Description

Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to a wall-mounted smoke alarm for fire protection engineering. Background Art

[0002] Wall-mounted smoke alarm is a common fire safety device, widely used in homes, offices, factories, shopping malls and other places. Its main function is to sound an alarm when it detects smoke from a fire, reminding people to take timely escape and fire-fighting measures, thereby protecting life and property. Wall-mounted smoke alarms usually consist of smoke sensors, control circuits, alarm devices and power supplies. The smoke sensor is responsible for monitoring the smoke concentration in the air. Once it detects that the smoke concentration exceeds the preset threshold, it will trigger the control circuit and start the alarm device to send out signals such as alarm sounds or flashing lights. The advantages of this alarm include easy installation, small footprint, high sensitivity, and low false alarm rate. At the same time, some high-end wall-mounted smoke alarms also have intelligent functions such as self-test function, low battery prompt, and network alarm, which can be more convenient for maintenance and management.

[0003] When using a wall-mounted smoke alarm, it is necessary to ensure the quality and speed of installation, and at the same time, it is also necessary to ensure the accuracy of the wall-mounted smoke alarm when in use. However, we consider that it is inconvenient to install the base and the alarm itself when installing the smoke alarm, which greatly affects the installation efficiency of the alarm and is extremely inconvenient. Therefore, there is an urgent need for a wall-mounted smoke alarm for fire protection engineering to solve the above problems. Summary of the invention

[0004] The purpose of the utility model is to provide a wall-mounted smoke alarm for fire engineering, which solves the problem in the prior art that it is inconvenient to install the base when installing the smoke alarm, and it is inconvenient to install the alarm itself, which greatly affects the installation efficiency of the alarm.

[0006] A wall-mounted smoke alarm for fire protection engineering, comprising a base, the top of the base is fixedly connected to the alarm by screws, and the top of the alarm is fixedly connected to a protective net;

[0007] Side panels are fixedly connected to both sides of the top of the base, and support rods are provided on one side of the two side panels;

[0008] Both sides of the top of the protective net are fixedly connected with fixing plates used in conjunction with the support rod, and one end of the support rod passes through the side plate and the fixing plate in sequence;

[0009] Bottom plates are fixedly connected to both sides of the bottom of the base, and a mounting plate is slidably connected between the two bottom plates, and mounting grooves are provided on both sides of the bottom of the mounting plate.

[0010] Preferably, sliders are fixedly connected to both sides of the mounting plate, and the two sliders are slidably connected to the two base plates respectively through sliding grooves.

[0011] Preferably, threaded rods are provided at the bottom of the two base plates, and threaded grooves for cooperating with the threaded rods are provided at the bottom of the base plates and the bottom of the sliding block, wherein a plurality of threaded grooves are provided at the bottom of the base plates.

[0012] Preferably, a tension spring is sleeved on one end of each of the two support rods, and one end of each of the two support rods is elastically connected to one side of each of the two side plates through the tension spring.

[0013] Preferably, a pull plate is fixedly connected to one end of each of the two support rods.

[0014] Preferably, the two sliders are clearance-fitted with the two slide grooves respectively.

[0015] The utility model has at least the following beneficial effects:

[0016] When a wall-mounted smoke alarm for fire protection engineering in the utility model is used, the base is first fixed to the required installation position, and the installation groove on the installation plate is used to fix it to the required installation position by bolts. At the same time, the installation plate can be adjusted to adjust the installation position, and finally the alarm is installed separately from the top of the base, and a protective net is used to prevent dust from affecting the sensitivity of the alarm, and a support rod is used to limit the protective net and the alarm, which greatly improves the installation efficiency and the protection of the alarm. Compared with the problem that the smoke alarm in the prior art is not convenient for installing the base and the alarm itself, which greatly affects the installation efficiency of the alarm, the method proposed in the utility model uses a protective net to prevent dust from affecting the sensitivity of the alarm, and a support rod is used to limit the protective net and the alarm, which greatly improves the installation efficiency and the protection of the alarm.
