Armored door leaf structure

Abstract

The invention discloses an armored door leaf structure. The armored door leaf structure consists of a door core, a decorative outer door plate, an outer door plate decorative covered edge, a screw A, a door leaf sealing strip, a decorative inner door plate, a screw B and an inner door plate covered edge. A whole covered edge of a door leaf is divided into a split structure of the outer door plate decorative covered edge and the inner door plate covered edge, therefore, the problem of 45-degree chamfer angles of four corners of inner and outer door plates of the door leaf is solved. External covered edge fixing screws are all designed to be in a built-in fixing screw mode so as to improve the attractiveness of the side edge of the door leaf. A clamping groove A, a clamping groove B and a C-shaped clamping groove C are designed on the outer door plate decorative covered edge, the clamping groove B is clamped with the side edge of the decorative outer door plate, the clamping groove A and a door core outer extending lug edge are in clamped connected and fixed through the screw A, the door leaf sealing strip is clamped in the C-shaped clamping groove C of the outer door plate decorative covered edge, prying resistance and airtightness of t-shaped cover edge of the door leaf are greatly enhanced, and the door leaf is not prone to being pried. The inner door plate covered edge is arranged on the periphery of the decorative inner door plate, a clamping groove and an abutting head are arranged on the inner door plate covered edge, the clamping groove is connected to the side edge of the decorative inner door plate in a clamped mode, and the abutting head abuts against the bent outer corner A of the side edge of a profile of a door core frame; and the decorative inner door plate and the inner door plate covered edge are fixed to the door core frame by the screw B from the inner side of the profile on the periphery of the door core frame to the outer side, and thus a double-step door leaf structure is formed.

Description

Technical field: [0001] The patent of the invention relates to a door leaf structure of an armored safety door, which belongs to a safety protection product. [0002] technical background: [0003] Armored doors originated from Italy and Germany. Generally, the T-shaped door leaf structure with a step is called T-shaped door, and it can also be called 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. At present, although steel T-shaped doors have many advantages in China, for outward opening safety doors, the rectangular T-shaped cover edge of the outer door panel is relatively thin, and the...
