 is opened again later, the counter counts again. The number of times the rotating cover 20 is opened can be known through the counter. By recording, it can be known whether anyone has opened the rotating cover 20 privately, which has a certain monitoring effect.

[0036] It should be understood that the above description of the specific embodiments of the present invention is merely for the purpose of illustrating the technical approach and features of the present invention. Its purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. However, the present invention is not limited to the above-described specific embodiments. Any changes or modifications made within the scope of the claims of the present invention shall be included within the scope of protection of the present invention.
