Description

Technical Field

[0001] This invention relates to the field of windproof roller shutters, and more specifically to an adaptive windproof roller shutter. Background Technology

[0002] A windproof roller blind is a system that can be used on both indoor and outdoor facades. It consists of a roller blind box installed at the top of the window for rolling up the blind fabric, and a bottom track located at the bottom of the blind. The bottom track serves partly as a counterweight for the blind fabric. Additionally, to reduce the degree of shaking of the blind fabric when blown by the wind, windproof roller blinds come in two types. One type has guide rails installed on the left and right sides of the window. When the blind is opened or rolled up, the left and right sides of the blind slide within the guide rails, guiding the blind fabric. The other type has traction ropes installed at both ends of the roller blind box. The traction ropes extend downwards and are secured by traction devices. End caps are installed at both ends of the bottom track, and the traction ropes are inserted into the end caps to limit the movement of the bottom track.

[0003] Different types of windproof roller blinds will affect the selection of roller blind boxes. Specifically, the end caps at both ends of the roller blind box need to be adjusted according to the guide rail or traction rope. Existing end caps cannot be adapted to different types of windproof roller blinds at the same time, which increases the difficulty of stocking. In addition, in some scenarios, the installation position of the guide rail is not easy to move, and the vertical width of the guide rail may be inconsistent. Since the width of the curtain is fixed, the curtain may be too loose or too tight in the width direction, resulting in the curtain not running smoothly after installation. This needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive windproof roller shutter that can adapt to different environments to address the above problems.

[0005] To achieve the above objectives, the present invention discloses an adaptive windproof roller shutter, including an end cap, the structural features of which are: a pin seat is provided at the lower part of the end cap, a fixing pin that can be cut off and removed is provided on the lower side of the pin seat, the fixing pin extends downward, a guide rail cavity is provided in the guide rail, and the fixing pin is inserted into the guide rail cavity.

[0006] With the above structure, the lower part of the end cap is provided with a pin seat, and the lower part of the pin seat is provided with a fixing pin. For guide rails that the fixing pin can be matched, the fixing pin can be directly inserted into the guide rail cavity to make the two fit together. For some special profile guide rails, the fixing pin cannot be inserted into the guide rail cavity to match it. The fixing pin can be cut off by cutting it off, so that the roller shutter box can still be used with the guide rail. For windproof roller shutters that use traction ropes, the fixing pin is also cut off by cutting it off. Then, the traction rope is installed by using the positioning sleeve and traction rope fasteners. The end cap of this structure can match various styles of guide rails and traction ropes, thereby improving the compatibility of the roller shutter box and reducing the pressure of inventory.

[0007] To facilitate the insertion of the retaining pin into the guide rail cavity, the lower part of the retaining pin is wedge-shaped.

[0008] In order to enable the end cap to match the windproof roller shutter that uses a traction rope, the lower part of the end cap is provided with a sleeve, and a positioning sleeve for the traction rope to pass through is installed on the sleeve.
