Description

A scroll bar screen and its screen positioning device

technical field

The present invention relates to a scroll bar screen, in particular to a scroll bar screen that can be positioned anywhere.

Background technique

At present, a number of doors and windows will be set up in buildings so that outdoor sunlight and air can enter the room through the aforementioned doors and windows, and in order to prevent outdoor mosquitoes and flying dust from entering the room, many doors and windows will be equipped with a screen to stop mosquitoes and Flying dust enters the room, and the use of screens has become one of the must-install devices for doors and windows at present; however, most of the current screens are flat structures, so when the aforementioned flat screens are installed on doors and windows, people often look at them. The line of sight outside the window is blocked; therefore, in order to improve the aforementioned problems, many people use the scroll bar screen to replace the usual flat screen, and use the scroll bar screen scrolling function to make it easier for people not to use it. When installing the screen, it can be rolled up and hidden on one side of the door and window, so as to improve the problem that the flat screen easily blocks people's view of the beautiful scenery outside the window.

As shown in Figure 1 and Figure 2, a conventional scroll bar screen 1 is disclosed, which mainly includes a retracting unit 11, a gauze 12 and a handle 13; wherein the retracting unit 11 has at least one rotating shaft 14, and the two ends of the gauze 12 are fixed on the pull handle 13 and the rotating shaft 14 respectively, so when the gauze 12 is to be folded, the rotating shaft 14 can be rotated so that the gauze 12 can be rolled up on the rotating shaft. on the moving shaft 14, so that the gauze 12 no longer obstructs people’s view of the beautiful scenery outside the window; Expand to achieve the expected benefit of preventing mosquitoes from entering the room.

However, although the above-mentioned commonly used scroll screen can achieve the effects of rolling without blocking the view outside the window and preventing mosquitoes from entering the room, it is found that when the gauze 12 is unfolded, the handle 13 cannot be unfolded with the gauze 12. It can be positioned arbitrarily, but it is inconvenient to use, and after using the conventional scroll bar screen on the gauze 12, it is necessary to add a screen on the door and window (as shown by the imaginary line in Figure 1 and Figure 2). Hook piece 15, after the gauze net 12 is unfolded, the buckle 16 on the handle 13 can be hooked on the hook piece 15 of the door and window, so that the gauze net 12 has no risk of being rolled back, but the aforementioned hook piece 15 and buckle ring Setting, not only increases the cost but also has the trouble of labor-intensive and time-consuming installation.

Contents of the invention

The present invention mainly solves the problem that the pull handle cannot be arbitrarily positioned according to the unfolded position of the gauze in the conventional technology, and also has the problems of high cost and labor-intensive and time-consuming installation in the structure.

In order to solve the problems of the conventional technology, the present invention provides a scroll bar screen, which includes: two side frames arranged at intervals; a rolling mechanism arranged between the two side frames; The gauze that is pulled out and unfolded; one pull handle set at one end of the gauze; two positioning pull wires set on the frames on both sides, and the two positioning pull wires pass around the pull handle, and each of the two positioning pull wires is equipped with a screen positioning device ; Therefore, the tension of the two positioning pull wires is regulated by the screen positioning device, so that the handle can be positioned between the two frames arbitrarily, so that the gauze can be positioned anywhere.

The beneficial effects of the present invention are: the present invention mainly solves the problem that the pull handle cannot be arbitrarily positioned according to the unfolded position of the gauze in the conventional technology, and also has problems such as high cost and labor-intensive installation in the structure.
