It is widely used in fields such as power, petrochemicals, and metallurgy. Current DCS systems utilize traditional industrial standard cabinets, which are generally large. The back panel is connected to the cabinet body via brackets or direct bolts. Patent publication number CN213403845U discloses a DCS cabinet designed for easy installation and maintenance. The cabinet comprises a counterweight base, a cabinet body, a rear panel lift structure, ear panels, a device mounting rear panel, a sealable heat sink structure, rubber pads, through-holes, mounting bolts, a cabinet door, a transparent window, and a door nose. The cabinet body is bolted to the top of the counterweight base; the rear panel lift structure is mounted on the front and rear ends of the cabinet body; the ear panels are welded to the front and rear ends of the lower left side of the cabinet body; and the device mounting rear panel is positioned on the left side of the cabinet body, with its lower portion pivotally connected to the inner side of the ear panels. The beneficial effects of the utility model are as follows: through the arrangement of the winding drum, the driving motor, the wire rope, the connecting plate and the ear plate, it is helpful to control the opening or closing of the upper part of the device installation rear plate, making it convenient for the staff to install the device on the device installation rear plate, and at the same time making it convenient for the staff to detect the device on the device installation rear plate.

In addition, the transmission gear 2 302 and the transmission gear 1 205 are used to achieve the same rotation angle change, so as to ensure that the plate 2 and the mounting frame 301 can reach the horizontal and vertical states synchronously after installation.

[0037] like Figure 2 and Figure 3 In the embodiment, support columns 202 are fixedly installed on the left and right sides of the installation rear plate 2, and a support ring frame 203 is slidably installed on the outside of the support column 202. The sides of the support ring frame 203 are fixedly installed on the outer wall of the cabinet 1. A connecting frame 102 is fixedly installed on the outer wall of the cabinet 1.

The outer wall of the rack 308 and the half gear 406 are meshed with each other, and are rotated and positioned between the card slot 303 and the card shaft 305. The connecting shaft 306 is used to connect all the card shafts 305 to synchronously control all the strip plates 304, thereby achieving control of the sealing and isolation of the installation frame 301. The connecting tube 307 and the connecting shaft 306 are connected by a rotating connection that can be raised and lowered to ensure that the connecting shaft 306 can adapt to the height adaptive changes when the position of the strip plates 304 changes, thereby preventing mutual repulsion of movement.

[0039] like Figure 7 In the embodiment, the locking structure 5 includes a second mounting shaft 501, a hexagonal rod 502 is movably sleeved inside the second mounting shaft 501, a hexagonal column 503 for sleeved inside the hexagonal sleeve 403 is fixedly installed on the top of the hexagonal rod 502, a swivel 504 is rotatably installed on the surface of the bottom end of the hexagonal rod 502, a buckle rod 505 is fixedly installed on the outer wall of the swivel 504, a buckle groove 507 for rotating the buckle rod 505 is opened on the side of the second mounting shaft 501, a spring 1 506 is fixedly connected to the bottom end of the swivel 504, A worm gear 508 is fixedly mounted at the bottom end of the second mounting shaft 501. Several mounting rings 103 for mounting the power mechanism 4 and the second mounting shaft 501 are fixedly mounted on the outer wall of the cabinet 1. Two snap-fit grooves 507 are provided. The first spring 506 is always in a compressed state. The spring 1 506 is always in a compressed state to apply an outward pressure to the rotating ring 504, thereby ensuring that the snap-fit rod 505 is fixed in a stationary state. Similarly, the two positions of the spring 1 506 are used to change the position of the hexagonal column 503, thereby achieving control over the hexagonal sleeve 403.

[0040] like Figure 5 In the embodiment, the power mechanism 4 includes a motor 401, the output shaft of the motor 401 is fixedly sleeved with a worm 402 that meshes with the worm gear 508, and the motor 401 is fixedly installed inside the cabinet 1.

[0042] When the rear panel 2 is to be opened, the motor 401 is started to drive the worm 402 to rotate, and the worm 402 drives the worm gear 508 to rotate, so that the worm gear 508 drives the hexagonal sleeve 403 to rotate through the hexagonal column 503, and the bevel gear 2 405 rotates synchronously at this time, and cooperates with the bevel gear 1 206 and the installation shaft 1 204 to drive the installation rear panel 2 to flip as a whole, the support column 202 slides inside the support ring frame 203, the magnetic strip 201 leaves the inside of the magnetic groove 101, and the installation rear panel 2 gradually tends to be horizontal. While the bevel gear 1 206 rotates, the transmission gear 1 205 also drives the transmission gear 2 302 to rotate, so that the installation frame 301 as a whole also begins to flip, and rotates along the center of the transmission gear 2 302 until the installation frame 301 tends to be horizontal. Then the staff can install the components inside the installation rear panel 2, or press the U-shaped clamping plate 601 to compress the spring 2 603, so that it retracts into the interior of the cabinet 1, and then The heat filter 105 can be taken out from the inside of the cabinet 1. When all the installation work is completed, the rear panel 2 and the heat dissipation sealing assembly 3 can be reset as a whole. When the mounting frame 301 is reset, the rack 308 enters the edge of the inner part of the translation slot 104. At this time, the buckle rod 505 at the upper position can be pulled toward the direction of the worm gear 508 to drive the hexagonal column 503 to disengage from the inside of the hexagonal sleeve 403. The buckle rod 505 moves to the inside of the buckle slot 507 at the bottom to complete the fixation. Then, the motor 401 is started to drive the worm 402 to rotate, and the worm gear 508 drives the bottom half gear 406 to rotate, and the rack 308 drives the connecting pipe 307 to change its lateral position. The connecting pipe 307 drives the connecting shaft 306 to translate, the strip plate 304 rotates, and the connecting shaft 306 adaptively rises and falls until the card shaft 305 is snapped into the inside of the card slot 303 to complete the overall sealing. The overall operation is simple, and all adjustment actions are powered by a single motor 401.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any person skilled in the art may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields.
