Abstract

The utility model relates to the technical field of household articles, in particular to an improved structure of a shutter blade of a shutter hung on an indoor window for blocking the view of the inside and outside of a compartment. The improved structure of the shutter curtain blade is composed of an inner core and an outer skin, wherein the inner core in a strip sheet shape is sandwiched by a whole outer skin, and the inner core is contained in the outer skin through a sewing line along the long edge and sewing lines at the two ends; the short side of the inner core is arc-shaped, and the inner core and the outer skin are in smooth arc butt joint in the wrapping clamp; the inner core is made of aluminum materials, wood chips or plastic sheets; the utility model adopts the whole piece of outer skin to clamp the inner core, solves the problem of sewing and positioning existing when clamping the inner core by two pieces of outer skin, omits the processing procedure of a sewing line, and does not need any extra change on products and production technology.

Description

Improved structure of shutter blade

Technical Field

The utility model relates to the technical field of household articles, in particular to an improved structure of a shutter curtain blade hung on an indoor window and used for blocking the view field inside and outside a compartment.

Background

In indoor work and life, people generally hang curtains on windows of rooms to cut off the sight between the indoor and outdoor for the privacy of work and life. The shutter curtain can be folded in hanging and can be adjusted between full opening or closing by adjusting the rotation angle of the blades, so the shutter curtain is favored by consumers. The shape and composition of the shutter slats also become a necessary reference factor for consumers to purchase the shutter. Therefore, manufacturers are required to consider not only the low price and the good quality of products and durability, but also the processing aesthetics of each shutter blade to attract more customers to use when processing and manufacturing the shutter.

In the chinese patent CN 208122729U, a structure as shown in fig. 1 and 2 is proposed, "the curtain blade is formed by a long cylindrical sleeve 1 and a sheet 2, the sheet 2 has a predetermined length and a predetermined cross-sectional shape, the sheet 2 is inserted into the long cylindrical sleeve 1 and positioned, the long cylindrical sleeve 1 is formed by connecting two upper and lower fabrics or leather materials through sewing and lockstitching, the left and right sewing and lockstitching of the long cylindrical sleeve 1 clamps the side edge of the sheet 2, and the long cylindrical sleeve 1 is tensioned under the support of the sheet 2, so that the outer surface of the long cylindrical sleeve 1 presents good visual effect and texture. However, when the product is processed according to the processing technology, left and right sewing lines 3 of two pieces of cloth are not easy to align, the processing difficulty is high, and the appearance is not attractive after the processing and forming;

in addition, in the chinese patent CN 201635630U, a structure as shown in fig. 3 is proposed, "the bottom surface of the sleeve piece 3 is adhered to the inner core 1, the middle part of the bottom surface of the sleeve piece 4 is adhered to the inner core, and two sides are adhered to the sleeve piece 3," although the stitching of two sides is eliminated, the adhesion of the bottom surface of the sleeve piece 4 to the inner core 1 in the middle is still an difficult processing problem that is not easy to solve.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide an improved structure of a simple and convenient-to-process shutter curtain blade.

The utility model adopts the following technical scheme: the improved structure of the shutter curtain blade is composed of an inner core and an outer skin, wherein the inner core in a strip sheet shape is sandwiched by a whole outer skin, and the inner core is contained in the outer skin through a sewing line along the long edge and sewing lines at the two ends;

the short side of the inner core is arc-shaped, and the inner core and the outer skin are in smooth arc butt joint in the wrapping clamp;

the inner core is made of aluminum materials, wood chips or plastic sheets;

the outer skin can also be left on the opposite side of the seam line along the long side, and the seam line can be symmetrically added.

The utility model adopts the whole piece of outer skin to clamp the inner core, solves the problem of sewing and positioning existing when clamping the inner core by two pieces of outer skin, omits the processing procedure of a sewing line, and does not need any extra change on products and production technology.

FIG. 1 is a state of the art;

FIG. 2 is a cross-sectional view A-A of FIG. 1;

FIG. 3 is another prior art cross-sectional view;

FIG. 4 is a perspective view of the present utility model;

FIG. 5 is a B-B cross-sectional view of FIG. 4.

Detailed Description

3-4, the improved structure of the shutter curtain blade is composed of an inner core 1 and an outer skin 2, wherein the inner core 1 in a strip shape is wrapped by the whole outer skin 2, and the inner core 1 is contained in the whole outer skin 2 through a sewing line 3 along the long side and sewing lines 3 at two ends;

the short side 11 of the inner core 1 is arc-shaped, and the two short sides are in smooth arc butt joint in the wrapping and clamping with the outer skin 2;

the inner core 1 is made of aluminum materials, wood chips or plastic sheets;

the outer skin 2 may be left on the opposite side of the seam line 3 along the long side, and the seam line 3 may be symmetrically added.

When the utility model is processed and produced, the strip-shaped flaky inner core 1 is wrapped in the outer skin 2 with the length slightly longer than that of the inner core 1, and the operator can wrap the strip-shaped flaky inner core 1 in the outer skin 2 by sewing the sewing line 3 and sewing two short sides along one side of the long side; the circular arc shape of the short side 11 of the inner core 1 can enable each blade to present smooth lines, and the aesthetic feeling of the product is improved.

In order to satisfy the antique feeling of people, the outer skin 2 may be left on the opposite side of the seam line 3 along the long side, and the seam line 3 may be symmetrically added to restore the shape of the previous product.

Claims
