Description

Technical Field

[0001] The utility model relates to the technical field of mining switches, in particular to a mining three-layer gigabit switch. Background Art

[0002] The safe production of coal mines requires the establishment of a coal mine underground safety detection and monitoring system to form a reliable safety warning mechanism and management decision-making information channel above and below the mine. The mine safety detection system can accurately monitor the safety production information above and below the mine at all times through data management and remote monitoring, thereby preventing various accidents. The coal mine safety detection system has become an indispensable detection system for coal mine production. During the underground construction of this system, a mine switch is required to achieve network access.

[0003] According to a mining switch disclosed in Chinese patent number CN219181546U, the mining switch includes a mining switch, a cabinet door, and a placement plate. The utility model sets the mining switch, the cabinet door, the placement plate, the housing, the positioning mechanism, and the control mechanism for coordinated use. By pushing the control block toward the side close to the mining switch, the control block drives the control mechanism to cooperate with the positioning mechanism to make the positioning rod in the positioning mechanism leave the inside of the card slot, and then aligns the position between the card slot and the card block, and installs the mining switch on the front side of the placement plate, and then positions it through the positioning mechanism, which solves the problem that the existing mining switch needs to be installed on the placement plate when it is used. However, the existing installation method is usually fixed with screws, and the user must use tools. It is difficult for the user to install without tools, which greatly wastes the user's time and energy, thereby reducing the practicality of the mining switch.

[0004] The above-mentioned comparative documents and prior art have the following problems:

[0005] 1. At present, many mining switches have a limited number of ports, which makes it easy for the number of ports to be insufficient. It is not convenient to increase the number of ports to adapt to the communication and transmission of various data. In addition, due to the harsh environment underground in coal mines, unused ports cannot be effectively protected, and the practicality is low. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a three-layer gigabit switch for mining.

[0008] Preferably, the reinforcement assembly consists of a support plate, a damping rod, a spring and a fixed block, the surface of the support plate is provided with a damping rod, the surface of the damping rod is provided with a spring, and the end of the damping rod is provided with a fixed block.

[0009] Preferably, a box cover is provided on the surface of the box body, and a handle is provided on the side of the box body.

[0010] Preferably, the grooves are arranged in a linear array on the surface of the protective shell, and the shapes of the grooves are respectively adapted to the movable block and the second port.

[0011] Preferably, the first port is electrically connected to the switch body, and the first contact is electrically connected to the switch body.

[0012] Preferably, the side surface of the movable block is engaged with the side surface of the second port, and the shape of the movable block is matched with the movable groove.

[0013] Preferably, the bottom surface of the fixed block is an inclined surface, and the shape of the fixed block is matched with that of the movable block.

[0014] Beneficial Effects

[0015] In the utility model, a protective shell, a movable block, a second port, a first contact and a second contact are adopted. When the number of the first ports is insufficient for use, the movable block is slid into the movable groove, thereby driving the movable block to slide on the slide groove, thereby driving the second port to slide on the slide groove, so that the second port is exposed from the groove. At the same time, the second contact contacts the first contact to establish an electrical connection, so that the second port is electrically connected to the switch body, thereby increasing the number of the second ports. At the same time, since the unused second ports are arranged inside the protective shell, they are effectively protected, and the utility model is relatively strong.
