Improved external sunshade roller shutter top housing

Abstract

The utility model discloses an improved external sunshade roller shutter top housing which comprises a rear housing and a front panel which are connected through a heat insulation strip. A sound insulation and heat preservation plate inserting groove is formed in the rear shell, and a sound insulation and heat preservation plate is arranged in the sound insulation and heat preservation plate inserting groove. According to the scheme, the sound insulation and heat preservation performance is remarkably improved by additionally arranging the sound insulation and heat preservation plates and the heat insulation strips and adopting a reasonable splicing structure. And the L-shaped design of the top cover plate and the rear shell top cover reserves a gluing position, so that glue does not need to cover the front and rear overhaul plates during gluing, and later maintenance and overhaul are facilitated. In addition, the clamping grooves of the front overhaul plate butt joint buckle and the top cover plate butt joint buckle are designed to be U-shaped, so that stable connection is ensured, and the front cover plate is not prone to falling off and disengaging even if strong wind exists outside.

Description

Technical Field

[0001] The utility model relates to a structure of an external sunshade roller blind, in particular to an improved top cover shell of the external sunshade roller blind. Background Art

[0002] Existing external sunshade roller blinds are usually fixed on the top of the window frame to block sunlight and provide privacy. However, the top cover of conventional external sunshade roller blinds is usually thin and lacks a special sound insulation and heat insulation structure, resulting in a significant reduction in the sound insulation and heat insulation performance of the windows installed with such sunshade roller blinds.

[0003] In addition, in the conventional design of the outer sunshade roller blind housing, the rear cover located indoors covers the entire housing. In order to ensure the sealing effect, it is usually necessary to apply glue to the top gap during installation. However, this design brings inconvenience during maintenance and repair: first, the glass glue needs to be removed before construction; second, after the repair is completed, it needs to be re-glued, which is both costly and time-consuming.

[0004] Therefore, there is an urgent need for an improved external sunshade roller shutter cover that can significantly improve the sound insulation and thermal insulation performance of the window while effectively shading, and simplify the maintenance and repair process, reducing the related time and cost. Utility Model Content

[0005] The purpose of the utility model is to provide an improved top cover shell of an external sunshade roller blind, which significantly improves the sound insulation and heat preservation performance of the external sunshade roller blind by adding sound insulation panels and heat insulation strips in the cover shell and designing a reasonable splicing structure.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An improved top cover shell of an external sunshade roller blind, characterized in that it comprises: a rear shell body with a U-shaped longitudinal section and a front panel with an L-shaped longitudinal section, the top edges of the two being connected by a heat insulation strip; a sound insulation and heat preservation board slot is provided in the rear shell body, and a sound insulation and heat preservation board is provided in the sound insulation and heat preservation board slot.

[0008] A further preferred technical solution is that the front panel includes a horizontally arranged top cover plate and a vertically arranged front inspection plate; the longitudinal section of the top cover plate is L-shaped, and its horizontal end is provided with a first insulation strip docking groove, and its vertical end is provided with a front inspection plate docking buckle; the top end of the front inspection plate is provided with a top cover plate docking buckle, and the bottom end is provided with a first window docking interface connected to the window body; the front inspection plate docking buckle and the top cover plate docking buckle are mutually buckled and connected.

[0009] A further preferred technical solution is that the slot of the front inspection panel docking buckle is U-shaped and the opening is upward; the slot of the top cover panel docking buckle is U-shaped and the opening is downward. This design can ensure that the two are firmly connected, and the front cover plate will not fall off easily even if there is a strong wind outside.

[0010] A further preferred technical solution is that the rear shell body includes a rear shell body top cover, a rear inspection panel and a rear shell body bottom cover; the rear shell body top cover is L-shaped, and a second thermal insulation strip docking groove is provided at its horizontal end; a rear inspection panel docking groove is provided at its vertical end, and an upper notch on the sound insulation board is provided on the inner wall of the rear shell body top cover; a top cover plug matching the rear inspection panel docking groove is provided at the top of the rear inspection panel, and a bottom cover plug perpendicular to its board surface is provided at the bottom end; a rear inspection panel slot matching the bottom cover plug is provided at one end of the rear shell body bottom cover, and a second window docking interface connected to the window profile is reserved at the other end; a lower notch on the sound insulation board is provided on the inner wall of the rear shell body bottom cover.

[0011] In a further preferred technical solution, the sound insulation and heat preservation board is made of polyurethane foam or rock wool material. These two materials have excellent performance in sound insulation, heat preservation, fire prevention, etc., and can significantly improve the performance of the top cover of the external sunshade roller blind.

[0012] In a further preferred technical solution, the heat insulation strip is made of glass fiber reinforced polyamide material. This material has excellent heat insulation performance and high mechanical strength, which can ensure the stable connection between the front panel and the top edge of the rear shell, and effectively block heat conduction, thereby improving the overall heat insulation effect.

[0013] The beneficial effects of the utility model are:

[0014] 1. Excellent sound insulation performance: By adding sound insulation panels inside the cover, external noise can be effectively blocked to improve the quiet environment indoors.

[0015] 2. Excellent thermal insulation effect: The combination of thermal insulation strips and sound insulation panels significantly improves the thermal insulation performance of windows and is suitable for buildings in cold areas.

[0016] 3. Strong structural stability: The docking buckles of the front inspection panel and the top cover are designed as U-shaped slots to ensure a stable connection. Even in strong winds, the front cover will not fall off easily.

[0017] 4. Easy maintenance and overhaul: The L-shaped design of the top cover and the top cover of the rear shell reserves a position for gluing, so that the inspection panel can be opened without scraping off the glass glue during later maintenance and overhaul. There is no need to glue again after the overhaul, saving time and cost.

[0018] 5. Good splicing firmness: Each component is connected by slots, buckles and screws to ensure the firmness and sealing of the overall structure and enhance the wind resistance of the cover.

[0019] 6. Material selection: Sound insulation and heat preservation boards made of polyurethane foam or rock wool have excellent sound insulation, heat preservation and fire resistance, which significantly improve the overall performance of the housing. The heat insulation strip made of glass fiber reinforced polyamide can ensure the stable connection between the front panel and the top edge of the rear shell, while effectively blocking heat conduction and improving the overall heat insulation effect.

[0020] 7. High design flexibility: The design of each component is easy to produce and install, and can be flexibly adjusted according to actual needs, suitable for various window types and architectural styles.

[0021] Through these technical advantages, the top cover of the external sunshade roller blind of the utility model can improve the sound insulation and thermal insulation performance of the window while effectively shading, enhance the stability of the structure, facilitate maintenance and repair, and has significant practical value.
