Description

Technical Field

[0001] This utility model relates to the field of exhibition hall display equipment technology, and in particular to a modular intelligent box structure for exhibition hall content that can be flexibly assembled. Background Technology

[0002] In the construction and use of modern exhibition halls, modular smart boxes serve as an important carrier of display content, and the structural security and assembly flexibility of these boxes are of paramount importance.

[0003] When using existing modular box structures, the corners of the boxes are easily damaged by collisions during handling and assembly, affecting their service life. At the same time, different display scenarios have different requirements for the size and layout of the boxes, and traditional structures are difficult to adjust flexibly, and the heat dissipation effect is poor, affecting the normal operation of internal equipment.

[0004] Therefore, this utility model proposes a modular intelligent box structure for exhibition hall content that can be flexibly assembled. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular intelligent box structure for exhibition hall content that can be flexibly assembled.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular intelligent box structure for exhibition hall content that can be flexibly assembled, including a projection box mechanism, and further including corner protection fixing components at the four corners of the projection box mechanism;

[0007] The telescopic adjustment assembly consists of a protective mounting plate disposed between the two corner guard fixing assemblies and telescopic rods. There are four telescopic rods in total, and the four telescopic rods are arranged in pairs symmetrically with each other at the center of the protective mounting plate. The ends of the four telescopic rods away from the protective mounting plate are rotatably connected to threaded sleeves.

[0008] Furthermore, the protective mounting plate is provided with two heat dissipation holes, which are symmetrical about the center of the protective mounting plate.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: The heat dissipation holes of the protective mounting plate are designed based on the principle of thermal convection. Utilizing the temperature difference generated during the operation of the projection box mechanism, air is driven through symmetrically distributed holes to form a circulating airflow. When the internal equipment heats up, hot air is discharged from the upper heat dissipation holes, and cool air is drawn in from the lower holes, forming a "chimney effect." Combined with the passive heat dissipation structure inside the projection box mechanism, efficient heat dissipation is achieved. The symmetrical layout ensures a balanced airflow path and avoids localized heat accumulation.

[0010] Furthermore, the corner protector fixing assembly consists of a snap-fit ​​plate and threaded rods. The snap-fit ​​plate has a right-angle structure, and there are four threaded rods in total. The four threaded rods are arranged in pairs on the horizontal and vertical ends of the snap-fit ​​plate, respectively.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: the corner fixing component, through the L-shaped structure of the right-angle snap-fit ​​plate, closely fits the right-angle corner of the projection box mechanism. By utilizing the opposing pre-tightening force of the two sets of threaded rods, the snap-fit ​​plate is rigidly fixed to the box. During installation, a torque wrench is used to apply a tightening force to the threaded rods, causing the rubber pads on the surface of the snap-fit ​​plate and the box to undergo elastic deformation, forming a dual effect of friction fixing and buffering. The mechanical transmission path of the right-angle structure is short, which can decompose the impact force into compressive stress along the axial direction of the threaded rod and shear stress on the plane of the snap-fit ​​plate.

[0012] Furthermore, a rubber pad is provided between the snap-fit ​​plate and the projection box mechanism, and the size of the rubber pad is adapted to the size of the snap-fit ​​plate.

[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: The rubber pad utilizes the viscoelastic properties of polymer materials to form a flexible buffer layer between the snap-fit ​​plate and the projection box mechanism. When the box is impacted, the rubber pad absorbs the impact energy through the stretching and twisting of molecular chain segments and slowly releases the impact force as heat energy. Its size is perfectly matched with the snap-fit ​​plate to ensure uniform pressure on the contact surface and avoid stress concentration caused by rigid contact. At the same time, the surface roughness of the rubber pad increases the friction force, which helps the snap-fit ​​plate maintain a fixed position.

[0014] Furthermore, the threaded sleeve and the threaded rod are connected by a thread, and the length of the threaded sleeve is greater than the length of the threaded rod.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the threaded sleeve and the threaded rod form an adjustable threaded pair, which utilizes the redundant length of the sleeve to achieve the dual functions of pre-tightening and adjustment. When the threaded sleeve is rotated, its inner wall thread meshes with the outer wall thread of the threaded rod. The effective length of the telescopic rod is changed by axial displacement. The sleeve length is greater than the threaded rod, which ensures that the threaded rod is always inside the sleeve during the adjustment process, avoiding the exposed thread end from causing bumps or loosening. At the same time, a "sleeve protective cover" structure is formed to enhance the resistance of the connection node to external impact.

[0016] Furthermore, a right-angle mounting plate is provided on the protective mounting plate at the bottom of the projection box mechanism, and there are two right-angle mounting plates in total.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: The right-angle mounting plate of the bottom protective mounting plate adopts an L-shaped metal plate structure, which is rigidly connected to the display stand or the ground by bolts. The two mounting plates are diagonally distributed. Utilizing the principle of triangle stability, the shear force and overturning moment at the bottom of the box are converted into the axial tensile force of the bolts and the frictional force of the mounting surface. During installation, the right-angle mounting plate is fixed by expansion bolts or magnetic bases, so that the vertical line of the center of gravity of the projection box mechanism always falls within the support area formed by the two mounting plates.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, the telescopic adjustment component is connected to the threaded rod of the corner protection fixing component through a threaded sleeve to form an adjustable rigid support structure. When the threaded sleeve is rotated, based on the thread transmission principle, the telescopic rod moves linearly along the axial direction to achieve precise adjustment of the distance between adjacent projection box mechanisms. The protective mounting plate acts as a force transmission hub, and balances the lateral stress through two sets of symmetrically distributed telescopic rods to ensure structural stability.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a modular intelligent box structure for exhibition hall content that can be flexibly assembled, including a projection box mechanism 1, and also including corner protection fixing components 2 at the four corners of the projection box mechanism 1.

[0031] The telescopic adjustment assembly 3 consists of a protective mounting plate 31 positioned between two corner guard fixing assemblies 2 and four telescopic rods 32. These four telescopic rods 32 are arranged in pairs, symmetrically positioned around the center of the protective mounting plate 31. Each of the four telescopic rods 32 has a threaded sleeve 33 rotatably connected to its end away from the protective mounting plate 31. The telescopic adjustment assembly 3 is threadedly connected to the threaded rod 22 of the corner guard fixing assembly 2 via the threaded sleeve 33, forming an adjustable rigid support structure. When the threaded sleeve 33 is rotated, based on the threaded transmission principle, the telescopic rods 32 move linearly along the axial direction, achieving precise adjustment of the distance between adjacent projection box mechanisms 1. The protective mounting plate 31 acts as a force transmission hub, balancing lateral stress through the two symmetrically distributed sets of telescopic rods 32 to ensure structural stability.

[0032] The protective mounting plate 31 has two heat dissipation holes 311, which are symmetrical about the center of the protective mounting plate 31. The heat dissipation holes 311 are designed based on the principle of thermal convection. Utilizing the temperature difference generated during the operation of the projection box mechanism 1, air is driven through the symmetrically distributed holes to form a circulating airflow. When the internal equipment heats up, hot air is exhausted from the upper heat dissipation hole 311, and cool air is drawn in from the lower hole, creating a "chimney effect." Combined with the passive heat dissipation structure inside the projection box mechanism 1, this achieves efficient heat removal. The symmetrical layout ensures a balanced airflow path and avoids localized heat accumulation.

[0033] 2 consists of a snap-fit ​​plate 21 and threaded rods 22. The snap-fit ​​plate 21 has a right-angle structure. There are four threaded rods 22 in total, and the four threaded rods 22 are arranged in pairs on the horizontal and vertical ends of the snap-fit ​​plate 21 respectively. The corner fixing assembly 2 fits tightly with the right-angle corner of the projection box mechanism 1 through the L-shaped structure of the right-angle snap-fit ​​plate 21. The snap-fit ​​plate 21 is rigidly fixed to the box by the opposing pre-tightening force of the two sets of threaded rods 22. During installation, the threaded rods 22 are tightened by a torque wrench, which causes the rubber pads 23 on the surface of the box to undergo elastic deformation, forming a dual function of friction fixing and buffering. The mechanical transmission path of the right-angle structure is short, which can decompose the impact force into compressive stress along the axial direction of the threaded rods 22 and shear stress on the plane of the snap-fit ​​plate 21.

[0034] A rubber pad 23 is provided between the snap-fit ​​plate 21 and the projection box mechanism 1. The size of the rubber pad 23 is adapted to the size of the snap-fit ​​plate 21. The rubber pad 23 utilizes the viscoelastic properties of polymer materials to form a flexible buffer layer between the snap-fit ​​plate 21 and the projection box mechanism 1. When the box is impacted, the rubber pad 23 absorbs the impact energy through the stretching and twisting of molecular chain segments and slowly releases the impact force as heat energy. Its size is perfectly adapted to the snap-fit ​​plate 21 to ensure uniform pressure on the contact surface and avoid stress concentration caused by rigid contact. At the same time, the surface roughness of the rubber pad 23 increases the friction force and helps the snap-fit ​​plate 21 maintain a fixed position.

[0035] The threaded sleeve 33 and the threaded rod 22 are connected by threads. The length of the threaded sleeve 33 is greater than the length of the threaded rod 22. The threaded sleeve 33 and the threaded rod 22 form an adjustable threaded pair. The redundant length of the sleeve realizes the dual functions of pre-tightening and adjustment. When the threaded sleeve 33 is rotated, its inner wall thread engages with the outer wall thread of the threaded rod 22. The effective length of the telescopic rod 32 is changed by axial displacement. The sleeve length is greater than the threaded rod 22, which ensures that the threaded rod 22 is always inside the sleeve during the adjustment process, avoiding the exposed thread end from being bumped or loosened. At the same time, a "sleeve protective cover" structure is formed to enhance the resistance of the connection node to external impact.

[0036] Two right-angle mounting plates 34 are provided on the protective mounting plate 31 at the bottom of the projection box mechanism 1. The right-angle mounting plates 34 of the bottom protective mounting plate 31 adopt an L-shaped metal plate structure and are rigidly connected to the display stand or the ground by bolts. The two mounting plates are diagonally distributed. Utilizing the principle of triangle stability, the shear force and overturning moment at the bottom of the box are converted into the axial tensile force of the bolts and the friction force of the mounting surface. During installation, the right-angle mounting plates 34 are fixed by expansion bolts or magnetic bases, so that the vertical line of the center of gravity of the projection box mechanism 1 always falls within the support area formed by the two mounting plates.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
