Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to a blind frame and a blind assembly. Background Art

[0002] Venetian blinds are window coverings consisting of multiple parallel blades, mainly used to control indoor light, ventilation and privacy. Common blinds on the market currently include products made of plastic, wood and metal. Although these traditional blinds have the basic functions of sunshade and heat insulation, they have problems such as inconvenient angle adjustment and poor wind pressure resistance during actual use. As people's requirements for indoor environmental comfort continue to increase, traditional blinds can no longer meet the needs of modern architectural design.

[0003] Currently, two common approaches to address this issue are: increasing blade thickness to improve overall rigidity and deformation resistance; and introducing an electric control system for automatic opening and closing. However, the former increases costs and inconveniences maintenance; while the latter, while more convenient, increases the risk of failure due to electronic components being susceptible to external interference.

[0004] The current shutter design solutions on the market ignore the importance of the frame structure and cannot effectively ensure long-term stable operation under severe weather conditions. In addition, while pursuing beautiful appearance, certain functional practicality is often sacrificed. Therefore, a shutter frame and shutter assembly are proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a shutter frame and a shutter assembly, aiming to improve the problem that the existing technology ignores the importance of the frame structure and cannot effectively ensure long-term stable operation under severe weather conditions.

[0007] Through the above technical solution: the slots on the left and right ends of the blades facilitate the quick installation of the blades on the frame, improve the installation efficiency, reduce the installation time and labor costs, and the multiple reinforcing ribs on the inside of the blades enhance the strength and rigidity of the blades, making the blades not easy to deform during use. Even when encountering external forces such as strong winds, they can maintain their original shape, thereby improving the stability and durability of the blinds. Multiple blades are connected by a linkage rod, so that the angles of multiple blades can be adjusted at the same time by pulling the pull rope. The operation is convenient and quick, which improves the convenience of user use.

[0008] As a further description of the above technical solution:

[0009] The limiting mechanism includes a rotating shaft, the left end of the rotating shaft is fixedly connected to the right end of the linkage rod, the right end of the rotating shaft is fixedly connected to a cross column, the inner side of the frame is slidably connected to a fixed column, a cross groove is opened on the left side of the fixed column, the outer wall of the cross column is slidably connected to the inner side of the cross groove, and the right side of the fixed column is fixedly connected to a push rod.

[0010] Through the above technical solution: the cross column is slidably connected to the cross groove on the left side of the fixed column. When multiple blades are rotated to the appropriate angle, precise positioning can be achieved to ensure the consistency of the blade angle and prevent the distance between the blades from being too wide or too narrow, thereby ensuring the best ventilation effect and neat visual beauty. After the blade angle is determined, this connection method can effectively limit the further rotation of the shaft, thereby maintaining the stability of the blade angle, which is not easy to change even if affected by external forces.

[0014] As a further description of the above technical solution:

[0015] The bottom of the pull rope is fixedly connected to a handle, and the outer wall of the handle is made of silicone material.

[0016] Through the above technical solution: the outer wall of the handle is made of silicone material, which has good anti-slip performance, so that when pulling the pull rope to adjust the blade angle, the hand is not easy to slip, and the operation is safer and more reliable.

[0017] As a further description of the above technical solution:

[0025] Through the above technical solution: the blade cross-section is L-shaped, which increases the structural strength of the blade; the outer wall of the blade is covered with a waterproof coating, which effectively prevents moisture from penetrating into the interior of the blade, avoiding damage and corrosion to the blade caused by moisture erosion, and further improving the durability and reliability of the blinds.

[0026] As a further description of the above technical solution:

[0027] The blades are made of aluminum alloy material.

The inner sides of the multiple blades 1 are fixedly connected with linkage rods 4, so that the blades 1 can be linked to each other. The outer walls of the multiple linkage rods 4 are slidably connected with pull ropes 6, and the angles of the multiple blades 1 can be adjusted at the same time by pulling the pull ropes 6, which is convenient and quick to operate, and improves the convenience of use of the shutter. The inner sides of the blades 1 are fixedly connected with multiple reinforcing ribs 5, which greatly enhance the rigidity of the blades 1, making the overall structure more stable and not easy to deform. Even in the event of strong wind, it can maintain its original shape, ensuring the stability and reliability of the shutter. The outer sides of the blades 1 are fixedly connected with linkage rods 4, so that the blades 1 can be linked to each other. The wall is provided with a frame 8, which provides support and protection for the blades 1 and other components. A limiting mechanism 2 is provided on the inner side of the frame 8, which can ensure that the spacing between adjacent blades 1 is uniform and consistent, preventing the distance between the blades 1 from being too wide or too narrow, thereby ensuring the best ventilation effect and neat visual beauty; the bottom of the pull rope 6 is fixedly connected with a handle 7, and the outer wall of the handle 7 is made of silicone material, which increases the comfort of operation; the reinforcing rib 5 is made of high-carbon steel wire; the cross-section of the blade 1 is L-shaped, and the outer wall of the blade 1 is covered with a waterproof coating, which effectively prevents moisture from penetrating into the inside of the blade 1, avoids corrosion and damage caused by moisture, and extends the service life of the blinds; the blade 1 is made of aluminum alloy material, which has the advantages of light weight and high strength, is easy to install and transport, and can withstand a certain amount of external force without being easily damaged;

[0041] Specifically, the blade 1 is made of high-strength aluminum alloy, using 6063-T5 series aluminum alloy material, with reinforcing ribs 5 embedded inside to enhance its rigidity. The cross-section of the blade 1 is L-shaped, and the outside is covered with a waterproof coating to effectively prevent moisture from penetrating into the inside of the blade 1, avoiding corrosion and damage caused by moisture, and extending the service life of the blinds. Special card slots 3 are provided at both ends for quick installation of the blades 1, and the inner sides of multiple blades 1 are fixedly connected to the linkage rod 4. Multiple blades 1 and the frame 8 constitute the entire blind assembly. The angle of the blade 1 can be adjusted by simply pulling, which is convenient and quick to operate, thereby improving the convenience of use of the blinds. The pull rope 6 can be replaced with a stainless steel wire rope to further improve the service life.

[0042] Refer to the attached Figure 1 and attached Figure 5The limiting mechanism 2 includes a rotating shaft 201, the left end of the rotating shaft 201 is fixedly connected to the right end of the linkage rod 4, the right end of the rotating shaft 201 is fixedly connected to a cross column 202, the inner side of the frame 8 is slidably connected to a fixed column 203, and a cross groove 204 is provided on the left side of the fixed column 203. The outer wall of the cross column 202 is slidably connected to the inner side of the cross groove 204, and the cross column 202 can be accurately fitted in the cross groove 204, and only when multiple blades 1 rotate the same degree can they be accurately engaged in the cross groove 204, ensuring that each The consistency of the rotation angles between the blades 1 prevents the distance between the blades 1 from being too wide or too narrow, thereby ensuring the best ventilation effect and neat visual beauty. The right side of the fixed column 203 is fixedly connected to the push rod 205; the right side of the push rod 205 is fixedly connected to the push handle 206. The outer wall of the push rod 205 is slidably connected to the inner side of the frame 8. The fixed column 203 and the push rod 205 slidably connected to the inner side of the frame 8, as well as the connection between the cross column 202 and the cross slot 204, together limit the consistency and stability of the rotation angle of the blade 1.

[0043] Specifically, through the fixed connection between the rotating shaft 201 and the linkage rod 4, it is ensured that the rotation of the linkage rod 4 can be accurately transmitted to the rotating shaft 201, thereby realizing effective transmission of power. The matching design of the cross column 202 and the cross slot 204 enables accurate alignment and connection when multiple blades 1 rotate to the same angle, ensuring the consistency of the angle of the blades 1 and preventing the distance between the blades 1 from being too wide or too narrow, thereby ensuring the best ventilation effect and neat visual beauty.

At the same time, the components of the limiting mechanism 2 are injection molded from polyformaldehyde POM plastic, which has good wear resistance and self-lubricating properties.

[0044] Refer to the attached Figure 1 , the left side of the outer wall of the linkage rod 4 is rotatably connected to the left side of the inner wall of the frame 8;

[0045] Specifically, the outer wall of the linkage rod 4 is rotatably connected to the inner side of the frame 8, so that the linkage rod 4 and the frame 8 can be tightly combined together, thereby enhancing the structural integrity of the shutter assembly.

[0046] Working principle: The blade 1 is made of aluminum alloy, which has high strength and good corrosion resistance. The cross section of the blade 1 is L-shaped, and a slot 3 is opened on its left and right ends. During installation, the slot 3 is matched with the corresponding structure of other components to complete the installation of the blinds. A plurality of reinforcing ribs 5 are set inside the blade 1. They are made of high-carbon steel wire with a diameter of two millimeters and the length can be customized according to the size of the frame bar, which enhances the rigidity of the blade 1. When the user needs to adjust the angle of the blinds, he only needs to use the handle 7 to gently pull the pull rope 6 on one side to drive the internal linkage rod 4 to rotate, thereby causing the blade 1 to tilt along the set trajectory, and the rotation of the linkage rod 4 will drive the rotating shaft 201 to rotate synchronously. When the rotating shaft 201 rotates, the cross column 202 fixed to its right end also rotates accordingly. When multiple blades 1 rotate to the same angle, the push rod 205 can be pushed to align the cross slot 204 on the fixing column 203 with the cross column 202 on the rotating shaft 201, so that the rotation angle is consistent, limiting the further rotation of the rotating shaft 201 and preventing the distance between the blades 1 from being too wide or too narrow.
