DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1-2 The present invention provides a technical solution: an intelligent heat dissipation PLC control cabinet, comprising a control cabinet 1 and support legs 3, the number of the support legs 3 is four groups, the four groups of support legs 3 are fixedly connected to the four corners of the bottom of the control cabinet 1, two groups of cabinet doors 2 are arranged on the back of the control cabinet 1, two groups of hinged rods 8 are fixedly connected to the left and right sides of the inner wall of the control cabinet 1, the four groups of hinged rods 8 are fixedly connected to the two groups of cabinet doors 2, a heat dissipation net 4 is installed on the front of the control cabinet 1, and a square hole 9 is opened inside the heat dissipation net 4, and also includes:

[0035] The pressing mechanism 5 includes a fixed block 503, the side of the fixed block 503 close to the cabinet door 2 is fixedly connected to the control cabinet 1, a dust cover 501 is arranged on the top of the fixed block 503, the side of the dust cover 501 close to the cabinet door 2 is fixedly connected to the control cabinet 1, a fitting block 512 is fixedly connected to the front of the fixed block 503, a pressing plate 505 is arranged on the side of the fitting block 512 away from the fixed block 503, a first pressing rod 506 and a second pressing rod 508 are rotatably connected to the side of the fitting block 512 close to the pressing plate 505 through a rotating shaft, and the left and right sides of the second pressing rod 508 are fixedly connected to a moving rod 509, and the moving direction of the moving rod 509 is controlled by pressing the heat dissipation net 4. The heat dissipation net 4 drives the moving rod 509 to push the rotating rod 511 so that it can quickly enter a fixed state. The two groups of moving rods 509 are fixedly connected to the rotating rod 511 on the side away from the second downward pressure rod 508. Two groups of limit blocks 510 are fixedly connected to the top of the inner wall of the dustproof shell 501. The two groups of limit blocks 510 are rotatably connected to the two groups of rotating rods 511 through a rotating shaft. The two groups of rotating rods 511 are fixedly connected to the pull rod 507 on the side away from the moving rod 509. The two groups of pull rods 507 are fixedly connected to the push rod 502 on the side away from the rotating rod 511. Rectangular holes 504 are opened on the left and right sides of the fixed block 503, and the push rod 502 is arranged on the inner wall of the rectangular hole 504. The push rod 502 passes through the curved rod 602.

[0036] The working principle of this embodiment is as follows: when the heat dissipation net 4 needs to be installed, the side of the heat dissipation net 4 with the square hole 9 is first aligned with the fixed block 503 and pressed down. At this time, the pressing plate 505 moves downward due to the squeezing force of the heat dissipation net 4, driving the first downward pressing rod 506 and the second downward pressing rod 508 to rotate downward, causing the moving rod 509 to move upward, thereby pulling the rotating rod 511 to rotate toward the side away from the fixed block 503. The rotation of the rotating rod 511 pulls the pull rod 507 toward the side close to the fixed block 503, so that the push rod 502 moves from the rectangular hole 504 to the square hole 9, thereby fixing the heat dissipation net 4 and completing the installation.

[0037] Example 2, based on Example 1: Please refer to Figure 3-7 : Elastic mechanism 6, the elastic mechanism 6 includes a protective shell 601, the side of the protective shell 601 close to the cabinet door 2 is fixedly connected to the control cabinet 1, a sliding rod 604 is arranged at the middle end of the inner wall of the protective shell 601, the left and right ends of the sliding rod 604 are fixedly connected to the inner wall of the protective shell 601, the outer wall of the sliding rod 604 is slidably connected with a curved rod 602, a side of the inner wall of the protective shell 601 close to the control cabinet 1 is fixedly connected with a placing plate 606, the top of the placing plate 606 is also fixedly connected with a suspension rod 605, a pull rod 603 is arranged on the top of the placing plate 606, a spring rod 610 is fixedly connected to the top of the pulling rod 603, the top of the spring rod 610 is fixedly connected to the suspension rod 605, the curved rod 602 is slidably connected to the outer wall of the sliding rod 604, The side of the curved rod 602 close to the fixed block 503 is fixedly connected with a second connecting plate 609, the side of the second connecting plate 609 close to the fixed block 503 is fixedly connected with an elastic plate 608, and the side of the elastic plate 608 close to the fixed block 503 is fixedly connected with a first connecting plate 607. By setting the elastic plate 608, when the elastic plate 608 is moved upward, the elastic plate 608 can continue to accumulate force through continuous bending, and when the elastic plate 608 is moving downward, it can rebound, thereby pushing the curved rod 602 to reset through the rebound force, so that it can work next time, and the top of the elastic plate 608 contacts the pulling rod 603.

[0038] The working principle of this embodiment is as follows: when the push rod 503 moves toward the fixed block 503, it will drive the curved rod 602 to move synchronously in the same direction, so that the curved rod 602 pushes the second connecting plate 609 to move in the direction of the first connecting plate 607 during the movement, so that the second connecting rod 609 pushes the elastic plate 608 to start bending upward continuously during the movement, thereby pushing the pulling rod 603 to move upward, so that the spring rod 610 is driven to start compressing during the upward movement of the pulling rod 603 until the pushing rod 503 completes the fixation of the heat dissipation net 4. When the pulling rod 603 moves downward under the pull of the reset mechanism 7, the spring rod 610 loses its support and starts to rebound downward, thereby pushing the elastic plate 608 to move. At this time, the elastic plate 608 is subjected to the downward pressure and starts to stretch downward, resulting in the rebound force of the elastic plate 608 and the spring rod 610. The thrust causes the second connecting plate 609 to move to the side away from the first connecting plate 607, driving the curved rod 602 to move synchronously until it is reset. The movement of the curved rod 602 drives the pushing rod 502 to move to the side away from the fixed block 503. When the pushing rod 502 is moved under the push of the curved rod 602, the pushing rod 502 is moved out of the square hole 9 and moved into the rectangular hole 504. At this time, the staff can remove the heat dissipation net 4. When the pushing rod 502 is moved out, it drives the pull rod 507 to move to the side away from the fixed block 503, so that the pull rod 507 pushes the rotating rod 511 to rotate in the direction of the fixed block 503, so that the rotating rod 511 drives the moving rod 509 to move downward, and the downward rotation of the first pressing rod 506 and the second pressing rod 508 resets the pressing plate 505 to complete the work.

[0039] Example 3, based on Example 2: Please refer to Figure 3-7: Reset mechanism 7, the reset mechanism 7 includes a protective shell 701, the side of the protective shell 701 close to the control cabinet 1 is fixedly connected to the protective shell 601, the bottom of the inner wall of the protective shell 701 is fixedly connected to a bottom plate 703, the top of the bottom plate 703 is fixedly connected to a connecting rod 704, the top of the bottom plate 703 is provided with a load-bearing plate 706 and a top plate 707, the connecting rod 704 penetrates the load-bearing plate 706, and is fixedly connected to the top plate 707, the left and right sides of the bottom plate 703 are rotatably connected to two groups of bending rods 705 through a rotating shaft, and the four groups of bending rods 705 are away from the bottom plate 7 The first contact plate 708 is fixedly connected to the first contact plate 708 on one side of the first contact plate 708, and the first contact plate 708 is fixedly connected to the first contact plate 708 on the side of the first contact plate 708. The first contact plate 708 is fixedly connected to the first contact plate 708 on the side of the first contact plate 708. The first contact plate 708 is fixedly connected to the first contact plate 708 on the side of the first contact plate 708. The rectangular plate 714 is rotatably connected to a rotating block 715 on one side away from the positioning block 711 through a bearing, and the rotating block 715 is fixedly connected to a rotating rod 713 on both sides, and the positioning block 711 is rotatably connected to two sets of support plates 712 on both sides through a rotating shaft, and the four sets of support plates 712 all penetrate the positioning block 711. By setting up four sets of support plates 712, the top rod 716 can be supported to avoid the rebound phenomenon of the spring 710 when the second contact plate 709 moves up again. By setting up the support plates 712, When the second contact plate 709 compresses the spring 710 again, it can be fixed by the push rod 716, so that there is a certain buffer when the spring 710 is compressed again so that the spring 710 will not rebound. The two groups of support plates 712 on the left are fixedly connected to the left rotating rod 713, and the right side is the same. The top of the first contact plate 708 is fixedly connected to the top plate 707, and the top of the second contact plate 709 is fixedly connected with the push rod 716. There are two groups of rebound mechanism 6 and reset mechanism 7, and they are symmetrically arranged with the middle of the fixed block 503 as the center.

[0040] The working principle of this embodiment is as follows: when the pulling rod 603 moves upward, it will drive the hook plate 702 to move upward. When the hook plate 702 moves upward, it will drive the load-bearing plate 706 to move upward on the connecting rod 704. At this time, the bending rod 705 begins to stretch through the continuous upward movement of the load-bearing plate 706, so that the angle of the bending rod 705 continues to increase. When the load-bearing plate 706 moves upward again, it drives the second contact plate 709 to move upward, so that the spring 7109 begins to compress upward. At this time, the push rod 716 also moves synchronously with the upward movement of the second contact plate 709, so that the push rod 716 will enter the interior of the positioning block as it moves continuously. When the push rod 716 contacts the support plate 712 located on the lower side, the support block 712 begins to rotate upward under the upward thrust, so that the push rod 716 can continue to move upward until it moves to the positioning When the heat sink 4 needs to be disassembled, the staff rotates the rotating block 715 counterclockwise, and the rotating block 715 drives the two sets of rotating rods 713 to move, thereby causing the rotating rod 713 to start to move toward one side of the rotating block 715, driving the support block 712 located above to rotate downward, and the support block 712 located below to rotate upward, causing the top rod 716 to lose its supporting force. At this time, the spring 710 loses its upward thrust and begins to rebound, causing the second contact plate 709 to move downward, thereby pushing the load-bearing plate 706 to move downward, causing the hook plate 702 to move downward synchronously. At this time, the bending rod 705 loses its upper pulling force and begins to shrink, causing the load-bearing plate 706 to move downward rapidly, causing the hook plate 702 to pull the pulling rod 603 to move downward until the reset is completed.
