Description

Technical Field

[0001] This utility model relates to the field of louver technology, and in particular to a louver that is easy to install. Background Technology

[0002] Venetian blinds are window coverings consisting of many adjustable blinds arranged horizontally or vertically. They are usually made of metal, wood, plastic, or fabric, and their opening degree can be adjusted by rotating or moving them up and down, thereby controlling indoor light and ventilation. Venetian blinds are widely used in offices, residences, and commercial spaces.

[0003] Most venetian blinds require pre-treatment such as drilling holes and applying adhesive to the wall during installation. This not only requires professional skills and tools but also involves complicated installation steps and damage to the wall. Over time, the drilled or adhesive areas may crumble or powder, and in severe cases, the blinds may even fall off due to moisture. In response to this technical problem, this application proposes a venetian blind that is easy to install. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a louver that is easy to install. By first snapping two mounting frames onto the wall and connecting and fixing them with bolts, the subsequent installation of the louver can be carried out inside the mounting frames without drilling holes or gluing the wall. Moreover, the louver can be disassembled simply by removing the bolts used to fix the two mounting frames, which is very convenient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An easy-to-install louver includes a wall and slats. Mounting frames are snapped onto the front and rear sides of the inner wall of the wall. A window frame is snapped onto the inner wall of each mounting frame. A mounting plate is provided at the front end of the wall. An upper track is provided on the inner wall of the top of the window frame. Enclosures are snapped onto both ends of the upper track. The outer walls of the enclosures are snapped onto the inner wall of the window frame. A drive assembly is provided on the right side of the inner wall of the upper track. A pull rope is connected to the left side of the inner wall of the upper track via a first control assembly. Traction ropes are connected to the left and right sides of the inner wall via a second control assembly.

[0006] Furthermore, the two mounting frames are connected by bolts, and the mounting plate is mounted on the front end of the mounting frame by bolts.

[0007] Furthermore, the drive assembly includes a fixed seat fixedly connected to the right side of the inner wall of the upper track, a worm gear rotatably connected to the inner wall of the bottom end of the fixed seat, and a control rod provided at the bottom end of the worm gear.

[0008] Furthermore, the first control component includes a guide seat fixedly connected to the left side of the inner wall of the upper track, a first guide roller rotatably connected to the front end of the guide seat, and the outer wall of the pull rope wrapped around the outer wall of the first guide roller.

[0009] Furthermore, a sliding groove is provided on the left side of the front end of the guide seat, and a limit roller is provided on the inner wall of the sliding groove.

[0010] Furthermore, the second control component includes a fixed frame fixedly connected to both the left and right sides of the inner wall of the upper track. A rotating shaft is provided on the inner wall of the top of the fixed frame. Rope winders are fixedly connected to both the left and right sides of the outer wall of the rotating shaft. A worm gear is fixedly connected to the right side of the outer wall of the rotating shaft. A second guide roller is rotatably connected to the inner wall of the fixed frame.

[0011] Furthermore, the right end of the rotating shaft is rotatably connected to the left end of the fixed base, and traction ropes are clamped to the inner wall of the top of the rope winder. The worm gear and the worm are meshed together.

[0012] Furthermore, both the upper track and the bottom of the guide seat are provided with through holes for the traction rope, the pull rope and the fixing seat to pass through. The outer wall of the pull rope is set on the outer wall of the second guide roller. The traction rope and the pull rope are connected by a rope body and the rope body is set inside the blade.

[0013] This utility model has the following beneficial effects: In this invention, two mounting frames are first snapped onto the wall and then connected and fixed with bolts. This allows the subsequent installation of the blinds to be carried out inside the mounting frames, eliminating the need for drilling or gluing into the wall. Furthermore, disassembly is very convenient; simply removing the bolts that secure the two mounting frames is sufficient to disassemble the entire blind.

[0014] In this invention, after the mounting plate is removed from the mounting frame, the upper track can be directly taken out from inside the window frame. Then, the traction rope and pull rope on the rope winder and the first guide roller can be untied and replaced directly, thereby enabling the replacement of damaged blades individually without replacing the entire louver, thus saving maintenance costs.

[0018] Reference Figure 1-3 An embodiment of this utility model provides: a louver that is easy to install, including a wall 1 and blades 5. The inner wall of the wall 1 is fitted with mounting frames 2 on both the front and rear sides. The inner wall of the mounting frames 2 is fitted with a window frame 6. The front end of the front wall 1 is provided with a mounting plate 3. The two mounting frames 2 are connected by bolts. The mounting plate 3 is installed at the front end of the mounting frames 2 by bolts. The top inner wall of the window frame 6 is provided with an upper track 4. The left and right ends of the upper track 4 are fitted with covers 10. The outer walls of the covers 10 are fitted with the inner walls of the window frame 6. The right side of the inner wall of the upper track 4 is provided with a drive assembly. The drive assembly includes a fixed seat 15 fixedly connected to the right side of the inner wall of the upper track 4. The bottom inner wall of the fixed seat 15 is rotatably connected with a worm gear 21. The bottom end of the worm gear 21 is provided with a control rod 7. Specifically, during installation, the two mounting frames 2 are first clipped onto the two sides of the wall 1, and then assembled using tools and bolts. Next, the window frame 6 is clipped into the assembled mounting frame 2, and the mounting plate 3 is clipped into the remaining groove at the front end of the mounting frame 2. Bolts are inserted into the four corners of the mounting plate 3, and tools are used to turn the bolts into the front mounting frame 2, thus installing the mounting plate 3 onto the mounting frame 2 and limiting the window frame 6 clipped into the mounting frame 2, completing the installation of the louver. This window does not require drilling into the wall 1 during installation, avoiding damage to the wall 1. Furthermore, disassembly is very convenient; simply removing the bolts used to fix the two mounting frames 2 is sufficient to disassemble the entire window.

[0019] Reference Figure 3 and Figure 4A pull rope 9 is connected to the left side of the inner wall of the upper track 4 via a first control component. The first control component includes a guide seat 11 fixedly connected to the left side of the inner wall of the upper track 4. A first guide roller 17 is rotatably connected to the front end of the guide seat 11. The pull rope 9 is wrapped around the outer wall of the first guide roller 17. A sliding groove 18 is provided on the left side of the front end of the guide seat 11. A limit roller 16 is provided on the inner wall of the sliding groove 18. Traction ropes 8 are connected to the left and right sides of the inner wall via a second control component. The second control component includes a fixed frame 12 fixedly connected to both the left and right sides of the inner wall of the upper track 4. A rotating shaft 14 is provided on the inner wall of the top of the fixed frame 12. Rope winders 13 are fixedly connected to both sides of the outer wall of shaft 14. Worm gear 20 is fixedly connected to the right side of the outer wall of shaft 14. Second guide rollers 19 are rotatably connected to the inner wall of fixed frame 12. The right end of shaft 14 is rotatably connected to the left end of fixed seat 15. Traction rope 8 is clamped to the inner wall of the top of rope winder 13. Worm gear 20 and worm 21 are meshed. Through holes are opened at the bottom of upper track 4 and guide seat 11 for traction rope 8, pull rope 9 and fixed seat 15 to pass through. Pull rope 9 is set on the outer wall of second guide roller 19. Traction rope 8 and pull rope 9 are connected by rope body and the rope body is set inside blade 5. If the blade 5 in the window is damaged, the mounting plate 3 can be removed from the mounting frame 2. Then, the cover 10 can be pulled to remove the upper track 4 from the inside of the window frame 6. Then, the traction rope 8, the pull rope 9 and the blade 5 inside the upper track 4 can be replaced individually. There is no need to replace the entire window. The surface of the limiting roller 16 is provided with a rough texture to increase its friction when it contacts the pull rope 9. This allows the pull rope 9 to contact the limiting roller 16 and move on the first guide roller 17, which can drive the limiting roller 16 to move inside the sliding groove 18 and cooperate with the first guide roller 17 to clamp and limit the pull rope 9. The second guide roller 19 inside the fixing frame 12 can provide guidance for the pull rope 9 during the adjustment process. The top of the rope winder 13 is hinged to a cover. The traction rope 8 can be fixed on the rope winder 13 through the cover to drive its movement. When replacing the traction rope 8, simply open the cover to replace it.

[0020] Working principle: During installation, the two mounting frames 2 are first clipped onto both sides of the wall 1, and then assembled using tools and bolts. Next, the window frame 6 is inserted into the assembled mounting frame 2. Then, the mounting plate 3 is inserted into the remaining groove at the front end of the mounting frame 2. Bolts are inserted into the four corners of the mounting plate 3, and tools are used to turn the bolts into the front mounting frame 2, thus installing the mounting plate 3 onto the mounting frame 2 and limiting the position of the window frame 6 inserted into the mounting frame 2. This completes the installation of the venetian blind. No drilling is required in the wall 1 during the installation process. This design avoids damage to the wall 1, and disassembly is very convenient; simply remove the bolts securing the two mounting frames 2 to complete the overall disassembly. If the slats 5 in the window are damaged, the mounting plate 3 can be removed from the mounting frame 2, and then the cover 10 can be pulled to remove the upper track 4 from inside the window frame 6. The traction rope 8, pull rope 9, and slats 5 inside the upper track 4 can then be replaced individually without replacing the entire window. During normal use, when adjusting the light transmission of the blinds, the user can rotate the control lever 7 to drive the worm gear 2. 1. Rotation drives the worm gear 20 to rotate, causing the rotating shaft 14 to rotate synchronously. The rotating shaft 14 drives the rope winders 13 on the left and right sides of its outer wall to rotate, causing the traction rope 8 to rise on one side and fall on the other. Since the traction rope 8 and the pull rope 9 are connected by a rope body and the rope body is set inside the blade 5, the traction rope 8 will drive the blade 5 to rotate, thereby adjusting the light transmission of the venetian blinds. To adjust the opening and closing degree of the venetian blinds, the pull rope 9 can be pulled directly to make the pull rope 9 drive the blade 5 to rise for retraction. After retraction, pull the pull rope 9 to the left so that the outer wall of the pull rope 9 is flush with the blade. When the pull rope 9 is released, it will move under the gravity of the blade 5. The friction between the pull rope 9 and the pull rope 16 will cause the pull rope 16 to move along the sliding groove 18 until it cooperates with the first guide roller 17 to clamp the pull rope 9 and complete the limit. At this time, the fan blade will be controlled and will no longer fall to complete the storage. When unfolding, first pull the pull rope 9 to the right so that the pull rope 9 is no longer in close contact with the pull rope 16. Then the pull rope 16 will slide down along the sliding groove 18 and reset under its own gravity. At this time, after releasing the pull rope 9, the blade 5 will fall under its own gravity and unfold.
