[0018] The following further detailed description of the utility model is provided in conjunction with the drawings, so that those skilled in the art can implement it with reference to the text of the specification.

[0019] It should be noted that, unless otherwise specified, the experimental methods described in the following implementation schemes are all conventional methods, and the reagents and materials, unless otherwise specified, can all be obtained from commercial channels; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0020] As Figures 1 to 3 shown, the present invention provides a window with an invisible anti-theft net, including: a window frame 1 and two window sashes 3 arranged in parallel and slidably connected within the window frame 1. When the two window sashes 3 are completely staggered, the window frame 1 can be exactly closed; anti-theft nets 2 are arranged on the sides of the two window sashes 3 facing away from each other, and the length of the anti-theft nets 2 is adjustable; accommodating cavities for accommodating the anti-theft nets 2 are respectively formed on both sides of the window frame 1; one end of the anti-theft net 3 near the indoor side is fixedly connected to the corresponding window sash 2, and the other end is snap-fitted to the inner wall of the accommodating cavity, and the side wall 11 of the corresponding accommodating cavity facing the indoor side is detachably connected to the window frame 1; both ends of the anti-theft net 3 near the outdoor side are respectively fixedly connected to the corresponding window sash 2 and the inner wall of the accommodating cavity.

[0021] In this technical solution, like a traditional sliding window, the two window sashes 3 can slide parallel within the window frame 1, one of the two window sashes 3 is close to the indoor side and the other is close to the outdoor side; when the two window sashes 3 overlap, half of the space of the window frame 1 is in an open state; when the two window sashes 3 are completely staggered, the window frame 1 can be exactly closed. The window sash 3 drives the anti-theft net 2 beside it to extend or retract during the sliding process. When the two window sashes 3 are completely staggered, as Figure 1 and Figure 3 shown, the two anti-theft nets 2 are both in an extended state or both in a retracted state. As Figure 2As shown in the figure, when the two window sashes 3 overlap and are located on one side of the window frame 1, one of the anti-theft nets 2 is in an extended state, and the other anti-theft net 2 is in a retracted state. When the anti-theft net 2 is in the retracted state, it is exactly located in the corresponding accommodation cavity to hide the anti-theft net 2. To facilitate escape in case of a fire, one end of the anti-theft net 3 near the indoor side is fixedly connected to the corresponding window sash 2, and the other end is detachably connected to the inner wall of the accommodation cavity, and the side wall 11 of the corresponding accommodation cavity facing the indoor side is detachably connected to the window frame 1; when a fire occurs, first remove the side wall 11 of the accommodation cavity on the indoor side, then separate the anti-theft net 2 from the inner wall of the accommodation cavity, and retract the anti-theft net 2 towards the side of the window sash 3, then one can escape through the window to the outside. During daily use, the anti-theft net 2 cannot be removed from the outdoor side. Preferably, the side wall 11 of the accommodation cavity facing the indoor side and the window frame 1 can be quickly connected by a buckle and is easy to disassemble.

[0022] In another technical solution, two parallel tracks are respectively arranged on the inner top surface and the inner bottom surface of the window frame 1, and one window sash 2 is slidably connected to each track. The sliding connection manner between the window sash 2 and the track can adopt the structure used in a conventional sliding window. Both tracks extend into the accommodation cavities on both sides of the window frame 1 to ensure that the two anti-theft nets 2 can be retracted and extended freely.

[0023] In another technical solution, as Figure 4 shown, the anti-theft net 2 is a telescopic anti-theft net 21, which includes a plurality of vertical rods 211 arranged at intervals, and multiple sets of telescopic units 212 are arranged at intervals in the height direction between two adjacent vertical rods 211. The top and bottom of the vertical rod 211 are respectively slidably connected to the corresponding tracks. The telescopic unit 212 can adopt a diamond structure as Figure 4 shown, which is formed by sequentially rotatingly connecting four rods, and then respectively rotatingly connecting to the vertical rods 211 on both sides. By changing the angle between the rods, the distance between the two vertical rods 211 is adjusted; the telescopic unit 212 can also adopt other conventional telescopic structures such as a two-link structure.

[0024] In another technical solution, as Figure 5As shown, the anti-theft net 2 is a foldable anti-theft net 22, which includes a plurality of steel mesh sheets hinged in sequence. Sliders that are slidably connected to the window frame are respectively rotatably connected to the middle of the top and bottom of the steel mesh sheets. When the anti-theft net 2 is unfolded under the pulling of the window sash 3, each of the steel mesh sheets is unfolded from the superposed state to the parallel state in sequence. At this time, each of the steel mesh sheets rotates 90 degrees relative to each of the sliders; when the anti-theft net 2 is folded under the pushing of the window sash 3, each of the steel mesh sheets rotates from the parallel state to the superposed state in sequence. At this time, each of the steel mesh sheets rotates 90 degrees in the reverse direction relative to each of the sliders; during the above process, each of the sliders always maintains a sliding connection with the window frame 1. The width of the steel mesh sheet is the same as the width of the accommodating cavity, so that each of the steel mesh sheets can be received in the accommodating cavity when they are superposed.

[0025] In another technical solution, the engagement connection between the anti-theft net 2 near the indoor side and the inner wall of the accommodating cavity is specifically realized through the following structure: As Figure 6 shown, a fixing plate 12 with a U-shaped horizontal cross-section and an opening facing the indoor side is provided in the accommodating cavity near the indoor side; a plurality of buckles 13 are arranged at intervals along the height direction inside the fixing plate 12; one end 23 of the anti-theft net 2 near the indoor side connected to the accommodating cavity is inserted into the fixing plate and fixed by each of the buckles 13. When it is necessary to disassemble the anti-theft net 2, after removing the side wall 11 of the accommodating cavity, the end 23 of the anti-theft net 2 connected to the accommodating cavity can be separated from each of the buckles 13 by applying a force in the direction towards the indoor side, without the need to use additional tools for disassembly, which is convenient for quick escape in case of emergency. During daily use, the lateral pushing and pulling force applied by the window sash 3 to the anti-theft net 2 does not affect the connection between the anti-theft net 2 and the fixing plate 12, and the anti-theft net 2 cannot be separated from the window frame 1 from the outdoor side. Preferably, a groove for inserting one side of the fixing plate 12 and the buckle 13 is provided at one end 23 of the anti-theft net 2 connected to the accommodating cavity, so as to form an interlaced and engaged state between one end 23 of the anti-theft net 2 connected to the accommodating cavity and the fixing plate 12, further increasing the stability between the anti-theft net 2 and the accommodating cavity. As Figure 6 shown, the horizontal cross-section of the buckle 13 is U-shaped, and its two sides are made of elastic materials and are respectively provided with clamping portions 14 bent inward. Grooves are respectively provided at one end of the anti-theft net 2 connected to the accommodating cavity corresponding to the two clamping portions 14.

[0026] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples described herein.
