Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a thermally broken side-pressure window system. Background Technology

[0002] Sliding doors and windows are a common type of door and window. Their design features, such as not taking up indoor space, being aesthetically pleasing, and providing ventilation, make them widely used in modern buildings. However, due to their sliding structure, sliding doors and windows often have poor sealing performance. Therefore, a type of side-pressure sliding door and window is now popular. This type mainly uses a side-pressure device installed on the door and window to apply pressure to the sliding sash when it is closed, causing the sliding sash to slide laterally. This side-pressure device presses the sliding sash against the outer frame to form a tight connection, thus providing a good sealing effect for the interior. Referring to the prior art with announcement number CN221609793U, the general principle of the existing side-pressure window is as follows: when the movable sash needs to be closed, the movable sash is slid to the designated position, and then by rotating the handle, the transmission structure in the transmission housing is driven to operate, which drives the transmission rod to move longitudinally, thereby driving the side-pressure device to switch to lateral movement, so that the movable sash moves horizontally to press against the outer frame and the mullion.

[0003] The existing technology has the following disadvantages: (1) There are not enough locking points, and the locking points are only set on one side of the movable fan; (2) Most of the side pressure devices are sliding friction, which has high resistance, is not convenient to use and is not smooth to operate; (3) If the thermally broken aluminum structure is adopted, the overall mass of the movable fan is large and the resistance is even greater, and the existing side pressure device cannot meet the usage requirements at all; (4) The side pressure displacement stroke is small and the sealing structure is not perfect, the air tightness is not good, and there is room for improvement in sealing performance.

[0008] In some embodiments, the first locking device includes a third connecting rod, a third base, a third drive shaft, a third bushing, a fourth bushing, a third sliding plate, and a locking hook assembly. The third connecting rod is connected to the transmission mechanism. The third base and the third connecting rod are both installed on the movable fan, with the third connecting rod located at the bottom of the third base. The third sliding plate is movably installed on the third base and is limited to the third base. The locking hook assembly is installed on the third sliding plate and cooperates with the center latch.

[0017] The beneficial effects of this utility model are: 1. This utility model provides a novel thermal break side-pressure window system. This thermal break side-pressure window system integrates thermal break aluminum structure and side-pressure structure, combining the advantages of sliding windows and casement windows. It has many advantages such as excellent heat insulation performance, significant energy saving effect, good sound insulation effect, convenient operation and space saving, high sealing and safety, and wide applicability.

[0018] 2. When the side-pressure device of the thermally broken side-pressure window system of this utility model is working, the movable sash is displaced by 7mm, while most side-pressure displacements on the market do not exceed 5mm. A larger displacement results in higher sealing performance. Furthermore, the second rubber strip of the movable sash presses against the upper and lower tracks, forming the first seal; the fourth profile of the movable sash presses against the first and third rubber strips, forming the second seal (a crucial seal); the fourth rubber strip of the movable sash presses against the second pressure line of the fixed sash, forming the third seal. Thus, after the side-pressure device is operational, the entire window sash system forms a three-layer sealing structure from the inside out. According to testing (test method reference GB / T 7106-2019), the airtightness of the thermally broken side-pressure window system of this utility model reaches level 8 (standard level reference GBT31433-2015), which is the highest standard for window sashes.

[0019] 3. The upper pulley mechanism, lower pulley mechanism, first locking device and second locking device of the thermally broken side-pressure window system proposed in this utility model are all equipped with rolling bushings. By making extensive use of rolling bushings, sliding friction is transformed into rolling friction, reducing friction and improving smoothness, so as to achieve high load-bearing capacity while ensuring a light operating feel.

[0054] The advantages of this novel thermal break side-pressure window system compared to existing technologies include at least the following: 1. This utility model provides a novel thermal break side-pressure window system. This thermal break side-pressure window system integrates thermal break aluminum structure and side-pressure structure, combining the advantages of sliding windows and casement windows. It has many advantages such as excellent heat insulation performance, significant energy saving effect, good sound insulation effect, convenient operation and space saving, high sealing and safety, and wide applicability.

[0055] 2. When the side-pressure device 5 of the thermally broken side-pressure window system of this utility model is working, the movable sash 4 is displaced, with a side-pressure displacement of 7mm. Most side-pressure displacements on the market do not exceed 5mm; a larger displacement results in higher sealing performance. Furthermore, the second rubber strip 44 of the movable sash 4 presses against the upper track 11 and the lower track 12, forming the first seal; the fourth profile 41 of the movable sash 4 presses against the first rubber strip 17 and the third rubber strip 25, forming the second seal (a crucial seal); the fourth rubber strip 48 of the movable sash 4 presses against the second pressure line 31 of the fixed sash 3, forming the third seal. Thus, after the side-pressure device 5 is working, the entire window sash system forms a three-layer sealing structure from the inside out. According to testing (test method reference GB / T 7106-2019), the airtightness of the thermally broken side-pressure window system of this utility model reaches level 8 (standard level reference GBT31433-2015), which is the highest standard for window sashes.

[0056] 3. The upper pulley mechanism 51, lower pulley mechanism 52, first locking device 6 and second locking device 7 of the thermal break side-pressure window system proposed in this utility model are all equipped with rolling bushings. By making extensive use of rolling bushings, sliding friction is transformed into rolling friction, reducing friction and improving smoothness, so as to achieve high load-bearing capacity while ensuring a light operating feel.

[0057] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
