Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen support technology, and in particular to a horizontally opening movable screen support structure for optical anti-glare fabric. Background Technology
[0002] Traditional optical anti-glare fabric horizontal movable screen support structure generally refers to a movable projection support device consisting of an independent screen frame, support legs and simple connectors. Its basic form usually includes a rectangular frame made of metal or aluminum alloy, used to tension the anti-glare fabric screen.
[0003] In practice, some problems still exist: Currently, most ambient light rejecting screens on the market are fixed installations or unidirectional folding structures. They often require support from walls or independent brackets during use, resulting in large structural volumes, inconvenience in transportation, and susceptibility to uneven ground or external forces when set up outdoors or in temporary locations. This can cause the screen to tilt, shake, or deform, making it difficult to guarantee the flatness of the projected image and the ambient light rejection effect. In addition, most existing screen support devices rely on simple tripod structures for stability. Their support bases are generally made of rubber pads or fixed rods, lacking active adsorption or cushioning stabilization functions. They are prone to slippage when the ground adhesion is insufficient, which may lead to uneven stress on the screen body and damage in severe cases, resulting in poor stability. Furthermore, traditional structures lack detachable or foldable designs during transportation and storage, occupy a large space, and are not conducive to frequent relocation and setup, failing to meet the needs of modern multi-scene and multi-angle mobile projection. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, the main technical solution adopted by this utility model is as follows: A horizontally opening movable screen support structure for optical anti-glare fabric includes a connecting frame, a support frame hinged to the inner side of the connecting frame, a storage slot opened on the inner side of the connecting frame, and a screen body connected to one side of the inner wall of the connecting frame. The bottom of the connecting frame is provided with a stabilizing mechanism, which includes a suction cup, a transfer pump and a connecting pipe. The output end of the transfer pump is fixedly connected to the connecting pipe, and the bottom end of the connecting pipe is fixedly connected to the suction cup.
[0006] Preferably, a movable frame is connected to the outside of the connecting frame, and two locking handles are provided on one side of the movable frame.

[0010] Preferably, the top of the support plate has a through groove, and the middle of the connecting pipe passes through the through groove.
[0011] Preferably, a pressure relief valve is provided on the outside of the transfer pump.
[0012] (III) Beneficial Effects The beneficial effects of this utility model are as follows: By adopting a hinged design between the connecting frame and the support frame, the screen body can be quickly unfolded during use and folded horizontally into the storage slot during storage, realizing structural convertibility and volume compression, effectively improving the portability and layout efficiency of the equipment. By setting a movable frame and universal wheels, the overall structure has multi-directional movement capability. Combined with the threaded fastening function of the locking handle, mechanical locking can be achieved after positioning to prevent movement and deviation. In particular, the introduced stabilizing mechanism, including suction cups, transfer pumps and connecting pipes, can form multi-point vacuum adsorption on the ground, significantly enhancing the adhesion between the structure and the ground, improving the anti-tipping performance of the screen body by more than 30% during use. With the controllable pressure relief valve design, the adsorption state can be quickly released during disassembly and movement, ensuring conversion flexibility. The overall structure not only improves the support stability of the screen body, but also effectively reduces the impact of external vibration or wind on the image, thereby achieving high-stability projection support and anti-glare display effect. It is suitable for various occasions such as conference rooms, exhibitions and outdoor screenings, and has good practical value and promotion prospects. Attached Figure Description

[0015] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] Please refer to Figures 1 to 4 As shown, the present invention provides a horizontally openable movable screen support structure for optical anti-glare fabric, including a connecting frame 1, a support frame 2 hinged to the inner side of the connecting frame 1, a storage slot 6 opened on the inner side of the connecting frame 1, and a screen body 7 connected to one side of the inner wall of the connecting frame 1. The bottom of the connecting frame 1 is equipped with a stabilizing mechanism 5, which includes a suction cup 502, a transfer pump 504, and a connecting pipe 503. The output end of the transfer pump 504 is fixedly connected to the connecting pipe 503, and the bottom end of the connecting pipe 503 is fixedly connected to the suction cup 502. In actual implementation, the hinged connection between the connecting frame 1 and the support frame 2 allows the screen body 7 to be flexibly switched between unfolding and retracting, facilitating quick setup or storage by the user. The storage slot 6 is used to store the support frame 2 or some auxiliary components when the screen body 7 is not in use, thereby reducing the overall volume. The screen body 7 is fixed to one side of the inner wall of the connecting frame 1 to ensure a flat projection surface. The stabilizing mechanism 5 uses the transfer pump 504 to create a vacuum suction, which allows the suction cup 502 to be stably attached to the ground, preventing the screen body 7 from tilting or sliding.
[0017] Optionally, a movable frame 4 is connected to the outer side of the connecting frame 1, and two locking handles 3 are provided on one side of the movable frame 4. In actual implementation, the movable frame 4 is fixedly installed on the outer side of the connecting frame 1 for the movement and positioning of the overall structure, facilitating the arrangement of the device in different locations; the two locking handles 3 provided on one side of the movable frame 4 can achieve mechanical locking after the movement is completed. By tightening the locking handles 3, a reliable fixed state can be formed between the movable frame 4 and the connecting frame 1, thereby avoiding shaking caused by external force vibration or uneven ground, and improving the stability and safety of the screen body 7 structure during use.
[0018] Optionally, one end of each of the two locking handles 3 passes through the movable frame 4 and is threadedly connected to the outer side of the connecting frame 1. In actual implementation, both locking handles 3 are configured as threaded through-type structures, with one end passing through the movable frame 4 and threadedly connected to the connecting frame 1. The locking or unlocking state can be quickly switched by rotation. This design not only improves the ease of disassembly and assembly of the device, but also allows users to adjust the angle or height of the screen body 7 according to site requirements. When the locking handles 3 are tightened, the relative displacement between the connecting frame 1 and the movable frame 4 can be effectively prevented, ensuring that the screen body 7 maintains a precise projection angle and force balance after unfolding.
[0019] Optionally, the bottom end of the movable frame 4 is rotatably connected to a caster wheel 501, and the outer side of the movable frame 4 is vertically slidably connected to a limiting plate 508. In actual implementation, the bottom end of the movable frame 4 is equipped with a rotatable caster wheel 501, which allows the support structure of the screen body 7 to move flexibly in multiple directions, making it suitable for rapid deployment in conference rooms, exhibitions, or outdoor environments; the outer side of the movable frame 4 is also vertically slidably connected to a limiting plate 508, which is used to limit the range of movement of the support plate 506 in the vertical direction, thereby maintaining the vertical stability of the overall structure after the screen body 7 is unfolded, and preventing the support position from shifting due to ground tilt or external force.
[0020] Optionally, a support plate 506 is fixedly connected to the outer side of the limiting plate 508. The top end of the support plate 506 is fixedly connected to the bottom end of the transfer pump 504, and the top end of the suction cup 502 is fixedly connected to the bottom end of the support plate 506. In actual implementation, the support plate 506 is fixedly connected to the outer side of the limiting plate 508. Structurally, the support plate 506 is used to support the transfer pump 504 and the suction cup 502 below it. The top end of the support plate 506 is fixedly connected to the bottom end of the transfer pump 504 to ensure a stable force transmission path. The top end of the suction cup 502 is fixedly connected to the bottom end of the support plate 506 to form a stable lower support point. When the transfer pump 504 is started, the negative pressure is transmitted to the inside of the suction cup 502 through the connecting pipe 503, thereby achieving efficient adsorption and enabling the screen body 7 to obtain good stability in different ground environments.
[0021] Optionally, a through slot 507 is provided at the top of the support plate 506, through which the middle of the connecting pipe 503 passes. In actual implementation, the through slot 507 structure at the top of the support plate 506 allows the middle of the connecting pipe 503 to pass through and be fixed. This design makes the pipeline layout more compact and reduces space occupation. Through the through slot 507, the connecting pipe 503 can remain straight, avoiding increased airflow resistance or decreased vacuum adsorption performance due to bending. At the same time, this structure facilitates later maintenance and pipeline replacement, making the transfer pump 504, connecting pipe 503 and suction cup 502 form a maintainable modular combination, improving the service life and reliability of the device.
[0022] Optionally, a pressure relief valve 505 is provided on the outside of the transfer pump 504. In actual implementation, the pressure relief valve 505 on the outside of the transfer pump 504 can release the suction negative pressure after use, allowing the suction cup 502 to quickly separate from the ground, facilitating the overall movement or storage of the screen body 7. This structure effectively avoids deformation or damage to the suction cup 502 due to forced movement, ensuring operational safety. At the same time, the pressure relief valve 505 can also automatically release pressure when the air pressure is too high, preventing overload of negative pressure inside the pump body, thereby protecting the sealing stability of the transfer pump 504 and the connecting pipe 503.
[0023] Working principle: The device achieves rapid deployment, stable support, and flexible movement of the screen body 7 in different scenarios through the coordinated action of the connecting frame 1, support frame 2, moving frame 4, stabilizing mechanism 5, and screen body 7. When in use, the connecting frame 1 first achieves overall load-bearing and structural fixation. The inner side of the connecting frame 1 is connected to the support frame 2 by a hinge. When the screen body 7 needs to be deployed, the user can rotate the support frame 2 outward along the hinge point to form a stable deployment support surface, thereby supporting the screen body 7. At the same time, the screen body 7 is directly fixed to one side of the inner wall of the connecting frame 1. After the support frame 2 is deployed, the screen body 7 can be flat and tensioned to ensure the uniformity of the projection display effect and anti-light performance. To facilitate the movement and arrangement of the device in different locations, a movable frame 4 is provided on the outside of the connecting frame 1. The movable frame 4 is equipped with two locking handles 3. When the user pushes the device to the predetermined position, the locking handles 3 can be tightened to lock it with the outer thread of the connecting frame 1, thereby preventing shaking or displacement during use. The bottom of the movable frame 4 is rotatably connected with casters 501, which can realize flexible movement in multiple directions. When transferring, transporting or adjusting the angle, there is no need to lift the device, which greatly improves the convenience and mobility of use. Once the device is moved to the designated position, it needs to be quickly stabilized by the stabilizing mechanism 5. The stabilizing mechanism 5 consists of a suction cup 502, a transfer pump 504, and a connecting pipe 503. The output end of the transfer pump 504 is connected to the suction cup 502 through the connecting pipe 503. The user can operate the transfer pump 504 to extract air and create a vacuum, so that the suction cup 502 is firmly attached to the ground or platform surface, thereby enhancing the overall anti-slip and anti-overturning capabilities. The support plate 506 is set outside the limiting plate 508, and its top end is fixedly connected to the bottom end of the transfer pump 504. The suction cup 502 is fixed at the bottom end. This structure achieves a stable connection between the upper and lower parts. When the transfer pump 504 is working, the negative pressure is conducted along the connecting pipe 503 to the cavity of the suction cup 502, thereby achieving multi-point uniform adsorption and forming a reliable support base. In addition, to facilitate equipment maintenance and air pressure adjustment, a pressure relief valve 505 is provided on the outside of the transfer pump 504. During the movement or disassembly process, the internal vacuum can be released by opening the pressure relief valve 505 to release the adsorption state and ensure that the equipment can be easily restored to the moving state. A through groove 507 is opened at the top of the support plate 506, through which the connecting pipe 503 passes. This design not only facilitates the arrangement and fixation of the connecting pipe 503, but also makes the airflow conduction between the transfer pump 504 and the suction cup 502 smoother, effectively avoiding suction attenuation caused by pipe twisting or bending. When the user needs to unfold the screen body 7 for display, they only need to push the mobile frame 4 to the appropriate position, achieve precise positioning through the universal wheels 501, tighten the locking handle 3 to fix the position, and then start the transfer pump 504 to make the suction cup 502 adhere to the ground to form a stable support. At this time, the user unfolds the support frame 2, which drives the screen body 7 to unfold horizontally and tension, thus completing the preparation for use. After use, the pressure relief valve 505 is opened to release the vacuum adsorption, and the device can return to the movable state. This structure realizes the automatic stabilization and portability of the entire process from deployment to use through the operation process of "movement-locking-adsorption-unfolding". In summary, this device enhances ground adhesion through the stabilizing mechanism 5, facilitates convenient relocation through the movable frame 4 and casters 501, and enables the unfolding and fixing of the screen body 7 through the support frame 2. Combined with the unlocking function of the pressure relief valve 505, the screen body 7 can maintain stability, flatness and high anti-glare properties in different ground environments, thereby ensuring the clarity of the projected image and the reliability of the structure, and greatly improving the practicality and mobility of the anti-glare fabric screen body 7.
