Description

Technical Field

[0001] This application relates to the field of advertising technology, and in particular to a lightbox made of light cloth and a method for splicing light cloth. Background Technology

[0002] A backlit lightbox is an advertising display tool, also known as a backlit lightbox. It typically consists of a box with a transparent or semi-transparent material, an internal lighting system, and a lightbox fabric laid on the box. Lightbox fabrics are commonly used in commercial advertising, indoor displays, and promotional events. Using lightbox fabric offers advantages such as strong color fastness, suitability for color printing, good light transmittance, self-cleaning properties, strong typhoon resistance, and low price.

[0003] Currently, some commercial stores have very long light boxes, reaching tens of meters or even hundreds of meters. Such long light boxes need to be customized from manufacturers, and the matching film is also difficult to match with the light box, which also increases the difficulty of producing the surface image on the light box, thus increasing the production cost of the product.

[0004] In addition, most light curtains and light boxes are installed at heights, and the weight of excessively long light curtains is also increased. Using a lift truck to install them section by section makes the installation work inconvenient. At the same time, the light curtain is the outermost surface of the light box, and it needs better protection during installation, all of which increase the difficulty of construction. Summary of the Invention

[0005] The purpose of this application is to provide a more convenient method for installing light boxes and light fabrics, as well as for splicing light boxes.

[0006] Firstly, the light box provided in this application adopts the following technical solution: A light box with light cloth includes a box body, light cloth, and light strip placed inside the box body. The light cloth is fixed to the box body. The box body includes a fixing frame and multiple fixing members that can be set on the fixing frame. The fixing members are used to fix the light cloth. The light cloth includes multiple cloth segments, which are sequentially spliced ​​to form the light cloth. The fixing members are arranged in one-to-one correspondence with the cloth segments, and the ends of adjacent cloth segments can extend into the corresponding fixing members.

[0007] By adopting the above technical solution, multiple fabric segments are spliced ​​together in sequence to form the lamp cloth, which reduces the cost of producing large-format lamp cloth. When installing the lamp cloth, the fabric segments are fixed to the box in sequence, and the ends of adjacent fabric segments extend into the fasteners to complete the splicing, making the installation more convenient.

[0008] Optionally, the fastener includes a fixing plate, fixing bolts, and clamps disposed on both sides of the fixing plate, wherein the fixing plate and the clamps are provided with fixing holes that match the fixing bolts.

[0009] By adopting the above technical solution, the end of the fabric segment along the length direction is inserted between two clamps, and then the fixing hole is screwed in. During the screwing process, the fabric segment is punctured to complete the splicing between adjacent fabric segments. The connection is stable and easy to install.

[0010] Optionally, both the fixing plate and the clamping plate are made of a light-diffusing plate.

[0011] By adopting the above technical solution, since both the fixing plate and the clamping plate are made of light-diffusing plates, when light shines on the fixing plate and the clamping plate, the fixing plate and the clamping plate can diffuse the light from the point source to a wider range of angles, so that the light can illuminate the target area more fully, that is, shine on the light cloth, which is beneficial to improving the display effect of the light cloth.

[0012] Optionally, the clamping plate is offset from the fixing plate in a direction away from the box body, and the side of the adjacent clamping plate away from the fixing plate is inclined.

[0013] By adopting the above technical solution, the clamping plate is kept at a certain distance from the cabinet. When the light strip is in working condition, the obstruction of light by the clamping plate can be reduced. The inclined setting of the side of the clamping plate away from the fixing plate also leaves more space, so that the light can illuminate the clamping plate and the bent part after the fabric segment extends into the fixing component. This reduces the possibility that the splicing part between adjacent fabric segments has no lighting effect or the lighting effect is weaker than other parts. The light distribution is more uniform, which is conducive to improving the display effect of the light cloth.

[0014] Optionally, the thickness of the fixing plate is at most twice the thickness of the fabric segment.

[0015] The distance between the two clamping plates is directly related to the thickness of the fixing plate. By adopting the above technical solution, the corresponding ends of adjacent fabric segments are inserted between the two clamping plates. At this time, the sidewalls of the fabric segments and the sidewalls of the clamping plates are tightly abutted together, making the connection between the fabric segments and the clamping plates more stable and reliable. This can better resist the possibility of shaking caused by external factors interfering with the lamp cloth, and improve the stability of the spliced ​​parts of adjacent fabric segments.

[0016] Optionally, the fixing frame includes a frame platform and a connector for fixing the frame platform. The connector is detachably connected to the frame platform. The connector includes a first connecting plate and a second connecting plate. The first connecting plate is inserted into the second connecting plate. A fixing shaft is connected to the first connecting plate, and a matching insertion slot for the fixing shaft is provided on the second connecting plate.

[0017] By adopting the above technical solution, when installing the cabinet, the frame plate is first fixed at the installation point, and then the insertion slot is aligned with the fixing shaft to insert the stand onto the frame plate. When the cabinet is damaged, the frame plate or stand can be repaired accordingly. Compared with the integrated light box, its disassembly and assembly are simpler and more convenient, and the subsequent maintenance cost is also lower.

[0018] Optionally, a connecting strip extends from the fabric segment, the connecting strip has mounting holes, and a mounting shaft is mounted on the frame, the connecting strip being able to be sleeved on the mounting shaft.

[0019] By adopting the above technical solution, before splicing adjacent fabric sections, the fabric sections are first aligned with the frame on both sides along the width direction. Then, the connecting straps are put on the mounting shaft. The fabric sections are tightened by the constraint of the mounting shaft, which allows relevant personnel to better splice the light cloth and also improves the viewing experience of tourists when reading the content on the light cloth.

[0020] Optionally, the connector further includes a support base, which is detachably connected to the first connecting plate.

[0021] By adopting the above technical solution, the support base is fixed to the wall where the light box needs to be installed by bolts. The support base provides an installation point for the frame plate, and the side wall of the angle steel abuts against and is further connected to the support base and the frame plate respectively, making the connection between the light box and the wall more stable and reliable.

[0022] Secondly, the method for splicing light curtains provided in this application includes the following steps: S1. Transport multiple fabric sections to the installation location; S2. Arrange multiple fabric segments sequentially along their length and fix both ends of the fabric segments along their width to the frame. S3. Measure the length of the fabric section and locate the installation point of the fastener based on the measurement data; S4. Insert the ends of adjacent fabric segments along the length direction into the space between the corresponding clamping plate and the fixing plate, and screw in the fixing bolts to secure them.

[0023] By adopting the above technical solution, when installing the lamp cloth, the cloth segments are arranged and fixed on the box in sequence, and then the ends of the cloth segments are inserted between the clamping plate and the fixing plate and tightened with fixing bolts, making the installation more convenient.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The lamp cloth in this application is formed by splicing multiple cloth segments in sequence, which reduces the cost of producing large-format lamp cloth. When installing the lamp cloth, the cloth segments are fixed to the box in sequence, and the ends of adjacent cloth segments extend into the fasteners to complete the splicing, making the installation more convenient.

[0025] 2. In this application, adjacent fabric segments are fixed by fasteners so that they can be spliced ​​together. The clamping plate and the housing are kept at a certain distance. When the light strip is in working condition, the obstruction of light by the clamping plate can be reduced. The inclined setting of the side of the clamping plate away from the fixing plate also leaves more space, so that the light can illuminate the bending part of the clamping plate and the fabric segment after it extends into the fastener. This reduces the possibility that the splicing part between adjacent fabric segments has no lighting effect or a weaker lighting effect compared to other parts. The light distribution is more uniform, which is conducive to improving the display effect of the light strip.

[0026] 3. The clamps in this application are located at both ends of the fixing plate. The corresponding ends of adjacent fabric segments that are close to each other are inserted between the two clamps. At this time, the side wall of the fabric segment and the side wall of the clamp are tightly abutted together. The connection between the fabric segment and the clamp is more stable and reliable, and can better resist the possibility of shaking caused by external factors interfering with the lamp cloth, thereby improving the stability of the splicing part of adjacent fabric segments.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0033] A type of lightbox made of light cloth, as shown in the reference Figure 1 and Figure 2 The device includes a housing 1, a light strip 3 and a light cloth 2 placed inside the housing 1. The outer wall of the housing 1 is connected to a connector 112 and fixed to the corresponding wall surface by the connector 112. The light cloth 2 is arranged opposite to the connector 112 and fixed on the side of the housing 1 with an opening 13.

[0034] Reference Figure 1 and Figure 2 The housing 1 includes a fixing frame 11 and multiple fixing members 12 that can be set on the fixing frame 11. The fixing members 12 are arranged sequentially along the length of the lamp cloth 2 and are used to fix the lamp cloth 2. Specifically, the lamp cloth 2 includes multiple cloth segments 21, which are spliced ​​together sequentially to form the lamp cloth 2. The fixing members 12 are correspondingly set with the cloth segments 21 and are located at the splicing points between adjacent cloth segments 21. The ends of adjacent cloth segments 21 can extend into the corresponding fixing members 12.

[0035] Reference Figure 1 and Figure 2 The fixing frame 11 includes a frame 111 and a connector 112 for fixing the frame 11. The frame 111 and the connector 112 are detachably connected. The connector 112 includes a first connecting plate 1121 and a second connecting plate 1122. The first connecting plate 1121 and the second connecting plate 1122 are inserted into each other. A fixing shaft 113 is passed through the first connecting plate 1121. There are two fixing shafts 113. The two fixing shafts 113 are symmetrically arranged along the height direction of the clamping plate 123. The second connecting plate 1122 has a insertion groove 1123 that matches the fixing shaft 113. The insertion groove 1123 is specifically divided into a guide groove 11231 and a fixing groove 11232. The guide groove 11231 and the fixing groove 11232 are connected. The mounting shaft 114 enters from the guide groove 11231 into the fixing groove 11232 and is finally fixed by the groove wall of the fixing groove 11232.

[0036] Reference Figure 2 The guide groove 11231 has a wider opening than the fixing groove 11232. One side of the guide groove 11231 is inclined to reduce the obstruction of the guide groove 11231 wall when the first connecting plate 1121 and the second connecting plate 1122 are inserted. The fixing groove 11232 is circular, and the opening diameter of the fixing groove 11232 is slightly larger than the outer diameter of the fixing shaft 113 to facilitate installation. Specifically, in this embodiment, there are multiple fixing shafts 113. The outer diameter of the fixing shaft 113 is 8mm and the length is 65mm. The opening diameter of the fixing groove 11232 is 10mm. The outer end of the fixing shaft 113 is equipped with a retaining ring. Adjacent fixing shafts 113 are fixed by retaining rings. When installing the fixing bracket 11, the insertion groove 1123 is aligned with the fixing shaft 113 and the second connecting plate 1122 is inserted into the first connecting plate 1121 to complete the connection.

[0037] Reference Figure 1 and Figure 2 The connector 112 also includes a support base 1124. Multiple support bases 1124 are arranged in pairs along the length of the first connecting plate 1121 and are detachably connected to it. The two support bases 1124 in each pair are positioned opposite each other along the height of the first connecting plate 1121. Specifically, each support base 1124 includes a mounting plate 11241, a support beam 11242, and an angle steel 11243. The mounting plate 11241 and the support beam... The components are integrally formed by welding, while the angle steel 11243 is set on the side wall of the support beam 11242 and is detachably connected to the support beam 11242 and the first connecting plate 1121 by bolts. The mounting plate 11241 has multiple mounting holes 11244 for screws to be inserted. When installing the connector 112, the mounting plate 11241 is brought into contact with the mounting surface of the bracket 111 to be installed and screws are inserted to provide a connection point. Specifically, expansion bolts can be used to screw into the base surface, making installation simple.

[0038] Reference Figure 1 and Figure 2 The frame 111 includes a base plate 1111 and baffles 1112 vertically disposed at both ends of the base plate 1111. The base plate 1111 is fixed to the second connecting plate 1122 by bolts. In order to improve the stability of the connection between the base plate 1111 and the second connecting plate 1122, structural adhesive is also added between the base plate 1111 and the second connecting plate 1122. The baffles 1112 are fastened to the base plate 1111 by screws. Furthermore, in order to improve the overall strength of the frame 111, a reinforcing plate 1113 is also provided between the baffles 1112 and the base plate 1111. The reinforcing plate 1113 is inclined and its two ends are respectively connected to the base plate 1111 and the baffles 1112.

[0039] Reference Figure 1 and Figure 2 A light panel 115 is connected to the substrate 1111. The light panel 115 is fastened to the substrate 1111 with screws. The two ends of the light panel 115 are bent to make the whole structure U-shaped. Multiple light strips 3 are evenly arranged on the unbent part of the light panel 115. The light is scattered and diffused after passing through the bent part, making the light softer. As a preferred embodiment of this application, the light strip 3 in this embodiment is preferably an LED light, which is easy to install and energy efficient.

[0040] Reference Figure 1 and Figure 2The fabric segment 21 has connecting strips 22 extending from both ends along its width direction. The thickness of the connecting strips 22 gradually increases in the direction away from the fabric segment 21. A limiting hole 221 is provided on the far end of the connecting strip 22, and a mounting shaft 114 is correspondingly installed on the substrate 1111. The connecting strip 22 can be sleeved on the mounting shaft 114 through the limiting hole 221. The connection between the connecting strip 22 and the mounting shaft 114 makes the fabric segment 21 taut, improves the display effect of the lamp cloth 2, and facilitates the splicing between adjacent fabric segments 21.

[0041] Reference Figure 1 and Figure 2 To better secure the light panel 115 and the fabric section 21, a fixing plate 116 is connected to the side of the baffle 1112 away from the substrate 1111. A connecting strap 22 is located between the fixing plate 116 and the baffle 1112. The end of the light panel 115 is further bent so that the end is located between the fixing plate 116 and the baffle 1112, and then screws are screwed in to secure it. The screws pass through the fixing plate 116, the connecting strap 22, and the light panel 115 in sequence. Furthermore, one end of the fixing plate 116 extends away from the substrate 1111 and is continuously bent to form a V-shaped structure. The bent part is farther from the center of the substrate 1111 than the baffle 1112, thereby preventing rainwater from dripping onto the light fabric 2 and protecting the light fabric 2.

[0042] Reference Figure 3 and Figure 4 The fixing member 12 includes a fixing plate 121, fixing bolts 122, and clamping plates 123 disposed on both sides of the fixing plate 121. As a preferred embodiment of this application, the fixing plate 121 is partially bent to form an L-shape, and the bent end is screwed into a bolt for detachable connection with the base plate 1111. In other embodiments, the fixing plate 121 can be T-shaped, or it can be integrally molded by a mold, so that the connection between the fixing plate 121 and the base plate 1111 is more reliable and stable.

[0043] Reference Figure 3 and Figure 4 The fixing plate 121 and the clamping plate 123 are both made of light-diffusing plate, while the fixing bolt 122 is made of acrylic material. When light shines on the fixing plate 121, the clamping plate 123 and the fixing bolt 122, it can be effectively refracted and scattered without producing shadows. Furthermore, a special color film is applied to the light cloth 2 to enhance the rendering of the cultural propaganda content on the light cloth 2.

[0044] Reference Figure 3 and Figure 4Both the fixing plate 121 and the clamping plate 123 are provided with fixing holes 124 that match the fixing bolts 122. The fixing bolts 122 are screwed into the fixing holes 124 to fasten the fixing plate 121 and the clamping plate 123. In order to improve the stability of the clamping plate 123 in fixing the fabric segment 21, the thickness of the clamping plate 123 is much greater than the thickness of the fabric segment 21. Specifically, in this embodiment, the thickness of the fabric segment 21 is 1.25mm and the thickness of the clamping plate 123 is 10mm. The clamping plate 123 is offset from the fixing plate 121 in the direction away from the housing 1, so that the distance between the clamping plate 123 and the light strip 3 is greater, so as to reduce the light obstruction of the thicker clamping plate 123. The side of the adjacent clamping plate 123 away from the fixing plate 121 is inclined. In other words, the clamping plate 123 has a sloping surface, so that the thickness of the clamping plate 123 gradually decreases near the splicing end of the fabric segment 21, further reducing the light obstruction of the clamping plate 123.

[0045] A gap is formed between the two clamps 123 to allow the end of the fabric segment 21 to extend into. When the end of the fabric segment 21 extends into the gap, a fixing bolt 122 is screwed in. The fixing bolt 122 passes through one clamp 123, the fabric segment 21 and the other clamp 123 in sequence, at which point the fabric segment 21 is tightened.

[0046] Reference Figure 4 Since the gap between the two clamping plates 123 is equal in size to the thickness of the fixing plate 121, in order to better secure the fabric segment 21, the thickness of the fixing plate 121 in this application is at most twice the thickness of the fabric segment 21. As a preferred embodiment of this application, the thickness of the fixing plate 121 in this embodiment is twice that of the fabric segment 21. When the fabric segment 21 extends between the two clamping plates 123, the end sidewall of the corresponding fabric segment 21 abuts against the clamping plate 123, resulting in stronger constraint and preventing the possibility of the end of the fabric segment 21 sliding in the gap. Specifically, in this embodiment, the thickness of the fixing plate 121 is 2.5 mm. In other embodiments, the thickness of the fixing plate 121 can also be slightly less than twice the thickness of the fabric segment 21 to compress the end of the fabric segment 21 and make the connection more secure.

[0047] This application also discloses a method for splicing light fabric based on the above-mentioned light fabric and light box, including the following steps: S1. Transport multiple fabric segments 21 to the installation location; S2. Arrange multiple fabric segments 21 sequentially along their length direction, and fix both ends of the fabric segments 21 along their width direction to the frame. S3. Measure the length of the fabric section 21 and locate the installation point of the fastener 12 according to the measurement data; S4. Insert the ends of adjacent fabric segments 21 along the length direction into the space between the corresponding clamping plate 123 and the fixing plate 121, and screw in the fixing bolts 122 to fix them.

[0048] The implementation principle of this application embodiment is as follows: the connecting strap 22 extending from the fabric segment 21 is sleeved on the mounting shaft 114, so that the fabric segment 21 is taut and fixed on the fixing frame 11. The fixing member 12 is fastened to the fixing frame 11 according to the position of the end of the fabric segment 21. Then another fabric segment 21 is fastened to the fixing frame 11.

[0049] Since the clamping plate 123 is offset from the fixing plate 121 in the direction away from the box 1, the distance between the clamping plate 123 and the light strip 3 is relatively far, the clamping plate 123 has a small degree of light blocking, and a gap is formed between the two clamping plates 123. The ends of the two fabric segments 21, i.e. the splicing parts, are inserted into the gap and fixed with fixing bolts 122 to fix them, so that the two adjacent fabric segments 21 are spliced ​​together. Then the above operation is repeated to fix the remaining fabric segments 21. The light cloth 2 is formed in this way, which is convenient to install, reduces the cost of producing large light cloth 2 and the difficulty of installation. The clamp 123 is connected to the fixing frame 11 through the fixing plate 121. Adjacent cloth sections 21 are fixed by the clamp 123, which reduces the degree of light blockage, makes the light distribution more uniform, and does not produce shadows when the light shines on the light cloth 2, resulting in a better display effect of the light cloth 2.

[0050] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
