Description

Technical Field

[0001] This invention relates to the field of software engineering technology, specifically to an adjustable electronic display board for software engineering. Background Technology

[0002] In the entire process of modern software engineering development, project iteration and application implementation, scenarios such as project reporting, technical defense, team discussion, solution demonstration and results acceptance are extremely frequent. It is necessary to use electronic display boards to display core technical content such as program code, system architecture drawings, functional logic flowcharts, software test data, interface prototype effects and project progress information in real time.

[0003] Because software engineering demonstration scenarios are highly flexible, have a wide audience, are not fixed in location, and have varying demonstration durations, demonstration equipment needs to be adapted to different meeting room spaces and different sitting and standing postures of participants. Therefore, liftable electronic display boards are commonly used as the core demonstration equipment in the market, which can meet the visualization needs of multiple angles and multiple working conditions through height adjustment.

[0004] While traditional electronic display boards for software engineering currently possess basic height adjustment functions, their lifting and telescopic structures, often relying on simple column sliding mechanisms, lack targeted automatic lubrication and stabilizing limit mechanisms during long-term, high-frequency office presentations. This leads to problems such as dryness, jamming, wear, and loosening of the sliding parts after frequent adjustments. This not only results in choppy and inaccurate height adjustment operations but also causes the display board to shake and the image to shift, severely impacting the presentation of software drawings and data charts, and disrupting the overall progress of project reports and technical discussions.

[0005] Therefore, an adjustable electronic display board for software engineering is proposed to address the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable electronic display board for software engineering, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An adjustable electronic display board for software engineering includes a stabilizing plate, a sliding column fixedly connected to the top of the stabilizing plate, a lifting column slidably engaged inside the sliding column, a display board body fixedly connected to the top of the lifting column, and a pushing and lubricating mechanism provided between the sliding column and the lifting column.

[0009] The lifting column has a rotating groove in its side wall, and a ball bearing is installed inside the rotating groove. The lifting column also has a U-shaped guide groove inside, and a through hole is provided between the U-shaped guide groove and the rotating groove.

[0010] The lubrication mechanism includes an electric telescopic rod, a push rod fixedly connected to the top of the electric telescopic rod, a sliding rod fixedly connected to the outer side of the push rod, a moving groove opened in the side wall of the sliding rod, a nylon rod movably engaged in the inner bottom wall of the moving groove, a return spring sleeved on the nylon rod, a pressing disc fixedly connected to the outer side of the sliding rod, a squeezing rod fixedly connected to the top of the tail end of the sliding rod, a lubricant bladder fixedly connected to the outer side of the sliding rod, a telescopic conduit fixedly connected to the top of the lubricant bladder, and an oil guide pipe fixedly connected to the top of the telescopic conduit.

[0011] As a further optimization of the present invention, a positioning mechanism is provided between the sliding column and the lifting column. The positioning mechanism includes a hinge plate, a connecting rod is provided on the outer side of the hinge plate, an L-shaped snap-fit ​​plate is fixedly connected to the outer side of the connecting rod, and a positioning plate is fixedly connected to the outer side of the sliding column.

[0012] As a further optimization of the present invention, the rotating grooves are symmetrically distributed on both sides of the lifting column, the balls are evenly distributed inside the rotating grooves, and the balls roll tightly against the inner wall of the sliding column.

[0013] As a further optimization of the present invention, the U-shaped guide channel is sealed at both ends and is located outside the rotating channel, and the through holes are evenly distributed between the U-shaped guide channel and the rotating channel.

[0014] As a further optimization of the present invention, the electric telescopic rod is fixedly connected to the inner bottom wall of the sliding column, and the top of the push rod is fixedly connected to the bottom of the lifting column.

[0015] As a further optimization of the present invention, the sliding rods are symmetrically distributed on the outside of the push rod, and the tail end of the sliding rod is located on the outside of the sliding column.

[0016] As a further optimization of the present invention, the top of the nylon rod is fixedly connected to the top of the sliding rod, and the sliding rod is slidably connected inside the moving groove.

[0017] As a further optimization of the present invention, the extrusion rod is located below the lubricant bladder, and the end of the oil guide tube away from the telescopic guide tube is fixedly connected to the inside of the U-shaped guide groove.

[0018] As a further optimization of the present invention, the hinge plates are symmetrically distributed on the outside of the lifting column, the positioning plates are evenly and symmetrically distributed on the outside of the sliding column, and the bottom of the L-shaped snap-fit ​​plate is snapped between the two positioning plates.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, the equipped lubrication mechanism enables automated and precise lubrication of the lifting structure. During the height adjustment process of the lifting column driven by the electric telescopic rod, the device simultaneously compresses the lubricant bladder, allowing the lubricant to be introduced through the conduit into the U-shaped guide groove and evenly permeate to the ball contact surface through the through-hole. This structure eliminates the need for frequent manual lubrication, effectively reducing equipment maintenance difficulty and costs. It continuously ensures smooth operation between the lifting column and the sliding column, eliminating problems such as lifting jamming and dryness, significantly improving the smoothness and efficiency of display board height adjustment, and adapting to the diverse display adjustment needs of software engineering.

[0021] 2. In this invention, the symmetrical arrangement of ball bearings and guide channels on the lifting column effectively improves the stability and service life of the equipment. The symmetrically arranged ball bearings can evenly distribute the load, making the force even when the lifting column is raised and lowered vertically, avoiding shaking or shifting of the display board, and ensuring stable display operation. At the same time, the closed U-shaped guide channel, combined with the evenly distributed through holes, can achieve uniform distribution and full coverage of lubricant, effectively reducing friction loss of parts, reducing equipment wear and jamming failures, delaying equipment aging, and significantly improving the overall durability and operational reliability of the device.

[0022] 3. The added positioning mechanism in this invention effectively improves the stability of the display board after adjustment. Through the interlocking of the L-shaped snap-fit ​​plate and the outer positioning plate of the sliding column, the lifting column can be quickly fixed and the height of the display board can be accurately locked. This effectively avoids the problem of the equipment sliding or shifting due to vibration or external force. The structure is easy to operate and has a reliable limit. It complements the automatic lubrication structure. While retaining the advantage of flexible and adjustable display board height, it ensures the long-term stable operation of the equipment and meets the needs of routine display operations in software engineering.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] Please see Figures 1-6 The present invention provides a technical solution:

[0035] An adjustable electronic display board for software engineering includes a stabilizing plate 1, a sliding column 2 fixedly connected to the top of the stabilizing plate 1, a lifting column 3 slidably engaged inside the sliding column 2, a display board body 4 fixedly connected to the top of the lifting column 3, and a pushing and lubricating mechanism 5 provided between the sliding column 2 and the lifting column 3.

[0036] The side wall of the lifting column 3 is provided with a rotating groove 31, the inside of the rotating groove 31 is provided with a ball 32, the inside of the lifting column 3 is provided with a U-shaped guide groove 33, and a through hole 34 is provided between the U-shaped guide groove 33 and the rotating groove 31.

[0037] The lubrication mechanism 5 includes an electric telescopic rod 51, a push rod 52 fixedly connected to the top of the electric telescopic rod 51, a sliding rod 53 fixedly connected to the outside of the push rod 52, a moving groove 54 opened in the side wall of the sliding column 2, a nylon rod 55 movably engaged in the inner bottom wall of the moving groove 54, a return spring 56 sleeved on the nylon rod 55, a pressing plate 57 fixedly connected to the outside of the sliding rod 53, a pressing rod 58 fixedly connected to the top of the tail end of the sliding rod 53, a lubricant sac 59 fixedly connected to the outside of the sliding column 2, a telescopic conduit 510 fixedly connected to the top of the lubricant sac 59, and an oil guide pipe 511 fixedly connected to the top of the telescopic conduit 510.

[0038] It should be noted that: the rotating grooves 31 are symmetrically distributed on both sides of the lifting column 3, the balls 32 are evenly distributed inside the rotating grooves 31, and the balls 32 roll tightly against the inner wall of the sliding column 2, the two ends of the U-shaped guide groove 33 are blocked, and the U-shaped guide groove 33 is located outside the rotating groove 31, the through holes 34 are evenly distributed between the U-shaped guide groove 33 and the rotating groove 31, the electric telescopic rod 51 is fixedly connected to the inner bottom wall of the sliding column 2, the top of the push rod 52 is fixedly connected to the bottom of the lifting column 3, the sliding rod 53 is symmetrically distributed outside the push rod 52, and the tail end of the sliding rod 53 is located outside the sliding column 2, the top of the nylon rod 55 is fixedly connected to the top of the sliding rod 53, the sliding rod 53 is slidably connected inside the moving groove 54, the squeezing rod 58 is located below the lubricant bladder 59, and the end of the oil guide tube 511 away from the telescopic guide tube 510 is fixedly connected inside the U-shaped guide groove 33.

[0039] Furthermore: the stabilizing plate 1 serves as the base of the entire machine, supporting all the components above and ensuring that the equipment is placed stably and does not tip over; the sliding column 2 and the lifting column 3 are nested together to form the lifting body, and the top of the lifting column 3 is equipped with the display board body 4. The height of the display board can be adjusted by the relative sliding of the two; a push lubrication mechanism 5 is provided between the sliding column 2 and the lifting column 3 to provide continuous lubrication support for the lifting and lowering parts and reduce frictional losses during lifting and lowering.

[0040] Specifically: Rotating grooves 31 are symmetrically opened on both sides of the lifting column 3, and rolling balls 32 are evenly assembled in the grooves. The rolling balls 32 roll against the inner wall of the sliding column 2 to replace hard friction and reduce lifting resistance. The symmetrically arranged rolling balls 32 can also evenly distribute the weight of the display panel body 4, limit the lateral displacement of the lifting column 3, and improve the coaxiality and stability of the lifting and telescopic process. The lifting column 3 has a U-shaped guide groove 33 with closed ends inside for storing lubricating medium. There are through holes 34 between the U-shaped guide groove 33 and the rotating groove 31, which can divert and deliver lubricating oil to each contact surface of the rolling ball 32 to achieve uniform oil supply throughout the entire area.

[0041] Simultaneously: The electric telescopic rod 51 inside the lubrication mechanism 5 is fixed inside the sliding column 2 as a lifting drive component. The linkage push rod 52 drives the lifting column 3 to complete the lifting action. Sliding rods 53 are symmetrically fixed on both sides of the push rod 52. The sliding rods 53 are inserted into the moving grooves 54 on the side wall of the sliding column 2. The moving grooves 54 provide a vertical sliding track for the sliding rods 53, constraining the movement trajectory of the sliding rods 53, so that the lifting action and the lubrication extrusion action are synchronized.

[0042] As a further implementation of this solution, a positioning mechanism 6 is also provided between the sliding column 2 and the lifting column 3. The positioning mechanism 6 includes a hinge plate 61, a connecting rod 62 is provided on the outside of the hinge plate 61, an L-shaped snap-fit ​​plate 63 is fixedly connected to the outside of the connecting rod 62, and a positioning plate 64 is fixedly connected to the outside of the sliding column 2.

[0043] It should be noted that: the hinge plates 61 are symmetrically distributed on the outside of the lifting column 3, the positioning plates 64 are evenly and symmetrically distributed on the outside of the sliding column 2, and the bottom of the L-shaped snap-fit ​​plate 63 is snapped between the two positioning plates 64.

[0044] Furthermore: a nylon rod 55 is fitted at the bottom of the moving groove 54, and the upper end of the nylon rod 55 is connected to the sliding rod 53. A return spring 56 is fitted on the rod body. The nylon material can reduce sliding friction noise. The return spring 56 is responsible for the downward return of the sliding rod 53. The outer side of the sliding rod 53 is fitted with the inner wall of the moving groove 54 to prevent the sliding rod 53 from shaking. A pressing rod 58 is set at the top of the extended end of the sliding rod 53 to press the lubricant bladder 59 to output lubricating oil.

[0045] Specifically: the lubricant bladder 59 is fixed on the outside of the sliding column 2 to store sufficient lubricating oil. When squeezed, the grease inside is transported through the telescopic conduit 510. The telescopic conduit 510 can adapt to the lifting stroke and produce telescopic deformation, so that the pipeline will not be pulled and broken. The oil guide pipe 511 connects the telescopic conduit 510 and the U-shaped guide groove 33 to form a complete oil supply channel, which stably guides the lubricating oil into the guide structure inside the lifting column 3 to realize the directional delivery of the lubricating medium.

[0046] Meanwhile, a positioning mechanism 6 is added to the outside of the sliding column 2 and the lifting column 3. A hinge plate 61 is symmetrically arranged on the outside of the lifting column 3. The hinge plate 61 is connected to the L-shaped locking plate 63 through the connecting rod 62. The hinge structure allows the L-shaped locking plate 63 to be freely rotated. Multiple sets of positioning plates 64 are evenly arranged on the outer wall of the sliding column 2. After adjusting the height, the L-shaped locking plate 63 is inserted into the middle of the two positioning plates 64 to lock the relative position of the sliding column 2 and the lifting column 3, preventing the display board body 4 from sliding down and shifting during use, and improving the fixed reliability of the equipment after adjustment.

[0047] Work process: During equipment height adjustment, the electric telescopic rod 51 fixed to the inner bottom wall of the sliding column 2 serves as a power source to output telescopic power, driving the top push rod 52 to perform vertical pushing and pulling actions. Since the top of the push rod 52 is fixedly connected to the bottom of the lifting column 3, when the electric telescopic rod 51 extends, it can push the lifting column 3 to slide upward along the inner wall of the sliding column 2, thereby raising the display panel body 4; when the electric telescopic rod 51 retracts, it can pull the lifting column 3 downward, completing the height adjustment of the display panel body 4. The lifting column 3 has symmetrical rotating grooves 31 on both sides, and the evenly arranged balls 32 in the grooves always roll and fit against the inner wall of the sliding column 2. During the up and down sliding of the lifting column 3, the balls 32 convert the surface friction between the lifting column 3 and the sliding column 2 into rolling friction, greatly reducing the resistance to lifting and adjusting. At the same time, the symmetrically arranged balls 32 on both sides can evenly bear the load of the display panel body 4 and the lifting column 3, preventing the lifting column 3 from shifting or tilting, and ensuring that the height adjustment process is smooth and stable.

[0048] While the equipment is being raised and lowered, it can also perform automatic lubrication operations. Relying on the lubrication mechanism 5, it achieves precise quantitative supply of lubricating medium. During the vertical movement of the push rod 52, the sliding rod 53, which is symmetrically fixed on its outer side, slides vertically along the moving groove 54 on the side wall of the sliding column 2 in sync with the push rod 52. The tail of the sliding rod 53 drives the top squeezing rod 58 to move up and down in sync. The squeezing rod 58 is correspondingly set below the lubricant bladder 59. When the lifting column 3 rises and the sliding rod 53 moves up, the squeezing rod 58 pushes the lubricant bladder 59 upward, causing the inside of the lubricant bladder 59 to be compressed and contracted. The lubricant inside the bladder is introduced into the oil guide pipe 511 through the telescopic conduit 510 and finally delivered to the closed U-shaped guide groove 33 inside the lifting column 3. The two ends of the U-shaped guide groove 33 are sealed to prevent lubricant leakage. The through holes 34 evenly distributed between the groove and the rotating groove 31 can evenly distribute and penetrate the lubricant to each ball 32 and the rolling contact surface, achieving uniform lubrication in the whole area and effectively reducing friction and wear.

[0049] After a single lubrication is completed, as the electric telescopic rod 51 retracts, it drives the sliding rod 53 downward. The squeezing rod 58 disengages from the lubricant bladder 59, releasing the squeezing limit. At this time, the return spring 56 sleeved on the outside of the nylon rod 55 releases its elastic potential energy, pulling the sliding rod 53 to reset, so that the overall lubrication structure returns to its initial state, waiting for the next lifting action to link with lubrication, forming a cyclic automatic lubrication process. There is no need for manual periodic addition of lubricating oil, which continuously ensures the smoothness of the lifting structure and avoids problems such as jamming, dryness, abnormal noise and component aging and wear after long-term use. Among them, the nylon rod 55 is movably engaged in the inner bottom wall of the moving groove 54, and the sliding rod 53 is slidably connected inside the moving groove 54 throughout the entire process, ensuring stable reset sliding without deviation.

[0050] Once the display panel body 4 is adjusted to the required working height, the height can be locked and fixed by the positioning mechanism 6. The hinge plates 61 symmetrically arranged on the outside of the lifting column 3, together with the connecting rod 62, can drive the L-shaped locking plate 63 to rotate and align flexibly. Multiple sets of positioning plates 64 evenly and symmetrically distributed on the outside of the sliding column 2 form multi-level limiting points. The operator can lock the bottom of the L-shaped locking plate 63 between the two sets of positioning plates 64 at the corresponding height. By using the limiting and blocking effect of the positioning plate 64, the relative sliding between the lifting column 3 and the sliding column 2 is restricted, and the height of the display panel body 4 is accurately locked. This locking and positioning method has a stable structure and is easy to operate. It can effectively offset the displacement caused by vibration and external force during the operation of the equipment, prevent the display panel body 4 from sliding down or shifting, and ensure that the display panel body 4 always maintains a stable state during operation. It is suitable for long-term and stable display operation scenarios in software engineering.
