Description

Detachable push-pull screen window for casement window track Technical Field The utility model relates to the technical field of casement window screens, in particular to a detachable push-pull screen window for a casement window track. Background Currently, the main window type of the market is two types of flat-open window and sliding window. The casement window is a window type which is opened by horizontally rotating a window sash inwards or outwards by taking a hinge (a hinge) as a supporting point. The window is characterized in that the window sash is connected with the window frame through a hinge to form a cantilever stress structure, so that the window can be completely closed or opened at a large angle. According to the opening direction, the two types of opening modes are divided into an inward opening type and an outward opening type, and part of modern products also have multiple opening modes such as upper suspension and lower suspension. Compared with a sliding window, the flat-open window has larger opening area and better ventilation effect, is locked by the adhesive tape at multiple points during closing, has better air tightness and water tightness, and can effectively isolate noise and rainwater infiltration. The screen window type of the casement window mostly adopts the forms of an inner casement screen window and an invisible winding drum sliding screen window, and the core design of the invisible winding drum sliding screen window is to store the screen in a hidden winding box through a winding drum mechanism. When the mosquito-proof screen is used, the gauze is pulled downwards to cover the window, and when the mosquito-proof screen is not used, the gauze is automatically rewound into the box, so that the invisible effect is realized, the ventilation mosquito-proof function is maintained, and the sight is not blocked. Invisible roll push-pull screens arranged on the inner side often need to maintain ventilation, and can intercept pollutants such as dust, pollen, bacteria, insect carcasses and the like in the air, and the pollutants are easy to grow bacteria and mold in a humid environment. The screen window of deposition can block up the mesh, leads to the circulation of air to be obstructed, and indoor ventilation efficiency declines. Thus, as the duration of use increases, the screen needs to be cleaned periodically to keep the room air and environment fresh. In the prior art, the invisible winding drum sliding screen window is high in disassembly difficulty, time and labor are wasted when the screen window is disassembled, and cleaning work becomes difficult. In the individual design, although the gauze can be detached for cleaning, the sliding rail and the sliding groove of the invisible winding drum sliding screen still remain pollutants such as dust, pollen and the like, so that the normal sliding operation of the screen is affected, and the defect that the screen is difficult to clean thoroughly exists. Disclosure of utility model The utility model provides a detachable sliding screen window for a casement window track, which aims to solve the technical problems that an invisible winding drum sliding screen window for a casement window is difficult to detach and difficult to clean thoroughly; the top of the inner side of the casement window frame is provided with an L-shaped buckling strip; The L-shaped buckling strip is fixedly arranged on the casement window frame in an inverted mode and forms a strip-shaped groove with the casement window frame, and the strip-shaped groove is matched with the strip-shaped bulge so as to ensure that the screen window frame can be embedded on the casement window frame; At least two rectangular accommodating cabins are arranged in the bottom of the casement window frame, strip-shaped through holes are formed in the outer side of each rectangular accommodating cabin, and movable fastening devices are arranged in each rectangular accommodating cabin; Each movable fastening device comprises a second spring and a spring plate, the spring plates transversely extend outwards and are fixedly connected with a push plate after penetrating through the strip-shaped through holes, so that the spring plates and the push plate can integrally move in the vertical direction along the strip-shaped through holes, and wedge-shaped buckle plates are fixedly connected to the push plate. Preferably, in the above technical solution, one end of the second spring is fixedly connected with the spring plate, and the other end is fixedly connected with the bottom of the rectangular accommodating bin. Preferably, in the above technical solution, an inner ring of the casement window frame is provided with an annular groove, so as to ensure that the screen window frame can be mounted on the casement window frame in an embedded manner; The bottom of the annular groove is provided with at least two spring grooves, and the spring grooves are arranged at positions close to th
