Technical Field

[0001] The utility model relates to the technical field of detachable installation structures, in particular to a screen window installation structure. Background Art

[0002] Screens are used to ensure good ventilation while preventing mosquitoes from entering the room. There are two main types of existing screen installations: one is non-detachable and is set on the window frame by a rotating connection; the other is detachable and is installed on the window frame by a buckle and can be removed when not in use. The most common way to install existing detachable screens is to insert the left, right, and top clips of the screen frame into the grooves of the frame, lift it up, and then place the bottom in the grooves of the frame. Finally, the screen frame is locked by the sliding clip at the bottom. The structure is simple and easy to install.

[0003] However, since the screen window frame needs to be lifted up and then slid down during installation, a transition fit needs to be made between the card strip and the card slot, the sealing of the connection is poor, and finally it is only fixed at the bottom. The top may shake in the direction perpendicular to the screen window and produce noise, especially in windy weather, the noise is more obvious, and the poor sealing of the connection will cause sand and gravel to enter the card slot, which is difficult to clean, and will cause wear to the window frame over time, affecting the subsequent installation and disassembly.

[0024] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0025] According to the instruction manual Figure 1-7 It can be seen that when installing the utility model, the screen window frame 3 is first buckled as a whole in the installation interval 27 formed by the frame 1 and the blocking frame 2, and the rubber sealing pad 11 of the screen window frame 3 is as close to the front wall of the blocking frame 2 as possible. At this time, the personnel use tools to make the driving component work. Since the long rod 16 is movable and penetrates the first through hole 17, the moving end of the driving component moves, thereby driving the long rods 16 above and below the first groove cavity 25 to move respectively. The guide ring 14 connected to the other end of the long rod 16, because the guide ring 14 is 4 5 degrees, and the slide bar 6 penetrates the guide opening 15 of the guide ring 14. At the same time, the guide ring 14 is vertically slidably connected with the side wall of the first groove cavity 25 through a sliding member, and the slide bar 6 is horizontally slidably connected with the side wall of the first groove cavity 25 through a sliding member. Therefore, the movement of the long rod 16 can drive the guide ring 14 to move vertically, thereby driving the slide bar 6 to move horizontally. The horizontal movement of the slide bar 6 can drive the push rod 7 and the movable card plate 8 to move horizontally, so that the movable card plate 8 can be clamped between the fixed card plate 4 and the blocking frame 2. Since the movable card plate 8 is set on both sides of the center of the vertical end face of the screen window frame 3, the clamping with the fixed card plate 4 can make the screen window frame 3 and the blocking frame 2 and the fixed card plate 4 more stable, without shaking, and avoid noise. The clamping of the movable card plate 8 and the fixed card plate 4 and the rubber sealing pad 11 increase the sealing of the edge, prevent sand and dust from entering the gap between the screen window frame 3 and the blocking frame 2, reduce wear, and increase the service life.

[0026] The driving assembly includes a gear 19, a pair of racks 18 and a driving rod 21. When working, a person inserts a tool into the second through hole 24 and docks it with the slot 22 on the end face of the driving rod 21. The slot 22 here can be set in a cross shape or a hexagonal groove shape, which is convenient for people to use a corresponding wrench to operate. The driving rod 21 is rotated to drive the gear 19. Since the gear 19 is rotatably connected to the side wall of the first groove cavity 25 through the connecting column 20, and the gear 19 is meshed with the rack 18 vertically slidably connected to the side wall of the first groove cavity 25 through the sliding member, the gear 19 rotates. The kinetic energy can drive the rack 18 to move vertically. A pair of racks 18 are centrally symmetrical with respect to the center position of the gear 19. In order for the rack 18 to be fixedly connected to the long rods 16 on the upper and lower sides of the first groove cavity 25 through the connecting plate 29, the movement of the rack 18 drives the long rod 16 to move. The rotation direction of the gear 19 is different, and the vertical movement direction of the long rod 16 is different, so that the horizontal movement direction of the movable card plate 8 is different. The matching relationship between the gear 19 and the rack 18 is more stable, not easy to be damaged, and the service life is improved. The installation and removal of personnel are also faster. In addition, the second through hole 24 can be buckled with a block 23 flush with the front side wall of the screen window frame 3 to ensure beauty.

[0027] Among them, the edges and corners of the movable clamping plate 8 and the fixed clamping plate 4 are set to be chamfered angles 13. When the screen frame 3 is installed in the installation interval 27, and the movable clamping plate 8 is locked with the fixed clamping plate 4, the existence of the chamfered angle 13 can make the two more convenient to install.

[0028] A protective plate 26 is provided at a position corresponding to the notch of the first slot cavity 25 , and the protective plate 26 is used to prevent dust from entering the first slot cavity 25 and affecting the matching relationship of the internal structure.

[0029] Among them, the front side wall of the screen frame 3 can be flush with the front side wall of the frame 1 to ensure the beauty after installation. A convex edge 12 is provided on the side end face of the screen frame 3. The convex edge 12 can be covered on the fixed card plate 4 and close to the side wall of the frame 1, further increasing the edge sealing while improving the aesthetics.

[0030] The sliding member in the utility model can adopt the existing technology, such as the cooperation between the sliding groove and the sliding block.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
