Meanwhile, the clamping mode of limiting plate 603 and hoop 9 also simplifies the installation and disassembly process, improves work efficiency, second gear 10 is equipped with lock cylinder 4, lock cylinder 4 drives second gear 10 to engage the clamping tooth 201 of rotary disc 2, then makes rotary disc 2 rotate, rotary disc 2 rotates simultaneously and drives first gear 8 to rotate, through the hoop 9 on first gear 8 clamps or releases the pull rod 604 of alarm lamp 6, this design realizes the fixed and release of alarm lamp 6 through the simple rotation operation of lock cylinder 4, greatly improves the convenience and efficiency of operation. Meanwhile, because gear transmission mechanism is adopted, the rotation of rotary disc 2 is more stable and accurate, thereby ensuring the accuracy and stability of the position of alarm lamp 6.

[0044] Working principle:

[0045] Rotary disc 2 is limited through sliding slot 202 and the limiting block 501 on bottom cover 5, ensure that rotary disc 2 can stably rotate and be positioned at the required position during installation. The pull rod 604 of the alarm lamp 6 is clamped and fixed through the clamping groove 901 of the hoop 9, and this clamping mode enables the alarm lamp 6 to be quickly and firmly installed on the device.

[0046] The lock cylinder 4 drives the second gear 10 to engage with the clamping tooth 201 of the rotary disc 2, and this design allows the position of the rotary disc 2 to be adjusted through a simple rotation operation, thereby achieving the installation and adjustment of the alarm lamp 6.

[0047] The through holes 7 through the top cover 1, the rotary disc 2, and the bottom cover 5 provide a path for the pull rod 604 to pass through, allowing the limiting plate 603 of the alarm lamp 6 to be fixed through these through holes 7. This design simplifies the installation process and reduces the steps and tools required for installation.

[0048] By rotating the lock core 4 in the opposite direction, the second gear 10 can be separated from the clamping teeth 201 of the rotating disc 2, thereby releasing the locking state of the rotating disc 2. This allows the rotating disc 2 to rotate freely, and in turn allows the pull rod 604 of the alarm lamp 6 to be released from the clamping groove 901 of the clamp 9.

[0049] Once the pull rod 604 of the alarm lamp 6 is released from the clamping groove 901 of the clamp 9, the alarm lamp 6 can be easily disassembled. At the same time, the limiting relationship between the sliding groove 202 and the limiting block 501 also allows the rotating disc 2 to be separated from the bottom cover 5, thereby further simplifying the disassembly process.

[0050] Since the device adopts a modular design, each module (such as the top cover 1, the rotating disc 2, the bottom cover 5, etc.) can be disassembled individually. This design makes the disassembly process more flexible and convenient, allowing the entire device or only part of the module to be disassembled as needed.
