The pull rope assembly 400 connects the rod units 520 together. When the cabinet door is opened, the total length of the pull rope assembly 400 increases, the splicing rod assembly 500 bends, causing the angle of the alarm component 600 to change, thereby triggering the alarm. This achieves the technical effect of good alarm effect of the base station alarm device. Example

[0074] like Figure 1 As shown, the alarm device applicable to security network communication equipment is positioned on the storage cabinet 200 and includes a pull rope assembly 400, a splicing rod assembly 500, and an alarm assembly 600.

Each rod unit 520 has a central hole 521 whose axis coincides with its own axis, and the central hole 521 penetrates the entire rod unit 520. The top and bottom of the rod unit 520 are both arc surfaces, namely the top arc surface 522 and the bottom arc surface 523, which can cooperate with each other. The bottom arc surface 523 can cooperate with the top surface of the base rod 510, and the bottom arc surface 523 can cooperate with the bottom surface of the top rod 530.

The sound-emitting unit 630 is preferably a speaker capable of emitting an alarm sound. The power supply component 640 is used to provide power to the light-emitting unit 620 and the sound-emitting unit 630 and is preferably a battery. The circuit connection component 660 serves to connect the circuit between the power supply component 640 and the light-emitting unit 620 and the sound-emitting unit 630 in a timely manner, thereby causing them to issue an alarm.

When inspection and maintenance are required, the operator first sits on the aerial work platform and holds the alarm assembly 600 or fixes the alarm assembly 600 on the aerial work platform, and then opens the cabinet door for inspection.

[0085] If a theft occurs, the thief opening the cabinet door 220 will cause the pull rope 420 to lose the fixation of the compression block 450; at this time, the splicing rod assembly 500 will bend due to factors such as wind and its own center of gravity (the bending force overcomes the elasticity of the elastic rope 410 and stretches the elastic rope 410), and the alarm component 600 will sound an alarm; at this time, even if the cabinet door 220 is closed or the elastic rope 410 is cut, the alarm will not be eliminated.

Example

[0089] To further prevent thieves from damaging the alarm component 600 after opening the cabinet door (the height of the alarm component 600 reduces the risk of damage to some extent), thus affecting the alarm (stopping the alarm from functioning), this embodiment adds an automatic ejection component 700 to the above embodiment, and provides a buffer airbag 680 on the support frame 610 to prevent the alarm component 600 from being damaged by impact; after the splicing rod assembly 500 is bent to a specific angle (preferably 30 degrees), the alarm component 600 is ejected and the alarm continues to function; specifically:

One end of the pull rope 724 is fixed on the limiting plate 721, and the other end is fixed on the base rod 510. Under normal conditions, the limiting plate 721 extends out of the guide frame 722 to restrict the sliding plate 730 from sliding. When the splicing rod assembly 500 is bent to a specific angle (preferably 30 degrees), the limiting plate 721 is pulled away from the sliding plate 730.

[0091] Preferably, a wireless signal transmitter 650 is fixed on the carrier frame 610, which continues to transmit alarm signals after the signal shielding area is popped out.

[0092] Preferably, multiple alarm components 600 in a base station are connected together by an elastic rope, and when one of them alarms, a short-term group alarm will be triggered. Example

After the cabinet door 220 is closed, it controls the air pump 810 to run for a specific time (inflating the bag-shaped pull rope 420) and then stops running. The one-way valve 830 is positioned on the air outlet of the air pump 810. The air pump 810 is connected to the bag-shaped pull rope 420 through an air supply pipe. The air supply pipe and the bag-shaped pull rope... The pull rope 420 is connected to a ring magnet assembly 840, which consists of two ring magnets, namely a first magnet 841 and a second magnet 842. The two are fixed to the gas supply pipe and the bag-shaped pull rope 420 respectively, and can be attracted together. At least one of them is equipped with a sealing ring 850.
