It is characterized in that the opposite sides of the lower rail one and the lower rail two are connected by two connecting strips. Two support platforms are arranged at the upper end of the lower rail two. A lower rail three is connected to the upper end of the lower rail two through the two support platforms. The upper surface of the lower rail one is recessed and provided with a first track. Two second tracks are equidistantly arranged inside the lower rail three. The two second tracks are respectively directly above the corresponding support platforms.

[0006] Both the first track and the two second tracks have a symmetrical double-track structure.

[0007] As a preferred technical solution of the utility model, hair strip holes are arranged at the upper and lower ends on the left side and the middle part of the upper surface of the lower rail three.

[0008] As a preferred technical solution of the utility model, a sloping drainage platform is arranged at the right end of the lower rail two, and a baffle one is arranged at the right end of the lower rail three. The drainage platform and the baffle one form an invisible drainage structure.

[0009] As a preferred technical solution of the utility model, the right side of the lower rail two extends downward and is provided with a baffle two. A tearing opening is arranged between the lower rail two and the baffle two.

[0010] As a preferred technical solution of the present utility model, barbs are provided on the opposite sides of the two support platforms, and two opposite connecting ribs are provided on the lower surface of the lower rail three, and the two connecting ribs are respectively clamped with the corresponding barbs.

[0011] The working principle and beneficial effects of the present utility model are as follows:

[0012] The structure of the present utility model is simple and convenient to install. Through the symmetric double-rail structures of the first rail and the two second rails, the double rails are more balanced in force, smoother and more stable in pushing and pulling, and there is no noise during sliding, ensuring the safety performance. That is to say, the sliding window and the screen window are installed on the first rail and the two second rails. In this way, the screen window can not only be installed on the first rail, but also on the second rail far from the first rail, so that the effect of installing the screen window indoors or outdoors can be achieved. Through the design of the felt strip holes, the sealing performance of the window is better, and it can effectively block external dust, noise, etc. Through the design of the drainage platform and the baffle one combined to form an invisible drainage structure, the appearance is more beautiful, the drainage is smooth, and rainwater backflow can be prevented. Through the design of the tearing opening, it can be used as both a fixed lower rail and a flat lower rail.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment

[0019] As Figure 1 shown, this embodiment provides a lower rail of a six-rail sliding window, including a lower rail one 1 and a lower rail two 2 which are oppositely arranged. The opposite sides of the lower rail one 1 and the lower rail two 2 are connected by two connecting bars 3. Two supporting platforms 4 are provided at the upper end of the lower rail two 2. A lower rail three 5 is connected to the upper end of the lower rail two 2 through the two supporting platforms 4. Barbs 13 are provided on the opposite sides of the two supporting platforms 4. Two connecting ribs 14 are provided on the lower surface of the lower rail three 5 and are respectively clamped with the corresponding barbs 13. This not only ensures stable installation but also makes the installation more firm through the cooperation of the connecting ribs 14 and the barbs 13. The upper surface of the lower rail one 1 is recessed inward and is provided with a first track 6. Two second tracks 7 are equidistantly arranged inside the lower rail three 5. The two second tracks 7 are respectively directly above the corresponding supporting platforms 4. The first track 6 and the two second tracks 7 are both of a symmetric double-track structure. The double tracks are more balanced in force, smoother and more stable in pushing and pulling, and there is no noise during sliding, ensuring safety performance. That is to say, the sliding window and the screen window are installed on the first track 6 and the two second tracks 7. In this way, the screen window can be installed not only on the first track 6 but also on the second track 7 far from the first track 6, so that the effect of installing the screen window indoors or outdoors can be achieved.

[0020] Furthermore, hair strip holes 8 are provided at the upper and lower ends on the left side and the middle of the upper surface of the lower rail three 5. Through the design of the hair strip holes 8, the sealing performance of the window is better, and it can effectively block external dust, noise, etc.

[0021] A drain platform 9 is provided at the right end of the lower rail two 2 and is inclined. A baffle one 10 is provided at the right end of the lower rail three 5. The drain platform 9 and the baffle one 10 form an invisible drainage structure. The design of the invisible drainage structure makes the appearance more beautiful, the drainage is smooth, and it can also prevent rainwater from flowing back.

[0022] The right side of the lower rail two 2 extends downward and is provided with a baffle two 11. A tear-off opening 12 is provided between the lower rail two 2 and the baffle two 11. Through the design of the tear-off opening 12, the baffle two 11 can be torn off at any time. Of course, when not torn off, it can be used as a fixed lower rail. If the baffle two 11 is torn off through the tear-off opening 12, it can be used as a flat lower rail.

[0023] The structure of the utility model is simple and easy to install. The first track 6 and the two second tracks 7 are both symmetric double-track structures. The double tracks are more balanced in force, smoother and more stable in pushing and pulling, and there is no noise during sliding, ensuring the safety performance. That is to say, the sliding window and the screen window are installed on the first track 6 and the two second tracks 7. In this way, the screen window can be installed not only on the first track 6 but also on the second track 7 far from the first track 6, so that the effect of installing the screen window indoors or outdoors can be achieved. Through the design of the felt strip holes 8, the sealing performance of the window is better, and it can effectively block external dust, noise, etc. Through the design of the combination of the drainage platform 9 and the first baffle 10 to form an invisible drainage structure, the appearance is more beautiful, the drainage is smooth, and rainwater backflow can be prevented. Through the design of the tearing opening 12, it can be used as both a fixed lower rail and a flat lower rail. The lower rail of this sliding window has excellent wind resistance, sound insulation, waterproof, dustproof and drainage performance, is convenient to use, beautiful and generous, and has strong bearing capacity. The screen fan can be installed indoors or outdoors.

[0024] The above is only the preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
