Description

Technical Field

[0001] This invention relates to the field of advertising light box manufacturing technology, and specifically to an advertising light box. Background Technology

[0002] Electronic light boxes are a type of indoor and outdoor advertising sign suitable for various occasions. They use LEDs as the light source and acrylic, aluminum composite panels, or plastic panels as the faceplate. Compared to other light boxes, they have significant advertising advantages, primarily in their high brightness and effective advertising impact. The advertising effect per unit area is significantly more prominent than other light box products, and the dazzling effect easily attracts attention, truly fulfilling the purpose of advertising. The product market is in a developmental stage, and prices are becoming increasingly affordable, giving it unparalleled industry advantages and making it one of the main advertising products for a considerable period to come.

[0003] In modern production, due to industrial development, the structure of advertising light boxes is designed differently depending on the market. Most existing advertising light boxes are wall-mounted, which can be further divided into fixed content and replaceable content. Fixed wall-mounted light boxes use fixed LEDs to display content, while replaceable wall-mounted light boxes use replaceable translucent advertising cloth in conjunction with LEDs to change content. Current equipment still uses the old method of completely disassembling and assembling the entire light box, replacing the advertising cloth on the ground, and then reinstalling the light box.

[0004] However, in actual use, the existing method of replacing advertising cloth still adopts the old method of complete disassembly and assembly, that is, disassembling the light box as a whole, replacing the advertising cloth on the ground, and then reinstalling the light box. This method is time-consuming and labor-intensive. Frequent disassembly and assembly will cause wear and tear on the connection structure of the light box, which will reduce the service life of the light box. Moreover, the replacement of large advertising cloth is still very troublesome. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing an advertising light box.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0007] This invention provides an advertising lightbox, comprising a lightbox, a first guide rail at the lower end of the lightbox, a first clamping device and a second clamping device slidably fitted within the first guide rail, a second guide rail on the inner side wall of the lightbox, a guide member within the second guide rail, the guide member being fixedly connected to the top end of the second guide rail via an elastic member, the first clamping device and the second clamping device being connected to a motor via ropes, the first clamping device clamping the advertising cloth in cooperation with the second clamping device, and the first clamping device and the second clamping device slidably fitting with the second guide rail.

[0008] Furthermore, the first guide rail includes a guide groove and a limiting groove. The guide groove is slidably engaged with the first clamping device and the second clamping device, and the limiting groove is engaged with the first clamping device and the second clamping device through a sliding slider. By setting the guide groove and the limiting groove, the two clamping devices are limited by the limiting groove, preventing them from falling off the light box. The guide groove allows the two clamping devices to separate, thereby clamping the advertising cloth. When the two clamping devices are separated, the advertising cloth is clamped and arranged, making the cooperation between the advertising cloth and the light box smoother. This makes the disassembly and assembly of the advertising cloth more convenient and quick, effectively improving the efficiency of the disassembly and assembly of the advertising cloth.

[0009] Furthermore, the second guide rail and the slider are in sliding engagement; by setting the engagement between the slider and the second guide rail, when the two clamping devices slide to the second guide rail respectively, the two clamping devices are moved from horizontal to vertical by the rope, thereby realizing the installation of the advertising cloth and effectively improving the installation efficiency of the advertising cloth.

[0010] Furthermore, the first clamping device includes a first guide block, an upper clamping strip, and a lower clamping strip, which cooperate to clamp the advertising cloth. The first guide block has a first groove that mates with the advertising cloth. By setting the structure of the first clamping device, the advertising cloth can be stretched and installed by the first guide block, and the ends of the advertising cloth can be fixed by the two clamping strips, thereby effectively improving the installation efficiency of the advertising cloth. Moreover, the advertising cloth is fixed and stretched by the two clamping devices, so that the advertising cloth can also be disassembled by the two clamping devices, thereby effectively improving the disassembly efficiency of the advertising cloth.

[0011] Furthermore, the lower end of the upper clamping strip is provided with a buckle, and the lower clamping strip is provided with a groove that cooperates with the buckle. By providing the buckle and the groove, when the second clamping device cooperates with the first clamping device, as the second clamping device gradually slides, the two clamping strips begin to fit together vertically. The cooperation of the buckle and the groove makes the upper and lower clamping strips more stable, and the advertising cloth is clamped between the two clamping strips, thereby fixing the top of the advertising cloth and making the installation of the advertising cloth more convenient, effectively improving the installation efficiency of the advertising cloth. When disassembling, the two clamping strips can also be separated by the cooperation of the two clamping devices, thereby realizing the removal of the advertising cloth from the light box, effectively improving the disassembly efficiency of the advertising cloth.

[0012] Furthermore, the second clamping device has two second grooves, which slide in cooperation with the upper clamping strip and the lower clamping strip respectively, and the cross-sections of the two second grooves are close to each other. By setting the second grooves, when the second clamping device is away from the first clamping device, the second clamping device will use the second grooves to bring the two clamping strips close to each other and engage them, thereby realizing the installation of the advertising cloth. When disassembling, it is only necessary to bring the second clamping device close to the first clamping device, which effectively improves the disassembly efficiency of the advertising cloth.

[0013] Furthermore, the second clamping device has a third groove, which engages with the advertising cloth; by providing the third groove, the second clamping device and the advertising cloth are engaged.

[0014] Furthermore, the second clamping device is also provided with a fourth groove, which slides in conjunction with the buckle; by providing the fourth groove, the second clamping device and the first clamping device can be coordinated.

[0015] Furthermore, a stop is provided at one end of both the upper and lower clamping strips, and the outer diameter of the stop is larger than the outer diameter of the upper and lower clamping strips. By providing the stop, the upper and lower clamping strips are prevented from disengaging when they cooperate with the first clamping device, thereby making the advertising cloth more stable.

[0016] Furthermore, a fifth groove is provided near the stop block in the third groove, and the fifth groove cooperates with the stop block; by providing the fifth groove, the second clamping device cooperates with the two clamping bars, thereby preventing the two clamping bars from detaching from the second clamping device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention achieves automatic installation of the advertising cloth by setting a motor to pull two clamping devices. Then, through the cooperation of the first and second clamping devices, the top of the advertising cloth is fixed. Finally, through the cooperation of the guide and elastic components, the advertising cloth can be automatically removed when the motor is de-energized, effectively improving the disassembly efficiency of the advertising cloth.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0030] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0032] This invention provides an advertising light box, with reference to Figure 1-7 The light box 1 includes a first guide rail 2 at its lower end. A first clamping device 3 and a second clamping device 4 are slidably fitted inside the first guide rail 2. A second guide rail 5 is provided on the inner side wall of the light box 1. A guide member 6 is provided inside the second guide rail 5. The guide member 6 is fixedly connected to the top of the second guide rail 5 through an elastic member 7. The first clamping device 3 and the second clamping device 4 are both connected to a motor 9 through a rope 8. The first clamping device 3 clamps the advertising cloth 10 by cooperating with the second clamping device 4. The first clamping device 3 and the second clamping device 4 are slidably fitted with the second guide rail 5.

[0033] The first guide rail 2 includes a guide groove 11 and a limiting groove 12. The guide groove 11 is slidably engaged with the first clamping device 3 and the second clamping device 4. The limiting groove 12 is engaged with the first clamping device 3 and the second clamping device 4 through a sliding slider 13. By setting the guide groove 11 and the limiting groove 12, the two clamping devices are limited by the limiting groove 12, preventing them from falling off the light box 1. The guide groove 11 allows the two clamping devices to separate, thereby clamping the advertising cloth 10. When the two clamping devices are separated, the advertising cloth 10 is clamped and arranged, making the cooperation between the advertising cloth 10 and the light box smoother. This makes the disassembly and assembly of the advertising cloth 10 more convenient and faster, effectively improving the efficiency of the disassembly and assembly of the advertising cloth 10.

[0034] The second guide rail 5 is slidably engaged with the slider 13. By setting the slider 13 to engage with the second guide rail 5, when the two clamping devices slide to the second guide rail 5 respectively, the two clamping devices are moved from horizontal to vertical by the rope 8, thereby realizing the installation of the advertising cloth 10 and effectively improving the installation efficiency of the advertising cloth 10.

[0035] The first clamping device 3 includes a first guide block 14, an upper clamping strip 15, and a lower clamping strip 16. The first guide block 14, the upper clamping strip 15, and the lower clamping strip 16 cooperate to clamp the advertising cloth 10. The first guide block 14 has a first groove 17 that cooperates with the advertising cloth 10. By setting the structure of the first clamping device 3, the advertising cloth 10 can be stretched and installed by the first guide block 14, and the ends of the advertising cloth 10 can be fixed by the two clamping strips, thereby effectively improving the installation efficiency of the advertising cloth 10. Moreover, the advertising cloth 10 can be fixed and stretched by the two clamping devices, so that the advertising cloth 10 can also be disassembled by the two clamping devices, thereby effectively improving the disassembly efficiency of the advertising cloth 10.

[0036] The upper clamping strip 15 has a buckle 18 at its lower end, and the lower clamping strip 16 has a slot 19 that engages with the buckle 18. By setting the buckle 18 and the slot 19, when the second clamping device 4 engages with the first clamping device 3, as the second clamping device 4 gradually slides, the two clamping strips begin to fit together vertically. The engagement of the buckle 18 and the slot 19 makes the engagement of the upper clamping strip 15 and the lower clamping strip 16 more stable, and the advertising cloth 10 is clamped between the two clamping strips, thereby fixing the top of the advertising cloth 10. This makes the installation of the advertising cloth 10 more convenient and effectively improves the installation efficiency of the advertising cloth 10. When disassembling, the two clamping strips can also be separated by the engagement of the two clamping devices, thereby allowing the advertising cloth 10 to detach from the light box 1, effectively improving the disassembly efficiency of the advertising cloth 10.

[0037] The second clamping device 4 has two second grooves 20, which slide and engage with the upper clamping strip 15 and the lower clamping strip 16 respectively. The cross-sections of the two second grooves 20 are close to each other. By setting the second grooves 20, when the second clamping device 4 is away from the first clamping device 3, the second clamping device 4 uses the second grooves 20 to bring the two clamping strips close to each other and engage them, thereby realizing the installation of the advertising cloth 10. When disassembling, it is only necessary to bring the second clamping device 4 close to the first clamping device 3, which effectively improves the disassembly efficiency of the advertising cloth 10.

[0038] The second clamping device 4 has a third groove 21, which engages with the advertising cloth 10. By setting the third groove 21, the second clamping device 4 and the advertising cloth 10 are engaged.

[0039] The second clamping device 4 is also provided with a fourth groove 22, which slides with the buckle 18; by providing the fourth groove 22, the second clamping device 4 and the first clamping device 3 can be coordinated.

[0040] The upper clamping strip 15 and the lower clamping strip 16 are each provided with a stop block 23 at one end. The outer diameter of the stop block 23 is larger than the outer diameter of the upper clamping strip 15 and the lower clamping strip 16. By providing the stop block 23, the upper clamping strip 15 and the lower clamping strip 16 are prevented from disengaging when they cooperate with the first clamping device 4, thereby making the advertising cloth 10 more stable.

[0041] The third groove 21 has a fifth groove 24 near the stop block 23, and the fifth groove 24 cooperates with the stop block 23. By setting the fifth groove 24, the second clamping device 4 cooperates with the two clamping bars, thus preventing the two clamping bars from detaching from the second clamping device 4.

[0042] Working principle: This device uses two clamping devices, which are limited by the limiting groove 12 to prevent them from falling off the light box 1. Then, the two clamping devices are separated by the guide groove 11, thus clamping the advertising cloth 10. When the two clamping devices are separated, the advertising cloth 10 is clamped and arranged, making the cooperation between the advertising cloth 10 and the light box smoother. This makes the disassembly and assembly of the advertising cloth 10 more convenient and faster, effectively improving the disassembly and assembly efficiency of the advertising cloth 10. Furthermore, by setting the guide 6 and the elastic element 7, the advertising cloth 10 can automatically retract when the motor 9 is de-energized, effectively improving the disassembly efficiency of the advertising cloth 10.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any variations or modifications may be made to the implementation of the present invention without departing from the stated principles.
