[0032] like Figures 1-6 As shown, the present invention provides an information input auxiliary device, comprising:

[0033] A support cylinder 1 is horizontally arranged. The support cylinder 1 is a hollow cylindrical cylinder. The two ends of the support cylinder 1 extend outward along its axial direction to form annular protrusions 2. The protrusions 2 are provided with arc-shaped openings 3 along their circumference. The two ends of the openings 3 are located on the rear side of the support cylinder 1.

[0034] A rotating shaft 4 is disposed inside the support cylinder 1 and arranged along the axial direction of the support cylinder 1. Both ends of the rotating shaft 4 extend out of the end face of the support cylinder 1 and are rotatably connected to it. The rotating shaft 4 is driven to rotate by a driving component disposed inside the support cylinder 1.

[0035] Multiple pairs of connecting balls 5, any pair of connecting balls 5 are disposed opposite each other at both ends of the support cylinder 1, and any connecting ball 5 is slidably sleeved on the part of the protrusion 2 located outside the opening 3;

[0036] A pair of bushings 6 are respectively fixedly sleeved at both ends of the rotating shaft 4. A drive rod 7 is provided on each bushing 6 along its radial direction. The drive rod 7 is detachably connected to the connecting ball 5 near the front side of the support cylinder 1 through a connector.

[0037] Multiple display panels 8 correspond one-to-one with the multiple pairs of connecting balls 5. Each display panel 8 is located at the end of the corresponding pair of connecting balls 5 away from the bushing 6 and is fixedly connected to the connecting balls 5.

[0038] The support column 9 includes an inclined part 91 and a vertical part 92. The upper end of the inclined part 91 is fixedly connected to the rear outer wall of the support cylinder 1, and the lower end is fixedly connected to the vertical part 92.

[0039] A base plate 10 is horizontally positioned, and its top surface is fixedly connected to the lower end of the vertical portion 92; wherein,

[0040] The support column 9 is configured not to interfere with the drive rod 7 driving the connecting ball 5 to rotate around the opening 3.

[0041] In the above implementation scheme, the information input auxiliary device includes a support cylinder, a rotating shaft, multiple pairs of connecting balls, a pair of bushings, multiple display panels, and a base plate. The support cylinder is a horizontally positioned, hollow cylindrical tube. Both ends of the support cylinder have annular protrusions extending outwards along its axial direction. Each protrusion has a circumferentially curved opening, with both ends located at the rear of the support cylinder. Preferably, both ends of the opening are located at the center of the rear of the support cylinder to facilitate the arrangement of the connecting balls. The rotating shaft is located axially within the support cylinder, with both ends extending through the end faces of the support cylinder and rotatably connected to the end faces of the support cylinder via bearings. The rotating shaft is driven to rotate by a driving component located within the support cylinder. The driving components include, but are not limited to, belt drive assemblies, chain drive assemblies, and gear drive assemblies; the multiple pairs of connecting balls are slidably sleeved on the portion of the protrusion located outside the opening, with each pair of connecting balls positioned opposite each other at both ends of the support cylinder; the pair of bushings are fixedly sleeved on both ends of the rotating shaft, with a drive rod fixedly mounted radially on each bushing, and the end of the drive rod away from the bushing being detachably connected to a connecting ball near the front side of the support cylinder via a connector, so that the drive rod can drive the connecting ball connected to it to rotate around the opening; the multiple display panels are connected to the multiple pairs of connecting balls... Each pair of connecting balls corresponds to a specific ball, with each display panel located at the end of the corresponding pair of connecting balls furthest from the bushing and fixedly connected to it. Preferably, the length of the display panel is arranged along the axial direction of the support cylinder, and the width is arranged along the radial direction of the support cylinder, so that when the display panel is located at the bottom of the support cylinder, it faces the technicians, facilitating their viewing of the construction information on the display panel. The support portion is located on the rear side of the support cylinder and includes an inclined portion and a vertical portion. The upper end of the inclined portion is fixedly connected to the rear outer wall of the support cylinder, and the lower end is fixedly connected to the upper end of the vertical portion. Preferably, the inclined portion... The upper end of the inclined portion is located in the middle of the rear outer wall of the support cylinder. One opposite side of the upper end of the inclined portion is parallel to the axial direction of the support cylinder, and the extension line of the opposite side along the axial direction of the support cylinder does not intersect the opening. More preferably, the length direction of the inclined portion is arranged along the radial direction of the support cylinder to minimize the influence of the support column on the rotation of the display board, so that the support column does not interfere with the drive rod driving the connecting ball to rotate around the opening. The bottom is horizontally located below the support column and is fixedly connected to the support column so that the device can be stably placed on the table.

[0042] In use, the device is placed next to the computer. Technicians manually fix forms containing construction information onto multiple display boards. The technician sits at their workstation and adjusts the angle of the device so that the display board in front is directly in line with their line of sight. The technician enters the construction information from the form. After the current form information is entered, the control drive rod connects to the pair of connecting balls corresponding to the current form. Then, the drive mechanism is activated, causing the drive mechanism to rotate the shaft, which in turn drives the bushing. The bushing drives the drive rod, which in turn drives the connecting balls. The connecting balls cause the display board to rotate around the opening, automatically flipping the display board to the rear of the support cylinder. Then, the drive rod is disconnected from the connecting balls and reset. At the same time, the display board behind the current display board slides downwards under the action of the corresponding connecting balls until it is directly in line with the technician's line of sight. The process of entering form information and flipping display boards is repeated until all construction information is entered.

[0043] This invention fixes a form containing construction information to a display board. During the data entry process, a drive mechanism, rotating shaft, bushing, drive rod, connector, and connecting ball drive the corresponding display board to rotate along the opening, achieving automatic rotation of the display board. This effectively improves the efficiency of data entry. Furthermore, because the form is directly opposite the technician's line of sight during entry, there is no need to look down, effectively avoiding neck and shoulder discomfort. Of course, this device can also be applied to other scenarios requiring paper-based data entry, such as financial data entry and sales data entry.

[0044] In another embodiment, the information input auxiliary device includes a support cylinder 1 comprising: a support shaft 11, which is a hollow cylinder open at both ends, the support shaft 11 being arranged along the axial direction of the support cylinder 1, and a notch at the top of the support shaft 11; two support plates 12, which are circular plates, the two support plates 12 being fixedly disposed at both ends of the support shaft 11 and coaxially disposed therewith, the diameter of the support plates 12 being larger than the diameter of the support shaft 11; a protrusion 2 being disposed on the side of the support plate 12 away from the support shaft 11; a rotating shaft 4 being sleeved inside the support shaft 11, the two ends of the rotating shaft 4 passing through the two support plates 12 respectively and being rotatably connected to the two support plates through bearings; and a protective cover 13 being sleeved outside the support shaft 11, the protective cover 13 being coaxially disposed with the support shaft 11, and the two ends of the protective cover 13 being respectively connected to the support shaft 11. The two support plates 12 are detachably connected on the side near the support shaft 11. The detachable connection methods include, but are not limited to, screw connections and snap-fit ​​connections. The protective cover 13 is provided with heat dissipation holes. The driving component includes: a fixed shaft 14, which is fixedly disposed within the notch and is arranged axially along the support shaft 11; a first driven gear 15, which is rotatably sleeved on the fixed shaft 14; a driving gear 16, which is disposed above and meshes with the first driven gear 15, and the driving gear 16 is driven to rotate by a motor 23 fixedly disposed on the top of the support shaft 11. Preferably, the motor 23 is a stepper motor, which drives the rotating shaft to reciprocate in both forward and reverse directions, with each rotation angle being 180 degrees; and a second driven gear 17, which is fixedly sleeved on the rotating shaft 11 and meshes with the first driven gear 15. Here, by defining the specific structure of the support cylinder and the driving component, the installation of the driving component is facilitated, and stable driving of the rotating shaft is achieved.

[0045] In another embodiment, the information input auxiliary device has a through hole 18 on the connecting ball 5. The connecting ball 5 is slidably sleeved on the portion of the protrusion 2 located outside the opening 3 through the through hole 18, and the radial length of the through hole 18 along the support cylinder 1 is greater than the wall thickness of the protrusion 2, so that the through hole can move radially along the support cylinder. A stop (not shown) is fixedly provided on the portion of the protrusion 2 located outside the opening 3. The stop is located at the bottom of the protrusion 2 near the rotating shaft 4. Preferably, the stop is located at the lower extreme point of the protrusion. The stop is configured such that when the connecting ball 5 near the front side of the support cylinder 1 is not connected to the drive rod 7, the stop cannot pass through the through hole 18, and when the connecting ball 5 near the front side of the support cylinder 1 is connected to the drive rod 7, the stop can pass through the through hole 18. Here, by setting a stop and limiting the relationship between the stop and the perforation, when the drive rod is not connected to the connecting ball near the front side of the support cylinder, the connecting ball, under the action of its own weight and the weight of the display panel, will have the end of the perforation on the connecting ball near the bushing contact the part of the protrusion located outside the opening. The stop cannot pass through the perforation, preventing the connecting ball from continuing to slide along the opening. When the drive rod is connected to the connecting ball near the front side of the support cylinder, the connecting ball moves upward under the action of the connector. The end of the perforation on the connecting ball away from the bushing contacts the part of the protrusion located outside the opening. The stop can pass through the perforation, without restricting the drive rod from driving the connecting ball to continue sliding along the opening, so that the drive rod can drive the display panel to flip through the connecting ball.

[0046] In another embodiment, the information input auxiliary device includes an upper connector and multiple lower connectors arranged radially along the support cylinder 1, with each lower connector corresponding to a connecting ball 5. The upper connector includes a first groove located at the end of the drive rod 7 away from the bushing 6, and an electromagnet 19 fixedly disposed within the first groove. Each lower connector includes a connecting rod 20 fixedly disposed at the end of the connecting ball 5 near the bushing 6, a second groove located at the end of the connecting rod 20 near the bushing 6, and a magnet 21 fixedly disposed within and protruding from the second groove. The magnet 21 is configured such that when the electromagnet 19 is energized, the portion protruding from the second groove extends into the first groove and attracts the electromagnet 19; when the electromagnet 19 is de-energized, the portion protruding from the second groove de-energizes and exits the first groove. Here, a preferred structure for the connector is defined, in which the upper and lower connectors are detachably connected by electromagnets and magnets, which facilitates operation and control.

[0047] In another embodiment, the information input auxiliary device further includes a touch screen controller 22, which is disposed on the base plate 10. The touch screen controller 22 is electrically connected to the motor 23 and the electromagnet 19. The touch screen controller 22 includes a detection component and a control component. The control component is electrically connected to the motor 23 and the electromagnet 19. The control component has built-in control logic, which first controls the electromagnet 19 to be energized, then controls the motor 23 to rotate forward by a preset angle, then controls the electromagnet 19 to be de-energized, and finally controls the motor 23 to rotate backward by a preset angle to reset. The detection component is used to detect touch operations. When a touch operation is detected, a touch signal is transmitted to the control component. The control component controls the motor 23 and the electromagnet 19 to operate according to the control logic. Here, by setting a touch screen controller, the display board can be easily controlled to complete automatic flipping.

[0048] In another embodiment, the information input auxiliary device includes a display panel 8 comprising a base plate 81, which is a square plate, with T-shaped grooves on opposite sides of the base plate 81 along its length; a pair of guide plates 82, fixedly disposed on opposite sides of the base plate 81, with a guide groove 83 on the inner side of each guide plate 82 along its length, the guide groove 83 communicating with the T-shaped groove; a pair of pressure plates 84, spaced apart along the length of the base plate 81, each pressure plate 84 perpendicular to the pair of guide plates 82, with both ends of each pressure plate 84 located within the guide groove 83, and a rubber strip 85 on the side of each pressure plate 84 near the base plate 81; and four connecting posts disposed at both ends of the pressure plates 84 near the base plate 81. On one side of the base plate 81, any connecting post is perpendicular to the pressure plate 84. The connecting post includes a slidingly fitted outer post 86 and an inner post 87. The end of the outer post 86 away from the pressure plate 84 is fixedly connected to a slider 88, which is slidably engaged within the T-shaped groove. The end of the inner post 87 near the pressure plate 84 is fixedly connected to the pressure plate 84, and the other end is connected to the end of the outer post 86 away from the pressure plate 84 via a spring 89. When the spring 89 is in its initial state, the rubber pressure strip 85 can press and fix the form laid flat on the base plate 81. When the spring 89 is in its maximum tension state, the rubber pressure strip 85 cannot press and fix the form laid flat on the base plate, and the pressure plate 84 can slide freely along the T-shaped groove, allowing for free adjustment of the pressure plate 84's position. This defines a preferred structure for the display panel, facilitating the fixing of forms of different sizes laid flat on the base plate using the pressure plate.

[0049] Furthermore, to better adjust the position of the pressure plate 84, two elongated mounting holes are spaced apart along its length. A mounting rod 810 is fixedly mounted in the middle of each mounting hole along its width. A support rod 811 is rotatably connected to the mounting rod 810. Multiple ball bearings 812 are embedded in the end of the support rod 811 away from the adjacent guide plate 82. A multi-stage telescopic rod 813 is provided between the two mounting holes. The multi-stage telescopic rod 813 is perpendicular to the pressure plate 84. One end of the multi-stage telescopic rod 813 is fixedly connected to the side of the pressure plate 84 away from the base plate 81, and the other end, adjacent to the two mounting holes, is connected to the support rod 811 via connecting rods 814. One end of the connecting rod 814 is connected to the multi-stage telescopic rod 813. The rod 813 is hinged at one end, and the other end is hinged to the end of the support rod 811 near the guide plate 82 adjacent to it. The rubber pressure strip 85 has a channel 815 communicating with the mounting hole at the position opposite to the mounting hole. The support rod 811 can rotate around the mounting rod 810 under the drive of the connecting rod 814 and the multi-stage telescopic rod 813. When the multi-stage telescopic rod 813 is in the shortest position, the support rod 811 is located in the mounting hole, and the spring 89 is in the initial state. When the multi-stage telescopic rod 813 is in the longest position, the support rod 811 is perpendicular to the pressure plate 84, and the multiple balls 812 are in contact with the base plate 81. The spring 89 is in the maximum tension state, so as to more conveniently adjust the position of the pressure plate freely.

[0050] In another embodiment, the information input auxiliary device has screws (not shown) fixed at each of the four bottom corners of the base plate 81. The screws (not shown) are perpendicular to the base plate 81, and a height adjusting nut is threaded to the lower end of each screw. The height adjusting nut includes a threaded sleeve and a washer. The threaded sleeve is threaded to the lower end of the screw, and the washer is fixed to the bottom of the threaded sleeve and coaxially arranged therewith, with a diameter larger than the outer diameter of the threaded sleeve. Here, the screws and the height adjusting nut threaded to them facilitate adjustment of the levelness of the base plate.

[0051] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
