Description

screen device

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

According to the home or office, in order to achieve the purpose of shading, shielding or preventing outdoor mosquitoes and flying dust from entering the room, most buildings will install a screen device on its opening, and the current screen device is roughly divided into There are two types of flat screen and hidden screen. However, since the current hidden screen has multiple functions such as shielding and storage at the same time, the current hidden screen has gradually replaced the flat screen device.

The most common hidden screen at present is mainly to wind up the gauze through a reel, and then pull out the gauze by pulling the movable rod in the screen structure, so as to achieve the functions of shading and shielding. The hidden screen will add a number of pull wires and pull wire control devices in the structure, in which the pull wire passes through the movable rod, and the pull wire control device is used to adjust the tightness of the pull wire, so that the movable rod in the hidden screen can be adjusted. And gauze can have the function of positioning anywhere, but although the conventional hidden screen can achieve the expected function, there are still the following problems in use:

1. The pull-wire control devices in the conventional hidden screen are installed on the inside of the frame, such as Taiwan Invention Patent No. I684422, but the inner side of the frame is often the path for the screen and the movable frame to open or store, so the conventional hidden screen is used. When a tool is inserted into the cable adjusting device to adjust the cable, it is often hindered by the screen or the movable frame, which leads to inconvenience of adjustment, and the problem is more obvious when the screen is larger.

2. When assembling the frame material in the conventional hidden screen, additional pneumatic or electric tools are often required to assemble the conventional hidden screen. However, when working in an environment without electricity or inflatable equipment However, the progress of the project is often blocked due to the exhaustion of tool power or insufficient air pressure.

3. The reel barrel in the conventional hidden screen is usually assembled on the outer frame by means of screws. Therefore, when the conventional hidden screen is repaired or cleaned, and the reel barrel needs to be removed, it must be re-installed. The reel barrel can be removed only after the tool unscrews the screw-fastening element, which not only wastes labor costs, but also easily causes inconvenience in disassembly.

Fourth, when the conventional hidden screen is used on the opening of a large-width building, a reel with a large retracting force is often configured to retract the large-area screen and movable frame. However, this structural configuration often leads to The unfolded screen is displaced by the large retracting force of the reel, which makes conventional hidden screens prone to problems such as light leakage, reduced shading, or inability to prevent outdoor mosquitoes and flying dust from entering the room.

The main purpose of the present invention is to set the mechanism for adjusting the pulling wire on the outside of the reel barrel, so when the tension of the pulling wire needs to be adjusted, it is only necessary to use a tool to operate on the outside of the reel barrel, and there is no resistance of any component in between. Therefore, in addition to preventing the inconvenient adjustment of the conventional technology, the adjustment process is not limited by the width of the screen.

Another main purpose of the present invention is to provide a convex rib and its corresponding embedding groove on the assembling structure of the frame material, so that the assembly of the frame material can be fast and convenient through the mutual assembly of the convex rib and the embedding groove. In addition to the benefits, it can also be quickly clamped and completed without the cooperation of tools, thereby eliminating the delay or obstruction of the project progress when the conventional technology operates in an environment without electricity or inflatable equipment.

Another main purpose of the present invention is to add a mounting piece between the cylinder body and the outer frame, and to combine the hooking part on the mounting piece with the hooking part of the cylinder body, so that the cylinder body can be installed without any tools. Disassembly and assembly, thereby increasing the convenience of disassembly and assembly.

Another main purpose of the present invention is to provide a positioning rod in the movable frame, and the end of the positioning rod is abutted against the adjacent frame material, so that the unfolded screen and the movable frame can be pulled without being pulled under the large winding force of the reel. Therefore, it can improve the problem of light leakage, reduce shading or cannot prevent outdoor mosquitoes and flying dust from entering the room.
