Abstract: A screen guide frame structure and a screen device having same. The present invention mainly comprises providing a passage on the screen guide frame structure. When a screen is stored or unfolded, the passage can allow one end of a windproof hook to slide therein; moreover, since the other end of the windproof hook is hooked onto a net line of the screen, the screen device cannot be blown away from the outside of a guide frame when there are strong winds.

Abstract: A flat-type ventilation door-window structure includes a frame (1), a first movable sash (2) and a second movable sash (3). The first movable sash (2) and/or the second movable sash (3) can slide up and down in an opening (11) of the frame (1). A first guide device (300) and a second guide device (400) being respectively provided between the first movable sash (2) or the second movable sash (3) and the frame (1). The first guide device (300) and the second guide device (400) can guide the first movable sash (2) or the second movable sash (3) to change the sliding path. The flat-type ventilation door-window structure can block outdoor sound, rain and air, and improve sound insulation, water tightness and air tightness.

Abstract: A wire drawing tightness controller for an easily detachable and foldable screen, comprising: a connecting member, a wire drawing control device, a first connecting unit and a second connecting unit, wherein the connecting member is provided on a window frame, the wire drawing control device is provided with at least a control unit, and the first connecting unit and the second connecting unit are arranged between the connecting member and the wire drawing control device. By means of the arrangement of the first connecting unit and the second connecting unit, the wire drawing control device can be conveniently connected to the connecting member, and can also be easily separated from the connecting member, thereby enhancing the convenience of assembling a foldable screen.

Abstract: A window frame assembly has a built-in foldable screen, having a body, the body having at least a first frame part and a second frame part; the first frame part has at least a first end surface and a second end surface; the second end surface is fixedly connected to the second frame part; the first end surface is provided with a protruded guiding convex part; the guiding convex part is provided with a line receiving groove; and two sides of the line receiving groove are respectively provided with a concave part. The above structure has the benefits of enabling the guiding convex part located on the transverse frame in the foldable screen module to be re-assembled on the structure of the window frame assembly, thus reducing the number of foldable screen module components, and also improving the convenience of assembling the foldable screen module in the window.

Abstract: A chain structure for a screen device comprises a plurality of chaining unit members (10). Each chaining unit member comprises a bridging portion (11), and comprises a first pivotal connection portion (12) and a second pivotal connection portion (13) that are disposed on two opposite sides of the bridging portion. The chaining unit members are connected by means of the first pivotal connection portions and the second pivotal connection portions, so as to form a chain structure (1). By means of the structure arrangement, the plurality of chaining unit members is serially connected; in this way, when the chain structure slides in the screen device, by means of the swing and pivotal movement of the bridging portions, the problems in the prior art that a member is likely to deform, the slide is not smooth and there is noise can be avoided.

Abstract: A method for capturing a size of an installation space for a door/window using remote image includes providing an installation space for a door/window having an edge, disposing a size-calibrating member at one side of the edge of the installation space for the door/window, using an image capturing device to acquire an image that contains with the installation space for the door/window and the size-calibrating member, transmitting mentioned image to an image measurement system, using the image measurement system to analyze the image and determine an image ratio between the installation space for the door/window and the size-calibrating member, and a practical size of the installation space can be figured out based on mentioned image ratio and a practical size of the size-calibrating member.
