Description

Technical Field

[0001] This utility model relates to the field of curved Venetian blinds, and in particular to a left and right stretching device for curved Venetian blinds. Background Technology

[0002] Curved Venetian blinds are a type of curtain device featuring curved slats. They are typically made of materials such as plastic, wood, or metal. Their unique design allows them to create a curved effect on windows, adapting to non-linear window shapes or providing more decorative options. The angle of the slats can be adjusted to control the amount of light entering the room, effectively protecting privacy while maintaining ventilation. Their curved design adds beauty and personality to the space, enhancing the interior décor. The left and right extension mechanisms of curved Venetian blinds are mechanical structures installed on the sides or top of the blinds, typically consisting of pull cords, pulleys, and adjusters. These mechanisms are designed to adjust the opening and closing of the blinds and the angle of the slats to meet different lighting and privacy needs.

[0003] In existing technology, when installing curved Venetian blinds with tensioning devices in the corresponding positions, workers need to hold the other end and keep it horizontal while installing one end to improve the levelness of the installation. However, this increases the labor intensity of the workers and reduces the efficiency of the installation. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when using existing equipment, workers cannot ensure the horizontal installation of the curved venetian blind with a tensioning device, so a left and right tensioning device for the curved venetian blind is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a left and right stretching device for a curved Venetian blind, comprising a stretching device box, the bottom of which is provided with the curved Venetian blind body; mounting blocks are fixedly installed on the outer wall of the stretching device box; one side of the outer wall of the stretching device box contacts a window / wall mounting surface; two prefabricated blocks are fixedly installed on one side of the outer wall of the window / wall mounting surface; each of the two prefabricated blocks has a first limiting hole at its top; limiting blocks are movably inserted into the inner wall of each of the two first limiting holes, and both limiting blocks are L-shaped; and a strip-shaped insertion hole is provided on one side of the outer wall of each of the two prefabricated blocks. The outer walls of the two mounting blocks are movably inserted into the two strip-shaped insertion holes.

[0006] Preferably, the top of each of the two mounting blocks is provided with a second limiting hole, and the outer walls of the two limiting blocks are movably inserted into the interior of the two second limiting holes.

[0007] Preferably, a fixing hole is provided on one side of the outer wall of each of the two limiting blocks.

[0008] Preferably, the inner walls of the two fixing holes are threaded with fixing bolts, and the top of the tensioning device box has two strip-shaped slots.

[0009] Preferably, the inner surface of both strip-shaped slots is provided with strip-shaped blocks.

[0010] Preferably, a strip cover plate is fixedly installed between the tops of the two strip blocks.

[0011] Preferably, each of the two precast blocks has a circular hole on one side of its outer wall, and the outer walls of the two fixing bolts are movably inserted into the two circular holes.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when it is necessary to install a curved Venetian blind with a tensioning device box on a window wall mounting surface, two mounting blocks are inserted into two strip-shaped insertion holes, and then two limiting blocks are simultaneously inserted into two first limiting holes and two second limiting holes, which has a limiting effect on the curved Venetian blind with a tensioning device box, so that its two ends are always in a horizontal state. Then, through the action of two fixing bolts, it passes through two round holes and is fixed in two fixing holes, thus completing the installation. In addition, during the installation process, the labor intensity of the workers is reduced, thereby improving the installation efficiency.

[0014] 2. In this utility model, the strip cover plate is engaged in two strip slots by two strip blocks, which makes it easy to remove the strip cover plate and then inspect and maintain the internal components such as the pull rope, pulley and adjuster, thereby improving the service life.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a left and right stretching device for a curved Venetian blind, including a stretching device box 1. A curved Venetian blind body 2 is located at the bottom of the stretching device box 1. An installation block 3 is fixedly installed on the outer wall of the stretching device box 1. One side of the outer wall of the stretching device box 1 contacts a window / wall mounting surface 4. Two prefabricated blocks 5 are fixedly installed on one side of the outer wall of the window / wall mounting surface 4. Each of the two prefabricated blocks 5 has a first limiting hole 6 at its top. A limiting block 7 is movably inserted into the inner wall of each of the two first limiting holes 6, and both limiting blocks 7 are L-shaped. Each of the two prefabricated blocks 5 has a strip-shaped insertion hole 8 on one side of its outer wall. The outer walls of the two installation blocks 3 are movably inserted into the two strip-shaped insertion holes 8. Each of the two installation blocks 3 has a second limiting hole 9 at its top, and the outer walls of the two limiting blocks 7 are movably inserted into the two second limiting holes 9. Each of the two limiting blocks 7 has a fixing hole 10 on one side of its outer wall, and a fixing bolt 11 is threadedly connected to the inner wall of each fixing hole 10.

[0024] The overall effect of Embodiment 1 is that the curved Venetian blind body 2 is located at the bottom of the tensioning device box 1, and the tensioning device box 1 includes components such as pull ropes, pulleys, and adjusters. The curved Venetian blind can be moved up and down and the opening and closing degree of the blinds can be adjusted by the pull ropes on the left and right sides. When it needs to be installed on the window wall mounting surface 4, since there are mounting blocks 3 installed on both sides of the tensioning device box 1, and two prefabricated blocks 5 are installed on one side of the window wall mounting surface 4, and each of the two prefabricated blocks 5 has a strip-shaped insertion hole 8 on one side, when the tensioning device box 1 and the curved Venetian blind body 2 contact the window wall mounting surface 4, the mounting blocks 3 installed on both sides are exactly inserted into the strip-shaped insertion holes on the two prefabricated blocks 5. Within 8, since the top of each of the two precast blocks 5 has a first limiting hole 6 and the top of each of the two mounting blocks 3 has a second limiting hole 9, the T-shaped limiting block 7 is simultaneously inserted into the first limiting hole 6 and the second limiting hole 9, which has a limiting effect on the tensioning device box 1 and the curved venetian blind. When the workers fix it here, both ends are always in a horizontal state. Then, through the action of the two fixing bolts 11, it passes through the round holes 15 opened on the two precast blocks 5 and is threaded into the fixing holes 10 opened on the two limiting blocks 7, so that it is installed horizontally in the corresponding position. In addition, during the installation process, the labor intensity of the workers is reduced, thereby improving the installation efficiency.

[0025] Example 2: As Figures 2-4 As shown, the top of the stretching device box 1 has two strip-shaped slots 12, and the inner surface of each of the two strip-shaped slots 12 is provided with a strip-shaped block 13. A strip-shaped cover plate 14 is fixedly installed between the tops of the two strip-shaped blocks 13. A round hole 15 is provided on one side of the outer wall of each of the two precast blocks 5, and the outer surface of each of the two fixing bolts 11 is movably inserted into the two round holes 15.

[0026] The effect achieved by the entire embodiment 2 is that, since two strip-shaped slots 12 are opened on the top of the tensioning device box 1, the two strip-shaped blocks 13 installed at the bottom of the strip-shaped cover plate 14 are precisely engaged in the two strip-shaped slots 12, and external force is required to remove the strip-shaped cover plate 14. Therefore, when it is necessary to inspect and maintain the pull rope, pulley and adjuster and other components inside the tensioning device box 1, it is convenient to remove the strip-shaped cover plate 14, which facilitates inspection and maintenance, thereby improving the service life.

[0027] Working principle: First, when the curved Venetian blind with tensioning device box 1 needs to be installed on the window wall mounting surface 4, the mounting blocks 3 installed on both sides of the tensioning device box 1 are precisely inserted into the strip-shaped insertion holes 8 opened on the two prefabricated blocks 5. Then, the limiting blocks 7 are simultaneously inserted into the first limiting holes 6 opened on the two prefabricated blocks 5 and the second limiting holes 9 opened on the two mounting blocks 3. At this time, the tensioning device box 1 and the curved Venetian blind are limited. When the worker needs to install it in the corresponding position on the window wall mounting surface 4, both ends can always be in a horizontal state. Then, the two fixing bolts 11 are passed through the round holes 15 opened on the two prefabricated blocks 5 and then threaded into the inside of the two fixing holes 10. Thus, it can be installed horizontally in the corresponding position. During the installation process, the worker does not need to hold one end of the tensioning device box 1 with his hand, which reduces the fatigue of the worker and improves the efficiency of installing the curved Venetian blind with tensioning device box 1 in the corresponding position.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
