[0003] However, existing roller blinds are prone to damage when the curtain is blown by the wind because the lightweight hanging structure at the bottom of the curtain can easily collide with the glass. Furthermore, roller blinds can easily tilt after installation, failing to completely block the window and thus reducing their effectiveness. Therefore, we have proposed an adjustable and balanced anti-collision roller blind to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable and balanced anti-collision roller blind, which solves the problems of the lightweight structure hanging at the bottom of the curtain, which easily causes the structure to collide with the glass when the curtain is blown by the wind, thus easily leading to glass damage. Furthermore, after the roller blind is installed, the curtain is prone to tilting, thus failing to completely block the window and reducing the effectiveness of the blind.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable and balanced anti-collision roller curtain, comprising a mounting frame, sleeves on both sides of the inner cavity of the mounting frame, a roller inserted between the two sleeves, a curtain cloth wound around the middle of the roller, a pull cord on the roller and located on one side of the curtain cloth, a hanging assembly at the bottom end of the curtain cloth, the hanging assembly comprising a first slide rail, a first baffle and a second baffle respectively provided on the bottom sides of the first slide rail, a third baffle provided above the second baffle and located opposite the first baffle, the inner wall of the third baffle near the bottom end being connected to the inner wall of the second baffle near the top end via a second slide rail, an anti-collision strip inserted into the inner cavity of the second slide rail, and the anti-collision strip extending to the outside of the second baffle and the third baffle; A counterweight bar is inserted into the inner cavity of the first slide rail. The two sides of the bottom surface of the counterweight bar are respectively attached to the bottom of the inner wall of the first baffle and the second baffle. Mounting tubes are provided on both sides of the first slide rail near the top. The two mounting tubes are respectively connected to the first baffle and the second baffle. Both ends of the first slide rail are provided with sealing parts, and the sealing parts are connected to the mounting tube. A rotating tube is movably inserted between the two sealing parts.

[0006] Preferably, the first slide rail, the first baffle, the second baffle, the third baffle, and the second slide rail are all made of the same material.

[0007] Preferably, one end of the anti-collision strip has a first through hole, and the first through hole extends to the other end of the anti-collision strip.

[0008] Preferably, the length of the anti-collision strip is the same as the length of the second slide rail, and the length of the first slide rail is greater than the length of the counterweight strip.

[0009] Preferably, the sealing part includes a cap, and a limiting post for inserting the rotating tube is provided at the middle of the inner wall of the cap near the mountain. The inner wall of the cover is provided with a second through hole on both sides, and a positioning screw is inserted into the inner cavity of each of the two second through holes. One end of the positioning screw is rotatably connected to the inner cavity of the mounting tube.

[0010] Preferably, the outer diameter of the limiting post is the same as the inner diameter of the rotating tube, and the two are connected by insertion.

[0011] Preferably, the mounting tube has a C-shaped front view. Beneficial effects

[0012] This invention provides an adjustable and balanced anti-collision roller blind. Compared with the prior art, it has the following advantages: This adjustable and balanced anti-collision roller blind can be installed in a designated position via a mounting bracket, or the roller can be installed via two sleeves. The roller can both wind the curtain fabric and facilitate the installation of the pull cord. Pulling the pull cord synchronously drives the roller to rotate, thereby allowing the roller to rewind the curtain fabric. The first slide rail connects the first and second baffles into a whole, and the second baffle can be connected to the third baffle via the second slide rail, thus forming a U-shaped structure. Since both ends of the U-shaped structure are equipped with sealing parts, and the inner walls of the first and second baffles are provided with mounting tubes for installing the sealing parts, the two sealing parts can be installed under the action of the two mounting tubes, so that the two sealing parts can seal the two ends of the U-shaped structure. Since a rotating tube is movably connected between the two sealing parts, and the bottom end of the curtain is fitted onto the rotating tube of the hanging assembly, the two sealing parts can be moved up or down via the rotating tube by the roller winding or unfolding the curtain, thereby moving the entire hanging assembly up or down. At this time, the hanging assembly acts as a counterweight for the curtain. Since an anti-collision strip is inserted into the inner cavity of the second slide rail, and the anti-collision strip extends to the outside of the second baffle and the third baffle, the anti-collision strip can reduce the impact of the hanging assembly on the window glass, thereby effectively protecting the safety of the glass. Since a counterweight is inserted into the inner cavity of the first slide rail, and the two sides of the bottom surface of the counterweight are respectively attached to the bottom of the inner wall of the first baffle and the second baffle, the counterweight can be moved and adjusted when the curtain deviates during lifting and lowering, thereby changing the center of the curtain and thus achieving the effect of correcting the deviation of the curtain.

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7 This utility model provides a technical solution: an adjustable and balanced anti-collision roller blind, including a mounting frame 11. Sleeves 12 are provided on both sides of the inner cavity of the mounting frame 11. A roller 13 is inserted between the two sleeves 12. A curtain fabric 14 is wound around the middle of the roller 13. A pull cord 15 is provided on the roller 13 and on one side of the curtain fabric 14. A hanging assembly is provided at the bottom end of the curtain fabric 14. The hanging assembly includes a first slide rail 1. A first baffle 2 and a second baffle 3 are respectively provided on both sides of the bottom of the first slide rail 1. A third baffle 4 is provided above the second baffle 3 and opposite to the first baffle 2. The inner wall of the third baffle 4 near the bottom is open... The second slide rail 5 is connected to the inner wall of the second baffle 3 near the top. The inner cavity of the second slide rail 5 is fitted with a collision strip 6, which extends to the outer side of the second baffle 3 and the third baffle 4. The inner cavity of the first slide rail 1 is fitted with a counterweight 7, the bottom surface of which is attached to the bottom of the inner wall of the first baffle 2 and the second baffle 3 on both sides. The first slide rail 1 is provided with mounting tubes 8 on both sides near the top, which are connected to the first baffle 2 and the second baffle 3 respectively. The first slide rail 1 is provided with a sealing part 9 at both ends, which is connected to the mounting tube 8. A rotating tube 10 is movably inserted between the two sealing parts 9. The mounting bracket 11 allows for installation in a designated location and also enables the installation of the roller 13 via two sleeves 12. The roller 13 facilitates both winding the curtain fabric 14 and installing the pull cord 15. Pulling the pull cord 15 synchronously rotates the roller 13, allowing it to wind up the curtain fabric 14. The first slide rail 1 connects the first baffle 2 and the second baffle 3 into a single unit, and the second baffle 3 is connected to the third baffle 4 via the second slide rail 5, forming a U-shaped structure. Since both ends of the U-shaped structure are equipped with sealing parts 9, and the inner walls of the first baffle 2 and the second baffle 3 are provided with mounting tubes 8 for installing the sealing parts 9, the two sealing parts 9 can be installed under the action of the two mounting tubes 8, effectively sealing both ends of the U-shaped structure. A rotating tube is movably inserted between the two sealing parts 9. 10. The bottom end of the curtain 14 is fitted onto the rotating tube 10 of the hanging assembly. Therefore, by rolling up or unrolling the curtain 14 through the roller 13, the two sealing parts 9 can be moved up or down through the rotating tube 10, thereby moving the entire hanging assembly up or down. At this time, the hanging assembly acts as a counterweight for the curtain 14. Since the anti-collision strip 6 is inserted into the inner cavity of the second slide rail 5 and extends to the outside of the second baffle 3 and the third baffle 4, the anti-collision strip 6 can reduce the impact of the hanging assembly on the window glass, thereby effectively protecting the safety of the glass. Since the counterweight strip 7 is inserted into the inner cavity of the first slide rail 1 and the two sides of the bottom surface of the counterweight strip 7 are respectively attached to the bottom of the inner wall of the first baffle 2 and the second baffle 3, when the curtain 14 deviates during lifting and lowering, the counterweight strip 7 can be moved and adjusted, thereby changing the center of the curtain 14 and thus correcting the deviation of the curtain 14.

[0017] See Figures 3-5 The first slide rail 1, the first baffle 2, the second baffle 3, the third baffle 4, and the second slide rail 5 are all made of the same material, which makes it easy to connect the first slide rail 1, the first baffle 2, the second baffle 3, the third baffle 4, and the second slide rail 5 together.

[0018] See Figure 5 , Figure 6 One end of the anti-collision strip 6 has a first through hole, and the first through hole extends to the other end of the anti-collision strip 6, which can reduce the weight of the anti-collision strip 6 and also play a role in collision buffering.

[0019] See Figure 4 , Figure 5 The length of the anti-collision strip 6 is the same as the length of the second slide rail 5, which can prevent the anti-collision strip 6 from swinging during use. The length of the first slide rail 1 is greater than the length of the counterweight strip 7, which allows the user to easily adjust the position of the counterweight strip 7 on the first slide rail 1.

[0020] See Figure 5 , Figure 8 The sealing part 9 includes a cover 91. A limiting post 92 for inserting the rotating tube 10 is provided at the middle of the inner wall of the cover 91 near the mountain. A second through hole 93 is provided on both sides of the inner wall of the cover 91. A positioning screw 94 is inserted into the inner cavity of each of the two second through holes 93. One end of the positioning screw 94 is rotatably connected to the inner cavity of the mounting tube 8. The outer diameter of the limiting post 92 is the same as the inner diameter of the rotating tube 10, and the two are inserted and connected. The cap 91 in the sealing part 9 can seal one end of the U-shaped structure and can also be inserted into the rotating tube 10 via the limiting post 92, so that the rotating tube 10 can rotate flexibly on the limiting post 92. Furthermore, the positioning screw 94 can pass through the second through hole 93 and be installed on the mounting tube 8, so as to fix the cap 91 and improve the stability of the cap 91 after installation.

[0021] See Figure 5 The main view of the installation tube 8 is C-shaped, which facilitates the installation of the positioning screw 94 on the sealing part 9.

[0022] During operation, the mounting bracket 11 can be used to install the curtain fabric 14 in a designated position, and the roller 13 can be installed via the two sleeves 12. The roller 13 can be used to wind the curtain fabric 14 and also facilitates the installation of the pull cord 15. Pulling the pull cord 15 synchronously rotates the roller 13, allowing it to wind up the curtain fabric 14. The first slide rail 1 connects the first baffle 2 and the second baffle 3 into a single unit, and the second baffle 3 can be connected to the third baffle 4 via the second slide rail 5, thus forming a U-shaped structure. Since both ends of the U-shaped structure are equipped with sealing parts 9, and the inner walls of the first baffle 2 and the second baffle 3 are provided with mounting tubes 8 for installing the sealing parts 9, the two sealing parts 9 can be installed under the action of the two mounting tubes 8, allowing them to seal both ends of the U-shaped structure. A rotating mechanism connects the two sealing parts 9. The bottom end of the curtain 14 is fitted onto the rotating tube 10 of the hanging assembly. Therefore, by winding or unwinding the curtain 14 through the roller 13, the two sealing parts 9 can be moved up or down through the rotating tube 10, thereby moving the entire hanging assembly up or down. At this time, the hanging assembly acts as a counterweight for the curtain 14. Since the anti-collision strip 6 is inserted into the inner cavity of the second slide rail 5 and extends to the outside of the second baffle 3 and the third baffle 4, the anti-collision strip 6 can reduce the impact of the hanging assembly on the window glass, thereby effectively protecting the safety of the glass. Since the counterweight strip 7 is inserted into the inner cavity of the first slide rail 1 and the two sides of the bottom surface of the counterweight strip 7 are respectively attached to the bottom of the inner wall of the first baffle 2 and the second baffle 3, when the curtain 14 deviates during lifting and lowering, the counterweight strip 7 can be moved and adjusted, thereby changing the center of the curtain 14 and thus correcting the deviation of the curtain 14.

[0023] The cap 91 in the sealing part 9 can seal one end of the U-shaped structure and can also be inserted into the rotating tube 10 via the limiting post 92, so that the rotating tube 10 can rotate flexibly on the limiting post 92. Furthermore, the positioning screw 94 can pass through the second through hole 93 and be installed on the mounting tube 8, so as to fix the cap 91 and improve the stability of the cap 91 after installation.

[0024] In summary, this device can reduce the impact of the bottom hanging structure of the curtain 14 on the glass through the anti-collision strip 6, and can also move and adjust the counterweight strip 7 when the curtain 14 is raised or lowered off-center, thereby changing the center of the curtain 14 and thus correcting the deviation of the curtain 14.
