T-shaped door with groove-shaped cover port

Abstract

The invention discloses a T-shaped door with a groove-shaped cover port. The T-shaped door comprises a door frame component and a door leaf component, the door frame component mainly comprises a hinge side frame, a lock side frame, an upper frame, a lower frame and a door frame sealing strip, and the door leaf component mainly comprises an outer door plate, an inner door plate and a filler. Each of the hinge side frame, the lock side frame and the upper frame of a door frame is provided with two proscenium openings 1 and 2, the proscenium opening 1 at a position where the door frame and a door leaf are overlapped connection is designed with outwards-raised prying-resistant ribs, and the door frame sealing strip is arranged at the proscenium opening 2 of the door frame. A T-shaped cover port of the door leaf is designed with prying-resistant edges raised oppositely to the prying-resistant ribs of the door frame, and a structure with fan-frame cover ports in toothed connection matched with overlapped connection to improve airtight performance of the T-shaped cover port. The door leaf component comprises an outer door plate, an inner door plate, a filler and an outer door plate wrapping edge, the outer door plate wrapping edge comprises an F-shaped section wrapping edge, a door leaf sealing strip and a wrapping edge connecting corner piece, the F-shaped section wrapping edge is designed with prying-resistant edges forming the groove-shaped cover port of the door leaf, the wrapping edge component is connected with a T-shaped cover edge of the door leaf through screws to form a groove-shaped T-shaped cover port of the door leaf, and the door leaf sealing strip is arranged at the groove-shaped T-shaped cover port of the door leaf. The F-shaped section wrapping edge of the door leaf is added to enhance a rectangular T-shaped cover edge of the door leaf, so that a rectangular T-shaped cover edge of a common steel T-shaped door leaf is firm and attractive in appearance. In addition, a T-shaped edge of the groove-shaped cover port with frame-fan toothed fit can greatly improve soundproof and heatproof performance of the door.

Description

[0001] (1) Technical field: [0002] The patent of the present invention relates to an anti-theft safety door structure, which belongs to safety prevention products. [0003] (2) Technical background: [0004] The edge of the T-shaped door is named after the shape of the letter T. It originated in Germany and can also be called a German-style door. T-shaped doors have the characteristics of strong sound insulation, heat preservation, sealing, impact resistance and environmental protection. They are widely used in interior doors in Europe, and later on entrance doors. Most of the European entrance doors are inward-opening doors, which do not require high T-shaped edge security performance, while in China, the external-opening door structure is the main structure. In China, steel T-shaped doors are still in their infancy. Although the T-shaped door has many advantages, for the outward-opening steel T-shaped door, the rectangular T-shaped cover edge of the outer door panel is re...
