[Hardware architecture of ceiling-mounted network switching equipment]

Please refer to Figures 1 to 4. Figure 1 is a schematic diagram of ceiling-mounted network switching equipment provided by this embodiment of the invention. Figure 2 is a schematic diagram of the storage of ceiling-mounted network switching equipment provided by this embodiment of the invention. Figure 3 is a schematic diagram of the ceiling-mounted network switching equipment provided by this invention. The embodiment provides a schematic diagram of a ceiling-mounted network switching device from another angle, as shown in Figure 4 An exploded schematic diagram of a cover plate of a ceiling-mounted network switching device is provided for this creative embodiment.

In one implementation, the ceiling-mounted network switching device 1 (hereinafter referred to as the network switching device for convenience of explanation) includes, but is not limited to, a casing 10, a support portion 12, a network transmission interface 14, a DC output interface 16, and a lamp. No. 18 interface and control module 2. The support portion 12 is provided around the housing 10 . The support portion 12 can provide support to the housing 10 . For example, the housing 10 can be detachably mounted on a plane through the support portion 12 . The network transmission interface 14 and the DC output interface 16 are disposed on one plane of the casing 10 (for example, the top surface of the casing), and the light signal interface 18 is disposed on another plane of the casing 10 (for example, the bottom surface of the casing). The control module 2 is disposed inside the housing 10 and is electrically connected to the network transmission interface 14, the DC output interface 16 and the light signal interface 18 respectively. The control module 2 here serves as the main control core of the network switching device 1, for example It can control the network data transmission, DC power supply and peripheral devices of the network switching equipment 1.

Furthermore, in order to effectively fix the network switching device 1 on a flat surface, the support part 12 here includes multiple sets of rotating parts 120. These rotating parts 120 are, for example, provided on the side surfaces of the housing 10. . The outer shape of the housing 10 is illustrated as a circular cup. The rotating parts 120 can be equidistantly distributed through a certain number of side surfaces of the circular cup. The number of rotating parts 120 provided here is, for example, three groups. It should be noted that the number and position of the rotating parts 120 and the appearance shape of the housing 10 are only examples and are not intended to limit the invention.

As shown in FIGS. 1 and 2 , the rotating part 120 includes, for example, but is not limited to, a rotating rod 121 , a rotating arm 123 , a fixing groove 125 and a receiving groove 127 . The storage groove 127 and the fixing groove 125 are respectively formed on the outer surface of the housing 10 and are arranged adjacently, and the rotating rod 121 is fixedly arranged in the fixing groove 125, and the rotating arm 123 is screwed on the rotating rod 121, where the rotating rod 121 can perform axial rotation in the fixing groove 125 according to an external force input operation, for example, the external force input operation is directly applied to the working surface of one end of the rotating rod 121 (such as the bottom surface of the housing 10) through a screwdriver tool.

Thereby, the rotating arm 123 can also drive the rotating arm 121 when the rotating rod 121 itself rotates. The rotating arm 123 moves on the rotating rod. For example, when the rotating rod 121 rotates in a first rotation direction (eg, clockwise direction) according to an external force input operation, the rotating arm 123 can move along a first direction of the rotating rod 121 . And when the rotating rod 121 rotates in the second rotation direction (for example, counterclockwise direction) according to the external force input operation, the rotating arm 123 can move along a second direction of the rotating rod 121. The first direction and the second direction are opposite directions.

Furthermore, when the rotating rod 121 rotates, if the position where the rotating arm 123 and the rotating rod 121 are screwed is located in the fixing groove 125 instead of the receiving groove 127, the rotating arm 123 is limited by the two sides of the fixing groove 125.

When the rotating arm 123 is screwed into the fixing groove 125, the rotating arm 123 protrudes from the outer surface of the housing, as shown in FIG. 1 .

It is worth noting that when the support part 12 wants to provide support for the housing 10 on a flat surface, the rotating arm 123 must be protruded from the outside of the housing 10. That is, the rotating rod 121 is operated by external force to drive the rotating arm 123 to move into position. in the area of the fixing groove 125 . On the contrary, when the support part 12 does not need to provide support to the housing 10, the rotating rod 121 can be selectively operated through external force to drive the rotating arm 123 to move to the area of the storage slot 127. At this time, the rotating arm 123 is retracted in the storage slot 127. in slot 127.

In one embodiment, the rotating rod 121 may be a screw, and the rotating arm 123 may have a screw hole. The rotating arm 123 and the screw are screwed to each other through the screw hole.

As shown in Figure 3, when the cover plate 3 is buckled on the bottom side of the housing 10, the cover plate 3 has an indication hole 31. Through the indication hole 31 Can It is used to display some light status in the light interface 18. In addition, as shown in Figure 4, the cover 3 can also be separated from the housing 10. At this time, all the light status of the light interface 18 of the housing 10 can be fully displayed, so that personnel can know the current status through the light interface 18.
