Description

Technical Field

[0001] This utility model relates to the field of billboard technology, and in particular to a storefront billboard that is designed to prevent falling off. Background Technology

[0002] Existing storefront billboards come in various forms, including flat, three-dimensional, and lightbox styles. The general purpose is to allow passersby to observe the business's billboards, learn about the business through them, and thus promote it. However, existing storefront billboards are not only prone to falling off, but also inconvenient to adjust the tilt angle of the billboards. Furthermore, billboards may sometimes be subjected to external forces and fall, causing unnecessary damage to pedestrians.

[0003] However, existing technologies, such as Chinese Publication No. CN219575127U, "Anti-Falling Storefront Billboard," which relates to the field of billboard structural design, disclose an anti-falling storefront billboard. This billboard includes a storefront wall, with a threaded connecting frame slidably connected to the lower inner wall of the storefront wall. A threaded rod is threadedly connected to the bottom of the right inner wall of the threaded connecting frame. Several insert rods are fixedly connected to the top front end of the threaded connecting frame, penetrating the outer wall of the storefront wall. The threaded connecting frame is slidably connected to a through hole in the inner wall of the storefront wall. An anti-falling telescopic plate is slidably connected to the inner front wall of the storefront wall near the lower side of the threaded connecting frame. The front end of the anti-falling telescopic plate penetrates the outer wall of the storefront wall and extends to the outside. In this invention, by setting up the anti-falling telescopic plate and blades, when the billboard body falls, the blades on both sides can first cut the connecting rope, causing the anti-falling telescopic plate to pop out, thereby catching the falling billboard body and preventing it from hitting passersby and causing unnecessary damage.

[0004] However, this device lacks an adjustable tilt angle structure, making it impossible to adjust the tilt angle according to the height of different storefronts and the distance from the street. This prevents pedestrians or vehicles from clearly seeing the content on the billboard under various lighting conditions, resulting in glare from direct sunlight. It also makes it difficult for passersby to see the advertising information clearly. Furthermore, the lack of multiple connection structures means that the device may fall and injure pedestrians due to external forces, causing unnecessary damage. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, such as the inability to adjust the tilt angle according to different storefront heights and distances from the street, the inability to ensure that pedestrians or vehicles can clearly see the content on the billboard under various lighting conditions, the glare caused by direct sunlight, the inability to make it easier for passersby to see the advertising information, and the lack of multiple connection structures, which may cause the device to fall and hit pedestrians, resulting in unnecessary losses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a doorway advertising sign that prevents falling, comprising a mounting plate, two first shaft plates fixedly connected to one side of the mounting plate, a first shaft block rotatably connected to the outer surface of the first shaft plate, a placement shell fixedly connected to the end of the first shaft block away from the first shaft plate, two second shaft plates fixedly connected to the side of the mounting plate near the first shaft plate, a rotating rod fixedly connected to the inner side of the two second shaft plates and extending out one end, a driven crank fixedly sleeved on the outer surface of the rotating rod, a connecting rod rotatably connected to the end of the driven crank away from the rotating rod, a second shaft block rotatably connected to the end of the connecting rod away from the driven crank, one side of the second shaft block fixedly connected to the outer surface of the placement shell, and an adjustment component provided at the extended end of the rotating rod to adjust the tilt angle according to the height of the doorway and the distance to the street. The driven crank, which rotates with the rotating rod, drives one end of the connecting rod, and the other end of the connecting rod pushes the placement shell through the second shaft block, causing the placement shell and the first shaft block to tilt and rotate on the outer surface of the first shaft plate.

[0007] In a preferred embodiment, the adjusting assembly includes a worm gear, one side of which is fixedly connected to one end of the rotating rod. A worm is meshed with the outer surface of the worm gear, and a power rod is fixedly embedded inside the worm. A rocker arm is fixedly connected to the top of the power rod, which can drive the power rod to rotate inside the protective shell. The worm, which rotates with the power rod, will drive the rotating rod to rotate inside the second shaft plate under the meshing action of the worm gear. The selection of a worm gear and worm wheel is not for efficiency but to improve the stability of the device operation.

[0008] In a preferred embodiment, a protective shell is fixedly connected to the side of the mounting plate near the first shaft plate. One side of the protective shell is rotatably connected to the outer surface of the rotating rod, and the outer surface of the power rod is rotatably connected to the inside of the protective shell. The power rod can be rotated inside the protective shell by a rocker arm.

[0009] In a preferred embodiment, the adjustment assembly further includes an active crank, one side of which is fixedly connected to one end of a rotating rod. An electric push rod is rotatably connected to the end of the active crank away from the rotating rod. The end of the electric push rod away from the active crank is rotatably connected to one side of the mounting plate. The electric push rod can also perform work by extending and retracting, which pushes the active crank and simultaneously drives the rotating rod to rotate inside the second shaft plate.

[0010] In a preferred embodiment, the interior of the placement shell is rotatably connected to two fixing rods, the outer surface of the fixing rods is fixedly connected to multiple fixing plates, and the inner surface of the placement shell is fixedly connected to a pressure plate.

[0011] In a preferred embodiment, a driven bevel gear is fixedly sleeved on the outer surface of the fixed rod, and a driving bevel gear is meshed with the outer surface of the driven bevel gear. The fixed rod has a certain self-locking property due to the gravity and friction of the fixed plate itself.

[0012] In a preferred embodiment, a connecting rod is fixedly connected inside the two active bevel gears, and a hand lever is fixedly connected to the outer surface of the connecting rod, which drives the connecting rod to rotate inside the stabilizing block.

[0013] In a preferred embodiment, two stabilizing blocks are rotatably connected to the outer surface of the connecting rod. One side of each of the two stabilizing blocks is fixedly connected to the inner surface of the housing. The connecting rod is rotated inside the stabilizing blocks by a hand lever. The driving bevel gear that follows the rotation of the connecting rod will drive the fixed rod and the fixed plate to rotate about the fixed rod as the axis under the meshing action of the driven bevel gear.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This utility model features a tilt angle adjustable structure, which can adjust the tilt angle according to the height of different storefronts and the distance from the street, so that pedestrians or vehicles can clearly see the content on the billboard under various lighting conditions, avoiding glare caused by direct sunlight. It also makes it easier for passersby to see the advertising information. The device has multiple connection structures to prevent it from falling and hitting pedestrians, causing unnecessary damage.
