Description

Technical Field

[0001] The utility model relates to the technical field of alarm devices, in particular to an alarm device for building equipment. Background Art

[0002] Building security refers to the safety and security of buildings and edifices. To maintain public safety, the use of security products and related products, including intrusion alarms, video surveillance equipment, access control systems, access control and firefighting equipment, and explosion-proof safety inspection equipment, is an essential means of protecting buildings. With the rapid development of high-rise buildings and other structures, security systems are essential, and security alarms are a key component of building security systems. Smoke alarms are a common alarm device.

[0003] At present, the existing alarm devices need to be installed with a mounting frame and multiple bolts for fastening. The installation process is relatively cumbersome. If the alarm device fails and needs to be disassembled for inspection and maintenance, it may increase the workload of the personnel. At the same time, there are certain limitations when fixing it in a certain area by bolts. It may be necessary to install and configure more alarm devices to cover some larger areas, which will undoubtedly increase the cost of use and reduce the practicality of the alarm device. Therefore, we propose a building equipment alarm device to solve the above problems. Utility Model Content

Among them, the motor 3, sound and light alarm 8, and smoke sensor 9 are all connected to the external power supply through the console 10. This is existing technology and will not be described here.

[0025] Furthermore, the transmission assembly includes a motor 3 arranged above the housing 11, and the output end of the motor 3 is driven and connected to the rotating rod 4. The bottom end of the rotating rod 4 is rotatably connected to the top of the housing 11, and a limiting bracket 6 is fixedly installed on one side of the motor 3. The other end of the limiting bracket 6 is adapted to the limiting groove at the top of the installation box 2. Specifically, through the setting of the limiting bracket 6, the other end of the limiting bracket 6 is in an inverted T shape, which is adapted to the limiting groove, so that the limiting bracket 6 and the motor 3 can be firmly supported by the installation box 2, and the displacement of the limiting bracket 6 is convenient.

[0026] Furthermore, the transmission assembly also includes a gear 5 arranged below the motor 3, the interior of the gear 5 is socketed with the exterior of the rotating rod 4, and one side of the gear 5 is meshed with the rack 7 away from the side of the installation box 2 through the locking teeth. Specifically, through the setting of the gear 5, the rotating rod 4 is driven to rotate by starting the motor 3, and the rotating rod 4 then drives the shell 11 to rotate, so that the sound and light alarm 8 and the smoke sensor 9 can rotate to monitor the surrounding external environment. At the same time, the rotating rod 4 also drives the gear 5 to rotate, and the rotation of the gear 5 is immediately connected with the meshing connection of the rack 7 through the locking teeth, so that one side of the gear 5 rotates on the side of the rack 7 to move, and the gear 5 then drives the motor 3 and the shell 11 to move through the rotating rod 4, and the motor 3 moves back and forth on the limit slot at the top of the installation box 2 through the limit bracket 6, while driving the sound and light alarm 8 and the smoke sensor 9 to move, thereby further improving the monitoring effect of the surrounding external environment.

[0027] Furthermore, a slot is provided at the top of one end of the connecting plate 13, and a socket connected to the card slot is provided at the top of the connecting block 1. Specifically, through the setting of the slot and the socket, the bottom end of the pull rod 15 is conveniently connected to the socket and the slot, and the connecting plate 13 is positioned.

[0028] Furthermore, the positioning assembly includes a mounting shell 14 arranged on the top of the connecting block 1. The bottom of the mounting shell 14 is open, and the bottom surface of the mounting shell 14 is fixedly connected to the top of the connecting block 1. A limit plate 16 is provided inside the mounting shell 14, and a pull rod 15 is sleeved inside the limit plate 16. The bottom end of the pull rod 15 is plugged into the slot through the socket, and the top end of the pull rod 15 passes through the top of the mounting shell 14 and is fixedly installed with a pull block. Specifically, through the setting of the pull block, it is convenient for people to hold the pull block and pull the pull rod 15 to move.

[0029] The limit plate 16 then drives the pull rod 15 to return and inserts the bottom end of the pull rod 15 into the jack and slot, thereby completing the positioning between the connecting plate 13 and the connecting block 1, thereby achieving the effect of convenient loading and unloading of the alarm device.

[0030] In summary:

[0031] By holding the pull block to drive the pull rod 15 to move upward, the pull rod 15 then drives the limit plate 16 to move upward. At this time, the limit plate 16 squeezes the spring 17, and then engages one end of the connecting plate 13 with the slot opened on one side of the connecting block 1, so that the slot of the connecting plate 13 is aligned with the socket on the top of the connecting block 1. Release the pull block to make the spring 17 lose the extrusion force and push the limit plate 16 back under the influence of elastic recovery. The limit plate 16 then drives the pull rod 15 back and inserts the bottom end of the pull rod 15 into the socket and slot, thereby completing the positioning between the connecting plate 13 and the connecting block 1, thereby achieving the effect of convenient loading and unloading of the alarm device and improving the practicality of the alarm device.

[0032] By starting the motor 3 to drive the rotating rod 4 to rotate, the rotating rod 4 then drives the housing 11 to rotate, so that the sound and light alarm 8 and the smoke sensor 9 can rotate to monitor the surrounding external environment. At the same time, the rotating rod 4 also drives the gear 5 to rotate. The rotation of the gear 5 is then connected through the engagement of the latch teeth with the rack 7, so that one side of the gear 5 rotates on the other side of the rack 7 to move. The gear 5 then drives the motor 3 and the housing 11 to move through the rotating rod 4. The motor 3 moves back and forth on the limit slot at the top of the installation box 2 through the limit bracket 6, and at the same time drives the sound and light alarm 8 and the smoke sensor 9 to move, thereby further improving the monitoring effect of the surrounding external environment and reducing the cost of use.
