Description

Technical Field

[0001] The utility model relates to the technical field of door and window components, in particular to a screen window hinge which can be quickly disassembled and assembled and is used for an inwardly opened window. Background Art

[0002] Screens are a must-have for window products, especially for low-rise buildings, villas, large courtyards, etc., where mosquitoes can easily fly into the room through the windows, so screens are even more necessary. For inward-opening window products, screens have evolved from the original external hanging type to today's truly integrated window screen type, which has been integrated with the window. Screens have evolved from simply blocking mosquitoes in the beginning to today's ability to block mosquitoes and play an indispensable part in structural overlap sealing. The biggest disadvantage of screens is that dust will hang on the screen over time, affecting the permeability, both the ventilation performance and the light transmission performance, so they must be disassembled and cleaned frequently. At the same time, various after-sales problems will arise after the screens have been used for a long time, and they often need to be disassembled for repair or even replacement. However, integrated screen windows can be opened like window sashes. The screen windows rotate to open and close under the action of hinges for easy disassembly and assembly. Traditional screen window hinges are screen window sash hinges and screen window frame hinges connected in series through pins. Since the frame sash hinges must be aligned before the pins can be inserted, this process is more difficult, which makes the installation of the screen window frame and sash more difficult. Due to the small space available, disassembly is also difficult, especially when the screen window sash is high or the screen window is in a high position, such as in the kitchen. Replacing the screen window requires personnel to climb up to the upper hinge pin position, which is very troublesome to replace. At the same time, there is a possibility that the pin will fall outdoors, creating a safety hazard. Utility Model Content

[0037] In a further embodiment of the present invention, Figure 2 It is a side cross-sectional view of a frameless window screen integrated screen window hinge. The screen window sash 3 and the screen window frame 4 are connected through the screen window hinge to form a complete screen window system. The screen window hinge is made of new nickel alloy, which is simple to manufacture and has good wear resistance. It is divided into two parts, the sash hinge 1 and the frame hinge shaft seat 2. The sash hinge 1 is installed on the sash side and fixed to the sash C groove of the screen window sash 3 through the top screw 5. The hinge has a hinge outer edge 11 symmetrically opened above and below. The hinge outer edge 11 is a cylindrical blind hole, which can be used for both left-opening and right-opening sashes, reducing the types of material inventory. A frame hinge shaft seat 2 is installed in the C groove on the screen frame 4 and fixed by a top screw 5. The frame hinge shaft seat 2 has hinge shafts 21 symmetrically at both ends. The hinge shaft 21 is a cylindrical shaft pin. The cylindrical blind hole of the fan hinge 1 and the cylindrical shaft pin of the frame hinge shaft seat 2 form a gap rotation friction fit.

[0039] In a further embodiment of the utility model, when disassembling, it is only necessary to open the screen window sash 3 and lift the screen window sash 3 upwards, which is very convenient to save manpower and material resources, and there is no need to climb high, and the possibility of the pin shaft falling is also reduced.

[0040] In a further embodiment of the utility model, one screen window can be equipped with more than two screen window hinges according to different sash heights, so as to ensure the usability of the screen window sash 3.

[0041] In a further embodiment of the utility model, the screen window hinge is symmetrically designed and can be used for opening both left and right, thereby reducing material specifications; disassembly and installation are very convenient, thereby improving installation efficiency, and the disassembly and assembly of the screen window sash 3 can be quickly completed without the aid of external auxiliary equipment; the screen window hinge cooperates with the C-groove of the screen window frame 4 and is fixed by a top screw 5, without the need to drive screws into the frame sash or to lead screw holes, and the position can be arbitrarily changed without affecting the aesthetics.

[0042] In a further embodiment of the utility model, the fan hinge 1 is installed on the screen window 3, and the frame hinge shaft seat 2 is installed on the screen window frame 4. The fan hinge 1 is symmetrically arranged at the top and bottom, and the frame hinge shaft seat 2 is symmetrically arranged at the top and bottom. A hinge shaft 21 of the frame hinge shaft seat 2 is rotatably installed in a blind hole on one side of the hinge outer edge 11, so that the frame hinge shaft seat 2 can be located below the fan hinge 1 regardless of whether the screen window 3 is opened to the left or the right, and the fan hinge 1 and the screen window 3 are supported by the frame hinge shaft seat 2.

[0043] In a further embodiment of the utility model, the annular guide wall 22 is an inwardly concave arc surface, and a mounting seat is provided in the middle of the annular guide wall 22. The upper and lower side surfaces of the mounting seat are respectively connected to a hinge shaft 21. The upper end surface of the hinge shaft 21 located on the upper side surface is lower than the upper end surface of the annular guide wall 22, and the lower end surface of the hinge shaft 21 located on the lower side surface is higher than the lower end surface of the annular guide wall 22. The annular guide wall 22 and the hinge shaft 21 are coaxially arranged, so that during the assembly process of the sash hinge 1 and the frame hinge shaft seat 2, the annular guide wall 22 is higher than the size of the hinge shaft 21, and the outer edge 11 of the hinge will first be close to and fit on the annular guide wall 22 of the frame hinge shaft seat 2, aligning the relative positions of the outer edge 11 of the hinge and the hinge shaft 21, and then the screen window sash 3 is pulled downward, so that the blind hole of the hinge outer edge 11 of the sash hinge 1 is matched with the hinge shaft 21 of the frame hinge shaft seat 2, and the installation is very convenient.

[0044] In a further embodiment of the utility model, the sash hinge 1 is fixedly mounted on the screen window sash 3 by means of a top screw 5, and the frame hinge shaft seat 2 is fixedly mounted on the screen window frame 4 by means of a top screw 5. When disassembling, it is only necessary to first open the screen window sash 3 and lift the screen window sash 3 upwards, which is very convenient and saves manpower and material resources, and there is no need to climb high, no need for a pin shaft connection, and the possibility of the pin shaft falling is also reduced.
