Technical Field

[0001] The utility model belongs to the technical field of security, and particularly relates to a building security intelligent alarm device. Background Technique

[0002] The fire alarm is one of the most important means to prevent fires. Its function is to detect a large amount of smoke and trigger an alarm when a fire occurs. The sensitivity of the smoke alarm is considered according to the geographical location and the application environment, so as to achieve the desired effect of the user. Generally, it is installed inside corridors and hotels.

[0003] According to a publicly announced fire alarm device (publication number: CN214623863U), which includes a housing. The inner wall of the housing is fixedly connected with an exhaust fan. The lower surface of the exhaust fan is fixedly connected with an air intake. The upper surface of the exhaust fan is fixedly connected with an air outlet. The inner wall of the housing is fixedly connected with an insect-proof net. The upper end surface of the insect-proof net is fixedly connected with a circuit board. The lower surface of the circuit board is fixedly connected with a smoke sensor; for this fire alarm device, through the cooperation of the fixing groove, the fixing block, the pressing plate and the spring, by squeezing the housing to drive the fixing block to drive the pressing plate to squeeze the spring to contract, and then the fixing block enters the fixing groove and the spring returns to its original position, at this time, extrusion is formed. When disassembling, just pull the housing downward forcefully. The arc-shaped groove on one side of the housing squeezes the fixing block, and at this time the spring contracts, and the disassembly can be completed, which is convenient and fast, and improves the efficiency. However, in the above device, through the cooperation of components such as the housing and the exhaust fan, it is difficult to achieve the effect of clamping and positioning the alarm mechanism, resulting in the alarm being not firmly fixed and easy to fall off, which needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a building security intelligent alarm device. By rotating the rotating rod, the positioning plate on the rotating rod is driven to rotate, so that the positioning plate drives the clamping block to rotate, and then the clamping block is inserted into the gap between the two connecting blocks, thus solving the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a building security intelligent alarm device, including an alarm device. The alarm device includes a base. One side of the base is fixedly connected with a connecting block. The side of the connecting block away from the base is fixedly connected with a device sleeve. A main board is arranged inside the base. An alarm is arranged on the side of the main board away from the base;

[0007] A clamping device is arranged outside the alarm device. The clamping device includes a fixing plate. One side of the fixing plate is rotatably connected to a rotating rod. A positioning plate is fixedly connected to the circumferential surface of the rotating rod. A clamping block is fixedly connected to the side of the positioning plate away from the rotating rod.

[0009] Furthermore, the number of the rotating rods is two and they are symmetric with respect to the vertical central axis of the fixing plate. The number of the positioning plates is two and they are symmetric with respect to the vertical central axis of the fixing plate. The above design is beneficial for limiting the alarm mechanism through the positioning plates.

[0010] Furthermore, the clamping device includes a pulling block. The pulling block is arranged on one side of the positioning plate. A long rod is fixedly connected to the side of the pulling block close to the positioning plate. One end of the long rod away from the pulling block penetrates through the positioning plate and is slidably connected to the positioning plate. A short rod is fixedly connected to the end of the long rod away from the pulling block. A clamping ring is penetrated through one end of the short rod away from the long rod and is slidably connected to the clamping ring. A stop block is fixedly connected to the end of the short rod away from the long rod. The above design is beneficial for the convenient disassembly and installation of the alarm mechanism.

[0011] Furthermore, the number of the pulling blocks is two and they are symmetric with respect to the vertical central axis of the positioning plate. The above design is beneficial for limiting the positioning plate through the rotating rod.

[0012] Furthermore, the circumferential surface of the long rod is in contact with the circumferential surface of the device sleeve. The diameter of the clamping ring is the same as the diameter of the long rod. The inner diameter of the clamping ring is larger than the inner diameter of the short rod. The above design is beneficial for positioning the long rod through the clamping ring.

[0013] Furthermore, the device sleeve is located between the two long rods. The number of the clamping blocks is four, in two groups, and they are symmetric with respect to the vertical central axis of the positioning plate. The above design is beneficial for limiting the device sleeve through the long rod.

[0014] The utility model has the following beneficial effects:

[0015] Through the cooperation of the force of the rotation of the rotating rod with components such as the fixing plate, the positioning plate, and the clamping block, the utility model realizes the function of driving the positioning plate on it to rotate by rotating the rotating rod, so that the positioning plate drives the clamping block to rotate, and then inserts the clamping block into the gap between the two connecting blocks, achieving the effect of clamping and positioning the alarm mechanism and preventing the alarm mechanism from falling off.

[0016] The utility model realizes the function of restricting the displacement of the long rod by the mutual cooperation of the gravity of the snap ring and components such as the pull block, the long rod and the short rod. Specifically, by inserting the long rod into the positioning plate, the snap ring drops due to gravity, thereby blocking the hole on the positioning plate, and then restricting the displacement of the long rod, achieving the effect of convenient disassembly and installation.
