Description

Technical Field

[0001] This utility model relates to the field of venetian blind technology, and in particular to a venetian blind assembly. Background Technology

[0002] Currently, louvers can be installed on building windows, warehouse ventilation openings, heat dissipation ventilation openings of some large industrial equipment, or protective railings. They can ensure ventilation while preventing dust, debris, and other contaminants from entering the room or the equipment.

[0003] However, for some larger louvers or louvers used in poor ventilation conditions (such as strong winds), the support frame is prone to deformation, and the guide vanes are prone to swaying or displacement, which reduces the reliability and safety of the louvers and shortens their service life.

[0004] Furthermore, the lack of an effective positioning structure during processing makes it difficult to determine the accurate position of the reinforcing ribs during installation, which can easily lead to inaccurate installation positions, resulting in rework and reduced processing efficiency. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a louver assembly, which provides an installation position reference for the reinforcing member by setting a positioning member at the ventilation opening, thereby avoiding rework caused by inaccurate installation position of the reinforcing strip.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A venetian blind assembly, comprising,

[0008] A support frame is provided with multiple guide vanes, which are spaced apart along a first direction and extend along a second direction perpendicular to the first direction; ventilation openings are formed between adjacent guide vanes.

[0009] A positioning element, wherein the positioning element is disposed within the ventilation opening;

[0010] A reinforcing member is disposed on one side of the support frame and connected to the positioning member.

[0011] Furthermore, the positioning element includes a positioning post that extends along the first direction, and the two ends of the positioning post are respectively connected to two adjacent guide vanes.

[0012] Furthermore, the positioning element includes a positioning strip that extends through a plurality of the guide vanes along the first direction, and the segment of the positioning strip that passes through the vent forms the positioning post.

[0013] Furthermore, the reinforcing member includes a first reinforcing strip that extends along the first direction and is connected to the positioning posts within the plurality of ventilation openings.

[0014] Furthermore, the ventilation opening is provided with at least two positioning posts, which are spaced apart along the second direction; the reinforcing member includes a second reinforcing strip that extends along the second direction, and the two ends of the second reinforcing strip are respectively connected to the two positioning posts of the same ventilation opening.

[0015] Furthermore, at least two first reinforcing strips are provided, and the at least two first reinforcing strips are spaced apart in the second direction and connected to the second reinforcing strip.

[0016] Furthermore, at least two second reinforcing strips are provided, and the at least two second reinforcing strips are spaced apart in the first direction; the first reinforcing strip is connected to the at least two second reinforcing strips.

[0017] Furthermore, the upper end of the vent is provided with air guide vanes.

[0018] Furthermore, the support frame includes a support plate and a frame, the frame being connected to the outer periphery of the support plate, and a plurality of the guide vanes being connected to the support plate; the frame is provided with a connecting part, the connecting part being used to connect with an external frame.

[0019] Furthermore, the connecting part includes a connecting plate, which is provided with a connecting groove and / or a connecting hole.

[0020] In summary, the louver assembly provided by this utility model has the following technical effects:

[0021] 1) The positioning component of this utility model provides an installation position reference for the reinforcing component. Since the positioning component is already in a specific position inside the ventilation opening, when the reinforcing component is to be installed, the machining personnel can accurately install the reinforcing component in the correct position through the positioning of the positioning component, which helps to improve machining efficiency and reduce rework caused by inaccurate installation position.

[0022] 2) At the same time, the reinforcement can enhance the working strength of the entire component. Especially in some large-sized louvers or in applications with poor ventilation (such as strong wind environments), the reinforcement can effectively prevent the support frame from deforming, the guide vanes from shaking or shifting, etc., ensuring the reliability and safety of the louvers during long-term use and extending their service life.

[0029] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] See Figures 1 to 4 This utility model discloses a louver assembly, which includes a support frame 10, a positioning member 12, and a reinforcing member. Specifically, the support frame 10 is provided with a plurality of guide vanes 21, which are arranged at intervals along a first direction and extend along a second direction perpendicular to the first direction. Ventilation openings 11 are formed between adjacent guide vanes 21. (See reference...) Figure 1 The positioning element 12 is located inside the ventilation opening 11; see reference. Figure 2 and Figure 3 The reinforcing member is located on one side of the support frame 10 and is connected to the positioning member 12.

[0033] Based on this structure, when using the louver assembly of this utility model, when it is necessary to install the louver assembly, first fix the support frame 10 in a predetermined position, such as the window frame of the building or the frame of the louver box.

[0034] When louvers are installed in building windows or louvered boxes, the ventilation openings 11 formed between the guide vanes 21 serve as channels for air circulation. The guide vanes 21 can, to some extent, prevent dust, debris, rainwater, and other external elements from entering the room or louvered box, acting as a preliminary protective barrier while providing ventilation, and can to some extent protect other equipment or components inside the ventilation openings 11 from damage.

[0035] The support frame 10 provides the basic framework structure for the entire louver assembly, ensuring that the multiple guide vanes 21 can be stably arranged at intervals and withstand their own weight and external forces such as wind. The reinforcing member is connected to the positioning member 12 and located on one side of the support frame 10, enhancing the structural strength and stability of the entire assembly.

[0036] It should be noted that when processing the louver assembly, the positioning element 12 provides an installation position reference for the reinforcing element. Since the positioning element 12 is already in a specific position within the vent 11, when installing the reinforcing element, the operator can accurately install the reinforcing element in the correct position by using the positioning element 12, which helps to improve processing efficiency and reduce rework caused by inaccurate installation position.

[0037] Therefore, the connection between the reinforcing member and the positioning member 12 facilitates processing. It also enhances the overall strength of the assembly, especially in applications with larger louvers or harsh ventilation conditions (such as strong winds). The reinforcing member effectively prevents deformation of the support frame 10, swaying or displacement of the guide vanes 21, ensuring the reliability and safety of the louvers during long-term use and extending their service life.

[0038] Further, see Figure 1 The positioning element 12 includes a positioning post. Specifically, the positioning post extends along a first direction, and its two ends are respectively connected to two adjacent guide vanes 21.

[0039] The first direction is the vertical direction, and the second direction is the horizontal direction.

[0040] Based on this structure, when assembling the louver assembly, the positioning post can be installed between two adjacent guide vanes 21. Specifically, the positioning post is inserted along the first direction (i.e., the direction in which the guide vanes 21 are spaced apart), so that both ends of the positioning post are tightly connected to the two guide vanes 21 respectively. Then, the reinforcing member is placed on one side of the mounting bracket and connected to the positioning post.

[0041] The positioning post and the guide plate 21 can be connected in several ways. For example, the guide plate 21 can have pre-set holes that match the positioning post, and the positioning post can be firmly fixed between the two guide plates 21 by interference fit or by using some auxiliary fasteners (such as small screws, retaining rings, etc.). When the louver assembly is made of metal materials such as aluminum alloy, the positioning post and the guide plate 21 can also be welded. In addition, the reinforcing strip can also be welded to the positioning post.

[0042] The positioning post extends along the first direction and connects two adjacent guide vanes 21, which keeps the spacing between the guide vanes 21 fixed, thus ensuring that the size and shape of the vent 11 are regular. During the long-term use of the louvers, whether subjected to external forces such as wind and vibration, or with frequent adjustments to the angle of the guide vanes 21, the positioning post can prevent the distance between the guide vanes 21 from changing.

[0043] Furthermore, the positioning element 12 includes a positioning strip, and the positioning strip extends through a plurality of guide vanes 21 along a first direction. The segment of the positioning strip passing through the vent 11 forms the positioning post.

[0044] Based on this structure, each guide vane 21 is provided with a mounting hole or mounting groove extending along the first direction. When assembling the louver assembly, the positioning strip needs to be passed through the mounting holes or mounting grooves of multiple guide vanes 21 along the first direction. When the positioning strip passes through the vent 11, this section forms a positioning post. At this time, the two ends of the positioning post can be tightly connected to the adjacent guide vane 21, specifically by welding or by fasteners such as screws.

[0045] When installing the reinforcing member, the reinforcing member can be aligned and connected with the positioning post in the vent 11, so that the reinforcing member is accurately installed on one side of the support frame 10, so that a stable connection is formed between the reinforcing member, the positioning strip, the guide plate 21 and the support frame 10.

[0046] Thus, the positioning strip runs through multiple guide vanes 21, connecting them into a more compact integrated structure, making each guide vane 21 interconnected and able to jointly withstand external forces. At the same time, the positioning strip effectively prevents the guide vanes 21 from shifting and deforming during long-term use, providing a stable constraint for the guide vanes 21, so that the guide vanes 21 can maintain the correct position and shape when subjected to various external forces.

[0047] Further, see Figure 2 and Figure 3 The reinforcing member includes a first reinforcing strip 15, specifically, the first reinforcing strip 15 extends along a first direction and is connected to positioning posts within a plurality of vents 11.

[0048] Based on this structure, when installing the reinforcing member, the first reinforcing strip 15 is first placed along the first direction on one side of the support frame 10, so that its position corresponds to the positioning posts in the multiple ventilation openings 11. The first reinforcing strip 15 may be provided with a slot or collar structure adapted to the positioning post. The slot on the first reinforcing strip 15 is aligned with the positioning post, and then the first reinforcing strip 15 is pushed along the direction of the positioning post, causing the positioning post to insert into the slot, thereby achieving a secure connection between the two.

[0049] During the use of the venetian blinds, when subjected to external wind, vibration, or other forces, the first reinforcing strip 15 and the positioning posts work together. For example, when wind blows towards the venetian blinds from one side, the wind force exerts pressure on the guide vane 21, and this pressure is transmitted to the first reinforcing strip 15 through the positioning posts. Because the first reinforcing strip 15 extends along the first direction, it can integrate the forces distributed on each positioning post, transmitting and dispersing them along its own length, thus preventing damage to components caused by excessive local stress.

[0050] Thus, the first reinforcing strip 15 extends along the first direction and connects with the positioning posts in the multiple ventilation openings 11, thereby strengthening the structure of the entire louver assembly and effectively improving the louver's resistance to deformation.

[0051] Furthermore, in this embodiment, both the mounting bracket 10 and the guide vane 21 are made of metal alloy. Therefore, the first reinforcing strip 15 can be made of steel, and the positioning strip can also be made of steel. In this way, the first reinforcing strip 15 can be welded and fixed to the positioning post, which greatly enhances its resistance to deformation.

[0052] Furthermore, the vent 11 is provided with at least two positioning posts, and the at least two positioning posts are spaced apart along the second direction. In addition, the reinforcing member includes a second reinforcing strip, and the second reinforcing strip extends along the second direction. The two ends of the second reinforcing strip are respectively connected to the two positioning posts of the same vent 11.

[0053] Based on this structure, when assembling the louvers, multiple positioning strips can be arranged at intervals along the second direction, and then each positioning strip can be extended along the first direction and pass through each guide vane 21. In this way, multiple positioning strips form multiple positioning posts in the same ventilation opening 11, and multiple positioning posts are arranged at intervals along the second direction.

[0054] After the positioning posts are installed, place the second reinforcing strip along the second direction, aligning its two ends with the two positioning posts inside the same ventilation opening 11. Then, using a suitable connection method, such as welding, bolting, or a special clamp, tightly connect the two ends of the second reinforcing strip to the positioning posts.

[0055] Therefore, when external force is applied to the louver, the second reinforcing strip can share the load borne by the positioning posts. Since it connects multiple positioning posts in the second direction, the force can be transmitted and distributed among the multiple positioning posts through the second reinforcing strip. This avoids excessive pressure on a single positioning post, extends the service life of the positioning posts and the guide vane 21, and improves the durability of the entire louver assembly.

[0056] Meanwhile, multiple positioning posts are spaced apart along the second direction, providing convenient positioning for the installation of the second reinforcing strip and improving the efficiency of processing and installation.

[0057] Furthermore, at least two first reinforcing bars 15 are provided, and the at least two first reinforcing bars 15 are spaced apart in the second direction and connected to the second reinforcing bar.

[0058] Based on this structure, during the assembly of the louver assembly, multiple first reinforcing strips 15 can be placed along a first direction on one side of the support frame 10. These first reinforcing strips 15 are spaced apart in a second direction, and their positions should correspond to the positioning posts within the vent 11. The first reinforcing strips 15 are securely connected to the positioning posts by means of welding, slot connection, or bolt connection.

[0059] After the first reinforcing strip 15 is installed, the second reinforcing strip is extended along the second direction and installed on the two positioning posts of the same vent 11. At this time, the second reinforcing strip needs to be connected to the first reinforcing strip 15, which is spaced apart.

[0060] Therefore, when the louvers are subjected to external force, the first reinforcing strip 15 and the second reinforcing strip will work together. In the first direction, the multiple first reinforcing strips 15 distribute the force to each positioning post, while in the second direction, the second reinforcing strip connects two positioning posts within the same vent 11, so that the force can also be effectively transmitted and distributed in the second direction.

[0061] Furthermore, at least two second reinforcing strips are provided, and the at least two second reinforcing strips are spaced apart in the first direction. The first reinforcing strip 15 is connected to the at least two second reinforcing strips.

[0062] Based on this structure, the two ends of the second reinforcing strip can be connected to the two positioning posts of the same vent 11. The connection method can be welding, bolting, or other similar methods. During installation, it is essential to ensure that the spacing of the second reinforcing strips in the first direction is uniform and that the connection to the positioning posts is secure, guaranteeing their positional accuracy. Then, the first reinforcing strips 15 are installed, with at least two first reinforcing strips 15 spaced apart along the second direction, and connected to the already installed second reinforcing strips.

[0063] When the louvers are subjected to external force, the force is transmitted to the guide vanes 21 and the positioning posts. At this time, the first reinforcing strip 15 and the second reinforcing strip cooperate to disperse and bear the external force. In the first direction, multiple second reinforcing strips disperse the force to the positioning posts corresponding to each vent 11, while in the second direction, the first reinforcing strip 15 further disperses the force to different combinations of second reinforcing strips and positioning posts.

[0064] Thus, by setting multiple first reinforcing strips 15 and multiple second reinforcing strips, a complex three-dimensional reinforcement structure is formed, which can effectively enhance the structural strength of the louver assembly in two directions. In the first direction, the second reinforcing strips reinforce the structure between the vents 11 like "crossbeams"; in the second direction, the first reinforcing strips 15 further enhance the stability of the entire assembly like "longitudinal beams".

[0065] Furthermore, the upper end of the vent 11 is provided with a guide vane 16.

[0066] Specifically, the air guide vane 16 can be fixedly or movably mounted at the vent 11, and can be fixed to the corresponding part of the support frame 10 or the air guide plate 21 by means of connection such as slots, hinges or screws. During the use of the louvers, the angle of the air guide vane 16 can be adjusted according to the actual ventilation needs and airflow direction.

[0067] The guide vane 16 guides the airflow through the vent 11, changing its direction so that it enters the room or equipment in the desired direction. In windy or rainy weather, adjusting the guide vane 16 to a suitable angle can provide some degree of obstruction.

[0068] Further, see Figures 1 to 3 The support frame 10 includes a support plate 13 and a frame 14. Specifically, the frame 14 is connected to the outer periphery of the support plate 13, and multiple guide vanes 21 are connected to the support plate 13. The frame 14 is provided with a connecting part for connecting to an external frame.

[0069] Based on this structure, during assembly, multiple guide vanes 21 are first installed on the support plate 13. This can be achieved in various ways, such as pre-setting slots or screw holes on the support plate 13, with matching clips or screw holes at both ends of the guide vanes 21. The guide vanes 21 are then securely installed on the support plate 13 by snapping or screw fixing, ensuring that the guide vanes 21 are evenly spaced along the first direction and extend along the second direction.

[0070] Next, the frame 14 is connected to the outer periphery of the support plate 13. The frame 14 and the support plate 13 can be connected by welding or screw fixing. For example, corresponding connection holes 18 are provided at the contact edges of the frame 14 and the support plate 13, and they are tightly connected together by screws to form a complete support frame 10 structure.

[0071] After the support frame 10 is assembled, it is installed onto the external frame, such as the window frame or ventilation duct frame of a building, using the connecting parts on the frame 14.

[0072] During daily use of the blinds, the support frame 10 bears the weight of the guide vane 21, wind force, and possible vibrations. The frame 14 and the support plate 13 work together to maintain the stability of the entire structure. When wind blows, the pressure generated by the wind on the guide vane 21 is transmitted to the support plate 13, and then the support plate 13 distributes the force to the frame 14. The frame 14 transmits the force to the outer frame through the connecting parts, thereby ensuring that the blinds can be stably fixed in the predetermined position.

[0073] Therefore, the support plate 13, as the main load-bearing component, provides a mounting base for the multiple guide vanes 21. It ensures that the guide vanes 21 can be stably spaced and can withstand the weight of the guide vanes 21 themselves during use.

[0074] Further, see Figure 3 and Figure 4 The connecting part includes a connecting plate 17, and the connecting plate 17 is provided with a connecting groove 19 and / or a connecting hole 18.

[0075] Specifically, the connecting plate 17 is disposed around the perimeter of the frame 14, and the connecting plate 17 can extend laterally or vertically away from the frame 14.

[0076] Based on this structure, when connecting the louver components, the connecting groove 19 or connecting hole 18 is selected for connection according to the corresponding connection structure on the external frame (such as a building window frame or ventilation duct frame). If there are matching protrusions or blocks on the external frame, the connecting groove 19 on the connecting plate 17 can be aligned with these structures, and they can be made to cooperate by pushing or inserting to achieve initial positioning and connection. If the external frame is provided with installation positions for bolts or other connectors, the connecting hole 18 of the connecting plate 17 is aligned with the corresponding hole in the external frame to prepare for subsequent installation of fasteners.

[0077] The connecting plate 17 can be first fitted to the outer frame, and then the connecting holes 18 and connecting grooves 19 are connected to increase the connection area between the frame 14 and the outer frame. During daily use of the blinds, the connecting parts are continuously subjected to stress due to external forces such as wind and vibration. The connecting plate 17 is tightly connected to the outer frame through the connecting grooves 19 and / or connecting holes 18, allowing external forces to be effectively transferred from the support frame 10 to the outer frame.

[0078] Therefore, the connection groove 19 and connection hole 18 enable the connection plate 17 to adapt to different types of external frame connection structures, increasing the flexibility of the connection. Simultaneously, the connection part can evenly transmit external forces to the external frame, achieving force dispersion. In this way, excessive localized stress is avoided, preventing damage to the connection plate 17 or the external frame, ensuring the stability of the entire structure under complex stress environments, extending the service life of each component, and ensuring that the louvers can function continuously and stably under various working conditions.

[0079] In addition, the connecting plate 17 can also be provided with a hook 20. Correspondingly, the outer frame is provided with a slot that cooperates with the hook 20. In this way, the frame 14 can be hooked and engaged with the outer frame through the hook 20. Through the engagement of the hook 20 and the weight of the frame 14 itself, the frame 14 can be firmly connected to the outer frame.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
