Description

Technical Field

[0001] This invention relates to the field of light box technology, and in particular to a portable display light box. Background Technology

[0002] Traditional light boxes consist of a customized advertising cloth (display cloth) with relevant display content, a frame structure, and a built-in light source. The content of the advertising cloth (display cloth) is displayed by illuminating it with the built-in light source, so as to achieve the effect of publicity and display.

[0003] Traditional light boxes typically use a frame structure that is either integrally molded or connected through a fixed installation method. The shape and structure are determined under the initial customization requirements, and the frame structure and overall size of the light box will not be modified later. They are generally used in scenarios that require long-term display.

[0004] However, for applications such as seasonal product exhibitions that only require short-term display needs, obtaining traditional display light boxes through customization incurs certain purchase costs. Furthermore, the light boxes need to be destroyed after each exhibition, resulting in a waste of resources. If the exhibitors choose to take them back, it will increase travel inconvenience. These issues need improvement. Summary of the Invention

[0005] To improve the portability of the lightbox, this application provides a portable display lightbox.

[0006] The portable display lightbox provided in this application adopts the following technical solution:

[0007] A portable display lightbox includes a display fabric and two symmetrically arranged light-blocking plate assemblies.

[0008] One end of each of the two light-blocking plate assemblies is detachably connected with a side cover; the other end of each of the two light-blocking plate assemblies is provided with a storage shell for storing the fabric and the light-blocking plate assembly.

[0009] When the fabric is unfolded, one end of the fabric is detachably connected to the storage housing, and the other end is detachably connected to the side cover.

[0010] The storage housing is equipped with a display light source for illuminating the display fabric;

[0011] When the fabric is unfurled and rolled up, the side cover and the storage housing form a cover fit.

[0012] By adopting the above technical solution, in actual use, both light-blocking plate components and the display cloth can be stored in the storage housing, and the side cover can be placed on the storage housing. Thus, only the storage housing needs to be carried to achieve the function of transferring the entire lightbox. In addition, the display result can be modified by changing different display cloths to adapt to the display of various products. At the same time, by changing light-blocking plate components of different lengths, frame structures with different display areas can be formed to adapt to different display scenarios. Furthermore, the assembly process of the entire lightbox is convenient and quick.

[0013] Preferably, the light-blocking plate assembly includes a plurality of light-blocking plates connected in sequence, and the connection between any of the light-blocking plates is a folding, flipping, turning, or detachable connection method.

[0014] By adopting the above technical solution, multiple light-blocking plates connected in sequence are set up to form a frame structure with different display areas according to the usage requirements. At the same time, the light-blocking plates can be unfolded and formed by folding, flipping, turning or detachable connection.

[0015] Preferably, the light-blocking plate connected to the storage housing is connected to the storage housing by hinge or by connecting a flexible medium.

[0016] By adopting the above technical solution, in actual use, there is no need to disassemble the light-blocking plate. It can be directly stored in the storage housing by rotating it, which is convenient and quick.

[0017] Preferably, the light-blocking plate connected to the side cover is adjustablely connected to the side cover along the length of the light-blocking plate.

[0018] By adopting the above technical solution, the light-blocking plate connected to the side cover is adjustablely connected to the side cover along the length of the light-blocking plate, thereby realizing the fine adjustment of the position between the side cover and the light-blocking plate, and indirectly adjusting the unfolded length of the fabric, which can then be used for tensioning the fabric after it has softened in the later stages of unfolding.

[0019] Preferably, the light-blocking plate connected to the side cover is connected to the side cover by adhesive or magnetic attraction.

[0020] By adopting the above technical solution, the light-blocking plate and the side cover can be detachably connected by adhesive or magnetic attraction, and the connection method can realize the function of fine position adjustment. This adjustment method is convenient and quick.

[0021] Preferably, the two ends of the fabric along its length are connected to the storage housing and the side cover by adhesive bonding, respectively.

[0022] By adopting the above technical solution, in actual use, users can directly fix the two ends of the fabric to the storage shell and side cover by adhesive. This connection method is simple and convenient.

[0023] Preferably, both ends of the fabric along its length are provided with snap-fit ​​grooves, the length direction of the snap-fit ​​grooves being perpendicular to the length direction of the fabric. The storage housing is provided with a snap-fit ​​block that engages with the snap-fit ​​groove at one end of the fabric and is fixed in place. The side cover is provided with a snap-fit ​​block that engages with the snap-fit ​​groove at the other end of the fabric.

[0024] By adopting the above technical solution, in actual use, the snap-fit ​​block inside the housing forms a snap-fit ​​with the snap-fit ​​groove to fix one end of the fabric. This fixing method is easy to disassemble. The snap-fit ​​block on the side cover is used to engage with the snap-fit ​​groove at the other end of the fabric to fix the other end of the fabric. On the other hand, the snap-fit ​​method makes fixing convenient and disassembly convenient.

[0025] Preferably, the two ends of the buckle block in the length direction are formed with insertion grooves, the storage housing is provided with an insertion groove that fits into the side cover, and the storage housing is provided with elastic pin assemblies at both ends of the insertion groove in the length direction that fit into the two insertion grooves.

[0026] By adopting the above technical solution, when actually carrying out storage operations, the user places the side cover in the embedded groove to form a cover fit. At the same time, the two elastic pin components are used to realize the insertion and positioning between the side cover and the two insertion slots on the buckle block, thereby finally achieving the fixation of the side cover, which is convenient and quick.

[0027] Preferably, the storage housing has a snap-fit ​​edge on the other side of the elastic pin assembly, and the side cover has a snap-fit ​​edge that engages with the snap-fit ​​edge.

[0028] By adopting the above technical solution, in actual use, before using the elastic pin assembly to insert and fix the side cover, the user can insert the snap-fit ​​edge on the side cover into the snap-fit ​​edge in the storage shell, thereby achieving the limiting and fixing of the side cover relative to the other side of the elastic pin assembly. This fixing method can improve the fixing effect of the side cover on the storage shell.

[0029] Preferably, the storage housing includes a three-panel body structure and a side panel body structure. The two ends of the three-panel body structure in the length direction are open. There are two side panel body structures located at the openings of the three-panel body structure and detachably connected to the three-panel body structure. Each of the side panel body structures is provided with a limiting groove that forms a limiting fit with the snap-fit ​​edge.

[0030] By adopting the above technical solution, during the actual assembly of the storage shell, the three-panel structure can be directly integrally molded to form a "U"-shaped structure. For the open ends of the three-panel structure, two side panel structures are then connected to the three-panel structure in a detachable manner. During the detachable connection process, the snap-fit ​​edge on the storage structure is used to form a limiting fit with the limiting groove on the side panel structure, thereby facilitating the assembly of the two side panel structures by the staff.

[0031] Preferably, the light-blocking plate assembly has a reflective layer on the side near the fabric.

[0032] By adopting the above technical solution, a light-blocking plate assembly is used.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. A display frame can be formed by using a storage shell, two light-blocking plate assemblies, and side covers. The display frame can be adjusted using the light-blocking plate assemblies to adapt to different display area requirements. At the same time, during assembly and disassembly, the two light-blocking plate assemblies, the display cloth, and the side covers can all be directly stored in the storage shell to achieve the purpose of portable transportation. That is, the light box has the characteristics of easy assembly and disassembly and portable transportation, and users do not need to customize or purchase light boxes every time, thus avoiding cost waste.

[0035] 2. By using the connection method between multiple light-blocking plates, and by adjusting the connection of the light-blocking plates to the side cover along the length of the light-blocking plates, the entire light box structure has the function of long-distance adjustment and short-distance fine adjustment, so as to adapt to different lengths of display cloth and to tension the display cloth.

[0047] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0048] This application discloses a portable display lightbox.

[0049] Example 1

[0050] Reference Figure 1 and Figure 2The portable display lightbox includes a storage housing 1, a display cloth 2, a side cover 3, and two symmetrically arranged light-blocking plate assemblies 4. The storage housing 1 is located at one end of the two light-blocking plate assemblies 4, and the side cover 3 is detachably connected to the other end of the light-blocking plate assemblies 4. The display cloth 2 is rolled up and placed inside the storage housing 1, and one end of the display cloth 2 is detachably connected to the storage housing 1, and the other end is detachably connected to the side cover 3. The storage housing 1 is also provided with a display light source 5 for illuminating the display cloth 2.

[0051] Reference Figure 1 and Figure 2 In actual use, after the storage shell 1, side cover 3 and two light-blocking plate assemblies 4 are assembled, a rectangular frame is formed. In other embodiments, the lengths of the storage shell 1, side cover 3 and light-blocking plate assemblies 4 can be adjusted as needed to form different quadrilateral frame structures or triangular frame structures. Then, the display cloth 2 is unfolded from one end of the storage shell 1 to one end of the side cover 3. The wall is used to close the space on the side of the rectangular frame away from the display cloth 2. Finally, the display light source 5 is concentrated in the closed space to illuminate the display cloth 2, so as to achieve the final formation of the light box.

[0052] Reference Figure 2 and Figure 3 The housing 1 includes a three-panel body structure 11 and a side panel body structure 12. The two ends of the three-panel body structure 11 in the length direction are open. The three-panel body structure 11 includes a first horizontal vertical part 111, a vertical part 112 and a second horizontal vertical part 113 that are perpendicular to each other in sequence. That is, the cross section of the three-panel body structure 11 perpendicular to its length direction is a U-shaped structure. A snap-fit ​​block 1121 with a T-shaped cross section is integrally formed on the vertical part 112. A snap-fit ​​edge 1131 that is perpendicular to the second horizontal vertical part 113 is integrally formed on the second horizontal vertical part 113. The display light source 5 is installed on the vertical part 112.

[0053] Reference Figure 3 and Figure 4 Two side panel structures 12 are provided and located at the opening of the three-panel structure 11. Both side panel structures 12 are fixed to the first horizontal vertical part 111, the vertical part 112 and the second horizontal vertical part 113 of the three-panel structure 11 by screws, forming a detachable connection with the storage shell 1. The bottom of each side panel structure 12 is provided with a limiting groove 121 that forms a limiting fit with the snap-fit ​​edge 1131. The side of each side panel structure 12 near the vertical part 112 is provided with a clearance notch 122 for avoiding the snap-fit ​​block 1121. In actual installation, the limiting fit between the snap-fit ​​edge 1131 and the limiting groove 121 can be used to facilitate the positioning and installation of the side panel structure 12.

[0054] Reference Figure 3 and Figure 5 Both ends of the fabric 2 along its length are fixed with fasteners 21. Each of the two fasteners 21 has a snap-fit ​​groove 211 on one side facing away from each other. The length direction of the snap-fit ​​groove 211 is perpendicular to the length direction of the fabric 2. The snap-fit ​​groove 211 on the fastener 21 at one end of the fabric 2 along its length forms an insertion fit with the snap-fit ​​block 1121 on the vertical part 112. That is, before actually assembling the two side panel structures 12, the fastener 21 of the fabric 2 is inserted into the snap-fit ​​block 1121 through the opening at any end of the three panel structure 11, thus completing the fixed installation of that end of the fabric 2 on the storage housing 1.

[0055] Reference Figure 3 and Figure 5 A fastening block 31 is provided on one side of the long side of the cover 3 along its length direction. The fastening block 31 and the snap-fit ​​groove 211 on the edge fastener 21 at the other end of the fabric 2 form a fastening engagement. The cross-section of the fastening block 31 is L-shaped. When in use, the user only needs to hold the edge fastener 21 at the other end of the fabric 2 and fasten the snap-fit ​​groove 211 of the edge fastener 21 onto the fastening block 31 to complete the detachable connection between that end of the fabric 2 and the cover 3.

[0056] Reference Figure 3 and Figure 5 The two ends of the buckle block 31 in the length direction are formed with insertion grooves 311. Correspondingly, the housing 1 is formed with an insertion groove 114 on the upper side of its opening to fit with the side cover 3. The two side panel structures 12 are provided with elastic pin assemblies 6 on opposite sides to fit with the two insertion grooves 114. The two elastic pin assemblies 6 are located on both sides of the insertion groove 114 in the length direction.

[0057] Reference Figure 3 and Figure 5 On the other side of the long side of the cover 3, a snap-fit ​​edge 32 is provided along its length direction. The snap-fit ​​edge 32 and the snap-fit ​​edge 1131 on the second horizontal vertical part 113 form a snap-fit ​​engagement, that is, the snap-fit ​​edge 32 abuts against the side of the overlapping edge near the vertical part 112.

[0058] Reference Figure 3 and Figure 6 Since the structures of the two elastic pin assemblies 6 and their installation methods on the corresponding side panel structure 12 are the same, we will now take one of them as an example for explanation.

[0059] Reference Figure 3 and Figure 6The elastic pin assembly 6 includes a pin 61, a compression spring 62, and a drive block 63. A mounting groove 123 is provided on the side panel structure 12 near the embedding groove 114, and a waist-shaped drive groove 124 is provided on the side panel structure 12 perpendicular to the mounting groove 123. The length direction of the waist-shaped drive groove 124 is parallel to the width direction of the spread fabric 2. The compression spring 62 and the pin 61 are located in the mounting groove 123 and are arranged in abutment with each other. The compression spring 62 is located on the side of the pin 61 away from the embedding groove 114. A positioning groove 611 is provided on the pin 61. The drive block 63 is located in the waist-shaped drive groove 124 and passes through the positioning groove 611 of the pin 61. It is fixed to the pin 61 by a nut.

[0060] Reference Figure 3 and Figure 6 When actually installing the side cover 3, simply place the snap-fit ​​edge 32 on the long side of the side cover 3 against the snap-fit ​​edge 1131 near the vertical part 112, then place the snap-fit ​​block 31 of the side cover 3 into the mounting groove 114, and then manually drive the two drive blocks 63 so that the two drive blocks 63 move in the two waist-shaped drive grooves 124 in a direction away from each other, thereby driving the two insertion pins 61 to move in a direction away from each other, so that the insertion grooves 311 at both ends of the length direction of the snap-fit ​​block 31 are located in the mounting groove 114. Then, the user only needs to release the two drive blocks 63, and under the elastic force of the two compression springs 62, drive the two insertion pins 61 to insert and fix the insertion pins 61 at both ends of the snap-fit, thereby realizing the installation and fixation of the side cover 3.

[0061] Reference Figure 1 and Figure 2 Since the structure of any light-blocking plate assembly 4 and the installation method between it and the corresponding side panel structure 12 and side cover 3 are the same, we will now take one of the light-blocking plate assemblies 4 as an example for explanation.

[0062] Reference Figure 1 and Figure 2 The light-blocking plate assembly 4 includes multiple light-blocking plates connected in sequence. Adjacent light-blocking plates are connected by folding, flipping, turning, or detachable methods. In this embodiment, two light-blocking plates are provided: a first light-blocking plate 41 and a second light-blocking plate 42. A rotating rivet is used between the first light-blocking plate 41 and the second light-blocking plate 42 to achieve rotational folding and overlapping for storage. In other embodiments, a hinged joint can be used between the first light-blocking plate 41 and the second light-blocking plate 42 to achieve rotational overlap. In this embodiment, the rotation axis is perpendicular to the rotation axis in the rotating rivet connection method.

[0063] In other embodiments, detachable bolts and nuts may be provided at the connection between the first light-blocking plate 41 and the second light-blocking plate 42 to achieve a detachable connection between the first light-blocking plate 41 and the second light-blocking plate 42.

[0064] Reference Figure 1 and Figure 2 In addition, the first light-blocking plate 41 and the second light-blocking plate 42 are both coated with a reflective layer 7 on the side near the display fabric to improve the overall brightness. In other embodiments, a reflector can also be provided on the side of the side cover facing the storage housing to fully reflect the light source. Optimally, in other embodiments, the angle of the reflector can also be adjusted so that the reflected light source fully illuminates the display fabric.

[0065] Reference Figure 3 A first rotating hinge 8 is provided on the side panel body structure 12. One side of the first rotating hinge 8 is fixed to the side panel body structure 12 by screws, and the other side is connected to the first light-blocking plate 41 by screws. In fact, when storing, the user only needs to rotate the first light-blocking plate 41 to store the first light-blocking plate 41 into the storage housing 1.

[0066] Reference Figure 7 A second rotating hinge 9 is provided at the end of the side cover 3 along its length. One side of the second rotating hinge 9 is fixedly connected to the side cover 3 by screws, and the other side of the second rotating hinge 9 is provided with a connecting area 91. The second light-blocking plate 42 is provided with a connecting part 421 for adhesive bonding to form an adhesive fit. Specifically, the connecting part 421 and the connecting area 91 can be connected by Velcro, or the connecting part 421 can be a magnetic piece, and the connecting area 91 can be a metal area, thus the connecting part 421 and the connecting area 91 can also be connected by magnetic attraction. The rotation angle of the first rotating hinge 8 and the second rotating hinge 9 is set to 0° to 90°, thereby ensuring the stability of the entire frame structure.

[0067] The implementation principle of a portable display lightbox in this application embodiment is as follows:

[0068] During the actual exhibition, the pins securing the two elastic components are released, and then the side cover 3 is removed from the storage housing 1. Next, the two light-blocking plate assemblies 4 are removed from the storage housing 1 by rotating them outwards. The first light-blocking plate 41 and the second light-blocking plate 42 of the two light-blocking plate assemblies 4 are unfolded by rotating them separately. Then, the second light-blocking plate 42 of the two light-blocking plate assemblies 4 is fixed to the second rotating hinge 9 on the side cover 3 by adhesive, forming a rectangular frame structure. Finally, the user only needs to pull one end of the display cloth 2 to the latch block 31 on the side cover 3, turn on the display light source 5, and fix the side of the entire light box structure away from the display cloth 2 to the wall by the hanging lugs to realize the display function of the light box.

[0069] Example 2

[0070] Reference Figure 8 The difference between this embodiment and Embodiment 1 is that...

[0071] A flexible medium 10 is provided between the first light-blocking plate 41 and the side panel structure 12. That is, the first light-blocking plate 41 is connected to the storage housing 1 through the connecting flexible medium 10. In this embodiment, the flexible medium 10 is set as a connecting piece made of fabric. In other embodiments, the flexible medium 10 can also be set as a connecting piece made of soft rubber. In actual storage, the user only needs to rotate the two first light-blocking plates 41 to store them into the storage housing 1.

[0072] Example 3

[0073] Reference Figure 9 The difference between this embodiment and embodiments 1 and 2 is that...

[0074] The two ends of the fabric 2 along its length are respectively connected to the vertical part 112 of the storage housing 1 and the fastener 31 of the side cover 3 by adhesive bonding. This achieves the connection and fixation of the fabric 2 between the storage housing 1 and the side cover 3.

[0075] Example 4

[0076] Reference Figure 10 The difference between this embodiment and Embodiment 1 is that...

[0077] The side cover 3 is provided with a guard edge 33, which is L-shaped and faces the direction of the spread fabric 2. That is, it covers the edge fastener 21 at one end of the spread fabric 2 and plays a protective and shielding role in the connection between the edge fastener 21 and the fastener block 31.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
