Description

Technical Field

[0001] This invention relates to a quick-release escape lock nose for a marine weatherproof steel door. Background Technology

[0002] Ships are a general term for vehicles that can navigate or anchor in rivers, lakes, and seas for transportation or operations. According to regulations, all external doors must be secured to prevent unauthorized or irrelevant personnel from entering. Therefore, padlocks are typically used to lock these doors from the outside. To prevent unauthorized personnel or pirates from boarding and completely locking passengers inside the cabin, or to address other emergency situations requiring rapid escape, steel doors with padlocks are required to be equipped with an escape lock that can be opened from the inside – this is called an escape lock. A typical escape lock consists of a wing nut and a stud welded together. When facing an externally padlocked steel door and needing to escape, the wing nut is unscrewed, releasing the lock and allowing the door to be pushed open. However, current escape lock designs require the wing nut to be fully unscrewed to release the stud for escape. Considering the high stress and time constraints of an emergency, where operator error could affect the optimal escape time, a faster escape lock device is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a marine weatherproof steel door quick-release escape lock nose that enables rapid release of the escape lock nose.

[0004] The technical solution adopted by the present invention to achieve the above objectives is: a quick-release escape lock nose for a marine weatherproof steel door, including a stud (1), a wing nut (2), a limiting block (3), an eye ring (4), an eye ring base (5), an eye plate (6), a steel cabin wall (7), a steel door frame (8), and a steel door leaf (9). The eye plate (6) is fixed together with the steel door leaf (9). After the eye ring (4) is fixed to the eye ring base (5), the stud (1) is fixed at the center of the eye ring base (5). The combination of the eye ring (4), the eye ring base (5), and the stud (1) passes through the steel cabin wall (7) and the steel door frame (8). The limiting block (3) is fixed to the steel door frame (8) along with the eye ring base (5).

[0005] The stud (1) and the wing nut (2) adopt an alternating threaded section and a wedge section structure, respectively. The depth of the wedge section ensures that the threaded section can pass through directly. There is a 5° gap between each threaded section and the wedge section.

[0006] The stud (1) and the wing nut (2) each have three wedges.

[0007] The threaded part of the wing nut with three wedges passes directly through the bottom of the stud with three wedges and is close to the steel cabin wall (7) to lock the wing nut (2).

[0008] A spring washer is provided between the steel cabin wall (7) and the wing nut (2).

[0009] This invention relates to a marine weatherproof steel door quick-release escape lock nose, which solves the safety hazard of personnel making mistakes in operation during escape situations with high tension and time constraints, thus affecting the optimal escape time.

[0018] like Figures 1 to 8As shown, the marine weatherproof steel door quick-release escape lock nose includes a stud 1, a wing nut 2, a limiting block 3, an eye ring 4, an eye ring base 5, an eye plate 6, a steel cabin bulkhead 7, a steel door frame 8, and a steel door leaf 9. The eye plate 6 is fixed to the steel door leaf 9. After the eye ring 4 is fixed to the eye ring base 5, the stud 1 is fixed at the center of the eye ring base 5. The assembly of the eye ring 4, eye ring base 5, and stud 1 is passed through the steel cabin bulkhead 7 and the steel door frame 8. The limiting block 3 is placed against the bottom of the eye ring. The seat 5 is fixed to the steel door frame 8. The stud 1 and the wing nut 2 adopt alternating threaded and wedge-shaped structures, respectively. The depth of the wedge ensures that the threaded part can pass directly through. The thread and the wedge are each about 55°, and there is a 5° gap between each threaded part and the wedge to prevent seizing due to machining problems. There are 3 wedges on the stud 1 and the wing nut 2. The threaded part of the wing nut with 3 wedges passes directly through the bottom of the stud with 3 wedges, close to the steel frame. The cabin bulkhead 7 directly locks the wing nut 2. To achieve a better locking effect, a spring washer can be provided between the steel cabin bulkhead 7 and the wing nut 2. A wedge-shaped opening is made for the stud and the wing nut, so that they can quickly reach the locking position and directly align and lock the threads. Alternatively, the thread of the wing nut can be directly inserted into the wedge of the stud in the locking position to directly release the stud on the eye plate base. To prevent the eye ring and the eye ring base from rotating due to external force, which would cause the wing nut and the stud welded to the eye ring base to fail to lock, the eye ring base should be rectangular, with a limit block welded on one side to prevent failure due to movement. Since both the wing nut and the stud have wedge openings, the wing nut can directly reach the locking position through the wedge opening without having to complete the entire thread travel. The working principle of this invention is to change the usual form of wing nuts and studs needing to go through the entire thread travel to tighten by opening a wedge opening, so that the nut can reach the bottom of the stud and lock directly.
