Multifunctional security door

Abstract

The invention discloses a multifunctional security door. The multifunctional security door structurally comprises a door frame, a door body, a contact piece and a door lock, the door body is clamped to the inner side of the door frame, the door lock is installed in the middle part of the door body, the door body comprises a water pipe, a control switch, an iron piece and a smoke stopping device; the control switch comprises a sliding groove, a baffle plate, a piston cavity, a piston rod and a connecting rod; the smoke stopping device comprises a water storage tank, a connecting pipe and a water spraying hole; and the water spraying hole is composed of a fixed block, an outer spray pipe and an inner sprayer. According to the multifunctional security door, when water flows through the outerspray pipe, the water flow is guided by a guide block, then the water flow is blocked by bumps which are arranged in a staggered mode to generate bubbles, so as to improve the interception effect of water spraying, then the water flow is sprayed in a circular shape through the cone-shaped inner sprayer, finally a small part of the water flow is sprayed vertically downward through a flow groove, sothat the water can cover the whole door gap to avoid smoke floating to another space through the door gap, causing the personnel in the another space to inhale the smoke and have poor breathing.

Description

technical field [0001] The invention relates to the security field, in particular to a multifunctional security door. Background technique [0002] Security door refers to a device that can be opened and closed at the entrance and exit of a building. Generally speaking, it can be divided into anti-theft doors, fire doors, etc. Fire doors generally have the function of isolating the fire, isolating the fire in one space and preventing the fire from spreading to another space. . [0003] Based on the above inventors' discovery, the existing multifunctional security door mainly has the following disadvantages, such as: in the event of a fire, a large amount of thick smoke will be generated when the burning material burns, because there is a gap between the security door and the ground. There is a certain gap, so the smoke will pass through the gap between the security door and the ground to another space, causing people in another space to inhale the smoke and have difficulty ...
