Description

Technical Field

[0001] The present application relates to the technical field of wall-mounted smoke alarms, and in particular to a wall-mounted smoke alarm. Background Art

[0002] Smoke alarm is actually another name for smoke sensor or smoke alarm. Smoke alarm achieves fire prevention by monitoring the concentration of smoke. It uses ion smoke sensor inside. Ion smoke sensor is a technologically advanced sensor with stable and reliable operation. It is widely used in various fire alarm systems and its performance is far superior to gas resistor fire alarm. There are radioactive substances in the sensor of ion alarm that can generate electric current. When smoke particles in the smoke enter the sensor, it will disrupt the current, causing the alarm to sound. Photoelectric alarm will emit an infrared beam. When there are smoke particles in the room, the beam will be scattered onto the sensor. After the sensor senses a certain beam of light, it will sound an alarm.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0022] The present application embodiment discloses a wall-mounted smoke alarm. Figure 1 , Figure 2 , Figure 4 As shown, it includes a fixing frame 1, a connecting plate 2 is provided on the top of the fixing frame 1, the bottom surface of the connecting plate 2 is slidably connected to the fixing frame 1, two T-slots 3 are provided on the outer surface of the fixing frame 1, two T-blocks 4 are fixedly connected to the bottom surface of the connecting plate 2, and the outer surface of each T-block 4 is slidably connected to the corresponding T-slot 3. The connecting plate 2 serves as a fixing mechanism of the alarm 12. By sliding the T-block 4 on the connecting plate 2 along the T-slot 3 on the corresponding fixing frame 1, the installation position of the connecting plate 2 can be quickly found and determined, and at this time the connecting plate 2 and the fixing frame 1 will fit together.

[0023] See also Figure 2 , Figure 4 , second slots 11 are provided on both sides of the fixing frame 1, and a second plug rod 15 is inserted into the inner wall of each second slot 11. Two fixing slots 16 are provided on the upper surface of the fixing frame 1, and a push plate 14 is slidably connected to the inner wall of each fixing slot 16. The push plate 14 can slide horizontally along the corresponding fixing slot 16, and the horizontal sliding of the push plate 14 drives the corresponding second plug rod 15 to slide horizontally. When the position of the connecting plate 2 is determined, the second plug rod 15 will be on the same central axis as the corresponding second slot 11. At this time, the connecting plate 2 can be quickly fixed by plugging the second plug rod 15 into the corresponding second slot 11.

[0024] See also Figure 4 The inner wall of the fixed frame 1 is rotatably connected with a bidirectional screw 13, and the outer surface of the bidirectional screw 13 is rotatably connected with the two fixed grooves 16. Both ends of the bidirectional screw 13 are fixedly connected with a rotating wheel 10, and the outer surface of the bidirectional screw 13 is threadedly connected with the two push plates 14. By rotating the bidirectional screw 13, the rotation of the bidirectional screw 13 will simultaneously drive the two push plates 14 to move horizontally opposite or reversely along the corresponding fixed grooves 16, and thereby push the corresponding second plug rod 15 to be plugged and fixed with the second slot 11.

[0025] See also Figure 4 The sides of the two push plates 14 that are close to each other are fixedly connected to the corresponding second plug rods 15. Four adsorption blocks 9 are fixedly connected to the bottom surface of the fixed frame 1. The side of the connecting plate 2 away from the fixed frame 1 is fixedly connected to the alarm 12. The adsorption blocks 9 are evenly distributed on the bottom surface of the fixed frame 1. The fixed frame 1 can be connected and fixed to the wall through the evenly distributed adsorption blocks 9, and the setting of the alarm 12 can enable a quick response when smoke occurs.

[0026] See also Figure 1 , Figure 2 , Figure 3 The first plug rod 6 is released when the connecting plate 2 is in contact with the fixing frame 1, and the first plug rod 6 is released when the connecting plate 2 is in contact with the fixing frame 1. At this time, the spring 7 will push the first plug rod 6 to reset it under the action of its own rebound force, and under the restriction of the fixing frame 1, the spring 7 will push the connecting plate 2 to make the T-block 4 enter the corresponding T-slot 3.

[0027] See also Figure 3A first slot 8 is provided on the outer surface of the fixing frame 1, and the inner wall of the first slot 8 is plugged into the first plug rod 6. Through the plugging between the first plug rod 6 and the first slot 8, the connecting plate 2 can be quickly fixed away from the side of the T-block 4 to prevent the connecting plate 2 from being subjected to uneven force.

[0028] The implementation principle of a wall-mounted smoke alarm in an embodiment of the present application is as follows: first, pull the first plug rod 6 to make it slide horizontally along the fixing block 5 in the opposite direction of the T-block 4. At this time, the spring 7 will be compressed, and then the connecting plate 2 is placed on the fixing frame 1. The T-block 4 will be on the same horizontal plane as the corresponding T-slot 3, and the first plug rod 6 will be on the same central axis as the first slot 8. At this time, release the first plug rod 6, the first plug rod 6 will enter the first slot 8, and the spring 7 will push the connecting plate 2 under the action of its rebound force so that it drives the T-block 4 into the T-slot 3. At this time, the second slot 11 will be on the same central axis as the second plug rod 15. Then rotate the rotating wheel 10, the rotating wheel 10 will drive the bidirectional screw 13 to rotate, and the rotation of the bidirectional screw 13 will simultaneously drive the two push plates 14 to move horizontally opposite or reversely along the corresponding fixing slot 16, and thereby push the corresponding second plug rod 15 to make it plugged into the second slot 11. At this time, the alarm can be quickly installed and fixed.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
