Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel panels, specifically to an aluminum single-panel splicing structure that prevents loosening at the joints. Background Technology

[0002] Aluminum single-panel splicing structure is a construction method that combines multiple aluminum single panels into a complete curtain wall or ceiling system through connecting components. It mainly includes panel edge bending, corner bracket fixing, sealing and filling, etc. Common splicing methods include butt splicing, inlaid strip splicing, and snap-fit ​​splicing. The structural design needs to take into account strength, waterproofness, and thermal expansion and contraction allowance. Fluorocarbon sprayed aluminum panels are usually used with aluminum alloy keel. The joints are filled with weather-resistant adhesive and built-in elastic strips to form movable flexible nodes. This modular structure has the characteristics of lightweight, corrosion resistance and convenient construction, and can achieve a variety of three-dimensional shapes such as plane and curved surfaces.

[0003] Existing aluminum panel snap-fit ​​splicing structures typically use a combination of clips and brackets for positioning and installation. While this design facilitates disassembly and reassembly, the brackets gradually wear down due to repeated friction after multiple disassemblies and reinstallations. With increasing usage, the gap between the brackets and clips gradually widens, leading to loosening of the snap-fit ​​and affecting the installation accuracy and overall stability of the aluminum panels. Especially under wind pressure or vibration environments, a loose snap-fit ​​structure may cause aluminum panels to shift, make abnormal noises, or even fall off, affecting the safety and aesthetics of the curtain wall or ceiling. Furthermore, long-term wear may reduce the durability of the structure and increase later maintenance costs.

[0004] In summary, to improve the long-term stability and repeated assembly / disassembly performance of aluminum single-panel modular splicing structures, it is necessary to address the wear problem caused by repeated friction of the card holder, ensuring that the fit between the card claw and the card holder remains tight and reliable at all times. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum single-panel splicing structure that prevents loosening at the joint. By setting multiple rotatable and switchable brackets, when one bracket is worn, another bracket can be rotated to switch the connection, ensuring the reliability of the connection and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum single-panel splicing structure for preventing loosening at joints, comprising a fixed shell, multiple fixed ears fixed on the outer side of the fixed shell, a fixed block installed inside the fixed shell, a slot opened on the fixed block, a rotating block rotatably connected inside the slot, multiple circular grooves opened on the rotating block, a fixed seat fixed on the rotating block, multiple card seats corresponding to the circular grooves installed on the outer side of the fixed seat, a card rod inserted into one side of the fixed shell, an mounting plate fixed on the card rod, a slide block slidably connected to the fixed block, a moving mechanism provided on the outer side of the slide block, a roller rotatably connected to the slide block, a protective component provided on the front side of the fixed shell, and a positioning mechanism provided on the protective component.

[0007] Preferably, the moving mechanism includes a pushing component and a guiding component. The pushing component is disposed at the end of the slide, and the guiding component is disposed inside the fixed housing. The pushing component is used to drive the slide to slide, and the guiding component is used to limit the sliding direction of the slide.

[0008] Preferably, the actuating assembly includes a lead screw rotatably connected to the end of the slide and a knob mounted on the end of the lead screw, the knob being used to drive the lead screw to rotate, and the lead screw being threadedly connected to the side wall of the fixed housing.

[0009] Preferably, the guide assembly includes a limiting rod disposed inside the fixed housing, a fixed plate fixed to the limiting rod, a fixing screw connected to the fixed plate, and a slide groove formed on the slide block. The limiting rod is slidably connected to the slide groove, and the fixed plate is fixedly connected to the fixed housing by the fixing screw.

[0010] Preferably, the protective component includes a cover plate disposed on the front side of the fixed housing, a slot formed on the outside of the fixed housing, a spring piece fixed on the cover plate, and a locking block fixed on the spring piece, wherein the locking block is adapted to the slot.

[0011] Preferably, the positioning mechanism includes a micro-motion component and a spring component. The spring component is used to push the micro-motion component into the circular groove, and the micro-motion component is used to drive the rotating block to rotate slightly.

[0012] Preferably, the micro-motion component includes a sleeve fixed to the cover plate and a slide rod slidably connected inside the sleeve. The end of the slide rod is semi-circular and fits against the rotating block.

[0013] Preferably, the elastic component includes a limiting block fixed to the outside of the slide rod and a spring fixed inside the sleeve, the limiting block being slidably connected to the sleeve and the spring being fixedly connected to the slide rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention effectively improves the durability and ease of maintenance of the aluminum panel splicing system by setting up multiple rotatable and switchable bracket structures. When a bracket becomes worn due to frequent disassembly and assembly, it can be easily rotated to a spare bracket to restore a tight connection, significantly extending the service life of the overall structure. This multi-bracket rotation mechanism not only avoids the drawback of having to replace the entire bracket after it wears out, but also maintains stable connection strength, ensuring that the aluminum panel does not shift or loosen under external forces such as wind pressure and vibration. This significantly reduces the difficulty and cost of later maintenance. By recycling bracket resources, the splicing nodes maintain long-term reliable mechanical properties, providing a more sustainable solution for building curtain walls and ceiling systems.

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] Refer to the instruction manual appendix Figures 1 to 7A splicing structure for preventing loosening of aluminum single-panel joints includes a fixed shell 1, multiple fixed ears 2 fixed on the outer side of the fixed shell 1, a fixed block 3 installed inside the fixed shell 1, a slot on the fixed block 3, a rotating block 4 rotatably connected inside the slot, multiple circular grooves 5 on the rotating block 4, a fixed seat 6 fixed on the rotating block 4, multiple card seats 7 corresponding to the circular grooves 5 installed on the outer side of the fixed seat 6, a card rod 8 inserted into one side of the fixed shell 1, an mounting plate 9 fixed on the card rod 8, a slide block 10 slidably connected to the fixed block 3, a moving mechanism provided on the outer side of the slide block 10, a roller 14 rotatably connected to the slide block 10, a protective component provided on the front side of the fixed shell 1, and a positioning mechanism provided on the protective component.

[0026] It should be noted that the fixed shell 1 is fixed to the aluminum single panel through the fixed ear 2, and the clamping rod 8 is fixed to the aluminum single panel through the mounting plate 9. Multiple clamping seats 7 are set on the rotating block 4, which cooperate with the insertable clamping rod 8 to achieve the clamping and fixing of the aluminum single panel. When a clamping seat 7 is worn, the roller 14 can be driven by the slide 10 and the moving mechanism to contact the corner of the rotating block 4, push it to rotate and switch to the position of the spare clamping seat 7, thereby restoring a tight connection.

[0027] Refer to the instruction manual appendix Figure 3 and Figure 4 The moving mechanism includes a pushing component and a guiding component. The pushing component is located at the end of the slide 10, and the guiding component is located inside the fixed housing 1. The pushing component is used to drive the slide 10 to slide, and the guiding component is used to limit the sliding direction of the slide 10.

[0028] It should be noted that the pushing component can drive the slide 10 to perform controllable linear motion within the fixed housing 1 and limit its direction of motion through the guiding component, ensuring that the slide 10 moves smoothly and accurately.

[0029] Refer to the instruction manual appendix Figure 3 and Figure 4 The actuating component includes a lead screw 111 rotatably connected to the end of the slide block 10 and a knob 112 mounted on the end of the lead screw 111. The knob 112 is used to drive the lead screw 111 to rotate. The lead screw 111 is threadedly connected to the side wall of the fixed housing 1.

[0030] It should be noted that by manually rotating the knob 112, the lead screw 111 is driven to rotate. Utilizing the threaded engagement between the lead screw 111 and the side wall of the fixed housing 1, the two sides of the slide 10 are respectively in contact with the inner wall of the fixed housing 1 and the surface of the fixed block 3, converting the rotational motion into the linear displacement of the slide 10, thereby realizing the function of driving the slide 10 to slide.

[0031] Refer to the instruction manual appendix Figure 3 and Figure 4The guide assembly includes a limiting rod 113 disposed inside the fixed housing 1, a fixing plate 114 fixed on the limiting rod 113, a fixing screw 115 connected to the fixing plate 114, and a sliding groove opened on the slide block 10. The limiting rod 113 is slidably connected to the sliding groove, and the fixing plate 114 is fixedly connected to the fixed housing 1 by the fixing screw 115.

[0032] It should be noted that by utilizing the sliding engagement between the limiting rod 113 and the sliding groove on the slide block 10, the slide block 10 is constrained to move only in a straight line along the length direction of the limiting rod 113, preventing it from deflecting or shaking, and ensuring accurate movement trajectory.

[0033] Refer to the instruction manual appendix Figure 1 and Figure 7 The protective components include a cover plate 131 disposed on the front side of the fixed housing 1, a slot 132 opened on the outside of the fixed housing 1, a spring piece 133 fixed on the cover plate 131, and a locking block 134 fixed on the spring piece 133, the locking block 134 being adapted to the slot 132.

[0034] It should be noted that the cover plate 131 is used to protect the rotating block 4, the card seat 7 and other components inside the fixed shell 1. The cover plate 131 is engaged and fixed with the card slot 132 on the outside of the fixed shell 1 by the card block 134 on the spring piece 133, which facilitates disassembly and maintenance.

[0035] Refer to the instruction manual appendix Figures 1 to 6 The positioning mechanism includes a micro-motion component and a spring component. The spring component is used to push the micro-motion component into the circular groove 5, and the micro-motion component is used to drive the rotating block 4 to rotate slightly.

[0036] It should be noted that after the rotating block 4 is switched into position, the positioning mechanism uses the force of the elastic component to push the micro-motion component into the circular groove 5 of the rotating block 4, thereby pushing the rotating block 4 to rotate slightly, so that its corners are exposed at the top of the fixed block 3, so that the roller 14 can contact the corners of the rotating block 4.

[0037] Refer to the instruction manual appendix Figures 1 to 6 The micro-motion component includes a sleeve 121 fixed on the cover plate 131 and a slide rod 122 slidably connected inside the sleeve 121. The end of the slide rod 122 is semi-circular and fits against the rotating block 4.

[0038] It should be noted that, under the action of the elastic component, its slide rod 122 can slide into the circular groove 5 of the rotating block 4.

[0039] Refer to the instruction manual appendix Figure 2 and Figure 6 The elastic component includes a limiting block 123 fixed to the outside of the slide rod 122 and a spring 124 fixed inside the sleeve 121. The limiting block 123 is slidably connected to the sleeve 121, and the spring 124 is fixedly connected to the slide rod 122.

[0040] It should be noted that the elastic force of the internal spring 124 continuously acts on the slide rod 122, always providing a thrust towards the rotating block 4, ensuring that the slide rod 122 can effectively drive the rotating block 4 to rotate slightly.

[0041] Working principle: During installation, insert the clamping rod 8 into the fixed housing 1, so that it engages with the specific clamping seat 7 on the rotating block 4, thereby securing the two aluminum panels. When the clamping seat 7 becomes loose due to wear from repeated disassembly and assembly, the operator can manually rotate the knob 112. The knob 112 drives the lead screw 111 to rotate. Since the lead screw 111 is threaded to the side wall of the fixed housing 1, and the two sides of the slide block 10 are respectively attached to the inner wall of the fixed housing 1 and the surface of the fixed block 3, the rotation of the lead screw 111 will drive the slide block 10 to slide smoothly away from the rotating block 4 along the limiting rod 113 until the roller 14 is no longer attached to the side of the rotating block 4. After this switching process is completed, the end of the slide rod 122 will slide into the corresponding circular groove on the rotating block 4 under the continuous thrust of the internal spring 124. When the end of the slide bar 122 enters the circular groove 5, it generates a slight lateral thrust, causing the rotating block 4 to undergo a small additional rotation, ensuring that its corner protrudes precisely from the top of the fixed block 3, so that the roller 14 can stably contact and position the corner. The roller 14 on the slide block 10 moves accordingly, and then the screw 111 is rotated in the opposite direction, causing the slide block 10 to move in the opposite direction. Finally, the roller 14 abuts against one corner of the rotating block 4. The knob 112 is rotated again, and the slide block 10 continues to move forward. The roller 14 pushes the corner of the rotating block 4, forcing the rotating block 4 to rotate in the groove of the fixed block 3 until the next unworn spare card holder 7 is switched to the corresponding snap-fit ​​position of the card bar 8. At this time, the card bar 8 can be snapped tightly into the new card holder 7 again, restoring the stability of the connection.
