Description

Technical Field

[0001] This utility model relates to the field of curtain rod technology, specifically a drilling-free double telescopic rod roller blind fixing bracket. Background Technology

[0002] Roller blinds are a common indoor sunshade or privacy protection device, widely used in homes, offices and commercial spaces.

[0003] Traditional roller blinds typically require drilling holes directly into walls, window frames, or ceilings using screws or other fasteners. While this method offers structural stability, it has several drawbacks in practical applications. Drilling can cause irreversible damage to the building structure, making it particularly difficult to implement in rented properties or locations where alteration to the existing decor is not permitted. Furthermore, the installation process is cumbersome, requiring tools such as electric drills, demanding a certain level of user skill, and leaving holes after disassembly, which affects the aesthetics. Utility Model Content

[0008] Two telescopic rods are installed on the left and right sides of the window or floor-to-ceiling window, respectively, with the upper and lower ends of the two telescopic rods tightly fitted to the indoor ceiling and floor, respectively.

[0009] Two connecting rod sleeves are respectively installed on the two telescopic rods;

[0010] Four pole caps are respectively installed at the upper and lower ends of the two telescopic poles;

[0011] The retractable roller blind frame is fixedly installed at the upper end of two telescopic rods.

[0012] Preferably, the telescopic rod includes a track rod, a movable rod is slidably connected inside the track rod, an external threaded connecting block is fixedly connected to the upper end of the movable rod, and a plastic nut is threaded onto the external threaded connecting block.

[0013] Preferably, a connecting rod sleeve is fixedly connected to the lower outer wall of the track rod, and the lower end of the connecting rod sleeve is movably connected to the movable rod.

[0014] Preferably, the upper ends of the two track rods are fixedly connected to the left and right ends of the beaded telescopic roller blind frame, respectively, via connecting clips.

[0016] Beneficial effects

[0017] Compared with the prior art, this utility model provides a punch-free double telescopic rod roller blind fixing frame, which has the following advantages:

[0018] This utility model involves two movable rods fixedly connected to the left and right ends of a beaded retractable roller blind frame, which move up and down within two track rods.

[0025] 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.

[0026] Specific implementation examples are given below.

[0027] Example

[0028] Please see Figure 1 This utility model provides a punch-free double telescopic rod roller blind fixing bracket, comprising:

[0029] Two telescopic rods 1 are respectively installed on the left and right sides of the window or floor-to-ceiling window, and the upper and lower ends of the two telescopic rods 1 are tightly fitted to the indoor ceiling and floor respectively;

[0030] Two connecting rod sleeves 2 are respectively installed on two telescopic rods 1;

[0031] Four pole caps 3 are respectively installed at the upper and lower ends of the two telescopic poles 1;

[0032] The beaded telescopic roller shutter frame 5 is fixedly installed at the upper ends of the two telescopic rods 1;

[0033] Specifically, the two telescopic rods 1 are used to fix the beaded telescopic roller shutter frame 5.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the telescopic rod 1 includes a track rod 101, a movable rod 104 is slidably connected inside the track rod 101, an external threaded connecting block 102 is fixedly connected to the upper end of the movable rod 104, and a plastic nut 103 is threadedly connected to the external threaded connecting block 102.

[0035] Specifically, the movable rod 104 moves up and down within the track rod 101 to adjust the length of the telescopic rod 1. Rotating the movable rod 104 causes the external threaded connecting block 102 to rotate within the plastic nut 103, adjusting the expansion of the plastic nut 103 and the friction between the plastic nut 103 and the inner wall of the track rod 101.

[0036] like Figure 1 and Figure 2 As shown, a connecting rod sleeve 2 is fixedly connected to the lower outer wall of the track rod 101, and the lower end of the connecting rod sleeve 2 is movably connected to the movable rod 104.

[0037] Specifically, the connecting rod sleeve 2 shields the connection between the track rod 101 and the movable rod 104.

[0038] like Figure 1 and Figure 2 As shown, the upper ends of the two track rods 101 are fixedly connected to the left and right ends of the beaded telescopic roller blind frame 5 by connecting clips.

[0039] Specifically, the two track rods 101 provide fixed support for the beaded telescopic roller shutter frame 5.

[0040] like Figure 1 and Figure 2 As shown, the lower ends of the two movable rods 104 are respectively threaded with adjusting heads 105, the upper ends of the two track rods 101 are respectively fixedly connected with rod caps 3, the lower ends of the two adjusting heads 105 are respectively rotatably connected with rod caps 3, and the far ends of the two rod caps 3 on the left and the two rod caps 3 on the right are respectively fixedly connected with rubber pads 4.

[0041] Specifically, the rubber pads 4 fixedly installed on each pole cap 3 increase the friction between the upper and lower ends of the telescopic pole 1 and the indoor ceiling and floor. Rotating the adjusting head 105 can finely adjust the friction between the rubber pads 4 and the indoor ceiling and floor, thus improving the stability of the telescopic pole 1 installation.

[0042] Working principle: When using this roller shutter fixing frame, first rotate the movable rod 104 to drive the external threaded connecting block 102 to rotate inside the plastic nut 103, causing the plastic nut 103 to contract, reducing the friction between the plastic nut 103 and the inner wall of the track rod 101. This pulls the two movable rods 104 to slide up and down inside the two track rods 101 respectively, thereby causing the two upper rod caps 3 and rubber pads 4 to move towards or away from the two lower rod caps 3 and rubber pads 4, so that the two upper rubber pads 4 and the two lower rubber pads 4 respectively contact the interior... The inner top surface and the ground are tightly fitted together. Then, the movable rod 104 is rotated in the opposite direction to drive the external threaded connecting block 102 to rotate in the opposite direction inside the plastic nut 103, causing the plastic nut 103 to expand and increase the friction between the plastic nut 103 and the inner wall of the track rod 101, preventing the track rod 101 and the movable rod 104 from loosening. Rotating the adjusting head 105 can finely adjust the friction between the rubber pad 4 and the indoor top surface and ground, limiting and fixing the two track rods 101 and the two movable rods 104, and then installing the beaded telescopic roller blind frame 5.

[0043] 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.
