[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-3 As shown, this utility model provides a technical solution: a sound and light alarm, including a mounting frame 1 and a sound and light alarm body 2. A locking block 3 is fixedly installed at the bottom of the sound and light alarm body 2. A slot 4 is opened on the upper surface of the mounting frame 1. A limiting hole 5 is opened on one side of the locking block 3 and the mounting frame 1. A connecting column 6 is symmetrically fixedly installed on one side of the mounting frame 1. A round block 7 is fixedly installed on the end of the connecting column 6 away from the mounting frame 1. A sliding plate 8 is slidably connected to the outer wall of the connecting column 6. A limiting column 9 is fixedly installed on the side of the sliding plate 8 close to the mounting frame 1. A handle 10 is fixedly installed on the side of the sliding plate 8 away from the limiting column 9. A spring 11 is sleeved on the outer wall of the connecting column 6. The locking block 3 and the slot 4 are slidably connected. One end of the spring 11 is fixedly connected to the round block 7. The other end of the spring 11 is fixedly connected to the sliding plate 8. A mounting hole 16 is symmetrically opened through one side of the mounting frame 1. The limiting column 9 and the limiting hole 5 are slidably connected.

[0022] In this embodiment, by pulling the handle 10 outward, the sliding plate 8 slides on the outer wall of the two sets of connecting columns 6. During the sliding process, the sliding plate 8 compresses the two sets of springs 11 towards the two sets of round blocks 7. After a certain degree of compression, the limiting column 9 on one side of the sliding plate 8 will exit from the limiting hole 5. After exiting, the sound and light alarm body 2 can be pulled upward, causing the locking block 3 to slide upward inside the slot 4. After sliding a certain distance, the sound and light alarm body 2 can be removed for maintenance. After maintenance, the locking block 3 at the bottom of the sound and light alarm body 2 is inserted into the slot 4. After insertion, the handle 10 is released. After release, the rebound force of the two sets of springs 11 will push the limiting column 9 into the limiting hole 5, thereby fixing the position of the locking block 3 and the sound and light alarm body 2. This design allows the operator to quickly remove the sound and light alarm body 2, greatly saving maintenance time and effectively avoiding the need to use special tools to unscrew multiple bolts during later maintenance and disassembly.

[0023] Example 2: Figure 4 As shown, a fixing ring 12 is fixedly installed on the top of the sound and light alarm body 2, a circular ring 13 is installed on the outer wall of the fixing ring 12, an explosion-proof grille 14 is fixedly installed on the top of the circular ring 13, a throttle 15 is fixedly installed on the outer wall of the circular ring 13, and the circular ring 13 and the fixing ring 12 are threaded together.

[0024] In this embodiment, by aligning the ring 13 with the fixed ring 12, since the ring 13 and the fixed ring 12 are connected by a threaded design, after alignment, the handle 15 is turned. The handle 15 drives the ring 13 to rotate. Under the action of the thread, the ring 13 will gradually rotate along the outer wall of the fixed ring 12 until it fits tightly. During this process, the explosion-proof grille 14 fixedly installed on the top of the ring 13 is also securely installed in place. This design improves the safety and reliability of the sound and light alarm body 2 in special environments by installing the explosion-proof grille 14.

[0025] The working principle of this embodiment is as follows: When the sound and light alarm body 2 needs to be removed from the mounting bracket 1 for maintenance, first pull the handle 10 outward. The handle 10 drives the sliding plate 8 to slide on the outer wall of the two sets of connecting columns 6. During the sliding process, the sliding plate 8 will compress the two sets of springs 11 towards the two sets of round blocks 7. After a certain degree of compression, the limiting column 9 on one side of the sliding plate 8 will exit from the limiting hole 5. After exiting, the sound and light alarm body 2 can be pulled upward, causing the locking block 3 to slide upward inside the slot 4. After sliding a certain distance, the sound and light alarm body 2 can be removed for maintenance. After maintenance, the locking block 3 at the bottom of the sound and light alarm body 2 is inserted into the slot 4. After insertion, the handle 10 is released. After release, the rebound force of the two sets of springs 11 will push the limiting column 9 into the limiting hole 5, thereby fixing the position of the locking block 3 and the sound and light alarm body 2. Before using the audible and visual alarm body 2, first align the circular ring 13 with the fixed ring 12. Since the circular ring 13 and the fixed ring 12 are connected by a threaded design, after alignment, turn the handle 15. The handle 15 drives the circular ring 13 to rotate. Under the action of the thread, the circular ring 13 will gradually screw in along the outer wall of the fixed ring 12 until it fits tightly. During this process, the explosion-proof grille 14 fixedly installed on the top of the circular ring 13 is also securely installed in place. By installing the explosion-proof grille 14, the safety and reliability of the audible and visual alarm body 2 in special environments are improved.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
