[0022] Embodiment 1

[0023] Reference Figure 1 A digital display slip ring, including housing 1, the housing 1 is equipped with the monitoring component (not shown in drawing) for monitoring working parameter and environmental parameter, for example, install the monitoring component on the brush holder, and the monitoring component includes but is not limited to dynamic resistance meter, current sensor, temperature sensor, humidity sensor, and the housing 1 is equipped with the display screen 3 for displaying working parameter and environmental parameter, on this basis, the person skilled in the art should have the ability to electrically connect the monitoring component with the display screen 3, and the real-time detection result of the monitoring component is displayed through the display screen 3.

[0024] The shell 1 is provided with a mounting plane on one side, and the display cover plate 2 is connected to the mounting plane through a plurality of fasteners (such as screws). Further, a sealing gasket is arranged between the display cover plate 2 and the mounting plane to ensure the sealing between the display cover plate 2 and the shell 1. Alternatively, the outer surface of the display cover plate 2 of the embodiment is arc-shaped to form a cylinder with the shell 1, that is, the mounting plane is equivalent to cutting off part of the side of the shell 1, and the display cover plate 2 just makes up for this part, so as to avoid affecting the cylindrical shape of the shell 1. In addition, the inner surface of the display cover plate 2 of the embodiment is provided with an arc-shaped groove to reduce the weight of the display cover plate 2.

[0025] Reference Figures 2-5 The display cover plate 2 is provided with a mounting port 201 matching the size of the display screen 3, that is, the size of the display screen 3 matches the size of the mounting port 201. The mounting port 201 penetrates the thickness direction of the display cover plate 2 (that is, the mounting port 201 is in the form of a through hole), and a plurality of support pieces 202 are arranged in the mounting port 201. The display screen 3 is installed at the mounting port 201 and supported by the support pieces 202.

[0026] In the embodiment, the display screen 3 includes a screen body 301 and a frame 302 arranged on four axes of the screen body 301. It is worth noting that, on the basis that the inner and outer surfaces of the display cover plate 2 are arc-shaped, after the display screen 3 is placed in the mounting port 201, there will be a gap between the frame 302 and the side wall of the mounting port 201. Therefore, the two ends of the frame 302 of the embodiment are provided with protruding portions 3021 to close the gap between the frame 302 and the display cover plate 2, thereby playing a dustproof role. Further, the protruding portions 3021 have an arc surface flush with the surface of the display cover plate 2 to improve the aesthetics.

[0027] Alternatively, the frame 302 of the display screen 3 of the embodiment is fixed to the mounting port 201 by adhesion.

[0028] In the embodiment, the shell 1 is also provided with a mounting plane on the side symmetrical to the display cover plate 2, and the auxiliary cover plate 4 is connected to the mounting plane through a plurality of fasteners. In this way, both sides of the shell 1 can be opened, and subsequent maintenance is more convenient. On the basis of the above, it is easy to understand that a sealing gasket should also be arranged between the auxiliary cover plate 4 and the shell 1 to ensure the sealing. In addition, the auxiliary cover plate 4 is consistent with the display cover plate 2 in other structures except that the mounting port 201 is not arranged.

[0029] Embodiment 2

[0030] The difference between the embodiment and the embodiment 1 is the mounting method of the display screen 3. In the embodiment, the protruding portions 3021 are detachably connected to the display cover plate 2, so that the display screen 3 can be quickly disassembled and assembled. Specifically, the protruding portions 3021 on the frame 302 are connected to the display screen 3 through fasteners (such as screws).

[0031] Embodiment 3

[0032] The difference between the present embodiment and embodiment 2 is that the detachable connection manner of the display screen 3 is different, in the present embodiment, the two ends of the mounting port 201 are provided with spring plungers, and the convex part 3021 on the frame 302 is provided with a limiting groove matched with the spring plungers, and those skilled in the art should understand that the spring plunger is also called ball head plunger, which is usually provided with a spring in the column body, and the front end is usually in the form of a ball or a pin structure, after bearing the load, the ball or pin will sink into the main body, and after releasing the load, it will recover under the action of the spring.

[0033] On the basis of the above, when installing, only the display screen 3 is put into the mounting port 201, and the ball or pin at the front end of the spring plunger is clamped into the limiting groove under the action of the spring, so that the installation can be realized, when disassembling, after the display cover plate 2 is removed, the frame 302 is pushed outward, so that the ball or pin at the front end of the spring plunger sinks into the column body, so that the display screen 3 can be taken down, compared with embodiment 2, the disassembly and assembly of the display screen 3 is more convenient and fast.

[0034] The above is only the preferred embodiment of the present application, and is not used to limit the present application, for those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
