Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and more specifically to a retractable reflector-assisted 5G antenna structure. Background Technology

[0002] Smart metasurfaces, also known as reconfigurable smart surfaces or smart reflective surfaces, or simply dynamic RIS, can be used as reflectors to assist 5G antennas. By adjusting the absorption, reflection, refraction, and phase of passive reflective elements in real time, smart metasurfaces can flexibly guide incident electromagnetic signals to the desired direction, optimize the propagation path of wireless signals, and thus significantly improve signal quality, coverage, and system performance.

[0003] To address this, this application designs a retractable reflector-assisted 5G antenna structure. Most existing dynamic RIS (Radio Resonance Array) systems employ an open, unprotected structure. While this design offers advantages such as low cost, flexible deployment, and good heat dissipation, it suffers from some significant drawbacks when deployed outdoors.

[0004] Due to the high R&D and production costs of dynamic RIS, and their mostly thin and light structure, most dynamic RIS are directly deployed using mounting brackets, which raises concerns about installation stability. In addition, to reduce external influences, dynamic RIS typically need to be installed in relatively mild environments, limiting their application in complex environments. Furthermore, after severe weather warnings are issued, staff need to take protective measures to prevent performance degradation or equipment damage. If weather conditions are too severe, the equipment may even need to be temporarily retrieved or shut down until the weather improves. This necessitates frequent inspections and repairs, increasing long-term maintenance costs. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a retractable reflector-assisted 5G antenna structure. This effectively solves the problems of existing technologies, which mostly rely on direct deployment using mounting brackets, resulting in less stable installation. Furthermore, dynamic RIS (Radio Reflector Assisted Antenna) systems typically require installation in relatively mild environments, limiting their application in complex environments. Additionally, after severe weather warnings are issued, protective measures must be taken to prevent performance degradation or equipment damage. In extremely severe weather conditions, the equipment may even need to be temporarily recalled or shut down until the weather improves, requiring frequent inspections and repairs, thus increasing long-term maintenance costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a retractable reflector-assisted 5G antenna structure, comprising:

[0008] The mounting bracket is used to adjust the installation height. A protective box is installed on the mounting bracket. The dynamic RIS body is slidably installed on the upper end of the protective box through the clearance sliding hole. The dynamic RIS body consists of a reflective panel and a back plate. A support slide is slidably installed inside the protective box. The protective box and the support slide are both provided with a telescopic support part. The dynamic RIS body and the support slide are both provided with a snap-fit ​​part.

[0009] The telescopic support includes a lead screw that is rotatably installed at the bottom of the protective box through a circular mounting hole. The upper end of the lead screw is threaded to the support slide, and a handwheel is installed at the lower end of the lead screw. A triangular support group is jointly provided on the protective box and the support slide.

[0010] The locking part includes circular grooves symmetrically opened on the upper end of the support slide, and abutment slide rods symmetrically installed on the upper inner wall of the protective box. The outer walls of the two abutment slide rods are respectively movably attached to the inner walls of the corresponding circular grooves. Locking assemblies are provided on the support slide at the positions corresponding to the two circular grooves on the left and right.

[0011] Furthermore, the triangular support assembly includes rectangular clearance holes at both the front and rear ends of the protective box. Support rods are rotatably mounted on the lower inner walls of the left and right ends of the multiple rectangular clearance holes. Incomplete gears are fixedly sleeved on the outer walls of the support rods. Rectangular mounting holes are opened at the upper end of the support slide corresponding to the positions of the multiple incomplete gears. Racks are installed in the rectangular mounting holes.

[0012] Furthermore, the triangular support assembly also includes a support bracket installed on the outer wall of the incomplete gear at the tooth notch. Magnets are embedded at both ends of the support bracket on the side away from the incomplete gear, and magnets are also embedded on the upper inner walls of both ends of the rectangular clearance hole.

[0013] Furthermore, the snap-fit ​​assembly includes snap-fit ​​rods installed on the lower end of the dynamic RIS body reflective panel and the back plate. The upper end of the support slide has two rectangular slots corresponding to the positions of the front and rear snap-fit ​​rods. The outer walls of the front and rear snap-fit ​​rods are respectively movably attached to the inner walls of the corresponding rectangular slots. The inner wall of the rectangular slot facing the shorter outer wall of the support slide has a receiving groove. The inner wall of the receiving groove facing the shorter outer wall of the support slide is slidably connected to a wedge-shaped snap-fit ​​plate by a compression spring. The wedge-shaped snap-fit ​​plate movably abuts against the corresponding snap-fit ​​rod.

[0014] Furthermore, the snap-fit ​​assembly also includes a rectangular connecting groove that is opened between the front and rear receiving slides. A wedge-shaped abutment plate is slidably installed in the rectangular connecting groove, and the front and rear ends of the wedge-shaped abutment plate are respectively fixedly connected to the corresponding wedge-shaped snap-fit ​​plate.

[0015] Furthermore, a mounting plate is installed on the upper end of the mounting bracket, and a mounting groove is opened at the front end of the mounting plate. A U-shaped sliding plate is slidably connected in the mounting groove through a compression spring. An avoidance sliding hole is also opened at the upper end of the U-shaped sliding plate corresponding to the position of the dynamic RIS body. The outer wall of the dynamic RIS body is movably attached to the inner wall of the avoidance sliding hole on the U-shaped sliding plate, and a triangular inclined groove connected to the avoidance sliding hole is opened at the lower end of the U-shaped sliding plate.

[0016] Furthermore, the front end of the convex-shaped slide plate is provided with a rectangular connecting hole that connects to the avoidance sliding hole. Cleaning horizontal plates are installed on the inner walls of the left and right ends of the rectangular connecting hole. The rear end of the cleaning horizontal plate is movably attached to the reflective panel of the dynamic RIS body.

[0017] Furthermore, the reflective panel of the dynamic RIS body is equipped with filler plates at both the top and bottom, and multiple drainage holes are provided at the bottom of the protective box.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] This invention presents a retractable reflector-assisted 5G antenna structure. Utilizing a retractable dynamic RIS (Radio Reflector Integrated System) body, it avoids the problem of damage to the reflector panel of the dynamic RIS body during transportation and installation. By rotating a handwheel, the support slide moves multiple racks upwards synchronously. Each corresponding rack engages with a corresponding incomplete gear, causing multiple incomplete gears to rotate around their respective support rods. These incomplete gears then drive their corresponding support legs to rotate synchronously until the side of the support legs furthest from the incomplete gears is flush with the installation ground. This achieves the effect of multiple support legs strengthening the installation stability of the dynamic RIS body through triangular support, enabling installation and deployment in complex environments and effectively enhancing the deployment range of the dynamic RIS.

[0020] When a severe weather warning is issued, to prevent performance degradation or equipment damage to the dynamic RIS, the operator rotates the handwheel in reverse. The lead screw drives the dynamic RIS body downwards via the support slide. Through rack and pinion and incomplete gear transmission, multiple incomplete gears rotate in the opposite direction around their corresponding support rods. These incomplete gears then drive their corresponding support legs to rotate synchronously in the opposite direction until the side of the support legs furthest from the incomplete gears rotates into their corresponding rectangular clearance holes. At this point, the protective box becomes closed, thus providing physical protection for the dynamic RIS body. Even in extremely severe weather conditions, there is no need for the operator to temporarily retrieve or stop the equipment, reducing frequent inspections and repairs of the dynamic RIS body and lowering long-term maintenance costs.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to embodiments.

[0036] Example:

[0037] Please see Figures 1-11 This invention provides a technical solution: a retractable reflector-assisted 5G antenna structure, comprising:

[0038] The mounting bracket 1 is used to adjust the installation height. A protective box 2 is installed on the mounting bracket 1. A dynamic RIS body 3 is slidably installed on the upper end of the protective box 2 through a clearance sliding hole. The dynamic RIS body 3 consists of a reflective panel and a back plate. A support slide 4 is slidably installed inside the protective box 2. A telescopic support part 5 is provided on both the protective box 2 and the support slide 4. A snap-fit ​​part 6 is provided on both the dynamic RIS body 3 and the support slide 4.

[0039] The telescopic support part 5 includes a lead screw 51 that is rotatably installed at the bottom of the protective box 2 through a circular mounting hole. The upper end of the lead screw 51 is threaded to the support slide 4, and a handwheel 52 is installed at the lower end of the lead screw 51. A triangular support group 53 is jointly provided on the protective box 2 and the support slide 4.

[0040] The locking part 6 includes circular grooves symmetrically opened on the upper end of the support slide 4. The upper inner wall of the protective box 2 is symmetrically equipped with abutting slide rods 61. The outer walls of the two abutting slide rods 61 are respectively movably attached to the inner walls of the corresponding circular grooves. The support slide 4 is provided with locking groups 62 at the positions corresponding to the two circular grooves on the left and right.

[0041] The triangular support assembly 53 includes rectangular clearance holes at both the front and rear ends of the protective box 2. Support rods 531 are rotatably installed on the lower inner walls of the left and right ends of the multiple rectangular clearance holes. Incomplete gears 532 are fixedly sleeved on the outer wall of the support rods 531. Rectangular mounting holes are opened at the upper end of the support slide 4 corresponding to the positions of the multiple incomplete gears 532. Racks 535 are installed in the rectangular mounting holes.

[0042] The triangular support assembly 53 also includes a support bracket 533 installed on the outer wall of the incomplete gear 532 at the tooth notch. Magnets 534 are embedded at both ends of the side of the support bracket 533 away from the incomplete gear 532. Magnets 534 are also embedded on the upper side of the inner wall of both ends of the rectangular clearance hole.

[0043] The snap-fit ​​assembly 62 includes snap-fit ​​rods 621 mounted on the lower end of the reflective panel and backplate of the dynamic RIS body 3. The upper end of the support slide 4 has two rectangular slots corresponding to the positions of the front and rear snap-fit ​​rods 621. The outer walls of the front and rear snap-fit ​​rods 621 are respectively movably attached to the inner walls of the corresponding rectangular slots. The inner wall of the rectangular slot facing the shorter outer wall of the support slide 4 has a receiving groove. The inner wall of the receiving groove facing the shorter outer wall of the support slide 4 is slidably connected to a wedge-shaped snap-fit ​​plate 622 by a compression spring. The wedge-shaped snap-fit ​​plate 622 movably abuts against the corresponding snap-fit ​​rod 621.

[0044] The snap-fit ​​assembly 62 also includes a rectangular connecting groove that is opened between the front and rear receiving slides. A wedge-shaped abutment plate 623 is slidably installed in the rectangular connecting groove. The front and rear ends of the wedge-shaped abutment plate 623 are respectively fixedly connected to the corresponding wedge-shaped snap-fit ​​plate 622.

[0045] Mounting bracket 1 has a mounting plate 11 installed on its upper end. The front end of mounting plate 11 has a mounting groove. A U-shaped sliding plate 12 is slidably connected in the mounting groove by a compression spring. The upper end of the U-shaped sliding plate 12 has an avoidance sliding hole corresponding to the position of the dynamic RIS body 3. The outer wall of the dynamic RIS body 3 is movably attached to the inner wall of the avoidance sliding hole on the U-shaped sliding plate 12. The lower end of the U-shaped sliding plate 12 has a triangular inclined groove that connects to the avoidance sliding hole.

[0046] The front end of the U-shaped sliding plate 12 is provided with a rectangular connecting hole that connects to the avoidance sliding hole. Cleaning horizontal plate 13 is installed on the inner walls of the left and right ends of the rectangular connecting hole. The rear end of the cleaning horizontal plate 13 is movably attached to the reflective panel of the dynamic RIS body 3.

[0047] The reflective panel of the dynamic RIS body 3 is fitted with filler plates 7 at both the top and bottom, and the bottom of the protective box 2 has multiple drainage holes.

[0048] In practice:

[0049] First, select a suitable installation location based on the target signal coverage area to ensure that the dynamic RIS body 3 can effectively reflect the signal and avoid the installation location being blocked by large obstacles. Then, after fixing the mounting bracket 1 in the appropriate position, adjust the protective box 2 and the mounting bracket 1 to the appropriate height and connect them. Then, perform equipment inspection. It should be noted that the dynamic RIS body 3 is initially in the retracted state inside the protective box 2. At this time, the upper surface of the dynamic RIS body 3 is flush with the upper surface of the protective box 2, and under the action of the compression spring, the convex sliding plate 12 will initially extend out of the mounting sleeve 11, thereby achieving the effect of physical protection for the dynamic RIS body 3. Using a retractable dynamic RIS body 3 can also avoid the problem of the reflective panel of the dynamic RIS body 3 being easily damaged during transportation and installation.

[0050] When it is necessary to control the extension of the dynamic RIS body 3 to adjust the wireless channel, it should be noted that the dynamic RIS body 3 is initially snapped onto the support slide 4 via the snap-fit ​​assembly 62. At this time, multiple snap-fit ​​rods 621 are inserted into their corresponding rectangular slots, and multiple wedge-shaped snap-fit ​​plates 622 are tightly fitted against the side wall of the corresponding end of the snap-fit ​​rod 621 under the compression spring, limiting and tightening it. First, the installer manually rotates the handwheel 52, which drives the lead screw 51 to rotate synchronously. The lead screw 51 drives the support slide 4 to move upward through the threaded transmission. The support slide 4 drives the dynamic RIS body 3 to move upward. During this process, the upper end of the dynamic RIS body 3 will press against the inner wall of the triangular inclined groove on the lower end face of the U-shaped slide plate 12, causing it to move backward and retract into the mounting sleeve 11. This allows the dynamic RIS body 3 to smoothly move upward along the inner wall of the avoidance sliding hole on the convex sliding plate 12 and extend out of the protective box 2 until the working end face of the reflective panel of the dynamic RIS body 3 is completely located on the upper side of the protective box 2. At this time, the lower ends of the two left and right abutment sliding rods 61 will be inserted into the corresponding circular sliding grooves and located on the upper side of the corresponding snap-fit ​​group 62. It should be noted that the cleaning end face of the cleaning horizontal plate 13 is a cleaning soft cloth to avoid damaging the surface of the reflective panel of the dynamic RIS body 3. When the convex sliding plate 12 moves backward and retracts into the mounting sleeve 11, the cleaning horizontal plate 13 will be in contact with the reflective panel of the dynamic RIS body 3. As the dynamic RIS body 3 continues to move upward, the cleaning horizontal plate 13 will clean the reflective panel of the dynamic RIS body 3.

[0051] Simultaneously, as the lead screw 51 drives the support slide 4 upward via threaded transmission, the support slide 4 drives multiple racks 535 to move upward synchronously. It should be noted that the multiple support legs 533 are initially located within corresponding rectangular clearance holes, and the magnets 534 on the multiple support legs 533 are initially magnetically attracted to the magnets 534 embedded in the rectangular clearance holes. When the multiple racks 535 move upward synchronously and pass through the corresponding incomplete gears 532, each corresponding rack 535 will mesh with the corresponding incomplete gear 532. Through the transmission between the racks 535 and the incomplete gears 532, the multiple incomplete gears 532 will drive the multiple incomplete gears 532 to rotate around the corresponding support rod 531. The multiple incomplete gears 532 will then drive the corresponding... The support legs 533 rotate synchronously until the side of the multiple support legs 533 away from the incomplete gear 532 is flush with the installation ground. This achieves the effect of strengthening the installation stability of the dynamic RIS body 3 through triangular support by multiple support legs 533, which can be installed and deployed in more complex environments, effectively increasing the deployment range of the dynamic RIS. In addition, since the dynamic RIS body 3 extends out of the protective box 2, the force-bearing area increases in windy environments. The additional support by multiple support legs 533 can effectively prevent the reflection angle and installation position of the dynamic RIS body 3 from shifting. At the same time, the multiple rectangular clearance holes designed on the protective box 2 can cleverly guide the airflow to pass smoothly, thereby effectively reducing some resistance.

[0052] When a severe weather warning is issued, to prevent performance degradation or equipment damage to the dynamic RIS, the operator rotates handwheel 52 in the reverse direction. Handwheel 52 drives screw 51 to rotate in the opposite direction, which in turn drives support slide 4 downwards via threaded transmission. Support slide 4 then drives the dynamic RIS body 3 downwards. During this process, cleaning plate 13 continues to move downwards along with the dynamic RIS body 3, cleaning the reflective panel of the dynamic RIS body 3 and removing any residues that may accumulate on the dynamic RIS. Dust, dirt, and other contaminants on the surface of the reflective panel of the S-body 3 are removed to prevent them from affecting its ability to reflect and modulate signals, ensuring long-term stable operation and optimal performance. When the upper surface of the dynamic RIS body 3 returns to being flush with the upper surface of the protective box 2, the convex sliding plate 12 will extend out of the mounting sleeve 11 and return to its original position under the action of the compression spring. At the same time, during the process of the support slide 4 driving multiple racks 535 to move downward synchronously and pass through the corresponding incomplete gears 532, each corresponding rack 535 will mesh with the corresponding incomplete gear 532, and through the transmission of the racks 535 and incomplete gears 532, multiple incomplete gears 532 will be driven to rotate around the corresponding support. When rod 531 rotates in the opposite direction, multiple incomplete gears 532 will drive the corresponding support legs 533 to rotate in the opposite direction synchronously until the side of the multiple support legs 533 away from the incomplete gears 532 rotates into the corresponding rectangular clearance holes. At this time, the magnets 534 on the multiple support legs 533 and the magnets 534 embedded in the rectangular clearance holes will return to the magnetic attraction state. The protective box 2 will turn into a closed state, thereby achieving the effect of physical protection for the dynamic RIS body 3. Even if the weather conditions are too severe, there is no need for staff to temporarily retrieve the equipment or stop its operation, reducing the frequency of inspection and maintenance of the dynamic RIS body 3 and reducing long-term maintenance costs.

[0053] When the dynamic RIS body 3 needs to be disassembled, the operator manually turns the handwheel 52. The handwheel 52 drives the lead screw 51 to rotate synchronously. The lead screw 51 drives the support slide 4 to move upward through the threaded transmission. The support slide 4 drives the dynamic RIS body 3 to move upward and extend out of the protective box 2. When the working end face of the reflective panel of the dynamic RIS body 3 is completely on the upper side of the protective box 2, the lower ends of the left and right abutment slide rods 61 will be inserted into the corresponding circular slide grooves and located on the upper side of the corresponding snap-fit ​​assembly 62. Then, continue to turn the handwheel 52 to control the lead screw 51 to drive the support slide 4 to continue to move upward until the upper end of the support slide 4 is tightly attached to the inner wall of the upper end of the protective box 2. During this period, the left and right abutment slide rods 61 will continue to move along the corresponding circular slide grooves. When inserted, the two left and right abutment slide rods 61 will press the corresponding wedge-shaped abutment plates 623 respectively. The two left and right wedge-shaped abutment plates 623 will drive the corresponding front and rear wedge-shaped locking plates 622 to perform adaptive sliding compensation along the corresponding rectangular connecting groove, so that the two left and right abutment slide rods 61 can move downward smoothly. At this time, the multiple wedge-shaped locking plates 622 will move away from the corresponding locking rods 621 respectively, releasing the limiting and pressing on the locking rods 621, thereby achieving the effect of rapid disengagement of the dynamic RIS body 3 and the support slide 4. The dynamic RIS body 3 can then be pulled out by the operator, so that the multiple locking rods 621 will exit the corresponding rectangular slots respectively. At this time, under the action of the compression spring, the wedge-shaped locking plates 622 and the wedge-shaped abutment plates 623 on both sides will return to their original positions.

[0054] When the dynamic RIS body 3 needs to be installed, the staff will place the replaced dynamic RIS body 3 on the support slide 4 and insert multiple locking rods 621 into the corresponding rectangular slots. The multiple locking rods 621 will press the corresponding wedge-shaped contact plates 623. The two left and right wedge-shaped contact plates 623 will drive the two front and rear wedge-shaped locking plates 622 to perform adaptive sliding compensation along the corresponding rectangular connecting grooves, so that the two left and right locking rods 621 can move downward smoothly. Under the action of the compression spring, the wedge-shaped locking plates 622 and wedge-shaped contact plates 623 on both sides will return to their original positions and limit and tighten the locking rods 621 again. Thus, the dynamic RIS body 3 and the support slide 4 can be quickly locked together by multiple locking rods 621.

[0055] In summary, this application has the following advantages:

[0056] Firstly, when it is necessary to control the extension of the dynamic RIS body 3 to regulate the wireless channel, the installer manually rotates the handwheel 52. The handwheel 52 drives the lead screw 51 to rotate synchronously. The lead screw 51 drives the support slide 4 to move upward through the threaded transmission. The support slide 4 drives the dynamic RIS body 3 to move upward. During this process, the upper end of the dynamic RIS body 3 will press against the inner wall of the triangular inclined groove on the lower end face of the U-shaped slide plate 12, causing it to move backward and retract into the mounting sleeve 11. This achieves the effect of the dynamic RIS body 3 smoothly moving upward and extending out of the protective box 2 along the inner wall of the avoidance sliding hole on the U-shaped slide plate 12. The use of a retractable dynamic RIS body 3 also avoids the problem of the reflective panel of the dynamic RIS body 3 being easily damaged during transportation and installation.

[0057] Secondly, during the upward movement of the support slide 4 driven by the lead screw 51 through threaded transmission, the support slide 4 drives multiple racks 535 to move upward synchronously. Each corresponding rack 535 meshes with the corresponding incomplete gear 532, and through the transmission of the rack 535 and the incomplete gear 532, drives multiple incomplete gears 532 to rotate around the corresponding support rod 531. The multiple incomplete gears 532 drive the corresponding support brackets 533 to rotate synchronously until the side of the multiple support brackets 533 away from the incomplete gears 532 is flush with the installation ground. This achieves the effect of strengthening the installation stability of the dynamic RIS body 3 through triangular support by multiple support brackets 533, which can be installed and deployed in more complex environments, effectively increasing the deployment range of the dynamic RIS. In addition, since the dynamic RIS body 3 extends out of the protective box 2, the force-bearing area increases in windy environments. The additional support by multiple support brackets 533 can effectively prevent the reflection angle and installation position of the dynamic RIS body 3 from shifting. At the same time, the multiple rectangular clearance holes designed on the protective box 2 can cleverly guide the airflow to pass smoothly, thereby effectively reducing some resistance.

[0058] Thirdly, when a severe weather warning is issued, to avoid performance degradation or equipment damage to the dynamic RIS, the operator can rotate the handwheel 52 in the reverse direction. The handwheel 52 will drive the lead screw 51 to rotate synchronously in the reverse direction. The lead screw 51 will drive the support slide 4 downwards via threaded transmission. The support slide 4 will then drive the dynamic RIS body 3 downwards. Simultaneously, as the support slide 4 drives multiple racks 535 to move downwards synchronously and pass through corresponding incomplete gears 532, each corresponding rack 535 will mesh with its corresponding incomplete gear 532. Through the transmission between the racks 535 and the incomplete gears 532, multiple incomplete gears 532 will rotate around their corresponding support rods. When 531 rotates in the opposite direction, multiple incomplete gears 532 will drive the corresponding support brackets 533 to rotate synchronously in the opposite direction until the side of the multiple support brackets 533 away from the incomplete gears 532 rotates into the corresponding rectangular clearance holes. At this time, the magnets 534 on the multiple support brackets 533 and the magnets 534 embedded in the rectangular clearance holes will return to the magnetic attraction state. The protection box 2 will turn into a closed state, thereby achieving the effect of physical protection for the dynamic RIS body 3. Even if the weather conditions are too severe, there is no need for staff to temporarily retrieve the equipment or stop its operation, reducing the frequency of inspection and maintenance of the dynamic RIS body 3 and reducing long-term maintenance costs.

[0059] Fourthly, as the dynamic RIS body 3 continues to move downwards, the cleaning plate 13 will clean the reflective panel of the dynamic RIS body 3, removing dust, dirt and other contaminants that accumulate on the surface of the reflective panel of the dynamic RIS body 3, so as to avoid affecting its ability to reflect and control signals, and ensure long-term stable operation and optimal performance.

[0060] Fifthly, when the dynamic RIS body 3 needs to be disassembled, the operator manually rotates the handwheel 52 to control the screw 51 to drive the support slide 4 to continue moving upward until the upper end of the support slide 4 is tightly attached to the upper inner wall of the protective box 2. The two left and right abutment slides 61 will press the corresponding wedge-shaped abutment plates 623 respectively. The two left and right wedge abutment plates 623 will drive the corresponding front and rear wedge-shaped locking plates 622 respectively to perform adaptive sliding compensation along the corresponding rectangular connecting groove, so that the two left and right abutment slides 61 can move downward smoothly. At this time, the multiple wedge-shaped locking plates 622 will move away from the corresponding locking rods 621 respectively, releasing the limiting and pressing of the locking rods 621, thereby achieving the effect of rapid separation between the dynamic RIS body 3 and the support slide 4.

[0061] Advantage six: When the dynamic RIS body 3 needs to be installed, the staff places the replaced dynamic RIS body 3 on the support slide 4 and inserts multiple locking rods 621 into the corresponding rectangular slots. The multiple locking rods 621 will press the corresponding wedge-shaped contact plates 623. The two left and right wedge-shaped contact plates 623 will drive the corresponding front and rear wedge-shaped locking plates 622 to perform adaptive sliding compensation along the corresponding rectangular connecting grooves, so that the two left and right locking rods 621 can move downward smoothly. Under the action of the compression spring, the wedge-shaped locking plates 622 and wedge-shaped contact plates 623 on both sides will return to their original positions and limit and tighten the locking rods 621 again. Thus, the dynamic RIS body 3 and the support slide 4 are quickly locked together by multiple locking rods 621.
