Description

Technical Field

[0001] The present application relates to the field of industrial control, and in particular to an industrial control device that is easy to install a board. Background Art

[0002] Industrial control equipment, also known as industrial computers, is a general term for tools that detect and control production processes, electromechanical equipment, and process equipment. An industrial control box is generally equipped with components such as a baseboard, power supply, fan, hard disk, and graphics card. Various boards are also plugged into the baseboard for signal transmission.

[0003] At present, in order to meet more signal transmission functions, additional expansion slots are usually set on the chassis of industrial computers to meet the needs of different scenarios. When it is necessary to increase the signal transmission path, the expansion board is usually plugged into the card slot on the baseboard to achieve the purpose of increasing the signal transmission path.

[0004] However, when the expansion slot on the traditional chassis is not in use, a baffle is usually fixed at the slot position of the expansion slot to achieve dust sealing. When a board needs to be added to the bottom plate, the baffle must be removed first, and then the board is plugged into the bottom plate. A metal baffle is usually set on the board, and a through hole is usually set on the metal baffle. Then, the metal baffle is fixed to the inner wall of the chassis through the through hole with bolts to fix the board. However, this operation method is more cumbersome and cannot quickly realize the expansion installation of the board, making the installation efficiency of the board low. Summary of the invention

[0055] The working principle of the embodiment of the present application is as follows: when it is necessary to add a board, the unlocking rod 555 is pressed into the unlocking slot 18, so that the unlocking rod 555 compresses the unlocking spring 557, and the push block 558 pushes the baffle 559, so that the baffle 559 is separated from the locking block 5511, so that the baffle 559 is rotated away from the unlocking block 556 under the action of the third torsion spring 5510, thereby opening the expansion port 12, and then the unlocking rod 555 is released, so that the unlocking rod 555 slides back to its original position in the direction away from the unlocking slot 18 under the action of the unlocking spring 557. Then, the board is inserted into the slot on the base plate 2, so that the metal baffle on the board presses down the limit column 551 and compresses the limit spring 553. At the same time, the guide rod on the limit column 551 slides along the guide groove 16, thereby driving the limit column 551 to rotate, so that the limit plate 552 is separated from the control plate 554, so that the positioning plate 51 drives the positioning column 52 to rotate downward under the action of the first torsion spring 53, so that the positioning column 52 passes through the hole of the board and is inserted into the positioning groove 14, thereby realizing the positioning of the board.

[0056] When the board needs to be removed, the unlocking rod 555 is first pressed so that the unlocking block 556 on the unlocking rod 555 pushes the control board 554 upward, thereby driving the positioning plate 51 to rotate away from the positioning slot 14 through the rotating column 54, so that the positioning column 52 releases the positioning of the board. When the control board 554 rotates to a horizontal state, the positioning plate 51 is located in the vertical direction. At this time, the board is pulled out, so that the metal baffle on the board is separated from the limiting column 551, so that the limiting column 551 moves upward and resets under the action of the limiting spring 553, and slides in the guide slot 16 through the guide rod, thereby rotating, so that the limiting plate 552 rotates to the bottom of the control board 554, thereby supporting the control board 554, so that the positioning plate 51 remains in the vertical direction, which is convenient for installing a new board. Then release the unlocking rod 555, and after the unlocking rod 555 is reset under the action of the unlocking spring 557, push the baffle 559 to rotate, so that the locking groove 5513 on the baffle 559 is engaged with the locking block 5511, thereby positioning the baffle 559 and achieving sealing of the expansion port 12.
