Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a holographic cylindrical screen that is easy to control interactively. Background Technology

[0002] Holographic imaging technology, as an advanced visual display method, has been widely used in recent years. Among them, cylindrical holographic screens can provide a 360-degree surround visual experience, and have unique advantages in exhibitions, advertising media, education and other fields. The immersive and technological feel they bring is highly favored by users.

[0003] However, the core display components that make up a holographic image, especially the cylindrical screen itself, are typically delicate in structure and easily damaged. In practical use, these screens are exposed to the environment and are susceptible to physical damage from dust, moisture, or accidental contact. Therefore, equipping the cylindrical screen with a protective structure is necessary.

[0004] Existing protective solutions often focus on robustness, such as using bolts or complex clip-on structures to secure the protective cover to the base and top cover. While this design provides protection, it makes installation and subsequent maintenance extremely cumbersome and inconvenient. Furthermore, as a display device, a cylindrical screen inevitably involves power cords, data cables, and other connecting cables. Current structures generally neglect the effective management of these cables, resulting in them hanging haphazardly or piling up externally. This not only severely impacts the simplicity, aesthetics, and technological feel that holographic images should present but also poses a tripping hazard to others.

[0005] Therefore, this utility model proposes a holographic cylindrical screen that is easy to control interactively in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a holographic cylindrical screen that is easy to control interactively. It aims to improve the problems of cumbersome and inconvenient installation of protective structures, inaccurate positioning, and lack of effective cable management that leads to messy cables, affecting aesthetics and safety.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a holographic cylindrical screen that is easy to interact with and control, comprising a base, a cylindrical screen and a top cover; the cylindrical screen is vertically mounted on the base, and the top cover is mounted on the top of the cylindrical screen; The holographic cylindrical screen that facilitates interactive control also includes: a protective mechanism and a limiting mechanism; The protective mechanism includes a transparent protective plate that surrounds the cylindrical screen circumferentially. A positioning block extending upwards is fixedly connected to the top of the transparent protective plate. A positioning groove for interlocking with the positioning block is formed on the lower surface of the top cover. A first strong magnetic ring is fixedly connected to the bottom of the transparent protective plate. A bottom mounting ring is fixedly connected to the outer wall of the base, and a second strong magnetic ring is fixedly connected to the bottom mounting ring. The first and second strong magnetic rings are fixed together by magnetic attraction. The limiting mechanism includes a limiting fixing block, which is fixedly connected to the upper surface of the base. Connecting plates are symmetrically fixedly connected to both sides of the limiting fixing block. A spring is provided between the connecting plate and the limiting ring, and the spring applies an elastic thrust to the limiting ring. Preferably, a rubber contact layer is fixedly connected to the inner side of the limiting ring facing the cable; Preferably, the spring is a compression spring, and the two ends of the spring abut against the inner sidewall of the connecting plate and the outer sidewall of the limiting ring, respectively. Preferably, the positioning block and the positioning groove are engaged by a detachable snap-fit ​​mechanism; Preferably, the bottom mounting ring is arranged circumferentially around the base; Preferably, both the first strong magnetic ring and the second strong magnetic ring are annular structures and are coaxially arranged; Preferably, the limiting mechanism includes two sets of symmetrically arranged clamping structures, each composed of the connecting plate, the spring, and the limiting ring, and the two sets of clamping structures together define the cable channel; Preferably, the base has a hollow structure, and the interior of the base houses a signal receiver for communicating with external sensing devices.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problems of fragile and easily damaged core screens of existing holographic cylindrical screens, cumbersome installation of protective covers, and inaccurate positioning by setting up a protective mechanism, using the positioning block at the top and the positioning groove on the top cover to fit together, and the first strong magnetic ring at the bottom and the second strong magnetic ring on the base to magnetically attract each other. It achieves the effects of rapid assembly, accurate positioning, and stable protection of the cylindrical screen.

[0009] 2. This utility model, by setting a limiting mechanism, utilizes a combination of a limiting fixing block, a connecting plate, a spring, and a limiting ring fixed on the base to solve the problem of messy and disorganized external cables in existing equipment, which affects aesthetics and safety. It achieves the effect of automatically clamping and organizing cables by using the spring to apply elastic thrust to the limiting ring, thus keeping the wiring neat and orderly.

[0010] 3. This utility model solves the problem of easy slippage or easy wear of the insulation layer when the cable is rigidly clamped by fixing a rubber contact layer to the inner side of the limiting ring. It achieves the effect of increasing friction to prevent the cable from slipping accidentally and providing elastic buffer to protect the cable from damage. Attached Figure Description

[0013] 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.

[0014] Reference Figures 1-5 The present invention provides an embodiment of a holographic cylindrical screen that is easy to interact with and control, comprising a base 3, a cylindrical screen 1 and a top cover 2. The cylindrical screen 1 is vertically mounted on the base 3, and the top cover 2 is mounted on the top of the cylindrical screen 1. The base 3 provides stable support for the entire device. It also includes a protective mechanism 4 and a limiting mechanism 5. The protective mechanism 4 is used to achieve rapid installation and comprehensive protection of the cylindrical screen 1, and the limiting mechanism 5 is used to limit and regulate the connecting cables. Specifically, the protective mechanism 4 includes a transparent protective plate 401, which is a cylindrical structure arranged around the cylindrical screen 1. The top of the transparent protective plate 401 is fixedly connected to an upwardly extending positioning block 402. The lower surface of the top cover 2 is provided with a positioning groove 403 that interlocks with the positioning block 402. Through the interlocking of the positioning block 402 and the positioning groove 403, the transparent protective plate 401 and the top cover 2 are precisely positioned and connected in the vertical and horizontal directions. The bottom end of the transparent protective plate 401 is fixedly connected to a first strong magnetic ring 404 as a corresponding adsorption structure. The outer side wall of the base 3 is fixedly connected to a bottom mounting ring 405, and a second strong magnetic ring 406 is fixedly connected to the bottom mounting ring 405. During installation, the first strong magnetic ring 404 and the second strong magnetic ring 406 are magnetically attracted and fixed to each other. This combination of structures utilizes the mechanical snap-fit ​​at the top and the magnetic adsorption at the bottom to ensure the stability and convenience of the installation of the transparent protective plate 401. The limiting mechanism 5 includes a limiting fixing block 501, which is fixedly connected to the upper surface of the base 3 and serves as the installation reference for the entire limiting mechanism 5. Connecting plates 502 are symmetrically fixedly connected to both sides of the limiting fixing block 501, and the arrangement of the two connecting plates 502 forms a basic cable receiving channel. A spring 503 is provided between the connecting plate 502 and the limiting ring 504. The spring 503 continuously applies an elastic thrust to the limiting ring 504, so that the limiting ring 504 can elastically clamp the cable. This elastic thrust ensures the adaptive clamping capability for cables of different diameters. In the protective mechanism 4, the positioning block 402 and the positioning groove 403 are specifically a detachable snap-fit ​​engagement. This structure ensures that the transparent protective plate 401 can be quickly aligned with the top cover 2 and reliably connected during installation, and is also convenient to disassemble. To achieve a firm fixation at the bottom, the bottom mounting ring 405 is arranged in a ring around the circumference of the base 3, providing a complete mounting base for the second strong magnetic ring 406. Both the first strong magnetic ring 404 and the second strong magnetic ring 406 are ring structures. In the assembled state, the first strong magnetic ring 404 installed on the transparent protective plate 401 and the second strong magnetic ring 406 installed on the bottom mounting ring 405 are coaxially arranged. This coaxial ring magnetic pole correspondence can generate a uniform and strong ring magnetic attraction field, so that the entire bottom end of the transparent protective plate 401 can be seamlessly and firmly adsorbed onto the bottom mounting ring 405, forming a reliable sealing structure. In the limiting mechanism 5, to enhance the clamping effect on the cable and protect the cable insulation layer, a rubber contact layer 505 is fixedly connected to the inner side of the limiting ring 504 facing the cable. The high coefficient of friction and elasticity of the rubber contact layer 505 can effectively prevent the cable from sliding and avoid rigid contact damage to the cable. In this embodiment, the spring 503 is specifically a compression spring. The two ends of the spring 503 elastically abut against the inner side wall of the connecting plate 502 and the outer side wall of the limiting ring 504, respectively. The elastic restoring force of the spring 503 continuously pushes the limiting ring 504 inward to clamp the cable. The limiting mechanism 5 in this embodiment includes two sets of symmetrically arranged clamping structures, which are respectively composed of the connecting plate 502, the spring 503 and the limiting ring 504. These two sets of clamping structures are arranged opposite to each other and jointly define the central cable channel, thereby stably constraining the cable in the central position and preventing the cable from swaying left and right. A rubber contact layer 505 is fixedly connected to the inner side of the limiting ring 504 facing the cable. The spring 503 is a compression spring, and its two ends elastically abut against the inner side wall of the connecting plate 502 and the outer side wall of the limiting ring 504, respectively. The positioning block 402 and the positioning groove 403 are engaged in a detachable snap-fit ​​engagement. The bottom mounting ring 405 is arranged in a ring around the circumference of the base 3. The first strong magnetic ring 404 and the second strong magnetic ring 406 are both ring structures and are coaxially arranged. The limiting mechanism 5 includes two sets of symmetrically arranged clamping structures, which are respectively composed of the connecting plate 502, the spring 503 and the limiting ring 504. The two sets of clamping structures jointly limit the cable channel. The base 3 is a hollow structure, and the interior of the base 3 accommodates a signal receiver that communicates with external sensing devices.

[0015] Working principle: When installing the protective mechanism 4, the operator aligns the top of the transparent protective plate 401 with the top cover 2, so that the positioning block 402 on the transparent protective plate 401 is inserted into the positioning groove 403 on the lower surface of the top cover 2, so as to achieve a detachable snap-fit ​​engagement, thereby completing the quick positioning and fixing of the top; then, the bottom end of the transparent protective plate 401 is brought close to the outer wall of the base 3, and the first strong magnetic ring 404 at the bottom end of the transparent protective plate 401 and the second strong magnetic ring 406 fixed on the bottom mounting ring 405 are fixed by magnetic attraction. This magnetic attraction, together with the snap-fit ​​engagement at the top, ensures that the transparent protective plate 401 provides a stable surrounding protection for the cylindrical screen 1. When the cable is being straightened, it is pressed into the limiting mechanism 5. The cable squeezes the limiting ring 504, which moves outward and compresses the spring 503. The connecting plates 502 fixed on both sides of the limiting fixing block 501 provide reverse support for the spring 503. After the spring 503 is compressed, it generates a continuous elastic thrust. This elastic thrust acts on the cable through the limiting ring 504. The rubber contact layer 505 on the inner side of the limiting ring 504 increases the friction and provides a buffer, thereby achieving adaptive elastic clamping and stable positioning of the cable and keeping the wiring straight. When the device is running, the cylindrical screen 1 displays a holographic image. Users can perform gesture operations through external sensing devices. The signals are received by the signal receiver housed inside the hollow structure of the base 3, thereby enabling interactive control of the holographic image.
