[0004] For example, the patent application No. 2015105015309 discloses a sealed sliding window. The end portions of the upper track frame and the lower track frame of the sealed sliding window are provided with sealing pieces, the sealing pieces cover the outer end openings of the window sliding grooves, the left vertical frame and the right vertical frame of the window are respectively provided with sealing strip frames, the sealing strip frames are provided with rubber sealing strips, the lower track frame is provided with a lower track rubber sealing strip in the internal gap, the upper track frame at the joint of the left window and the right window is provided with an upper wind stop that can be elastically deformed, the upper wind stop covers the end gap of the upper track frame, and the lower track frame is provided with a lower wind stop, the lower wind stop covers the end gap of the lower track frame. The sealed sliding window disclosed by the patent application improves the air tightness by means of the rubber sealing strips on the left and right sides. However, a large amount of friction will occur when the sliding window is frequently translated for a long time, which will cause the rubber sealing strips to wear out and need to be replaced regularly. Based on the technical problems existing in the prior art that the rubber sealing strips are used to improve the air tightness of the window, the present application provides a high-air-tightness sliding window that can effectively solve the technical problems.

[0038] Reference is made to the accompanying drawings Figures 6-9 The upper rail profile 201 and the lower rail profile 202 are arranged at the upper end and the lower end of the window frame 1 below the fixed window 2, the lower end of the upper rail profile 201 and the upper end of the lower rail profile 202 are provided with a plurality of sliding slots 203 which are parallel in front and back, and each sliding slot 203 is provided with a pair of movable windows 3, so that the plurality of pairs of movable windows 3 can move in parallel along the corresponding sliding slots 203 and will not hinder each other. The convex edges 204 extending downward are arranged at both ends of the sliding slot 203 of the upper rail profile 201, so that the convex edges 204 on both sides of the sliding slot 203 of the upper rail profile 201 can abut with the two abutting wheels 3033 of the two guide wheel sets 303, thereby playing a guiding and limiting role, ensuring that the movable window 3 can move centrally in the sliding slot 203, and then the rubber strip pressing grooves 205 are formed on the inner side surface of the convex edges 204 below the abutting wheels 3033.

[0039] The roller rail 206 is fixedly installed on the bottom wall of the sliding slot 203 of the lower rail profile 202, so that the rollers on both sides of the roller pair 305 can simultaneously act on the two side surfaces of the roller rail 206. In the specific design, the two sides of the roller rail 206 are designed as inclined surfaces, and the two rollers in each roller pair 305 are also designed as inclined surfaces in a mirror image, so that in the process of acting on the two inclined surfaces of the roller rail 206, on the one hand, the roller pair 305 can effectively bear the entire movable window 3, and on the other hand, it can also ensure that the movable window 3 moves in the axial direction of the sliding slot 203 as much as possible during translation, thereby improving the stability of the movable window 3 during the pushing and pulling process. Similarly, the convex edges 204 extending upward are arranged at both ends of the sliding slot 203 on the lower rail profile 202, and the rubber strip pressing grooves 205 are also formed on the inner side surface of the convex edges 204.

[0040] The wedge-shaped strip 306 is arranged on both sides of the opening end of the horizontal section 302 above the movable window 3, and a sealing rubber strip 3061 is arranged on the side of the wedge-shaped strip 306 facing the corresponding convex edge 204, which matches the rubber strip pressing groove 205. A row of guide posts 307 is connected to each wedge-shaped strip 306, and the guide posts 307 are extended out of the guide holes on the side of the opening end of the horizontal section 302, and then a spring 308 is further connected between the side of the sliding slot 203 and the wedge-shaped strip 306. Similarly, the wedge-shaped strip 306 is arranged on both sides of the opening end of the horizontal section 302 below the movable window 3, and a sealing rubber strip 3061 is arranged on the side of the wedge-shaped strip 306 facing the corresponding convex edge 204, which matches the rubber strip pressing groove 205, and then the wedge-shaped strip 306 is also connected to the side of the opening end of the horizontal section 302 below through the spring 308 and the guide post 307.

[0041] Reference is made to the accompanying drawings Figure 10 and the accompanying drawings Figure 11 A gear 309 is arranged in each of the vertical sections 301 of the two movable windows 3 approaching each other, and a notch is formed on the side of each of the vertical sections 301 approaching each other, so that the side end of the gear 309 can extend out of the vertical section 301 through the notch, and when the two movable windows 3 are completely closed together, the two gears 309 can mesh with each other. Each gear 309 is rotatably arranged in the vertical section 301 through a rotating shaft 310, and one end of the rotating shaft 310 extending out of the vertical section 301 is connected with a handle 311 and a locking member 312, and the vertical section 301 of the other movable window 3 is fixed with a clamping member acting with the locking member 312. During the process of closing and locking the two movable windows 3, the user only needs to rotate the rotating shaft 310 by about 90° through the handle to make the locking member 312 rotate into the clamping member, thereby realizing the fixed connection of the two movable windows 3.

[0042] Two center-symmetrically arranged movable rods 313 are rotatably connected to each gear 309, and a pulling rod 314 vertically arranged in the vertical section 301 is rotatably connected to each end of each movable rod 313. One pulling rod 314 extends upward along the vertical section 301 to the upper end opening of the horizontal section 302 above, and the other pulling rod 314 extends downward to the lower end opening of the horizontal section 302 below, and a trapezoidal extrusion block 315 is fixedly connected to the end of each pulling rod 314 extending to the horizontal section 302, and the inclined surfaces on both sides of the trapezoidal extrusion block 315 can act on the two wedge-shaped strips 306 in the upper end opening of the horizontal section 302.

[0043] The specific use steps and working principle of the high-air-tightness sliding window disclosed in Embodiment 1 are as follows:

[0044] When the two movable windows 3 are not closed and are set in the same sliding slot 203, the two wedge-shaped strips 306 in the upper and lower horizontal profiles 302 will be drawn to the middle due to the support force of the springs 308, and the sealing rubber strips 3061 on the wedge-shaped strips 306 will leave a certain gap with the rubber strip pressing grooves 205 on the corresponding convex edges 204. In this state, pushing the movable window 3 will not cause the sealing rubber strips 3061 to contact the upper rail profile 201 and the lower rail profile 202, and the guide wheel set 303 above the movable window 3 will cause the abutting wheels 3033 at both ends of the rotating strip 3031 to abut against the inner walls of the two convex edges 204 in front of and behind the upper rail profile 201 under the action of the torsion spring, so as to ensure that the movable window 3 can move in the middle of the sliding slot 203. At the same time, due to the action between the multiple groups of roller pairs 305 on the roller mounting strip 304 and the roller rail 206, on the one hand, the movable window 3 can be ensured to move in the middle of the sliding slot 203, and on the other hand, the roller pairs 305 can bear the entire movable window 3, so that the movable window 3 can be stably and low-resistance translated in the window frame 1.

[0045] When it is necessary to close and seal the two movable windows 3, the two movable windows 3 are first pushed to approach each other until the vertical profiles 301 on the two movable windows 3 are attached together, and at this time, the gears 309 on the two movable windows 3 are also engaged with each other. Then, the user rotates the handle 311 by 90° or so in the direction of locking the window, at this time, the lock catch 312 connected to the same rotating shaft 310 as the handle 311 turns into the clamping member in the other movable window 3, so as to realize the fixed connection of the two movable windows 3.

[0046] At the same time, during the rotation of the handle 311, the rotating shaft 310 will cause the gears 309 inside the vertical profiles 301 to rotate, and due to the meshing transmission action between the gears, the gears 309 in the other movable window 3 also rotate synchronously. During the rotation of the gears 309, the two movable rods 313 connected to the gears 309 can simultaneously pull the upper and lower pulling rods 314 vertically to the position of the rotating shaft 310, and then the upper trapezoidal extrusion block 315 will act on the two wedge-shaped strips 306 in the upper horizontal profile 302, and the lower trapezoidal extrusion block 315 will act on the two wedge-shaped strips 306 in the lower horizontal profile 302, so that each pair of wedge-shaped strips 306 moves outward (i.e. moves towards the corresponding convex edge 204) against the support force of the springs 308, until the sealing rubber strips 3061 on the wedge-shaped strips 306 are pressed into the rubber strip pressing grooves 205 on the corresponding convex edges 204. At this time, the track gap between the movable window 3 and the upper rail profile 201 and the lower rail profile 202 is tightly sealed, and the external airflow cannot enter the room through the track gap in strong wind weather, which achieves an excellent air-tight sealing effect.

[0047] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement and improvement etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
