Energy-saving push-pull type door/window leaf

Abstract

The invention discloses an energy-saving push-pull type door / window leaf which comprises a track and a push-pull type door / window leaf, wherein the track is mounted in a window frame; the push-pull type door / window leaf slides along the track; the push-pull type door / window leaf comprises a frame and a piece of glass embedded into the frame; flexible stuffing glue is arranged at the top and the bottom of the frame; the flexible stuffing glue is connected with a locking operation part of the door / window leaf through a linking mechanism; when moving, the door / window leaf is not locked by the locking operation part, meanwhile the sealing effect of the flexible stuffing glue is not brought into play, then a user can easily move the door / window leaf; when the door / window leaf is closed and is fixed with the window frame through the locking operation part, the linking mechanism is driven by the locking operation part to enable the flexible stuffing glue to extrude to a seam between the frame and the window frame and stuff the seam, so that seal can be effectively formed on the tops and at the bottoms of the door / window leaf and the window frame, air tightness between the door / window leaf and the window frame can be improved, circulation flow of hot and cold air can be effectively prevented, and the energy-saving effect can be improved.

Description

technical field [0001] The invention relates to an energy-saving structure of a push-pull door and window fan. Background technique [0002] Ministry of Construction Announcement No. 659 "Construction Industry "Eleventh Five-Year" Promotion and Application and Restriction and Prohibited Technology (First Batch) Announcement" "Building Door and Window Energy Saving Technology" stipulates that "houses with heat-insulating aluminum profile hollow glass casement windows Buildings, in which casement windows are only suitable for multi-storey buildings", the use of casement windows is limited; the airtightness of sliding windows is insufficient, and sunshade louvers are often installed indoors, and the energy-saving effect is not good; generally speaking, hollow The effective life of glass is 8 to 10 years (during its use, there may be water vapor infiltration and water drops), and the popularity rate of use is not high. Therefore, the window has become the weakest link in the en...

AI Technical Summary

Problems solved by technology

1. Heat convection: hot and cold air circulates through the gaps between doors and windows, and heat is exchanged through gas convection, resulting in heat loss; 2. Heat conduction: heat generated by the molecular movement of the materials used in doors and windows Transfer, through one surface of the material itself to the other, resulting in heat loss; 3. Heat radiation: it is directly transmitted in the form of rays, resulting in energy loss

Due to the poor sealing between the doors and windows of the existing doors and windows, it is easy to form hot and cold air circulation, which makes the energy saving effect not good
