Abstract

The utility model relates to a modified shutter upper rail supporting seat, its main improvement lie in being equipped with a breach in the top of the through wires hole of supporting seat, make the adjustment line only need stride when the assembly put in the top of through wires hole, pressurize slightly just can lightly get into in the through wires hole to reach convenient quick progressive benefit.

Description

The utility model relates to a support seat arranged on an upper rail of a blind to support an adjustment line. FIG. 1 shows that a conventional support base 3 is installed on the upper rail 21 of the shutter 2 . The support seat 3 shown in Fig. 2 is a plastic integral injection molded part, and support walls 31 are provided on both sides, and a square threading hole 32 is provided at the bottom of the support wall 31 for the adjustment line 22 to pass through. There is a cylinder 33 to facilitate the adjustment line 22 to pass through the support seat, and a U-shaped groove 34 is provided on the upper section of the support wall 31 to provide support for the angle adjustment column 35, as shown in FIG. 3 . However, in actual assembly, this support seat 3 has the following disadvantages:

1. It is quite time-consuming and difficult to pass the adjustment wire 22 through the square threading hole 32, resulting in time-consuming assembly.

2. Since the adjustment wire 22 is not easy to pass through the square threading hole and other needles must be used, not only the quality is not easy to control, but also the needle point is likely to cause injury to the assembly personnel.

In view of the many shortcomings of the threading hole part of the conventional louver upper rail support seat due to poor structural design, the applicant attempted to find a reasonable solution. After active research and design, it was actively improved based on years of work experience, and improved after many experiments. Innovate and propose the utility model.

The purpose of the utility model is to get rid of the disadvantages and shortcomings of the aforementioned conventional blind upper rail support seat due to poor structural design. The main structure of this improvement is to set a gap above the square threading hole, so that the adjustment line only needs to straddle the top of the threading hole, and the adjustment line can be quickly and conveniently dropped into the square threading hole with a little pressure.

An object of the present invention is to provide an improved shutter upper rail support seat with a gap above the threading hole, so that the adjustment line can be easily and conveniently put into the threading hole, so as to achieve the progressive benefit of quick assembly.

The second purpose of this utility model is to provide an improved shutter upper rail support seat with a gap above the threading hole, so that the adjustment line can be quickly inserted without the help of other needles, so that the assembly staff will not be injured. Injured, and to achieve the progressive benefits of safety.

In order to have a further understanding of the content of the utility model and its application value, the utility model is described in detail as follows in conjunction with the accompanying drawings:

Fig. 1 is the general assembly schematic perspective view of the conventional support seat assembled on the shutter upper rail;

Fig. 2 is an assembled perspective view of the conventional support seat of Fig. 1 without an angle adjustment column;

Fig. 3 is an assembled perspective view of the angle adjustment column on the conventional support seat of Fig. 1;

4 to 6 are assembly perspective views of various assembly stages of the improved support seat of the present invention.

The utility model relates to an improved support seat for an upper rail of a shutter. The improved support seat 4 shown in Fig. 4 is a plastic integral injection molded part, a cylinder 41 is arranged in the middle section of the support seat 4, a support wall 42 is formed at both ends of the support seat 4, and a support wall 42 is formed at the lower end of the support wall 42. The symmetrical threading hole 43 is formed with a symmetrical gap 44 above the threading hole 43, the width of which just allows the adjustment line to pass through, so that the adjustment line 22 can be easily and quickly put into the threading hole 43, as shown in Figure 5, in this A symmetrical U-shaped groove 45 communicates with the top of the notch 44 for placing the angle adjustment column 46 , as shown in FIG. 6 .

To sum up, the utility model is provided with the notch 44, so that the adjustment wire can be quickly and conveniently inserted into the threading hole 43, thereby achieving the progressive benefit of saving time and convenience.

Claims (1)

1. An improved support seat for the upper rail of the louver, which is a plastic integral injection molded part. There is a cylinder in the middle of the support seat, and symmetrical support walls are formed at both ends of the support seat, and a U is provided at the upper end of the support wall. U-shaped groove and a threading hole at its lower end, which is characterized in that there is a through gap between the U-shaped groove and the threading hole. Put it on the top of the threading hole, and with a little pressure, the adjustment line can be dropped into the threading hole through this gap, so as to achieve the progressive benefit of convenient assembly.
