[0002] In various scenarios such as medical diagnosis and treatment, laboratory operations, food processing, and daily protection, protective isolation covers are important devices for isolating personnel from the external environment and blocking the spread of droplets, dust, and pollutants. Their core requirements are good transparency and observation, reliable protective performance, and ease of use and storage flexibility.

[0003] Currently, most protective isolation covers adopt an integrated structure, which is made of a fixed frame and a whole acrylic sheet spliced ​​together. Although it can meet the basic isolation and protection needs, the fixed size of the isolation cover occupies a lot of storage space when not in use. For storage environments with limited space, the storage convenience is extremely poor. Therefore, we need to propose a foldable and retractable hinged hardened acrylic sheet protective isolation cover component. Summary of the Invention

Through the cooperation of several sets of hinges, a mounting base frame, acrylic side panels, an acrylic back panel, and an acrylic front panel, the protective cover can be folded and stored. When the acrylic back panel and acrylic front panel are unfolded via the hinges, rotating the adjustment mechanism causes the positioning seat to descend and position the acrylic side panels and acrylic back panel, thereby reducing the storage volume of the cover and minimizing the storage space occupied, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a foldable and retractable hinged hardened acrylic protective cover assembly, comprising a cover body, the cover body being transparent, the cover body including a mounting base frame and several sets of hinges, acrylic side plates hinged to both sides of the mounting base frame, an acrylic back plate hinged to the rear end face of the mounting base frame, an acrylic front plate hinged to the front end face of the mounting base frame, an acrylic top cover rotatably connected to the top of the acrylic front plate, an adjustment groove provided on the lower surface of the acrylic top cover, a positioning seat for positioning the acrylic sheet slidably connected to the inner cavity of the adjustment groove, an adjustment mechanism for adjusting the position of the positioning seat provided on the upper surface of the acrylic top cover, and several sets of hinges all located within the inner cavity of the cover body.

[0006] For example, the adjustment mechanism includes an adjustment frame integrally formed on the upper surface of the acrylic top cover. The top of the adjustment frame has a movable hole, and an adjustment rod is slidably connected to the inner cavity of the movable hole. The bottom end of the adjustment rod passes through the acrylic top cover and is bonded and fixed to the upper surface of the positioning seat. The surface of the adjustment rod is provided with a support structure for pushing the adjustment rod downward.

[0007] For example, the support structure includes a support seat integrally formed on the surface of the adjusting rod, the surface of the support seat being slidably connected to the inner cavity of the adjusting frame, and a support spring being provided at the top of the support seat, and the support spring being sleeved on the surface of the adjusting rod.

[0008] For example, the inner sidewall of the adjustment frame is symmetrically provided with support grooves, and a support block is slidably connected to the inner cavity of the support groove. The support block is integrally formed on the surface of the support base.

[0009] For example, the surface of the adjusting rod is provided with a support hole, and the support hole is located in the inner cavity of the adjusting frame. A positioning pin is inserted into the inner cavity of the support hole, and a pull ring is rotatably connected to the top end of the adjusting rod.

[0010] For example, both sides of the positioning seat are integrally formed with limiting blocks, and the surface of the limiting blocks is slidably connected to the inner cavity of the adjustment groove.

[0011] For example, the lower surface of the positioning seat is symmetrically provided with sliding grooves on both sides, and a slider is slidably connected to the inner cavity of the sliding groove. The slider is integrally formed on the top of the acrylic side plate.

[0012] For example, the lower surface of the positioning seat is also provided with a positioning groove, and a positioning block is slidably connected to the inner cavity of the positioning groove. The positioning block is integrally formed on the top of the acrylic back plate.

[0013] For example, a rubber sealing ring is bonded and fixed to the lower surface of the mounting base frame, and the surface of the rubber sealing ring is provided with anti-slip texture.

[0014] For example, the top of the acrylic front panel is provided with a movable groove, the inner cavity of the movable groove is rotatably connected to a connecting seat, and the surface of the acrylic top cover is provided with a slot that matches the connecting seat, and the connecting seat is rotatably connected to the inner cavity of the slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a foldable, hinged, hardened acrylic protective cover assembly. Through the cooperation of several sets of hinges, a mounting base frame, acrylic side panels, an acrylic back panel, and an acrylic front panel, the protective cover can be folded and stored, reducing its size when stored. By placing the hinges within the inner cavity of the protective cover, exposed hinges are avoided, improving the overall aesthetics of the protective cover. An adjustment mechanism allows for the raising and lowering of a positioning seat, enabling it to position or release the acrylic side panels and back panel, allowing for quick folding and storage.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-7 This invention provides a technical solution: a foldable and retractable hinged hardened acrylic protective cover assembly, including a cover body 1, which is transparent. The cover body 1 includes a mounting base frame 110 and several sets of hinges 3. Acrylic side plates 111 are hinged to both sides of the mounting base frame 110 via hinges 3. An acrylic back plate 112 is connected to the rear end of the mounting base frame 110 via hinges 3. An acrylic front plate 113 is hinged to the front end of the mounting base frame 110 via hinges 3. An acrylic top cover 114 is rotatably connected to the top of the acrylic front plate 113. An adjustment groove 4 is provided on the lower surface of the acrylic top cover 114. A positioning seat 5 for positioning the acrylic plate is slidably connected to the inner cavity of the adjustment groove 4. An adjustment mechanism 2 for adjusting the position of the positioning seat 5 is provided on the upper surface of the acrylic top cover 114. Several sets of hinges 3 are all located in the inner cavity of the cover body 1. Furthermore, the main body 1 of the isolation cover connects the acrylic side panel 111, acrylic back panel 112, and acrylic front panel 113 to the mounting base frame 110 via several sets of built-in hinges 3, enabling the rotation and folding of each panel. At the same time, the top of the acrylic front panel 113 is rotatably connected to the acrylic top cover 114, allowing for simultaneous folding or unfolding operations. This allows the protective isolation cover to be folded and stored, reducing the space occupied when storing the protective isolation cover. Setting several sets of hinges 3 inside the cavity of the main body 1 of the isolation cover can increase the overall aesthetics of the protective isolation cover and prevent the hinges 3 from being exposed. When unfolding, the acrylic back panel 112, acrylic front panel 113, and acrylic side panels 111 on both sides are unfolded in sequence until each panel is perpendicular to the mounting base frame 110. Then, the acrylic top cover 114 is rotated so that it covers the top of the acrylic back panel 112 and the acrylic side panels 111. At this time, the acrylic top cover 114 is in contact with the top of each panel, initially forming a closed isolation space. The adjustment mechanism 2 is adjusted to push the positioning seat 5 downward, so that the four sides of the positioning seat 5 are tightly in contact with the surface of the acrylic side panels 111 and the acrylic back panel 112. This accurately positions and fixes each acrylic panel after unfolding, ensuring that the overall structure is stably formed after unfolding and will not shake or misalign, thus ensuring the isolation and protection effect. In this embodiment, to meet the visualization requirements in protective scenarios, the main body 1 of the isolation cover is made of high-transparency acrylic material (PMMA polymethyl methacrylate can be selected). This material not only has excellent light transmittance, allowing operators to clearly observe every move within the isolation area and avoid affecting operational efficiency due to obstructed vision, but also has the advantages of wear resistance, easy cleaning, and lightweight texture. In daily use, simply wiping with a clean cloth can quickly remove surface stains, droplets, or dust, maintaining a clear field of vision. At the same time, it can effectively block the spread of droplets, dust, pollutants, etc., building a solid protective barrier. Through the coordinated cooperation of the adjustment mechanism 2 and several sets of hinges 3, the main body 1 of the isolation cover can be folded or unfolded without the need for additional tools such as screwdrivers and wrenches, requiring only manual operation. This greatly improves the convenience of using the protective isolation cover, reduces the operational difficulty for operators, and is suitable for use by various groups of people.

[0023] In this embodiment, the mounting base frame 110 can be made of high-strength engineering plastics (such as ABS plastic, PC polycarbonate plastic) or lightweight metal materials (such as aluminum alloy, stainless steel). Regardless of the material used, the mounting base frame 110 can be made of sturdy material and moderate weight, which can stably bear the weight of the entire isolation cover, ensuring the stability of the overall structure, and is easy to move and transport, adapting to the placement needs of different scenarios, such as a treatment table in a hospital, an office desk, or a worktable in a restaurant.

[0024] Preferably, the adjustment mechanism 2 includes an adjustment frame 21, which is integrally formed on the upper surface of the acrylic top cover 114. The top of the adjustment frame 21 has a movable hole, and an adjustment rod 22 is slidably connected to the inner cavity of the movable hole. The bottom end of the adjustment rod 22 passes through the acrylic top cover 114 and is bonded and fixed to the upper surface of the positioning seat 5. The surface of the adjustment rod 22 is provided with a support structure for pushing the adjustment rod 22 downward. When the acrylic side plate 111 and the acrylic back plate 112 are both unfolded and fit against the inner cavity of the acrylic top cover 114, the support structure can be adjusted to push the adjustment rod 22 downward. The adjustment rod 22 simultaneously pushes the positioning seat 5 downward, so that the surface of the positioning seat 5 is tightly fitted against the surfaces of the acrylic side plate 111 and the acrylic back plate 112, thereby achieving precise positioning of the acrylic side plate 111 and the acrylic back plate 112, thus completing the unfolding operation of the protective isolation cover and ensuring that the isolation cover forms a closed and stable protective space. Specifically, when the isolation cover needs to be folded, the adjusting rod 22 is pulled upwards, and the adjusting rod 22 moves upwards along with the supporting structure. At the same time, the bottom end of the adjusting rod 22 moves upwards along with the positioning seat 5 until the positioning seat 5 slides completely into the inner cavity of the adjusting groove 4. After the positioning seat 5 and the adjusting groove 4 are in place, the positioning constraints on the acrylic side panel 111 and the acrylic back panel 112 can be released. At this time, the operator can fold the acrylic side panel 111, the acrylic back panel 112, and the acrylic front panel 113, thereby reducing the volume of the protective isolation cover and making it easier to store and transport.

[0025] Furthermore, the support structure includes a support seat 23 integrally formed on the surface of the adjusting rod 22. The surface of the support seat 23 is slidably connected to the inner cavity of the adjusting frame 21. A support spring 24 is provided at the top of the support seat 23 and is sleeved on the surface of the adjusting rod 22. The elastic force of the support spring 24 can achieve elastic pressing of the positioning seat 5, which can ensure that the positioning is firm. During assembly, the support seat 23 is pushed downward by the elasticity of the support spring 24. The support seat 23 moves downward with the adjusting rod 22 at the same time, so that the adjusting rod 22 pushes the positioning seat 5 at the bottom end out of the inner cavity of the adjusting groove 4, which cooperates to perform positioning and fixing operations on the acrylic side plate 111 and the acrylic back plate 112. Additionally, when the adjusting rod 22 is pulled upward, it can move the supporting seat 23 upward to compress the supporting spring 24, and at the same time move the positioning seat 5 upward, so that the positioning seat 5 follows into the inner cavity of the adjusting groove 4. When the positioning seat 5 is in place with the adjusting groove 4, the acrylic side plate 111 and acrylic back plate 112 are released. At this time, the acrylic side plate 111, acrylic back plate 112 and acrylic front plate 113 can be folded.

[0026] In this embodiment, the process of integrally molding the support base 23 and the adjusting rod 22 has the effect of strong structural integrity and is not easy to break or loosen.

[0027] In this embodiment, the support spring 24 is a cylindrical helical spring made of high-strength spring steel, which has the advantages of good elasticity, fatigue resistance and long service life. The support spring 24 is sleeved on the surface of the adjusting rod 22, which can limit the support spring 24 and prevent the support spring 24 from twisting or misaligning.

[0028] The two ends of the support spring 24 abut against the top of the support base 23 and the inner wall of the adjustment frame 21, respectively. When in a naturally extended state, the elastic force of the support spring 24 can continuously push the support base 23 downward, thereby driving the adjustment rod 22 and the positioning seat 5 to move downward synchronously, so as to achieve elastic pressing of the positioning seat 5. This elastic pressing method ensures firm positioning and avoids shaking of the acrylic sheets.

[0029] Preferably, the inner sidewall of the adjusting frame 21 is symmetrically provided with support grooves 6, and the inner cavity of the support groove 6 is slidably connected with a support block 7. The support block 7 is integrally formed on the surface of the support base 23. When the support base 23 moves up and down with the adjusting rod 22, the support block 7 slides synchronously along the support groove 6, limiting and guiding the movement trajectory of the support base 23 and the adjusting rod 22, avoiding the angle deviation of the support base 23 after being subjected to force, further improving the stability and accuracy of the movement of the adjusting rod 22, and ensuring that the positioning seat 5 can move smoothly and accurately fit each acrylic plate.

[0030] In addition, a support hole 8 is provided on the surface of the adjusting rod 22, and the support hole 8 is located in the inner cavity of the adjusting frame 21. A positioning pin 9 is inserted into the inner cavity of the support hole 8. A pull ring is rotatably connected to the top of the adjusting rod 22. When folding, pulling the pull ring moves the adjusting rod 22 upward. The adjusting rod 22 and the support seat 23 compress the support spring 24. When the adjusting rod 22 moves to the top of the adjusting frame 21 with the support hole 8, the positioning pin 9 can be removed and inserted into the inner cavity of the support hole 8. The surface of the positioning pin 9 fits against the top of the adjusting frame 21, which can prevent the adjusting rod 22 from falling down, thereby cooperating with the folding and storage operation of the protective isolation cover. Furthermore, when it is necessary to position the acrylic back panel 112 and the acrylic side panel 111, pull the pull ring upward to move the adjusting rod 22 upward, causing the support hole 8 to move upward, pulling the positioning pin 9 out of the inner cavity of the support hole 8, and then releasing the pull ring, which will release the support spring 24 to push the support seat 23 downward. The support seat 23 moves downward with the adjusting rod 22, causing the positioning seat 5 to be pushed downward out of the inner cavity of the adjusting groove 4 by the adjusting rod 22, thereby positioning the acrylic side panel 111 and the acrylic back panel 112.

[0031] Preferably, both sides of the positioning seat 5 are integrally formed with limiting blocks 10. The surface of the limiting blocks 10 is slidably connected to the inner cavity of the adjustment groove 4. When the positioning seat 5 moves, the limiting blocks 10 on both sides move with the positioning seat 5, so that the limiting blocks 10 slide in the adjustment groove 4. By cooperating with the adjustment groove 4, the positioning seat 5 can be limited around its perimeter, preventing the angle of the positioning seat 5 from shifting when it rises or falls. At the same time, the positioning seat 5 moves out of the inner cavity of the adjustment groove 4, limiting the movement position of the positioning seat 5, thereby further improving the stability of the positioning seat 5 when it moves.

[0032] Specifically, symmetrical grooves 11 are provided on both sides of the lower surface of the positioning seat 5. A slider 12 is slidably connected to the inner cavity of the groove 11. The slider 12 is integrally formed on the top of the acrylic side plate 111. Through the cooperation of the slider 12 and the groove 11, the acrylic side plate 111 moves with the slider 12 when unfolded. The groove 11 provides guidance for the slider 12, avoiding the acrylic side plate 111 from swaying or misaligning when unfolded. This ensures that the acrylic side plate 111 remains perpendicular to the mounting base frame 110 after unfolding, thus ensuring the overall stability of the isolation cover.

[0033] In addition, a positioning groove 13 is provided on the lower surface of the positioning seat 5. A positioning block 14 is slidably connected to the inner cavity of the positioning groove 13. The positioning block 14 is integrally formed on the top of the acrylic back plate 112. When the isolation cover is unfolded, the positioning seat 5 moves downward, so that the positioning block 14 slides into the positioning groove 13. Through the cooperation of the positioning groove 13 and the positioning block 14, the top of the acrylic back plate 112 is positioned and fixed, limiting the shaking of the acrylic back plate 112. The cooperation of the positioning groove 13 and the positioning block 14 can effectively fix the acrylic back plate 112. Together with the sliding groove 11 and the slider 12, it forms an all-round positioning, improving the stability of the overall structure of the protective isolation cover.

[0034] In addition, a rubber sealing ring 15 is bonded and fixed to the lower surface of the mounting base frame 110. The surface of the rubber sealing ring 15 is provided with anti-slip texture. The rubber sealing ring 15 can fill the gap between the mounting base frame 110 and the placement surface. The anti-slip texture on the surface of the sealing ring increases the friction between it and the placement surface, preventing the isolation cover from sliding, thereby improving the sealing effect of the bottom of the protective isolation cover. At the same time, the rubber sealing ring 15 is soft and can buffer the impact force during placement, protecting the mounting base frame 110 and the placement surface.

[0035] In this embodiment, the rubber sealing ring 15 can be made of high-quality rubber material that is resistant to high temperature, wear, and has good sealing performance. Specifically, silicone rubber or nitrile rubber can be selected. Silicone rubber has the advantages of high temperature resistance, low temperature resistance, aging resistance, and good sealing performance, and can adapt to different usage environments, especially suitable for medical, catering and other scenarios with high hygiene requirements. Furthermore, nitrile rubber has advantages such as wear resistance, oil resistance, and good sealing performance, making it suitable for scenarios with oil stains and high wear levels. It can be flexibly selected according to the actual application scenario.

[0036] The rubber sealing ring 15 is bonded and fixed to the lower surface of the mounting base frame 110 with high-strength environmentally friendly adhesive. The adhesive is strong and not easy to fall off. The environmentally friendly adhesive is odorless and non-toxic, and will not pollute the environment. It meets the hygiene requirements of various protective scenarios.

[0037] Preferably, the top of the acrylic front panel 113 is provided with a movable groove, and the inner cavity of the movable groove is rotatably connected to a connecting seat 16. The surface of the acrylic top cover 114 is provided with a slot that matches the connecting seat 16. The connecting seat 16 is rotatably connected to the inner cavity of the slot. Through the coordinated cooperation between the connecting seat 16, the movable groove and the slot, the acrylic front panel 113 and the acrylic top cover 114 can be flexibly folded and unfolded. When unfolded, a fixed angle can be maintained to ensure that the top cover can be stably placed on the top of each panel to form a closed isolation space. When folded, it can be folded synchronously with the front panel without occupying extra space. At the same time, this connection structure is hidden inside the component, which does not affect the overall aesthetics of the isolation cover, and can also prevent external collisions from damaging the connection parts and extend the service life of the component.

[0038] In this embodiment, the positioning pin 9 can be tied to the pull ring with a connecting rope to prevent the positioning pin 9 from being lost.

[0039] In this embodiment, the surface of the acrylic front panel 113 is provided with a hidden groove that is compatible with the adjustment frame 21. After folding, the adjustment frame 21 of the acrylic top cover 114 can be inserted into the inner cavity of the hidden groove for storage, thus avoiding interference of the adjustment frame 21 with the folding operation.

[0040] In practical use: When it needs to be unfolded into a protective isolation cover, first unfold the acrylic front panel 113, acrylic back panel 112 and acrylic side panels 111 on both sides outwards in sequence until each panel is perpendicular to the mounting base frame 110. At this time, each panel is kept in the unfolded posture by the limiting effect of the hinge 3. Then rotate the acrylic top cover 114 so that the acrylic top cover 114 is stably covered on the top of the acrylic back panel 112 and the acrylic side panels 111 on both sides. Then pull the ring upwards, and the ring moves the adjusting rod 22 upwards, so that the adjusting rod 22 moves upwards through the support hole 8 with the positioning pin 9. Then pull the positioning pin 9 out of the inner cavity of the support hole 8, and then release the ring. The support spring 24 is released and can push the support seat 23 downwards. The support seat 23 moves downwards with the adjusting rod 22. The bottom end of the adjusting rod 22 pushes the positioning seat 5 to move. During the downward movement of the positioning seat 5, the limiting blocks 10 on both sides slide along the adjusting groove 4. Finally, the sliding grooves 11 on both sides of the lower surface of the positioning seat 5 are precisely connected with the slider 12 at the top of the acrylic side plate 111, and the positioning groove 13 on the lower surface is precisely engaged with the positioning block 14 on the surface of the acrylic back plate 112, so as to achieve all-round positioning and fixing of the acrylic side plate 111 and the back plate, and the deployment operation of the protective isolation cover can be completed. When folding, the operator pulls the pull ring upwards, causing the adjusting rod 22 and the support seat 23 on the surface to move upwards. The support seat 23 compresses the support spring 24 at the top, causing it to contract and deform. At the same time, the positioning seat 5 at the bottom of the adjusting rod 22 moves upwards and gradually slides into the inner cavity of the adjusting groove 4 until the positioning seat 5 is in place with the inner wall of the adjusting groove 4. At this time, the positioning seat 5 disengages from the slider 12 of the acrylic side plate 111 and the positioning block 14 of the acrylic back plate 112, releasing the positioning and fixing of each plate. When the adjusting rod 22 moves with the support hole 8 to directly above the adjusting frame 21, the positioning pin 9 is inserted into the inner cavity of the support hole 8. The lower surface of the positioning pin 9 fits tightly with the top of the adjusting frame 21, fixing the position of the adjusting rod 22 and the positioning seat 5, preventing the support spring 24 from resetting and causing the positioning seat 5 to move down, interfering with the folding. Subsequently, the operator folds the acrylic side panels 111 first, then the acrylic back panel 112, and finally the acrylic front panel 113 in sequence. Through the rotation of the built-in hinge 3, each panel is folded until it fits snugly against the mounting base frame 110. Then, the connecting seat 16 is rotated to fold the acrylic top cover 114, thus completing the folding operation of the protective isolation cover. The above scheme facilitates the storage of the protective isolation cover, reduces the space occupied by the protective isolation cover during storage, reduces the space occupied by the storage cover, and improves the convenience of storing the isolation cover.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
