Description

Technical Field

[0001] This application relates to the technical field of display device transportation, and in particular to a transport rack and display screen transportation device. Background Technology

[0002] An LED display screen is an electronic device that displays text, graphics, video, and other information by controlling semiconductor light-emitting diodes (LEDs). It is widely used in advertising, transportation, sports venues, and other fields. From the manufacturing site to the usage site, LED displays need to undergo long-distance transportation. During this process, there are safety hazards such as bumps, collisions, and drops that can cause damage to the LED displays. Therefore, during transportation, LED displays need to be placed in special transport racks to provide protection for the LED displays.

[0003] However, traditional transport racks have complex structural designs and many components, making assembly with LED displays time-consuming, labor-intensive, and inefficient. Furthermore, the transport racks do not provide adequate positioning for the LED displays, and when transported by sea or land over uneven surfaces, they can cause severe shaking of the LED displays, resulting in lateral shifts or vertical jumps, posing a safety hazard of collision damage. Utility Model Content

[0004] Therefore, it is necessary to provide a transport rack and display screen transport device to address the problems of time-consuming and labor-intensive installation and operation, poor limiting effect, and potential safety hazards of collision damage caused by traditional technologies.

[0005] A first aspect of this application provides a transport rack comprising:

[0006] A carrier plate assembly is provided with a first limiting mechanism, which is used to engage with the display screen to limit the degree of freedom of the display screen along the first and second directions of the transport frame.

[0007] A first side railing and a second side railing are spaced apart on the carrier plate assembly along a first direction of the transport frame, and the first side railing, the second side railing, and the carrier plate assembly cooperate to form an installation space for accommodating the display screen; the first side railing and / or the second side railing are provided with a second limiting mechanism, which is used to engage with the display screen to restrict the degree of freedom of the display screen along a third direction of the transport frame;

[0008] The first direction, the second direction, and the third direction are arranged to intersect each other.

[0009] This solution utilizes a transport frame designed to protect and ensure the safety of displays during transport. Specifically, the display is first placed on a carrier assembly and engaged with a first limiting mechanism pre-installed on the carrier assembly. This first limiting mechanism effectively restricts the display's freedom of movement along the first and second directions of the transport frame. Next, the first and second side rails are sequentially or simultaneously installed onto the carrier assembly along the first direction. These three components work together to form an installation space, within which the display is positioned, allowing the transport frame to accommodate and install the display. Once the first and second side rails are fixed in place, the second limiting mechanism pre-installed on the first and / or second side rails engages with the display, further restricting its freedom of movement along the third direction of the transport frame. On the one hand, the carrier plate assembly, the first side railing, and the second side railing surround the display screen, providing protection for the display screen and preventing it from being hit by other objects in the environment. Moreover, the transport frame has a small number of components, making installation convenient and labor-saving, which helps to improve installation efficiency. On the other hand, the first and second limiting mechanisms simultaneously constrain the display screen's degrees of freedom in the first, second, and third directions, thereby achieving more reliable positioning of the display screen. Even during long-distance sea transport or land transport on uneven roads, which may cause the transport frame to shake, the display screen can be effectively limited from lateral displacement or vertical jumping within the transport frame, preventing the display screen from being damaged by impacts and protecting its safety.

[0010] The technical solution of this application will be further described below:

[0011] In one embodiment, the first limiting mechanism includes:

[0012] A first limiting component, located at one end of the carrier plate assembly along the first direction, is used to engage one end of the display screen; and

[0014] In one embodiment, both the first limiting component and the second limiting component include at least two first locking blocks and at least one second locking block. The at least two first locking blocks and at least one second locking block are arranged side by side on the carrier plate assembly along the second direction. A second locking block is arranged between two adjacent first locking blocks, and the two first locking blocks and one second locking block cooperate to form a slot, which is used for the end of the display screen to be inserted and installed.

[0015] In one embodiment, the first and / or the second card blocks are provided with an inlet structure forming the side of the card slot, the inlet structure being used to guide the end of the display screen into the card slot.

One of the connector and the post is provided with a insertion hole, and the connector or the post is detachably inserted into the insertion hole.

[0017] In one embodiment, both the first side fence and the second side fence further include a crossbar connected to the end of the post away from the support plate;

[0018] The second limiting mechanism includes an mounting component and a limiting clip. The limiting clip is mounted on the crossbar via the mounting component. The limiting clip has a locking part for locking the edge of the display screen.

[0019] In one embodiment, the snap-fit ​​portion, the first limiting component, and the second limiting component are each provided with at least two of each other and are provided in a one-to-one correspondence to form at least two limiting structures, and the at least two limiting structures are arranged side by side along the second direction.

[0020] In one embodiment, the transport frame further includes a latch and a hook, the latch being disposed on one of the connecting body and the upright, and the hook being disposed on the other of the connecting body and the upright, the latch and the hook being detachably engaged.

[0021] In one embodiment, the carrier plate assembly further includes a plurality of support feet, which are distributedly mounted on the bottom surface of the carrier plate.

[0022] In one embodiment, the support foot is provided with an inclined surface, and both the first side railing and the second side railing include inclined beams. The inclined beams are adapted to the inclination direction of the inclined surface, so that the inclined surface of one transport frame is wedge-fitted with the inclined beam of the other transport frame, thereby enabling the two transport frames to be stacked and assembled.

[0023] In one embodiment, the carrier assembly further includes a forklift positioning plate disposed on the bottom surface of the carrier plate. The first side railing and the second side railing are spaced apart along the first direction and cooperate to form a clearance opening. When the two transport racks are stacked and assembled, the clearance opening is used to accommodate the forklift positioning plate.

[0024] A second aspect of this application also provides a display screen transport device, comprising:

[0025] At least one display screen; and

[0026] At least one transport frame as described in any of the above embodiments, wherein the at least one display screen is mounted in the transport frame and constitutes a display screen transport module;

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] LED displays need to undergo long-distance transportation, during which there are safety hazards such as bumps, collisions, and drops that can damage the LED displays. Therefore, during transportation, LED displays need to be placed in a dedicated transport frame 100 to provide protection for the LED displays. However, the traditional transport frame 100 has a complex structure and many components, making assembly with the LED displays time-consuming, labor-intensive, and inefficient. Furthermore, the transport frame 100 does not provide adequate restraint for the LED displays. When traveling by sea or land over uneven roads, it can cause severe bumps to the LED displays, resulting in lateral shifts or vertical jumps, posing a safety hazard of impact damage.

[0047] To address the aforementioned issues, this application proposes a structurally optimized transport frame 100. The transport frame 100 is assembled from three components: a carrier plate assembly 10, a first side railing 30, and a second side railing 40, forming an installation space 50. The installation space 50 accommodates the display screen 200, simplifying the structure of the transport frame 100 and making installation more convenient and labor-saving. Simultaneously, the first side railing 30 and the second side railing 40 provide reliable protection for the display screen 200. Furthermore, a first limiting mechanism 20 is designed on the carrier plate assembly 10, and a second limiting mechanism 60 is designed on the first side railing 30 and / or the second side railing 40. The first limiting mechanism 20 and the second limiting mechanism 60 simultaneously engage with the display screen 200, thereby simultaneously constraining the display screen 200's degrees of freedom along the first, second, and third directions of the transport frame 100. This completely and reliably restricts the movement of the display screen 200 within the transport frame 100, preventing damage from impacts during bumpy transport.

[0048] See Figure 1 and Figure 2 This application illustrates a transport rack 100 according to one embodiment. Specifically, Figure 1 A schematic diagram of the assembly structure of the transport frame 100 is shown; Figure 2 A schematic diagram of the exploded structure of the transport frame 100 is shown.

[0049] For example, the transport rack 100 includes a carrier plate assembly 10, a first side railing 30, and a second side railing 40. The carrier plate assembly 10 is the base component of the transport rack 100. In addition to loading and integrating the first side railing 30 and the second side railing 40, it is also used to support the weight of the display screen 200 during transport and to support and position the display screen 200.

[0050] During installation, both the first side fence 30 and the second side fence 40 are positioned above the carrier plate assembly 10.

[0051] A first limiting mechanism 20 is provided on the carrier plate assembly 10. The first limiting mechanism 20 is used to engage with the display screen 200 to limit the degree of freedom of the display screen 200 along the first direction and the second direction of the transport frame 100. A first side railing 30 and a second side railing 40 are provided on the carrier plate assembly 10 at intervals along the first direction of the transport frame 100. The first side railing 30, the second side railing 40 and the carrier plate assembly 10 cooperate to form a receiving space 50, which is used to receive the display screen 200. The first side railing 30 and / or the second side railing 40 are provided with a second limiting mechanism 60. The second limiting mechanism 60 is used to engage with the display screen 200 to limit the degree of freedom of the display screen 200 along the third direction of the transport frame 100.

[0052] The first direction, the second direction, and the third direction are set to intersect in pairs.

[0053] Combination Figure 1 and Figure 3 For example, in this application, the transport rack 100 has an approximate rectangular parallelepiped structure. Therefore, the transport rack 100 has a length direction, a width direction, and a height direction. Optionally, the first direction refers to the length direction of the transport rack 100, corresponding to... Figure 1 and Figure 3 The X-axis in the diagram; the second direction refers to the width direction of the transport frame 100, corresponding to... Figure 1 and Figure 3 The Y-axis in the diagram; the third direction refers to the height direction of the transport frame 100, corresponding to... Figure 1 and Figure 3 The Z-axis in the diagram.

[0054] Understandably, the first side fence 30 and the second side fence 40 are used to form a protective enclosure for the display screen 200 in the X and Y directions, preventing the display screen 200 from being damaged by external forces in the X and Y directions. At the same time, they constrain the degree of freedom of the display screen 200 in the X, Y and Z directions, preventing the display screen 200 from shifting, tipping over and being damaged by collision.

[0055] Of course, in other alternative embodiments, when the transport frame 100 is designed with other shapes and structures, the first direction, the second direction, and the third direction can also be interpreted in other ways, which will not be elaborated here.

[0056] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The transport frame 100 of this solution is used in the transportation of the display screen 200 to provide protection for the display screen 200 and ensure the safety of the display screen 200 during transportation. Specifically, in use, the display screen 200 is first placed on the carrier plate assembly 10, and the display screen 200 is engaged with the first limiting mechanism 20 preset on the carrier plate assembly 10, so that the first limiting mechanism 20 can effectively restrict the degree of freedom of the display screen 200 along the first direction and the second direction of the transport frame 100.

[0057] Next, the first side railing 30 and the second side railing 40 are sequentially or simultaneously installed onto the carrier plate assembly 10 along the first direction. The three components work together to form an installation space 50. At this time, the display screen 200 is located entirely within the installation space 50, thus enabling the transport frame 100 to accommodate and install the display screen 200. After the first side railing 30 and the second side railing 40 are installed and fixed, the second limiting mechanism 60, which is pre-set on the first side railing 30 and / or the second side railing 40, engages precisely with the display screen 200 to restrict the degree of freedom of the display screen 200 along the third direction of the transport frame 100. In this way, the carrier plate assembly 10, the first side railing 30, and the second side railing 40 surround the outer perimeter of the display screen 200, providing support to the display screen 200. The transport frame 100 provides protection, thus preventing the display screen 200 from being collided with other objects in the environment. Furthermore, the transport frame 100 has few components, making installation convenient and labor-saving, which helps improve installation efficiency. On the other hand, by using the first limiting mechanism 20 and the second limiting mechanism 60 to simultaneously constrain the display screen 200's degrees of freedom in the first, second, and third directions, a more reliable positioning of the display screen 200 is achieved. Even during long-distance sea transport or land transport on uneven roads, which may cause the transport frame 100 to shake, the lateral displacement or vertical movement of the display screen 200 within the transport frame 100 can be effectively limited, preventing the display screen 200 from being damaged by impacts and protecting its safety.

[0058] In one embodiment, the first limiting mechanism 20 includes a first limiting component 21 and a second limiting component 22. The first limiting component 21 is located at one end of the carrier plate assembly 10 along the first direction and is used to engage one end of the display screen 200. The second limiting component 22 is located at the other end of the carrier plate assembly 10 along the first direction and is used to engage the other end of the display screen 200.

[0059] Considering that the display screen 200 is typically a rectangular, flat structure, the first limiting component 21 and the second limiting component 22 are aligned in a first direction. Specifically, the first direction corresponds to the length direction of the carrier assembly 10, and also to the length direction of the display screen 200.

[0060] When the display screen 200 is installed onto the carrier assembly 10, one end of the display screen 200 along its length can be first engaged with the first limiting component 21, and then the other end of the display screen 200 along its length can be engaged with the second limiting component 22; alternatively, the display screen 200 can be lowered horizontally, so that the opposite ends of the display screen 200 along its length are simultaneously engaged with the first limiting component 21 and the second limiting component 22. In this way, the first limiting component 21 and the second limiting component 22 can not only securely fix the display screen 200, but also effectively constrain the degree of freedom of the display screen 200 in the X and Y axes.

[0061] More specifically, in an optional embodiment, both the first limiting component 21 and the second limiting component 22 include at least two first locking blocks 20a and at least one second locking block 20b. The at least two first locking blocks 20a and at least one second locking block 20b are arranged side by side on the carrier assembly 10 along the second direction. A second locking block 20b is disposed between two adjacent first locking blocks 20a, and the two first locking blocks 20a and one second locking block 20b cooperate to form a slot 20c, which is used for the end of the display screen 200 to be inserted and installed.

[0062] Because the formed slot 20c is a U-shaped structure in the XY plane, and the upper side of the slot 20c is open, the display screen 200 can be directly lowered from above during installation, allowing both ends of the display screen 200 in the length direction to be easily and quickly snapped into the corresponding slot 20c. The installation method is convenient, labor-saving, and efficient. After being snapped into place, the second locking block 20b of the first limiting component 21 and the second locking block 20b of the second limiting component 22 simultaneously abut against the two end faces of the display screen 200 in the length direction to limit the display screen 200 along the X-axis direction; at the same time, the two second locking blocks 20b of the first limiting component 21 and the second limiting component 22 simultaneously engage the two opposite sides of the display screen 200 in the thickness direction to limit the display screen 200 along the Y-axis direction, ensuring that the display screen 200 will not shift or loosen in the XY plane during transportation.

[0063] Optionally, the first clip 20a and the second clip 20b are made of flexible material to achieve flexible engagement with the display screen 200, avoiding problems such as dents, deformations, and paint damage to the surface of the display screen 200 caused by excessive engagement force.

[0064] Optionally, the first clip 20a and the second clip 20b can be integrally formed with the carrier plate assembly 10, or they can be detachably assembled with the carrier plate assembly 10 by means of threaded connection, snap-fit ​​connection, adhesive bonding, etc., depending on actual needs.

[0065] The first locking block 20a and the second locking block 20b can be any one of a cylinder, a frustum, a cuboid, etc. For example, in this application, both the first locking block 20a and the second locking block 20b adopt a cuboid structure, which can ensure that both have sufficient contact area with the side of the display screen 200, which also has a cuboid structure, thereby improving the effectiveness and reliability of limiting the display screen 200.

[0066] During installation, when the display screen 200 is installed onto the carrier assembly 10 from top to bottom by manual labor or a robotic arm, in order to ensure that the end of the display screen 200 can be more effectively and accurately inserted into the slot 20c, in an optional embodiment, the first locking block 20a and / or the second locking block 20b are used to form an guiding structure 20d on the side of the slot 20c, and the guiding structure 20d is used to guide the end of the display screen 200 into the slot 20c.

[0067] For example, the imported structure 20d can be any structure such as chamfer, fillet, etc. You can choose flexibly according to the actual needs, and there is no specific limitation here.

[0068] Furthermore, based on any of the above embodiments, the carrier plate assembly 10 includes a carrier plate 11, which is a rectangular plate arranged horizontally in the XY plane. A connector 12 is provided protruding upward from the surface of the carrier plate 11. Both the first side fence 30 and the second side fence 40 include a post 30a. One of the connector 12 and the post 30a is provided with a insertion hole, and the connector 12 or the post 30a is detachably inserted into the insertion hole.

[0069] For example, in this application, the connector 12 has a plug-in hole, and the connector 12 can be understood as a cylindrical structure. When the first side fence 30 and the second side fence 40 are installed on the support plate 11, the lower end of the column 30a is aligned with the plug-in hole of the connector 12, and then the first side fence 30 and the second side fence 40 are released and slowly lowered. The lower end of the column 30a inserts into the plug-in hole by itself, so as to achieve the initial installation and positioning of the first side fence 30 and the second side fence 40 with the support plate 11.

[0070] Optionally, both the first side fence 30 and the second side fence 40 in this application include four posts 30a, which are arranged in a rectangular structure in the XY plane. The rectangle formed by the four posts 30a of the first side fence 30 is open on one side facing the second side fence 40, while the other three sides are equipped with reinforcing bars. These reinforcing bars are connected to two adjacent sets of posts 30a to improve the overall structural strength and stability of the first side fence 30. The second side fence 40 adopts the same structural design as the first side fence 30, and therefore will not be described in detail here.

[0071] To achieve a lightweight design for the transport frame 100, the uprights 30a are made of either round or square tubing. Each upright 30a is connected and fixed to the reinforcing rod by welding to ensure structural strength.

[0072] Furthermore, based on the above embodiments, both the first side fence 30 and the second side fence 40 also include a horizontal bar 30b, which is connected to the end of the upright 30a away from the bearing plate 11. Specifically, the horizontal bar 30b is connected to the upper end of the upright 30a. The horizontal bar 30b and the upright 30a can be an integral structure or a detachable installation structure, whichever is more flexible.

[0073] The second limiting mechanism 60 includes an mounting component and a limiting clip 61. The limiting clip 61 is mounted on the crossbar 30b via the mounting component. The limiting clip 61 has a snap-fit ​​part 611, which is used to snap-fit ​​the edge of the display screen 200.

[0074] The limiting clip 61 can be securely and reliably installed on the crossbar 30b via the mounting component. After the display screen 200 is installed onto the carrier plate assembly 10 via the first limiting mechanism 20, the first side railing 30 and the second side railing 40 are installed onto the carrier plate assembly 10. The limiting clip 61 automatically aligns with and engages with the upper side of the display screen 200, thereby pressing and positioning the display screen 200 on the carrier plate 11. This achieves the effect of limiting the degree of freedom of movement of the display screen 200 along the Z-axis on the transport frame 100, preventing it from jumping up and down due to bumps during transportation, avoiding collision damage, and protecting the appearance and structural safety of the display screen 200.

[0075] For example, the mounting component can be a threaded part, so that the limiting clip 61 can be installed and fixed to the crossbar 30b by a threaded connection; or the mounting component can be an adhesive part, so that the limiting clip 61 can be installed and fixed to the crossbar 30b by an adhesive connection, and so on. These mounting methods are simple in structure, highly feasible, and have good connection reliability.

[0076] Optionally, to avoid damage to the display screen 200 due to excessive clamping force, the limiting clip 61 is made of a flexible material, such as any one of rubber, cotton, or plastic.

[0077] In addition, to further improve the installation strength of the first side fence 30 and the second side fence 40 with the carrier plate assembly 10, and to prevent the first side fence 30 and the second side fence 40 from loosening during transportation and affecting the limiting and restraining effect on the display screen 200, while also facilitating the disassembly and separation of the first side fence 30 and the second side fence 40 from the carrier plate assembly 10 so that the display screen 200 can be quickly taken out of the transport rack 100 after being transported to the destination, in an optional embodiment, the transport rack 100 further includes a latch 70 and a hook 70a. The latch 70 is disposed on one of the connecting body 12 and the column 30a, and the hook 70a is disposed on the other of the connecting body 12 and the column 30a. The latch 70 and the hook 70a are detachably engaged.

[0078] Specifically, the latch 70 uses a latch lock, which has a simple structure and usage, low cost, and low maintenance difficulty.

[0079] Furthermore, based on any of the above embodiments, the latching part 611, the first limiting component 21, and the second limiting component 22 are each provided with at least two corresponding components that cooperate to form at least two limiting structures. These at least two limiting structures are arranged side-by-side along the second direction. Therefore, each limiting structure can be dedicated to latching and mounting one display screen 200, allowing one transport rack 100 to simultaneously load at least two display screens 200. This enhances the loading and transport capacity of a single transport rack 100, significantly reducing the number of transport racks 100 required when transporting the same number of display screens 200, thereby lowering transportation costs and reducing the difficulty of storing and managing the transport racks 100.

[0080] It should also be noted that the traditional transport rack 100 has a poor limiting effect on the display screen 200, which can easily cause the display screen 200 to become loose during transportation. If the lamp panel 210 of the display screen 200 is set to face the outside of the transport rack 100, it is very easy for the display screen 200 to collide with external objects, thereby causing damage to the lamp panel 210. Therefore, the display screen 200 can usually only be installed in the transport rack 100 in a specific spatial posture with the lamp panel 210 facing the inside of the transport rack 100. At this time, when external objects hit the back shell of the display screen 200, the lamp panel 210 can be kept safe.

[0081] This application, through the coordinated operation of the first limiting mechanism 20 and the second limiting mechanism 60, can effectively constrain the multiple degrees of freedom of the display screen 200 in the X, Y and Z axes after it is installed in the transport frame 100, ensuring that the display screen 200 is installed firmly and will not loosen. On this basis, the display screen 200 does not need to consider the installation orientation of the lamp panel 210, and can be randomly and flexibly installed in the transport frame 100, greatly reducing the installation difficulty and improving the installation efficiency.

[0082] Furthermore, based on any of the above embodiments, the carrier plate assembly 10 also includes a plurality of support legs 13, which are distributedly installed on the bottom surface of the carrier plate 11. For example, four support legs 13 are provided, which are respectively installed at the four top corners of the bottom surface of the carrier plate 11 to provide stable support when the transport frame 100 is placed on the ground. At the same time, they can support the carrier surface at a safe position at a certain height above the ground, so as to avoid dust, sewage and other stains on the ground from splashing and contaminating the display screen 200 if the distance from the ground is too small, thus affecting the hygiene of the display screen 200.

[0083] For example, in maritime or air transport scenarios, to improve transportation efficiency, it is common practice to stack as many transport racks 100 as possible within a single container, thereby transporting a larger number of displays 200 and reducing transportation costs. Therefore, to enable vertical stacking of the transport racks 100, in one embodiment, the support leg 13 is provided with an inclined surface 131, and both the first side railing 30 and the second side railing 40 include inclined beams 30c. The inclined beams 30c are adapted to the inclination direction of the inclined surface 131, allowing the inclined surface 131 of one transport rack 100 to be wedge-fitted with the inclined beam 30c of another transport rack 100, thus enabling the two transport racks 100 to be stacked vertically.

[0084] The wedge-tight assembly structure using inclined plane 131 and inclined beam 30c can be adapted to the stacking of two transport frames 100. Compared with the horizontal stacking structure, the wedge-tight assembly structure has a better limiting effect and can more effectively constrain the relative motion freedom of the two stacked transport frames 100, thereby improving the stability and reliability of the stack.

[0085] Specifically, in this application, all four support legs 13 are provided with inclined surfaces 131. The inclined surfaces 131 of the two support legs 13 located on one side of the length of the support plate 11 are inclined towards the outside of the transport frame 100. The inclined surfaces 131 of the other two support legs 13 located on the other side of the length of the support plate 11 are inclined towards the outside of the transport frame 100, and their inclination direction is different from that of the inclined surfaces 131 on the aforementioned two support legs 13. Correspondingly, the first side railing 30 and the second side railing 40 are each provided with two inclined beams 30c, and the inclination direction of the inclined beams 30c is designed to match their respective inclined surfaces 131. Through the four sets of wedge-tight assembly structures, the stability and reliability of the two transport frames 100 stacked vertically can be greatly improved.

[0086] To facilitate the lifting and stacking of one transport rack 100 onto another transport rack 100, in one embodiment, the carrier plate assembly 10 further includes a forklift positioning plate 14, which is disposed on the bottom surface of the carrier plate 11. The first side railing 30 and the second side railing 40 are spaced apart along a first direction and cooperate to form a clearance opening 30d. When the two transport racks 100 are stacked and assembled, the clearance opening 30d is used to accommodate the forklift positioning plate 14.

[0087] The forklift positioning plate 14 is designed for easy assembly with the forklift's forks, enabling the forklift to lift and stack the transport rack 100. Since the forklift positioning plate 14 is mounted on the bottom surface of the support plate 11 and protrudes forward, a clearance opening 30d is formed between the first side panel and the second side railing 40. This allows the forklift positioning plate 14 of the stacked transport rack 100 to fit precisely into the clearance opening 30d, avoiding interference with the first side railing 30 and / or the second side railing 40. This is a novel structural design feature that distinguishes this application from conventional transport racks 100 with top plate assemblies.

[0088] In addition to the above, this application also proposes a display screen transport device, which includes at least one display screen 200 and at least one transport frame 100 as described in any of the above embodiments, wherein at least one display screen 200 is installed in the transport frame 100 and constitutes a display screen transport module.

[0089] When there are at least two display transport modules, the at least two display transport modules are stacked one on top of the other.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
