Description

Technical Field

[0001] This utility model relates to the field of interactive display technology, specifically a portable LED interactive display screen. Background Technology

[0002] LED displays are flat panel displays composed of small LED module panels. They are used to display various information such as text, images, videos, and recorded signals. They are characterized by high brightness, low operating voltage, low power consumption, large size, long lifespan, impact resistance, and stable performance. In particular, the high brightness and high weather resistance of LED displays have made them widely used in the advertising field. They are frequently seen in airports, shopping malls, hotels, high-speed rail stations, subways, cinemas, exhibitions, office buildings, etc., targeting customers with strong purchasing power and possessing enormous advertising value.

[0003] For example, Chinese Patent CN214037683U discloses a movable interactive LED display screen, including a frame structure, an LED display screen, a base, and casters. The casters are equipped with a protective cover, which is set on the outer periphery of the wheel body through a lifting mechanism. When the protective cover moves upward under the action of the lifting mechanism, the bottom of the protective cover moves away from the ground and switches to the rolling working position, which can realize the rotation of the wheel. When the protective cover moves downward under the action of the lifting mechanism, the bottom of the protective cover moves towards the ground until it is in a close-fitting state. At this time, the protective cover switches to the protective working position to prevent debris and dust from accumulating on the wheel body, and also has a limiting function.

[0004] In actual use, the LED display screens described in this solution are mostly exposed to the outside and lack effective protective measures, making them extremely susceptible to scratches from external objects, resulting in scratches and damage, which reduces the user experience and lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a movable LED interactive display screen to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A movable LED interactive display screen includes a moving component, an angle adjustment component, a protective component, and the LED interactive display screen. The angle adjustment component is disposed on the upper end of the moving component, the protective component is disposed outside the angle adjustment component, and the LED interactive display screen is disposed inside the protective component. The angle adjustment component is used to adjust the display angle of the LED interactive display screen, and the protective component is used to protect the LED interactive display screen. The protective component includes a connecting rod, one end of which is fitted with a protective shell. The LED interactive display screen is installed inside the protective shell. Fixed seats are installed on both sides of the bottom end of the protective shell, and a rotating seat is rotatably connected between a pair of fixed seats. A protective plate is installed on the upper end of the rotating seat, and one side of the protective plate is tightly fitted against the side of the protective shell away from the connecting rod.

[0008] Furthermore, a first socket is installed on both sides of the upper end of the protective shell, and a second socket is installed on both sides of the upper end of the protective plate. The first socket and the second socket are both provided with insertion holes, and a U-shaped insertion rod is inserted between a pair of insertion holes on the same side.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the first socket, the second socket, and the U-shaped plug, when the protective plate and the protective shell are in a closed state, the first socket and the second socket are close to each other. The U-shaped plug passes through the socket holes of the first socket and the second socket to connect the protective plate and the protective shell, forming a stable protective structure, preventing the protective plate from being opened accidentally, and improving the protective effect of the protective shell and the protective plate on the LED interactive display screen.

[0010] Furthermore, both ends of the U-shaped plug extend to the outside of the two insertion holes, and both ends of the U-shaped plug are provided with several threads, and both ends of the U-shaped plug are threaded with locking rings.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting threads on the outside of the two ends of the U-shaped plug and threading locking rings, the U-shaped plug and locking rings can be tightened and fixed to prevent the plug from loosening and falling off, ensuring that the protective plate and the protective shell are firmly connected. When the locking rings are unscrewed, a pair of U-shaped plugs are pulled to both sides to separate the two U-shaped plugs from the two sets of first and second sockets respectively, so that the protective plate and the protective shell can be in an open state.

[0012] Furthermore, a mounting base is installed at the upper center of the protective plate, and the mounting base has a threaded hole inside.

[0013] Furthermore, the angle adjustment assembly includes a chassis with a circular hole at its center. A column is rotatably connected inside the circular hole. The outside of the column is fixedly connected to the end of the connecting rod away from the protective shell. A threaded column is connected to the outside of the column below the connecting rod. A bolt is threaded inside the threaded column. The central axis of the threaded column is collinear with the central axis of the threaded hole of the mounting seat on the flipped protective plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, after unscrewing the bolts and separating the U-shaped plug from the first and second sockets, the protective plate is flipped downwards. The rotating seat installed at the bottom of the protective plate can rotate inside a pair of fixed seats. When the protective plate is vertically downwards under the action of gravity, the threaded hole of the mounting seat on the flipped protective plate is aligned with the threaded post. Then, the threaded post and the mounting seat are connected by bolts, thereby fixing the position of the flipped protective plate.

[0015] Furthermore, the column is fitted with a connecting seat on the outside near the chassis. The inner wall of the connecting seat is fixedly connected to the outer wall of the column. A second annular groove is formed at the bottom end of the connecting seat. A strong magnet is installed inside the second annular groove. A first annular groove is formed inside the upper end of the chassis. An electromagnet is installed inside the first annular groove.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, by using electromagnets and strong magnets in combination, when the electromagnet is energized, the electromagnet and the strong magnet are magnetically attracted to each other, and the strong magnet and the electromagnet attract and fix the column. When the power is on, it provides a strong fixing force. When the power is off, the electromagnet and the strong magnet no longer attract each other, and the column can be easily rotated to adjust the angle, so as to adjust the display angle of the LED interactive display screen.

[0017] Furthermore, the mobile component includes a plurality of connecting strips, all of which are mounted on the outside of the chassis, and each of the connecting strips has a caster wheel mounted on its bottom end.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of connecting strips and casters, the casters allow the device to move freely, facilitating rapid transfer to different sites, and the four connecting strips arranged in a ring enhance the stability of the chassis.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This movable LED interactive display screen, by setting a protective shell and a protective plate, provides protection for the LED interactive display screen when it is not in use, as the protective shell and protective plate are in a closed state. Simultaneously, when the protective plate and protective shell are in a closed state, the first and second sockets are close to each other. A U-shaped plug passes through the holes of the first and second sockets, connecting the protective plate and the protective shell to form a stable protective structure, preventing the protective plate from accidentally opening and improving the protective effect of the protective shell and protective plate on the LED interactive display screen. By setting threads on the outside of both ends of the U-shaped plug and threadedly connecting locking rings, the U-shaped plug and locking rings can be tightened and fixed, preventing… To prevent the plug rods from loosening and falling off, and to ensure a secure connection between the protective plate and the protective shell, when the ELD interactive display screen needs to be used, unscrew the locking ring and pull a pair of U-shaped plug rods to both sides to separate the two U-shaped plug rods from the two sets of first and second sockets respectively. This allows the protective plate and protective shell to be opened. Flip the protective plate downwards, and the rotating seat installed at the bottom of the protective plate can rotate inside a pair of fixed seats. When the protective plate is vertically downwards under the action of gravity, the threaded hole of the mounting seat on the flipped protective plate aligns with the threaded post. Then, use bolts to connect the threaded post and the mounting seat, thereby fixing the position of the flipped protective plate. This ensures that the protective plate will not affect the display of the LED interactive display screen during use. Attached Figure Description

Locking rings 39 are threaded to both ends of the U-shaped rod 38. A mounting base 310 is installed at the center of the upper end of the protective plate 35. The mounting base 310 has an internal opening... The threaded hole angle adjustment assembly 2 includes a chassis 21. A circular hole 24 is formed at the center of the chassis 21. A column 25 is rotatably connected inside the circular hole 24. The outside of the column 25 is fixedly connected to the end of the connecting rod 31 away from the protective shell 32. A threaded post 27 is connected to the outside of the column 25 below the connecting rod 31. A bolt 28 is threadedly connected inside the threaded post 27. The central axis of the threaded post 27 is collinear with the central axis of the threaded hole of the mounting seat 310 on the flipped protective plate 35. When the protective plate 35 and the protective shell 32 are in a closed state, the first socket 36 and the second socket 37 are connected. The protective plate 35 and the protective shell 32 are connected by a U-shaped insert 38 that passes through the holes of the first socket 36 and the second socket 37, forming a stable protective structure. This prevents the protective plate 35 from opening accidentally and improves the protective effect of the protective shell 32 and the protective plate 35 on the LED interactive display screen 4. Threads are provided on the outer ends of the U-shaped insert 38, and locking rings 39 are threaded onto them. The U-shaped insert 38 and locking rings 39 can be tightened to prevent the insert from loosening and falling off, ensuring a secure connection between the protective plate 35 and the protective shell 32.

When the protective plate 35 is vertically downward under the action of gravity, the threaded hole of the mounting seat 310 on the flipped protective plate 35 is aligned with the threaded post 27. Then, the threaded post 27 and the mounting seat 310 are connected by bolts 28, thereby fixing the position of the flipped protective plate 35.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see Figures 1-5This utility model provides a technical solution: a connecting seat 26 is sleeved on the outside of the column 25 near the chassis 21. The inner wall of the connecting seat 26 is fixedly connected to the outer wall of the column 25. A second annular groove is formed at the bottom end of the connecting seat 26, and a strong magnet is installed inside the second annular groove. A first annular groove 22 is formed inside the upper end of the chassis 21, and an electromagnet 23 is installed inside the first annular groove 22. The moving component 1 includes several connecting strips 11, all of which are installed on the outside of the chassis 21, and each of the connecting strips 11 has a universal wheel 12 installed at its bottom end. The movement is connected by the electromagnet 23. When used in conjunction with a strong magnet, the electromagnet 23 is magnetically attracted to the strong magnet after being energized. The strong magnet and the electromagnet 23 are attracted to fix the column 25, providing a strong fixing force when energized. When the power is off, the electromagnet 23 and the strong magnet are no longer attracted, and the column 25 can be easily rotated to adjust the angle, so as to adjust the display angle of the LED interactive display screen 4. Through the use of connecting strips 11 and casters 12, the casters 12 enable the device to move freely and facilitate quick transfer to different sites. There are four connecting strips 11, which are arranged in a ring to enhance the stability of the chassis 21.

[0032] Specifically, the working principle of this portable LED interactive display screen is as follows: In use, by setting up a protective shell 32 and a protective plate 35, when the LED interactive display screen 4 is not in use, the protective shell 32 and the protective plate 35 are in a closed state, protecting the LED interactive display screen 4. Simultaneously, when the protective plate 35 and the protective shell 32 are in a closed state, the first socket 36 and the second socket 37 are close to each other. A U-shaped insert 38 passes through the socket holes of the first socket 36 and the second socket 37, connecting the protective plate 35 and the protective shell 32 to form a stable connection. A fixed protective structure is used to prevent the protective plate 35 from opening accidentally, improving the protective effect of the protective shell 32 and the protective plate 35 on the LED interactive display screen 4. By setting threads on the outer ends of the U-shaped insert 38 and threadedly connecting locking rings 39, the U-shaped insert 38 and locking rings 39 can be tightened and fixed, preventing the insert from loosening and falling off, and ensuring a firm connection between the protective plate 35 and the protective shell 32. When the ELD interactive display screen needs to be used, first use the casters 12 to move the device to the designated position, then unscrew the locking rings 39 and pull a pair of... The U-shaped inserts 38 separate the two sets of first sockets 36 and second sockets 37 respectively, so that the protective plate 35 and the protective shell 32 can be opened. When the protective plate 35 is flipped downwards, the rotating seat 34 installed at the bottom of the protective plate 35 can rotate inside a pair of fixed seats 33. When the protective plate 35 is vertically downwards under gravity, the threaded hole of the mounting seat 310 on the flipped protective plate 35 aligns with the threaded post 27. Then, bolts 28 are used to connect the threaded post 27 and the mounting seat 310, thus enabling the flipped protective plate to rotate. The protective plate 35 is fixed in position so that it will not affect the display of the LED interactive display screen 4 during use. Through the cooperation of electromagnet 23 and strong magnet, when electromagnet 23 is energized, electromagnet 23 and strong magnet are magnetically attracted to each other. The strong magnet and electromagnet 23 are attracted to fix the column 25, providing strong fixing force when energized. When the power is off, electromagnet 23 and strong magnet are no longer attracted to each other, and the column 25 can be easily rotated to adjust the angle, so as to adjust the display angle of the LED interactive display screen 4.
