Technical Field

[0001] This utility model relates to the technical field of screen windows, and in particular to a retractable screen window. Background Technology

[0002] Window screens are a common household item, offering multiple functions such as mosquito prevention, dust prevention, and ventilation. With the development of window screens, a retractable type has emerged. When the hook is opened, the screen automatically retracts into the frame. Our company has developed a new locking structure based on existing retractable window screens. Referring to a hidden window screen with a hook-lock device (publication number: CN220059400U), a fixed hook is installed on the window frame, and a movable hook is installed on the window sash. The fixed and movable hooks secure the screen, and the movable hook releases the tension under the reaction of a spring. The hook is tightly pressed against the fixed hook lock, thus achieving the function of closing the screen window; however, such a locking structure is very complicated and inconvenient to manufacture and install. At the same time, existing window types may not be equipped with screen windows, and some screen windows are added later. Moreover, the screen window itself needs to be disassembled, cleaned and maintained regularly. Therefore, adding a screen window generally requires fixing it to the window through an installation frame, and then installing and fixing the screen window inside the installation frame. The profile surface of the installation frame and the profile surface of the screen window frame meet, making the screen window look particularly bulky. In addition, a gap will be formed between the installation frame and the screen window frame, making the existing added screen window unsightly. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As shown in the attached drawings, this utility model discloses a retractable screen window, comprising an additional frame 1, a screen frame 2, and a screen sash 3. The additional frame 1 is located on the rear side inside the screen frame 2, and the screen sash 3 is located on the front side inside the screen frame 2. The screen sash 3 includes a retractable mechanism 31, a sash profile 32, and a screen mesh 33. The screen frame 2 includes a first vertical profile 21, a second vertical profile 22, and two horizontal profiles 23. The retractable mechanism 31 is located inside the first vertical profile 21. Both horizontal profiles 23 have inwardly protruding track portions. The second vertical profile 22 has inwardly protruding connecting portions. A hook lock 4 is provided on the side of the sash profile 32 away from the screen mesh 33. The hook lock 4 can be directly implemented using existing structures. The connecting portion has a slot 200 corresponding to the hook lock 4.

[0021] This utility model discloses a retractable screen window. By opening a slot 200 on the connecting part, it replaces the original fixed lock seat and hook lock 4, saving production costs and time, and making installation easier. Moreover, by arranging the screen sash 3 and the mounting frame 1 in a front-to-back arrangement within the screen frame 2, it replaces the existing structure where the screen frame 2 is set within the mounting frame 1 and the screen sash 3 is set within the screen frame 2. In the existing structure, when the screen window is closed, the single-sided profile surface is equivalent to the combined single-sided profile surface of the mounting frame 1, the screen frame 2, and the screen sash 3. Now, by using the screen sash 3 and the mounting frame 1 to overlap in the screen frame 2, the profile of the mounting frame 1 is hidden, thereby reducing the overall width of the screen window profile surface. At the same time, the connecting part and the track part of the protruding part of the screen frame 2 cover the gap between the screen frame 2 and the mounting frame 1, making it more concise and beautiful from the front.

[0022] In this embodiment, the hook lock 4 includes a base 41, a movable hook 42, and a spring 43. The base 41 has a groove 410 on the side facing the slot 200. A first positioning post 401 is provided at both ends of the groove 410. The movable hook 42 includes a body 421. One end of the body 421 has an arrow 422 for hooking onto the slot 200, and a second positioning post 424 is provided on one side of the other end. The spring 43 is disposed within the groove 410, and its two ends are respectively fitted onto the first positioning post 401 and the second positioning post 424, meaning the spring 43 is in a movable position. At the top of hook 42, spring 43 is used to hold the bottom movable hook 42, so that the movable hook 42 hooks the bottom of slot 200. Alternatively, spring 43 can be set at the bottom of movable hook 42 to hold the movable hook 42 upward. The first positioning post 401 and the second positioning post 424 are mainly to prevent spring 43 from disengaging from groove 410. The side of base 41 away from groove 410 has an opening that connects to groove 410. The side of main body 421 away from the second positioning post 424 has a positioning groove. The positioning groove is used to position and cooperate with the first positioning post 401, that is, the first positioning post 401 can extend and retract in the positioning groove.

[0023] In this embodiment, the arrow 422 is an isosceles trapezoid with two symmetrically arranged inclined surfaces. The two inclined surfaces are used to abut against the opening of the slot 200. The arrow 422 is used to hook onto the opening of the slot 200. When the yarn fan 3 is closed, the inclined surface on the movable hook 42 will abut against the opening of the slot 200. As the yarn fan 3 continues to move, the movable hook 42 moves upward along the inclined surface, thereby compressing the spring 43. After the arrow 422 of the movable hook 42 enters the slot 200, the spring 43 rebounds and drives the movable hook 42 to push downward again, so that the arrow 422 hooks onto the opening of the slot 200.

[0024] In this embodiment, two baffles 221 are provided at intervals on the faces of the first vertical profile 21 and the connecting part. The straight distance between the two baffles 221 corresponds to the thickness of the fan profile 32, so that when the fan 3 is open, the fan profile 32 is between the two baffles 221 of the first vertical profile 21, and when closed, the fan profile 32 is between the two baffles 221 of the second vertical profile 22, which helps the fan profile 32 return to its original position.

[0025] In this embodiment, the connecting part, the track part, and the baffle 221 located on the first vertical profile 21 are all provided on the front side of the added frame 1. The connecting part, the track part, and the baffle 221 are used to block the gap between the screen frame 2 and the added frame 1, so that even if the screen sash 3 is opened, people will not be able to see the existence of the gap, thus improving the overall aesthetics of the screen window.

[0026] In this embodiment, the mounting frame 1 is provided with a pin 100. The two horizontal profiles 23 are provided with abutting parts for abutting against the pin 100 on their facing sides. The pin 100 can be a regular pin or a detachable pin shaft. Preferably, at least four pins 100 are provided, and they are arranged vertically and vertically inside the mounting frame 1. The pins 100 are telescopic and protrude outside the mounting frame 1. During installation, the mounting frame 1 is first fixed to the wall or window, and then the screen frame 2 is placed over the mounting frame 1 and the pins 100 are inserted to abut against the abutting parts. A handle is also provided on the fan profile 32. The handle is located on the front and can be used to install a hook lock 4. The hook lock 4 is directly connected to the handle and the movable hook 42 is driven to move up and down. Multiple hook locks 4 can also be installed, and a transmission rod is set on the side of the fan profile 32 where the hook lock 4 is located. The handle is used to connect the transmission rod, and the transmission rod is used to connect each hook lock. This structure is the existing structure of screen windows and will not be described in detail.

[0027] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
