Description

Technical Field

[0001] This utility model relates to the field of multimedia equipment technology, specifically to a magnetically attached smart advertising door that allows for quick replacement of advertising images. Background Technology

[0002] Intelligent advertising gates are modern devices that integrate advertising display and access control functions, and are widely used in communities, shopping malls, and other places. They possess the traditional functions of passage and security doors, while also displaying advertising content through areas on the gate itself. This allows advertising information to spread naturally with the flow of people, making them a convenient information carrier and adding both practical and promotional functions to public spaces.

[0003] Utility model patent CN213483364U discloses an advertising door that facilitates the replacement of advertising billboards. This advertising door includes an advertising door and pressure strips. A glass panel is fixedly installed on the inner side of the advertising door. The pressure strips are located on the front side of the glass panel and contact it. A snap fastener is fixedly installed on the front side of the advertising door, contacting the front side of the pressure strips. By setting the pressure strips, when laying the advertising paper, the advertising paper is first attached close to the glass panel. Then, the four pressure strips are pulled from the center outwards, flattening the advertising paper and simultaneously squeezing out air bubbles and water vapor between the advertising paper and the glass panel. The pressure strips are then secured with the snap fasteners. This method of replacing advertising paper is faster and more convenient than the traditional pasting method; the pressure strips can be directly removed for replacement, achieving a better installation effect.

[0004] The existing advertising gate, which facilitates the replacement of billboards, requires the use of multiple clips to secure the pressure strip when replacing smaller advertisements. The pressure strip has a large clamping range for small advertisements, which can easily cause excessive stress on the edges of the advertisement paper, resulting in wrinkles. Furthermore, the connection between the pressure strip and the clips involves many steps during the assembly and disassembly process, making it inconvenient. Therefore, we propose a magnetically-assisted smart advertising gate for quick replacement of advertisement images. Utility Model Content

[0005] The purpose of this invention is to provide a magnetically attached smart advertising door that allows for quick switching of advertising images, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A smart advertising door with magnetic fast-changing advertising images includes a door body with an advertising door inside. The advertising door includes a fixed door frame fixed in the door body and a movable door frame hinged to the edge of the fixed door frame. A pair of advertising paper clamping mechanisms are slidably connected inside the fixed door frame. The two advertising paper clamping mechanisms are symmetrically distributed vertically inside the fixed door frame and clamp the top and bottom ends of the advertising paper respectively. The advertising paper clamping mechanisms can move vertically within the fixed door frame. Each advertising paper clamping mechanism includes a clamping seat slidably connected to the fixed door frame and a clamping plate hinged to the front end of the clamping seat. Locking handles are threaded to the left and right ends of the clamping seat. By tightening the locking handles, the ends of the locking handles can be pressed against the fixed door frame and the position of the clamping seat in the fixed door frame can be fixed. A magnetic strip is embedded in the front end face of the clamping seat, and an iron strip is embedded in the rear end face of the clamping plate. The iron strip corresponds to the position of the magnetic strip, and the advertising paper is clamped between the clamping seat and the clamping plate.

[0008] Preferably, transparent glass is embedded in the rear interior position of the fixed door frame and the front interior position of the movable door frame. The left end of the fixed door frame and the left end of the movable door frame are hinged together. A door lock is installed on the right edge of the front face of the movable door frame. The fixed door frame and the movable door frame are locked together by the door lock.

[0009] In this setup, the transparent glass clearly displays the advertising content and protects the advertising paper, the hinges allow the movable door frame to open and close flexibly, and the door lock enhances the stability of the closure.

[0010] Preferably, a groove for accommodating the advertising paper clamping mechanism is provided at the inner frame edge of the front end face of the fixed door frame;

[0011] In this design, the groove allows the advertising paper clamping mechanism to be flush with the surface of the fixed door frame, thus avoiding interference with the closing of the movable door frame.

[0012] Preferably, movable grooves are provided at the bottom edges of the grooves at both ends. The width of the movable grooves is less than the thickness of the clamp. The clamp is provided at both ends. The two protruding plates extend into the movable grooves on both sides respectively. The clamp is restricted between the two movable grooves by the protruding plates and can move vertically along the movable grooves.

[0013] In this configuration, the movable groove cooperates with the convex plate to provide a stable sliding path for the clamp, limit the lateral displacement of the clamp, and facilitate the adjustment of the clamping position.

[0014] Preferably, limiting plates are provided at the top and bottom edges of both ends of the clamping seat. The thickness of the limiting plates is greater than the thickness of the protruding plate. The limiting plates are used to prevent the protruding plate from coming out of the movable groove.

[0015] In this configuration, the limiting plate abuts against the edge of the movable groove to prevent the protruding plate from dislodging from the movable groove, thus improving the safety of the clamp sliding.

[0016] Preferably, the top end of the clamping seat and the top end of the clamping plate are hinged together. The front end face of the clamping seat is provided with a plurality of ridges and grooves. The direction of the ridges and grooves is parallel to the length direction of the clamping seat. The plurality of ridges and grooves are arranged at equal intervals along the width direction of the clamping seat. The rear end face of the clamping plate is provided with a plurality of protruding ridges. The number of ridges and ridges is equal to the number of ridges and their positions correspond one-to-one. The advertising paper is clamped between the ridges and ridges.

[0017] In this design, the hinge allows the clamping plate to rotate flexibly, and the grooves and protrusions work together to increase the friction on the advertising paper and reduce its slippage.

[0018] Preferably, a first fixing handle is fixed to the top of the clamping seat, and a second fixing handle is fixed to the top of the clamping plate. When the clamping seat and the clamping plate are closed, a gap is formed between the first fixing handle and the second fixing handle. By squeezing the first fixing handle and the second fixing handle, the second fixing handle can drive the clamping plate away from the clamping seat with the hinge as the fulcrum.

[0019] In this configuration, the first and second fixing handles work together to allow the hand to apply force to move the clamp away from the clamp seat, making it convenient to pick up and put down advertising paper.

[0020] Preferably, the second fixing handle is provided with a protrusion with a semi-cylindrical structure, and a through groove is provided on the protrusion. A bolt with a handle is connected to the first fixing handle. The handle portion of the bolt with a handle is located on the front side of the protrusion. The threaded portion of the bolt with a handle passes through the through groove and is threadedly connected to the first fixing handle. Tightening the bolt with a handle can replace the action of squeezing the first fixing handle and the second fixing handle.

[0021] In this design, the shank bolt engages with the boss and through slot, allowing the clamp to be moved away from the clamp when it is inconvenient to apply force by hand, thus increasing ease of operation.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This magnetic quick-change advertising gate uses two symmetrically distributed advertising paper clamping mechanisms, with magnetic clamps and plates to precisely hold the top and bottom ends of the advertising paper, reducing the possibility of wrinkles. At the same time, the magnetic strip and iron strip attract each other to achieve quick opening and closing. With the assistance of bolts with handles, the disassembly and assembly steps are simplified, making the operation more convenient. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] Please see Figures 1-3A magnetic quick-change advertising door includes a door body 100 made of aluminum alloy, an advertising door 200 installed in the door body 100, and an advertising door 200 including a fixed door frame 210 fixed in the door body 100 and a movable door frame 220 hinged to the edge of the fixed door frame 210. Both the fixed door frame 210 and the movable door frame 220 are made of high-strength plastic steel. The advertising paper is installed between the fixed door frame 210 and the movable door frame 220. The cooperation between the two can form a stable protective space for the advertising paper and reduce the direct adhesion of external dust to the advertising paper.

[0038] In this embodiment, transparent glass 211 with a light transmittance of over 90% is embedded in the inner rear end of the fixed door frame 210 and the inner front end of the movable door frame 220. The transparent glass 211 is made of tempered glass, which can clearly display the advertising content and also provide physical protection for the advertising paper, preventing it from being directly scratched. The left end of the fixed door frame 210 and the left end of the movable door frame 220 are hinged together. A door lock is installed on the right edge of the front end of the movable door frame 220. The door lock is made of brass. The fixed door frame 210 and the movable door frame 220 are locked together by the door lock, which can enhance the stability of the two after they are closed and prevent unnecessary opening from damaging the advertising paper.

[0039] Example 2

[0040] To facilitate the replacement of advertising paper of different sizes, such as Figures 2-7 As shown, a pair of advertising paper clamping mechanisms 300 are slidably connected inside the fixed door frame 210. The two advertising paper clamping mechanisms 300 are symmetrically distributed vertically inside the fixed door frame 210 and clamp the top and bottom ends of the advertising paper respectively. The clamping position can be flexibly adjusted according to the size of the advertising paper. The advertising paper clamping mechanism 300 can move vertically inside the fixed door frame 210. The advertising paper clamping mechanism 300 includes a clamping seat 310 slidably connected to the fixed door frame 210 and a clamping plate 320 hinged to the front end of the clamping seat 310. Both the clamping seat 310 and the clamping plate 320 are made of ABS engineering plastic, which has a certain toughness and can reduce hard damage to the advertising paper.

[0041] like Figures 2-5As shown, in this embodiment, a groove 212 for accommodating the advertising paper clamping mechanism 300 is provided at the inner frame edge of the front end face of the fixed door frame 210. The depth of the groove 212 is adapted to the thickness of the advertising paper clamping mechanism 300, so that the advertising paper clamping mechanism 300 remains flush with the surface of the fixed door frame 210 after installation, avoiding protrusions that affect the closing of the movable door frame 220. Movable grooves 213 are provided at the bottom edges of the grooves at both ends of the groove 212. The width of the movable grooves 213 is less than the thickness of the clamping seat 310. The clamp 310 has protruding plates 311 at both ends. These protruding plates 311 are made of the same ABS engineering plastic as the clamp 310 and are integrally molded, resulting in a stable structure. The two protruding plates 311 extend into the movable grooves 213 on both sides. The clamp 310 is constrained between the two movable grooves 213 by the protruding plates 311 and can move vertically along the movable grooves 213. The movable grooves 213 provide a stable sliding path for the protruding plates 311, ensuring that the clamp 310 does not shift during vertical movement. Limiting plates 316 are integrally formed at the top and bottom edges of both ends of the clamp 310. Their thickness is greater than that of the protruding plates 311. The limiting plates 316 abut against the edges of the movable grooves 213 to prevent the protruding plates 311 from dislodging from the movable grooves 213, enhancing the safety of the clamp 310 during sliding.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, specifically, the left and right ends of the clamp 310 are threaded with a locking handle 312 made of stainless steel. The end of the locking handle 312 is fitted with a rubber pad. By tightening the locking handle 312, the end of the locking handle 312 can be pressed against the fixed door frame 210. The friction force is used to fix the position of the clamp 310 in the fixed door frame 210. The rubber pad can increase the contact friction force, improve the fixing effect, and prevent the locking handle 312 from scratching the surface of the fixed door frame 210.

[0043] like Figures 4-7 As shown, the top of the clamp 310 and the top of the clamp 320 are hinged together by a hinge made of stainless steel, which is flexible and not easy to rust. A magnetic strip 313 is embedded in the front end of the clamp 310. The magnetic strip 313 is made of neodymium iron boron and has stable magnetic force. An iron strip 321 is embedded in the rear end of the clamp 320. The iron strip 321 is made of low carbon steel and is easily magnetized. The positions of the iron strip 321 and the magnetic strip 313 are corresponding. The advertising paper is clamped between the clamp 310 and the clamp 320. The attraction force of the magnetic strip 313 and the iron strip 321 can make the clamp 310 and the clamp 320 fit tightly together, so as to achieve a stable clamping of the advertising paper.

[0044] like Figures 5-7As shown, the front end face of the clamp 310 is provided with several grooves 314, the direction of which is parallel to the length direction of the clamp 310. The grooves 314 are evenly spaced along the width direction of the clamp 310. The rear end face of the clamp 320 is provided with several protruding ridges 322, which are integrally formed with the clamp 320. The number of ridges 322 and grooves 314 are equal and their positions correspond one-to-one. The advertising paper is clamped between the ridges 322 and grooves 314. The cooperation between the grooves 314 and ridges 322 can increase the friction of the advertising paper and prevent the advertising paper from sliding during the clamping process.

[0045] like Figure 4 , Figure 5 and Figure 7 As shown, it is worth noting that the top of the clamp 310 is fixed with a first fixing handle 315, and the top of the clamp 320 is fixed with a second fixing handle 323. Both the first fixing handle 315 and the second fixing handle 323 are made of stainless steel and have anti-slip textures on the surface for easy gripping and force application. When the clamp 310 and the clamp 320 are closed, a gap is formed between the first fixing handle 315 and the second fixing handle 323. By squeezing the first fixing handle 315 and the second fixing handle 323, the second fixing handle 323 can be used as a hinge to move the clamp 320 away from the clamp 310, making it convenient to put in or take out advertising paper.

[0046] like Figure 4 , Figure 6 and Figure 7 As shown, the second fixing handle 323 is provided with a semi-cylindrical boss 3231, which is integrally formed with the second fixing handle 323. The boss 3231 is provided with a through groove 3232. The first fixing handle 315 is connected with a shank bolt 330, which is made of stainless steel. The shank of the shank bolt 330 is located on the front side of the boss 3231. The threaded part of the shank bolt 330 passes through the through groove 3232 and is threadedly connected to the first fixing handle 315. By tightening the shank bolt 330, the bolt shank can abut against the boss 3231, thereby moving the clamp 320 away from the clamp 310, replacing the action of pinching the first fixing handle 315 and the second fixing handle 323. This is suitable for use in scenarios where it is inconvenient to apply force with the hand. Meanwhile, when tightening the handle bolt 330, the clamp 320 remains away from the clamp seat 310, at which point the end of the advertising paper can be easily inserted between the clamp seat 310 and the clamp 320, thus facilitating the placement of the advertising paper.

[0047] In this embodiment of the magnetic quick-change advertising screen smart advertising door, when in use, firstly, according to the size of the advertising paper, loosen the locking handle 312, adjust the position of the two clamps 310 along the movable groove 213 so that the distance between them matches the top and bottom length of the advertising paper, and then tighten the locking handle 312 to fix the clamps 310; then, by pinching the first fixing handle 315 and the second fixing handle 323 or tightening the handle bolt 330, move the clamp 320 away from the clamp 310, and place the top and bottom ends of the advertising paper into the clamps respectively. The corresponding clamp 310 is placed between the clamping seat 310 and the clamping plate 320; then, the first fixing handle 315 and the second fixing handle 323 are loosened or the handle bolt 330 is loosened, and the clamping plate 320 is made to fit with the clamping seat 310 by the attraction force of the magnetic strip 313 and the iron strip 321. At this time, the protruding rib 322 is embedded in the rib groove 314, and the advertising paper is clamped and fixed; finally, the movable door frame 220 is closed and locked by the door lock, so that the advertising paper is within the protection range of the transparent glass 211 between the fixed door frame 210 and the movable door frame 220.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
