Description

Technical Field

[0001] This utility model relates to the field of outdoor display screen installation, and specifically to an outdoor display screen protection device. Background Technology

[0002] Outdoor displays typically refer to display devices used in outdoor environments, often for advertising, information dissemination, and event venues. When outdoor events are held or when tourist attractions experience increased visitor traffic during holidays, it is often necessary to set up small displays on roadsides or intersections to provide essential information. However, because temporary displays are typically set up during periods of high foot traffic, and these temporary displays are usually simply tilted and fixed to metal supports, they may be accidentally knocked over by the flow of people during peak hours. These temporary outdoor displays lack protective devices and are easily damaged when they fall to the ground. Therefore, it is necessary to develop a device that can protect these temporary displays and prevent damage when they tip over. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an outdoor display screen protection device. It uses two U-shaped frames to enclose the display screen, and incorporates airbags at the four corners. Flexible strips and bottom corner protectors are also provided at the front and back, providing comprehensive protection for the outdoor display screen in the event of an accidental tipping over.

[0004] According to an embodiment of this utility model, an outdoor display screen protection device includes a U-shaped frame, two U-shaped frames, an airbag that covers the corner of the U-shaped frame, and a connecting mechanism located on the outer side of the end of the U-shaped frame. The U-shaped frames are assembled into a complete rectangular frame by the connecting mechanism. A clamping space is recessed inward on the inner side of the U-shaped frame, and a clamping mechanism is movably provided on one side of the clamping space. The clamping mechanism includes a fastening plate that can slide within the clamping space and a telescopic rod that is rotatably and vertically arranged on one side of the fastening plate. The outer wall of the telescopic rod is threaded, and a first screw hole is provided at a corresponding position on the side wall of the U-shaped frame. The telescopic rod is threaded into the first screw hole. The telescopic end of the telescopic rod extending to the outside of the U-shaped frame is also provided with a foot. A flexible strip is provided along the inner edge of the U-shaped frame on the other side where the telescopic rod is not provided.

[0005] The technical principle of this utility model is as follows: Two U-shaped frames, which can be combined to form a rectangular frame and have inwardly recessed clamping spaces on their inner sides, wrap around the edge of the outdoor display screen to provide initial protection. Then, airbags are installed at the corners of the U-shaped frames to provide a second layer of protection. When the display screen tilts, the U-shaped frames prevent the edges of the display screen from directly impacting the bottom surface, thus preventing damage to the internal components of the display screen. The airbags prevent the corners of the display screen from being impacted, avoiding direct damage. The two U-shaped frames are connected by a connecting mechanism, facilitating the installation and removal of the protective device and adapting to the protection needs of temporary outdoor display screens. The clamping spaces... An internal clamping mechanism is installed, utilizing a telescopic rod threaded to the side wall of the U-shaped frame and a fastening plate rotatably connected to the end of the telescopic rod located inside the U-shaped frame. This allows the fastening plate to press and fix the edge of the display screen when the telescopic rod is rotated, and it can also accommodate display screens of different thicknesses, increasing practicality. The telescopic rod located outside the U-shaped frame also has a bottom corner on its telescopic end, and a flexible strip is provided on the opposite side of the U-shaped frame. This ensures that the outdoor display screen is cushioned when it falls, whether it is tilted forward or backward. Through the above mechanism, the possibility of damage to the temporarily installed outdoor display screen when it is tilted is greatly reduced. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes an outdoor display screen protection device, including a U-shaped frame 1, of which two U-shaped frames 1 are provided, an airbag 2, the airbag 2 covering the corner of the U-shaped frame 1, and a connecting mechanism 3, which is disposed on the outer side of the end of the U-shaped frame 1. The U-shaped frames 1 are assembled into a complete rectangular frame by the connecting mechanism 3. A clamping space 11 is recessed inward on the inner side of the U-shaped frame 1, and a clamping mechanism 4 is movably disposed on one side of the clamping space 11. The clamping structure includes a fastening plate 41 that can slide within the clamping space 11 and a rotating and vertically disposed on the fastening plate 41. The telescopic rod 42 on the side has threads on its outer wall. The corresponding position of the side wall of the U-shaped frame 1 has a first screw hole 12. The telescopic rod 42 is threaded into the first screw hole 12. When the telescopic rod 42 rotates in the first screw hole 12, in order to avoid the hydraulic pressure causing the fastening plate 41 to rotate, the end of the telescopic rod 42 is rotatably connected to the side of the fastening plate 41 so that there is no interference. The telescopic end of the telescopic rod 42 extending to the outside of the U-shaped frame 1 is also provided with a foot. The other side of the U-shaped frame 1 without the telescopic rod 42 is also provided with a flexible strip 5 along the inner edge near the U-shaped frame 1.

[0020] The outdoor display screen 7 is initially protected by two U-shaped frames 1 that can be combined to form a rectangular frame and have inwardly recessed clamping spaces 11. Airbags 2 are then installed at the corners of the U-shaped frames 1 for a second layer of protection. When the display screen tilts, the U-shaped frames 1 prevent the edges of the display screen from directly impacting the bottom surface, thus avoiding damage to the internal components. The airbags 2 prevent impacts to the corners of the display screen, preventing direct damage. The two U-shaped frames 1 are connected by a connecting mechanism 3, facilitating the installation and removal of the protective device and meeting the protection needs of a temporary outdoor display screen 7. A clamping mechanism 4 is installed within the clamping spaces 11. The telescopic rod 42, which is threadedly connected to the side wall of the U-shaped frame 1, and the fastening plate 41, which is rotatably connected to the end of the telescopic rod 42 located inside the U-shaped frame 1, allow the fastening plate 41 to press and fix the edge of the display screen when the telescopic rod 42 is rotated. This mechanism can also accommodate display screens of different thicknesses, increasing practicality. The telescopic rod 42, located outside the U-shaped frame 1, is also provided with a bottom corner 43. On the opposite side of the U-shaped frame 1, there is a flexible strip 5. This ensures that the outdoor display screen 7 is cushioned when it falls, whether it is tilted forward or backward. Through the above mechanism, the possibility of damage to the temporarily installed outdoor display screen 7 when it is tilted is greatly reduced.

[0021] like Figure 1 and Figure 3 As shown, the outer side of the airbag 2 is arc-shaped, which can better fit the corner of the U-shaped frame 1. The interior is provided with reinforcing ribs 21, and air bubbles are formed between the reinforcing ribs 21. When the airbag 2 hits the ground, the reinforcing ribs 21 and the air bubbles absorb the impact force, thus protecting the corner of the display screen that is very easily damaged.

[0022] like Figure 1 and Figure 2 As shown, the connecting mechanism 3 further includes a connecting seat 31, a fixing knob 32, and a double-ended screw 33. Four connecting seats 31 are provided, respectively located on the outer side of the ends of the U-shaped frame 1. Each connecting seat 31 has a through-hole for the screw and a mounting groove 34 coaxial with the screw hole, parallel to the side of the frame. The fixing knob 32 has a second screw hole 35 corresponding to the double-ended screw 33 at its center. The fixing knob 32 is coaxially positioned within the mounting groove 34. The double-ended screw 33 is sequentially inserted into the screw hole, the mounting groove 34, and the second screw hole 35. This mechanism connects the two U-shaped frames 1. Different double-ended screws 33 can be selected for connection according to the size of the display screen, adapting to different screen sizes and increasing practicality. Figure 3 As mentioned above, the screw insertion hole penetrates the connector 31, so different lengths of double-ended screws 33 can be freely selected for connection.

[0023] like Figure 1 and Figure 3 As shown, the bottom of the clamping space 11 is further provided with a flexible layer 6, such as flexible rubber, which avoids direct contact between the outer edges of the display screen and the U-shaped frame 1, and also serves as a buffer.

[0024] like Figure 1 and Figure 3 As shown, further, the telescopic rod 42 is also provided with a spring 44 along the telescopic direction. The telescopic end located inside the telescopic rod 42 is fixedly connected to one end of the spring 44. Through the structure of the spring 44, the telescopic rod 42 can play a buffering role when the display screen tilts backward, absorbing the impact force to the greatest extent and avoiding accidental damage to the back panel of the outdoor display screen 7.

[0025] like Figure 1 and Figure 3 As shown, furthermore, the telescopic rod 42 located outside the U-shaped frame 1 is provided with opposite ear plates 45 on both sides of the telescopic rod 42. Through the ear plates 45, the operator can tighten the telescopic rod 42 more conveniently.

[0026] like Figure 1 and Figure 3 As shown, the flexible strip 5 has a trapezoidal cross-section, with the wider bottom part fixedly connected to the inner edge of the U-shaped frame 1. When the outdoor display screen 7 tilts forward, the top of the flexible strip 5 contacts the ground first, creating a certain gap between the screen surface and the ground, thus preventing damage to the screen from stones or other hard objects of different sizes on the ground.

[0027] Furthermore, the flexible strip 5 is made of flexible rubber material, and the U-shaped frame 1 can also be made of non-metallic materials such as rigid plastic, which reduces weight and improves portability on the one hand, and can also effectively absorb the force when impacted on the other hand.

[0028] Furthermore, the edge of the U-shaped frame 1 can also be provided with commonly used connecting plates, with holes provided on the connecting plates for fixing to the tripod or bracket on which the outdoor display screen 7 is placed with bolts. This is existing technology and will not be described in detail.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
