This invention effectively improves the stability of Venetian blinds by limiting and storing them, and facilitates synchronous transport by the guide rail. However, the above solution has the following drawbacks: the existing Venetian blind guide rail uses a drive wheel to drive a transmission belt to transport the blinds outside the guide wheel. A rack is provided on the outside of the transmission belt, which facilitates the manipulation and limiting of the Venetian blinds, ensuring the stability of the blind storage housing. However, the above components are cumbersome to operate, inconvenient to install and disassemble, and difficult to disassemble and replace when malfunctions occur, making them inconvenient to use.

[0004] Therefore, this application provides a guide rail structure for Venetian blinds to solve the above problems. Utility Model Content

[0005] This application provides a guide rail structure for Venetian blinds, aiming to solve the problems mentioned in the background art. Existing Venetian blind guide rails use a drive wheel to drive a transmission belt to transmit data on the outside of the guide wheel. A rack is provided on the outside of the transmission belt, which facilitates the movement and limiting of the Venetian blinds, ensuring the stability of the blind storage housing. However, the above components are cumbersome to operate, inconvenient to install and disassemble, and difficult to disassemble and replace when malfunctions occur, resulting in inconvenience in use.

[0006] To achieve the above objectives, this application provides the following technical solution: a guide rail structure for Venetian blinds, wherein the guide rail structure for Venetian blinds includes a guide rail mechanism;

[0007] Preferably, to address the problem that existing Venetian blind guide rails use a drive wheel to drive a transmission belt that moves the blinds outside the guide wheel, and a rack is provided on the outside of the transmission belt, allowing for easy movement and positioning of the Venetian blinds, thus ensuring the stability of the blind storage housing, the guide rail mechanism includes a connecting rod. A Venetian blind body is mounted on the outside of the connecting rod. Rotating blocks are fixedly connected to both ends of the connecting rod. Each set of rotating blocks has multiple sets of slots inside, and a pull cord is mounted outside each slot. A rotating shaft is located inside each rotating block, and a mounting block is located outside each rotating block. The mounting block has a mounting groove inside, and the rotating shaft is positioned inside the mounting groove. The pull cord is looped around the slot inside the rotating block, and pressing the rotating shaft causes it to slide outside the limiting rod. A spring on the side of the shaft compresses the shaft, causing it to enter the interior of the rotating block. Two sets of rotating blocks are placed between two sets of mounting blocks. The shaft, subjected to the rebound force of spring one, engages with the mounting groove inside the mounting block. A protective shell is then installed between the mounting blocks, which are secured with bolts. Pulling the pull cord engages with the slot, causing the rotating block to rotate within the mounting groove. This allows the Venetian blind body mounted on the outside of the connecting rod to be raised and lowered. A fixed roller on one side of the shaft engages with a locking block. When the shaft rotates the fixed roller, the external protrusion of the fixed roller pushes the locking block. The locking block, under pressure, pushes the moving rod to slide inside the connecting block, causing the moving rod to compress spring two. The fixed roller stops rotating, and the locking block, subjected to the rebound force of spring two, engages with the fixed roller, preventing the shaft from rotating due to the weight of the Venetian blind body. This allows for easy installation and disassembly, is simple and quick to operate, and is convenient to use.

[0008] Preferably, in order to solve the problem of the stability of the rotating shaft movement, a limiting rod is fixedly connected inside the rotating block, the rotating shaft is set outside the limiting rod, and the rotating shaft is slidably connected to the limiting rod. The limiting rod can improve the stability of the rotating shaft movement.

[0009] Preferably, in order to solve the problem of convenient use of the rotating shaft, a spring is provided inside the rotating block. The spring is fixedly connected between one side of the rotating shaft and the inside of the rotating block. During the movement of the rotating shaft, the spring provided on the side will be compressed. Through the spring, the rotating shaft can be easily restored to its original shape, making it convenient to use.

[0010] Preferably, to solve the problem of easy fixing of the rotating shaft, a fixed roller is fixedly connected to one side of the rotating shaft, and a connecting block is fixedly connected to one side of the mounting block. A moving rod is provided inside the connecting block, and a locking block is fixedly connected to one end of the moving rod. The locking block locks with the fixed roller. When the rotating shaft drives the fixed roller to rotate, the external protrusion of the fixed roller will push the locking block. The locking block, under force, will push the moving rod to slide inside the connecting block, so that the moving rod compresses the second spring, the fixed roller stops rotating, and the locking block will be locked with the fixed roller by the rebound force of the second spring. This prevents the rotating shaft from rotating due to the weight of the Venetian blind body, making it convenient to use.

[0011] Preferably, in order to solve the problem of convenient use of the movable rod, the movable rod is slidably connected to the connecting block, and the connecting block is provided with a second spring. The second spring is fixedly connected between one side of the movable rod and the inside of the connecting block. With the second spring, the movable rod can be easily restored to its original state, making it convenient to use.

[0012] Preferably, to address the protection issue, a protective shell is bolted between the two sets of mounting blocks. The protective shell is located outside the connecting rod, thus protecting the connecting rod and the main body of the Venetian blind.

[0013] This guide rail mechanism involves placing a pull cord around the slot inside the rotating block. Pressing the rotating shaft causes it to slide outside the limiting rod, compressing a spring on its side and forcing it into the rotating block. Two sets of rotating blocks are placed between two sets of mounting blocks. The rotating shaft, subjected to the rebound force of spring one, engages with the mounting slot inside the mounting block. A protective shell is then installed between the mounting blocks, which are secured with bolts. Pulling the pull cord engages with the slot, causing the rotating block to rotate the shaft within the mounting slot. This allows the Venetian blind body outside the connecting rod to be raised and lowered. A fixed roller on one side of the rotating shaft engages with a locking block. When the rotating shaft drives the fixed roller to rotate, a protrusion on the fixed roller pushes the locking block, which in turn pushes the moving rod to slide inside the connecting block. This causes the moving rod to compress spring two, stopping the fixed roller's rotation. The locking block, subjected to the rebound force of spring two, engages with the fixed roller, preventing the rotating shaft from rotating due to the weight of the Venetian blind body. This design allows for easy installation and disassembly, is simple and quick to operate, and is convenient to use. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a guide rail structure for Venetian blinds, such as... Figure 1-6 As shown, the Venetian blind uses a guide rail structure, which includes a guide rail mechanism 1.

[0025] The guide rail mechanism 1 allows for easy installation and disassembly, making the operation simple, quick, and convenient.

[0026] Specifically, the guide rail mechanism 1 includes a connecting rod 11, a Venetian blind body 12 is provided on the outside of the connecting rod 11, and rotating blocks 13 are fixedly connected to both ends of the connecting rod 11. Multiple sets of holes and slots 14 are opened inside a set of rotating blocks 13. Pull cords 15 are provided on the outside of the holes and slots 14. A rotating shaft 16 is provided inside the rotating blocks 13. An installation block 17 is provided on the outside of the rotating blocks 13. An installation groove 18 is opened inside the installation block 17. The rotating shaft 16 is located inside the installation groove 18.

[0027] In use, the pull rope 15 is fitted over the slot 14 inside the rotating block 13. Pressing the rotating shaft 16 causes it to slide outside the limiting rod 19, compressing the spring 20 on its side and allowing it to enter the rotating block 13. The two sets of rotating blocks 13 are placed between the two sets of mounting blocks 17. The rotating shaft 16, subjected to the rebound force of the spring 20, engages with the mounting groove 18 inside the mounting block 17. The protective shell 26 is then installed between the mounting blocks 17, which are secured with bolts. Pulling the pull rope 15 causes it to engage with the slot 14, thus causing the rotating block 13 to be forced to rotate the shaft 16 within the mounting block. The internal rotation of the groove 18 allows the Venetian blind body 12, which is externally mounted on the connecting rod 11, to be extended or retracted. The fixed roller 21 on one side of the rotating shaft 16 engages with the locking block 24. When the rotating shaft 16 drives the fixed roller 21 to rotate, the external protrusion of the fixed roller 21 pushes the locking block 24. The locking block 24, under force, pushes the moving rod 23 to slide inside the connecting block 22, causing the moving rod 23 to compress the second spring 25. The fixed roller 21 stops rotating, and the locking block 24 engages with the fixed roller 21 under the rebound force of the second spring 25. This prevents the rotating shaft 16 from rotating due to the gravity of the Venetian blind body 12, making installation and disassembly convenient. The operation is simple, quick, and easy to use.

[0028] Furthermore, a limiting rod 19 is fixedly connected inside the rotating block 13, and the rotating shaft 16 is located outside the limiting rod 19. The rotating shaft 16 is slidably connected to the limiting rod 19. The limiting rod 19 can improve the stability of the movement of the rotating shaft 16.

[0029] Furthermore, a spring 20 is provided inside the rotating block 13. The spring 20 is fixedly connected between one side of the rotating shaft 16 and the inside of the rotating block 13. During the movement of the rotating shaft 16, the spring 20 on the side will be compressed. Through the spring 20, the rotating shaft 16 can be easily restored to its original state, making it convenient to use.

[0030] One side of the rotating shaft 16 is fixedly connected to a fixed roller 21, and one side of the mounting block 17 is fixedly connected to a connecting block 22. The connecting block 22 has a moving rod 23 inside, and one end of the moving rod 23 is fixedly connected to a locking block 24. The locking block 24 locks with the fixed roller 21. When the rotating shaft 16 drives the fixed roller 21 to rotate, the external protrusion of the fixed roller 21 will push the locking block 24. The locking block 24 will be forced to push the moving rod 23 to slide inside the connecting block 22, so that the moving rod 23 compresses the second spring 25, the fixed roller 21 stops rotating, and the locking block 24 will be locked with the fixed roller 21 by the rebound force of the second spring 25. This prevents the rotating shaft 16 from rotating due to the gravity of the Venetian blind body 12, making it convenient to use.

[0031] Specifically, the movable rod 23 is slidably connected to the connecting block 22. The connecting block 22 is equipped with a second spring 25, which is fixedly connected between one side of the movable rod 23 and the inside of the connecting block 22. The second spring 25 can easily restore the movable rod 23 to its original state, making it convenient to use.

[0032] Furthermore, a protective shell 26 is fixedly connected between the two sets of mounting blocks 17 by bolts. The protective shell 26 is set outside the connecting rod 11. The protective shell 26 can protect the connecting rod 11 and the Venetian blind body 12.

[0033] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
