Abstract
Description
Technical Field
[0001] This utility model relates to an escape safety door for use in clean areas, and more particularly to an integrated evacuation safety door. Background Technology
[0002] At the boundary between clean and non-clean areas in the factory, evacuation safety doors, which are not normally opened, are installed as required for safe escape. Conventional tempered glass evacuation safety doors are typically opened by breaking the glass with a fire hammer during an escape attempt. However, using a fire hammer to strike tempered glass doors sometimes fails to break the glass quickly enough, delaying evacuation time and increasing the risk of people slipping on broken glass and sustaining secondary injuries.
[0003] There is a type of safety door that can be opened to quickly evacuate personnel and prevent injuries from broken glass. However, because the door can be opened, it is inevitable that people will enter and exit through this door, causing contamination of the cleanroom. In addition, there are many components on the door that are exposed on the door surface. Dust accumulates on these components and is not easy to remove. Over time, the dust will be re-entrained by airflow and contaminate the cleanroom.
[0004] Another type of evacuation safety door uses a separate top and bottom locking mechanism to ensure closure. However, the effectiveness of these mechanisms deteriorates under prolonged positive pressure within the cleanroom, widening the door gaps and causing changes in the pressure difference between the inside and outside of the cleanroom, thus affecting the maintenance of cleanroom cleanliness. There is also a type of safety door with a separate magnetic lock. This type has two drawbacks: First, the magnetic lock protrudes from the surface where the door leaf and frame meet, increasing the gap between them. This larger gap increases the amount of sealing material needed and makes sealing the safety door more difficult. Second, the large gap exposes a significant area of the sealant between the door leaf and frame, making it prone to oxidation and failure over time, leading to a poorer seal and further reducing the cleanroom's cleanliness. Utility Model Content
[0005] The purpose of this utility model is to solve the common drawbacks of existing evacuation safety doors and provide an integrated evacuation safety door that cannot be opened arbitrarily and opens smoothly, facilitating personnel evacuation. The magnetic lock device (with signal output and buzzer, voice and light alarm functions) and the door closer are hidden in the door frame and door leaf structure. The gap between the door frame and the door leaf is small, which can save sealing materials and has a good sealing effect, thus ensuring the cleanliness of the clean area.
[0006] The purpose of this utility model can be achieved. This utility model's integrated evacuation safety door includes power supply and signal lines connecting a magnetic lock device, a steel door frame, a steel door leaf with an observation window, hinges connecting the door leaf and the door frame, a fire escape lock, and a concealed door closer. The feature of this utility model's integrated evacuation safety door is that: a magnetic lock mounting groove is horizontally provided on the top door stop of the steel door frame, which is perpendicular to the door leaf surface at the end away from the hinge; a transition steel plate is fixed around the magnetic lock mounting groove; the magnetic lock device is internally installed and fixed in the magnetic lock mounting groove through the transition steel plate and screws; on the top of the steel door leaf, at the end away from the hinge, a steel plate mounting groove is horizontally provided parallel to the door leaf surface, corresponding to the magnetic lock mounting groove on the steel door frame; an adsorption steel plate is fixed in the steel plate mounting groove by fixing bolts; the adsorption steel plate is either attracted to or separated from the magnetic lock device.
[0007] This utility model relates to an integrated evacuation safety door, wherein a magnetic lock device is installed on the steel door frame and an adsorption steel plate is installed on the steel door leaf; a fire escape lock is installed on the steel door frame and the steel door leaf; a concealed door closer is installed on the steel door frame and the steel door leaf to form a safety door locking structure, wherein the magnetic lock device and the adsorption steel plate are in an attracted state; the fire escape lock is in a locked state on the steel door leaf; and the concealed door closer is in a closed state, and the three together lock the integrated evacuation safety door.
[0008] This utility model integrates an evacuation safety door, wherein the magnetic lock mounting groove is strip-shaped, and the outer surface of the magnetic lock device installed in the magnetic lock mounting groove is flush with the top door stop surface of the steel door frame; the steel plate mounting groove is strip-shaped, and the outer surface of the adsorption steel plate installed in the strip-shaped steel plate mounting groove is basically flush with the upper outer surface of the steel door leaf.
[0009] This utility model is an integrated evacuation safety door, wherein a rubber adjusting pad is provided between the bottom surface of the adsorption steel plate and the bottom surface of the steel plate mounting groove.
[0010] This utility model integrates an evacuation safety door, wherein the fire escape lock is installed on the left side of the steel door leaf, 1000mm from the ground. The fire escape lock device is made of 1.2mm thick stainless steel plate, the lock tongue is a 304 stainless steel casting, the pressure bar is 400mm long, the cross section is rectangular, and the surface finish is Ra2.5.
[0011] The difference between this integrated evacuation safety door and existing technologies lies in the fact that the steel door frame of this integrated evacuation safety door has a magnetic lock mounting groove on the top door stop, with a fixed adapter steel plate around it. A magnetic lock device is installed within the groove through the adapter steel plate. The top of the steel door leaf corresponds to the magnetic lock mounting groove on the steel door frame, with a groove for fixing an adsorption steel plate. The magnetic lock device, horizontal fire escape lock, and concealed door closer installed on the steel door frame and door leaf together form the safety door locking structure. When the magnetic lock device is engaged with the adsorption steel plate; the fire escape lock is locked on the steel door leaf; and the concealed door closer is closed, all three components work together to lock the integrated evacuation safety door. This integrated evacuation safety door opens smoothly, facilitating personnel evacuation. The components are concealed, the gap between the door frame and door leaf is small, saving sealing materials and maintaining a good cleanliness level in cleanrooms. The magnetic lock device (with signal output and buzzer, voice, and light alarm functions) automatically unlocks in case of fire, pressing down the fire escape lock pressure plate, allowing for safe evacuation.
