[0002] Automatic fire alarm equipment, as a type of fire protection equipment, is commonly used in buildings to monitor fire conditions. Existing automatic fire alarm equipment mainly consists of detectors, controllers, and alarms. Detectors include heat detectors, smoke detectors, and light detectors. The controller consists of a microprocessor, memory, and display, used to receive and process signals from the detectors, diagnose the monitored environmental conditions through signal processing, and also provide human-machine interaction. The alarm is an audible and visual alarm, which is activated by the controller after the detectors detect a fire, alerting people in the building.

[0003] In existing technologies, detectors, as the main monitoring devices, are usually installed on the ceiling using screws or bolts. Although screw or bolt installation is stable, it requires multiple rotations of the screws or bolts and the use of tools, which increases the number of steps in the screw or bolt installation and removal process and also increases the workload of the staff.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] like Figure 1-5 The fire detection automatic alarm device shown includes a detector 2, a controller, and an alarm. The detector 2 is a heat detector, a smoke detector, and a light detector. The controller consists of a microprocessor, a memory, and a display. The microprocessor receives and processes the electrical signals from the detectors and diagnoses the monitored environmental conditions through signal processing. The memory stores the electrical signal data, and the display facilitates human-computer interaction. The alarm is an audible and visual alarm. After the detector detects a fire, the microprocessor controls the audible and visual alarm to alert people in the building.

[0017] A fixing plate 3 is provided on the top of the outer shell of the detector 2. Mounting blocks 4 are installed at both ends of the fixing plate 3. Two symmetrically arranged fixing blocks 1 are installed on the surface of the outer shell of the detector 2. A pull rod 5 is elastically connected to the mounting block 4. An insertion hole 15 is opened on the side of the fixing block 1, and one end of the pull rod 5 is inserted into the insertion hole 15. A through hole 14 is provided on the side of the mounting block 4. A pull rod 5 is slidably installed in the through hole 14, and a tension spring 10 connects the pull rod 5 and the through hole 14. Fixed rings 16 are installed at both ends of the through hole 14. The pull rod 5 is inserted into the inner holes of the two fixed rings 16. A movable block 13 is fixedly fitted onto the surface of the pull rod 5. The two ends of the tension spring 10 are respectively installed on the surfaces of the movable block 13 and one of the fixed rings 16. When installing the detector 2, the two pull rods 5 are pulled first. When one end of the pull rod 5 moves into the inner hole of the fixed ring 16, the pull rod 5 pulls the movable block 13 to move synchronously. The movable block 13 applies a pulling force to the tension spring 10, causing it to extend. At this time, the... The detector 2 is placed between the two pull rods 5. Then, the force of the pull rods 5 is removed, and the pull rods 5 are reset under the elastic potential energy of the tension spring 10, making it easy to insert one end of the pull rod 5 into the socket 15. After the two pull rods 5 are pushed into the socket 6 at the same time, the position of the detector 2 is fixed. Conversely, when it is necessary to remove the detector 2, simply pull one end of the two pull rods 5 in turn to move them out of the two sockets 6, and then pull the detector 2 down. This facilitates the disassembly and assembly of the detector 2 and makes the operation easier for the staff.

[0018] The top of the fixing plate 3 has two through-holes 9, in which conductive springs 7 are installed. The outer shell of the detector 2 has two conductive posts 6 installed, and the surfaces of the two conductive posts 6 are in contact with the surface of the conductive springs 7. The detector 2 is connected to the two conductive posts 6 by two wires respectively. A wiring block 8 is installed on the top of the conductive springs 7. A wire through hole 11 is passed through the side of the wiring block 8. A stepped screw hole 12 communicating with the wire through hole 11 is opened on the top of the wiring block 8. A fastening screw is threaded in the stepped screw hole 12. The end of the fastening screw corresponds to the position of the conductive springs 7. When fixing the wires, the wires are first placed in the wire through hole 11, and then the fastening screw is rotated. The fastening screw rotates in the stepped screw hole 12, which makes it easy for the end of the fastening screw to press on the conductive end of the wire, and then press the conductive end of the wire tightly against the surface of the conductive springs 7. After the conductive springs 7 and the conductive posts 6 are in stable contact, the wires are easily electrically connected to the detector.

[0019] Both the terminal block 8 and the fastening screw are made of polytetrafluoroethylene (PTFE) plastic. PTFE plastic has certain rigidity, high temperature stability and insulation, which improves the stability of the wires when the fastening screw is installed in the terminal block 8.

[0020] Working principle: Before installing the detector 2, connect the two wires connected to the controller to the two conductive springs 7 respectively. During operation, first insert the conductive end of the wire into the wire through hole 11, then turn the fastening screw. The fastening screw rotates in the stepped screw hole 12, which makes it easy for the end of the fastening screw to press against the conductive end of the wire, thereby pressing the conductive end of the wire tightly against the surface of the conductive spring 7. After the conductive spring 7 and the conductive post 6 are in stable contact, the fixing plate 3 is installed on the surface of the wall or ceiling by screws. Next, pull the two levers 5. When one end of the lever 5 moves into the inner hole of the fixed ring 16, the lever 5 pulls the movable block 13 to move synchronously. The movable block 13 applies tension to the tension spring 10 and extends. At this time, the detector 2 is placed between the two levers 5. During the movement of the detector 2, the detector 2 drives the two conductive posts 6 to move into the two mounting holes 9. After the detector 2 moves to the position between the two levers 5, the surfaces of the two conductive posts 6 are in close contact with the conductive spring 7. At this time, the wire connected to the controller is electrically connected to the detector 2, so that the electrical signal detected by the detector 2 can be transmitted to the controller through the conductive posts 6 and the conductive spring 7. Next, the force of the pull rod 5 is removed, and the pull rod 5 is reset under the elastic potential energy of the tension spring 10, making it easy to insert one end of the pull rod 5 into the socket 15. After both pull rods 5 are pushed into the socket 6 at the same time, the position of the detector 2 is fixed.
