Description
Technical Field
[0001] This utility model belongs to the field of architectural decoration technology, specifically a louver with adjustable angle. Background Technology
[0002] Venetian blinds are widely used in homes, schools, and workplaces, offering advantages such as flexible light adjustment, good privacy protection, and excellent ventilation.
[0003] Adjustable blinds are a type of window covering that allows for adjustment of the angle and position of the slats through mechanical or electronic devices, enabling flexible control of light, privacy, and ventilation.
[0004] Traditional venetian blinds are limited by structural design and mechanical principles, and can usually only open in one direction (such as tilting to the left or right), making it difficult to adjust the opening and closing angles to both sides at the same time. Therefore, a venetian blind with adjustable angle is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a louver with an adjustable angle.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An adjustable-angle venetian blind, comprising a curtain box, a first fixed thin-walled plate fixed to the inner wall of the curtain box, a support column fixed to the inner wall of the first fixed thin-walled plate, a third fixed thin-walled plate fixed to the end of the support column, a first fixed pulley support column fixed to the top of the support column, a first fixed pulley fixed to the top of the first fixed pulley support column, a second fixed thin-walled plate fixed to the inner wall of the curtain box, a second fixed pulley fixed to the inner wall of the second fixed thin-walled plate, a second support column fixed to the top of the second fixed pulley, a traction rope provided on the outer wall of the first fixed pulley, a first traction block provided in the middle section of the traction rope, and preferably, second traction blocks symmetrically provided on the first traction block, a hanging ring provided on the outer wall of the support column, a connecting member fixed to the bottom of the hanging ring, a connecting rod extension end provided at the bottom of the connecting member, and a connecting rod fixing end provided in the middle of the connecting rod extension end.
[0007] Preferably, the extension end of the connecting rod is provided with a gravity movable rod inside, the gravity movable rod is provided with a gravity movable rod groove inside, and a connecting rod is fixedly connected to the inner wall of the gravity movable rod groove.
[0008] Preferably, the end of the connecting rod is provided with a clamping plate, the outer wall of the clamping plate is provided with a clamping plate hole, and a curtain is fixedly connected inside the clamping plate.
[0009] Preferably, the inner wall of the curtain box is provided with a fixing post, the outer wall of the fixing post is provided with a fixing post groove, and a pull rope is provided inside the fixing post groove.
[0010] Preferably, a pull rope is provided inside the clamping plate hole.
[0011] The beneficial effects of this utility model are: 1. This utility model provides an adjustable louver. By setting a first traction block in the middle of the traction rope and a second traction block symmetrically arranged on the traction block, a "midpoint traction + double-sided symmetrical force" structure is formed. When the traction rope is pulled, the traction blocks on both sides can simultaneously drive the louver blades to slide, avoiding blade tilting or jamming caused by unilateral force, realizing the smoothness and consistency of angle adjustment, freeing up the middle view and avoiding obstruction.
[0012] 2. This utility model provides an adjustable-angle venetian blind. A gravity-operated movable rod is installed inside the extended end of the connecting rod. When the traction rope moves, the gravity-operated movable rod falls due to its own weight, pulling the connecting rod assembly via the connecting rod, causing the slats to automatically return to a vertical position, achieving a vertical downward function. A clamp is provided at the end of the connecting rod, allowing relative rotation during adjustment. The blind rotates with the clamp. A fixed post groove is provided on the outer wall of the fixed post, providing a rigid guide track for the pull rope, ensuring the pull rope maintains a straight line during adjustment and preventing rope entanglement due to slack or external interference. A pull rope is installed inside the fixed post groove; by pulling both ends of the pull rope, the clamp can be adjusted to drive the blind to swing at different angles. Attached Figure Description

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Specific implementation examples are given below.
[0017] Please see Figure 1 and Figure 2 This utility model provides an adjustable-angle venetian blind, including a curtain box 1; a first fixed thin-walled plate 101 is fixedly connected to the inner wall of the curtain box 1, a support column 102 is fixedly connected to the inner wall of the first fixed thin-walled plate 101, a third fixed thin-walled plate 103 is fixedly connected to the end of the support column 102, a first fixed pulley support column 104 is fixedly connected to the top of the support column 102, a first fixed pulley 105 is fixedly connected to the top of the first fixed pulley support column 104, a second fixed thin-walled plate 106 is fixedly connected to the inner wall of the curtain box 1, and a second fixed pulley 107 is fixedly connected to the inner wall of the second fixed thin-walled plate 106. The second fixed pulley 107 is fixedly connected to the top of the second support column 108. The outer wall of the first fixed pulley 105 is provided with a traction rope 111. The middle section of the traction rope 111 is provided with a first traction block 109. The first traction block 109 is symmetrically provided with a second traction block 110. In operation, in the prior art, the curtain can only be adjusted by force on one side and in one direction, and cannot be adjusted at the same time. Therefore, by setting traction blocks, a "midpoint traction + double-sided symmetrical force" structure is formed. When the traction rope is pulled, the traction blocks on both sides drive the curtain to slide synchronously, so as to achieve consistent adjustment of the opening and closing angle, release the middle view, and avoid obstruction.
[0018] Furthermore, such as Figure 2 and Figure 3As shown, the outer wall of the support column 102 is provided with a hanging ring 2. A connector 201 is fixedly connected to the bottom of the hanging ring 2. The bottom of the connector 201 is provided with a connecting rod extension end 202. The middle part of the connecting rod extension end 202 is provided with a connecting rod fixing end 203. During operation, by setting the hanging ring 2 on the outer wall of the support column 102, the hanging ring 2 and the connecting rod assembly can form a mechanical linkage with the traction rope 111 and the fixed pulleys (such as the first fixed pulley 105 and the second fixed pulley 107). By setting the support column 102, the support column 102 distributes the weight of the connecting rod assembly and adjusts the tension through multiple hanging rings 2 (if distributed along the height direction), avoiding a single hanging ring bearing the entire load. By setting the hanging ring 2 on the wall of the support column 102, the hanging ring 2 and the connecting rod assembly can form a mechanical linkage with the traction rope 111 and the fixed pulleys (the first fixed pulley 105 and the second fixed pulley 107).
[0019] Furthermore, such as Figure 3 and Figure 5 As shown, the extension end 202 of the connecting rod is provided with a gravity movable rod 3 inside, and the gravity movable rod 3 is provided with a gravity movable rod groove 301 inside. A connecting rod 302 is fixedly connected to the inner wall of the gravity movable rod groove 301. During operation, by setting the gravity movable rod 3 inside the extension end 202, when the traction rope moves, the gravity movable rod 3 falls due to its own weight, and pulls the connecting rod assembly through the connecting rod 302, so that the blade automatically returns to the vertical state, realizing the vertical downward function.
[0020] Furthermore, such as Figure 2 and Figure 5 As shown, the end of the connecting rod 302 is provided with a clamping plate 4, the outer wall of the clamping plate 4 is provided with a clamping plate hole 401, and the curtain 402 is fixedly connected inside the clamping plate 4. During operation, by setting the end of the connecting rod 302 to be provided with a clamping plate 4, relative rotation is achieved during adjustment, and the curtain rotates with the clamping plate.
[0021] Furthermore, such as Figure 3 and Figure 4 As shown, the inner wall of the curtain box 1 is provided with a fixing post 5, the outer wall of the fixing post 5 is provided with a fixing post groove 501, the inside of the fixing post groove 501 is provided with a pull rope 502, and the inside of the clamp hole 401 is provided with a pull rope 502. During operation, by setting the fixing post groove 501 on the outer wall of the fixing post 5, the fixing post groove 501 provides a rigid guide track for the pull rope 502, ensuring that the pull rope maintains a straight movement during adjustment and avoiding rope entanglement caused by slackness or external interference. By setting the pull rope 502 inside the fixing post groove 501, by pulling the two ends of the pull rope, the clamp can be adjusted to drive the curtain to swing at different angles.
[0022] Working Principle: In existing technology, curtains can only be adjusted in one direction and under one-sided force, not simultaneously. Therefore, by setting traction blocks, a "midpoint traction + symmetrical force on both sides" structure is formed. Pulling the traction rope causes the traction blocks on both sides to slide the curtain synchronously, achieving consistent adjustment of the opening and closing angle, releasing the central view and avoiding obstruction. The support column 102 has hanging rings 2 on its outer wall. The hanging rings 2 and the connecting rod assembly can form a mechanical linkage with the traction rope 111 and fixed pulleys (such as the first fixed pulley 105 and the second fixed pulley 107). The support column 102, through multiple hanging rings 2 (distributed along the height direction), distributes the weight and adjustment force of the connecting rod assembly, preventing a single hanging ring from bearing the entire load. The support column 102 also has hanging rings 2 on its outer wall. The connecting rod assembly can form a mechanical linkage with the traction rope 111 and the fixed pulleys (first fixed pulley 105 and second fixed pulley 107). By setting a gravity movable rod 3 inside the extension end 202 of the connecting rod, when the traction rope moves, the gravity movable rod 3 falls due to its own weight, and pulls the connecting rod assembly through the connecting rod 302, so that the blades automatically return to the vertical state, realizing the vertical downward function. By setting a clamp 4 at the end of the connecting rod 302, relative rotation is generated during adjustment, and the curtain rotates with the clamp. By setting a fixed post groove 501 on the outer wall of the fixed post 5, the fixed post groove 501 provides a rigid guide track for the pull rope 502, ensuring that the pull rope maintains a straight movement during adjustment and avoiding rope entanglement caused by slack or external interference. By setting a pull rope 502 inside the fixed post groove 501, by pulling the two ends of the pull rope, the clamp can be adjusted to drive the curtain to swing at different angles.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
