Description

Technical Field

[0001] The utility model belongs to the technical field of door and window hardware, and particularly relates to a locking hardware structure for opening a window sash. Background Art

[0002] The sliding inward-tilting window is a window that can be placed in three different positions: locked, sliding, and tilted by rotating the window handle to drive the linkage hardware mechanism inside the window.

[0003] The hardware generally includes a main transmission device 1, a transmission connection assembly, a plurality of first locking assemblies 3, an angle transmission device, a diagonal rod assembly, a hinge assembly and a guide rail assembly. In the existing structure, the hardware is all built-in structure, resulting in limited installation space and design space. Therefore, the number of angle transmission devices in the existing structure is two, that is, there are only two upper angle transmission devices 41, a first transmission connection rod 21 and a third transmission connection rod 23. The main transmission device 1 is connected to the two upper angle transmission devices 41 through the first transmission connection rod 21 and the third transmission connection rod 23. Therefore, only the upper part of the window sash can be set with a locking point. Because the lower part is not provided with an angle transmission device and a transmission connection assembly, no locking point can be set at the lower part. This structural form will affect the sealing performance, resulting in air leakage, and the heat insulation and sound insulation effects are relatively poor. Utility Model Content

[0004] The utility model provides a locking hardware structure for opening a window sash, which can solve the problems pointed out in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a main transmission, a transmission connection assembly, a plurality of first locking assemblies and an angle transmission, the number of the angle transmissions is four, which are respectively arranged at the four corners of the door leaf, including two upper angle transmissions and two lower angle transmissions, the lower angle transmission is provided with a second locking assembly, the second locking assembly includes a movable locking member connected to the lower angle transmission and a lock seat, the lock seat is provided with a limiting movable long hole cooperating with the movable locking member, and the outer side of the limiting movable long hole is provided with a notch for the movable locking member to enter and exit.

[0006] Preferably, the movable locking member is a movable locking shaft, and the limiting movable long hole is an elliptical long hole.

[0007] Preferably, the transmission connection assembly includes a first transmission connection rod and a second transmission connection rod which are transmission-connected to the main transmission, a third transmission connection rod between the two upper angle transmissions, and a fourth transmission connection rod between the upper angle transmission on the other side and the lower angle transmission; at least one third locking assembly is arranged on the first transmission connection rod, the second transmission connection rod, the third transmission connection rod and the fourth transmission connection rod.

[0008] Beneficial effect: The utility model provides a locking hardware structure for opening a window sash, with angle actuators respectively arranged at the four corners so that both the upper and lower parts have locking points, thereby improving the sealing performance after locking and effectively improving the sound insulation and heat insulation effects.

[0009] In addition, this design form makes it form a transmission system that is close to a "closed" type, so a third locking assembly can be set on the second transmission connecting rod and the fourth transmission connecting rod as needed, that is, corresponding locking points can be further added at the lower part as needed, thereby improving the locking performance and improving the sealing.
