Description

Technical Field

[0001] This utility model relates to the field of DCS system technology, specifically to a display device for DCS systems. Background Technology

[0002] DCS is a technology that integrates computers, communications, displays, and controls for process control and monitoring. DCS displays play a key role in distributed control systems, being assigned to various operator seats. Each display is assigned a display area, known as a viewport, which means that the content is projected onto this specific viewport, thus providing the operator with the necessary view of information.

[0003] The application number "202321436952.9" discloses a "monitoring display supporting a DCS system," which "includes a display screen, a ventilator fixedly connected to the surface of the display screen, a rotating rod fixedly connected to the bottom of the display screen, a base rotatably connected to the end of the rotating rod away from the display screen, a rotating structure provided on the upper surface of the base, the rotating structure including a connecting plate, the connecting plate being fixedly connected to the base, a plurality of connecting rods fixedly connected to the upper surface of the connecting plate, the plurality of connecting rods being threadedly connected to the connecting plate, a circular column fixedly connected to the upper surface of the connecting plate, a rotating shaft fixedly connected to the arc surface of the rotating rod, and a circular groove opened on the rotating shaft corresponding to the position of the circular column, which solves the problem of wear and damage to the display screen during rotation."

[0004] However, the above method still has the following drawbacks: the display screen can be rotated by the rotating shaft, avoiding wear and damage to the base, but the position of the plug and the limiting hole must be matched to limit it. It is difficult to steplessly adjust its rotation angle. Moreover, the position of the rotating structure does not change during the rotation process, and eccentricity is easy to occur during the adjustment process, which will reduce the stability of the display screen and cause it to tip over.

The guide rail 4 can guide the roller 503, and the roller 503 can support the support column 3 to maintain the stability of the support column 3. When the support column 3 rotates, the roller 503 can rotate, which can reduce its rotational resistance.

[0027] In this embodiment, preferably, the adjustment component 6 includes a support 601, a damping shaft 602, and a support plate 603. The bottom end of the support 601 is fixedly connected to the top end of the support column 3. The support plate 603 is hinged to the support 601 through the damping shaft 602. One side of the support plate 603 is fixedly connected to the bottom of one side of the display screen body 1. The top of the support 601 is provided with a mounting groove 604. The support plate 603 is located inside the mounting groove 604. The support plate 603 can be connected to the support 601 through the damping shaft 602, avoiding a rigid connection between the display screen body 1 and the support column 3. The damping shaft 602 can adjust the vertical angle of the display screen body 1 and maintain the stability of the display screen body 1 by relying on its own damping force.

[0028] In this embodiment, preferably, the bottom end of the protective shell 7 is fixedly provided with an installation ring 16, and the bottom end of the installation ring 16 is fixedly connected to the top end of the base 2 by a screw 17. The protective shell 7 can be installed by the installation ring 16 and the screw 17. The bottom end of the installation ring 16 is engaged with a sealing gasket 18, which is located between the installation ring 16 and the base 2. The bottom end of the base 2 is fixedly provided with an anti-slip pad 19. The top of the protective shell 7 is provided with a lubricating oil filling port, and a sealing plug 14 is engaged with one side of the lubricating oil filling port. Lubricating oil can be added into the protective shell 7 through the lubricating oil filling port, and the sealing plug 14 can seal the lubricating oil filling port. The sealing gasket 18 can seal the connection between the installation ring 16 and the base 2, thus preventing the lubricating oil from leaking.

[0029] In this embodiment, preferably, a bearing 20 is provided at both the bottom and top of the vertical shaft 8. A retaining ring 15 is engaged with the surface of one of the bearings 20.

The bearing 21 can support the worm gear 11.

[0030] When in use, the operator places the base 2 on the workbench. The anti-slip pad 19 ensures the anti-slip capability of the base 2. The base 2 supports the display screen body 1 through the support column 3. The operator connects the display screen body 1 to the DCS system. The display screen body 1 can provide the operator with the required information view. When it is necessary to adjust the horizontal direction of the display screen body 1, the operator rotates the worm gear 11 through the knob 13. The worm gear 11 drives the vertical shaft 8 to rotate through the worm wheel 10. The support column 3 can drive the display screen body 1 to make a circular motion along the vertical shaft 8, so that its horizontal angle can be infinitely adjusted, which can maintain the stability of the center of gravity and prevent it from tipping over.

[0031] During adjustment, the guide rail 4 guides the roller 503, which in turn supports the pillar 3, maintaining its stability. When the pillar 3 rotates, the roller 503 rotates, reducing its rotational resistance. After adjustment, the worm gear 11 achieves self-locking of the vertical shaft 8 through angular friction with the worm wheel 10. When the vertical angle of the display screen body 1 needs to be adjusted, the operator can adjust its vertical angle by vertically rotating the display screen body 1 through the damping shaft 602 of the adjustment component 6. The damping shaft 602 maintains the stability of the display screen body 1 by its own damping force.
