Technical Field
[0001] This utility model belongs to the field of hollow louvered glass technology, specifically relating to a corner anti-collision device for hollow louvered glass. Background Technology
[0002] Insulating louvered glass is an energy-saving type of glass, mainly composed of two layers of glass and a set of louvered slats. The operation of the louvered slats is achieved through a magnetic control closing device and a lifting device. This allows insulating louvered glass to save space while also providing good sun-shading performance for glass doors and windows, improving the thermal insulation performance of insulating glass, and improving the indoor lighting environment. Insulating louvered glass is a versatile, cost-effective, environmentally friendly, and energy-saving type of glass.
[0003] In existing technologies, corner protection for insulated louvered glass has long been a technical bottleneck. While insulated louvered glass with built-in blinds achieves basic functionality through silicone sealant and winding devices, it lacks specific design for impact resistance at the glass corners. Traditional protective structures often employ external mating covers or thin protective pads, requiring bolts or adhesives to fix them to the outside of the frame. This is not only cumbersome to install but also limits the thickness of the protective layer, making it difficult to effectively absorb impact energy. Furthermore, existing protective devices generally suffer from poor fit to the frame surface; for example, gaps exist between the protective pad and the frame, leading to inconsistent protective effectiveness. Utility Model Content
[0004] The purpose of this invention is to provide a corner anti-collision device for hollow louvered glass to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner anti-collision device for hollow louvered glass, comprising a hollow louvered glass body and a corner anti-collision device, wherein the hollow louvered glass body comprises a frame, tempered glass and aluminum alloy louvers disposed on the inner side of the frame;
[0006] The corner anti-collision device includes an elastic protective sleeve and a reinforcing structure. The elastic protective sleeve is fitted onto the four corners of the frame, and the reinforcing structure is disposed inside the elastic protective sleeve.
[0007] The four corners of the frame are provided with L-shaped anti-collision grooves to allow the elastic sleeve to be installed flush with the surface of the frame.
[0008] Preferably, the inner wall of the elastic protective sleeve is tightly fitted to the corners of the frame. The elastic protective sleeve is made of rubber, which eliminates the gap between the traditional protective structure and the frame, avoids the problem of protection failure caused by the gap, and ensures that the protective sleeve is flush with the surface of the frame (in conjunction with the L-shaped anti-collision groove), which not only improves the protection stability, but also maintains the appearance integrity of the hollow louvered glass.
[0009] Preferably, the reinforcing structure includes metal reinforcing ribs disposed within the elastic protective sleeve. The metal reinforcing ribs extend along the corners of the frame and are integrally formed with the elastic protective sleeve to form a rigid support skeleton, which can evenly distribute external impact force to the entire frame structure and avoid corner breakage caused by local stress concentration.
[0010] Preferably, the outer side of the elastic protective sleeve is provided with a buffer layer, which is made of sponge or foam material. The buffer layer can consume most of the impact energy through its own compression deformation in the early stage of the collision, thereby reducing the impact force transmitted to the elastic protective sleeve and the frame.
[0011] Preferably, the elastic protective sleeve has anti-slip protrusions at both ends, which are in close contact with the surface of the frame to prevent the protective sleeve from shifting or falling off due to vibration or collision during transportation or use, thus ensuring the long-term stability and reliability of the protective structure.
[0012] Preferably, the reinforcing structure further includes a support block disposed inside the frame, the support block being connected to the metal reinforcing rib, which transmits external impact force to the support block inside the frame through the metal reinforcing rib, thereby dispersing it throughout the entire frame.
[0013] Preferably, the elastic protective sleeve is connected to the frame by a buckle or bolt. The buckle or bolt is located on the inner side of the elastic protective sleeve, which maintains the flatness of the glass surface and avoids the problem of corrosion or loosening of the external connector due to long-term exposure, thereby improving the ease of installation and structural durability.
[0014] Preferably, the outer surface of the elastic protective sleeve is provided with a wear-resistant coating, which is polyurethane or polytetrafluoroethylene, to extend the service life of the protective sleeve; the polyurethane or polytetrafluoroethylene coating has both high wear resistance and low coefficient of friction, which improves the durability of the protective sleeve while avoiding the decrease in cushioning performance due to surface wear, and ensures stable corner protection effect during long-term use.
[0015] Compared with the prior art, the technical effects and advantages of this utility model are: the corner anti-collision device for hollow louvered glass,
[0016] To address the problems of poor fit between the protective structure and the frame and cumbersome installation in existing technologies, this utility model eliminates the gap between the traditional protective pad and the frame by using an L-shaped anti-collision groove and an elastic protective sleeve flush design, thus avoiding protective failure caused by the gap. At the same time, the use of internal buckle / bolt connection, compared with external connectors, not only maintains the flatness and aesthetics of the glass surface, but also simplifies the installation process, solving the multiple defects of traditional protective structures such as "easy to loosen, unsightly, and difficult to install".
[0017] A four-stage energy-absorbing structure consisting of a sponge buffer layer, an elastic sleeve, metal reinforcements, and support blocks was constructed. The sponge buffer layer first absorbs the impact energy, the rubber elastic sleeve further cushions the impact, the metal reinforcements disperse stress, and the internal support blocks transmit the impact force to the entire frame. This design breaks through the energy absorption limit of traditional thin protective pads, effectively improving the impact resistance of the corners and corners, and effectively solving the core problem of fragile corners in hollow louvered glass.
[0018] With the dual protection of anti-slip protrusions and wear-resistant coating, the protective sleeve is prevented from shifting due to vibration during use, and the polyurethane / PTFE coating resists long-term friction wear, thus extending the service life of the protective device. Combined with the concealed connection structure to avoid corrosion of external parts, the entire process from structural stability to material durability has been optimized, achieving a full-cycle improvement in the reliability of protection from installation to long-term use.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4This utility model provides a technical solution: a corner anti-collision device for hollow louvered glass, including a hollow louvered glass body 1 and a corner anti-collision device 2. The hollow louvered glass body 1 continues the typical structure in the prior art, including a frame 3, tempered glass 4, and aluminum alloy louvers 5 disposed on the inner side of the frame 3. Silicone sealant is provided in the groove on the inner side of the frame 3. Two tempered glass 4 are provided. A winding device is installed below the silicone sealant on the upper inner side of the frame 3. A winding rope is installed below the winding device. An aluminum alloy louver is installed at one end of the winding rope. The aluminum alloy louver 5 can be adjusted by a magnetic control device or a winding mechanism.
[0026] The corner anti-collision device 2 is the core improvement, including an elastic protective sleeve 6 and a reinforcing structure 7. L-shaped anti-collision grooves 9 are provided at the four corners of the frame 3. These grooves are recessed inward along the right-angled edges of the frame 3, forming an installation space that matches the shape of the elastic protective sleeve 6. This ensures that the outer surface of the elastic protective sleeve 6 is flush with the outer surface of the frame 3 after installation, maintaining the overall aesthetics of the glass while avoiding the problem of traditional external protective structures protruding and easily subject to secondary impacts.
[0027] The elastic protective sleeve 6 is made of highly elastic rubber material. Its inner wall is formed by injection molding to form an arc-shaped structure that fits perfectly with the corner contour of the frame 3. During installation, the inner wall of the elastic protective sleeve 6 is tightly fitted to the right-angle corner of the L-shaped anti-collision groove 9. The elastic deformation capability of the rubber material is used to achieve a gapless fit, eliminating the installation gap between the traditional protective pad and the frame and improving the protective stability.
[0028] The reinforcing structure 7 includes a built-in metal reinforcing rib 10, preferably made of aluminum alloy or stainless steel. The rib 10 extends along the corner of the frame 3 and is integrally molded with the elastic protective sleeve 6 using a single injection molding process. This allows the metal reinforcing rib 10 to be completely embedded within the rubber elastic protective sleeve 6, forming a composite structure that combines rigidity and flexibility. When the corner is impacted, the metal reinforcing rib 10 can evenly distribute the impact force across the entire frame 3, preventing corner breakage caused by localized stress concentration.
[0029] The outer surface of the elastic protective sleeve 6 is covered with a buffer layer 11, which is made of low-density sponge or foam material, with a thickness of 3-5 mm, and is fixed to the outer surface of the elastic protective sleeve 6 by adhesive bonding or secondary injection molding. As a primary energy absorption structure, the buffer layer 11 can absorb 60%-70% of the impact energy through material compression deformation in the initial stage of the collision, reducing the impact force transmitted to the elastic protective sleeve 6 and the frame 3.
[0030] The elastic protective sleeve 6 has anti-slip protrusions 12 at both ends (i.e., the ends along the length of the frame 3). The anti-slip protrusions 12 are spaced hemispherical or prismatic structures made of rubber of the same material as the elastic protective sleeve 6. Their outer surface is in close contact with the plane part of the frame 3. By increasing the friction of the contact surface, the protective sleeve is prevented from sliding axially during transportation vibration or installation. Together with the positioning function of the L-shaped anti-collision groove 9, a double fixing structure of "groove + friction" is formed.
[0031] The reinforcing structure 7 also includes a support block 13 disposed inside the frame 3. The support block 13 is a cubic structure made of aluminum alloy or engineering plastic and is fixed to the inner cavity of the frame 3 by bolts or glue. The outer end of the support block 13 is connected to the inner end of the metal reinforcing rib 10 through a groove-tenon structure. When the metal reinforcing rib 10 is subjected to impact force, the force can be transmitted to the overall frame of the frame 3 through the support block 13, forming a three-dimensional reinforcement system of "outer rib and inner support", which further improves the impact resistance of the corners.
[0032] The connection between the elastic protective sleeve 6 and the frame 3 includes two optional options: buckle 14 or bolt. The buckle 14 is a barbed structure made of elastic plastic, evenly distributed on the inner wall of the elastic protective sleeve 6. During installation, it is engaged in the reserved slot of the L-shaped anti-collision groove 9 to achieve quick assembly and disassembly. The bolt connection is fixed by countersunk bolts that penetrate the inner wall of the elastic protective sleeve 6 and the frame 3. It is suitable for scenarios that require higher connection strength. The components of both connection methods are hidden inside the elastic protective sleeve 6 and do not affect the flatness of the outer surface of the glass.
[0033] The outer surface of the elastic protective sleeve 6 is also coated with a wear-resistant coating 15. The coating material is polyurethane or polytetrafluoroethylene, with a thickness of 0.1-0.3 mm, and is formed by spraying or dipping. The wear-resistant coating 15 can effectively resist friction loss during transportation, scratches from installation tools, and wind and sand erosion during long-term use, extending the service life of the protective sleeve. At the same time, its low coefficient of friction can reduce surface stress concentration during collisions.
[0034] The installation process of this device is as follows: First, L-shaped anti-collision grooves 9 are processed at the four corners of the frame 3. After the metal reinforcing ribs 10 are pre-connected with the support blocks 13, they are embedded into the mold of the elastic protective sleeve 6. The elastic protective sleeve 6 with the reinforcing structure 7 is obtained by integral injection molding. Then, the buffer layer 11 is bonded to the outside of the elastic protective sleeve 6, and anti-slip protrusions 12 are processed at both ends and coated with a wear-resistant coating 15. Finally, the elastic protective sleeve 6 is fixed in the L-shaped anti-collision grooves 9 by the buckles 14 or bolts on the inside, ensuring that the outer surface is flush with the frame 3.
[0035] Specifically, during use, when the device is impacted, the outer buffer layer 11 (sponge or foam material) comes into contact with the impact force first. Due to its high elasticity and porous structure, it undergoes compression deformation, absorbing 60% to 70% of the initial impact energy, greatly reducing the intensity of the subsequent impact force. The remaining impact force then acts on the elastic protective sleeve 6. The rubber elastic protective sleeve 6 further buffers the impact force through its own elastic deformation, converting the impact force into elastic potential energy and preventing the glass corners from directly bearing high-intensity impacts.
[0036] Stress dispersion principle: The built-in metal reinforcing rib 10 and the elastic protective sleeve 6 are integrally formed and extend along the corners of the frame 3 to form a rigid skeleton. When the impact force is transmitted to the metal reinforcing rib 10, it will evenly distribute the impact force to the entire frame 3 due to its high strength characteristics, avoiding local stress concentration. At the same time, the support block 13 inside the frame 3 is connected to the metal reinforcing rib 10. Through the groove-tenon structure, the force is further transmitted to the overall frame of the frame 3, forming a three-dimensional reinforcement system of "external rib and internal support", so that the entire frame can be stressed together and effectively prevent the corners from breaking.
[0037] Structural fixing principle: The L-shaped anti-collision grooves 9 at the four corners of the frame 3 match the shape of the elastic protective sleeve 6. The inner wall of the elastic protective sleeve 6 fits tightly into the groove, achieving precise positioning. At the same time, the anti-slip protrusions 12 at both ends of the elastic protective sleeve 6 are in close contact with the surface of the frame 3, increasing friction and preventing the protective sleeve from sliding along the axial direction of the frame. In addition, the elastic protective sleeve 6 is firmly fixed in the L-shaped anti-collision grooves 9 by the buckles 14 or bolts on the inner side, forming a triple fixing structure of "groove positioning + friction anti-movement + fastening of connecting parts", ensuring that the protective device remains stable during transportation, installation and use.
[0038] Durable protection principle: The wear-resistant coating 15 (polyurethane or polytetrafluoroethylene) on the outer surface of the elastic protective sleeve 6 has high wear resistance and low coefficient of friction, which can resist friction during transportation, scratches from installation tools, and wind and sand erosion during long-term use, preventing wear on the surface of the elastic protective sleeve 6, thereby maintaining its cushioning performance and structural strength; at the same time, the hidden buckle 14 or bolt connection on the inside avoids the connection parts from rusting and loosening due to long-term exposure, ensuring the long-term reliability of the connection structure and extending the overall service life of the device.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
