[0029] Specifically, the fixing block 8 and the slot 6 are plug-in installed, and the buckle 5 is adapted to the limiting groove 4. The advantage is that, through the cooperation of the fixing block 8 and the slot 6, the operator inserts the fixing block 8 into the inside of the slot 6. When the buckle 5 contacts the monitoring device housing 1, the buckle 5 deforms. When the fixing block 8 is completely submerged in the inside of the slot 6, the buckle 5 returns to its original shape, so that the buckle 5 is engaged in the inside of the limiting groove 4. This allows for quick installation of the front cover 2 and facilitates maintenance after long-term use.

[0030] Specifically, the sealing ring 10 is adapted to the groove 7. The sealing ring 10 is a rubber sealing ring, and three identical sealing rings 10 are provided, distributed at equal intervals. The advantage is that, due to the good sealing performance of the rubber sealing ring, the design of the sealing ring 10 prevents water from entering the monitoring device housing 1 through the connection gap between the front cover plate 2 and the monitoring device housing 1, which could damage the electrical components inside the monitoring device housing 1 and affect the normal use of the whole. The sealing performance is high, and the design of three sealing rings 10 further improves the overall sealing performance.

[0031] Specifically, a display screen 11 is mounted on the side of the front cover 2 away from the monitoring device housing 1. A guide groove 12 is formed on the side of the front cover 2 away from the monitoring device housing 1. A protective cover 13 is mounted on the side of the front cover 2 away from the monitoring device housing 1. A guide block 14 is fixedly installed on the side of the protective cover 13 near the display screen 11. The guide block 14 and the guide groove 12 are plugged into each other. The cross-section of the guide block 14 is L-shaped. The protective cover 13 is transparent. The advantage is that, through the cooperation of the guide block 14 and the guide groove 12, the operator can insert the guide block 14 into the guide groove 12, so that the protective cover 13 completely covers the display screen 11, enabling quick installation of the protective cover 13. The design of the protective cover 13 also prevents damage to the display screen 11 from impacts, thus ensuring normal operation of the entire device and making it highly practical.

[0032] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0033] Specifically, the fixing block 16 and the slot 21 are plug-in connected, and the soft magnet 20 and the soft magnet 24 are magnetically connected. The advantage is that, through the cooperation of the fixing block 16 and the slot 21, the operator inserts the fixing block 16 into the slot 21, and then the soft magnet 20 and the soft magnet 24 attract each other, causing the rear cover 15 to fit tightly against the monitoring device housing 1, thus enabling rapid positioning of the rear cover 15.

[0034] Specifically, the locking assembly 25 includes a mounting base 2501, a rotating shaft 2502, a threaded sleeve 2503, a screw 2504, a limiting plate 2505, and a movable groove 2506. The rotating shaft 2502 is rotatably mounted on the outer surface of the mounting base 2501. The threaded sleeve 2503 is fixedly mounted on the end of the rotating shaft 2502 away from the mounting base 2501. The screw 2504 is threadedly connected to the inner surface of the threaded sleeve 2503. The limiting plate 2505 is fixedly mounted on the side of the screw 2504 away from the threaded sleeve 2503. Movable grooves 2506 are provided on the outer surfaces of the monitoring device housing 1 and the rear cover plate 15. The screw 2504 is adapted to the movable groove 2506. The diameter of the limiting plate 2505 is larger than the diameter of the movable groove 2506. The advantage is that after the rear cover plate 15 is quickly positioned, the operator can rotate the rotating shaft 2502 so that the screw 2504 is located inside the movable groove 2506. Then, the screw 2504 is rotated so that the limiting plate 2505 abuts against the rear cover plate 15, which can achieve quick fixation of the rear cover plate 15 and facilitate maintenance after long-term use.

[0035] Specifically, sealing ring 18 is adapted to groove 22. Sealing ring 18 is a rubber sealing ring, and three identical sealing rings 18 are provided, evenly spaced. The advantage is that, due to the good sealing performance of the rubber sealing ring, the design of sealing ring 18 prevents water from entering the monitoring device housing 1 through the connection gap between the rear cover plate 15 and the monitoring device housing 1, thus avoiding damage to the electrical components inside the monitoring device housing 1 and affecting its normal operation. The high sealing performance, further enhanced by the design of three sealing rings 18, improves the overall sealing performance.

[0036] Working principle: During installation, by engaging the fixing block 8 with the slot 6, the operator inserts the fixing block 8 into the slot 6. When the latch 5 contacts the monitoring device housing 1, the latch 5 deforms. When the fixing block 8 is fully submerged in the slot 6, the latch 5 returns to its original shape, allowing it to engage with the limiting groove 4. This enables quick installation of the front cover 2 and facilitates maintenance after prolonged use. Subsequently, by engaging the fixing block 16 with the slot 21, the operator inserts the fixing block 16 into the slot 21. Inside, the soft magnet 20 and soft magnet 24 attract each other, causing the rear cover 15 to fit tightly against the monitoring device housing 1, enabling rapid positioning of the rear cover 15. After rapid positioning of the rear cover 15, the operator rotates the rotating shaft 2502, causing the screw 2504 to be positioned inside the movable groove 2506. Then, the screw 2504 is rotated again, causing the limiting plate 2505 to abut against the rear cover 15, enabling rapid fixing of the rear cover 15. This facilitates maintenance after prolonged use. Subsequently, the guide block 14 and the guide groove 12 are matched... The staff inserts the guide block 14 into the guide groove 12, so that the protective cover 13 completely covers the display screen 11, which can realize the quick installation of the protective cover 13. Through the design of the protective cover 13, the display screen 11 is prevented from being damaged by impact, thus affecting the normal use of the whole. It has high practicality. During use, due to the good sealing performance of the rubber sealing ring, the design of the sealing ring 10 prevents water from entering the monitoring device housing 1 through the connection gap between the front cover plate 2 and the monitoring device housing 1, which would damage the electrical components inside the monitoring device housing 1 and affect the normal use of the whole. The sealing performance is high. The design of three sealing rings 10 further improves the overall sealing performance.
