Description

Technical Field

[0001] This utility model relates to the field of blinds, and in particular to a manual composite blind. Background Technology

[0002] Venetian blinds are an upgraded product of traditional fixed single-layer rainproof louvers. With market demand, in addition to retaining the original ventilation performance of louvers, the louver blades also have an adjustable rotation function, allowing users to adjust the blade angle arbitrarily according to actual needs.

[0003] The manual switches of existing manual blinds are mostly exposed outside the frame. Not only are they easily affected by external forces and accidentally touched, causing the angle of the blind slats to change, but the exposed switches are also prone to accumulating dust and dirt when exposed to the air for a long time, making them difficult to clean. If cleaning is not done in time, the switches will look old and dirty, further affecting the cleanliness of the home environment. Utility Model Content

[0033] 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.

[0034] Example 1

[0035] This utility model provides, for example Figure 1-3 The manual composite venetian blind shown includes a fixed frame 1, a connecting frame 2, a rotating shaft 3, blades 4, an adjustment mechanism 5, and a synchronization mechanism 6. The connecting frame 2 is fixedly connected to the fixed frames 1. The ends of the rotating shafts 3 are equidistantly inserted and rotatably connected to the fixed frames 1. The blades 4 are fixedly inserted and rotatably connected to the rotating shafts 3. The adjustment mechanism 5 is located inside one of the fixed frames 1 and is used to drive the rotation of one of the rotating shafts 3. The synchronization mechanism 6 is located inside the other fixed frame 1 and is used to synchronize the rotation of the blades 4. By utilizing the coordinated arrangement of the adjustment mechanism 5 and the synchronization mechanism 6, and by concealing both the adjustment mechanism 5 and the synchronization mechanism 6 inside the fixed frames 1, the venetian blinds have a simpler and smoother appearance, without any abrupt opening or closing or complex structure exposed. This avoids the problem of accidental activation caused by traditional exposed switches and is less affected by external environmental factors. Unlike traditional exposed switches, they are not directly exposed to dust, moisture, and direct sunlight, reducing the possibility of rust, corrosion, and aging, thereby extending the service life of the entire venetian blind adjustment system and reducing maintenance and replacement costs.

[0036] Specifically, the adjustment mechanism 5 includes a worm gear 51, a worm 52, and a rotation positioning component 53. The worm gear 51 is fixedly inserted and connected to one end of one of the rotating shafts 3. The end of the worm 52 is rotatably inserted and connected to the inner wall of one of the fixed frames 1. The worm 52 is meshed with the worm gear 51. The worm gear 52 can drive the worm gear 51 to rotate, so the rotating shaft 3 connected to the worm gear 51 can drive the other rotating shafts 3 to rotate through the synchronization mechanism 6, thereby realizing the adjustment of all blades 4. The rotation positioning component 53 is connected to the worm 52 and is used to drive the worm 52 to rotate and position.

[0037] Furthermore, the rotation positioning assembly 53 includes a turntable 531, a telescopic rod 532, a positioning block 533, and a compression spring 534. The outer wall of the fixing frame 1 has a rotation groove for housing the turntable 531. One end of the worm gear 52 has a telescopic groove, and one end of the telescopic rod 532 is slidably inserted into the inner cavity of the telescopic groove. The cross-section of the telescopic rod 532 is T-shaped. The positioning block 533 is symmetrically fixedly connected to the turntable 531. Positioning holes are equidistantly opened on the inner wall of the rotation groove, and multiple positioning holes are arranged in a ring inside the rotation groove. The positioning block 533 is slidably inserted into the inner cavity of the positioning hole, thus achieving the positioning of the turntable 531. The compression spring 534 is sleeved on the outside of the telescopic rod 532, with one end of the compression spring 534 fixedly connected to the telescopic rod 532 and the other end fixedly connected to the inner wall of the telescopic groove. The compression spring 534 always provides a stable elastic force to the turntable 531 through the telescopic rod 532, so that the positioning block 533 can be stably engaged with the positioning hole. While hiding the turntable 531 inside the fixing frame 1, it can also position the worm gear 52, preventing it from loosening due to slight external vibrations or collisions. This ensures the stable positioning of the worm gear 52, thereby guaranteeing the stability of the synchronous mechanism 6 driving the blades 4 to rotate. This allows the louver blades 4 to remain fixed after being adjusted to a specific angle, preventing the angle from changing on its own. This reduces the safety hazards that may be caused by the sudden rotation of the blades 4, such as pinching fingers. At the same time, hiding the turntable 531 inside the fixing frame 1 also reduces the possibility of misoperation caused by external objects colliding with the turntable 531, providing a safer operating environment for users.

[0038] Example 2

[0039] Based on Example 1, such as Figure 4As shown, the synchronization mechanism 6 includes a gear 61, a rack 62, and a slider 63. The gear 61 is fixedly inserted into the end of the rotating shaft 3, and the rack 62 is meshed with the gear 61. The inner wall of another fixed frame 1 is provided with a sliding groove, and the slider 63 is slidably inserted into the inner cavity of the sliding groove. The slider 63 is fixedly connected to the rack 62. The cross-sections of both the slider 63 and the sliding groove are T-shaped. The slider 63 plays a supporting and limiting role for the rack 62, so that the rack 62 can only move in the vertical direction. When the worm gear 51 drives one of the rotating shafts 3 to rotate, the rack 62 can be driven to slide through the gear 61 on this rotating shaft 3, thereby driving the other gears 61 to rotate, realizing the synchronous adjustment of the blade 4 direction.

[0040] 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.
