Description

Technical Field

[0001] This utility model relates to the field of louver technology, specifically to a low-resistance single-handle louver. Background Technology

[0002] Venetian blinds are a common architectural shading and privacy protection device that controls light entry and visual obstruction by adjusting the angle of the slats.

[0003] Traditional Venetian blinds typically use a ladder rope and pull rope system to control the raising, lowering, and tilting of the slats. In this system, the user needs to operate the raising and lowering pull rope and the tilting pull rope separately to complete two different actions, which is relatively cumbersome. Existing technology has made many improvements to Venetian blinds. For example, Chinese patent CN208137816U discloses a Venetian blind that includes multiple slats, vertical posts arranged on the sides of the multiple slats, a pull rod, and multiple toothed caps. The pull rod is slidably embedded in the vertical post and engages with one end of the multiple toothed caps. The other end of the multiple toothed caps passes through the vertical post and is respectively inserted into the multiple slats. Rotating the slats causes the corresponding toothed caps to rotate, and the pull rod slides in the vertical post, thereby causing the multiple slats to rotate and be able to stop.

[0004] However, the following shortcomings still exist in practical applications: 1. The entire transmission system relies on the precise meshing of the rack and pinion on the tie rod with multiple toothed caps. This is costly and prone to wear and tear over long periods of use, eventually rendering the system unusable. 2. The installation of the entire equipment is rather complicated, and its adaptability and versatility are poor.

[0005] Based on this, the present invention designs a low-resistance single-handle louver to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a low-resistance single-handle louver.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A low-resistance single-handle Venetian blind includes a fixed bracket, an integrated moving mechanism for turning and lifting the blind, and a Venetian blind. It also includes a magnetic drive mechanism. The fixed bracket is connected to the integrated moving mechanism for turning and lifting the blind. The magnetic drive mechanism is installed on the glass. The glass is connected to the fixed bracket. The Venetian blind is connected to the integrated moving mechanism for turning and lifting the blind. The integrated moving mechanism for turning and lifting Venetian blinds includes a rotating component, a turning component, a lifting component, a single-handle drive component, and a self-tensioning component. Two sets of turning components are symmetrically distributed on the left and right. The rotating component is connected to the self-tensioning component. The turning component for controlling the turning of the Venetian blinds is connected to the rotating component and the Venetian blinds respectively. The lifting component for controlling the lifting of the Venetian blinds is connected to the rotating component and the turning component respectively. The single-handle drive component for driving the turning and lifting of the Venetian blinds is connected to the rotating component and the lifting component.

[0010] Furthermore, the page-turning assembly includes a page-turning fixing block, a page-turning rotating block, and a page-turning traction rope. The page-turning fixing block is located inside the rotating fixing block and is fixedly connected to the upper end of the upper support base plate.

The central rotating shaft is fixedly connected to the page-turning rotating block.

[0011] Furthermore, the lifting assembly includes a lifting traction rope and a lifting fixing block. Two sets of left and right symmetrical lifting fixing blocks are fixedly connected to the left bracket and the right bracket respectively. The venetian blind is provided with two sets of left and right symmetrically distributed lifting traction rope avoidance holes for avoiding the lifting traction rope.

[0012] Furthermore, the single-handle drive assembly includes a single-handle drive block, a single-handle magnetic block, and a single-handle wheel. Two sets of single-handle wheels, symmetrically distributed vertically, are rotatably connected to the single-handle drive block. The single-handle wheels are used to reduce the friction when the single-handle drive block moves up and down. Two sets of single-handle magnetic blocks, symmetrically distributed vertically, are fixedly connected to the front end of the single-handle drive block. The single-handle wheel is located outside the single-handle magnetic block. The front end of the rotating traction rope passes through the single-handle drive block and is fixedly connected inside the single-handle drive block. One end of the lifting traction rope is fixedly connected to the lower end of the lifting fixed block located on the right. The lifting traction rope passes in sequence through the single-handle rotating wheel, the lifting fixed block located on the right, the rotating fixed block located on the right, the flipping fixed block located on the right, the flipping fixed block located on the left, the lifting traction rope clearance hole located on the left, the lifting traction rope clearance hole located on the right, and the flipping fixed block located on the right. Finally, the other end of the lifting traction rope is fixedly connected to the outer wall of the rotating fixed block located on the right.

[0013] Furthermore, the self-tensioning assembly includes a tensioning fixed block, a tensioning movable block, a tensioning movable column, a tensioning spring, and a tensioning wheel.

[0014] Furthermore, the mounting side panel has a hollow structure, with a plug-in block fixedly connected to one end. The left and right brackets have plug-in slots for plugging into the plug-in block. The upper end of the mounting side panel has a mounting groove on the same side as the plug-in block. The mounting side panel can be connected to the plug-in groove on the left or right bracket through the plug-in block. When the two sets of mounting side panels are installed on the left and right brackets, the mounting front panel can be plugged into the mounting groove.

[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. When the magnetic drive block is moved, the Venetian blind will first turn the page and then rise and fall. When the Venetian blind has finished turning the page, the page turning block will rotate freely and will not affect the rising and falling process. Thus, through the cooperation of the magnetic drive block and the single handle drive block, the page turning and rising and falling operations can be completed by a single handle drive, which is convenient to operate. 2. Since the lifting traction rope is a single line, its connection method is that one end of the lifting traction rope is fixedly connected to the lower end of the lifting fixed block. The lifting traction rope sequentially winds around the single-handle rotating wheel, the lifting fixed block on the right, the rotating fixed block on the right, the flip-page fixed block on the right, the rotating fixed block on the left, the lifting traction rope clearance hole on the left, the venetian blind on the right, and the flip-page fixed block on the right, and finally the other end of the lifting traction rope is fixedly connected to the outer wall of the rotating fixed block on the right. Therefore, it can be ensured that when the venetian blind is raised and lowered, each group of blades rises and falls horizontally at the same height without tilting or shifting. At the same time, compared with the existing technology that uses two strands of wire to be knotted at the bottom, the operating resistance is smaller and the operation is smoother and more fluid. 3. During the page-turning process, the tension spring always provides a certain downward elastic force to the tension moving column and the tension moving block, so that the tensioning wheel can keep the page-turning traction rope taut, ensuring the stability of the page-turning process; 4. The installation method between the fixed bracket, mounting side plate, mounting front plate and magnetic drive mechanism is simple and reliable. Attached Figure Description

[0031] The single-handle drive assembly 24 includes a single-handle drive block 241, a single-handle magnetic block 242, and a single-handle rotating wheel 243. Two sets of single-handle rotating wheels 243, which are symmetrically distributed vertically, are rotatably connected to the single-handle drive block 241.

[0035] like Figure 5 As shown, the mounting side plate 3 is a hollow structure. One end of the mounting side plate 3 is fixedly connected to a plug-in block 32. The left bracket 14 and the right bracket 15 are provided with plug-in slots 33 for plugging into the plug-in block 32. The upper end of the mounting side plate 3 is also provided with a mounting slot 31 on the same side as the plug-in block 32. The mounting side plate 3 can be connected to the plug-in slot 33 on the left bracket 14 or the right bracket 15 through the plug-in block 32. When the two sets of mounting side plates 3 are installed on the left bracket 14 and the right bracket 15, the mounting front plate 4 can be plugged into the mounting slot 31.

[0036] The front panel 4 is made of a soft plastic material.

[0037] like Figure 6 As shown, the magnetic drive mechanism 5 includes a magnetic drive block 51, a limiting block 52, and a mounting strip 53. The rear end of the mounting strip 53 is fixedly connected to the front end of the glass 7. The magnetic drive block 51 is slidably connected to the mounting strip 53. Two sets of symmetrically distributed limiting blocks 52 are fixedly connected to the magnetic drive block 51. The limiting blocks 52 are used to limit the maximum movement distance of the magnetic drive block 51. The rear end of the glass 7 is fixedly connected to the mounting side plate 3, the upper bracket 11, and the lower bracket 12.

[0038] Both the magnetic drive block 51 and the single-handle drive block 241 are equipped with strong magnets. Under the action of the strong magnets, the magnetic drive block 51 and the single-handle drive block 241 can attract each other and move together.

[0039] In this utility model, when installing the low-resistance single-handle venetian blind, first install the venetian blind 6, the upper bracket 11, and the venetian blind flip-up and lifting integrated moving mechanism 2. Then, install the lower bracket 12 on the left bracket 14 and the right bracket 15 through the limiting mounting block 13. Next, install the plug block 32 in the mounting groove 31 so that the mounting side plate 3 is installed on the left bracket 14 and the right bracket 15. Then, insert the mounting front plate 4 into the mounting groove 31 to cover the structure at the upper bracket 11 for aesthetic purposes. Then, install the glass 7 at the front end of the upper bracket 11, the lower bracket 12, the left bracket 14, and the right bracket 15. Finally, install the mounting strip 53 on the right side of the front end of the glass 7. The position of the mounting strip 53 corresponds to the position of the single-handle drive assembly 24, and the position of the magnetic drive block 51 corresponds to the position of the single-handle drive block 241. When adjusting the louvers of the Venetian blind 6, only a slight movement of the magnetic drive block 51 is needed. The movement of the magnetic drive block 51 will cause the single-handle drive block 241 to move synchronously. With the cooperation of the rotating traction rope 213, the up-and-down movement of the single-handle drive block 241 will cause the central rotating shaft 214 and rotating column 212 on the rotating fixed block 211 to rotate. The rotation of the central rotating shaft 214 will cause the louvering rotating block 222 on the louvering fixed block 221 to rotate. Under the action of the louvering traction rope 223, the rotation of the louvering rotating block 222 will cause the Venetian blind 6 to louver. If the single-handle drive block 241 is moved further, with the cooperation of the lifting traction rope 231, the Venetian blind 6 will move up and down synchronously in the opposite direction to raise and lower. That is, when the single-handle drive block 241 descends, the Venetian blind 6 will rise, and when the single-handle drive block 241 rises, the Venetian blind 6 will descend. The two sets of limit blocks 52 are used to limit the maximum movement distance of the magnetic drive block 51. During the page turning process, the tension spring 254 always provides a certain downward elastic force to the tension moving column 253 and the tension moving block 252, so that the tensioning wheel 255 can always keep the page turning traction rope 223 taut, ensuring the stability of the page turning process. When the magnetic drive block 51 is moved, the Venetian blind 6 will first flip the page and then rise and fall. When the Venetian blind 6 has finished flipping the page, the flipping rotating block 222 will spin freely and will not affect the rising and falling process. Thus, through the cooperation of the magnetic drive block 51 and the single handle drive block 241, the page flipping and rising and falling operations can be completed by a single handle drive, which is convenient to operate. Meanwhile, since the lifting traction rope 231 is a single line, its connection method is that one end of the lifting traction rope 231 is fixedly connected to the lower end of the lifting fixing block 232. The lifting traction rope 231 sequentially winds around the single-handle rotating wheel 243, the lifting fixing block 232 located at the right end, the rotating fixing block 211 located at the right end, the flip-page fixing block 221 located at the right end, the rotating fixing block 211 located at the left end, the lifting traction rope clearance hole 61 located at the left end, the Venetian blind 6 located at the right end, and the flip-page fixing block 221 located at the right end. Finally, the other end of the lifting traction rope 231 is fixedly connected to the outer wall of the rotating fixing block 211 located at the right end. Therefore, it can be ensured that when the Venetian blind 6 is raised and lowered, each group of blades is raised and lowered horizontally at the same height without tilting or shifting. At the same time, compared with the existing technology that uses two strands of wire to be knotted at the bottom, the operating resistance is smaller and the operation is smoother.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
