Overspeed locking security door

Abstract

The invention discloses an overspeed locking security door, which comprises a door lock handle, a door lock, a counter lock switch, a door body, a slide block, an electronic lock, a metal guide rail,an insertion hole, a control module, a casing, an acceleration sensor, a fixing seat, a connecting rod, a timing module and a door frame, wherein the door body is arranged in the door frame; one sideof the door body is connected with the door frame through a hinge; and the door lock is arranged at the other side of the door body. The acceleration of the door body is sensed by the acceleration sensor; when the acceleration of the door body is greater than 1.5g, the value shows that the door opening and closing speed is too high, and meanwhile, the door collision condition possibly exists; at the moment, the control module receives a signal sent by the acceleration sensor so as to control the electronic lock to work; therefore a lock bolt is timely inserted into the insertion hole for locking the door body; the collision due to too high speed is prevented; meanwhile, the door is protected; the potential safety hazards due to external door collision can also be avoided; and people can take response measures in time.

Description

technical field [0001] The invention relates to an anti-theft door, in particular to an overspeed locking anti-theft door. Background technique [0002] The full name of anti-theft door is "anti-theft safety door". It has both anti-theft and safety performance. 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 hole can be opened on the door leaf. opening, or a 38 mm2 opening within a semicircle of 150 mm2 at the locking point. And the lock used on the security door must be the special lock for the security door with anti-drilling function after passing the test by the Testing Center of the Ministry of Public Security. [0003] After the anti-theft door is opened, when the acceleration is too large and used for a long time, it is easy ...

Problems solved by technology

[0003] After the anti-theft door is opened, when the acceleration is too high and used for a long time, it is easy to cause damage to the door body. At the same time, if the door is opened and closed too quickly, the noise will be very loud in the event of a collision. At the same time, criminals will induce indoor personnel to unlock it.
