Description

Technical Field

[0001] The utility model relates to the field of gateways, in particular to a data acquisition gateway. Background Art

[0002] Gateway is also called network connector or protocol converter. Gateway realizes network interconnection above the network layer. It is a complex network interconnection device and is only used for interconnection between two networks with different high-level protocols. Gateway can be used for wide area network interconnection as well as local area network interconnection. Gateway is a computer system or device that performs the important task of conversion. It is used between two systems with different communication protocols, data formats or languages, or even completely different architectures. Gateway is a translator. Unlike a bridge that simply transmits information, a gateway repackages the received information to meet the needs of the destination system. Same layer - application layer.

[0003] A data acquisition gateway is a device or software system used to connect, collect, process and transmit information from different data sources (such as sensors, metering equipment, control systems, etc.).

[0004] In the prior art, a data acquisition gateway is provided with a plurality of interfaces for connecting with other devices. However, in the actual use of the data acquisition gateway, not all of these interfaces are required to be used, so that some interfaces are idle. However, due to the lack of corresponding protective measures, the interfaces in the idle state are exposed to the external environment, and dust in the air is easily attached and accumulated in the interfaces, which makes it easy for the data acquisition gateway to have poor contact when connected to the network cable through the interface, affecting the transmission of signals between devices, and further affecting the normal use of the data acquisition gateway.

The short threaded rods 4 arranged above the rear end interface 2 of the gateway body 1 are used to cooperate with the installation of the protection mechanism 3;

[0023] like Figure 4As shown, mounting plates 6 are fixedly mounted on the left and right side walls of the fixing plate 5, respectively, and a group of symmetrical mounting holes 7 are opened on the front end wall of the mounting plate 6, the threaded short rods 4 are inserted and installed in the mounting holes 7, and the nuts 8 are threadedly connected with the threaded short rods 4. Before use, the gateway body 1 pre-installs the fixing plate 5 on the rear end wall of the gateway body 1. During installation, the threaded short rods 4 are passed through the mounting holes 7 opened on the front end walls of the mounting plates 6 on both sides of the fixing plate 5, and the nuts 8 are screwed into the threaded short rods 4 and threadedly connected with them, so that the fixing plate 5 can be installed on the rear end wall of the gateway body 1;

[0024] like Figure 4 As shown, a plurality of grooves 9 corresponding to the interface 2 are provided on the rear end wall of the fixed plate 5, and slide grooves 10 are provided on both sides of the inner wall of the groove 9, and a movable opening 11 connected to the groove 9 is also provided on the front end wall of the fixed plate 5. The groove 9 and the slide grooves 10 on both sides of the groove 9 enable the slide bar 16 to slide in the slide groove 10 to drive the movable plate 14 to move in the groove 9, and the movable opening 11 is provided so that the push plate 17 can drive the movable plate 14 to move after moving in the movable opening 11;

[0025] like Figure 4 As shown, the fixing rod 12 is fixedly mounted on the top surface of the groove 9, and a compression spring 13 is sleeved on the outside of the fixing rod 12, and the top of the compression spring 13 is fixedly mounted on the top surface of the groove 9. The fixing rod 12 arranged in the groove 9 allows the movable plate 14 to move in the groove 9 along the fixing rod 12 through the connecting hole 15, and when the interface 2 is in use, the compression spring 13 will be in a compressed state, and when the interface 2 is in an idle state, the compression spring 13 will be in a normal extended state;

[0026] like Figure 4As shown, a connecting hole 15 is provided on the top surface of the movable plate 14 and is sleeved on the fixed rod 12 through the connecting hole 15, and the movable plate 14 is also fixedly installed on the bottom end of the compression spring 13, and slide bars 16 are fixedly installed on the two side walls of the movable plate 14, and the slide bars 16 are movably installed in the slide groove 10, and a push plate 17 passing through the movable opening 11 is fixedly installed on the bottom of the front end wall of the movable plate 14, and a baffle 18 is also fixedly installed on the bottom surface of the movable plate 14, and a rubber sheet 19 close to the front end of the interface 2 is fixedly installed on the rear end wall of the baffle 18. When the compression spring 13 is in the positive position, the movable plate 14 is in the positive position. When the movable plate 14 is in a normal elastic stretching state, the movable plate 14 will be moved downward under the action of elasticity, so that the baffle 18 on the bottom surface of the movable plate 14 is blocked in front of the interface 2, and the rubber sheet 19 on the rear end wall of the baffle 18 will be in close contact with the interface 2 and shield and seal the interface 2, which can prevent the interface 2 from being exposed to the external environment and prevent dust from entering the interface 2 to affect the use of the gateway body 1, thereby playing an effective dust-proof protection role for the interface 2 on the gateway body 1 when idle, thereby ensuring the normal use of the gateway body 1 and the interface 2 on the gateway body 1 in the subsequent use.

[0027] It should be noted that the utility model is a data acquisition gateway. The gateway body 1 pre-installs the protective mechanism 3 on the rear end wall of the gateway body 1 before use. During installation, the threaded short rod 4 on the rear end wall of the gateway body 1 is inserted into the mounting hole 7 opened on the front end wall of the mounting plates 6 on both sides of the fixing plate 5, and the nut 8 is screwed into the threaded short rod 4 and threadedly connected with it. In this way, the fixing plate 5 can be quickly installed on the rear end wall of the gateway body 1. At this time, the compression spring 13 outside the fixing rod 12 on the top surface of the groove 9 in the rear end wall of the fixing plate 5 will be in an extension operation and will continue to push downward under the elastic extension force. The movable plate 14 is moved, and the two side slide bars 16 of the movable plate 14 are in the slide groove 10, so the movable plate 14 will not move out of the groove 9, so that the baffle 18 installed on the bottom surface of the movable plate 14 will block the front of the interface 2, and the rubber sheet 19 on the rear end wall of the baffle 18 will be tightly attached to the front end wall of the interface 2, so as to shield and seal the interface 2, avoid the interface 2 from being exposed to the external environment when not in use, and prevent dust from entering the interface 2, so as to effectively prevent the interface 2 on the gateway body 1 from being idle and dust protection, thereby ensuring the normal use of the gateway body 1 and the interface 2 on the gateway body 1 in the subsequent use;

[0028] When the interface 2 needs to be used, the push plate 17 can be manually pushed upward, and the push plate 17 will move upward in the movable opening 11 opened at the front end of the fixed plate 5, and drive the movable plate 14 to move upward in the groove 9, and the movable plate 14 will move in the groove 9 along the fixed rod 12 through the connecting hole 15 opened on the top surface, and the slide bars 16 on both sides of the movable plate 14 will slide in the slide groove 10, and force the compression spring 13 set on the outside of the fixed rod 12 to retract, until the baffle 18 installed on the bottom surface of the movable plate 14 completely enters the groove 9, thereby, The interface 2 that needs to be used can be exposed to facilitate the connection of the connecting wire to the interface 2. Furthermore, when the connecting wire is unplugged from the interface 2, the compression spring 13 will restore the extension operation and push the movable plate 14 under the elastic force.
