Description

Technical Field

[0001] This utility model relates to the field of venetian blind technology, and more specifically, to a single-sided support and fixing device adapted to a venetian blind flipping mechanism. Background Technology

[0002] Venetian blinds, as a common sun-shading and decorative device, are widely used in various types of buildings. Their flipping mechanism is the key component that allows for flexible adjustment of the blind slat angles, while the support and fixing device is an important component that ensures the stable operation of the rotating shaft within the flipping mechanism.

[0003] Currently, the most common technology for supporting and fixing blind tilting mechanisms on the market is a structure with limiting parts on both sides of the support. While this design can meet the basic requirement of supporting the rotation of the axis to a certain extent, it has many obvious drawbacks.

[0004] On the one hand, the presence of limiting parts on both sides significantly increases the overall weight of the support. This not only causes inconvenience to operators during installation, increasing the difficulty and labor intensity of installation, but also, during long-term use, the heavy weight of the support itself will place an additional burden on the overall structure of the louvers, affecting their service life and stability.

[0005] On the other hand, the large contact area between the limiting parts on both sides and the rotating shaft leads to increased friction between the rotating shaft and the limiting parts during rotation. This increased friction not only makes the rotation of the rotating shaft less smooth, affecting the flexibility and precision of the louver blade angle adjustment, but also accelerates the wear of the rotating shaft and limiting parts, reducing the service life of the components and increasing later maintenance costs. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight single-sided support fixture that is compatible with the louver flipping mechanism.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention is further configured as follows: a fixing structure disposed on the louver, a rotating shaft disposed on the fixing structure, and a fixing iron bar connected to the rotating shaft; the fixing structure includes a support part, a limiting part, and a stop block; the support part has a pair and is respectively disposed on the top two sides of the louver; the limiting part is disposed on the top of the support part and is used to support the rotation of the rotating shaft; the stop block has a pair and is respectively disposed on the side of the rotating shaft, and both stop blocks are cylindrical structures, and each of the two stop blocks has a first positioning groove for the fixing iron bar to pass through, the shape of the first positioning groove fitting the outside of the fixing iron bar.

[0008] By adopting the above technical solution, the problem of the support part being too heavy and the friction between it and the rotating shaft being increased due to the limiting parts on both sides being set in the existing technology is solved. The solution achieves the effects of reducing the weight of the support part, reducing the rotational friction of the rotating shaft, and ensuring the stable installation and rotation of the rotating shaft.

[0009] The present invention is further configured such that: a pair of openings are provided on the side of the limiting part, and both openings are cuboid structures, and the corners of the openings are chamfered structures.

[0010] The present invention is further configured such that: the fixing structure also includes an abutment part; the abutment part is disposed on the outside of the rotating shaft, and the shape of the abutment part is a semi-fan-shaped structure.

[0011] The present invention is further configured such that: a winding groove is provided on the outer side of the rotating shaft, and the winding groove is a U-shaped opening structure, so that the wire can be wound through the U-shaped opening.

[0012] The present invention is further configured such that: a slot is provided at the top of the support part, and the slot has a kidney-shaped hole structure.

[0013] The present invention is further configured such that: a pair of discharge grooves are provided on the side of the rotating shaft, and both discharge grooves are circular hole structures, and the discharge grooves are located on the side of the winding groove.

[0014] The present invention is further configured such that: a circular column is provided on the side of the rotating shaft, and a semi-circular hole is provided in the middle of the circular column for the iron bar of the fixing device to pass through.

This achieves the effects of reducing the weight of the support, reducing the rotational friction of the rotating shaft, and ensuring the stable installation and rotation of the rotating shaft.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: Embodiment 1 includes a fixing structure 1 installed on a louver, a rotating shaft 2 installed on the fixing structure 1, and a fixing iron bar 3 connected to the rotating shaft 2. The fixing structure 1 includes a support part 11, a limiting part 12, and a stop block 13. The support part 11 has a pair and is respectively installed on the top two sides of the louver. The limiting part 12 is installed on the top of the support part 11 and is used to support the rotation of the rotating shaft 2. The stop block 13 has a pair and is respectively installed on the side of the rotating shaft 2. Both stop blocks 13 are cylindrical structures, and each of the two stop blocks 13 has a first positioning groove for the fixing iron bar 3 to pass through. The shape of the first positioning groove fits the outside of the fixing iron bar 3.

[0020] It should be noted that the fixing iron bar 3 is used to connect with the rope wheel drive mechanism in the louver, which is existing technology and will not be described in detail here. A second positioning groove is provided inside the rotating shaft 2, which is connected to and identical in shape to the first positioning groove, and is connected to the fixing iron bar 3. During installation, the support part 11 is first installed onto the louver using fasteners, and the distance between a pair of support parts 11 is preferably 400mm. To solve the problem in the prior art where the support part 11 has limiting parts 12 on both sides to support the rotation of the rotating shaft 2, resulting in a large overall weight of the support part 11 and increased friction with the rotating shaft 2, a circular mounting groove is provided at the top of the limiting part 12. This circular mounting groove is used to restrict and support the installation and rotation of the rotating shaft 2. The rotating shaft 2 can be quickly installed and rotated stably through the circular mounting groove at the top of the limiting part 12. After the rotating shaft 2 is installed through the circular mounting groove, the stop block 13 can be located beside the limiting part 12. At this time, when the rotating shaft 2 and the fixing iron bar 3 rotate, the stop block 13 can rotate synchronously. During this process, the stop 13 prevents the rotating shaft 2 from dislodging from the outside of the limiting part 12 when rotating. Furthermore, since the rotating shaft 2 is supported by the limiting part 12 on one side, friction between the rotating shaft 2 and the limiting part 12 is reduced during rotation. Also, since the limiting part 12 is a single-sided support located at the top of the support part 11, the weight of the support part 11 installed on the louver is reduced. This solves the problem in the prior art where the support part 11 has a large overall weight and increased friction with the rotating shaft 2 due to the limiting parts 12 on both sides, achieving the effects of reducing the weight of the support part 11, reducing the rotational friction of the rotating shaft 2, and ensuring stable installation and rotation of the rotating shaft 2.

[0021] See Figure 1 The limiting part 12 has a pair of openings 121 on its side, and both openings 121 are cuboid structures, and the corners of the openings 121 are chamfered.

[0022] Specifically, in order to reduce the weight of the limiting part 12 and improve its support effect, an opening 121 is provided on the side of the limiting part 12 to reduce the weight of both the limiting part 12 and the support part 11.

[0023] See Figure 1 The fixing structure 1 also includes an abutment part 14; the abutment part 14 is disposed on the outside of the rotating shaft 2, and the shape of the abutment part 14 is a semi-fan-shaped structure.

[0024] Specifically, a fixing part located below the abutment part 14 can be provided on the top of the support part 11. This fixing part is used to restrict the rotation of the abutment part 14. The abutment part 14 is fixedly connected to the rotating shaft 2, and can drive the abutment part 14 to rotate synchronously when the rotating shaft 2 rotates. After rotation, it can drive the abutment part 14 to contact the fixing part, and after contact, the rotating shaft 2 and the abutment part 14 stop rotating. It should be noted that the rotation angle of the rotating roller and the abutment part 14 is preferably ninety degrees, and the fixing iron bar 3 is connected to the rope wheel drive mechanism.

[0025] See Figure 1 The outer side of the rotating shaft 2 is provided with a winding groove 21, and the winding groove 21 has a U-shaped opening structure, so that the wire can be wound through the U-shaped opening.

[0026] Specifically, when using the rotating shaft 2, the yarn should first be wound through the winding groove 21. After winding, the yarn is then fixed to the rotating shaft 2 using a riveting device, and then the yarn is connected to the louvers. Thus, when the rotating roller rotates, it can drive the louvers to open and close.

[0027] See Figure 1 The top of the support part 11 is provided with a slot 111, and the slot 111 has a kidney-shaped hole structure.

[0028] Specifically, the top of the support part 11 has a kidney-shaped hole. When installing the support part 11 onto the louvers, the support part 11 should first be installed onto the louvers using fasteners when installing the rotating shaft 2 and the fixing iron strip 3. Then, the rotating shaft 2 and the fixing iron strip 3 should be assembled and installed. This allows the support part 11 to be quickly installed onto the louvers.

[0029] See Figure 1 A pair of discharge grooves 22 are provided on the side of the rotating shaft 2, and both discharge grooves 22 are circular hole structures, and both discharge grooves 22 are located on the side of the winding groove 21.

[0030] Specifically, when the retainer iron strip 3 needs to be installed, air can be discharged through the discharge groove 22 during the process of installing the retainer iron strip 3 into the interior of the rotating shaft 2. This reduces friction when the retainer label is installed in the second positioning groove inside the rotating shaft 2, improving the smoothness of the installation of the retainer iron strip 3 and the rotating shaft 2.

[0031] See Figure 1 A circular column 4 is provided on the side of the rotating shaft 2, and a semi-circular hole is provided in the middle of the circular column 4 for the fixing iron bar 3 to pass through.

[0032] Specifically, to ensure the stable rotation of the rotating shaft 2 on the limiting part 12, the circular column 4 can rotate along with the rotating shaft 2. It is important to note that the circular column 4 does not contact the limiting part 12, but maintains a distance from it. Furthermore, the limiting part 12 is not intended to support the rotation of the rotating shaft 2. This ensures that the circular column 4 keeps the rotating shaft 2 stable on the limiting part 12 during rotation of the rotating shaft 2 and the stop block 13.

[0033] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
