Description

Technical Field

[0001] The utility model relates to the technical field of network engineering, in particular to a novel network switch. Background Art

[0002] The main functions of a switch are physical addressing, network topology, error checking, frame sequence, and flow control. A switch is a network device used for forwarding electrical and optical signals. It also has some new functions such as support for virtual LANs, support for link aggregation, and even some have firewall functions.

[0003] When the switch receives a data packet from one of its ports, it first reads the source MAC address in the packet header (that is, the MAC address of the network card of the device that sent the packet), matches the MAC address and the port and adds it to the address table in the switch memory; then it reads the destination MAC address in the packet header, and compares it with the address table in the memory to see which port the MAC address corresponds to. If there is a corresponding port for the MAC address in the address table, the packet is directly copied to the corresponding port. If not found, the data frame is sent to all ports as a broadcast frame, and the corresponding MAC address device will automatically accept the frame data. At the same time, the switch matches the port that receives the frame data with the destination MAC address and puts it into the address table in the memory;

[0004] In the prior art, switches are always placed in high places such as brackets and cabinet tops, and there is no way to fix them. The switches are easily touched by mistake, or the cables are pulled by other reasons, causing the switches to fall, which can easily cause the switches to fall and be damaged, and unable to work normally. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of network switch to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a new network switch, comprising:

[0007] A connecting cylinder, on the surface of which two groups of telescopic columns are arranged, and the telescopic columns are symmetrically distributed on the surface of the connecting cylinder;

[0008] A connecting drum, the surface of which is provided with two groups of limiting circular holes, and the surface of which is provided with a limiting circular ring;

[0009] The base has a rotating drum base on the top and double-sided adhesive tape on the bottom.

[0010] Preferably, a connecting disc is welded on the top of the connecting cylinder, the connecting disc is welded to the switch body, and a plurality of heat dissipation grooves are provided at the bottom of the switch body, and the heat dissipation grooves are square.

[0011] Preferably, a fixing plate is provided inside the connecting cylinder, the fixing plate is welded to the compression spring, the compression spring is welded to the arc plate, the arc plate is welded to the telescopic column, and the arc plate can fit with the inner wall of the connecting cylinder.

[0012] Preferably, the inner diameter of the connecting drum is larger than the outer diameter of the connecting cylinder, a plurality of groups of convex bodies are provided on the surface of the connecting drum, a groove is provided inside the limiting ring, and the limiting ring slides along the convex bodies.

[0013] Preferably, the surface of the limiting circular ring is provided with a plurality of groups of limiting square columns, and the surface of the drum base is provided with a plurality of groups of limiting square grooves.

[0014] Preferably, the length of the connecting cylinder is the same as that of the connecting drum, the interior of the connecting cylinder is half solid and half hollow, and the interior of the connecting drum is hollow.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model discloses a novel network switch, wherein the base is fixed to a height such as the cabinet top or the bracket top by double-sided adhesive, and then the switch body with the connecting cylinder is plugged into the connecting rotating drum. When plugging, the telescopic column is pressed by fingers so that the connecting cylinder can enter the inside of the connecting rotating drum. When it reaches the bottom, the telescopic column automatically extends out of the limiting circular hole under the elastic force of the compression spring, so as to fix the switch body. The existence of the connecting rotating drum can change the direction of the switch body, and the cables in different directions can be plugged in. When changing the direction, it is only necessary to pull the limiting circular ring upward, and the connecting rotating drum can be rotated at this time. After the hand is released, the limiting square column falls into the limiting square groove, and at this time the connecting rotating drum is fixed, and the switch body is also fixed. Since there is a certain space between the switch body and the base, the heat dissipation groove exists at the bottom of the switch body, and the bottom can have a good heat dissipation effect. In addition, it can also effectively prevent the entry of dust. The switch body can also be disassembled for easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
