Description

Technical Field

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

[0002] Sliding doors and windows have the advantages of not occupying additional indoor and outdoor space, high daylighting rate, and wide field of vision. However, after the existing sliding doors and windows are pushed and closed with the side frames of the doors and windows, there is a large gap between the side and the bottom frame of the doors and windows. Even if the gap between the bottom frame of the doors and windows and the door and window body can be sealed by setting a sealing strip, as the sealing strip is worn, the gap between the bottom frame of the doors and windows and the door and window body becomes larger and larger, affecting the sealing and sound insulation effects.

[0005] Preferably, a shaft rod is mounted on the load-bearing frame, a shaft sleeve is slidably mounted on the shaft rod, and the load-bearing wheel is rotatably mounted on the shaft sleeve.

[0006] Preferably, both ends of the shaft rod are provided with springs, and both ends of the spring are respectively connected to the shaft sleeve and the inner side of the load-bearing frame.

[0007] Preferably, the lower slide rail is provided with a load-bearing slide groove, and the load-bearing wheel rolls in the load-bearing slide groove.

[0008] Preferably, the sealing strip is a hollow structure and is provided with elastically retractable folds.

[0009] Beneficial Effects

[0010] The utility model provides a side pressure sliding door and window, which has the following beneficial effects:

[0011] This device provides guide grooves on the upper and lower slide rails, and guide wheels that match the guide grooves are provided on the upper and lower parts of the movable leaf, so that the movable leaf moves toward the closing direction and is close to the fixed leaf, thereby making the sealing strip of the movable leaf press against the fixed leaf. Similarly, when the movable leaf moves toward the opening direction, the movable leaf is separated from the contact with the fixed leaf. Therefore, this device not only ensures the sealing of the movable leaf when it is closed, but also reduces the resistance of the movable leaf when it moves, and avoids the wear caused by the long-term friction between the sealing strip and the fixed leaf.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-7The utility model provides a technical solution: a side-pressure sliding door and window, comprising a fixed sash 1, a lower slide rail 2 is provided at the lower part of the fixed sash 1, an upper slide rail 5 is provided at the upper part, a movable sash 4 is slidably connected between the upper slide rail 5 and the lower slide rail 2, the upper slide rail 5 and the lower slide rail 2 are both provided with guide grooves 15, a group of guide frames 7 are installed on the upper part of the movable sash 4, an upper guide wheel 6 is rotatably installed on the guide frame 7, the upper guide wheel 6 contacts the inner wall of the guide groove 15 of the upper slide rail 5, a group of load-bearing frames 8 are installed at the lower part of the movable sash 4, a load-bearing wheel 13 is rotatably installed on the load-bearing frame 8, lower guide wheels 9 are rotatably installed on both sides of the load-bearing frame 8, the lower guide wheels 9 contact the inner wall of the guide groove 15 of the lower slide rail 2, the guide groove 15 is bent toward one side of the opening 14 near the opening 14 of the fixed sash 1, and a sealing strip 3 is provided on the movable sash 4;

[0022] When the movable sash 4 slides in the opening direction between the upper slide rail 5 and the lower slide rail 2, the guide groove 15 squeezes the upper guide wheel 6 and the lower guide wheel 9, so that the movable sash 4 moves away from the fixed sash 1, and the sealing strip 3 is out of contact with the fixed sash, thereby reducing the sliding resistance of the movable sash 4 and avoiding wear caused by friction between the sealing strip 3 and the fixed sash 1. When the movable sash 4 slides in the closing direction, the guide groove 15 squeezes the guide groove 15 squeezes the upper guide wheel 6 and the lower guide wheel 9, so that the movable sash 4 is close to the fixed sash 1, and the sealing strip 3 is in close contact with the fixed sash 1.

[0023] Furthermore, a shaft 10 is mounted on the load-bearing frame 8, a shaft sleeve 12 is slidably mounted on the shaft 10, and the load-bearing wheel 13 is rotatably mounted on the shaft sleeve 12;

[0024] Furthermore, springs 11 are mounted on both ends of the shaft rod 10, and both ends of the spring 11 are respectively connected to the shaft sleeve 12 and the inner side of the load-bearing frame 8;

[0025] Furthermore, the lower slide rail 2 is provided with a load-bearing slide groove 16, and the load-bearing wheel 13 rolls in the load-bearing slide groove 16;

[0026] When the movable fan 4 slides between the upper slide rail 5 and the lower slide rail 2, the load-bearing wheel 13 rolls in the load-bearing slide groove 16. When the movable fan 4 moves laterally toward or away from the fixed fan 1, the load-bearing wheel 13 slides laterally on the shaft 10 through the shaft sleeve 12. Through the setting of the above technical solution, the load-bearing wheel 13 can be prevented from sliding laterally on the lower slide rail 2, thereby reducing the wear of the load-bearing wheel 13.

[0027] Furthermore, the sealing strip 3 is a hollow structure and is provided with elastically retractable folds 17;

[0028] The above technical solution can be used to ensure that the sealing strip 3 is in close contact with the fixed fan 1 .

[0029] Embodiment: When the movable fan 4 slides between the upper slide rail 5 and the lower slide rail 2 in the opening direction, the guide groove 15 squeezes the upper guide wheel 6 and the lower guide wheel 9, so that the movable fan 4 moves away from the fixed fan 1, and the sealing strip 3 is out of contact with the fixed fan, thereby reducing the sliding resistance of the movable fan 4 and avoiding the wear caused by the friction between the sealing strip 3 and the fixed fan 1. When the movable fan 4 slides in the closing direction, the guide groove 15 squeezes the guide groove 15 squeezes the upper guide wheel 6 and the lower guide wheel 9, so that the movable fan 4 is close to the fixed fan 1, and the sealing strip 3 is in close contact with the fixed fan 1. At the same time, when the movable fan 4 slides between the upper slide rail 5 and the lower slide rail 2, the load-bearing wheel 13 rolls in the load-bearing slide groove 16. When the movable fan 4 moves laterally toward or away from the fixed fan 1, the load-bearing wheel 13 slides laterally on the shaft rod 10 through the shaft sleeve 12, thereby avoiding the load-bearing wheel 13 from sliding laterally on the lower slide rail 2 and reducing the wear of the load-bearing wheel 13.
