[0004] The above structure is the same as the existing structure. The traction mechanism controls the lifting and lowering of the Venetian blinds. However, the ratio is 1:1 or 1:2. This requires the traction mechanism to be moved a longer distance to fully open or tighten the Venetian blinds. Moreover, the traction rope lacks a locking device. The Venetian blinds have a certain weight, and under the action of gravity, the traction rope will loosen, causing the Venetian blinds to open fully and making it impossible to stop the Venetian blinds in any position.

[0007] As another rope winding method of this utility model, one end of the lifting rope is fixed to the top of the lifting seat, and the other end passes through the winding ratchet, the movable pulley and the fixed pulley in sequence, then passes down through each blade and then through one end of the lower beam of the blade, and then from the other end of the lower beam of the blade upward, passes through each blade, passes through the fixed pulley, the movable pulley and the winding ratchet, and is then fixed to the top of the lifting seat. The two lifting ropes are provided with three sections of force rope between the fixed pulley, the movable pulley and the winding ratchet.

[0008] As a further improvement of this utility model, the lifting seat is provided with a fixed column, the winding ratchet is located between the fixed pulley and the movable pulley, and the lifting ropes are wound sequentially around the fixed pulley, the movable pulley, and the winding ratchet. The ends of the lifting ropes are fixed to the fixed column, and the lifting control handle and the lifting seat are attracted to each other by a magnet.

[0009] As a further improvement of this utility model, the above-mentioned winding ratchet includes a take-up reel and a gear, and the above-mentioned double-linked upper housing is also provided with a pawl, and the pawl and the gear cooperate with each other.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0032] like Figures 1 to 12 As shown: This utility model designs a built-in sunshade venetian blind to reduce the travel of the lifting control handle, while adding a limiting device so that the venetian blind can be stopped at any position.

[0033] Example 1, as follows: Figures 1 to 2 As shown, this utility model mainly includes an insulated glass unit 1, a mounting frame 2, a Venetian blind 3, a lifting and adjusting device 4, and a blade flipping device 5. The mounting frame 2 provides support, and the insulated glass unit 1 is installed on the mounting frame 2; the Venetian blind 3 is set between the insulated glass units 1 by ropes; the Venetian blind 3 includes a lower beam 31 and several blades 32; the lifting and adjusting device 4 and the blade flipping device 5 are set on the outer surface of the insulated glass unit 1. This utility model mainly controls the lifting and lowering movement of the Venetian blind 3 and the rotation angle of the blades 32. The lifting and adjusting device 4 is used to control the arrangement height of the Venetian blind 3, and the blade flipping device 5 is used to adjust the shading angle of the Venetian blind 3.

[0034] like Figures 3 to 4 As shown, the lifting adjustment device 4 of this utility model is used to control the arrangement height of the Venetian blind 3. The lifting adjustment device 4 includes a lifting control handle 41, a lifting seat 42, a double upper box 43 and two lifting pull ropes 44. The lifting control handle 41 is slidably disposed on the outer surface of the inner glass 12, and the lifting control handle 41 and the lifting seat 42 are attracted to each other by magnets.

[0035] One end of each lifting rope 44 passes through each blade 32 in sequence and is fixed to the lower beam 31 of the blade; the double-linked upper box 43 is provided with a fixed pulley 431 and a winding ratchet 432, and the lifting seat 42 is provided with a movable pulley 421. Each lifting rope 44 is wound around the fixed pulley 431, the movable pulley 421 and the winding ratchet 432, and one end of its end is fixed to the lifting seat 42; the blade flipping device 5 is used to adjust the shading angle of the Venetian blind 3; the lifting control handle 41 moves up and down, driving the lifting seat 42 to move up and down synchronously, so that at least one lifting rope 44 pulls the lower beam 31 of the blade, so that the Venetian blind 3 unfolds to different distances.

[0036] To reduce the travel distance of the lifting control handle 41, in the lifting adjustment device 4, the other end of each lifting rope 44 is wound around the fixed pulley 431, the movable pulley 421 and the winding ratchet 432. Each lifting rope 44 is wound into three sections of tension rope between the fixed pulley 431, the movable pulley 421 and the winding ratchet 432, and fixed to the top of the lifting seat 42. That is, one end is first fixed to the fixed column 422 of the lifting seat 42, then goes up around the winding ratchet 432, then down around the movable pulley 421, then up around the fixed pulley 431, then through each blade 32, and finally the other end is fixed to the lower beam 31 of the blade. Through the above winding method, the lifting pull rope 44 is wound into three segments in the lifting adjustment device 4. Therefore, the moving distance of the lifting seat 42 is three times the moving distance of the lifting pull rope 44. That is, the moving distance of the Venetian blind 3 is three times that of the lifting control handle 41. In this way, the user can control the Venetian blind 3 to rise or fall completely by moving the lifting control handle 41 a shorter distance. This avoids the technical problem of traditional Venetian blinds requiring the lifting control handle to move the same distance when rising or falling. This is especially effective for floor-length Venetian blinds or Venetian blinds with a high height, or when a safety guard frame is installed.

[0037] As another rope winding method, one end of the lifting rope 44 is fixed to the top of the lifting seat 42, and the other end passes through the winding ratchet 432, the movable pulley 421 and the fixed pulley 431 in sequence, then passes down through each blade 32 and through one end of the blade lower beam 31, then from the other end of the blade lower beam 31 upward, passes through each blade 32, passes through the fixed pulley 431, the movable pulley 421 and the winding ratchet 432, and is then fixed to the top of the lifting seat 42. The two lifting ropes 44 are arranged in three sections between the fixed pulley 431, the movable pulley 421 and the winding ratchet 432. With this rope winding method, only one lifting rope 44 is needed to control the lifting and lowering of the blade 32. When the blade 32 descends, the height of the left and right ends is automatically adjusted, and the blade lower beam 31 is automatically adjusted for balance.

[0038] like Figures 4 to 6 As shown, the double-linked upper housing 43 is provided with a fixed pulley 431 and a winding ratchet 432, and the lifting seat 42 is provided with a movable pulley 421 and a fixed column 422. The winding ratchet 432 is located between the fixed pulley 431 and the movable pulley 421. In this utility model, the fixed pulley 431 and the winding ratchet 432 are fixed rotating wheels, and the movable pulley 421 and the fixed column 422 move synchronously with the lifting seat 42.

[0039] To limit the position of the lifting rope 44 and prevent it from winding around the ratchet 432 and reversing, such as Figures 5 to 6As shown, the winding ratchet 432 of this utility model includes a take-up reel 4321 and a gear 4322. A pawl 433 is also provided on the double-linked upper housing 43. The pawl 433 and the gear 4322 cooperate so that the gear 4322 can only rotate in one direction and cannot rotate in reverse.

[0040] like Figure 6 As shown, the take-up reel 4321 includes multiple rectangular surfaces 4320 connected in sequence, and an arc-shaped connecting surface 4323 is provided between each pair of adjacent rectangular surfaces 4320. The rectangular surfaces 4320 can ensure the winding force, while the circular surfaces are prone to slippage. At the same time, by providing the arc-shaped connecting surface 4323, the shearing force on the lifting rope 44 can be reduced, thus reducing the wear on the lifting rope 44.

[0041] To reduce the control force of the lifting control handle 41, a counterweight 7 is connected to the bottom of the lifting base 42. Since the moving distance of the lifting rope 44 is reduced to one-third of the original distance, its pulling force is three times that of the original distance, which is three times the weight of the blind. At this time, the lifting control handle 41 needs to be pulled down with greater force. In order to make it easier to pull down, a counterweight 7 is set below the blind 3. By using the gravity of the counterweight 7, the pulling force of the lifting control handle 41 can be reduced, making the operation of the lifting control handle 41 easier.

[0042] In order to adjust the rotation angle of the blade 32, the blade flipping device 5 includes a flipping shaft 51, a flipping ladder belt 52, a flipping seat 53, and a flipping operation knob 54. The flipping ladder belt 52 is wound around the flipping shaft 51, with 1-5 turns. The flipping ladder belt 52 positions and connects all the parallel blades 32.

[0043] The flip operation slider 54 is slidably mounted on the inner glass layer 12, and the flip operation slider 54 and the flip base 53 are attracted by a magnet.

[0044] Example 2 includes all the technical features of Example 1. This device can be installed in the insulating glass 1, such as... Figure 8 As shown, the insulated glass 1 can be provided with two layers, including an inner glass layer 12 and an outer glass layer 11; the inner glass layer 12 and the outer glass layer 11 are respectively fixed on the mounting frame 2.

[0045] Example 3, as Figures 9-12 As shown, including all the technical features of Embodiment 1, the hollow glass 1 includes an inner glass layer 12 and an outer glass layer 11, and an intermediate glass layer 13 is also provided. The Venetian blind 3, the lifting and adjusting device 4 and the blade flipping device 5 in Embodiment 1 are arranged between the outer glass layer 11 and the intermediate glass layer 13. The intermediate glass layer 13 is located between the inner glass layer 12 and the outer glass layer 11. An additional layer of glass is added between the inner glass layer 12 and the outer glass layer 11, which further plays a role in heat preservation.

[0046] like Figure 7 As shown, two intermediate magnetic sliding plates 6 are also provided between the intermediate glass layer 13 and the inner glass layer 12. One intermediate magnetic sliding plate 6 is located between the lifting control handle 41 and the lifting seat 42, and the lifting control handle 41 controls the movement of the lifting seat 42 through the intermediate magnetic sliding plate 6. The other intermediate magnetic sliding plate 6 is located between the flip operation button 54 and the flip seat 53, and the flip operation button 54 controls the movement of the flip seat 53 through the intermediate magnetic sliding plate 6. The intermediate magnetic sliding plate 6, the lifting control handle 41, and the flip operation button 54 are all provided with multiple bottom pulleys 61 and magnet blocks 62. The magnet blocks 62 attract each other, and the bottom pulleys 61 can reduce the friction of movement, making it easier to move the intermediate magnetic sliding plate 6, the lifting control handle 41, and the flip operation button 54.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. For those skilled in the art, several modifications and improvements can be made without departing from the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
