Description

Technical Field

[0001] This application relates to the field of billboard technology, and in particular to an elevator billboard that is easy to replace. Background Technology

[0002] With the acceleration of urbanization, elevators, as an important means of transportation in high-rise buildings, have gradually become a hot spot for advertising. Elevator billboards are favored by advertisers due to their precise audience targeting and long display time.

[0003] Existing elevator advertising boards typically use double-sided tape or silicone sealant to directly attach the advertising backing to the elevator wall. While this method is simple to install, it has significant drawbacks when replacing the advertisement: workers need to remove residual adhesive, which is not only time-consuming and labor-intensive, but may also affect the adhesion of the new advertisement due to the difficulty in thoroughly cleaning the adhesive residue. Therefore, a replacement-friendly elevator advertising board has been proposed to solve these problems. Utility Model Content

[0004] To address the aforementioned problem of inconvenient billboard dismantling, this application provides an elevator billboard that is easy to replace.

[0005] The elevator advertising board provided in this application adopts the following technical solution:

[0006] An easily replaceable elevator advertising board includes a mounting frame. Fixed shafts are rotatably connected to both sides of the inner cavity of the mounting frame. A cover plate is fixedly connected to one end of each fixed shaft. Strip blocks are fixedly connected to both ends of the bottom of the cover plate. Multiple springs are fixedly connected inside each strip block. A locking block is fixedly connected to one end of each spring. A clamping plate is fixedly connected to the bottom of each locking block. A positioning block is provided at the bottom of the clamping plate. The positioning block is fixedly connected to the mounting frame. A fixing strap is fixedly connected to one end of the top of the mounting frame. A Velcro hook surface is fixedly connected to the side of the fixing strap near the mounting frame. A Velcro rough surface is adhered to the surface of the Velcro hook surface. One side of the Velcro rough surface is fixedly connected to the mounting frame.

[0007] Preferably, the mounting frame has rotating holes on both sides of its inner cavity that are adapted to the fixed shaft, and the fixed shaft is rotatably connected to the rotating holes through bearings.

[0008] Preferably, both the hook and loop sides of the hook and loop fastener are rectangular, and both the hook and loop sides have edging at their edges.

[0009] Preferably, a dustproof sticker is fixedly connected to the surface of the cover plate, and the dustproof sticker is disposed at the joint between the mounting frame and the cover plate, and the thickness of the dustproof sticker is 0.2-1mm.

[0010] Preferably, the top of the mounting frame is provided with an observation window, which is made of acrylic sheet made of polycarbonate material.

[0011] Preferably, a soft pad is fixedly connected to the bottom of the clamping plate. The soft pad is made of silicone material and has a thickness of 2-5mm.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The advertisement is quickly clamped by a spring and a clamping plate. When installing the advertisement, pressing down the cover plate compresses the spring, and the clamping plate holds the advertisement in place. When replacing the advertisement, lifting the cover plate releases the spring's deformation and the clamping plate releases, making operation simple. Meanwhile, the combination of hook and loop fasteners enhances the stability of the cover plate after it is closed, preventing the advertisement from falling off. The overall structure improves the efficiency of advertisement replacement and ensures a secure fixation.

[0014] 2. Dustproof stickers are placed at the joint between the mounting frame and the cover plate to effectively prevent dust and debris from entering, keeping the advertisement clean and improving its display effect. Passengers inside the elevator can directly see the advertisement content through the viewing window, and the high light transmittance of the acrylic panel ensures a clear display of the advertisement image. A silicone pad is fixedly connected to the bottom of the clamping plate; when clamping the advertisement, the pad adheres tightly to the advertisement surface, increasing friction without damaging the advertisement. Simultaneously, the use of bearings makes opening and closing the cover plate easier and less strenuous, improving the user experience. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1-4 This utility model provides an easy-to-replace elevator advertising board, including a mounting frame 1. A fixed shaft 301 is rotatably connected to both sides of the inner cavity of the mounting frame 1. A cover plate 2 is fixedly connected to one end of the fixed shaft 301. Strip blocks 4 are fixedly connected to both ends of the bottom of the cover plate 2. Multiple springs 401 are fixedly connected inside the strip blocks 4. A locking block 402 is fixedly connected to one end of each spring 401. A clamping plate 403 is fixedly connected to the bottom of the clamping block 402. A positioning block 5 is provided at the bottom of the clamping plate 403. The positioning block 5 is fixedly connected to the mounting frame 1. A fixing strap 202 is fixedly connected to one end of the top of the mounting frame 1. A hook and loop fastener 203 is fixedly connected to the side of the fixing strap 202 closest to the mounting frame 1. A hook and loop fastener 204 is attached to the surface of the hook and loop fastener 203. One side of the hook and loop fastener 204 is fixedly connected to the mounting frame 1.

[0022] When installing the advertisement, apply adhesive to the hard-to-reach corners on the back of the advertisement, then stick it to the positioning block 5 for initial fixation. Next, press down the cover plate 2, which rotates around the mounting frame 1 via the fixing shaft 301. At this time, the strip block 4 moves down with the cover plate 2, compressing the spring 401, and the locking block 402 causes the clamping plate 403 to move down. When the clamping plate 403 contacts the positioning block 5, the elasticity of the spring 401 clamps the advertisement, thus securing it. The hook and loop fasteners 203 and 204 on the fixing strap 202 adhere to each other, further securing the cover plate 2 and preventing accidental opening. To replace the advertisement, peel off the hook and loop fasteners 203 and lift the cover plate 2. The spring 401 returns to its original shape, the clamping plate 403 releases, and the old advertisement can be removed. Place the new advertisement in the new cover plate and repeat the process to complete the replacement.

[0023] The advertisement is quickly clamped by the spring 401 and the clamping plate 403, which is simple to operate and easy to replace. The hook and loop fasteners 203 and 204 enhance the stability of the cover 2 after it is closed, preventing the advertisement from falling off. At the same time, it is also easy to open the cover 2. The overall structure improves the efficiency of advertisement replacement and is firmly fixed.

[0024] In a preferred embodiment, the inner cavity of the mounting frame 1 is provided with rotating holes on both sides that are adapted to the fixed shaft 301, and the fixed shaft 301 is rotatably connected to the rotating holes through bearings.

[0025] The use of bearings significantly reduces friction during rotation, extends the service life of the fixed shaft 301 and the mounting frame 1, and makes the opening and closing of the cover plate 2 easier and less strenuous, thus improving the user experience.

[0026] In a preferred embodiment, both the hook and loop fastener 203 and the loop fastener 204 are rectangular structures, and both the hook and loop fastener 203 and the loop fastener 204 have edging at their edges.

[0027] When the cover plate 2 is closed, the hook and loop fasteners 203 and 204 on the fastening strap 202 adhere to each other. The interlocking action between the hooks of the hook and loop fasteners 203 and the fibers of the 204 secures the fastening strap 202, further tightening the cover plate 2. The rectangular structure provides a large contact area between the hook and loop fasteners 203 and 204, offering sufficient adhesive force. The edge binding protects the edges of the hook and loop fasteners 203 and 204 from wear and tear, preventing hook breakage or fiber shedding.

[0028] In a preferred embodiment, a dustproof sticker 3 is fixedly connected to the surface of the cover plate 2. The dustproof sticker 3 is disposed at the joint between the mounting frame 1 and the cover plate 2, and the thickness of the dustproof sticker 3 is 0.2-1mm.

[0029] When the cover plate 2 is closed, the dustproof sticker 3 is tightly attached between the mounting frame 1 and the cover plate 2. The presence of the dustproof sticker 3 effectively prevents dust and debris from entering, keeps the advertisement clean, and enhances the display effect of the advertisement.

[0030] In a preferred embodiment, the top of the mounting frame 1 is provided with an observation window 201, which is made of an acrylic sheet made of polycarbonate material.

[0031] The viewing window 201 is installed at the top of the mounting frame 1, allowing passengers inside the elevator to directly view the advertising content. The acrylic panel, made of polycarbonate material, has high light transmittance, ensuring a clear display of the advertising image.

[0032] In a preferred embodiment, a soft pad is fixedly connected to the bottom of the clamp 403. The soft pad is made of silicone material and has a thickness of 2-5 mm.

[0033] When clamping plate 403 clamps the advertisement, the silicone pad at the bottom of clamping plate 403 comes into contact with the advertisement surface. The silicone material has good elasticity and flexibility. Under the elastic force of spring 401, the pad will deform slightly according to the shape of the advertisement surface, closely adhering to the advertisement surface and increasing the friction between the pad and the advertisement.

[0034] The foregoing description, with reference to preferred embodiments, provides an exemplary implementation of an easily replaceable elevator advertising board provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
