Description

Technical Field

[0001] This utility model belongs to the field of emergency assistance technology, and in particular relates to a fiber optic emergency telephone broadcasting device. Background Technology

[0002] Emergency telephone broadcasting systems typically include components such as emergency telephones, broadcasting equipment, and alarm devices. In traditional systems, telephone equipment can be damaged or stolen by criminals, causing system failure and preventing emergency calls and broadcasts from being executed. Therefore, it is necessary to incorporate anti-theft technologies to enhance equipment protection and ensure its proper functioning in critical moments.

[0003] According to a public announcement (publication number: CN 213547692U), a visual emergency telephone broadcasting device for highway tunnels includes a housing, a help terminal, an amplifier, a first speaker, a first microphone, a smart dehumidifier, a drain pipe, a camera, and a first help button, all installed inside the housing. The bottom of the housing has a through hole through which the drain pipe passes and connects to the outlet of the smart dehumidifier. The housing includes a front cover, a rear compartment connected to the front cover, and a sealing strip between the rear compartment and the front cover.

[0004] In the aforementioned application, the cooperation between the box and the emergency call terminal component makes it difficult to lock the phone box and issue an alarm when it is stolen, leading to the theft of the phone box by dangerous individuals. Therefore, we propose a fiber optic emergency telephone broadcasting device. Utility Model Content

[0005] The purpose of this invention is to provide a fiber optic emergency telephone broadcasting device. Through the coordinated operation of components such as the threaded rod, spring telescopic rod, and alarm bell in the locking mechanism, when the telephone box is closed after use, if a dangerous person attempts to steal the telephone box and the staff dares not approach, the staff can activate the motor. This causes the threaded rod to move into the locking groove, locking the door. Simultaneously, the moving sleeve pushes the force-bearing rod, causing the telescopic end of the spring telescopic rod to extend outward, driving the push rod to press against the force-bearing inclined block, activating the alarm bell. At the same time, the alarm is broadcast through the broadcast communication line inside the duty room. This design effectively locks the door, preventing the theft of the emergency telephone inside the telephone box and solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a fiber optic emergency telephone broadcasting device, including a telephone box, a broadcast communication cable on the top of the telephone box, an emergency telephone inside the telephone box, and a locking mechanism inside the telephone box;

[0008] The locking mechanism includes a locking door and a motor. The side of the locking door is rotatably connected to the side of the telephone box. A mounting box is fixedly connected to the side of the locking door. A threaded rod is threadedly connected to the side of the mounting box. One end of the threaded rod is fixedly connected to the output shaft of the motor. A locking groove is provided on the inner wall of the telephone box. A movable sleeve is fixedly connected to the circumferential surface of the threaded rod. A spring telescopic rod is fixedly connected to the side of the mounting box.

[0009] Furthermore, a force-bearing rod is fixedly connected to the telescopic end of the spring telescopic rod, and a push rod is fixedly connected to the telescopic end of the spring telescopic rod. An alarm bell is provided on the side of the locking door, and a turning button is provided on the side of the alarm bell.

[0010] Furthermore, a force-bearing inclined block is fixedly connected to the circumferential surface of the turning button, and a return spring is fixedly connected to the side of the force-bearing inclined block. The end of the return spring away from the side of the force-bearing inclined block is fixedly connected to the circumferential surface of the turning button. The purpose is to reset the force-bearing inclined block when it is not under force.

[0011] Furthermore, the side of the force-bearing rod is located on the displacement trajectory of the movable sleeve, and the side of the force-bearing inclined block is located on the displacement trajectory of the push rod. The purpose of this is to ensure that the movement of the movable sleeve pushes the force-bearing rod to move, thereby driving the push rod to push the force-bearing inclined block.

[0012] Furthermore, the telephone box is equipped with a ventilation mechanism, which includes a pressure rod. One end of the pressure rod is fixedly connected to the side of the locking door. A protective plate is slidably connected to the side of the emergency telephone. A support shaft is rotatably connected to the side of the protective plate. A rotating plate is fixedly connected to the circumferential surface of the support shaft. A support plate is fixedly connected to the inner wall of the telephone box. A tension spring is fixedly connected to the bottom of the support plate. The end of the tension spring away from the bottom of the support plate is fixedly connected to the top of the protective plate. The function of the ventilation mechanism is to allow the emergency telephone to ventilate daily, preventing the emergency telephone from getting damp and damaged.

[0013] Furthermore, a torsion spring is fixedly connected to the side of the protective plate, and the end of the torsion spring away from the side of the protective plate is fixedly connected to the circumferential surface of the support shaft. The function of the torsion spring is to reset the plate when it is not under force.

[0014] Furthermore, the top of the protective plate is elastically connected to the bottom of the support plate via a tension spring, and the side of the support plate is elastically connected to the side of the protective plate via a torsion spring, the purpose of which is to reduce human intervention.

[0015] Furthermore, the side of the rotating plate is located on the displacement trajectory of the pressure rod, the purpose of which is to ensure that the movement of the pressure rod can press the rotating plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model utilizes the interplay between components such as the threaded rod, spring telescopic rod, and alarm bell in the locking mechanism. When the telephone box is closed after use, if a dangerous person attempts to steal the telephone box and the staff dares not approach, the staff can activate the motor. This causes the threaded rod to move into the locking groove and lock the door. Simultaneously, the moving sleeve pushes the force-bearing rod, causing the telescopic end of the spring telescopic rod to extend outward, which in turn pushes the force-bearing inclined block, activating the alarm bell. At the same time, the alarm is broadcast through the broadcast communication wiring inside the duty room. This design effectively locks the door and prevents the theft of the emergency telephone inside the telephone box.

[0018] 2. This utility model utilizes the cooperation between components such as the protective plate, rotating plate, and torsion spring of the ventilation mechanism. When the telephone box is in the locked open state during normal operation, the pressure rod moves, and the movement of the pressure rod pulls the protective plate through the support shaft, causing the protective plate to move downward through the tension spring, thereby opening the emergency telephone and allowing ventilation. This design achieves the effect of ventilation for the emergency telephone during normal operation, preventing the emergency telephone from becoming damp and affecting its service life.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
