Description

Technical Field

[0001] This invention belongs to the field of human resource performance display technology, specifically a human resource intelligent performance display stand device. Background Technology

[0002] Human resource management refers to a series of activities guided by economics and humanistic principles, which effectively utilize relevant human resources inside and outside an organization through management methods such as recruitment, selection, training, and compensation to meet the organization's current and future development needs and ensure the maximization of organizational goals and member development. In human resource management departments, it is often necessary to compare the performance of employees in different departments to determine the best-performing group or individual for the month. Human resource management requires dedicated performance display devices.

[0003] A patent with announcement number CN217178026U discloses an intelligent display device for human resource performance, including a base. Four casters are installed at the four corners of the base's bottom, and brake pads are installed on one side of each caster. An electric push rod is fixedly connected to the center of the top of the base. A mounting platform is fixedly connected to the top of the electric push rod, and adjusting rods are fixedly connected to both sides of the bottom of the mounting platform. A support spring is installed inside the adjusting rod, and a slider is installed on the outer wall of the adjusting rod. A fixed rod is installed at the bottom of the outer side of the adjusting rod. This invention utilizes the electric push rod. When the height of the smart screen needs to be adjusted, the electric push rod is activated, extending and causing the smart screen to move upwards. Simultaneously, the adjusting rod slides inside the fixed rod, causing the slider and the groove to slide internally, and stretching the support spring. The support spring increases the stability of the connection between the adjusting rod and the fixed rod, thus keeping the smart screen stable during use.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 9 As shown, an embodiment of the present invention provides a human resources intelligent performance display stand device, including a mobile shelf 11 and a limiting sleeve 12 fixedly installed on the bottom two sides of the mobile shelf 11. A protective sleeve 112 is fixedly installed on the inner wall of the mobile shelf 11, and a display projection cloth 113 is provided on the inner wall of the protective sleeve 112. Two limiting strips a7 are fixedly connected to the top outer surface of the mobile shelf 11, and a sliding rod a8 is provided in the middle of the two limiting strips a7. A slider a9 is movably sleeved on the outer surface of the movable shelf 11. A rotating sleeve a12 is oscillatingly sleeved on the inner wall of the slider a9. A motor a13 is fixedly installed on the inner wall of the rotating sleeve a12. A threaded rod a14 is fixedly connected to the output end of the motor a13. A mating block 116 is provided on the outer surface of the threaded rod a14. A threaded arc-shaped block 119 is provided on the inner wall of the mating block 116, which is movably sleeved on the outer surface of the threaded rod a14. A projector a5 is provided on the front of the movable shelf 11.

[0023] When the mobile shelf 11 is transported to the appropriate position, the rotating sleeve a12 is rotated so that the threaded rod a14 is in a vertical state. At this time, the slider a9 slides on the surface of the limiting strip a7 and the sliding rod a8, so that the sliders a9 on both sides of the mobile shelf 11 can be aligned. After the threaded rod a14 is aligned, the surface of the threaded rod a14 is fitted into the interior of the docking block 116, and the threaded rod a14 is rotated by the motor a13, so that the threaded rod a14 rotates on the inner wall of the threaded arc block 119, and the docking block 116 drives the display projection cloth 113 to move upward. The unfolded display projection cloth 113, together with the projector a5, projects the image onto the surface of the display projection cloth 113 for display. During disassembly, motor a13 is used to rotate and move the docking block 116 downward, and the display projection cloth 113 is rolled up by the protective sleeve 112. Rotating the rotating sleeve a12 retracts the threaded rod a14 into the interior of the movable shelf 11, and the two threaded rods a14 are stacked together. By utilizing the length of the threaded rod a14 and the expansion area and range of the display projection cloth 113, the display area and range are increased.

[0024] like Figures 1 to 5 , Figure 7 and Figure 9As shown, an inlet / outlet notch is provided on the outer surface of one end of the connecting block 116. Extrusion flexible plates 117 are provided on the inner walls of both sides of the connecting block 116. A recessed groove 118 is provided on the inner wall of the connecting block 116. The outer surface of the threaded arc-shaped block 119 is fixedly installed on the inner wall of the recessed groove 118. Two sets of sealing covers 111 are oscillatingly connected to the top surface of the movable shelf 11. A slot a6 is provided on the top surface of the movable shelf 11. An elastic pusher is fixedly connected to the bottom surface of the sealing cover 111. The moving wire 1110 has an arc-shaped pad 1111 fixedly connected to one end of the elastic pushing wire 1110. The bottom surface of the arc-shaped pad 1111 is provided with anti-slip texture 1112. The display projection cloth 113 has a closed overlap cover 114 fixedly connected to one end. The inner wall of the closed overlap cover 114 is movably overlapped on the top surface of the protective sleeve 112. The outer surface of the closed overlap cover 114 is fixedly connected with a limit rod 115. The outer surfaces of the two sets of docking blocks 116 are fixedly installed on both ends of the limit rod 115.

[0025] When the closed overlap cover 114 swings and engages with the docking block 116, the pressure plate 117 guides the position of the closed overlap cover 114, allowing it to engage with the docking block 116. The threaded arc block 119 inside the docking block 116 limits the position of the closed overlap cover 114, and when the closed overlap cover 114 rotates inside the threaded arc block 119, the docking block 116 can move upward under the action of the threaded arc block 119. When the closed overlap cover 114 moves the docking block 116 upward, the docking block 116 moves the limiting rod 115 upward and downward. At the same time, the closed overlap cover 114 on the bottom surface of the limiting rod 115 seals and presses against the top surface of the protective sleeve 112, and seals the entrance of the protective sleeve 112 through the closed overlap cover 114, reducing the excessive contact between the display projection cloth 113 inside the protective sleeve 112 and the outside world.

[0026] like Figures 4 to 6As shown, the outer surface of the threaded rod a14 is movably sleeved on the inner wall of the threaded arc block 119. An arc groove a10 is provided on the bottom inner wall of the slider a9. An arc limiting plate a11 is movably sleeved on the inner wall of the arc groove a10, and the outer surface of the arc limiting plate a11 is movably overlapped on the outer surface of the rotating sleeve a12. Rectangular grooves are provided on the bottom surfaces of both sides of the slider a9. The inner wall of the rectangular groove is slidably sleeved on the outer surface of the limiting strip a7. A snap-fit ​​latch a1 is provided on one edge of the top of the movable shelf 11. An overlapping support plate a2 is movably sleeved on the outer surface of the snap-fit ​​latch a1. A mating latch a3 is fixedly connected to the bottom surface of the overlapping support plate a2, which is movably overlapped on the outer surface of the movable shelf 11. A limiting cover plate a4 is provided on one top surface of the overlapping support plate a2. The projector a5 is located on the inner wall of the limiting cover plate a4.

[0027] When the rotating sleeve a12 swings to a vertical position, the arc-shaped limiting plate a11 is engaged with the inner wall of the arc-shaped groove a10, so that the inner wall of the arc-shaped limiting plate a11 can fit against the outer surface of the rotating sleeve a12. At this time, the verticality of the arc-shaped limiting plate a11 is used to keep the rotating sleeve a12 in a vertical state, so as to avoid the threaded rod a14 from swinging under the pulling of the projection cloth 113 during later use. After the mobile shelf 11 is placed, the docking latch a3 on one end of the overlapping support plate a2 is overlapped with the top surface of the mobile shelf 11 and the snap-fit ​​latch a1. At this time, the position of the overlapping support plate a2 is limited by the docking latch a3, so that the overlapping support plate a2 is in a horizontal state, and the projector a5 on the top surface of the overlapping support plate a2 projects the image onto the outer surface of the display projection cloth 113, and displays the performance.

[0028] like Figure 1 and Figure 8 As shown, a swing arm 121 is oscillatingly connected to the inner wall of the limiting sleeve 12. A mating groove 122 is formed on the bottom surface of one end of the swing arm 121. An elastic buffer wire 123 is fixedly connected to the inner wall of the mating groove 122. A snap-fit ​​sleeve 124 is fixedly connected to one end of the elastic buffer wire 123. A supporting hollow column 125 is oscillatingly connected to the bottom surface of one end of the swing arm 121. The outer surface of one end of the supporting hollow column 125 is movably overlapped on the inner wall of the snap-fit ​​sleeve 124.

[0029] When the mobile shelf 11 is moved to the appropriate position, the swing arm 121 is unfolded from the inside of the limiting sleeve 12, and the supporting hollow column 125 is peeled off from the inside of the snap-fit ​​sleeve 124. The supporting hollow column 125 is used to support the bottom surface of one end of the swing arm 121.

[0030] Working principle: When the mobile shelf 11 moves to the appropriate position, the swing arm 121 is unfolded from the inside of the limiting sleeve 12, and the supporting hollow column 125 is peeled off from the inside of the snap-fit ​​sleeve 124. The supporting hollow column 125 is used to support the bottom surface of one end of the swing arm 121. When the mobile shelf 11 is transported to the appropriate position, the rotating sleeve a12 is rotated so that the threaded rod a14 is in a vertical state. At this time, the slider a9 slides on the surface of the limiting strip a7 and the sliding rod a8, so that the sliders a9 on both sides of the mobile shelf 11 can be aligned. After the threaded rod a14 is aligned, the surface of the threaded rod a14 is fitted into the interior of the docking block 116, and the threaded rod a14 is rotated by the motor a13, so that the threaded rod a14 rotates on the inner wall of the threaded arc block 119, and the docking block 116 drives the display projection cloth 113 to move upward. The unfolded display projection cloth 113, together with the projector a5, projects the image onto the surface of the display projection cloth 113 for display. During disassembly, motor a13 is used to rotate and move the docking block 116 downward, and the display projection cloth 113 is rolled up by the protective sleeve 112. Rotating the rotating sleeve a12 retracts the threaded rod a14 into the interior of the movable shelf 11, and the two threaded rods a14 are stacked together. By utilizing the length of the threaded rod a14 and the expansion area and expansion range of the display projection cloth 113, the display area and range are increased. When the rotating sleeve a12 swings to a vertical position, the arc-shaped limiting plate a11 is engaged with the inner wall of the arc-shaped groove a10, so that the inner wall of the arc-shaped limiting plate a11 can fit against the outer surface of the rotating sleeve a12. At this time, the verticality of the arc-shaped limiting plate a11 is used to keep the rotating sleeve a12 in a vertical state, so as to avoid the threaded rod a14 from swinging under the pulling of the projection cloth 113 during later use. After the mobile shelf 11 is placed, the docking latch a3 on one end of the overlapping support plate a2 is overlapped with the top surface of the mobile shelf 11 and the snap-lock a1. At this time, the position of the overlapping support plate a2 is limited by the docking latch a3, so that the overlapping support plate a2 is in a horizontal state, and the projector a5 on the top surface of the overlapping support plate a2 projects the image onto the outer surface of the display projection cloth 113, and displays the performance. When closing the hollow support column 125 later, one end of the hollow support column 125 is extended and overlapped into the inner wall of the snap-fit ​​sleeve 124. At this time, the snap-fit ​​sleeve 124 is elastically pushed by the elastic buffer wire 123, so that the snap-fit ​​sleeve 124 can be firmly attached to the surface of one end of the hollow support column 125, and the position of the hollow support column 125 is limited.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
