Sealing rubber strip special for bolted window mullion linkage

Abstract

The utility model discloses a special sealing rubber strip for bolted window mullion linkage, and relates to the technical field of doors and windows for buildings. Each rubber strip is composed of an upper transverse edge, a vertical edge and a lower transverse edge, the shape of each rubber strip is matched with a gap of a guide rail, a plastic plate is bonded to the two lower transverse edges, two slopes are arranged on the two sides of the plastic plate and connected with the lower transverse edges, and a certain distance is reserved between the bottom face of the plastic plate and the bottom faces of the lower transverse edges. The thickness of the vertical edge is slightly smaller than a lower gap between the frame and the adapter block, and a groove is machined in the inner side of the vertical edge. The beneficial effects of the utility model are that the plastic plate is connected with the lower transverse edge of the rubber strip through the slope surfaces on the two sides, when the adapter block is connected with the frame through screws, the plastic plate presses the lower transverse edge downwards, the lower transverse edge moves towards the two sides, the lower end of the vertical edge is forced to rise and deform, and the lower gap between the frame and the adapter block is filled and sealed; meanwhile, the transverse positioning function is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows for buildings, in particular to a special sealing strip for connecting a screw-jointed window center support. Background Art

[0002] The door and window stiles are screwed together, which can effectively improve the connection strength of the joints. Figure 2 (As shown) The middle mullion is connected to the frame through an adapter block. The adapter block is first placed in the guide rail of the frame. After the adapter block is moved to the specified position, it is connected to the frame through screws, and then the middle mullion is connected to the adapter block. There must be upper and lower gaps between the window middle mullion and the adapter block in the horizontal part of the track. However, since the track is connected in a concave form, the gap cannot be completely sealed by injecting glue after construction, which leads to problems such as air leakage and whistling. There are problems such as unsightly appearance and pungent odor when in use. Utility Model Content

[0003] In order to solve the problem of gaps existing when screw-joined window stiles are installed, the utility model provides a special sealing rubber strip for connecting screw-joined window stiles.

[0004] The technical solution provided by the utility model is: a special sealing strip for a screw-connected window center support connection, comprising rubber strips on two sides, each rubber strip consisting of an upper horizontal edge, a vertical edge and a lower horizontal edge, the shape of the rubber strip conforms to the gap of the guide rail, a plastic plate is bonded to the two lower horizontal edges, two slope surfaces are opened on both sides of the plastic plate to connect with the lower horizontal edges, a distance is left between the bottom surface of the plastic plate and the bottom surface of the lower horizontal edge, the thickness of the vertical edge is slightly smaller than the lower gap between the frame and the adapter block, and a groove is processed on the inner side of the vertical edge.

[0005] The upper horizontal edge of the rubber strip is connected to a limit strip, and the thickness of the limit strip is slightly smaller than the upper gap between the frame and the adapter block.

[0006] The beneficial effects of the utility model are as follows: a plastic plate is arranged to connect the lower horizontal edge of the rubber strip through the sloped surfaces on both sides; when the adapter block is connected to the frame through screws, the plastic plate presses the lower horizontal edge downward, and the lower horizontal edge moves to both sides, forcing the lower end of the vertical edge to rise and deform, thereby filling and sealing the lower gap between the frame and the adapter block, and having a lateral positioning function.

[0011] like Figures 1 to 3 As shown, a special sealing strip for screwing the window center support link includes rubber strips 2 on both sides, each rubber strip 2 is composed of an upper horizontal edge 21, a vertical edge 22 and a lower horizontal edge 23, the shape of the rubber strip 2 conforms to the gap of the guide rail d, the two lower horizontal edges 23 are bonded with a plastic plate 1, two slope surfaces 5 are opened on both sides of the plastic plate 1 and connected to the lower horizontal edge 23, a distance is left between the bottom surface of the plastic plate 1 and the bottom surface of the lower horizontal edge 23, the thickness of the vertical edge 22 is slightly smaller than the lower gap e1 between the frame a and the adapter block c, which is convenient for assembly, and a groove 4 is processed on the inner side of the vertical edge 22 to accommodate the rubber deformation when the horizontal edge moves upward.

[0012] A plastic plate 1 is arranged to connect the lower horizontal edge 23 of the rubber strip 2 through the slope surfaces 5 on both sides. When the adapter block c is connected to the frame a through screws, the plastic plate 1 presses the lower horizontal edge 23 downward, and the lower horizontal edge 23 moves to both sides, forcing the lower end of the vertical edge 22 to rise and deform, thereby filling and sealing the lower gap e1 between the frame a and the adapter block c.

[0013] The upper horizontal edge 21 of the rubber strip 2 is connected to a limiting strip 3, the thickness of which is slightly smaller than the upper gap e2 between the frame a and the transfer block c. The limiting strip 3 is used for lateral limiting of the transfer block c and the middle stile b.
