Description

Technical Field

[0001] This utility model relates to the cross-application field of building technology and mechanical manufacturing, and in particular to an aluminum alloy venetian blind. Background Technology

[0002] Aluminum alloy venetian blinds are architectural shading devices made primarily of aluminum alloy, consisting of multiple adjustable slats and a matching lifting / tilting mechanism. Their core function is to control light, ventilation, and privacy through slat angle adjustment, while also offering some decorative appeal. They are widely used in window shading applications in various buildings such as residences, offices, and hotels. Soundproofing is crucial because the aluminum alloy slats themselves are relatively thin and transparent, resulting in limited sound insulation. However, in practical applications (such as street-facing buildings and busy office areas), users have a high demand for a quiet indoor environment. By optimizing the slat structure (e.g., using a hollow design or adding sound-absorbing materials) or combining sound-insulating modules, their ability to block external noise can be effectively enhanced, improving the comfort of living or working environments.

[0003] Existing patent CN217129390U discloses an aluminum alloy Venetian blind, comprising: a drive box, the drive box having an adjustment device for the Venetian blind; a Venetian blind body, the Venetian blind body including several sets of adjustment ropes and several sets of venetian blinds, the venetian blinds being detachably mounted on the adjustment ropes, the upper ends of the adjustment ropes being connected to the adjustment device for the Venetian blind; and a base plate, the upper end of the base plate being connected to the lower ends of the adjustment ropes. Its key technical features are that the venetian blinds are easy to assemble and disassemble, easy to maintain, reusable, and have good performance. They reduce light transmission, have high light-blocking effect, and allow air to move along the slope, blowing away dust on the slope, extending the cleaning interval of the venetian blinds, reducing the number of cleanings, thus effectively reducing the workload of operators. The good performance and promising future applications are significant advantages.

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: this structure provides sufficient light blocking as an outdoor venetian blind, but does not take into account the impact of noise on the indoor environment.

[0005] Therefore, those skilled in the art have provided an aluminum alloy venetian blind to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an aluminum alloy Venetian blind with a simple and compact structure and low manufacturing cost. The main blades are equipped with telescopic rods, and the surface of the telescopic rods is provided with teeth. The teeth work with the internal gears to control the opening and closing of the blades. When the Venetian blind is lowered, the blades retract and stand up to lower the sound insulation cotton in the secondary compartment that is fixed to the surface, thus isolating light and sound from the room. Conversely, when the Venetian blind is pulled up, the blades extend and roll to the top to allow as much light as possible into the room.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy venetian blind, including a roller blind stretching mechanism, wherein a roller blind body is provided inside the roller blind stretching mechanism, and a sound-insulating secondary curtain is fixedly provided on the surface of the roller blind body.

[0008] Furthermore, the roller shutter stretching mechanism includes a housing body, a threaded rod fixedly connected to one side surface of the housing body, an installation groove fixedly provided on the upper surface of the housing body, a solar photovoltaic power generation panel fixedly provided inside the installation groove, and an adapter cable fixedly connected to one side surface of the solar photovoltaic power generation panel.

[0009] Furthermore, a motor is fixedly connected to the surface of the adapter cable, a rotating shaft is fixedly connected to the output end of the motor, and a lifting belt is connected to the surface of the rotating shaft.

[0010] Furthermore, a guide plate is fixedly installed inside the main body of the cover, a fixing rod is fixedly connected to the lower surface of the guide plate, and a bottom rail is fixedly connected to the lower surface of the fixing rod.

[0011] Furthermore, the main body of the roller blind includes blades, and gears are rotatably arranged inside the blades.

[0012] Furthermore, a telescopic rod is fixedly connected to one side surface of the blade, a tooth is fixedly connected to the surface of the telescopic rod, and a secondary blade is fixedly connected to the surface of the tooth.

[0013] Furthermore, the soundproof secondary curtain includes a secondary curtain shell, a secondary curtain compartment is fixedly disposed inside the secondary curtain shell, sliders are fixedly disposed on both sides of the inner side of the secondary curtain compartment, a tension rod is fixedly connected to the inner side of the secondary curtain compartment, sound insulation cotton is fixedly connected to the surface of the tension rod, and grooves are fixedly disposed on both sides of the sound insulation cotton.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes an aluminum alloy Venetian blind with a sound-insulating secondary curtain on the surface of the main body of the roller blind. When the Venetian blind is closed, the secondary curtain falls down together and fits tightly against the seam, effectively enhancing the sound insulation performance of the Venetian blind and meeting the needs of users for a quiet indoor environment in scenarios such as street-facing buildings and busy office areas. The solar photovoltaic power generation panel on the upper surface of the cover in the roller blind's stretching mechanism enables green power supply to the motor, reducing energy consumption and saving energy.

[0015] 2. The aluminum alloy venetian blind proposed in this utility model has a telescopic rod and gear structure inside the blades, which allows the blades to expand and contract when the whole blind is pulled down and raised. This makes it convenient for users to adjust the light and ventilation according to actual needs and saves installation space. The synergistic effect of the secondary curtain box, slider, tension rod and sound insulation cotton component in the sound insulation secondary curtain ensures that the sound insulation cotton can be stably lowered when the venetian blind is fully closed, effectively blocking external noise and creating a quieter indoor environment for users.

Detailed Implementation

[0018] 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.

[0019] refer to Figure 1 One embodiment of this utility model is an aluminum alloy venetian blind, which includes a roller blind stretching mechanism 1, a roller blind body 2 is provided inside the roller blind stretching mechanism 1, and a sound insulation secondary curtain 3 is fixedly provided on the surface of the roller blind body 2.

[0020] Specifically, the roller blind stretching mechanism 1 is a component that realizes the lifting and lowering function of the Venetian blind. It is equipped with the roller blind body 2 inside. The overall curtain body’s opening and closing action is controlled by a mechanical transmission structure (motor 106, rotating shaft 107). The roller blind body 2 is the main light-blocking structure of the Venetian blind, which is composed of multiple sets of retractable blades 201. The isolation of light and sound sources is achieved by changing the angle and extension state of the blades 201. The sound insulation secondary curtain 3 is an auxiliary structure that improves the sound insulation performance of the device. It operates in conjunction with the roller blind body 2 and unfolds to form a sealed barrier when the curtain is closed.

[0021] refer to Figure 1-6 The roller shutter stretching mechanism 1 includes a housing body 101, a threaded rod 102 fixedly connected to one side surface of the housing body 101, an installation groove 103 fixedly provided on the upper surface of the housing body 101, a solar photovoltaic power generation panel 104 fixedly provided inside the installation groove 103, and an adapter cable 105 fixedly connected to one side surface of the solar photovoltaic power generation panel 104.

[0022] Specifically, the main body 101 serves as the outer shell structure of the roller shutter stretching mechanism 1, accommodating its internal components and achieving fixed installation with the building structure through the surface threaded rod 102. The mounting groove 103 on its upper surface provides a stable mounting position for the solar photovoltaic power generation panel 104. The electrical energy generated by the photovoltaic panel is transmitted to the motor 106 through the adapter cable 105, forming an independent green power supply system and saving energy consumption.

[0023] refer to Figure 1-6 A motor 106 is fixedly connected to the surface of the adapter cable 105, a rotating shaft 107 is fixedly connected to the output end of the motor 106, and a lifting belt 108 is connected to the surface of the rotating shaft 107.

[0024] Specifically, the motor 106 serves as the power core of the roller blind stretching mechanism 1. It starts to operate by receiving electrical energy transmitted from the solar photovoltaic power generation panel 104. The rotating shaft 107 connected to its output end rotates synchronously with the motor 106. The rotating shaft 107 has a groove on its surface. The lifting belt 108 wound around the groove produces a lifting or lowering action during rotation, directly controlling the lifting and lowering movement of the roller blind body 2, thereby realizing the opening and closing function of the Venetian blind.

[0025] refer to Figure 1-6 A guide plate 109 is fixedly installed inside the main body 101 of the cover. A fixing rod 110 is fixedly connected to the lower surface of the guide plate 109. A bottom rail 111 is fixedly connected to the lower surface of the fixing rod 110.

[0026] Specifically, the guide plate 109 is horizontally arranged inside the main body 101 of the housing. Its function is to provide a guiding path for the movement of the lifting belt 108, ensuring that the lifting belt 108 maintains a stable trajectory during transmission and avoiding deviation or entanglement. The fixing rod 110 serves as a connector between the guide plate 109 and the bottom rail 111. Through a rigid structure, it transmits the supporting force of the guide plate 109 to the bottom rail 111. The bottom rail 111 is fixed to the lower edge of the building window, providing a limit and support for the bottom of the roller blind body 2. When the roller blind body 2 descends to the lowest point, the bottom rail 111 prevents the curtain from falling further by contacting the building structure. At the same time, it forms a closed space with the main body 101 of the housing, enhancing the sound insulation effect.

[0027] refer to Figure 1-6 The main body 2 of the roller shutter includes blades 201, and a gear 202 is rotatably arranged inside the blades 201.

[0028] Specifically, the blade 201, as the core component of the roller blind body 2, is made of aluminum alloy. The gear 202 inside is fixed to the blade 201 frame through a shaft and is passed through by the lifting belt 108. The gear 202 can rotate around the axis. When the roller blind stretching mechanism 1 drives the blade 201 to move through the lifting belt 108, the gear 202 and the subsequent components will realize the unfolding and retracting action of the blade 201.

[0029] refer to Figure 1-6 A telescopic rod 203 is fixedly connected to one side surface of the blade 201, a tooth 204 is fixedly connected to the surface of the telescopic rod 203, and an auxiliary blade 205 is fixedly connected to the surface of the tooth 204.

[0030] Specifically, the telescopic rod 203 adopts a telescopic structure, with one end fixed to the side wall of the blade 201 and the other end connected to the secondary blade 205 through the tooth 204. The tooth 204 is a regularly arranged tooth structure that meshes with the gear 202 for transmission. When the roller blind stretching mechanism 1 drives the blade 201 to rise and fall, the gear 202 drives the tooth 204 to move by rotating, thereby controlling the extension and retraction length of the telescopic rod 203 and realizing the expansion or retraction of the secondary blade 205. When the blind is lowered to the closed state, the secondary blade 205 and the main blade 201 form an overlapping structure to enhance the light blocking and sound insulation effect. When the blind is raised to the open state, the secondary blade 205 unfolds to allow light to pass through as much as possible.

[0031] refer to Figure 1-6 The soundproof secondary curtain 3 includes a secondary curtain housing 301, a secondary curtain compartment 302 fixedly installed inside the secondary curtain housing 301, sliders 303 fixedly installed on both sides of the inner surface of the secondary curtain compartment 302, a tension rod 304 fixedly connected to the inner surface of the secondary curtain compartment 302, sound insulation cotton 305 fixedly connected to the surface of the tension rod 304, and grooves 306 fixedly installed on both sides of the sound insulation cotton 305.

[0032] Specifically, the secondary curtain shell 301, as the external protective structure of the sound-insulating secondary curtain 3, is made of aluminum alloy, which can effectively prevent external factors from damaging the internal components. The secondary curtain compartment 302 inside provides storage space for the sound-insulating cotton 305. When the Venetian blind is open, the sound-insulating cotton 305 can be stored in the secondary curtain compartment 302 to avoid occupying extra space. The sliders 303 fixed on both sides of the inner side of the secondary curtain compartment 302 cooperate with the sliding grooves 306 on both sides of the sound-insulating cotton 305 to form a sliding connection structure, ensuring that the sound-insulating cotton 305 can be stretched during the process. The system operates smoothly without any jamming or shifting. The tension rod 304, as a key component connecting the secondary curtain chamber 302 and the sound insulation cotton 305, transmits the tension force to the sound insulation cotton 305 through a rigid structure. When the Venetian blind descends to the closed state, the sound insulation cotton 305 slides out through the sliding structure due to its own weight, making it stick tightly to the surface of the roller blind body 2, forming a sealed sound barrier that effectively blocks the transmission of external noise. When the Venetian blind rises to the open state, the tension rod 304 drives the sound insulation cotton 305 to retract back into the secondary curtain chamber 302, realizing the automatic storage of the sound insulation cotton 305.

[0033] Working principle: When using the Venetian blinds, the motor 106 is started. The motor 106 receives electrical energy transmitted from the solar photovoltaic panel 104 through the adapter cable 105 and begins to operate. The rotating shaft 107 connected to its output end rotates synchronously with the motor 106. The lifting belt 108 wound on the surface of the rotating shaft 107 generates a downward movement during rotation, driving the main body of the blind 2 to descend. The lifting belt 108 can be manually operated. During the descent of the main body of the blind 2, the gear 202 rotates with the movement of the lifting belt 108, driving the meshing gear 204 to move through meshing transmission, thereby controlling the extension of the telescopic rod 203 and causing the secondary blades 205 to retract. When the main body of the blind 2 descends to the lowest point, the bottom rail 111 contacts the building structure to prevent the blind from falling further. The sound insulation cotton 305 slides out of the secondary curtain compartment due to its own weight through the sliding connection structure between the slider 303 and the slide groove 306. 302, closely attached to the surface of the roller blind body 2, forms a sealed sound barrier, effectively blocking the entry of external noise. At this time, the blind is in a fully closed state, which can meet the user's needs for indoor shading and a quiet environment. When the blind needs to be opened, the motor 106 is started, the rotating shaft 107 rotates in the opposite direction, the lifting belt 108 produces a lifting action, driving the roller blind body 2 to rise. The gear 202 rotates in the opposite direction to drive the meshing tooth 204 to move, controlling the extension rod 203 to extend, so that the secondary blades 205 unfold. At the same time, the extension rod 304 lifts the sound insulation cotton 305 upward as the roller blind body 2 rises. The sound insulation cotton 305 retracts back into the secondary curtain chamber 302 through the sliding connection structure between the slider 303 and the slide groove 306, realizing the automatic storage of the sound insulation cotton 305. When the roller blind body 2 rises to the highest point, the blind is in a fully open state, allowing light to enter the room as much as possible.

[0034] 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.
