Description

Technical Field

[0001] The utility model relates to the technical field of side-pressure sliding windows, in particular to a lower rail of a side-pressure sliding window. Background Art

[0002] Sliding doors and windows have the advantages of not occupying indoor space, beautiful appearance, flexible opening, etc. The sliding doors and windows are composed of an outer frame and a movable leaf. The outer frame is provided with a track, and a pulley is installed on the movable leaf. The movable leaf is moved by the pulley and the track. Reference Publication (Announcement) No.: CN220133762U is a side-pressure sliding door and window. The side pressure is realized on the basis of the original sliding window, and a sealing strip is arranged on a baffle on one side of the side pressure of the outer frame. When closing, the movable leaf is close to the baffle on one side of the outer frame to press the sealing strip, thereby achieving sealing, preventing water ingress, air leakage and other problems of the internal structure;

[0003] However, in order to realize the side pressure action, the bottom pulley of the existing side pressure sliding window needs to be set as a laterally movable swing wheel. Such a swing wheel is prone to lateral displacement during normal sliding, thereby detaching from the guide rail. At the same time, the existing side pressure sliding window will still have rainwater penetration due to improper installation of the sealing strip or aging due to long-term use. In addition, the lower track of the existing side pressure sliding window is generally not provided with a drainage structure. Once rainwater enters the lower track profile, it is difficult to drain, which easily causes rainwater backflow. Utility Model Content

[0020] The utility model discloses a side-pressure sliding window lower rail, by arranging a vertical plate 4 on a sliding platform 2, utilizing the vertical plate 4 to limit a pulley member 40 to prevent it from being laterally displaced inward, the vertical plate 4 cooperates with a guide bar 10 to limit the pulley member 40, thereby preventing it from being separated from the guide bar 10, and at the same time a drainage step 3 is arranged on the sliding platform 2, and a water retaining plate 5 is arranged to prevent rainwater from flowing back, the drainage step 3 gradually downwards from the indoor end to the outdoor end, which is conducive to the flow and discharge of rainwater, and is conducive to the discharge of rainwater entering the lower rail profile 1, and preventing rainwater from flowing back, and a front support plate 6 and a water retaining plate 5 are respectively arranged before and after the drainage step 3, thereby forming a water storage tank for temporarily storing rainwater.

[0021] In this embodiment, a sliding sash 50 is also included, a groove is provided at the bottom of the sliding sash 50, a pulley member 40 slidably connected to the guide bar 10 is provided in the groove, a first sealing strip 31 abutting against the vertical plate 4 is provided on the rear side wall of the groove, and a second sealing strip 32 abutting against the front side wall of the groove is provided on the rear side of the water retaining plate 5. In addition, an outer window frame is also included. The outer window frame and the sliding sash 50 both belong to the existing side-pressure sliding window structure. The pulley member 40 is also a pulley accessory that can be displaced laterally used in the existing side-pressure sliding window. The pulley member 40 is installed at In the groove at the bottom of the lower profile of the sliding window 50, there are ribs extending downward on the front and rear sides of the lower side of the lower profile. The first sealing strip 31 is arranged on the rear rib and abuts against the vertical plate 4 when the sliding window is pressed closed. The second sealing strip 32 is arranged on the rear side of the water retaining plate 5 and abuts against the front rib of the lower profile when the sliding window is pressed closed, thereby improving the sealing performance. At the same time, in the closed state, the first sealing strip 31 and the second sealing strip 32 form a closed loop for the sliding platform 2 part, so that the sliding platform 2 and the sliding window form an air cavity to prevent rainwater from entering.

[0022] In this embodiment, the pulley member 40 includes a shell 41, and the vertical plate 4 is in contact with the shell 41. When the push-pull fan 50 is in a normal sliding state, the vertical plate 4 and the shell 41 can slide in contact.
