Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, and specifically refers to a plastic door and window profile specially used for combining with old door and window frame materials. Background Art

[0002] The doors and windows of second-hand houses and old buildings that are more than ten or twenty years old generally use aluminum alloy, steel, plastic steel, or wooden frame materials, single or double-layer glass, which can meet the most basic requirements of wind load resistance, water tightness, air tightness, and sound insulation, but the thermal performance is generally poor (ordinary plastic steel windows are slightly better), because single aluminum or steel frame materials are good conductors of heat, and become a bridge for conducting indoor and outdoor temperature differences; single-layer or ordinary double-layer insulating glass also has poor thermal insulation performance. Old doors and windows lead to high air conditioning energy consumption, and it is difficult to avoid fogging and condensation on doors and windows due to the temperature difference between indoor and outdoor.

[0003] In the face of many drawbacks of old doors and windows, many renovation methods have emerged. The method commonly used in the market is to dismantle the original old doors and windows and replace them with ordinary insulated aluminum alloy doors and windows or higher-end system doors and windows. This renovation method undoubtedly has obvious performance improvements compared to the original old doors and windows, but there are also problems such as high price and complicated operation.

[0004] There is also a renovation plan that uses the original doors and windows and adds a new plastic door and window on the indoor side; however, under this renovation method, problems such as the new window profile structure being too large, waste of materials, and large space occupation arise.

[0005] Therefore, a special plastic door and window profile combined with old door and window frame materials has become an urgent problem to be solved. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a plastic door and window profile which has a small cross-sectional size and saves materials and is specially used for combining with old door and window frame materials.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a plastic door and window profile specially used for combining with old door and window frame materials, including a frame profile and a window sash profile; the frame profile includes an outer frame profile, a crossbar profile and a cover plate; the outer frame profile includes a fixing portion and a clamping block, a plurality of fixing plates are arranged on the outer side of the fixing portion, and the clamping block is arranged on the inner side of the fixing portion; the crossbar profile includes a supporting portion, an upper clamping block and a lower clamping block, and the upper clamping block and the lower clamping block are symmetrically arranged with respect to the supporting portion; the cover plate includes a plate body and buckles, and the buckles are arranged at both ends of the plate body;

[0008] The window sash profile comprises a window sash frame profile and an edge seal; one end of the window sash frame profile is provided with a glass fixing groove, and the other end is provided with a clamping groove; the edge seal is buckled on the outside of the window sash frame profile.

[0009] Furthermore, the cover plate includes a corner cover plate and a cross bar cover plate, the corner cover plate is buckled at the corner joint of the window frame, and the cross bar cover plate is buckled at the joint between the window frame and the cross bar.

[0010] Furthermore, the window sash frame profile includes an edge profile and a middle profile, the edge profile is the upper and lower frames and the left and right wall frames of the window sash, and the middle profile is the left and right overlapping frames in the middle of the window sash.

[0011] The advantages of the present invention compared with the prior art are: since the present invention is attached to old door and window frame materials, it does not need to have the ability to bear the load alone like ordinary plastic steel doors and windows, because the combined frame materials mainly rely on the original door and window frame materials to bear vertical and horizontal loads; therefore, under the premise of meeting the structural requirements, the cross-sectional size is reduced as much as possible, while saving materials, it is also more compact and delicate, reducing the occupation of the original window sill space.
