Technical Field

[0001] This utility model relates to the field of sound and light alarm technology, specifically to a sound and light alarm. Background Technology

[0002] A sound and light alarm is an electronic product that uses sound, light, air pressure, or other means to alert or warn people to take certain actions in order to prevent or mitigate the consequences of an incident. The product is easy to install, powerful in function, and features a bright warning light and a loud horn, making it particularly suitable for road traffic incident alarms.

[0003] Existing audible and visual alarms are usually installed on walls or columns using the mounting structure provided with the casing. Different audible and visual alarms come with different mounting structures, but these structures cannot be adapted to both walls and columns simultaneously, making it inconvenient to adjust the installation according to different sizes of columns and walls. There is an urgent need to design an audible and visual alarm to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an audible and visual alarm to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sound and light alarm includes a housing with a door rotatably fitted on one side. A warning light is mounted on the top of the housing. A loudspeaker is installed inside the housing. Multiple through holes corresponding to the loudspeaker are opened on one side of the door. A voltage module and a network transmission module are installed inside the housing. Two support bases are installed on the side of the housing away from the door. Four fixing frames are provided on one side of the housing, located on both sides of the two support bases. The fixing frames are L-shaped, with the two fixing frames on either side of the support bases symmetrically distributed. Adjusting rods are slidably fitted within the fixing frames. Limit bolts are provided between the two adjusting rods and a corresponding support base. A mounting plate is mounted on one end of each adjusting rod. A mounting hole is opened on one side of the mounting plate. An arc-shaped pad is provided between one side of the adjusting rod and one side of the mounting plate.

[0007] Furthermore, a protective frame corresponding to the plurality of through holes is provided inside the cabinet door, and a drain pipe is provided at the bottom of the protective frame, which corresponds to the loudspeaker.

[0008] Furthermore, a handle is rotatably fitted on one side of the box door, and a locking block is installed at one end of the handle that passes through the box door. A locking rod is installed on one side of the inner wall of the box, and the locking block and the locking rod engage with each other.

[0009] Furthermore, the warning light includes a base mounted on the top of the housing and multiple LED lights mounted on the top of the base. The top of the base is provided with a bracket, and a lampshade is snapped into the top of the bracket. The multiple LED lights are located inside the lampshade.

[0010] Furthermore, a plurality of limiting holes are provided on one side of the adjusting rod, and the limiting bolts correspond to the limiting holes.

[0011] Furthermore, an arc-shaped plate is provided on one side of the support base, and mounting bolts are provided between the two mounting plates. The arc-shaped pad is made of rubber.

[0012] In the above technical solution, the audible and visual alarm provided by this utility model has the following beneficial effects:

[0013] The mounting plate allows for wall mounting using the mounting holes. One end of the adjusting rod moves along the fixed frame, causing the two adjusting rods to bring the two mounting plates closer together. This allows the support base and two arc-shaped pads to abut against the column for installation. This design facilitates the use of columns and walls of different sizes, making installation and adjustment convenient. The limiting bolts pass through the support base and the two adjusting rods, limiting their position. This allows adjustment of the length of the adjusting rods extending beyond the fixed frame, thus adjusting the distance between the housing and the wall. Attached Figure Description

After installation, the limit bolt 11 can be moved to release the fixation of the two adjusting rods 10, allowing the adjusting rods 10 to move along the fixing frame 9 to adjust the distance between the housing 1 and the wall. After adjustment, the limit bolt 11 is passed through the support base 8 and the two adjusting rods 10 for fixation. When installing the housing 1 around a column, first align one side of the support base 8 with the column, then remove the limit bolt 11 to release the fixation of the two adjusting rods 10. Fix the adjustment rod 10 so that one end moves along the L-shaped fixed frame 9. The two adjustment rods 10 will drive the two mounting plates 12 to move closer to each other, so that the two mounting plates 12 will drive the two arc-shaped pads 14 to abut against the periphery of the column. Then, install the limit bolt 11 back, and then set the mounting bolt 26 between the two mounting plates 12 for fixing, so that the box 1 can be installed on the periphery of the column for use. It can be installed in different positions as needed. After installation, connect the voltage module 6 and network transmission module 7 inside the box 1 to the external power cord and network cable respectively, so that the loudspeaker 4 can play voice and the warning light 3 can provide light warning according to the voice playback content.
