All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention relates to a ladder belt fixer for controlling the retraction and the expansion of a curtain, which comprises:

the fixing seat body 4 and the sleeve 1;

the sleeve 1 is a hollow cylindrical body with openings at two ends, two groups of protrusion groups 2 are circumferentially arranged on the outer wall, the two groups of protrusion groups 2 are arranged in a staggered mode, a ladder belt is wound between the two groups of protrusion groups 2, and each protrusion group 2 comprises at least two protrusions;

the fixing seat body 4 is used for placing the sleeve 1, and the sleeve 1 can rotate relative to the fixing seat body 4.

The following description will be made in detail with reference to the holder body 4 and the sleeve 1.

Fixing base body 4

As mentioned above, the holder body 4 is used for placing the sleeve 1, and the sleeve 1 is rotatable relative to the holder body 4.

Specifically, as shown in fig. 2, the fixing seat body 4 includes a bottom plate 41, a first feature 42 and a second feature 43 located at two ends of the bottom plate 41; the ladder strap passes through the bottom plate 41; the two ends of the sleeve 1 are respectively arranged on the first feature piece 42 and the second feature piece 43, and the protrusion group 2 is positioned between the first feature piece 42 and the second feature piece 43.

As shown in the figure, the first feature 42 and the second feature 43 may have the same structure, the first feature 42 and the second feature 43 are symmetrically disposed at two ends of the bottom plate 41, and a non-closed hollow cavity is enclosed between the two features, and the two sets of protrusion sets 2 are located in the non-closed hollow cavity. The first feature 42 and the second feature 43 may be U-shaped, and the middle of the U-shaped structure is provided with a groove 44, and the two grooves 44 are used for placing the sleeve 1.

When the first feature 42 and the second feature 43 enclose an unsealed hollow cavity, a top cover can be disposed above the holder body 4, and the top cover is used for covering the protrusion set 2.

In order to facilitate the arrangement of the top cover 5 without affecting the normal operation of the protrusion set 2, as shown in fig. 3, the top cover 5 may be an arch 51, and the arch 51 is arched in a direction away from the protrusion set 2. Specifically, the arch structure 51 may be a semicircular structure, and the four corners of the semicircular structure are respectively provided with an outward extending L-shaped rib 52, and the L-shaped rib 52 may hook the outer wall of the U-shaped structure. Specifically, the arch structure includes four ribs 52 symmetrically disposed, and each two ribs 52 respectively hook the first feature 42 or the second feature 43.

(II) Sleeve 1

As described above, the two ends of the sleeve 1 can be disposed on the first feature 42 and the second feature 43, and can rotate relative to the holder body 4.

The sleeve 1 may be a hollow cylinder with both ends open as shown in the drawing, and the shape thereof is not particularly limited.

As shown in figure 1, two groups of protruding groups 2 are arranged on the outer wall of the sleeve 1 in the circumferential direction, and the two groups of protruding groups 2 are arranged in a staggered mode. The offset arrangement is understood to mean that in two sets of projections 2, the extension line of the position of the projections of one projection set 2 is located between two projections of the other projection set 2. As shown, each of the protrusion sets 2 includes at least two protrusions arranged at intervals, preferably at equal intervals.

A ladder belt is wound between the two groups of convex groups 2. In the rotating process of the sleeve 1, the two groups of the convex groups 2 drive the ladder belt to move up and down. In particular, the ladder tape comprises two ladder tapes (respectively shown as a first ladder tape 31 and a second ladder tape 33) and an intermediate tape 32 connecting the two ladder tapes, each intermediate tape 32 being used for placing a vane 6 between. The first ladder strap 31 moves up or down, and the second ladder strap 33 necessarily moves in the opposite direction, thereby achieving the retraction or deployment of the blades 6. As shown in fig. 1(b), the protrusions of the protrusion sets may have a circular arc shape on a surface adjacent to the protrusions of the other protrusion set, and thus, the surfaces of the protrusions of the two protrusion sets adjacent to each other are both arc-shaped, the ladder tape, such as the first ladder tape 31 or the second ladder tape 33, is sandwiched between the protrusions of the staggered circular arc shapes, and the first ladder tape 31 or the second ladder tape 33 has a corrugated shape (also can be understood as an S-shape), so as to prevent the ladder tape from slipping during the up-and-down movement.

The invention also provides a curtain, which comprises the ladder belt fixer for controlling the dimming of the curtain, namely the retraction or the expansion of the blades. The ladder belt fixer is arranged in the guide rail 7, the ladder belt bypasses the ladder belt fixer, a blade is arranged between every two middle belts 32, the blade is driven to be in the unfolding state shown in figure 5 or the folding state shown in figure 6 in the moving process of the first ladder belt 31 and the second ladder belt 33, and therefore the dimming effect of the curtain is achieved. As shown in fig. 4, 5 and 6, the window covering further includes a handle 8 for driving the sleeve 1 to rotate and a shaft 9, wherein the shaft 9 penetrates through the sleeve 1 and is connected with the handle 8.

The beneficial effect of adopting above-mentioned technical scheme is:

because the ladder belt fixer for controlling the curtain to adjust the light, namely retracting or unfolding the blades, comprises the sleeve 1 and the fixing seat body 4, the sleeve 1 is used for penetrating through the rotating shaft, when the rotating handle 8 is rotated to drive the rotating shaft 9 to rotate, the sleeve 1 for penetrating through the rotating shaft 9 rotates to drive the two protrusion groups 2 to rotate, the ladder belt which bypasses between the two protrusion groups 2 rotates anticlockwise or clockwise, the blades 6 are controlled to retract or unfold, and the light adjusting effect of the curtain is realized.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
