[0032] Please see Figure 1-4 This utility model provides a technical solution:

[0033] A high-precision explosion-proof audible and visual alarm includes a base 1. A threaded slot 7 is opened in the middle of the upper end of the base 1. An LED alarm light 8 is fixedly connected to the middle of the upper end of the base 1. A speaker 9 is fixedly connected to the left side of the upper end of the base 1. The LED alarm light 8 and the speaker 9 are located inside the threaded slot 7. A rectangular slot 2 is opened at the upper end of the base 1. The threaded slot 7 is located inside the rectangular slot 2. Screws 3 are threaded and movable around the lower inner wall of the rectangular slot 2. Positioning holes 6 are opened at the front and rear of the lower inner inner wall of the rectangular slot 2. A quick-release outer protective frame structure 4 is movably engaged in the rectangular slot 2. An inner protective cover mounting assembly 5 is threaded and movablely connected to the base 1 through the threaded slot 7. The inner protective cover mounting assembly 5 is located inside the quick-release outer protective frame structure 4.

[0034] In this embodiment, the quick-release outer protective frame structure 4 includes a U-shaped locking plate 41. The upper end of the U-shaped locking plate 41 has threaded holes 42 extending vertically around its perimeter. Positioning pins 47 are fixedly connected to the front and rear lower ends of the U-shaped locking plate 41. Iron frames 43 are fixedly connected to the center of the upper surface of the U-shaped locking plate 41. Each of the four iron frames 43 has an arc-shaped slot 44 at its upper end. A T-shaped slot 45 is formed at the center of the upper end of each of the four arc-shaped slots 44 on the side away from the LED alarm light 8. An outer protective component 46 is movably inserted into each of the four arc-shaped slots 44. The four threaded holes 42 correspond to the positions of the four screws 3. The U-shaped locking plate 41 corresponds to the rectangular slot 2 in position and size. The U-shaped locking plate 41 is movably inserted into the base 1 through the rectangular slot 2. The card plate 41 is detachably connected to the base 1 through four threaded holes 42 and four screws 3. The two positioning pins 47 correspond to the positions and sizes of the two positioning slots 6. The lower end faces of the four iron card frames 43 are flush with the upper end face of the base 1. The outer protective component 46 includes a retaining ring block 461. An outer protective mesh cover 462 is fixedly connected to the upper end of the retaining ring block 461. Four T-shaped magnets 463 are fixedly connected to the outer surface of the retaining ring block 461 in a ring array. The retaining ring block 461 is movably inserted into the four iron card frames 43 through four arc-shaped slots 44. The retaining ring block 461 is movably engaged with the four iron card frames 43 through the four T-shaped magnets 463 and four T-shaped slots 45. The four T-shaped magnets 463 are magnetically attracted to the four iron card frames 43 respectively.

[0035] With the above solution: During installation, the positioning pin 47 at the lower end of the U-shaped clamp 41 is aligned with the positioning hole slot 6 on the base 1 and inserted to achieve initial positioning. The two are sized to match, ensuring accurate installation. Then, the U-shaped clamp 41 is movably inserted into the base 1 through the rectangular slot 2, and then fixed to the base 1 with a screw 3 through the threaded hole 42, completing the installation of the U-shaped clamp 41. When installing the outer protective component 46, the retaining ring block 461 is movably inserted into the iron clamp frame 43 through the four arc-shaped slots 44. At the same time, the T-shaped magnet 463 cooperates with the T-shaped slot 45 and magnetically attracts it, easily realizing the installation of the outer protective component 46. Thus, no complicated tools are needed, which greatly saves the time and effort of maintenance personnel in inspecting and replacing parts and improves work efficiency.

[0036] In this embodiment, the inner protective cover mounting assembly 5 includes a transparent explosion-proof inner protective cover 51. The lower end of the transparent explosion-proof inner protective cover 51 has an inner placement groove 52. The lower end of the transparent explosion-proof inner protective cover 51 is fixedly connected to an external threaded ring block 53. The external threaded ring block 53 matches the size of the threaded slot 7. The transparent explosion-proof inner protective cover 51 is detachably connected to the base 1 through the external threaded ring block 53 and the threaded slot 7. The lower end face of the transparent explosion-proof inner protective cover 51 is close to but not fixed to the upper end face of the base 1. The transparent explosion-proof inner protective cover 51 is located inside the outer protective mesh cover 462. The LED alarm light 8 and the speaker 9 are both located in the inner placement groove 52 and do not come into contact with the transparent explosion-proof inner protective cover 51.

[0037] With the above solution: when it is necessary to install the transparent explosion-proof inner cover 51, align the external threaded ring 53 at its lower end with the threaded slot 7 on the base 1. Since the external threaded ring 53 and the threaded slot 7 are sized to match, by rotating the transparent explosion-proof inner cover 51, the external threaded ring 53 can be screwed into the threaded slot 7, thereby completing the connection with the base 1. At this time, the lower end face of the transparent explosion-proof inner cover 51 is in close contact with the upper end face of the base 1, which further enhances the stability of the connection. However, the two are not fixed for subsequent disassembly. Instead, the LED alarm light 8 and the speaker 9 are placed in the inner placement slot 52 and do not contact the transparent explosion-proof inner cover 51, avoiding friction or damage caused by contact, while ensuring that the sound and light signals are transmitted without obstruction.

[0038] It should be noted that this utility model is a high-precision explosion-proof audible and visual alarm. During use, firstly, in special locations such as industrial production, petrochemical plants, and mines, when a dangerous situation occurs, such as an excessive concentration of flammable and explosive gases or an abnormal temperature triggering the connected detector, the detector transmits a signal to the high-precision explosion-proof audible and visual alarm. At this time, the LED alarm light 8 on the base 1 receives the signal and begins to flash brightly, alerting surrounding personnel with a conspicuous light. Simultaneously, the speaker 9 emits a high-decibel sound. The two work together to create a strong audible and visual warning effect. Additionally, the U-shaped locking plate 41 in the quick-release outer protective frame structure 4 is inserted into the positioning slot 6 of the base 1 via the positioning pin 47 at the lower end, achieving initial precise positioning. It is then movably connected to the base 1 via the rectangular locking slot 2 and fixed by screws 3 passing through the threaded hole 42, providing external frame protection for the entire alarm. The retaining ring block 461 of the outer protective component 46 is connected via an arc-shaped insertion... The slot 44 and T-shaped magnet 463, along with the iron frame 43, ensure convenient and secure installation. The outer protective mesh cover 462 prevents external debris from damaging internal components. The transparent explosion-proof inner protective cover 51 of the inner protective cover mounting assembly 5 is threadedly connected to the threaded slot 7 of the base 1 via the external threaded ring block 53. Its lower end face is in close contact with the base 1, providing internal protection for the LED alarm light 8 and the speaker 9. The LED alarm light 8 and the speaker 9 are placed in the inner placement slot 52 and do not contact the transparent explosion-proof inner protective cover 51, ensuring normal transmission of sound and light signals. Therefore, this high-precision explosion-proof sound and light alarm, through the synergistic effect of the base 1, LED alarm light 8, speaker 9, quick-release outer protective frame structure 4, and inner protective cover mounting assembly 5, can efficiently warn personnel in special dangerous locations with sound and light. At the same time, its convenient installation and disassembly design facilitates maintenance, and the multi-layer protective structure ensures stable operation of the equipment in complex and dangerous environments, greatly improving the level of life and property safety.
