Thief-proof and fireproof door with lock protecting prying-resistant edge
The invention provides a thief-proof and fireproof door with a lock protecting prying-resistant edge and relates to a thief-proof and fireproof door. The fireproof doors in the prior art are unable to meet both the prying-resistant and fireproof requirements. The thief-proof and fireproof door is characterized in that a first stop part projecting outwards is arranged on the lock side of a door leaf, the back of the first stop part is parallel with the back of the door leaf, a forward lock protecting prying-resistant edge is formed on the first stop part, a first through hole is formed in the lock protecting prying-resistant edge, and the section of a door frame on a lock hole side is stepped and the door frame comprises a first longitudinal edge, a transverse edge, a second longitudinal edge, a second transverse edge and a second longitudinal edge, all of which are orderly connected together; the second longitudinal edge extends backwards to form a bolt limiting edge; a second through hole and a third through hole are formed in the bolt limiting edge and the third longitudinal edge, respectively; when the door is closed, the lock protecting prying-resistant edge of the door leaf is located in a groove formed between the bolt limiting edge and the third longitudinal edge. According to the thief-proof and fireproof door with the lock protecting prying-resistant edge, the door leaf and the door frame are tied into an effective integrated body, and therefore, the space for a prying tool to enter is reduced and the prying resistance of the thief-proof door is improved.
