Description

Technical Field

[0001] This utility model belongs to the technical field of door and window accessories, specifically relating to a door and window side-pressure inward tilting upper wheel pull rod. Background Technology

[0002] As building doors and windows increasingly demand higher standards for air tightness, water tightness, and safety, door and window products are continuously being optimized in terms of structural design and functional implementation. Among them, inward-opening windows are widely used in residential, office, and public buildings due to their reasonable opening angle, strong safety, and space-saving features, especially in scenarios requiring air tightness and water tightness testing (i.e., lateral pressure testing).

[0003] Traditional tilt-and-turn windows typically employ hinged or limit arm mechanisms for opening and positioning, with sliding guidance often relying on bottom or side pulleys. However, during lateral pressure testing for airtightness, windows often require maintaining a high degree of airtightness and positioning stability, and existing structures generally suffer from the following deficiencies:

[0004] Traditional upper wheel designs are mostly fixed connection structures, which cannot adapt to the angle changes that occur during the opening and closing of door and window sashes, and are prone to problems such as jamming, derailment or uneven movement; the upper wheel and frame are mostly rigidly connected, lacking a movable buffer structure, which can easily lead to structural fatigue and deformation after long-term use, and even cause the pulley to fall off, affecting the service life of the door and window.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0019] like Figures 1 to 3 As shown, a door / window side-pressure tilt-in upper wheel pull rod includes an outer frame 10 and a door / window sash 20. The door / window sash 20 is installed in the outer frame 10 and is connected to the outer frame 10 by a plurality of upper wheel assemblies 30. In use, when the door / window is subjected to a side-pressure test or daily opening operation, the door / window sash 20 tilts and rotates inward relative to the outer frame 10 under the guidance of the upper wheel assemblies 30, thereby realizing the tilt-in opening function.

[0020] In specific implementation, the upper wheel assembly 30 includes a mounting base 31, a connecting rod 32, and an upper wheel bracket 33. One end of the connecting rod 32 is movably connected to the mounting base 31, and the other end of the connecting rod 32 is movably connected to the upper wheel bracket 33. The upper wheel bracket 33 has movable upper wheels 34 symmetrically connected on both sides for sliding in the guide rail on the outer frame 10. The mounting base 31 is mounted on the door / window sash 20 for moving with the window sash, and the upper wheel bracket 33 is mounted on the outer frame 10 for cooperating with the guide rail to achieve the guiding function. In use, when the door and window are closed or under sealing pressure, the door and window sash 20 remains vertical. The movable upper wheel 34 in the upper wheel assembly 30 provides positioning and support in the guide rail. When the door and window sash 20 changes from the closed state to the inward opening state, the door and window sash 20 rotates around the lower pivot. The connecting rod 32 installed on it drives the upper wheel bracket 33 to swing, thereby causing the movable upper wheel 34 to slide along the guide rail of the outer frame 10, completing the smooth opening process of the window sash. Since the two ends of the connecting rod 32 are movable connection structures, they can be adaptively adjusted according to the rotation angle of the door and window sash 20, avoiding jamming, deformation or structural damage caused by rigid connection, ensuring smooth movement and structural durability, and achieving the effect of preventing falling off.

[0021] In practical implementation, one end of the mounting base 31 has a first movable through hole 311, and the end of the connecting rod 32 facing the mounting base 31 has a first pull rod through hole 321. The first pull rod through hole 321 and the first movable through hole 311 are hinged together by fasteners. One end of the upper wheel bracket 33 has a second movable through hole 331, and the end of the connecting rod 32 facing the upper wheel bracket 33 has a second pull rod through hole 322. The second pull rod through hole 322 and the second movable through hole 331 are hinged together by fasteners. The perforations 331 are hinged together by fasteners, so that the connecting rod 32 can be movably connected between the mounting base 31 and the upper wheel bracket 33. In use, when the door and window sash 20 rotates from the closed state to the inward open state, the connecting rod 32 installed on it moves together with the door and window sash 20, causing the upper wheel bracket 33 to swing accordingly, so that the movable upper wheel 34 in the upper wheel assembly 30 slides along the track in the guide rail of the outer frame 10, thereby realizing the smooth opening process of the window sash.

[0022] In practical implementation, the upper wheel bracket 33 has symmetrically provided first upper wheel through holes 332 on both sides, and the movable upper wheel 34 has a second upper wheel through hole 341 in the middle. The first upper wheel through holes 332 and the second upper wheel through holes 341 are correspondingly arranged and are hinged together by fasteners, so that the two movable upper wheels 34 can be movably connected to both sides of the upper wheel bracket 33, forming a support pulley structure that can rotate freely in the guide rail. In use, when the door or window is opened or a side-pressing action is performed, the movable upper wheel 34 slides horizontally in the guide rail of the outer frame 10, and can also rotate adaptively according to the slight tilt angle of the guide rail, thereby effectively reducing sliding resistance, improving sliding smoothness, and ensuring that the window sash is stably stressed during the tilting process.

[0023] In practical implementation, the upper wheel bracket 33 has symmetrical recessed locking positions 333 on both sides. The locking positions 333 are equipped with mounting locking positions 35. The mounting locking positions 333 are hinged to the locking positions 333 by fasteners. In use, the mounting locking positions 35 and the upper wheel bracket 33 form an auxiliary positioning or limiting structure. When the movable upper wheel 34 slides to the limit position in the guide rail or the window sash is at a specific opening angle, the mounting locking positions 35 can provide structural limiting and anti-detachment function for the upper wheel bracket by rotation or abutment.

[0024] In practical implementation, the surface of the mounting base 31 is provided with a number of mounting holes 312. The mounting base 31 is set on the door and window sash 20 and is connected and fixed to the door and window sash 20 by fasteners passing through the mounting holes 312. Through this structural design, the connection and installation between the mounting base 31 and the door and window sash 20 is convenient, the disassembly is simple, and the structure is stable.

[0025] In practical implementation, a limiting component 36 is movably connected to the surface of the mounting base 31. The front end of the limiting component 36 is connected to the end of the connecting rod 32. During use, when the door / window sash 20 is opened or closed, and the connecting rod 32 moves accordingly, the limiting component 36 works in conjunction to guide, buffer, or restrict the movement path of the end of the connecting rod 32, thereby preventing the connecting rod 32 from swinging excessively, dislodging, or structurally damaged during large movements.

[0026] In summary, the door / window sash 20 and the outer frame 10 are connected by several upper wheel assemblies 30. Each upper wheel assembly 30 includes a mounting base 31, a connecting rod 32, and an upper wheel bracket 33. One end of the connecting rod 32 is movably connected to the mounting base 31, and the other end is movably connected to the upper wheel bracket 33. Movable upper wheels 34 are symmetrically connected to both sides of the upper wheel bracket 33. The mounting base 31 is mounted on the door / window sash 20, and the upper wheel bracket 33 is mounted on the outer frame 10. This utility model's door / window side-pressing and tilting upper wheel tie rod provides reliable guidance, positioning, and load-bearing functions when the door / window is tilted inward or subjected to sealing side-pressing operations. The connecting rod uses a double-end movable connection method, which can adapt to the rotational changes of the door / window sash, ensuring smooth movement and avoiding structural interference. The upper wheel bracket, through the cooperation of the movable upper wheel and the guide rail, achieves efficient and stable sliding. The cooperation between the mounting base and the limiting components further enhances the structural stability and safety.
