Description

Technical Field

[0001] This utility model relates to the field of roller blind accessories, specifically to an adjustable and fixed roller blind end plug. Background Technology

[0002] There are generally two installation methods for roller blinds: drilled installation and drill-free installation. Drilled installation involves fixing the blind to the wall on both sides of the window edge with screws. This type of installation is complex, requires additional tools, and involves drilling holes in the wall, damaging the wall surface. Furthermore, different wall types require different drilling tools, making installation complicated and cumbersome, and disassembly is inconvenient after installation. Drill-free installation, due to its non-destructive nature and ease of installation, is becoming increasingly popular in the market.

[0003] Most no-drill roller blinds on the market do not have adjustable width. A few no-drill roller blinds achieve this through a threaded structure, such as the installation accessories for a roller blind with a cover (application number 202122230961.X). This structure has problems such as the threads wearing out easily after repeated use, difficulty in tightening by hand, and being time-consuming and laborious; some even require a wrench to ensure a secure installation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable and fixed roller blind end plug. The roller blind end plug can be adjusted at multiple points through a multi-point adjustment component to adjust the distance between the end plate and the end plug, thereby adjusting the width of the roller blind.
