Description

Technical Field

[0001] This utility model relates to the field of curtain components, specifically to a telescopic tensioning device that does not require drilling. Background Technology

[0002] Curtains generally consist of a curtain rod and curtain slats. There are generally two installation methods: drilled grommet installation and no-drill installation. No-drill installation is becoming increasingly popular due to its ease of installation and lack of wall damage. It utilizes a no-drill installation mechanism on the curtain track to install curtains and other products onto window frames, door frames, or other suitable locations.

[0003] Most commercially available no-drill curtain products use a threaded structure. For example, a no-drill installation support structure (application number 202321774187.1) includes a mounting shell with a mounting groove at one end and an adjustment cavity at the other end. A slidable top block is located within the mounting groove, and an adjustment component is connected to the adjustment cavity. The adjustment component is connected to a linkage screw, which passes through the adjustment cavity and connects to the top block. This worm gear structure suffers from several drawbacks: the threads wear easily after repeated use, making it difficult to tighten by hand, sometimes requiring a wrench for secure installation; furthermore, its large lateral space makes it unsuitable for thin curtains. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a telescopic tensioning device that eliminates the need for drilling curtain rods. This device is not easily worn, does not present problems such as difficulty in hand-twisting, and greatly reduces its usability. It is suitable not only for ordinary curtains but also for any thin curtains.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A telescopic, non-drilling tensioning device includes a mounting base installed on a curtain rod, a sliding block that slides relative to the mounting base, and a threaded rod that passes through the mounting base on at least one side. The threaded rod is provided with a driving block, which is threadedly connected to the threaded rod. The driving block is rotatably connected to a support rod. When the threaded rod is rotated, the driving block moves along the length of the threaded rod, causing the support rod to abut against the sliding block and slide relative to the mounting base.

[0007] Preferably, the threaded rod is a bidirectional threaded rod, and there are two sets of driving blocks. The two sets of driving blocks are respectively installed on the bidirectional threads of the threaded rod. There are two sets of support rods, and the two sets of support rods are arranged in an X-shape. A rotating shaft is provided at their intersection. When the threaded rod is rotated, the two sets of driving blocks move towards or away from each other, causing the two sets of support rods to rotate relative to the rotating shaft.

[0008] Preferably, the sliding block is provided with a long sliding groove, and the end of the support rod away from the drive block is provided with a protrusion. When the two sets of support rods rotate in a cross manner, the protrusion moves along the length of the long sliding groove.

[0009] Preferably, a slider seat is sleeved on the outer side of the slider block, and an end plate is provided on one side of the slider seat. The slider seat slides toward the mounting seat until the end plate abuts against the mounting seat.

[0010] Preferably, the mounting base includes a housing and a cover that engages with the housing. The cover has a raised plate, and the slider seat has an elongated hole. The raised plate slides within the elongated hole to limit the sliding direction of the slider seat.

[0011] Preferably, the cover is provided with a mounting groove for the threaded rod to install and support the threaded rod.

[0012] Preferably, the end plate is equipped with anti-slip components.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The tensioning device of this invention eliminates the need for drilling curtain rods, is not easily worn, and avoids problems such as difficulty in hand-twisting. It also greatly reduces the space required for its use and is suitable not only for ordinary curtains but also for any thin curtains. Attached Figure Description

Detailed Implementation

[0022] Example 1: A preferred embodiment of the present invention provides a telescopic tensioning device without drilling, including a mounting base 2 installed on a curtain rod 1, a sliding block 3 that slides relative to the mounting base 2, and a threaded rod 4 that passes through the mounting base 2 on at least one side. The threaded rod 4 is provided with a driving block 5, which is threadedly connected to the threaded rod 4. The driving block 5 is rotatably connected to a support rod 6.

[0023] The threaded rod 4 is in a one-way threaded rod state. It can also be used in conjunction with a set of drive blocks 5 and a set of support rods 6. That is, when the threaded rod 4 is rotated, the set of drive blocks 5 moves along the length of the threaded rod 4, driving the set of support rods 6 to rotate along the rotation axis 7 and resist the sliding block 3 relative to the mounting base 2.

[0024] In the preferred embodiment, the threaded rod 4 is a bidirectional threaded rod, and there are two sets of driving blocks 5. The two sets of driving blocks 5 are respectively installed on the bidirectional threads of the threaded rod 4. There are two sets of support rods 6. The two sets of support rods 6 are arranged in an X-shape and a rotating shaft 7 is provided at their intersection. When the threaded rod 4 is rotated, the two sets of driving blocks 5 move towards or away from each other, causing the two sets of support rods 6 to rotate relative to the rotating shaft 7.

[0025] The sliding block 3 is provided with a long sliding groove 31, and the support rod 6 is provided with a protrusion 61 at the end away from the drive block 5. When the two sets of support rods 6 rotate in a cross direction, the protrusion 61 moves along the length of the long sliding groove 31.

[0026] This tensioning device eliminates the need for drilling curtain rods, is not easily worn, and avoids problems such as difficulty in hand-tightening. It uses only one set of threaded rods 4, and the sliding block 3, threaded rod 4, drive block 5, and other structures used with the threaded rod 4 are all set along the width direction of the threaded rod 4, which greatly reduces its usable space. It is suitable not only for ordinary curtains but also for any thin curtains.

[0027] Example 2: A preferred embodiment of this utility model provides a telescopic tensioning device without drilling, which differs from the above embodiment only in that: a slider seat 8 is sleeved on the outside of the sliding block 3, an end plate 81 is provided on one side of the slider seat 8, the slider seat 8 slides toward the mounting seat 2 until the end plate 81 abuts against the mounting seat 2, and an anti-slip component 9 is installed on the end plate 81.

[0028] Example 3: A preferred embodiment of this utility model provides a telescopic tensioning device without drilling, which differs from the above embodiment only in that: the mounting base 2 includes a base shell 21 and a cover 22 that snaps into the base shell 21. The base shell 21 and the cover 22 are detachable, which facilitates the installation of structures such as the sliding block 3, the threaded rod 4, and the driving block 5. The cover 22 is provided with a protruding plate 23, and the slider seat 8 is provided with an elongated hole 82. The protruding plate 23 slides in the elongated hole 82 to limit the sliding direction of the slider seat 8. The cover 22 is provided with an installation groove 24 for the threaded rod 4 to install and support the threaded rod 4.

[0029] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
