Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of louver structure, and concretely relates to a building ventilation opening adjustable louver structure. BACKGROUND

[0002] In the modern building field, the ventilation opening as an indispensable component of the building shoulders the key mission of guaranteeing the indoor air circulation and adjusting the indoor environment comfort degree. It is an important channel for indoor and outdoor air exchange, like the "respiratory organ" of the building, introduces the outdoor fresh air, discharges the indoor foul gas, and creates a healthy and pleasant indoor environment for the occupants and users. The traditional building ventilation opening usually adopts a simple fixed louver structure or a louver window form only with a basic opening and closing function. These traditional ventilation openings have many drawbacks, which seriously restrict the ventilation performance and the adaptability to the building environment.

[0003] The utility model of a kind of green building's ventilation energy-saving equipment with publication number CN222068767U (application number CN202323367755.9) includes: main frame, connecting rod, ventilation louver, opening adjusting assembly, connecting rod is provided with several and is installed on main frame;Ventilation louver is installed on connecting rod.The utility model is pushed up by air cylinder starting, so that the lifting rod is moved up with lifting plate, the connecting rod is pushed, the connecting rod pushes the rod and the link block under the cooperation of sliding groove and limiting rod, to push ventilation louver, ventilation louver is pushed by connecting rod and is turned over, and the process is simple and fast, without motor drive opening, and also not blocked by motor, reduce noise and also improve ventilation effect, and connecting rod can also push ventilation louver to balance state, so that it reaches maximum ventilation opening, effectively improve ventilation efficiency.

[0004] The above-mentioned ventilation opening has obvious defects in the protection function. On the one hand, the anti-insect measure is simple, mostly relying on sparse insect-proof net, which is difficult to effectively block small insects such as mosquitoes and moths from entering the room, bringing many troubles to people's life, especially in the summer mosquito breeding season, the room is frequently invaded by mosquitoes, which seriously affects the living experience. On the other hand, in the face of rainwater invasion, the traditional ventilation opening lacks effective flow guide and anti-backflow design, and rainwater is easy to enter the room along the ventilation opening, wetting the wall surface and floor and even damaging indoor property, causing damage to the internal environment of the building. UTILITY MODEL CONTENT

[0005] Therefore, the building ventilation opening adjustable louver structure provided by the utility model improves the protection performance of the ventilation opening while enhancing the air tightness of the ventilation opening.

[0006] The utility model is implemented as follows:

[0007] The utility model provides a kind of adjustable louver structure of building air vent, wherein, include: frame main body, the frame main body is provided with inward recessed installation clamping groove, crossbar and blade assembly, the crossbar quantity is not less than three, it is connected with the frame main body by the way of embedding the installation clamping groove, and the crossbar both ends are provided with elastic buffer pad;The blade assembly includes multiple blades, the blade assembly is connected with the crossbar by hinge structure, the blade assembly adopts double-layer structure, outer layer is hard plastic plate, inner layer is soundproof foam material, and the blade assembly surface is covered with dustproof coating.

[0008] On the basis of the above technical scheme, the adjustable louver structure of building air vent of the utility model can be further improved as follows:

[0009] Among them, the edge of the frame main body is respectively provided with a flow guide groove and a screen clamping groove, the flow guide groove is in an inclined groove structure, and a hydrophobic film is attached to the inner surface of the flow guide groove; the inner wall of the screen clamping groove is provided with anti-skid lines, one side of the screen clamping groove is provided with a buckle, and the buckle is used for fixing the screen.

[0010] The rainwater flow guide groove is located at the upper and lower edges of the air vent frame main body and has an inclined groove structure. Its main function is to guide the rainwater to flow out along the frame in a directional manner and prevent the rainwater from flowing back into the air vent. Under normal circumstances, the inclination angle of the flow guide groove is optimized according to the installation position of the air vent on the building wall and the local annual wind and rain direction to ensure that the rainwater can be quickly and smoothly drained by gravity.

[0011] The insect-proof screen clamping groove is generally distributed on the side surface of the air vent frame main body, which can be on both sides or focused on one side according to actual needs, such as the side close to the direction with more mosquitoes and insects.

[0012] The beneficial effects of the above improved scheme are: the hydrophobic film is made of polytetrafluoroethylene (PTFE) material. Polytetrafluoroethylene has extremely low surface energy, so water droplets can quickly roll off its surface and are not easy to adhere, thereby efficiently realizing the hydrophobic function, effectively preventing rainwater from accumulating in the rainwater flow guide groove, ensuring that the rainwater can be smoothly drained, preventing rainwater from flowing back into the air vent, and protecting the air vent structure and indoor environment from rainwater intrusion.

[0013] The inner wall of the screen clamping groove is provided with anti-skid lines, which can increase the friction between the screen and the screen clamping groove, making the screen more stable after installation and not easy to shift or fall off, and ensuring the durability of the insect-proof effect.

[0014] Further, the crossbar is hollow inside for accommodating the air vent lighting strip.

[0015] The lighting lamp strip is a common LED lamp strip with adjustable brightness, and the switch and brightness adjustment are controlled by a manual knob arranged outside the frame body of the air vent, thereby providing supplementary lighting for the periphery of the air vent

[0016] Further, a sealing rubber strip is pasted at the joint gap between adjacent blade assemblies.

[0017] The sealing rubber strip is made of rubber material with good weather resistance, and effectively seals the air vent in the closed state of the blade to prevent dust and fine particles from entering

[0018] Further, the detachable hinge structure of the blade assembly and the crossbar adopts a plug-in connection design, the blade assembly is provided with a plug-in plug, and the crossbar is provided with a hinge seat matched with the plug-in plug.

[0019] A cylindrical plug-in plug is arranged at the connecting end of the multifunctional shutter blade assembly. The corresponding connecting part of the crossbar is provided with a hinge seat with a locking function. The hinge seat is internally provided with a cylindrical groove matched with the plug. The inner wall of the groove is lined with a layer of rubber cushion. The rubber cushion can increase the friction between the plug and the groove, so that the blade remains stable during normal use, and also has a buffering effect to reduce wear and tear during plugging and unplugging.

[0020] Further, the outer hard plastic plate of the blade assembly is provided with a flow guide groove on the leeward surface. The flow guide groove is longitudinally distributed along the length direction of the blade assembly from the top end to the bottom end.

[0021] The cross-sectional shape of the flow guide groove is arc-shaped. This arc-shaped design can better fit the flow characteristics of the airflow and guide the airflow to smoothly pass along the flow guide groove.

[0022] Further, a reinforcing steel wire is transversely arranged at the middle position of the blade assembly.

[0023] The reinforcing steel wire is made of high-strength stainless steel wire. During the shaping of the blade, the steel wire is pre-embedded in the middle layer of the double-layer structure of the blade, so that it penetrates the middle position of the blade and is arranged transversely. The two ends of the steel wire are tightly fixed with the outer hard plastic plate and the inner soundproof foam material of the blade through riveting process, so that the steel wire can evenly share the tensile force when the blade is subjected to the action of strong wind, thereby enhancing the overall wind resistance of the blade, effectively preventing the deformation and damage of the blade in strong wind weather, and ensuring the reliability and stability of the adjustable shutter structure of the air vent.

[0024] Further, the mounting clamping groove is in the shape of a rectangular groove. The length of the mounting clamping groove is equal to the length of the frame body, and a shock-absorbing rubber strip is placed in the mounting clamping groove.

[0025] Further, the crossbar is made of corrosion-resistant engineering plastic.

[0026] The crossbar is made of corrosion-resistant engineering plastic, specifically glass fiber reinforced polycarbonate (PC).

[0027] Furthermore, the frame body is made of aluminum alloy.

[0028] Compared with existing technologies, the beneficial effects of the adjustable louver structure for building ventilation openings provided by this utility model are:

[0029] The multi-functional louver blade assembly and stable adjustment bar of this structure are connected by a hinge structure that allows for easy disassembly, and the louver blade angle is flexibly adjustable. Users can easily change the opening angle of the blades manually according to different seasons, weather, and actual indoor needs, precisely controlling the ventilation volume. For example, in the pleasant spring and autumn seasons, the blades can be adjusted to an appropriate angle to achieve gentle ventilation and keep the indoor air fresh; in the hot summer, the blades can be adjusted to the maximum ventilation angle to accelerate the heat exchange between indoor and outdoor air, quickly expel stuffy air, and introduce cool fresh air, effectively reducing indoor temperature and improving human comfort. In the cold winter, the blade angle can be reduced to decrease the ventilation volume, prevent excessive heat loss from the indoor environment, reduce heating energy consumption, and achieve energy-saving ventilation.

[0030] The upper and lower edges of the vent frame are equipped with rainwater drainage channels in an inclined groove structure, with a high-efficiency hydrophobic film attached to the inner surface of the channels. This design can quickly guide rainwater to flow out along the frame during rainy weather, preventing rainwater from flowing back into the vent, effectively protecting the indoor environment from rainwater damage, ensuring a dry and comfortable interior, and extending the building's lifespan. For example, during heavy rain, when a large amount of rainwater hits the vent frame, the drainage channels act like "drainage pipes," quickly draining the rainwater away, preventing rainwater leakage even during prolonged rainfall.

[0031] The inner wall of the insect-proof mesh slot has an anti-slip texture, making it easy to install the fine insect-proof mesh tightly. One side of the slot also features an easy-opening buckle for quick and easy removal and cleaning of the mesh. The fine insect-proof mesh effectively blocks mosquitoes, moths, and other insects from entering the room, creating a comfortable, insect-free space for residents. This is especially beneficial during the summer when mosquitoes are rampant, greatly improving the quality of indoor life.

[0032] The multi-functional louver blade assembly and detachable hinge structure with a stable adjusting crossbar feature a simple plug-and-play connection design. Combined with a hinge base with a locking function, a single person can easily disassemble and replace individual blades. When blades are damaged, deformed, or require cleaning, no professional tools or complicated procedures are needed; users can quickly handle the situation themselves, greatly reducing maintenance difficulty and costs. Furthermore, the easy-opening and closing snap-lock design of the insect-proof mesh slots facilitates regular cleaning and replacement of the mesh, ensuring long-lasting and effective insect prevention.

[0037] 10. Frame body; 11. Mounting slot; 12. Crossbar; 13. Flow guide channel; 14. Mesh slot; 20. Blade assembly. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0039] like Figure 1 The image shows an embodiment of an adjustable louver structure for a building ventilation opening provided by this utility model. In this embodiment, it includes: a frame body 10, which is provided with an inwardly recessed mounting groove 11, a crossbar 12, and a blade assembly 20. The number of crossbars 12 is not less than three, which are connected to the frame body 10 by embedding into the mounting groove 11, and elastic buffer pads are provided at both ends of the crossbars 12; the blade assembly 20 includes multiple blades, and the blade assembly 20 is connected to the crossbars 12 by a hinge structure. The blade assembly 20 adopts a double-layer structure, with the outer layer being a rigid plastic plate and the inner layer being a sound-insulating foam material, and the surface of the blade assembly 20 is covered with a dustproof coating.

[0040] Furthermore, it should be noted that this utility model includes an opening adjustment component installed on the frame body and connected to the blade assembly; wherein, the opening adjustment component includes a cylinder, a mounting bracket, a lifting rod, a lifting plate, a connecting rod, a shaft, a slide groove, a limiting rod, a through rod, and a connecting block. The cylinder is mounted on the mounting bracket, one side of the lifting rod is connected to the cylinder and the other side is connected to the lifting plate, the connecting rod is rotatably connected to the lifting plate via the shaft, the limiting rod is mounted on the frame body, the connecting rod is provided with a slide groove for the limiting rod to pass through, the connecting block is connected to the blade assembly, and the through rod is mounted on the connecting block and rotatably connected to the connecting rod.

[0041] like Figure 2 As shown, in the above technical solution, the edges of the frame body 10 are respectively provided with a flow guide groove 13 and a mesh slot 14. The flow guide groove 13 has an inclined groove structure, and a hydrophobic film is attached to the inner surface of the flow guide groove 13. The inner wall of the mesh slot 14 has anti-slip texture, and a buckle is provided on one side of the mesh slot 14 for fixing the mesh.

[0042] The clips on one side of the mesh slot are push-button elastic clips. The clip bodies are made of plastic and have a certain degree of elastic deformation. When installing the insect-proof mesh, first insert one end of the mesh into the bottom of the slot, then push the mesh along the slot towards the side with the clip. When the mesh touches the clip, it causes the clip to elastically deform outwards. Continue pushing the mesh until it is fully engaged in the slot. At this point, the clip returns to its original position under its own elastic force, firmly securing the edge of the mesh and preventing it from coming out. When removing the mesh, simply press the clips to open them outwards, and the mesh can be easily pulled out, making the operation convenient and efficient.

[0043] Furthermore, in the above technical solution, the crossbar 12 is hollow inside, which is used to install the ventilation opening lighting strip.

[0044] Furthermore, in the above technical solution, a sealing strip is affixed to the splicing gap between adjacent blade assemblies 20.

[0045] Furthermore, in the above technical solution, the detachable hinge structure of the blade assembly 20 and the crossbar 12 adopts a plug-in connection design. The blade assembly 20 is provided with a plug-in plug, and the crossbar 12 is provided with a hinge seat in conjunction with the plug-in plug.

[0046] When installing a blade, align the plug on the blade with the recess in the hinge seat and insert it straight in until the bottom of the plug contacts the bottom of the recess. At this point, the rubber pad will deform under pressure, tightly gripping the plug and locking it in place to prevent the blade from accidentally falling off. When removing the blade, simply pull the plug out with a little force. The operation is simple and easy, facilitating quick replacement and maintenance of individual blades.

[0047] Furthermore, in the above technical solution, the outer rigid plastic plate of the blade assembly 20 has a flow-guiding groove on the leeward side. The flow-guiding groove is longitudinally distributed and extends from the top to the bottom along the length direction of the blade assembly 20.

[0048] Furthermore, in the above technical solution, the blade assembly 20 has a reinforcing steel wire transversely threaded through the middle of the blade.

[0049] Furthermore, in the above technical solution, the mounting slot 11 is generally rectangular in shape, the length of the mounting slot 11 is equal to the length of the frame body 10, and a shock-absorbing rubber strip is placed inside the mounting slot 11.

[0050] Furthermore, in the above technical solution, the crossbar 12 is made of corrosion-resistant engineering plastic.

[0051] Furthermore, in the above technical solution, the frame body 10 is made of aluminum alloy.

[0052] Specifically, the principle of this utility model is as follows:

[0053] The multi-functional louver blade assembly is connected to the stable adjustment bar using a specially designed hinge structure. The simple plug-and-play connection makes blade installation convenient and easy to disassemble and replace, while the locking function of the hinge seat ensures the blades are stable and reliable during normal use, preventing them from wobbling or falling off. When the user needs to adjust the ventilation volume, they can manually change the rotation angle of the blades around the hinge axis, thereby adjusting the effective ventilation area of ​​the vent. For example, rotating the blades horizontally increases the vent opening and thus increases the ventilation volume; conversely, rotating the blades vertically decreases the vent opening and reduces the ventilation volume. The ventilation volume indicator provides users with an intuitive reference; based on the different colored areas corresponding to the degree of ventilation opening, users can quickly and accurately adjust the blade angle to achieve precise ventilation control.

[0054] The rainwater drainage channels along the upper and lower edges of the vent frame are designed with an inclined groove structure. The angle of inclination is scientifically designed based on factors such as the prevailing wind and rain direction of the building's location and the vent's installation position. Generally, the inclination direction of the drainage channel is consistent with the natural flow direction of rainwater, ensuring that rainwater can flow quickly and smoothly out of the vent under gravity. The hydrophobic membrane attached to the inner surface of the channel is typically made of a material with extremely low surface energy, such as polytetrafluoroethylene (PTFE). This material prevents water droplets from adhering to its surface, causing them to form beads and roll off, greatly enhancing the flowability of rainwater and effectively preventing rainwater accumulation and backflow within the drainage channel, thus eliminating the risk of rainwater flowing back into the vent.

[0055] The insect-proof mesh slot is specially designed for installing fine insect-proof mesh. The anti-slip texture on the inner wall of the slot increases friction between the mesh and the slot, ensuring a tight fit and preventing shifting or detachment after installation. The easy-opening buckle on one side of the slot facilitates easy removal and cleaning of the mesh. To install the mesh, first insert one end of the mesh into the bottom of the slot, then push it along the slot towards the buckle. When the mesh touches the buckle, it elastically deforms outwards. Continue pushing until the mesh is fully engaged. The buckle then returns to its original position under its own elasticity, firmly securing the mesh edge and ensuring insect-proof performance. To clean or replace the mesh, simply press the buckle to open it outwards, and the mesh can be easily pulled out.
