Abstract

The invention discloses a composite door. The composite door comprises an outer frame, an outer steel plate, an expanded perlite door core plate, a metal cellular board, an inner steel plate, a lock frame and an anti-theft lock, wherein the outer steel plate is fixedly installed on a frame of the outer frame through bolts, the expanded perlite door core plate is connected to the inner side of theouter steel plate through adhesive, the metal cellular board is fixedly connected to the frame of the outer frame through bolts, the inner steel plate at the inner side of the metal cellular board andthe outer steel plate are fixedly installed, and the anti-theft lock is installed on the lock frame. According to the composite door, structural improvement is conducted on the basis of an original anti-theft door, the structural strength of a door body is improved by means of the inner and outer steel plate design, the expanded perlite door core plate is good in heat resistance, the metal cellular board is welded with aluminum alloy and installed through the frame structure, the structural strength of the frame structure is improved by means of installation and design of staggered reinforcing ribs, the inner and outer steel plates and the expanded perlite door core plate are designed in a separating mode, which is beneficial for structurally refitting the anti-theft door in the later period.

Description

technical field [0001] The invention relates to the field of children's products, in particular to a composite door. Background technique [0002] The solid door is extruded from cold-rolled steel plates, and the door panels are all steel plates, the thickness of which is mostly 1.2 mm and 1.5 mm, which is strong in impact resistance. The double-layer steel plate of the door leaf is filled with rock wool thermal insulation and fireproof material, which has the functions of anti-theft, fire prevention, heat insulation and sound insulation. General solid anti-theft doors are equipped with peepholes, doorbells and other facilities. Most of the honeycomb panels used in existing anti-theft doors are made of paper, which has low structural strength and is easily deformed. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a composite door. [0004] To achieve the above object, the present invent...
