Description

Technical Field

[0001] The utility model belongs to the field of curtains, in particular to a cover box and a mounting code of a rolling curtain. Background Art

[0002] The lifting roller blinds include single-layer roller blinds, double-layer soft gauze blinds, Shangri-La blinds, and a combination of single-layer roller blinds and double-layer soft gauze blinds, including a cover box, a 28# or 38# reel tube, a slot for the roller blind head on the reel tube, a head and tail control that rotate on both sides, a lower beam, and a fabric curtain. The cover box includes a rear cover plate, a top cover plate, a front cover plate, and a bottom cover plate. The cover plate has screw positions for fixing the cover seal with screws, and the cover seal with a tongue for installing the head and tail control (the cover seal is plastic, transparent or color-matched; the side code is also used to install the head and tail control, and is made of metal. When using the side code, it is generally necessary to cover the side code with the cover seal), the top cover plate and the bottom cover plate of the cover box are usually provided with slots for decorative edging, and the rear cover plate or the front cover plate of the cover box is provided with a slot for the double-layer roller blind tail. However, the existing side-mounted L-shaped spring telescopic buckle and the top-mounted straight-line spring telescopic buckle are mutually restricted by the two opposite T-slots set on the top cover plate of the cover box. Widening the top cover plate causes the edging decorative slot to be set only next to the T-slot. If the edging decorative slot is set on the top cover plate of the split front cover plate, the entire top cover plate will be too wide and the amount of aluminum profiles used will be increased. The space where curtains are installed is generally small, and it is difficult to install if there is a slight gap of 10 mm. Therefore, there is currently no split front cover plate, and all of them are one-piece rolling curtain boxes; in addition, when installing the rolling curtain box, the installation code is first fixed, and then the T-slot outside the top cover plate buckles the telescopic spring buckle and presses it backward until the inner T-slot falls into the buckle inside the installation code, and the buckle relaxes and rebounds to buckle with each other. A gap must be reserved between the L-shaped side vertical wall and the rear cover plate. The side vertical wall of the installation code does not contact the rear cover plate, resulting in two or more sizes, especially the rear cover plate size can be set arbitrarily. The rear cover plate and top cover plate of the rolling shutter cover box are not common and rarely change in shape, both are right-angled L-shaped, and the front cover plate and bottom cover plate are commonly decorated with various shapes and edging, straight, streamlined, curved, circular arc, straight arc combination, edging and non-edging, widened and narrowed bottom cover plate, plus the existing rolling shutter cover box can only be formed in one piece, it is necessary to prepare rolling shutter cover boxes of various specifications, resulting in increased use of aluminum profile materials and increased costs. In summary, there are three shortcomings of the existing rolling shutter cover box: first, there are two types of spring buckle installation codes, side-mounted L-shaped and top-mounted straight-shaped, and two T-shaped slots on the top and back of the top cover plate, and a single structure of the installation code cannot be used; second, the cover box is formed in one piece, the front cover plate and the bottom cover plate have a variety of decorative shapes, the top cover plate and the rear cover plate are not common and have a single shape, and there is no separation to achieve a base cover corresponding to a variety of front cover plates and bottom cover plates; third, the installation code and the rear cover plate have no hook contact, resulting in different sizes of the rear cover plate, many models and specifications, greatly increasing the cost, and cannot be used in combination.
