A portable shade screen

Abstract

This utility model provides a portable blackout curtain, including a supporting shell and a blackout curtain. The blackout curtain is detachably connected to the supporting shell. Both ends of the supporting shell have first sliding grooves, and a rotating sleeve is rotatably connected within each first sliding groove. A second sliding groove is formed on the rotating sleeve, and a first sliding rod is slidably connected within the second sliding groove. An anti-slip limiting block is fixedly connected to the end of the first sliding rod away from the second sliding groove. A screw hole is formed on the anti-slip limiting block, and a screw rod is rotatably connected within the screw hole. A suction cup is fixedly connected to one end of the screw rod. Through the elastic linkage between the first sliding rod and the anti-slip limiting block, the anti-slip limiting block can automatically adapt to different window frame sizes and form a bidirectional clamping action. Furthermore, through the threaded adjustment mechanism of the screw rod and the suction cup, the suction cup can precisely adjust the suction pressure and form a vacuum seal. This allows for quick and easy installation without tools, thereby improving the adaptability of this device to different window sizes and increasing installation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of sunshade equipment technology, specifically a portable sunshade curtain. Background Technology

[0002] In existing technologies, the installation and fixation of portable blackout curtains typically rely on manually adjustable snap-fit ​​structures or suction cups of a single size, which suffers from cumbersome operation and poor adaptability. For example, traditional blackout curtains often use rigid support rods or bolt locking mechanisms to fix the window frame, requiring tools for length adjustment. This not only results in low installation efficiency but also makes it difficult to adapt to window frames of different widths. Suction cup fixing structures, lacking pressure adjustment capabilities, are prone to problems such as loose adhesion and easy detachment when the glass surface is uneven or has significant thickness differences, leading to insufficient stability of the blackout curtain.

[0003] To address the aforementioned technical deficiencies, this patent proposes an improved solution: through the linkage design of the elastic element and the sliding rod, the anti-slip limiting block automatically adapts to the width of the window frame and forms a two-way clamping during the elastic expansion and contraction process, simplifying the installation process; at the same time, combined with the thread adjustment mechanism of the screw and the suction cup, the suction cup can accurately adjust the adsorption pressure according to the glass thickness and surface condition, enhancing the fixation reliability and environmental adaptability, and ultimately achieving efficient installation and stable fixation of the blackout curtain.
