Fire lock and escape function two-in-one box

Abstract

This utility model proposes a dual-function enclosure for fire protection and elevator locking. The enclosure includes a back panel, an outer shell liner, and an outer shell. The outer shell liner and outer shell are assembled to form a shell structure. The back panel is fixed to a surface adjacent to the control cabinet, and the shell structure is fixedly connected to the back panel. A fire switch and an elevator locking switch are installed within the shell structure. The fire switch communicates with the fire protection system. Both the fire switch and the elevator locking switch have lead-out wires, which are combined into a single cable bundle and connected to an adapter plug. The adapter plug connects to a cable and communicates with the elevator control system. The signals from both switches are led out through wires, bundled together, and connected to the adapter plug. The cable is then connected to the elevator control system via the adapter plug, realizing the elevator's fire protection and elevator locking functions.

Description

Technical Field

[0001] This utility model relates to an improvement of an elevator emergency function device, specifically a box that combines fire-fighting and elevator locking functions. Background Technology

[0002] The fire-fighting function of an elevator is to stop the elevator car at the fire station and lock the doors after receiving a fire signal when a fire occurs. The purpose is to protect and evacuate passengers in a timely manner. The elevator locking function is to stop the elevator car at the maintenance station when the elevator needs to be inspected or otherwise needs to be stopped, so as to facilitate elevator maintenance and other work. Traditionally, these two functions require different devices and signals to enable the elevator to perform the corresponding functions. The signals emitted by these two systems may be mismatched with the passive signals required by the elevator control system, so improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a box that combines fire-fighting ladder locking function.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The housing includes a back panel, an outer shell liner, and an outer shell. The outer shell liner and the outer shell are assembled to form a shell structure. The back panel is fixed to the surface adjacent to the control cabinet. The shell structure is fixedly connected to the back panel. A fire switch and a ladder lock switch are installed in the shell structure. The fire switch is communicatively connected to the fire protection system. Both the fire switch and the ladder lock switch have connecting wires. The connecting wires of the two are combined into a single wire bundle and connected to an adapter plug. The adapter plug connects to a cable and is communicatively connected to the elevator control system. The main structure of the housing is formed by the outer shell liner and the outer shell, in which the fire switch and the ladder lock switch are installed. The ladder lock switch is a key switch used for inspection and maintenance. The fire switch is connected to the fire protection system. The signal from the fire protection system can be received and transferred by the fire switch. The signals from both are led out through wires and bundled into a single bundle, connected to an adapter plug. The cable is connected through the adapter plug to the elevator control system, realizing the fire protection and ladder lock functions of the elevator.

[0005] Furthermore, the adapter plug includes at least four pins. Pins 1 and 2 are connected to the elevator lock switch and the elevator lock control circuit of the control system. Pins 3 and 4 are connected to the guide switch and the fire control circuit of the control system. By defining the pins of the two types of wires and fixing them at specific positions on the adapter plug, and through the orientation and positioning of the plug, they are connected to the corresponding transmission signal lines in the cable. This achieves centralized and transfer signal connection, allowing both functions to be integrated into one housing. This enables rapid operation of different functions in the same location, facilitates daily maintenance and repair, saves structural space, and improves work efficiency.

[0006] Furthermore, the end of the cable is positioned opposite the adapter plug and has a corresponding connector with a mating socket. The adapter plug and the mating socket are mated together to establish a communication connection. The cable has a mating socket corresponding to the adapter plug, facilitating mating, preventing incorrect wiring, and ensuring reliable functionality.

[0007] Furthermore, the fire switch has a push-to-trigger structure, and the housing is made of transparent material, making the trigger structure of the fire switch visible from the outside of the housing structure. The fire switch also has a manual triggering function, allowing for emergency triggering, and it can be directly observed from the outside, enabling rapid activation in emergency situations.

[0008] Furthermore, the back panel is formed by pressing sheet metal and has a flat panel body, wiring holes, mounting holes, and fixing clips. The flat panel body is the basic planar structure, and the wiring holes and mounting holes are formed on the flat panel body. Fixing clips are set on the edge of the flat panel body, and the fixing clips clamp the shell structure. The back panel is fixed to its mounting position through the mounting holes. The back panel has a stable fixing function, can be fixed on a suitable surface, allows for orderly arrangement of wiring, is easy to install, and facilitates wiring and subsequent maintenance.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is a box-type device that combines fire protection function and elevator locking function. It is used in conjunction with elevator operation, saves structural space, and has a short start-up time, meeting the needs of emergency response and improving elevator safety.
