Prying-resistant door

Abstract

The invention discloses a prying-resistant door which comprises a door frame, a door leaf and a lockset, a lock side door leaf is provided with the lockset with a spring bolt and an inclined bolt, a hinge side door leaf is hinged to a hinge side door frame through a hinge, the outer door face of the lock side door leaf extends to form a protective cover plate, and a sealing strip is arranged in the protective cover plate. The first anti-prying steel abuts against the sealing strip and is fixedly connected to the side face of the lock side door leaf through a bolt, the second anti-prying steel is fixedly connected with the child door leaf or the lock side door frame through a bolt, and the first anti-prying steel and the second anti-prying steel are provided with penetrating holes matched with the spring bolt and the inclined bolt and bolt receding holes. When the anti-prying door is in a locked state, the second anti-prying steel is located between the first anti-prying steel and the lock side door leaf. When the anti-prying door is pried violently, the anti-prying steel on the door frame side is closer to the door leaf on the locking side, locking is tighter, the opening difficulty of the anti-prying door is increased, and the anti-prying door has great commercial value.

Description

Technical field [0001] The present invention relates to the field of door technology, in particular to a kind of anti-pry door. Background [0002] With the development of society, people have higher requirements for the safety of the portal, many production enterprises or individuals have studied the anti-pry door, and the structure of the door frame and the door leaf has been improved to varying degrees, but some of the anti-pry doors that appear on the market are not designed reasonably, the anti-pry performance is not strong, and the criminals use tools such as crowbars to insert between the door frame and the door leaf, and can forcibly pry open the anti-theft door through violent disassembly; the other part of the anti-pry door has a strong anti-pry performance, but due to its complex structure, the manufacturing and installation costs are high. Does not meet the needs of the market. For example, the patent no. 201721274909.1 discloses a metal anti-pry door, by setting an L...

AI Technical Summary

Problems solved by technology

[0002] With the development of society, people have higher requirements for the security of doors. Many manufacturers or individuals have conducted research on tamper-resistant doors, and have improved the structure of door frames and door leaves to varying degrees. Part of the prying door is unreasonably designed and the anti-prying performance is not strong. Criminals use crowbars and other tools to insert between the door frame and the door leaf, and the anti-theft door can be forcibly pried open through violent disassembly; the other part of the anti-prying door has strong anti-prying performance, but due to its complex structure, high manufacturing and installation costs, it does not meet the needs of the market

For example, the patent application No. 201721274909.1 discloses a metal pick-resistant door, by setting an L-shaped steel plate on the door frame corresponding to the lock tongue, and at the same time setting an annular guide groove at the lock tongue position of the door plate, and setting a protective tube in the annular guide groove When criminals use violence to insert tools such as a crowbar into the gap between the door panel and the L-shaped steel plate, since the crowbar cannot directly act on the lock tongue, it is difficult to make the lock tongue escape from the door frame, which improves the security of the door. The anti-pry performance of the metal anti-pry door, but this kind of anti-pry device can only protect the position of the lock tongue, and the structure is relatively complicated, and it is also prone to failures such as jamming during use

[0003] Because the existing anti-prying doors cannot meet people's needs, thieves often burglary through prying doors, which seriously threatens the safety of people and property and seriously affects social stability and order.
