Description

Technical Field

[0001] This utility model relates to the technical field of Venetian blind equipment, specifically a Venetian blind with a blind angle control device. Background Technology

[0002] Venetian blinds are a common type of curtain, made up of many horizontal or vertical thin slats. They can block the view from outside to a certain extent, protect indoor privacy, and allow air to circulate freely between the inside and outside, keeping the air fresh. In addition, their simple design has a certain decorative effect and can be matched with a variety of decoration styles.

[0003] Venetian blinds achieve different functions by adjusting the angle of the slats. Their main functions include flexibly adjusting the intensity of light entering the room according to needs, achieving full blackout, partial blackout, and other effects. However, in daily use, the slats of existing Venetian blinds are often prone to bending or deformation due to their thinness. This not only affects the aesthetics of the Venetian blinds but also makes the gaps between the slats uneven, thereby reducing the blackout and privacy protection effects. Utility Model Content

[0004] The purpose of this utility model is to provide a Venetian blind with a shading control device to solve the problem that the slats of existing Venetian blinds are often bent or deformed due to their thinness during daily use. This not only affects the aesthetics of the Venetian blinds, but also makes the gaps between the slats uneven, thereby reducing the light blocking and privacy protection effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Venetian blind with a shading control device, comprising: a side frame, a stepper motor fixedly connected to one end of the outer side of the side frame, a gear fixedly connected to the output end of the stepper motor, a limiting plate fixedly connected to one end of the back side of the side frame, a quick-connect mechanism provided on one side of the inside of the side frame, a driven mechanism provided on the other side of the inside of the side frame, a thin blade provided between the quick-connect mechanism and the driven mechanism, a slide bar slidably connected to the front of the limiting plate, a toothed block fixedly connected to the front of the slide bar, and a toothed block two fixedly connected to the back of the slide bar.

[0006] As a further embodiment of this utility model: an upper mounting rail is movably inserted into the top of the side frame, and a lower mounting rail is movably inserted into the bottom of the side frame. One end of the upper mounting rail is provided with a mounting hole, and one end of the lower mounting rail is also provided with a mounting hole structure.

[0007] As a further embodiment of this utility model: the quick-connect mechanism includes a fixed column, a spring, and a movable block. The fixed column is fixedly connected to one side of the side frame, the spring is fixedly connected to the inside of the fixed column, and the movable block is movably inserted into the fixed column; there is also a rotating block and a first insert block. The rotating block is rotatably connected to one end of the movable block, the first insert block is inserted into the rotating block, and the other end of the first insert block is engaged with the thin blade.

[0008] As a further embodiment of this utility model: the driven mechanism includes a rotating column, a second gear, and a second insert block. The rotating column is rotatably connected to the other side of the side frame. The second gear is fixedly connected to one end of the outer side of the rotating column. The second insert block is inserted into the rotating column. The other end of the second insert block is engaged with a thin blade. The second gear meshes with the first gear block.

[0009] As a further embodiment of this utility model: the first gear meshes with the second gear block, the first gear block is provided in multiple sets and is symmetrically arranged on the front side of the slide bar, and the back side of the slide bar is provided with several sets of the second gear blocks.

[0010] As a further embodiment of this utility model: multiple sets of the quick-connect mechanism, the driven mechanism, and the thin blade are provided. Multiple sets of the quick-connect mechanism are arranged vertically and symmetrically on one side inside the side frame, and multiple sets of the driven mechanism are arranged vertically and symmetrically on the other side inside the side frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, after the stepper motor starts, it drives the rotating column through the cooperation of components such as gear one, gear two, slide bar, and gear one, thereby adjusting the angle of one end of the thin blade. At the same time, the connection between the movable block and the rotating block allows the other end of the blade to move flexibly, easily completing the overall angle adjustment. The operation is simple and precise. If the thin blade is bent, simply push the insert block one to compress the spring, increasing the distance between the mechanisms, and pull out the insert block two and insert block one to quickly remove and replace a single set of thin blades. This solves the problem of cumbersome or even impossible replacement of single sets of blades in traditional Venetian blinds, greatly facilitating daily use. The entire device is fixed to the wall with the help of upper and lower mounting rails and mounting holes. When not in use, it can be stored horizontally by connecting the rails and the side frame, avoiding the problem of frequent pulling and jamming of roller blinds. Installation and disassembly are more convenient, and daily cleaning is also much easier. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 6 In this embodiment of the utility model, the Venetian blind with a shading control device includes: a side frame 1, which serves as an overall support structure; a stepper motor 2 is fixedly connected to one end of the outer side of the side frame 1, which serves as a driving source for angle adjustment; a gear 3 is fixedly connected to the output end of the stepper motor 2, which drives the gear 3 to rotate; a limit plate 4 is fixedly connected to one end of the back of the side frame 1 to ensure movement stability; a quick-connect mechanism 5 is provided on one side inside the side frame 1; a driven mechanism 6 is provided on the other side inside the side frame 1; a thin blade 7 is provided between the quick-connect mechanism 5 and the driven mechanism 6; and a core light-shading component.

[0023] The limiting plate 4 has a sliding strip 8 slidably connected to the front, a toothed block 9 fixedly connected to the front of the sliding strip 8, and a toothed block 10 fixedly connected to the back of the sliding strip 8. The gear 3 meshes with the toothed block 10. The sliding strip 8 connects the toothed block 9 and the toothed block 10, converting the rotational motion of the stepper motor 2 into horizontal sliding. There are multiple sets of toothed blocks 9, which are symmetrically arranged on the front of the sliding strip 8. There are several sets of toothed blocks 10 on the back of the sliding strip 8. There are multiple sets of quick-connect mechanism 5, driven mechanism 6 and thin blade 7. Multiple sets of quick-connect mechanism 5 are vertically symmetrically arranged on one side inside the side frame 1, and multiple sets of driven mechanism 6 are vertically symmetrically arranged on the other side inside the side frame 1.

[0024] Reference Figure 1 The top of the side frame 1 is movably connected to the upper mounting rail 11, and the bottom of the side frame 1 is movably connected to the lower mounting rail 12. One end of the upper mounting rail 11 is provided with a mounting hole 13, and one end of the lower mounting rail 12 is also provided with a mounting hole 13. The upper mounting rail 11 and the lower mounting rail 12 work together to enable the device to move horizontally and be stored, avoiding obstruction.

[0025] Reference Figure 1 , Figure 2 and Figure 5 The quick-connect mechanism 5 includes a fixed post 501, a spring 502, and a movable block 503. The fixed post 501 is fixedly connected to one side of the side frame 1. The spring 502 is fixedly connected to the inside of the fixed post 501. The movable block 503 is movably inserted into the fixed post 501. The fixed post 501 houses the spring 502 and the movable block 503, limiting the direction of movement. The spring 502 provides elastic restoring force. After compression, it increases the distance between the quick-connect mechanism 5 and the driven mechanism 6, making it easier to disassemble the thin blade 7. The movable block 503 serves as a retractable connecting component.

[0026] Rotating block 504 and insert block 505 are rotatably connected to one end of movable block 503 to realize the rotating interface for adjusting the angle of thin blade 7. Insert block 505 is inserted into rotating block 504 and is a quick-connect piece at one end of thin blade 7. The other end of insert block 505 is snapped into thin blade 7.

[0027] Reference Figure 1 , Figure 2 and Figure 6 The driven mechanism 6 includes a rotating column 601, a second gear 602, and a second insert block 603. The rotating column 601 is rotatably connected to the other side of the side frame 1 and is the shaft that transmits rotational motion. The second gear 602 is fixedly connected to one end of the outer side of the rotating column 601 and meshes with the first gear block 9 to achieve angle adjustment. The second insert block 603 is inserted into the rotating column 601, and the other end of the second insert block 603 is engaged with the thin blade 7. The other end of the thin blade 7 has a quick-connect component, and the second gear 602 meshes with the first gear block 9.

[0028] The working principle of this utility model is as follows: When the stepper motor 2 starts, its output end drives the gear 3 to rotate. Since the gear 3 meshes with the tooth block 10, it will drive the slide bar 8 to slide along the front of the limiting plate 4. The multiple sets of tooth blocks 9 on the front of the slide bar 8 will mesh with the gear 602 in the driven mechanism 6, thereby driving the rotating column 601 to rotate. This causes the insert block 603 to rotate with the rotating column 601, realizing the rotation adjustment of one end of the thin blade 7. At the same time, through the rotational connection between the movable block 503 and the rotating block 504, the other end of the thin blade 7 can also be adjusted relatively flexibly with the rotation of one end of the driven mechanism 6, realizing the overall angle adjustment of the thin blade 7. When a set of thin blades 7 bends during daily use, simply push the insert block 505 towards the fixed column 501, so that the movable block 503 is retracted in the fixed column 501 and the spring 502 is compressed, thereby making the quick-connect mechanism 5 The distance between the driven mechanism 6 and the auxiliary mechanism 6 is increased. Then, the second insert 603 is pulled out from the rotating column 601, and the first insert 505 is pulled out from the rotating block 504. In this way, the single set of thin blades 7 can be quickly removed. Then, the two ends of the new single set of thin blades 7 are respectively clipped with the first insert 505 and the second insert 603 for installation. This avoids bending or twisting of the single set of thin blades 7, which is cumbersome or even impossible to replace, thus affecting daily use. This design also facilitates quick removal of the whole unit for easy daily cleaning. With the setting of the upper mounting rail 11, the lower mounting rail 12 and the mounting hole 13, the entire device can be placed on the wall. When not in use, it can be moved horizontally through the connection between the upper mounting rail 11, the lower mounting rail 12 and the side frame 1. This avoids jamming caused by frequent pulling of the roller shutter, and the installation and disassembly are also more convenient.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
