Description

Technical Field

[0001] This utility model relates to the field of curtain mounting bracket technology, specifically a mounting bracket for installing curtains without drilling. Background Technology

[0002] Currently, most curtains on the market, especially pleated blinds, honeycomb blinds, Venetian blinds, and Roman blinds, require professional in-home measurements to be taken and custom-made to fit the dimensions. After the curtains are made, professional installers are sent to install them. This results in significant costs in terms of manpower, financial resources, and materials. Moreover, installation typically requires screws to fix the curtains to the wall or curtain box, which can damage the wall or curtain box. If the wall is tiled, this can cause considerable damage to the tile surface, generate a lot of dust that pollutes the curtains and the indoor environment, and produce considerable installation noise that can disturb neighbors.

[0003] Most existing no-drill installation brackets on the market require shortening the top beam and fixing the bracket to the outer sides of both ends of the top beam. They do not hide the no-drill installation part inside the top beam track. After installation, a special cover is needed to cover the no-drill part. Even so, there will still be a height difference and color difference between it and the top beam, which will affect the overall appearance consistency of the curtains.

[0004] Meanwhile, existing no-drill structures range from simple, crude methods like direct nut and thread drive tightening to more sophisticated methods like bevel gear worm gear tightening or screw-and-linkage structures. The latter two methods require higher precision in component fitting, making mass production control more difficult. Most existing no-drill mounting brackets use an integrated design or shaft connection for the tightening push rod and support plate, which cannot accommodate wall surfaces with forward / backward or vertical tilting. Furthermore, most existing no-drill mounting brackets and end caps are integrated only with one type of curtain track, failing to provide compatibility with multiple tracks, thus reducing product versatility and requiring higher development costs. No solutions have yet been proposed to address these technical issues. Utility Model Content

[0005] In response to the problems in related technologies, this utility model proposes a no-drill curtain mounting bracket to overcome the aforementioned technical problems existing in the prior art. The purpose of this utility model is to effectively solve the problem that the unevenness and tilt of the existing curtain box and the wall surface make it difficult to install the no-drill mounting bracket. The structure is simple and reliable, the fitting precision requirements are low, it is easy to mass-produce, expands the range of minimum and maximum installation sizes, and reduces the light leakage problem caused by the no-drill mounting bracket to a certain extent.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mounting bracket for curtains that can be installed without drilling, comprising an upper beam, both ends of which are provided with end caps, an adjusting body connected to one side of each end cap, a steering wheel nut movably connected inside the adjusting body, an adjusting screw threaded onto the steering wheel nut, a drive gear movably connected to the adjusting body, the drive gear having an internal hexagonal hole, a through hole on the upper beam, an opening at one end of the adjusting screw, a compression spring inside the opening, a support plate on one side of the adjusting screw, a push rod connected to one end of the support plate, and one end of the push rod extending into the opening.

[0007] Preferably, a manual adjustment wheel is movably connected to the outer surface of the upper beam, and the manual adjustment wheel is fixedly connected to the drive gear.

[0008] Preferably, an internal hex wrench is provided on one side of the upper beam, with one end of the internal hex wrench passing through the through hole and extending into the interior of the internal hex hole.

[0009] Preferably, the manual adjustment wheel and the drive gear are fixedly connected by self-tapping screws.

[0010] Preferably, the upper beam is made of aluminum.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model is a mounting bracket for curtains that does not require drilling. By setting the steering wheel nut, adjusting screw and drive gear on the adjusting body, and adopting a separate design for the adjusting body and the end cap, the bracket can be designed to fit different curtain upper rails without replacing other structural components. This effectively solves the problem of difficult installation of the no-drill mounting bracket caused by unevenness and tilt of the curtain box and the wall. This utility model is a mounting bracket for curtains that does not require drilling. It uses an innovative irregularly shaped active drive gear and a driven steering wheel nut to vertically switch the transmission direction, thereby driving the adjusting screw to move back and forth. The structure is simple and reliable, with low precision requirements, and is easy to mass-produce. The main adjustment part is hidden inside the upper beam, and the upper beam and curtain form an integrated effect. The support plate is designed to be flush with the end cap by the design of the end cap, thereby expanding the minimum and maximum installation size range and reducing the light leakage problem caused by the no-drill mounting bracket to a certain extent.
