Description

Technical Field

[0001] This utility model relates to the field of connection device technology, specifically a hardware connection device for a collaborative office cloud platform. Background Technology

[0002] With the evolution of modern office models, collaborative office cloud platform hardware, with large touch screens and integrated whiteboards as its core, has become the standard configuration for corporate meeting rooms and open office spaces. These hardware devices are usually large in size and heavy in weight, and their installation and fixing methods are directly related to safety and spatial aesthetics. Especially in modern office environments that widely use glass curtain walls and marble veneers as partitions, traditional installation methods such as drilling and pre-embedded bolts are no longer applicable. This makes it a technical problem that urgently needs to be solved in this field to safely and reliably fix heavy hardware on these smooth and indestructible special surfaces for a long time.

[0003] Currently, using vacuum suction cups is the mainstream technical approach to address this problem, for example:

[0004] Chinese invention patent CN108147127B discloses a glass suction cup device. Its main purpose is to clean the glass surface before the suction cup adsorbs by setting a rotating cylinder and brush bristles, and at the same time use the air discharged by downward pressure to blow away the dust, thereby improving the adsorption force of a single suction cup. This solution aims to improve the initial success rate of single-point adsorption.

[0005] Chinese invention patent CN114012771B discloses an adsorption tool for moving photoelectric glass. The method involves first adsorbing several independent suction cups onto the glass, and then connecting these suction cups together with a bracket to form a whole for transport. This solution, through step-by-step operation, aims to avoid stress warping of the glass sheet caused by simultaneous adsorption by the suction cup array, and is mainly applied to temporary transport scenarios.

[0006] The above design provides a solution for attachment or transport on smooth surfaces using vacuum suction cups. However, it has certain limitations, especially in fixed scenarios such as collaborative office cloud platform hardware that require long-term, heavy-duty, and high-security operation. The shortcomings of existing technologies are mainly reflected in the following: the suction force gradually weakens due to time, temperature changes, and minor vibrations; operators cannot determine whether the adhesion is still firm, posing a serious safety hazard. Once the suction force decreases, the equipment may suddenly fall, causing property damage and personal injury risks. Existing suction cups mostly rely on a single elastomer seal, which is problematic for installation... The surface flatness and cleanliness requirements are extremely high. For surfaces with minor scratches or unevenness, the sealing effect and durability will be greatly reduced, and the reliability of long-term heavy-load fixation cannot be guaranteed. In the existing technology, each suction cup works independently, like scattered soldiers, which cannot guarantee that the force on each suction cup is uniform. Over time, this may cause some suction cups to be overloaded and fail prematurely, or cause stress damage to the equipment itself due to uneven force. The installation process of the existing solution, especially ensuring that multiple suction cups are on the same plane and that the force is uniform, largely depends on the experience and skill of the operator. The process is cumbersome, inefficient, and it is difficult to guarantee the consistency of installation quality.

[0007] Therefore, there is an urgent need for a collaborative office cloud platform hardware connection device that can be securely, reliably, and permanently fixed on special surfaces such as glass, while also providing real-time status monitoring, proactive safety assurance, convenient installation, and enabling multi-point collaborative work, in order to address the many shortcomings of the existing technologies mentioned above. Summary of the Invention

[0008] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a hardware connection device for collaborative office cloud platform to solve the above-mentioned problems.

[0009] The purpose of this utility model is achieved through the following technical solution: a hardware connection device for a collaborative office cloud platform, including a control system and a first suction cup array and a second suction cup array arranged in parallel. An upper load-bearing guide rail and a lower locking guide rail are respectively fixedly connected to the first and second suction cup arrays. Multiple brackets are snapped onto the ends of the upper load-bearing guide rail and the lower locking guide rail away from the first suction cup array. Both the first and second suction cup arrays include multiple suction cups. The suction cups on the first suction cup array are all fixedly connected to the upper load-bearing guide rail, and the suction cups on the second suction cup array are all fixedly connected to the lower locking guide rail. Each suction cup includes a suction cup shell, and a fixing ring is fixedly connected to the end of the suction cup shell away from the bracket. The fixing ring is located away from the suction cup shell. One end of the body is fixedly connected to an outer ring and an inner ring. An adjusting ring is fixedly connected between the outer ring and the inner ring. An upper coil is fixedly connected to the top of the adjusting ring near its outer side, and a lower coil is fixedly connected to the end of the adjusting ring away from the fixed ring. A filling chamber is formed between the fixed ring, the outer ring, and the inner ring. Two-thirds of the volume of the filling chamber is filled with magnetorheological fluid. Multiple adjusting branches are fixedly connected to the top of the fixed ring. The ends of the multiple adjusting branches away from the fixed ring all penetrate the suction cup housing, and the penetration parts are fixedly connected to the main adjusting pipe. A negative pressure bladder is fixedly connected to the end of the suction cup housing near the fixed ring. An adjusting indicator screw is rotatably connected to the top of the negative pressure bladder. The end of the adjusting indicator screw away from the negative pressure bladder penetrates the suction cup housing, and the penetration part is threadedly connected to the adjusting nut.

[0010] The bracket has multiple fixing holes for fixing the office cloud platform. The suction cup housing is fixedly connected to the corresponding upper load-bearing guide rail and lower locking guide rail, and the inner ring is located inside the outer ring.

[0011] The adjusting ring is made of soft magnetic material. In its free state, the end face of the adjusting ring away from the fixed ring extends 1-2 mm beyond the end faces of the outer ring and the inner ring away from the fixed ring. The ends of the outer ring and the adjusting ring that are away from the fixed ring and close to each other are both provided with bevels.

[0012] Both the outer ring and the inner ring are hollow near the fixed ring, and the fixed ring is also hollow near the outer ring. The hollow parts of the fixed ring, the outer ring, and the inner ring are interconnected.

[0013] The regulating ring and the upper coil are electrically connected to the control system. The outer ring and the inner ring are both provided with micropores near the lower coil to allow the magnetorheological fluid to flow. The regulating branch pipe is a flexible hose.

[0014] The adjusting branch pipe is bent between the fixed ring and the adjusting ring. A sealed bellows is fixedly connected between the top of the negative pressure bladder and the suction cup housing. The suction cup housing is slidably connected to the outer end of the adjusting indicator screw.

[0015] Multiple suction cup housings are fixedly connected to the top of the suction cup housings. A negative pressure chamber is formed between the suction cup housings and the negative pressure bladder. The negative pressure tubes are connected to the negative pressure chambers. The ends of the multiple negative pressure tubes that are away from the suction cup housings converge together and are interconnected. The ends of the multiple negative pressure tubes that are interconnected are connected to an external negative pressure system through pipes. The external negative pressure system is electrically connected to the control system.

[0016] Multiple regulating main pipes are interconnected by pipes, and one end of each pipe is connected to an external negative pressure system. The outer ring, inner ring, negative pressure bladder, and sealing bellows are all made of flexible materials.

[0017] The adjusting ring has through holes at positions corresponding to the adjusting branch pipe, and the end of the through hole away from the adjusting branch pipe passes through the adjusting ring. The bottom of the suction cup housing has a groove, and the top of the fixing ring is fixedly connected to the top of the groove of the suction cup housing. The top of the suction cup housing has rounded corners, and the top of the sealing bellows is fixedly connected to the top of the groove of the suction cup housing. Both the outer ring and the inner ring are made of platinum vulcanized silicone.

[0018] The beneficial effects of this utility model are:

[0019] 1. The vacuum pressure-sensitive anchoring technology used in this solution allows for secure installation on smooth surfaces such as glass and marble, where drilling is prohibited or inconvenient, without damaging the wall structure. This frees the deployment of high-end conference equipment from the constraints of traditional load-bearing walls, enabling better integration into modern office space designs and more flexible layouts. Furthermore, the device features both automated and manual operation modes. In well-equipped smart conference rooms, efficient and unified automated installation can be achieved through an external system. In temporary settings where power or external air supply is limited, its fully manual mechanical operation mode can independently complete all fixing work, ensuring the device's versatility and reliability under different conditions.

[0020] 2. To ensure the safety of the expensive equipment, this solution establishes a multi-dimensional protection mechanism. First, in terms of sealing design, it forms a reliable double-sealing structure through the physical bonding of flexible materials and the active filling and curing of magnetorheological fluid. This not only improves the success rate of initial installation but also effectively resists the risk of leakage caused by minor vibrations or temperature changes, enhancing the stability of long-term adsorption. Second, an intuitive physical state indication mechanism is designed. Through an indicator screw directly linked to the internal negative pressure, operators can clearly and accurately judge the current adsorption force state simply by visually observing its extension length. This purely mechanical indication method avoids the potential failure risk of electronic sensors, providing a reliable basis for safety judgment. Combined with a manual locking nut, the adsorption state can be mechanically locked a second time, further enhancing safety. Finally, in the multi-suction cup collaborative working mode, the internal pipeline system helps to balance the negative pressure of each suction cup, preventing the stability of the entire array from decreasing due to slight leakage of a single suction cup, and improving the overall fault tolerance of the system.

[0021] 3. This solution transforms complex professional installation work into a simpler and more efficient operating process. The auxiliary tools integrated into the device itself, such as the level built into the guide rail and the optical guide system for vertical alignment, effectively reduce the reliance on the professional skills of the operators and auxiliary tools during installation, making the whole process simpler and more precise. In automated mode, the complex vacuuming, locking, and monitoring steps are integrated into the control system, enabling "one-click" rapid deployment, which significantly shortens the on-site installation and commissioning time. At the same time, since the entire process is non-destructive installation, the wall surface can be kept intact during disassembly or relocation, making it particularly suitable for rental properties or office spaces with high-standard decoration requirements.

[0022] 4. By integrating with the control system, this device is no longer an isolated piece of hardware, but rather a device that can be incorporated into an intelligent management system. This makes it possible to remotely monitor the working status of the mounting bracket and receive early warnings of abnormal vibrations or pressure changes, facilitating timely preventative maintenance by management personnel and thus better protecting equipment assets. At the same time, the coordinated control of the entire suction cup array can ensure that the supporting force applied to large equipment is evenly distributed, avoiding stress concentration problems caused by installation errors or long-term use, and helping to protect the hardware itself from damage.

[0037] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0038] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0039] Example 1

[0040] like Figures 1 to 12 As shown, this embodiment provides a hardware connection device for a collaborative office cloud platform. Its overall structure includes a control system and a first suction cup array and a second suction cup array arranged in parallel. The first suction cup array and the second suction cup array are respectively fixedly connected to each other with an upper load-bearing guide rail 1 and a lower locking guide rail 2. Multiple brackets for supporting the collaborative office cloud platform host are installed on the upper load-bearing guide rail 1 and the lower locking guide rail 2 by snap-fit. Furthermore, multiple fixing holes are opened on the brackets for firmly installing the office cloud platform host on them with fasteners such as bolts.

[0041] Both the first and second suction cup arrays consist of multiple suction cups with the same structure. The following section will take a single suction cup as an example to explain its specific structure in detail.

[0042] Each suction cup includes a suction cup housing 3 as the main frame. One end of the suction cup housing 3 is fixedly connected to the corresponding upper load-bearing guide rail 1 or lower locking guide rail 2 to ensure the overall rigidity of the device. At the bottom of the suction cup housing 3, a groove is provided to facilitate installation and protect the internal structure.

[0043] At the end of the suction cup housing 3 away from the support, that is, the end facing the surface to be adsorbed (such as a glass wall), a precision sealing assembly is provided. Specifically, a fixing ring 4 serving as a base is fixedly connected to the top of the groove of the suction cup housing 3. At the end of the fixing ring 4 away from the suction cup housing 3, an outer ring 5 and an inner ring 6 are further fixedly connected, with the inner ring 6 located inside the outer ring 5. Both the outer ring 5 and the inner ring 6 are made of platinum vulcanized silicone material with excellent elasticity and sealing performance.

[0044] Between the outer ring 5 and the inner ring 6, there is a fixedly connected adjusting ring 7, which serves as the core driving component. The adjusting ring 7 is made of soft magnetic material to facilitate subsequent electromagnetic control. Structurally, in order to achieve initial positioning and sealing, the end face of the adjusting ring 7 away from the fixed ring 4 in its free state will extend 1-2 mm beyond the end faces of the outer ring 5 and the inner ring 6. In order to achieve good mechanical guidance under pressure, both the outer ring 5 and the adjusting ring 7 have bevels on the side away from the fixed ring 4 and close to each other.

[0045] To accommodate and control the functional liquid, the internal structures of the fixed ring 4, outer ring 5, and inner ring 6 are designed to be hollow, and these hollow parts are interconnected to form a closed filling chamber. Approximately two-thirds of the volume of the filling chamber is pre-filled with magnetorheological fluid, which can change its viscosity under the action of a magnetic field. To achieve control of the magnetorheological fluid, an upper coil 8 is fixed at the top of the adjusting ring 7 near its outer side, and a lower coil 9 is fixed at the end of the adjusting ring 7 away from the fixed ring 4. Both the upper coil 8 and the lower coil 9 are electrically connected to the control system. To allow the magnetorheological fluid to flow out as needed to enhance the seal, micropores are provided at the ends of the outer ring 5 and inner ring 6 near the lower coil 9.

[0046] In order to replenish or balance the pressure of the magnetorheological fluid, a number of regulating branches 10, which are flexible hoses, are fixedly connected to the top of the fixed ring 4. The ends of the multiple regulating branches 10 away from the fixed ring 4 all penetrate the suction cup housing 3 and are connected to a regulating main pipe 11. A through hole is provided on the regulating ring 7 at the corresponding position of the regulating branch 10, and the through hole penetrates the regulating ring 7.

[0047] Inside the suction cup housing 3, there is a manual negative pressure generation and status indication mechanism. Specifically, a deformable negative pressure bladder 12 is fixedly connected to one end of the suction cup housing 3 near the fixing ring 4. The top of the negative pressure bladder 12 is rotatably connected to the end of the adjusting indicator screw 13. The rod of the adjusting indicator screw 13 passes through the top of the suction cup housing 3, and its through part is connected to an adjusting nut by a threaded engagement. In order to ensure that the airtightness inside the suction cup housing 3 is not compromised when the adjusting indicator screw 13 moves, a sealing bellows 14 is fixedly connected between the top of the negative pressure bladder 12 and the suction cup housing 3. The top of the sealing bellows 14 is fixedly connected to the top of the groove of the suction cup housing 3. Its structure can freely expand and contract with the reciprocating movement of the adjusting indicator screw 13, thereby ensuring that the suction cup housing 3 and the outer end of the adjusting indicator screw 13 always maintain a sliding connection and airtight seal.

[0048] Work process

[0049] First, fix the upper load-bearing guide rail 1 and the lower locking guide rail 2 onto the first and second suction cup arrays respectively, and then attach the bracket to the guide rail. The operator holds the entire device and places it against a flat surface such as a glass wall to be fixed. Since the end face of the adjusting ring 7 extends beyond the outer ring 5 and the inner ring 6, the adjusting ring 7 will first contact the wall surface, thus playing a preliminary positioning role.

[0050] The operator applies pressure to the suction cup housing 3 in a direction perpendicular to the wall. Under this pressure, the protruding adjustment ring 7 will move backward, and the bevel of its side will interact with the bevel of the outer ring 5, guiding the outer ring 5 and inner ring 6, made of platinum vulcanized silicone, to undergo uniform elastic deformation. Their lips will fit tightly against the wall, thus forming a reliable initial physical seal.

[0051] In scenarios requiring extreme sealing, the control system can supply current to the lower coil 9, and the generated magnetic field drives the magnetorheological fluid in the filling chamber to seep out through the micropores on the outer ring 5 and inner ring 6, filling and sealing any microscopic gaps that may exist between the physical contact surfaces, forming a second seal.

[0052] The operator manually rotates the adjusting nut located outside the suction cup housing 3 clockwise. Due to the threaded connection, the adjusting nut will drive the adjusting indicator screw 13 to move away from the wall. The adjusting indicator screw 13 will then pull the negative pressure bladder 12 connected to it, increasing the volume of the negative pressure bladder 12. This will cause negative pressure to be generated in the negative pressure chamber formed by the sealed bellows 14 and the negative pressure bladder 12. Under the action of the external atmospheric pressure, the entire suction cup is pressed against the wall by a strong and uniform force, achieving firm adsorption.

[0053] During the above process, as the negative pressure increases, the length of the adjusting indicator screw 13 extending outside the suction cup housing 3 will become longer and longer. The operator can visually or touch this extension length to intuitively and accurately judge the current suction cup's adhesion strength, thus achieving physical safety redundancy. When the required adhesion force is reached, the thread friction of the adjusting nut itself can play a locking role, enabling the device to maintain a negative pressure state for a long time.

[0054] When the device needs to be removed, the operator rotates the adjusting nut counterclockwise to move the adjusting indicator screw 13 toward the wall, thereby eliminating the tension of the negative pressure bladder 12, balancing the pressure inside the negative pressure chamber with the outside, and the adsorption force disappears. If the magnetorheological fluid seal is activated, the current to the lower coil 9 is cut off first, and the upper coil 8 can be briefly energized to help the magnetorheological fluid flow back. After that, the entire device can be easily removed.

[0055] By combining a flexible physical seal consisting of an adjusting ring 7, an outer ring 5, and an inner ring 6 with a magnetorheological fluid seal that can be activated on demand, dual protection is achieved, ensuring the airtightness and adsorption reliability of the device under various surface conditions.

[0056] The fully manual negative pressure generating mechanism, consisting of the adjusting indicator screw 13, the adjusting nut, and the negative pressure bladder 12, enables the device to be firmly installed and fixed even in harsh environments without external power or air supply, greatly expanding its application scenarios.

[0057] The extension length of the adjusting indicator screw 13 is directly related to the adsorption force, providing operators with a simple, intuitive, and absolutely reliable physical state indicator, avoiding safety hazards caused by electronic sensor failure, and achieving inherent safety.

[0058] By adding a sealed bellows 14, the overall airtightness of the system is ensured to be maintained during long-term reciprocating motion of the core moving component, the adjusting indicator screw 13, which significantly improves the durability and service life of the product. At the same time, high-performance materials such as platinum vulcanized silicone are selected to ensure the anti-aging and durability of key components such as the outer ring 5 and the inner ring 6.

[0059] Example 2

[0060] like Figures 1 to 12 As shown, the technical solution of this embodiment is a further improvement and functional expansion based on all the structural and technical features disclosed in Embodiment 1. Therefore, for the structural parts that are the same as those in Embodiment 1, this embodiment will not repeat them. Their specific structure, connection relationship and basic functions can be referred to the description of Embodiment 1. The focus of this embodiment is to explain in detail its newly added structure and the new automated and networked working mode it brings.

[0061] As an improvement to Embodiment 1, this embodiment adds an external negative pressure system and a matching pipeline structure to the overall structure of the device, aiming to achieve centralized, automatic and coordinated control of all suction cups.

[0062] Specifically, at the top of each suction cup housing 3 in the first and second suction cup arrays, a negative pressure tube 15 is fixedly connected in an airtight manner. Inside each suction cup, the space enclosed by the suction cup housing 3 and the negative pressure bladder 12 forms a negative pressure chamber, and one end of the negative pressure tube 15 is connected to this negative pressure chamber. In the overall layout of the device, multiple negative pressure tubes 15 from all suction cups converge and are interconnected at the ends away from the suction cup housing 3 through pipe fittings such as T-joints, forming a unified main negative pressure network. The end of this main negative pressure network is connected to an external negative pressure system through a pipe. The external negative pressure system, for example, can be an electrically controlled vacuum pump, which is electrically connected to the control system of this device to receive commands and perform pumping or replenishing operations.

[0063] Furthermore, this embodiment also upgrades the pipeline system composed of the regulating main pipe 11 to a network. Specifically, the regulating main pipes 11 from each suction cup are also interconnected through pipes to form a unified auxiliary pipeline network. Similar to the main negative pressure pipeline network, the end of this interconnected auxiliary pipeline network is also connected to the same external negative pressure system through pipes. Through this structure, the external negative pressure system can control the gas in different areas inside the suction cup in a step-by-step and precise manner through two independent pipeline paths.

[0064] In addition, to ensure the deformation capacity and sealing performance of the device in both automated and manual modes, this embodiment specifies that the outer ring 5, inner ring 6, negative pressure bladder 12, and sealing bellows 14 are all made of flexible materials, which provides the necessary structural basis for complex pressure changes and mechanical movements.

[0065] Work process

[0066] After introducing an external negative pressure system, the main working process of this embodiment is a highly efficient automated adsorption mode, while retaining the manual mode of Embodiment 1 as an emergency backup. The specific automated working process is as follows:

[0067] Initial positioning and physical sealing are the same steps as in Example 1. The operator places the device against the wall and manually presses the adjusting ring 7 to cause elastic deformation of the outer ring 5 and the inner ring 6, thereby forming a preliminary physical seal with the wall.

[0068] The magnetorheological fluid sealing is enhanced, and this step is the same as in Example 1. The control system can energize the lower coil 9 as needed to drive the magnetorheological fluid to seep out to complete the second sealing.

[0069] After the physical seal is completed, the control system issues the first command to start the external negative pressure system. At this time, the external negative pressure system evacuates air through the auxiliary pipeline network connected to multiple regulating main pipes 11. The gas is drawn out through the through hole on the regulating ring 7 and the regulating branch pipe 10. The purpose of this is to quickly form a preliminary negative pressure environment in the area near the sealing ring surrounded by the outer ring 5 and the inner ring 6. This negative pressure will make the flexible outer ring 5 and inner ring 6 fit more tightly against the wall, thereby greatly enhancing the reliability of the initial seal.

[0070] Immediately afterwards, the control system issued a second command, and the external negative pressure system continued to work, and evacuated air through the main negative pressure pipeline network connected to multiple negative pressure pipes 15. Since the negative pressure pipes 15 are directly connected to the main negative pressure chamber inside the suction cup, this action will quickly remove most of the air in the negative pressure chamber, so that the negative pressure bladder 12 is quickly compressed under the action of external atmospheric pressure. The movement of the negative pressure bladder 12 generates a strong suction force, which firmly adsorbs the entire suction cup shell 3 and the entire device onto the wall, completing the final adsorption and fixation.

[0071] During this automation process, the adjusting indicator screw 13 will continue to extend outward as the negative pressure bladder 12 moves, serving as a real-time physical status indicator. An important additional operation is that after the automated adsorption is completed, the operator can manually turn the adjusting nut to mechanically lock the adjusting indicator screw 13 at its current longest extended position. This not only serves as a safety measure to prevent accidents, but also allows the external negative pressure system to be shut off after locking, relying on the suction cup's own airtightness and mechanical locking to maintain the adsorption force for a long time, thus saving energy.

[0072] If the external negative pressure system fails to work for any reason, this embodiment can seamlessly switch to the pure manual mode of Embodiment 1. The operator can directly drive the adjustment indicator screw 13 and the negative pressure bladder 12 to generate suction force by rotating the adjustment nut, ensuring the availability of the device under any circumstances.

[0073] When the device needs to be removed, the control system sends a command to the external negative pressure system to stop pumping air and refill the two pipelines with air to quickly balance the internal and external pressure difference. At the same time, the current of the upper coil 8 and the lower coil 9 is controlled to allow the magnetorheological fluid to flow back, after which the device can be easily removed.

[0074] In use, fix the upper load-bearing guide rail 1 to the first suction cup array, fix the lower locking guide rail 2 to the second suction cup array, then attach multiple brackets to the upper load-bearing guide rail 1 and the lower locking guide rail 2, then attach the first suction cup array and the second suction cup array to the surface to be fixed, such as a glass partition, and then install the office cloud platform onto the brackets.

[0075] When it is necessary to attach the suction cup to the fixed surface, first, make the adjusting ring 7 contact with the fixed surface, and then manually push the suction cup housing 3 to apply pressure in the direction perpendicular to the fixed surface. At this time, the adjusting ring 7 moves towards the fixed ring 4 under the action of pressure. The adjusting ring 7 also drives the outer ring 5 and the inner ring 6 away from the fixed ring 4 to move towards each other. As the adjusting ring 7 moves towards the fixed ring 4, the outer ring 5 and the inner ring 6 then come into contact with the fixed surface. Then continue to apply pressure until the outer ring 5 and the inner ring 6 press against the fixed surface.

[0076] Then, current is passed into the lower coil 9. At this time, the magnetorheological fluid flows through the micropores on the outer ring 5 and inner ring 6 under the action of magnetic force to the bottom of the regulating ring 7 and gathers at the bottom of the regulating ring 7. The magnetorheological fluid then seals the regulating ring 7 and the fixed surface.

[0077] Then, through the external negative pressure system, some of the gas between the fixed surface and the outer ring 5 and inner ring 6 is extracted via the regulating branch pipe 10 and the regulating main pipe 11. Since the regulating ring 7 has a through hole, under the action of negative pressure, the outer ring 5 and inner ring 6 adsorb the fixed surface, thereby initially fixing the suction cup housing 3 on the fixed surface and achieving a good seal.

[0078] Then, the gas in the negative pressure chamber is extracted by the external negative pressure system. At this time, the bottom of the negative pressure bladder 12 moves towards the suction cup housing 3, so that the suction cup housing 3 is more firmly adsorbed onto the fixing surface, and the final adsorption and fixation are achieved.

[0079] During this process, the adjusting screw 13 moves closer to the suction cup housing 3. The degree of adsorption can be judged by adjusting the distance of the adjusting screw 13 extending out of the suction cup housing 3. The more the suction cup housing 3 extends out, the stronger the adsorption force. If gas enters between the outer ring 5, inner ring 6 and adjusting ring 7 during use, causing the suction cup adsorption force to decrease, the suction cup housing 3 will gradually reduce the extension amount, and thus it can be judged that the suction cup adsorption force has decreased.

[0080] When the device needs to be removed after use, first remove the negative pressure between the suction cup housing 3 and the negative pressure bladder 12, then pass current through the upper coil 8, and then cut off the current on the lower coil 9. At this time, the magnetorheological fluid flows back into the outer ring 5 and inner ring 6 under the action of the magnetic force of the upper coil 8. Then remove the negative pressure between the outer ring 5, inner ring 6 and the fixed surface, and the device can be removed.

[0081] During use, after the suction cup is fixed to the fixed surface, the adjusting nut can be manually turned to lock the adjusting indicator screw 13. At this time, the external negative pressure system can be turned off, and the suction cup can be firmly attached to the fixed surface.

[0082] When in use, if the external negative pressure system cannot work effectively, the adjusting nut can be turned manually to make the adjusting indicator screw 13 drive the negative pressure bladder 12 to move closer to the suction cup housing 3, thereby making the suction cup adhere to the fixed surface.

[0083] By linking the control system with the external negative pressure system, the entire suction cup array can be quickly adsorbed and released with a single click, which greatly simplifies the installation process, improves installation efficiency and operational consistency, and is particularly suitable for scenarios that require rapid deployment or frequent relocation.

[0084] By connecting the negative pressure tubes 15 and regulating main tubes 11 of all suction cups to the network, it is ensured that the negative pressure value applied to each suction cup by the external negative pressure system is equal and synchronized. This is crucial for supporting large and heavy collaborative office cloud platform hardware and can effectively avoid stress concentration and safety hazards caused by uneven adsorption forces at various points.

[0085] An innovative two-stage negative pressure adsorption process was designed. First, the sealing ring was pre-tightened by adjusting the main pipe 11, and then the main cavity was evacuated by the negative pressure pipe 15. This step-by-step pressurization method makes the process more stable and the control more precise, further improving the success rate and reliability of the adsorption process.

[0086] This embodiment perfectly combines the high efficiency of automation with the reliability of manual operation. Operators can enjoy the convenience brought by the external system, and in any unexpected situation, they can rely on the solid manual backup consisting of the adjusting indicator screw 13 and the adjusting nut. This dual redundancy design makes the safety and reliability of this device reach a new level, which is sufficient to meet various critical mission occasions.
