Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrical cabinet auxiliary equipment especially relates to a universal support for man-machine interaction equipment in electrical cabinet. BACKGROUND

[0002] With the continuous development of industrial automation technology, as the core installation carrier of power system and industrial control equipment, the internal integrated man-machine interaction equipment (such as touch screen, operation panel, display terminal, etc.) of electrical cabinet has become the key component for staff to monitor equipment running state and input control instruction. Such man-machine interaction equipment needs to adapt to the internal space layout of different specifications of electrical cabinet, and staff often need to read equipment data or perform operation from multiple angles and multiple positions during operation, so high requirements are put forward for the flexibility, stability and adaptability of supporting structure.

[0003] For example, a universal support is proposed in Chinese patent with patent publication number CN203703537U. The length adjustment is realized by the screw hole cooperation of the alpha support rod and the beta support rod and the adjusting bolt, the multi-angle rotation is realized by the movable connection of the alpha ball cavity and the alpha connecting body and the beta ball cavity and the beta connecting body, the support is fixed on the edge of the table, the edge of the bed and other positions by the bench clamp type fixing mechanism, and the tablet computer and other equipment are clamped by the clamping mechanism, so that the problems of easy shaking of the tablet computer during long time holding and easy reflection of the desktop are solved. However, the above-mentioned patent only meets the lightweight use demand of small-sized electronic products for civilian use, and does not consider the industrial scene adaptability of man-machine interaction equipment in electrical cabinet: firstly, the bench clamp type fixing mechanism of the patent can only be fixed on the edge of the plane, and cannot adapt to the complex three-dimensional space (such as irregular installation surface of cabinet beam, stand column, etc.) in the electrical cabinet, and the fixing strength is insufficient, which is difficult to bear the weight of industrial grade man-machine interaction equipment; secondly, the clamping mechanism drives the clamping plate to move through the screw rod and the adjusting knob, the clamping force adjustment precision is low, and only the thin size of the tablet computer can be adapted, and different thicknesses and different installation hole positions of industrial grade man-machine interaction equipment cannot be compatible; thirdly, the patent lacks vibration buffering design, the alpha and beta balls and the ball cavity are only fixed by friction force, which is easy to deviate in the electrical cabinet vibration environment, and the stability of equipment operation cannot be guaranteed; fourthly, the support rod of the patent is a two-section structure, the adjustment range is limited, and it is difficult to meet the space layout demand of different depths and heights in the electrical cabinet.

[0038] Reference Figures 1-6 A universal bracket for a human-machine interface device in an electrical cabinet includes a mounting base 1, which is fixedly installed on the inner wall of the electrical cabinet, and further includes:

[0039] The mounting base 1 has a groove on its surface, and slots are provided on both sides of the groove. A sliding structure 6 is slidably mounted on the mounting base 1.

[0040] The first connecting rod 2 is fixedly installed on one side of the sliding structure 6, and the other end of the first connecting rod 2 is hingedly installed with the second connecting rod 3, and the other end of the second connecting rod 3 is fixedly installed with the mounting sleeve 7, and one side of the mounting sleeve 7 is fixedly installed with the locking box 8, and the inside of the locking box 8 is provided with a locking structure.

[0041] The top end of the mounting sleeve 7 is sleeved with the supporting rod 4, and the other end of the supporting rod 4 is installed with the connecting structure 5, and the other end of the connecting structure 5 away from the supporting rod 4 is hingedly installed with the human-computer interaction fixing seat for installing the human-computer interaction device.

[0042] Further, the supporting rod 4 includes a fixed rod 9, a spring damper 10 and a connecting plate 11, the inside of the mounting sleeve 7 is sleeved with a rotating seat, and the two ends of one side of the rotating seat are respectively hingedly installed with the fixed rod 9;

[0043] The two sides of the two groups of fixed rods 9 are respectively provided with a group of spring dampers 10, and the two ends of the two groups of spring dampers 10 are respectively hingedly installed with the two groups of fixed rods 9;

[0044] The other end of the two groups of fixed rods 9 is hingedly installed with a group of connecting plates 11, and the other end of the connecting plate 11 is hingedly installed with the connecting structure 5, and the hinged cooperation of the two groups of fixed rods 9 and the rotating seat provides the device with basic rotating adjustment capability; and the design that the two ends of the two groups of spring dampers 10 are respectively hingedly installed with the fixed rod 9 not only plays a buffering role in the device adjustment process, avoids damage to the device due to excessive force during adjustment, but also stably maintains the current position of the device after adjustment, preventing the device from deviating due to vibration or external force touch. At the same time, the hinged cooperation of the connecting plate 11 and the connecting structure 5 further expands the adjustment range of the device, ensuring that the staff can clearly observe and conveniently operate the human-computer interaction device at different positions and different operating angles of the electrical cabinet, greatly improving the use flexibility and operation comfort of the device.

[0045] Further, the locking structure includes a gripping plate 12, a sliding plate 13 and a threaded screw rod 14, and the threaded screw rod 14 is rotatably installed on the side of the locking box 8 away from the mounting sleeve 7;

[0047] The two groups of sliding plates 13 are fixedly installed with a rack on the side close to the inside of the locking box 8, and the threaded screw rod 14 can drive the subsequent components to link when rotating, and through the sliding of the two groups of sliding plates 13 in the sliding groove of the locking box 8, the clamping plate 12 is driven to move to the inside of the mounting sleeve 7, and the clamping and fixing of the supporting rod 4 are realized. Compared with the traditional buckle or bolt fixing, this threaded transmission type locking method has the advantages of high adjustment accuracy and controllable locking force, and can accurately control the clamping degree of the clamping plate 12 according to the diameter of the supporting rod 4 or the installation requirement, so as to avoid the shaking of the supporting rod 4 due to loose fixing or the damage of the supporting rod 4 due to tight fixing.

In addition, this extension design avoids the situation that the clamping plate 12 is clamped only at the edge of the mounting sleeve 7, reduces the problem of excessive local stress of the supporting rod 4, protects the structural integrity of the supporting rod 4, and at the same time ensures the stability and long-term effectiveness of the locking structure for fixing the supporting rod 4, which provides important support for the stable installation of the human-computer interaction equipment.

[0052] The two sides of the moving plate 15 away from the threaded screw rod 14 are respectively hingedly installed with two groups of hinged rods 16, when the threaded screw rod 14 rotates to drive the moving plate 15 to slide, the moving plate 15 drives the two groups of half gears 17 to rotate synchronously through the two sides of the hinged rods 16, and the half gears 17 are in meshing cooperation with the rack of the sliding plate 13, which can ensure that the two groups of sliding plates 13 always maintain a symmetrical and synchronous sliding state, and then the two groups of clamping plates 12 realize uniform clamping of the support rod 4. The synchronous transmission design avoids the clamping deviation and unstable fixation caused by the asynchronous movement of the two groups of clamping components in the traditional locking structure, and the threaded cooperation between the threaded screw rod 14 and the moving plate 15 has a self-locking function, which can stably maintain the position of the moving plate 15 after locking, prevent the locking structure from loosening due to external force, and significantly improve the stability and operation convenience of the locking structure.

The structure design greatly reduces the operation difficulty of the position adjustment of the equipment, improves the adjustment efficiency, ensures the stability of the equipment after being fixed, and meets the equipment position demand in different operation scenes in the electrical cabinet.
