Intelligent digital exhibition hall interactive display device and use method

Abstract

The present invention relates to the field of interactive display equipment, and discloses an intelligent digital exhibition hall interactive display device and a method for using the same. In the present invention, there is a gap between a limit card plate and a fixed plate and reinforcing ribs. The design of the gap allows a movable card plate to be inserted into the gap during installation and form multi-point contact with the fixed plate and the reinforcing ribs. This multi-point contact design effectively disperses the weight of the display screen and avoids excessive pressure on the supporting structure caused by weight concentration. By dispersing the weight, the contact area between the movable card plate and the supporting device is increased, thereby providing a more stable support, ensuring that the display screen can be firmly installed on the wall. In addition, due to the multi-point contact and fastening between the movable card plate and the fixed plate and the reinforcing ribs, the display screen is more stable after installation. This stability reduces the risk of loosening and skewing due to vibration or other external forces.

Description

Technical Field

[0001] The present invention relates to the field of interactive display equipment, and in particular to an intelligent digital exhibition hall interactive display device and a use method thereof. Background Art

[0002] The intelligent digital exhibition hall interactive display device is an integrated display screen with interactive functions, which is mainly used to display or expose relevant component information or corresponding content with Internet of Things functions. In the existing intelligent digital exhibition hall, it is generally suspended and fixed by a mechanical cantilever installed on the wall, and this fixing method is only suitable for smaller display devices. When fixing a larger display device, the mechanical cantilever often cannot effectively support the display device due to the increase in the mass of the display device, resulting in the skew of the display device, and it is also easy to cause the fixing end of the mechanical cantilever and the wall to become loose. Summary of the invention

[0003] The present invention provides an intelligent digital exhibition hall interactive display device and a use method, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] An intelligent digital exhibition hall interactive display device comprises a display device body and a movable bracket, wherein the display device body is mounted on a wall, and the movable bracket is supported at the lower end of the display device body;

[0006] The display device body includes a display screen and a support device. The display screen is fixed at one end of the support device, and the support device is installed on a wall. A movable card is movably installed on the side of the support device facing the display screen, and a fixed plate and a reinforcing rib are arranged at the corresponding positions of the display screen and the movable card. The fixed plate and the reinforcing rib are stepped structures, and a limiting card is arranged at the end of the side of the reinforcing rib, and there is a gap between the limiting card and the fixed plate and the reinforcing rib. When the display screen is installed on the support device, the movable card is respectively against the fixed plate and the reinforcing rib, and the movable card is inserted into the gap between the limiting card and the fixed plate and the reinforcing rib.

[0007] The reinforcing rib surface is provided with a through hole 1, and the movable card plate surface is provided with a through hole 2, and the through hole 1 and the through hole 2 form a bolt hole. When the display screen is installed on the supporting device, a bolt passes through the bolt hole to fix the movable card plate and the fixed plate;

[0008] The support device includes a telescopic column and a fixing assembly, wherein a spherical clamping bead is arranged at one end of the telescopic column close to the movable clamping plate, and a spherical groove column is arranged at a corresponding position between the movable clamping plate and the spherical clamping bead, and the spherical clamping bead is movably installed in the spherical groove column;

[0009] The side surfaces of the telescopic column are respectively connected to the side surfaces of the movable card plate through a plurality of telescopic support rods. When the movable card plate swings, the telescopic support rods in the corresponding directions are squeezed or extended.

[0010] The telescopic support rod includes a sleeve and a movable rod. The sleeve is provided with a threaded hole, and the sleeve is respectively sleeved on the left and right ends of the movable rod. The surfaces of both ends of the movable rod are provided with threads, and are respectively threadedly connected with the corresponding threaded holes in the sleeve. The movable rod is tightly fitted with the surface of the threaded hole, and the threaded hole is connected to the outside through an exhaust port.

[0011] The ends of the two sleeves are connected to the movable clamping plate and the surface of the telescopic column through a connecting piece, and the two connecting pieces are connected to the corresponding sleeves through a rotating shaft.

[0012] The fixing assembly includes an embedding tube and a stabilizing plate. The embedding tube is connected to a side of the stabilizing plate close to the wall. When the stabilizing plate is installed on the wall, the embedding tube is inserted into the wall. A plurality of rivets are also provided on the surface of the stabilizing plate. The rivets extend toward the side of the stabilizing plate close to the wall and are embedded in the wall.

[0013] A wall embedded tube is provided in the stabilizing plate, and the wall embedded tube extends to the surface of the side of the stabilizing plate away from the wall. The telescopic column is inserted into the wall embedded tube and abuts against the inner side of the wall embedded tube. The wall embedded tube consists of sections one and two. Section two is provided on the side close to the stabilizing plate, and the telescopic column slides in section two. Section one is connected to the surface of the stabilizing plate through rivets provided on the side of the embedded tube, so that when the telescopic column telescopes and slides in the wall embedded tube and creates positive and negative pressure, air flows through the exhaust pipe.

[0014] A preferred technical solution, the movable bracket includes a support plate and a support wheel, the support wheel is arranged on the side of the lower end of the support plate, and the support plate supports the display screen through a support bar arranged on its upper end, the surface of the support bar is provided with an inwardly concave card slot, and the display screen is arranged against the surface of the card slot;

[0015] The card slot consists of two curved surfaces and a flat surface, the two curved surfaces are respectively arranged on both sides of the flat surface, and the cross-sectional thickness of the display screen is equal to the width of the flat surface, so that when the display screen is supported by the support plate, the lower end of the display screen can move in the card slot.

[0016] A method for using an intelligent digital exhibition hall interactive display device, which is used to implement the method for using the intelligent digital exhibition hall interactive display device. When in use, the display screen is supported by a supporting device and fixed to a wall, and the balance is maintained;

[0017] When in use, the display screen is supported and kept balanced by the supporting device, and the bottom of the display screen is supported by the movable bracket on the basis of fixing the display screen on the wall by the supporting device;

[0018] When the display screen is pushed to swing along the connection end of the spherical card bead and the spherical slot column, the card slot arranged at the upper end of the support bar provides the display screen with a corresponding movable distance and supporting effect.

[0019] A preferred technical solution is that the display screen can be supported by a supporting device or by a movable bracket. When the display screen supported only by the movable bracket needs to be installed on the supporting device for support by the supporting device, the display screen needs to be moved to be flush with the movable card plate, and the movable card plate needs to be inserted into the gap between the limit card plate and the fixed plate and the reinforcing ribs, and then the bolts are inserted into the bolt holes to fix the movable card plate and the reinforcing ribs.

[0020] Compared with the prior art, this technical solution has the following advantages:

[0021] In the present invention, there is a gap between the limiting card plate and the fixed plate and the reinforcing ribs. The design of the gap allows the movable card plate to be inserted into the gap during installation and form multi-point contact with the fixed plate and the reinforcing ribs. This multi-point contact design effectively disperses the weight of the display screen and avoids excessive pressure on the supporting structure caused by weight concentration. By dispersing the weight, the contact area between the movable card plate and the supporting device is increased, thereby providing a more stable support, ensuring that the display screen can be firmly installed on the wall, and due to the multi-point contact and fastening between the movable card plate and the fixed plate and the reinforcing ribs, the display screen is more stable after installation. This stability reduces the risk of loosening and skewing due to vibration or other external forces. At the same time, due to the effective dispersion of weight, the pressure on the supporting structure is reduced, reducing the possibility of damage or deformation due to long-term use.

[0022] During the extension and retraction process, the sleeve serves as a fixed part, and its position remains unchanged relative to the telescopic column and the movable clamping plate. When the movable rod is extended and retracted in the sleeve, the threaded hole inside the sleeve and the thread of the movable rod move relative to each other, but always maintain a tight bite state. The movable rod is the main extension and retraction part of the telescopic support rod. During the extension and retraction process, the movable rod rotates and retracts in the threaded hole of the sleeve through the threads at both ends of the movable rod. When the movable rod is extended, it increases the overall length of the telescopic support rod, thereby adapting to a larger distance between the display screen and the supporting structure. During the extension and retraction process, the exhaust port allows the air in the sleeve to be discharged or inhaled when the threaded hole and the movable rod move relative to each other, thereby avoiding the smoothness of the extension and retraction being affected by changes in air pressure.

[0043] like Figures 1 to 10As shown, the present invention proposes an intelligent digital exhibition hall interactive display device, comprising a display device body 1 and a movable bracket 2, wherein the display device body 1 is mounted on a wall, and the movable bracket 2 is supported at the lower end of the display device body 1;

[0044] The display device body 1 includes a display screen 11, and the display screen 11 is fixed to one end of a supporting device 12, and the supporting device 12 is installed on a wall. A movable card plate 121 is movably installed on the side of the supporting device 12 facing the display screen 11, and a fixed plate 111 and a reinforcing rib 112 are provided at the corresponding positions of the display screen 11 and the movable card plate 121. The fixed plate 111 and the reinforcing rib 112 are stepped structures, and a limiting card plate 113 is provided at the end of the side of the reinforcing rib 112, and there is a gap between the limiting card plate 113 and the fixed plate 111 and the reinforcing rib 112. When the display screen 11 is installed on the supporting device 12, the movable card plate 121 is respectively against the fixed plate 111 and the reinforcing rib 112, and the movable card plate 121 is inserted into the gap between the limiting card plate 113 and the fixed plate 111 and the reinforcing rib 112;

[0045] The design of the gap allows the movable card plate 121 to be inserted into it during installation, and to form multi-point contact with the fixed plate 111 and the reinforcing ribs 112. This multi-point contact design effectively disperses the weight of the display screen 11, avoiding excessive pressure on the supporting structure caused by weight concentration. By dispersing the weight, the contact area between the movable card plate 121 and the supporting device 12 is increased, thereby providing a more stable support, ensuring that the display screen 11 can be firmly installed on the wall. In addition, due to the multi-point contact and fastening between the movable card plate 121 and the fixed plate 111 and the reinforcing ribs 112, the display screen 11 is more stable after installation. This stability reduces the risk of loosening and skewing caused by vibration or other external forces. At the same time, due to the effective dispersion of weight, the pressure on the supporting structure is reduced, reducing the possibility of damage or deformation caused by long-term use.

[0046] The design of the gap makes the installation and disassembly process of the display screen 11 more convenient. During installation, you only need to align the movable card plate 121 with the gap and insert it, and then fix it by appropriate fastening methods. This design simplifies the installation steps and reduces installation time and labor costs. Similarly, when the display screen 11 needs to be disassembled, you only need to pull the movable card plate 121 out of the gap and then perform necessary disassembly work. This convenient installation and disassembly method improves work efficiency and makes replacement or maintenance of the display screen easier.

[0047] Furthermore, a through hole one is provided on the surface of the reinforcing rib 112, and a through hole two is provided on the surface of the movable clamping plate 121. The through hole one and the through hole two constitute a bolt hole. When the display screen 11 is installed on the supporting device 12, a bolt 1212 passes through the bolt hole to fix the movable clamping plate 121 and the fixed plate 111. The supporting device 12 includes a telescopic column 122 and a fixing assembly 123. A spherical clamping bead 1221 is provided at one end of the telescopic column 122 close to the movable clamping plate 121, and a spherical groove column 1211 is provided at the corresponding position of the movable clamping plate 121 and the spherical clamping bead 1221. The spherical clamping bead 1221 is movably installed in the spherical groove column 1211.

[0048] In addition, the side surfaces of the telescopic column 122 are respectively connected to the side surfaces of the movable card plate 121 through a plurality of telescopic support rods 1222. When the movable card plate 121 swings, the telescopic support rods 1222 in the corresponding directions are squeezed or extended.

[0049] The telescopic support rod 1222 includes a sleeve 2221 and a movable rod 2222. The sleeve 2221 is provided with a threaded hole 101, and the sleeve 2221 is respectively sleeved on the left and right ends of the movable rod 2222. The surfaces of both ends of the movable rod 2222 are provided with threads, and they are respectively threadedly connected with the corresponding threaded holes 101 in the sleeve 2221. The movable rod 2222 is tightly fitted with the surface of the threaded hole 101, and the threaded hole 101 is communicated with the outside through an exhaust port 102; the ends of the two sleeves 2221 are respectively connected to the movable card plate 121 and the surface of the telescopic column 122 through a connecting piece 2224, and the two connecting pieces 2224 are respectively connected to the corresponding sleeves 2221 through a rotating shaft 2223;

[0050] During the telescopic process, the sleeve 2221 serves as a fixed part, and its position remains unchanged relative to the telescopic column 122 and the movable card plate 121. When the movable rod 2222 is telescopic in the sleeve 2221, the threaded hole 101 inside the sleeve 2221 and the thread of the movable rod 2222 move relative to each other, but always maintain a tight bite state, and the movable rod 2222 is the main telescopic part of the telescopic support rod 1222. During the telescopic process, the movable rod 2222 rotates and telescopes in the threaded hole 101 of the sleeve 2221 through the threads at both ends. When the movable rod 2222 is extended, it increases the overall length of the telescopic support rod 1222, so that it can adapt to a larger distance between the display screen 11 and the supporting structure. During the telescopic process, the exhaust port 102 allows the air in the sleeve 2221 to be discharged or inhaled when the threaded hole 101 and the movable rod 2222 move relative to each other, thereby avoiding the smoothness of the telescopic movement being affected by the change in air pressure.

[0051] Furthermore, the fixing assembly 123 includes an embedding tube 1231 and a stabilizing plate 1232. The embedding tube 1231 is connected to a side of the stabilizing plate 1232 close to the wall. When the stabilizing plate 1232 is installed on the wall, the embedding tube 1231 is inserted into the wall. A plurality of rivets 2321 are also provided on the surface of the stabilizing plate 1232. The rivets 2321 extend toward the side of the stabilizing plate 1232 close to the wall and are embedded in the wall.

[0052] A wall-embedded tube 2311 is provided in the stabilizing plate 1232, and the wall-embedded tube 2311 extends to the surface of the side of the stabilizing plate 1232 away from the wall. The telescopic column 122 is inserted into the wall-embedded tube 2311 and abuts against the inner side of the wall-embedded tube 2311. The wall-embedded tube 2311 is composed of sections one and two. The section two is arranged on a side close to the stabilizing plate 1232, and the telescopic column 122 slides in the section two. The section one is connected to the surface of the stabilizing plate 1232 through a rivet 2321 arranged on the side of the embedded tube 1231, so that when the telescopic column 122 telescopes and slides in the wall-embedded tube 2311 and creates positive and negative pressures, air flows through the exhaust pipe 2312; the wall-embedded tube 2311 As the sliding track of the telescopic column 122, a stable support structure is provided, which ensures that the telescopic column can maintain linear motion during the telescopic process, avoiding unstable installation problems caused by offset or shaking, and the inner wall of the wall-embedded tube 2311 is designed with a smooth surface to reduce the friction resistance of the telescopic column 122 during the sliding process. This design enables the telescopic column to perform telescopic movement smoothly, thereby improving the overall performance and reliability of the equipment. In addition, when the telescopic column 122 is telescoped in the wall-embedded tube 2311, positive and negative pressures may be generated due to the change in volume. The design of the wall-embedded tube allows these pressures to be balanced to a certain extent through its internal space, thereby reducing the impact on the movement of the telescopic column.

[0053] A preferred technical solution, the movable bracket 2 includes a support plate 21 and a support wheel 22, the support wheel 22 is arranged on the side of the lower end of the support plate 21, and the support plate 21 supports the display screen 11 through a support bar 211 arranged on the upper end thereof, and the surface of the support bar 211 is provided with an inwardly concave card slot 212, and the display screen 11 is arranged against the surface of the card slot 212;

[0054] The slot 212 is composed of two curved surfaces and a flat surface. The two curved surfaces are respectively arranged on both sides of the flat surface. The cross-sectional thickness of the display screen 11 is equal to the width of the flat surface, so that when the display screen 11 is supported by the support plate 21, the lower end of the display screen 11 can move in the slot 212.

[0055] Since the card slot 212 is composed of two curved surfaces and a flat surface, this design enables the card slot to adapt to the shape of the display screen 11 and provide a certain amount of movement space inside the card slot. The two curved surfaces are respectively arranged on both sides of the flat surface. This layout not only increases the contact area between the card slot and the display screen, but also makes the display screen move more smoothly in the card slot through the guiding effect of the curved surface. In addition, the cross-sectional thickness of the display screen 11 is equal to the width of the flat surface in the card slot 212. This design ensures that the display screen can move stably in the card slot without shaking or falling off.

[0056] When the display screen is placed in the card slot, its lower end fits tightly against the flat surface of the card slot, while the two sides are supported and guided by the curved surfaces, thereby achieving stable movement of the display screen in the card slot. Since the card slot 212 has a certain depth and width, this provides a certain movable distance for the display screen 11, and the display screen can move along its length direction in the card slot without being restricted by the card slot. At the same time, the curved surface design of the card slot also plays a certain buffering role, so that the display screen can be more stable and smooth during the movement process, further increasing the feasibility of the movable distance.

[0057] Compared with the above content, the present invention also proposes a method for using the intelligent digital exhibition hall interactive display device, which is used to implement the method for using the intelligent digital exhibition hall interactive display device. When in use, the display screen 11 is supported and fixed to the wall by the supporting device 12, and the balance is maintained;

[0058] When in use, the display screen 11 is supported and balanced by the support device 12, and the bottom of the display screen 11 is supported by the movable bracket 2 on the basis of fixing the display screen 11 on the wall by the support device 12;

[0059] When the display screen 11 is pushed to swing along the connection end between the spherical card bead 1221 and the spherical slot column 1211 , the card slot 212 provided at the upper end of the support bar 211 provides the display screen 11 with a corresponding movable distance and supporting effect.

[0060] Furthermore, the display screen 11 can be supported by the supporting device 12 or by the movable bracket 2. When the display screen 11 supported only by the movable bracket 2 needs to be installed on the supporting device 12 for support by the supporting device 12, the display screen 11 needs to be moved to be flush with the movable card plate 121, and the movable card plate 121 needs to be inserted into the gap between the limiting card plate 113 and the fixed plate 111 and the reinforcing rib 112, and then the bolt 1212 needs to be inserted into the bolt hole to fix the movable card plate 121 and the reinforcing rib 112.

[0061] Based on the above-stated usage method, compared with the shortcomings described in the background technology, it brings significant beneficial effects and forms a sharp contrast with them, as follows:

[0062] Improved support stability of the display screen: The display screen 11 is supported by the support device 12 and fixed to the wall, thereby maintaining the balance of the display screen, and effectively avoiding the problem of unstable support and easy shaking of the display screen mentioned in the background technology;

[0063] Increased mobility and flexibility of the display screen: On the basis of the display screen being fixed on the wall, the bottom of the display screen 11 is further supported by the movable bracket 2, so that the display screen can maintain stability while also having a certain degree of mobility and flexibility, which is convenient for users to adjust the position and angle of the display screen as needed;

[0064] Provides swing support for the display screen: when the display screen 11 is pushed to swing along the connection end between the spherical card bead 1221 and the spherical slot column 1211, the card slot 212 provided at the upper end of the support bar 211 provides the display screen 11 with a corresponding movable distance and support effect. This design enables the display screen to maintain stability while also having a certain swing range, further increasing its flexibility and adaptability;

[0065] The installation and disassembly process of the display screen is simplified: the display screen 11 can be supported by the supporting device 12 or the movable bracket 2. When the display screen needs to be installed from the movable bracket to the supporting device, it only needs to be moved to be flush with the movable card plate 121, and the movable card plate is inserted into the gap between the limiting card plate 113 and the fixed plate 111 and the reinforcing rib 112, and then the bolt 1212 is inserted into the bolt hole to fix it. This design simplifies the installation and disassembly process of the display screen and improves the use efficiency.

[0066] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
