Description

Technical Field

[0001] This utility model relates to the field of advertising light box technology, and more specifically to an outdoor advertising light box snap-fit ​​device. Background Technology

[0002] In outdoor advertising light boxes, light boxes often use soft film or knife-coated cloth with good light transmission and strong flexibility as advertising cloth. The "slots" on the frame and the "adhesive strips / fasteners" on the edge of the cloth are interlocked to achieve nail-free and glue-free fixation. This method is disclosed by patent CN215577511U, but it is necessary to interlock from all sides and the adhesive strips must be fully embedded. Otherwise, the advertising cloth is easy to fall off or the image is uneven.

[0003] Fixing light boxes relies on manual labor, and the larger the light box, the lower the efficiency. If the adhesive strip is not embedded enough during operation, it can easily cause the image to bulge. Uneven light transmission under the light affects the display. At the same time, outdoor wind and rain can also cause the interlocking structure to fail. Strong winds may pry out the adhesive strip, causing the image to flip out or fall off, increasing maintenance costs and affecting advertising. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an outdoor advertising light box snap-fit ​​device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an outdoor advertising lightbox snap-fit ​​device, including a lightbox base, a fixed frame fixedly connected to the surface of the lightbox base, an advertising cloth covering the outer surface of the fixed frame, a positioning groove formed on the outer surface of the lightbox base, a fixing nail inserted into the positioning groove, the outer surface of the fixing nail penetrating the advertising cloth and extending into the positioning groove, an outer frame snapped onto the outer surface of the advertising cloth, an elastic frame strip and an elastic frame pad fixedly connected to the inner wall of the outer frame, the top diameter of the outer frame being smaller than the bottom diameter, square grooves formed on both sides of the outer frame, a wire-passing groove formed inside the outer frame, a positioning block fixedly connected to one end of the wire-passing groove, a rotating plate fixedly connected to the other end of the wire-passing groove, the rotating plate being rotatably connected inside the square groove, a spring fixedly installed on the surface of the positioning block near the rope, and a snap-fit ​​groove matching the positioning block formed on the outer surface of the fixed frame.

[0006] Furthermore, the bottom end of the positioning block away from the rope is arc-shaped, and the top of the positioning block abuts against the inner wall of the slot.

[0007] Furthermore, the outer surface of the rope is slidably connected to the inside of the threading groove, the rotating plate is "L" shaped, and the tip of the fixing nail is conical.

[0008] Furthermore, the outer surface of the positioning block is slidably connected to the inside of the outer frame, and the surface of the positioning block away from the rope extends to the inner wall of the outer frame.

[0009] Furthermore, both bottom ends of the rotating plate are fixedly connected to protrusions, which are rotatably connected to the inside of the outer frame. The rotating plate is rotatably connected to the inside of the square groove through the protrusions.

[0010] Furthermore, the elastic frame strip is a silicone frame, the surface of the elastic frame strip away from the outer frame is arc-shaped and abuts against the outer surface of the advertising cloth, and the elastic frame pad is a frame-shaped silicone pad.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model effectively solves the problem of image bulging caused by insufficient embedding of adhesive strips in traditional lightboxes by using a dual fixing structure of "initial positioning with fixing nails + secondary reinforcement with elastic components of the outer frame". The fixing nails penetrate the advertising cloth and are inserted into the positioning groove, initially fixing the edges and corners of the advertising cloth to the surface of the fixed frame to prevent the advertising cloth from shifting during subsequent operations. The elastic frame strip on the inner wall of the outer frame is made of arc-shaped silicone material, which can fit tightly against the surface of the advertising cloth when the outer frame is pressed down. It automatically and evenly flattens the four sides of the advertising cloth with the help of friction, ensuring that the display area of ​​the advertising cloth is wrinkle-free. At the same time, the design of the top diameter of the outer frame being smaller than the bottom diameter, combined with the squeezing action of the elastic frame pad, further enhances the fit between the advertising cloth and the fixed frame, reduces uneven light transmission under the light, and makes the advertising image clearer and more beautiful. In addition, the elastic frame pad can also seal the connection between the fixed frame and the outer frame, reduce the risk of outdoor rainwater seepage, protect the internal structure of the lightbox, and extend the service life of the device.

[0013] 2. Compared to the cumbersome operation of traditional light boxes that require gradually snapping the adhesive strips together from all sides, this device simplifies installation and replacement. During installation, the advertising cloth is initially secured with fixing nails, and then the outer frame is pressed down until the positioning block engages with the slot. This eliminates the need for manual alignment of the adhesive strips, significantly reducing operational difficulty. Even for large light boxes, it effectively improves installation efficiency. When replacing the advertising cloth, simply rotate the "L"-shaped rotating plate outwards and use a rope to pull the positioning block out of the slot to quickly remove the outer frame. Then, remove the fixing nails to replace the advertising cloth. The entire process requires no professional tools, saving manpower and time costs. At the same time, the arc-shaped design at the bottom of the positioning block facilitates automatic engagement with the slot when the outer frame is pressed down, while the spring structure ensures a tight engagement between the positioning block and the slot, reducing structural failure caused by strong outdoor winds and lowering the probability of the advertising cloth flipping out or falling off. This reduces maintenance frequency and costs, ensuring the continuity of advertising. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] An outdoor advertising lightbox snap-fit ​​device includes a lightbox base 1, a fixed frame 2 fixedly connected to the surface of the lightbox base 1, an advertising cloth 3 covering the outer surface of the fixed frame 2, a positioning groove 4 formed on the outer surface of the lightbox base 1, a fixing nail 5 inserted into the inside of the positioning groove 4, the outer surface of the fixing nail 5 penetrating the advertising cloth 3 and extending into the inside of the positioning groove 4, an outer frame 6 snap-fitted to the outer surface of the advertising cloth 3, an elastic frame strip 7 and an elastic frame pad 8 fixedly connected to the inner wall of the outer frame 6, the top diameter of the outer frame 6 being smaller than the bottom diameter, square grooves 9 formed on both sides of the outer frame 6, a wire-passing groove 10 formed inside the outer frame 6, a positioning block 13 fixedly connected to one end of the wire-passing groove 10, a rotating plate 12 fixedly connected to the other end of the wire-passing groove 10, the rotating plate 12 being rotatably connected inside the square groove 9, a spring 14 fixedly installed on the surface of the positioning block 13 near the rope 11, and a snap-fit ​​groove 15 matching the positioning block 13 formed on the outer surface of the fixed frame 2.

[0023] In this implementation scheme, the design of the top diameter of the outer frame 6 being smaller than the bottom diameter makes the outer frame 6 a trapezoidal structure that is narrower at the top and wider at the bottom. When it is fitted onto the fixed frame 2, the larger bottom diameter makes it easier for the outer frame 6 to be quickly fitted onto the fixed frame 2, while the smaller top diameter can provide a certain wrapping force to the fixed frame 2 after installation. Combined with the engagement of the positioning block 13 and the slot 15, this further enhances the tightness of the connection between the outer frame 6 and the fixed frame 2, reduces the swaying of the outer frame 6 caused by strong outdoor winds, improves the overall wind resistance performance of the structure, and ensures the stable display of the advertising cloth 3.

[0024] Specifically, the bottom end of the side of the positioning block 13 away from the rope 11 is arc-shaped, and the top of the positioning block 13 abuts against the inner wall of the slot 15.

[0025] In this implementation scheme, the arc-shaped bottom design allows the positioning block 13 to automatically slide into the slot 15 along the outer surface of the fixed frame 2 during the pressing of the outer frame 6, eliminating the need for precise manual alignment and reducing the difficulty of operation; the top of the positioning block 13 abuts against the inner wall of the slot 15, which can limit the upward displacement of the outer frame 6, prevent the outer frame 6 from loosening due to strong outdoor winds, enhance structural stability, and reduce the risk of the advertising cloth 3 flipping out or falling off.

[0026] Specifically, the outer surface of the rope 11 is slidably connected to the inside of the threading groove 10, the rotating plate 12 is "L" shaped, and the tip of the fixing nail 5 is conical.

[0027] In this embodiment, the rope 11 slides within the threading groove 10, ensuring that the rope 11 does not deviate when pulling the positioning block 13, and ensuring that the positioning block 13 can stably disengage from the slot 15, facilitating the quick disassembly of the outer frame 6 and improving the replacement efficiency of the advertising cloth 3.

[0028] The "L"-shaped rotating plate 12 increases the contact area for hand operation, making it easier to rotate and control the rotation angle. It can be operated without the need for professional tools, reducing labor costs.

[0029] The tapered tip of the fixing pin 5 can more easily penetrate the advertising cloth 3 and insert into the positioning groove 4, reducing the pulling damage to the advertising cloth 3. At the same time, the tapered structure can enhance the tightness of the connection between the fixing pin 5 and the positioning groove 4, preventing the fixing pin 5 from loosening and causing the advertising cloth 3 to shift.

[0030] Specifically, the outer surface of the positioning block 13 is slidably connected to the inside of the outer frame 6, and the surface of the positioning block 13 away from the rope 11 extends to the inner wall of the outer frame 6.

[0031] In this embodiment, the positioning block 13 slides inside the outer frame 6, which can ensure the stability of the movement direction of the positioning block 13 and avoid the inability to properly engage with the slot 15 due to the offset of the positioning block 13; the positioning block 13 extends to the inner wall of the outer frame 6, so that when the outer frame 6 is fitted onto the outer surface of the fixed frame 2, the positioning block 13 can directly contact the outer surface of the fixed frame 2, which facilitates quickly finding the position of the slot 15 and engaging it, shortening the installation time and improving the assembly efficiency.

[0032] Specifically, both sides of the bottom of the rotating plate 12 are fixedly connected with protrusions, which are rotatably connected to the inside of the outer frame 6. The rotating plate 12 is rotatably connected to the inside of the square groove 9 through the protrusions.

[0033] In this embodiment, the protrusion serves as a pivot point, enabling the rotating plate 12 to rotate stably within the square groove 9, preventing the rotating plate 12 from shifting or falling off during rotation. The rotating plate 12 is limited within the square groove 9 by the protrusion, reducing the entry of outdoor dust and rainwater into the cable tray 10, protecting the structure of the rope 11 and the positioning block 13, reducing the risk of component corrosion, extending the service life of the device, and preventing the rotating plate 12 from being damaged by external force collisions, thus reducing maintenance costs.

[0034] Specifically, the elastic frame strip 7 is a silicone frame, the surface of the elastic frame strip 7 away from the outer frame 6 is arc-shaped and abuts against the outer surface of the advertising cloth 3, and the elastic frame pad 8 is a frame-shaped silicone pad.

[0035] In this embodiment, the elastic frame strip 7 made of silicone material has good flexibility and friction. When the curved surface comes into contact with the advertising cloth 3, it can fit tightly against the outer surface of the advertising cloth 3. When the outer frame 6 is pressed down, the friction force can automatically flatten the four sides of the advertising cloth 3, avoiding wrinkles or bulges in the advertising cloth 3, ensuring that the advertising image is flat, reducing uneven light transmission under light, and improving the display effect.

[0036] The elastic frame pad 8 of the frame-shaped silicone pad can fill the gap between the outer frame 6 and the fixed frame 2 to achieve a sealing effect, prevent outdoor rainwater from seeping into the interior of the light box, protect the internal circuit and structural components of the light box, and extend the service life of the light box; at the same time, the squeezing action of the elastic frame pad 8 can further enhance the fit between the advertising cloth 3 and the fixed frame 2, prevent the edges of the advertising cloth 3 from curling up, and improve the stability of the fixation.

[0037] The working principle and usage process of this utility model are as follows: During assembly, the advertising cloth 3 is fitted onto the outer surface of the fixed frame 2, and the edges and corners of the advertising cloth 3 are pressed flat towards the side of the fixed frame 2. Then, the fixing nail 5 pierces the advertising cloth 3 and is inserted into the positioning groove 4, initially positioning the advertising cloth 3 on its outer surface. Then, the outer frame 6 is fitted onto the outer surface of the fixed frame 2. At this time, the surface of the elastic frame strip 7 abuts against the surface of the advertising cloth 3. Through the friction between the elastic frame strip 7 and the surface of the advertising cloth 3, when the outer frame 6 is pressed down, the outer frame 6 slides downward. Through the contact between the elastic frame strip 7 and the advertising cloth 3, the advertising cloth 3 can be automatically pressed down evenly around its perimeter to ensure the flatness of the display area on the surface of the advertising cloth 3. When the bottom of the elastic frame pad 8 is against the top of the fixed frame 2, the outer frame 6 continues to be released downward. At this time, the elastic frame pad 8 deforms until the outer surface of the positioning block 13 is engaged in the slot 15. The outer frame 6 is then fixed, and the connection between the fixed frame 2 and the outer frame 6 is sealed by the elastic frame pad 8. The compression between the elastic frame pad 8 and the advertising cloth 3 further increases the firmness of the advertising cloth 3.

[0038] When the advertising cloth 3 needs to be replaced, simply rotate the rotating plate 12 outwards to make it rotate outwards from the square groove 9. Through the traction of the rope 11 by the rotating plate 12, the positioning block 13 slides into the outer frame 6. At this time, the spring 14 is in a compressed state. After the positioning block 13 is completely disengaged from the slot 15, the outer frame 6 can be removed directly. Then, the fixing nail 5 can be removed from the positioning groove 4, and the advertising cloth 3 can be removed and replaced.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
