Prying-resistant anti-bursting type security door with adjustable guiding device

Abstract

The invention discloses a prying-resistant anti-bursting type security door with an adjustable guiding device. Defects exist in prying-resistant anti-bursting functions of an existing security door, and a door leaf is prone to loosening after being closed. The prying-resistant anti-bursting type security door includes the door leaf, door frames, a door leaf prying-resistant steel part, a door frame prying-resistant steel part, an anti-bursting mechanism and the guiding device. The door frames include the upper door frame, the hinged side door frame and the locking side door frame; the door leaf prying-resistant steel part includes an outer clamping plate, a transition plate, a U-shaped prying-resistant plate and an inner clamping plate, wherein the outer clamping plate, the transition plate, the U-shaped prying-resistant plate and the inner clamping plate are integrally formed, and the door frame prying-resistant steel part includes a door frame prying-resistant plate. The guiding device includes a support and pin rollers, the anti-bursting mechanism includes an overturning pulling buckle assembly, a separation-reunion insert column and a lifting drive assembly, and the overturningpulling buckle assembly includes a fixed slice and an overturning slice. According to the prying-resistant anti-bursting type security door, intensity of assembly of the door leaf pry-resistant steelpart is high, the prying-resistant effect is good, the door leaf of the security door can only open by an opening that staff cannot pass, and thus the situation that the staff outside the door forcibly burst into the door is avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-theft doors, and in particular relates to an anti-prying and anti-breaking type anti-theft door with an adjustable guide device. Background technique [0002] Anti-theft door, the full name of anti-theft safety door, has both anti-theft and safety performance, and can be made of different materials. The use of anti-theft doors greatly increases the security of property. The anti-theft door is equipped with an anti-theft lock, which can resist abnormal opening under certain conditions within a certain period of time. It has certain safety protection performance and meets the corresponding anti-theft safety level. According to the "General Technical Conditions for Anti-theft Safety Doors", a qualified anti-theft door cannot be pried open by ordinary hand tools such as chisels, screwdrivers, crowbars, and portable electric tools such as electric hand drills within 15 minutes or a 615 square millimeter ...

AI Technical Summary

Problems solved by technology

In fact, the strength of each of the above parts is not very ideal, and cannot effectively prevent outsiders from intruding

[0005] During the use of the anti-theft door, it is prone to the problem that the door leaf can still be turned over in a small range after closing

This is generally caused by insufficient matching precision between the door leaf and the door frame, improper installation, wear or deformation caused by long-term use, etc.

This kind of door that is still loose after closing is less safe, and it will generate noise under the action of wind

In addition, the deadbolt of the existing fastened door is in contact with the guide piece of the door frame. During use, the friction force between the deadbolt and the guide piece of the doorframe will hinder the convenience of opening the door and even generate noise.

Moreover, long-term friction is prone to wear on the lock tongue and door frame guide
