Description

Technical Field

[0001] The utility model belongs to the field of rotating and opening doors and windows, and in particular relates to a structure of a split cover plate and a connecting rod. Background Art

[0002] Currently, the pin holes for rotating shutters and connecting rods are integral with the window sash profiles, which makes the assembly method of the window sash connecting rods more complicated, and the sealing between adjacent window sash vertical profiles is not perfect, and there is room for further improvement. Utility Model Content

[0003] The utility model provides a structure of a split cover plate and a connecting rod. The split cover plate added by the method can cover the joints of adjacent profiles for further sealing. At the same time, the assembly method of the connecting rod is very simple, which can ensure that each group of window sashes is very flat when closed.

[0004] It includes a connecting rod and a vertical profile of a window sash, the vertical profile of the window sash includes a large end half of the window sash and a small end half of the window sash, the split cover plate is a straight plate with a hinge pin hole, one end or both ends of the split cover plate are respectively hinged to the connecting rod, and the split cover plate is respectively fixedly connected to the outer surface of the large end half of the window sash by screws.

[0005] Furthermore, the split cover plate is a straight plate, which is fixedly connected to the outer surface of the large end half of each window sash by screws. A sealing strip snap-in is provided at one end of the straight plate, and a V-shaped sealing strip made of a material with good elasticity, such as a polyurethane film, is snap-connected to the sealing strip snap-in. A hinge pin hole is connected to the back of the sealing strip snap-in. A clamping platform is provided at the end of the other end of the straight plate, and a clamping groove for a hidden screw is formed between the clamping platform and the hinge pin hole, and a hidden cover plate with a hidden screw head is clamped or bonded in the clamping groove.

[0006] The steps of the connecting rod assembly method are: 1. Take split cover plates that are equal in number to each group of rotating window sashes and slightly longer in length than the vertical profile of the window sashes; 2. Arrange the split cover plates in parallel with a spacing equal to the wheelbase of the rotating window sashes; 3. One or both ends of the split cover plates are hinged to the connecting rods to form a fence-like frame; 4. When each group of rotating window sashes is closed and flush, fix the split cover plates to the outer surfaces of the large head halves of the corresponding vertical profiles of the window sashes with screws; 5. Use hidden cover plates to hide the screw heads.

[0007] The main beneficial effects of the utility model are:

[0008] (1) The large half of the vertical profile of the window sash adopts a split cover plate, which can make the connecting rod of each set of rotating window sashes easy and accurate to install, and ensure that each set of rotating window sashes is very flush when closed. In the previous design, the cover plate, window sash and the large half of the window sash profile are an integrated profile. The two ends of the cover plate need to cover the hinge seam to form a seal. Therefore, an end milling machine is required to mill off the parts of the two ends of the adjacent vertical profiles of the window sash, which wastes raw materials and labor time.

[0009] (2) The split cover can cover the joints of adjacent profiles for further sealing.

[0010] (3) Based on the principle that fast-flowing liquid or gas generates negative pressure on both sides, when strong winds pass through, the V-shaped sealing strip can further press the sealing surfaces of adjacent profiles to achieve better sealing. BRIEF DESCRIPTION OF THE DRAWINGS
